Description

TECHNICAL FIELD The present invention relates to a tent, and more particularly to a tent that is used temporarily when a building is dismantled, reconstructed, renovated, or the like.

For example, in order to dismantle a building or the like, a heavy machine such as a power shovel is used at the demolition site to destroy the building, subdivide it into small pieces, and then sort and dispose of the waste generated thereby by an appropriate method. When such demolition work is carried out in the vicinity of residential areas, hospitals, schools, etc., for example, scattering of dust is likely to occur. Since the buildings to be demolished are usually old buildings, dust containing substances harmful to health such as asbestos may be generated. may produce dust containing substances that are also unhealthy, such as dioxins. When dust, especially dust that is unhealthy, is generated, its scattering is likely to be viewed as a serious problem by residents in the neighborhood.
In addition, demolition, reconstruction, and renovation of buildings are accompanied by noise, which may cause problems with neighboring residents.
In addition, the work of dismantling and rebuilding buildings may be delayed due to the influence of rain and snow. Considering the recent situation where the cost requirements for such work are becoming more and more severe and the regulations regarding the working environment of workers are becoming more and more strict, it is desirable to eliminate such work delays as much as possible.
Although the purpose of use is various, when performing such work, the building to be demolished, reconstructed, renovated, etc. is covered with a temporary tent composed of a frame and a membrane material, In recent years, a technique of dismantling or rebuilding a building in such a state has been adopted.

A frame constituting a tent as described above is generally as follows. Frames are arranged at predetermined intervals. Each frame does not necessarily have to be so, but in most cases they are all configured identically or nearly identically. Each frame includes two posts. The pillar material is roughly a rod-shaped pillar and extends in the vertical direction. The upper ends of the two pillars are connected to each other by the roofing material, which is also a rod-shaped member. For example, the roof material may be configured on a horizontal straight line, or may be configured in a bilaterally symmetrical "dogleg shape" that is convex upward. The lower ends of the two pillars included in each frame are arranged at predetermined intervals above two imaginary straight lines that are parallel to each other and are drawn on the ground. As a result, the frames are arranged in a row at predetermined intervals.
A film material is stretched between adjacent frames among the frames arranged as described above. In addition, if necessary, a membrane material is stretched over the space surrounded by the two pillars of the frame at the extreme end and the roof material.
Temporary tents are like this, but contrary to the image usually conjured by the word tent, they are huge, sometimes exceeding 100m on a side, and sometimes exceeding 50m in height. become a thing. Although made light using membrane materials, such huge tents are very heavy, and their weight can exceed tens of tons. Therefore, for example, in order to prevent the tent from collapsing due to strong winds, the lower ends of the pillars included in the frame constituting the tent are generally firmly fixed to the ground.

By the way, the two pillars included in each of the frames that make up the tent are not made of a single rod-like body, but are made of two pillars for the purpose of increasing the rigidity while maintaining a certain degree of lightness. generally includes an inner pillar extending vertically and an outer pillar extending outward. For example, the pillar material includes two inner pillars lined up along the imaginary straight line and two outer pillars lined up along the imaginary straight line. The pillars are sometimes arranged so as to form a rectangle when viewed from above. These four outer and inner pillars are generally trussed with multiple beams between two adjacent ones to increase the strength of the pillars. target.
However, there are also problems due to the adoption of such a configuration of the pillars. Since the pillar materials as described above include inner and outer pillars, the pillar materials including the inner and outer pillars are subjected to a lateral force (when viewed from the top, two columns included in one frame direction connecting the pillars), a lateral force acts on each of the inner and outer pillars. torque) will work. The inner pillar and outer pillar included in the same pillar material are usually fixed to the same member. The foundation or the like is required to be very strong. Providing such a strong foundation or the like for a temporary tent tends to be wasteful, and if such a strong foundation or the like is provided, it is likely to cost too much to remove it.
On the other hand, temporary tents such as those described above are used for some reason, such as facilitating the construction or dismantling of tents, or convenience of work procedures such as dismantling, rebuilding, refurbishing, etc. in a building to be dismantled. , it may be convenient to move Based on this, the inventor of the present application has proposed a technique for moving the above-described temporary tent along the above-described imaginary straight line. Nonetheless, there is still room for improvement in realizing a portable tent, especially in terms of the cost of its foundation and the like.

An object of the present invention is to propose a technique for realizing a movable tent while reducing costs.

In order to solve the above problems, the inventor of the present application proposes the following invention.
The invention of the present application is designed so that the lower ends of two pillars, which are pillars extending in the vertical direction, are positioned above two imaginary straight lines, which are two imaginary straight lines parallel to each other, drawn on the ground at a predetermined interval. at least two frames having two pillar members and a roof member connecting the upper ends of the two pillar members placed at a predetermined interval, and a membrane member covering at least the space between the adjacent frames and a tent movable along the imaginary straight line. Each of the two pillar members included in each frame constituting the tent includes an inner pillar extending vertically and an outer pillar extending outward. there is
The contents specified so far may be the same as for a conventional temporary tent that is configured to be movable.
Such a tent includes an elongated first member having a horizontal surface of a predetermined width along the imaginary straight line, which can be detachably fixed with the lower end of the inner pole placed thereon, and and an elongated second member having a horizontal groove of predetermined width along said imaginary straight line into which the lower end of said outer post can be inserted. Then, when the lower end of the inner column is fixed to the horizontal surface of the first member, the lower end of the outer column is in a floating state in the groove of the second member. The inner column and the outer column whose lower end is released from the horizontal surface of the first member are lifted once and then placed in the groove of the second member, Above the roller that supports the lower end of the outer column from below and reduces the frictional force generated between the lower end of the outer column and the groove when the outer column moves along the imaginary straight line When the outer pillar is lowered, the lower end of the inner pillar is lifted from the horizontal surface of the first member.
As described above, the tent according to the present invention has a horizontal plane of a predetermined width along the imaginary straight line, which can be detachably fixed with the lower end of the inner pole placed thereon. An elongated first member and an elongated second member having a horizontal groove of a predetermined width along the imaginary straight line into which the lower end of the outer column can be inserted. ing.
The first member has, on its upper surface, a horizontal surface with a predetermined width along the imaginary straight line (the width does not need to be the same in all parts in the length direction), and is composed of, for example, a plate. A lower end of the inner column can be connected to a horizontal surface provided on a plate or the like. As will be described later, the fixation between the inner post and the horizontal surface of the first member may be released, so the fixation between the lower end of the inner post and the horizontal surface of the first member is like screwing using bolts and nuts. is releasable. At times other than when the tent is moved, the lower ends of the inner pillars included in the pillars forming the frame are fixed with respect to the horizontal surface of the first member. By fixing the lower ends of the inner pillars to the horizontal surface of the first member, the pillars are fixed to the first member, thereby achieving reliable fixation of the frame to the ground.
The second member has an elongated groove along an imaginary straight line which is open upward and into which the lower end of the outer column can be inserted. The width of the groove is a predetermined width, and the width need not be the same at all portions along its length. The second member can be made of H-steel, for example, and is arranged outside the first member. As mentioned above, when moving the tent (including when the tent is actually moving, preparing to move, and fixing the tent again after moving the tent) ), the lower ends of the inner pillars included in the pillars forming the frame are fixed with respect to the horizontal surface of the first member. At that time, the lower end of the outer column in the column material including the inner column is inserted into the groove of the second member located outside the first member to which the inner column is fixed. However, the outer post, including its lower end inserted into the groove, is not fixed to the second member, and as a result, when the inner post is fixed to the first member, the lower end of the outer post is in the groove. It becomes floating. At this time, since the outer pillar is not fixed to the second member, even if the pillar material having the inner pillar and the outer pillar is fixed to the first member, it will not be fixed to the ground through the first member. Since there is only an inner pillar and the outer pillar is not fixed to the ground, even if a lateral force acts on the pillar material, a large force (torque) does not act on the lower end of the outer pillar. Therefore, since excessive strength is not required for the first member, the second member, or the members for fixing them to the ground, such a tent is advantageous in terms of cost. In addition, as described above, the lower ends of the outer posts are inserted into the grooves of the second member except when the tent is moved. Therefore, if a lateral force acts on the pillar and the outer pillar is tilted, the lower end of the outer pillar inserted into the groove or its vicinity interferes with the inner surface of the groove, causing the pillar to tilt. prevents it from tilting any further. In this way, in the present invention, the cost of constructing a tent is suppressed by differentiating the roles of the outer pillars and the inner pillars included in the pillar materials.
On the other hand, this tent is moved as follows. When moving the tent, first, the fixation of the lower end of the inner post to the horizontal surface of the first member is released. Then, the inner column and the outer column whose lower ends are released from the horizontal plane are once lifted upward using an appropriate means such as a jack. Then, with the inner and outer columns being lifted, the rollers are inserted into the grooves of the second member, and the outer columns are lowered onto the rollers. The outer pillar is placed on top of the roller. The roller is for reducing the frictional force generated between the lower end of the outer column and the groove. When the lower end of the outer pillar rests on the roller, the inner pillar is in a state of floating from the horizontal surface of the first member. In this state, the inner pillars included in the pillar materials forming the frame are floating, and the outer pillars are on the rollers. If the inner pillars of the two pillars included in all the frames that make up the tent are in a floating state and the outer pillars are in a state of riding on the rollers, then at least a part of the tent, for example, the above-mentioned imaginary straight line When a force is applied in the direction along , the tent moves along the imaginary straight line while the outer pillar, whose lower end is fitted in the groove, is guided by the groove of the second member. The outer pillars also serve as guided members that are guided in the grooves during movement of the tent.
As described above, by assigning different roles to the outer and inner columns when the tent is moved and when the tent is not moved, the tent of the present invention can be moved, but the cost is reduced. be advantageous to

As mentioned above, the groove in the second member is adapted to insert the lower end of the outer post therein.
Here, although not necessarily limited to this, a plate-like body may be attached to the lower end of at least one of the outer column and the inner column.
A plate-shaped body provided at the lower end of the inner column can be used to fix the first member and the lower end of the inner column. For example, holes are drilled in appropriate positions of the plate-shaped body, and a plate as the first member is drilled with a large number of holes that can be aligned with the holes of the plate-shaped body. The lower end of the inner column can be fixed to the first member by, for example, screwing a nut onto a bolt passing through the holes while aligning the holes with the holes of the first member.
The plate-like body provided at the lower end of the outer pillar contributes to stably placing the outer pillar on the roller. Also, as will be described later, there are cases where the rollers are attached to the lower end of the outer pillar, in which case the plate-like body can be used to attach the roller to the lower end of the outer pillar.

The first member may be supported from below at a plurality of locations by inner support columns that are vertically extending columns provided at predetermined intervals. Instead of the inner support, the first member may be supported from below by a long member extending over the entire length of the first member. It could be. By supporting the first member with the inner struts as described above, the cost of the tent of the present invention can be reduced. The inner support may be connected at its lower end to a foundation that is partially fixed to the ground. The foundation can be for each inner stanchion. This also contributes to reducing the cost of the tent of the present invention.
The second member may be supported from below at a plurality of locations by outer support columns that are vertically extending columns provided at predetermined intervals. This also contributes to the cost reduction of the tent. The second member is supported from below at a plurality of locations by outer pillars, which are pillars extending in the vertical direction provided at predetermined intervals, and the outer pillars are connected to the foundation at their lower ends. may This also contributes to the cost reduction of the tent. The foundation can be for each outer stanchion.

The pillars included in each frame include inner and outer pillars as described above. One inner column and one outer column may be used, but at least one of them may be plural. For example, the pillar material includes two inner pillars arranged along the imaginary straight line and two outer pillars arranged along the imaginary straight line. The outer pillars of may be arranged so as to form a rectangle when viewed from above.
The two outer and inner columns may have a truss structure with a beam spanning between adjacent ones of them.

The roller may be detachably attached to the lower end of the outer pillar.
For example, endless rollers are known in which rollers are mounted under a plate. If general rollers are to be inserted into the grooves of the second member, a large number of rollers must be arranged in the grooves. If a roller such as an endless roller that can be detachably attached to the lower end of the outer pillar is connected to the lower end of the outer pillar, the roller will move along with the movement of the outer pillar, so a large number of rollers are arranged in the groove. no longer needed. This also contributes to cost savings when using tents.

A preferred embodiment of the present invention will now be described in detail with reference to the drawings.

The temporary tent in this embodiment is used when a building on a certain site is demolished and a new building is constructed on the same site. For example, a tent is erected so as to completely cover a building before demolition, and the building is demolished while being surrounded by the tent. Moreover, new buildings are constructed, for example, at least in part in tents.
However, the scene of using a temporary tent is not limited to the scene of rebuilding the building as described above, and the tent may be used when the building is dismantled or when the building is constructed. . Buildings include not only buildings, condominiums, factories, etc. that are intended for people to enter, but also structures that are not intended for people to enter, such as bridges, elevated roads, high-rise chimneys, etc. can be included.
Whatever the tent is used for, the temporary tent described in this embodiment can be moved as described below.

An overview of the tent is shown in the perspective view of FIG.
The tent body 1 is simply a huge tent. Although not limited to this, the tent body 1 in this embodiment is sized to completely cover a building (not shown) before dismantling. The tent body 1 is, although not limited to this, rectangular in plan view in this embodiment, and when it is large, its long side may reach 100m and its height may reach 50m.
A tent body 1 rests on a support 2 . There are two supports 2 for supporting the tent body 1, and both of them are linear. The supports 2 are provided parallel to each other so as to sandwich the building before demolition (not shown). The support 2 is arranged on virtual straight lines (not shown) that are two parallel virtual straight lines drawn on the ground at predetermined intervals.

The tent body 1 according to this embodiment comprises a plurality of bone members 10 as shown in FIGS. FIG. 2 is a diagram showing only the rib member 10 corresponding to the frame in the present invention. The rib members 10 may have basically the same structure as those in the conventional tent body 1 . Each bone member 10 is erected at a predetermined interval, but not limited to this, at equal intervals in this embodiment, and parallel when viewed from above.
Adjacent bone members 10 are connected to each other by connecting members (not shown) so that the distance between them remains constant. The connecting material connects the adjacent bone members 10 with the distance between them fixed. The configuration of the connection material is not critical as long as it can be realized, and since it can be realized by a known or known technology, the description of the configuration is omitted.
By using the connecting material, the tent body 1 is integral as a whole, and even when moving along the support 2, deformation occurs such that the spacing of the bone members 10 changes. It's not supposed to. That is, in this embodiment, when force is applied to a portion of the tent body 1 in the direction along the virtual straight line, the entire tent body 1 moves together in the direction along the virtual straight line. However, when it is desired to move only a part of the tent body 1, for example, when it is desired to move only the portion from the end of the tent body 1 to the three bone members 10 collectively, the tent body 1 can be integrally moved. Adjacent ones of the bone members 10 corresponding to the portion to be moved may be connected to each other. Also, the connection between the adjacent bone members 10 can be performed each time the tent body 1 is moved, at a portion of the tent body 1 corresponding to the portion desired to be moved as an integral unit.

Although not limited to this, each bone member 10 in this embodiment is the same. The rib member 10 serves as the rib of the tent body 1 and has the necessary rigidity. The rib member 10 is composed of a metal square pipe in this embodiment, although not limited to this.
The rib member 10 includes two rod-shaped pillars 11 and two rod-shaped beams 12 . The column portion 11 serves as a column of the tent body 1 and constitutes a part of the wall, and the beam portion 12 serves as a beam of the tent body 1 and constitutes a part of the roof. The two pillars 11 and the two beams 12 are separate members, which are combined and fixed in a state described later to form an integral rib member 10 . The column portion 11 and the beam portion 12 are further composed of a plurality of members as will be described later.
The pillars 11 are erected substantially vertically on the support 2 with a predetermined interval. The poles 11 are fixed to the support 2 when the tent body 1 does not move. The fixation is detachable. A method for fixing the column portion 11 and the support 2 will be described later.
Further, when the tent body 1 moves along the imaginary straight line, the lower ends of the pillars 11 move on the support 2 along the support 2 . How the lower end of the column portion 11 moves on the support 2 without deviating from the support 2 or guided by the support 2 will be described later.
One ends of the two beams 12 are fixed to the upper ends of the two pillars 11, respectively. Also, the other ends of the two beams 12 are connected to each other. The two beam portions 12 are arranged on a straight line when viewed from above. The other ends of the beams 12 connected to each other are higher than one end of the beams 12 . Due to the configuration of the beams 12, the roof of the tent body 1 has a so-called gable shape, although the roof is not limited to this. The beam portion 12 may be a single rod-shaped body that is bridged so as to connect the upper ends of the two horizontal column portions 11 . If such beams 12 are employed, the roof of the tent body 1 will be a flat roof. Of course, the shape of the roof of the tent body 1 is not limited to these.

Next, the sheet 20 that constitutes the tent body 1 will be described.
The seat 20 may have the same configuration as a conventional one. The sheet 20 is generally a film material made of resin, and is flexible enough to be stretched between the bone members 10 . Among the sheets 20, those stretched between the adjacent bone members 10 are rectangular long members, and the long sides thereof are supported by the adjacent bone members 10 respectively. The method of fixing the bone member 10 and the sheet 20 may follow the conventional technique.
Moreover, although not limited to this, in this embodiment, the sheet 20 is stretched over the spaces surrounded by the bone members 10 positioned at both ends of the tent body 1 . A sheet 20 stretched over a space surrounded by rib members 10 located at both ends of the tent body 1 is provided with a door 40 serving as an entrance to the tent body 1 as required.
The sheet 20 may be double stretched.
Of the contents described above, the contents of the tent body 1 can all be in accordance with the prior art, and are actually so in this embodiment.

A column portion 11 of the rib member 10 is configured as shown in FIG. FIG. 3 is a perspective view of the vicinity of the lower end of the column portion 11. As shown in FIG.
As shown in FIG. 3, the column portion 11 is made of a metal square pipe. The two square pipes on the far side are the inner pillars 11A, and the two square pipes on the front side are the outer pillars 11B. Also, the dashed lines drawn downward to the left and right are lines obtained by translating the imaginary straight line upward.
The inner post 11A is vertical and has an inner plate 11A1 attached to its lower end. The inner plate 11A1 has a rectangular shape, and its circumference protrudes outside from the inner column 11A. Inner holes 11A2, which are circular holes, are drilled at appropriate positions of the inner post 11A, such as, but not limited to, four corners in this embodiment. The inner hole 11A2 is used to fix the inner post 11A to a first member which will be described later. One side of the inner column 11A and the inner plate 11A1 is parallel to the imaginary straight line, and the center of the cross section of the inner column 11A overlaps the center of the inner plate 11A1 when viewed from above, although not limited to this. It has become.
The outer pillar 11B is vertical and has an outer plate 11B1 attached to its lower end. The thickness, length, material, etc. of the outer post 11B can be different from those of the inner post 11A, but in this embodiment, they are all the same as those of the inner post 11A. The outer plate 11B1 has a rectangular shape, and its circumference protrudes outside from the outer pillar 11B. Outer holes 11B2, which are circular holes, are drilled at appropriate positions of the outer post 11B, such as, but not limited to, four corners in this embodiment. The outer hole 11B2 is used to fix the outer post 11B to an endless roller, which will be described later. One side of the outer column 11B and the outer plate 11B1 is parallel to the imaginary straight line, and the center of the cross section of the outer column 11B overlaps the center of the outer plate 11B1 when viewed from above, although not limited to this. It has become.
The inner plate 11A1 of the inner column 11A and the outer plate 11B1 of the outer column 11B described above are not necessarily required if the inner column 11A and the outer column 11B can be fixed to the first member and the endless roller, respectively. not required.
A truss beam 11C for forming a truss structure is stretched between the inner pillar 11A and the outer pillar 11B that constitute the pillar portion 11 . In FIG. 3, for convenience of drawing, the truss beam 11C stretched between the two outer pillars 11B located in front is indicated by a chain double-dashed line. Of course, between the two inner pillars 11A located in the back, between the inner pillar 11A and the outer pillar 11B located on the left and right, and between the two outer pillars 11B located in the front, A truss beam 11C is stretched. The truss girders 11C can also be constructed of square pipes and are so in this embodiment. The truss beam 11C is basically stretched obliquely, but horizontally stretched at the bottom and top portions.
In this embodiment, each of the inner pillars 11A and the outer pillars 11B included in one pillar portion 11 is two. However, at least one inner pillar 11A and one outer pillar 11B included in one pillar portion 11 is sufficient. For example, when there is one inner pillar 11A and one outer pillar 11B, the pillar portion 11 consists of the inner pillar 11A and the outer pillar 11B (and the truss beam connecting them) located on the right side of FIG. 3, for example. become.
The column portion 11 in this embodiment is configured as described above, and the beam portion 12 that constitutes the frame member 10 together with the column portion 11 in this embodiment is also a truss beam that spans between four rod-shaped bodies. , is practically the same as that of the column portion 11 . Of course, it is not necessary to make the structure of the column part 11 and the beam part 12 the same.

Next, the structure of the support 2 will be described.
The support 2 supports the tent body 1 as described above. The tent body 1 moves along the imaginary straight line as described above. The support 2 exists over a range in which the tent body 1 moves, more specifically, over a range where the lower ends of the pillars 11 of the bone members 10 can exist when the tent body 1 moves. As a result, the support 2 becomes long.
A plan view of the support 2 is shown in FIG. 4, and a view taken along line AA in FIG. 4 is shown in FIG. Note that the right side of the support 2 shown in FIG. 4 is the inside, and the left side is the outside. The inner side is the side facing the other support 2 . That is, the support 2 shown in FIG. 4 is the support 2 located relatively to the left in FIG. The support 2 located on the relative right side in FIG. 1 has a mirror image relationship with the support 2 shown in FIG.

The support 2 has a base material 21 underneath. The base material 21 is for securely fixing the support 2 to the ground. The base members 21 are provided at predetermined positions in the longitudinal direction of the support 2 at predetermined intervals from each other. The interval between adjacent base members 21 may be constant, or may not be so. In this embodiment, although not limited to this, a large number of base members 21 are provided at both ends of the support 2 and appropriate positions in the middle thereof at regular intervals. The base material 21 is made of a strong and heavy material, for example concrete, to serve the above-mentioned purpose. The shape of the base material 21 is not particularly limited as long as the above purpose can be achieved, but in this embodiment, it is a rectangular parallelepiped shape, although not limited to this.
In this embodiment, at least part of the base material 21 is buried in the ground X, but this is also not the case. The height of the portion of each base material 21 that appears on the ground may or may not be the same. For example, if the ground is inclined in the longitudinal direction of the support body 2, the height of the portion of each base member 21 that appears above the ground is adjusted to keep the first and second members described later horizontal. It can be changed as appropriate. For example, it is possible to reduce the height of the portion of the base material 21 above the ground that is relatively higher on the ground.

On the base material 21 are provided inner struts 22 and outer struts 23, both of which extend vertically.
Inner struts 22 are provided on all base members 21 in this embodiment. The inner pillar 22 is a pillar for supporting a first member described later from below, and has a sturdiness capable of supporting it. Although not limited to this, the inner support 22 in this embodiment is a prism. As will be described later, the first member directly receives the weight of the tent body 1, so the inner struts 22 that support the first member must be very sturdy. For example, the inner stanchions 22 may be constructed of concrete, such as rebar cleats, integral with the foundation 21, as they are in this embodiment. Of course, the inner struts 22 can also be separate from the base material 21, in which case the inner struts 22 can be made of metal, for example.
Outer struts 23 are provided on all base members 21 in this embodiment. The outer struts 23 are erected outside the inner struts 22 . The outer pillar 23 is a pillar for supporting a second member described later from below, and has a sturdiness capable of supporting it. Although not limited to this, the outer struts 23 in this embodiment are prisms. As will be described later, the second member does not directly bear the weight of the tent body 1, so although it must have a certain degree of sturdiness, it does not need to be as strong as the inner struts 22. Therefore, although not limited to this, in this embodiment, the outer struts 23 are thinner than the inner struts 22, and are hidden under the second member described later in the plan view of FIG. For example, the outer struts 23 can be configured as metal bars separate from the base member 21, as they are in this embodiment. Of course, the outer struts 23 can also be integrated with the base material 21, in which case the outer struts 23 can be made of concrete, for example. In this embodiment, the structure of the outer struts 23 is different from that of the inner struts 22, but it is also possible to make both structures the same including the material.

A first member 24 is mounted on the inner support 22 .
The first member 24 is an elongated member for fixing the column portion 11, more precisely, the inner plate 11A1 of the inner column 11A included in the column portion 11. As shown in FIG. The length of the first member 24 spans the entire length of the support 2 . Of course, the first member 24 does not have to be a single body, and may be configured by connecting a plurality of divided elongated members.
The first member 24 is made of H-steel in this embodiment. More specifically, the first member 24 is used with the H-beam grooves oriented laterally. The first member 24 is horizontal along its length. On the upper side of the first member 24, a horizontal plane 24A, which is the upper surface of the plate material, is formed. This horizontal surface 24A extends over the entire length of the support 2 . The horizontal surface 24A has a predetermined width, which is not necessarily limited to this, but is the same width over the entire length of the first member 24 in this embodiment. The width of the horizontal surface 24A is, for example, somewhat longer than the length of the inner plate 11A1 of the inner column 11A in the inner and outer directions, so that the inner column 11A on the plane can be stably supported. It has become. Along both edges of the first member 24, holes 24B are drilled along the entire longitudinal length of the first member 24 at predetermined intervals, although not limited to this, at constant intervals in this embodiment. This hole is used to fix the inner post 11A, more specifically the inner plate 11A1 at the lower end of the inner post 11A, to the first member 24. As shown in FIG.

A second member 25 is mounted on the outer strut 23 .
As will be described later, the second member 25 stabilizes the tent body 1 when not moving, or the pillars 11 included in the tent body 1, and also stabilizes the tent body 1 when moving, or the tent. By guiding the pillars 11 included in the main body 1, it plays a role of stabilizing the moving tent main body 1. - 特許庁The second member 25 is elongated and extends over the entire length of the support 2 . Of course, the second member 25 does not have to be a single piece, and may be configured by connecting a plurality of divided elongated members.
The second member 25 is made of H-steel in this embodiment. More specifically, the second member 25 is oriented such that the grooves of the H-beam are oriented longitudinally. Although not limited to this, the second member 25 is fixed onto the outer strut 23 via a connection plate 26 that is a plate. The connection plate 26 is a rectangular plate that is one size larger than the cross section of the outer strut 23 . A groove 25A is formed on the upper side of the second member 25 according to the original shape of the H steel. The second member 25, which is H-steel, is horizontal in the longitudinal direction, and the groove 25A is also horizontal. This groove 25 A extends over the entire length of the support 2 . This plane has a predetermined width, which is not necessarily limited to this, but is the same width over the entire length of the second member 25 in this embodiment. The width of the groove 25A is the same as or slightly longer than the length of the inner and outer plates 11B1 attached to the lower end of the outer post 11B, thereby allowing the lower end of the outer post 11B or its attachment thereon. The outer plate 11B1 thus formed can be inserted into the groove 25A. The outer plate 11B1 inserted into the groove 25A basically keeps horizontal.
The distance from the center of the groove 25A of the second member 25 in the width direction to the center of the horizontal surface 24A of the first member 24 in the width direction is from the center of the inner column 11A included in the same column portion 11 to the center of the outer column 11B. is equal to the distance of
A supporting plate 27 is attached between the first member 24 and the second member 25 so as to connect them. The support plate 27 is, but not limited to, rectangular in this embodiment. The support plate 27 is horizontal in this embodiment, although not limited to this.

The use and operation of such a tent will now be described.
First, the state in which the tent body 1 is fixed will be described.
The tent body 1 may be fixed to two supports 2, as already explained with reference to FIG.
In that case, the two pillars 11 included in each bone member 10 constituting the tent body 1 are fixed to the two supports 2, respectively.
FIG. 6 shows the relationship between the support 2 and the column 11 in that case. FIG. 6 is a diagram showing the vicinity of the lower ends of the support 2 and the column portion 11 as seen from the direction of arrows AA in FIG.
As described above, the column portion 11 includes the inner column 11A and the outer column 11B.
Of these, two inner posts 11A, more specifically, inner plates 11A1 attached to the lower ends of the two inner posts 11A, respectively, ride on the horizontal surface 24A of the first member 24. As shown in FIG. In this state, the inner plate 11A1 and the first member 24 are fixed to each other. When performing such fixing, the four inner holes 11A2 provided in the inner plate 11A1 and four of the numerous holes 24B drilled in the horizontal surface 24A of the first member 24 are aligned. By screwing nuts 32 onto the four bolts 31 that collectively penetrate the inner hole 11A2 and the hole 24B, the inner plate 11A1 and the first member 24 are separated between the heads of the bolts 31 and the nuts 32. A plate having a horizontal surface 24 is clamped together. As a result, the inner plate 11A1 fixed to the lower end of the inner column 11A is fixed to the first member 24, thereby fixing the lower end of the column portion 11 including the inner column 11A to the support 2. At this time, as shown in FIG. 6, the outer plate 11B1 attached to the lower end of the outer pillar 11B is in the groove 25A of the second member 25, but is in a floating state.
The fixing of the pillars 11 to the support 2 as described above is performed by both the pillars 11 of all the bone members 10 . Moreover, the fixation of the column portion 11 to the support member 2 is released by releasing the screwing of the bolt 31 and the nut 32, and is detachable.
When the pillars 11 are fixed to the support 2 in the above-described state, the weight of the tent body 1 is transferred from the inner pillars 11A constituting the pillars 11 through the first member 24 and the inner pillars 22, It hangs on the base material 21 . That is, the weight of the tent body 1 is mainly supported by the inner pillar 11A and the first member 24. As shown in FIG. On the other hand, in this state, although the outer plate 11B1 attached to the lower end of the outer pillar 11B is in the groove 25A of the second member 25, it is in a floating state, so that the tent body 1 is in a crosswind. Even if a lateral force acts on the pillar part 11 by receiving the Therefore, the torque as described in the background art section does not occur. However, since the outer plate 11B1 at the lower end of the outer column 11B is inside the groove 25A of the second member 25, if the inner column 11A included in the column portion 11 tilts more than a certain amount, the outer plate 11B1 will move into the groove 25A. Further inclination of the column portion 11 is suppressed by being engaged with the inner surface of the column portion 11 .
In this manner, the tent body 1 can be firmly fixed to the support 2 by having the inner pillars 11A and the outer pillars 11B play different roles.

Next, the case of moving the tent body 1 will be described.
In that case, the fixation of the rib member 10 constituting the tent body 1 to the support 2 is released. As described above, the tent body 1 may be moved as a whole, but may be partially moved (for example, from one bone member 10 to another bone member 10). Of the bone members 10 included in the tent body 1, the bone members 10 included in the range to be moved are targeted for releasing the fixing to the support 2. As shown in FIG.
To release the fixation of the bone member 10 and the support 2, the bolt 31 and the nut 32 are unscrewed, and the bolt 31 is pulled out from the inner hole 11A2 and the hole 24B.
Next, the bone member 10 that has been released from the support 2 is lifted somewhat upward, for example, by jacking it up. It is up to you where to jack up the rib member 10, but in this embodiment, the jack 50 is placed on the above-described support plate 27 that spans between the first member 24 and the second member 25. At the same time, the jack 50 pushes up the horizontal truss beam 11C provided near the lower ends of the inner pillar 11A and the outer pillar 11B included in the pillar 11 located above the support plate 27. 11 and thus the entire bone member 10 is jacked up. Although not limited to this, in this embodiment, the two pillars 11 included in the same bone member 10 are simultaneously jacked up. All the pillars 11 included in the member 10 are jacked up at the same time.
Note that the jack 50 can be a known or well-known one, and its usage can also be a known or well-known one.

Then, the tent main body 1 is in a state of floating from the support body 2. - 特許庁In this state, the inner plate 11A1 at the lower end of the inner post 11A is in a state of floating from the horizontal surface 24A of the first member 24. As shown in FIG. Further, the outer plate 11B1 at the lower end of the outer post 11B may be positioned in the groove 25A of the second member 25 or may be positioned above the groove 25A.
In that state, the rollers are placed in the grooves 25A, or the endless rollers are attached to the lower surface of the outer plate 11B1 located at the lower end of the outer post 11B. When the rollers are placed in the groove 25A, a large number of rollers are arranged at least within the range in which the column portion 11 moves in the length direction of the groove 25A. In this embodiment, the endless roller 35 is attached to the lower surface of the outer plate 11B1 positioned at the lower end of the outer column 11B, which is the object of movement and which is slightly lifted by jacking up.
The endless rollers 35 are attached to the lower surfaces of all the outer plates 11B1 of the outer pillar 11B which are slightly raised by jacking up. The endless roller 35 is a roller attached to the bottom of a plate, and can be known or well-known. Simply put, the endless rollers 35 are like replacing the wheels of a trolley with wheels attached to the bottom of a plate with rollers. As the endless roller 35, for example, an endless roller (trade name: Chiltank (trademark) type 3) manufactured and sold by Katsuyama Machinery Co., Ltd. can be used. The method for attaching the endless rollers 35 under the outer plate 11B1 may be a publicly known or well-known method.
After the endless rollers 35 are attached to all the outer plates 11B1 of the outer column 11B included in the slightly raised rib member 10, the jacked-up rib member 10 is lowered. In the case of lowering the bone member 10, although not limited to this, in this embodiment, two pillars 11 included in the same bone member 10 are lowered at the same time, and more preferably, the tent body 1 is lowered. All of the columns 11 included in the bone member 10 to be moved are lowered at the same time. FIG. 7 shows the bone member 10 lowered.
The inner plate 11A1 at the lower end of the inner column 11A in each column portion 11 included in the lowered bone member 10 is still floating from the horizontal surface 24A of the first member 24 even when the bone member 10 is lowered. The extent to which the inner plate 11A1 should be lifted from the first member 24 may be determined as appropriate, but it is sufficient if it is lifted by 10 mm, for example.
On the other hand, the outer plate 11B1 at the lower end of the outer column 11B in each column portion 11 included in the lowered bone member 10 is put on the endless rollers 35 when the bone member 10 is lowered. Of course, at this time, the bottom surface of the roller included in the endless roller 35 is in contact with the bottom of the groove 25A. Further, the outer plate 11B1 is positioned inside the groove 25A of the second member 25. As shown in FIG.
Before and after jacking up, the first member 24 and the inner plate 11A1 respectively produce the above-described states, and before and after jacking up, if the second member 25 and the outer plate 11B1 respectively produce the above-described states, then the inner post 11A and the length of the outer column 11B, or the height of the inner plate 11A1 and the lower surface of the outer plate 11B1 do not need to match, and the height of the horizontal surface 24A of the first member 24 and the groove 25A of the second member are It doesn't have to be the same relationship.

In that state, the portion of the tent body 1 to be moved is moved. For this purpose, at least one of the bone members 10 included in the portion of the tent body 1 to be moved should be applied with a force along the imaginary straight line by, for example, a heavy machine. How such a force is applied to the bone member 10 is known or known in the art.
When a force such as described above is applied, the portion of the tent body 1 to be moved moves along the imaginary straight line in the direction of the applied force. At that time, since the endless roller 35 exists on the lower surface of the outer plate 11B1 located at the lower end of the outer column 11B included in the column portion 11, the grooves of the outer plate 11B1 and the second member 25 are formed. The frictional resistance between 25A is small. Therefore, the tent body 1 can be moved with a relatively small force. In addition, since each outer plate 11B1 is guided by the groove 25A provided in the second member 25 extending in the direction along the imaginary straight line, the movement of the tent body 1 is stabilized.

Once the portion of the tent body 1 to be moved has been moved to the desired position, the bone members 10 included in the moved portion of the tent body 1 are again moved in the same manner as described above. Then, all the endless rollers 35 are removed from the outer plate 11B1 located at the lower end of the outer column 11B in a state that the rib member 10 is lifted.
Then, the rib member 10 is lowered again, and the inner plate 11A1 of the inner plate 11A1 is fixed to the first member 24 using the bolts 31 and nuts 32 in the same manner as described above. The bone member 10 and the support 2 then return to the state shown in FIG. Thereby, the displaced portion of the tent body 1 is fixed again to the support 2 in the displaced position.
If only a part of the tent body 1 has been moved, the entire tent body 1 can be moved by repeating the above-described process.
