Description

  The present invention relates to a fastener for fixing a large container such as a container or a building, and in particular, the building or the like can be loaded on a vehicle and transported, and a plurality of buildings can be combined and installed in an exhibition hall or the like. The present invention also relates to a fastener that can be used.

For the transportation of various cargoes, containers that can prevent cargo damage due to wind and rain and simplify the packaging of cargoes are actively used. The container is a large, rectangular parallelepiped container having a solid structure surrounded by a strong wall surface, and columnar members extending in the vertical direction are provided at four corners of the container. And the fastener called a corner casting is attached to the upper and lower sides of the columnar member of four corners so that a container can be piled up and loaded on a ship etc. In transportation by a vehicle, a container is usually loaded on a trailer (container chassis) pulled by a tractor, and a fastener called a twist lock is engaged with a corner casting at the bottom to be fixed to the trailer.
An example of such a trailer is shown in FIG. As can be seen from the plan view, the trailer frame FR includes two main beams MB extending in parallel in the front-rear direction over the entire length, and a plurality of cross members CM connecting the main beams MB. The front portion of the frame FR connected to the tractor has a high ground clearance, and a step portion is formed between the front portion and the rear portion. In the vicinity of the stepped portion and the rear end portion of the main beam MB, bolsters BS provided with twist locks TL at both ends are provided, and the corners on the bottom surface of the container are fixed by the twist locks TL.

  Since the transport container is a large container with a robust structure, it may be modified for use in a building such as a warehouse. For example, with the development of computer networks, the number of data centers that manage large computers in a centralized manner is increasing rapidly. Some data centers include container-type data centers that are constructed by modifying containers (module type). Data center). Container-type data centers are highly air-tight, easy to protect computers by preventing intrusion of dust, and are based on containers for transportation. It has the advantage that expansion by combination is easy.

As an example of a building using a container, a data center disclosed in Japanese Patent Application Laid-Open No. 2013-19617 related to the prior application of the present applicant will be described with reference to FIGS.
As shown in FIG. 8, this data center has a box-like structure, which is a hexahedral parallelepiped as a whole, like a general container, and has a rectangular shape in plan view. Columnar members PL extending in the vertical direction are disposed at the four corners of the rectangle, and fasteners CC are fixed to the upper and lower portions of the columnar member PL. Inside the data center, a plurality of racks LC containing computers such as servers are accommodated (in the side view of FIG. 8, the side walls of the box structure are shown).

  The fastener CC used in this data center is a metal fitting similar to the corner casting placed at the corner of the marine container. As shown in FIG. 9, the fastener CC has a solid rectangular solid structure in which six thick plates are combined, and is manufactured from cast steel so that it can be welded to the columnar member PL. A through hole for engaging a fastener such as a twist cone TC is formed in the thick plate on the outer surface of the data center. When the data centers are stacked or connected laterally as indicated by a two-dot chain line in FIG. 8, the twist cone TC is fitted into the through hole, and is fixed by rotating a predetermined angle. When loading on a container chassis for ground transportation, a twist lock, which is a tightening tool, is fitted into the through hole and fixed in the same manner.

JP 2013-19617 A

  Taking advantage of the fact that buildings based on containers for transportation can be easily transferred by vehicles or combined with multiple objects, it has recently attracted attention as a building for various purposes, not limited to data centers. Has been. As one of such things, it is considered that a container is remodeled to be a portable showroom that is used for display and advertisement of products at exhibitions or event venues.

  By the way, when it is used as a showroom, it is necessary to attract the eyes of a large number of visitors, so the design is particularly important. It is a structure, and all corners form a right angle, giving a very hard impression. From the viewpoint of the design of the showroom, it is often desirable to use a curve in the appearance part such as a corner to give a soft impression.

However, if a design with curved corners or the like is employed, columnar members extending in the vertical direction cannot be placed at the four corners of the container. Fasteners such as corner casting are fixed to the top and bottom of the columnar members at the four corners, but this fastener cannot be placed, and the modified showroom is transported by a trailer or stacked and added. It becomes impossible. Such inconvenience occurs not only when the container is used for a showroom, but also when a corner of a rectangular parallelepiped is used as a space for ancillary facilities of a modified building such as an outdoor unit for air conditioning. It is.
It is an object of the present invention to provide a fastener that can be relocated by a vehicle or expanded by combining a plurality of things even when the shape of the container is changed to form a building in which columnar members cannot be installed at the four corners. And

In view of the above-described problems, the present invention enables a fastener attached to the bottom of a building that can be transported by a vehicle such as a trailer to be coupled to a fastener installed in the vehicle, and an upper surface side and a lower surface side of the fastener. And a plurality of buildings are combined by coupling the columnar body to the through screw hole. That is, the present invention
“A fastener attached to the bottom edge of a building that can be transported by a vehicle,
The lower part of the fastener is provided with a bottom plate having a through-engagement hole that engages with a fastener installed in the vehicle, and
A screw block in which a through screw hole opening on the upper surface side and the lower surface side of the fastener is provided so that the through screw hole is positioned closer to the edge of the building than the through engagement hole. It is a fastener characterized by that.

  According to a second aspect of the present invention, it is preferable that the periphery of the fastener has a line-symmetric shape in a plan view so that the through screw hole is provided on a symmetrical center line.

  In addition, as described in claim 3, it is preferable that the fastener is formed to be larger as the height is closer to the edge of the building.

  According to a fourth aspect of the present invention, the fastener includes a peripheral portion in which a plate-like material is arranged in the vertical direction, and the screw block is coupled to the peripheral portion by a rib body in which the plate-like material is arranged in the vertical direction. It is preferable to be configured. In this case, as described in claim 5, the bottom plate formed with the through-engagement hole is coupled to the peripheral portion, the screw block, and the rib body, and a ceiling plate is provided above the bottom plate. When installed and transporting the building by the vehicle, the fastener can be accommodated between the bottom plate and the ceiling plate.

  When the fastener of the present invention is attached to a building, a plurality of buildings can be combined by connecting the columnar body to the through screw hole. As the columnar body, as described in claim 6, it is preferable that a connecting member fixed with a screw body screwed to the through screw hole is separably fitted to both ends.

  The fastener of the present invention is attached to the bottom of a building in which a container for transportation is remodeled into a showroom or the like, and the four corners of the rectangle are removed in plan view and changed to a curved portion or the like. The bottom plate provided in the lower part of the fastener of the present invention is formed with a through-engagement hole, and a fastener such as a twist lock for fixing the container to the trailer can be engaged therewith. Therefore, it is possible to fix the building to a vehicle such as a trailer like a normal container and easily transport it to an exhibition hall or the like, or to travel on the road for the purpose of advertising.

And the screw block which formed the penetration screw hole opened to the upper surface side and the lower surface side is provided in the fastener of this invention. For example, a commercially available eyebolt (bolt having a ring-shaped head) is screwed to the through screw hole from the upper surface side, and a hook of a crane is engaged with the eyebolt. The building can be loaded and unloaded on the trailer.
In addition, when stacking a building to which the fastener of the present invention is attached up and down, a columnar body provided with screw bodies that are screwed into through screw holes at both ends is prepared. The screw body at the lower end of this columnar body is screwed to the upper surface side of the through screw hole of the lower building, and the screw body at the upper end of the columnar body is screwed from the lower surface side to the through screw hole of the upper building. To do. Thereby, an upper building is supported by the columnar body, and two buildings can be combined vertically.

  Here, the through screw hole formed in the screw block is provided so as to be closer to the edge of the building than the through engagement hole that engages with the fastener installed in the vehicle. As described above, when a building is stacked using a columnar body, the weight of the upper building acts on the columnar body via the fastener, but the distance between the edge of the building and the through screw hole is Because it is short, the moment load associated with the weight of the building is reduced accordingly (this is also true when the building is suspended using eyebolts). Therefore, the stress generated in the fastener is also reduced, and the strength can be improved. On the other hand, when the building is loaded on the trailer, the trailer frame abuts against the bottom of the building to support the weight. Does not act, and moment load associated with weight does not occur.

  The invention of claim 2 is such that the peripheral portion of the fastener has a line-symmetric shape in plan view and the through screw hole is provided on the symmetrical center line. In such a case, the stress distribution generated in the fastener due to the weight of the building is also symmetrical with respect to the strength, and the appearance of the fastener itself gives a good impression in terms of design. Moreover, when the height of the fastener is increased as the position closer to the edge of the building as in the invention of claim 3, the stress due to the moment load of the weight of the building can be made uniform.

  According to a fourth aspect of the present invention, a fastener is made of a plate-like material, and the screw block in which the plate-like material is arranged in the longitudinal direction to form a peripheral portion of the fastener and a through screw hole is formed Are combined with the peripheral portion by a rib body arranged in the vertical direction to constitute a fastener. If it does in this way, since a fastener can be comprised only by the framework which joined the plate-shaped material by welding, for example, the weight of a fastener is reduced significantly. And since the plate-shaped material is arrange | positioned in the vertical direction, even if it is a thin plate | board thickness, it can fully support the moment load of the weight of a building.

  According to a fifth aspect of the present invention, in the invention of the fourth aspect, wherein the fastener is made of a plate-like material, the bottom plate in which the through-engagement hole is formed is coupled to the peripheral portion, the screw block, and the rib body, and above the bottom plate. When the ceiling plate is installed and fixed to the vehicle, the fastener is accommodated between the bottom plate and the ceiling plate. Since the bottom plate and the ceiling plate are coupled to the rib body or the like, the strength is further improved, and an accommodation portion for a fastener such as a twist lock is secured.

The invention of claim 6 relates to a columnar body that is used when a building to which the fastener of the present invention is attached is stacked one above the other, and the columnar body is screwed into a through screw hole of the fastener. A connecting member to which a screw body is fixed is fitted to both ends in a separable manner.
When stacking a building up and down using this columnar body, with the upper building lifted by a crane, connect the connection member at the upper end of the columnar body to the through screw hole in the fastener of the upper building. Screw together from the side. To the fasteners of the lower building, the remaining columnar body parts are screwed together in advance, and the upper building is gradually lowered while aligning the positions of both, and the connecting member joined to the upper building is attached. Fit into the columnar body (see FIG. 4 described later). Thus, when the columnar body of the invention of claim 6 is used, the difficult task of screwing the fastener to the fastener while rotating the entire columnar body can be omitted, so that the work of stacking buildings is easy. It becomes.

It is a figure which shows the general fastener etc. which connect a container.

Hereinafter, the fastener of the present invention used for a structure in which a container for transportation is modified will be described with reference to the drawings. The building of this embodiment is intended to be used as a showroom for displaying products and the like. First, an outline of this building is a perspective view showing a state when it is lifted by a crane. Will be explained by.
Although the building ST is based on a container, an arched wall surface AR having a semicircular curve in plan view is adopted in the front and rear portions so as to give a soft impression as a whole. . The side surface of the building ST is made of a transparent material such as polycarbonate, and it is possible to see products etc. displayed inside. In addition, a flip-up type door DR made of a transparent material is disposed on the front and back of the side surface, and it is possible to enter and exit from the inside. A transparent material is also used for the edge of the ceiling of the building ST.

  As shown in FIG. 2 which is a bottom view of the building ST, the floor portion of the building ST is a cross member extending in the lateral direction between the beam members BM extending in the front-rear direction, like a general container for transportation. It has a frame structure that spans commercials. A semicircular steel material AS that matches the planar shape of the arched wall surface AR is placed on the front and rear portions, and this is fixed to the beam material BM at the side by welding or the like. And the fastener 1 of this invention is attached to the outer side of the semicircular steel material AS by the welding etc. in the location corresponded to four corners of the building ST. Although details will be described later, a bottom plate 2 is provided at a lower portion of the fastener 1, and a through-engagement hole 21 that engages with a tightening tool such as a twist lock is formed in the bottom plate 2. That is, the position of the through-engagement hole 21 of the fastener 1 attached to the building ST is set to correspond to the position of the twist lock installed in the bolster, for example, in the trailer shown in FIG.

As shown in FIG. 3, the fastener 1 of this embodiment arranges a plurality of plate-shaped steel materials in the vertical direction (thickness portions of the plates are upper and lower surfaces), and welds these plate-shaped materials. It has a combined frame structure. That is, a plate-like material 32 bent in a parabolic shape is welded to both ends of a plate-like material 31 bent so as to correspond to the semicircular steel material AS in FIG. A cylindrical screw block 4 having a hole 41 is disposed. The screw block 4 is coupled to the peripheral portion 3 by a plurality of rib bodies 5 in which plate-like materials are radially arranged in the vertical direction.
A bottom plate 2 having a through-engagement hole 21 is provided below the tip of the parabolic plate-like material 32, and this is also welded to the side surfaces of the screw block 4 and the lower end of the rib body 5. . Above the bottom plate 2, a ceiling plate 6 having the same shape welded to the screw block 4 and the rib body 5 (however, no through hole is formed) is provided, and the screw block 4 and the ceiling plate 6 are A separate rib body 5A is also coupled. Since the fastener 1 of this embodiment basically has a frame structure in which plate-like materials are combined, it is lightweight and has high strength and rigidity.

  The peripheral edge portion 3 of the fastener 1 has a line-symmetric shape with respect to the line of the cross section AA in FIG. 3, and the through screw hole 41 is placed on the center line. The position is closer to the peripheral edge 31 than the through-engagement hole 21 and closer to the edge of the building ST. And this fastener 1 inclines so that the upper surface may become low toward the front-end | tip, Therefore, the height dimension of the plate-shaped material 32 bent by the parabolic shape and the rib body 5 is the building ST. The portion closer to the edge is set larger.

When the building ST to which the fastener 1 is fixed is lifted for loading on a vehicle such as a trailer, the eyebolt EB is screwed into the through screw hole 41 of the fastener 1 from the upper surface side as shown in FIG. Hang the hook part of the crane suspension on the part. Then, the building ST is lifted by a crane, and the through-engagement hole 21 at the bottom of the fastener 1 moves so as to match the position of the tightening tool of the trailer and is placed on the trailer. Engage the tool.
When the building ST is lifted, a load due to its weight acts on the eyebolt EB via the fastener 1, but the through screw hole 41 is provided so as to be close to the edge of the building ST. The moment load generated in the fastener 1 is small. Moreover, since the height dimension of the fastener 1 is larger than the front-end | tip part from the penetration screw hole 41 to the edge part of the building ST, the stress which generate | occur | produces in the fastener 1 by a moment load can be reduced.

  Next, a combination building in which the building ST to which the fastener 1 is fixed is stacked using a columnar body will be described with reference to FIGS. 4 and 5. FIG. 4 shows a process of superimposing the buildings ST, and FIG. 5 shows a preferred example of the columnar body used at that time.

  As shown in FIG. 4, the columnar body PB is used when stacking the buildings ST. The columnar body PB has screw bodies that are screwed to the through screw holes 41 of the fastener 1 at both ends thereof. In the columnar body PB shown in the preferred example of FIG. 5, the columnar body PB is a member extending in a straight line having a circular cross section, and provided with connecting members JT that can be separated from the main body at both ends, and the screw body PT is connected to the columnar body PB. It is fixed to the tip of the member JT. A hole is formed on the opposite side of the connecting member JT, and the connecting member JT is configured to be fitted into the main body portion of the columnar body PB in a stamping manner.

When stacking the building ST, in FIG. 4, the screw body PT of one connection member JT is screwed from the upper surface side to the through screw hole 41 of the fastener 1 of the building ST which is the lower side in FIG. The main body portion of the PB is fitted and the columnar body PB is installed in the vertical direction. At this time, in order to stably support the columnar body PB, the upper portion thereof is connected to the roof of the building ST by the bracket BK.
The other connecting member JT is screw-coupled from the lower surface side to the through screw hole 41 of the fastener 1 in a state where the building ST which is the upper side is lifted by a crane (although not shown, the upper surface is connected to the through screw hole 41). Eyebolts are screwed in from the side). Thereafter, the positions of the connecting member JT and the main body portion of the columnar body PB are aligned, and the building ST is gradually lowered, and the connecting member JT is fitted into the upper portion of the main body portion of the columnar body PB. As described above, when the columnar body shown in FIG. 5 is used, when the building ST is overlapped, only the separated connection member JT may be screwed to the fastener 1, and the operation becomes very easy.

  In FIG. 6, the example of the other combination of the building ST using the columnar body PB is shown. In this example, the structures ST whose floor surface is gradually increased are arranged radially using columnar bodies PB having different lengths. The fastener 1 of the present invention is also attached to the four corners of the building ST, but a base plate having simply screw holes is used below the columnar body PB.

  As described above in detail, the present invention enables a fastener attached to the bottom of a building to be coupled to a fastener installed in a vehicle so that it can be transported by a vehicle such as a trailer, and the upper surface side of the fastener. A through screw hole that opens to the lower surface side is provided, and a columnar body is coupled to the through screw hole so that a plurality of buildings can be combined. In the above-described embodiment, the corner is attached to a building such as a showroom having a curved shape. However, for example, the data center is a space in which the corner is cut into a straight line and ancillary equipment such as an outdoor unit is placed. Needless to say, the fastener of the present invention can be applied to other structures. Further, it is obvious that various modifications can be made to the embodiment, such as a structure manufactured by casting aluminum instead of a frame structure formed by a combination of plate-like materials.
