Description

  The present invention relates to a support floor unit of a double floor panel called a laying type and a method of constructing the floor panel using the support leg unit, specifically, four support legs for supporting four corners of the floor panel. It is related with the construction method of the double floor panel using the support leg unit which united so that it could connect and handle as one part, and this support leg unit.

  With the recent progress of office automation in offices, etc., double floor panels that enable free underfloor wiring have been proposed as floor panels with a wide variety of structures and configurations, and are also being used in various fields. However, recently, even if there is some unevenness or unevenness on the floor of the building, it is called a so-called laying type that gives priority to ease of construction using support legs that do not have a height adjustment function. Many heavy beds have been used as disclosed in Patent Documents 1 to 3.

  This laying-type double floor uses and uses one block-shaped support leg that supports the corners of the gathered four floor panels (hereinafter sometimes simply referred to as panels). Some have been devised to reduce the number of support legs.

However, the construction of a floor panel of a type that supports the gathering corners of the four assembled panels with one support leg is arranged regularly according to the size of the panel on the floor beforehand, Since it is the construction form which installs a panel on the leg, there existed a difficulty that regular arrangement | positioning of a support leg requires much effort and time especially.

  Therefore, in the present invention, it is particularly useful when applied to the laying type, and specifically, the support for the double floor panel in which the arrangement of the support legs can be greatly saved in labor compared with the conventional construction. It is an object to provide a leg unit and a method for constructing a double floor panel using the unit.

The structure of the support leg unit of the present invention, which is made for the purpose of solving the above-mentioned process, is connected and integrated by a band-like coupling body on the diagonal of the panel that supports the four corners of one rectangular floor panel from below. The four support legs are formed into a support leg unit, and the four support legs of the support leg unit are two floors laid on the left and right outer surfaces adjacent to the left and right of the panel. the panel, on the one side adjacent to the respective support legs with juxtaposed integrally coupled state the support legs for supporting the corner portions of the lower, each support leg of the can, supporting the floor panel flanked as can be coupled in the outer surface for supporting leg facing the unit, at the outer surface of each support leg, while forming a connecting portion for connecting the supporting leg units to each other by male and female fitting to the engaging relationship, Two support Between the support legs in which the bodies are arranged side by side, the corner side edge of one floor panel is inserted, and the corner side edge of another floor panel laid adjacently is inserted The support groove portion is formed .

  In the above-described configuration, the support legs at the four corners of the floor panel are connected and integrated by, for example, a belt-like combined body on the diagonal line of the panel. Each support leg is preferably formed of a single material such as synthetic resin or metal, but is not limited thereto. In addition, the support leg unit has a configuration in which the support leg units can be connected to each other on the outer surface of the support leg provided in each leg unit by the fitting or engaging relationship between the male and female. Here, there are four patterns of connection and integration with the combination of the support legs, such as the diagonal line shape of the panel, that is, the X shape, the shape of the braille shape or the combination of the square shape and the X shape. What is necessary is just a strip | belt-shaped coupling body which can connect a support leg body integrally. Further, as a coupled body, there are those formed of a band-shaped material, a bar-shaped material, a flat plate-shaped material or the like made of the same material as or different from the support leg.

  Further, in the support leg unit of the present invention, four support legs connected to each other as one part support the four corners of one floor panel, and on the left and right outer surfaces of the four support legs. In some cases, two floor panels laid next to the left and right sides have a structure in which support legs that support upper and lower corners on one side adjacent to each other are connected in parallel.

  Further, in the support leg unit, each support leg in which two support legs are arranged side by side is inserted into the corner side edge of one floor panel and another floor panel laid adjacently. The support groove part into which the corner side edge of this is inserted is provided.

Structure construction method of laying the present invention supporting leg unit having the above structure, a plurality of support legs unit coupled diagonally by two support leg is arranged strip conjugates, each support leg A step of setting a floor panel supported by the four support legs of each leg unit in the unit , and a step of arranging the diagonal lines formed by the band-like joints in each support leg unit side by side on the floor so as to form a straight line In the arrangement , the floor panel is supported in a row of the supporting leg units that are opposed to each other in the respective supporting leg units by a male-female relationship, and the row of the supporting leg units regularly arranged in the step. The floor panel is laid down on the floor surface by the step of mounting and supporting the floor panel for each of the four support legs that are not in one set.

  In the present invention, the support legs disposed under the four corners of the panel for the double floor of the laying type are provided with four support legs for supporting the four corners of the single rectangular floor panel from the bottom, and the like. As the support leg unit is formed by connecting and integrating with each other, the support legs are formed so that they can be coupled on the outer surface facing the support leg of the adjacent floor panel. The support legs to be arranged at the four corners (four places) of one panel can be arranged by a single operation, so that the laying work can be greatly saved in labor. In addition, if the supporting leg unit is made of a single material made of synthetic resin or light metal, the weight of the unit can be greatly reduced. Compared with, it greatly contributes to labor saving.

  In FIG. 1 to FIG. 5, four support legs are arranged at the four corners on the lower surface side of one floor panel P (see FIG. 10) and support the panel P from the lower surface at the four corners. Here, in the state where four hollow block-shaped bodies molded by a synthetic resin material are positioned at the four corners of the bottom surface of one floor panel P as an example so as to exhibit a substantially rectangular shape when viewed from a plane, each block shape They are combined and integrated by a flat band-like combined body 5 (hereinafter also simply referred to as a combined body 5) that forms a plane X shape that connects the main bodies in a diagonal manner. In the present invention, the support legs 1 to 4 may be formed of a material other than a synthetic resin material, for example, a metal, and the form is not limited to a substantially rectangular shape in plan view. It may be a triangle, a quarter circle, or any other planar shape. In short, any shape that can form a connecting portion (described later) with a support leg that supports an adjacent panel on the outer surface is sufficient. Further, the combined body 5 is not limited to a flat belt shape, and a bar-shaped material including a pipe, a flat plate material in which each side other than the four corners is recessed inward, or the like can be used. When the combined body 5 is flexible, it can flexibly follow the unevenness and unevenness of the floor even if the support legs are combined.

In the present invention, the connection body of the support legs 1 to 4 connected and integrated by the above-described four support legs 1 to 4 and the combined body 5 is referred to as a support leg unit UL.
In addition to the above configuration, the support leg unit UL is supported by the support leg unit UL on the left and right outer surfaces of the support legs 1 to 4 in FIG. 1 as illustrated in FIGS. In two panels P (not shown) adjacent to the left and right sides of FIG. 1 respectively, the right side of one panel P and the left side of the other panel P The support legs 11, 21, 31 and 41 for supporting the corner side edges are connected at the bottom b of the lower end with a gap g having an appropriate width as a support groove. Each of the support legs 11 to 41 has the same hollow block shape as the above support legs 1 to 4 and includes reinforcing ribs (indicated by reference numerals 3b and 31b in FIGS. 6 to 8). Further, the width of the gap g is, for example, a width that allows two side edges of the two panels P to be densely inserted together. Further, the bottom b connecting the both legs may be cut away from each other by inserting a cut line (not shown) or the like.

  That is, on the left side of the support leg 1 in the support leg unit UL of FIG. 1, the support leg 11 is symmetrical to the leg 1 and the support leg 21 is located on the left side of the support leg 2 in the same manner. The lower ends of the support legs 3 are coupled to each other with a gap g between them. On the right side of the support legs 3, the support legs 31 are symmetrical to the legs 3, and the support legs 4 in the same manner. On the right side, support leg bodies 41 are provided to be coupled to each other at the lower end portion via a gap g. In addition, circular shallow shallow dome-shaped bulging portions 1a to 4a are provided at the approximate centers of the upper surfaces of the supporting legs 1 to 4 and the supporting legs 11 to 41 integrally arranged on the legs 1 to 4, respectively. 11a to 41a are formed. These bulging portions 1a to 4a and 11a to 41a are buffer portions for relaxing the impact applied to the panel P to be placed.

  In the present invention, in the support leg unit UL, the support legs 1 to 4 support the support legs 11 to 41 that support other panels laid adjacent to the left and right outer surfaces via the gap g. The support leg units connected to each other at the bottom b are also a form of the support leg unit UL of the present invention.

Next, in the support leg unit UL, each of the support legs 1 and 11, 2 and 21, 3 and 31, and 4 and 41, which are coupled in parallel, is paired. A coupling mode through the gap g will be described with reference to FIGS. 1 to 3, and FIGS. 4 and 5.
As described above, each of the two support legs 1, 11, 2, 21, 31, 3, 31, and 41 has a gap g between the two panels P. Two of the standing wall-like side edges at the four corners are formed with a width that can be inserted densely.

  However, in the single support leg unit UL, the support legs 11, 21, 31, 41 for adjacent panels are coupled to the left and right outer sides of the four support legs 1 to 4 via the gap g. In other words, the gap g is formed to have a width that allows the side edges of two panels to be inserted simultaneously. However, the gap g can be set to only one panel P before laying.

  That is, in the floor panel laying work according to the present invention, one panel P is set to be supported by the gap g of one support leg unit UL having a gap g of a width that allows the side edges of two panels to be inserted. Even so, if the leg unit UL on which the panel is set is arranged on the floor, the support leg unit UL falls from the panel P. In other words, the gap g between the four side edges of one panel P and each of the support legs 1 to 4 in one support leg unit UL has a width corresponding to the two side edges of the two panels P. In the configuration in which only the gap g is provided, when the panel P is lifted in the air with the side edges of the four corners of one panel P inserted into the gap g, the panel P and the supporting leg unit The UL connection relationship (retention relationship) cannot be maintained.

  Therefore, in the present invention, the support leg unit UL is supported on the side edge of the support leg unit UL by elastically contacting one side wall-like side edge of the panel P with the upper portion of each gap g. The holding tongue piece 6 is provided so as to be separated or deformed by inserting the side edge of the second panel into the gap g (see FIGS. 4 to 6). .

  In the support leg unit UL provided with the structure of the holding tongue piece 6 described above, when one panel P is set on each of the support legs 1 to 4, the gaps g are formed at the four corner side edges of the one panel P. Then, it is held by the elastic force of the tongue piece 6 (see FIGS. 6 and 7). Accordingly, as illustrated in FIG. 11, when the supporting leg units UL on which one panel P is set are arranged in a checkered pattern or a staggered pattern in a single flying form, the portion with the set panel P and the panel P The part with no gap is arranged in a staggered pattern on the floor.

In addition, even if it is only the support leg unit UL of the present invention that does not have the panel P (is not set), only the support leg unit UL that does not set the panel P is arranged in the pattern illustrated in FIG. It is possible to adopt a laying mode in which the panel P is placed and supported on each support leg of the support leg unit UL.
Further, in the arrangement pattern of the support leg unit UL of the present invention not provided with the panel P illustrated in FIG. 9, the band-like combined bodies 5 forming the X shape of each unit UL are arranged in an oblique grid pattern. .

  As described above, the support leg units of the present invention provided with the panel P are arranged on the floor surface in a single line and arranged in a checkered pattern or a houndstooth pattern. As shown in FIGS. 9 and 10, the support legs 1, 11, 2, 21, 21, 3, 31 are connected to the bodies 1, 11,. 4, 41 are formed on the upper and lower outer surface sides in FIG.

In other words, in the illustrated example, the connecting portion is flat in the left support legs 1, 11, 2, 21 and the right support legs 3, 31, 4, 41 of the leg unit UL. A male member 7a having a generally reverse convex shape in view and a female member 7b having a substantially concave shape in plan view with a wall for holding the male member 7a from the front are provided on the outer surfaces in the front-rear direction of the respective support legs. . Here, a pair of support legs 1, 11,... Are provided with male and female members 7a and 7b, respectively, because a pair of support leg members 4, 41,. This is to achieve a stronger and more reliable connection by performing a symmetrical male-female connection between the two.
Each supporting leg unit UL arranged in a checkered pattern or a staggered pattern by the structure of the connecting portion (male and female members 7a and 7b) is the same as that in one leg unit UL in the example shown in FIGS. The male member 7a and the female member 7b of the support legs 3 and 31 are engaged (or fitted) from above with the female member 7b and the male member 7a of the support legs 1 and 2 in the other leg unit UL, respectively. Thus, the two leg units UL are connected (or connected) to each other.
In the present invention, the male and female members 7a and 7b can be replaced with an inverted L-shaped locking portion that is vertically symmetrical with the L-shaped section, a male and female member with a flat fastener, or the like.

  In the present invention, as shown in the plan view of FIG. 13, the bottom corners of the floor panel P are placed on the support legs 1 to 4, and the support legs 1 to 4 and the support legs 11 to 41 arranged in parallel therewith. FIG. 11 illustrates a plurality of the supporting leg units UL of the present invention in which one panel P is set by inserting the standing wall-like side edge of the panel P into the gap g formed by and supporting the holding tongue piece 6 on the gap. As described above, the female P and the male member 7a of the connecting portions facing each other in the leg units UL arranged one by one while the panels P are arranged so as to form a checkered pattern or a staggered pattern. , 7b are engaged with each other and arranged on the floor of a building where a double floor is to be formed as illustrated in FIG.

  In the state where the supporting leg units UL provided with the floor panel P are arranged in a staggered pattern as shown in FIG. 11, the outer supporting legs 11 to 41 provided integrally with the leg units UL are provided. The floor panel P is not yet placed. That is, the floor panels P are in a state where they are arranged one by one. Therefore, when the floor panel P is placed on each of the vacant support legs 11 to 41 and the side edges of the panels P are supported by the gaps g, the holding tongue 6 is attached to the panel P to be inserted later. By being separated or deformed by the side edges, the two side edges of each panel P are held in one gap g, and the floor panel P of the installation type according to the present invention is laid.

  In the above example, the leg unit UL of the present invention is arranged in a checkered pattern or in a staggered pattern so that the floor panel P is one in a state where the floor panel P is set, This is a construction example in which the floor panel P is placed in the empty space (portion where the support legs 11 to 41 are located), but the support leg unit UL with the panel P set in a staggered pattern In the case of laying (or checkered pattern), in the example of FIG. 11, the space where the panel has not yet been laid on the left and right end sides of the figure (location indicated by symbol e in FIG. 11) is a support leg. Since none of 1-4 and 11-41 are on the left side (and the right side) of the panel P in FIG. 11, in the example of FIG. Panel P cannot be placed.

Therefore, in the present invention, in the space e at the left and right end, the side wall is provided with a locking portion 8b having a substantially U-shaped cross section that can lock and support the left (and right) side edge of the panel P installed therein. The end channel 8 formed in 8a was used (see FIG. 16).
That is, as illustrated in FIG. 16, the end channel 8 is formed by connecting a plurality of the supporting leg units UL of the present invention on which the panel P is set to each other so as to form a checkered pattern or a staggered pattern. When this is done, there is no support leg (1-4 or 11-41) that occurs every other panel on the left side end (end) and right side end (end) in the arranged support leg unit UL. It has a locking portion 8b for supporting the side edge of the panel P installed in the space e, and is used outside the side ends (ends) of the left and right sides in the arranged leg unit UL. This is for covering the legs 11 to 41 which are not performed (see the left end side and the right end side in FIG. 11).

  The end channel 8 shown in FIG. 16 is provided with three cutable portions 8d that can be cut in length units of four equal in the length direction, and is formed in a substantially concave shape that is inverted when viewed from the cross section. Has been. In the unit of two segment lengths, two locking portions 8b are provided on one side wall 8a, and small holes 8c are provided at positions corresponding to the two locking portions 8b on the other side wall. Is provided. Further, in the channel 8, the length portion of one of the two division units and the engaging portion 8b and the small hole 8c in the other corresponding portion are provided symmetrically with respect to the left and right side walls 8a. The reason for this is that, in the left and right ends of FIG. 16 where the panel P is present, one side wall 8a having a small hole 8c is located, and in the space e where there is no panel P, there is an engagement. This is for the purpose of positioning the other side wall 8a including the stopper 8b.

  In the present invention, the above-described end channel 8 is not used, and the support legs 11 to 41 covered with the end channel 8 are separated from the support legs 1 to 4 because they are not used as described above. It may be arranged as a supporting leg and used as a supporting leg of the panel P. If such a use form is taken, the end channel 8 becomes unnecessary.

  In the installation of the double floor panel according to the present invention, only the supporting leg unit UL on which the panel P is not set is shown as an example, as shown in FIG. The connecting parts (male and female members 7a, 7b) of each unit UL are arranged so as to be arranged in a grid, and then the floor panel P is placed on each of the support legs 1-4 and 11-41. It is also possible to adopt a construction method.

  The present invention is as described above, and the support legs disposed at the four corners of the floor panel are formed into a support leg unit by connecting and integrating via a combined body, and each support leg is Since it is united so that it can be combined with other support legs on the outer side of each other, all the floors can be installed by simply connecting the support leg units in a staggered pattern. Support legs that support the four corners of the panel can be arranged with fewer work steps. In addition, when the support leg units are arranged one by one, the support legs that are arranged do not move because the support legs that face each other are connected by their connecting portions. The position accuracy of the entire leg can be maintained, and the support legs of the floor panel, which has a problem in work man-hours and installation accuracy, can be arranged with high position accuracy rationally and labor-saving.

  Thereby, the laying of the floor panel for forming the double floor also includes a step of arranging a plurality of support leg units side by side so that each diagonal line formed by the band-like combined body in each support leg unit forms a straight line, and A step of connecting the support legs that are in abutment with each other in the support leg units at the time of arrangement by a male-female relationship, and one support leg that is a set of four regularly arranged in the process. Since it can be constructed by the process of mounting and supporting the floor panel, it is possible to obtain the effect that the placement of the support legs and the installation of the floor panel in the construction work of the floor panel can be performed with labor saving and high positional accuracy.
