Description

The present invention relates to a connector and a temporary structure construction set used to construct various temporary structures at construction sites and the like, as well as a method for constructing temporary structures.

When heavy objects are brought to a construction site, temporary structures are sometimes constructed using materials such as various shapes of steel beams (channel steel, L-shaped steel, etc.), support structures, and brackets (L-shaped mounting fixtures). Such temporary structures can be constructed in a variety of ways depending on the conditions at the site where the various items are to be brought in, and the size and weight of the items.

Figure 1 shows an example of a conventional method for constructing a temporary structure. H-shaped steel 62, which serves as the main girder, is placed on a pair of structures 60 that serve as the supports of the temporary structure, and steel plates or the like are laid on the H-shaped steel 62 to form a deck, and a route for transporting heavy objects is constructed. Also, as shown in Figure 1, connectors 64 of various shapes may be used to connect shaped steel such as channel steel 70 while preventing the structure from buckling.

Figure 2 is an enlarged view of the area enclosed by the two-dot chain line in Figure 1. According to the prior art, when fixing H-shaped steel 62 to a structure 60 via a conventional bracket 64 using bolts 66 and nuts 68 to connect shaped steel such as H-shaped steel 62 to the structure 60, it is necessary to drill new bolt holes in the structure 60, H-shaped steel 62, and bracket 64 each time depending on the size of the work site, which can accelerate the wear of each material. Or, when the structure or shaped steel is a rental item, it is sometimes necessary to connect them using only clamps because it is not possible to drill bolt holes in those materials.

The L-shaped connector, U-shaped connector, temporary structure construction set, and method for fixing structural steel to a structure of the present invention will be described below with reference to the attached Figures 3 to 12.

Figure 3 shows an example of a structure 12 formed from a plate-like metal, hard ceramic, or the like. As shown in Figure 3, a plurality of through holes 14 are formed in one or more rows at equal intervals (the center-to-center distance between adjacent holes is, for example, 50 mm) on each surface 18 forming the outer shape of the structure 12. In other embodiments, the center-to-center distance between the plurality of through holes 2 may be other than 50 mm, but even in such cases, the plurality of through holes 2 are formed to be equally spaced apart with a center-to-center distance other than 50 mm.

As shown in FIG. 3, the structure 12 has a polygonal prism (e.g., a rectangular parallelepiped) outer shape and has a hollow portion penetrating each face 18 of the polygonal prism. In another embodiment, the structure 12 is an H-shaped support having a roughly H-shaped cross section formed from a plate-like metal material or the like, and a plurality of through holes may be formed at equal intervals on a predetermined portion of the surface of the H-shaped support. In yet another embodiment, the structure 12 is a U-shaped support having a roughly U-shaped cross section formed from a plate-like metal material or the like, and a plurality of through holes may be formed at equal intervals on a predetermined portion of the surface of the U-shaped support. The L-shaped connector 1 and U-shaped connectors 4 and 6 as connectors for connecting existing steel beams to such a structure 12 are described below.

Figure 4 shows the L-shaped connector 1 of the present invention. In one embodiment, a plurality of through holes 2 are formed on one surface of the L-shaped connector 1 in one or more rows at equal intervals (the center-to-center distance between adjacent holes is, for example, 50 mm). Furthermore, a plurality of through holes 2 may also be formed on a surface perpendicular to the above-mentioned surface in one or more rows at equal intervals. These through holes 2 are formed at intervals that can be aligned with the plurality of through holes 14 formed in the structure 12 described above.

The L-shaped connector 1 of the present invention may be formed by bending a flat plate of metal or ceramic at a right angle to have a U-shaped cross-sectional shape, or may be formed by welding two flat plates of metal or ceramic to have an L-shaped cross-sectional shape, or may be formed by pouring molten metal into a mold and molding it to have an L-shaped cross-sectional shape. In any case, it is considered to be included in the L-shaped connector described in the claims of this application.

Figure 5 shows one embodiment of the U-shaped connector 4 of the present invention. On two opposing faces, a plurality of through holes 5 are formed in one or more rows at equal intervals (the center-to-center distance between adjacent holes is, for example, 50 mm). These through holes 5 are formed at intervals that can be aligned with the plurality of through holes 14 formed in the structure 12 described above.

Figure 6 shows another embodiment of the U-shaped connector 6 of the present invention. A plurality of through holes 8 are formed in one or more rows at equal intervals (for example, 50 mm center-to-center distance between adjacent holes) on the intermediate surface 40 connecting two opposing surfaces. In still other embodiments, a plurality of through holes 8 may be formed on only another surface of the U-shaped connector 4, or through holes 8 may be formed on three surfaces. These through holes 8 are also formed at intervals that can be aligned with the plurality of through holes 14 formed in the structure 12 described above.

The U-shaped connectors 4 and 6 of the present invention may be made by bending a metal or ceramic plate at two right angles to give it a U-shaped cross-sectional shape, or by welding three metal or ceramic plates together to give it a U-shaped cross-sectional shape, or by pouring molten metal into a mold and molding it to give it a U-shaped cross-sectional shape. In any case, they are considered to be included in the U-shaped connectors described in the claims of this application.

In the embodiment shown in FIG. 7, an H-shaped steel 22 is attached to the end surface (top surface) 16 of the structure 12 via two L-shaped connectors 1 of the present invention. In detail, a number of bolts 26 are passed through aligned through holes and fixed using nuts 28 so that the bent portion 20 of the L-shaped connector 1 is positioned along the top edge of one side surface 18 of the structure 12. The clamp facing surface 34 of the H-shaped steel 22 and the clamp facing surface 32 on the back side of the shaped steel abutment surface 30 of each L-shaped connector 1 are each fastened by a clamp 24.

In the embodiment shown in FIG. 8, one channel steel 36 is attached to the side surface 18 of the structure 12 via the L-shaped connector 1 of the present invention. In detail, a number of bolts 26 are passed through aligned through holes and fixed using nuts 28 (not shown) so that the bent portion 20 of the L-shaped connector 1 is positioned along the side surface 18 of the structure 12. A clamp 24 is then clamped between the clamp facing surface 34 of the channel steel 36 abutting against the L-shaped connector 1 and the clamp facing surface 32 on the back side of the shape steel abutment surface 30 of the L-shaped connector 1.

In the temporary structure construction set of the present invention, as shown in FIG. 8, when the side surfaces 18 of two structures 12 are arranged flush with each other with no gaps, multiple through holes 14 are aligned at equal intervals (for example, 50 mm center-to-center distance between adjacent holes) across these structures 12. In other words, when the center-to-center distance between adjacent holes is, for example, 50 mm, the center of the through holes 14 formed in each structure 12 is 25 mm inward from the position of the outer edge that forms the structure 12. This allows the multiple through holes 2 of the L-shaped connector 1 to be aligned with the multiple through holes 14 of the two connected structures 18, as shown in FIG. 8.

In the embodiment shown in FIG. 9, when two structures 12 are arranged horizontally to form an acute angle, these structures 12 are connected via four L-shaped connectors 1 (the two L-shaped connectors 1 are hidden by the structures 12 in FIG. 9). In detail, a plurality of bolts 26 are passed through aligned through holes and fixed using nuts 28 so that the bent portion 20 of the L-shaped connector 1 is arranged along one bottom side of the upper structure 12 or one top side of the lower structure 12. Then, the clamp facing surface 32 of each L-shaped connector 1 is respectively tightened by the clamp 24. In this way, the L-shaped connector 1 can also be used to connect structures 12 having multiple holes.

In the embodiment shown in FIG. 10, an equal-leg angle steel (L-shaped steel) 38 is attached diagonally via two L-shaped connectors 1 so as to form an acute angle with respect to one side surface 18 of the horizontally extending structure 12. In detail, a number of bolts 26 are passed through aligned through holes and fixed using nuts 28 so that the bent portion 20 (not shown) of each L-shaped connector 1 is arranged along one side of the structure 12. The clamp-facing surface 34 of the equal-leg angle steel 38 and the clamp-facing surface 32 on the back side of the steel-shaped steel abutment surface 30 of each L-shaped connector 1 are each fastened by a clamp 24.

In the embodiment shown in FIG. 11, an H-shaped steel 22 is attached to the end surface (top surface) 16 of two structures 12 via two L-shaped connectors 1 and one U-shaped connector 4. In detail, a plurality of bolts 26 are passed through aligned through holes and fixed using nuts 28 so that the bent portion 20 of the two L-shaped connectors 1 is arranged along the top side of the structure 12. On the other hand, a plurality of bolts 26 are passed through aligned through holes and fixed using nuts 28 so that the first bent portion 42a of the U-shaped connector 4 is arranged along the top side of one side 18 of the first structure 12, and the second bent portion 42b of the U-shaped connector 4 is arranged along the top side of one side 18 of the second structure 12. Then, the clamp facing surface 34 of the H-shaped steel 22 and the clamp facing surfaces 32, 44 on the back side of each connector 1, 4 are respectively tightened by clamps 24.

In the embodiment shown in FIG. 12, an H-shaped steel 22 is attached to the end surface (top surface) 16 of the structure 12 via two L-shaped connectors 1. Furthermore, two equal-leg angle steels 46a, 46b are attached to one side surface 18 of the structure 12 via one U-shaped connector 6. In detail, a plurality of bolts 26 are passed through aligned through holes and fixed using nuts 28 so that the bent portions 20 of the two L-shaped connectors 1 are positioned along the top side of the structure 12. On the other hand, a plurality of bolts 26 are passed through aligned through holes and fixed using nuts 28 so that the intermediate surface 40 of the U-shaped connector 6 is positioned along one side surface 18 of the structure 12. The clamp-facing surface 34 of the H-shaped steel 22 and the clamp-facing surfaces 54 of the equal-leg angle steels 46a, 46b, and the clamp-facing surfaces 32, 52 of the connectors 1, 6 are respectively fastened by clamps 24.

As described above, in the temporary structure construction set of the present invention, the multiple through holes formed in each of the L-shaped connector 1, the U-shaped connectors 4 and 6, and the structure 12 are formed at equal intervals, and further, when the side surfaces 18 of the multiple structures 12 are arranged flush with each other without any gaps, the multiple through holes 14 are arranged at equal intervals (the center-to-center distance between adjacent holes is, for example, 50 mm) across the multiple structures. In other words, the present invention makes it possible to connect the L-shaped connector 1 or the U-shaped connector 6 in which multiple holes are formed to all sides of the structure 12 in which multiple holes are formed.
