How to Build a Temporary Structure

Abstract

To provide a method for constructing a temporary structure.SOLUTION: A plurality of bolts 26, inserted through aligned through-holes, are secured using nuts so that a folded portion 20 of an L-shaped joint 1 is positioned along a side 18 of a structure 12. Then, a clamp 24 is clamped between a clamp-facing surface 34 of a groove steel 36 that is in contact with the L-shaped joint 1 and a clamp-facing surface 32 on the back side of the shaped steel contact surface 30 of the L-shaped joint 1. When the sides 18 of the two structures 12 are placed flush with each other without gaps, a plurality of through-holes are equally spaced (e.g., 50 mm between centers of adjacent holes) across these structures 12. That is, when a distance between centers of adjacent holes is 50 mm, the centers of the through-holes in each of the structures 12 are located 25 mm inward from a position of an outer edge forming the structure 12. This allows the through-holes of the L-shaped joint 1 to be aligned with respect to the multiple through-holes of the two connected structures 18.SELECTED DRAWING: Figure 8

Description

[Technical field]

[0001] The present invention relates to a connector and a temporary structure construction set used for constructing various temporary structures at construction sites and the like, and to a method for constructing a temporary structure. [Background technology]

[0002] When heavy objects are to be brought in to a construction site or the like, temporary structures are sometimes constructed using materials such as various shapes of shaped steel (channel steel, L-shaped steel, etc.), support structures, brackets (L-shaped mounting fixtures), etc. Such temporary structures can be constructed in various ways depending on the conditions of the site where the various items are to be brought in, the size and weight of the items, etc.

[0003] Fig. 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. As shown in Fig. 1, connectors 64 of various shapes may be used to connect shaped steel such as channel steel 70 while preventing the structure from buckling.

[0004] Fig. 2 is an enlarged view of the part surrounded by the two-dot chain line in Fig. 1. According to the conventional technology, when fixing the H-shaped steel 62 to the structure 60 via a conventional bracket 64 using a bolt 66 and a nut 68 in order to connect a shaped steel such as an H-shaped steel 62 to the structure 60, it is necessary to drill new bolt holes in the structure 60, the H-shaped steel 62, and the bracket 64 each time depending on the size of the work site, etc., which may hasten the wear and tear of each material. Alternatively, when the structure or shaped steel is a rental product, it is sometimes necessary to connect them using only clamps because it is not possible to drill bolt holes in those materials.

[0017] The L-shaped connector, the U-shaped connector, the temporary structure construction set, and the method for fixing shaped steel to a structure of the present invention will be described below with reference to the accompanying Figs. 3 to 12.

[0018] Fig. 3 shows an example of a structure 12 formed from a plate-like metal, hard ceramic, or the like. As shown in Fig. 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 plurality of through holes 2 may be formed so that the center-to-center distance is other than 50 mm, but even in that case, the plurality of through holes 2 are formed so that they are equally spaced apart with the center-to-center distance other than 50 mm.

[0019] As shown in FIG. 3, the structure 12 has an outer shape of a polygonal prism (for example, a rectangular parallelepiped), and has a hollow portion penetrating each surface 18 of the polygonal prism. In another embodiment, the structure 12 is an H-shaped column 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 column. In yet another embodiment, the structure 12 is a U-shaped column 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 column. The L-shaped connector 1 and U-shaped connectors 4 and 6 as connectors for connecting existing shaped steel to such a structure 12 will be described below.

[0020] 4 shows an L-shaped connector 1 of the present invention. In one embodiment, a plurality of through holes 2 are formed in one or more rows at equal intervals (the center-to-center distance between adjacent holes is, for example, 50 mm) on one surface of the L-shaped connector 1. Furthermore, a plurality of through holes 2 may also be formed in one or more rows at equal intervals on a surface perpendicular to the one surface. 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.

[0021] The L-shaped connector 1 of the present invention may be formed by bending a metal or ceramic plate at a right angle to have a U-shaped cross section, may be formed by welding two metal or ceramic plates to have an L-shaped cross section, or may be formed by pouring molten metal into a mold and molding to have an L-shaped cross section. In any case, it is considered to be included in the L-shaped connector described in the claims of this application.

[0022] 5 shows one embodiment of the U-shaped connector 4 of the present invention. A plurality of through holes 5 are formed in one or more rows on two opposing surfaces 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 allow them to align with the plurality of through holes 14 formed in the structure 12 described above.

[0023] 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 an 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.

[0024] The U-shaped connectors 4 and 6 of the present invention may be formed by bending a metal or ceramic plate at right angles at two points to have a U-shaped cross-sectional shape, or may be formed by welding three metal or ceramic plates to have a U-shaped cross-sectional shape, or may be formed by pouring molten metal into a mold and molding to have a U-shaped cross-sectional shape. In any case, the U-shaped connectors described in the claims of this application are included in the scope of the present application.

[0025] 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 plurality of bolts 26 passed through aligned through holes are fixed using nuts 28 so that the bent portion 20 of the L-shaped connector 1 is disposed along the top edge of one side surface 18 of the structure 12. Then, 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.

[0026] 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. More specifically, a plurality of bolts 26 passed through aligned through holes are fixed using nuts 28 (not shown) so that the bent portion 20 of the L-shaped connector 1 is arranged along the side surface 18 of the structure 12. Then, a clamp 24 is 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.

[0027] In the temporary structure construction set of the present invention, when the side surfaces 18 of two structures 12 are arranged flush with each other without any gaps, as shown in Fig. 8, a plurality of through holes 14 are arranged at equal intervals (the center-to-center distance between adjacent holes is, for example, 50 mm) across these structures 12. In other words, when the center-to-center distance between adjacent holes is, for example, 50 mm, the position of the center of the through holes 14 formed in each structure 12 is 25 mm inward from the position of the outer side that forms the structure 12. This allows the plurality of through holes 2 of the L-shaped connector 1 to be aligned with the plurality of through holes 14 of the two connected structures 18, as shown in Fig. 8.

[0028] 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 (two L-shaped connectors 1 are hidden by the structures 12 in Fig. 9). In detail, a plurality of bolts 26 inserted through aligned through holes are 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 a plurality of holes to each other.

[0029] In the embodiment shown in Fig. 10, an equal-leg angle iron (L-shaped steel) 38 is attached obliquely 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. More specifically, a plurality of bolts 26 inserted through aligned through holes are fixed using nuts 28 so that the bent portion 20 (not shown) of each L-shaped connector 1 is disposed along one side surface of the structure 12. Then, the clamp-facing surface 34 of the equal-leg angle iron 38 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.

[0030] 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. Meanwhile, 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 fastened by clamps 24.

[0031] 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 arranged along the top side of the structure 12. Meanwhile, a plurality of bolts 26 are passed through aligned through holes and fixed using nuts 28 so that the middle surface 40 of the U-shaped connector 6 is arranged along one side surface 18 of the structure 12. Then, 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.

[0032] 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, 6, and the structures 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 these multiple structures. That is, 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 surfaces of the structures 12 in which multiple holes are formed.
