Description

[Detailed description of the invention] This invention is based on the upper facing plates 2, 2 of the U-shaped vertical groove metal fitting 1.
A pair of screw rods 3, 3 are provided which are screwed into the grooves of the metal fitting 1 from the outside in opposite directions, respectively, and a Λ-shaped annular blade 4 is formed at the opposing end surfaces of both screw rods 3, 3, respectively. A U-shaped groove 6 is formed in the middle of the upper edge of the vertical plate 5 provided on the outer side of the lower part of the metal fitting 1, and the tip of the upper edge is screwed into the inside of the U-shaped groove 6 from the outer side and toward the upper part of the metal fitting 1. A screw rod 7 is provided, and a tip Λ-shaped annular blade 8 is formed on the tip surface of the screw rod 7 that is threaded inside the U-shaped groove.
The present invention relates to a joining fitting for a temporary structure in which an end surface 9 facing the top end surface is supported inside the U-shaped groove 6, and a Λ-shaped annular blade 8 is formed on the end surface 9. It is preferable that the center lines a and b of the screw rods 3 and 3, the screw rods 7 and the end faces 9 are in the same plane, and the center lines a and a of the screw rods 3 and 3 are common. The center line a and the center line b of the threaded rod 7 and the end face 9 are perpendicular to each other as shown in FIG. 3, or the common center line a and b are the same as shown in FIG. It can be placed on top. Of course, the center line a coincides with the center line of the Λ-shaped annular blade 4, and the center line b coincides with the center line of the Λ-shaped annular blade 4.
It is preferable that the shape coincides with the center line of the annular blades 8, 8, but there is no problem even if there is a slight error. The end surface 9 is the third
As shown in the figure, the common center line a is on the back side of the metal fitting 1.
It may be the head end face of the bolt 10 fixed perpendicularly to the bolt 10, or it may be the head end face of one of the screw rods 3 of a pair of screw rods 3, 3 as shown in FIGS. 7 and 8. No problem. The metal fitting 1 has a downwardly extending portion 11, and the vertical plate 5 is provided on the outside of the portion 11.
is fixed, and the direction of the vertical plate 5 is perpendicular to the center line a (FIG. 4) or parallel to the common center lines a and b (FIG. 8). In the figure, 12 indicates a female screw into which the threaded rod 7 is screwed into the U-shaped groove, and 13 indicates a Λ-shaped conical blade provided at the center of the Λ-shaped annular blades 4 and 8.

Therefore, as shown in FIGS. 1, 3, 5, and 7, an upright H is provided inside the vertical groove 14 of the metal fitting 1.
Insert the flange part 16 of the shaped steel column 15 and
is in contact with the bottom surface of the vertical groove 14, and a pair of screw rods 3, 3
The Λ-shaped annular blades 4, 4 and the central Λ
The metal fitting 1 can be fixed to the flange portion 16 by biting the conical blades 13, 13 into both side surfaces of the flange portion 16. In that state, the U-shaped groove 6
One side of the angle iron 17 is inserted into the inside of the U-shaped groove, and the threaded rod 7 screwed inside the U-shaped groove is rotated to advance it toward one side of the angle iron 17, and the same is inserted between the screw rod 7 and the end face 9. The angle iron 17 can be fixed to the metal fitting 1 by pressing the angle iron 17 and causing the Λ-shaped annular blades 8, 8 and the central Λ-shaped conical blade 13 to bite into both sides of the angle iron 17. The weight of the angle bar 17 is supported by the flange portion 16 via the vertical plate 5 and the downwardly extending portion 11 of the metal fitting 1. The angle iron 17 can be passed laterally or diagonally across a plurality of H-shaped steel columns 15, 15 and fixed as described above to form a temporary framework or temporary structure such as a dump truck approach road.

Conventionally, the cross members and diagonal members made of angle iron 17 were welded or bolted to the H-shaped steel columns 15, 15, which required time to assemble and dismantle, and had defects that made it difficult to prevent damage due to material cutting, etc.

This proposal was made in view of the above defects, and
Since this project is constructed as described above, H-beam steel support 1
5 and 15, the cross members and diagonal members made of angle iron 17 can be very easily fixed without welding or bolts, etc., and it is possible to prevent damage due to cutting of materials, etc. without requiring time for assembling and dismantling the temporary structure. There are benefits.
