Description

[Detailed Description of the Invention] The present invention relates to a joining structure for joining wires used for joining intersecting wires in mountain shoring and the like.

Conventionally, as shown in FIG. 1, U-bolts 5 are usually used to connect the intersecting threads 1, 1' to each other.

However, the U-bolt 5 had a problem in that it did not have sufficient bending strength and was easily deformed.

The present invention solves the above-mentioned conventional problems, and the joint structure for rice cakes of the present invention (hereinafter referred to as the joint structure of the present invention) will be described below with reference to embodiments shown in the drawings.

FIG. 2 shows a joining tool used in the joining structure of the present invention, and the joining tool 7 has a main body 8 formed of an angle steel material into a substantially U-shape.
has.

A bottom plate 9 having a hole 10 is fixed to each of the pair of ends of the main body 8 at right angles to the main body 8 by welding or the like.

Further, two holes 11, 11 are provided on the front side of the upper side of the main body 8.

FIG. 3 shows the reinforcing material 12 used in the joint structure of the present invention,
The reinforcing member 12 is a plate-like body having bent pieces at both ends and two holes 13, 13 provided in each of the bent pieces.

The joining structure of the present invention is assembled using the above-mentioned joining tool 7 and reinforcing material 12, and this will be explained below along with the assembly method based on FIG. 4.

In other words, H-shaped steel threads 1 and 1' are provided to intersect with each other, and at the intersection, a pair of joints 7.7 are attached to the upper thread 1 with their ends facing downward.

Furthermore, a pair of joint tools 7, 7 are attached to the lower wire 1' at the intersection.
is attached with the end facing upward.

On the bottom plates 9, 9 at the left and right ends of the pair of connectors 7, 7 attached to the upper basket 1, there are attached the opposite ends of the pair of connectors 7, 7 attached to the lower bowl 1'. Bolts 20 to the bottom plates 9, 9 of the
, 20 . . . A reinforcing member 12 is attached between the upper sides of the joining tools 7, 7 attached to the upper wire 1.

The reinforcing material 12 has holes 11 in the connector 7 and holes 13 in the reinforcing material 12.
The joint tools 7, 7 are connected by bolts 20, 20... that pass through the
fixed between.

Similarly, a reinforcing material 12 is also fixed between the joining tools 7, 7 attached to the lower katana 1.

The operation of the joint structure of the present invention shown in the above embodiments will be explained next.

In other words, the force acting between the wires 1 and 1' is the force that tries to separate the joining tools 7, 7, which are joined above and below, the distance between the upper joining tools 7, 7, or the lower joining tool. 7. It appears as a force that tries to shift the distance between 7.

The former force is borne as a tensile stress on the sides of the joints 7, 7..., and the latter force is borne as a tensile stress or compressive stress on the reinforcing members 12, 12 to prevent the wires 1, 1' from slipping. be done.

In the above embodiment, the reinforcing member 12 was fixed between the upper sides of the joints 7.7, but it may also be fixed between the sides of the joints 7, 7.

The scallop joint structure of the present invention has the following effects in terms of the above-mentioned configuration, assembly method, and operation.

(1) The joining structure of the ropes of the present invention has the structure described in the claims of the utility model registration, and in particular, since the joints made of angle steel are used, the ropes can be firmly joined to each other.

(2) The beam joint structure of the present invention has the same structure as above, and because it uses joints made of angle steel, it does not easily deform, and as a result, the constituent members can be disassembled and reused after use. I can do it.

(3) The beam joining structure of the present invention has the same structure as above, and in particular, the beams are joined with sufficient strength due to the use of reinforcing materials.
