Description

[Detailed description of the invention] This invention relates to a guide rail that guides and supports earth retaining shoring panels.

In order to excavate a trench on the soil surface, bury a pipe, and perform backfilling work, it is necessary to retain earth on the sides of the excavated trench.

In this case, earth retaining panels are guided and supported by guide rails erected on the sides of the trench, and the space between the opposing panels is supported by rod-shaped supports.

The guide rails used here require great strength because they must withstand the impact force of driving into the soil, as well as pressure from the top and loads transmitted from the panels.In addition, from the viewpoint of reliability, the structure is We want it to be as simple as possible;
Furthermore, it must be easy to handle and durable for repeated use.

Traditionally used guide rails have a complicated structure,
The materials used are relatively large, and the above requirements have not been fully met.

This invention was made in view of the above circumstances, and it improves the shortcomings of the conventional technology and provides a guide for earth retaining equipment that is simple in structure, highly reliable, has high strength, and is easy to handle. The purpose is to provide rails.

Corresponding to this purpose, the guide rail for earth retaining devices of the invention has a first reinforcing member located over the entire length of the guide rail and having an H-shaped cross section consisting of a web and flanges at both ends of this web. and a channel-shaped cross section consisting of a web and flanges at opposite ends of the web;
a pair of second reinforcing members fixed to the first reinforcing member from the outside of the flanges of the reinforcing members, and the tips of the flanges of the pair of second reinforcing members face each other at a predetermined interval. It is characterized in that it is configured such that the side end portion of the earth retaining panel can be accommodated between the first reinforcing member and the pair of second reinforcing members.

The details of this invention will be explained below with reference to the drawings showing one embodiment.

In FIGS. 1, 2, and 3, reference numeral 1 denotes a guide rail, which guides and supports the end of the retaining panel 2. As shown in FIG.

The guide rail 1 is provided with a first reinforcement 3.

The first stiffener 3 has an H-shaped cross-section from the web 4 and the flanges 5, 5' at each end of the web 4 and is located over the entire length of the guide rail 1.

This first reinforcing member 3 is made of, for example, H-beam steel.

A pair of second reinforcing members 6, 6' are fixed to the outside of the flanges 5, 5' of the first reinforcing member 3.

The second reinforcing members 6, 6' are made of, for example, channel steel, and have flanges 8, 8' rising up from the web 7 and both ends of the web 7.
It has a groove-shaped cross section consisting of , and is located over the entire length of the guide rail 1 .

Flange 8 and flange 8 on the second reinforcement 6, 6'
are opposed to each other with the required spacing necessary to receive the end of panel 2, and flange 8' and flange 8' are similarly spaced apart as necessary to receive the end of the other panel. They face each other with a distance of .

A bracket 11 is fixed to the outer surface of the second reinforcing member 6 to be connected to the tip of a support rod 9 for connecting guide rails located opposite to each other on both sides of the groove to be excavated. A safety cable holder 12 to which a cable (not shown) is tied is fixed.

In the guide rail configured in this way, the web 4.7 of the first reinforcement 3 has a flange 5, 5' and the flanges 8, 8 or 8', 8' of the second reinforcement 6, 6'.
The side edges of the panel 2 are received in the gap surrounded by the space to support and guide the panel 2.

The guide rail 1 can be constructed from a combination of H-shaped steel and channel steel, and has a high strength against bending etc. compared to the amount of material used, and has a simple structure, and is therefore easy to clean. It is easy and easy to handle for repeated use.
