Description

[Detailed explanation of the invention] This invention uses multiple steel sections (H, groove, mountain, and T sections, etc.) and pipes or bars (round bars, reinforcing bars, etc.) that have threads in some or all of them. This invention relates to the assembly structure of a reinforcing cage unit when a plurality of reinforcing cage units consisting of the above are arranged while being connected in the vertical and horizontal directions, and crushed stone or concrete blocks are packed therein to construct an embankment such as a sand control or embankment.

Conventionally, in this type of embankment, the reinforcing cage units were connected to each other by bolts.
Because they were connected with nuts, assembly was troublesome and the strength was weak.

This invention was developed in order to solve the above-mentioned conventional problems, and as an example, a plurality of reinforcing bar cage units made of a threaded bar having a threaded part and a plurality of H-beams are used. When constructing embankments such as erosion control or embankments by placing crushed stones and concrete blocks in a connected manner in the vertical and horizontal directions, a connecting plate is placed across the flange end of the H-shaped steel, and the A communicating through-hole is formed in the connecting plate and the flange end, and the threaded bar of the reinforcing bar cage unit is passed through the through hole, and a fixing nut is screwed into the penetrating portion to connect the reinforcing bar cages adjacent to each other in the longitudinal direction of the embankment. Reinforcement cage units that are adjacent to each other in the vertical direction of the embankment can be connected to each other by connecting the units, passing the threaded bar of the reinforcing bar cage unit through the through hole formed in the flange of the H-shaped steel, and screwing a fixing nut into the penetrating part. are connected by upper and lower flanges of H-beam steel, and if necessary, reinforcing bar cage units are connected with threaded bars in the thickness direction of the embankment, and if the embankment is to be thickened, it is formed into a web of H-beam steel. The reinforcing bar cage units adjacent to each other in the thickness direction of the embankment are connected to each other by passing the screw holes of the reinforcing bar cage units through the through holes and screwing fixing nuts into the through holes.

In addition, steel pipes that maintain the spacing between the H-beams are inserted through the threaded holes to simplify the assembly work of the reinforcing bar cage units and increase the connection strength between the reinforcing bar cage units. and a through hole formed in the connection plate (hereinafter referred to as a screw bar through hole).

) is an attempt to make the entire reinforcing bar cage unit enclosing by making the holes long or loose so that the screws can move freely, so that it can be freely adapted to the shape of the ground at the embankment construction site.

Incidentally, although a screwdriver is described as one example,
There is no particular problem in use as long as a threaded portion is provided at the end of a pipe of a predetermined length or a bar such as a reinforcing bar or a round bar or where necessary.

This invention will be explained below with reference to an illustrated embodiment.

This invention consists of the above-mentioned structure, and the following effects can be expected.

■ The reinforcing bar cage unit is composed of multiple H-shaped steels and threaded bars, and a steel pipe that maintains the spacing between the H-shaped steels is attached to the threaded bar by inserting the threaded bar into the steel pipe, and the threaded bar is fixed to the H-shaped steel. Since they are connected with nuts, they have great strength and are extremely easy to assemble.

■ The reinforcing bar cage units are connected to each other not by bolts or nuts, but by the screw bars and fixing nuts, the threaded bars, fixing nuts, and connection plates, which are the components of the reinforcing bar cage units, so the connection strength between the reinforcing bar cage units is increased. It is extremely high, and the work of connecting the reinforcing bar cage units to each other can be easily performed in parallel with the assembly work of the reinforcing bar cage units.

As a result, it is possible to easily construct a necessary size of erosion control, embankment, etc. by sequentially connecting and arranging the reinforcing bar cage units in the longitudinal direction, vertical direction, and width direction.

■ By forming the bolt insertion holes of the H-shaped steel and connecting plate into loose holes or long holes that are larger than the diameter of the threaded bar, the entire reinforcing bar cage unit is given flexibility, so when assembling the reinforcing bar cage unit, it can be easily used at the embankment construction site. It is possible to freely deal with the shape of the ground.
