Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to reinforcing bars placed in the ground when constructing slope protection structures, and in particular relates to prefabricated reinforcing bar assemblies.

[Prior art and its issues]

Conventionally, slope protection structures have been developed that are constructed by building formwork in a lattice pattern that extends horizontally and vertically into the ground, placing reinforcing bars within the formwork, and pouring concrete into the formwork. . In recent years, such slope protection structures have begun to be constructed which have especially strong structures with a large amount of reinforcing steel.

In construction work involving a large amount of reinforcing bars, it is extremely difficult to arrange the reinforcing bars accurately as designed on uneven slopes.

This invention was made in order to solve the above-mentioned problems, and relates to a reinforcing bar assembly that can accurately and easily arrange reinforcing bars in the ground.

[Means to solve the problem]

The reinforcing bar assembly according to this invention is prefabricated at a factory and transported to the site for installation.

At least two upper end reinforcements and at least two lower end reinforcements constitute a main reinforcement assembly. The upper end reinforcement and the lower end reinforcement are separated from each other by an appropriate interval and arranged in parallel. The top reinforcement is placed on the top side of the formwork, and the bottom reinforcement is placed on the ground side.The number of reinforcements can be selected as appropriate, but at least two main reinforcements placed on the left and right ends should be used. It is used to construct the main reinforcement assembly.

Two sets of main reinforcement assemblies made up of at least four main reinforcements are assembled in a cross shape by intersecting each other. In this state, fix each main reinforcement at the desired position,
It unifies the whole. For example, a rectangular ring-shaped hoop reinforcement is placed around the outer circumference of the main reinforcement and fixed thereto by welding or the like, and intersecting main reinforcements are fixed to each other by welding or the like. Instead of welding, they may be bound with a binding wire. Further, in order to position each main reinforcement at a predetermined width and height, the distance between each main reinforcement may be maintained and fixed using, for example, spacers arranged in a rectangular shape.

Multiple hoop reinforcements are attached to the main reinforcement assembly that overhangs in all directions. The hoop muscle has a rectangular ring shape or the like, and is placed so as to surround the outer periphery of the main reinforcement assembly. Each hoop muscle is made movable along the main muscle.

[Effect]

Rebar assemblies are delivered to the site, placed at the vertical and horizontal intersections of the slope protection structure, and fixed to anchors driven into the ground. In this state, the positioning of the reinforcing bars in the vertical and horizontal directions has already been completed.

The main reinforcements are placed between the ends of the main reinforcements of the reinforcing bar assembly, which are arranged at appropriate intervals, so that they overlap. The height of the main reinforcing bars can be adjusted to match the main reinforcing bars of the reinforcing bar assembly. The hoop reinforcing bars placed on the reinforcing bar assembly are moved and placed at appropriate intervals in the longitudinal direction of the main reinforcing bars, and fixed with binding wires or the like.

〔Example〕

This invention will be explained in detail below based on an embodiment shown in the drawings.

In the figure, reference numeral 1 denotes a reinforcing bar assembly, which consists of two sets of main reinforcing bars 2, 2. The main reinforcement assembly 2 is a combination of two upper end reinforcements 3, 3 and two lower end reinforcements 4, 4, which are arranged in parallel with each other at appropriate intervals. Two sets of main reinforcement assemblies 2 are crossed with each other,
Assemble in a cross shape.

A rectangular ring-shaped hoop reinforcement 5 is placed around the intersection of the main reinforcement assembly 2, and the hoop reinforcement 5 and each of the main reinforcements 3 and 4 are fixed by welding 6. Further, the main reinforcements 3 and 4 that intersect with each other are fixed by welding 7.

A plurality of rectangular ring-shaped hoop reinforcements 8 are placed around the outer periphery of the main reinforcements 3 and 4 extending in all directions. The hoop reinforcement 8 is not fixed and is made movable along the main reinforcements 3 and 4.

The reinforcing bar assembly 1 as described above is delivered to the site and placed at an appropriate position in the ground. Main bars 3 and 4 of reinforcing bar assembly 1
The ends of the reinforcing bars are overlapped with each other, and the main reinforcing bars 9 are arranged between adjacent reinforcing bar assemblies 1 and 1 to make them continuous. If necessary, the main reinforcement 10 may be arranged between the upper end reinforcements 3, 3 and the lower end reinforcements 4, 4.

The hoop reinforcement 8 is moved in the longitudinal direction of the main reinforcements 3 and 4 of the reinforcing bar assembly 1 or the main reinforcement 9 that overlaps with the main reinforcements 3 and 4. The hoop lines 8 are arranged at appropriate intervals and fixed with binding wires or the like.

In this way, reinforcing bars are arranged in a lattice pattern on the ground using the reinforcing bar assembly 1 and the main reinforcing bars 9. Weir plates 11,
Place 11. As the weir plate 11, in addition to those made of plywood, expanded metal, crimp wire mesh, metal lath, etc. can be widely used.

The slope protection structure is constructed by pouring concrete 12 into the formwork built into the ground as described above.

[Effect of idea]

This invention has the above configuration and can obtain the following effects.

Since it is made by intersecting two sets of main reinforcement assemblies consisting of upper end reinforcement and lower end reinforcement, it is possible to determine the width and height of the main reinforcement by simply placing it on the ground at the site. Muscle work can be done extremely accurately and easily.

Hoop reinforcement can be arranged simply by placing the main reinforcement between the reinforcing bar assemblies and moving and fixing the hoop reinforcement, making the reinforcement work extremely easy.
