Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is directed to the construction of reinforced concrete structures such as walls and floors of basements, building foundations, etc., which are constructed by embedding reinforcement bodies such as reinforcing bars inside concrete. It is about the method.

(Prior Art) Conventionally, when constructing reinforced concrete structures such as basement walls, floors, and building foundations, two formwork members are supported at a predetermined interval within a formwork. After arranging vertical and horizontal reinforcement made of reinforcing bars in a grid pattern and tightening the intersections of the vertical and horizontal reinforcement with wires,
Concrete is poured into the formwork to construct a reinforced concrete structure.

(Problems to be Solved by the Invention) In the method for constructing a reinforced concrete structure, it takes time and effort to arrange and tie the vertical and horizontal reinforcements, and it is difficult to arrange and tie the vertical and horizontal reinforcements according to the desired strength. It is complicated and time-consuming because the reinforcement must be arranged by changing the diameter dimension and reinforcement spacing, and furthermore, when concrete is placed in the formwork, There were disadvantages in that the formwork material could not withstand the force of placing concrete and could bend, and the formwork material, vertical reinforcements, horizontal reinforcements, etc. could move due to the force of concrete placement.

(Means for Solving the Problems) The present invention has been made in order to solve the above-mentioned conventional drawbacks, and it is possible to create a formwork material by attaching a mesh-like reinforcement to at least one surface of the plate. Also, locking pieces are formed at both ends and the middle part of the bar material, and formwork supporting pieces are formed near both ends to serve as spacers, and the formwork materials are arranged side by side at intervals. An arbitrary number of mesh-like reinforcement bodies are arranged according to the desired strength in the formwork, and the spacer is installed between the formwork materials, and the locking piece and the formwork support piece of the spacer The method is characterized in that a reinforced concrete structure is constructed by pouring concrete into the formwork while supporting the formwork material and mesh-like reinforcement bodies.

That is, the present invention uses a mesh-like muscle body instead of the conventional vertical and horizontal reinforcements, thereby omitting the labor-intensive reinforcement work of arranging and tightening the vertical and horizontal reinforcements, and making the reinforcement simple and quick. Enables the construction of concrete structures, and furthermore,
It is characterized by preventing the formwork material from bending or moving the formwork material, vertical bars, and horizontal bars (mesh-like bars) when concrete is poured into the formwork. .

(Example) Hereinafter, the present invention will be described in detail based on drawings showing examples.

A mesh-like reinforcement body 3 is attached to at least one side of a plate body 8 such as plywood, a wooden board, an asbestos board, a foamed synthetic resin board, a foamed concrete board, etc. to form a formwork material 1, or a reinforcing bar or other bar material. The spacer 12 is formed by forming locking pieces 10, 10, .
In a formwork 2 formed by arranging the formwork materials 1, 1 in parallel at a predetermined interval, an arbitrary number of mesh-like reinforcement bodies 3, 3, . . . are arranged according to the desired strength. At the same time, the spacer 1 is placed between the formwork materials 1 and 1.

The mesh-like reinforcement body 3 used in the present invention is, for example, as shown in FIG. The intersections 6 of the striations 4 and transverse striations 5 are welded by spot welding to form a plate shape, or as shown in FIG. 2B, the mesh-like reinforcement body 3 shown in FIG. 2A is further reinforced. It refers to a porous plate-shaped reinforcement formed by temporarily installing and welding diagonal reinforcements 7, 7.

In the embodiments shown in FIGS. 1, 4, and 5, a locking piece 10 is provided as a spacer 12 at the middle part of the bar 9 as shown in FIG. 3A.
An example has been illustrated in which a single mesh-like muscle body 3 is disposed within the formwork 2 using individually formed spacers 12, and is supported by the single locking piece 10. As shown in FIG.
0, 10, . . . may be used to arrange and support two, three, or more mesh-like muscle bodies 3, 3, . . . inside the formwork 2. , said FIG. 1. In the embodiments shown in FIGS. 4 and 5, a reinforced concrete structure that is most suitable for the walls of a basement is illustrated, but it goes without saying that basement floors, building foundations, etc. can also be constructed in the same manner as in the embodiments. It is.

In addition, when supporting the formwork materials 1 and 1 and the mesh-shaped muscle body 3 with the spacer 12, for example, as shown in FIGS. 4 and 5, the formwork material 1
A mesh-like muscle body 3 is arranged on the outer surface of the plate body 8 constituting the plate body 8, and the plate body 8 is made up of a plurality of plate bodies 8a, 8b,

(Effects of the Invention) As described above, the present invention provides a formwork material by attaching a mesh-like reinforcement to at least one surface of a plate, and
A locking piece is formed at both ends and an intermediate part of the bar material, and a formwork support piece is formed near both ends to serve as a spacer, and the formwork materials are arranged side by side at intervals in a formwork. An arbitrary number of mesh-like reinforcement bodies are arranged according to the desired strength, and the spacer is installed between the formwork materials, and the locking pieces and formwork support pieces of the spacers hold the formwork material and the mesh together. Since a reinforced concrete structure is constructed by pouring concrete into the formwork while supporting the mesh-like reinforcement bodies, the mesh-like reinforcement bodies act as vertical reinforcements and horizontal reinforcements, and therefore, unlike conventional reinforcements, This eliminates the labor-intensive work of arranging and tightening vertical and horizontal reinforcement, and when constructing a reinforced concrete structure to the desired strength, it is possible to eliminate the diameter dimensions and There is no need to change the reinforcement spacing or arrange reinforcement, and you only need to select and arrange the number of mesh-like reinforcements, so you can easily and quickly construct reinforced concrete structures. , furthermore,
Since the formwork material is formed by attaching a mesh-like reinforcement body to the plate, there is no risk that the formwork material will not be able to withstand the concrete casting force and bend. Since concrete is poured while supporting the formwork material and mesh-like reinforcement with formwork support pieces, there is no risk that the formwork material and mesh-like reinforcement will move when concrete is poured. .
