DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a precast concrete plate for a reinforced concrete wall.

[0002]

2. Description of the Related Art Conventionally, in the case of constructing a reinforced concrete wall, a form is formed by arranging a wall reinforcement, and concrete is cast into the form or constructed, or an outer form is constructed of a precast concrete plate. It was constructed by casting concrete into the formwork formed in the above.

[0003]

However, since all of the above reinforced concrete walls are constructed by forming a formwork, it is time-consuming, and there is a shortage of skilled technicians such as formworkers in recent years. In that case, the workability could not be improved. The present invention has been made in view of these problems, and an object of the present invention is to provide a precast concrete plate for reinforced concrete that can be constructed without requiring a formwork.

[0004]

A precast concrete plate for a reinforced concrete wall according to the present invention for solving the above-mentioned problems is provided by separately forming two precast concrete plates of a predetermined size.
Face the cast concrete plate at a predetermined interval.
Each precast conc.
Multiple trusses can be used to face each other when forming
Arrange the streaks to integrate both precast concrete boards
It is characterized by being connected.

[0005]

The precast concrete plate for the reinforced concrete wall is formed by connecting the precast concrete plates in a state where the long sides are shifted from each other, so that the precast concrete plate for the reinforced concrete wall is also used as a formwork. Therefore, a reinforced concrete wall can be constructed without newly forming a formwork. Also, when constructing a reinforced concrete wall by joining this precast concrete plate for reinforced concrete walls in the horizontal direction, the effective thickness of the reinforced concrete wall must be increased because the joining positions of the precast concrete plates can be shifted from each other. Can be.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. 1 is a cross-sectional view of a reinforced concrete wall of the present invention, FIG. 2 is a vertical cross-sectional view of the same, FIG. 3 is a perspective view of the same, FIGS.
Is a sectional view in use.

A precast concrete plate 1 for a reinforced concrete wall has a truss bar 3 between precast concrete plates 2 which are arranged opposite to each other with their long sides shifted from each other.
And the upper and lower ends of the truss bars 3 are buried in these two precast concrete plates 2 to connect them.

Since these precast concrete plates 2 are connected with their both ends shifted from each other, when the reinforced concrete wall A is constructed by continuous joining in the lateral direction as shown in FIG. The connecting positions are shifted from each other, the connecting bars 4 are arranged, and the post-cast concrete 5 is cast. Thereby, the effective thickness of the reinforced concrete wall A can be set to the thickness (a + b) obtained by adding one of the precast concrete portions b to the post-cast concrete portion a. Further, both ends of the reinforced concrete wall A, that is, columns B
A precast concrete plate 1 for a reinforced concrete wall, in which only the other end of the precast concrete plate 2 is shifted, is used for the joint with the above.

The truss bars 3 include one upper bar 3a and two lower bars 3b arranged at each vertex of an isosceles triangle.
It is formed in a triangular prism shape by the corrugated lattice 3c arranged between the upper and lower muscles 3a, 3b, and three are arranged at appropriate intervals along the longitudinal direction of the precast concrete plate 2. I have.

The truss bars 3 are not limited to the triangular pillars as described above, and one upper bar 3a and a lower bar 3b arranged in parallel as shown in FIG. It may be formed by connecting.

FIG. 6 shows a case where a corner portion of a reinforced concrete wall A is constructed by using a precast concrete plate 1 for a reinforced concrete wall. A connecting bar 4 projecting from both sides is arranged at a joint portion so as to overlap each other. To build.

FIG. 7 shows a case where the reinforced concrete wall A is constructed in a T-shape. The outer wall 6 is constructed of the precast concrete plate 1 for a reinforced concrete wall in which both ends of the precast concrete plate 2 are shifted from each other, and the partition wall 7 is formed. The precast concrete plate 2 is constructed of a precast concrete plate 1 for a reinforced concrete wall in which only the other end is displaced, and a connecting bar 4 is arranged in a T-shape at the joint thereof.

Next, a method for producing the precast concrete plate 1 for a reinforced concrete wall and its use will be described. First, longitudinal and horizontal streaks are arranged in a grid form on a formwork, and truss streaks 3 are arranged on these longitudinal and transverse streaks along the longitudinal direction at appropriate intervals and concrete is poured into the truss. A precast concrete plate 2 in which the streaks 3 project in an inverted V-shape is formed.

Next, the precast concrete plate 2
Are overlapped in a formwork on which the reinforcing steel of the other precast concrete plate 2 is arranged, with the upper reinforcing bar 3a of the truss reinforcing steel 3 being on the lower side and the both ends on the long side being shifted. Then, by casting concrete in the formwork, a precast concrete plate 1 for a reinforced concrete wall in which the precast concrete plates 2 are shifted from each other is formed.

Then, the precast concrete plate 1 for a reinforced concrete wall is continuously erected between the columns B, and a post-cast concrete 5 is poured between the precast concrete plates 2 to construct a reinforced concrete wall A.

[0016]

According to the present invention, by using a precast concrete plate for a reinforced concrete wall also as a formwork, a reinforced concrete wall can be constructed without making a new formwork, so that workability and economy can be improved. .

Two presses each having a predetermined size and formed separately are provided.
Face the cast concrete plate at a predetermined interval.
Each precast conc.
Multiple trusses can be used to face each other when forming
Arrange the streaks to integrate both precast concrete boards
By linked, when linked them laterally to construct a reinforced concrete wall, so wear the junction position placed at a position shifted to one another, it is possible to increase the effective thickness of the reinforced concrete wall. Also formed separately
Two precast concrete boards of a given size
Facing each other at a predetermined interval and shifted from each other
By forming the precast concrete plate for a reinforced concrete wall in a state, it can be used for, for example, a wall at a joint with a column or an end of a partition wall.
