DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a concrete panel construction method for constructing a building by joining concrete panels of standard specifications.

[Conventional technology]

Conventionally, in the concrete panel construction method using concrete panels of standard dimensions, either (a) the design must be designed so that even if concrete panels of standard dimensions are consecutively installed, there will be no excess or deficiency in the dimensions, or (b) the concrete panels of standard dimensions must be (c) Either prepare concrete panels of special dimensions and connect them to the spaces where concrete panels are too large or too small; Cut to size, connect to connecting reinforcing bars protruding from concrete panels of standard dimensions on both sides, connect reinforcing bars vertically and horizontally to the reinforcing bars, then attach formwork to both sides of the reinforcing bars, and then concrete. The process of constructing a continuous surface by removing the formwork after pouring and curing the concrete. It was due to one of the following. [Problem to be solved by the invention] However, in the conventional example (a) above, the design may not meet the diversifying demands of the client or the effective use of the site. In the conventional example mentioned above, preparing concrete panels with special dimensions eliminates the advantage of the panel construction method, which is rational construction through standardization and cost reduction. In addition, the conventional example (c) above has the problem of increased work at the construction site, which is disadvantageous in terms of construction period and cost. This invention was developed by solving the problems of the prior art described above, and when constructing a wall or floor using concrete panels according to Standard 1, it is possible to easily create a continuous surface even if the dimensions are too large or too small. The purpose of this invention is to provide concrete panels that can be used to construct concrete panels.

[．． Means to solve problem J]

For this reason, the concrete panel construction method according to this invention,
This is a concrete panel construction method in which concrete panels of standard dimensions are joined together to construct a continuous surface of a building. a step of constructing a surface in which concrete panels of standard dimensions with protruding reinforcing bars for connection are joined; a step of combining reinforcing bars in a mesh shape to produce a mesh reinforcement that matches the dimensions of the space; a step of arranging it in the space and connecting it to the connecting reinforcing bars of the standard sized concrete panels on both sides;
A step of attaching home ties to both sides of the mesh reinforcement in contact with concrete panels of standard dimensions on both sides to form a formwork, and pouring concrete into the formwork of the mesh reinforcement portion. The purpose of this invention is to achieve the above-mentioned objective by a process that incorporates an integrated approach and a method characterized by certain features. [Operation] Using the above method, concrete panels of standard dimensions are joined to construct a continuous surface of the building. If the dimensions of the concrete panel are too large or too short and a space is created, that space will be left in place. Furthermore, reinforcing bars for connection protrude from both sides of the space. Next, at a reinforcing steel factory, etc., a mesh bar made by combining reinforcing bars in a mesh shape according to the dimensions of the space is placed in the space, so that it can be used as a reinforcing bar for connecting concrete panels of standard dimensions on both sides. It can be easily joined, and there is no need to assemble reinforcing bars at the construction site. Then, by attaching home ties to both sides of the mesh reinforcement in contact with concrete panels of standard dimensions on both sides, the formwork can be shaped, and concrete can be poured into the formwork of the mesh reinforcement. It is possible to easily construct a continuum.

〔Example〕

Hereinafter, the concrete panel construction method according to the present invention will be explained using examples.

The figure is a perspective view showing a construction process in progress of constructing a wall surface according to an embodiment of the present invention.

In the figure, AI, A2, and A3 are concrete panels with standard size 7 for wall portions, and B is a concrete panel with standard size for wall corners. Normally, concrete panels have connecting reinforcing bars 1 protruding from both sides, and after these reinforcing bars 1 are first connected by welding, etc., formwork is applied to both sides of concrete panels AI and A2, and concrete A continuous wall is constructed by pouring concrete panels and connecting concrete panels.

S is concrete panel AI, A2.
This is a space where the concrete panel dimensions are either too large or too small for the required wall length due to the connection of A3 and B. On both sides of the space S, connecting reinforcing bars 1 protrude from concrete wall panels Al and A2 of standard dimensions. M is a mesh reinforcement that connects the space S. This mesh reinforcement S does not need to be produced at the construction site, but can be manufactured in advance at a factory specializing in reinforcing bars, etc., depending on the dimensions of the space S determined at the design stage. be able to. Then, horizontal reinforcing bars 2 and vertical reinforcing bars 3 connected to the connecting reinforcing bars 1 of concrete panels AI and A2 of standard dimensions are combined to form one mesh-like panel. Of course, reinforcing bars may be combined in a lattice pattern to form a panel. Tl, T2 are home ties, and concrete panels AI, A2 with standard dimensions on both sides are placed on both sides of the mesh reinforcement M.
It is a plate-shaped item that is attached in contact with the mesh bar and forms a frame in the S part of the mesh. If necessary, the surfaces of home ties TI and T2 may be finished and left as they are after pouring concrete into the formwork shaped into the mesh tlfJS portion and curing. Note that the home ties TI, T2 are provided with a plurality of holes 4 for fastening ports that are passed through the home ties TI, T2 on both sides.

Next, each process will be explained. First, the foundation work was done, and on top of the foundation, concrete panels of standard dimensions for walls, Al, A2, A3. Construct the wall using conventional construction methods using concrete panels B with standard dimensions for wall corners. In addition, the wall surface is constructed by leaving the space S created due to the excess or deficiency of the dimensions due to the standard dimensions. Also, concrete panels AI with standard dimensions for walls on both sides of the space S,
A connecting reinforcing bar l protrudes into the space S from A2. The mesh reinforcement M is prepared and placed in the space S. Then, the horizontal reinforcing bars 2 of the mesh bars M and the connecting reinforcing bars 1 of the concrete panels At and A2 of standard dimensions on both sides are connected by welding or the like. And mesh muscle M
By attaching home ties TI and T2 to the concrete wall panels AI and A2 on both sides using the tie port holes 4, etc., connect the concrete to the mesh reinforcement M part.
Form the formwork for pouring. Next, concrete is poured into the formwork formed on the M section of the M section and cured. And if necessary,
Remove home ties Tl and T2. Through the following seven steps, a concrete panel AL. A continuous wall can be constructed using A2, A3 and concrete panels B with standard dimensions for wall corners. In addition, the portion S that is too large or too small due to the concrete panel having standard dimensions can be easily constructed into a continuous wall surface with less work at the construction site. Although the above embodiment shows an example of constructing a wall surface, the concrete panel construction method of the present invention can be similarly applied to constructing a floor surface. In other words, it is possible to construct a continuous floor surface by using concrete panels with standard dimensions for floor surfaces, and connecting them by pouring concrete using mesh bars and home ties for areas where the dimensions are too large or insufficient. [Effects of the Invention] As explained above, according to the present invention, reinforcing bars for connection are protruded from the sides on both sides of the space created by the over/under dimensions of concrete panels of standard dimensions. Construct a surface by joining concrete nocturnals of standard dimensions,
The reinforcing bars are combined into a mesh shape, and a mesh bar that matches the dimensions of the space is manufactured, placed in the space, and connected to the connecting reinforcing bars of the concrete panels of standard dimensions on both sides. Then, on both sides of the mesh reinforcement, in contact with the concrete panel, home ties are attached to form a formwork, which is removed from the process of pouring concrete.
It is possible to provide a concrete panel construction method that can easily construct a continuous surface even if there are excesses or deficiencies in dimensions when constructing walls or floors with concrete panels of standard dimensions. It is possible to create a design that meets the diversifying demands of the client and the effective use of the site, and there is no need to prepare concrete panels with special dimensions. By reducing the amount of work required, the following effects can be achieved: (1) Shortening of the construction period, rational construction, and cost reduction.
