Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to a method of manufacturing a building wall.

Technical background of the invention 1 For example, in various plants such as nuclear power plants, embedded hardware is used to support equipment, piping trays, ducts, various frames, etc. It is installed and embedded in the wall in advance.

Fig. 1 shows such embedded metal fittings, which include, for example, a 25 cm square plate 1 and this plate 1.
It consists of stud bolts 2 erected from each corner of the plate 1, and nail holes 3 drilled in the two corners of the plate 1.

When installing such embedded metal fittings on the building wall, reinforcing steel 4
After installation, insert stud bolt 2 at the predetermined position.
A method of fastening the plate 1 to a reinforcing bar 4 with wire or the like, or a method of fixing the plate 1 to a concrete formwork with nails using the nail holes 3 drilled in the plate 1, etc. are used.

[Problems with the background art] However, when such a method is used, for example, thousands of embedded metal objects must be manually installed one by one, and the accuracy of the installation is very poor (and the mounting accuracy is very poor). Since the metal fittings are temporarily fixed with nails, wire, etc., there was a problem that the setting position was thick (shifted) and buried in the concrete surface due to the pressure during concrete pouring. Hole-in anchors, etc. had to be used when adding embedded metal fittings and when modifying equipment after plant operation.

[Object of the invention] The present invention has been made in response to such conventional circumstances,
The purpose of installing embedded metal fittings is to improve accuracy, shorten the construction period, and provide a manufacturing method for building walls that can be supported from anywhere.

[Summary of the Invention 1 In other words, the present invention includes a reinforcing bar placement step in which reinforcing bars are placed on the foundation of a building wall, and after this reinforcing bar placement step, a plurality of windows are placed between the reinforcing bars on at least one side and a plurality of windows are placed on the concrete pouring side. a formwork installation step of installing a formwork having stud bolts;
A connecting step of connecting the formwork using connecting members at regular intervals using the window, a window closing step of closing the window with a cover plate after this connecting step, and after this window closing step the above-mentioned This method of manufacturing a building wall is characterized by comprising a concrete pouring step of pouring concrete between formworks.

[Embodiment 1 of the Invention] The details of the present invention will be described below with reference to the drawings.

According to the method for manufacturing a building wall according to an embodiment of the present invention, first, a reinforcing bar placement process is performed in which reinforcing bars 4 are placed on the foundation of the building wall, and after this reinforcing bar placement process, the reinforcing bars 4 are sandwiched and molded. A formwork installation step is performed to install the frame.

The formwork used in this formwork installation process, as shown in FIG. 1. A large number of stud bolts 7 arranged on the pouring side and each window 5
It is formed from bolt holes 8 arranged at the four corners of the
The size of the cross-shaped iron plate 6 is approximately the same as the wall surface.

After this formwork installation process, a connecting process is performed in which the formworks described above are connected at regular intervals.

3- In other words, this connection process uses a window 5 formed in a cross-shaped iron plate 6, as shown in FIG. This is done by connecting the connected connecting members 9 that have been connected together by welding or the like.

After this connection process, a window closing process is performed to close the windows 5 formed in the cross-shaped iron plates 6.

That is, this window closing process is carried out by attaching a cover plate 10 cut into a certain shape in advance to the window 5 of the cross-shaped iron plate 6 with bolts 11, as shown in FIG. It is screwed into the bolt hole 8 of the cross-shaped iron plate 6 through the hole.

After this window closing step, a concrete pouring step is performed in which concrete≧1.12 is poured between the formworks.

Figures 4 to 6 show the building wall after this concrete pouring process is completed, Figure 4 is an external view showing a part of it in cross section, and Figures 5 and 6 are respectively v in the diagram
-V line and Vl-Vl line.

4- According to the manufacturing method for building walls as described above, the embedded hardware is directly used as the formwork, so there is no need to manually attach the embedded hardware to the building wall as in the past, improving work efficiency. At the same time, it is possible to improve the accuracy of the mounting of the embedded metal fittings.

In addition, supports for equipment, piping, trays, ducts, and various types of mounts can be taken from any position on the wall.
Addition of equipment piping, etc. and changes in layout can be easily handled.

[Effects of the Invention] As described above, according to the method for manufacturing a building wall of the present invention,
Since it is no longer necessary to fix embedded hardware one by one to reinforcing bars, etc., the manufacturing period for building walls can be significantly reduced.

Moreover, the positional accuracy of the embedded metal object can be greatly improved.

In the embodiment described above, an example was described in which the cross-shaped iron plate was made almost the same size as the wall surface, but it goes without saying that it may be used by appropriately dividing it.
