Description

[Detailed description of the invention] This invention relates to a method of constructing walls.

Traditionally, walls were constructed by setting up a temporary frame at a predetermined location and allowing concrete to flow into the temporary frame, but in recent years the use of concrete pressure pump trucks has increased, and concrete pouring from high places has become more popular. Factors that abnormally increase the lateral pressure of the temporary frame are increasing due to the installation and use of vibrators.

Therefore, it is necessary to improve the strength of the temporary frame, and the temporary frame work has the disadvantage of being expensive, accounting for about 60% of the total wall construction. Therefore, in this invention,
The purpose of this project is to provide a method for constructing a wall that can withstand high lateral pressure without using a temporary frame. After arranging them to face each other and screwing the tightening bolts into the nuts to provide a predetermined gap, the tightening bolts are tied and fixed to the pre-installed internal reinforcing bars and stacked one by one, and finally the outer surface of the wall This is a space surrounded by members that allow concrete to flow into the space.

Therefore, since the members that form the outer surface of the wall are connected by tension bolts, they can sufficiently resist lateral pressure, and since the tension bolts are tied to the reinforcing bars, the wall can be constructed without shifting the position and without a temporary frame. Therefore, the above purpose can be achieved.

Embodiments of the second invention will be described below with reference to the drawings.

In the figure, 1 is a member that becomes the outer surface of the wall, for example, it is a concrete product with reinforcing bars 2 arranged inside, and an appropriate shape pattern is applied to the front side 1b, and two nuts 3 are buried on the back side 1b. and one end of it is exposed.

Reference numeral 4 denotes a tightening bolt with threaded portions formed at both ends, one of which is right-handed and the other is left-handed. In addition, the tightening bolt 4 may have threaded portions at both ends and a turnbuckle in the center instead of this left-right tilting bolt.

To show an example of building a wall using the member 1 that becomes the outer surface of the wall and the tightening bolts 4 of the above configuration, first, although not shown, a foundation is made,
On top of that, install the wall reinforcing bars 2, and then the member 1 that will become the outer surface of the wall.
Stack them from the bottom. At this time, the members 1 provided on opposite sides and forming the same wall outer surface are connected by threading the threaded portion of the tightening bolt 4 into the nut 3.

Next, the tightening bolts 4 are bound and fixed to the reinforcing bars 2 with binding wires.

As a result, the position of the member 1, which forms the outer surface of the wall, is fixed. The outer surface of the wall is completed through the following steps.

Note that members 1 serving as the outer surfaces of the wall are also disposed on two sides of the wall, and are bound and fixed to reinforcing bars 2 with binding wires.

Thereafter, concrete is poured into the space surrounded by the member 1, which forms the outer surface of the wall, and is solidified to complete the wall. When this concrete flows in, lateral pressure is applied from the back side to the member 1 that becomes the outer surface of the wall, but since it is connected with the tightening bolt 4, it can counter the lateral pressure and there is no displacement of the member 1 that becomes the outer surface of the wall. It is something that can be preserved.

As described above, according to the present invention, the stacked members serving as the outer surface of the wall function in the same manner as a temporary frame, and the temporary frame can be made unnecessary during wall construction.

The members that will become the outer surface of the wall are connected with the opposing members that will become the outer surface of the wall using tightening bolts and fixed to the reinforcing bars of the wall, so that they can sufficiently resist the lateral pressure applied to the members that will become the outer surface of the wall, and the position No deviation occurs.

This ensures stability in accuracy.

In addition, there is no need for a temporary frame, which has the advantage of lowering the manufacturing cost of the wall.

Furthermore, the member that becomes the wall outer surface becomes the wall outer surface after the wall is completed, and has the advantage that post-processing of the wall surface is unnecessary.

Claims (1)

[Claims] The rectangular wall outer surfaces with decorative surfaces and nuts on the back are arranged so as to face each other, and after screwing a tightening bolt onto the nut and keeping a predetermined gap between the two, the tightening bolt is rearranged. A method of constructing a wall that is characterized in that concrete is first bundled and fixed to internal reinforcing bars, then piled up one after another, and finally poured into a space surrounded by members that will become the outer surface of the wall.
