Description

[Detailed Description of the Invention] The present invention relates to a construction method for buildings such as reinforced or steel-framed small houses and stores, and its purpose is to propose a new construction method that can be easily constructed on-site. It is.

Conventionally, when constructing reinforced steel or steel-framed houses, etc., after setting up the reinforcing bars, etc., a temporary frame was attached and concrete was poured between them, and after the concrete had hardened,
Temporary frames were removed to construct the floors and walls of buildings, but in particular when constructing walls, temporary frames must be installed on both sides of the wall with reinforcing bars etc. In addition to increasing the amount used, a large amount of time was required for the installation work, which led to a rise in production costs.

In addition, when constructing walls, most work is done at heights using scaffolding, which increases the risk of work and makes work extremely difficult.

The present invention aims to solve the above-mentioned problems and to provide a new construction method that can be constructed on-site, and is particularly suitable for constructing small houses, stores, etc.

Hereinafter, the method of constructing a small house, etc. according to the present invention will be explained step by step with reference to the drawings.

Figure 1 shows the state of pouring concrete for the floor. After a temporary frame 2 is installed on the upper end of the foundation 1 and reinforcing bars 3 are set on top of it, ready-mixed concrete is poured to form the concrete floor 4. be.
The floor surface of this concrete floor 4 has holes 5 and stepped portions 6 depending on each building.

Next, the upper surface of the hole 5 is closed with a plate 7, and a temporary frame 8 is provided for the large stepped portion 6 to make the floor surface substantially flat, and then a vinyl sheet 9 is laid on the upper surface of the concrete floor 4.

However, the concrete side walls 10, 10 are laid down on top of this.

At this time, if the area of the concrete floor 4 is narrow, only one side of the concrete side wall 10 is constructed.

A temporary frame 11 is provided on the vinyl sheet 9 to form the periphery of the concrete side wall, and a styrofoam resin plate 13 with a wall thickness equal to the thickness of the side wall 10 is laid in the holes 12 such as entrance holes and window holes. The reinforcing bars 14 are assembled with connecting ends of a required length remaining, and ready-mixed concrete is poured to form the concrete side walls 10, 10. (See FIG. 2) After the concrete side walls 10, 10 are solidified, a vinyl sheet 15 is laid on top thereof, and the remaining side walls 16, 16 are further constructed on top of this.

In this case, a foamed polystyrene resin plate 18 is stuffed into the gap 17 between the two concrete side walls 10, 10 to make the upper surface as flat as possible.

After providing a temporary frame 19 for forming the periphery of the concrete side wall and a temporary frame 21 for forming the window hole 20 on the vinyl sheet 15 and assembling reinforcing bars 22, ready-mixed concrete is poured to a predetermined thickness, and the concrete side wall is 16, 16 is configured in a state where it is laid down. (See Figure 3) Once the concrete side wall at the top level has solidified, a crane is used to remove the concrete side wall 1.
0, 10, 16, 16, remove the vinyl sheets 9, 15, temporary frames 11, 19, 21, etc., and stand them up in a predetermined position.
The ends of the reinforcing bars 3, 14, 22 protruding from the peripheral sides of the walls 0, 16, 16 are welded and fixed, and the concrete side walls 10, 10, 1 are placed on the concrete floor 4.
6, 16 will be erected. (See Figure 4) Concrete floor 4 and each concrete side wall 1
Each corner joint of 0, 10, 16, and 16 is finished by injecting concrete or mortar.

The construction method of the present invention is completed by the above steps, and the concrete side walls 10, 10,
16. If the upper end of 16 is to be covered with a roof or an upper floor is constructed, the floor of the second floor is constructed using the conventional construction method, and then a concrete wall is laid horizontally on top of the floor of the second floor as described above. The second floor is constructed by standing this up in a predetermined position.

As described above, according to the construction method of the present invention, the side walls are sequentially laid down on the floor surface, so there is no need for a temporary frame to restrict the wall surface, and the ready-mixed concrete pours in. It is easy to use and does not cause defects such as poor flow.

Furthermore, since the flatness of the floor surface can be obtained as is when constructing the wall surface, there is no distortion such as warping of the surface, and a flat plate can be obtained with high precision.

Furthermore, since most of the work is done in a fixed position, the present invention has features of high safety and high work efficiency, and the effects of the present invention are extremely large.

Claims (1)

[Claims] 1. In the construction of concrete houses, etc. in which reinforcing bars or steel frames, etc. are arranged within the wall thickness, an intervening material such as a vinyl sheet is placed on the concrete floor surface created by leaving the connected ends of the reinforcing bars or steel frames. A concrete side wall is created by laying a temporary frame for the side wall on top of the temporary frame, leaving the connecting ends of reinforcing bars or steel frames inside the temporary frame, and pouring concrete into the temporary frame and hardening it. After that, an intervening material is further laid on the top surface of this concrete side wall that is lying on its side, and a concrete side wall is constructed using the same method as above. After the required amount of side walls are laminated, these concrete side walls are erected one after another in a predetermined position. A method of constructing a concrete house, characterized in that the connecting ends of the reinforcing bars or steel frames are joined to the concrete floor surface, and the connecting ends of the reinforcing bars or steel frames between the concrete side walls are joined.
