[Industrial use]

The present invention relates to a construction method of a concrete house and the like to build a house or a store by forming a concrete floor and a concrete wall arranged with reinforcing bars or steel frames in a construction site and combining them with each other.

[Prior art]

Conventionally, in the case of constructing concrete buildings with reinforcing bars or steel frames, after assembling the reinforcing bars, the temporary frames are laid and concrete is introduced therebetween to remove the temporary frames after hardening of the concrete. In the case of building a wall, it is necessary to install temporary frames on both sides by inserting reinforcing bars or the like. At the same time, the cost of production increased due to the large amount of working time. In addition, in the case of constructing the wall part, the height of work to assemble the scaffold is the placenta, so the risk of the work was increased, and workability was extremely poor.

[Problems that the invention tries to solve]

In order to solve such a problem, the applicant has devised a construction method that can construct and combine both concrete floors and concrete walls arranged with reinforcing bars or steel frames at the construction site (Japanese Patent Laid-Open No. 3-5452). ).

This method is exposed to the outside from the end surface of reinforcing bars or bones, arranged in the interior of a concrete floor or concrete wall, as described in Japanese Patent Application Laid-Open No. 3-5452. When the concrete floor and the concrete wall and the concrete walls are joined together, the exposed steel bars or steel frames are joined to each other.

In this method, however, the standing method of the concrete wall formed on the concrete floor is not established, and it is impossible to perform the standing work by the force of the worker, and when using a crane, the installation ground of the casein was required. .

In addition, when the concrete floor, the concrete wall and the concrete wall are combined, there is a problem in that when the deviation occurs in the rebar or steel frame exposed from the end surface, their joining becomes difficult.

In addition, if the electric wiring, telephone line, water pipe, gas pipe, etc. arranged on the concrete floor or concrete wall is trivial after the concrete floor or concrete wall is formed, these will be exposed to the floor or wall surface and damage the appearance, Had to be annoying.

The present invention has been made to solve the above problems, while at the construction site to form the concrete floor and concrete wall required as the body structure, while reducing the effort of the worker by performing the standing work of the concrete wall with power as the work efficiency It aims at providing the construction methods, such as concrete houses, which were made to improve.

In addition, the reinforcement of reinforcing steel bars or steel frames arranged inside the concrete floor or concrete wall

The purpose of the present invention is to provide a construction method such as a concrete house where the joining operation can be carried out in a simple manner and the solid bonding strength can be obtained.

In addition, it is an object of the present invention to provide a construction method such as a concrete house with a good appearance by eliminating the effort of laying electric wiring, telephone lines, gas pipes, water pipes, etc. after the concrete floor or concrete wall is formed.

[Means for solving the problem]

In order to achieve the above object, the construction method of the concrete house, etc. of the present invention is to build a concrete floor in which rebar or steel frame is arranged on the foundation formed on the ground and at the same time to install a rail parallel to the base of both sides of the foundation, these rails Beyond the above

It is possible to run a prefabricated door-shaped truss of a required height in a state so that a running block can be freely mounted along a transverse rail provided between the beams of the door-shaped truss, and a spacer is placed on the surface of the concrete floor. Lay out a temporary frame on the upper surface of this separation material to form a concrete wall with rebar or steel frame arranged horizontally, and then install a separation material and temporary frame on this concrete wall surface to After the concrete walls are sequentially formed in the same method, each of the concrete walls is erected sequentially by traction of the chain block so as to be coupled to a predetermined portion of the concrete floor.

In addition, when the concrete floor and the concrete wall are formed, a pair of ant grooves are formed in a required portion adjacent to the concrete floor, the concrete wall, and the concrete wall, and a pair matching each other when the concrete walls are standing up. It is preferable to combine the concrete floor and the concrete wall and the concrete walls by inserting the reinforcing bar into the ant groove of the concrete and simultaneously hardening the concrete.

In the case of the concrete floor and the concrete wall, it is preferable to store pipes such as pipes, water pipes, or gas plates through which electrical wiring is inserted therein.

[Action]

In the present invention, since the door-shaped truss is capable of traveling in the purlin direction by the rail, and the chain block is capable of traveling in the direction between the beams of the door-shaped truss, the chain block is movable together in the direction of the purlin and the beam. After the construction in the free position, the concrete wall can be towed to stand. The chain block can also pull up other materials.

Since the door-shaped truss is mounted on both rails of the foundation, and both the concrete floor and the concrete wall are formed on the foundation, the ground necessary for the hoarding work may be secured simply by laying the rails on both sides of the foundation. Therefore, the opposite two sides of the foundation on the side where it is not necessary to install the rails do not require a working space on the outside of the concrete floor, so that the distance from adjacent buildings can be taken very narrowly.

In addition, in the present invention, a concrete floor is constructed on a foundation, and a concrete wall is formed by using the flatness of the concrete floor, and another concrete wall is sequentially formed by using the flatness of the concrete wall in the horizontal rotation state again. As a result, both the concrete floor and the concrete wall required for the body structure can be constructed at the construction site.

In addition, according to this method, by combining a concrete wall of one layer and then forming a concrete floor of two layers thereon, the concrete wall of the two layers can be sequentially formed using the flat surface of the concrete floor of this two layers.

Therefore, the present invention can be constructed not only in one layer of concrete building, but also in concrete building of two or more floors.

In order to join the concrete floor with the concrete wall and the concrete walls, the ant grooves formed at the time of construction of the concrete floor and the concrete wall are combined, and a reinforcing bar is placed therein to join the concrete. As in the conventional art, it is not necessary to join and join the reinforcing bar or steel frame as in the prior art, and the work can be simplified by increasing the strength of the joint.

When constructing the concrete floor or concrete wall, all necessary pipes such as pipes, water pipes, or gas pipes inserted through electrical wiring are arranged and buried in advance, and the completion of each pipe is completed at the same time as the completion of the body.

In order to assemble the door-shaped truss 24 in the field, first, one truss column 25 is assembled, and the support plate 25a is fixed to the lower end of each truss column 25, so that at least four wheels 26 are mounted. Are arranged on all sides, and two truss columns 25 are mounted on the rails 21 one by one through these wheels 26. In this state, the truss columns 25 and 25 on both sides become free standing, respectively.

Next, each corner of the truss column 25 and the truss beam 27 is opposed to the horizontal load of the door-shaped truss 24 formed by installing the truss beams 27 on both truss columns 25 and 25. Fix the reinforcement (28). The truss column 25 and the truss beam 27 is a truss structure of the steel aggregate and a structure that can be assembled and disassembled in the field.

A transverse rail 29 is laid in the inter-beam direction along the bottom surface of the truss beam 27.

The chain block 31 is provided freely to travel along the transverse rail 29.

The chain block 31 has a general structure that starts with an electric motor, and can be remotely controlled by a push button cord not shown.

The block 31 can be moved to a free position.

Here, the construction of the body construction to be built on the base 11 will be described with reference to FIGS.

First, as shown in FIG. 2, the floor temporary frame 12a is fixedly installed to fill the gap of the base 11, and the top surface formed by the base 11 and the floor temporary frame 12a is made flat. After laying the temporary frame 12b for the cross section along the side of the foundation 11, assembling the reinforcing bar 6 or steel frame on the floor temporary frame 12a, the raw concrete 20 is introduced only by a predetermined thickness The plate of the concrete floor 1 is formed. In the bottom surface of this concrete floor 1, the hole part 13 and the step part 14 are made empty as needed.

Before the raw concrete 20 is introduced, all necessary piping 7 such as a pipe, a water pipe, or a gas plate through which electrical wiring has been inserted is arranged and buried in advance.

As this piping 7, when the plastic pipe rich in corrugation | flexibility is used, it can arrange | position avoiding the internal reinforcing bar 6 and the like.

Moreover, when forming the concrete floor 1, as shown in FIG. 9, the ant groove 3 is formed in the required part of the joint surface with the concrete wall 2 mentioned later. The method for forming the ant grooves 3 may be arranged by arranging the ant groove-type plate at the forming position and removing the ant grooves after the concrete is hardened.

Next, in FIG. 3, the upper surface of the hole 13 is closed with a sheet or closed with a foamed plastic sheet, and the stepped portion 14 roughly covers the bottom surface of the concrete floor 1, such as providing a temporary frame. After flattening, a spacer 4 such as a vinyl sheet is placed on the upper surface of the concrete bottom 1.

This vinyl sheet is most suitable as a peeling material because it is excellent in peelability with concrete and inexpensive.

Then, a temporary wall for wall 5 for forming the periphery of the concrete wall 2 is provided on the separation member 4, and the thickness equivalent to the thickness of the wall 2 is provided in the openings 15 such as the entrance hole and the window hole. After laying the foamed styroline resin plate 16, the steel frame or reinforcing bar 6 is assembled and the raw concrete 20 is introduced to form a concrete wall (2).

In addition, in FIG. 3, two concrete walls 2 and 2 are simultaneously formed on the upper surface of the release material 4 on the concrete floor 1. This shows the possibility of constructing two concrete walls 2, 2 in terms of the concrete floor 1. In this case, if necessary, two temporary wall frames 5 for wall are provided.

In addition, when the joint surface between the concrete floor 1 and the concrete wall 2 or the concrete walls 2, 2 is joined together with an adhesive or a sealing material, the bonding force between the joint surfaces of each other is enhanced and water infiltration is also achieved. Can be prevented.

The building body is completed by the above process and at the same time it is embedded in concrete

Since the piping 7 has completed all its implementations, it can attach a wiring installation, a tap of a water supply, a gas appliance connection port, etc. immediately.

Moreover, a stake is attached to the upper end of the concrete walls 2, 2... In this case, the door truss 24 and the chain block 31 may be used. In addition, when the upper layer is formed on the concrete walls 2, 2, the bottom of the two-layer part is constructed in accordance with the conventional method, or as shown in FIG. The ant grooves 3, 3... Are formed, and the bottom of the two-layered portion is the lowest concrete floor 1 described above, and the two-layered portion is rolled thereon in the same manner as above.

In addition, in the present invention, the door-shaped truss 24 and the chain block 31 are described for standing of the concrete wall 2, but after the concrete wall 2 is standing up and joined, the door-shaped truss 24 It can be used for decorating walls, attaching roofs, etc. Moreover, other materials etc. can be pulled up by this chain block.

[Effects of the Invention]

As described above, according to the construction method of the concrete house of the present invention, by using the flatness of the concrete floor and the upper surface of the concrete wall formed in the horizontal rotation state as it is, the other concrete floor and the concrete wall in the horizontal direction sequentially The present invention can be constructed in a narrow site where all concrete plates can be dried inside the building without using a temporary frame for walls in the conventional construction method, and there is no room to install a conventional temporary frame. Construction of building is enabled.

In addition, it is also applicable to a multi-storey concrete house by repeatedly constructing the above method sequentially.

In addition, the work of erecting the concrete wall can be performed by using a chain block movable in the direction between the beam truss and the beam in the direction of the purlin, and standing the concrete wall after hardening. It can reduce or eliminate the necessary ground for crane use.

In addition, the joining method by the ant grooves employed as the joining means of each concrete member is excellent in the unity between the members to be joined and can realize a high-strength joint structure, moreover, filling the concrete as a plastic body in the opposing ant grooves Therefore, even if a mismatch occurs between the ant grooves of each other, the storage of the concrete members to be joined can be prioritized and connected.

In addition, when constructing concrete floor or concrete wall, all necessary piping such as pipe, water pipe or gas pipe through which electric wire was inserted in advance is buried. Therefore, the effort of piping after completion of body is omitted, and the floor or wall inner pipe Sea angle can also be performed collectively at the time of formation of a concrete floor and a concrete wall.
