Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method of constructing a reinforced concrete plate by pouring concrete onto a concrete form in order to construct the roof or floor of a building. It is something.

[Conventional technology]

Conventionally, as shown in Japanese Patent Application Laid-Open No. 61-95166, a method for constructing the above-mentioned reinforced concrete plate-like body has been such that the horizontal cross-sectional area of the middle part in the vertical direction is One method of construction is to use concrete leveling blocks molded into small shapes.

In this construction method, a large number of the blocks are installed on a concrete formwork at mutual intervals, a reinforcing bar assembly is made on the formwork, and the longitudinal and horizontal reinforcements of this assembly are placed in the middle part of the blocks. After that, concrete is poured onto the formwork, the blocks are embedded together with the reinforcing bar assembly in the concrete, and the blocks are used as markers for the thickness of the poured concrete, thereby making the thickness of each part of the concrete uniform. I'm trying.

[Problem to be solved by the invention]

In the conventional method of constructing a reinforced concrete plate as described above, the leveling block is an integrally molded concrete product, so it is heavy and difficult to handle. Horizontal and G. There are problems in that the degree of freedom regarding the reinforcement arrangement at the bottom is small, and if the thickness of the concrete plate to be cast differs, blocks with different heights must be manufactured each time, which is troublesome. Ta.

The present invention solves the above-mentioned problems and improves the leveling blocks! In addition to making the Jim lighter and improving its workability during transportation and installation, it also improves the workability during installation by dividing it into multiple parts, and also increases the degree of freedom in arranging the reinforcing bars in the reinforcing bar assembly. Furthermore, it is an object of the present invention to provide a method for constructing a reinforced concrete plate that can be reliably embedded and fixed in concrete and that can easily accommodate the construction of concrete plates of different thicknesses.

(Means for Solving the Problems) A method for constructing a reinforced concrete board according to the present invention is to integrate a lower base having a lower reinforcing bar holding part, an upper reinforcing bar holding part and a plurality of legs protruding downward from this holding part into one body. Using a leveling block in which the main body and the lower stand are made of synthetic resin molded products, a large number of the lower stands are molded into a concrete mold by holding the lower reinforcing bars in the lower reinforcing bar holding parts. After fixing on the frame at mutual intervals, a reinforcing bar assembly is made on the formwork, supporting and fixing the legs of the block body on the lower stand, and holding the upper reinforcing bar in the upper reinforcing bar holding part, Thereafter, concrete is placed on the formwork to a thickness that approximately matches the height of the entire block including the main body and the lower stand, and the lower reinforcing bars and upper reinforcing bars are buried in this concrete.

In addition, another method for constructing a reinforced concrete board according to the present invention includes, in addition to the above-described construction method, a leveling block including a height adjusting member having a joint leg interposed between the lower base and the block body; The connecting legs of the height adjusting member are each fixed on the lower stand fixed on the concrete formwork, the legs of the IFf block main body are supported and fixed on these connecting legs, and the main body and the height adjusting member are fixed. This is in addition to pouring concrete to a thickness that approximately matches the height at which the base and the base are fixed.

[Effect]

The method for constructing a reinforced concrete board according to the present invention is that after constructing a concrete formwork, the lower stand of the leveling block, in which the lower reinforcing bar is held in the lower reinforcing bar holding part, is nailed and glued to the appropriate position on the formwork. etc., and then place it on the formwork described in 1 vertically, horizontally and above. Arrange the reinforcement below and set up the reinforcing bar assembly.
Furthermore, the block body is fixed on the lower stand and the upper reinforcing bars are held in these holding parts, or the block body holding the -F reinforcing bars is fixed on the lower stand, and in this state, concrete is placed on the formwork as described above. By pouring the concrete to approximately the same height as the top surface of the main body, the thickness of the concrete can be easily made uniform in all parts by marking the top surface of the main body as L1. In addition, in the present invention, the f stand and the block body of the leveling block are made of synthetic resin molded products, so it is lighter than the conventional leveling block made of concrete, and the lower stand can be mounted on the formwork. After fixing, by fixing the main body to these, even if there is a slight error in the position of the reinforcing bars in the reinforcing bar assembly, the legs of the main body can be bent, or if there are many legs, the main body can be fixed at once. By cutting off the leg portions of the parts, the main body can be easily fixed to the lower table 1F, which improves workability during transportation and assembly, and provides a large degree of freedom in arranging reinforcement.

Since the F platform is fixed to the formwork when concrete is poured, the leveling blocks do not move inadvertently. Since the reinforcing bars are embedded, the base and main body will not come off when removing the concrete formwork after the concrete has hardened. Moreover, the lower stand,
The lower and upper reinforcing bars on the main body can also be used to attach roof panels, ceilings, and other components.

In addition, in another method of elliptical construction of a reinforced concrete board according to the present invention, a height adjustment member is interposed between the lower stand and the main body, so it is possible to use the same lower stand and block main body as the leveling block described above. By changing the number of height adjustment members and the length of the connecting legs, the total height of the leveling block can be easily changed, making it possible to easily change the overall height of the leveling block, which can be used when the thickness of the concrete poured into the concrete formwork is different. Can be easily handled.

It may be positioned and fixed in the height direction, and the number of legs of the block body can be increased or decreased as appropriate.

Furthermore, in both of the above embodiments, the case where the leveling block according to the present invention is used for a roof with a slope is explained, but the leveling block according to the present invention is not limited to one having a slope.
Can also be applied to horizontal/J roots and floors.

〔Effect of the invention〕

As explained above, according to the present invention, a leveling block including a lower stand having a lower reinforcing bar holding part, an upper reinforcing bar holding part, and a block body with leg parts protruding below this holding part is used. , F platform with the lower reinforcing bar held by the lower reinforcing bar holding part is fixed in place on the concrete formwork by nailing, gluing, etc., and then vertically attached to the formwork -F. A reinforcing bar assembly is provided by arranging reinforcement on the side, top, and side, and further, the block body is fixed on the lower stand and the upper reinforcing bars are held in these holding parts,
Alternatively, place the block body holding the upper reinforcing bar on the lower stand -t-
, and in this state pour concrete onto the formwork to almost the same height as the 12 sides of the main body.
The thickness of the concrete can be easily equalized in each part by marking the upper surface of the main body as a mark 1. According to the present invention, the lower base and block body of the leveling block are made of synthetic resin molded products, so they are lighter than conventional leveling blocks made of concrete.
In addition, by fixing the F platform to the formwork -1- and then fixing the main body thereto, even if there is a slight error in the position of the reinforcement of the reinforcing bar assembly, the legs of the main body can be bent. Or, if there are many legs, by removing some of the legs,
It can be easily fixed to the main body on the lower stand, and therefore has good workability during transportation and assembly, and has a high degree of self-alignment with respect to the reinforcement. When pouring concrete, the lower platform is fixed to the formwork, so the leveling blocks do not move inadvertently.
- Lower stand inside, lower held by the main body. Since the upper reinforcing bars are embedded, the lower stand and main body will not come off when removing the concrete formwork after the concrete has hardened. Moreover, the lower and upper reinforcing bars held by the lower base and main body can be used for attaching members such as roof panels and ceilings.

In addition, according to another method of constructing a reinforced concrete board according to the present invention, a height adjustment member is interposed between the lower stand and the wooden body, so that the height adjustment member is the same as the leveling block described above. By using the block body and changing the number of height adjustment members and the length of the connecting legs, the total length of the leveling block can be easily changed. This has the advantage that it can be easily handled when the thickness of the material is different.
