Description

[Detailed Description of the Invention] This invention speeds up slab pouring by only using horizontal joints of slab pouring templates, mutual attachment of reinforcing bars of the joined horizontally mounted templates, and concrete pouring process. The purpose is to produce it reliably.

Therefore, in the past, when pouring this type of slab, a formwork was inserted between the densai beams, and this formwork was supported and reinforcement was placed on the inner surface of the formwork. After the surface was polished, concrete was poured and cured, which would have required a lot of work and equipment for slab construction.In other words, in the previous method, the frames were assembled one by one. Naturally, it was necessary for carpenters to form and support the molds, and reinforcements to be placed by reinforcement workers. However, constructing the upper structure on the slab immediately caused various inconveniences.Of course, after curing, it was necessary to remove and carry out the used formwork, and organize the formwork materials. , repair was requested, and a lot of work and effort was spent on kneading 5 and the like. In addition, it was requested that the demolded surface, especially the ceiling C:, be roughened 2, and that the surface be finished by a plasterer or the like, such as chiseling and chipping.

In the method of constructing a slab according to the present invention, a reinforced concrete plate reinforced with a 1 m alkaline glass cloth material is used, and when this plate is formed, the slab reinforcement is integrated with the cover plate. The present invention eliminates the need for formwork construction, shoring treatment, and reinforcement treatment in the prior art described above, as well as demolding and surface finishing treatment after Jmm. In order to achieve the desired effects of the above-mentioned characteristics, the gist of the construction is a slab in which reinforcing bars for the slab are integrally erected on the surface of a reinforced concrete plate formed with alkali-resistant glass cloth interposed therein. The casting templates are successively connected horizontally between the construction beams, and the formwork reinforcing bars are attached to each other one by one, then concrete is poured over the surface of the casting template until the template reinforcing bars are fully embedded. The following is a specific example, with considerable design changes accompanying this example. Hereinafter, the present invention; the construction of a rolling slab is shown in the drawings. To explain one typical example, (1) is a cloth made of alkali-resistant glass material, which is laminated in two or more layers with the intention of creating strength; (2)
is a reinforced concrete plate using these crosses 1.1) to (1) as intervening reinforcing materials, and is a reinforced concrete plate (
2) is one in which 3 to 8 wt% of alkali-resistant glass fiber chopped is mixed as required.

A wavy connecting part i″rFI+31 on the plate (2)
a to 13) On the upper and lower surfaces of the wave, connect the perpendicular staggered reinforcing bars 131 b and 131 b so that the waves in a are facing in the same direction. Separately reinforcing bars 131c, 131c f
The reinforcing bars (3) and plate 12) are integrated by welding or bundling them together, and by burying the lower connecting part in the plate (2). In integrating the reinforcing bar 13) with the plate (2),
In order to improve the embedability of reinforcing bars 1 for plate (2), rib (2) a is planned to have a thicker plate thickness at the buried part, and furthermore, the lower surface of plate (2), That is, during slab molding, it was separately planned to provide similar ribs for decoration on the end faces that were to form the ceiling.

A board (2) consisting of the following structure is hung horizontally between beams (4).
The slab is directly joined and the opening surface between the beams (4) is completely closed to form the pouring surface of the slab.
) is a long piece that can be immediately hung horizontally between beams (4) or auxiliary beams, and the connecting horizontal frame of plate (2) and plate (
2) - (2) The basic pouring surface construction is completed with the correct attachment of the mutual reinforcing bars (3).

Next, after providing a trough for manning on this template 12), concrete (5) is poured on the surface of the plate (2),
Slab construction has been completed.

Generally, concrete (5) is cast so that the reinforcing bars 13) are sufficiently buried, and a surface treatment is separately applied.

In the method of constructing a slab according to the present invention, there is no need to carry out construction of the formwork one by one, and by simply arranging the plates (2), formwork construction 1: +15, shoring treatment, and reinforcement treatment are performed. 14■1
After completing all of the steps above, the W-shaped slab was completed by simply pouring concrete 11-51 onto the temporary (2) surface.
Sen θ) All construction is unnecessary! It was made as follows.

Therefore, in the construction method of the present invention, the construction cost is particularly low, and the construction period is shortened. It guarantees uniform quality (11), and particularly guarantees the strength of the molded slab (11), and also ensures good impact and bending strength properties on the ceiling surface, which is the bottom of the plate. 1. In addition to preventing accidents such as cracks in the extraction part, it is also possible to use the board (2) itself as a ceiling surface (!).

Claims (1)

[Claims] Slab casting templates, which are made by scraping them so that the reinforcing bars for the slab can stand integrally on the reinforced concrete plate surface with alkali-resistant l 11 glass cloth interposed therein, are successively joined horizontally between the borrowed construction beams, and then the cough templates are made. A method for constructing a slab, which is characterized in that after reinforcing bars are mutually bonded, concrete is cast and cured on the surface of the mold board until the reinforcing bars of the mold board are fully embedded.
