Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for constructing a deck plate, in which a base material such as mortar is placed on the deck plate, and a floor finishing material or a waterproof sheet is laid thereon. In the present invention, the deck plate is
This includes all metal plates in which concave portions and convex portions are alternately formed.

Detsuki plates are widely used in floor structures and roof structures of buildings such as high-rise buildings because they are easier to construct and can make buildings lighter than other floor structures or roof structures. It is used. This deck plate is placed and fixed on a joist or a beam, and is used as a floor or ceiling (roof) of a building. Although deck plates alone are the easiest to construct and are lightweight, they are not suitable as a fireproof structure. Furthermore, in this case, it is not suitable as a floor for walking on, and furthermore, it cannot be used for roofs that require waterproofing. Therefore, usually a base material such as mortar or pea gravel concrete is poured to an appropriate thickness on top of the deck plate, and a floor finishing material or waterproof sheet is laid on top of it to create a walking floor or a regular roof. It is used.

However, in the conventional deck plate construction method, which involves placing a base material such as mortar or concrete and then laying a flooring material or waterproof sheet on top of it, the deck plate does not have water permeability. The residual water contained in foundation materials such as mortar and concrete dries slowly, requiring a long period of time for construction, and is likely to dry insufficiently, making it difficult to apply floor finishing materials or waterproof sheets on top of this. When installed, there are problems such as the possibility of accidents such as blistering and peeling.

On the other hand, mortar is placed on the deck plate, a pipe with a hole on the side is buried in the mortar, and a vent cylinder that opens or communicates with the top of the mortar is connected to the pipe, and a waterproof pipe is placed on the top of the mortar or above it. A method of draining moisture from the mortar from the top surface of the sheet has also been proposed, but this method cannot be applied to floors or rooftops that are used for walking or other purposes.

The present invention solves the above-mentioned problems, and the construction method of the present invention will be explained below with reference to the attached drawings. FIG. 1 is a cross-sectional view of one example of a deck plate floor according to the present invention. On a deck plate 5 placed and fixed on a beam 6, a base material 3 such as mortar, pea gravel concrete, etc. is applied to an appropriate thickness. to be poured. Next, a tubular body 4 having a number of holes on the side surface is buried in the base material. In this case,
Of course, the tubular body 4 may be placed in a desired state on the deck plate 5 in advance, and then the base material 3 may be cast to bury the tubular body. In addition, in order to prevent cracks from occurring when casting the base material, a last sheet may be buried in the base material. It is important that the tubular body be buried in a base material such as mortar and below the concave portion of the deck plate. This is because excess water in the base material is most likely to accumulate below the recess of the deck plate, and by embedding the tubular body there, excess water can be efficiently and completely removed. In other areas, it is difficult to completely remove excess water.

Both ends or at least one end of the tubular body buried in this way is opened to a drainage groove, passage, or void formed at a desired position on or near the wall. When it comes to drainage, the amount of water in the base material that permeates into the tubular body is limited, and it gradually permeates in small amounts, so water is drained out in the same way as water flowing out of a water pipe. do not have. Drainage in the present application can be considered to mean water dissipating as water vapor, or at most a small amount of water dripping. Therefore, it is sufficient that the drainage groove or the like is in a state where the water can be discharged into the atmosphere through the voids in the wall or the like. Therefore, various methods can be used to open the end of the tubular body, as described above, but the easiest method from a structural standpoint is to open the end in the gap formed between the interior wall material and the outer wall. It is. After burying the tubular body, the base material is cured and solidified, excess water is completely removed, and then floor finishing material 1 is laid down using adhesive 2 or the like.

As described above, the present invention embeds a tubular body having a large number of holes on the side surface in a base material such as mortar or concrete cast on a deck plate and below a concave part of the deck plate. Drainage grooves or passages formed at one end on or near a wall;
The opening is made into a gap or the like, and the moisture in the base material is discharged to the outside through the tubular body. Therefore, there is no need to provide a vent on the floor or on the rooftop as in the past, making it extremely effective especially in walking areas.

The tubular body 4 may be one or more than one. In addition, a fibrous material may be inserted into the tubular body or wrapped around the outer surface thereof, or a combination of both may be used. When a fibrous material is used in this way, moisture can easily move to areas where there is no moisture due to capillary action, and evaporation is promoted, which is more effective in drying the base material quickly.

The construction method of the present invention can also be used as a construction method for roofs such as rooftops, if a waterproof sheet 7 is laid in place of the floor covering material, as shown in FIG.

As described above, the present invention removes excess water contained in the base material by embedding a tubular body with many holes on the side in the base material cast on the deck plate. This makes it possible to dry foundation materials such as mortar placed on deck plates that are not highly water permeable much more quickly and completely than in the past. Therefore, it is not only possible to significantly shorten the construction period, but also to prevent accidents such as blistering, peeling, etc. due to the influence of moisture on floor finishing materials and waterproof sheets that are laid using adhesives etc. on the base material. This makes it extremely useful.

The floor finishing material used in the present invention may be any of those commonly used as floor finishing materials, such as synthetic resin floor finishing materials, wood floor finishing materials, carpets, and inorganic floor finishing materials. , etc. can be used. Furthermore, as the waterproof sheet, a synthetic resin waterproof sheet, an asphalt roofing sheet, etc. can be used.

The material of the tubular body may be synthetic resin, metal, wood, etc., and its shape and dimensions may be freely selected. The fibrous materials to be inserted or wrapped around the tubular body include inorganic fibers (e.g. asbestos fibers, glass fibers, etc.), natural fibers (e.g. wool, pulp, etc.), synthetic fibers (e.g. nylon fibers, polyester fibers, polyvinyl fibers, etc.). (alcohol fibers, etc.) and composite fibers thereof, and the form thereof may be appropriately selected as desired, such as woven fabrics, nonwoven fabrics, or short cut fabrics.

As the base material, inorganic materials such as mortar, concrete, gypsum, alumina cement, etc. that can become fluid due to moisture and eventually harden can be used.
