Partial down slab of bathroom for having pipe on concerned floor and construction method

The present invention relates to a bathroom slab and a construction method thereof for plumbing the floor, and more particularly, a portion of the bottom slab protrudes downward along a longitudinal direction or a width direction of the floor slab and the floor slab forming the bathroom floor. PC slab consisting of slab; A slab wall extending vertically upward along a part circumference of the down slab, the pipe having a hole for piping; A pipe installed in an upper portion of the down slab through the slab wall; Floor filling material is filled on top of the PC slab to form a bathroom floor; It relates to a bathroom slab and a construction method for the plumbing layer, characterized in that consisting of.

The Housing Performance Rating Labeling System has been implemented in more than 2000 apartment complexes since January 2006 with the aim of improving the quality of apartments and delivering accurate housing information to tenants to induce the production of quality housing. From 2008, it will be expanded to more than 1000 households.

In the housing performance rating system, the performance items for evaluating and marking housing performance ratings are divided into five parts: noise, structure, environment, living environment, and fire and fire. At this time, the evaluation of noise-related grades is evaluated by dividing into four performance categories of light impact sound, heavy impact sound, toilet noise and boundary noise. The toilet noise evaluation here is judged to be to induce the adoption of the relevant reduction method for the noise of the toilet drainage and air transfer between the upper and lower floors through AD (air duct) to ensure the quietness of the indoor space. One example is the adoption of the layer piping method.

Unlike the direct pipe piping method in which a pipe for the pipe of a drainage pipe is drilled on a concrete slab, the pipe pipe construction method (or upper pipe piping method) is a method of directly generating a tub, a sink, a toilet, etc. It is a method of relatively little effect of noise transmitted to the (Fig. 1).

As a construction example of the layer piping method, a down slab type and a flat slab type can be considered as shown in FIGS. 2A and 2B. However, the down slab type has a disadvantage in that the relationship between the finishing height of the living room and the wet zone is limited and the layout or change of the plane is not free. In addition, the flat slab type is possible when the living room is finished with a double floor, etc., and the required piping height is sufficiently secured. The flat slab type has a disadvantage in that construction or change of the plane is free, but construction cost increases.

On the other hand, the conventional down slab type is a pull down slab system in which the height is lowered over the entire bathroom floor surface, which is disadvantageous in terms of construction and structure due to the large amount of floor filling material, and does not allow space for installing a ceiling power fan. In addition, in case of a fault in the drain pipe, the entire floor slab had to be pulled out, which made maintenance difficult.

The object of the present invention created to solve the above problems is as follows.

First, to improve the noise-related grades related to bathroom noise by adopting the pipe system of the floor, and to provide a bathroom slab for the floor pipe and its construction method that can achieve economic efficiency and construction by using a small amount of floor filler. .

Secondly, by employing a partially downed slab, it is possible to secure a space for installation of a ceiling type power fan, and to provide a bathroom slab and a construction method thereof for plumbing the floor, which is easy to maintain and repair the drain pipe.

Third, by pre-assembling the bathroom floor slab portion using the precast concrete, to provide a bathroom slab and the construction method for the plumbing layer having excellent workability.

Fourth, the pre-assembled bathroom slab portion and the horizontal member adjacent to each other through the moment bonding, to provide a bathroom slab for the floor pipe piping and the construction method of the load is clear.

In order to solve the above problems, the present invention is to install the floor pipe in the bathroom slab, the bottom slab constituting the bathroom floor and the bottom slab is formed to protrude downward along the longitudinal direction or the width direction of the floor slab PC slab consisting of down slab; A slab wall extending vertically upward along a part circumference of the down slab, the pipe having a hole for piping; A pipe installed in an upper portion of the down slab through the slab wall; Floor filling material is filled on top of the PC slab to form a bathroom floor; It provides a bathroom slab and a construction method for the plumbing layer, characterized in that consisting of.

That is, a part of the bathroom slab is partially down to enable piping of the floor, and at the same time, to minimize the amount of floor filling material and to facilitate maintenance.

In addition, the prefabricated concrete slab was pre-assembled with precast concrete to facilitate the construction, and the site casting horizontal member adjacent to the bathroom slab was designed to clarify the load transfer process through moment bonding.

According to the present invention as described above is expected the following effects.

First, the present invention can improve the noise-related grade associated with the bathroom noise by using the pipe piping method of the above, it is possible to improve the economics and construction by reducing the amount of floor filler.

Second, the present invention can secure a space for the installation of the ceiling-type power fan by employing a partially down slab, and easy maintenance of the bathroom floor slab due to the defect of the drain pipe.

Third, since the present invention pre-assembles the members forming the bathroom slab using precast concrete and connects the adjacent horizontal members to the moment joints, the construction is easy and the load transfer process is clear.
