Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is applicable to multi-story housing complexes such as condominiums.
This article relates to a waterproofing construction method to prevent damage to the lower floor due to water leakage in the water section.

(Prior art) Usually, parts of apartment buildings that use a lot of water, such as kitchens, washrooms, bathrooms, and toilets, are combined into a water section.

In this water section, water supply pipes, drainage pipes, gas pipes, etc. are laid out on a reinforced concrete floor surface separated by a common pipe space, and flooring material is installed above them.

(Problems to be Solved by the Invention) Water leakage may occur in these water sections due to carelessness in handling.

For example, if water is supplied to a washing machine with the drain hose disconnected, water may spill from the drain hose onto the floor, or the drain port may become clogged and overflow.

When such water leaks occur, conventional cast-in-place concrete floors are not sufficiently waterproof, so water leaks to the floor below through cracks, stains the ceilings and walls of the units below, and water leaks from here. There are some problems that occur.

Furthermore, in buildings with a V-strength structure, although the precast plates are waterproof, water often leaks from the joints around their edges.

In response, the entire floor surface of the water section is sometimes waterproofed with asphalt, but this type of waterproofing is not generally carried out due to cost and complexity of construction. Met.

This invention was made based on the above-mentioned circumstances, and it is possible to make the water section part a completely waterproof floor surface using a simple construction method, and to streamline the installation and construction of piping and equipment such as water supply and drainage pipes. The purpose is to

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a floor surface shape corresponding to the water section of a multi-story housing complex, which is formed into a bread shape with a rising edge on the periphery. Piping is performed in advance on the precast floor slab in accordance with the layout of the equipment units, and the precast floor slab with only the piping section is lifted and fitted and fixed to the wall and slab around the water sex section. It is characterized by what it did.

(Example) Hereinafter, an example of the method of this invention will be described in detail using the drawings.

FIG. 1 shows a tin plate 1 to a floor slab 1 to which the present invention is applied.

The floor slab 1 is formed in a rectangular shape corresponding to the shape of the floor surface of the water section section, and has raised portions 3 provided around the four circumferences of the floor surface, and is formed into a bread shape as a whole. Further, a notch 4 for drainage is formed in a part of the rising portion 3, and the floor surface 2 of the floor slab 1 is formed into an inclined surface that slopes downward toward this notch 4.

Furthermore, cutouts 5 for attaching a clasp are formed at appropriate positions on the upright portion 3 at predetermined intervals.

As shown in Fig. 2, supply, drainage and gas pipes 7 are installed on the floor surface of the tin plate 1 to the floor slab 1 formed as described above according to the arrangement of the equipment units, and the ends thereof are connected to common piping. The focus is on the attraction part.

Although not shown, each vibrator 7 is fixed with a mounting bracket or the like, and in particular, the drainage vibrator has a predetermined slope that slopes downward toward the exit side.

Attach the flooring F via joists, etc. to appropriate positions on the ground surface where the preceding piping ends, and as roughly shown in Figure 3, package the equipment unit 8 such as the bathroom unit, kitchen set vanity unit, and toilet bowl. The installed state is transferred to the construction site, lifted by a crane or the like via the lifting jig 9, and the installation work is completed by fitting and fixing the floor slabs 1 sequentially from the lower floor.

FIG. 4 shows the installation state, in which the peripheral edge of the precast floor slab 1 is engaged with a step 10a formed on the edge of a beam 10 provided for each floor. Furthermore, the flooring F can be removed for inspection.

FIG. 5 does not show the details of the installation of the precast floor slab 1, and the beam 10 has a notch 5 for inserting the roof slab.
A hole 10B for inserting the blade is also formed at the corresponding position, and by fitting the blade 11 into the blade 1 of a predetermined thickness so as to span between the two, and covering the upper part with concrete or mortar, Due to the lateral effect of the tar plate 11, the precast floor slab 1 and the beam 1o
The joints with the two will be joined together in a reinforced state.

Other joints will also be joined using concrete, mortar, asphalt, etc.

Then, by joining the ends of the pipes 7 to an opposing lead-in piping section (not shown) from the common piping via a joint, each vibrator 7 is completely connected to the common piping section.

After that, the equipment unit 8 is unpacked, its water supply and drainage section is connected to each pipe 7, and the installation is installed at a predetermined location, thereby completing the construction of the water section section on each floor.

Note that the IJF water notch 4 connects to a common drainage ditch, etc., and if this joint is sufficiently waterproofed, even if there is water leakage on the floor 2, the water will flow downstairs. There is no risk of it seeping or dripping. however,
To further increase safety, if a water leakage sensor or the like is placed in this area and an alarm output is generated in the event of water leakage, water leakage conditions can be detected early and safety can be further increased.

Further, in the above embodiment, the equipment unit 8 was simply installed on the precast floor slab 1 via the flooring F, but it is pre-assembled on the floor slab 1 in a state where it is connected to each of the pipes 7. You can also place them at each corner of the attached pattern.

(Effects of the Invention) As described above in detail using the embodiments, according to the waterproofing construction method for a multi-story apartment building of the present invention, there is no influence on the downstairs due to water leakage compared to the conventional method, and the construction period is longer.
Since waterproofing can be easily performed without using expensive asphalt waterproofing, construction is easy and the construction period can be extremely short.

In addition, since this invention allows preliminary piping to be performed above ground, it is easy to inspect water leaks that occur at pipe joints, etc., and prevents variations in construction and water leaks that occur due to this. It can be prevented. Furthermore, if the equipment unit 1- is installed and fixed together with the piping on the floor slab in advance, the construction period will be greatly shortened.
