The spacer 34 has a function of restricting the height of the upper portion of the case body 32 so that at least a part of the upper portion of the case body 32 is buried by the ready-to-put concrete.

That is, the upper end portion of the case body 32 supported by the spacer 34 can be more protruded than the upper surface of the slab S having a relatively thin thickness, and the slab S ' ), It may occur that it is embedded in the slab S '.

This may be the case when the past slabs are at a level of about 110 to 150 mm thick, or when remodeling a range that does not damage the slabs of existing apartments, when it is a laminate structure, and when it is required that the thickness of the slab is sufficiently thick In other words, it is possible to fix the slab on the slab by using a mortar or the like without using any of the above-mentioned spacers.

The upper portion of the case body 32 may protrude from the upper portion of the slab S such as the lower height. In this case, the protruding height of the case body 32 may be reduced by a waterproof paste or tile, (32) is buried.

According to the current Korean system, the thickness of the foundation slab is set to 210 mm in the case of a house structure having a wall structure, and the living room excluding the bathroom is provided with the above-mentioned interlayer noise- (40 to 50 mm: b / l, 40 to 50 mm: s / p, soundproofing layer) and a heat insulating layer (40 to 50 mm: i / Layer ') and the like.

Accordingly, since the bottom surface of the bathroom which does not require the heating, the heat insulating layer and the soundproofing layer is excessively lower than the bottom surface of the living space, the upper surface of the case main body 32 is covered with the waterproof paste or tile, Can be sufficiently buried.

The height from the bottom to the top of the case main body 32 is determined by considering the fact that the diameter of the purifying tank pipe 30a connected to the toilet machine 16 is approximately 100 mm and that the slab reinforcement R is slabs S, 'May be formed within a range of 120 to 170 mm in consideration of the fact that it is arranged at a height of 30 to 70 mm with respect to the bottom surface.

3, the case main body 32 described above is designed so that the plate material according to the design already set to correspond to the predetermined arrangement of the bathroom structure increasing and leveling pipes is sealed In some cases, the case body 32 may be made of synthetic resin material by injection molding using a metal mold.

The horizontal pipes 30a, 30b and 30c of a predetermined arrangement are housed in the case body 32 through an opened upper part. At this time, a plate material is vertically arranged on the bottom surface and the inner wall surface of the case body 32 A plurality of slots 36 to be fitted are formed along the longitudinal direction of the horizontal pipes 30a, 30b and 30c, The support plate 40 on which the alignment grooves 38 corresponding to the grooves 38 are formed is supported by the slots 36 so that the alignment grooves 38 are located on the upper side.

3, the lower portion of the support plate 40 is in contact with the bottom surface of the case body 32 and is formed on the upper side of the bottom surface of the case body 32 At least one cut portion (cutting line) 42 (cutting line) crossing from one side of the support plate 40 to the other side is provided at a predetermined distance from the lower portion thereof so as to adjust the height of the alignment groove 38.

The cut portions 42 are arranged such that the horizontal pipes 30a, 30b and 30c, which will be described later, are spaced apart from each other by the alignment grooves 38 using a mechanism such as a hand grinder when necessary, (30a, 30b, 30c) in the direction of the horizontal pipe (10).

When the ready mixer for the formation of the slabs S and S 'is poured into the respective slots 36 described above, the pressure is applied to the case body 32, that is, between the inner walls of the case body 32, And a gap supporting member 46 for supporting the gap stably is provided.

The gap supporting member 46 may be made of reinforcing steel having a thickness and durability enough to withstand pressures due to putting remicon or the above-mentioned support plate 40 having a vertically opposite phase.

On the other hand, the outer wall including the bottom surface of the case body 32 described above is formed with engaging protrusions 44 that are fixed to the ready-mix concrete to be firmly fixed to the slabs S and S '.

The engaging projection 44 may be formed such that the thickness of the distal end portion protruding from the portion contacting the outer surface of the case body 32 gradually increases. May be used as a coupling structure in which the upper portion of the spacer 34 is engaged with the upper portion.

As shown in Figs. 3 to 4F and Fig. 6, on the side wall of the case body 32 facing the pipe shaft 10 described above, one side of the case body 32 in the inner direction is arranged inward The other ends of the horizontal pipes 30a, 30b and 30c are connected to each other and the other ends of the horizontal pipes 30a, 30b and 30c are connected to the opposite pipe shafts 10, 48a, 48b, 48c for connection with the first, second, third,

In addition, as shown in Figs. 3 and 6, a lower portion of the side wall of the case body 32 opposed to the pipe shaft 10 is provided below the position of the joint pipes 48a, 48b, and 48c And the other end is connected to the pipe shaft 10 is formed.

The auxiliary pipe 50 is configured to allow the water contained in the case body 32 to flow through the pipe shaft 30 when the horizontal pipes 30a, 30b, and 30c disposed in the case body 32 are damaged or broken, A sponge or various kinds of fibrous materials or porous metal materials to prevent drainage of the soundproofing material 52 into the auxiliary pipe 50. In order to prevent the soundproofing material 52 from flowing out through the auxiliary pipe 50 and the pipe shaft 10, A filter 54 is further provided.

The reason why the construction of the soundproofing material 52 described above is limited to the particle state is that when there is noise transmitted along the pipes 30a, 30b, and 30c due to movement of water and collision between water in the drainage process, The sound insulation material 52 held in a fine to small particle size state is in contact with the pipes 30a, 30b, and 30c, and the energy of the vibration is converted into kinetic energy in such a manner as to flow or vibrate instantaneously 30b, and 30c in the process of being restored due to the buried state, thereby finely vibrating the pipes 30a, 30b, and 30c.

At this time, the vibration generated by the soundproofing material 52 is canceled by colliding with the vibration proceeding along the pipes 30a, 30b and 30c, thereby canceling out the sound of the original water flow .

As described above, when the horizontal piping 30a, 30b, and 30c are aligned and the soundproofing material 52 is filled in the case body 32, 56b, 56c for the vertical installation of the vertical piping or the drain trap 22 to be connected to one end of the horizontal pipes 30a, 30b, 30c).

The lid 58 is preferably made of an adhesive or a sealing material for various gaps so that the airtightness can be maintained so that the wastewater does not flow into the case body 32.
