Description

Eccentric Loop Drain on Building Roof {DISCREPANCY ROOF DRAIN}

The present invention provides an eccentric structure to prevent mutual interference between the main pipeline installed near the outer wall of the building and the roof drain mounted on the rooftop, thereby more effectively securing the space inside the building. The present invention relates to an eccentric loop drain on a roof of a building that can be used at the same time to facilitate rooftop masonry.

As is well known, when the roof floor is constructed by a concrete concrete slab, waterproofing is performed to prevent the leakage of rainwater into the building. It is installed so that rainwater or sewage flowing into the slab can be discharged through the main pipe.

In connection with such a loop drain, various publications such as Korean Utility Model Registration No. 034018, 0179274, 00406975, 0413816, etc., have a roof drain on a rooftop floor which is constructed of a conventional slab layer, a waterproof layer, a heat insulating layer, and a finishing layer. Various techniques have been disclosed for this installation to discharge rainwater to the ground.

Among them, for example, the technique disclosed in Korean Utility Model Model No. 0406975 has a bottom portion 12 inserted into the first stage gradient 14 as shown in FIG. An angled body 10 having a drain nipple fastening portion 18 protruding rearward from the side portion 16 so as to communicate with the recessed space 15 of the bottom portion, and the recessed space 15 of the bottom portion 12 and the drain nipple fastening A plurality of coupling parts are screwed to the angular body 10 so as not to be separated from each other and cover the part 18 and communicate the concave space 15 of the bottom part 12 and the drain nipple fastening part 18 with the outside. A structure including an angled drain grating 20 having a drain hole 22 is described, and FIG. 1B also shows a body 60 having a structure as shown in FIG. 1A, and a surface in which the lower part and the rear part are open and exposed to the outside. For a structure having a domed drain grating 70 with a plurality of drain holes 72 formed therein. It is.

When the roof drain constructed as described above is installed on the roof, when the roof top slab 30 and the handrail wall slab 32 are poured while the nipple 34 is connected to the drain nipple fastening portion 18, the angle type The body 10 is fixed by construction, and after curing the slabs 30 and 32, the upper surface of the rooftop slab 30 and the inner wall surface of the handrail wall slab 32 to reach the front end of the body 10. The floor waterproofing layer 40 and the wall waterproofing layer 42 are respectively constructed.

In addition, a protective layer 50 such as a heat insulation layer or a waterproof mortar is formed on the bottom waterproof layer 40, and a waterproof protective wall 52 formed by stacking bricks 54 and the like on the wall waterproof layer 42 and being treated with a finishing layer 56. ) Is formed.

However, in the above-described method, the roof drain can be installed through the drain nipple fastening portion 18 in a state in which the nipple 34 is perpendicularly attached to the main drain pipe perpendicular to the building outer wall. Is complicated and the constructability due to mutual interference or narrow space is very poor.

In addition, since the waterproof layers 40 and 42 are constructed so as not to overlap the angle-shaped body 10 and covered to the boundary surface, the waterproof layers 40 and 42 are easily lifted from the loop drain, and thus, the slab 30 and the gap between the loop drain and the waterproof layers 40 and 42 are formed. Water leakage into the 32) will cause leakage, as well as drainage grating 20 is constructed at the same height as the bottom waterproofing layer 40, so that the water is collected only by the gradient of the protective layer 50. There was a problem.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

First, FIGS. 2 to 5 are diagrams for explaining an eccentric loop drain on a roof of a building according to the present invention. The present invention includes an outer wall 80A, a conventional slab layer 80B, a heat insulating layer 80C, and a waterproof layer ( The roof drain is installed on the rooftop of the building to be constructed with the 80D) and the masonry brick 80E, and the like to discharge rainwater.

Loop drain according to the present invention consists of an eccentric pipe line 83 assembled on the base 82, including the base 82 is fastened to the upper end of the main pipe line 81, of the eccentric pipe line 83 The upper end part is provided with the casing 84 in which the upper surface part is exposed to a rooftop floor, and the hemispherical cover 85 mounted so that detachment is possible on this casing 84. As shown in FIG.

In addition, the base 82 is formed with four protruding pieces 87 each having a step 86a on the outside of the inner diameter of the body and having a through hole 86b outward from each other, and the main body is formed on the bottom of the body. Concave indentation 88 is formed is fitted to the upper end of the pipe (81).

It is possible to fix the base 82 by driving the nail 90 through the through hole (86b) in the state in which the fixing plate 89 is installed around the main pipe (81), the body constituting the base 82 Ribs 86c for strength reinforcement are formed at the outer edges of the edges.

In addition, the eccentric pipe line 83 has an inclined tube 92 interposed between the first and second straight pipes 91a and 91b whose centers are spaced apart from each other, and the outer side of the inclined tube 92 has a circular index plate ( As the 93 is formed integrally, it is possible to correct the position during the construction process or to prevent leakage along the outer surfaces of the first and second straight pipes 91a and 91b or the inclined pipe 92.

On the upper side of the first straight tube 91a, the enlarged diameter portion 91c is continuously formed and an insertion groove 91d is provided inside the insertion pipe 91d, and the insertion groove 91d is made of PVC and is freely cut. 94) can be assembled so that the casing 84 can be seated in the correct position according to the design height.

In addition, the casing 84 has a stepped portion 96b and an insertion portion 96c formed inwardly of the protruding jaw 96a extending from the flange 95, respectively, and has a handle at the upper end of the hemispherical cover 85. A plurality of slits 97b which are cut in the vertical direction, including the balls 97a, are formed.

In the above example, the structure of assembling the base 82 and the eccentric pipe 83 separately from each other has been described. However, the base 82 and the eccentric pipe 83 can be manufactured integrally by synthetic resin or cast iron. Of course you can.

According to the present invention configured as described above, after the reinforcing bars and the formwork are disposed by a conventional method (not shown), the main pipe line 81 is vertically installed on the predetermined fixing plate 89 along the building outer wall 80A. , While assembling and inserting the concave groove 88 formed in the bottom of the base 82 to the upper end of the main conduit 81, and nailing the nail 90 with the through hole 86b formed in the protruding piece 87. Let's do it.

In this state, while mounting the second straight pipe (91b) constituting the eccentric pipe (83) on the base 82 and at the same time to position the first straight pipe (91a), at this time Since the index plate 93 is attached to the outer surface, the position during the construction process can be easily corrected, and the phenomenon of leakage through the outer surface of the first and second straight pipes 91a and 91b or the inclined pipe 92 is also observed. Can be prevented.

In addition, as the enlarged diameter portion 91c and the insertion groove 91d are successively formed on the first straight pipe 91a constituting the eccentric pipe passage 83, the cylindrical pipe 94 can be assembled. The insertion part 96b formed in the lower end part of the casing 84 is inserted in 94, and is fixed.

At this time, since the cylindrical pipe 94 is made of a relatively free cutting PVC material, it is possible to accurately position the casing 84 according to its design height, and the flange 95 of the casing 84 can be used. The hemispherical cover 85 can be seated on the stepped portion 96b formed inwardly of the protruding jaw 96a.

As such, as the eccentric conduit 83 and the casing 84 are placed and cured by placing concrete, the eccentric conduit 83 and the casing 84 may be embedded to form the slab layer 80B. Of course, it is then possible to construct a heat insulating layer (80C) and a waterproof layer (80D).

As described above, the centers of the eccentric pipe line 83 and the casing 84 and the hemispherical cover 85 connected to the main pipe line 83 to form a loop drain can be configured to be spaced apart from each other. By installing the pipeline 83 as close as possible to the outer wall 80A, the interior space of the building can be sufficiently secured, as well as the construction of the roof drain is easier than in the conventional method, and easier to perform roof masonry.

The technical problem of the present invention is achieved by the technical configuration as described above, although the present invention has been described by a limited embodiment and drawings, but the present invention is not limited thereto and is intended by one of ordinary skill in the art to which the present invention belongs.
