FIGS. 1A to 1E illustrate a roof waterproofing method according to the present invention. The construction and operation of a corner bar provided with a ventilation path will be described in the course of explaining the roof waterproofing method.

First, the roof waterproofing method of the present invention carries out a first step of cleanly arranging the bottom surface 21 of the rooftop on which the waterproof sheet 10 is to be installed. In other words, flattening the surface of the bottom surface and unevenness, such as dust, stone dust, oil and other impurities, clean thoroughly after drying.

Next, as shown in FIG. 1A, a second process of fixing and fixing the corner bar 30 having the ventilator in the lateral direction along the corner where the bottom surface 21 of the roof and the wall surface 22 meet is performed .

It is preferable that the corner bar 30 is produced by extrusion molding a synthetic resin material having the same softness as that of the waterproof sheet 10, and then cut to an appropriate length so as to be used. 2 and 3, the corner bar 30 is disposed in a diagonal direction between the wall surface 22 and the bottom surface 21 of the roof corner and has an attachment surface (not shown) to which the waterproof sheet 10 is attached 31a of the fixing portion 31 and a fixing portion 31 which protrudes from the inside of the fixing portion 31 and has an end contacted with the bottom surface 21 and the wall surface 22 to support the fixing portion 31, Sectional shape composed of first and second support portions 33 and 34 that form a vent path 32 between the surface 21 and the wall surface 22 and the fixing portion 31. [

The end of the fixing part 31 is formed to be spaced from the bottom surface 21 so that the vent 35 is formed between the bottom surface 21 of the roof and the end of the fixing part 31 opposite thereto, (31) is formed with an insertion space (37) into which a sheet-shaped metal member (36) can be inserted so that the waterproof sheet (10) and the high frequency welding machine can be thermally fused. The insertion space portion 37 is provided with an opening portion 37a which is opened toward the attachment surface 31a so that the plate member 36 can be inserted from the attachment surface 31a side of the fixing portion 31. [ The opening portion 37a is formed at the intermediate point of the insertion space portion 37, but may be provided at one end of the insertion space portion 37.

Since the corner bar 30 having such a configuration is made of a soft synthetic resin material, the portion 31b of the fixing portion 31 formed by the insertion space portion 37 is elastically deformed And after the tabular member 36 is inserted into the insertion space portion 37 through the opened opening portion 37a, the portion 31b of the fixing portion 31 is retracted by the self- The plate member 36 can be kept covered.

The corner bar 30 is formed by fixing the upper end of the fixing portion 31 to the roof wall 22 using a fixing nail 38 such as a concrete nail or a knife block, (36) are arranged at a plurality of intervals, for example, at intervals of 1 m, suitable for fixing the waterproof sheet (10) along the longitudinal direction of the corner bar (30).

4 and 5, the corner bar 30 is connected along the corners of the roof so that one inlet 32a and one outlet 32b are formed in the air passage 32. The inlet 32a is provided with an air supply blower 39a for forcibly supplying outside air to the inside of the ventilation path 32 and an outlet 32b for discharging air inside the ventilation path 32 to the outside And an air blower 39b is provided so that air flowing in the air passage 32 is forced to flow. At this time, the supply air blower 39a and the air blower 39b for exhaust use can automatically adjust the operation time by the timer.

Next, as shown in FIG. 1B, a third step of fixing the buried fixing members 40 is arranged at a predetermined interval, for example, 1 m in intervals on the bottom surface 21 of the roof.

The embedding type fixing member 40 is manufactured by injection molding synthetic resin material having the same softness as that of the waterproof sheet 10. 6 and 7, the buried fixing member 40 is composed of a plate-shaped fixed body 41 and a flange portion 42 integrally protruding along the circumference of the lower portion of the fixed body 41 .

The buried fixing member 40 is fixed by being exposed to only the upper surface of the buried fixing member 40 with the adhesive 43 for concrete after being inserted into the fixing groove portion 23 formed on the bottom surface 21 of the roof, The thickness of the buried fixing member 40 and the depth of the fixing groove 23 are set such that the upper surface of the buried fixing member 40 does not protrude from the bottom surface 21. The thickness of the fixing body 41 is set to be thin It is preferable that the groove portion 23 is not formed too deep and a plurality of engagement holes 42a are formed in the flange portion 42 to increase the bonding force with the adhesive 43 for concrete.

The width of the fixing groove portion 23 is formed to be larger than the outer circumference of the flange portion 42 of the buried fixing member 40. Therefore, by filling the adhesive 43 for concrete into the fixing groove 23, only the upper surface of the buried fixing member 40 can be filled with the upper surface of the buried fixing member 40 while the concrete adhesive 43 is hardened, As shown in FIG.

The embedding type fixing member 40 is formed by embedding a metal high frequency induction plate 44 in the fixing body 41 during injection molding so that the waterproof sheet 10 and the embedding type fixing member 44, (40) is thermally fused and attached.

The positioning recess 41a is formed at the center of the bottom of the fixed body 41 of the buried fixing member 40 and the positioning recess 41a of the recessed fixing member 40 is formed at the bottom center of the fixing recess 23. [ The positioning projecting portion 23a is formed to be fitted in the positioning projection 23a.

This is because the positioning groove portion 41a of the buried fixing member 40 is inserted into the positioning projection 23a of the fixing groove portion 23 when the buried fixing member 40 is inserted into the fixing groove portion 23, The buried holding member 40 can be positioned at the center of the fixing groove 23. [

Therefore, when the buried holding member 40 is biased to one side in the fixing groove 23, it can be prevented that the holding force is biased to one side of the buried holding member 40 when the latter is fixed by the adhesive 43 for concrete It is possible to eliminate the trouble that the operator has to adjust the buried-type fastening member 40 to accurately locate the buried-type fastening member 40 in the center of the fastening groove 23.

The heat welding technique using such a hot air blower or high-frequency fusion welding machine is a well-known technology, and a detailed description thereof will be omitted.

By using the buried fixing member 40 in adhering the waterproof sheet 10 to the roof bottom 21 as described above, it is possible to maintain the fixing portion of the waterproof sheet 10 as a whole as flat as possible or to minimize the protrusion phenomenon The appearance of the waterproof construction can be maintained in a good condition and the damage due to the abrasion of the protruded portion of the waterproof sheet 10 can be prevented and the waterproof sheet 10 can be firmly fixed, Can be prevented.

Since the waterproof sheets 10 are formed in the form of rolls having a constant width, they are arranged in parallel on a large area of the roof, and the adjacent waterproof sheets 10 are partially overlapped and thermally fused with hot air.

Therefore, the operation of attaching the buried holding member 40 and the waterproof sheet 10 and the operation of attaching the overlapped portions of the waterproof sheets 10 are alternately repeated.

Next, as shown in FIG. 1E, a sixth step of attaching the waterproof sheet 10 and the fixing portion 31 of the corner bar 30 by heat fusion is carried out.

10, the attachment surface 31a of the corner bar 30 and the bottom surface of the waterproof sheet 10 are adhered together by hot-air or high-frequency fusion welding. In the case of using hot air, The mounting surface 31a of the corner bar 30 and the bottom surface of the waterproof sheet 10 are melted by hot air blowing between the mounting surface 31a of the waterproof sheet 10 and the bottom surface of the waterproof sheet 10, In the case of using a high-frequency fusion splicer, the metallic plate member 36 is heated by the high-frequency induction current from the upper surface side of the waterproof sheet 10 so that the adhesion surface 31a of the fixing portion 31 and the waterproof sheet 10 The bottom surface can be melted and thermally fused.

As described above, since the waterproof sheet 10 is installed at the corners of the roof by the corner bar 30 very quickly and conveniently, workability is good and the waterproof sheet 10 is firmly fixed at the corner of the roof It is possible to prevent damage due to lifting of the waterproof sheet 10.

The gap between the waterproof sheet 10 and the bottom surface 21 and the gap between the waterproof sheet 10 and the air passage 32 are formed through the air vent 35 formed between the end of the fixing portion 31 of the corner bar 30 and the bottom surface 21 of the roof, The air forcedly flowing through the ventilation path 32 by the blower is also supplied to the gap between the waterproof sheet 10 and the bottom surface 21 so that the moisture generated on the bottom of the waterproof sheet 10 can be removed have.
