The present invention relates to a composite joint member for waterproof construction, and a waterproof fiber sheet waterproofing method of the structure using the same, after the urethane is applied to a predetermined width on the floor to be waterproofed by attaching the composite joint member, and the waterproof fiber sheet The edge of the composite joint member is laid, and the urethane is applied and dried on the upper part of the composite joint member, and the urethane is applied to the entire surface to form a urethane layer, and the top coat is coated and dried to finish the structure. It is applied to construction structures such as roofs, bathrooms, kitchens, and civil structures such as overpasses, underpasses, and bridges to waterproof structures.

In general, in the roof waterproofing method mainly used among building structures, the urethane waterproofing method is to clean up the rooftop floor to be constructed, apply a primer to the floor to be sufficiently impregnated to dry the floor, and then apply urethane waterproofing on the floor surface to dry It is a method of forming a urethane coating film of a certain thickness and waterproofing it, which is characterized by the excellent elasticity and waterproof function of the urethane coating film to cover even the minute cracks of concrete, but it is too low High temperature or severe temperature changes, large cracks on the roof of the concrete floor will damage the urethane coating, which will continually lift up and lose its waterproofing ability. Moreover, if the urethane waterproofing method is applied to a parking lot with lots of vehicles, it will be repeated. Urethane coating film by load This is by lifting phenomenon occurs as soon as a leak is occurring quickly, there is a problem in the life of the waterproof construction to be shorter.

In addition, there is a prior art waterproofing method using an asphalt waterproof sheet, which is laid on the concrete waterproof asphalt, the urethane is applied to each joint, as the urethane liquid flows into the bottom of the asphalt waterproof sheet In the process of applying urethane to the joints second and third to solidify to form the I-type structural joints, asphalt is melted by the volatile components included in the urethane and thus is not adhered to each other. There was a problem in that the urethane I-type structural joints are formed, which results in deterioration of waterproof performance.

Therefore, the present invention has been made to solve the above-mentioned problems, the non-woven fabric, a narrower than the non-woven fabric, glass fiber mesh laminated sequentially and a composite joint member sewn along the center, the bottom surface of the fiber sheet formed of a nonwoven fabric It is equipped with a waterproof fiber sheet attached with a waterproof synthetic resin film of a narrower width, and after applying urethane to a certain width on the floor to be waterproofed according to a baseline, attaching a composite joint member, spreading the waterproof fiber sheet, Is inserted into the composite joint member, the urethane is applied and dried on the upper portion of the composite joint member, and the urethane is applied to the entire surface to form a urethane layer, and through the process of applying and drying the top coat, the process Applying urethane to the fiber sheet inserted in the composite joint member and drying each edge of the waterproof fiber sheet By fixing each of the edges well waterproof, the waterproof synthetic resin film attached to the bottom surface of the waterproof fiber sheet and the urethane applied to the bottom of the composite joint member to ensure that the base tightly waterproof to improve the waterproof performance. have.

Referring to the process according to the invention in detail with reference to Figure 1, as shown in Figure 4, as shown in Figure 4 is provided with a lower member 11 as a non-woven fabric, a glass fiber mesh, the narrower than the lower member 11 A composite joint having a nonwoven fabric 12 and having a glass fiber mesh 13, which is sequentially laminated with the lower member 11, the nonwoven fabric 12, and the glass fiber mesh 13 and sewn along the center thereof. A waterproof fiber sheet 20 having a member 10 and having a waterproof synthetic resin film 22 having a narrower width is attached to a bottom surface of the fiber sheet 21 formed of a nonwoven fabric.

First, the background cleanup and baseline display process (S1) is a step of processing the most important background in the waterproofing work, the waterproof fiber sheet 20 should be clean and smooth without sand, dust, foreign matter, moisture, oil, irregularities on the floor Because it adheres well, the impurities are neatly removed, and if concrete or cement is protruded or lifted, it is completely ground with a grinder. If moisture is left, it causes the urethane coating to lift. Completely remove, and if there are cracks or dents, fill them with sealants, resins, etc. to flatten the base, clean them clean without impurities, and keep the baseline at a distance of or slightly larger than the width of the waterproof fiber sheet 20. It is a basic process that facilitates subsequent processes by marking through drawing or ink work.

And the urethane coating step (S2), the urethane is applied to approximately the width of the composite joint member 10 along the baseline, the urethane is a plurality of chemical reactors that can cause adhesion, the bottom to be waterproof (1) It is applied to the surface is characterized in that it enhances the surface adhesion and adhesion to the adherend.

In the composite joint member attachment step (S3), the composite joint member 10 is attached by attaching the composite joint member 10 so that the lower member 11 goes to the bottom along the applied urethane before the urethane is cured. Part of the urethane applied to the bottom of the cured, the rest is impregnated into the upper portion of the lower member 11, the composite joint member 10 on the upper portion of the urethane applied to a certain width on the bottom 1 to be waterproof It is a structure to be attached.

Subsequent waterproof fiber sheet laying and edge fitting process (S4), the waterproof fiber sheet 20 is laid out as shown in Figure 5, the edge of the protruding fiber sheet 21 is not attached to the waterproof synthetic resin film 22 Along the lower member 11 and the fiberglass mesh 13 of the composite joint member 10 Insert.

In the urethane coating and drying step (S5) of the composite joint member, urethane is applied and dried on the upper portion of the composite joint member 10, and the lower member 11 of the composite joint member 10 and the glass fiber mesh ( 13) sandwiching the waterproof fiber sheet 20 between and fixed up and down respectively.
