Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

1-2, an embodiment of the present utility model provides a technical solution: a steel structure roof joint waterproof structure, including a base fabric layer 1, a sealing groove 2, a bonding groove 4 and a waterproof and breathable membrane 8, the said The bottom of the base fabric layer 1 is provided with a sealing groove 2, the sealing groove 2 is connected to the bottom of the base fabric layer 1 by means of bonding, and the bottom of the base fabric layer 1 is provided with a bonding groove 4. The grooves 4 are located on both sides of the sealing groove 2 .

The inside of the sealing groove 2 is filled with a sealant 3, the sealant 3 covers the outside of the joint, and the sealing groove 2 is attached to the surface of the steel structure roof. It can well seal the joints of the steel structure roof, which is more targeted and more practical.

The bonding groove 4 is in a symmetrical distribution form, the interior of the bonding groove 4 is filled with waterproof glue 5, and the bonding groove 4 is bonded to the surface of the steel structure roof. The bonding groove 4 can bond the base fabric layer 1 to the steel structure roof twice, so as to realize the sealing and fixing of the butt joint and the roof itself at the same time, with strong functionality.

Both sides of the sealing groove 2 are provided with overflow gaps, and the glue overflow gaps are symmetrically distributed on both sides of the sealing groove 2 . In the overflow gap, the sealing work on both sides of the sealing groove 2 is realized, and the practicability is strong.

The base fabric layer 1 is made of stitched polyester cloth material, and the top of the base fabric layer 1 is connected to a waterproof adhesive tape 6 through a polyurethane waterproof coating, and the waterproof adhesive tape 6 is made of butyl rubber and polyisobutylene. The base fabric layer 1 made of stitched polyester cloth has high tensile strength and strong stability, and the service life of the waterproof structure is better improved.

The waterproof surface layer 7 is provided below the waterproof breathable membrane 8, and the waterproof breathable membrane 8 is connected to the surface of the waterproof surface layer 7 by bonding. The waterproof surface layer 7 made of the coil material has strong high temperature resistance, so that the waterproof structure is suitable for use in the case of strong solar radiation, and has strong practicability.

Working principle: When applying the steel structure roof joint waterproof structure, firstly apply the sealant 3 evenly on the joints of the steel structure roof, and then seal the sealant through the sealing groove 2 provided at the bottom of the base fabric layer 1. The groove 2 is aligned with the seam and pressed down firmly, so that the sealing groove 2 tightly wraps the sealant 3. At the same time, because there is an overflow gap outside the sealing groove 2, the overflowing sealant 3 will It flows into the overflow gap, so as to achieve the sealing work on both sides of the sealing groove 2. When the sealant 3 solidifies, the joints and the base fabric layer 1 can be tightly bonded together, which greatly improves the quality of the steel. The waterproof performance of the structural roof joints is strong, and then the waterproof glue 5 is filled in the bonding groove 4 through the bonding groove 4 provided at the bottom of the base fabric layer 1, and then the base fabric layer 1 is pressed firmly.
