Description

Waterproof nail for corrugated asphalt shingle concrete structure

Technical Field

The utility model relates to a waterproof nail, especially a waterproof nail for wave form asphalt shingle concrete structure belongs to building element technical field.

Background

With the rise of self-assembly buildings, lightweight roofing systems, represented by corrugated asphalt shingles, including resin shingles and polyvinyl chloride plastic shingles, have become increasingly popular. But this type of tile can't directly mat formation on fine aggregate concrete's pitched roof, and traditional steel nail physical connection can't be directly nailed into fine aggregate concrete layer with the steel nail, and firstly is difficult to nail into, secondly can cause the fracture of fine aggregate concrete layer after the forced nailing because the thickness on fine aggregate concrete layer generally is 4CM, and the label is lower. Under the condition, the traditional construction mode is to additionally install the battens on the sloping roof of the fine aggregate concrete by using expansion bolts, and finally, the tiles are nailed on the battens. The traditional construction mode greatly wastes financial resources, material resources and time. In addition, can effectively fix and can not make fine stone concrete layer fracture with expansion bolts, but expansion bolts diameter is thicker, and it is great to the tile destruction to punch, twists the nut and wastes time and energy again, and the unable sealed tile of nut on the tile has caused the destruction to waterproof construction again. How to combine the less penetration damage of the steel nail and the fixing advantages of the expansion bolt is the main direction of development. In practice in the later development period, the American style core-beating expansion nail basically meets the construction requirement of nailing fine aggregate concrete, but the structure of the top cap cannot completely seal the nail hole of the tile.

If a special steel nail can directly and effectively and firmly connect the tile with the fine stone concrete layer, the roof assembly is undoubtedly a great progress, the expenditure of hanging the tile strips is saved, and the construction speed is improved.

Detailed Description

The following will further explain the waterproof nail for corrugated asphalt shingle concrete structure according to the present invention with reference to the specific embodiment and the attached drawing 1.

The utility model discloses a waterproof nail for wave form asphalt shingle concrete structure, as shown in fig. 1, including the nail body 1 and expansion pipe 2, 2 bottoms of expansion pipe are provided with inflation position 21, and the nail body 1 inserts in the expansion pipe 2. The nail body 1 comprises a nail cap 11 and a nail head 12, a sealing limiting part 13 is sleeved on the nail body 1 at the bottom of the nail cap 11, and a waterproof cap 4 is further buckled on the outer side of the nail cap 11. The waterproof cap 4 is a plastic or rubber waterproof cap. The waterproof cap 4 is integrally formed of a top rounded cylinder 41 and a bottom cone 42. The rounded cylinder 41 encloses the nut 11 and the partial seal retainer 13. The top end of the expansion pipe 2 is provided with an expansion seat 22, and the center of the expansion seat 22 is provided with a groove 23. The shape of the recess 23 matches the shape of the seal retainer 13, so that the seal retainer 13 can extend into the recess 23.
