Description
Technical Field
The utility model relates to a waterproof bolt cap for installing resin tile belongs to building materials technical field.
Background
The synthetic resin tile has various excellent characteristics of light weight, high strength, water resistance, moisture resistance, corrosion resistance, flame retardance, sound insulation, heat insulation and the like, and is generally suitable for flat slope change in development areas, farmer markets, residential quarters, high-grade villas of residents in new rural areas, awnings, sunshades, antique buildings and the like.
When the synthetic resin tile is installed on a roof, a worker generally uses an electric screwdriver to drive in the self-tapping screw, the self-tapping screw is provided with an end exposed out of the surface of the tile after installation, in order to prevent the problems of rainwater corrosion, leakage and the like, the existing treatment method generally uses sealant to coat, however, the sealant is gradually consumed under the long-term rainwater corrosion, so that the outer end of the self-tapping screw is exposed, and the leakage-proof performance of the tile roof is influenced.
In order to solve the problem, the applicant has previously developed a product, which has technical features as described in patent document No. CN208965894U, and which discloses a screw with a cover for mounting a synthetic resin tile, comprising a cover pad, a cap and a self-tapping screw, wherein the cover pad comprises a curved plate attached to the surface of a trough of the resin tile and a snap ring connected to the top surface of the curved plate, the top of the outer side of the snap ring has a first snap edge, the self-tapping screw passes through a mounting circular hole and locks the cover pad to the trough of the resin tile, the inner wall of the cap has a second snap edge, and the cap is fastened to the cover pad by the cooperation of the first snap edge and the second snap edge to cover the screw of the self-tapping screw. This solution enables protection of the bolt head, but also presents some drawbacks.
Because the curved plate that has designed the ripple laminating with the resin tile is in order to guarantee that the rainwater can not permeate and be stained with the bolt from the bottom of curved plate, can not fix curved plate and self tapping screw in advance directly bore into the resin tile together and tighten, because go up the screw in-process curved plate and rotatory along with the self tapping screw, the curved plate does not necessarily just rotate when the self tapping screw is tightened and coincide with the cambered surface of resin tile. Even if the curved plate and the self-tapping screws are not fixed together in advance, a worker holds the curved plate with one hand and tightens the self-tapping screws with the other hand during installation, and the bolt head of the self-tapping screws still drives the curved plate to rotate a little angle due to friction force after contacting with the curved plate, so that the curved plate is difficult to coincide with the arc surface of the resin tile, and the curved plate is not attractive and cannot be tightly attached to influence the waterproof performance.
