Abstract

The color steel plate roof connection structure belongs to the field of roof waterproofing of color steel plate buildings. It includes roof purlins and color steel plates. The roof purlins and color steel plates are connected by screws. A piece of inner waterproof pad, the top of the outer waterproof pad is covered with a layer of composite waterproof material layer; the top of the color steel plate is pasted with a layer of composite material; the thickness of the composite waterproof material layer is 4mm, from bottom to top respectively Base rubber layer, polyester non-woven layer and metal aluminum foil layer. The waterproof cushion block of the utility model has very strong bonding force, can firmly adhere color steel plates and screws, block the screw holes, and solve the problem of water seepage in the screw holes.

Description

Color steel plate roof connection structure

The utility model relates to the field of waterproofing of color steel plate building roofs, in particular to a color steel plate roof connection structure.

Background technique

The leakage problem of the self-tapping screw in the existing color steel plate roof is more prominent. Although the screw has a waterproof gasket at the self-tapping screw hole, the screw hole will expand after a long period of thermal expansion and contraction, thus increasing the size of this part. Leakage hazard. In addition, during the construction process, if the tapping force is too heavy or too light, the self-tapping rubber gasket may deform, fall off or form a concave surface if the self-tapping screw is deflected or tilted, causing water leakage on the roof and accumulation through the insulation cotton. The accumulation of less becomes more, forming multiple leaks.

Contents of the invention

In order to effectively avoid the leakage phenomenon of screw holes, the utility model provides a color steel plate roof connection structure.

The technical solution of the present invention is: color steel plate roof connection structure, including roof purlins and color steel plates, and the roof purlins and color steel plates are connected by screws. Waterproof pad, the top of the outer waterproof pad is covered with a layer of composite waterproof material layer; the top of the color steel plate is pasted with a layer of composite material; the thickness of the composite material layer is 4mm, and there are butyl rubber layers from bottom to top , Polyester non-woven fabric layer and metal aluminum foil layer.

The utility model adds a waterproof pad under the self-tapping screw of the waterproof gasket. After fixing with the color steel plate, a layer of waterproof pad is provided on the upper part of the self-tapping screw, and then the color steel roof is covered with a special self-adhesive waterproof coiled material. The waterproof spacer block has strong adhesion, can firmly adhere to color steel plates and screws, block the screw holes, and solve the problem of water seepage in the screw holes.
