Abstract
The invention relates to an upright steel roof waterproof structure and a construction method thereof. The upright steel roof waterproof structure comprises a compressed steel sheet fixedly connectedwith a roof purline, wherein a steam insulation layer, a heat preservation and insulation layer and a waterproof layer are sequentially laid on the compressed steel sheet; surface layer splicing seamsof the heat preservation and insulation layer are bonded through adopting macromolecular waterproof adhesive tapes; the waterproof layer is made of PVC waterproof coiled materials, wherein every twoadjacent PVC waterproof coiled materials are in lap joint, the PVC waterproof coiled materials at the bottoms of the lap joint positions are fixedly connected with the compressed steel sheet through screws, the PVC waterproof coiled materials at the tops of the lap joint positions cover the screws, and the edges of the PVC waterproof coiled materials are welded through hot air. According to the upright steel roof waterproof structure and the construction method thereof, by means of the compressed steel sheet, the steam insulation layer, the heat preservation and insulation layer and the waterproof layer, waterproof and heat preservation effects of a roof are improved; and meanwhile, a paving method combining a border adhibiting method with mechanical fixing is adopted to cooperate with theapplication of the macromolecular waterproof adhesive tapes, so that the waterproof quality of the whole roof is ensured.
Description
Technical field [0001] The invention relates to the field of building construction, in particular to an upright steel roof waterproof structure and a construction method thereof. Background technique [0002] The roof is the enclosure and load-bearing structure that covers the uppermost layer of the house. One of its main functions is to protect against wind and rain, as well as to prevent rain and sun. Therefore, the roof waterproof and thermal insulation are particularly important. At present, most of the roof structures of existing waterproof and thermal insulation layers in our country adopt an inverted structure, that is, the waterproof layer is placed under the thermal insulation layer. However, once the insulation layer absorbs too much water, the waterproof layer will be in a state of standing water for a long time. The effect will be difficult to guarantee. [0003] Therefore, how to provide an upright steel roof waterproof structure and a construction method that can im...
