Description

A waterproof treatment method for explosion-proof bolts on thermoplastic polyolefin metal roofs Technical Field

[0001] The invention relates to a waterproof treatment method for explosion-relief bolts on thermoplastic polyolefin metal plates roofs. Background Art

[0002] According to the National Building Design Standard Atlas, "Explosion-Resistant and Explosion-Venting Doors, Windows, Roofs, and Wall Structures," 14J938, the pressure relief portion of the lightweight explosion-venting roof is constructed of lightweight materials. In the event of an accident inside a building, the lightweight pressure-relief roof provides effective pressure relief, minimizing damage to the building's main structure.

[0003] When an exposed single-layer waterproof membrane roof is designed, if an explosion occurs indoors, the presence of the exposed, fully welded, sealed polymer waterproof membrane may cause the explosion-relief bolts to be unable to fall off and the pressure to be released. Summary of the Invention

[0004] In order to solve the defects of the prior art, the present invention provides a waterproof treatment method for explosion-proof bolts on a thermoplastic polyolefin metal plate roof. A thermoplastic polyolefin metal plate is fixed on the top roof layer, and the explosion-proof bolts are passed through the thermoplastic polyolefin metal plate. A thermoplastic polyolefin waterproof sheet is used to cover the portion of the explosion-proof bolt exposed from the thermoplastic polyolefin metal plate, and the thermoplastic polyolefin waterproof sheet is sealed and fixed to the thermoplastic polyolefin metal plate.

[0005] Preferably, the welding strength of the thermoplastic polyolefin waterproof sheet at the explosion-relief bolt is ≥4.0 N / mm.

[0006] Preferably, the thermoplastic polyolefin metal plate is a formed roof outer plate (i.e., a roof fusion tile) formed by extruding and bending a thermoplastic polyolefin metal flat plate through a tile press; the thermoplastic polyolefin metal flat plate is a composite plate formed by bonding an exposed thermoplastic polyolefin waterproof membrane to a galvanized steel plate.

[0007] Preferably, if the thermoplastic polyolefin metal sheet (i.e., roof fusion tile) is connected in the length direction by anchoring, the anchoring end is set on the supporting member and is reliably connected to the supporting member. The anchoring length is not less than 250 mm, and the anchoring part is sealed by hot welding with waterproof membrane.

[0008] Preferably, the length of a single thermoplastic polyolefin metal sheet does not exceed 36 m, and the roof slope is not less than 2%.

[0009] Preferably, the thermoplastic polyolefin waterproof sheet is obtained by cutting a thermoplastic polyolefin waterproof roll.

[0010] Preferably, the thermoplastic polyolefin waterproof sheet is circular.

[0011] Preferably, the thermoplastic polyolefin waterproof sheet is sealed and fixedly bonded to the thermoplastic polyolefin metal plate by hot air welding.

[0012] Preferably, the roof is fixed on the purlin, and a thermal insulation layer, a vapor barrier layer, and a steel mesh are fixed in sequence from top to bottom between the thermoplastic polyolefin metal plate and the purlin.

[0013] Preferably, a steel mesh is laid on the purlin; a vapor barrier layer is laid on the steel mesh; a thermal insulation layer is laid on the vapor barrier layer; a thermoplastic polyolefin metal plate is laid on the thermal insulation layer, and the long sides of the thermoplastic polyolefin metal plate are anchored and the short sides are hot-welded; explosion-relief bolts are installed on the thermoplastic polyolefin metal plate, and the explosion-relief bolts pass through the thermoplastic polyolefin metal plate; a thermoplastic polyolefin waterproof sheet is used to cover the portion of the explosion-relief bolt exposed from the thermoplastic polyolefin metal plate, and the thermoplastic polyolefin waterproof sheet is sealed and fixed to the thermoplastic polyolefin metal plate by hot air welding.

[0014] The advantages and beneficial effects of the present invention are: providing a waterproof treatment method for explosion-proof bolts on thermoplastic polyolefin metal plate roofs, which uses a thermoplastic polyolefin waterproof sheet to cover the explosion-proof bolts, will not hinder the pressure relief of the explosion-proof bolts, and can solve the engineering quality problem of single-layer waterproof membrane roofing systems that are not conducive to explosion relief.
