Technical Field

[0001] The utility model relates to the field of roof waterproofing, and particularly to a TPO single-layer roof system. Background Art

[0002] As disclosed in the Chinese utility model patent publication No. CN 210395893 U, a waterproof joint node between a steel structure parapet and a TPO roof is disclosed, which relates to the field of building structures. A steel deck is installed on the top of a roof purlin. A PE film, a rock wool layer and a roof TPO waterproofing membrane are sequentially laid on the top of the steel deck from bottom to top and are fixedly connected by U-shaped screws; a wall purlin is installed on a parapet column. A parapet TPO membrane is laid on the top of the parapet column, and its outer side and inner side are respectively connected and fixed to the outer side surface and the inner side surface of the parapet column by U-shaped screws. The joint of the parapet TPO membrane and the roof TPO waterproofing membrane is fully welded by hot air welding. The disadvantage of fixing by screws is that it is easy to damage the waterproofing membrane and affect the waterproofing effect. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a TPO single-layer roof system, which can fix a single-layer TPO waterproofing membrane without punching holes in the waterproofing membrane, and is also beneficial to reducing the thickness of the overall functional layer of the roof.

[0004] To solve the above problems, a TPO single-layer roof system is adopted, which includes:

[0005] Purlins, with multiple purlins laid at intervals;

[0006] A profiled steel sheet base layer, which is laid on the purlins;

[0007] A vapor barrier layer, which is laid on the profiled steel sheet base layer;

[0008] A rock wool board insulation layer, which is laid on the vapor barrier layer;

[0009] Metal gaskets, which are laid at intervals on the rock wool board insulation layer, and an asphalt coating is provided on its upper surface;

[0010] Heat insulation sleeves, which are inserted through the metal gaskets, with flanges provided at intervals thereon closely attached to the upper and lower sides of the metal gaskets. A sunken hole is provided in the middle thereof, and a conical sleeve is fixedly connected to its lower side. Vertical gaps are distributed on the conical sleeve, and the vertical gaps extend to the bottom end of the conical sleeve, dividing the conical sleeve into multiple parts;

[0011] Screws, which are threadedly connected in the sunken holes and penetrate into the rock wool board insulation layer;

[0012] A TPO waterproofing membrane, which is laid on the rock wool board insulation layer and covers the metal gaskets.

[0013] With this structure, the electromagnetic heater is used to generate heat through the TPO waterproofing membrane to heat the metal gasket under the TPO waterproofing membrane, melt the asphalt coating on the gasket, so that it can be bonded with the base layer of the TPO waterproofing membrane, thereby achieving non-perforation fixation;

[0014] The conical sleeve is advantageous for first inserting into the thermal insulation layer of the rock wool board, and then the screw is drilled into the thermal insulation sleeve by an electric screwdriver. After the screw is drilled into the conical sleeve, the separated parts of the conical sleeve can be stretched open to form barbs that are inserted into the thermal insulation layer of the rock wool board, thereby achieving positioning.

[0015] As a further improvement of the present invention, the metal gasket is a copper gasket.

[0016] With this structure, the copper gasket is more likely to conduct heat.

[0017] As a further improvement of the present invention, the upper surface of the metal gasket is corrugated.

[0018] With such a structure, the corrugated surface coating area is larger, and after heating, the bonding area with the TPO waterproof membrane is larger, which is conducive to improving the degree of fixation.

[0019] As a further improvement of the utility model, the heat insulating sleeve is closely attached to the flange on the lower side of the metal gasket and extends to the edge of the metal gasket, separating the metal gasket from the rock wool board insulation layer.

[0020] Such a structure can be adopted to prevent the metal gasket from contacting with the thermal insulation layer of the rock wool board when heated, thereby avoiding damage to the thermal insulation layer of the rock wool board.

[0021] As a further improvement of the present invention, the TPO waterproofing membrane is 1.8 mm.

[0022] As a further improvement of the present invention, the rock wool board insulation layer adopts 100mm rock wool board.

[0023] As a further improvement of the utility model, the heat insulating sleeve is fixed on the sleeve in close contact with the flange on the lower side of the metal gasket, and is threadedly connected to the heat insulating sleeve through the sleeve, and the metal gasket is tightened.

[0024] With such a structure, the metal gasket and the heat insulation sleeve are tightened one step in advance to prevent the heat insulation sleeve from rotating when the screw is drilled in, thereby affecting the screw from entering the heat insulation sleeve.

[0025] The utility model avoids the need to punch holes in the waterproofing coiled material, can fix the single-layer TPO waterproofing coiled material, and is also beneficial to reducing the thickness of the overall functional layer of the roof. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The heat-insulating sleeve 6 passes through the metal gasket 5, and flanges 61 are arranged on the heat-insulating sleeve 6 to be close to the upper and lower sides of the metal gasket 5. A countersunk hole 62 is arranged in the middle, and a conical sleeve 63 is fixedly connected to the lower side. The conical sleeve 63 is provided with vertical gaps 64, which extend to the bottom end of the conical sleeve 63, and divide the conical sleeve 63 into multiple parts.

[0040] The screw 7 is threadedly connected in the countersunk hole 62 and penetrates into the rock wool board insulation layer 4;

[0041] The TPO waterproofing membrane 8 is laid on the rock wool insulation layer 4 and covers the metal gasket 5 .

[0042] With such a structure, an electromagnetic heater is used to generate heat through the TPO waterproofing membrane 8 to heat the metal gasket 5 under the TPO waterproofing membrane 8, so as to melt the asphalt coating on the gasket so that it can be bonded to the base layer of the TPO waterproofing membrane 8, thereby achieving non-perforated fixation;

[0043] The conical sleeve 63 is advantageously inserted into the thermal insulation layer 4 of the rock wool board first, and the screw 7 is drilled into the thermal insulation sleeve 6 by an electric screwdriver. After the screw 7 is drilled into the conical sleeve 63, the separated part of the conical sleeve 63 can be stretched open to form barbs that are inserted into the thermal insulation layer 4 of the rock wool board, thereby achieving positioning.

[0044] In this embodiment, the metal gasket 5 is a copper gasket.

[0045] With this structure, the copper gasket is more likely to conduct heat.
