Description

Technical Field

[0001] The present application relates to the technical field of building waterproofing, and in particular to a roof waterproofing maintenance structure. Background Art

[0002] TPO waterproofing membrane is a synthetic polymer waterproofing membrane waterproofing product, which is widely used in the overall maintenance of corrugated steel sheets on steel structure roofs. The common method is to directly stick TPO waterproofing membrane on the corrugated steel sheets on the steel structure roofs, or to use high-density insulation board to lay in the trough of the corrugated steel sheet. The high-density insulation board laid in the trough should be as high as the peak of the corrugated steel sheet, and then lay a high-density insulation board on the whole. The TPO waterproofing membrane is laid on top and mechanical construction is used.

[0003] However, the traditional mechanical fixing method is not suitable for all corrugated steel sheets. If TPO waterproofing membrane is laid directly on the corrugated steel sheet, folding and bulging will occur, and the glue is easy to debond. The bulge position will expand and contract due to heat and cold, and will become larger and larger, shortening the service life of the waterproofing membrane. At the same time, it will increase the load on the roof corrugated steel sheet, so that it is necessary to recalculate whether the load of the corrugated steel sheet meets the requirements.

[0032] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] According to some embodiments of the present application, referring to Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of a roof waterproof maintenance structure according to an embodiment of the present application. Figure 2 is a schematic diagram of the structure of the support structure of an embodiment of the present application, Figure 3 The schematic diagram of the structure of the composite plate layer of the embodiment of the present application. The roof waterproof maintenance structure of the embodiment of the present application is arranged on the roof of the building, and includes a glass wool layer 20, a corrugated steel plate layer 30, a plurality of supporting structures 40, a composite plate layer 50 and a waterproof roll material layer 60; the glass wool layer 20 is arranged on the top of the building roof 10; the corrugated steel plate layer 30 is arranged on the top of the glass wool layer 20, and the corrugated steel plate layer 30 is composed of a plurality of corrugated steel plates connected by a bite 31; a plurality of supporting structures 40 are arranged at intervals at the bite 31, and the supporting structures 40 are arranged in an enclosed manner at the bite 31, and are fixedly connected to the bite, for supporting the upper structure of the corrugated steel plate layer 30; the composite plate layer 50 is arranged on the top of the supporting structure 40, and a cavity is formed between the composite plate layer 50 and the corrugated steel plate layer 30, and the cavity here is used to accommodate the supporting structure 40. The waterproof roll material layer 60 is arranged on the top of the composite plate layer 50, and the waterproof roll material layer 60 is composed of a plurality of overlapping waterproof roll materials.

[0034] Specifically, the waterproof coiled material layer 60 is made of TPO flexible coiled material, the composite board layer 50 is composed of two layers of iron sheets 51 with a thickness of 0.6 mm and a rock wool board, and a polyethylene breathable film is laid between the building roof 10 and the glass wool layer 20 .

[0035] The corrugated steel sheet layer 30 will rust and age over time. At the same time, due to the thermal expansion and contraction of the steel sheet, the corrugated steel sheet has a wave peak and will relax at the nodes of the corrugated steel sheet, so water leakage will occur at the nodes. Therefore, the roof is waterproofed by laying a waterproof roll layer 60 on the corrugated steel sheet layer 30. In order to prevent the folding and bulging caused by laying the waterproof roll layer 60 directly on the corrugated steel sheet layer 30, the support structure 40 is enclosed and set at the bite 31 of the corrugated steel sheet layer 30. The support structure 40 is used to support the upper structure composite plate layer 50 of the corrugated steel sheet layer 30. The waterproof roll layer 60 is set on the top of the composite plate layer 50 to ensure the flatness of the waterproof roll layer 60, ensure the tightness of the waterproof roll, and enhance the waterproof effect.

[0036] refer to Figure 2In other embodiments, the support structure 40 includes a support frame 41 and a first screw 42. Two support frames 41 are symmetrically arranged on both sides of each bite 31. The two support frames 41 are enclosed on both sides of the bite 31. The first screw 42 is used to fix the support frame 41 and the bite 31. The support frame 41 includes a connecting portion 43, which is horizontally arranged on the top of the support frame 41 and is used to support the composite board layer 50. The support structure 40 also includes a second screw 44, which is used to fix the composite board layer 50 and the connecting portion 43.

[0037] Two support frames 41 are symmetrically arranged on both sides of each bite 31. The two support frames 41 can enclose the connection of the bite 31. A connecting portion 43 is horizontally arranged on the top of the support frame 41 to ensure that the composite board layer 50 can be laid horizontally in the future, thereby ensuring that the waterproof roll material layer 60 can be laid horizontally. The two support frames 41 at the top of the bite 31 are connected by a fixing member 47; the two support frames 41 at the bottom of the bite 31 are connected by a first screw 42, specifically, the first screw 42 passes through the two support frames 41 and the bite 31, to ensure the stability of the connecting frame.

[0038] like Figure 1 and Figure 2 As shown, Figure 2 Schematic diagram of the structure of the conversion shaft of the embodiment of the present application. The support structure 40 also includes a steel plate bracket 45, one end of which is arranged in the bite 31, and the other end is arranged in the glass wool layer 20, for supporting the support frame 41. The support structure 40 also includes a third screw 46, and a connecting seat 451 is provided at the bottom of the steel plate bracket 45, and the third screw 46 fixes the connecting seat 451 to the glass wool layer 20.

[0039] Specifically, one end of the steel plate bracket 45 is arranged in the bite 31 to provide support force for the corrugated steel plate layer 30. The third screw 46 passes through the connecting seat 451 at the bottom of the steel plate bracket 45 and is fixed in the glass wool layer 20 to provide stable support force for the corrugated steel plate layer 30, which is convenient for the subsequent laying of the composite plate layer 50 and the waterproof membrane layer 60.

[0040] In some embodiments, reference Figure 1 to Figure 2 The two sides of the connecting seat 451 are wedge-shaped. A rubber pad 452 is provided on the bottom surface of the connecting seat 451.

[0041] Specifically, the area of ​​the bottom of the connection seat 451 is smaller than the area of ​​the top of the connection seat 451. The connection seat 451 is arranged in this way, and the connection seat 451 is fixedly connected to the glass wool layer 20, so when a vertical force is generated on the connection seat 451, the glass wool layer 20 will generate resistance to the hypotenuse of the connection seat 451. As a result, the wedge-shaped structures on both sides of the connection seat 451 can be more firmly inserted into the glass wool layer 20, thereby preventing the connection seat 451 from rolling or moving. Because the connection seat 451 is made of metal material, it is easy to produce relative friction with the glass wool layer 20, so a rubber pad 452 is provided on the bottom surface of the connection seat 451, and the rubber pad 452 can increase the friction. Preferably, a plurality of grooves are provided at the bottom of the rubber pad 452 to further increase the contact area between the rubber pad 452 and the glass wool layer 20, thereby increasing the friction between the two, so that the connection seat 451 is more stable.

[0042] In some embodiments, reference Figure 1 , further comprising a fourth screw 70 and a gasket 80, the fourth screw 70 passing through the gasket 80 and the waterproofing membrane layer 60, and passing through the composite board layer 50, for fixing the composite board layer 50 and the waterproofing membrane layer 60. A groove is provided at the top of the gasket 80, and the nail head of the fourth screw 70 is clamped in the groove.

[0043] The fourth screw 70 is used to fix the composite board layer 50 and the waterproof roll material layer 60. The fourth screw 70 is fixedly connected to the building roof 10, so that the waterproof roll material layer 60 is fixed more firmly and meets the design requirements of the roof wind load resistance. The gasket 80 is set to prevent the fourth screw 70 from damaging the waterproof roll material layer 60. Preferably, the length of the fourth screw 70 is greater than the thickness of the composite board layer 50, that is, the fourth screw 70 needs to penetrate the composite board layer 50. Since the waterproof roll material layer 60 is composed of a plurality of overlapping waterproof roll materials, in order to ensure that the surface of the waterproof roll material layer 60 is flat, the gasket 80 is set at the overlap of two waterproof roll materials and is located between the two waterproof roll materials. At the same time, in order to prevent the fourth screw 70 from damaging the upper waterproof roll material, a groove is provided on the top of the gasket 80, and the nail cap of the fourth screw 70 is stuck in the groove, so that the top of the gasket 80 after the fourth screw 70 is inserted is a plane, thereby better protecting the waterproof roll material on the upper layer of the gasket 80. The overlap of two adjacent waterproof roll materials is connected by welding. The welded waterproof membrane has good airtightness at its overlap, which enhances the waterproof effect.

[0044] The following will give a detailed introduction to the working principle of the roof waterproofing repair structure.

[0045] In order to prevent the folding and bulging caused by laying the waterproofing membrane layer 60 directly on the corrugated steel sheet layer 30, the support structure 40 is enclosed and set at the bite 31 of the corrugated steel sheet layer 30. The support structure 40 is used to support the upper structure composite board layer 50 of the corrugated steel sheet layer 30. The waterproofing membrane layer 60 is set on the top of the composite board layer 50 to ensure the flatness of the waterproofing membrane layer 60, ensure the tightness of the waterproofing membrane, and enhance the waterproof effect. Two support frames 41 enclose the connection of the bite 31, and the top of the support frame 41 is horizontally provided with a connecting portion 43 to ensure that the composite board layer 50 can be laid horizontally in the future, thereby ensuring that the waterproofing membrane layer 60 is laid horizontally. The two support frames 41 at the top of the bite 31 are connected by a fixing piece; the two support frames 41 at the bottom of the bite 31 are connected by a first screw 42 to ensure the stability of the connecting frame. Since the waterproofing coiled material layer 60 is composed of a plurality of overlapping waterproofing coiled materials, in order to ensure that the surface of the waterproofing coiled material layer 60 is flat, the gasket 80 is arranged at the overlap of the two waterproofing coiled materials and is located between the two waterproofing coiled materials. At the same time, in order to prevent the fourth screw 70 from damaging the upper waterproofing coiled material, a groove is provided on the top of the gasket 80, and the nail cap of the fourth screw 70 is stuck in the groove, so that the top of the gasket 80 after the fourth screw 70 is inserted is a plane, thereby better protecting the waterproofing coiled material on the upper layer of the gasket 80. The overlap of two adjacent waterproofing coiled materials is connected by welding. The waterproofing coiled material after welding has good airtightness at its overlap, which enhances the waterproofing effect. The present application solves the waterproofing maintenance problem of the bite connection and buckle connection of the corrugated steel sheet of the steel structure roof. It not only ensures the premise of not dismantling the original roof corrugated steel sheet, but also does not increase excessive load, realizes the mechanical fixing method, and meets the problem of mechanically fixing wind load.
