Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a non-perforated installation structure of a TPO waterproof coiled material. Background Art

[0002] Thermoplastic polyolefin waterproofing membrane (TPO), the North American roof waterproofing master, has a service life of over 25 years. It is known for its low-temperature flexibility and weather resistance, and is resistant to root puncture. It is widely used in steel structure factories, color steel roofs, large commercial and civil building roofs that have special requirements for waterproofing. Most of the current TPO waterproofing membranes are installed through non-perforated fixings. The existing non-perforated fixings include welded steel sheets. The welded steel sheets are connected to the lower corrugated steel plates or building purlins and other structures through connecting bolts that penetrate the insulation structure layer and other structures. The welded steel sheets are heated by an electromagnetic induction welding machine and welded to the TPO waterproofing membrane. After cooling, a high-strength connection node is formed, which can well resist the wind-lifting effect. In addition, the TPO waterproofing membrane is not perforated and damaged, and has good integrity, which can achieve a good waterproofing effect.

[0003] However, since the insulation structure layer between the corrugated steel plate and the TPO waterproofing membrane is generally made of lightweight materials, the texture is relatively soft and elastic. When installing the connecting bolts, it is easy to cause the center of the welded steel sheet to sag due to the difficulty in controlling the tightening force, which causes the welding surface of the welded steel sheet and the TPO waterproofing membrane to tilt, making the contact between the welded steel sheet and the TPO waterproofing membrane uneven, and the bonding after welding is not strong, thus affecting its welding strength. At the same time, the two ends of the connecting bolt are connected to the welding steel sheet and the corrugated steel plate respectively, and the heat will be directly transferred to the outside through the connecting bolt, thereby affecting the insulation performance of the entire roof structure. Furthermore, due to the soft nature of the insulation structure layer, its lateral strength is poor. If it only relies on the connection of the connecting bolts, the welding steel sheet will drive the connecting bolts to move laterally under the effect of the wind lifting effect, which is easy to cause fatigue damage to the relevant connection nodes, thereby affecting the service life.

[0020] Example: See Figures 1 to 3 A non-perforated installation structure of a TPO waterproof membrane comprises, from bottom to top, a corrugated steel plate 1, a thermal insulation structure layer 2 and a TPO waterproof layer 3, wherein the TPO waterproof layer 3 is connected to the corrugated steel plate 1 through a non-perforated fixing part, wherein the non-perforated fixing part comprises a circular welding steel sheet 4 arranged between the TPO waterproof layer 3 and the thermal insulation structure layer 2, the welding steel sheet 4 is connected to the corrugated steel plate 1 through a connecting bolt 5 penetrating the thermal insulation structure layer 2, and the TPO waterproof layer 3 is welded to the welding steel sheet 4; specifically, the welding steel sheet 4 is formed with an upwardly protruding welding ring 402, so that an installation groove is formed at the center of the circle, and the lower side of the TPO waterproof layer 3 is welded to the upper side of the welding ring 402.

[0021] It also includes a heat-insulating support member 6 that passes through the heat-insulating structure layer 2. The heat-insulating support member 6 is a cylindrical structure that is vertically arranged and made of heat-insulating material. Its upper end is connected to the welded steel sheet 4, and its lower end is connected to the corrugated steel plate 1 through self-tapping screws. A connecting hole 7 that passes through both ends is opened at its axis. A heat-insulating sleeve 8 made of heat-insulating material is sleeved in the connecting hole 7. The upper end of the heat-insulating sleeve 8 is connected to the welded steel sheet 4, and the lower end extends to the middle of the support member. The lower end of the connecting bolt 5 passes through the heat-insulating sleeve 8 and the connecting hole 7 and is connected to the corrugated steel plate 1, and its upper end is connected to the lower end of the heat-insulating sleeve 8. Specifically, the heat-insulating support member 6 is a wooden structure, and the heat-insulating sleeve 8 is made of high-strength plastic or composite material, so that it has good heat-insulating performance.

[0022] The upper end of the thermal insulation sleeve 8 extends outward to form a connecting cap 801, and the lower end is provided with a base plate, and a through hole is opened on the base plate. The diameter of the through hole is smaller than the inner diameter of the thermal insulation sleeve 8, so that the base plate forms a supporting platform structure 802; correspondingly, a through hole is opened at the center of the welding steel sheet 4, and the lower end of the thermal insulation sleeve 8 passes through the through hole, and its connecting cap 801 is fit-connected to the upper side of the welding steel sheet 4; the connecting bolt 5 has a screw and a nut, and its screw passes through the through hole, and its nut is fit-connected to the upper side of the supporting platform structure 802.

[0023] The connecting hole 7 includes a first hole section and a second hole section, wherein the diameter of the first hole section is larger than the diameter of the second hole section and matches the outer diameter of the heat insulating sleeve 8, and the diameter of the second hole section is consistent with the diameter of the perforation, so that a step structure 701 is formed at the connection between the first hole section and the second hole section, wherein the length of the first hole section matches the length of the heat insulating sleeve 8, and when the lower end of the heat insulating sleeve 8 abuts against the step structure 701, its connecting cap 801 is fitted and connected with the upper side of the welding steel sheet 4. In this way, the pressure of the nut of the connecting bolt 5 is jointly borne by the step structure 701 and the supporting platform structure 802 of the heat insulating sleeve 8, thereby improving the connection strength. At the same time, the first hole section of the connecting hole 7 matches the outer diameter of the heat insulating sleeve 8, so that the heat insulating sleeve 8 can be better bound and restricted, so that it has better strength, prevents it from being damaged under the action of tension and lateral force, and improves its service life. Through this installation structure, the heat transfer between the connecting bolt 5 and the welding steel sheet 4 is completely disconnected, thereby improving the thermal insulation performance of the roof structure.

[0024] Furthermore, in order to improve the lateral stability of the welded steel sheet 4, a plurality of concentric annular grooves are provided at the upper end of the support member, and correspondingly, a plurality of concentric annular ridges 401 are formed on the lower side of the welded steel sheet 4, and the ridges 401 are embedded in the grooves, wherein the cross-sections of the grooves and the ridges 401 are rectangular, isosceles trapezoidal, triangular or semicircular, thereby limiting the lateral slippage of the welded steel sheet 4, and then the lateral force is resisted by the support member, thereby ensuring its stability and strength and improving the use effect.

[0025] The utility model supports the welded steel sheet by adopting a heat-insulating support member. When installing the connecting bolts, the welded steel sheet will not be sunken due to the deformation of the thermal insulation structure layer, thereby ensuring the structural stability of the welded steel sheet and the welding quality. At the same time, a heat-insulating sleeve structure is adopted to prevent the connecting bolts from being directly connected to the welded steel sheet, thereby disconnecting the thermal bridge between the corrugated steel plate and the welded steel sheet, thereby improving the overall thermal insulation performance of the roof structure. The support member is fixed on the corrugated steel plate and has a large size, which can assist the connecting bolts in improving the overall lateral force performance of the installation structure, thereby improving the overall strength of the installation structure and extending its service life.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the utility model without departing from the purpose and scope of the technical solution of the utility model should be included in the scope of the claims of the utility model.
