Description

Technical Field

[0001] The utility model belongs to the technical field of roof connection, and in particular relates to a multifunctional installation component and a prefabricated fastener suitable for a roof system. Background Art

[0002] Existing roofs such as conventional steel-plastic composite panels (PVC / TPO polymer coils and steel plates laminated together, hereinafter referred to as composite panels), fusion tiles, plastic steel tiles, etc., need to penetrate the roof with screws during roof construction and installation, and connect and fix with the supporting structure (purlin structure) of the roof system. Figure 1 As shown. Since the screws damage and penetrate the roof, it may cause water leakage. Therefore, each screw needs to be covered with a patch of the same material as the roof surface to ensure waterproof performance. The installation process of this roof system not only uses a large number of screws and waterproof patches, but also requires a lot of time and manpower. Due to the different technical capabilities of workers, there is also a risk of construction quality. At the same time, in order to meet the wind-resistant requirements of the roof system, the spacing of the screws is relatively dense. When designing and installing the structural load modeling of the roof, it will be considered to bend the plate into more peaks and troughs to enhance the strength of the roof. Therefore, the current roof board rate is relatively low. Taking the composite board as an example, that is, a 1m flat plate, the more bends, the lower the width of the finished board will be, and the more composite boards will be used in the project, resulting in an increase in material costs and a longer construction period.

[0003] In addition, when photovoltaic and other roof extension equipment is added to the roof system at a later stage, it is also necessary to use separate connectors to fix the product, that is, to meet the usage requirements through secondary construction, which may cause hidden dangers to the roof's waterproof performance, life and maintenance.

[0055] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0057] Embodiment 1:

[0058] A multifunctional installation component suitable for a roof system is used to connect two or more components to be installed. In this embodiment: the installation component is used to connect a roof, a roof support structure and a roof extension device.

[0059] The mounting assembly includes a fastening body 1 and a connecting member 2. The fastening body 1 and the connecting member 2 are described in detail below.

[0060] like Figure 2a As shown: a connection hole 100 is provided on the fastening body 1, and a connection portion 101 is provided on the outer surface of the fastening body 1, and it is preferred that the fastening body and the connection hole 100 are coaxial. That is, the fastening body 1 can be connected to the roof and the roof supporting structure (purlin structure) through its connection portion 101.

[0061] In one implementation of this embodiment: the fastening body 1 includes a cylindrical section 10 and a tapered section 11 arranged in sequence along its length direction, and the outer diameter of the tapered section 11 gradually decreases from the end close to the cylindrical section 10 to the end away from the cylindrical section 10. Among them: the connecting hole 100 is opened on the end surface of one end of the cylindrical section 10, and it is preferred that the cylindrical section 10 and the connecting hole 100 are coaxial, and the connecting portion 101 is arranged on the outer surface of the cylindrical section 10; the outer surface of the tapered section 11 is provided with the connecting portion 101 or is a smooth surface, Figure 2a In the example, the conical section 11 takes a smooth surface as an example; Figure 2b In the embodiment, the conical section 11 is also provided with a connecting portion 101 .

[0062] In another implementation of this embodiment: the fastening body 1 has a limiting boss 12 protruding from its outer surface, the limiting boss 12 is located at one end of the fastening body 1 where the connecting hole 100 is opened, and it is preferred that the fastening body 1 and the limiting boss 12 are coaxial. Figure 3The limiting boss 12 is used to ensure that a reminder is given when the fastening body 1 is installed in place, to prevent construction workers from over-installing, damaging the roof system structure, and affecting safety and waterproof performance; at the same time, it also makes the connection between the roof and the roof support structure tighter, reducing the risk of water leakage at the connection between the fastening body 1 and the roof and the roof support structure.

[0063] The connecting hole 100 is a threaded hole, which is coaxially opened on the end face of one end of the fastening body 1. The connecting hole 100 is preferably a hole with one end open and the other end closed, that is, a blind hole; of course, the connecting hole 100 can also be a through hole that penetrates the fastening body 1.

[0064] The connection part 101 is a threaded connection part, that is, an external thread, preferably a coarse thread. The corresponding standard specification requires that the design tensile force value of the screw is 600N, and the actual test value is generally about 2KN. The coarse thread designed and used in this embodiment has an actual force value of not less than 10KN. Since the tensile performance of the fastening body 1 is higher and stronger, in theory, the installation arrangement spacing of the fastening body 1 can be reduced. It is estimated that the number of fastening bodies 1 that can be reduced is not less than 2 / 3, which reduces the materials for roof construction and reduces the comprehensive cost of installation. In addition, due to the reduction in the number of openings, the risk of water leakage is reduced, and the roof support structure is also protected.

[0065] In this way, the fastening body 1 can perform self-drilling on the roof and the roof supporting structure in sequence through the conical section 11 and the columnar section 10, and after entering the roof and the roof supporting structure, the two can be connected and fastened through the thread of the connecting part 101.

[0066] The fastening bodies 1 are all metal prefabricated parts, that is, they are industrially produced and processed in the factory and assembled on site, which reduces the difficulty of operation and improves the construction efficiency. The industrial production in the factory can ensure the quality and efficient supply of the fastening bodies 1. The high degree of integration reduces the on-site assembly process and requirements. Only hole drilling, installation and welding are required on site. The installation is simple, which ensures the construction efficiency and quality.

[0067] like Figure 4 , 5 As shown: the connecting member 2 includes a connecting body 20, a waterproof structure 21 connected to one end of the connecting body 20, and a mounting hole 200 is provided at one end of the connecting body 20 connected to the waterproof structure 21. The connecting body 20 can be matched with the connecting hole 100 to fix the connecting member 2 on the fastening body 1. Figure 7 That is, the connector 2 is connected to the fastening body 1 through the connecting body 20 on one hand, and is used to connect the roof extension equipment through the mounting hole 200 on the other hand, thereby reducing the adverse effects of secondary roof construction.

[0068] In one implementation of this embodiment: the outer surface of the connecting body 20 is provided with an external thread 201, and the mounting hole 200 is a threaded hole, that is, the connecting body 20 is a structure of internal and external double threads, and the external thread 201 matches the threaded hole of the connecting hole 100 of the fastening body 1, and is connected and fixed by rotation and locking; the mounting hole 200 can be matched with a screw within φ12mm for rotation and locking according to the use requirements, so as to cooperate with the installation application of the roof extension equipment, such as Figure 6 The connecting body 20 is a metal member, such as aluminum.

[0069] In addition, the mounting hole 200 is coaxially opened on the end face of one end of the connecting body 20 . The mounting hole 200 is preferably a hole with one end open and the other end closed, that is, a blind hole. Of course, the mounting hole 200 can also be a through hole that penetrates the connecting body 20 .

[0070] In another implementation of this embodiment: the waterproof structure 21 includes a pressing plate 210 and a waterproof board 211, and the pressing plate 210 is arranged on the upper surface and / or the lower surface of the waterproof board 211, and the outer diameter of the waterproof board 211 is larger than the outer diameter of the pressing plate 210. During construction and installation, the threads on the outer peripheral surface of the connecting body 20 may scratch or puncture the waterproof board 211. By using the pressing plate 210 on the upper surface of the waterproof board 211, the damage of the screw to the waterproof board 211 can be avoided, thereby ensuring the overall waterproof performance and life of the roof system. Preferably, the pressing plate 210 is respectively arranged on the upper surface and the lower surface of the waterproof board 211, and the double-sided support of the pressing plate 210 can cover a larger range of waterproof area, and the wind resistance performance is also better.

[0071] Among them: the pressure plate 210 is a metal coated plate; the waterproof plate 211 is a waterproof coiled material. The metal coated plate can provide better supporting and protective performance, and has higher structural strength, which can prevent the metal coated plate from bending and deforming when subjected to force; the metal coated plate can also protect the waterproof plate; the metal coated plate and the waterproof coiled material are laminated to ensure the sealing and impermeability between the two different materials.

[0072] In another implementation of this embodiment: a through hole 212 is provided on the waterproof structure 21, and one end of the connecting body 20 is fixed in the through hole 212 of the waterproof structure 21, and the connecting body 20 and the waterproof structure 21 can be directly connected through the through hole 212, such as welding the two at the through hole 212. Preferably, the waterproof structure 21 and the through hole 212 are coaxially arranged, so that the connecting body 20 and the waterproof structure 21 are also coaxially arranged.

[0073] One end of the connecting body 20 (the end with the mounting hole 200) is flush with the outer end surface of the through hole 212, and in the figure, is flush with the upper surface of the pressure plate 210 above the waterproof board 211. In this way, after the connecting member 2 is fixed to the fastening body 1, the waterproof structure 21 (the upper surface of the pressure plate 210 above the waterproof board 211) is almost flush with the roof, that is, the connecting body 20 and the waterproof structure 21 form a sunken structure, and the entire connecting member 2 has no part protruding from the waterproof structure 21, which will not affect the original roof drainage design, and will not cause water flow obstruction and water accumulation at the protruding part; during operation and maintenance, local stress concentration will not be caused by stepping on the protruding part, causing damage to the connecting member and the roof system; in addition, it also brings convenience to the construction, and the welding of the waterproof structure 21 and the roof waterproof material can be completed without moving, and there will be no situation that affects or hinders the construction tools; and the aesthetics is also higher. Of course, it is also possible for one end of the connecting body 20 to be slightly higher than the through hole 212, or slightly lower than the through hole 212.

[0074] In another implementation of this embodiment: the connection body 20 has a limiting boss 202 protruding from its outer surface, and the lower surface of the waterproof structure 21 abuts against the upper surface of the limiting boss 202. Specifically: the lower surface of the pressing plate 210 below the waterproof plate 211 in the waterproof structure 21 abuts against the upper surface of the limiting boss 202. More specifically, the pressing plate 210 forms a lower extension 2100 downward, and abuts against the upper surface of the limiting boss 202 through the lower extension 2100. The limiting boss 202 can support and limit the waterproof structure 21, and the two can be connected by laser full welding to ensure the air tightness and impermeability of the connection; at the same time, the limiting boss 202 also ensures the stability of welding, and can also have a positioning effect on the waterproof structure 21, ensuring the flatness and aesthetics of the visible surface of the connector 2.

[0075] The connecting parts 2 are all prefabricated parts, and the connecting body 20 and the waterproof structure 21 are integrated into one part, that is, they are industrially produced and processed in the factory to ensure the sealing performance of the product, and assembled on site, which reduces the difficulty of operation and improves the construction efficiency; the factory's industrial production can ensure the quality and efficient supply of the connecting parts 2, and the high degree of integration reduces the on-site assembly process and requirements. Only hole drilling, installation and welding are required on site, and the installation is simple, which not only ensures the construction efficiency and quality, but also improves the aesthetics and waterproofness of the construction node parts.

[0076] In addition, the connection assembly may further include a plug, which is used to block the mounting hole 200 when the mounting hole 200 is not connected to the roof epitaxial device. When the mounting hole 200 is not connected to the roof epitaxial device, the plug is set in the mounting hole 200 to block the mounting hole 200; when the mounting hole 200 needs to be connected to the roof epitaxial device, the plug can be removed.
