Abstract
Description
Technical Field
[0001] This application relates to the field of waterproof structural technology, and in particular to a prefabricated steel structure roof splicing and locking waterproof system. Background Technology
[0002] Modular container houses, also known as container mobile houses (container houses), or container homes, are houses with doors and windows that are modified from shipping containers. They are constructed with steel structures, making them not only sturdy and durable with a long service life, but also easy to assemble, disassemble, and transport.
[0003] However, when multiple steel structure boxes are assembled together, through cracks can easily appear in the roof, or after prolonged occupancy, misalignment can occur at the joints, affecting not only the sealing performance but also potential leaks. Traditional steel structure boxes are mostly connected using bolts and other fasteners, and waterproofing is limited to sealing gaskets at the joints, resulting in poor waterproofing effectiveness.
[0004] Therefore, this application provides a prefabricated steel structure roof splicing and locking waterproofing system, which can not only increase the tightness of the connection at the splicing of the steel structure box and reduce misalignment, but also improve the waterproofing performance. Utility Model Content
[0005] The purpose of this application is to address the problems existing in the prior art by proposing a prefabricated steel structure roof splicing and locking waterproofing system.
[0006] To achieve the above objectives, this application adopts the following technical solution:
[0007] The prefabricated steel structure roof splicing and locking waterproofing system includes a splicing and locking system installed at the splicing of two adjacent roof panels. On both sides of the splicing and locking system, there are long strip tenons installed on the two adjacent roof panels. Long strip mortises are inserted into the tenons. A waterproof layer is sandwiched between the tenon and the mortise insertion surface. The upper ends of the two adjacent mortises are together covered with a ∩-shaped waterproof cover plate. The waterproof cover plate is fastened to the roof panel by an adjustable lock.
[0008] The adjusting latch includes a retaining shaft, a U-shaped buckle, an adjusting nut, and a retaining edge.
[0009] The clip is inserted into the side wall of the waterproof cover plate. Both ends of the clip have insertion holes. The two cantilever arms of the U-shaped buckle pass through the insertion holes on the corresponding sides, and the upper and lower ends of the insertion holes on the two cantilever arms are screwed with adjusting nuts. The buckle edge is installed on the roof panel, and the U-shaped buckle is abutted against the buckle edge.
[0010] Preferably, the splicing and locking system includes angle steel keels welded and fixed to the upper edge of two adjacent roof panels, with the vertical surfaces of the two angle steel keels touching and fastened together by fasteners.
[0011] Preferably, the surface steel plate of the roof panel has a vertical folded edge, which is attached to the outer wall of the opposite side of the adjacent tenon. The clip is inserted into the side wall of the waterproof cover plate, and the buckle is installed on the folded edge.
[0012] Preferably, the bottom end of the horizontal part of the buckle is provided with a groove that cooperates with the U-shaped buckle.
[0013] Preferably, the waterproof cover is made of a steel plate with a thickness of 2mm.
[0014] Preferably, the tenon is fastened to the roof panel by bolts or welded.
[0015] Compared with existing technologies, this application provides a prefabricated steel structure roof splicing and locking waterproofing system, which has the following advantages:
[0016] 1. In use, the mortise is inserted into the tenon to form a mortise and tenon structure; then, the waterproof cover is placed over the two tenons by adjusting the locking buckle. This, combined with the existing splicing and locking system, provides secondary tightening, improving the tightness of the splices between roof panels and reducing the probability of misalignment at the roof panel joints. Since the roof panel splices are located inside the mortise and tenon structure, the contact area between the tenon and the mortise is bent, reducing the probability of water seepage and thus improving waterproof performance.
[0017] 2. By adjusting the locking mechanism, not only can the waterproof cover plate and the roof panel be securely connected, increasing the tightness of the connection between adjacent roof panels, but there is also room for expansion and contraction, which can adjust the distance between the roof panel and the waterproof cover plate.
[0018] 3. A waterproof layer is sandwiched between the tenon and the mortise joint surface, further improving the waterproof performance.
[0019] Other advantages, objectives and features of this application will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this application.

[0029] The following will refer to the appendices in the embodiments of this application. Figure 1-8 The technical solutions in the embodiments of this application are clearly and completely described. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0030] Example 1: In order to solve the problems existing in the prior art, this example provides a prefabricated steel structure roof splicing and locking waterproof system, including a splicing and locking system set at the splicing of two adjacent roof panels 1. On both sides of the splicing and locking system, there are long strip tenons 3 installed on the two adjacent roof panels 1. Long strip mortises 4 are inserted into the tenons 3. A waterproof layer is sandwiched between the insertion surfaces of the tenons 3 and the mortises 4. The upper ends of the two adjacent mortises 4 are together inverted with a ∩-shaped waterproof cover plate 5. The waterproof cover plate 5 is fastened to the roof panel 1 by an adjustable lock.
[0031] The adjusting latch includes a retaining shaft 6, a U-shaped buckle 7, an adjusting nut 12, and a retaining edge 8.
[0032] The clip 6 is inserted into the side wall of the waterproof cover plate 5. Both ends of the clip 6 are provided with insertion holes. The two cantilever arms of the U-shaped buckle 7 pass through the insertion holes on the corresponding sides, and the two cantilever arms are screwed with adjusting nuts 12 at the upper and lower ends of the insertion holes. The buckle edge 8 is installed on the roof panel 1, and the U-shaped buckle 7 is abutted against the buckle edge 8.
[0033] Principle details of this embodiment:
[0034] The prefabricated steel structure roof is a box-type structure assembled from steel materials through welding or fasteners, including wall panels and roof panels 1. Roof panels 1 are formed by high-pressure bonding of an exterior steel sheet 101, a steel mesh roof joists 102, a roof insulation board 103, and an interior light base board 104 using a specialized press. The pressed panels are then fitted with a frame joists 105 around their perimeter using bolts and other fasteners, thus forming an integrated metal insulation panel. Roof panels 1 and wall panels are reliably joined together using mortise and tenon joints, forming a box-type load-bearing system. The box can also be divided into multiple components for on-site assembly, which not only facilitates transportation and reduces transportation costs due to its small size but also allows for customized services to meet different size requirements.
[0035] The prefabricated steel structure roof splicing and locking waterproofing system includes a splicing and locking system installed at the joint of two adjacent roof panels 1, which locks the two adjacent roof panels 1 together. On both sides of the splicing and locking system, there are elongated tenons 3, the length of which is the same as the perimeter of the roof panel 1. Elongated mortises 4 are inserted into the tenons 3, the length of which is the same as the length of the tenons 3. A ∩-shaped waterproof cover plate 5 is inverted and fastened to the upper end of the two adjacent mortises 4. The inner width of the waterproof cover plate 5 is the same as the distance between the opposite sides of the two mortises 4, and its length is the same as the length of the mortises 4 and the tenons 3. Multiple adjustable latches are provided between the waterproof cover plate 5 and the roof panel 1 along the length direction, and the waterproof cover plate 5 and the roof panel 1 are securely connected by these adjustable latches.
[0036] The waterproof cover plate 5 has multiple inserts spaced along its length on its sidewall, each insert holding a retaining pin 6 for insertion and installation on the sidewall of the waterproof cover plate 5. Both ends of the retaining pin 6 have through holes, and the two cantilever arms of the U-shaped buckle 7 pass through the corresponding holes. Both cantilever arms of the U-shaped buckle 7 are threaded, and two adjusting nuts 12 are screwed onto each cantilever arm at intervals. The two adjusting nuts 12 abut against the upper and lower ends of the holes in the retaining pin 6, respectively.
[0037] The roof panel 1 is fixedly installed with snap edges 8 that correspond one-to-one with the brackets, and the two cantilevered connecting parts of the U-shaped buckle 7 abut against the snap edges 8. The height between the snap edges 8 and the surface of the roof panel 1 is greater than the length of the cantilever of the U-shaped buckle 7 passing through the insertion hole, leaving space for the installation of the U-shaped buckle 7.
[0038] Based on the above technical solution:
[0039] In use, the mortise 4 is inserted into the tenon 3 to form a mortise and tenon structure; then the waterproof cover 5 is fastened, and the bracket is aligned with the buckle edge 8. First, the retaining pin 6 is inserted into the bracket, with both ends of the retaining pin 6 protruding from the sides of the insertion. Then, an adjusting nut 12 is screwed onto each of the two cantilever arms of the U-shaped buckle 7, and the cantilever arm of the U-shaped buckle 7 is inserted into the insertion hole from below the buckle edge 8 and extends out of the insertion hole. Finally, another adjusting nut 12 is screwed onto the cantilever arm of the U-shaped buckle 7. By turning the two adjusting nuts 12, the position of the U-shaped buckle 7 is adjusted so that the U-shaped buckle 7 is tightly fastened to the buckle edge 8. This not only achieves a tight connection between the waterproof cover 5 and the roof panel 1, increasing the tightness of the connection between adjacent roof panels 1, but also provides room for expansion and contraction, allowing adjustment of the distance between the roof panel 1 and the waterproof cover 5.
[0040] After the waterproof cover plate 5 is placed over the two tenons 3, the two tenons 3 are tightened and fixed. Then, it is used in conjunction with the existing splicing and locking system for secondary tightening, which improves the splicing tightness between the roof panels 1 and reduces the probability of misalignment at the splicing of the roof panels 1. Since the splicing of the roof panels 1 is located inside the mortise and tenon structure, the contact part between the tenon 3 and the mortise 4 is bent, which reduces the probability of water seepage and thus improves the waterproof performance.
[0041] The tenon 3 and the mortise 4 are fitted with a waterproof layer, which further improves the waterproof performance.
[0042] Example 2, a further embodiment of this solution, provides a specific splicing and locking system structure: the splicing and locking system includes angle steel keels 10 welded and fixed to the upper end face sides of two adjacent roof panels 1, the two angle steel keels 10 are vertically attached and fastened together by fasteners.
[0043] Principle details of this embodiment:
[0044] The splicing and locking system includes angle steel keel 10. The angle steel keel 10 is welded and fixed to the upper end face of the roof panel 1. The vertical surfaces of the angle steel keels 10 on two adjacent roof panels 1 are fitted together, and multiple through holes are provided at intervals along the length of the vertical surface of the angle steel keel. Splicing bolts 11 are inserted into the through holes, and splicing nuts are screwed onto the splicing bolts 11, thereby locking the two angle steel keels 10 and completing the splicing and locking between the two roof panels 1.
[0045] Preferably, a sealing gasket is provided between the mating surfaces of the angle steel keel to increase the sealing performance of the roof panel 1 joint.
[0046] In a further embodiment of this solution, the surface steel plate of the roof panel 1 is provided with a vertical folded edge 106. The folded edge 106 is attached to the outer wall of the opposite side of the adjacent tenon 3. The clip 6 is inserted into the side wall of the waterproof cover plate 5, and the buckle 8 is installed on the folded edge 106.
[0047] Principle details of this embodiment:
[0048] The outer steel plate 101 of the roof panel 1 has a vertical folded edge 106 near the eaves of the roof panel 1. The folded edge 106 is attached to the outer wall of the opposite side of the adjacent tenon 3, the retaining pin 6 is inserted into the side wall of the waterproof cover plate 5, and the fastening edge 8 is installed on the folded edge 106. This provides an installation base for the splicing and locking system at the roof panel 1.
[0049] In Example 4, a further embodiment of this solution, the bottom end of the horizontal portion of the buckle 8 is provided with a groove 9 that mates with the U-shaped buckle 7. The cantilevered connection portion of the U-shaped buckle 7 is fastened in the groove 9, which restricts the U-shaped buckle 7, increases the installation stability of the U-shaped buckle 7, and prevents it from falling off.
[0050] In Example 5, a further embodiment of this solution, the waterproof cover 5 is made of a 2mm thick steel plate. This size requirement provides sufficient strength to prevent it from being bent by stress after being fastened to the two mortises 4, while minimizing weight for easy handling.
[0051] In a further embodiment of this solution, as described in Example 6, the tenon 3 is fastened to the roof panel 1 using bolts or other fasteners, or is fixed by welding. This achieves a fixed connection between the tenon 3 and the roof panel 1.
