Description

Technical Field

[0001] This utility model belongs to the field of profiled steel sheet roofing installation technology, specifically a profiled steel sheet roofing structure. Background Technology

[0002] With the continuous expansion of industrial building construction, profiled steel sheets, as a green building material, have many advantages such as excellent thermal insulation performance and convenient installation. Therefore, profiled steel sheets are increasingly widely used in the roofing systems of industrial plants.

[0003] However, due to the limitations of current profiled steel sheet production technology, in engineering practice, the common method used is to use self-tapping screws to penetrate the profiled steel sheet and directly connect it to the roof purlins. However, this method has significant drawbacks. When the profiled steel sheet expands and contracts due to changes in ambient temperature along its length, the resulting internal stress will continue to accumulate. Over time, the holes at the self-tapping screws will continue to enlarge due to repeated stress, causing the waterproof seal to fail and rainwater to easily seep in. More seriously, under such stress for a long time, the self-tapping screws will be sheared due to fatigue damage, which will lead to the destruction of the structural integrity of the entire roof system and ultimately the loss of its load-bearing and protective functions.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a profiled steel sheet roofing structure.

[0005] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a profiled steel sheet roofing structure to address the issue in the prior art where the holes at the self-tapping screws continuously enlarge due to repeated stress, causing the waterproof seal to fail and rainwater to easily seep in.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that the drawings are schematic and not illustrated to scale. For clarity and convenience, the relative sizes and proportions of the parts shown in the drawings have been exaggerated or reduced in size. Any size is only illustrative and not limiting.

[0026] Example 1:

[0027] Please see Figure 1 - Figure 5 As shown, a profiled steel sheet roofing structure includes a first roof profiled steel sheet 1 and a second roof profiled steel sheet 2.

[0028] The first roof profiled steel sheet 1 has a first mounting groove 101 at its lower end. The inner wall of the first mounting groove 101 is provided with a locking component 11. The lower end of the side wall of the second roof profiled steel sheet 2 is fixedly connected to a second connecting plate 21. The side wall of one end of the second connecting plate 21 has a connecting groove 211. The inner wall of the connecting groove 211 has a through groove 212. The upper end of the connecting groove 211 is provided with a bending plate 22. The lower ends of the first roof profiled steel sheet 1 and the second roof profiled steel sheet 2 are provided with roof purlins 3.

[0029] The locking assembly 11 includes a locking plate 111 fixedly connected to the side wall of the first mounting groove 101. The side wall of the locking plate 111 has a first placement groove 112. A spring 113 is fixedly connected to the inner wall of the first placement groove 112. A locking block 114 is fixedly connected to one end of the spring 113.

[0030] As can be seen from the above, the second connecting plate 21 on the side wall of the second roof profiled steel sheet 2 is first fixed to the roof purlin 3 by screws and bending plate 22. Then, the first roof profiled steel sheet 1 is pushed towards the second roof profiled steel sheet 2, so that the locking plate 111 of the locking component 11 in the first mounting groove 101 at the lower end of the first roof profiled steel sheet 1 slides into the connecting groove 211 of the second connecting plate 21. During the sliding process, the locking block 114 is squeezed by the inner wall of the connecting groove 211, compresses the spring 113 and slides into the first placement groove 112. When the locking block 114 slides to the position of the through groove 212, the spring 113 returns to its original position and pushes the locking block 114 into the through groove 212, thereby realizing the initial connection of the first roof profiled steel sheet 1 and the second roof profiled steel sheet 2. It is not necessary to use screws to penetrate the profiled steel sheet for fixing, which further enhances the sealing of the connection, effectively prevents rainwater from seeping in, and avoids the problem of waterproof seal failure caused by the enlargement of the hole at the self-tapping screw.

[0031] Example 2:

[0032] This embodiment is basically the same as the previous embodiment, except that a first connecting plate 12 is fixedly connected to the inner wall of the middle part of the first mounting groove 101, a first abutting groove 121 is opened at the lower end of the first connecting plate 12, a first abutting block 122 is fixedly connected to one end of the first connecting plate 12, a fourth mounting groove 213 is opened on the side wall of the middle part of the upper end of the second connecting plate 21, a second abutting groove 214 is opened on the inner side wall of the fourth mounting groove 213, and a second abutting block 215 is fixedly connected to the side wall of the second connecting plate 21.

[0033] A retaining plate 13 is fixedly connected to the side wall of the first roof profiled steel sheet 1. A clamping plate 14 is fixedly connected to the upper side wall of the retaining plate 13. A connecting block 23 is fixedly connected to the upper surface of one end of the second roof profiled steel sheet 2. A slot 24 is provided on the side wall of the connecting block 23. By using the clamping plate 14 and the slot 24 to engage, the limiting connection between the first roof profiled steel sheet 1 and the second roof profiled steel sheet 2 is realized. At the same time, in conjunction with the inclined roof, this engaging connection method can also achieve the effect of waterproofing.

[0034] The top wall of the first mounting groove 101 is provided with a second mounting groove 102, and the side wall of one end of the abutment plate 13 is provided with a second placement groove 131 for placing the bent plate 22 to reduce the warping of the installation edge.

[0035] The side wall of the card plate 14 is provided with a third mounting groove 141, and the inner wall of the third mounting groove 141 is provided with a rubber strip 15 to increase the sealing performance.

[0036] The end of the locking block 114 near the spring 113 is slidably connected to the inner wall of the first placement groove 112, and the end of the locking block 114 away from the spring 113 is provided with an inclined surface.

[0037] As can be seen from the above, the first connecting plate 12 in the middle of the first mounting groove 101 moves with the first roof profiled steel sheet 1, and the first abutting block 122 will be inserted into the second abutting groove 214 in the fourth mounting groove 213 on the second connecting plate 21; at the same time, the second abutting block 215 will be inserted into the first abutting groove 121 at the lower end of the first connecting plate 12, limiting the middle of the two profiled steel sheets and enhancing the connection stability. The clamping plate 14 on the abutting plate 13 on the side wall of the first roof profiled steel sheet 1 will engage with the clamping groove 24 of the connecting block 23 on the upper surface of one end of the second roof profiled steel sheet 2 to achieve the top limiting connection. The rubber strip 15 in the third mounting groove 141 on the side wall of the clamping plate 14 will fill the gap when engaged, further enhancing the sealing of the connection and effectively preventing rainwater from seeping in.
