Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of profiled steel sheet roofs, in particular to a waterproof structure for a colored profiled steel sheet roof with strong impact resistance. Background Technique
[0002] The formed steel sheet with a corrugated cross-section formed along the width direction of the plate by roll-pressing and cold-bending a coated or plated sheet is called profiled steel sheet. When the profiled steel sheet is used as the roof panel or wall panel of an industrial factory building, in the case of generally no heat preservation requirement, the steel consumption per square meter is about 5-11 kg. When there is a heat preservation requirement, mineral wool board, glass wool, foam plastic, etc. can be used as heat-insulating materials. The profiled steel sheet and concrete are combined to form a composite floor slab, which can save the wooden formwork and can be used as a load-bearing structure. At the same time, in order to strengthen the bonding force between the profiled steel sheet and the concrete, it is advisable to pre-weld stud bolts or press double-sided stiffening ribs on the steel sheet.
[0003] However, for the existing roof waterproof structure, due to the general buffering performance during impact resistance, the problem of the decline in waterproof performance after the protective structure is damaged by impact occurs; therefore, it does not meet the existing requirements, and for this reason, we propose a roof waterproof structure with strong impact resistance.
[0004] Therefore, we propose a waterproof structure for a colored profiled steel sheet roof with strong impact resistance. Content of the Utility Model

Specific embodiments
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Please refer to Figures 1 to 3, the present utility model provides a waterproof structure for a colored profiled steel sheet roof with strong impact resistance, including a profiled steel sheet roof 1. A fixing groove 2 is opened at the splicing position of two profiled steel sheet roofs 1. A buffer pad 9 is arranged outside the splicing position of two profiled steel sheet roofs 1. A fixing block 3 is arranged inside the fixing groove 2. Threaded holes 13 are opened at the upper and lower ends on one side of the fixing block 3. Sealing strips 15 are integrally arranged at the upper and lower ends of the buffer pad 9. A pressing plate 12 is in tight contact with the side of the sealing strip 15 away from the profiled steel sheet roof 1. A fixing bolt 14 that is threadedly and fixedly connected to the threaded hole 13 is arranged through the middle of the pressing plate 12. An elastic cavity 10 is opened inside the buffer pad 9. A buffer cavity 4 is opened inside the fixing block 3. A buffer airbag 5 communicated with the elastic cavity 10 is arranged inside the buffer cavity 4. By arranging the buffer pad 9 and the buffer airbag 5, when the buffer pad 9 is impacted, the elastic cavity 10 is stressed and shrinks, and the gas stored in the elastic cavity 10 is conveyed into the inside of the buffer airbag 5 through the through hole 11 and the connecting pipe 8. The buffer airbag 5 expands and absorbs the impact force under the action of the abutting spring 7, so that the elastic cavity 10 transmits the impact force for buffering, enabling the waterproof structure to resist stronger impact forces.
[0025] Clamping plates 6 are slidably arranged inside the buffer cavity 4 on the upper and lower sides of the buffer airbag 5. Abutting springs 7 are fixedly installed on the upper and lower sides inside the buffer cavity 4. The other ends of the abutting springs 7 are in tight contact with the clamping plates 6. By arranging the clamping plates 6 and the abutting springs 7, the abutting springs 7 push the two clamping plates 6 to squeeze the buffer airbag 5, so that the gas inside the buffer airbag 5 and the elastic cavity 10 maintains pressure, enabling the elastic cavity 10 to rebound by itself after being stressed, and enabling the waterproof structure to buffer multiple impacts repeatedly, increasing the practicability.
[0026] The thickness of the fixing block 3 is the same as the depth of the fixing groove 2. The upper and lower sides of the fixing block 3 are respectively in tight contact with the fixing grooves 2 of the two profiled steel sheet roofs 1.
[0027] One side of the buffer pad 9 located outside the profiled steel sheet roof 1 is arc-shaped. The other side of the buffer pad 9 is provided with a convex strip that abuts against two adjacent profiled steel sheet roofs 1.
[0028] The elastic cavity 10 and the buffer airbag 5 are correspondingly arranged. A through hole 11 communicated with the elastic cavity 10 is opened on one side of the buffer pad 9. A connecting pipe 8 that penetrates the fixing block 3 is integrally arranged on one side of the buffer airbag 5. The connecting pipe 8 is communicated with the through hole 11.
[0029] The connecting pipe 8 is inserted into the convex strip inside the buffer pad 9, and the connecting pipe 8 is in tight seal with the through hole 11 opened on the buffer pad 9.
[0030] The width of the pressing plate 12 is the same as that of the sealing strip 15 . The sealing strip 15 is provided with a small hole corresponding to the threaded hole 13 . The diameter of the small hole provided in the sealing strip 15 is smaller than the diameter of the threaded hole 13 .
[0031] Working principle:
[0032] When the buffer pad 9 is impacted, the elastic cavity 10 contracts under the force, and the gas stored in the elastic cavity 10 is transported into the interior of the buffer airbag 5 through the through hole 11 and the connecting pipe 8. The buffer airbag 5 expands and absorbs the impact force under the action of the clamping spring 7, so that the elastic cavity 10 transmits the impact force for buffering, so that the waterproof structure can withstand stronger impact force. By setting the clamping plate 6 and the clamping spring 7, the clamping spring 7 pushes the two clamping plates 6 to squeeze the buffer airbag 5, so that the gas inside the buffer airbag 5 and the elastic cavity 10 maintains pressure, so that the elastic cavity 10 can rebound by itself after being subjected to force, so that the waterproof structure can repeatedly buffer multiple impacts, thereby increasing practicality.
[0033] In the above embodiment, a blind hole can be set on the side of the fixing groove 2, and an abutment plate 41 is also installed inside the buffer cavity 4. The abutment plate 41 and the clamping plate 6 are respectively connected to the two ends of the clamping spring 7. A connecting rod 42 is set on the abutment plate 41 to penetrate the fixing block 3. The end of the connecting rod 42 is used to axially socket in the blind hole. In the initial state, the clamping spring 7 is in a natural state and is not subject to compression force. The buffer airbag 5 can pull the two clamping plates 6 closer to each other. The elastic cavity 10 is naturally bent and the air inside the buffer airbag 5 is sucked out. When the buffer pad 9 is hit, the elastic cavity 10 is forced to shrink and the gas stored in the elastic cavity 10 is transported into the interior of the buffer airbag 5 through the through hole 11 and the connecting pipe 8. The buffer airbag 5 expands, driving the clamping spring 7 to move outward, and only the connecting rod 42 moves outward and is socketed in the blind hole to prevent the fixing block 3 and the fixing groove 2 from separating when subjected to a large impact.
[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
