Description

Technical Field

[0001] The utility model relates to the technical field of sealing structures, in particular to a sealing structure for curtain wall leakage prevention. Background Art

[0002] At present, the space between the top plates of the stone curtain wall is only filled with silicone sealant. Since the outer front of the top plate faces the rain, there are problems of insufficient sealing and aging of the silicone sealant, and it is impossible to completely prevent rainwater leakage.

[0003] The publication number is CN205000515U. On January 27, 2016, a connection structure of the top pressure plates in the stone curtain wall was disclosed. The stone plates are connected to form a multi-level waterproof structure, which can effectively prevent rainwater leakage and increase the service life of the sealant or foam rod. However, since the gasket is made of hard material, gaps will still appear between the top pressure plates, allowing rainwater to penetrate and accelerate the aging of the sealant or foam rod. Utility Model Content

[0004] In view of the above problems, the utility model provides a sealing structure for curtain wall leakage prevention, in which rubber strips are fixed between curtain wall panels and clamping plates to reduce the gap between the curtain wall panels and the clamping plates, and at the same time a drainage cavity is formed between the rubber strips.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A sealing structure for curtain wall leakage prevention, which is arranged between two adjacent curtain wall panels and comprises a keel, weather-resistant glue and a plywood. The weather-resistant glue is fixed between the two curtain wall panels, and plywood is fixed at both ends of the weather-resistant glue. Both sides of the plywood extend to the surface of the curtain wall panels and abut against the curtain wall panels; the bottom of the plywood under the curtain wall panels is fixed to the keel; a rubber strip is arranged between the plywood and the curtain wall panels, and the rubber strip is tightly abutted against the curtain wall panels and the plywood, and a drainage cavity is formed between the two rubber strips.

[0007] Furthermore, the bottom of the bolt sequentially penetrates the plywood at the top of the curtain wall panel, the weather-resistant glue, the plywood at the bottom of the curtain wall panel and the keel, and is then threadedly connected to the nut, and the top of the nut abuts against the keel.

[0008] Furthermore, a gasket is abutted between the nut and the keel.

[0009] Furthermore, a rubber gasket is abutted between the gasket and the keel.

[0010] Furthermore, a foam rod is fixed in the middle of the weather-resistant glue.

[0011] Furthermore, the width of the weather-resistant glue is 1.5-2 cm.

[0012] Furthermore, the material of the clamping plate is aluminum.

[0013] Furthermore, the rubber strip is a water-swellable waterproof rubber strip.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model fixes rubber strips between the curtain wall panels and the clamping plates to reduce the gap between the curtain wall panels and the clamping plates, and at the same time forms a drainage cavity between the rubber strips.

[0016] 2. The rainwater infiltrated by the utility model can be guided to drain through the drainage cavity, thereby effectively preventing the foam rod from oxidation and aging, and effectively improving the service life.

[0017] 3. The utility model compresses the rubber gasket on one side of the gasket to deform by rotating the nut in cooperation with the bolt, and utilizes the elastic force of the rubber gasket to apply a force in one direction to the gasket, which can effectively prevent the nut from loosening, thereby ensuring the clamping force of the splint.

[0018] 4. The utility model arranges a cable arrangement plate and a cable arrangement groove under the switch body, so that the network cables connected to the switch can be arranged in a standardized and neat manner, which is convenient for maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] like Figure 1-Figure 5As shown, the sealing structure for curtain wall leakage prevention in this embodiment is arranged between two adjacent curtain wall panels 1, and includes a keel 2, a weather-resistant glue 3 and a plywood 4. The weather-resistant glue 3 is fixed between the two curtain wall panels 1, and plywood 4 is fixed at both ends of the weather-resistant glue 3. Both sides of the plywood 4 extend to the surface of the curtain wall panel 1 and abut against the curtain wall panel 1; the bottom of the plywood 4 under the curtain wall panel 1 is fixed to the keel 2; a rubber strip 5 is arranged between the plywood 4 and the curtain wall panel 1, and the rubber strip 5 is tightly abutted against the curtain wall panel 1 and the plywood 4, and a drainage cavity 6 is formed between the two rubber strips 5.

[0027] The rubber strip 5 is fixed between the curtain wall panel 1 and the plywood 4 to reduce the gap between the curtain wall panel 1 and the plywood 4. At the same time, a drainage cavity 6 is formed between the rubber strips 5. The infiltrated rainwater can be drained through the drainage cavity 6, thereby effectively preventing the foam rod 11 from oxidation and aging, and effectively improving the service life. The joints where the plywood 4 are connected are coated with waterproof sealant.

[0028] Furthermore, the bottom of the bolt 7 sequentially passes through the clamping plate 4 at the top of the curtain wall panel 1 , the weather-resistant glue 3 , the clamping plate 4 at the bottom of the curtain wall panel 1 and the keel 2 , and is then threadedly connected with the nut 8 , and the top of the nut 8 abuts against the keel 2 .

[0029] The clamping plate 4 on the outer surface of the curtain wall panel 1 is provided with a countersunk hole at a position corresponding to the bolt 7. The countersunk hole allows the end of the bolt 7 to sink into the inner side of the countersunk hole to ensure the aesthetics of the assembly.

[0030] Furthermore, a gasket 9 is abutted between the nut 8 and the keel 2 .

[0031] Furthermore, a rubber gasket 10 is abutted between the gasket 9 and the keel 2 .

[0032] The nut 8 cooperates with the bolt 7 to rotate, and the rubber gasket 10 on one side of the gasket 9 is pressed to deform. The elastic force of the rubber gasket 10 is used to apply a force in one direction to the gasket 9 to effectively prevent the nut 8 from loosening, thereby ensuring the clamping force of the clamping plate 4.

[0033] Furthermore, a foam rod 11 is fixed in the middle of the weather-resistant adhesive 3 .

[0034] Fill the inner side of the joint of the curtain wall panel 1 with a foam rod 11, use the foam rod 11 to fill the gap in the joint, then apply weather-resistant glue 3 on the inner side of the joint to cover the foam rod 11 on the inner side of the joint to prevent the foam rod 11 from oxidizing. When the surface weather-resistant glue 3 is damaged, the foam rod 11 can prevent water from continuing to penetrate into the inner side of the curtain wall panel 1.

[0035] Furthermore, the width of the weather-resistant glue 3 is 1.5-2 cm.

[0036] Furthermore, the material of the clamping plate 4 is aluminum.

[0037] Furthermore, the rubber strip 5 is a water-swellable waterproof rubber strip.

[0038] The method of using the utility model is:

[0039] By filling the inner side of the joint of the curtain wall panel 1 with foam rods 11, and then applying weather-resistant glue 3 on the inner side of the joint to cover the foam rods 11 on the inner side of the joint to prevent the foam rods 11 from oxidizing, and placing two plywood panels 4 at the joint, and then using bolts 7 to penetrate the plywood 4, and installing the keel 2 at the end of the bolt 7, installing the nut 8 at the end of the bolt 7 and rotating it until the nut 8 cannot be screwed in, the water-swelling water-stop strip 5 is in contact with the curtain wall panel 1, which can play a good waterproof role, and a small amount of rainwater that penetrates can be guided to drain through the drainage cavity 6.

[0040] 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 the 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.
