Description

Technical Field

[0001] This utility model relates to the field of engineering waterproofing, and in particular to a water-stopping copper sheet riveting structure. Background Technology

[0002] Many buildings currently have expansion joints. To prevent water leakage at these joints, copper sheets are often used for waterproofing. However, since a single copper sheet may not be long enough, splicing is sometimes necessary. Welding is a common splicing method, but it involves open flames, which pose safety hazards. To ensure safety, more and more buildings are using riveting to splice copper sheets. Patent CN208067231U discloses a device for riveting copper sheets. However, the two copper sheets riveted by this device may develop gaps due to thermal expansion and contraction, resulting in relatively poor reliability. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a water-stop copper sheet riveting structure. By placing a soft rubber pad between the first and second copper sheets, the gap between the first and second copper sheets is sealed using the soft rubber pad, ensuring the airtightness between the first and second copper sheets. At the same time, no heating or open flame is required during riveting, eliminating the risk of fire.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A water-stop copper sheet riveting structure includes a first copper sheet, a second copper sheet, cold rivets, and a soft rubber pad. The soft rubber pad is disposed between the first copper sheet and the second copper sheet. The first copper sheet, the soft rubber pad, and the second copper sheet are riveted together by the cold rivets. The cold rivets are perpendicular to the first copper sheet, the second copper sheet, and the soft rubber pad. There are multiple cold rivets, which do not contact each other and are in a parallel state.

[0006] In this riveting structure, a soft rubber pad is placed at the riveting point between the first copper sheet and the second copper sheet. Due to the presence of the soft rubber pad, there is no gap between the first copper sheet and the second copper sheet. Therefore, when the cold rivet rivets the first copper sheet, the soft rubber pad, and the second copper sheet together, a large copper plate with almost no gaps can be formed.

[0007] Meanwhile, since this type of riveting structure uses cold rivets, which do not require heating or open flames, there is no fire hazard.

[0008] In this type of riveting structure, since the cold rivet is perpendicular to the first copper sheet, the second copper sheet, and the soft rubber pad, the cold rivet can stably anchor the first copper sheet, the second copper sheet, and the soft rubber pad together.

[0009] In this type of riveting structure, the lack of contact between the cold rivets ensures a smooth and quick riveting operation.

[0010] In summary, this structure, by placing a soft rubber gasket between the first and second copper sheets, seals the gap between them, ensuring the airtightness of the first and second copper sheets. Furthermore, no heating or open flame is required during riveting, eliminating any fire hazard.

[0011] Optionally, the first copper sheet has a serrated surface, the second copper sheet has a serrated surface, the serrated surfaces of the first copper sheet and the second copper sheet are in close contact with the soft rubber pad, and the cold rivet does not contact the serrated surface.

[0012] A serrated surface is provided on the first and second copper sheets. Both the first and second copper sheets are tightly adhered to the soft rubber pad through the serrated surface. This ensures the stability of the adhesion between the first and second copper sheets and the soft rubber pad, and ensures good sealing of the entire structure. The presence of the serrated surface can increase the friction between the first and second copper sheets, preventing the first and second copper sheets from moving relative to the soft rubber pad.

[0013] At the same time, since the cold rivet does not come into contact with the sawtooth surface, this is to avoid the cold rivet damaging the sawtooth surface during the riveting operation.

[0014] Optionally, the serrated surface of the first copper sheet is misaligned with the serrated surface of the second copper sheet.

[0015] The serrated surfaces of the first copper sheet and the second copper sheet are misaligned, which is equivalent to the serrated surfaces on both sides of the soft rubber pad being misaligned. This misalignment of the serrated surfaces can improve the interlocking strength between the first and second copper sheets and the soft rubber pad, and also facilitates the twisting and deformation of the soft rubber pad in the middle, thus ensuring that there are no gaps.

[0016] Optionally, the cross-section of the saw teeth on the saw tooth surface is an isosceles triangle shape.

[0017] The cross-section of the saw teeth is an isosceles triangle shape, which ensures that the saw teeth on the saw teeth surface can be embedded in the soft rubber pad.

[0018] Optionally, it may also include adhesive columns, which are filled within the cold rivet.

[0019] Because cold rivets have internal cavities after riveting, glue is filled into these cavities to ensure a good seal. Once the glue solidifies, it forms a glue column, which ensures that there are no gaps in the cold rivet after riveting.

[0020] Optionally, the distance between two adjacent cold rivets is equal.

[0021] Optionally, the first copper sheet and the second copper sheet have the same thickness, and the thickness of the soft rubber pad is less than the thickness of the first copper sheet.

[0022] Specifically, the length of the cold rivet is greater than the sum of the thickness of the first copper sheet, the thickness of the second copper sheet, and the thickness of the soft rubber pad.

[0023] Optionally, the cold rivet is a cold rivet made of copper, the first copper sheet is a first copper sheet made of copper, and the second copper sheet is a second copper sheet made of copper.

[0024] Copper is used to prevent corrosion, while the soft rubber pads are made of materials including, but not limited to, EDPM (ethylene propylene diene monomer) rubber. The cold-applied rivets are distributed in a multi-row dotted line arrangement.

[0025] The beneficial effects of this utility model are: by setting a soft rubber pad between the first copper sheet and the second copper sheet, the gap between the first copper sheet and the second copper sheet can be sealed by the soft rubber pad, which can ensure the sealing between the first copper sheet and the second copper sheet. At the same time, no heating or open flame is required during riveting, so there is no fire hazard. Attached Figure Description

It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0033] As attached Figure 1 and appendix Figure 2 As shown, a water-stop copper sheet riveting structure includes a first copper sheet 1, a second copper sheet 2, cold rivets 6, and a soft rubber pad 3. The soft rubber pad 3 is disposed between the first copper sheet 1 and the second copper sheet 2. The first copper sheet 1, the soft rubber pad 3, and the second copper sheet 2 are riveted together by the cold rivets 6. The cold rivets 6 are perpendicular to the first copper sheet 1, the second copper sheet 2, and the soft rubber pad 3. There are multiple cold rivets 6, and the cold rivets 6 do not contact each other. The cold rivets 6 are in a parallel state and are perpendicular to the first copper sheet 1, the second copper sheet 2, and the soft rubber pad 3.

[0034] In this riveting structure, a soft rubber pad 3 is placed at the riveting point between the first copper sheet 1 and the second copper sheet 2. Due to the presence of the soft rubber pad 3, there is no gap between the first copper sheet 1 and the second copper sheet 2. Therefore, when the cold rivet 6 rivets the first copper sheet 1, the soft rubber pad 3 and the second copper sheet 2 together, a large copper plate with almost no gaps can be formed.

[0035] Meanwhile, in this type of riveting structure, since cold rivets 6 are used, there is no need to heat or open flame, and there is no fire hazard.

[0036] In this riveting structure, since the cold rivet 6 is perpendicular to the first copper sheet 1, the second copper sheet 2 and the soft rubber pad 3, the cold rivet 6 can stably anchor the first copper sheet 1, the second copper sheet 2 and the soft rubber pad 3 together.

[0037] In this type of riveting structure, the fact that the individual cold rivets 6 do not contact each other ensures that the riveting operation is smooth and quick.

[0038] In summary, this structure ensures the airtightness between the first copper sheet 1 and the second copper sheet 2 by placing a soft rubber pad 3 between the first copper sheet 1 and the second copper sheet 2 and sealing the gap between them. At the same time, no heating or open flame is required during riveting, so there is no fire hazard.

[0039] As attached Figure 1 and appendix Figure 2 As shown, a serrated surface 4 is provided on the first copper sheet 1 and the second copper sheet 2. The serrated surfaces 4 of the first copper sheet 1 and the second copper sheet 2 are closely attached to the soft rubber pad 3, and the cold rivet 6 does not contact the serrated surface 4.

[0040] A serrated surface 4 is provided on the first copper sheet 1 and the second copper sheet 2. Both the first copper sheet 1 and the second copper sheet 2 are tightly attached to the soft rubber pad 3 through the serrated surface 4. This ensures the stability of the adhesion between the first copper sheet 1 and the second copper sheet 2 and the soft rubber pad 3, and ensures good sealing of the entire structure. The presence of the serrated surface 4 can increase the friction between the first copper sheet 1 and the second copper sheet 2, preventing the first copper sheet 1 and the second copper sheet 2 from moving relative to the soft rubber pad 3.

[0041] Meanwhile, since the cold rivet 6 does not contact the serrated surface 4, this is to avoid the cold rivet 6 damaging the serrated surface 4 during the riveting operation.

[0042] As attached Figure 1 and appendix Figure 2 As shown, the serrated surface 4 of the first copper sheet 1 is misaligned with the serrated surface 4 of the second copper sheet 2.

[0043] The serrated surface 4 of the first copper sheet 1 and the serrated surface 4 of the second copper sheet 2 are misaligned. This is equivalent to the serrated surfaces 4 on both sides of the soft rubber pad 3 being misaligned. This misalignment of the serrated surfaces 4 can improve the interlocking strength between the first copper sheet 1 and the second copper sheet 2 and the soft rubber pad 3, and also facilitates the twisting deformation of the soft rubber pad 3 in the middle, thus ensuring that there are no gaps.

[0044] As attached Figure 1 and appendix Figure 2 As shown, the cross-section of the serrations on the serrated surface 4 is an isosceles triangle.

[0045] The cross-section of the serrations is an isosceles triangle shape, which ensures that the serrations on the serration surface 4 can be embedded in the soft rubber pad 3.

[0046] As attached Figure 1 and appendix Figure 2 As shown, it also includes a glue column 5, which is filled inside the cold rivet 6.

[0047] Because the cold rivet 6 has an internal cavity after riveting, glue is filled into the cavity inside the cold rivet 6 to ensure a good seal. The glue fills the cavity and forms a glue column 5 after it solidifies. The presence of the glue column 5 ensures that the cold rivet 6 has no gaps after riveting.

[0048] As attached Figure 1 and appendix Figure 2 As shown, the distance between two adjacent cold rivets 6 is equal.

[0049] As attached Figure 1 and appendix Figure 2 As shown, the first copper sheet 1 and the second copper sheet 2 have the same thickness, and the thickness of the soft rubber pad 3 is less than the thickness of the first copper sheet 1.

[0050] Specifically, the length of the cold rivet 6 is greater than the sum of the thicknesses of the first copper sheet 1, the second copper sheet 2, and the soft rubber pad 3.

[0051] As attached Figure 1 and appendix Figure 2 As shown, the cold rivet 6 is a cold rivet 6 made of copper, the first copper sheet 1 is a first copper sheet 1 made of copper, and the second copper sheet 2 is a second copper sheet 2 made of copper.

[0052] Copper is used to prevent corrosion, while the soft rubber pad 3 is made of, but is not limited to, EDPM (ethylene propylene diene monomer) rubber. The cold rivets 6 are distributed in a multi-row dotted line arrangement.

[0053] The above-described embodiments only illustrate some aspects of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
