Description

Technical Field

[0001] This invention relates to the field of color steel roofing technology, specifically a leak-proof color steel roofing connection structure and its installation method. Background Technology

[0002] The substrate of color-coated steel sheets can be cold-rolled, hot-dip galvanized, or electro-galvanized. Coating types include polyester, silicone-modified polyester, polyvinylidene fluoride (PVDF), and plastisol. Surface finishes include coated, embossed, and printed sheets. Color-coated steel sheets are widely used in construction, home appliances, and transportation industries. In the construction industry, they are mainly used for roofs, walls, and doors of steel structure factories, airports, warehouses, and cold storage facilities, as well as other industrial and commercial buildings.

[0003] Currently, when using color steel plate roofing, a cover plate is usually laid at the ridge to fold the joint between two roof sections and prevent leaks. However, due to the ridges on the color steel plates, the bottom of the cover plate cannot effectively fit the plate. Therefore, during storms, rainwater near the ridge on the color steel plate can easily flow upwards under strong winds, causing leaks at the ridge. Secondly, when adjacent color steel plates are spliced, the ridges at the ends of the two plates overlap, and self-tapping screws are used to fix them to the roof frame. While this method can guide rainwater, if the gap between the two overlapping plates is small, rainwater can easily seep into the joint through capillary action, leading to roof leaks. Therefore, this paper proposes a leak-proof color steel plate roofing connection structure and its installation method. Summary of the Invention

[0004] The present invention aims to solve the above problems, thereby providing a leak-proof color steel plate roof connection structure and its installation method.

[0005] The technical solution adopted by the present invention to solve the aforementioned problem is as follows:

[0006] A leak-proof color steel plate roof connection structure includes a roof frame and two sets of color steel plate roofs laid on the roof frame. Each set of color steel plate roofs is composed of several color steel plates spliced ​​together. A pressure strip is provided directly above the connection end of every two adjacent color steel plates, and a sealing strip is fixedly connected to the bottom of the pressure strip and the corresponding position of the two color steel plates. The pressure strip is fixedly connected to the roof frame. A ridge plate is provided above the adjacent ends of the two sets of color steel plate roofs. A rubber pressure strip is fixedly connected to the bottom of the ridge plate and the corresponding position of each set of color steel plate roofs. The bottom of the rubber pressure strip is in contact with the top surface of the color steel plate and the pressure strip. A water-stop strip is embedded in the bottom of the rubber pressure strip. The ridge plate is fixedly connected to the roof frame.

[0007] By using pressure strips and sealing strips, the joints of adjacent color steel plates can be pressed and sealed, effectively preventing water seepage at the joints. By using ridge plates, rubber pressure strips, and waterstop strips, the joints of two color steel plate roofs can be sealed, thus preventing ridge leakage. The effect is good.

[0008] Furthermore, the color steel plate is integrally formed with several ridges, and both ends of the color steel plate are ridges. The pressure strip is located directly above two adjacent ridges, and the bottom of the sealing strip is in contact with the top surface of the corresponding ridge. By fixing the color steel plate at adjacent ridges, when it rains, the rainwater falling on the ridges will slide down along the side wall of the ridges, thereby further improving the leak-proof effect.

[0009] Furthermore, the bottom of the rubber strip is provided with a groove that matches the ridge and the strip; the groove ensures a tight fit between the rubber strip and the ridge and the strip.

[0010] Furthermore, the roof frame includes several triangular trusses and purlins. The purlins are located under the corrugated steel roof and are fixedly connected to the triangular trusses. The corrugated steel sheet is fixedly connected to the purlins below it at its ridge by self-tapping screws.

[0011] Furthermore, a square tube is fixedly connected to the top of the purlin and the corresponding part of the pressure strip, and a plurality of first screws are fixedly connected to the bottom of the pressure strip. The bottom end of the first screw passes through the square tube and is connected to a first nut. Through the cooperation of the square tube, the first screw and the first nut, the pressure strip can be effectively fixed on the roof frame and the two sealing strips can be pressed tightly on the corresponding ridge.

[0012] Furthermore, several of the triangular trusses are fixedly connected to the top of a common mounting strip, and a second screw is fixedly connected to the center of the bottom surface of the ridge plate. The bottom end of the second screw passes through the mounting strip and is fitted with a U-shaped plate. Two rubber blocks are fixedly connected to the top of each U-shaped plate. The top surface of the rubber blocks fits against the bottom of the corresponding color steel plate. A second nut is threaded onto the outer wall of the second screw below the U-shaped plate. By tightening the second nut at the bottom of the second screw, the ridge plate can be pulled down to clamp the color steel plate using the rubber strip and rubber blocks. The operation is simple and convenient.

[0013] An installation method for a leak-proof color steel plate roof connection structure, comprising the following steps:

[0014] Step 1: After completing the fixed installation of the roof frame, fix the square tubes on the roof frame at the required intervals;

[0015] Step 2: Lay two corrugated steel roof panels on the roof frame and fix them to the purlins at the ridge of each corrugated steel panel using self-tapping screws. Then apply sealant to the self-tapping screws.

[0016] Step 3: Install pressure strips at the joints of each color steel plate and apply glue to the corresponding ridge surface to make the sealing strip adhere to the ridge;

[0017] Step 4: Lay the ridge panels at the adjacent ends of the two corrugated steel roofs, and make the ridge and the strip fit into the corresponding grooves;

[0018] Step 5: Install the first nut on the first screw below the color steel roof, and then install the Z-shaped plate and the second nut on the second screw below the color steel roof to complete the installation of the color steel roof.

[0019] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art:

[0020] This invention, through the setting of pressure strips and sealing strips, can press and seal the connection ends of adjacent color steel plates, thereby effectively preventing water seepage at the joints of adjacent color steel plates. Through the setting of ridge plate, rubber pressure strips and waterstop strips, the connection ends of two color steel plate roofs can be sealed, thereby preventing ridge leakage. It has good performance. Attached Figure Description

[0027] See Figures 1-4 A leak-proof color steel plate roof connection structure includes a roof frame and two sets of color steel plate roofs laid on the roof frame. Each set of color steel plate roofs is composed of several color steel plates 3 spliced ​​together. A pressure strip 6 is provided directly above the connection end of every two adjacent color steel plates 3, and a sealing strip 7 is fixedly connected to the bottom of the pressure strip 6 and the corresponding position of the two color steel plates 3. The pressure strip 6 is fixedly connected to the roof frame. A ridge plate 10 is provided above the adjacent ends of the two sets of color steel plate roofs. A rubber pressure strip 16 is fixedly connected to the bottom of the ridge plate 10 and the corresponding position of each set of color steel plate roofs. The bottom of the rubber pressure strip 16 is in contact with the top surface of the color steel plate 3 and the pressure strip 6. A water-stop strip 17 is embedded in the bottom of the rubber pressure strip 16. The ridge plate 10 is fixedly connected to the roof frame.

[0028] By adopting the above-mentioned scheme, the present invention utilizes the setting of pressure strip 6 and sealing strip 7 to press and seal the connection end of adjacent color steel plate 3, thereby effectively preventing water seepage at the joint of adjacent color steel plate 3. By setting the ridge plate 10, rubber pressure strip 16 and waterstop strip 17, the connection end of two color steel plate roofs can be sealed, thereby preventing the ridge from leaking. The effect is good.

[0029] See Figure 3 , Figure 4 The color steel plate 3 has several ridges 4 integrally formed on it, and both ends of the color steel plate 3 are ridges 4. The pressure strip 6 is located directly above two adjacent ridges 4, and the bottom of the sealing strip 7 is in contact with the top surface of the corresponding ridge 4.

[0030] By fixing the color steel plate 3 at the adjacent ridges 4, when it rains, the rainwater falling on the ridges 4 will slide down along the side wall of the ridges 4, thereby further improving the leak-proof effect.

[0031] See Figure 3 The bottom of the rubber strip 16 is provided with a groove that matches the ridge 4 and the strip 6. The groove ensures a tight fit between the rubber strip 16, the ridge 4, and the strip 6.

[0032] See Figure 1 The roof frame includes several triangular trusses 1 and purlins 2. The purlins 2 are located under the color steel roof and are fixedly connected to the triangular trusses 1. Furthermore, the color steel plate 3 is fixedly connected to the purlins 2 below it at its ridge 4 by self-tapping screws.

[0033] See Figure 3 , Figure 4A square tube 5 is fixedly connected to the top of the purlin 2 at the corresponding position of the pressure strip 6. A plurality of first screws 8 are fixedly connected to the bottom of the pressure strip 6. The bottom end of the first screw 8 passes through the square tube 5 and is connected to a first nut 9.

[0034] The square tube 5, the first screw 8 and the first nut 9 work together to effectively fix the pressure strip 6 on the roof frame and press the two sealing strips 7 onto the corresponding ridges 4.

[0035] See Figure 1 , Figure 2 A mounting strip 11 is fixedly connected to the top of several of the triangular trusses 1. A second screw 12 is fixedly connected to the middle of the bottom surface of the ridge plate 10. The bottom end of the second screw 12 passes through the mounting strip 11 and is fitted with a Z-shaped plate 13. Two rubber blocks 15 are fixedly connected to the top of each Z-shaped plate 13. The top surface of the rubber blocks 15 is in contact with the bottom of the corresponding color steel plate 3. A second nut 14 is threadedly connected to the outer wall of the second screw 12 below the Z-shaped plate 13.

[0036] By tightening the second nut 14 at the bottom of the second screw 12, the ridge panel 10 can be pulled down to clamp the color steel plate 3 using the rubber strip 16 and the rubber support block 15. The operation is simple and convenient.

[0037] The installation method of the above-mentioned leak-proof color steel plate roof connection structure includes the following steps:

[0038] Step 1: After completing the fixed installation of the roof frame, fix the square tubes 5 on the roof frame at the required intervals;

[0039] Step 2: Lay two color steel plate roofs on the roof frame, and fix each color steel plate 3 to the purlin 2 at the ridge 4 using self-tapping screws, and then apply sealant to the self-tapping screws.

[0040] Step 3: By placing pressure strips 6 at the joint ends of each color steel plate 3 and applying glue to the corresponding ridge 4, the sealing strip 7 is made to adhere to the ridge 4.

[0041] Step 4: Lay the ridge plate 10 at the adjacent ends of the two corrugated steel roofs, and make the ridge 4 and the pressure strip 6 fit into the corresponding grooves;

[0042] Step 5: Install the first nut 9 on the first screw 8 below the color steel roof, and then install the Z-shaped plate 13 and the second nut 14 on the second screw 12 below the color steel roof, thus completing the installation of the color steel roof.

[0043] This invention, through the setting of pressure strips and sealing strips, can press and seal the connection ends of adjacent color steel plates, thereby effectively preventing water seepage at the joints of adjacent color steel plates. Through the setting of ridge plate, rubber pressure strips and waterstop strips, the connection ends of two color steel plate roofs can be sealed, thereby preventing ridge leakage. It has good performance.
