Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane exterior wall panels, in particular to a polyurethane exterior wall panel with corrosion resistance. Background Art

[0002] Polyurethane exterior wall panels are a kind of building exterior wall decorative panels that use polyurethane materials as the main component. Polyurethane is a high-corrosion-resistant polymer material made by the reaction of polyols and isocyanates. It can be made into various forms such as foam plastics, elastomers, fibers, rubber, etc. Due to its unique properties, polyurethane exterior wall panels have been widely used in the field of construction. The reason why polyurethane exterior wall panels have excellent corrosion resistance is mainly due to the large number of urethane bonds contained in its molecular structure, which gives the material excellent chemical stability and aging resistance. It can resist the erosion of a variety of chemicals, including organic acids, alkalis, salts and common solvents, so it can maintain good performance in acidic or alkaline environments. These characteristics make polyurethane exterior wall panels particularly suitable for construction projects with special requirements for corrosion resistance, such as chemical plants, seaside buildings, sewage treatment facilities and other heavily corrosive areas. In addition, polyurethane exterior wall panels also have: thermal insulation performance, waterproof performance, and impact resistance. In terms of application, polyurethane exterior wall panels can be used as exterior wall decorative panels of buildings or as structural materials. Its colorful colors, rich board types and good processing performance provide architects with a variety of design options. At the same time, due to its environmental protection and recyclability, polyurethane exterior wall panels are also in line with the development trend of contemporary green buildings.

[0003] When the polyurethane exterior wall panels are connected to the wall, multiple polyurethane exterior wall panels need to be spliced ​​and connected. If there are gaps at the joints of multiple polyurethane exterior wall panels, the following problems may occur: Reduced thermal insulation performance: One of the main functions of polyurethane exterior wall panels is thermal insulation. If there are gaps at the joints, heat leakage will occur, reducing the thermal insulation effect of the building and increasing energy consumption. Weakened structural strength: During the construction process, polyurethane exterior wall panels not only have to bear the role of thermal insulation, but also play a certain structural support role. Gaps may weaken the overall strength and stability of the wall. Water vapor penetration: If there are gaps at the joints, water vapor may penetrate into the interior of the wall, causing the internal structure to become damp, affecting the service life and structural safety of the building. When installing polyurethane exterior wall panels, it is necessary to measure the length of the wall and the size of a single polyurethane exterior wall panel, and then calculate how many polyurethane exterior wall panels are needed based on the size. However, if the gaps between multiple polyurethane exterior wall panels are uneven, the installation results will deviate from the calculation results and affect the appearance. Summary of the invention

[0004] The utility model aims to solve the problems existing in the background technology and proposes a polyurethane exterior wall panel with corrosion resistance which can prevent gaps from appearing at the joints of multiple polyurethane exterior wall panels and ensure that the gaps between the multiple polyurethane exterior wall panels are equal.

[0005] The technical solution of the utility model is: a polyurethane exterior wall panel with corrosion resistance, comprising a panel body, a connecting block fixedly mounted on one side of the panel body, a connecting groove arranged on the other side of the panel body, and also comprising:

[0006] A sealing strip, which is fixedly installed on one side of the connection groove and seals the gaps at the connection points of the multiple plate bodies;

[0007] The limiting mechanism is installed in the connecting groove. When the multiple plate bodies are connected, the limiting mechanism keeps the pressing degree of the multiple plate bodies on the multiple sealing strips equal.

[0008] Optionally, the limiting mechanism includes a plurality of sliding holes provided in the connecting groove, a limiting column slidably installed in the sliding hole, a spring fixedly installed on the limiting column, and a plurality of limiting holes provided on the connecting block, and the other end of the spring is fixedly connected to the bottom of the sliding hole.

[0009] Optionally, the limiting column is provided with a chamfer, and the connecting block is provided with a chamfer on a side that is biased towards the limiting column.

[0010] Optionally, a sealing strip is fixedly installed in the connecting groove, and the sealing strip fills the gap between the connecting block and the connecting groove.

[0011] Optionally, the sealing strip is provided with a protrusion that supplements the chamfer on the connecting block.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] The gaps between multiple panels are compensated by sealing strips and blocking strips to prevent leakage or intrusion of gas, liquid or solid substances, thereby improving thermal insulation performance, reducing energy consumption and preventing structural strength from weakening;

[0014] Furthermore, the sealing strip is compressed by the limiting mechanism, thereby ensuring that the sealing strip and the blocking strip can fill the gaps between the multiple board bodies and can ensure that the gaps between the multiple board bodies remain equal, thereby improving the aesthetics of the wall.

[0021] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Example

[0023] like Figure 1-2 As shown, the utility model proposes a polyurethane exterior wall panel with corrosion resistance, including a board body 1, a connecting block 101 fixedly installed on one side of the board body 1, a connecting groove 102 arranged on the other side of the board body 1, and also includes a sealing strip 3, the sealing strip 3 is fixedly installed on one side of the connecting groove 102, the sealing strip 3 blocks the gaps at the connection points of multiple board bodies 1, and the sealing strip 3 is a strip-shaped object used to close and seal gaps to prevent leakage or intrusion of gas, liquid or solid substances.

[0024] like Figure 4-5As shown, the limiting mechanism is installed in the connecting groove 102. When multiple plate bodies 1 are connected, the limiting mechanism keeps the pressing degree of multiple plate bodies 1 on multiple sealing strips 3 equal. The limiting mechanism includes multiple sliding holes 2 arranged in the connecting groove 102, limiting columns 202 slidably installed in the sliding holes 2, springs 201 fixedly installed on the limiting columns 202, and multiple limiting holes 203 arranged on the connecting block 101, and the other end of the spring 201 is fixedly connected to the bottom of the sliding hole 2. The limiting column 202 is provided with a chamfer, and the connecting block 101 is provided with a chamfer on one side biased toward the limiting column 202. When multiple board bodies 1 are connected, the connecting block 101 on one of the board bodies 1 is inserted into the connecting groove 102. When the chamfer on the connecting block 101 contacts the chamfer on the limiting column 202, the board body 1 will contact the sealing strip 3. Continue to drag the board body 1 to extend the connecting block 101 into the connecting groove 102, and the limiting column 202 can be pushed to slide into the limiting hole 203. At this time, the spring 201 and the sealing strip 3 are compressed. When the limiting column 202 and the limiting hole 203 are in a coaxial position, the limiting column 202 will be driven to slide into the limiting hole 203 under the action of the spring 201. When the limiting column 202 enters the limiting hole 203, the connecting block 101 will be limited, so that the board body 1 cannot move, thereby ensuring that the gap between the two board bodies 1 is at an equal distance, and the gap between the two board bodies 1 is blocked by the sealing strip 3 to prevent gas, liquid or solid substances from leaking or intruding, thereby improving the thermal insulation effect of the building.

[0025] like Figure 4-5 As shown, a sealing strip 4 is fixedly installed in the connection groove 102, and the sealing strip 3 fills the gap between the connection block 101 and the connection groove 102. The sealing strip 4 is provided with a protrusion to supplement the chamfer on the connection block 101. When the connection block 101 enters the connection groove 102, the connection block 101 will contact the sealing strip 4 and compress the sealing strip 4, so that the sealing strip 4 blocks the gap between the connection block 101 and the connection groove 102, further ensuring the sealing between the plate body 1, and the chamfer on the connection block 101 will contact the protrusion on the sealing strip 4, so that the sealing strip 4 can be evenly stressed.

[0026] Working principle: When connecting multiple plate bodies 1, insert the connecting block 101 on one of the plate bodies 1 into the connecting groove 102. When the chamfer on the connecting block 101 contacts the chamfer on the limiting column 202, the plate body 1 contacts the sealing strip 3. Continue to drag the plate body 1 to extend the connecting block 101 into the connecting groove 102, and then push the limiting column 202 to slide into the limiting hole 203. At this time, the spring 201 and the sealing strip 3 are compressed. When the limiting column 202 contacts the limiting hole 203, the sealing strip 3 is pressed. 3 is in the coaxial position, the spring 201 will drive the limiting column 202 to slide into the limiting hole 203. When the limiting column 202 enters the limiting hole 203, the connecting block 101 will be limited, so that the plate body 1 cannot move, thereby ensuring that the gap between the two plate bodies 1 is at an equal distance, and the gap between the two plate bodies 1 is blocked by the sealing strip 3 to prevent gas, liquid or solid substances from leaking or intruding, thereby improving the thermal insulation effect of the building.
