Description

Technical Field

[0001] The present invention belongs to the technical field of rubber and plastic boards, and particularly relates to a lightweight rubber and plastic insulation board with a connection system. Background Art

[0002] As a multi-functional material composed of a composite of rubber and plastic, rubber and plastic boards are widely used in heat insulation, vibration isolation, and noise control in the fields of architecture, machinery, chemical engineering, etc. due to their excellent heat insulation, waterproof and moisture-proof properties, compressive strength, and elasticity.

[0003] However, with the improvement of building energy efficiency standards and the increasingly strict fire safety requirements, the limitations of traditional rubber and plastic insulation boards have gradually emerged, mainly reflected in the following aspects: Poor installation stability: Traditional boards are mostly in the form of integral plate structures, lacking effective connection designs at the edges. When spliced together, they are prone to dislocation and loosening. Especially in environments with wind pressure or vibration, the joints are prone to cracking, resulting in the shedding of the insulation layer and affecting the durability of the project. Contradiction between weight and strength: To improve mechanical properties, some products achieve this by increasing the material density, but this sacrifices the lightweight advantage and increases transportation and construction costs. Therefore, it is necessary to design a lightweight rubber and plastic insulation board with a connection system to solve the above problems. Summary of the Invention

[0022] As can be seen from the above description, the present invention has the following beneficial effects: When in use, the rubber and plastic main board 1 is used to install the thermal insulation layer board 3 and the reinforcing board 4, so that a variety of boards can be used in combination, making the use functions of the rubber and plastic insulation board more diverse. Moreover, both the thermal insulation layer board 3 and the reinforcing board 4 are arranged in a honeycomb shape, which reduces the weight while ensuring heat insulation, and the honeycomb structure can enhance the supporting ability and reduce the phenomenon of deformation.

[0023] Embodiment 2: Please refer to Figures 1 to 12 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: The connecting main frame 21 includes a connecting main board 211, the connecting main board 211 is installed in the groove on the upper surface of the rubber and plastic board main shell 11, and a plug post 212 is fixedly connected to the lower side of one end of the connecting main board 211. The connecting plug post 212 is inserted into the inner side of the connecting seat 23, and a connecting card slot 213 is opened on one side of the lower end of the connecting plug post 212. Through the insertion and fixation of the connecting plug post 212, and in cooperation with the clamping of the connecting main board 211, the connection is carried out, which is convenient for splicing between the boards and ensures the horizontal consistency. An installation slot 231 is opened on the inner side of the connecting seat 23, the connecting plug post 212 is installed in the installation slot 231, and a reinforcement card slot 232 is opened on the inner side wall of the installation slot 231. One end of the reinforcement plug post 24 passes through the reinforcement card slot 232 and is inserted into the connecting card slot 213. The reinforcement plug post 24 includes a reinforcement main seat 241 installed in the reinforcement card slot 232. The reinforcement main seat 241 is fixed with a push spring 242 through a screw, one end of the push spring 242 is fixed with a push seat 243 through a screw, a reinforcement plug 244 is fixed on the side of the push seat 243, the push seat 243 and the reinforcement plug 244 are slidably installed at one end of the reinforcement main seat 241, and one end of the reinforcement plug 244 passes through the reinforcement card slot 232 and is clamped in the connecting card slot 213. When the connecting plug post 212 is inserted into the connecting card slot 213 during installation, the reinforcement plug 244 is pushed to compress the push spring 242, and after insertion, the push spring 242 pushes the reinforcement plug 244 to be clamped in the connecting card slot 213. One end of the reinforcement plug 244 is set in a hemispherical shape, which is convenient for pushing the reinforcement plug 244 to slide. One end of the reinforcement main seat 241 is fixedly installed on the inner wall of the rubber and plastic board bottom shell 12 through a bolt, making the reinforcement main seat 241 more stable during installation and use.

[0024] For the connecting mechanism 2 adopting the above technical solution, when in use, the rubber and plastic main boards 1 are spliced and assembled through the connecting main frame 21, so that the splicing is more stable when the rubber and plastic insulation board is installed at the use position. When the connecting main frame 21 is connected to the rubber and plastic main board 1 through the connecting seat 23 and the reinforcement plug post 24, the connection between the rubber and plastic board main shell 11 and the rubber and plastic board bottom shell 12 can be strengthened, thus ensuring more stable assembly of the rubber and plastic board main shell 11 and the rubber and plastic board bottom shell 12.

[0025] Furthermore, please refer to Figures 1 to 12, the reinforcing plate 4 includes a support housing 41. Inside the support housing 41, a rubber and plastic filling plate 42 and a reinforcing rib plate 43 are installed. The rubber and plastic filling plate 42 and the reinforcing rib plate 43 are closely attached to the outer sides of the connecting seat 23 and the reinforcing connecting frame 25. During use, the support capacity is strengthened by the reinforcing rib plate 43, and the rubber and plastic filling plate 42 ensures the heat preservation capacity of the plate.

The reinforcing rib plate 43 is an aluminum alloy strip, which is cross-embedded at an interval of 50 - 80 mm. Moreover, the structures of the rubber and plastic plate main shell 11 and the rubber and plastic plate bottom shell 12 are the same as that of the support housing 41. The fireproof ability is strengthened through the outer fireproof housing 411 during use.

[0026] For the reinforcing plate 4 adopting the above technical solution, the support capacity is strengthened by the reinforcing rib plate 43 during use, which ensures the support during the installation and use of the plate and reduces the phenomenon of deformation. The outer fireproof housing 411 and the rubber and plastic plate body 412 cooperate to form the support housing 41, the rubber and plastic plate main shell 11 and the rubber and plastic plate bottom shell 12, strengthening the fireproof ability while ensuring heat preservation.

[0027] The working principle and usage process of the present invention: During assembly, the connecting seat 23 is snap-fitted and installed inside the reinforcing plate 4, and the reinforcing plug post 24 is inserted into the reinforcing card slot 232. The heat preservation layer board 3 and the reinforcing plate 4 are installed inside the rubber and plastic plate bottom shell 12, and the reinforcing plug post 24 is fixed on the rubber and plastic plate bottom shell 12 through bolts. Then, the rubber and plastic plate bottom shell 12 is installed inside the rubber and plastic plate main shell 11. The auxiliary connecting plate 22 is snap-fitted into the connecting slot 222, and the connecting card plate 223 is installed in the connecting slot 221 and fixed with screws. During installation and use, the rubber and plastic main boards 1 can be connected through the connecting mechanism 2. The connecting plug post 212 passes through the rubber and plastic plate main shell 11 and is inserted into the installation slot 231. The elastic force of the pushing spring 242 is used to push the reinforcing plug 244 to be snap-fitted into the connecting card slot 213 on the connecting plug post 212 for limiting. Then, screws pass through the connecting plug post 212 and are fixed to the reinforcing plate 4. During splicing connection, the connection between the rubber and plastic plate main shell 11 and the rubber and plastic plate bottom shell 12 can be strengthened, thus ensuring more stable installation and use.
