Description

Technical Field

[0001] This utility model relates to the field of PVC board technology, and in particular to weather-resistant reinforced PVC board. Background Technology

[0002] Weather-resistant reinforced PVC sheet is a type of polyvinyl chloride (PVC) sheet with strong resistance to ultraviolet rays, oxidation, and high and low temperatures. It is typically used outdoors or in harsh environments. Based on PVC, it incorporates weather-resistant reinforcing materials, allowing it to maintain good performance and appearance even after prolonged exposure to sunlight, rain, and other environmental conditions. Due to its excellent environmental resistance, weather-resistant reinforced PVC sheet is widely used in construction, transportation, advertising, and other industries, providing reliable durability and stability.

[0003] In practical use, existing weather-resistant reinforced PVC boards are not easy to assemble in multiple groups, making it difficult to improve installation efficiency.

[0004] A search of existing patents revealed an impact-resistant PVC board (publication number: CN220081859U). This invention addresses the limitation of traditional PVC boards in terms of area. If a larger area of ​​PVC board is required for a given task, a custom-made larger board is necessary, reducing work efficiency and extending working time. The proposed design includes a first PVC board, with a second PVC board positioned on one side. A gap groove is formed between the first and second PVC boards, and a flexible connecting post is positioned within the groove. One end of the flexible connecting post is bonded to the first PVC board, and the other end, away from the first PVC board, is bonded to the second PVC board. The design also includes a mating connecting plate positioned at one end of each PVC board.

[0005] While the aforementioned patents have solved the problem of limited area in traditional PVC boards, they are not conducive to flame retardancy and are difficult to effectively resist combustion or slow the spread of fire in the event of a fire. Utility Model Content

[0006] The technical problem to be solved by this utility model is as follows: to provide a weather-resistant reinforced PVC board with high practicality and simple structure that can be operated easily, thereby solving the problem mentioned in the background art that it is not convenient to retard flames and is difficult to effectively resist combustion or slow down the spread of fire when a fire occurs.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A weather-resistant reinforced PVC board includes a substrate and a protective plate 1. A reinforcing plate is fixedly connected to the surface of the substrate, and a splicing assembly is fixedly connected to the top of the reinforcing plate. Several sets of flame-retardant components are fixedly connected to the surface of the protective plate 1. A protective plate 2 is fixedly connected to one side of the flame-retardant components. A protective panel is fixedly connected to the surface of the protective plate 2. The splicing assembly includes an insert plate fixedly connected to the top of the reinforcing plate, and two sets of locking strips are fixedly connected to both sides of the insert plate. The flame-retardant components include a partition plate fixedly connected to the surface of the protective plate 1, and a flame-retardant layer is fixedly connected inside the partition plate.

[0009] As a further embodiment of this utility model, a shock-absorbing layer is fixedly connected to the surface of the reinforcing plate. The shock-absorbing layer is made of polyethylene foam, which facilitates shock absorption and cushioning.

[0010] As a further embodiment of this utility model, a sound insulation layer is fixedly connected to the surface of the shock-absorbing layer. The sound insulation layer is made of sound-insulating cotton, which helps to reduce noise transmission.

[0011] As a further embodiment of this utility model, the interior of the reinforcing plate is provided with several sets of reinforcing ribs, and the flame-retardant layer is made of ceramic powder material, which can effectively resist combustion or slow down the spread of fire.

[0012] As a further embodiment of this utility model, the back of the substrate is fitted with two sets of locking posts, and a mounting bracket is fixedly connected to one side of each locking post. The surface of the mounting bracket is provided with two sets of mounting holes, which facilitates support and installation.

[0013] As a further embodiment of this utility model, sealing strips are fixedly connected to the top and bottom of the partition, and grooves are provided on the surface of the protective panel, with the sealing strips facilitating increased sealing.

[0014] As a further embodiment of this utility model, two sets of clamping plates are fixedly connected to the bottom of the substrate. The clamping plates have slots inside that are adapted to the card strips, and the slots facilitate the card strips to be inserted and positioned.

[0015] The beneficial effects of this utility model are:

[0016] 1. This weather-resistant reinforced PVC board, through the setting of flame-retardant components, allows the flame to burn through the protective panel and then ignite the flame-retardant layer during a fire. The temperature generated by the combustion causes the flame-retardant layer to melt. Since the flame-retardant layer is made of ceramic powder, it melts and forms a ceramic oxygen-insulating film that adheres to the surface of the protective board, isolating the transfer of oxygen and heat and preventing further combustion of the material. This achieves the effect of flame retardancy, and can more effectively resist combustion or slow down the spread of fire during a fire.

[0017] 2. This weather-resistant reinforced PVC board, through the splicing component, allows for easy assembly of multiple PVC boards by inserting the insert plate on the base plate into the space between two sets of clamping plates at the bottom of another base plate. Due to the elasticity of the clamping plates, the clamping plates deform slightly under force when the insert plate is inserted. When fully inserted, the locking strip on the insert plate engages with the slot inside the clamping plate for limiting, thereby achieving convenient assembly of multiple PVC boards, shortening installation time, reducing installation costs, enhancing the flexibility of the PVC board structure, and improving installation efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] like Figure 1-4As shown, the weather-resistant reinforced PVC board includes a base plate 1 and a protective plate 2. A reinforcing plate 3 is fixedly connected to the surface of the base plate 1, and a splicing component 4 is fixedly connected to the top of the reinforcing plate 3. The splicing component 4 allows for convenient assembly of multiple PVC boards, shortening installation time, reducing installation costs, enhancing the flexibility of the PVC board structure, and improving installation efficiency. Several flame-retardant components 5 are fixedly connected to the surface of the protective plate 2. The flame-retardant components 5 achieve the effect of flame retardancy, effectively resisting combustion or slowing the spread of fire in the event of a fire. A protective plate 2 6 is fixedly connected to one side of the flame-retardant component 5, and a protective panel 7 is fixedly connected to the surface of the protective plate 2 6. The splicing component 4 includes an insert plate 401 fixedly connected to the top of the reinforcing plate 3, and two sets of clips 402 fixedly connected to both sides of the insert plate 401. The flame-retardant component 5 includes a partition plate 501 fixedly connected to the surface of the protective plate 2, and a flame-retardant layer 502 is fixedly connected inside the partition plate 501.

[0026] like Figure 4 As shown, a shock-absorbing layer 8 is fixedly connected to the surface of the reinforcing plate 3. The shock-absorbing layer 8 is made of polyethylene foam. The shock-absorbing layer 8 plays a role in shock absorption and buffering.

[0027] like Figure 4 As shown, a sound insulation layer 9 is fixedly connected to the surface of the shock-absorbing layer 8. The sound insulation layer 9 is made of sound insulation cotton. The sound insulation layer 9 reduces the transmission of noise.

[0028] like Figure 4 As shown, the interior of the reinforcing plate 3 is provided with several sets of reinforcing ribs 10, and the flame retardant layer 502 is made of ceramic powder. Through the setting of the flame retardant layer 502, it plays an effective role in resisting combustion or slowing down the spread of fire.

[0029] like Figure 2 As shown, two sets of latches 11 are snapped onto the back of the substrate 1. A mounting bracket 12 is fixedly connected to one side of the latches 11. Two sets of mounting holes are opened on the surface of the mounting bracket 12. The mounting bracket 12 facilitates the support and installation.

[0030] like Figure 3 As shown, sealing strips 13 are fixedly connected to the top and bottom of the partition 501, and grooves are provided on the surface of the protective panel 7. The sealing strips 13 are used to increase the sealing performance.

[0031] like Figure 4 As shown, two sets of clamping plates 14 are fixedly connected to the bottom of the base plate 1. The clamping plates 14 have slots that are compatible with the card strip 402. The slots facilitate the insertion and positioning of the card strip 402.

[0032] The working principle of this utility model is as follows: In use, the insert plate 401 on the substrate 1 is inserted between the two sets of clamping plates 14 at the bottom of another set of substrate 1. Since the clamping plates 14 have a certain elasticity, when the insert plate 401 is inserted into the clamping plates 14, the clamping plates 14 are slightly deformed by force. When fully inserted, the locking strip 402 on the insert plate 401 is locked into the locking groove inside the clamping plates 14 for limiting. In the event of a fire, after the flame burns through the protective panel 7, it burns the flame-retardant layer 502. The temperature generated by the combustion causes the flame-retardant layer 502 to melt. Since the flame-retardant layer 502 is made of ceramic powder, it melts to form a ceramic oxygen-insulating film, which adheres to the surface of the protective panel 2, isolating the transfer of oxygen and heat, and preventing further combustion of the material.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
