Description

Technical Field

[0001] This utility model relates to the field of color steel plate technology, and more specifically, it relates to a high-strength color steel plate with polyurethane filler. Background Technology

[0002] Color steel sheet is a type of steel sheet with an organic coating. It can be divided into single sheet, composite sheet, floor decking, etc. It is lightweight, easy to install, and low in cost, and is widely used in public buildings, factories, prefabricated houses and integrated houses.

[0003] However, conventional color steel sheets are relatively thin and light. If there is not enough supporting structure when installing color steel sheets, they are prone to sagging and deformation due to their own weight. Furthermore, when color steel sheets bear a large weight or are subjected to external forces, they are prone to deformation, such as when excessively heavy equipment or goods are placed on them, or when people walk on the roof of the color steel sheet or when snow accumulates. This affects the performance and poses certain safety hazards.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-strength color steel plate with polyurethane filler.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a polyurethane-filled high-strength color steel plate, comprising a front panel and a bottom plate arranged correspondingly on the top and bottom, wherein a plurality of reinforcing components are arranged in an array between the bottom plate and the front panel, and a plurality of receiving cavities one and a plurality of receiving cavities two are formed between the plurality of reinforcing components and the front panel and the bottom plate, wherein buffer blocks one and buffer blocks two are respectively provided in the receiving cavities one and the receiving cavities two, and both buffer blocks one and buffer blocks two are provided with a plurality of through slots, wherein the reinforcing components include a support plate one and two support plates two, wherein the support plate one is slidably connected between the two support plates two along the thickness direction of the front panel.

[0007] The present invention is further configured such that: the top surface of the first support plate is fixedly connected to the side of the panel near the bottom plate, and the bottom surface of the second support plate is fixedly connected to the side of the bottom plate near the panel.

[0008] The present invention is further configured such that: the length and width of the first support plate are the same as the length and width of the second support plate, the lengths of the first buffer block, the second buffer block, and the first support plate are the same, and the width of the first support plate is less than the thickness of the first buffer block.

[0009] The present invention is further configured such that: the two sides of the first buffer block abut against the planes of the bottom plate and the front plate respectively, and the two sides of the second buffer block abut against the bends of the front plate and the bottom plate respectively.

[0010] The present invention is further configured such that the width of buffer block one and buffer block two is smaller than the width of receiving cavity one and receiving cavity two, respectively, and the two sides of support plate one abut against the sides of the two support plates two that are close to each other.

[0011] The present invention is further configured such that: the first buffer block and its internal through grooves, and the second buffer block and its internal through grooves are all integrally formed by injection molding of polyurethane material, and the surfaces of the base plate and the panel are coated with a topcoat paint.

[0012] In summary, this utility model has the following beneficial effects: when subjected to impact, the polyurethane material can absorb and disperse energy through deformation, so that the several buffer blocks I and several buffer blocks II can play a good buffering role when the panel and the base plate are subjected to force. When the base plate and the panel are compressed by a large force and abut against the sides of the several support plates I and several support plates II, the several support plates I and several support plates II can provide a good support effect for the panel and the base plate, thereby reducing the possibility of deformation of the color steel plate during use and improving the strength of the color steel plate.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example: A high-strength color steel plate with polyurethane filler, such as Figure 1 and Figure 2As shown, the structure includes a front panel 1 and a base plate 2 arranged vertically. Both the front panel 1 and the base plate 2 have corrugated sections on the same side. When the front panel 1 or the base plate 2 is subjected to external force, the corrugations can share and transfer the load, thereby improving the bending resistance and overall rigidity of the base plate 2 or the front panel 1. Both the front panel 1 and the base plate 2 are made of 0.5mm thick hot-dip galvanized steel sheets, and their surfaces are pre-treated to remove impurities such as oil and rust, which improves the surface activity of the front panel 1 and the base plate 2 and enhances the adhesion of subsequent coatings. A topcoat is applied to the surface of the pre-treated hot-dip galvanized steel sheet. The topcoat forms a protective layer on the surface of the base plate 2 or the front panel 1, making the surface of the base plate 2 or the front panel 1 less susceptible to damage when subjected to friction or impact. It also blocks the corrosion of external factors such as ultraviolet rays and rainwater, achieving good weather resistance. This allows the base plate 2 or the front panel 1 to maintain the structural strength and stability during long-term outdoor use.

[0021] like Figures 1-5 As shown, several reinforcing components 3 are arranged in an array between the base plate 2 and the panel 1. These reinforcing components 3, along with the panel 1 and the base plate 2, enclose several receiving cavities 1 4 and several receiving cavities 2 5. Each receiving cavity 1 4 and receiving cavity 2 5 contains a buffer block 1 6 and a buffer block 2 7, respectively. Both buffer blocks 1 6 and 2 7 have several through slots 8. Buffer block 1 6 and its internal through slots 8, and buffer block 2 7 and its internal through slots 8, are integrally formed by injection molding of polyurethane material. The two sides of buffer block 1 6 abut against the planes of the base plate 2 and the panel 1, respectively. The two sides of buffer block 2 7 abut against the bends of the panel 1 and the base plate 2, respectively. The polyurethane material has good elasticity and can... When subjected to stress, energy is absorbed and dispersed through deformation. Several through grooves 8 provide sufficient deformation space for buffer block 6 and buffer block 7, so that the buffer blocks 6 and buffer blocks 7 can play a good buffering role when the panel 1 and the base plate 2 are subjected to stress. The buffer blocks 6 and buffer blocks 7 are glued and fixed between the panel 1 and the base plate 2, which can support the panel 1 and the base plate 2. The buffer blocks 6, buffer blocks 7, base plate 2 and panel 1 can share the stress. The base plate 2 and panel 1 mainly bear bending and tensile stress, while the buffer blocks 6 and buffer blocks 7 mainly bear compressive stress, thereby improving the overall strength and load-bearing capacity of the color steel plate.

[0022] like Figures 1-5As shown, the reinforcing component 3 includes a rectangular support plate 301 and two rectangular support plates 302. The top surface of support plate 301 is welded and fixed to the side of panel 1 near the bottom plate 2, and the bottom surface of support plate 302 is welded and fixed to the side of bottom plate 2 near panel 1. The length and width of support plate 301 are the same as those of support plate 302. Buffer block 6, buffer block 7, and support plate 301 have the same length, and the width of support plate 301 is less than the thickness of buffer block 6. This design ensures that, when the color steel sheet is not under stress, there is a certain gap between support plate 1 (301) and base plate 2, and a certain gap between support plate 2 (302) and panel 1, thus providing space for support plate 1 (301) and support plate 2 (302) to move. The widths of buffer blocks 1 (6) and 2 (7) are smaller than the widths of receiving cavities 1 (4) and 2 (5), respectively, ensuring that there are gaps between each of the buffer blocks 1 (6) and 2 (7) and each of the support plates 2 (302), preventing gaps between support plate 1 (301) and support plate 2 (302) 302. During the movement, the support plate 301 abuts against buffer block 6 and buffer block 7, thus ensuring the movement of support plate 301 and support plate 302. The two sides of support plate 301 abut against the adjacent sides of the two support plates 302, allowing support plate 301 to slide and connect between the two support plates 302 along the thickness direction of panel 1. When the base plate 2 and panel 1 are subjected to a large force pressing against buffer block 6 and buffer block 7, several support plates 301 move along the direction closer to the base plate 2 with panel 1. The movement causes several support plates 301 to abut against the base plate 2 on the side away from the panel 1, and several support plates 302 to move along the base plate 2 towards the panel 1, causing the side of several support plates 302 away from the base plate 2 to abut against the panel 1. The support plates 301 and 302 are made of aluminum alloy, which is lightweight and high-strength. Thus, the support plates 301 and 302 can provide good support for the panel 1 and the base plate 2, reducing the possibility of deformation of the color steel plate under stress.

[0023] Working principle: Several buffer blocks 6 and 7 made of polyurethane material can absorb and disperse energy through deformation when subjected to force. Several through grooves 8 provide sufficient deformation space for buffer blocks 6 and 7. By filling several buffer blocks 6 and 7 between the panel 1 and the base plate 2, the panel 1 and the base plate 2 can play a good buffering role when subjected to force. When the base plate 2 and the panel 1 are subjected to a large force to squeeze the buffer blocks 6 and 7, several support plates 301 move with the panel 1 in the direction close to the base plate 2, so that the side of several support plates 301 away from the panel 1 abuts against the base plate 2. Several support plates 302 move with the base plate 2 in the direction close to the panel 1, so that the side of several support plates 302 away from the base plate 2 abuts against the panel 1, thereby supporting the panel 1 and the base plate 2.
