Description

Technical Field

[0001] This utility model relates to the field of engineering technology, and mainly to a wear-resistant and impact-resistant color steel plate. Background Technology

[0002] Early color steel sandwich panels mainly relied on screws or glue for fixing. Screw connections had two major drawbacks: first, they could easily damage the waterproof layer by penetrating the panel, leading to the risk of leakage; second, they were inefficient to install, requiring drilling holes at each point for fixing, which was time-consuming and labor-intensive, especially in large-scale construction. Glue bonding, on the other hand, faced the problem of insufficient durability, and was prone to delamination after long-term use. Moreover, chemical adhesives may release harmful substances, which is not in line with environmental protection trends. With the rise of prefabricated buildings, the demand for modular construction teams to quickly install panels and repeatedly disassemble them has surged.

[0003] Therefore, utility model application CN202321596293.5 discloses a connection structure for color steel sandwich panels, including two color steel sandwich panel bodies. The two color steel sandwich panel bodies are interlocked to form a cavity. A connector is provided between the two color steel sandwich panel bodies. The connector includes sealing blocks that are fitted at both ends of the cavity. Each sealing block has an insertion rod extending into the cavity. Multiple U-shaped blocks are fitted from top to bottom on the insertion rod. The ends of the multiple U-shaped blocks are staggered and fixed to the side walls of the two color steel sandwich panel bodies. Each top end of the insertion rod relative to both sides of the color steel sandwich panel body has a locking block, which engages with the U-shaped block located near the top end of the insertion rod. This utility model connector can strengthen the connection stability between the two color steel sandwich panel bodies, improve the sealing performance, and also prevent pests such as rats or cockroaches from entering the cavity between the two color steel sandwich panel bodies and causing damage to the color steel sandwich panel bodies.

[0004] However, the applicant found that the above technology still has shortcomings: 1. The sealing block set in the connecting cavity restricts thermal expansion and contraction, which leads to structural deformation, cannot provide buffer space, and hinders air permeability, which aggravates the accumulation of condensate. 2. The safety risk is high. When encountering strong winds, it is easy to be lifted or torn by wind pressure, or even cause large-scale collapse, resulting in casualties and property damage.

[0005] Therefore, there is an urgent need for a concealed locking color steel plate that is highly secure, has strong connection stability, and is aesthetically pleasing. Utility Model Content

[0006] To address the above issues, a concealed locking color steel plate with high security, strong connection stability, and aesthetic appeal was developed. The connection stability is effectively improved by the interlocking of the female and male ends of the latch. At the same time, the water-retaining edge not only further enhances the connection stability but also improves the waterproof effect.

[0007] To achieve the above objective, the present utility model provides the following technical solutions: A wear-resistant and impact-resistant color steel plate, comprising: an outer steel plate, a heat-insulating inner core and an inner steel plate; Side steel plates are arranged on both sides of the outer steel plate and the inner steel plate, the long edges on both sides of the outer steel plate extend downward and are folded to be fixedly connected to the top ends of the side steel plates, the bottom ends of the two side steel plates extend downward and are folded to be fixedly connected to the inner steel plate to form an outer frame, and the heat-insulating inner core is fixedly connected into the outer frame by glue to form a color steel sandwich panel; One side of the outer frame is bent to form a female snap end, the other side of the outer frame is bent to form a male snap end, and adjacent color steel sandwich panels are snap-connected in the vertical direction through the female snap end and the male snap end.

[0008] As an improvement, two sets of outer folded snap edges are arranged on the female snap end, and the two sets of outer folded snap edges are arranged in parallel.

[0009] As an improvement, two sets of inner folded snap edges are arranged on the male snap end, the two sets of inner folded snap edges are arranged in parallel, and the inner folded snap edges move in the vertical direction to snap into the outer folded snap edges for fixed connection.

[0010] As an improvement, a connection gap is formed inside when the female snap end and the male snap end are mutually snapped together.

[0011] As an improvement, both the outer steel plate and the inner steel plate are in a flat plate shape, and the outer steel plate and the inner steel plate are arranged in parallel.

[0012] As an improvement, the heat-insulating inner core is formed by splicing an upper inner core and a lower inner core, a plurality of sets of arc-shaped grooves are arranged on both the upper inner core and the lower inner core, and the inner arc-shaped grooves form an elliptical groove when the upper inner core and the lower inner core are spliced.

[0013] As an improvement, two sets of protruding blocks are arranged on the upper inner core, two sets of grooves are arranged on the lower inner core, and the protruding blocks and the grooves are mutually engaged.

[0014] As an improvement, a water retaining edge is further arranged at the inner connection position of adjacent color steel sandwich panels, the water retaining edge is in a shape of a Chinese character "ji" (several), and the water retaining edge is fixedly connected with the color steel sandwich panels by screws.

[0015] The beneficial effects of the present utility model are as follows: (1) The precise bending of the female snap end and the male snap end in the present utility model enables convenient operation through the vertical snap connection manner, which can complete splicing quickly, and the tight fit effectively reduces the ingress of rainwater and dust, not only improving the sealing performance but also being aesthetically pleasing. At the same time, the splicing gap reserves space for thermal expansion and cold contraction, avoiding structural deformation caused by temperature changes; (2) The upper inner core and the lower inner core of the heat insulation inner core in this utility model are divided into an upper inner core and a lower inner core. The ingenious design of the arc groove and the elliptical groove enhances the stability of the structure. Secondly, the engagement of the protrusion and the groove further improves the splicing firmness and facilitates the assembly between the upper inner core and the lower inner core. This significantly improves the heat insulation effect and production efficiency and effectively extends the service life. (3) The water-blocking edge provided at the inner connection of the adjacent color steel sandwich panels in this utility model is tightly fitted to the connection seam to form an effective waterproof barrier. Finally, it is fixed by screws to ensure that it will not loosen for a long time and can effectively prevent rainwater from seeping into the room. (4) The outer frame of this utility model is formed by the outer steel plate, inner steel plate and side steel plate of the same material through multiple pressing and bending processes. The overall structure is stable, making it less prone to deformation during transportation and installation, and can effectively resist external impact.

[0016] In summary, this utility model provides a concealed locking color steel plate with high security, strong connection stability, and aesthetic appeal, effectively improving the convenience and stability of connection, outstanding heat and sound insulation, and reliable waterproofing.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] Example 1: like Figures 1 to 9 As shown, a wear-resistant and impact-resistant color steel plate includes: Outer steel plate 1, heat-insulating inner core 2, and inner steel plate 3; Both sides of the outer steel plate 1 and the inner steel plate 3 are provided with side steel plates 4. The long sides of the outer steel plate 1 extend downward and are pressed and folded to the top of the side steel plate 4 for fastening. The bottom ends of the side steel plates 4 extend downward and are pressed and folded to the inner steel plate 3 for fastening, forming an outer frame 5. The heat-insulating inner core 2 is fixedly connected to the outer frame 5 with glue to form a color steel sandwich panel 10. One side of the outer frame 5 is bent to form a female buckle end 51, and the other side of the outer frame 5 is bent to form a male buckle end 52. The adjacent color steel sandwich panels 10 are connected by snapping together with the female buckle end 51 and the male buckle end 52 in the vertical direction.

[0023] The female end 51 of the buckle is provided with two sets of outer buckle folds 511. The outer buckle folds 511 are long strips but their length does not exceed the long side of the outer frame 5. The two sets of outer buckle folds 511 are arranged in parallel.

[0024] The male end 52 of the buckle is provided with two sets of inner buckle folds 521. The inner buckle folds 521 are long strips but their length does not exceed the long side of the outer frame 5. The two sets of inner buckle folds 521 are arranged in parallel. The inner buckle folds 521 are moved vertically to buckle and be fixedly connected to the outer buckle folds 511.

[0025] When the female end 51 of the hook and the male end 52 of the hook are fastened together, a connection gap 53 is formed inside.

[0026] It should be noted that the outer buckle 511 of the female buckle end 51 and the inner buckle 521 of the male buckle end 52 are both precisely bent. Their parallel arrangement ensures uniform force during buckle connection. The buckle method along the vertical direction is convenient to operate and effectively hides the connection part, making the connection position aesthetically pleasing. At the same time, it can quickly complete the buckle splicing of adjacent color steel sandwich panels 10. The formation of the splicing gap 53 reserves space for the thermal expansion and contraction of the color steel sandwich panel 10, avoiding structural deformation due to temperature changes.

[0027] Both the outer steel plate 1 and the inner steel plate 3 are flat, and the outer steel plate 1 and the inner steel plate 3 are arranged in parallel.

[0028] It should be noted that both the outer steel plate 1 and the inner steel plate 3 are made of materials with good weather resistance and corrosion resistance. Their flat and parallel arrangement not only ensures the surface flatness of the color steel sandwich panel 10, facilitating subsequent decoration, but also evenly disperses external impact forces and improves the wind pressure resistance of the overall structure. The side steel plate 4 is made of the same material as the outer steel plate 1 and the inner steel plate 3. It is fastened to the outer steel plate 1 and the inner steel plate 3 through multiple pressing and folding processes to form the outer frame 5, which enhances the structural strength of the outer frame 5 and makes the color steel sandwich panel 10 less prone to deformation during transportation and installation.

[0029] The heat-insulating inner core 2 is composed of an upper inner core 21 and a lower inner core 22 spliced ​​together. Both the upper inner core 21 and the lower inner core 22 are provided with several sets of arc-shaped grooves 23, and when the upper inner core 21 and the lower inner core 22 are spliced ​​together, the arc-shaped grooves 23 inside are combined to form an elliptical groove 24.

[0030] Two sets of protruding blocks 211 are disposed on the upper inner core 21, and two sets of grooves 221 are disposed on the lower inner core 22, wherein the protruding blocks 211 and the grooves 221 are arranged to be mutually engaged.

[0031] It should be noted that the upper inner core 21 and the lower inner core 22 are made of flame-retardant rock wool material, which has excellent heat insulation and sound insulation properties. The engagement structure of the protruding blocks 211 and the grooves 221 not only facilitates the assembly of the two, but also increases the contact area between the upper and lower inner cores. Combined with the fixing effect of the adhesive, the firmness of the connection between the heat-insulating inner core 2 and the outer frame is further improved. The elliptical groove 24 formed by the arc-shaped grooves 23 forms an air heat insulation layer, which, in combination with the inherent properties of the heat insulation material, significantly enhances the thermal insulation effect of the color steel sandwich panel 10. The elliptical structural design can also disperse the pressure applied to the inner core and prolong the service life.

[0032] A water retaining edge 6 is further disposed at the inner connection position of adjacent color steel sandwich panels 10, the water retaining edge 6 is in a shape of a Chinese character "几", and the water retaining edge 6 is fixedly connected to the color steel sandwich panels 10 by screws.

[0033] It should be noted that the water retaining edge 6 is made of stainless steel. The "几" shape design enables it to closely fit the inner connection position of adjacent color steel sandwich panels 10 to form an effective waterproof barrier. The screw fixing mode ensures that the water retaining edge 6 will not become loose during long-term use, and can effectively prevent rainwater from seeping into the room through the connection gap even in severe weather such as heavy rain.

[0034] The above description is merely preferred embodiments of the present utility model, and is not intended to limit the present utility model.
