Description

Technical Field

[0001] This utility model belongs to the field of enamel steel plate technology, specifically, it relates to a shock-absorbing enamel steel plate structure. Background Technology

[0002] Traditionally, decorative panels for walls, columns, countertops, and ceilings were made of cement products, marble slabs, granite slabs, ceramic tiles, coated wallpaper, and gypsum board. However, some of these materials are expensive, others cannot withstand sun and rain, have poor thermal insulation and sound absorption, and some are too heavy, making installation inconvenient. Therefore, metal curtain wall panels, such as aluminum and steel panels, are now widely used due to their superior surface properties and aesthetic appeal. However, ordinary steel and aluminum single-panel designs lack internal shock-absorbing structures, resulting in poor assembly stability. Furthermore, because steel panels are relatively thin, they can only withstand small negative wind pressures and have weak impact resistance. They are also prone to fading, difficult to clean, and have poor thermal and sound insulation properties.

[0003] Therefore, there is an urgent need for a new type of enamel steel plate structure with good shock absorption and sound absorption properties. Utility Model Content

[0004] In view of this, the technical problem to be solved by this utility model is to provide a shock-absorbing enamel steel plate structure, which avoids the trouble of the previous metal curtain wall panels having no shock-absorbing structure in the middle, resulting in weak overall wind pressure resistance and poor stability during assembly.

[0005] To solve the above-mentioned technical problems, this utility model discloses a shock-absorbing enamel-lined steel plate structure, comprising:

[0006] The shock-absorbing core layer includes an intermediate rubber pad and metal mesh plates bonded to the front and rear sides of the intermediate rubber pad. The intermediate rubber pad has honeycomb holes.

[0007] Transition steel plates are fixed to the front and rear surfaces of the shock-absorbing core layer, respectively;

[0008] The corrugated substrates are welded to the surface of the transition steel plate. The corrugated substrates have a corrugated part in the center and a sealing part at the four edges. The corrugated part is set as a sine wave with crests and troughs. The transition steel plate is welded to the troughs. The sealing parts are welded to each other by aluminum beams. The aluminum beams are provided with multiple assembly holes.

[0009] A polyurethane liner is filled between the transition steel plate and the corrugations;

[0010] The surface of the waveform substrate is coated with an enamel layer.

[0011] According to one embodiment of the present invention, the sinusoidal waveform of the waveform section satisfies the following: wavelength is 20-50mm, amplitude is 5-15mm, and the ratio of amplitude to wavelength is 1:3 to 1:5.

[0012] According to one embodiment of the present invention, the welding of the transition steel plate and the trough is carried out by laser welding, the welding point spacing is 10-20mm, and the weld depth-to-width ratio is not less than 3:1.

[0013] According to one embodiment of the present invention, the thickness of the waveform substrate is greater than the thickness of the transition steel plate.

[0014] According to one embodiment of the present invention, the thickness of the above-mentioned shock-absorbing core layer is 4-8mm.

[0015] Compared with the prior art, the present invention can achieve the following technical effects:

[0016] By combining the middle rubber pad of the shock-absorbing core layer with the metal mesh plate, and with the sinusoidal waveform design of the corrugated substrate, vibration energy can be absorbed efficiently; the polyurethane lining filler enhances the overall structure and helps to improve the shock absorption effect.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the above-mentioned technical effects at the same time. Attached Figure Description

[0025] In one embodiment of this utility model, the thin corrugated steel plate stamped from the corrugated substrate 30 has a corrugated part in the center and horizontal sealing parts around the edges. The corrugated substrate 30 serves as the inner and outer layers, and the sealing parts at the edges are welded together by aluminum beams 50 to form a frame shape. The inner cavity in the middle is filled with a shock-absorbing structure.

[0026] Specifically, a transition steel plate 20 is first welded to the inner surface of the corrugated substrate 30 for reinforcement. Simultaneously, the cavities formed by the remaining corrugated surfaces are filled with a polyurethane liner 40 to enhance the overall structural integrity and improve the damping effect. A damping core layer 10 is then filled between the transition steel plates 20. The damping effect is further enhanced by the combination of the intermediate rubber pad 11 and the metal mesh plate 12 within the damping core layer 10. The intermediate rubber pad 11 is a rubber sheet, preferably made of butyl rubber, with hexagonal honeycomb holes of 8mm diameter and 1.5mm wall thickness. The metal mesh plate 12 is made of hot-dip galvanized carbon steel with a mesh size of 15mm × 15mm, and is bonded to the front and rear sides of the intermediate rubber pad 11 to provide performance. Preferably, the damping core layer 10 has a thickness of 4-8mm.

[0027] In addition, the surface of the waveform substrate 30 is also coated with an enamel layer, which is formed by spraying and sintering enamel glaze to improve weather resistance.

[0028] In a preferred embodiment, the sinusoidal waveform of the waveform portion of the waveform substrate 30 satisfies the following conditions: wavelength is 20-50mm, amplitude is 5-15mm, and the ratio of amplitude to wavelength is 1:3 to 1:5, which can efficiently absorb vibration energy and enhance the anti-vibration effect.

[0029] The transition steel plate 20 is welded to the trough using laser welding, with a weld spot spacing of 10-20mm and a weld depth-to-width ratio of not less than 3:1 to ensure stability.

[0030] In addition, the thickness of the corrugated substrate 30 is greater than that of the transition steel plate 20 to ensure the strength of the outer plate surface.

[0031] In summary, this utility model combines the middle rubber pad 11 of the shock-absorbing core layer 30 with the metal mesh plate 12, and with the sinusoidal waveform design of the waveform substrate 30, which can efficiently absorb vibration energy; the polyurethane lining 40 fills and enhances the overall structure, and helps to improve the shock absorption effect.
