Description

Technical Field

[0001] The present invention relates to the technology of color steel composite panels, and particularly to a multi-core layer color steel composite panel. Background Art

[0002] Color steel composite panels are widely used in the fields of industrial and civil buildings due to their advantages such as light weight, high strength, and convenient installation.

[0003] Existing color steel composite panels usually have a single-core layer structure and are difficult to achieve high levels in terms of heat insulation, sound insulation, noise reduction, fire prevention, and flame retardancy at the same time. For example, traditional color steel composite panels with polystyrene as the core layer have good heat insulation effect but poor fire performance; color steel composite panels with rock wool core materials have excellent fire performance but limited sound insulation effect. In addition, the connection strength between the core layer and the color steel plate of existing color steel composite panels is insufficient, and delamination is likely to occur during long-term use, affecting the service life and overall performance. At the same time, with the development of the construction industry towards green and intelligent directions, higher requirements are also put forward for building materials in terms of environmental protection and functional integration. Existing color steel composite panels are difficult to meet the new demands of the industry development. Summary of the Invention

[0004] The purpose of the present invention is to provide a multi-core layer color steel composite panel to solve the above deficiencies in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A multi-core layer color steel composite panel includes an upper color steel plate and a lower color steel plate. Multiple groups of core layers are arranged between the upper color steel plate and the lower color steel plate, and polyurethane adhesive layers are arranged between the upper color steel plate and the adjacent core layer, between the lower color steel plate and the adjacent core layer, and between adjacent two groups of core layers; The core layer includes a first heat insulation core layer, a sound insulation damping core layer, a fire prevention and flame retardant core layer, and a second heat insulation core layer arranged in sequence from the directions of the upper color steel plate and the lower color steel plate, and the first heat insulation core layer is connected to the upper color steel plate; Side seal plates are arranged between the long side edges on both sides of the upper color steel plate and the lower color steel plate, and end plates are arranged between the short side edges on both sides of the upper color steel plate and the lower color steel plate.

[0007] Further, the thickness of the first heat insulation core layer is 20 mm, the thickness of the sound insulation damping core layer is 7 mm, and the thickness of the fire prevention and flame retardant core layer is 25 mm.

[0008] Furthermore, bending portions are provided on both sides of the upper color steel plate and the lower color steel plate. The two bending portions on the same side are symmetrically arranged. Guide grooves are formed between the bending portions and the upper color steel plate and the lower color steel plate respectively. The shapes and dimensional specifications of the upper and lower ends of the side sealing plate are adapted to the guide grooves.

[0009] Furthermore, the length values of the first heat-insulating core layer, the sound-insulating damping core layer, the fireproof and flame-retardant core layer, and the second heat-insulating core layer are the same. The length values of the upper color steel plate, the lower color steel plate, and the side sealing plate are the same. And the length value of the first heat-insulating core layer is less than the length value of the upper color steel plate. End embedded grooves are formed at the ends of the upper color steel plate, the lower color steel plate, and the two side sealing plates in the assembled state. The thickness value and shape of the embedded groove are adapted to the end plate.

[0010] Furthermore, extension plates are provided at both ends of the end plate. Connecting plates adapted to the extension plates are provided on the side surface of the side sealing plate. The extension plates and the connecting plates are connected by rivets.

[0011] Furthermore, the side surfaces of the extension plates and the connecting plates are flush with the side surface of the upper color steel plate.

[0012] Furthermore, inner guide plates are symmetrically arranged at both ends of the surface of one side sealing plate, and outer guide plates are symmetrically arranged on the surface of the other side sealing plate.

[0013] Furthermore, the distance value between the inner walls on the opposite sides of the two outer guide plates is adapted to the distance value between the inner walls on the mutually separated sides of the two inner guide plates.

[0014] Furthermore, the width value of the inner guide plate is the same as the width value of the outer guide plate. And the width value of the inner guide plate is twice the distance value from the outer side surface of the side sealing plate to the outer side surface end of the upper color steel plate. The height value of the inner guide plate is adapted to the distance value between the upper and lower groups of bending portions.

[0015] Compared with the prior art, a multi-core layer color steel composite board provided by the present invention has the following beneficial effects: 1.

[0016] 2. For this multi-core layer color steel composite board, through the mutual cooperation among the bending part, the guide groove and the embedded groove, the splicing between the side sealing plate and the short plate and the upper color steel plate and the color steel plate can be made more convenient.

For this multi-core layer color steel composite board, through the setting of the inner guide plate and the outer guide plate, it can quickly guide the splicing during the splicing process of two groups of color steel composite boards, so that the combined connection process of the color steel composite board is more convenient and fast.

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Example 1: Please refer to Figures 1-7 , a multi-core layer color steel composite board, including an upper color steel plate 1 and a lower color steel plate 101. A plurality of groups of core layers 2 are arranged between the upper color steel plate 1 and the lower color steel plate 101, and polyurethane adhesive layers 3 are arranged between the upper color steel plate 1 and the adjacent core layer 2, between the lower color steel plate 101 and the adjacent core layer 2, and between two adjacent core layers 2.

[0023] It should be added that both the first thermal insulation core layer 21 and the second thermal insulation core layer 24 are made of extruded polystyrene foam boards, and their thicknesses are set to 20 mm, so that they can effectively prevent heat transfer, provide good thermal insulation and heat preservation effects for the composite board, reduce the heat exchange between indoors and outdoors, and maintain the stability of the indoor temperature. In addition, the thicknesses of the first thermal insulation core layer 21 and the second thermal insulation core layer 24 can be flexibly adjusted according to the needs of the actual application area, so that they can provide continuous and stable thermal insulation and heat preservation effects for the building regardless of whether it is in a severe cold or hot environment; The sound insulation and damping core layer 22 is made of a rubber-modified asphalt damping material, and its thickness is set to 7 mm, so that the sound insulation and damping core layer 22 has high damping characteristics, can absorb and dissipate sound wave energy when sound waves propagate, thereby effectively reducing noise, can reduce the interference of external noise on the indoor environment, and can also prevent indoor sound from leaking out. And by setting its thickness to 7 mm, while effectively ensuring the sound insulation effect, it will not excessively increase the overall thickness of the composite board, which is convenient for subsequent installation and construction; The fireproof and flame-retardant core layer 23 is made of a rock wool board coated with an intumescent fireproof coating, and its thickness is set to 25 mm. Since the rock wool board itself has good fireproof performance, coating the rock wool board with an intumescent fireproof coating can rapidly expand to form a dense heat insulation layer when encountering fire, so as to cooperate with the rock wool board to further improve the fireproof and flame-retardant performance of the color steel composite board, can delay the spread of fire when a fire occurs, and thus provide more reliable fire protection; The polyurethane adhesive layer 3 is made of a polyurethane adhesive. The polyurethane adhesive is used to adhere between the core layers 2 and between the core layer 2 and the upper color steel plate 1 and the lower color steel plate 101, so that the connection tightness between the layers is better.

[0024] The core layer 2 includes a first thermal insulation core layer 21, a sound insulation and damping core layer 22, a fireproof and flame-retardant core layer 23, and a second thermal insulation core layer 24, which are arranged in sequence from the directions of the upper color steel plate 1 and the lower color steel plate 101, and the first thermal insulation core layer 21 is connected to the upper color steel plate 1.

[0025] Since the upper color steel plate 1 serves as the outer layer of the color steel composite plate and directly bears the influence of external environmental factors, the first heat-insulating core layer 21 is adjacent to the upper color steel plate 1 and can quickly block the heat from the outside from entering; the sound insulation and damping core layer 22 is arranged below the first heat-insulating core layer 21 and can effectively absorb and dissipate the sound wave energy transmitted through the first heat-insulating core layer 21; the fireproof and flame-retardant core layer 23 is arranged in the middle position and can play a fireproof and flame-retardant role in all directions in case of fire; the second heat-insulating core layer 24 is close to the lower color steel plate 101 and can further block the heat from being transmitted from below, and together with the first heat-insulating core layer 21, it forms a stable heat insulation system; the lower color steel plate 101 serves as the bottom layer and, together with the upper color steel plate 1, forms a protection for the internal core layer. Therefore, by sequentially arranging the upper color steel plate 1, the first heat-insulating core layer 21, the sound insulation and damping core layer 22, the fireproof and flame-retardant core layer 23, the second heat-insulating core layer 24, and the lower color steel plate 101 from top to bottom, the functions of each core layer 2 can be fully exerted, making the overall sound insulation, heat insulation, and fireproof performance of the color steel composite plate better, thereby significantly improving the overall safety and reliability of the color steel composite plate.

[0026] Side seal plates 102 are arranged between the two long side edges of the upper color steel plate 1 and the lower color steel plate 101, and end plates 103 are arranged between the two short side edges of the upper color steel plate 1 and the lower color steel plate 101.

[0027] Through the arrangement of the side seal plates 102 and the end plates 103, not only can each core layer 2 be protected, but also the overall structural strength of the color steel composite plate can be improved, extending the service life of the color steel composite plate.

[0028] Embodiment 2: Please refer to Figure 3 , this embodiment provides a technical solution on the basis of the above embodiment: bending portions 4 are arranged on both sides of the upper color steel plate 1 and the lower color steel plate 101, and the two bending portions 4 on the same side are symmetrically arranged. Guide grooves 41 are formed between the bending portions 4 and the upper color steel plate 1 and the lower color steel plate 101 respectively. The shapes and dimensional specifications of the upper and lower ends of the side seal plates 102 are adapted to the guide grooves 41.

[0029] It should be added that the length values of the first heat-insulating core layer 21, the sound insulation and damping core layer 22, the fireproof and flame-retardant core layer 23, and the second heat-insulating core layer 24 are the same, the length values of the upper color steel plate 1, the lower color steel plate 101, and the side seal plates 102 are the same, and the length value of the first heat-insulating core layer 21 is less than the length value of the upper color steel plate 1. End-embedded grooves 42 are formed at the ends of the upper color steel plate 1, the lower color steel plate 101, and the two side seal plates 102 in the assembled state. The thickness value and shape of the end-embedded grooves 42 are adapted to the end plates 103, so that each connection is relatively flat after assembly, facilitating the subsequent splicing and cooperation between multiple groups of color steel composite plates, and also facilitating the connection between the color steel composite plate and other supporting members.

[0030] Furthermore, extension plates 43 are provided at both ends of the end plate 103, and connecting plates 44 adapted to the extension plates 43 are provided on the side surfaces of the side seal plates 102. The extension plates 43 and the connecting plates 44 are connected by rivets, so that the connection stability among the upper color steel plate 1, the lower color steel plate 101, the side seal plates 102 and the end plate 103 is better.

[0031] In addition, the side surfaces of the extension plates 43 and the side surfaces of the connecting plates 44 are flush with the side surface of the upper color steel plate 1, so that there is enough space for the rivets to connect and fix the extension plates 43 and the connecting plates 44.

[0032] During installation, first insert the upper and lower ends of the side seal plate 102 into the upper and lower groups of guide grooves 41, and then push the side seal plate 102 to slide along the inner wall of the guide groove 41, so that the two ends of the side seal plate 102 are flush with the first heat preservation core layer 21. After that, embed the two end plates 103 into the inner embedding grooves 42 on both sides, and connect and fix the extension plates 43 and the connecting plates 44 on both sides by rivets, so that the side seal plate 102 and the end plate 103 can be stably connected and fixed to the upper color steel plate 1 and the lower color steel plate 101.

[0033] Embodiment 3: Please refer to Figure 4 , Figure 7 Based on the above embodiment, this embodiment provides a technical solution: inner guide plates 5 are symmetrically arranged at both ends of the surface of one side seal plate 102, and outer guide plates 51 are symmetrically arranged on the surface of the other side seal plate 102.

[0034] Moreover, the distance value between the inner walls of the two outer guide plates 51 facing each other is adapted to the distance value between the inner walls of the two inner guide plates 5 away from each other.

[0035] During the splicing process, by aligning the two inner guide plates 5 on one group of color steel composite plates with the two outer guide plates 51 on another group of color steel composite plates, the butt joint of the two groups of color steel composite plates can be quickly realized.

[0036] In addition, the width value of the inner guide plate 5 is the same as that of the outer guide plate 51, and the width value of the inner guide plate 5 is twice the distance value from the outer side of the side sealing plate 102 to the outer side end of the upper color steel plate 1. The height value of the inner guide plate 5 is adapted to the distance value between the upper and lower groups of bending parts 4, so that a complete inner guide box can be formed between the two side inner guide plates 5 and the upper and lower bending parts 4, and a complete outer guide box can be formed between the two side outer guide plates 51 and the upper and lower bending parts 4. Thus, during the docking process, by inserting the inner guide box into the inner part of the outer guide box, it can play a stable guiding role in the splicing of the two groups of color steel composite plates, and can support the two spliced groups of color steel composite plates, so that the two will not move out of position, and further enable the external connection parts of the two groups of color steel composite plates to always be in an aligned state, facilitating the operator to perform glue sealing and fixation.

[0037] Only some exemplary embodiments of the present invention have been described above by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
