Description

Technical Field

[0001] The utility model belongs to the technical field of composite wall panels, and particularly relates to a calcium silicate board composite interior wall panel. Background Art

[0002] With the development of society and the expansion of the construction scale of industrial buildings, various industrial factories, public and civil buildings have emerged continuously. As a green building material, the metal wall system is widely used due to its classic structural characteristics and excellent performance.

[0003] The wall materials of subway stations mainly include metal composite panels, corrugated plates, etc. Due to the limitation of production technology, most of the surfaces of traditional metal wall composite panels are flat, and 0.8mm thick steel plates are mostly used for the plates, and warping is likely to occur on both sides of the plate surface. Most corrugated wall panels are single plates with a thickness between 1.0mm and 1.1mm, and the corrugation size cannot be adjusted. When used on the exterior wall, there are defects such as low strength, inability to effectively insulate, heat-insulate and sound-proof the wall, easy rusting of the exposed nail installation, and easy aging of the surrounding sealant, resulting in leakage. Content of the Utility Model

[0004] In view of the above deficiencies, the utility model provides a calcium silicate board composite interior wall panel, which uses a metal plate with a thickness of 0.2mm to 0.3mm and a calcium silicate board to form an ultra-thin composite interior wall panel. The board has a thin thickness, low manufacturing cost, and is convenient for installation and construction operations of the board in the subway station. Both sides of the metal plate have edges folded towards the calcium silicate board, forming a covering of the calcium silicate board, preventing warping of the composite interior wall panel and improving the structural strength of the composite interior wall panel.

[0005] The utility model is realized through the following technical solutions:

[0006] A calcium silicate board composite interior wall panel is installed vertically on the wall. The composite interior wall panel includes a calcium silicate board and a metal plate adhered to one or both sides of the calcium silicate board. The metal plate is an aluminum plate or a stainless steel plate, and the thickness of the metal plate is 0.2mm to 0.3mm, which is thinner and has a lower cost compared with the plates used in existing subway stations. The metal plate and the calcium silicate board are adhered through a polymer film. Edges folded towards the calcium silicate board are formed on the left and right sides of the metal plate, preventing warping on both sides of the composite interior wall panel.

[0007] Furthermore, a number of evenly distributed weight reduction holes are formed on the calcium silicate board, reducing the overall weight of the calcium silicate board, and thus reducing the weight of the entire composite interior wall panel, saving costs and reducing the installation difficulty of the composite interior wall panel.

[0008] Furthermore, the cross-section of the weight reduction hole is circular, triangular, rectangular or hexagonal.

[0009] Furthermore, the upper and lower sides of the metal plate are formed with edges facing the calcium silicate board, which improves the wrapping degree of the metal plate on the calcium silicate board and improves the structural strength of the composite interior wall panel.

[0010] Furthermore, a central groove is provided on both sides of the calcium silicate board, and the edging includes a side edging plate and an embedded edging plate, the side edging plate is perpendicular to the plate surface of the metal plate and abuts against the side wall of the calcium silicate board, and the embedded edging plate is arranged parallel to the plate surface of the metal plate and extends into the central groove. By bending the embedded edging plate of the edging into the central groove, it helps to prevent the metal plate from being separated from the calcium silicate board, and improves the stability of the connection between the metal plate and the calcium silicate board.

[0011] Furthermore, the width direction of the composite interior wall panel is set as the first direction, the thickness direction is set as the second direction, and the height direction is set as the third direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0012] Furthermore, in the first direction, the length of the embedded wrapping board is smaller than the depth of the central groove, and a first connecting space is formed between the embedded wrapping board and the bottom of the central groove. In the second direction, the width of the central groove is greater than twice the thickness of the embedded wrapping board, and a second connecting space is formed between the two embedded wrapping boards. The first connecting space and the second connecting space are interconnected to form a T-shaped space. The composite interior wall panel also includes an I-shaped connecting piece, which can be plugged into the T-shaped space to achieve connection and fixation between the I-shaped connecting piece and the composite interior wall panel, thereby improving the firmness of the connection between two adjacent composite interior wall panels.

[0013] Furthermore, a guide portion is provided at the bottom of the I-shaped connector, and the width of the guide portion gradually decreases in a direction approaching the first connecting space, so as to facilitate insertion of the I-shaped connector into the first connecting space.

[0014] Furthermore, a plurality of evenly distributed weight-reducing grooves are provided on the calcium silicate board, the weight-reducing grooves are located on both sides of the calcium silicate board, and the weight-reducing grooves on the front side of the calcium silicate board and the weight-reducing grooves on the back side of the calcium silicate board are staggered.

[0034] As Figures 1 to 10 shown, a calcium silicate board composite interior wall panel is installed vertically on the wall. The composite interior wall panel includes a calcium silicate board 1 and metal plates 2 adhered to both sides or one side of the calcium silicate board 1. The metal plates 2 are aluminum plates or stainless steel plates, and the thickness of the metal plates 2 is 0.2 mm to 0.3 mm, which is thinner and has a lower cost compared to the plates used in existing subway stations. The metal plates 2 and the calcium silicate board 1 are adhered through a polymer film. The left and right sides of the metal plates 2 are formed with edges 3 facing the calcium silicate board 1 to prevent the two sides of the composite interior wall panel from warping.

[0035] In one embodiment, when preparing the composite interior wall panel, first, a polymer film is coated on both sides of the calcium silicate board 1, then the metal plates 2 are covered on both sides of the calcium silicate board 1, and the calcium silicate board 1 and the metal plates 2 are heated to melt the polymer film between the calcium silicate board 1 and the metal plates 2, increasing the adhesion between the calcium silicate board 1 and the metal plates 2. A press is used to squeeze the metal plates 2 on both sides of the calcium silicate board 1 so that the metal plates 2 are firmly adhered to both sides of the calcium silicate board 1. Finally, the parts of the metal plates 2 protruding from the calcium silicate board 1 on both sides are bent and pressed against the side walls of the calcium silicate board 1 to form the edges 3 for the calcium silicate board 1, improving the covering effect of the metal plates 2 on the calcium silicate board 1.

[0036] Preferably, a plurality of weight-reducing holes 11 are evenly distributed on the calcium silicate board 1 to reduce the overall weight of the calcium silicate board 1, thereby reducing the weight of the entire composite interior wall board, saving costs, and reducing the installation difficulty of the composite interior wall board.

[0037] In one embodiment, as Figure 3 shown, a plurality of circular weight-reducing holes 11 are provided on the calcium silicate board 1 to achieve weight reduction of the calcium silicate board 1. By providing the weight-reducing holes 11 on the calcium silicate board 1, the weight of the calcium silicate board 1 can be reduced by up to 30%. The materials saved by providing the weight-reducing holes 11 can be reused, effectively saving the cost of preparing the calcium silicate board 1.

[0038] Preferably, the cross-section of the weight-reducing hole 11 is circular, triangular, rectangular or hexagonal.

[0039] Preferably, on the upper and lower sides of the metal plate 2, there are formed edges 3 facing the calcium silicate board 1, which improves the wrapping degree of the metal plate 2 around the calcium silicate board 1 and also improves the structural strength of the composite interior wall board.

[0040] In one embodiment, as Figure 5 and Figure 6 shown, edges 3 for the calcium silicate board 1 are provided on all four sides of the metal plate 2, effectively improving the connection stability between the calcium silicate board 1 and the metal plate 2 and preventing the edges of the calcium silicate board 1 from warping.

[0041] Preferably, center grooves 12 are provided on both sides of the calcium silicate board 1. The edge 3 includes a side edge plate 31 and an embedded edge plate 32. The side edge plate 31 is perpendicular to the plate surface of the metal plate 2 and abuts against the side wall of the calcium silicate board 1, and the embedded edge plate 32 is arranged parallel to the plate surface of the metal plate 2 and extends into the center groove 12. By bending the embedded edge plate 32 of the edge 3 into the center groove 12, it helps to prevent the metal plate 2 from detaching from the calcium silicate board 1 and improves the connection firmness between the metal plate 2 and the calcium silicate board 1.

[0042] In one embodiment, as Figure 7 and Figure 8 shown, the edge 3 of the metal plate 2 extends into the center groove 12 of the calcium silicate board 1, effectively preventing the metal plate 2 from separating from the calcium silicate board 1 due to insufficient adhesion between the metal plate 2 and the calcium silicate board 1. By extending the edge 3 of the metal plate 2 into the center groove 12 of the calcium silicate board 1, the connection tightness between the metal plate 2 and the calcium silicate board 1 is improved.

[0043] Preferably, it is set that the width direction of the composite interior wall board is the first direction, the thickness direction is the second direction, and the height direction is the third direction, and the first direction, the second direction, and the third direction are perpendicular to each other in pairs.

[0044] Preferably, in the first direction, the length of the embedded wrapping board 32 is less than the depth of the central groove 12, and a first connecting space 4 is formed between the embedded wrapping board 32 and the bottom of the central groove 12. In the second direction, the width of the central groove 12 is greater than twice the thickness of the embedded wrapping board 32, and a second connecting space 5 is formed between the two embedded wrapping boards 32. The first connecting space 4 and the second connecting space 5 are interconnected to form a T-shaped space. The composite interior wall panel also includes an I-shaped connecting piece 6, which can be plugged into the T-shaped space to achieve connection and fixation between the I-shaped connecting piece 6 and the composite interior wall panel, thereby improving the firmness of the connection between the two adjacent composite interior wall panels.

[0045] Preferably, a guide portion 61 is provided at the bottom of the I-shaped connector 6 , and the width of the guide portion 61 gradually decreases in a direction approaching the first connecting space 4 , so as to facilitate insertion of the I-shaped connector 6 into the first connecting space 4 .

[0046] In one embodiment, when installing the composite interior wall panels, after the two composite interior wall panels are connected side by side, an I-shaped connector 6 is inserted into the T-shaped space between two adjacent composite interior wall panels, that is, half of the I-shaped connector 6 is inserted into the T-shaped space of the composite interior wall panel on the left, and the other half is inserted into the T-shaped space of the composite interior wall panel on the right, so as to realize the close connection of the two composite interior wall panels.

[0047] Preferably, a plurality of evenly distributed weight-reducing grooves 13 are provided on the calcium silicate board 1, and the weight-reducing grooves 13 are located on both sides of the calcium silicate board 1, and the weight-reducing grooves 13 on the front side of the calcium silicate board 1 and the weight-reducing grooves 13 on the back side of the calcium silicate board 1 are staggered. The weight-reducing grooves 13 are used to reduce the weight of the calcium silicate board 1, which helps to ensure the basic structural strength of the calcium silicate board 1.

[0048] When the calcium silicate board composite interior wall panel is used, a 0.2mm to 0.3mm metal plate 2 is used to composite with the calcium silicate board 1 to form an ultra-thin composite interior wall panel, which has a thin thickness, low manufacturing cost, and is convenient for installation and construction of the panel in the subway station. Both sides of the metal plate 2 have a rim 3 facing the calcium silicate board 1, forming a coating on the calcium silicate board 1, preventing the composite interior wall panel from warping, and improving the structural strength of the composite interior wall panel.
