Technical Field

[0001] The utility model relates to the technical field of stone curtain walls, in particular to a deformation-proof stone curtain wall structure. Background Technique

[0002] As a modern building exterior wall decoration technology, the dry-hanging stone curtain wall is widely used in high-rise buildings, commercial complexes, public buildings and other fields due to its advantages such as beauty, durability, and convenient construction. However, due to the external forces such as temperature changes, wind loads, and earthquakes on the building structure, the stone curtain wall will deform, and the design and construction of deformation joints have become one of the key technologies in the dry-hanging stone curtain wall project.

[0003] However, in practical applications, the structural design at the deformation joint still has disadvantages such as poor aesthetics, insufficient sealing performance, and complex installation. How to improve the ornamental value of the deformation joint part while ensuring the function of the deformation joint itself has become a technology亟待解决的一项技术. Content of the Utility Model

[0004] The utility model aims to solve the above problems and provides a deformation-proof stone curtain wall structure, and the technical scheme adopted is as follows: A deformation-proof stone curtain wall structure includes a post-embedded plate, vertical keels, angle steels, a stone curtain wall and a deformation-proof mechanism. The post-embedded plate is fixed on the base wall through embedded bolts, and a connecting piece is welded on the side of the post-embedded plate away from the base wall. The connecting pieces are arranged in pairs. The vertical keels are arranged longitudinally, and the vertical keels are fixedly connected between the paired connecting pieces through keel anchor bolts. The side of the vertical keel away from the base wall is fixedly connected with the angle steels. The angle steels are arranged in a horizontal direction parallel to the base wall, and back bolts are fixedly connected to the angle steels. The stone curtain wall is fixedly connected to the angle steels through the back bolts; the deformation-proof mechanism is arranged in the gap between adjacent stone curtain walls.

The pre-embedded connecting plates are arranged in pairs and symmetrically about the central axis of the gap. The outer aluminum plate is a "convex"-shaped open bent plate. The middle part of the outer aluminum plate protrudes away from the base wall and is clamped between adjacent stone curtain walls. The two ends of the outer aluminum plate respectively overlap and are fixedly connected with the second bent parts on both sides of the gap. A polyurethane foam layer is filled in the cavity formed by the base wall, the second bent parts on both sides and the outer aluminum plate.

[0006] Preferably, the second bent portion is fixedly connected to the outer aluminum plate by aluminum plate connecting bolts.

[0007] Based on the above scheme, elongated holes are provided on the first bending part and the second bending part respectively, and the pre-embedded bolts and aluminum plate connecting bolts pass through the elongated holes of the first bending part and the second bending part respectively.

[0008] Preferably, pre-pressed sealing strips are pasted between the two sides of the middle part of the outer aluminum plate and the two sides of the stone curtain wall, and the outer end of the pre-pressed sealing strip is flush with the outer surface of the outer aluminum plate.

[0010] Preferably, the color of the outer surface of the middle part of the outer aluminum plate is the same as the color of the stone curtain wall.

[0011] Preferably, the angle steel is welded to the vertical keel on the side closest to the base wall.

[0012] The beneficial effects of this utility model are as follows: The anti-deformation mechanism is firmly and reliably installed on the base wall via pre-embedded connecting plates, preventing loosening or deformation. T-shaped aluminum cladding panels are installed between adjacent stone curtain walls to flexibly accommodate installation needs with gaps of varying widths. The outer surface of the aluminum cladding panels matches the outer surface of the stone curtain wall, enhancing the aesthetics of the curtain wall structure. A polyurethane foam layer is filled between the pre-embedded connecting plates and the aluminum cladding panels, and pre-compression sealing strips and sealant are installed at the connection points to improve the waterproofing and thermal insulation of the curtain wall structure.

[0017] like Figures 1 to 3As shown in the figure, a deformation-proof stone curtain wall structure is characterized by comprising a post-embedded plate 21, vertical keels 32, angle steels 41, a stone curtain wall 5 and a deformation-proof mechanism. The post-embedded plate 21 is fixed on a base wall 1 through embedded bolts 22. A connecting piece 31 is welded to the side of the post-embedded plate 21 away from the base wall 1. The connecting pieces 31 are arranged in pairs. The vertical keels 32 are arranged longitudinally, and the vertical keels 32 are fixedly connected between the paired connecting pieces 31 through keel anchor bolts 33. The side of the vertical keels 32 away from the base wall 1 is fixedly connected to the angle steels 41. The angle steels 41 are arranged in a horizontal direction parallel to the base wall 1.

[0018] The deformation-proof mechanism is arranged in the gap between adjacent stone curtain walls 5. The deformation-proof mechanism comprises a pre-embedded connecting plate 61 and an outer aluminum plate 82. The pre-embedded connecting plate 61 is an L-shaped bent plate, comprising a first bent part and a second bent part fixedly connected. The first bent part is fixedly pressed between the base wall 1 and the thermal insulation layer 23 through a pre-embedded bolt 62. The second bent part extends towards the side of the stone curtain wall 5. The pre-embedded connecting plates 61 are arranged in pairs and symmetrically about the central axis of the gap. The outer aluminum plate 82 is a "convex"-shaped open bent plate. The middle part of the outer aluminum plate 82 bulges away from the base wall 1 and is clamped between adjacent stone curtain walls 5. Therefore, the middle part of the outer aluminum plate 82 is exposed outside between adjacent stone curtain walls 5. The color of the outer surface of the middle part of the outer aluminum plate 82 is set to be the same as or the pattern is similar to that of the stone curtain wall 5 to improve the aesthetic degree of the curtain wall structure.

[0019] Both ends of the outer aluminum plate 82 respectively overlap and are fixedly connected to the second bent parts on both sides of the gap. A polyurethane foam layer 7 is filled in the cavity formed by the base wall 1, the second bent parts on both sides and the outer aluminum plate 82 to improve the heat insulation and waterproof performance at the gap between adjacent stone curtain walls 5.

[0020] An isolation cushion block 81 is arranged at the overlapping part of the second bent part and the outer aluminum plate 82. The isolation cushion block 81 is made of a non-metallic material, and the isolation cushion block 81 is arranged between the second bent part and the outer aluminum plate 82. By arranging the isolation cushion block 81, the pre-embedded connecting piece 61 and the outer aluminum plate 82 are prevented from directly contacting, and the phenomenon of bimetallic corrosion is prevented.

[0021] The second bent part and the outer aluminum plate 82 are fixedly connected through an aluminum plate connecting bolt 83. Long round holes are respectively arranged on the first bent part and the second bent part. The pre-embedded bolt 62 and the aluminum plate connecting bolt 83 respectively penetrate through the long round holes of the first bent part and the long round holes of the second bent part. By arranging the long round holes, the installation and connection positions of the anchor bolts and the bolts can be adjusted according to the actual installation scenario and requirements, so as to improve the structural adaptability.

[0022] Pre-pressed sealing strips 84 are respectively pasted between the two sides of the middle portion of the outer aluminum cladding plate 82 and the sides of the stone curtain wall 5. The outer ends of the pre-pressed sealing strips 84 are flush with the outer surface of the outer aluminum cladding plate 82, and the pre-pressed sealing strips 84 are used to seal and waterproof the installation gaps. The outer surface of the stone curtain wall 5 protrudes from the outer surface of the middle portion of the outer aluminum cladding plate 82, and sealant 85 is applied between the outer aluminum cladding plate 82 and the sides of the stone curtain wall 5.
