Description

Technical Field

[0001] The utility model relates to the technical field of stone curtain wall paving, in particular to a hidden external wall deformation joint structure used for the stone curtain wall of a building. Background Art

[0002] For large and medium-sized buildings, external wall deformation joints are inevitable building structures used to cope with the deformation of the external wall structure caused by external factors; however, since external wall deformation joints will produce an obvious gap, they will have a greater negative impact on the building's facade image.

[0003] In the existing exterior wall projects that are mainly based on stone curtain walls, the stone panels have to open sufficiently wide gaps at the locations of the exterior wall deformation joints to meet the deformation requirements, and the gaps need to be sealed to form a complete set of exterior wall deformation joint structures. However, such a structure can easily destroy the integrity and aesthetics of the stone curtain wall, thus forming a flaw in the exterior image of the building; therefore, how to maximize the integrity and aesthetics of the stone curtain wall while meeting the technical requirements for the deformation of the exterior wall structure is the main problem that needs to be solved in the current exterior wall projects. Summary of the invention

[0004] The utility model aims to solve the defects of the prior art and provide a hidden external wall deformation joint structure for the stone curtain wall of a building.

[0005] In order to achieve the above purpose, the utility model can adopt the following technical solutions:

[0015] like Figure 1 , 2 As shown, the hidden external wall deformation joint structure for the stone curtain wall of a building described in the utility model comprises a deformation joint 2 arranged on the external wall 1 of the building, and a plurality of stone panels 3 laid on the outside of the external wall 1 of the building. Among them, the deformation joint 2 is a gap reserved at a suitable position according to the deformation of the external wall structure of the building under actual construction, and its width is calculated according to the structure; and the stone panels 3 are arranged continuously in the horizontal and vertical directions, and maintain a certain gap between them and the external wall 1 of the building during paving. The thickness of the stone panels 3 is generally greater than or equal to 25mm, and a splicing seam 4 is reserved between two adjacent stone panels 3, and the width of the splicing seam 4 is greater than or equal to 8mm and is smaller than the width of the deformation joint 2.

[0016] The deformation joint 2 is filled with thermal insulation rock wool 5, which has certain flexibility. It can not only form effective thermal insulation and sealing, but also can deform along with the building outer wall 1 when it is deformed by external factors.

[0017] A first connecting plate 6 is attached to the building outer wall 1, which spans the deformation joint 2. The first connecting plate 6 has a first fold line segment 7 facing the deformation joint 2. The first fold line segment 7 is in a W-shaped structure, which can provide a certain deformation capacity. In addition, a second connecting plate 8 is also attached to the building outer wall 1. The upper edge of the second connecting plate 8 is folded outward to form a horizontal connecting section 9. The outer edge of the horizontal connecting section 9 is folded upward to form a vertical connecting section 10 for connecting with the stone panel 3. The vertical connecting section 10 has a second fold line segment 11 facing the joint 4. The second fold line segment 11 is in a V-shaped structure, which can also provide a certain deformation capacity. Specifically, the second connecting plate 8, the horizontal connecting section 9 and the vertical connecting section 10 are integrally formed. Like the first connecting plate 6, they can all be made of galvanized steel plates with a thickness greater than or equal to 0.5 mm. In actual installation, the first connecting plate 6 and the second connecting plate 8 can be anchored to the stone panel 3 by plastic expansion anchor bolts 12 with a diameter greater than or equal to 8 mm.

[0018] In addition, a first flexible sealing strip 13 is also provided in the joint 4, and a second flexible sealing strip 14 is also provided between the vertical connection section 10 and the stone panel 3, wherein the second flexible sealing strip 14 is divided into two groups, and is respectively located at the upper and lower sides of the second fold line section 11. Specifically, the first flexible sealing strip 13 and the second flexible sealing strip 14 are both foam plastic rods, and the outer side of the first flexible sealing strip 13 and the sides of the two second flexible sealing strips 14 close to the second fold line section 11 are filled with silicone sealant 15, and the first flexible sealing strip 13 and the second flexible sealing strip 14 are bonded by the silicone sealant 15, so that an elastic structure is formed at the joint 4 of the adjacent stone panels 3 and between the vertical connection section 10 and the stone panel 3, and at the same time, the silicone sealant 15 filled on the outer side of the first flexible sealing strip 13 can also make the outer side of the joint 4 smoother, thereby improving the aesthetics of the outer side of the stone panel 3.

[0019] During the specific construction:

[0020] The first step is to reserve a deformation joint 2 at a suitable position of the building outer wall 1 according to the specific structure of the building (the width of the deformation joint 2 is calculated according to the specific structure of the building), then fill the deformation joint 2 with thermal insulation rock wool 5, and fix the first connecting plate 6 to the building outer wall 1 on both sides of the deformation joint 2 by plastic expansion anchor bolts 12, so that the first broken line segment 7 of the W-shaped structure on the first connecting plate 6 faces the deformation joint 2;

[0021] The second step is to perform a paving project of a stone panel 3 on the outdoor side of the building exterior wall 1, and determine the specific position of the joint 4 according to the facade design requirements, so as to hide the deformation joint 2 inside the stone panel 3;

[0022] The third step is to fix the second connecting plate 8 to the building outer wall 1 by means of the plastic expansion anchor bolts 12, and to make the second fold line segment 11 on the vertical connecting segment 10 face the joint seam 4;

[0023] Step 4: Place a second flexible sealing strip 14 in the gap between the vertical connection section 10 and the stone panel 3, and fix the second flexible sealing strip 14 with a silicone sealant 15; the second flexible sealing strip 14 is divided into two groups, which are respectively located on both sides of the second fold line section 11, so that the stone panel 3 and the vertical connection section 10 are elastically connected by the second flexible sealing strip 14;

[0024] The fifth step is to place a first flexible sealing strip 13 in the joint seam 4, and fill the joint seam 4 outside the first flexible sealing strip 13 with silicone sealant 15 to complete the sealing of the joint seam 4, and at the same time connect the two adjacent stone panels 3 together, so as to form a complete hidden exterior wall deformation joint structure together with the deformation joint 2 of the exterior wall 1 of the building, which can not only hide the deformation joint 2 set on the exterior wall 1 of the building well, but also fully realize the appearance design requirements of stone curtain wall buildings. On the premise of meeting the technical requirements of exterior wall deformation, the integrity and aesthetics of the stone curtain wall are guaranteed to the greatest extent, and the balance between technology and appearance is achieved, with strong economy and ease of operation.
