Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building expansion joint technology, specifically relating to an expansion joint structure for wrought iron railings and curtain walls. Background Technology
[0002] In the construction of a building, expansion joints are inevitably required. However, if these expansion joints are located on the exterior facade, they will disrupt the entire facade's glass, railings, aluminum panels, and other curtain wall systems to meet the building's expansion and contraction requirements. This significantly reduces the building's overall appearance and aesthetics. Therefore, a new type of curtain wall expansion joint structure is needed to achieve the following:
[0003] 1. The curtain wall system needs to have a certain degree of horizontal adjustment capability to adapt to the deformation of the building structure caused by climate change;
[0004] 2. Expansion joints at the railing location must be able to withstand horizontal loads that meet safety standards and must be made of rigid materials to prevent them from falling.
[0005] 3. The expansion joint is located in the middle of the facade curtain wall and runs vertically through it. The client requires that the facade curtain wall look consistent and continuous from the outside to ensure the aesthetic appeal. Utility Model Content
[0006] In view of this, the purpose of this utility model is to provide an expansion joint structure for wrought iron railings and curtain walls to solve the problems existing in the prior art.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] An expansion joint structure for a wrought iron railing curtain wall includes two columns, which are vertically fixed to the building structure and positioned on either side of the expansion joint. A pre-embedded structure is located near either column on the building structure. A safety steel frame is fixedly installed on the surface of the pre-embedded structure. The safety steel frame has an L-shaped cross-section and is vertically positioned between the two columns. A first outer expansion plate and a second outer expansion plate are fixedly installed on opposite sides of the two columns, near the exterior. A first inner expansion plate is fixedly installed on one side of each column, and a second inner expansion plate is fixedly installed on one side of the safety steel frame. The first and second outer expansion plates partially overlap, and the first and second inner expansion plates also partially overlap.
[0009] In a preferred embodiment of the present invention, one side of the first outer telescopic plate is fixedly installed to one of the columns via an adapter, and the other side of the first outer telescopic plate is fixedly installed to another column via a telescopic rubber strip.
[0010] In a preferred embodiment of this utility model, the adapter is two angle aluminum pieces connected by self-tapping screws, and their cross-sections form a Z-shape.
[0011] In a preferred embodiment of this utility model, a cantilever rod is fixedly installed on the side of the first external telescopic plate near the interior, and the cantilever rod and the first external telescopic plate are fixedly installed on the same column.
[0012] In a preferred embodiment of the present invention, the first outer telescopic plate is bent and recessed towards the interior near the middle, and a portion of the second outer telescopic plate overlaps the recess of the first outer telescopic plate. The exterior surfaces of the second outer telescopic plate and the first outer telescopic plate are on the same horizontal plane.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. The curtain wall is horizontally adjustable: the aluminum panels are fixed to the columns on both sides by angle aluminum nails, and are connected or overlapped in the middle by expansion joints. The reinforced safety steel frame is led out from the embedded part on one side by welding and is not connected to the other side. Both have gaps in the horizontal direction to provide deformation allowance, and can also be used for on-site installation and adjustment.
[0015] 2. Aesthetically pleasing appearance: The split curtain wall installation method hides the safety steel frame, gaps that provide deformation allowance, and expansion strips inside, and the exterior is sealed with aluminum panels, avoiding the clutter of multiple materials on the outside and ensuring the consistency and aesthetics of the facade curtain wall.
[0016] 3. The system is applicable to multiple scenarios: It adopts a special internal reinforcement method for the safety steel frame. Under different conditions, such as adding this structure at the location of parapet wall and corridor railing, it can realize the building fall prevention measures and ensure safety. This structure is not required for large curtain walls and inter-floor locations. It can be seen that the presence or absence of wrought iron railings does not affect the appearance of the exterior aluminum panel decorative curtain wall. It can achieve the same facade effect under different building function requirements, improving the applicability of the solution. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0023] Please refer to Figure 1-3 As shown, an embodiment of this application provides a wrought iron railing curtain wall expansion joint structure, including two columns 2, which are fixedly installed vertically to the building body 1. The two columns 2 are located on both sides of the expansion joint 12. A pre-embedded structure 11 is provided near either column 2 of the building body 1. A safety steel frame 6 is fixedly installed on the surface of the pre-embedded structure 11. The cross-section of the safety steel frame 6 is L-shaped and is set vertically between the two columns 2. A first outer expansion plate 4 and a second outer expansion plate 7 are fixedly installed on opposite sides of the two columns 2 near the outside. A first inner expansion plate 9 is fixedly installed on one side of the column 2, and a second inner expansion plate 10 is fixedly installed on one side of the safety steel frame 6. The first outer expansion plate 4 and the second outer expansion plate 7 partially overlap, and the first inner expansion plate 9 and the second inner expansion plate 10 partially overlap.
[0024] Specifically, as shown in the figure, the construction of the entire expansion joint 12 is divided into two independent parts: the wrought iron railing, i.e., the safety steel frame 6, and the surface decoration material.
[0025] The former is made of square tubes welded together, with a width of 330mm and a height of 1420mm. The latter is made of aluminum plates (first outer telescopic plate 4, second outer telescopic plate 7, first inner telescopic plate 9 and second inner telescopic plate 10) and flexible materials such as telescopic rubber strips 8. Before on-site installation, the safety steel frame 6 is assembled separately into an independent grid-like part in the factory or on-site. It can be directly welded to the wall on-site. The aluminum plates and other surface materials are fixed to the columns 2 of the curtain wall on both sides through the adapter 3 (angle aluminum). The deformation is provided by the connection through the telescopic rubber strips 8. The top and bottom are closed by the railing cover and the aluminum plates of the interlayer lines.
[0026] The above structural design gives this telescopic component the following advantages:
[0027] The curtain wall is horizontally adjustable: the aluminum panels are fixed to the two side columns 2 by angle aluminum nails, and are connected or overlapped in the middle by expansion strips 8. The reinforced safety steel frame 6 is led out from the embedded part on one side by welding and is not connected to the other side. Both have gaps in the horizontal direction to provide deformation allowance, and can also be used for on-site installation and adjustment.
[0028] Aesthetically pleasing: The safety steel frame 6, along with the gaps and expansion joints 8 that provide deformation allowance, are concealed inside the split curtain wall installation method. The exterior is sealed with aluminum panels, avoiding the clutter of various materials on the outside and ensuring the consistency and aesthetics of the facade curtain wall.
[0029] The system is applicable to multiple scenarios: It adopts a safety steel frame with special internal treatment for reinforcement. Under different conditions, such as adding this structure at the location of parapet wall and corridor railing, it realizes the building fall prevention measures to ensure safety. This structure is not required for large curtain walls and inter-floor locations. It can be seen that the presence or absence of wrought iron railings does not affect the appearance of the exterior aluminum panel decorative curtain wall. It can achieve the same facade effect under different building function requirements, improving the applicability of the solution.
[0030] In a preferred embodiment of the present invention, one side of the first outer telescopic plate 4 is fixedly installed to a column 2 via an adapter 3, and the other side of the first outer telescopic plate 4 is fixedly installed to another column 2 via a telescopic rubber strip 8.
[0031] In a preferred embodiment of this utility model, the adapter 3 is further composed of two angle aluminum pieces connected by self-tapping screws, and their cross-sections form a Z-shape.
[0032] In a preferred embodiment of this utility model, a cantilever rod 5 is fixedly installed on the side of the first outer telescopic plate 4 near the interior, and the cantilever rod 5 and the first outer telescopic plate 4 are fixedly installed on the same column 2.
[0033] In a preferred embodiment of the present invention, the first outer telescopic plate 4 is further bent and recessed into the interior near the middle, and a portion of the second outer telescopic plate 7 overlaps the recess of the first outer telescopic plate 4, with the outdoor surface of the second outer telescopic plate 7 and the first outer telescopic plate 4 on the same horizontal plane.
[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
