Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a fixed installation structure for a staggered steel frame of a curtain wall. Background Technology

[0002] In the conventional installation of curtain wall frames, core-sleeve connection is a common method for connecting curtain wall mullions (upper and lower frames). The core mechanism involves inserting a "core" (usually a short tube made of steel or aluminum alloy) into the ends of the upper and lower mullions to achieve mechanical fixation. The core is typically 400mm long, with pre-set grooves or holes inside the lower end of the upper mullion and the upper end of the lower mullion. After the core is inserted, bolts, rivets, or self-tapping screws are used to pass through the corresponding holes in the mullions and core, securing the three components together. However, variations in the finished surfaces of the panels on different floors can cause the curtain wall mullions (upper and lower frames) to be on different finished surfaces, resulting in misalignment. Typically, multiple connectors are used on-site to fix the columns to pre-embedded or post-installed embedded parts. This means that the columns starting from the misaligned position are treated as starting columns again, with the columns having upper round holes and lower elongated holes to form a hanging load-bearing state. This method increases the number of embedded parts and connectors used, as well as the workload of on-site drilling and welding, leading to increased construction costs and extended construction periods. To solve these problems, this utility model designs a novel structure specifically for fixing and installing misaligned steel frames in curtain walls, ensuring the integrity of the structure while reducing construction costs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a fixed installation structure for a staggered steel frame of a curtain wall, which is suitable for situations where the steel frame of the curtain wall is staggered vertically. This structure improves the overall stress on the structure, reduces the number of components, and lowers construction costs.

[0004] This utility model achieves the above-mentioned technical objectives through the following technical means.

[0005] A fixed installation structure for a staggered steel frame of a curtain wall includes an upper inner steel sleeve and a lower inner steel sleeve. A galvanized conversion steel plate is welded to the bottom of the upper inner steel sleeve, and a galvanized conversion steel plate is welded to the top of the lower inner steel sleeve. The upper inner steel sleeve is inserted into the upper galvanized steel column before installation, and the lower inner steel sleeve is inserted into the lower galvanized steel column and fixed by through bolts. The bottom of the upper galvanized steel column and the top of the lower galvanized steel column are welded and fixed to the corresponding galvanized conversion steel plates. The middle galvanized steel column is fixed to the embedded parts of the building structure by galvanized connectors. The top and bottom of the middle galvanized steel column are welded and fixed to the corresponding galvanized conversion steel plates. The galvanized steel beam is fixed to the middle galvanized steel column by steel inserts.

[0006] Furthermore, silicone weather-resistant sealant is injected into the gap between the upper galvanized steel column and the lower galvanized steel column.

[0007] Furthermore, the lengths of both the upper inner steel sleeve and the lower inner steel sleeve are not less than 200mm.

[0008] This utility model has the following beneficial effects: The structure is more integrated and the stress distribution is more reasonable. This utility model can penetrate multiple floors to form a continuous vertical load-bearing component, which can more evenly transfer loads (such as self-weight, wind load, and seismic load) and reduce stress concentration at inter-story nodes.

[0009] This invention reduces the number of components and simplifies construction. It can reduce the number of connections between inter-floor columns and embedded parts, reduce the workload of component processing and installation, and reduce the accumulation of errors caused by multi-node splicing, thus lowering the accuracy control requirements during installation.

[0010] This invention saves materials and reduces costs. It can reduce the use of interlayer connectors and the core itself uses less material, resulting in lower overall costs and reduced labor costs.

[0011] This utility model is specifically designed for situations where the steel frame of a curtain wall is misaligned vertically. It improves the overall stress of the structure, reduces the number of components, minimizes on-site work, lowers construction costs, and ensures the construction period. Attached Figure Description

[0015] like Figures 1 to 3 As shown, the curtain wall misaligned steel frame fixing installation structure of this utility model includes an upper inner steel sleeve core 11, a lower inner steel sleeve core 5, a steel insert core 6, a galvanized conversion steel plate 7, a through bolt 8, a galvanized connector 3, and a pre-embedded part 2.

[0016] like Figures 1 to 3 As shown, the lower galvanized steel column 1 and the lower inner steel sleeve core 5 at the misaligned position of the curtain wall steel frame are pre-processed with through bolt installation holes before actual construction.

[0017] like Figures 1 to 3 As shown, a galvanized conversion steel plate 7 is welded to the bottom of the upper inner steel sleeve core 11, and a galvanized conversion steel plate 7 is welded to the top of the lower inner steel sleeve core 5. The upper inner steel sleeve core 11 with the welded galvanized conversion steel plate 7 is inserted into the upper galvanized steel column 10 before installation. The lower inner steel sleeve core 5 with the welded galvanized conversion steel plate 7 is inserted into the lower galvanized steel column 1 and fixed by through bolts 8. The bottom of the upper galvanized steel column 10 is welded to the galvanized conversion steel plate 7 on the upper inner steel sleeve core 11, and the top of the lower galvanized steel column 1 is welded to the galvanized conversion steel plate 7 on the lower inner steel sleeve core 5.

[0018] like Figures 1 to 3 As shown, at the misaligned position of the curtain wall steel frame, the upper and lower parts of the central galvanized steel column 12 are fixed to the embedded parts 2 of the building structure through galvanized connectors 3; the top and bottom of the central galvanized steel column 12 are welded and fixed to the galvanized conversion steel plate 7.

[0019] like Figures 1 to 3 As shown, the galvanized steel beam 4 is fixed to the middle galvanized steel column 12 by the steel insert 6. The galvanized steel beam 4, the middle galvanized steel column 12, the upper galvanized steel column 10, and the lower galvanized steel column 1 make the entire curtain wall frame a whole.

[0020] like Figures 1 to 3As shown, silicone weather-resistant sealant 9 is injected into the gap between the upper galvanized steel column 10 and the lower galvanized steel column 1 to achieve sealing and waterproofing on the one hand, and to adapt to expansion and contraction deformation on the other hand; the lengths of the upper inner steel sleeve core 11 and the lower inner steel sleeve core 5 are both not less than 200mm.
