Description

Technical Field

[0001] The utility model belongs to the technical field of super high-rise steel structures and prefabricated installation technologies, and particularly relates to a curtain wall turning opening forming structure. Background Art

[0002] As the preferred solution for the exterior decoration of modern super high-rise buildings, the installation of curtain walls usually depends on the embedded parts of the main structure for hanging connection. To ensure that the curtain wall embedded part steel bars meet the anchoring requirements, the traditional method is to thicken the floor slabs around the structure periphery to form a curtain wall turning opening. However, in a pure concrete structure, the construction of the curtain wall turning opening requires operations such as formwork support. The construction process is not only cumbersome, but also there are certain safety hazards due to the edge operation, which is not conducive to the smooth progress of on-site construction. Content of the Utility Model

[0003] Aiming at the problems in the above-mentioned prior art, the utility model provides a curtain wall turning opening forming structure, and specifically discloses the following technical solutions:

[0004] A curtain wall turning opening forming structure includes a plurality of cantilever steel beams welded to the outer side of the web of the floor I-beam. The plurality of cantilever steel beams are arranged at intervals. One end top of the plurality of cantilever steel beams away from the floor I-beam is connected by an angle steel to form a support frame, and a turning opening forming die is arranged at the top end of the support frame.

[0005] Further, the turning opening forming die includes a bottom template, an inner template and an outer template. The bottom template is arranged on the support frame. The inner template is fixedly connected to the inner side of the top end of the bottom template. The outer template is fixedly connected to the outer side of the top end of the bottom template. The inner template is arranged close to the outer end of the flange of the floor I-beam and its top surface is flush with the top surface of the floor I-beam. The top surface of the outer template is higher than the top surface of the inner template.

[0006] Further, the bottom template, the inner template, the outer template and the two end templates are all made of galvanized sheets.

[0007] Further, a backing plate is also welded to the top end of the cantilever steel beam, and the upper surface of the backing plate is flush with the top surface of the angle steel.

[0008] Further, the angle steel is welded to each of the plurality of cantilever steel beams.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] By welding several cantilever I-beams on the outer side of the web of the floor I-beam and connecting several cantilever I-beams with angle steel to form a support frame, the support for the turnover opening forming die can be realized, which can reduce the on-site formwork support work, improve the construction efficiency, avoid the edge operation of operators, and improve the construction safety.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0016] Refer to Figures 1-3 , a curtain wall turnover opening forming structure, including several cantilever I-beams 2 welded on the outer side of the web of the floor I-beam 1. The several cantilever I-beams 2 are arranged at intervals. The tops of the several cantilever I-beams 2 far from the floor I-beam 1 are connected by angle steel 3 to form a support frame, thereby forming a stable support structure. A turnover opening forming die is arranged at the top end of the support frame.

[0017] In this embodiment, the welding position of the cantilever I-beam 2 can be determined according to the preset elevation on the lower side of the curtain wall turnover opening. By adjusting the welding height of the cantilever I-beam 2, the thickness of the turnover opening can be adjusted.

[0018] In this embodiment, the turned-up edge forming die includes a bottom template 4, an inner template 5, and an outer template 6. The bottom template 4 is arranged on the support frame. The inner template 5 is fixedly connected to the inner side of the top end of the bottom template 4. The outer template 6 is fixedly connected to the outer side of the top end of the bottom template 4. The inner template 5 is arranged closely against the outer end of the flange of the floor I-beam 1 and its top surface is flush with the top surface of the floor I-beam 1. The top surface of the outer template 6 is higher than the top surface of the inner template 5, so as to facilitate the integral casting of the truss floor slab 8 and the turned-up edge 9.

[0019] In this embodiment, the bottom template 4, the inner template 5, and the outer template 6 are all made of galvanized sheets.

[0020] In this embodiment, a backing plate 7 is also welded to the top end of the cantilever I-beam 2, and the upper surface of the backing plate 7 is flush with the top surface of the angle steel 3 to ensure that the bottom template 4 remains in a horizontal state.

[0021] In this embodiment, the angle steel 3 and several of the cantilever I-beams 2 are all welded.

[0022] In practical applications, first, determine the position and size of the turned-up edge according to the requirements of the building design. Then, prefabricate the cantilever I-beams 2, angle steels 3, and each template constituting the turned-up edge forming die in the factory. During on-site installation, first weld the cantilever I-beams 2 to the building main structure (floor I-beam 1), and adjust their height and length to adapt to different turned-up edge requirements. Then, use the angle steels 3 to connect the cantilever I-beams 2 to form a stable support frame. Then, install the turned-up edge forming die to ensure that it can effectively block the concrete. Finally, place the steel bar truss on the upper surface of the building main structure and inside the turned-up edge forming die and pour the concrete, so that the steel bar truss floor slab and the turned-up edge are formed together.

[0023] This setting form not only simplifies the construction process, but also greatly improves the construction efficiency and safety. Since most of the work can be completed in the factory and only assembly is required on-site, the on-site formwork support and edge operations are effectively reduced, and the construction risk is lowered. At the same time, this method also has good adaptability and can meet the requirements of different buildings by adjusting the sizes of each component.

[0024] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and decorations made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
