DETAILED DESCRIPTION

[0021] With reference to the drawings and the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative effort belong to the scope of the present application.

[0022] Embodiment

[0023] Referring to Figure 1 The grid frame with the ceiling connecting piece shown in the figure comprises a grid frame body 1, profiled steel plates 4 and a plurality of ceiling connecting pieces 2. The grid frame body 1 is composed of a plurality of steel mesh sheets fixedly connected by a plurality of horizontal reinforcement bars 12. Each steel mesh sheet is composed of a plurality of longitudinal reinforcement bars 11 and a plurality of web reinforcement bars 13 fixedly connected. Each web reinforcement bar 13 passes through the profiled steel plate 4, and the profiled steel plate 4 is bolted to the lower part of the plurality of web reinforcement bars 13.

[0024] As a preferred or optional mode of the present embodiment, referring to Figures 2-3 The lower end of the part of each web reinforcement bar 13 passing through the profiled steel plate 4 is fixedly connected with a ceiling connecting piece 2. The ceiling connecting piece 2 comprises a hanging piece 21 and a hanging rod 22. The upper end of the hanging piece 21 is fixedly connected with the lower end of the web reinforcement bar 13 through a nut 3. The lower end of the hanging piece 21 is also fixedly connected with the upper end of the hanging rod 22 through a nut 3.

[0025] As a preferred or optional mode of the present embodiment, referring to Figures 2-3 The part of the web reinforcement bar 13 passing through the profiled steel plate 4 is provided with external threads. The upper end of the hanging piece 21 is fixedly connected with the external thread part of the web reinforcement bar 13 through a nut 3.

[0026] As a preferred or optional mode of the present embodiment, referring to Figures 2-3 The upper end part of the hanging rod 22 is provided with external threads. The lower end of the hanging piece 21 is fixedly connected with the external thread part of the hanging rod 22 through a nut 3.

[0027] As a preferred or optional mode of the present embodiment, referring to Figures 2-3 The hanging piece 21 is provided with a "D" shaped structure.

[0028] In some embodiments, the specific structure of the hanging piece 21 can be adjusted according to actual needs.

[0029] In some other embodiments, as shown in Figure 3 The profiled steel plates 4 are fixedly arranged at the upper and lower ends of the grid frame body 1.

[0030] In some other embodiments, as shown in Figures 1-3In this structure, several prestressing tendons are arranged within the internal groove of the profiled steel sheet 4. These prestressing tendons include transverse prestressing tendons 5 and vertical prestressing tendons 6. The transverse prestressing tendons 5 are positioned between the profiled steel sheet 4 and the space frame body 1, and are located within the internal groove of the profiled steel sheet 4. The vertical prestressing tendons 6 are bolted to the left and right ends of the space frame body 1. By employing a non-adhesive method to install the transverse and vertical prestressing tendons, concrete is poured first, followed by prestressing tendon tensioning and bolting fixation, better stability and robustness are achieved.

[0031] This invention involves threading the lower end of the web reinforcement of the space frame and then directly fixing the ceiling connector to the prefabricated space frame using nuts. This eliminates the need for separate installation of the ceiling connector during installation and avoids the step of installing the ceiling connector after the wall panels have been cast. This effectively reduces on-site assembly procedures, simplifies installation, significantly shortens the construction period, and effectively improves work efficiency, saving costs. It also effectively reduces the workload during transportation, further saving costs and making it suitable for market promotion.

[0032] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
