Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and more specifically to a space frame with ceiling connectors. Background Technology

[0002] With the rapid development of society and the increasingly fast pace of life, the construction industry also demands speed, leading to the emergence of precast steel mesh structures. Currently, there are many types of precast steel mesh structures, but existing ones only include the main body of the building's framework. Components such as ceiling connectors are not precast and must be transported to the site for assembly. This significantly increases the workload during transportation and results in more complex and time-consuming on-site assembly, requiring substantial manpower, thus increasing costs and impacting work efficiency.

[0003] Therefore, how to provide a space frame with ceiling connectors that can greatly reduce manpower, material resources, workload and construction procedures, and effectively shorten the construction period while maintaining work efficiency is one of the technical problems that urgently need to be solved in this field. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A space frame with ceiling connectors includes a space frame body, a profiled steel sheet, and several ceiling connectors. The space frame body is composed of several steel mesh panels fixedly connected by several horizontal bars. Each steel mesh panel is composed of several longitudinal bars and several web bars fixedly connected. Each web bar passes through the profiled steel sheet, and the profiled steel sheet is bolted to the lower part of several web bars.

[0007] Preferably, each of the web reinforcements is fixedly connected to a ceiling connector at the lower end of the portion of the profiled steel sheet through which it passes.

[0008] Preferably, the ceiling connector includes a hanger and a rod; the upper end of the hanger is fixedly connected to the lower end of the bracing rib via a fixing member; the lower end of the hanger is also fixedly connected to the upper end of the rod via the same fixing member.

[0009] Preferably, the portion of the web reinforcement that passes through the profiled steel sheet is provided with external threads; the upper end of the lifting member is fixedly connected to the external thread portion of the web reinforcement through the fixing member.

[0010] Preferably, the upper end portion of the suspension rod is provided with an external thread; the lower end of the suspension member is fixedly connected to the external thread portion of the suspension rod through the fixing member.

[0011] Preferably, the suspension member is provided with a "C" - shaped structure.

[0012] Preferably, the fixing member is a nut.

[0013] Preferably, a number of prestressing tendons are provided in the inner groove of the profiled steel sheet; the prestressing tendons include horizontal prestressing tendons and vertical prestressing tendons; the horizontal prestressing tendons are arranged between the profiled steel sheet and the grid body and are located in the inner groove of the profiled steel sheet; both ends of the vertical prestressing tendons are bolted to the left and right ends of the grid body.

[0014] The technical effect of the above solution is: By arranging the horizontal prestressing tendons and the vertical prestressing tendons in a non - bonded manner, first pouring concrete, then performing prestressing tendon tensioning and bolted fixation, better stability and firmness can be obtained.

[0015] The present utility model has achieved the following technical effects compared with the prior art:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] 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.

[0022] Embodiment

[0023] Refer to Figure 1 As shown, a grid structure with a ceiling connector includes a grid body 1, profiled steel sheets 4, and several ceiling connectors 2. The grid body 1 is fixedly connected and composed of several steel wire mesh sheets through several horizontal bars 12; each steel wire mesh sheet is fixedly connected and composed of several longitudinal bars 11 and several web bars 13; each web bar 13 passes through the profiled steel sheet 4, and the profiled steel sheet 4 is bolted to the lower part of several web bars 13.

[0024] As a preferred or optional mode of this embodiment, refer to Figure 2-3 As shown, a ceiling connector 2 is fixedly connected to the lower end corresponding to the part of each web bar 13 passing through the profiled steel sheet 4. The ceiling connector 2 includes a hanging piece 21 and a hanging rod 22; the upper end of the hanging piece 21 is fixedly connected to the lower end of the web bar 13 through a nut 3; the lower end of the hanging piece 21 is also fixedly connected to the upper end of the hanging rod 22 through a nut 3.

[0025] As a preferred or optional mode of this embodiment, refer to Figure 2-3 As shown, the part of the web bar 13 passing through the profiled steel sheet 4 is provided with an external thread; the upper end of the hanging piece 21 is fixedly connected to the external thread part of the web bar 13 through a nut 3.

[0026] As a preferred or optional mode of this embodiment, refer to Figure 2-3 As shown, the upper end part of the hanging rod 22 is provided with an external thread; the lower end of the hanging piece 21 is fixedly connected to the external thread part of the hanging rod 22 through a nut 3.

[0027] As a preferred or optional mode of this embodiment, refer to Figure 2-3 As shown, the hanging piece 21 is provided with a "C" - shaped structure.

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

[0029] In some other embodiments, as Figure 3 shown, profiled steel sheets 4 are fixedly arranged on both the upper and lower ends of the grid body 1.

[0030] In some other embodiments, as Figure 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.
