Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] see figure 1 , the embodiment of the present invention comprises two prefabricated wallboards 11, several support rods 7, several support rod connecting seats 9, the wall surfaces of the two prefabricated wallboards 11 are respectively pre-embedded with sleeves, and the two ends of the support rods 7 respectively pass through A supporting rod connecting base 9 is detachably connected with the pre-embedded sleeves on the two prefabricated wall panels 11 .

[0026] The support rod 7 includes a support inner rod 2 and a support outer rod 1 that are nested with each other. The support inner rod 2 is provided with several positioning holes 12 at intervals in the axial direction; the support outer rod 1 is provided with a through groove 13 in the axial direction; The supporting inner rod 2 is inserted in the supporting...

Abstract

The invention relates to a utility tunnel prefabricated panel self-bearing support structure. The structure comprises at least two prefabricated panels which are oppositely arranged in parallel in a vertical mode; at least one horizontal support rod and at least one oblique support rod are arranged between the two prefabricated panels; sleeves are correspondingly pre-embedded into the two prefabricated panels respectively, and the two ends of each support rod are detachably connected with the corresponding sleeves pre-embedded into the two prefabricated panels through support rod connecting bases respectively to form one horizontal support rod or oblique support rod; the length of the support rods can be adjusted. According to the structure, the prefabricated panels are detachably connected through the support rods and the support rod connecting bases, the overall strength of the structure is high, the risk that a single panel collapses and potential safety hazards are excluded, pouring of a base plate is not influenced, and the support rods and the support rod connecting bases can be reused.

Description

technical field [0001] The invention belongs to the technical field of underground structures of fixed buildings, and in particular relates to a self-supporting support structure of prefabricated wallboards in a comprehensive pipe gallery. Background technique [0002] At present, with the continuous development of the economy and the acceleration of urban construction, infrastructure construction is indispensable. As a construction facility built underground in the city to accommodate urban engineering pipelines, the pipe gallery is an important part of urban infrastructure construction. Comprehensive management Corridor, also known as "common ditch" and "common pipeline", is to build a tunnel space underground in the city, integrating various engineering pipelines such as electricity, communication, gas, heating, water supply and drainage, and implementing unified planning. [0003] The side walls of the pipe gallery are usually prefabricated, with a cast-in-place roof abo...
