CN-224228278-U - Improved Zhang Xianguan truss temporary support frame

Abstract

The utility model discloses an improved Zhang Xianguan truss temporary support frame, and belongs to the technical field of building truss construction. The improved Zhang Xianguan truss temporary support frame comprises a plurality of standard assembling sections fixedly connected after superposition and a cable penetrating section connected to the top of the uppermost standard assembling section, wherein the cable penetrating section is of a square frame support structure, support vertical rods on the side face of the cable penetrating section are rotating vertical columns capable of being turned up and down and used for enabling prestress cables to be horizontally moved out of the cable penetrating section, when the improved Zhang Xianguan truss temporary support frame is particularly used, prestress tensioning is applied to the prestress cables after the assembly of the Zhang Xianguan truss is completed, the truss is stretched to an arch on a string pipe under the action of tensioning force, the bottom of the truss is separated from a support point at the top of the support frame, the rotating vertical columns are turned over, and the Zhang Xianguan truss and the prestress cables are horizontally moved away from the temporary support frame from an opening of the cable penetrating section. The cable section of wearing on interim support frame upper portion need not frequent dismouting, has reached the construction convenience and has practiced thrift construction resources's effect.

Description

Improved Zhang Xianguan truss temporary support frame Technical Field The utility model relates to the technical field of building truss construction, in particular to an improved Zhang Xianguan truss temporary support frame. Background The prestressed string pipe truss is widely applied to industrial buildings and public buildings with super-large span structures after being assembled, when the traditional construction is assembled, the prestressed cable at the lower part of the truss needs to pass through the support frame, after the Zhang Xianguan truss is assembled, the support frame part above the prestressed cable needs to be dismantled, after the truss is horizontally moved away from the support frame, the dismantled support frames are reassembled, and the next string pipe truss is assembled. Disclosure of utility model 1. Technical problem to be solved by the utility model Aiming at the problem of low construction efficiency caused by frequently assembling and disassembling the support frame in the assembly construction of the existing prestress string pipe truss, the utility model provides the improved Zhang Xianguan truss temporary support frame, and the aim of conveniently constructing and saving construction resources is fulfilled by improving the prestress stay rope to penetrate through the stay rope penetrating section at the internode of the support frame, so that the frequent disassembling and assembling of the support frame in the construction process are avoided, the construction efficiency is improved, and the construction resource is saved. 2. Technical proposal In order to achieve the above purpose, the technical scheme provided by the utility model is as follows: The utility model provides an improved generation Zhang Xianguan truss temporary support frame, includes a plurality of standard of fixed connection after the stack and assembles the festival and connect in the cable section of wearing of the top of the standard of the upper strata and assemble the festival, wear cable section for square frame bearing structure, the support montant of its side is the rotation stand that can overturn from top to bottom, supply prestressing force cable to tie up out and wear cable section, when specifically using, zhang Xianguan truss assembled the back that finishes, prestressing force cable applys prestressing force tensioning, it is arched on the string pipe truss under the tensioning force effect, the truss bottom breaks away from support frame top supporting point, rotate the stand upset, zhang Xianguan truss and prestressing force cable are from wearing the opening part translation of cable section and leaving temporary support frame. The cable section of wearing on interim support frame upper portion need not frequent dismouting, has reached the construction convenience and has practiced thrift construction resources's effect. Further technical scheme wears the inboard transverse connection of cable section and has the entablature, and upper and lower entablature is between fixedly connected with additional montant to improve the action load of wearing the cable section, ensure to rotate whole interim support frame after the stand upset and satisfy the structural safety requirement. Further technical scheme, rotate the stand and hinge through the round pin axle and be fixed in and wear the cable section on, realize the upset through the round pin axle, easy operation, it is efficient. Further technical scheme, the round pin axle sets up from top to bottom symmetrically, and the upset of rotation stand is realized to upper round pin axle, and the hasp of rotation stand is realized to lower round pin axle, avoids rotating the stand dislocation. Further technical scheme wears cable section upper portion fixedly connected with cooperation and rotates the stand upset back, will rotate the fixed top couple of stand hook, avoid rotating the stand and leave temporary support frame when the prestressing force cable because of the dead weight turns down. 3. Advantageous effects Compared with the prior art, the technical scheme provided by the utility model has the following beneficial effects: According to the improved Zhang Xianguan truss temporary support frame, through modifying the support frame structure that a guy cable passes through the internode of the support frame, two upright posts of the internode support frame that the guy cable passes through are changed into rotatable upright posts connected through pin shafts, after Zhang Xianguan truss installation is completed, the lower pin shafts of the two upright posts connected through pin shafts are pulled out, the upright posts rotate around the upper pin shafts and are fixed at the top through temporary hooks, a space is reserved for the guy cable to leave the support frame, and after Zhang Xianguan truss and the guy cable completely leave the support frame, the two rotatable upright posts are reset and fixed through the pin shafts, so th
