Description
Technical Field
The utility model relates to a field of construction scaffold frame especially indicates a scaffold frame for subway tunnel major structure construction.
Background
The traditional scaffold erection construction of the main structure of the subway tunnel is to start erection construction after the floor concrete reaches the specified strength. The defects of the scaffold erection mode are as follows: firstly, the construction time required to be built is long, and the subsequent construction time is delayed; secondly, the material utilization rate is too low, and the time is consumed for dismantling, finishing and transporting; due to the fact that the construction period of the main subway structure is short, the construction progress of the main subway tunnel structure is influenced by the traditional construction method for building the main subway tunnel structure scaffold.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the problem that exists among the prior art, provide a scaffold frame for subway tunnel major structure construction.
The technical scheme of the utility model is realized like this:
a scaffold for subway tunnel body structure construction, comprising: the scaffold comprises a scaffold body, wherein the scaffold body consists of a plurality of cross rods and vertical rods, a walking device and a jack are arranged at the bottom of the scaffold body, the walking device is arranged at the bottom of the vertical rods deviated to the center, and the top ends of the jacks are propped against the cross rods; the walking device comprises two universal wheels, a fixing plate, a connecting plate and a pin shaft, wherein the fixing plate is symmetrical and welded at the lower end of the vertical rod, the two ends of the fixing plate are connected with one universal wheel through the pin shaft, the universal wheel is further provided with the connecting plate, the pin shaft is installed on the connecting plate, and the other end of the connecting plate is fixed on the other side of the universal wheel through the pin shaft.
Furthermore, the bottom of the vertical rod is also provided with a pin hole, and the pin hole is matched with the pin for use.
And furthermore, the scaffold body is movably connected with the fixed end through a chain block in front.
The utility model has the advantages that: the scaffold can keep moving integrally, so that the labor, material and time consumption in the processes of scaffold dismantling, transporting, re-erecting and the like is reduced, the equipment is simple, the cost is low, the erecting progress of the scaffold of the main structure of the subway tunnel is ensured, and the construction efficiency is effectively improved; the difficult problems of labor and material loss and long construction time in the existing subway tunnel main structure scaffold erection construction are solved.
