In the prior art, as depicted in figs. 1 and 2, the steel tube fastener formula support for shuttering support overweight plate of large span is generallyd use, this
Kind support for shuttering includes cross bar, upright bar and the fastener for connecting cross bar and upright bar, upper and lower two upright bars, and the top of upright bar is laid with glued
Plate.
This support for shuttering structure is simple, and manufacturing cost is not high, but the duration is longer, and stability is bad, poor safety performance.
Utility model content
Be attached for support for shuttering in practice using fastener type, long in time limit, stability is bad, poor safety performance this
One problem, the purpose of this utility model is that proposing a kind of overweight plate load-bearing support for shuttering of large span, concrete scheme is as follows：
A kind of large span overweight plate load-bearing support for shuttering, including four mobile jibs, the mobile jib are connected up and down by more upright bars
It connects, the junction of upper and lower two upright bars is provided with secondary bar, the top of four mobile jibs between the adjacent mobile jib
Portion is equipped with support plate, and upper and lower two upright bars are threadedly coupled, at least one described secondary bar includes hinged two of one end rotation
A cross bar, the free end of the cross bar are fixedly connected with the bottom of the upright bar, solid by locking member between two cross bars
It is fixed.
Through the above technical solutions, upper and lower two upright bars are threadedly coupled, structure is simple, and connection is reliable, is convenient to mount and dismount, formwork
The stable structure of frame.Two cross bars are hinged and the bottom of upright bar is arranged in, and when installation, the hinged end of two cross bars is struck directly to drive
Minor rotation is done in two upright bars of dynamic connection, so that the threaded connection of upper and lower two upright bars is closer, the structure of support for shuttering is more steady
It is fixed.When disassembly, the hinged end of two cross bars is clenched into folding, two cross bars rotate and synchronize two upright bar opposite directions of driving do it is small
Rotation, so that the threaded connection place of upper and lower two upright bars loosens, screws upright bar conveniently to dismantle.This support for shuttering it is convenient for disassembly and assembly,
Structural strength is big, and stability is good, and security performance is good.
Further, the bottom outer-edge of the upright bar is provided with clamping block, and the level cross-sectionn of the clamping block is in polygon
Shape setting, the free end of the cross bar offer clamping groove compatible with the clamping block, and the free end of the cross bar is arranged
