Description
Technical field
The utility model is related to building appliance technical field more particularly to a kind of special scaffold hinged roofs of building formwork
Support.
Background technology
China started to apply fastener type steel pipe scaffold at the beginning of the sixties, since this scaffold has assembly and disassembly flexible, removed
Fortune it is convenient, versatile, cheap the features such as, so China apply it is very extensive, usage amount accounts for 60% or more, is to work as
A kind of most scaffold of preceding usage amount.But the greatest weakness of this scaffold is that safety is poor, construction efficiency is low, material
Expect that consumption is big.The beginning of the eighties, China successively introduce the diversified forms scaffolds such as gate-type, bowl fastening type from foreign countries.Bowl fastening type foot hand
Frame is in new type scaffold, and using face is not also wide, is only widely applied in some areas and part engineering.Since the nineties, state
Some interior enterprises develop and develop various new scaffold, such as bolt type scaffold, pulley-clip scaffold, square tower type foot hand
Frame and various types of climbing frames.
But with the improvement of scaffold, mating jacking is not significantly improved but with scaffold.Holder jacking is main
It is the main force transferring structure between holder and template for formwork erection load, there is fixed form, connect the work of formwork system
With.The defect of above-mentioned background technology is primarily present in the following：
1, conventional scaffold jacking screw rod and bracket are welded and fixed, and bracket base is vertical with screw rod, cannot carry out angle tune
Section.When supporting module gradient smaller (being less than 15 °), jacking bracket eccentric compression, formwork keel is easy by pressure is larger
Damage, and bracket is yielding；When supporting module tilt larger (15-45 °) when, for ensure support validity, need to jacking with
Add chock between keel and pad angle, chock is easy to fall off in the construction process, and implementation result is not good enough, or by screw rod and
Lower part scaffolding steel pipe be set as with template vertical direction, while adding fastener and diagonal brace and being connected as one with former frame body, it is both numerous
Trivial and adjustment is difficult.
2, height adjusting nut directly rides on the scaffolding steel pipe of lower part on conventional scaffold jacking screw rod, without other fixations
Measure, screw rod can be deviated by a small margin to be rocked, (such as concreting impact and vibrating spear in superstructure work progress
Vibrate) it is easy to happen template offset, cause construction quality problem.
Utility model content
In view of the present situation of the prior art, it is hinged that the purpose of this utility model is to provide a kind of special scaffolds of building formwork
