Description
Technical field
The utility model belongs to scaffold fixation means field more particularly to a kind of overhanging I-steel security hardening structure.
Background technique
Construction scaffold security protection be building construction site safety protection important component, usual multilayer or
The scaffold protection of small sized multiple story building object, which is set up, mostly uses console mode protective scaffold；High-rise mostly uses segmentation to overhang
Protective scaffold or whole promotion protective scaffold；It requires to be told somebody what one's real intentions are according to the design of respective Project Construction Organization or scheme, take
If, examination, use, supervision etc..Its builder's jack on the middle and senior level used, which is substantially to be overhang with I-steel from beam slab edge, to be stretched
It is built into the pedestal of scaffold out.There is firm connection structure to overhang I-steel and beam slab, mainly have at present following
Two kinds of ways:
1, reinforcing built-in fitting of U-shaped hot calendering circle 16 round steel of HPB235 Φ of pre-buried clod wash as I-steel.In overhanging type
The end of steel should be designed to wirerope or reinforcing pull rod and upper one layer of major structure of construction oblique pull off-load, and on oblique pull wirerope
The pre-buried hanging ring bar diameter of fixing end answers >=Φ 20mm, the same U type hot calendering circle HPB235 round steel using clod wash.It is building
Build on building site it is most of at present using wirerope come oblique pull off-load, diameter >=Φ 14mm of wirerope specifically will be by calculating really
It is fixed.Present common practice is: generally welding one section of bar dowel or short not less than the position of 100mm apart from fashioned iron overhanging end
Steel pipe, length are about 200mm, general diameter of phi 20mm- Φ 30mm.
2, using JGJ130-2011 " construction fastener type steel pipe scaffold technical specification of security " and Zhong Jian joint-stock company
The U-shaped ring of the pre-buried TBE (threaded both ends) required in 2014 editions " construction site safety protection standard atlas ".
Above-mentioned construction method has the disadvantage that
It is more using material, be not achieved economical environment-protective green construction original intention, the later period remove with gas cutting Floor water plane with
Upper bit is cut off, and causes to waste, can't be used in turn, operator's workload is big, the activity duration is long, construction worker not
Fire risk can also carefully occur, security risk is big.
Chinese patent CN201521113472.4 discloses a kind of overhanging I-steel security hardening structure, including from beam slab side
The I-steel stretched out along overhanging；The front of I-steel is equipped with prelocalization hoop, and the tail portion of I-steel passes through rear positioning component and this
Floor plate or beam slab connection；The front end of I-steel is connect by oblique pull wirerope with upper floor edges of boards edge.The patent solves well
It has determined above-mentioned problem, but has been to have shortcoming in safety precaution, had the following problems: even if 1, I-steel is to anchor
It can not fully ensure that it cannot be moved axially under the coupling mechanism force of bolt and upper casting die；2, the installation positioning of I-steel needs artificial
It borrows other gages and carries out artificial measurement positioning, increase the amount of labour of worker, reduce labor efficiency；3, jackscrew is arranged in lower end,
It is inconvenient, it in work progress, if desired adjusts, worker needs body leaning out safety zone, increases construction personnel's safety
Hidden danger；4, lack limiting device on I-steel, be unable to further progress second protection, can just give birth to security risk；5, spiral shell is anchored
Bolt and anchor plate are using the form welded, though having achieved the effect that recycle, are welding and separating anchor bolt and anchor
Gu when steel plate, all producing destructiveness to workpiece, recovering effect is not apparent.
Utility model content
