Description
Technical field
Of the invention and a kind of construction method of outer builder's jack I-steel.
Background technique
Builder's jack is as technical equipment indispensable in high-building construction and construction means, in builder's jack
It is generallyd use in construction and sets up builder's jack in such a way that code requirement computational length fashioned iron and anchoring piece are fixed.Due to fashioned iron
The length of overhanging determines building interior anchorage length, so that overhang layer fashioned iron needed length multiplicity, virtually increases compared with multiplexing
Work amount and cost, cumbersome and fashioned iron, which is anchored in floor, to bring inconvenience to construction in building, when in addition fashioned iron is removed due to
Interior construction spacing limitation needs tower crane to cooperate to pull out outside building, and secure context increases more risk and uncertainty.
Summary of the invention
The present invention is directed to overcome the deficiencies of existing technologies, a kind of construction method of outer builder's jack I-steel is provided, is protected
Construction safety is demonstrate,proved, flexible operation is easy, accelerates construction progress, facilitates turnover, save the cost.
In order to solve the above-mentioned technical problem, the present invention is implemented as follows:
A kind of construction method of outer builder's jack I-steel, it is characterised in that it includes the following steps:
Step 1: production overhanging I-steel telescopic mounting, telescopic mounting by rectangular steel pipe inner sleeve I-steel processing and fabricating and
At wherein rectangular steel pipe is net long, tall and big in I-steel length, high 10mm, and the wall thickness of rectangular steel pipe cannot be less than I-steel abdomen
Plate thickness；
Step 2: then the pre-buried anchor bolt before overhang layer structural slab concreting will overhang I-steel telescopic mounting
Wooden box is placed with cast-in fixing bolt fixed structure plate face, and in the concrete walls position of lap-joint, being wrapped in overhanging I-steel outside can stretch
On the outside of compression apparatus rectangular steel pipe, and there are the gaps 30mm；
Step 3: the outer of I-steel in overhanging I-steel telescopic mounting is adjusted by arrangement and method for construction and chooses length, choosing length outside must not
Greater than the 2/3 of I-steel overall length, and the group in such a way that the limit hole in rectangular steel pipe long side and I-steel web is inserted into lock
At limiting device, it is ensured that I-steel is difficult to slide, is then overhang on I-steel outside and sets up external scaffolding；
Step 4: after outer builder's jack is removed, first limiting device is opened and is contracted to I-steel in rectangular steel pipe, then
Pre-buried fixing bolt is dismantled, it can be by recycling and reusing one by one in building；
Step 5: inspecting for acceptance, and the construction of setting and connection of rod piece etc. should meet the requirement of specification and scheme；Such as overhang foot hand
Frame scaffolding height is more than limit value, is proved by the stringent organizes expert of related request.
The beneficial effects of the present invention are: being hanged for the fixed suitable profile complex building that is difficult of market overhanging steel I-beam length
The challenges such as layer I-steel arrangement, calculating, selection are chosen, can more be had using overhanging I-steel telescopic mounting and construction method
The solution of effect.Cantilever Beams flexible arrangement under different operating conditions is realized by the method, and overhanging I-steel can be stretched after outrigger dismounting
Compression apparatus can recycle after shortening from building interior, substantially reduce overhanging I-steel and remove security risk.The construction method is guaranteeing
Construction safety, flexible operation is easy, accelerates construction progress, facilitates turnover, save the cost.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the side view that I-steel telescopic mounting is overhang in Fig. 1.
Specific embodiment
As shown in Figure 1, 2: a kind of construction method of outer builder's jack I-steel includes the following steps:
Step 1: production overhanging I-steel telescopic mounting, telescopic mounting is by 2 inner sleeve I-steel of rectangular steel pipe, 3 processing and fabricating
It forms, wherein net long, the tall and big 10mm long, high in I-steel of rectangular steel pipe, and the wall thickness of rectangular steel pipe cannot be less than I-steel
Web thickness；
Step 2: determine that overhanging I-steel telescopic mounting is specific according to builder's jack special construction plan floor plan
Then position, the pre-buried anchor bolt 1 before 7 structural slab concreting 5 of overhang layer are used overhanging I-steel telescopic mounting in advance
1 fixed structure plate face of anchor bolt is buried, and places wooden box 6 in the concrete walls position of lap-joint, it is scalable to be wrapped in overhanging I-steel outside
2 outside of device rectangular steel pipe, and there are the gaps 30mm；
Step 3: the outer of I-steel 3 in overhanging I-steel telescopic mounting is adjusted by arrangement and method for construction and chooses length, choosing length outside must not
Greater than the 2/3 of I-steel overall length, and in such a way that the limit hole on 3 web of 2 long side of rectangular steel pipe and I-steel is inserted into lock
Form limiting device 4, it is ensured that I-steel 3 is difficult to slide, is then overhang on I-steel outside and sets up external scaffolding；
Step 4: after outer builder's jack is removed, first opening limiting device 4 and be contracted to I-steel 3 in rectangular steel pipe 2,
Then pre-buried fixing bolt 1 is dismantled, it can be by recycling and reusing one by one in building；
Step 5: inspecting for acceptance, and the construction of setting and connection of rod piece etc. should meet the requirement of specification and scheme.Such as overhang foot hand
Frame scaffolding height is more than limit value, is proved by the stringent organizes expert of related request.
Overhanging I-steel telescopic mounting is fixed on structure plate face with cast-in fixing bolt first by the present invention, and in lap-joint
Wooden box is placed in concrete walls position, is wrapped on the outside of overhanging I-steel telescopic mounting rectangular steel pipe outside；Then arrangement and method for construction tune is pressed
The outer of steel I-beam chooses length in section overhanging I-steel telescopic mounting, is fixed using limiting device.It is realized not by the method
It can be returned from building interior with Cantilever Beams flexible arrangement under operating condition, and after overhanging I-steel telescopic mounting shortens after outrigger dismounting
It receives, is greatly reduced overhanging I-steel and removes security risk.The construction method is guaranteeing construction safety, and flexible operation is easy, adds
Fast construction speed facilitates turnover, save the cost.
