Abstract
A moving supporting frame installation method includes the steps that firstly, setting-out survey of a track center axis is carried out on a foundation, and backing plates are laid on the axis at intervals; secondly, a track is installed on the backing plates and subjected to elevation adjustment, and then track pressing plates are laid for positioning; thirdly, sliding wheels are temporarily fixed to the track, and the bottoms of supporting legs of a supporting frame are spliced into sheets and placed on the sliding wheels, wherein if the supporting frame deviates from the track center axis, the supporting frame is adjusted in place through a temporary fixing part; fourthly, the bottoms of the supporting legs of the supporting frame are fixed, an upper operating surface platform is subjected to block hoisting, and an empty space in the middle is filled up; fifthly, a net frame unit is finally screwed with bolts to be fixed after being wholly installed in place; sixthly, the fourth step and the fifth step are repeated, the body of the supporting frame is moved every time one net frame unit is installed, the process is carried out in this way till the last net frame unit is installed, and then the supporting frame is dismantled. The moving supporting frame installation method is easy to implement and low in cost and has promotional value.
Description
Technical field
The present invention relates to steel structure net rack installing area, be specifically related to a kind of portable bracing frame installation method.
Background technology
Since entering 21st century, the step of China's state-of-the-art technology rapidly strides forward, and building industry scale constantly expands,
Building level have also been obtained the biggest raising, and this just requires that the construction technology used in engineering must increasingly be come advanced, needs
Constantly innovate, so could improve the construction level of enterprise, reduce construction cost, strengthen construction engineering quality.
In the installation process of steel structure net rack, prior art mainly has three kinds of methods: the first is on ground by rack
The most assembled complete, entirety promotes；The second is rack to be divided into several unit, by unit form at installation on ground
Become block, then air translation block on beam column, and centre is covered；The third is to set up crosshead, then carries out height
Empty in bulk.
In the construction method of above-mentioned three kinds of rack engineerings, the hoisting process of first method easily cause rack become
Shape, the extremely difficult control of rack amount of deflection；Second method is too high to beam column built from concrete requirement for bearing capacity, and dynamic load easily causes concrete
Beam column crack, security risk is too high；And the construction cost of the third method is too high, crosshead can not recycle.
Summary of the invention
Present invention aims to above-mentioned the problems of the prior art, it is provided that a kind of portable bracing frame installation side
Method, its construction cost economy, mode of operation rationally, simply, and disclosure satisfy that the requirement of safe construction.
To achieve these goals, the technical solution used in the present invention comprises the following steps:
The first step, on ground setting out survey orbit centre position axis, on axis interval lay backing plate；
Second step, on the backing plate laid attachment rail track is carried out Pass line adjustment, lay rail pressing plate afterwards
Location；
3rd step, sliding wheel is temporarily fixed on track, is assembled into lamellar bottom the supporting leg of bracing frame and is placed on sliding
On wheel；If bracing frame and orbit centre position axis have deviation, it is adjusted making to bracing frame by interim standing part
Put in place；
4th step, it is fixed bottom the supporting leg of bracing frame, upper operating face platform is carried out block lifting, middle mend
Empty；
Carry out twisting eventually fixing by bolt after 5th step, integral installation are in place；
6th step, repeat fourth, fifth step, after often installing a unit truss, the support body of movable supporting frame, successively class
Push away, to removing bracing frame during last unit truss installation.
Zoning is divided into several unit by beam span or axis by described rack, is divided into initial hoisting area and slip region,
Material is entered by region；Described bracing frame is assembled in initial hoisting area or initial cell, in original area lifting, other district by propping up
Support has moved the construction of unit truss.
Described each unit truss before being installed by bracing frame, according to a ball node and three rod members, one
Ball node and four rod members or block are combined.
The support body of support frame as described above is in moving process, and a vollyball node of unit truss lower edge is on bracing frame；Support
After frame moves into place, by screw jack by the ball node jack-up of last row's lower edge of unit truss, make two of linking
The centre of sphere absolute altitude of unit truss ball node is identical.
The operating surface platform span centre on support frame as described above top carries out load inspection, prevents preloading and carries out support body dimension
Protect.
In use, the sliding wheel bottom supporting leg is provided with anti-sliding stop on track fore-and-aft direction to bracing frame
Car stop.
And the staircase of walking upper and lower for operating personnel and corridor it is provided with on described bracing frame.
If described bracing frame runs into sleet or the wind-force extreme weather more than 5 grades, there is hydrops in ground, needs to pass through water
Levelness readjusted by quasi-instrument.
Compared with prior art, the present invention has a following beneficial effect: by installing bracing frame in orbit to net
Frame is divided into unit and installs, and saves and sets up the time that scaffold is spent in the past, decreases interval so that the overall duration
Shorten.Traditional handicraft, when setting up scaffold, needs a large amount of workmen to participate in, and machinery use cost is relatively big, and required steel
Material is many, and during dismounting, spillage of material is excessive, and unit truss, by assembling track and bracing frame, is depended on by the present invention in the same manner
Secondary assembly, dramatically saves on artificial and machinery expenses, and this slide holder can be repeated as construction tool and make in addition
With, it is to avoid steel wastes, reduce the total consumption in rack installation process.The present invention is in work progress, first to propping up
The connection node of support is the most fixing, if bracing frame and orbit centre position axis have deviation, by interim standing part pair
Bracing frame is adjusted being allowed to put in place, carries out twisting eventually fixing by bolt, so prevent from directly welding after integral installation is in place
The dismounting caused is done over again, the interim fixing adjustment being easy to rack.The present invention is simple to operate, economical rationality, has promotional value.

Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings.
Seeing Fig. 1-4, movable type bracing frame installation method of the present invention, by the rack zoning of subdivisional work, is entered by region
Material；By beam span or axis, zoning is divided into unit form, is divided into initial hoisting area and slip region.Bracing frame is assembled in and initially hangs
Dress district or initial cell, original area lifts, other district uses bracing frame to move, the scheme construction installed in situ.In advance by every district
Or steel ball, rod member are put in order used by unit rack each several part, stack neat, at turnover zone, rod member is assembled into a ball three with crane
Bar, ball four bar, block etc., carry out original area or unit rack is installed, after every district or unit install formation rigid structure,
Interim hold-down support, when span is excessive, needs in the middle of rack to support prop；Movable supporting frame, carries out next district or unit
Install；Often moving a district or unit, rack lower edge must have a vollyball on bracing frame, after bracing frame moves into place, uses spiral shell
Last row's lower edge top dome of rack is risen by rotating jack, it is ensured that installing zone or unit and a upper district or unit centre of sphere absolute altitude are same
One absolute altitude.
