Abstract
The invention relates to a lifting mounting method for an inclined steel roof, which comprises the following steps of: 1) arranging a tooling support frame on the ground, and splicing the inclined steel roof to be mounted in the horizontal direction; 2) arranging upper and lower lifting anchorage points on main structures on the two sides of the inclined steel roof and the inclined steel roof; 3) determining the center of gravity of the inclined steel roof; 4) lifting the inclined steel roof for the first time, and keeping static for at least 12 hours; 5) lifting the inclined steel roof for the second time to ensure that high and low ends of the inclined steel roof accord with the set relative height difference to reach an in-position inclination angle; 6) synchronously lifting the upper and lower lifting anchorage points to make the inclined steel roof reach the in-position point; and 7) performing closure, and connecting the inclined steel roof with the mounted structure to realize the mounting of the structure. The method can reduce a splicing support structure of a high-span inclined steel structure, realize low-altitude and small-height difference integral splicing, lift the inclined steel roof integrally for high-altitude closure, reduce construction cost and improve construction efficiency.
Description
Technical field
The present invention relates to a kind of construction technology of building structure installing engineering, particularly a kind of lifting mounting method of inclined steel roof.
Background technology
Development along with infrastructure, the expansion of construction scope, the height and the span of building progressively increase, particularly in large scale industry and civilian construction, as large-scale museum, memorial museum, stadium, hangar etc., the more and more wider model of roof system adopts large span, large area space steel work.Present domestic large span, large area space Steel Structure Installation technology be comparative maturity, and job practices commonly used has: set up all round victory scaffold, the high-altitude spelling of loosing; Installation on ground, the segmental hoisting method; The fixed point assembly unit, slippage installation method in place; Installation on ground, whole lift method etc.
Installation on ground wherein, whole lift method is widely used, and obtains good effect.This method adopts and on ground structure is assembled into integral body, and then whole vertical-lift docks closure with high-altitude structure, finishes the structure installation.Advantage is that a large amount of structure assembly unit work can be finished on ground, reduces frock scaffold consumption, has avoided the installation at high altitude operation, has reduced the difficulty of the safety management of engineering; Because on-the-spot place is bigger, can form multiple spot, multiaspect continuous productive process, accelerate the installation on ground progress, help the control of project installation precision, but adopt the condition of this method operation to be, promote anchor point only allows vertical direction in lifting process displacement down, do not allow the displacement of horizontal direction, cause the steel strand oblique loading between the upper and lower lifting anchor point, cause the disadvantage that stress is concentrated, make mounting structure when promoting first, produce whole swing, have potential safety hazard.
The large span inclined steel roof of some the required installation meanwhile not only high difference of each standard laid down by the ministries or commissions of the Central Government but also the two ends discrepancy in elevation is bigger, need when mounted to be integral at installation on ground earlier, when carrying out the integral body lifting, need set up a large amount of high pin support system and construction operation scaffold in the higher position of structure lower edge design elevation, do not only like this and take a lot of work, time-consuming, also can cause construction cost to increase, lost the characteristics of whole lifting technology.
Summary of the invention
The objective of the invention is to improve the shortcoming of prior art, and provide a kind of and be widely used, the lifting mounting method of safe and reliable, time saving and energy saving, the inclined steel roof that need not to set up a large amount of high pin support systems.
For achieving the above object, the lifting mounting method of a kind of inclined steel roof provided by the invention, undertaken by following step:
1) the frock bracing frame is set on ground, the inclined steel roof of required installation is pressed the horizontal direction assembly unit on the frock bracing frame;
2) inclined steel roof is after finishing by the horizontal direction assembly unit on the frock bracing frame, promotes anchor point being respectively provided on the agent structure of inclined steel roof both sides on few one, and lifting anchor point place is provided with lifting appliance this on; The two side ends of the inclined steel roof after assembly unit is finished is respectively provided to few one and promotes anchor point down, the transverse horizontal respective distances that promotes anchor point on the both sides is less than the horizontal respective distances that promotes anchor point down, and described lifting appliance is connected by steel strand respectively with following the lifting between the anchor point;
3) equalization point of the center of gravity of determining inclined steel roof when promoting inclined steel roof first, the position of this equalization point promote down anchor point with on promote anchor point the ray intersection draw downwards on vertical vertical plane of vertical line;
4) promote inclined steel roof first, after inclined steel roof leaves the frock bracing frame, static at least 12 hours;
5) promote inclined steel roof once more, it is poor to make its high-end and low side meet the relative altitude that sets, and reaches angle of inclination in place, steel strand between the upper and lower lifting anchor point is in be parallel to each other and the state of vertical ground;
6) keep upper and lower lifting anchor point to promote synchronously, inclined steel roof is arrived with regard to the site;
7) close up operation, inclined steel roof is connected and fixed with mounting structure.
Further, described lifting appliance and the described agent structure that goes up the place setting of lifting anchor point is the hinge connected mode, and described lifting anchor point down and described inclined steel roof are the hinge connected mode.
Further, described lifting appliance is a jack, and this jack is computer controlled automatic, hydraulically powered punching jack.
The present invention compared with prior art has following actively useful effect:
1, realized the low empty position assembly unit of oblique level, adopted the mode that is articulated and connected of upper and lower lifting anchor point, solved the stress of steel strand in lifting process and concentrated disadvantage, the structure of required installation can aloft be rotated with regard to bit architecture.
2, when the horizontal level assembly unit of low latitude, its center of gravity is located at head carries equalization point, produce whole swing when avoiding structure to break away from assembling support, get rid of potential safety hazard.
3, be widely used, safe and reliable, time saving and energy saving, need not to set up a large amount of high pin support system and construction operation scaffold.
