Abstract
The invention discloses one kind to lift tower crane installation method, including following construction procedure：First one piece of bearing plate is made in tower crane bottom of foundation ditch to be installed, one lifting framework being made up of beam column is set according to the height at foundation ditch bottom to natural ground on bearing plate top again, lifting framework is preferably higher by nature ground, tower crane positioning pedestal is set in lifting frame upper surface, the standard knot of tower crane is finally directly installed on lifting framework according to positioning pedestal.Present invention lifting tower crane installation method can directly be seated the supporting course of bottom of foundation ditch, caving in for foundation ditch is easily caused without being seated in foundation ditch periphery, the tower body of the installation method is more than natural ground simultaneously, basement will not be backfilled and impacted, without doing earth-retaining enclosure wall again around tower crane, and tower crane section is also not in have ponding to invade bubble, thoroughly solving is having bottom of foundation ditch to have ponding to need situation about being drawn water with suction pump to tower crane.
Description
Technical field
The present invention relates to the realm of building construction, particularly belongs to a kind of lifting tower crane installation method.
Background technology
Tower crane is a kind of indispensable crane gear in Building Construction.In work progress, the peace of tower crane
It is the area coverage in ground storehouse according to building to put, economy and carry out after lifting that weight of material etc. is many-sided and considering it is reasonable
Arrangement, tower crane in the presence of many risks, has plenty of because tower crane is near basis when installation, to the excavation on basis
Cause landslide to produce displacement, or uneven sedimentation etc. is produced due to ponding, it is such, it can all cause serious peace
Full accident, while the tower crane having is seated bottom of foundation ditch, periphery needs to make a circle retaining wall, influences the basement earthwork and integrally return
Fill out, continual when bottom of foundation ditch produces ponding tower crane can also be drawn water.A kind of therefore, lifting tower crane base of invention
Plinth installation method is to solve problems.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of lifting tower crane installation method, by using the installation
Method, can solve the problem that because tower crane is on foundation ditch side, excavation of foundation pit and cause foundation ditch the risk caved in occur, tower crane is located
The backfill of the basement earthwork is not interfered with bottom of foundation ditch, while tower crane can be directly installed on more than nature ground, will not be gone out
Existing pit water accumulation influences tower crane and drawn water with suction pump.
In order to solve the above technical problems, the technical solution adopted by the present invention is as follows：
One kind lifting tower crane installation method, includes following construction technology：Foundation ditch 1 is excavated first, hole bottom 2 is smooth
After-pouring concrete cushion, the position of repositioning pre-installation tower crane, release the position line of tower crane bearing plate 3, then formwork,
Plate is wire-tie, and the reinforcing bar for four frame columns 4 for lifting framework 11 is previously inserted in bearing plate 3, then casting concrete；Work as tower crane
After basis reaches form removal condition, the lifting framework 11 on top is started from, lifting framework 11 is rectangular configuration, and by four frameworks
4, four Vierendeel girders 6 of post are formed, and determine that the absolute altitude on nature ground, then plate prick the reinforcing bar of four frame columns 4, and formwork supporting plate, then
The reinforcing bar of four Vierendeel girders 6 is made, the upper surface of lifting framework 11 is embedded into after tower crane section posting 5 is positioned, then is poured mixed
It is solidifying native, after form removal condition to be achieved, form removal；Tower crane of the standard knot 7 of last tower crane directly with lifting framework 11 upper surface
Section posting 5 is connected with high-strength bolt, that is, completes tower crane installation.
Described bearing plate 3 is poured by armored concrete to be formed, and is directly poured in the supporting course of the bottom of foundation ditch 1.
Described lifting framework 11 is made up of reinforced concrete beam column, is poured on bearing plate 3.
The described lifting height of framework 11 is chosen according to the absolute altitude of bearing plate 3 to natural ground, and lifting framework 11 is higher than certainly
Right ground.
After the completion of the underground component 8 at hole bottom 2 is constructed, it can directly carry out the earthwork 9 and backfill, then carry out upper component 10
Construction.
The positioning pedestal of described lifting framework 11 upper surface setting tower crane tower body, positioning pedestal are relative with tower crane tower body
Should.
The invention enables tower crane can directly be seated in bottom of foundation ditch, then directly be lifted tower crane by lifting framework
To more than natural ground, tower crane is avoided near basis, and foundation pit collapse caused by foundation excavation, tower crane is from foundation ditch bottom directly quilt
The influence eliminated after the completion of basement construction to basement backfilling of earthwork is given rise to more than nature ground, will not also allow tower crane
Underground water or the erosion of other ponding are received, eliminates the work drawn water with suction pump to its basis.The tower crane of the present invention
Installation method, it is simple to operate, easily implement, tower crane can be directly cast in the supporting course of bottom of foundation ditch, avoided in base
The operating procedure driven piles is needed in the case of hole periphery geology is bad, while has prevented the risk that tower crane causes foundation pit collapse,
It can adapt to, in most Deep Foundation Pit situation, reduce the security risk in engineering construction, the method has larger
Development prospect.

Embodiment
Referring to accompanying drawing, one kind lifting tower crane installation method, include following construction technology：Foundation ditch 1 is carried out first
Excavate, cheat the smooth after-pouring concrete cushion in bottom 2, the position of repositioning pre-installation tower crane, release determining for tower crane bearing plate 3
Bit line, then formwork, plate wire-tie, the reinforcing bar of four frame columns 4 for lifting framework 11 is previously inserted in bearing plate 3, then is poured
Build concrete；After tower crane reaches form removal condition, the lifting framework 11 on top is started from, lifting framework 11 is rectangle knot
Structure, and be made up of four frame columns, 4, four Vierendeel girders 6, determine that the absolute altitude on nature ground, then plate prick the steel of four frame columns 4
Muscle, and formwork supporting plate, the reinforcing bar of four Vierendeel girders 6 is then made, lifting framework 11 is embedded into after tower crane section posting 5 is positioned
Upper surface, then casting concrete, after form removal condition to be achieved, form removal；The standard knot 7 of last tower crane is directly with lifting framework
