Abstract
The utility model relates to a construction technique of a tower crane foundation, in particular to steel cross girder type dismountable tower foundation. Aiming at the defects of incapable recycling, material wasting, and long construction period of the existing reinforced concrete tower foundation as well as the defects of inconvenient dismounting, high transportation cost and low circulating times of the dismountable concrete tower foundation, the utility model provides a construction method for the steel cross girder type dismountable tower foundation based on the forced characteristics of the tower foundation under various geological conditions; a steel cross girder, a steel bottom board, and a framework girder are used to replace the normal concrete foundation and an overturning moment is balanced by stacking or arranging a pile base or an anchor rod on the bottom of the girder end. The dismountable tower foundation can be repeatedly used, has a short construction period, and is convenient, economic, practical, safe and reliable.
Description
Technical field
The utility model relates to the construction technology of tower crane, relates in particular to a kind of steel cross-beam type demountable tower crane foundation, and full assembling can reuse, reclaim.
Background technology
Existing steel concrete column foot is not recyclable, waste of material, long construction period.As improvement, prefabricated reinforced concrete assembling column foot, existed for many years, can solve recycling and the dead-weight balanced problem of column foot, but its dismounting is inconvenient, the number of turnover is low, cost of transportation (ton kilometre number) far surpasses the cost of transportation of tower crane own, uneconomical, discarded prefabricated section is still building waste, and is not recyclable.
Summary of the invention
The utility model is not recyclable at existing steel concrete column foot, waste of material, long construction period, and the shortcoming that detachable concrete column foot dismounting is inconvenient, freight is high, the number of turnover is low, analyzing column foot on the basis of the loading characteristic under the various geological conditionss, the construction method of a kind of steel cross-beam type demountable tower crane foundation of utility model, replace conventional concrete foundation with steel rood beam and steel sole plate, frame beam, operating mode according to different geological conditionss, use windrow, or establish pile foundation at the bottom of the beam-ends or anchor pole comes the balance overturning moment.Detachable column foot of the present utility model can reuse, construction period is short, convenient, economical and practical, safe and reliable, and head tower base residual value is not devalued renewable recovery.
The technical solution of the utility model is:
A kind of steel cross-beam type demountable tower crane foundation, it is characterized in that by steel rood beam, steel under casing plate and frame beam being that basic building block is formed, the steel rood beam is the main stress member, steel under casing plate is passed in power transmission under the body of the tower reached ground again, or directly reach stake or anchor pole, can take the various combination mode according to different foundation conditions, be equipped with windrow, anchor pole or stake, forming reliable stressed foundation structure, replace existing steel concrete column foot, all is fabricated construction;
Compound mode one: rood beam+pile foundation+frame beam;
Compound mode two: rood beam+steel under casing plate+anchor pole+frame beam+windrow (needing) as safety stock;
Compound mode three: rood beam+steel under casing plate+frame beam+windrow (no pile foundation);
Described steel rood beam is the i iron of band deep floor, it is the basic primary structure member of column foot, its size depends on the column foot tonnage, it is seated on the steel under casing plate, the installation tie point of girder steel and girder steel is located at moment of flexure, the less middle part infall of shearing, and connected mode employing contract mouth adds screw rod, the contract mouth adds pin joint or junction plate adds bolt.
Described steel under casing plate is a similar engineering with steel subgrade case member, and the installation piece of boxboard and boxboard is located under the steel rood beam, and the employing bolt is connected between boxboard and rood beam.
Described frame beam, it is connected with rood beam end, steel under casing crab bolt simultaneously, forms the monolithic stability structure.
As preferably, the installation tie point of girder steel and girder steel is located at moment of flexure, the less middle part infall of shearing.
As preferably, when driving piles, soft foundation selects rood beam+pile foundation+frame beam combination, designs simplification; When the good ground of earth bearing strength, select rood beam+steel under casing plate+frame beam+windrow compound mode for use.
As preferably, adopt the utility model column foot at middle or small tonnage, column foot that turnover rate is high, economic benefit is more remarkable.
The utlity model has following advantage:
1, easy construction, short construction period.
2, all be assembling, the transition cost of transportation is reasonable.
3, number of turnover height, head tower base residual value is not devalued, even also but it uses or the regeneration recovery condemned MAT'L, meet the industrial policy of country's consumption reduction reduction of discharging.
4, economical and practical, can under various foundation conditions, be used in combination.
