Abstract
The utility model provides a detachable tower crane foundation. The detachable tower crane foundation comprises steel lattice columns and a concrete base, wherein the steel lattice columns are fixed on the concrete base, horizontal supports and cross supports are arranged among the steel lattice columns. The detachable tower crane foundation is characterized in that each steel lattice column is composed of 3-8 column round pipes which are connected in sequence, the lower portions of the column round pipes located at the bottom end extend into the concrete base, and slurry leakage holes are formed in the column round pipes. Each steel lattice column is composed of the column round pipes, and all the column round pipes except for the two column round pipes at the topmost end and the bottommost end can be recycled, so that the reutilization rate of the steel lattice columns is as high as 75%. Compared with other tower crane foundations, the reutilization rate is obviously improved, the adjacent column round pipes are connected through small round pipes, bolts and nuts, and are convenient to assemble and disassemble. The horizontal supports and the cross supports are connected through support connecting plates and the column round pipes, are all of a detachable structure, are all reusable, and can be conveniently detached and installed by workers.
Description
Technical field
The utility model belongs to technical field of buildings, relates in particular to a kind of detachable tower crane basis.
Background technology
The fixed type tower crane crane is widely used in modern industry and the civilian construction, is mainly used in solving the vertical transport problem in the building operations.In order to guarantee the normal safe operation of tower crane, tower crane must be fixed on the tower crane, thereby tower crane must have enough intensity and resistance to capsizing and anti-shear ability, and tower crane can not destroy the foundation structure of building facilities simultaneously.But the concrete amount of existing tower crane is higher, quantity of reinforcement is large, and drop into long in time limit from constructing to, safety is low, can not reuse, after finishing, construction becomes the engineering refuse or because of other professional constructions such as this base position cause influence outdoor water supply and sewerages, need complete removal to clear, produce building waste and cause waste and environment pollution and integrated planning.For this reason, Chinese patent 201110404403.9 discloses a kind of superposed tower crane foundation, it is characterized in that: this tower crane comprises complex root steel lattice column, and the bottom of described steel lattice column is fastening to be inserted in the cast-in-place concrete pile, and the top of described steel lattice column is provided with a steel lattice column head protector; Two lower floor's steel case beams are anchored on described steel lattice column head protector; Two upper strata steel case beams vertically are superimposed on described lower floor steel case beam.This tower crane has good resistance to overturning, anti-subversiveness, and levels steel case beam is reusable.But the construction convenience of this patent is good not, and the recycling rate of waterused of material is also lower.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of detachable tower crane basis, comprise steel lattice column and concrete bed, described steel lattice column is fixed on the concrete bed, be provided with horizontal support and cross support between described steel lattice column, it is characterized in that described steel lattice column is comprised of the 3-8 root post limb pipe that connects successively, concrete bed is stretched in the described post limb pipe bottom that is positioned at the bottom, and is provided with slurry leakage hole thereon.
Be provided with reinforcing cage in the described concrete bed, described reinforcing cage is connected with described post limb pipe by reinforcing bar.
Described post limb pipe two ends are respectively equipped with 8-16 little pipe, and the described little pipe of adjacent described post limb pipe is bolted.
Described post limb pipe two ends are respectively arranged with 12 described little pipes.
Described post limb pipe is provided with the support and connection plate, and is connected with cross support with described horizontal support by described support and connection plate.
The spacing of described steel lattice column is 2-3.5 rice.
The length of described post limb pipe is 2.4-2.7 rice.
The beneficial effects of the utility model are: the steel lattice column is spliced with post limb pipe by many, except two post limb pipes of top and lowermost end, remaining post limb pipe can be recycled, can reach 75% so that the recycling rate of waterused of steel lattice column is the highest, compare with other tower cranes, recycling rate of waterused obviously improves; Be connected with bolt and nut by little pipe between adjacent post limb pipe, assembling, convenient disassembly utilize the workman to finish.Horizontal support is connected with post limb pipe by the support and connection plate with cross support, and horizontal support and cross support are demountable structure, all can reuse, and workman's dismounting is also convenient.Fully take into account the stability of structure, the length of post limb pipe is set to 2.4-2.7 rice, and quantity is defined as the 3-8 root, so that the utlity model has good resistance to overturning and anti-subversiveness.
Description of drawings
Fig. 1 is structural representation of the present utility model.
