Abstract
The invention provides a demountable tower crane foundation which comprises steel grid columns and concrete bases, wherein the two steel grid columns are fixed on the concrete bases, horizontal braces and X-braces are arranged between the steel grid columns, the demountable tower crane foundation is characterized in that each steel grid column comprises 3 to 8 column component round tubes which are sequentially connected, the lower parts of the column component round tubes at the bottoms of thesteel grid columns extend into the concrete bases, and grout leakage holes are formed in the lower parts of the column component round tubes at the bottoms of the steel grid columns. Each steel grid column is formed by splicing a plurality of the column component round tubes, and all column component round tubes, except the column component round tube at the top of each steel grid column and the column component round tube at the bottom of each steel grid column, can be recycled, so that the reutilization rate of the steel grid columns can reach 75 percent, and the reutilization rate of the steel grid columns is increased remarkably compared with that of steel grid columns in other tower crane foundations; adjacent column component round tubes are connected through small round tubes, bolts and nuts, and the assembling and the dismantling are convenient. The horizontal braces and the X-braces are connected with the column component round tubes through supporting connection plates, the horizontal braces and the X-braces adopt demountable structures and can be all recycled, and the dismantling by workers is convenient.
Description
Technical field
The invention belongs to technical field of buildings, relate in particular to a kind of detachable tower crane basis.
Background technology
Fixed type tower crane crane is widely used in modern industry and civilian construction, is mainly used in solving the vertical transport problem in building operations.In order to ensure the normal safe operation of tower crane, tower crane must be fixed on 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 compared with high, quantity of reinforcement is large, and drop into long in time limit from constructing to, safety is low, can not reuse, construction becomes engineering refuse after finishing 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, fastening being inserted in cast-in-place concrete pile in bottom of described steel lattice column, the top of described steel lattice column is provided with a steel lattice column head protector; Liang Gen lower floor steel case beam, is anchored on described steel lattice column head protector; Two upper strata steel case beams, are vertically 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 invention provides a kind of detachable tower crane basis, comprise steel lattice column and concrete bed, described steel lattice column is fixed on concrete bed, between described steel lattice column, be provided with horizontal support and cross support, it is characterized in that described steel lattice column is made up of the 3-8 root post limb pipe connecting successively, concrete bed is stretched in the described post limb pipe bottom that is positioned at bottom, and is provided with slurry leakage hole thereon.
In described concrete bed, be provided with reinforcing cage, 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 support and connection plate, and is connected with described horizontal support and cross 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.
Beneficial effect of the present invention is: steel lattice column is by how to be spliced with post limb pipe, except two post limb pipes of top and lowermost end, remaining post limb pipe can be recycled, make that the recycling rate of waterused of steel lattice column is the highest can reach 75%, compared with other tower cranes, recycling rate of waterused obviously improves; Between adjacent post limb pipe, be connected with bolt and nut by little pipe, assembling, convenient disassembly, utilize workman to complete.Horizontal support is connected with post limb pipe by 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 3-8 root, makes the present invention have good resistance to overturning and anti-subversiveness.
