Abstract

A latticed column type tower crane foundation comprises a foundation pile and a bearing platform. The foundation pile is formed by four bored piles. The bearing platform is arranged between the bottom surface of a base plate of a basement and the foundation pile in a supporting mode. The four bored piles and a tower crane are connected through four latticed columns. Each latticed column is welded by four steel angles distributed on four corners and batten plates connected between every two adjacent steel angles. The lower portions of the latticed columns are anchored in the bored piles, the middle portions of the latticed columns are anchored with the bearing platform and upward penetrate through the base plate of the basement, and the tops of the latticed columns are connected with a latticed column platform for fixing a tower crane foundation section. Supporting rods are further connected among the upper portions of the four latticed columns. The latticed column type tower crane foundation ensures quality and safety, reduces the construction difficulty of the latticed column type tower crane foundation, ensures project progress, and can be widely applied to building deep foundation pit tower crane construction.

Description

Lattice pillar tower crane
Technical field
The utility model relates to a kind of tower crane, particularly a kind of tower crane that is applicable to deep foundation ditch.
Background technology
Design has basement in the construction project place, and tower crane comes into operation as early as possible as tower crane when being positioned at the basement basis, constructs significant to basement and bracing of foundation pit.The tower crane structure need satisfy performance and the supporting capacity of tower crane itself, and should satisfy design requirement simple for structure, easy construction as far as possible.Have now and excavate the tower crane earthwork in advance, tower crane is dropped on the method at basement bottom board place again, the soil excavation degree of depth is big, complicated geology, and construction risk is big, long in time limit.Have now in the tower crane bottom and the punching concrete pile is set as the method for tower crane, high material consumption is difficult to guarantee concrete strength, and pile body will produce a large amount of building wastes after removing.
The utility model content
The utility model provides a kind of lattice pillar tower crane, solve the existing technical problem that the tower crane difficulty of construction is big, long in time limit, cost is high.
The technical scheme that its technical problem that solves the utility model adopts is:
This lattice pillar tower crane comprises foundation pile and cushion cap, and described foundation pile is made of four bored piles, and cushion cap props up to be located between basement bottom board bottom surface and the foundation pile;
Be connected by four lattice columns respectively between described four bored piles and the tower crane, every lattice column is welded by the batten plate that is distributed in four angle steel of four jiaos and be connected between adjacent two angle steel, the lattice column bottom is anchored in the bored pile, the lattice column middle part is with the cushion cap anchoring and be upward through basement bottom board, the lattice column top connects and is used for the fixedly lattice column platform of tower crane base section, also is connected with support bar between four lattice column tops.
The stake top of described four bored piles embeds cushion cap 100mm at least.
Described cushion cap is made of end face arrangement of reinforcement, bottom surface arrangement of reinforcement, tension rib and base concrete.
Described lattice column is passing basement bottom board place full weld steel plate water-stopping sheet all around.
Described lattice column platform is by the horizontal steel plate that is welded in the lattice column end face, and the triangular steel plate that is welded between horizontal steel plate and the lattice column constitutes.
Described support bar comprises and is connected horizontal brace and diagonal brace between the adjacent lattice column, and is connected the horizontal cross brace between relative two horizontal braces.
Described support bar adopts channel-section steel or angle steel.
The beneficial effects of the utility model are as follows:
The utility model adopt to adopt four bored piles as foundation pile, adopts lattice column to be connected between stake and the tower crane, and the lattice column lower end imbeds that a conduct is connected and fixed a little in the stake, and lattice column can be with the Load Transfer of tower crane to bored pile.Not only quality safety is guaranteed on lattice pillar of the present utility model basis, has also reduced the difficulty of construction of tower crane, has guaranteed programming.
Lattice column is connected with support bar between the top, has improved stability of structure.It is recyclable that lattice column uses up the back material, reduced construction cost.Full weld steel plate water-stopping sheet around the lattice column at sole plate place can guarantee that sole plate is water-tight,
