Abstract
The utility model discloses a foundation of a deep-excavation tower crane, which comprises four concrete pile holes made by adopting concretes and pile steel bars, wherein the four concrete pile holes are arranged below a bottom plate of a basement; four lattice columns are arranged between the bottom plate of the basement and a top plate of the basement; the lower ends of the four lattice columns are inserted in the four concrete pile holes; a horizontal supporting rod and an inclined supporting rod are fixed between every two adjacent lattice columns; bearing steel plates are respectively fixed at the upper ends of the four lattice columns; and the parts of the four lattice columns, which are inserted in the concrete pile holes, are fixed with the pile steel bars. For the foundation of the deep-excavation tower crane, the four lattice columns are well fixed with the pile steel bars in the concrete pile holes; being made of steel, the lattice columns can be dismantled after the whole project is completed and can be used repeatedly; and compared with the prior art, the labor for building and dismantling the foundation of the deep-excavation tower crane is economized and the material cost is saved.
Description
Technical field
The utility model relates to the pylon of a kind of building operations with tower crane, and the basis of a kind of deep foundation ditch tower crane of more specifically saying so belongs to technical field of buildings.
Background technology
At present building trade is along with scale constantly enlarges, super dark super large and long-pending underground foundation ditch is more and more.Large-scale tower crane gear is the necessaries of construction on object of construction production, must install before soil excavation according to the tower crane that engineering properties is installed in the basement scope, and this is a great problem that construction enterprises comparatively face.
The pylon of existing deep foundation ditch tower crane, the general concrete cushion cap basis of adopting, promptly at ground location, just the basement roof position has a platform, have four concrete stakes under the platform, concrete stake and platform are built and are integral, and body of the tower and loop wheel machine, the cushion cap basis of the pylon of the deep foundation ditch tower crane of this structure are installed on platform then, after the completion of whole engineering, need concrete stake between basement roof and the base plate and whole platform are all disposed, and what remove is building waste substantially.Labor intensive not only, but also consume material needs bigger construction cost.
The utility model content
At above-mentioned situation, the problem that the utility model quasi-solution is determined provides the basis of the deep foundation ditch tower crane of a kind of labour that can save construction and material, to save construction cost.
For achieving the above object, the utility model has adopted following technical scheme: a kind of basis of deep foundation ditch tower crane, it comprises four concrete stake holes, described concrete stake hole has concrete and stake reinforcing bar, described four concrete stake holes are below basement bottom board, be provided with four lattice columns between described basement bottom board and the basement roof, insert in four concrete stake holes the bottom of described four lattice columns; Fixed level support bar and inclined support bar between the adjacent lattice column of described four lattice columns, the upper end of described four lattice columns be fixing load-bearing steel plate respectively; Part in the insertion concrete stake hole of described four lattice columns is fixed with the stake reinforcing bar.
Described lattice column is spliced by four angle steel and four steel plates, and described lattice column cross section is square.Two connecting reinforcements are fixed in the outside of the part in described four angle steel insert concrete stake hole respectively, and described two connecting reinforcements are fixed with the stake reinforcing bar respectively.The degree of depth L in four concrete stakes of insertion hole of described four lattice columns is for being not less than 1.5 meters.
Adopt such scheme, four lattice columns on the basis of deep foundation ditch tower crane of the present utility model are well secured with the stake reinforcing bar in concrete stake hole, and the concrete stake that fixedly secures by concrete, in the upper end of four lattice columns respectively fixedly the load-bearing steel plate can build body of the tower and loop wheel machine.Because the lattice column material is steel, can remove after the whole engineering completion in addition, but the repeated multiple times use compared with prior art, had both been saved the labour who builds and remove the basis of deep foundation ditch tower crane, having can the economical with materials cost.
