Description
Technical field
The utility model relates to a kind of combined type tower-crane foundation structure.
Background technology
Along with the development of engineering construction; the basement degree of depth and scale increasing; when the horizontal supporting and protection structure of deep foundation ditch of constructing; often can run into the earthwork and also not dig the situation just requiring that tower crane is installed in advance; and tower crane must be installed on basement position, according to traditional pile foundation+concrete bearing platform formula tower crane, that can cause tower crane digs dark intensification; earthwork excavated volume increases, and is unfavorable for the control of project construction progress and cost.
Utility model content
The utility model makes improvement for above-mentioned prior art Problems existing, and namely technical problem to be solved in the utility model is to provide the combined type tower-crane foundation structure that a kind of structure is simple, stability is high.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of combined type tower-crane foundation structure, comprise the foundation ditch being excavated to basement roof from ground, described basement roof offers some preformed holes, described preformed hole internal fixtion has filling pile cage of reinforcement, described filling pile cage of reinforcement welds with lattice column bottom, described lattice column top is welded with cushion cap distributing bar net, and the described online portion of cushion cap distributing bar is welded with tower crane socle pre-embedded bolt and saves with tower crane through tower crane socle pre-embedded bolt and is connected.
Further, described lattice column corner is all welded with angle steel, and two adjacent angular steel lateral surfaces are welded with batten plate.
Further, steel holder is fixed with bottom described lattice column and cushion cap intersection.
Further, cross bar, diagonal web member is welded with between two adjacent lattice columns.
Further, the surrounding side of described basement roof is provided with water blocking tape.
Compared with prior art, the utility model has following beneficial effect: this combined type tower-crane foundation structure effectively reduces project earthwork excavated volume, make project in construction early application plant equipment, decrease cost of labor, and structure is simple, stable, accelerate the progress of project and improve the economic benefit of project.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.

Detailed description of the invention
As shown in Fig. 1 ~ 5, a kind of combined type tower-crane foundation structure, comprise the foundation ditch being excavated to basement roof from ground, described basement roof offers four preformed holes 2, described preformed hole 2 internal fixtion has castinplace pile 3 reinforcing cage, described castinplace pile 3 reinforcing cage welds with lattice column 4 bottom, and described lattice column 4 top is welded with cushion cap 5 distributing bar net, and the online portion of described cushion cap 5 distributing bar is welded with tower crane socle pre-embedded bolt 10 and saves 6 through tower crane socle pre-embedded bolt 10 and tower crane and is connected.
In the utility model, described lattice column 4 four jiaos is all welded with angle steel 41, and two adjacent angular steel 41 lateral surfaces are welded with batten plate 42.
In the utility model, bottom described lattice column 4 and cushion cap 5 intersection, be fixed with steel holder 7.
In the utility model, between two adjacent lattice columns 4, be welded with cross bar 8, diagonal web member 9.
In the utility model, the surrounding side of described basement roof is provided with water blocking tape 11.
Specific construction process of the present utility model is as follows:
(1) before excavation of foundation pit, tower crane foundation position of having good positioning, piling, fixing castinplace pile 3 reinforcing cage;
(2) process four lattice columns 4 to be inserted respectively in the reinforcing cage of four castinplace piles 3 and to weld, insertion depth is determined after requiring calculating according to actual loading, after lattice column 4 has welded with the reinforcing cage of castinplace pile 3, at the inner concreting of castinplace pile 3 template to form castinplace pile 3, described lattice column 4 and castinplace pile 3 stable connection;
(3) in Excavation Process, the progress that the diagonal web member 9 of lattice column 4 part of combined type tower crane must be cut the earth along with foundation ditch with digging with weldering, until excavation of foundation pit is to basement bottom board place, to ensure the stability of whole foundation structure;
(4) by the leveling of four lattice column 4 capital levelnesss, error is no more than 1/1000;
(5) at lattice column 4 top braiding concrete blinding, concrete bearing platform 5 is made according to the technical requirements of concrete foundation in pillar crane description, and on concrete bearing platform 5 pre-embedded anchoring bolts (fixed supporting leg), when cushion cap 5 concrete strength reaches more than 95%, equipment is marched into the arena installation, and initial setting height(from bottom) must not higher than 30m;
(6) pillar crane installs that rear detection is qualified can come into operation.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
