Abstract
The utility model provides a laminate-type high pile cap tower crane foundation structure which comprises four cast-in-place concrete piles arranged in a foundation pit. The cast-in-place concrete piles penetrate through a foundation mat, a reinforced concrete pile cap is fixedly arranged on pile tops of the cast-in-place concrete piles, a tower crane foundation joint is fixedly arranged in the reinforced concrete pile cap, a plurality of concrete laminate structures are formed on the cast-in-place concrete piles located above the foundation mat, and the cast-in-place concrete piles are arranged in the concrete laminate structures in a penetrating mode. The laminate-type high pile cap tower crane foundation structure well solves the problems that a tower crane is utilized to carry out vertical transportation in the whole process of the construction process of the foundation pit and the tower crane is poor in performance, the tower crane can be installed in advance for operating before engineering piles are constructed or before foundation pit earth excavation, foundation pit excavation time is effectively shortened, work efficiency of foundation pit construction is improved, the foundation pit construction period can be greatly shortened, and advantages for smooth proceeding of follow-up working procedures are provided.
Description
Technical field
The utility model relates to a kind of tower crane structure, particularly relates to a kind of laminated board type highrise pile cap tower crane structure.
Background technology
At present, the comparatively common a kind of mode of large-scale construction method of deep foundation ditch is: before soil excavation, four concrete filled steel tube castinplace piles of elder generation's construction or cast-in-place concrete pile, stake top mark height is located at below the tower crane cushion cap, after treating that tower crane installs, carry out soil excavation again, the castinplace pile of support tower crane successively exposes with the intensification of the soil excavation degree of depth, form destabilizing factor, for addressing this problem, need between four steel tube concrete piles or concrete pile, to form bridging with the steel pipe welding, increase the resistance to overturning of high stake part.Though this method has increased the stability of tower crane, increase welding sequence, increased a large amount of other operations such as steel work welding engineering amount, make tower crane be subjected to certain limitation service time.
Summary of the invention
In view of the existing technical problem that exists, the utility model provide a kind of Stability Analysis of Structures, firmly, the efficiency of construction in the safety, raising foundation ditch, and easy construction, laminated board type highrise pile cap tower crane structure with low cost.
Laminated board type highrise pile cap tower crane structure of the present utility model, comprise four cast-in-place concrete piles that are arranged in the foundation ditch, described cast-in-place concrete pile runs through sole plate, the stake top of described cast-in-place concrete pile is installed with a steel concrete cushion cap, be installed with tower crane joint in the described steel concrete cushion cap, be on the cast-in-place concrete pile of described sole plate top and be formed with plural layer of concrete plated construction, and described cast-in-place concrete pile is arranged in the described layer of concrete plated construction.
The length that described cast-in-place concrete pile is positioned at the following anchoring section of sole plate is not less than 2 with the length ratio that exposes to the revealed section of foundation ditch.
Described layer of concrete plated construction comprises the reinforced mesh of double-layer double-direction.
The utility model makes its beneficial effect that has be owing to adopt above technical scheme:
Behind construction and mounted castinplace pile and concrete bearing platform, earth excavation is built then and is formed the plural layer veneer structure downwards, finishes the installation of tower crane.The utility model is by being arranged on each plated construction layer by layer on four castinplace piles, make tower crane Stability Analysis of Structures of the present utility model, firmly, safe, compare other highrise pile cap easy constructions, with low cost, preferably resolving in the foundation pit construction process overall process uses tower crane to carry out vertical transport, the difficult problem of tower crane poor stability, the engineering stake do not construct or pit earthwork excavation before just can install tower crane in advance and turn round, effectively shortened the excavation of foundation pit time, improved the operating efficiency of foundation pit construction, can shorten the foundation pit construction duration in a large number, carrying out smoothly for subsequent handling provides advantage.
Description of drawings
Fig. 1 is the utility model tower crane structure elevation;
Fig. 2 is the utility model tower crane structural laminate plate structural plan figure.
The specific embodiment
For the benefit of to the understanding of structure of the present utility model, describe below in conjunction with drawings and Examples.
In conjunction with Fig. 1 and shown in Figure 2, laminated board type highrise pile cap tower crane structure of the present utility model, comprise four cast-in-place concrete piles 1 that are arranged in the foundation ditch, become the four directions to arrange, a stake top mark high position is near ground surface, castinplace pile 1 wears in the sole plate 2, the length that every castinplace pile 1 is positioned at sole plate 2 following anchoring sections 11 is not less than 2 with the length ratio that exposes to the revealed section 12 of foundation ditch, guaranteed the stability of castinplace pile 1, and a steel concrete cushion cap 3 has been built in the stake top casting, pre-buried tower crane joint 4 in the concrete bearing platform 3, can make body of the tower and foundation structure is affixed is integral by tower crane joint 4, be on the castinplace pile 1 of sole plate 2 tops and be formed with plural layer of concrete plated construction 5, castinplace pile 1 is arranged in the veneer structure 5, and adjacent layer plated construction 5 is between the upper and lower every being not more than 2m, the every limit of planar dimension exceeds castinplace pile 1 and is not less than 0.5m, thick 250mm, configuration reinforcement diameter are not less than 25mm@150mm double-layer double-direction reinforced mesh, and the strength grade of concrete of veneer structure 5 is not less than C35.
Before the pit earthwork excavation, four cast-in-place concrete piles 1 of elder generation's construction, make castinplace pile 1 through sole plate 2, steel concrete cushion cap 3 is built in stake top casting at four castinplace piles 1, earlier pre-buried tower crane joint 4 is built then before concrete bearing platform 3 is built, and finishes the installation of tower crane, then excavation 500mm is dark downwards earlier around concrete bearing platform, substantially after smooth, lay common composite board, assembling reinforcement net sheet, template around installing then, build and form first floor veneer structure 5, the excavation pit earthwork then is in digging process, whenever dig 2m downwards, according to the identical step plated construction 5 from level to level of constructing, thereby finish the construction of tower crane structure, increased the resistance to overturning of high stake part, by tower crane joint 4 body of the tower is installed on the tower crane structure then, lifts hauling operation.
The utility model is by being arranged on each the layer concrete veneer structure 5 on four cast-in-place concrete piles 1, make tower crane Stability Analysis of Structures of the present utility model, firmly, safe, compare other highrise pile cap easy constructions, with low cost, preferably resolving in the foundation pit construction process overall process uses tower crane to carry out vertical transport, the difficult problem of tower crane poor stability, the engineering stake do not construct or pit earthwork excavation before just can install tower crane in advance and turn round, effectively shortened the excavation of foundation pit time, improved the operating efficiency of foundation pit construction, can shorten the foundation pit construction duration in a large number, carrying out smoothly for subsequent handling provides advantage.
