Description

A kind of single-pile elevated bearing-platform and anchor cable tower-crane foundation structure
Technical field
The utility model is related to a kind of single-pile elevated bearing-platform and anchor cable tower-crane foundation structure, belongs to the realm of building construction.
Background technology
Existing tower crane form is:Independent cushion cap foundation, rood beam basis, Pile-supported stand foundation and lattice column are high-order Cushion cap foundation.Independent cushion cap foundation and rood beam basis is typically disposed in below foundation excavation face, and basic earthwork is constructed after excavating, It has the disadvantage that foundation ditch needs slope shoveling, security protection and backfilling of earthwork, and operation side is big, requires high to subsoil.Pile Stylobate plinth be solve natural foundation bearing capacity it is not enough in the case of and a kind of tower crane form for using, usually 1-4 roots irrigate Stake, it has the disadvantage that foundation ditch needs slope to cut the earth, and security protection and the backfill earthwork, construction working face are larger, and cost is higher.Lattice pillar height Position cushion cap foundation is used in deep basal pit, passes through in basement architectural engineering, the base form saves earth excavation, bank protection, Backfilling of earthwork, but cost itself is high.
Existing tower crane form though be applicable the architectural engineering of different characteristics, exist be not be exactly cost height more than process Problem, and site condition there are certain requirements.Narrow and small to construction area site condition, foundation pit supporting pile has been constructed, basement Exterior wall is nearer with support pile, and require cost it is low be factor that each building enterprise considers, current tower crane form is difficult to The requirement of condition of compatibility change.
Utility model content
The purpose of this utility model is to overcome the problem of above-mentioned prior art is present and shortcoming high-order there is provided a kind of single pile Cushion cap and anchor cable tower-crane foundation structure.The utility model greatly reduces construction costs using single pile, cushion cap and anchorage cable design;It is logical Crossing single pile, cushion cap and anchorage cable design is realized after foundation pit supporting pile excavated, and height can not be ensured simultaneously by solving existing tower crane The problem of stability and high efficiency positioning peace are torn open, can meet tower body antidumping, resistant slide power, good integrity, it is to avoid later stage expense And potential safety hazard;Solve small in operation side, it is adaptable to which different soil properties, foundation pit supporting pile have been excavated, and face side tower crane base at it Plinth is constructed;Its structure and its construction method are simple, and technology is easy to grasp and implemented.
Scheme of the present utility model is as follows:A kind of single-pile elevated bearing-platform and anchor cable tower-crane foundation structure, including a reinforcing bar Cast-in-place concrete pile, reinforced concrete pile cap and tower crane section;
Described deposited reinforced concrete pile is arranged on below excavation face, described deposited reinforced concrete pile upper end anchoring In reinforced concrete pile cap;
Pre-buried tower crane section in described reinforced concrete pile cap;Described tower crane section and tower body are affixed into one Body;
Anchor cable is passed through in also pre-buried two sleeve pipes in described reinforced concrete pile cap, described sleeve pipe;
Tensioning termination is fixedly installed in tower body side on described reinforced concrete pile cap, and anchor cable one end is solid through tensioning termination It is scheduled on gooseneck, described gooseneck is fixed on tensioning termination;The anchor cable other end is embedded in the earthwork.
Further, it is provided with steel reinforcement cage, described reinforced concrete pile cap and sets in described deposited reinforced concrete pile Cushion cap reinforcing bar is equipped with, by concrete-placing reinforcing steel bar cage, cushion cap reinforcing bar, deposited reinforced concrete pile, armored concrete is formed and holds Platform simultaneously anchors both.
Further, described sleeve pipe is obliquely installed, and slip casting in sleeve pipe so that anchor cable is fixed.
Further, in addition to the hat fine strain of millet for being arranged on the support pile of earthwork side, being arranged on support pile upper end has been excavated.
Further, described support pile is locked by anchorage cable stretching.
Further, plain concrete load transfering strip is set under basement bottom board.
The utility model compared with the prior art, has the following advantages that and beneficial effect:
(1)Clearly, the utility model solves ground endurance not enough using pile foundation, mainly improves its bearing capacity, profit for power transmission With anchorage cable stretching, tower crane resistance to capsizing, good integrity are improved;
(2)Consider compared to tower crane or building beyond the region of objective existence slope installation tower crane in basement is installed, including tear open Unload, backfilling of earthwork and the envelope expense such as floor have its good comprehensive benefit.
Brief description of the drawings
Fig. 1 is the side diagram of the utility model foundation structure.
Embodiment
The utility model is described further with reference to embodiment.
A kind of single-pile elevated bearing-platform and anchor cable tower-crane foundation structure, including deposited reinforced concrete pile 1, a reinforced concrete Native cushion cap 2 and tower crane section 3;Deposited reinforced concrete pile 1 is arranged on below excavation face, deposited reinforced concrete pile upper end anchor Gu and in reinforced concrete pile cap 2;Pre-buried tower crane section 3 in reinforced concrete pile cap 2;Tower crane section 3 and tower body 8 are affixed Integrally;Anchor cable 5 is passed through in also pre-buried two sleeve pipes 4 in reinforced concrete pile cap 2, sleeve pipe 4;Tower on reinforced concrete pile cap 2 Tensioning termination 6 is fixedly installed in body side, and the one end of anchor cable 5 is fixed on gooseneck 7 through tensioning termination 6, and gooseneck, which is fixed on, to be opened On pull end head;The rope other end of anchor 5 is embedded in the earthwork.
The utility model is provided with steel reinforcement cage, reinforced concrete pile cap in deposited reinforced concrete pile and is provided with cushion cap Reinforcing bar, by concrete-placing reinforcing steel bar cage, cushion cap reinforcing bar, forms deposited reinforced concrete pile, reinforced concrete pile cap and by two Person anchors.Sleeve pipe tilts 20 degree of settings, and slip casting in sleeve pipe so that anchor cable is fixed.The utility model is also in earth excavation side Face sets some support piles 11, each support pile surface spray anchor armored concrete face, and is locked by twice anchorage cable stretching.Supporting Stake upper end has poured hat fine strain of millet.
The utility model deposited reinforced concrete pile diameter avoids original support pile anchor cable, and same twice anchor cable avoids original Support pile anchor cable position.If under the premise of twice anchor cable anchorage is unappeasable, one of anchor cable can be increased on support pile, really Protect its safety.To ensure to set plain concrete load transfering strip 10, resistance soil under the stability of original stake of excavation supporting, the bottom plate of basement 9 Pressure and power of toppling.
In the utility model single-pile elevated bearing-platform and anchor cable tower-crane foundation structure, tower crane section and bolt use Q235- B, anchor cable is prestress anchorage cable, and welding rod uses E43 types, and weld seam reaches second-order weld quality requirement.
Although detailed description is given to embodiment of the present utility model above and is illustrated, it should be noted that It is that we can carry out various equivalent changes and modification according to conception of the present utility model to above-mentioned embodiment, produced by it Function still covered without departing from specification spirit when, all should be within protection domain of the present utility model.
