Description

A kind of foot joint be connected with frame column for hole digging pile
Technical field
The present invention relates to the foot joint of multi-layer concrete frame construction, particularly a kind of foot joint of being connected with frame column for hole digging pile and construction method thereof.
Background technology
Hand excavated pile is the good foundation structure form of a kind of applicability, have also been obtained and apply widely in multi-layer concrete frame construction, normal employing one pile for one column base form in multistory frame.The diameter of China " technical code for building pile foundation " (JGJ94-2008) regulation hand excavated pile generally must not be less than 800mm; and often can make large-diameter bored pile due to the restriction of geological conditions and the requirement of bearing capacity; the diameter of stake is far longer than 800mm; and the column dimensions of multistory frame structure is all little, the diameter of hand excavated pile is often greater than the catercorner length of cross-section of frame column.The situation of this one pile for one column of top column dimensions is greater than for stake footpath, bottom, invent the connected node of a kind of new stake and post, it fully can meet the requirement of vertical bearing capacity and horizontal resist forces, pile cap can be saved again, thus minimizing construction costs, for whole engineering, economic benefit is considerable, the present inventor applies in multiple engineering, proves reliable, safe.
What the connection of existing hand excavated pile and frame column adopted is that pile cap connects, and hole digging pile is built cushion cap and is connected with pillar by cushion cap, and on cushion cap, build apron piece to increase the globality of hole digging pile.This method good reliability but also there is certain defect, when bearing capacity and safety enough guarantee also build cushion cap and apron piece, will certainly cause unnecessary waste, economic benefits are bad.Existing technology seems and reliably has a surplus, not enough flexibly.
Summary of the invention
The present invention is directed to the deficiency that prior art exists, a kind of hole digging pile of connecting without the need to pile cap and the connection foot joint of frame column and construction method thereof are provided, the inventive method easy construction, firm for pile connecting structure, the building requirements of multi-layer concrete frame construction can be met.
Following technical scheme is adopted for realizing the object of the invention:
A kind of foot joint be connected with frame column for hole digging pile, it is characterized in that, the stake footpath of described hole digging pile is greater than frame column cross section diagonal length, and described foot joint comprises the reinforcing cage one of described hole digging pile tip portion, the reinforcing cage two of the described frame column toe portion stretched in described reinforcing cage one and the concrete with described reinforcing cage one and reinforcing cage two monobloc cast; The reinforcing cage one of described hole digging pile tip portion comprises the pile body be located in stake holes to be indulged muscle, indulges the described pile body that is welded on of muscle indulge default bind reinforcing bar on muscle and pile body spiral stirrup for reference column, and the reinforcing cage two of described toe portion comprises indulges muscle and shaft stirrup with the post of described default bind reinforcing bar bind.
The pile body of reinforcing cage one is indulged muscle and is arranged along the excircle of stake holes, being welded on the described pile body default bind reinforcing bar indulged on muscle is the arrangement of multilayer " well " font, form the centre bore stretched into for reinforcing cage two, the post of described reinforcing cage two indulge muscle centrally the arrangement of hole inner circumferential and with default bind reinforcing bar bind.
The vertical extension that described reinforcing cage two stretches into reinforcing cage one is the diameter that muscle indulged by the described post being not less than 35 times.
The upper end that described pile body indulges muscle is 90 ° of crotches.
The pitch of described pile body spiral stirrup is 100mm.
The spacing of described shaft stirrup is 100mm.
Invention also provides a kind of construction method of the foot joint be connected with frame column for hole digging pile, it is characterized in that, comprise the steps:
(1) muscle is indulged and pile body spiral stirrup carries out colligation by being located at the pile body arranged along the excircle of stake holes in described stake holes, being encrypted the pile body spiral stirrup of described hole digging pile tip portion makes the pitch of institute's shaft spiral stirrup be 100mm, indulge welding on muscle at the pile body of described hole digging pile tip portion and preset bind reinforcing bar, described default bind reinforcing bar indulges muscle for locating described frame column post; Described default bind reinforcing bar is that multilayer " well " font is arranged and forms centre bore; The pile body of described hole digging pile tip portion is indulged muscle, is preset bind reinforcing bar and pile body spiral stirrup formation reinforcing cage one;
(2) post that the centre bore inner circumferential along described reinforcing cage one is arranged is indulged muscle and shaft stirrup carries out colligation, the shaft stirrup of described frame column toe portion is encrypted and makes the spacing of described shaft stirrup be 100mm; Muscle indulged by the post of described toe portion and shaft stirrup forms reinforcing cage two; In the centre bore described reinforcing cage two being stretched into described reinforcing cage one and the vertical extension stretched into is the diameter that muscle indulged by the described post being not less than 35 times; The post of described toe portion is indulged muscle and described default bind reinforcing bar carries out bind;
(3) to concreting in lifts in described stake holes, the entirety that described concrete and described reinforcing cage one and reinforcing cage two are built is described foot joint.
The upper end that described pile body indulges muscle does 90 ° of crotch process.
Hinge structure of the present invention has following technique effect:
1, the present invention is when taking into full account that the horizontal earthquake action of multi-layer concrete frame construction is not very large, direct employing hand excavated pile is connected with suspension column, save pile cap, structure can be made fully to meet the requirement of vertical bearing capacity and horizontal resist forces, make again structure construction simple and convenient, save cushion cap material and labour cost, thus reduce construction costs;
2, under the service condition of the present invention under the specific condition taking into full account hand excavated pile, as built new building existing building is other, because two building intervals are too near, cannot construction stake cushion cap, direct employing hand excavated pile is connected with suspension column, makes construction become convenient feasible.
