Description
Art
The invention belongs to building structure technology field, relate to a kind of fabricated steel pipe concrete profiled pile.
Background technology
Encased structures is that fill concrete is formed in steel pipe, it utilizes steel pipe and the interaction of concrete bi-material in loading process, namely steel pipe is to the effect of contraction of core concrete, concrete is made to be in the state of three dimension stress, thus concrete strength is improved, ductility is improved; Meanwhile, due to concrete existence, can delay or avoid steel pipe too early cripling to occur, ensure giving full play to of steel performance.In the work progress of concrete filled steel tube, steel pipe as the formwork for placing of its core concrete, compared with steel concrete, can save formwork cost, accelerates speed of application.
It is little that the proposition of steel pipe concrete profiled pile has benefited from its sectional dimension, post and body of wall wide thus avoid and build bight and occur that salient angle affects the problem of house usable floor area and house fitting-up.In several years of past, steel pipe concrete profiled pile obtains certain development, also in some Practical Projects, obtains application.Widely used is at present the steel pipe concrete profiled pile that batten plate formula connects or lacing formula connects, the defect of these hetermorphiscal column is that factory process making is very loaded down with trivial details, be unfavorable for the suitability for industrialized production of batch, in addition in-site installation construction weld seam quantity is many, workload is large, and the quality of hetermorphiscal column can not be guaranteed.
Can not realize the problems such as industrialized mass production and in-site installation construction sequence be complicated to solve steel pipe concrete profiled pile, needing to seek one can realize industrialized mass production, on-the-spot again can the steel pipe concrete profiled pile form of Fast Installation construction.
Summary of the invention
The present invention aims to provide a kind of industrialized mass production that can be applicable to, assembly concrete-filled steel tube hetermorphiscal column that job site can be spliced fast.Technical scheme of the present invention is as follows:
Be applicable to a L shape steel pipe concrete profiled pile for suitability for industrialized production, this post comprises steel plate, through stay bolt, concrete; It is characterized in that, described steel plate comprises exterior angle steel plate (5), interior gusset (6) and two limits channel-section steel plate (8), exterior angle steel plate (5) comprises corner part (5-1), two ends (5-2) and two lateral parts (5-3), interior gusset (6) comprises corner part (6-1), two ends (6-2) and two lateral parts (6-3); Two lateral parts (6-3) consistent size of exterior angle steel plate (5) two lateral parts (5-3) and interior gusset (6), offer mutually corresponding bolt hole; Exterior angle steel plate (5) and the corresponding end of interior gusset (6) form L shape hetermorphiscal column afterwards by being welded to connect with limit channel-section steel plate (8), L shape hetermorphiscal column corner and two end cross-sectional are square, two lateral parts (6-3) of interior gusset are fixedly connected with by through stay bolt with two lateral parts (6-3) of exterior angle steel plate, in L shape hetermorphiscal column, be cast with concrete.
Beneficial effect of the present invention is as follows:
(1) suitability for industrialized production is applicable to, convenient processing and manufacture.The L shape pillar of whole building only need process the steel plate of several cross-sectional shape, as long as and correspondingly adjust the size of steel plate according to the size in pillar cross section and floor height.So just can be implemented in bulk production in factory, drastically increase production efficiency.
(2) weld seam quantity is few, and on-the-spot welding workload is little, and speed of application is fast, and the overall performance of hetermorphiscal column is good.Compared with the steel pipe concrete profiled pile connected with batten plate formula conventional in the market or lacing formula, weld seam quantity reduces in a large number, only need in the welding of steel plate junction, welding difficulty also greatly reduces, the residual stress meanwhile brought due to a large amount of welding and the impact of permanent set also reduce a lot, thus the overall performance of hetermorphiscal column is guaranteed.
(3) convenient with wall connecting.Post limit can not be stretched out in the two ends of bolt, but inside post limit, would not affect the connection of post and body of wall like this, makes construction more convenient.
