Abstract
The utility model discloses a prestress hollow square column for a neck bush, comprising an end plate, a steel bar framework, a lining sleeve, a sleeve support and concrete, wherein the concrete is poured and coats the steel bar framework; the end plate comprises an end socket plate and a pile hoop; the pile hoop is arranged in the way of tightening the end socket plate; the steel bar framework comprises a prestress steel bar and a cold-drawing carbon steel wire which are welded fixedly; the lining sleeve is fixed on the sleeve support. The prestress hollow square column has the advantages that the structure is simple; the whole bearing capability is good; the structure is compact; the anti-seismic property is strong; an exposed pipe does not easily occur in the construction process; compared with a prefabricated concrete pile, the cost is low, the performance cost ratio is high, cracking does not easily occur, the application range is wide and the practicability is good.
Description
Technical field
The utility model belongs to the vertical foundation pile of the low cushion cap field of industry or civil building, is specifically related to a kind of neck bush pre-stress hollow square pile.
Background technology
The development of society requires high to various industry, civilian construction foundation; particularly the requirement of foundation pile technology increased than in the past; there is the phenomenon of concrete delamination in the concrete hollow foundation pile of existing centrifugation moulding; air bag vibration moulding pre-stress hollow foundation pile exists air bag unfixing; the problems such as inner circle is irregular, and protective layer thickness is inhomogeneous.And general bearing capacity is not high, easy quick-fried stake, and practicality is relatively poor.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, the neck bush pre-stress hollow square pile that load-carrying properties are good and anti-seismic performance is strong.
The technical scheme that realizes the utility model purpose is a kind of neck bush pre-stress hollow square pile, comprise end plate, cage of reinforcement, liner sleeve pipe, casing support and concrete, described pouring concrete also wraps up described cage of reinforcement setting, described end plate comprises end plate and pile protection hoop, the described end plate setting of described pile protection banding hoop, described cage of reinforcement comprises prestressed steel bar and cold-drawn carbon steel wire, described prestressed steel bar and described cold-drawn carbon steel wire are welded and fixed, and described liner sleeve pipe is fixed on described casing support.
The welding of cold-drawn carbon steel wire or colligation that described casing support is 4mm by diameter form, and described liner sleeve pipe is Q235 spiral welded pipe or pvc pipe.
The thickness of described liner sleeve pipe is 1mm.
Also comprise steel pile tip, described steel pile tip is fixedly installed on the bottom of described cage of reinforcement.
The diameter of described prestressed steel bar is 9.0MM, 10.7MM or 12.6MM.
The quantity of described prestressed steel bar is 8,12,16,20,24 or 28.
Described concrete external surface is 35MM-45MM apart from the thickness of prestressed steel bar.
The utlity model has positive effect: of the present utility model simple in structure, its integrated carrying ability is good, and its compact conformation, anti-seismic performance is strong, non-explosive stake in work progress, and also it is for precast concrete pile, cost is low, cost performance is high, and is not easy cracking, and is applied widely and practicality good.
Description of drawings
For content of the present utility model is more likely to be clearly understood, the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings, wherein:
