Abstract
The invention discloses a PVC tube-based sea sand/concrete column coated with FRP cloth, and relates to a sea sand/concrete column. The column can solve the problems of the prior art that the manufacturing cost of the FRP tube-based sea sand/concrete column is high and the PVC tube-based sea sand/concrete column has poor load-bearing capacity. The technical scheme I is as follows: the FRP cloth is fixedly wound on the whole outer side face of a PVC outer tube, or a plurality of pieces of FRP cloth are fixedly wrapped on the outer side face of a PVC outer tube from up down and at intervals. The technical scheme II is as follows: a PVC inner tube and a PVC outer tube are nested from inside to outside such that the center line of the PVC inner tube and the center line of the PVC outer tube are superposed; FRP cloth is fixedly wound on the whole outer side face of the PVC outer tube, or the plurality of pieces of FRP cloth are fixedly wound on the outer side face of the PVC outer tube from up down and at intervals; and a cavity formed between the PVC outer tube and the PVC inner tube is filled with sea sand/concrete. The PVC tube-based sea sand/concrete column coated with FRP cloth is applied in the field of civil engineering, the PVC tubes coated with the FRP cloth not only serve as a template used in the construction stage but also effectively restrict the inner sea sand/concrete to make the sea sand/concrete in a three-way stress state. The load-bearing capacity of the whole column is improved.
Description
Technical field
The present invention relates to a kind of marine sand concrete coupled column, the invention belongs to field of civil engineering.
Background technology
At present, usually adopt river sand as the sand of concrete fine aggregate, and do not adopt extra large sand.This is that chlorion has corrosiveness to steel such as reinforcing bar, shaped steel, steel pipes because contain chlorion in the extra large sand, and is very unfavorable to member or integrally-built durability and safety.
Along with developing rapidly of China's building trade, the constructional materials consumption is very large, as the contradiction of the river sand shortage of resources of concrete fine aggregate.China's seashore line length, extra large sand aboundresources if extra large sand can be used for building trade, can be alleviated the situation of river sand shortage of resources, the environmental destruction that can avoid exhaustive exploitation river sand to cause.In the coastal area, if extra large sand is used for building trade, can also gather materials on the spot, minimize transport costs, and extra large sand is cheap, can save cost.
At present, utilize FRP pipe and pvc pipe to make outer tube, section builds the marine sand concrete post and has formed FRP pipe marine sand concrete post and pvc pipe marine sand concrete post within it.But FRP pipe cost is high, so that the cost of FRP pipe marine sand concrete post is high; Pvc pipe is low to inner marine sand concrete restraint forces, so that pvc pipe marine sand concrete columns bearing capacity is low.
Summary of the invention
The purpose of this invention is to provide a kind of outer pvc pipe marine sand concrete post that twines FRP cloth, this post can solve existing FRP pipe marine sand concrete post cost height and the low problem of pvc pipe marine sand concrete columns bearing capacity.
The present invention addresses the above problem the technical scheme of taking to have two kinds, is respectively:
Scheme one: twine the pvc pipe marine sand concrete post of FRP cloth outward, described post comprises PVC outer tube, FRP cloth and marine sand concrete; The fixing FRP cloth that twines of the whole lateral surface of PVC outer tube, the perhaps lateral surface of the PVC outer tube fixing FRP of winding of the intersegmental distance cloth of from top to bottom being separated by, the lumen loading marine sand concrete of PVC outer tube.
Scheme two: twine the pvc pipe marine sand concrete post of FRP cloth outward, described post comprises PVC outer tube, PVC inner tube, FRP cloth and marine sand concrete; PVC inner tube and PVC outer tube are set with from the inside to the outside, PVC inner tube and PVC outer tube central lines arrange, the fixing FRP cloth that twines of the whole lateral surface of PVC outer tube, the perhaps lateral surface of the PVC outer tube fixing FRP of winding of the intersegmental distance cloth of from top to bottom being separated by, filling marine sand concrete in the chamber that surrounds between PVC outer tube and the PVC inner tube.
The invention has the beneficial effects as follows: 1, the outer pvc pipe marine sand concrete post that twines FRP cloth of the present invention is because inner no-reinforcing-bar, and outer tube adopts pvc pipe, and its resistance to corrosion is strong, price is low, therefore, has effectively solved the problem of extra large sand corrosion reinforcing bar and steel pipe.2, the pvc pipe that twines FRP cloth outward not only can be used as the template of construction stage, and can operative constraint internal sea sand concrete, makes it be in the three dimension stress state, has improved the bearing capacity of whole pillar.And extra large sand need not to process, and is applied directly in the construction work.3, the present invention equidistantly fixes at the pvc pipe lateral surface and twines FRP cloth, the pvc pipe marine sand concrete post of the made outer FRP of twining cloth is compared with FRP pipe marine sand concrete post, need not to use the FRP material just can effectively retrain marine sand concrete in large area, can effectively save cost.
