Abstract

The utility model discloses a concrete column member, which comprises a concrete column body and a rib cage embedded in the concrete column body; the concrete column member consists of the concrete column body, the rib cage embedded in the concrete column body and a chopped fiber reinforcing area; the rib cage consists of interlaced ribs which respectively extend along the concrete column body vertically and extend along the cross section of the concrete column body; the chopped fiber reinforcing area consists of the chopped fibers which are vertically arranged along the concrete column body; and the ribs of the rib cage extending along the vertical direction of the concrete column body are wrapped in the chopped fiber reinforcing area. The utility model has the advantages of high bearing capacity, excellent anti-crack performance, low cost of the concrete member and simple technique of preformed components, and the electrostatic shielding function, the anti-radiation function and the anti-corrosion function of the concrete member are enhanced.

Description

A kind of concrete column type member

Technical field

The utility model relates to a kind of concrete component, particularly a kind of concrete column type member of fiber reinforcement stress-bearing capability.

Background technology

In construction work, be extensive use of prefabricated component and fitting, to improve construction project efficient, reduce cost, generally strengthen concrete and make by the configuration reinforcement net, but because reinforcing bar is a metal, be easy to get rusty, can not satisfy requirement permanently effective, economic security at aspects such as cracking resistance, radiation proofs.

The utility model content

The purpose of this utility model provides the concrete column type member of a kind of bearing capacity ability height, cracking resistance height, antistatic shielding.

In order to achieve the above object, concrete column type prefabricated units of the present utility model are made up of concrete column 1, the chopped strand enhancement region 3 that is embedded in the muscle cage 2 of described concrete column inside and is embedded in described concrete column inside, described muscle cage 2 runs through whole concrete column, by forming along the longitudinally extending muscle of described concrete column 1 with along the muscle of the stretching, extension of the cross section of described concrete column 1 of being interweaved; Described chopped strand enhancement region 3 is the zone that concrete column 1 inner concrete and chopped strand mix, and described muscle cage 2 is along the longitudinally extending muscle coating of described concrete column 1 and the inside of described chopped strand enhancement region 3.This structure design, on the one hand, utilize the muscle cage to be embedded in inside concrete, concrete stress-bearing capability is strengthened, cracking resistance improves, and on the other hand, utilizes the muscle that stretches on muscle cage concrete cylinder is vertical to coat the chopped strand enhancement region on every side, make the stressed dispersion that is subjected to chopped strand of muscle cage, thereby strengthened the bearing capacity and the cracking resistance of concrete component greatly.

Described muscle cage 2 is at least four along the quantity of the muscle of the longitudinal extension of above-mentioned concrete column 1, is positioned at the position near the surface of described concrete column 1.Chopped strand enhancement region 3 can also can be provided with and extend to whole concrete column according to the requirement setting of different building materialss or processing technology along the width of the cross section of concrete column 1.It also can be prestressed that described muscle cage 2 can be designed as non-prestressed.

Described chopped strand is that length is the fibre of 0.5-50mm.

The material of described muscle cage 2 can be metal and nonmetal; Described chopped strand is nonmetal chopped strand.This design can avoid using metallic fiber muscle cage to cause electrostatic screen.

The material of non-metallic fibers silk and chopped strand specifically can be carbon fiber, aramid fiber, polyethylene fibre, basalt fibre etc.Be preferably basalt fibre, it is anticorrosive to utilize basalt fibre to have, the performance of high temperature resistance, and cost reduces greatly.

Design based on said structure, the utlity model has bearing capacity height, characteristics that cracking resistance is good, reduced concrete component cost, simplified the technology of prefabricated units, also strengthen concrete component electrostatic screen, radiation proof, function such as anticorrosive simultaneously, have good performance and make higher specific use member of the protective materials of structural element, military applications of its pier stud that can be used for bridge, urban road and highway, anti-radiation building (constructing) thing and member and other life requirements etc.

The specific embodiment

As depicted in figs. 1 and 2, be concrete column type member of the present utility model, this concrete column type member is made up of concrete column 1, the chopped strand enhancement region 3 that is embedded in the muscle cage 2 of described concrete column inside and is embedded in described concrete column inside;

Described muscle cage 2 runs through whole concrete column, by forming along the longitudinally extending muscle of described concrete column 1 with along the muscle of the stretching, extension of the cross section of described concrete column 1 of being interweaved; Described chopped strand enhancement region 3 is the zone that concrete column 1 inner concrete and chopped strand mix, and described muscle cage 2 is along the longitudinally extending muscle coating of described concrete column 1 and the inside of described chopped strand enhancement region 3.This structure design, on the one hand, utilize the muscle cage to be embedded in inside concrete, concrete stress-bearing capability is strengthened, cracking resistance improves, and on the other hand, utilizes the muscle that stretches on muscle cage concrete cylinder is vertical to coat the chopped strand enhancement region on every side, make the stressed dispersion that is subjected to chopped strand of muscle cage, thereby strengthened the bearing capacity and the cracking resistance of concrete component greatly.

Described muscle cage 2 is at least four (present embodiment is four) along the quantity of the muscle of the longitudinal extension of above-mentioned concrete column 1, is positioned at the position near the surface of described concrete column 1.Chopped strand enhancement region 3 can also can be provided with and extend to whole concrete column according to the requirement setting of different building materialss or processing technology along the width of the cross section of concrete column 1.It also can be prestressed that described muscle cage 2 can be designed as non-prestressed.

Described chopped strand is that length is the fibre of 0.5-50mm.
