Abstract

The utility model discloses a concrete beam frame member, which comprises a concrete beam body, ribs embedded inside the concrete beam body and extending in the longitudinal direction of the concrete beam body, and a chopped fiber reinforcement area, wherein the chopped fiber reinforcement area is formed by chopper fibers randomly distributed in the concrete beam body, and the ribs are wrapped inside the chopped fiber reinforcement area. The concrete beam frame member provided by the utility model has the characteristics of great bearing ability, good anti-cracking performance, low cost, and process simplification of prefabricated parts; and meanwhile the functions of electrostatic screening, radiation protection and corrosion resistance of the concrete beam frame member are enhanced.

Description

A kind of concrete beam type member

Technical field

The utility model relates to a kind of concrete beam type member, particularly a kind of concrete beam 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.

Building structure mostly is the strip supporting member of horizontal direction with beam.Can bear the vertical load of along continuous straight runs distribution and the action effect of moment of flexure.

The utility model content

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

In order to achieve the above object, concrete beam type prefabricated units of the present utility model by concrete beam body 1, be embedded in forming of described concrete beam body inside along the longitudinally extending muscle 2 of described concrete beam body and the chopped strand enhancement region 3 that is embedded in described concrete beam body inside, described chopped strand enhancement region 3 is the zone that concrete beam body 1 inner concrete and chopped strand mix, promptly be made up of to the chopped strand of arranging the unrest along described concrete beam body 1, described muscle 2 coats the inside with described chopped strand enhancement region 3.This structure design, on the one hand, utilize the basalt fibre muscle to be embedded in inside concrete, concrete stress-bearing capability is strengthened, supporting capacity improves, and on the other hand, utilizes to coat the chopped strand enhancement region, make the stressed dispersion that is subjected to chopped strand of muscle, thereby strengthened the bearing capacity and the cracking resistance of concrete component greatly.

Described muscle 2 runs through whole concrete beam body, along the unidirectional layout of the longitudinal direction of described concrete beam body 1.

The quantity of the muscle 2 of every described concrete beam body 1 is at least 2, is positioned at the position near the surface of described concrete beam body 1.Chopped strand enhancement region 3 can also can be provided with and extend to whole concrete beam body according to the requirement setting of different building materialss or processing technology along the width of the cross section of concrete beam body 1.It also can be prestressed that described muscle 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 2 is the non-metallic fibers muscle; 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 muscle and chopped strand specifically can be carbon fiber, aramid fiber, polyethylene fibre, continuous basalt fiber etc.Be preferably continuous basalt fiber, promptly the non-metallic fibers muscle is the continuous basalt fiber muscle, and chopped strand is a basalt chopped fiber.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 bending resistance component 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 shown in Figure 1, be concrete beam type member of the present utility model, this concrete beam type member by concrete beam body 1, be embedded in forming of concrete beam body inside along the longitudinally extending muscle 2 of concrete beam body 1 and the chopped strand enhancement region 3 that is embedded in concrete beam body inside; Concrete beam body is the rectangular column in cross section.

Muscle 2 runs through whole concrete beam body, can select unidirectional or bidirectional arrangements; Chopped strand enhancement region 3 is the zone that concrete beam body 1 inner concrete and chopped strand mix, promptly be made up of to the chopped strand of arranging the unrest along concrete beam body 1, basalt fibre muscle 2 is along the longitudinally extending muscle coating of described concrete beam body 1 and the inside of described chopped strand enhancement region 3.

This structure design, on the one hand, utilize muscle to be embedded in inside concrete, concrete stress-bearing capability is strengthened, supporting capacity improves, and on the other hand, utilizes to coat the chopped strand enhancement region, make the stressed dispersion that is subjected to chopped strand of muscle, thereby strengthened the bearing capacity and the cracking resistance of concrete component greatly.

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

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

The material of muscle 2 is the non-metallic fibers muscle; Described chopped strand is nonmetal chopped strand.The material of nonmetal chopped strand muscle and chopped strand specifically can be carbon fiber, aramid fiber, polyethylene fibre, continuous basalt fiber etc.Be preferably continuous basalt fiber, in the present embodiment, the non-metallic fibers muscle is the continuous basalt fiber muscle, and chopped strand is a basalt chopped fiber.It is anticorrosive to utilize basalt fibre to have, the performance of high temperature resistance, and cost reduces greatly.This design can avoid using the metallic fiber muscle to cause electrostatic screen.
