Abstract

The utility model relates to a bamboo plastic composite rib concrete beam, especially to a structural beam used for hydraulic structures, bridges, ports in civil engineering and other corrosive environments. The bamboo plastic composite rib concrete beam includes a concrete beam main body. Corner bamboo plastic composite ribs are arranged at four inner angles of the concrete beam main body. A steel stirrup is disposed at the inner side of the concrete beam main body, and a longitudinal steel bar is arranged at the middle of the upper and lower parts of the concrete beam main body. According to the utility model, under a mode of mixed reinforcement of the bamboo plastic composite ribs and the steel bar, the mechanical performance of the concrete beam is improved significantly, and the flexural rigidity and ductility of members can be enhanced. The utility model has the advantage of low cost. China has rich bamboo resources, and the adoption of bamboo plastic composite ribs can save energy and reduce the cost. The utility model also has good corrosion resistant performance. Bamboo plastic composite ribs have good corrosion resistance ability, and can have a service life of more than a hundred years after a proper pretreatment process. Thus, the bamboo plastic composite rib concrete beam is especially suitable to oceans, wet environment, salinate fields, saline-alkali fields and other harsh environments.

Description

A kind of bamboo-plastic combined Concrete Beam Reinforced
Technical field
The utility model relates to a kind of bamboo-plastic combined Concrete Beam Reinforced, particularly the structural beams in a kind of hydro-structure for civil engineering, bridge, harbour and other erosion environment conditions.
Background technology
That if reinforced concrete structure designs is proper, structure rationally, reliable construction quality, can have good durability under the home condition.But in long-term engineering use procedure, usually can affect because of corrosion of steel bar structure functional performance, durability and safety.Be split up phenomenon in order to solve reinforced concrete corrosion and concrete along muscle, a kind of new method adopts continuous fiber reinforced plastic (FRP) material to replace reinforcing bar exactly, but this new-type FRP rebar cost is higher, production process is more complicated, and modulus of elasticity is lower, makes the amount of deflection of its concrete beam reduce and the crack width increase.
Summary of the invention
In order to overcome above-mentioned defect, the purpose of this utility model is to provide the bamboo-plastic combined Concrete Beam Reinforced in a kind of hydro-structure, bridge, harbour and other erosion environment conditions that can be used in civil engineering.
In order to achieve the above object, the utility model is by the following technical solutions:
A kind of bamboo-plastic combined Concrete Beam Reinforced, it comprises the concrete beam main body, four interior angles in the concrete beam main body are provided with the bamboo-plastic combined muscle in bight, in concrete beam main body inboard, are provided with the stirrup muscle, in the stage casing, top and the bottom of concrete beam main body, are provided with longitudinal reinforcement.
Described bamboo-plastic combined muscle is that bamboo, glass fiber, resin and filler etc. are composited.
The beneficial effects of the utility model are:
1, the utility model mixes under the arrangement of reinforcement pattern at bamboo-plastic combined muscle and reinforcing bar, the stress performance of concrete beam be improved significantly, improve flexural stiffness of member, ductility is good.
2, the utility model is cheap.China has abundant bamboo resource, adopt bamboo-plastic combined muscle material can energy conservation, reduce costs, made up again the low weakness of traditional glass steel part transverse strength simultaneously.
3, the utility model Corrosion Protection is good.Bamboo-plastic combined muscle has good corrosion resistant ability, and it is through suitable pretreating process, more than being a century application life, and therefore particularly suitable under the adverse circumstances such as ocean, humidity, salt lick and salt-soda soil.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the side coil schematic cross-section of Fig. 1.
The specific embodiment
Be elaborated below in conjunction with accompanying drawing 1,2 pairs of the utility model:
A kind of bamboo-plastic combined Concrete Beam Reinforced, it comprises concrete beam main body 4, four interior angles in concrete beam main body 4 are provided with the bamboo-plastic combined muscle 1 in bight, in concrete beam main body 4 inboards, are provided with stirrup muscle 3, in the stage casing, top and the bottom of concrete beam main body 4, are provided with longitudinal reinforcement 2.
Described bamboo-plastic combined muscle is that bamboo, glass fiber, resin and filler etc. are composited.
Installation process: first bamboo-plastic combined muscle and longitudinal reinforcement are passed through the colligation of stirrup muscle, then formwork supporting plate, then concreting, treat that concrete reaches the require design that reaches compressive strength, has namely formed bamboo-plastic combined Concrete Beam Reinforced.
