Abstract
The present invention relates to a structure of the reinforcing bar concrete hoped by a fiber enhanced plastic mesh, which is a system of the structure of the reinforcing bar concrete hoped (FRP) by the fiber enhanced plastic mesh with good stress performance. A basic component of the structure of the reinforcing bar concrete hoped by a fiber enhanced plastic mesh is a reinforcing bar concrete beam column, wherein a component hoop bar is made of a fiber enhanced plastic mesh piece (1), a beam longitudinal bar (2) or a column longitudinal bar (4) is made of a reinforcing bar, and the fiber enhanced plastic mesh piece (1) is wrapped on the outer side of the beam longitudinal bar (2) or the column longitudinal bar (4) for more than one week. The fiber enhanced plastic mesh piece (1) is composed of mesh grids woven by using fiber rope materials and is used as a shearing resisting matched bar of the component, and fiber is single fiber or mixed fiber. The mesh grids woven by using the fiber rope materials are in a rectangle, a rhombus, a triangle or other polygons. The structure of the reinforcing bar concrete hoped by a fiber enhanced plastic mesh is mainly used for the field of civil engineering and is used for enhancing the bending resistance, the shearing resistance, the bearing capacity and the ductility of the reinforcing bar concrete component and accelerating construction speed.
Description
Technical field
The present invention relates to a kind of novel house structural system, it is to improve on former reinforced concrete structure basis, can significantly improve structural element (beam, post) stress performance.
Background technology
Reinforced concrete structure is to use maximum architecture structure forms at present.The general scantling of ordinary reinforced concrete structure is bigger, and should not adopt Materials with High Strength; Prestressed reinforced concrete structure then construction precision requires highly, must be constructed by special pre-stress construction personnel and just can ensure the quality of products, and prestressed reinforced concrete construction can only improve the cracking resistance of structure or member, can not improve bearing capacity.In addition, stirrup colligation workload is bigger in the structure of reinforced concrete, and construction environment is relatively poor.Fibre reinforced plastics (FRP) comprise charcoal fiber (CFRP), glass fiber (GFRP) and aramid fiber (AFRP), because it has advantages such as intensity height, corrosion resistance and good, in construction work, be widely applied in recent years, but because fibre reinforced plastics and concrete bond and anchor property are relatively poor, and cost is higher, limited its range of application greatly, be used in the structural fortification more in field of civil engineering.
Summary of the invention
Technical problem: in order further to improve the mechanical property of reinforced concrete structure, and the range of application of expansion this quality material of fibre reinforced plastics (FRP) in civil engineering, the invention provides a kind of fibre reinforced plastics net hoop reinforcing steel bar concrete structure, this form of structure, it not only can improve the anti-bending bearing capacity and the shear-carrying capacity of member, simplify the construction sequence of reinforced concrete structure, and can solve the bond-anchorage difficult problem between steel concrete and the fibre reinforced plastics (FRP) preferably.
Technical scheme: the technical solution adopted for the present invention to solve the technical problems is: the basic building block of this structure is a reinforced concrete beam column, wherein to adopt fibre reinforced plastics net sheet be fibre reinforced plastics net sheet in fibre reinforced plastics net sheet, the post in the beam to the member stirrup, vertical muscle of beam or the vertical muscle of post adopt reinforcing bar, and fibre reinforced plastics net sheet is indulged more than 1 week of parcel of the muscle outside at beam in the beam; Fibre reinforced plastics net sheet wraps up more than 1 week in the vertical muscle of the post outside in the post.The grid that fibre reinforced plastics net sheet adopts the fiber rope material to be made in the beam constitutes, as the shearing resistance arrangement of reinforcement of member; Described fiber is single fiber or composite fibre.Be that the grid that adopts the fiber rope material to be made into is rectangle or rhombus or triangle.During use fibre reinforced plastics are made various flexible cable materials, be made into the fleece of various shape of a mesh, after the vertical muscle of reinforced concrete members such as beam, post is in place, fleece wrapped up around vertical muscle, twine more than 1 layer as stirrup, then the formwork concreting.
Beneficial effect: the invention has the beneficial effects as follows the simplification work progress, accelerate speed of application.This form of structure, it not only can improve the anti-bending bearing capacity and the shear-carrying capacity of member, simplifies the construction sequence of reinforced concrete structure, and can solve the bond-anchorage difficult problem between steel concrete and the fibre reinforced plastics (FRP) preferably.
This form of structure has been saved the program of artificial assembling reinforcement, can improve speed of application.Because of fiber has pliability and higher-strength preferably, the fleece hoop is better than the plain bars hoop to concrete constraint, and the fiber rope of forming the net hoop is different directions, can limit carrying out of different directions crack, reaches the purpose that improves structural performance.
