Abstract
本实用新型涉及一种桥梁、水利工程和海港码头等混凝土加固结构用预应力纤维树脂复合筋。该复合筋包括截面较小的环氧树脂或环氧砂浆棱柱体和FRP筋或FRP板条，FRP筋或FRP板条埋植于截面较小的环氧树脂或环氧砂浆棱柱体中，所述的FRP是CFRP、GFRP、BFRP或AFRP。本实用新型由于采用环氧树脂或环氧砂浆制备成棱柱体，故具有质量轻的优点，对加固后构件的自重改变不大，很好的提高了加固的效果。另外，本实用新型还具有可进行工厂预制和定制、其张拉质量和力学性能能得到严格控制等优点。
The utility model relates to a prestressed fiber resin composite reinforcement used for concrete reinforcement structures such as bridges, water conservancy projects and seaport wharves. The composite reinforcement includes epoxy resin or epoxy mortar prisms with smaller cross-sections and FRP tendons or FRP laths, and the FRP tendons or FRP laths are embedded in epoxy resins or epoxy mortar prisms with smaller cross-sections. Said FRP is CFRP, GFRP, BFRP or AFRP. Because the utility model adopts epoxy resin or epoxy mortar to prepare prisms, it has the advantages of light weight, and the self-weight of the reinforced components does not change much, which greatly improves the effect of reinforcement. In addition, the utility model also has the advantages of factory prefabrication and customization, and its tension quality and mechanical properties can be strictly controlled.
Description
Technical field
The utility model relates to concrete strengthening structures such as a kind of bridge, hydraulic engineering and sea port dock pre-stress fibre resin compounded muscle.
Background technology
At present, domesticly carry out reinforced concrete structure to reinforce main the employing be the method for fibre sheet material (FRP) " top layer mounting method " reinforced concrete structure, but this method is difficult to the FRP material is applied prestressing force, thereby can't make full use of the intensity of carbon fiber plate, and be difficult to the distortion of suppress structure and the development in crack, and adopt the method that increases the carbon fiber plate use amount to come the distortion and the crack of control structure, its high-intensity advantage and economic benefit have not existed again.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of light weight, consolidation effect good, can carry out prefabrication and customization, its stretch-draw quality and mechanical property can obtain strict control, be specially adapted to pre-stress fibre resin compounded muscle that concrete structure is reinforced, solved the problem that above-mentioned prior art exists.
The technical scheme that solves the problems of the technologies described above is: a kind of pre-stress fibre resin compounded muscle, this compound muscle comprise epoxy resin or epoxy mortar prism and FRP muscle or FRP lath, and FRP muscle or FRP lath are imbedded in epoxy resin or the epoxy mortar prism.
Described FRP muscle is CFRP muscle, GFRP muscle, BFRP muscle or AFRP muscle.
Described FRP lath is CFRP lath, GFRP lath, BFRP lath or AFRP lath.
Owing to adopt said structure, the utlity model has following beneficial effect:
(1) the utility model forms the less pre-stress fibre resin compounded ribs cylinder in cross section owing to adopt the pre-stress fibre muscle to embed in epoxy resin or the epoxy mortar, so pre-stress fibre resin compounded muscle light weight, the deadweight of reinforcing the back member is changed not quite, well improved the effect of reinforcing.
(2) pre-stress fibre resin compounded muscle can carry out prefabrication and customization, the on-the-spot installation, and compound rib prestressed stretch-draw quality and mechanical property can obtain strict control, need not site operation prestressing force.
(3) pre-stress fibre resin compounded muscle sectional dimension is little, and directly subsides or embedding outward is attached to strenthening member surface or inner, can not change the sectional dimension of former member after the reinforcing.
Below, the technical characterictic to the pre-stress fibre resin compounded muscle of the utility model is further described in conjunction with the accompanying drawings and embodiments.
Description of drawings
Fig. 1～Fig. 3: the utility model structural representation.
Fig. 1: the main sectional view of looking.
Fig. 2: one of right view.
Fig. 3: two of right view.
Among the figure: 1-epoxy resin or epoxy mortar prism, 2-FRP muscle, 3-FRP lath.
The specific embodiment
Embodiment one:
(referring to Fig. 1～Fig. 2), comprise epoxy resin or epoxy mortar prism 1 and FRP muscle 2 that the cross section is less, the FRP muscle is imbedded in less epoxy resin in cross section or the epoxy mortar prism a kind of pre-stress fibre resin compounded muscle.
The utility model can adopt epoxy resin to prepare prism also can to adopt epoxy mortar to prepare prism, as a kind of conversion of present embodiment, FRP lath muscle can also be imbedded at and form pre-stress fibre resin compounded muscle (referring to Fig. 3) in less epoxy resin in cross section or the epoxy mortar prism.
FRP muscle described in the utility model can be CFRP muscle (carbon fibre bar), GFRP muscle (glass fiber muscle), BFRP muscle (basalt fibre muscle) or AFRP muscle (aramid fiber reinforced plastic bars), and described FRP lath is CFRP lath, GFRP lath, BFRP lath or AFRP lath.
The diameter of the utility model FRP muscle, the size of FRP lath, prestressing force level are determined according to the actual loading of primary structure member.The utility model sectional dimension is determined according to the engineering actual conditions.
Claims (3)
1. pre-stress fibre resin compounded muscle, it is characterized in that: this compound muscle comprises epoxy resin or epoxy mortar prism (1) and FRP muscle (2) or FRP lath (3), and FRP muscle or FRP lath are imbedded in epoxy resin or the epoxy mortar prism.
2. pre-stress fibre resin compounded muscle according to claim 1 is characterized in that: described FRP muscle is CFRP muscle, GFRP muscle, BFRP muscle or AFRP muscle.
