Abstract
The utility model relates to a compound reinforcing concrete flexural member, which comprises a reinforcing concrete flexural member. The tensile surface of the reinforcing concrete flexural member is adhered with fibre reinforced plastics; the outer sides of the fibre reinforced plastics are adhered with steel plates; U-shaped steel hoops are wrapped in the outer sides of the steel plates and the two adjacent side surfaces of the tensile surface of the reinforcing concrete flexural member; and both tips of the U-shaped steel hoops are anchored with bolts. The utility model has simple structure, can greatly improve the bearing capacity of the flexural member and can improve the rigidity, the ductility, the integrity and the reliability of the flexural member.
Description
Technical field
The utility model relates to a kind of concrete flexural member, relates in particular to a kind of composite consolidation concrete flexural member.
Background technology
China has huge construction market, in industry and civilian construction, many concrete structures are because factors such as the defective of design, construction and the damage in the long-term use, aging and disasters, cause member cracking, the anti-seismic performance of considerable part bad, many problems that influence safety and function of use such as bearing capacity deficiency, need reinforce.In addition because the requirement of building structure storey-adding reconstruction or the change of function of use etc., make the bearing capacity deficiency of original structure need increase substantially bearing of component by the method for reinforcing.
At present in actual reinforcing to concrete flexural member, outer steel bonding plate is reinforced and pasted the fibre reinforced plastics reinforcing is that two kinds of application are comparatively extensive, the method that Study on behavior is comparatively ripe, both respectively have pluses and minuses on to the performance improvement of flexural member: paste the bearing capacity that the fibre reinforced plastics reinforcing method can improve concrete flexural member by a relatively large margin, and easily paste, has the strength-weight ratio height, heat-resisting and corrosion resistance is strong, advantage such as applied widely, but to pasting the member after fibre reinforced plastics are reinforced, the ductility in its cross section reduces significantly, rigidity improves less, and the stripping damage of fibre reinforced plastics takes place easily, destruction has certain emergentness, and the utilization rate of fibre reinforced plastics is lower simultaneously; Outer steel bonding plate reinforcing method reinforcement performance is good, save usage space, easy construction and easily anchoring, the steel-bonded reinforcement member all can keep ductility preferably by being loaded in the destructive process, all be restricted with the steel plate thickness and the number of plies but reinforce, be generally one deck in the actual engineering, thickness makes that its raising to the concrete flexural member bearing capacity is limited between 2mm～6mm.
The utility model content
The purpose of this utility model is to address the above problem and provide a kind of simple in structure, the bearing capacity of flexural member can be improved by a relatively large margin, but also the composite consolidation concrete flexural member of rigidity, ductility and globality and the reliability of flexural member can be improved.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
It comprises concrete flexural member, the tension face of concrete flexural member is pasted with fibre reinforced plastics, the fibre reinforced plastics outside is pasted with steel plate, and the adjacent two sides of tension face of the steel plate outside and concrete flexural member are enclosed with U shaped steel hoop, and the anchoring of U shaped steel hoop two ends has bolt.
Above-mentioned U shaped steel hoop is a plurality of, is provided with at interval on the concrete flexural member length direction between the adjacent two U shaped steel hoops.
Compared with prior art, the utility model has been obtained following technique effect:
1, this utility model is simple in structure, fibre reinforced plastics and steel plate composite consolidation concrete flexural member, both can utilize the easy adhibit quality of fibre reinforced plastics, bearing capacity improves the deficiency that is subjected to steel plate thickness and number of plies restriction when increasing its number of plies and remedying affixing steel plate reinforcement, can increase substantially the bearing capacity of concrete flexural member, easy anchoring in the time of can utilizing affixing steel plate reinforcement again, by itself and fibre reinforced plastics collaborative work, improved the utilization rate of fibre reinforced plastics, prevented peeling off suddenly of fibre reinforced plastics, thereby improved the bearing capacity of flexural member indirectly, utilize the good ductility of steel plate simultaneously, remedy the deficiency that flexural member ductility reduces when pasting the fibre reinforced plastics reinforcing, improve the stress performance of flexural member.Therefore, utilize above-mentioned two kinds of material composite consolidation concrete flexural members both can increase substantially the bearing capacity of flexural member, can improve rigidity, ductility and globality and the reliability of flexural member again;
2, adopting fibre reinforced plastics and steel plate composite consolidation concrete flexural member is a kind of efficient and economic novel reinforced method, find by experimental study, adopt fibre reinforced plastics and two kinds of material composite consolidations of steel plate concrete flexural member, two kinds of materials not only can well collaborative work, and the mechanical property of concrete flexural member is significantly improved.The utility model not only consolidation effect is good, and can reduce engineering cost greatly, makes engineering investment cost reduce about 40%, therefore is with a wide range of applications.
