Description
Technical field
The utility model relates to Highway Municipal building technology field, refers to a kind of for the syndeton of FRP pipe concrete arch ring with basis particularly.
Background technology
Arch bridge, as the one of traditional bridge type, has that span ability is strong, an advantage such as simple structure, stressed clear and definite, good looking appearance, is subject to the favor of construction industry always.But arch bridge also has its himself defect, as deadweight is comparatively large, high to ground conditional request, working procedure is complicated.
Along with the development of design and construction technology, as the arch ring of arch bridge main bearing member, its material obtains improvement on the basis of traditional masonry arch bridge, emerge much new arch ring form, such as steel arch bridge, reinforced concrete arch bridge, concrete filled steel tube combination arch bridge, steel reinforced concrete combination arch bridge etc., improve span ability and the landform adaptive capacity of arch bridge further.
It is a kind of deck type structure that FRP pipe concrete combines embed-type arch bridge, and its main primary structure member is FRP pipe concrete arch ring, by core concrete with wrap up in FRP pipe outward and form.FRP material has from heavy and light, intensity is high, good endurance, workability are good feature, and the effect of contraction of FRP tube wall to its inside fill concrete makes concrete be in three dimension stress state, reduces longitudinal cracking during concrete compression, improves compressive strength; And the concrete of inside can prevent FRP pipe generation cripling effectively, strengthen the geometrical stability of FRP pipe, improve integral rigidity.FRP pipe concrete arch ring, based on pressurized, can give full play to the advantage of bi-material, avoid deficiency, thus makes the bearing capacity of combination arch ring much larger than the core concrete of composition arch ring and wrap up in FRP pipe bearing capacity sum outward, improves the span ability of bridge.
FRP pipe concrete combines embed-type arch bridge under the effect of vertical load, and arch ring is based on pressurized, and arch springing place not only produces vertical counter-force, also will produce horizontal thrust, and therefore arch ring is stressed key point with the junction on basis.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of for the syndeton of FRP pipe concrete arch ring with basis, improves arch ring and basic switching performance.
The technical solution of the utility model is: a kind of for the syndeton of FRP pipe concrete arch ring with basis, it comprises arch ring body and base matrix, the arch springing of described arch ring body is arranged in described base matrix, it is characterized in that: described arch springing is fixedly connected with described base matrix by reinforcing cage, described reinforcing cage comprises the many longitudinal reinforcements be arranged in parallel and a spiral stirrup, one end of described longitudinal reinforcement is arranged in described arch springing, the other end of described longitudinal reinforcement extend in base matrix, the end that described longitudinal reinforcement stretches into base matrix is outwards bent to form hook solid, described many longitudinal reinforcements are connected and fixed by a spiral stirrup.
Preferably, between outermost longitudinal reinforcement and arch ring inner body wall, several cushion blocks are provided with.
Preferably, described arch ring body is made up of FRP material, is filled with concrete in described arch ring body.
The utility model is connected with base matrix by the arch springing of reinforcing cage by arch ring body, the end that the longitudinal reinforcement of reinforcing cage stretches into base matrix is outwards bent to form hook solid, longitudinal reinforcement with crotch enhances the anchoring property of arch ring body and base matrix, effectively can resist the various internal force at arch springing place, improve the switching performance of the two.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic cross-section of Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to figure 1 and Fig. 2, the present embodiment a kind of for FRP pipe concrete arch ring with basis syndeton, it comprises arch ring body 1 and base matrix 2, and the tube wall of arch ring body 1 is made up of FRP material, concrete is filled with, to strengthen intensity and the bearing capacity of arch ring body 1 in arch ring body 1.The arch springing of the arch ring body 1 of the present embodiment is arranged in base matrix 2, arch springing is fixedly connected with base matrix 2 by reinforcing cage, reinforcing cage comprises the many longitudinal reinforcements be arranged in parallel 3 and a spiral stirrup 4, one end of longitudinal reinforcement 3 is arranged in arch springing, the other end of longitudinal reinforcement 3 extend in base matrix 2, and the end that longitudinal reinforcement 3 stretches into base matrix 2 is outwards bent to form hook solid; Many longitudinal reinforcements 3 carry out the connection of self by a spiral stirrup 4 and fix.
The arch springing of arch ring body 1 is connected with base matrix 2 by reinforcing cage by the present embodiment, the end that the longitudinal reinforcement 3 of reinforcing cage stretches into base matrix 2 is outwards bent to form hook solid, longitudinal reinforcement 3 with crotch enhances the anchoring property of arch ring body 1 and base matrix 2, effectively can resist the various internal force at arch springing place, improve the switching performance of the two.
Between outermost longitudinal reinforcement 3 and arch ring body 1 inwall, be provided with several cushion blocks 5, to ensure the thickness of arch ring body 1 inner concrete topping, avoid reinforcing bar directly to contact arch ring body.
The longitudinal reinforcement 3, spiral stirrup 4, cushion block 5 etc. of the present embodiment in factory or site prefabrication assembling, directly can be installed during use, shorten construction period.
The present embodiment is flexible and changeable, is applicable to the combination arch ring of circle, the various shape such as square.
The above is only preferred embodiment of the present utility model, not does any pro forma restriction to structure of the present utility model.Every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of the technical solution of the utility model.
