Abstract
The invention discloses a simple-supported continuous construction method and a structure thereof. The construction method comprises the following steps of pouring a bridge pier and arranging a mounting support on the top of the bridge pier; lifting a precast reversed T-shaped capping beam to the mounting support; lifting and arranging small box girders on the wing plate of the precast reversed T-shaped capping beam to form a simple-supported state; pouring concrete to clearances between the web plate of the precast reversed T-shaped capping beam and the small box girders on the two sides to form wet joints, and penetrating and tensioning of hogging moment steel bundles between the upper portion of the web plate and the top plates of the small box girders on the two sides are completed at the same time. The simple-supported continuous structure is formed through the construction method. The simple-supported continuous construction method and the structure thereof have the advantages of common simple-supported continuous structures of being reliable, good in durability and the like, bridge landscapes can be further improved, the structural height between a bridge floor and the bottom of the capping beam is reduced greatly, net space under a bridge is saved, construction procedures are simplified, and a construction cycle is shortened.
Description
Technical field
The present invention relates to the technical field of bridge construction and construction, relate in particular to a kind of freely-supported and become continuous construction method and structure thereof.
Background technology
The continuous simple beam structure system of bridge floor due to exist bridge floor easily the shortcoming such as cracking and with the competition of beam structure system in usually at a disadvantage.Simultaneously because the construction complexity of cast-in-situ concrete continuous beam is loaded down with trivial details, people wish the batch Prefabrication of simply supported beam and the superior function of continuous beam to combine always, accelerate the construction speed of continuous beam by the mode of beam or plate batch Prefabrication, to save a loaded down with trivial details die process, produced thus by whole prefabricated across beam slab, set up after in place and make it continuous " after first freely-supported continuously " construction method at end concreting stretch-draw prestressing force, the system forming is called as " continuous structure system after first freely-supported ".At present, the bridge that freely-supported becomes the continuous form of structure porous Medium Span in high-grade highway (particularly speedway) bridge accounts for very large proportion.
Comprehensive bridge floor continuously and structure freely-supported become continuous two kinds of structural systems, the contrast situation of its scheme quality is as shown in the table:
As can be seen from the above table, freely-supported becomes continuous structural system except being slightly inferior to aspect speed of application and construction costs the continuous scheme of bridge floor, and other rigidity in structure, durability, Bridge Landscape, engineering application aspect are all better than the continuous scheme of bridge floor.Bridge on speedway, and be the more section of heavy vehicle, this has higher requirement to the aspect such as reliability of structure, durability.In sum, little case beam freely-supported change is better structural concept continuously.
After the construction process of common freely-supported change continuous structure is generally first freely-supported, Continuous Bridge is constructed, and its idiographic flow is as follows:
1. the prefabricated employing batch production of girder is produced, when beam slab concrete strength reach design strength 100% after, carry out the prestress wire stretch-draw of positive bending moment district, after stretch-draw finishes, carry out hole path pressure grouting.
2. before the steel strand tension of hogging moment area, temporary support is set, beam slab is arranged on temporary support by hole, make it to become simply-supported state, simultaneously by permanent bearing installation in position.
3. jointing section reinforcing bar, arranges joint steel bundle bellows and steel strand is through in bellows, at day concreting when temperature≤15 DEG C.Until concrete intensity reach design strength 100% time, stretch-draw hogging moment area twisted wire mud jacking.
4. temporary support is removed, completed by freely-supported and change to continuous system.
The freely-supported forming according to above-mentioned flow process construction becomes continuous structure tool and has the following advantages:
1. have rigidity large, be out of shape the advantages such as little, shrinkage joint is few and it is comfortable to drive a vehicle, the good endurance of structure.
2. the prestressed strand of simply supported beam carries out stretch-draw in factory, and the prestressed strand of hogging moment area is arranged and stretch-draw is all carried out on girder, only needs hanging device lifting girder, has reduced construction equipment, can avoid again the ground obstacle of stretch-draw prestressing force steel Shu Zaocheng.
3. precast beam can adopt standardized structural element, carries out batch production and unifies production and administration, is conducive to technical operation, has saved the engineering time, the reduction of erection time, increases economic efficiency.
The little case beam freely-supported of application at present becomes continuous structure system has obvious advantage in the rigidity of structure, durability, engineering application aspect, but also has the problem that bent cap height is excessive, construction period is relatively grown.Conventional freely-supported becomes continuous structure and still has following weak point:
1. the larger bent cap of the essential design scale of construction, if adopt rectangle bent cap, bent cap height approximately reaches 3.8m as calculated, for meeting under-clearance, this scheme requires floor elevation to promote about 2m; And bent cap is clumsy, sense of depression is strong, and landscape effect is very poor.
2. generally will carry out the system conversion of bearing, construction is trouble comparatively.
3. the reinforcing bar binding of crossbeam and the workload of concreting are larger, can cause the prolongation of duration.
4. also separately have a kind of Dun Ding without bent cap, prefabricated small box girder is first supported on falsework, waits to have built crossbeam (the dividing into bearing) method of striking more afterwards.But it is high that this engineering method support stability requires, and falsework is built and demolition expense expenses of labour material; More difficult when continuous beam falls frame, safety is relatively poor, easily brings potential safety hazard, and for the section that has heavy traffic under bridge, setting up of support also can have a strong impact on traffic.
Therefore, become continuous construction method and structure thereof for current freely-supported, be also necessary to carry out Improvement in the hope of further optimization.Those skilled in the art is devoted to develop a kind of freely-supported always and becomes continuous construction method and structure thereof, can overcome above-mentioned deficiency, not only there is the advantage such as reliable in structure, good endurance that common freely-supported becomes continuous structure, can also improve Bridge Landscape, structure height at the bottom of greatly reducing from bridge floor to bent cap, save under-clearance, simplify construction sequence, shorten construction period.
Summary of the invention
Because above-mentioned the deficiencies in the prior art, the present invention proposes a kind of advantage such as reliable in structure, good endurance with common freely-supported change continuous structure, can also improve Bridge Landscape, structure height at the bottom of greatly reducing from bridge floor to bent cap, save under-clearance, simplify construction sequence, the freely-supported that shortens construction period becomes continuous construction method and structure thereof.
