Description
Technical field
The utility model relates to a kind of Coping Construction support system, particularly a kind of steel diagonal brace for pier prestressed cap beam with extra length Construction Supporting System in water.
Background technology
At present, domestic heavy civil, Design of Highway Bridge mostly are two-way six-lane or eight tracks, unidirectional three lanes or Four-Lane Road, and the length of pier stud bent cap is most at below 40m, minority length is at more than 40m, and Coping Construction generally adopts Support Method and no rack technique two kinds of modes.The requirement for bearing capacity of Support Method to ground is high, and costly, the duration is limited for basement process, constructs careless slightly, can cause support integral sinking, has a strong impact on the construction quality of bent cap, and inapplicable for bridge pier in water; No rack technique construction common are: pre-buried method, cross method and Hold Hoop method, although be applicable to bent cap in high pier capping beam and water, but three kinds of methods cut both ways, the advantage of often kind of method all can not be taken into account and ensure that bent cap support system is to many-sided overall control overflow such as construction speed, quality and costs.
Industry park, Zhong Huan through street, Suzhou City section engineering Wusongjiang River bridge, for single span double width Simple Supported Steel Truss Bridge, gross weight is about 4410t, across footpath 119m, the wide 22.8m of single width, belong to domestic single width width, Suzhou City and Jiangsu Province across footpath, bent cap: long 54.2m, wide 3.6m, high 2.5m, also be domestic bridge length of the same type, single bent cap gross weight can reach 1300t, under bent cap, between pier stud and pier stud, clear distance is 20.2m, and be positioned at over-water construction, there is the silt soil strata dark more than 20m in the south of the River, Wusong bank, traditional construction with brackets and no rack technique construction are not all suitable for this engineering.Meanwhile, this engineering is very high to the supporting capacity of support, stability requirement.
Summary of the invention
The utility model provides a kind of steel diagonal brace for pier prestressed cap beam with extra length Construction Supporting System in water for solving in known technology the technical problem that exists, this steel diagonal brace can be worked in coordination with steel pipe post and be supported pier prestressed cap beam with extra length Construction Supporting System in water, and make this support system have stronger supporting capacity and higher stability, can be greater than 8m more than 40m, setting height(from bottom) by prove-in length, between pier shaft, clear distance is greater than pier capping beam construction in the overlength water of 18m.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is: a kind of steel diagonal brace for pier prestressed cap beam with extra length Construction Supporting System in water, this steel diagonal brace is provided with two and is parallel to each other and isometric relative strut, two described struts by steel structure connection together, pin hinge and bearing thereof is connected with in the bottom of each described strut, pin hinged-support is connected with the cushion cap of pier stud in water by pre-embedded steel slab, bottom and the described pin hinged-support of described strut pass through pin hinge connection, the afterbody cut with scissors at described pin is provided with annular groove, axial limiting baffle plate is fitted with in described annular groove, described axial limiting baffle plate is fixed on described pin hinged-support, described in every root, the top of strut is provided with horizontal support cover plate.
Described strut adopts Two bors d's oeuveres i-beam structure.
At the position of Two bors d's oeuveres i iron strut and described pin hinge connection, the web both sides of described Two bors d's oeuveres i iron strut are equipped with reinforcement steel plate.
Two described struts by M shape steel structure connection together.
The advantage that the utility model has and good effect are: in water pier stud bearing platform construction during pre-embedded steel slab, after in water, pier stud has been constructed, steel diagonal brace is connected on pre-embedded steel slab, pull out the Larsen stake for pier stud construction in cushion cap and water, steel diagonal brace is forwarded to setting inclination angle, next step construction can be carried out, the installation period of bent cap support system can be shortened, save cost.Reason is: utilize pin hinge structure, make steel diagonal brace carry out angle adjustment.Because the Larsen stake of pier stud working cofferdam and the steel diagonal brace of support intersect, the Larsen stake of crossover sites during mounting bracket, first must be extracted.If adopt the erection mode that steel diagonal brace directly welds with cushion cap pre-embedded steel slab, difficulty of construction is large, cushion cap Lijiang River bank far, again has underwater obstacle, therefore change into and increase an articulated structure at the footing place of steel diagonal brace and be connected with cushion cap pre-embedded steel slab, use the impact that this articulated structure can not intersect by field environmental condition and Larsen stake, after steel diagonal brace is connected with cushion cap pre-embedded steel slab, first upright and steel pipe post is connected and fixed, and installs after Larsen stake is pulled out according to oblique angle again.If do not arranged pin hinge turntable, then need entirety to set Larsen pile cofferdam, all pier stud cushion caps are formed closed entirety.Swivel point is set, the stake of part bearing platform construction Larsen can be pulled out in advance, decrease cost and duration that entirety sets Larsen stake simultaneously, shorten the support installing time, save the lease expenses of Larsen stake.The utility model utilizes existing cushion cap as the basis of structure, decreases the process procedure of basement process, and structure steel beam column used can also recycle, and can save great amount of cost.The support system of the utility model construction is adopted to compare with no rack technique with traditional Support Method, construction with brackets can be avoided to process ground or to set steel pipe pile, the shortcoming of bearing capacity and stability deficiency, and the utility model adopts shaped steel supporting, rigidity is large, supporting capacity is strong, relative no rack technique construction bent cap, avoid pre-buried method, cross method, every defect of Hold Hoop method, on permanent structure pier shaft quality and outward appearance without impact, can prove-in length more than 40m, setting height(from bottom) is greater than 8m, between pier shaft, clear distance is greater than pier capping beam construction in the overlength water of 18m, and the Coping Construction of non-cylindrical pier stud can be applicable to.
In sum, the utility model rigidity is large, and supporting capacity is strong, can the reduction of erection time, reduce labour cost and material cost, and reusable edible, can be greater than 8m more than 40m, setting height(from bottom) by prove-in length, between pier shaft, clear distance is greater than pier overlength Coping Construction support system in the water of 18m.
