Abstract
The utility mode relates to a steel pipe arched bridge closure connecting device, solved that current steel pipe arched bridge closure exists that precision internal force is not up to standard, during the operating cost difficultly and the lower problem of factor of safety. All be provided with flange in the steel pipe arched bridge port, every flange all includes the backing plate, and the center of backing plate is fixed with interior bushing pipe, and is provided with the stiffening rib that uses its center to distribute as centre of a circle equipartition and fix with interior bushing pipe and steel pipe arched bridge on the backing plate, be provided with adjusting nut between two backing plates, the dextrorotation screw rod that has the left -handed screw of fixing with the left side backing plate and contact is twisted with the right side backing plate at both ends about adjusting nut, the inboard of two backing plates all is fixed with the stiffener. The utility model has the advantages of reasonable design reliably, convenient quick realization the instantaneous closure of steel pipe arched bridge, precision, internal force are all up to standard moreover, have stopped the emergence of potential safety hazard, have simple structure, processing is convenient and advantage with low costs.
Description
Technical field
The utility model relates to steel pipe arch bridge closure construction equipment, is specially a kind of steel pipe arch bridge closure linkage.
Background technology
Along with the raising of expanding economy, environmental requirement, when crossing over great river, great river, deep valley, Long Span Railway steel pipe arch bridge obtains increasing application.Railway transportation load is heavy, vibration is large, railway steel tube arch is had higher requirement, in the installation of free cantilever erection, huge structure, long-span Steel Arch sections that weight is overweight, linear, the Internal force control of particularly steel pipe arch bridge closure must become the key of steel pipe arch bridge success or failure.
The mode that current domestic tubular arch closure adopts common built-in gad joint or minimum temperature directly to weld usually is to complete the instantaneous closure of tubular arch.These two kinds of methods not only cannot meet the requirement that the linear precision of free cantilever erection large diameter steel pipe arch bridge is high, internal force is large, and the operating time is long, need use lot of materials, equipment and labour, and complex process operation is not convenient, and safety factor is low.
Summary of the invention
In order to solve the closure of existing steel pipe arch bridge, the utility model exists that precision internal force is not up to standard, operation is wasted time and energy and the lower problem of safety factor, provide a kind of steel pipe arch bridge closure linkage.
The utility model adopts following technical scheme to realize: steel pipe arch bridge closure linkage, comprise about two adjacent steel pipe arch bridges, adpting flange is provided with in steel pipe arch bridge port, each adpting flange includes backing plate, the center of backing plate is fixed with internal lining pipe, and backing plate is provided with its center for the uniform distribution in the center of circle and the stiffening rib fixing with internal lining pipe and steel pipe arch bridge; Be provided with adjusting nut between two backing plates, the two ends, left and right of adjusting nut are screwed with the left-handed screw fixed with left side backing plate and the right handed screw with right side pad contact; The inner side of two backing plates is all fixed with stiffener.
When carrying out steel pipe arch bridge closure opertation, adpting flange is welded on steel pipe arch bridge inwall in advance, left-handed screw one end is welded with left side backing plate, rotating adjusting nut, right handed screw is extended until hold out against with right side backing plate, by adjusting nut adjustment closure mouth size, reach after designing requirement until environment temperature, weld right handed screw and right side backing plate immediately, complete instantaneous closure, overcome the closure of existing steel pipe arch bridge and have that precision internal force is not up to standard, operation is wasted time and energy and the lower problem of safety factor.
The utility model reasonable in design is reliable, achieves the instantaneous closure of steel pipe arch bridge easily and fast, and precision, internal force are all up to standard, have stopped the generation of potential safety hazard, has simple, the easy to process and advantage that cost is low of structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-steel pipe arch bridge, 2-backing plate, 3-internal lining pipe, 4-stiffening rib, 5-adjusting nut, 6-left-handed screw, 7-right handed screw, 8-stiffener.
Detailed description of the invention
Steel pipe arch bridge closure linkage, comprise about two adjacent steel pipe arch bridges 1, adpting flange is provided with in steel pipe arch bridge 1 port, each adpting flange includes backing plate 2, the center of backing plate 2 is fixed with internal lining pipe 3, and backing plate 2 is provided with its center for the uniform distribution in the center of circle and with internal lining pipe 3 and the fixing stiffening rib 4 of steel pipe arch bridge 1; Be provided with adjusting nut 5 between two backing plates 2, the two ends, left and right of adjusting nut 5 are screwed with the left-handed screw 6 fixed with left side backing plate 2 and the right handed screw 7 contacted with right side backing plate 2; The inner side of two backing plates 2 is all fixed with stiffener 8.
In specific implementation process, arch rib adopts cable crane integral hoisting, the symmetrical free cantilever erection in two sides, and stayed knotting method is installed, and arch rib middle part is stayed and established closure section; After free cantilever erection completes, accurate adjustment arc rib alignment, joins according to actual measurement closure mouth size and cuts adjusting nut 5 and install adpting flange, complete instantaneous closure at closure temperature.
