Description

Single column pier bridge exempts to build overturning or slip resistance analysis steel structure reinforcing device
Technical field
The utility model belongs to Technology Bridge Strengthening field, particularly relates to a kind of Single column pier bridge and exempts to build overturning or slip resistance analysis steel structure reinforcing device.
Background technology
Single column pier bridge is little to occupy under-clearance, is widely used in interchange place, but due to structure overturning or slip resistance analysis performance own bad, overload Under Eccentric Loading under, overall Cross deformation may be there is thus cause beam body to topple in Single column pier bridge.Increasing the weight of simultaneously along with urban traffic burden, the supporting capacity of bridge also has to be hoisted.
In order to ensure the structural safety of existing Single column pier bridge, the method that prior art is commonly used widens bridge pier in the direction perpendicular to bridge, or increase support column.These methods can improve supporting capacity and the overturning or slip resistance analysis performance of bridge simultaneously, but complicated construction technique, what have also needs concreting of driving piles, and construction also can cause the traffic control of long period, and the road occupying time is long.And urban interchange heavy traffic, require convenient and quick construction, job site floor space is little.In prior art, Chinese patent Single column pier bridge adds steel structure support overturning or slip resistance analysis bracing means 201420603900.0 and gives one conveniently reinforcing technique, can improve the overturning or slip resistance analysis performance of bridge preferably, but can not improve the bearing capacity of bridge.This reinforcing technique still needs concreting, and after building, concrete be waited to reach predetermined strength and just can install bridge pad, the engineering time is long; And according to current prestressing force means of testing, the prestressed loss change in structure cannot Measurement accuracy, and once loss of prestress, cannot reach ideal effect, also add deadweight.
Therefore the rapidly and efficiently Technology Bridge Strengthening developing the busy urban traffic of a kind of energy reply is extremely urgent.
Summary of the invention
The utility model provides a kind of Single column pier bridge to exempt to build overturning or slip resistance analysis steel structure reinforcing device, to solve the deficiency that in above-mentioned background technology, current Single column pier Technology Bridge Strengthening exists.The technical problem that the utility model solves realizes by the following technical solutions: provide a kind of Single column pier bridge to exempt to build overturning or slip resistance analysis steel structure reinforcing device, it is characterized in that: comprise the vertical bolster stake that two are arranged on Single column pier both sides, and be fixed on the linkage for Single column pier and two vertical bolster stakes being linked into an integrated entity on Single column pier; Described vertical bolster stake comprises lower supporting plate, support column monomer, monomer junction plate, supporting studs, hydraulic nut a, upper backup pad, described lower supporting plate is fixed on Single column pier base by chemical anchor bolts, some support column monomers are fixed into an entirety by monomer junction plate by bolt, and are fastened on lower supporting plate by bolt; Described supporting studs is arranged on the top of vertical bolster stake, and is provided with hydraulic nut a thereon, between bridge bottom surface and hydraulic nut a, be provided with upper backup pad; Described linkage comprises fixed head, pre-stressed bolt, hydraulic nut b, junction plate, and described fixed head is connected on Single column pier by chemical anchor bolts; Described pre-stressed bolt matches with hydraulic nut b, is arranged on two relative fixed heads; Described junction plate is for connecting vertical bolster stake and linkage.
Described support column monomer is welded steel structure, and the support column amount of monomer comprised in a vertical supporting post is 1-4.
Centre-height position and the two support column monomer seams of described fixed head installation are contour.
Described junction plate is bolted and fixed head and vertical bolster stake is connected, and junction plate strides across support column monomer seam, is connected with two support column monomers simultaneously.
The beneficial effects of the utility model are:
1. this reinforcing technique adopts modularized design, and each several part assembly all can be prefabricated, only needs overlap joint to assemble at the construction field (site), install very convenient, and each assembly has versatility simultaneously, can adapt to different bearing heights by simply combining from adjustment.
2. this reinforcing technique can improve bearing capacity and the overturning or slip resistance analysis performance of bridge simultaneously, more can adapt to the comprehensive requirement of current bridge strengthening.
3. this reinforcing technique easy construction is quick, and without the need to limiting traffic on bridge during construction, building-site floor space is little, without the need to concreting without the need to Site Welding steel work, has assembled and has got final product onset, and under bridge, the road occupying time is short, can carry out rush repair.
4. braced structures introduces hydraulic nut a, after installation is complete, rotating hydraulic nut a makes upper backup pad contact with bridge bottom surface, connect fluid pressure line to afterwards hydraulic nut a, the prestress application of braced structures is realized by hydraulic coupling, this technology can control the prestressing force in braced structures conveniently by hydraulic control pressure, make stress distribution more reasonable.Hydraulic nut b on fixed head then plays the prestressing force balanced action of fixed head.
