Abstract
The utility model discloses a kind of concrete pontic steel structure reinforcing device, solve existing problem of described pontic being reinforced to operation inconvenience, the technical measures taked: a kind of concrete pontic steel structure reinforcing device, be arranged on pontic and bridge honest between, comprise the girder steel be fixed on for fitting on pontic bottom surface, it is characterized in that, two pieces of support plates that the honest welding edges of bridge has right-angled triangle are stretched at girder steel, these two pieces of support plates are arranged in parallel, support plate one right-angle side welds mutually with girder steel, another right-angle side of support plate is honest towards bridge, another right-angle side of two pieces of support plates is weldingly fixed on by baffle plate together, one end of jack is bearing on baffle plate, the other end act on bridge honest on.
Description
Technical field
The utility model relates to a kind of bracing means, particularly relates to a kind of bracing means for reinforcing concrete pontic.
Background technology
Because concrete pontic has certain application life, after being chronically exposed to the external world, concrete produces because of the erosion of wind and rain and peels off.Concretely peel off the rated load that can reduce pontic, this normal safe that can have influence on pontic passes through.For extending the application life of pontic, and ensureing the safe passing of concrete bridge, using the concrete bridge after certain time limit to need to be reinforced.Existing pontic is fixed that the mode that mainly arranges girder steel on the soffit of pontic realizes, girder steel is fitted along the trend of pontic to be fixed on the soffit of pontic, the two ends of girder steel act on respectively bridge honest on, by girder steel, the support of pontic is improved to the bearing capacity of pontic.But girder steel will play reinforcement effect, must and bridge honest between there is active force, and the length of pontic bottom surface to be slightly less than to the preparation length General Requirements of girder steel, otherwise can not install.And after girder steel is less than the length of pontic, if girder steel can not be applied to bridge honest on, then little to the reinforcement effect of pontic, the bearing capacity of pontic can be reduced on the contrary.Existing to realize girder steel and bridge honest between the transmission of active force, can by wedging mode girder steel end and bridge honest between fill in cushion block, also can be realized by the prestressed mode of mechanical increase.But because girder steel end area is relatively little, no matter be adopt Wedged or mechanical type, operation is got up and is all seemed relatively inconvenient.
Summary of the invention
For overcoming above-mentioned defect, the utility model technical issues that need to address: provide a kind of can the concrete pontic steel structure reinforcing device of convenient working.
For solveing the technical problem, the technical solution of the utility model: a kind of concrete pontic steel structure reinforcing device, be arranged on pontic and bridge honest between, comprise the girder steel be fixed on for fitting on pontic bottom surface, it is characterized in that, two pieces of support plates that the honest welding edges of bridge has right-angled triangle are stretched at girder steel, these two pieces of support plates are arranged in parallel, support plate one right-angle side welds mutually with girder steel, another right-angle side of support plate is honest towards bridge, and another right-angle side of two pieces of support plates is weldingly fixed on by baffle plate together; One end of jack is bearing on baffle plate, the other end act on bridge honest on.The effect of jack is that girder steel is fully fitted on the bottom surface of pontic, and makes girder steel produce certain prestressing force, and can adapt to the bracing reinforcement to pontic.
Earnestly and between the other end of jack be provided with bearing at bridge, bearing has the dividing plate being parallel to baffle plate, the other end of jack is bearing on dividing plate.So that the support of jack, the honest bottom surface structure of bridge can be adapted to well by arranging bearing.
Bearing comprises trough-shaped body, and two side plates of trough-shaped body are triangular in shape, and the base plate laminating of trough-shaped body is fixed on the honest surface of bridge, and described dividing plate is welded on two side plates.This trough-shaped body can adapt to the support requirement of arch pontic well.
Described trough-shaped body be fixed on by many expansion bolts bridge honest on.What the structure of trough-shaped body can adapt to expansion bolt well arranges requirement.
Described girder steel is channel-section steel, and girder steel is fixed on the soffit of pontic by many chemical bolts.Chemical bolt had both ensured that the laminating between girder steel and pontic soffit was fixed, and can adapt to again the prestressed applying of jack pair girder steel.
Compared with prior art, the beneficial effect that the utility model has: owing to arranging described baffle plate in the end of girder steel, this facilitates the support needs to jack one end well.In addition, by arranging jack, structure is simple, is convenient to, for girder steel Shi Hanzhang, girder steel be fitted on the bottom surface of pontic well, is convenient to for pontic provides stable support.
Accompanying drawing explanation
Fig. 1 is the local structural graph of this concrete pontic strengthening of steel bridge device.
Detailed description of the invention
See in figure, this concrete pontic steel structure reinforcing device is arranged between pontic 3 and bridge honest 1, and agent structure is girder steel 5, and girder steel 5 laminating is fixed on the bottom surface of pontic 3.Stretch between the end of bridge honest 1 and bridge honest 1 at girder steel 5 and be provided with jack 7, on this end that the two ends of jack 7 act on girder steel 5 respectively and bridge honest 1, by the effect of jack 7 to girder steel 5 Shi Hanzhang, girder steel 5 is made to adapt to the trend of pontic 3 and fit together with the bottom surface of pontic 3.Girder steel 5 is channel-section steel, and girder steel 5 is fixed on the bottom surface of pontic 3 by many chemical bolts 4.
The end stretching to bridge honest 1 at girder steel 5 is provided with two pieces of support plates 6, and support plate 6 is right-angled triangle, and a right-angle side in support plate 6 and girder steel 5 weld together, and another right-angle side of support plate 6 is towards bridge honest 1, and two pieces of support plates 6 are arranged in parallel.Another right-angle side of two pieces of support plates 6 links together by baffle plate is soldered, and an end of jack 7 is directly bearing on baffle plate.
The external surface of bridge honest 1 is fixed with bearing 8, and bearing 8 is trough-shaped body, and bearing 8 is fixed on bridge honest 1 by many expansion bolts 2.Bearing 8 is made up of two side plates be connected as a single entity and a base plate, and the surface laminating of base plate and bridge honest 1, expansion bolt 2 is connected in bridge honest 1 through base plate, and two blocks of side plates stretch out towards an end of girder steel 5.Two blocks of side plates are welded with one piece of dividing plate, and the leg-of-mutton shape of side plate makes dividing plate parallel with above-mentioned baffle plate, and the other end of jack 7 is bearing on dividing plate.
