Description
Technical field
The utility model is related to a kind of concrete structure and falls beam joist device, more particularly to falls beam pre-structure in place
Between thing headroom it is not enough, can not normal construction when the joist device that uses, belong to technical field of bridge construction.
Background technology
Bridge falls beam construction and is widely used in all kinds of engineerings such as railway, highway, municipal administration.(or constructed in concrete structure
Thing) prestressed structure fall that beam is in place or works side position applies and moves beam work progress in place after tensioning using upper pour
In, it will usually because headroom is not enough between up-down structure thing or other reasonses lead to not normal in place, the safety and matter of influence engineering
Amount.Particularly realize that bridge is in place bridging equipment (such as Bridge Erector, large-scale hoisting machinery) can not be used, and scene is not
Satisfy the requirements concrete structure (or the structures) for realizing cast-in-situ shaping when, or in existing bridge or similar structures body
When maintaining (such as bearing replacement), construction operation difficulty is big, and security risk is high, and construction quality is difficult to ensure.
The content of the invention
For the above-mentioned problems in the prior art, the utility model provides a kind of be used in headroom deficiency, construction
Concrete structure under the conditions of working space is narrow and small falls beam joist device, using its construction safety, efficiently.
The utility model solves the technical scheme that its technical problem used：One kind is used to fall under the conditions of beam headroom deficiency
Concrete structure fall beam joist device, it is characterized in that：It is included outside the corbel of the shape of a saddle, the both sides of the corbel
Side is fixedly installed the top plate of one piece of jacking load respectively, and the top of every piece of top plate is equipped with stiffened steel plates and the top
The sidepiece of plate and corbel is fixedly connected.
Joist device in the utility model is when in use to hold up concrete structure and provide the jackings such as jack
The hard point of equipment, wherein, corbel is used to hold up concrete structure when in use, and the top plate of both sides is held as jack jacking
The fulcrum of power.Stiffened steel plates are used for the intensity of Strengthening Roof.
The beneficial effects of the utility model are：The utility model is simple in construction, easy to operate, construction safety, efficiency of construction
It is high.The utility model is by special structure design, under conditions of headroom is not enough, can be by setting this in structure bottom
Utility model, holds up works using the utility model and provides the Lifting Equipment hard point such as jack, by changing jack
Position of the fulcrum, fulcrum is moved to the both sides of joist device by the bottom of works so that jack working space becomes big,
Ensure that can continue to progress in the case where headroom is not enough falls beam operation.The utility model can effectively solve headroom deficiency etc. and be limited
Under the conditions of works fall beam problem in place, be particularly suitable for use in newly-built structure thing it is upper it is cast-in-place, to fall beam in place, or existing bridge
Jacking when maintenance Deng similar structures thing, bearing replacement and fall beam operation, its resource input is few, easy to operate, method
It is practical, it is easy to draw materials, it can be ensured that engineering construction safety and quality.

Embodiment
The utility model is further described below by specific embodiment and with reference to accompanying drawing：
As shown in drawings, it is a kind of be used to fall beam headroom it is not enough under the conditions of concrete structure fall beam joist device, its
Corbel 1 including the shape of a saddle, it is made by steel plate, and the outside of the both sides of the corbel 1 is fixedly installed one piece respectively
The top plate 2 of jacking load, the top of every piece of top plate 2 is equipped with stiffened steel plates 3 and the top plate 2 and the sidepiece of corbel 1
It is fixedly connected.To ensure the bulk strength of device, corbel 1, top plate 2, stiffened steel plates 3 should have enough intensity and thickness, plus
Strength steel plate 3 should firmly be welded with top plate 2 and corbel 1.
The method that box beam falls beam construction is carried out using above-mentioned joist device：First fall beam construction method according to routine and utilize thousand
Jin top 6 sets fulcrum in the bottom of box beam 4 and box beam is fallen to beam to after certain altitude, because the not enough jack of headroom can not normal operation
When, then the joist device 5 is installed in the corresponding position in bottom of box beam 4, and ensure the beam bottom and the inner side of corbel 1 of box beam 4
Face is in close contact, and the former position of the fulcrum positioned at beam bottom is changed at the ceiling location of joist device 5, using sleeper at box beam bottom
Portion is good by box beam pad, and then the jack by original position in beam bottom is moved to the position of top plate 2 of the both sides of joist device, and top plate is made
For the new fulcrum of jack, it is ready after start jack operation, proceed to fall beam operation until box beam is dropped down onto both
Positioning is put, and is located on mounted bearing.
Other parts in the present embodiment use known technology, will not be repeated here.
The works that the utility model can be solved effectively under the confined conditions such as headroom deficiency falls beam problem in place, operation letter
Singly, conveniently, construction safety, it can be ensured that engineering construction safety and quality.
