Description
Technical field
The utility model belongs to technical field of building construction, is specifically related to a kind of heavy type truss formula crane girder.
Background technology
There is the industrial premises of weight-hauling equipment at present, generally all can be provided with the crane girder supporting with weight-hauling equipment in factory building, in order to bear the weight of weight-hauling equipment itself and hoisting heavy, and by this crane girder, above-mentioned load is passed to factory building force column and column footing.Common crane girder mainly contains Reinforced Concrete Crane Girder, prestressed reinforced concrete crane girder and ANALYSIS FOR STEEL CRANE GIRDERS, and wherein steel crane beam is based on Welder's shaped steel steel flanged beam crane girder, namely becomes I-shaped crane beam by three block plate Combination Welding.This kind of crane girder is large because of bearing capacity, needs large scale steel plate, and needs to weld many stiffeners at section bar belly, to gain in strength and rigidity.Therefore its steel using amount is more, the relative sole of stock utilization is insoluble problem in the industry always.In addition, because welding stiffener is more, manufacture craft is more complicated, and processing request is also higher, and welding job amount is many, and weldment is yielding, and productive costs is higher, and trajectory accuracy is difficult to ensure.
Summary of the invention
The purpose of this utility model is for the problems referred to above, a kind of heavy type truss formula crane girder is provided, Problems existing in effective solution existing i shaped steel steel flanged beam crane girder, while ensureing load bearing requirements, saving steel greatly, reduce welding job amount, simplify production technology, improve component precision and reduce productive costs.And increase stability and the stress balance of whole crane beam, distortion and distortion are less likely to occur, effectively increase the service life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of heavy type truss formula crane girder, comprise two i-shape steel beams be parallel to each other, the two ends of described two i-shape steel beams are individually fixed on force column, the close two ends place of described two i-shape steel beams is fixedly connected with respectively by pipe link, base plate is provided with below described two i-shape steel beams, described two i-shape steel beams are symmetricly set in base plate both sides, described two are connected by spaced diagonal web member between i-shape steel beam with base plate, and described base plate two ends are provided with reinforced company's contact pin.
Compared with prior art, the utility model adopts the i-shape steel beam of two settings parallel to each other, and sets up the base plate of thickening in below, three forms firm triangular structure, crane girder is stressed more even, and is not easy to deform and distortion, effectively extends the service life of crane girder.Be connected by diagonal web member between i-shape steel beam with base plate, instead of web of the prior art, also do not need to increase stiffener again, greatly save steel structure consumption, reduce welding job amount, simplify production technology, improve component precision and reduce productive costs.Base plate two ends arrange reinforced company's contact pin, for fixing with force column, can increase Joint strenght and the rigidity of i-shape steel beam, effectively sharing load-bearing load, ensure load bearing requirements.
As preferably, the thickness of described base plate is 200 ~ 300mm.
As preferably, described base plate both sides are respectively equipped with raised line, and described raised line extends on floor length direction.Base plate increases raised line, and make base plate cross-sectional plane form spill, raised line can support diagonal web member, strengthens the firmness of structure.
As preferably, between described pipe link and base plate, be provided with vertical rod.Increase the firmness on vertical direction.
As preferably, described reinforced company contact pin cross-sectional plane is butterfly.Strengthen connecting strength and stiffness.
The utility model discloses a kind of heavy type truss formula crane girder, effectively solve Problems existing in existing i shaped steel steel flanged beam crane girder, while ensureing load bearing requirements, saving steel greatly, reduce welding job amount, simplify production technology, improve component precision and reduce productive costs.And increase stability and the stress balance of whole crane beam, distortion and distortion are less likely to occur, effectively increase the service life.To have a good application prospect in technical field of building construction.
