Abstract
The utility model discloses a door type steel frame structure, which consists of a first supporting leg, a second supporting leg, a cross beam and an upper beam, the first and the second supporting legs are oppositely arranged and fixed on the ground, the cross beam is welded between the first and the second supporting legs, and the upper beam is welded on the top ends of the first and the second supporting legs. The fabrication cost of the door type steel frame structure is reduced, and the structure is simple.
Description
Technical field
The utility model relates to a kind of steel frame construction, particularly a kind of portal frame structure.
Background technology
In recent years, (such as Standard Factory Room) adopted steel plate or steel bar to construct in building field, but its complex structure, intensity is bad, and cost remains high and has had a strong impact on the uses of steel work in building field such as steel plate or steel bar.
The utility model content
Technical problem to be solved in the utility model provides a kind of portal frame structure, and it is simple in structure and reduce cost.
For solveing the technical problem, the utility model provides a kind of portal frame structure, it is characterized in that, it comprises first leg, second leg, crossbeam and upper beam, first leg and second leg are oppositely arranged and fix on the ground, crossbeam is welded between first leg and second leg, puts the beams in place to be welded on the top of first leg and second leg.
Preferably, described upper beam is shaped as arc.
Preferably, described first leg and second leg be shaped as tubulose, crossbeam be shaped as strip.
Positive progressive effect of the present utility model is: the utility model portal frame structure reduces manufacturing cost, and is simple in structure, the safety that can improve building.
Description of drawings
Fig. 1 is the structural representation of the utility model portal frame structure.
The specific embodiment
Lift a preferred embodiment below, and come the clearer the utility model that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model portal frame structure comprises first leg 1, second leg 2, crossbeam 3 and puts the beams in place 4, first leg 1 and second leg 2 are oppositely arranged and fix on the ground, crossbeam 3 is welded between first leg 1 and second leg 2, and upper beam 4 is welded on the top of first leg 1 and second leg 2.Put the beams in place 4 the arc that is shaped as, described first leg 1 and second leg 2 be shaped as tubulose, crossbeam 3 be shaped as strip.The utility model portal frame structure only needs four elements, can reduce manufacturing cost, and is simple in structure, the safety that can improve building.
First leg 1, second leg 2, crossbeam 3 and 4 the material of putting the beams in place are Q690E type high strength steel, and the yield strength of Q690E type high strength steel is more than or equal to 690Mpa, and tensile strength is 770-940Mpa.Because the intensity and the hardness of Q690E type high strength steel are higher, are using Q690E type high strength steel in super large floating crane and the shipbuilding on a large scale, and the not competent use in engineering of traditional low-alloy steel.This Q690E type high strength steel is made by applicant company, by opening bar, mill the limit, pre-bending, bending, moulding, joint close prewelding, interior weldering, outside weld, pipe end processing, aligning, finishing, repairing steps such as end and final detection and finish, have flawless and advantages of high strength, can improve the intensity and the safety of building.
Though more than described the specific embodiment of the present utility model, but those skilled in the art is to be understood that, these only illustrate, and under the prerequisite that does not deviate from principle of the present utility model and essence, can make numerous variations or modification to these embodiments.Therefore, protection domain of the present utility model is limited by appended claims.
Claims (3)
