Abstract
The invention relates to a lightweight U-shaped steel beam structure which belongs to the technical field of steel structure building members. The adopted technical scheme is as follows: U-shaped steel beam lateral plate edges are symmetrically arranged in the two side directions of a U-shaped steel beam baseplate; punching a row of equilateral triangle-shaped through holes at the middle of each U-shaped steel beam lateral plate edge; and the equilateral triangle-shaped through holes are in positive-reverse arrangement alternately, a hem which is folded to the same side is arranged at a mouth part of each equilateral triangle-shaped through hole, and a long strip-shaped convex rib which is opposite to the direction of the hem is punched between every two equilateral triangle-shaped through holes. The U-shaped steel beam structure can not only reduce the weight of a steel beam, but also increase the loading capacity of the steel beam, be conductive to safety of a building and reduce the construction cost of the building.
Description
Technical field
The present invention relates to a kind of structure of U font girder steel, belong to steel building component technology field.
Background technology
U font girder steel is widely used a kind of structural member on the steel building, and its main effect in building unit is the support crossbeam as the steel building roofing, and can be found out by its role: it mainly bears flexural stress.
At present; Be well known that: the structure of U font girder steel all is the structure of real abdomen; Because the flexural stress that U font girder steel bears, can know according to mechanical properties of materials: flexural stress mainly acts on the both sides up and down of girder steel side plate, and the moment of flexure that material bore at the position that mediates is zero or very little; So, still not a kind of waste of the material of the U section steel beam mid portion of real fu jie structure; Simultaneously.Its existence also can increase building weight, is unfavorable for practicing thrift cost; Simultaneously, also can make the security performance of building receive influence to a certain degree.
Summary of the invention
The objective of the invention is to: to the existing existing above-mentioned defective of real abdomen type U section steel beam, a kind of structure of lightweight U font girder steel is provided, overcomes the existing existing above-mentioned defective of real abdomen type U section steel beam.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: the through hole that stamps out row's equilateral triangle in the side plate middle part of two symmetries of U section steel beam; The alternately positive reciprocal permutation of described equilateral triangle through hole, the flanging that the oriented the same side of the oral area of each equilateral triangle through hole folds stamps out a strip convex tendon in the opposite direction with flanging between per two equilateral triangle through holes.
Beneficial effect: owing to the through hole and the strip convex tendon that stamp out row's equilateral triangle in middle part at U section steel beam side plate; The through hole position of equilateral triangle is not stress and stressed less position, so the through-hole section of equilateral triangle is very little to the overall load influence of girder steel; Simultaneously; A part of material that the through hole position of equilateral triangle is removed can alleviate the overall weight of girder steel effectively, alleviates the weight of building, helps the safety of building; In addition, the through hole oral area of equilateral triangle is folded to flanging on one side; And stamp out one between two equilateral triangle through holes and further strengthened the load-carrying ability of girder steel with flanging strip convex tendon in the opposite direction, so the present invention can reach the weight that both can alleviate girder steel; Simultaneously, can increase the load-carrying ability of girder steel again, help the safety of building; Reduce the construction cost of building.
Description of drawings
Accompanying drawing 1 is a structure principle chart of the present invention;
Shown in Fig. 1: 1, U section steel beam base plate; 2, U font girder steel side plate; 3, triangular hole; 4, long strip type convex tendon; 5, flanging.
The specific embodiment
Two side's side directions of U section steel beam base plate 1 are shaped on U font girder steel side plate limit 2 symmetrically; Stamp out the through hole 3 of row's equilateral triangle in the centre on U font girder steel side plate limit 2; The alternately positive reciprocal permutation of described equilateral triangle through hole 3, the flanging 5 that the oriented the same side of the oral area of each equilateral triangle through hole 3 folds stamps out a strip convex tendon 4 in the opposite direction with flanging between per two equilateral triangle through holes 3.
Claims (1)
