Detailed description of the invention
By reference to the accompanying drawings, structure of the present utility model and principle are described.Shaped steel of the present utility model and reinforced concrete combination oblique
Mainly comprise to post: reinforced concrete post 1 and the steel column 2 being positioned at reinforced concrete post side.
Steel column is arranged along the length direction of described reinforced concrete post, and is fixed by weldering nail 3 and described reinforced concrete post 1, and the cross section of steel column is welding box-shaped cross section; Reinforced concrete post and steel column are obliquely installed, and the angle of slope of reinforced concrete post and cross sectional dimensions, under the requirement meeting construction conditions, make moment of flexure at the bottom of the post of reinforced concrete post be reduced to expection requirement.That is, when designing, reinforced concrete post of the present utility model has and is meeting moment of flexure at the bottom of its (reinforced concrete post) post can be made under construction conditions requirement to be reduced to angle of slope that expection requires and cross sectional dimensions.
In a preferred embodiment, the cross section of reinforced concrete post is square-section, and strength grade of concrete is not less than C40, and arrangement of reinforcement meets the requirement of engineering specifications, such as, need the regulation meeting GB50010-2010.Weldering nail is
Φ13 ~ 16mm, the distance between adjacent weldering nail is not more than 200mm.
In a further embodiment, two pieces of parallel webs 24 that the structure of box steel column specifically comprises the first end plate 23, second end plate 25 parallel with the first end plate, two ends are welded with the first end plate and the second end plate respectively, and two ends are welded in dividing plate 22 between web and parallel with the first end plate or the second end plate respectively, described dividing plate is equal to the distance of the first end plate and the second end plate, described weldering nail is two rows, and often the outside the junction being welded in the second end plate and web that are positioned at the second end plate are followed closely in row's weldering.Should be large biasing member by post member designs when designing, must ensure that steel column outer side wing edge is in tension state when ultimate limit state.
In a still further embodiment, steel column also comprises a junction 21, and this connecting portion extends in reinforced concrete post.
In certain Project case, the cross sectional dimensions of reinforced concrete post is 800mm × 800mm, and the length of the first end plate and the second end plate is 500mm, and the parameter of pin is 16 × 200, and the length of dividing plate and the thickness sum of web are 300mm.
Forwarding Fig. 3 to, stressing conditions of the present utility model is described, is on the right side of Fig. 3 under the effect of external loads 101 with deadweight 102, bending moment diagram of the present utility model.External loads 101 is delivered to basis by post component, wherein as the composition of bias voltage tensional element, the outer coxostermum of steel column bears tensile stress, concrete column bears compressive stress, connect weldering nail steel column is reliably connected with concrete column and between the two Transfer of Shear, therefore can make full use of the advantage performance of material.
And, while giving full play to the good Compressive Performance of steel concrete and steel work examining tensile behavior, architectural space can be saved and reduce building costs.
