Abstract

The utility model discloses a steel member adopting a steel reinforced beam column made of H-shaped section steel. A group of through holes (1a) are uniformly distributed in a middle wing plate of H-shaped section steel (1) in the length direction of the H-shaped section steel (1); spaces positioned on the two sides of the middle wing plate of H-shaped section steel (1), between an upper wing plate and a lower plate and in the through holes (1a) are filled with concrete (2); concrete (2) on the two sides of the middle wing plate of H-shaped section steel (1) are mutually connected. The steel reinforced beam column made of the H-shaped section steel can increase limit values of the width-to-thickness ratio and the height-to-thickness ratio of the H-shaped section steel; the steel reinforced beam column made of the H-shaped section steel, which has high width-to-thickness ratio and high height-to-thickness ratio, is provided.

Description

A kind of H shaped steel steel rib beam column

Technical field: the utility model relates to the steel member of building field, especially H shaped steel steel rib beam column.

Background technology: in steel construction, H shaped steel mainly, as beam, also can be used as post.H shaped steel is welded by top flange plate, middle wing plate, bottom wing listrium three block plates, and wherein upper and lower frange plate has part cantilever.The length of its bracketed part is called flakiness ratio with the ratio of thickness, and the height of middle wing plate is called ratio of height to thickness with the ratio of its thickness.The flakiness ratio of H shaped steel and ratio of height to thickness determine bulk strength, rigidity and the stability of this steel member.Therefore, H shaped steel is as steel member, and its flakiness ratio and ratio of height to thickness can not arbitrarily improve, but finite value, the size of limit value is different with the difference of rolling shapes.This is the intrinsic shortcoming of H shaped steel as steel member.

Utility model content: the purpose of this utility model is to provide a kind of H shaped steel steel rib beam column with high flakiness ratio and ratio of height to thickness, and still has higher bulk strength, rigidity and stability.

For this reason, the technical solution the utility model proposes is, a kind of H shaped steel steel rib beam column, is made the reinforcing bar of beam column, on the middle wing plate of H shaped steel by H shaped steel, along H shaped steel length direction, be evenly equipped with one group of through hole, the both sides of wing plate in H shaped steel, are filled with concrete in the cavity between upper and lower frange plate and in through hole, so the concrete via through holes of wing plate both sides is connected to each other in H shaped steel.

Therefore, H shaped steel between frange plate, filled up and down concrete, make upper and lower frange plate no longer include cantilever, this has just improved bulk strength, rigidity and the stability of H shaped steel steel member greatly, therefore can improve flakiness ratio and the ratio of height to thickness limit value of H shaped steel, a kind of H shaped steel steel rib beam column with high flakiness ratio and ratio of height to thickness is provided, still there is higher bulk strength, rigidity and stability.

Below in conjunction with drawings and Examples, the utility model is further described.

Accompanying drawing explanation: Fig. 1 is A-A section structure schematic diagram of the present utility model;

Fig. 2 is H shaped steel 1 in Fig. 1, weldering nail 3, the left view of steel fabric sheet 4;

Fig. 3 is the another kind of embodiment structural representation of through hole 1a in Fig. 2.

The specific embodiment: embodiment 1 as shown in Figure 1 and Figure 2.On the middle wing plate of H shaped steel 1, along the length direction of H shaped steel 1, be evenly equipped with one group of through hole 1a, through hole 1a is hexagon.The both sides of wing plate in H shaped steel 1, are filled with concrete 2 in the cavity between upper and lower frange plate and in through hole 1a, and in H shaped steel 1, the concrete 2 via through holes 1a of wing plate both sides interconnect, and like this, H shaped steel 1 just can not separate with concrete 2.Because H shaped steel has been filled concrete 2 between frange plate Shang Xia 1, so the frange plate up and down of H shaped steel 1 no longer includes cantilever, improve greatly bulk strength and rigidity and the stability of H shaped steel 1 as steel member.In addition, concrete 2 also can adopt foaming concrete, with weight reduction.

Embodiment 2 as shown in Figure 1 and Figure 2.The two sides of wing plate in H shaped steel 1, between every two through hole 1a, are all welded with one group of uniform weldering with middle wing plate lateral vertical of above-below direction and follow closely 3, and weldering nail 3 can be steel nail, can be also one section of reinforcing bar.Owing to having had, weldering nail 3, H shaped steel 1 is just more firm with being connected of concrete 2.Other are all identical with embodiment 1, no longer repeat.

Embodiment 3 increases steel fabric sheet 4 on the basis of embodiment 2.As shown in Figure 1 and Figure 2, at the soffit of H shaped steel 1 top flange plate, the upper surface of bottom wing listrium, the two sides of middle wing plate, are all welded with steel fabric sheet 4.Like this, concrete 2 is just more reliable with the combination of H shaped steel 1.

As shown in Figure 3, the through hole 1a in H shaped steel 1 on wing plate has adopted another kind of embodiment, i.e. circular hole to embodiment 4.Certainly can also adopt the through hole of other shapes, as quadrangle, octagon, ellipse, quincunx etc.Other are all identical with embodiment 3, no longer repeat.
