[ technical field ] A method for producing a semiconductor device
The utility model relates to a building element, concretely relates to novel concrete cladding steel column belongs to building engineering technical field.
[ background of the invention ]
China is vigorously promoting the transformation of traditional buildings to industrialized buildings, and common H-shaped steel columns are mostly used in steel structures and fabricated buildings. However, the weak axis bending rigidity of the ordinary H-shaped steel column is small, and the column is easily unstable around the weak axis under axial pressure. If two steel plates are adopted for welding between two channel steel, although the turning radius of the section is enhanced, the working hours of welding seams are increased.
Therefore, in order to solve the above technical problems, it is necessary to provide a novel concrete-coated steel column to overcome the above-mentioned drawbacks of the prior art.
[ Utility model ] content
In order to solve the problems, the utility model aims to provide a novel concrete-coated steel column with simple structure, great bending rigidity and good fireproof performance.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a novel concrete-coated steel column comprises a channel steel I, a channel steel II, a connecting web plate and a concrete layer; the channel steel I and the channel steel II are arranged oppositely and have the same structure; the channel steel I comprises a substrate and flanges positioned on two sides of the substrate; the connecting web plate is welded in the middle between the channel steel I and the channel steel II; the concrete layer is filled in the channel steel I and the channel steel II and connected with two sides of the web plate.
The utility model discloses a novel concrete cladding steel column further sets up to: a plurality of round holes are formed in the connecting web plate, and the concrete layer penetrates through the round holes.
The utility model discloses a novel concrete cladding steel column further sets up to: the flange is formed by bending two ends of the substrate, so that the channel steel I and the channel steel II are both of an integrally formed structure.
The utility model discloses a novel concrete cladding steel column further sets up to: the base plate and the connecting web plate form H-shaped steel; the flanges are welded to the two sides of the base plate.
The utility model discloses a novel concrete cladding steel column still can set up to: the flanges are parallel to the connecting web.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. the utility model discloses a novel concrete cladding steel column adopts on the basis of ordinary H shaped steel for the edge of a wing both ends of shaped steel are outwards extended, and the extension is parallel with the web, makes the weak axle bending stiffness increase in shaped steel cross-section, has improved the stability of steel column simultaneously.
2. For department's welding steel sheet in the shaped steel outside, the utility model discloses a novel concrete cladding steel column adopts this kind of novel shaped steel cross-section, and reducible welding seam point quantity effectively practices thrift construction process time, and then practices thrift engineering cost.
3. The utility model discloses a novel concrete cladding steel column has effectively increased the rigidity of post after adopting this kind of novel shaped steel cross-section to and the stability of post has effectively been increased.
4. The utility model discloses a novel concrete cladding steel column is in web department division hole, once pours the concrete, has improved the fire behavior of post greatly, reduces fire retardant coating's use.

The channel steel I comprises a base plate 5 and flanges 6 positioned on two sides of the base plate 5. In the present embodiment, the flanges 6 are formed by bending both ends of the substrate 5, so that the channel I1 and the channel II2 are both integrally formed, thereby facilitating manufacturing, enhancing structural strength, and reducing welding.
The connecting web 3 is welded at an intermediate position between the channel I1 and the channel II 2. The flanges 6 are parallel to the connecting web 3. In the present embodiment, the connecting web 3 is provided as one piece.
The concrete layer 4 is filled in the channel I1 and the channel II2 and connects two sides of the web 3. A plurality of round holes 7 are formed in the connecting web plate 4, and the concrete layer 4 penetrates through the round holes 7, so that the occlusion force of the concrete layer 4 and a steel structure is enhanced, and the overall quality of the steel column is reduced.
Please refer to fig. 3 in the specification, which is a second embodiment of the novel concrete-coated steel column of the present invention, and the difference between the second embodiment and the first embodiment is: the base plate 5 and the connecting web plate 3 form an H-shaped steel 8; the flanges 6 are welded to both sides of the base plate 5.
The utility model discloses a novel construction process flow of concrete cladding steel column as follows: firstly, blanking preparation is carried out on section steel parts, and then section steel assembly is carried out. And welding the section steel to finally form a finished product.
The utility model discloses a novel concrete cladding steel column adopts the overhanging shaped steel cross-section in edge of a wing, and the extension is parallel with the web for the radius of gyration increase of the weak axle in post cross-section, the weak axle bending stiffness increase in shaped steel cross-section has improved the stability of steel column, and the fire prevention of steel column is anticorrosive can adopt the mode of outsourcing concrete simultaneously, practices thrift steel column fire prevention cost.
The above embodiments are merely preferred embodiments of the present disclosure, which are not intended to limit the present disclosure, and any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present disclosure, should be included in the scope of the present disclosure.
