Design features of steel structure workshop and matters needing attention in installation

(a), steel structure plant design has what characteristics

Because our country's steel production increase, more and more enterprises begin to use the steel structure design of steel structure workshop, steel structure workshop is divided into light steel structure workshop and chongqing steel structure workshop, the main bearing component is composed of steel, steel columns, steel beam, steel structure foundation contains, it is different from traditional brick factory, has the following features: 1, steel structure design workshop steel plasticity is good, the structure in general not due to accidental overload or local overload and suddenly fracture. The toughness of steel makes the structure more adaptable to dynamic load.

2, steel structure design workshop used steel material uniformity, structure;

3, steel structure design workshop used steel, light weight structure, manufacturing workshop span, can be made into a large span of the structure;

4, steel structure factory steel has weldability, the connection of steel structure is greatly simplified, suitable for manufacturing a variety of complex shape structure;

5, steel structure production, installation of the degree of industrialization of the production of high steel structure is mainly carried out in the chemical metal structure plant, so the production is simple,. Made of components transported to the site for installation, high degree of assembly, installation, short period of time.

Of course, steel structure design workshop is also specific to other characteristics, such as heat resistance and fire resistance, corrosion is poor, should try to avoid wet environment. But in general, steel structure workshop, large span, steel structure construction period is short, corresponding to reduce the cost of investment, more and more welcomed by enterprises and manufacturers.

(b) Matters needing attention in the installation of steel structure

The steel structure manufacturer not only undertakes the production of various spare parts of the steel frame structure, but also undertakes the overall installation of the steel frame structure. In general, steel structure engineering in the construction of the convenient measurement, and to carry out pre-installation test, the whole process of engineering construction no problem. The key points of steel frame structure installation include the following aspects:

1, the prefabrication of steel prefabricated components, in accordance with the installation sequence and processing technology provisions on the steel platform to carry out the prefabrication and assembly of steel prefabricated components, to make quality welding.

2, channel steel splicing flange plate splicing joint and beam end splicing joint interval should be more than 200㎜. Flange plate splicing length should not be less than 2 times the width of the plate; Beam end splicing total width should not be less than 300 mm, length should not be less than 600 mm.

3, in order to convenient welding, welding quality, as far as possible will pole, bearing beam on the reinforcement plate, connecting plate, pad block, pick beam (beam) on the road steel platform according to the construction drawings specifications to carry out welding check.

4. In addition to assembling the prefabricated steel prefabricated components on the steel platform according to the construction drawings and standard provisions, the technological performance and the change of installation specifications should also be taken into account.
