Background

In recent years, the steel industry in China is continuously and rapidly developed, and the steel yield is rapidly improved, so that the steel industry becomes the first major steel country in the world. The steel structure engineering has the advantages of environmental protection, energy conservation, short construction period and the like. The government of China also puts forward a policy of 'vigorously developing steel structures'. At present, domestic boilers of high-parameter and high-capacity power plants all adopt an H-shaped steel structure form.

In the construction of a steel structure, the determination of construction schemes in the aspects of mounting brackets of H-shaped steel beam column heads required in node mounting, erecting scaffolds required by equipment mounting and the like is the key point of engineering construction. At present, each construction unit has different construction schemes and methods, and most of the schemes are not ideal in the aspects of economy, safety, construction period control and the like.

3. Contacting with steel structure manufacturers, directly drilling bolt holes at proper positions of wing plates of the H-shaped steel, and fixing angle steel, channel steel or other section steel on the H-shaped steel structure by using bolts. This approach, in addition to the disadvantages of the second approach, also causes permanent damage to the steel structure.

Taking the scaffold needed by equipment installation as an example, the following erection modes exist at present:

1. directly set up the floor type scaffold. The method mainly has the following technical defects that firstly, too many scaffolds are arranged on a construction site, and the method is inconvenient to pass, arrange for construction and the like and is not beneficial to safety; secondly, a large amount of scaffold materials are needed; and thirdly, if the geometric dimension between the two steel structures is overlarge, the steel structure is not suitable for use.

2. The high scaffold adopts a method of packing hoops on H-shaped steel, four scaffold rods and four cross fasteners are used for packing the H-shaped steel, and then the scaffold is erected on the packing hoops. The following technical defects mainly exist: firstly, the fixing is not firm and the sliding is easy; secondly, the used cross fastener is easy to damage and is a great potential safety hazard; and thirdly, the material investment and the manual investment are large.
