Steel Structure Platform of Steel Structure Engineering

In the process of steel structure project construction, the general modern steel structure platform structure has the advantages of diversified forms, complete functions and wide application. The biggest feature of its structure is fully assembled structure, flexible design, which can be designed and manufactured according to different site conditions to meet the requirements of the site, the use of functional requirements and meet the logistics requirements of the steel structure platform.

Arrangement of steel structure platform

　　1. Determine the plane size of the structural platform, elevation, beam space frame and column network layout in addition to meet the requirements of the use of beams, columns, the arrangement should be considered on the platform of the equipment load and other large centralized load location and large-diameter industrial pipeline hanging and so on;

　　2. The arrangement of the structural platform should strive to achieve economically rational, direct and clear force transmission. The arrangement of the beam space frame should be compatible with its span. When the span of the beam is larger, its spacing is also appropriate to increase. Make full use of the permissible span of the slab, reasonable arrangement of the beam grid, in order to achieve better economic results.

        3.Meet the requirements of process production and operation, and ensure the clearance of passage and operation. General access to the net height should not be less than 1.8M, the platform should be set up around the general protection railing, railing height is generally 1M. when the platform height is greater than 2M, should be set up under the protection railing height of 100-150mm skirting board. Platform should be set for up and down the ladder, ladder width should not be less than 600mm.

The composition and classification of structural platform

　　1. Composition: the platform structure usually consists of paving slabs, main and secondary beams, columns, inter-column supports, as well as ladders, railings and other components.

　　2. Classification: according to the use of requirements can be divided into indoor and room on the platform, bear static load and power load platform, production auxiliary platform, as well as medium and heavy operation platform. According to the different ways of handling the support, the platform structure can also be divided into:

　　1) all for independent platform. Subject to a large power load or a heavy reason for a large equipment platform, it is appropriate to design with the plant columns to disengage, directly supported on the independent columns.

　　2) directly resting on the plant column tripod or cattle leg platform, the function is usually a safe passage or a simple medium-sized operating platform.

　　3) One side of the support in the plant column or building wall, the other side of the platform with independent columns.

　　4)platform supported on large equipment.

　　Steel structure platform is an independent system in steel structure, which can be indoor or outdoor. According to the established standards and requirements, the construction process is reasonably arranged so that the construction of steel structure platform can meet the application requirements.
