The Components Of The Fire Door Manufacturer Shall Meet The Design Requirements And Specifications

The components shall meet the design requirements and specifications, and the main components (columns, crane beams, roof trusses, etc.) shall be rechecked. Components shall be protected from coating damage during transportation and installation. When the components of the fire door manufacturer are drilled, assembled and bolted at the installation site, they shall comply with relevant regulations. Dust, ice and snow, oil stain, soil and other sundries attached to the surface before component installation. When the structure needs strength test, it shall be carried out according to the design requirements and relevant standards. The installation process of steel structure shall ensure the structural stability and avoid member deformation. For components with poor stability, trial hoisting shall be carried out before hoisting, and formal hoisting can be carried out only after confirmation. After the column, beam, roof truss, support and other main components of the structure are installed in place, they shall be corrected and fixed immediately. For structures that cannot form a stable space system, temporary reinforcement shall be carried out. During the installation and correction of the two structures, the influence of external environment (wind force, temperature difference, sunshine, etc.) and deformation shall be considered. If the resulting deformation exceeds the allowable deviation, adjustment measures shall be taken. 62,2 construction preparation 1. The steel structure installation shall have the following design documents and steel structure design drawings; Architectural drawings: relevant foundation drawings: steel structure construction details; Other relevant drawings and technical documents.

Before the installation of steel structure, the self review and joint review of drawings shall be carried out and comply with the following provisions: be familiar with and master the contents of design documents; Find out the problems affecting component installation in the design; The fire door manufacturer proposes that the joint review with the building and other special drawings shall comply with the following provisions: the joint review of materials and basic design specifications of chapter boiler structure (1) drawings between projects shall be organized by the general contractor and participated by all project contractors, and shall comply with the following provisions. 2 basic provisions for light boiler structure design. 3 Calculation of steel structural components. ① the coordinates of foundation and column shall be consistent, The elevation shall meet the requirements for column installation. 2.4 calculation of ground action ② there is no contradiction with other engineering design documents; ③ Determine the construction procedures for cooperation with other projects.

The design of the basic components of the door fabric and the joint review of the drawings between the steel structure design, manufacturing and installation units shall comply with the following provisions: ① the design unit shall explain the design intention and put forward the process requirements; ② the production unit shall introduce the main manufacturing process of the steel structure; ③ the installation unit introduces the construction procedures and main methods, and puts forward specific requirements and suggestions to the design and production unit; Le shaped steel plate is used as measuring panel and density. 3. Coordinate the relationship between design, fabrication and installation. Construction organization design, construction scheme or operation design shall be prepared for steel structure installation. The construction organization design and construction scheme of the fourth Chabo car beam (1) shall be approved by the chief engineer, and its contents shall comply with the following provisions. Description of I-shaped crane beam ① introduction to project overview and characteristics ② calculation sentence structure of the fifth query 51 connection ② planning of general construction layout, energy, roads and temporary building facilities; General ball inspection seat connection and separation width ③ construction procedure and process design; ④ Layout and hoisting scheme of main hoisting machinery; Steel structure connection design example document transportation method, stacking and site management. Door drawing, connection and node design, construction network plan; Labor organization and employment plan, main machines and tools, material plans and technical quality standards. Hand volume of door light warp steel cleaning mechanism ① technical measures and cost reduction plan; Door light steel cleaning structure, quality assurance measures.
