Installation Requirements For Steel Grid Plate

Steel grating is a kind of grid plate product which is economical and reasonable, saves steel and can meet the requirements of use. It has been widely used in all walks of life. The characteristics of the steel grating are the characteristics of high strength, beautiful appearance, saving cost and convenient installation. Under the premise of ensuring the safety and quality, combined with the actual situation of the site, considering the construction progress and construction convenience, we will talk about the installation technology requirements and matters needing attention of the grid steel plate.

Installation requirements for steel grid plate

(1) before the installation of the steel grating, the inspection shall be carried out according to the design requirements of the drawings, and the unqualified inspection shall not be used on this project.

(2) the installation order must be determined before the installation of the steel grid plate, which is installed in turn with the number of the grille plate of the drawing.

(3) steel plate installation process shall be laid from the structure of the first layer of the ladder to the surrounding

(4) each install a steel plate to put the fastener (each plate number of erection clip were not less than 2)

Spot welding firm, steel plate must install a fixed piece, no steel plate fixed prohibited to stand homework, do not allow the removal of temporary protective measures.

(5) the steel grid plate shall not be accumulated on the steel beam, and the height of the steel lattice board can not be accumulated over 1.2 m.

(6) 2 meters of steel sheet work must be 100% fasten seat belt, unconditionally fasten the safety belt to set the life rope.

(7) the staffs should be small tools in the tool bag, do not allow the small tools and accessories (hammer, wrench, crowbar, electrode etc.) directly on the steel plate, to prevent falling objects wounding.

(8) fire prevention measures should be implemented before electrical welding and modification to prevent fire or personnel scald.

(9) the work of the steel sheet laying, in principle, not allowed to cross two or more layers at the same time. If cross operation is required, there must be an effective isolation facility between the two operating layers.

(10) there should be protective measures to carry, lift, pry, and move steel plates to prevent the falling of steel sheet and workers.

(11) during the operation, the dangerous area under the operation should be enclosed or set up a warning sign, and the guardian should be set up.

(12) bad weather, such as frost, snow, wind and rain, is not allowed to carry out high altitude steel grid work. If necessary, effective anti-skid, communication measures and good vision should be taken.

(13) during operation, site cleaning is needed. Tools and cutting metal materials can not be stacked near the grille openings in the process of being installed or dismantled. The leftover materials must be recovered in time to prevent falling objects from hitting and scalding.

(14) after the completion of the operation, the construction unit will return the license of "completed work" to the person in charge of the project HSE. The grid board is fully installed and installed, or the local installation is required to enter the next process. After acceptance of the project department, it can be used for delivery.

(15) the abandoned holes, holes and mouth must be permanently closed according to the provisions of the grille, and can be used after acceptance.

(16) the setting of platform beams should consider the shelving length of both ends of the steel grille on the beam, the shelving length is not less than 25mm, the installation gap of the two steel grille is 0 to 15mm, the longest length of each panel is 4m, and the spacing of two shelving beams should not be greater than 4m.

(17) the steel grille should be disassembled on the ground before installation, and should be classified according to the number of board drawings and the order of installation.
