Production, installation and maintenance of three wall advertising signs
Three billboards should be installed on sturdy metal supports or on the walls of buildings. The bottom bracket design and by the buyer itself, and the strict calculation of the compressive strength and wind strength of the foundation support are necessary so that it can meet the compressive strength requirements of the metal support and the dead weight of the three sides of the billboard, and meet the local wind resistance requirements of the maximum wind force.
1. Pedestal bracket: three billboards should be installed on the solid metal bracket or wall of the building. The bottom bracket design and by the buyer itself, and the strict calculation of the compressive strength and wind strength of the foundation support are necessary so that it can meet the compressive strength requirements of the metal support and the dead weight of the three sides of the billboard, and meet the local wind resistance requirements of the maximum wind force.
If the three billboards are installed on the metal bracket, the back of the bracket is completely enclosed by an iron plate, so as not to backlight and affect the picture effect. Accuracy requirements of foundation support: a, horizontal beam, vertical column. b. In the direction of screen length, the non-uniformity of upper and lower beams is less than 10mm, and in the direction of screen height, the non-parallelism of upper and lower beams is less than 20mm.
Base support production strength requirements: the lower beam is a load-bearing structure, supporting the weight of the three flip billboards, and the elastic deformation at each point connected to the three flip billboards shall not exceed 2mm.
Special reminder: the design and manufacture of basic support should be designed and manufactured by professional and technical personnel with grade qualification.
2.Installation steps: install the upper and lower outer frame (the inner angle of the outer frame is 90 degrees) fixed on the bracket, the left and right outer frame is connected with the upper and lower frame, and finally install the prism picture.
3. Replace the screen: first turn off the power and lift the prism 20mm. Then move the prism horizontally from the bottom, and the upper end of the prism is automatically interrupted. Post-it pictures are usually glued, can be cut into several 140 mm wide longitudinal, numbered in order to paste in the triangular prism (in disassembly and movement, the triangular column can not be strongly affected to prevent the permanent deformation of the triangular column, which will cause the operation to fail). The main power supply should be turned off before using mechanical equipment to repair the rack.
Steel gears between the motor and the driving spindle should be lubricated and buttered every six months.
Triangular prism drive cam disk is made of synthetic material, has self-lubricating function, does not need any lubricant.
Picture and frame cleaning
clean with a low pressure water spray gun and then dry (do not clean during frost season). Other photo production and lighting: in addition to nude signs and basic support, the three billboards also involve picture production and lighting.
Photo production: computer printing. Recommended: 300 dpi. Material: high quality outdoor paste (outdoor ink must be used and sprayed (covered) UV protective film)
