Vertical span billboard shelf structure diagram
1. The dry-hanging method is also known as the empty hanging method. It is a new construction technology in current wall decoration. This method uses metal pendants to hang the facing stone directly on the wall or hang it on the steel frame without grouting and pasting. The principle is to set main stress points on the main structure, and fix the stone on the building through metal pendants to form a stone decorative curtain wall.
2. Install the horizontal angle steel frame after the horizontal joints of the marble: Determine the location where the billboard is to be installed, remove the stone as a whole at the fixed point, and fix the advertising frame with angle steel welding. The advertising rack must be connected to the steel structure with an angle steel of more than 30 degrees. When positioning, try to allow the advertising rack to cover the space left by removing the stone.
Extended information:1. Clear the installation sequence: column hoisting → billboard frame installation → billboard surface installation → sporadic component installation.
2. Foundation review: Arrange relevant technical personnel to measure and review the foundation before installation. The inspection content includes: the foundation plane must be flat, without cracks, honeycombs, exposed ribs, etc.; the transverse centerline of the foundation and The longitudinal centerline should be vertical; the basic outline size deviation should not be greater than 20mm.
3. The installation location of the installation vehicle must be selected based on the criteria of stable geological conditions and no harm to the greening; the lifting height should not be too high or too low, and the height of the lifting firmware and installation needs should be adjusted appropriately; use cables The wind rope adjusts the verticality of the column to pre vent personnel from approaching for adjustment, which may cause safety hazards; the theodolite should be used to verify that the verticality of the installation is less than 10mm.
4. When installing billboards, in addition to paying attention to safety issues during the hoisting process, you must also pay attention to the firmness of the welding and the anti-corrosion work at the joints; pay attention to adjusting the billboard frame during the hoisting and lifting process. Whether to tilt or not, adjust continuously until it reaches a safe position. The entire process is directed by a dedicated person and equipped with a whistle to unify the operation.
5. Complete the installation of the light frame and other components according to the picture.
