The balcony guardrail construction methods of the specific process:
1, balcony guardrail cleaning at the grass-roots level
Railings before installation on the balcony guardrail, beam, line inspection earnestly, will base on the board face clean up dust, dirt, etc, check whether the balcony installation site is flat and level.
2, balcony guardrail embedded parts installation
Railings installation of embedded parts can only be used after add up, its practice is to use bolts (M8 * 100 mm) and plate (100 * 100 * 5 mm thick) to make the rear connectors. First pay-off in civil engineering at the grass-roots level, determine the position of the pillar fixed point, and then in the installation position with percussion drill hole, then install the expansion bolts, the length of the bolt to keep enough, after the bolt positioning, tighten bolts between the nut and screw welded to death at the same time, to prevent the nut with steel plate is loose.
3, balcony protect stockade of finished product installation
(1) the rail installation: installed check rail installation location before, meets the installation requirements. Check and start the installation, when installation, need to double match, a vertical and hold the rail to keep its flatness. After welding from the spot welding on both ends against the wall reinforcement, check whether the railings installation is flat and vertical, and then strengthen the railings root welding. After being early railings installation requirements, spot welding reinforcement installation, can not shake when welding, welding to around welding, weld closely and shall comply with the welding specification.
(2) the balcony guardrail installation must be installed by a professional unit construction. First pull wire, straight, ensure upper and lower levels, and demanded that the bar height not less than 1.1 m, parapet spacing is not more than 0.11 m; Check the fence installation of embedded parts in quantity, specifications, location, and guardrail and embedded parts connected nodes comply with the design requirements.
4, grinding polishing:
Before they leave the balcony guardrail have according to the size of design drawings all the good welding, and the welding welds with grinding wheel to draw with sanding, until do not show weld.
5, powder coating:
Before spraying the rail surface must be clean up the oil, rust and other rubbish. Spraying should level off, smooth, cannot have mixed color, garbage and agglomerate, floral surface texture clear.
