Light steel keel welding between what method?
Ceiling, such as the installation of a walkway, should be attached to the additional hanging system, with lOmm boom and the length of 1200mm L15 × 5 angle crossbar with bolts, cross the distance of 1800 ~ 2000mm, in the crossbar laying aisle, Can be used 6-channel two spacing 600mm, between the steel with lOmm welded, the spacing of steel lOOmm, the slot
? Steel and cross-angle steel welding firm, in the side of the aisle with railings, height of 900mm can be used L50 × 4. Angle steel column, welded in the aisle channel, between the 30 × 4 flat steel connection.
The ceiling plate should be separated in the middle of the room, so symmetrical, light steel keel and board arrangement from the middle of the room to the two sides in turn installed, so that the roof layout neat
(1) the main keel should hang hanging on the boom, the main keel spacing of 900 ~ lOOOmm. The main keel is divided into two kinds of human UC38 keel, superior UC60 keel. The main keel should be parallel to the room long to An Pei, at the same time should be arch, from the arch height of the room span of 1/200 ~ 1/3000 main keel cantilever should not be greater than 300mm, or should increase the boom main keel should be long Take docking, adjacent keel docking joints to be staggered from each other. After the main keel hanging should be basically flat.
(2) span greater than 15m above the ceiling, should be on the main keel, every 15m plus a large keel, and vertical main keel welding firm.
(3) If there is a large modeling ceiling, the shape part of the application of angle steel or flat steel welded into a frame, and should be connected with the floor firmly.
