  • Description:

    1, steel tube scaffold application 48 ~ 51 mm outside diameter, wall thickness 3 ~ 3.5 mm, no serious erosion, bending, flattening or crack of steel pipe, steel pipe punching is forbidden.

     

    2, steel tube scaffold bar connection must use qualified steel fasteners, lead wire and other materials shall be used for binding;

     

    3, scaffolding steel stud spacing shall not be more than 1.8 m, big bar spacing shall not be more than 1.8 m, small bar spacing is not more than 1.5 m, the ladder spacing shall not be more than 0.5 m.

     

    4, the platform of peripheral must set up the fence and block pedal. Fence height is 1.2 m, block pedal height should not be less than 150 mm.

     

    5, scaffolding must ensure that the structure deformation, every level in more than 20 m scaffold, longitudinal must set bracing, its width must not exceed 7 lever, and the horizontal plane Angle should be 45 to 60 degrees. Height under the 20 m, you must set up positive and negative inclined support.

     

    6, old fastener quality inspection should be done before use, have cracks, deformation, is strictly prohibited appear smooth silk bolts must be replaced, fasteners shall be antirust processing.

     

    7, steel pipe surface should be flat and smooth, there should be no cracks, scarring, layered, dislocation, hard to bend, burr, indentation, and deep way.

     

    8, the bar end out of fastener cover plate edge should not be less than 100 mm in length.

     

    9, the structure of the longitudinal rod shall meet the following requirements: (1) longitudinal rod should be installed in the vertical bar inside, its length should not be less than 3 across. (2) longitudinal rod extension appropriate USES docking fastener connection, overlap may be adopted.

     

    The slips, and receive, meet the following requirements: 1) the longitudinal uneven bar docking fasteners should be staggered, two adjacent longitudinal rod joint should not be set within the synchronization or with cross. Out of sync or different across two adjacent joint in horizontal direction staggered distance should be not less than 500 mm; The joint center recently to the master node distance should not be greater than 1/3 of the longitudinal spacing. 2) the lap length should be not less than 1 m, should be equally spaced set three fixed rotating fastener, end fastener cover plate edge to lap the longitudinal rod rod end distance should be not less than 100 mm. 10,

     

    Lateral horizontal rod structure shall meet the following requirements: (1) the main node must set a lateral horizontal pole, dismantling right-angle fastener hooking and it is strictly prohibited. The master node center distance of the two right-angle fastener should not be greater than 150 mm. (2) the operation level of the main node lateral horizontal bar, should according to the needs of supporting scaffold board spacing Settings, such as the largest spacing should be not more than half of the column spacing.

     

    11, the setting of scaffolding shall meet the following requirements: (1) operation layer scaffold board shall spread and spread, leave the metope of 120 ~ 150 mm; (2) scaffold board, etc., should be set on the three lateral horizontal bar. When scaffold board length less than 2 m, can adopt two lateral horizontal rod bearing, but its reliable fixed on both ends of the scaffolding, should be protected from tilting. Scaffolding docking tile, junction must set two lateral horizontal pole, scaffolding elongation should take 130 ~ 150 mm, two pieces of scaffolding overhang and should not be greater than 300 mm in length. Scaffolding lap lay, joint must be supported on the lateral horizontal pole, lap length should be greater than 200 mm, the stretched out the length of the lateral horizontal bar should not be less than 100 mm.

     

    12, vertical rod (1) each stud or plate should be set at the bottom of the base. (2) the scaffold must be set longitudinal and transverse rod sweeps the floor. Longitudinal rod sweeps the floor should be right-angle fastener epithelial no greater than 200 mm from the base of the stud. Transverse rod sweeps the floor should also be using right-angle fastener fixed in close to the vertical sweeping bar at the bottom of the stem. When the vertical rod based not on the same height, longitudinal rod sweeps the floor must be high to low for two across and vertical rod is fixed, height difference should not be greater than 1 m. Stand on the slope at the top of the stem axis to slope distance should not be less than 500 mm.

     

    13, scaffolding before use should hang “qualified allowed” brand, and by the maintenance and repair work, head of the acceptance of rear can use.
