scaffolding construction fastener technology
Construction steel tubular scaffolding template template support bracket must be set to horizontal and vertical sweeping strokes. Vertical sweep shot should be fixed at right angles from the base of epithelial fasteners not more than 198mm at the pole, the horizontal sweep shot should be fixed by right-angle fastener close to the bottom of the vertical pole on a sweeping stroke. When the pole is not the same height on the basis, you must sweep the floor height of the vertical bars extend to the lower pole fixed with two spans, the height difference should not exceed 1.5m. Pole by the axis of the slope to the top of the slope distance of not less than 498mm. Steel stents should be used a template standard φ48 × 3.5mm, wall thickness of not less than 2.7mm. On the non-perforated pipe.
1. Take a long pole can be used in addition lap top step, the remaining steps must be docking connector fastener connection. Butt, lap should meet the following requirements: lap length of not less than 1m, should be fixed not less than 2 rotary fastener, fastening the cover end to the rod end from the edge of not less than 98mm, pole injury Fasteners should be staggered in the docking, the joints should not be two adjacent pole set in the synchronization;
2. Fastener appearance quality requirements: There are cracks, deformation or sliding wire fastener bolts appear strictly prohibited;
3. Erection of steel used in the template frame, fasteners, must be carried out sampling and testing before use, the number of sampling in accordance with relevant regulations. Testing or testing without fail will not be allowed to use.
4. Demolition work must be carried out step by step from top to bottom, is strictly prohibited and down simultaneously. Section removed should not exceed two-step height. Connections with the template attached to the wall bracket, connectors must be removed with the support layer, non-first connector removal of all or a few steps after the removal of stent.
5. Construction load on the operational level shall meet the design requirements, shall not be overloaded. not connected with the template scaffold scaffolding.
6. Template support is in use, shall not remove any bar. When the template frame basis or adjacent equipment at a base, trench, in the excavation shall support use of the process, or reinforcement measures must be taken to 9.
7. Master node must be set at the level of a horizontal pole, Snap fastener with a right angle and the non-scaffolding removed. Master node from the center of the two right-angle fastener should not exceed 150mm.
