1. What are the specification requirements for the turnbuckle scaffold?
1. Scaffold quality inspection. Before entering the construction site, the scaffold must undergo quality inspection, and the inspection is qualified, with a quality inspection report.
2. Select the site, and carry out quality inspection on the geology of the site to ensure that the ground is flat, the bearing capacity reaches the standard, and no collapse will occur. If the geology reaches the standard, the ground leveling problem can be adjusted by placing an adjustable base.
3. The erection and dismantling of the pan-buckle scaffold bracket must be held by a trained professional scaffolder with relevant certificates; Non-special operators shall not engage in erection operations. Scaffolder must wear safety helmet and fasten safety belt correctly when entering the construction site. Each scaffolder should be equipped with non-slip gloves, non-slip shoes and tool safety hooks or bags, and the working tools should be hung on the safety hooks or put into the bags.
4. When erecting the frame body, erect the first floor vertical pole, horizontal pole, vertical diagonal pole, and lay the platform steel springboard as required, and set the interval reasonably, according to the pre-approved erection requirements. Connect it according to the use requirements, and report it to the safety acceptance for standard use.
2. How to control the erection of the plate-buckle scaffold
1. Mark the dimensions according to the dimensions on the scaffold layout diagram and set out correctly. The setting range can be revised at any time with the erection of the bearing according to the design drawings or the designation of Party A..
2. After the pedestal is laid out, the adjustable pedestal is placed in a proper position. Pay attention to the base plate when placing, and materials with uneven base plate are strictly prohibited. The frame wrench is adjusted to about 25mm from the bottom plate in advance, which is convenient for adjusting the height of erection time. The main sleeve part of the standard base is jacked up on the bearing surface of the wrench, and the lower edge of the standard base is required to be completely placed in the groove of the bearing surface of the wrench. Apply the beam casting head position on the small hole of the disc, so that the front end of the beam casting head abuts against the circular tube of the main frame, and then use the inclined wedge to penetrate the small hole to finalize.
3. After the whole frame body is leveled, the frame body is on the same horizontal plane, and the levelness deviation of the frame body crossbar is not more than 5 mm.. The exposed length of the bottom plate adjusting screw rod of the utility model shall not exceed 3mm, and the height from the ground shall not exceed 55mm.
4. Arrange a vertical diagonal according to the design requirements. According to the requirements of the code, combined with the actual erection situation on site, the vertical diagonal arrangement is generally divided into two forms: matrix spiral (that is, lattice column) and eight symmetry (or V symmetry). In terms of specific implementation, it is mainly a plan.
5. Adjust the erection height of the frame body. Check the verticality of the frame. The allowable deviation of the verticality of the frame body (1.5m high) in each step is 5mm, and the allowable deviation of the overall verticality of the frame body is 5mm or 1mm (h is the overall height of the frame body).
6. The cantilever length of the adjustable bracket extending out of the top horizontal bar or double channel steel joist should not exceed 5mm, and the exposed length of the screw rod should not exceed 4mm. The length of the adjustable bracket inserted into the upright post or double channel steel joist should not be less than 2mm.
7. Structural measures such as column holding and Rachel of the frame body must meet the design requirements.
The above is all about the specification requirements and how to control the erection of turnbuckle scaffolding. I hope it can help you understand the relevant knowledge of turnbuckle scaffolding.
