What are the regulations for erecting construction scaffolding?

The construction scaffolding erection specifications are very important. The use of specifications depends on the experience of every detail, which is very critical when choosing. Zhongda Consulting would like to briefly explain to you the construction scaffolding erection specifications.

1. Foreword

(1) The erection and construction management of fastener-type steel pipe exterior scaffolding in construction reflect the company’s characteristic exterior scaffolding image and standardized construction capabilities. This standard is in accordance with the national In accordance with relevant local safety technical specifications, the "Internal Standards for the Erection of External Scaffolding in Construction Projects" was compiled.

(2) This standard makes specific statements on the facade image, structural requirements, erection and dismantling, inspection and acceptance, and management requirements of external scaffolding, and details the construction methods of some special parts. The detailed parts mainly include: balconies, bay windows, external elevator unloading platforms, elevator shafts and lighting wells, and sun corners of buildings, etc.

(3) If the specific content of this standard is inconsistent with the requirements of relevant national and local safety technical regulations, the relevant national and local safety technical regulations shall prevail.

2. Basic parameter requirements

(1) Steel pipe material requirements: The steel pipe should be Q235 ordinary steel pipe specified in the national standard GB/T13793 or GB/T3091, and the model should be Φ48. 3×3.6mm (the plan is calculated based on Φ48×3.0mm). When the material comes to the site, the product certificate must be provided and accepted. It can be put into use only after it is qualified.

(2) When fasteners enter the construction site, the product certificate should be checked and sampling retests should be carried out. The technical performance should comply with the national standard "Steel Pipe Scaffolding Fasteners". The appearance of the fasteners should be inspected without cracks. When the bolt tightening torque reaches 65N?m, damage shall not occur.

(3) The steel pipes of the outer scaffolding must be rust-proofed. After rust removal, apply one coat of anti-rust paint and two coats of topcoat.

(4) The wooden scaffolding board model is 3000 (6000) × 200 (250) × 50, and the two ends are bound with Φ1.6mm galvanized iron wire; the reinforced mesh scaffolding is made of HPB235Φ6 steel bars with a section spacing of 40mm, and is used Φ1.6mm galvanized iron wire is fixed on the small crossbar.

3 Steel pipe colors

(1) Yellow paint: scaffolding poles, large and small horizontal poles, vertical and horizontal sweeping poles.

(2) Red paint: attached to the wall.

(3) Yellow and black two-color paint: protective railings on the outside of the scaffolding, protective railings on the ramp, and protective railings on the unloading platform.

(4) Red and white two-color paint: scissor braces, transverse diagonal braces, skirting boards, stair edge protective railings, and construction elevator unloading platform edge protective railings.

(2) Vertical and horizontal horizontal rods must be set at the main node.

(3) The vertical poles must be butt-jointed except for the top of the top floor. The large horizontal poles can be overlapped outside the corners of the frame, and the scissor braces must be overlapped.

(4) Scissor braces and wall-connecting parts must be erected and dismantled simultaneously with the external scaffolding. It is strictly prohibited to put it up later or dismantle it first.
