What are the specifications for scaffolding? What are the scaffolding specifications

Technical Code for Safety of Fastener-type Steel Pipe Scaffolding for Building Construction JGJ130-2001, Technical Code for Safety of Work at Height in Building Construction JGJ80-91, Code for Construction Quality and Acceptance of Concrete Structure Engineering GB50204-2002, etc.

1.The structural design of the frame body strives to make the structure safe and reliable, the cost is economical and reasonable, and the expected safety and durability can be fully met under the specified conditions and within the specified service life.

2.When selecting materials, we strive to achieve common general, turnover, easy to maintain and repair, and strive to achieve clear force, structural measures in place, easy to lift and disassemble, and easy to inspect and accept.

3.Based on the above points, the erection of scaffolding must also meet the requirements of JCJ59-99 inspection standards and the relevant standards of civilized standard construction sites.

4.Combined with the above scaffolding design principles, combined with the actual situation of the project, and comprehensively considering the previous construction experience, it was decided to adopt the following scaffolding scheme, ordinary cantilever frame.

5.External scaffolding refers to the scaffolding erected outside the outer wall, and its main structural forms include steel pipe fastener type, bowl buckle type, door type, square tower type, attached lifting scaffold and suspension scaffolding, etc., in the construction to vigorously promote bowl buckle scaffolding and door type scaffolding.

There are many specifications found on the website of SmartGen Building Resources: Safety Technical Specifications for Fastener-type Steel Pipe Scaffolding for Building Construction [with Explanation of Provisions] JGJ130-2011, Safety Technical Specifications for Tool-type Scaffolding for Building Construction [with Explanation of Provisions] JGJ202-2010, Safety Technical Specifications for Wood Scaffolding for Building Construction [with Explanation of Provisions] JGJ164-2008, Safety Technical Specifications for Bamboo Scaffolding for Building Construction [with Explanation of Provisions] JGJ254-2011, Safety Technical Code for Bowl Buckle Steel Pipe Scaffolding for Building Construction [Attached Description] JGJ166-2016, etc., specific requirements can be found in the corresponding specifications.

The structural design of the round and flat body strives to achieve that the structure should be safe and reliable, the cost is economical and reasonable, and the expected safety and durability can be fully met within the specified conditions and the specified service period.

When selecting materials, we strive to achieve common general, turnover, easy to maintain and repair, and strive to achieve clear force, structural measures in place, easy to dismantle, easy to inspect and accept.

When the floor scaffold is used as the foundation of the tower frame, the ground must be kept flat and solid, and there can be no water accumulation in the erection site, and the drainage ditch or other drainage measures should be set up on the outside and around the erection scaffold. It is necessary to have sufficient bearing capacity, and the support rod backing plate should meet the bearing capacity requirements, and the elevation of the bottom surface of the base should be 50-100mm higher than the natural floor.

Cantilever scaffold is mainly by setting up a cantilever beam at the edge of the building, through this cantilever beam, the scaffold load is transferred to the building structure in whole or in part, the frame body is firmly tied with the building through the tie piece, so as to meet the construction needs, in the specific construction process, usually the I-beam above 16, channel steel and other section steel are used as infrastructure, and the use of rebar is strictly prohibited.

Precautions for the use of scaffolding.

1. To erect high-rise scaffolding, all kinds of materials used must meet the quality requirements.

2. The foundation of high-rise scaffolding must be firm, calculated before erection, meet the load requirements, and erected according to the construction specifications, and do a good job of drainage measures. Knowing hands.

3. The technical requirements for scaffolding erection should comply with the relevant regulations.

4. We must attach great importance to various structural measures, and scissor braces and tie points should be set up as required.

5. The horizontal sealing of the tomb is closed, every other step or two steps, full of scaffolding board or scaffold fence, scaffold board is laid along the long direction, the joint should be overlapped on the small crossbar, and it is strictly forbidden to appear empty headboard. And between the pole and the wall, lay a long safety fence every four steps.
