What Is Chimney Scaffolding?
The bowl buckle type multi-functional scaffolding is a new type of scaffolding developed on the basis of absorbing advanced joints and accessories technology of the same type of foreign scaffolding and combining with China's actual situation. The bowl buckle type multifunctional scaffold joint has a reasonable structure, simple manufacturing process, easy operation, and wide application range, and can fully meet the construction requirements of buildings such as houses, bridges and culverts, tunnels, chimneys, and water towers. Compared with other types of scaffolding, the bowl buckle type multi-functional scaffolding is a new type of scaffolding with broad development prospects.
- Bowl buckle scaffolding is a new type of socketed steel pipe scaffolding. Scaffolding has original toothed bowl buckle joints. It has the advantages of rapid disassembly, labor saving, stable and reliable structure, complete equipment, strong versatility, large bearing capacity, safe and reliable, easy to process, not easy to lose, easy to manage, easy to transport and widely used. , Stride to improve work efficiency. He has won various international and domestic awards several times, and is one of the ten key new technologies to be promoted by the Ministry of Construction before 2000 [1]
- The technical contents of 5.2, 5.4, and 5.6 of this standard are mandatory, and the remaining clauses are recommended.
- This standard was proposed by the Ministry of Housing and Urban-Rural Development of the People's Republic of China.
- This standard is under the jurisdiction of the Ministry of Housing and Urban-Rural Development of Construction Engineering Standards.
- This standard is drafted by: China Academy of Building Research.
- This standard specifies the terms and definitions, classifications, requirements, test methods, inspection rules, marking, packaging, transportation and storage of bowl buckle steel pipe scaffolding components.
This standard applies to the production and inspection of bowl buckle steel pipe scaffolding used in construction projects, such as bowl buckle steel pipe scaffolding and formwork supports. Also suitable for bowl buckle steel pipe scaffolding used in municipal, water conservancy, chemical, coal and shipbuilding projects
- The clauses in the following documents have become the clauses of this standard after being referenced. For dated references, all subsequent amendments (excluding the content of errata) or revisions are not applicable to this standard, however, parties who have reached an agreement in accordance with this standard are encouraged to study whether the latest written texts are applicable version. For undated references, the latest version applies to this standard.
- GB / T 700 carbon structural steel
- GB / T 2828.1 Technical sampling inspection procedures. Part 1: Batch inspection sampling plan retrieved by acceptance quality limit (AQL)
- GB / T 3091 Welding for low-pressure fluid transportation
- 1. The structure of the bowl buckle is reasonable, and the axial force transmission of the force bar makes the scaffold as a whole in three dimensions, high structural strength, good overall stability, and reliable self-locking performance, which can better meet
- (1) Multi-function: Single or double-row scaffolds, support racks, support columns, material lifting racks, climbing scaffolds, cantilever racks and other functions that can be composed of different groups of frame sizes, shapes and load capacities according to specific construction requirements Construction equipment. It can also be used to construct structures such as facility sheds, sheds, and lighthouses. Particularly suitable for setting up curved scaffolds and heavy-duty support frames.
- (2) Efficacy: The longest rod is 3130MM and weighs 17.07KG. The entire assembly and disassembly speed is 3 to 5 times faster than conventional, and the assembly and disassembly is fast and labor-saving. Workers can complete all operations with a hammer, avoiding many inconveniences caused by bolt operation
- (3) Strong universality: The main components are all steel pipes of ordinary fastener-type steel pipe scaffolding, which can be connected with ordinary steel pipes by fasteners, which has strong versatility.
- (4) Large bearing capacity: The vertical pole connection is coaxial, and the horizontal pole is connected with the vertical pole by a bowl buckle joint. The joint has reliable mechanical properties of bending resistance, shear resistance and torsion resistance. Moreover, the axis of each member intersects at one point, and the nodes are in the plane of the frame. Therefore, the structure is stable and reliable, and the bearing capacity is large. (The bearing capacity of the whole frame is improved, which is about 15% higher than the fastener-type steel pipe scaffold in the same situation.)
- (5) Safety and reliability: When designing the joint, the spiral friction force of the upper bowl buckle and the effect of self-gravity are considered to make the joint have a reliable self-locking ability. Acting on the crossbar
- 1) The cross bar is a shaped bar of several sizes, and the bowl buckle nodes on the vertical bar are set at a pitch of 0.6M, so that the size of the frame is limited;
- 2) U-shaped connecting pin is easy to lose;
- 3) The price is more expensive.
- 1) Construct various forms of scaffolding, formwork and other supporting frames;
- 2) Assembling the cross frame;
- 3) Set up ramps, sheds, stands and other temporary structures;
- 4) Construction of strong combined support columns; 5) Construction of support frames that can withstand lateral forces
- Upright
