scaffolding the impact of technology on project cost

With the accelerated pace of urban construction, high-rise building height tends, for quite a time, more and more high-rise buildings, which will bring a lot of construction technology appropriate changes. The traditional construction as auxiliary equipment, the project costs, labor, duration account for a large proportion, we should concern and attention scaffolding techniques.

General scaffolding (including floor-standing steel double scaffolding, etc.) is the traditional construction tools are widely adopted over the years. In recent years, lifting scaffolding attached to the development of new scaffolding, and has gradually evolved into a specialized construction equipment. Among them, lead-block attached to the scaffolding is used for vertical or tilt is not the facade of any structure, the high-rise buildings of the main works and external decoration works scaffolding, referred to as "climbing frame." Operate according to their theory, scaffolding can be increased step by step with the main construction progress, until the building cap, and then conduct these tasks can be decreased step by step, and finally back to the original installation location.

Compared with the floor-double scaffolding, guided seat lifting scaffolding has the following advantages:

① greatly reduce the material one-time investment that can improve the flow of materials utilization;

② simple and fast, less labor input, low labor intensity;

③ The process does not take crane, can speed up the construction progress;

④ reduce the cost of the project. Detailed comparison below.

Materials: floor-standing use of double steel pipe scaffolding, erection materials, such as multiple snap and consumed in large quantities; and climbing frame only comprehensive framework of consumption of 10%.

Artificial: the floor-double steel scaffolding erection, dismantling not only the operating environment when the risk of labor-intensive, and labor consumed in large quantities; and aircraft landing and taking off to climb a good operating environment, the labor intensity of small, integrated framework of artificial consumption lower than 50 % or so.

Safety: floor-double steel scaffolding erection, dismantling process is prone to accidents, poor safety; and climbing frame with fall protection, anti-tipping device, such as multiple simultaneous fault monitoring protection, safe and reliable.

Construction of civilization: the floor-double steel scaffolding throughout the construction process, constantly brought in a lot of material out of, transported on the transport, the aircraft is difficult to clean up under the debris, occupied the construction site, safety nets are also relatively large amount of maintenance; and climbing frames not occupied the construction site, the entire building facades clean and fresh.

Progress: the floor-double steel scaffolding erection only in the case of timely supply of materials in order to meet the construction requirements; while lifting speed climbing frame, about two days, you can layer up or down, and do not take crane to help accelerate progress in the overall schedule.

Inspection and maintenance: floor-double steel scaffolding inspection, maintenance engineering large, comprehensive inspection of work and a long life cycle costs; and climbing frame inspection and maintenance of the project was smaller, and a person 2 hours to conduct a comprehensive inspection.

With the external walls of the template used: floor-double steel scaffolding templates can only be used to support; climbing frame by the special design to increase the allocation to upgrade may bring the template, the template may not be landing wall. Erection of the material platform: The floor-double the number of steel scaffolding erection and more expensive; climbing frame erection of a small number of shelves can lift with low cost.

Other areas: floor-double steel scaffolding generally available more than 10 years, but the fasteners, bolts changed once every 3 years; climbing frame can also be used more than 10 years, but in need of repair and maintenance of electric equipment. In addition, can meet the glass wall and outdoor pipeline construction.

There are other relevant information that: when more layers, the total height is higher, the cost of using the lower climbing frame, the contrast more evident.
