Description

Bowstring truss type fully enclosed hydraulic climbing formwork system

technical field

The utility model belongs to the fully enclosed construction formwork technology of super high-rise buildings, which is used for the structural construction of super high-rise buildings, provides fully enclosed enclosures, reduces sound, light and dust pollution caused by engineering construction, and prevents high-altitude falling.

Background technique

Building construction envelope technology is generally combined with formwork construction technology. In multi-storey and high-rise buildings, floor-to-ceiling scaffolding and pick-up scaffolding are commonly used to form an enclosure system with dense mesh.

In the construction of high-rise and ultra-high-rise buildings, traditional formwork construction technologies, such as electric scaffolding and hydraulic climbing formwork systems, mostly use green mesh or steel wire mesh for the enclosure, and there are few precedents for fully enclosed enclosures. The traditional formwork system is difficult to meet the requirements of fully enclosed construction.

Among them, as shown in Figure 1, the main structure of the electric scaffold adopts circular tube members. Except for the connection of the bottom truss 17 on the bottom layer, the members of the other layers are connected at right angles, and no space truss system is formed. Therefore, the integrity and rigidity are relatively low. weak. Due to defects such as weak structural rigidity, it is difficult to resist huge wind loads under the condition of fully enclosed enclosure, and eventually structural damage occurs, which cannot meet the construction requirements of super high-rise buildings.

Among them, as shown in Figure 2, the hydraulic climbing formwork system includes a construction operation frame 1, an equipment operation frame 2, and the like. The main components of the construction operation frame 1 are connected at right angles, and its main operation platform 18 is shown in Figure 2. Since the space truss-type main platform and the bowstring truss are not used, its integrity is poor, and it is also unable to resist huge wind loads and cannot meet the requirements. Construction requirements for super high-rise buildings. In addition, due to the limitation of the beam height, the traditional hydraulic climbing formwork system cannot set its embedded points and support points on the concrete beam, so it is difficult to apply it in the frame structure.

The use of dust-tight fully enclosed enclosures (wind-shielding coefficient of 1.0) for the formwork system means that the wind load that plays a leading role in the structural force will increase to more than three times that of the usual situation (wind-shielding coefficient of 0.3), which means It is a fundamental change to the design of the formwork system. The traditional formwork system cannot meet the working requirements in a fully enclosed environment. Moreover, the research on traditional formwork systems is all about how to reduce the impact of wind load, which is just the opposite of the actual requirements.

The traditional climbing frame system can not meet the requirements of fully enclosed construction. The main reason is that the height of the cantilever section is too high, which causes the frame body of the existing electric scaffold or the frame body in the existing hydraulic climbing formwork system to be under the action of wind load. to yield.

However, there are very few theoretical and construction technology researches on the fully enclosed construction of the formwork system, and the traditional formwork system cannot meet the work requirements in a fully enclosed environment. Therefore, it is necessary to develop and innovate on the basis of the original formwork system, and develop a new structural system to meet the practical requirements of fully enclosed construction.

Therefore, how to provide a bowstring truss type fully enclosed hydraulic climbing formwork system with strong integrity and capable of resisting huge wind load is a technical problem to be solved urgently by those skilled in the art.
