Description

Multi-storey lifting platform system for building construction

technical field

The invention relates to a multi-layer lifting platform suitable for building main body and exterior decoration construction, a matching lifting system and a working method thereof.

Background technique

Building construction is divided into two stages: main construction and interior and exterior decoration construction. At present, in the main construction stage, floor-to-ceiling scaffolding is generally used for multi-storey and low-rise buildings, and cantilevered scaffolding is generally used for high-rise buildings. Attached lifting scaffolding is only partially used in the construction of high-rise buildings above 50 meters due to its complicated erection, and it cannot be applied to the construction process of building exterior decoration due to the complicated lifting operation and the inability to lift in sections. After the main body construction is capped, the above-mentioned scaffolding needs to be dismantled, and then the hanging basket for high-altitude operation is used for building exterior decoration construction. Therefore, there is still no safe and reliable operating facility or equipment that can be suitable for main body construction and can be applied to building exterior decoration construction at present in China. The construction process requires the installation and use of two different operating facilities, which is costly and inefficient.

Some companies have introduced electric construction lifting platforms from abroad, and provide one or more people to work on them at the same time. As shown in Figure 1: the platform structure adopts a single-layer platform, and construction personnel can only operate on one level of the building; as shown in Figure 2: the sleeve frame connecting the operation platform and running along the column uses 6 rollers and only 2 of the column The contact of the main limbs, few force transmission points of the column, and poor rigidity lead to the limitation of the cantilever height above the last attachment point; as shown in Figure 3: the cantilever height just exceeds the height of 2 floors of the building. Generally, the distance between the operation platform and the wall frame is 2 storeys high. During the construction of the main body of the building, especially the main structure of concrete, it needs a certain amount of time for maintenance. If the cantilever height of the operating platform just exceeds the height of two floors of the building, it is impossible to install a wall frame on the main structure that has not reached the maintenance period. Therefore, this type of electric construction lifting platform cannot meet the requirements of the main construction stage. At present, it can only be used Decorate construction outside the building. At the same time, due to the high cost, it is economically unable to compete with the hanging basket for high-altitude operations when used alone in the building exterior decoration stage, so it is rarely used in projects at present.

At present, in building construction, construction elevators and tower cranes are mainly used to transport operators and required materials. In the main construction stage, personnel and materials need to be transported to the building or the working surface first, and then transported to the scaffold or operation platform through secondary transportation; in the external decoration stage, the general tower crane has been dismantled, and the transportation of personnel and materials can only Relying on construction elevators, especially the materials used for exterior decoration, needs to enter the interior of the building first, and then be transported to the scaffolding or operating platform for the second time, which seriously affects the construction efficiency, increases the labor intensity of workers, and poses safety hazards.
