Description

Height-difference-adjustable double-layer operating platform for building main body and exterior decoration construction and installation method

technical field

The invention relates to an operating platform for building construction, in particular to a double-layer operating platform with adjustable height difference for building main body and exterior decoration construction and an installation method.

Background technique

Building construction is divided into two stages: main body construction and interior and exterior decoration construction. At present, the facilities for construction personnel to operate in the domestic construction process are relatively backward. 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, resulting in a waste of manpower and time and an increase in use costs.

Beijing Xingheren Construction Technology Co., Ltd. introduced the electric construction lifting platform from Spain, and provides one or more people to work on it 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, the lack of force transmission points of the column, and the poor rigidity lead to the limitation of the cantilever height above the last attachment point; in addition, the distance between the platform and the building is relatively large, and it is necessary to install an extended platform to meet the construction requirements, resulting in an increase in the platform's own weight; As shown in Figure 3: the cantilever height is just over 2 stories high 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 the 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.

Contents of the invention

In order to overcome the above-mentioned technical deficiencies, the present invention provides a two-layer operating platform with adjustable height difference for building main body and exterior decoration construction and an installation method.

The present invention adopts following measures to realize:

A double-layer operating platform with adjustable height difference for building main body and exterior decoration construction, including a column fixed to the building with a wall frame, a sleeve frame that can move up and down along the column, a main platform connected to the sleeve frame and through A connecting boom with a height adjustment device is suspended from the sub-platform below the main platform.

In the preferred solution of the above-mentioned operating platform, the four sides of the sleeve frame are hooped on the column, and the side of the sleeve frame close to the building is provided with openings. The upper and lower ends of the sleeve frame are in contact with the four main legs of the column with multiple rollers.

In the preferred solution of the above-mentioned operating platform, a U-shaped reinforcing ring beam is arranged on the position where the connecting platform and the rollers are arranged on the sleeve frame.

In the preferred solution of the above-mentioned operating platform, in the preferred solution of the above-mentioned operating platform, two rollers are used to contact the main limbs of the column at the four corners of the upper and lower ends of the sleeve frame.

In the preferred solution of the above-mentioned operation platform, the height adjustment device is a plurality of pipe fittings nested together.

A method for installing a height-difference-adjustable double-layer operating platform for the building main body and exterior decoration construction, comprising the following steps:

1) Install the column: according to the height of use, use the attached wall frame to connect the column with the building;

2) Install the sleeve frame: use rollers to contact the sleeve frame with the four main limbs of the column;

3) Install the main and auxiliary operating platforms: install the main platform on the column, and install a height adjustment device on the connecting boom. According to the height of the building, adjust the distance between the main platform and the auxiliary platform before installing the auxiliary platform. Rods suspend the secondary platform under the main platform;

4) After installation, it can be put into use, and the set frame drives the main platform and the auxiliary platform to run up and down.

The present invention mainly has following characteristics:

1) It is not only suitable for the construction of the main body of the building, but also can be applied to the operation of exterior decoration construction at the same time;

2) The main platform and the auxiliary platform set under the main platform are suitable for construction personnel to operate on the upper and lower construction work surfaces at the same time;

3) The structure of a sub-platform suspended on the main platform is adopted, the force is more reasonable, the structure is lighter, and the safety monitoring system is more concise and reliable;

4) The height difference between the main platform and the auxiliary platform can be adjusted according to different floor spacings;

5) The bracket and the column are hooped together, and there are openings, which can avoid interference with the wall bracket, and make the operating platform closer to the building, which is convenient for construction, and there is no need to install an extension platform.
