Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and particularly relates to a method for installing an extra-long curtain wall keel. Background Art

[0002] Curtain wall panels are a rapidly emerging building technology. They typically combine aluminum alloy frames, glass, spacers, insulation, shock-absorbing and waterproof materials, and decorative fabrics into curtain wall units with additional iron fittings in the factory. After the columns are hoisted, the unit glass curtain wall is hoisted and installed, requiring a crane for the entire process. Due to the design of the building's height, the curtain wall panels are large in size, with the steel columns being even longer. Therefore, during the hoisting of the extra-long and thin columns, the columns are prone to significant deformation during the process of being hoisted from horizontal to vertical, and their bottoms are easily damaged by collision with the ground, affecting the installation of the columns and the subsequent curtain wall panels. Summary of the Invention

[0003] In view of this, the present invention discloses a method for installing an extra-long curtain wall keel, which aims to solve the problem that during the hoisting process of an extra-long column, the bottom of the column is easily damaged by collision with the ground during the process of lifting the column from horizontal to vertical, thereby affecting the installation of the column.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] A method for installing an extra-long curtain wall keel comprises the following steps:

[0006] 1) Column Preparation: Install auxiliary equipment that can move relative to the ground; install the connecting support component on the column and place the end of the connecting support component on the auxiliary equipment so that the end of the column can deflect relative to the auxiliary equipment; install the guide rail on the ground and install the vehicle body on the guide rail; connect the crane's traction rope to the front end of the connecting support component, with the connection point located in the upper area of the column;

[0007] 2) Hoisting the column: Start the crane and lift the column from a horizontal state to a vertical device. During the entire process, the end of the column is supported by auxiliary equipment, and the auxiliary equipment moves with the end of the column to the bottom of the column to ensure that the column is in a vertical state. After the connecting support components and the auxiliary equipment are disassembled, the column is hoisted to the installation location of the building using a crane while maintaining the vertical state. After the column is installed, the connecting support components and the traction rope are removed.

[0008] 3) Install the curtain wall unit: After the columns are installed, use a crane to lift the curtain wall unit onto the columns for installation.

[0009] Furthermore, the auxiliary equipment includes a guide rail fixed on the ground, and the guide rail faces the crane, a car body is provided on the guide rail, and an adjustment groove horizontally and perpendicular to the guide rail is opened on the car body, a support is slidably connected to the adjustment groove, and a connecting seat is hinged at the top of the support; it also includes a connecting support component detachably mounted on the column, the connecting support component extends from the end of the column to the upper half of the column, and the end of the connecting support component is detachably connected to the connecting seat, and the front end of the connecting support component is connected to the traction rope of the crane.

During the whole process, the connection between the column, the connecting support component and the connecting seat is used to make the vehicle body move with the movement of the end of the column, and the end of the column is always supported to prevent the end of the column from colliding with the ground and being damaged; the setting of the support and the guide rail enables the connecting seat to move in any horizontal direction with the end of the column; when the column is pulled to the vertical state, the connecting support component and the connecting seat are removed, and then the column is lifted to the installation position of the building by the crane.
