Description

Technical Field

[0001] The invention relates to the technical field of corridor construction, and in particular to a hoisting method. Background Art

[0002] Existing high-rise buildings are all equipped with corridors, which can not only strengthen the connection between multiple towers, but also serve as a safe passage. In order to improve the aesthetics of the corridor, a special-shaped curtain wall structure is arranged at the bottom of the corridor in the prior art, that is, along the extension length direction of the corridor, the height of the special-shaped curtain wall structure away from the bottom wall of the corridor is different, and the bottom wall of the special-shaped curtain wall structure is arranged in an inclined shape as a whole.

[0003] During construction, if the construction method of hoisting the special-shaped curtain wall structure after the corridor is installed is adopted, since the corridor is usually set relatively high, this will inevitably increase the number of high-altitude hoisting, greatly increasing the construction risk; and if the construction method of hoisting the corridor and the special-shaped curtain wall structure together after fixing them is adopted, then when the special-shaped curtain wall structure is fixed to the corridor on the ground, in order to ensure that the corridor and the special-shaped curtain wall structure are firmly installed and prevent them from falling off during high-altitude hoisting and causing danger, it is necessary to make a tire frame compatible with the special-shaped curtain wall structure for support, resulting in reduced construction efficiency. Summary of the invention

[0004] In view of this, the present invention provides a hoisting method to solve the problems of high construction risk and low construction efficiency when the shape of the special-shaped curtain wall structure is relatively complex.

[0005] The present invention provides a hoisting method for hoisting a first workpiece, wherein a second workpiece is disposed at the bottom of the first workpiece, and the distance between the bottom wall of the second workpiece and the bottom wall of the first workpiece is different along a direction perpendicular to the extension length of the first workpiece, comprising:

[0006] hoisting the first workpiece to a preset height, wherein the preset height is greater than a maximum distance between a bottom wall of the second workpiece and a bottom wall of the first workpiece;

[0007] installing the second workpiece on the bottom of the first workpiece;

[0008] The first workpiece is hoisted to an installation height, and the installation height is greater than the preset height.

[0009] Beneficial effects: By setting the second workpiece at the bottom of the first workpiece before hoisting the first workpiece to the installation height, the first workpiece and the second workpiece can be hoisted synchronously, thereby reducing the number of high-altitude hoisting times to improve construction efficiency and reduce the risk of high-altitude operations; by setting the bottom wall of the second workpiece to have a different distance from the bottom wall of the first workpiece, the aesthetics of the second workpiece can be improved; by hoisting the first workpiece to a preset height and then installing the second workpiece at the bottom of the first workpiece, the second workpiece can be installed in the air to avoid the influence of the shape of the bottom wall of the second workpiece on the installation, and thus there is no need to support the second workpiece, reducing the use of supporting devices during installation, reducing construction costs, and improving construction efficiency.

[0010] In an optional embodiment, the second workpiece includes at least a first decorative component and a second decorative component, the maximum distance between the bottom wall of the second decorative component and the bottom wall of the first workpiece is greater than the maximum distance between the bottom wall of the first decorative component and the bottom wall of the first workpiece, and the first workpiece is hoisted to a preset height and the second workpiece is installed on the bottom of the first workpiece, comprising:

[0011] hoisting the first workpiece to a first preset height, wherein the first preset height is greater than a maximum distance between a bottom wall of the first decorative component and a bottom wall of the first workpiece;

[0012] installing the first decorative component on the bottom of the first workpiece;

[0013] Hoisting the first workpiece to a second preset height, where the second preset height is greater than the maximum distance between the bottom wall of the second decorative component and the bottom wall of the first workpiece;

[0014] The second decoration component is mounted on the bottom of the first workpiece.

[0015] Beneficial effect: Since the second workpiece includes at least the first decorative component and the second decorative component, the portion with a larger distance difference between the bottom wall of the second workpiece and the bottom wall of the first workpiece can be divided, and the portion with a smaller distance difference becomes a whole. Therefore, when hoisting the first workpiece, the hoisting height of the first workpiece can be determined according to the size of each part in the second workpiece, so that the height of the first workpiece corresponds to the size of each part during installation, and the installation is more convenient.

[0016] In an optional embodiment, the second workpiece includes at least a third decorative component, and the maximum distance between the bottom wall of the third decorative component and the bottom wall of the first workpiece is greater than the maximum distance between the bottom wall of the second decorative component and the bottom wall of the first workpiece. Before hoisting the first workpiece to the installation height, the method includes:

[0017] hoisting the first workpiece to a third preset height, wherein the third preset height is greater than a maximum distance between a bottom wall of the third decorative component and a bottom wall of the first workpiece;

[0018] The third decoration component is mounted on the bottom of the first workpiece.

[0019] Beneficial effect: By providing the third decorative component, the aesthetics of the second workpiece can be improved.

[0020] In an optional embodiment, before hoisting the first workpiece to a preset height, the method includes:

[0021] Assemble the first workpiece on the ground.

[0025] Assemble the first decorative component, the second decorative component and the third decorative component on the ground.

[0026] Beneficial effect: By hoisting the first workpiece to a specified height, assembly space for the first decorative component, the second decorative component and the third decorative component can be reserved, and then they can be assembled on the ground below the first workpiece, which can reduce space occupancy and reduce construction costs.

[0027] In an optional embodiment, the cross-sections of the first decorative component, the second decorative component and the third decorative component are all U-shaped. After the first decorative component, the second decorative component and the third decorative component are assembled on the ground, the following steps are included:

[0028] A first support member is installed in the "U"-shaped opening of the first decorative component, a second support member is installed in the "U"-shaped opening of the second decorative component, and a third support member is installed in the "U"-shaped opening of the third decorative component.

[0029] Beneficial effect: By setting the first decorative component, the second decorative component and the third decorative component as a "U"-shaped structure, the lateral force of the wind load on the first workpiece can be reduced; by providing the first support member, the second support member and the third support member, the first decorative component, the second decorative component and the third decorative component can be reinforced, thereby improving the structural strength of the first decorative component, the second decorative component and the third decorative component, and preventing the first decorative component, the second decorative component and the third decorative component from being deformed during the lifting and installation process, thereby affecting the use effect.

[0032] Beneficial effect: By setting the first fixing member and the second fixing member, a position for fixed installation can be provided for the first decorative component, the second decorative component and the third decorative component, and the connection is tight and not easy to fall during high-altitude hoisting.

[0033] In an optional embodiment, the first decoration component, the second decoration component and the third decoration component are all installed between the first fixing member and the second fixing member.

[0034] In an optional embodiment, the first decoration component, the second decoration component and the third decoration component are arranged in sequence along the extension length direction of the first workpiece.

[0035] In an optional embodiment, the first decoration component, the second decoration component and the third decoration component are all surrounded by at least two decoration modules.

[0036] Beneficial effect: By enclosing the first decorative component by at least two decorative modules, the weight of the first decorative component can be dispersed, thereby facilitating transportation and lifting; by enclosing the second decorative component by at least two decorative modules, the weight of the second decorative component can be dispersed, thereby facilitating transportation and lifting; by enclosing the third decorative component by at least two decorative modules, the weight of the third decorative component can be dispersed, thereby facilitating transportation and lifting.
