Description

Erection method of external protective scaffolding for buildings with twisted facades

technical field

The invention belongs to the technical field of building external protective scaffolding construction, in particular to a method for erecting external protective scaffolding of buildings with twisted facades.

Background technique

In the process of building construction, external protective scaffolding is generally set up to protect the construction site, and it is also convenient for workers to carry out construction operations on the external protective scaffolding. Existing external protective scaffolds mainly include floor type, cantilever type and climbing type. For buildings with a relatively high height, it is more economical to use the climbing type and the cantilever type, which is conducive to saving costs.

Contents of the invention

The object of the present invention is to provide a method for erecting an external protective scaffold of a building with a twisted facade, so as to solve the problem that the external protective scaffold with a twisted facade is inconvenient to erect.

In order to achieve the above object, the basic solution of the present invention provides a method for erecting an outer protective scaffolding of a building with a twisted facade, comprising the following steps:

Step A: Install and fix the attachment support device on the vertical facade of the building, set the support frame below the attachment support device, install and fix the main frame with guide rails on the support frame, and make the guide rails of the main frame and the attachment support The device is slidingly connected, and a climbing scaffold frame is set up between adjacent main frames; a cantilevered scaffold is set up on the twisted facade of the building. The steps are: install a fixed cantilevered cantilever on the top of the floor. A cantilevered scaffold body is erected on the pole, and the cantilevered scaffold is connected to the building with wall pieces;

Step B: detachably connect the connecting rod between the climbing scaffold body and the cantilevered scaffold body;

Step C: connecting the closed plate at the bottom of the cantilevered scaffold body and the climbing scaffold body;

Step D: The connection between the outer side of the climbing scaffold body and the outer side of the cantilevered scaffolding is used to fix and close the net window.

The principle and beneficial effects of this basic scheme are: by setting climbing scaffolding at the vertical facade of the building, it is beneficial to reduce the protection cost of the vertical facade of the building; setting cantilevered scaffolding at the twisted facade, Compared with the use of climbing scaffolding, it reduces the difficulty of erection and facilitates construction operations. By setting the connecting rod in step B, the climbing scaffold and the cantilevered scaffold are connected as a whole, which is conducive to improving the stability of the entire outer protective scaffold. By setting the closing plate in step C, materials are prevented from falling from the bottom of the outer protective scaffold, and safety is enhanced. By setting the closed net window in step D, it is beneficial to protect the outer facade of the external protective scaffolding. By using both climbing scaffolding and cantilevered scaffolding on buildings with twisted facades, the cost of the external protective scaffolding of the building is kept at a low level, and the difficulty of erecting the external protective scaffolding is reduced. .

Further, the cantilevered scaffolding is erected in sections in the vertical direction of the twisted facade. It is erected in sections, so that the cantilevered scaffolding can be easily adjusted according to the twisting direction of the twisted facade, which is conducive to reducing the difficulty of erection.

Further, a stay rope is arranged between the cantilevered end of the cantilever of the cantilevered scaffold and the building components above it. By arranging the stay rope, it is beneficial to increase the load-carrying capacity of the cantilever and improve the stability of the frame.

By setting the pressing plate with the pole seat, it is convenient to install the pole of the cantilevered scaffold through the pole seat, and the installation efficiency is improved.

Furthermore, a flap for closing the gap from the wall is provided between the climbing scaffold body and the floor platform of the building. By setting the sealing plate, the material on the frame body can be prevented from falling from high altitude through the wall gap between the frame body and the floor platform of the building, which is beneficial to ensure the safety under the frame body.

Further, the operating layers of the cantilevered scaffold body and the climbing scaffold body are laid with steel mesh sheets, and the steel mesh sheets are detachably connected to the frame bodies. By laying steel mesh, the operation layer has a larger supporting area, which is convenient for workers to work on the steel mesh.

Further, in the step D, a net window connector is detachably connected to the closed net window, and a net window connecting rod is detachably connected to the climbing scaffold body and the cantilevered scaffold body respectively, and the net window connector and the net The window connecting rod is detachably connected. By setting the net window connecting piece, it is convenient to connect the closed net window with the frame body; by setting the net window connecting rod and the net window connecting piece, it is convenient to adjust the position of the net window connecting rod and the net window connecting piece to achieve the correctness of the net window. The purpose of adjusting the connection position of the window is to facilitate the adjustment of the position of the net window.

Further, the net window connector includes an annular buckle part, a positioning block is fixedly connected to the buckle part along the tangential direction, and a connecting piece is fixedly connected to the side of the positioning block away from the buckle part, and the connecting piece is far away from the end of the positioning block It is the connecting end connected with the net window, the central line of the connecting end is perpendicular to the positioning block and is located outside the outline of the buckle. The connecting end of the connecting piece is perpendicular to the positioning block. When the positioning block is attached to the vertical pole, it can ensure that the connecting end of the connecting piece is in a horizontal state, so as to facilitate the connection between the connecting end and the closed net window; The center line is arranged on the outside of the outline of the buckle, so that when the net window connector is on the net window connecting rod that is misplaced up and down, the connecting ends can be at the same horizontal position, thereby ensuring that the net window is at the same level.

Furthermore, both the climbing scaffold body and the cantilevered scaffold body can be detachably connected with ladders. By setting the ladder, it is convenient for workers to move vertically on the frame.
