Description

Technical Field

[0001] The present invention relates to the technical field of inclined climbing construction methods for scaffolding, and particularly to an inclined climbing construction method for a fully steel attached lifting scaffolding with anti-overturning function. Background Art

[0002] In modern construction, scaffolding, as an important construction equipment, is widely used in various construction projects. The fully steel attached lifting scaffolding has been increasingly applied in high-rise building construction due to its advantages such as reusable, material and labor saving. However, during the climbing process of the scaffolding, due to various factors such as construction loads, wind forces, and irregular building structures, there is a risk of overturning of the scaffolding, which seriously threatens the lives of construction workers and the project progress. Especially in the construction of some buildings with inclined angles, the traditional scaffolding climbing methods are difficult to meet the construction requirements and are prone to unstable situations such as inclination and shaking.

[0003] At present, there are many deficiencies in the existing scaffolding construction methods in dealing with these problems. For example, the unreasonable setting of the lifting units leads to uneven lifting forces, resulting in uneven stress of the scaffolding during the climbing process and increasing the possibility of overturning; the setting of the top tie of the frame body is not standardized, and it cannot effectively restrain the shaking of the frame body; when dealing with the intersection of the construction elevator and the scaffolding and the connection between the unloading platform and the scaffolding, there are lack of effective protection and connection measures, posing great safety hazards; for the attachment method of the machine positions, if the selection is improper or the strength check calculation is insufficient, it may lead to insecure connection between the scaffolding and the building, causing serious accidents. Therefore, it is of great practical significance to develop a safe, reliable, efficient and practical inclined climbing construction method for a fully steel attached lifting scaffolding with anti-overturning function. Summary of the Invention

[0004] The purpose of the present invention is to provide an inclined climbing construction method for a fully steel attached lifting scaffolding with anti-overturning function to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An inclined climbing construction method for a fully steel attached lifting scaffolding with anti-overturning function, including the following steps: setting lifting units, determining the models, quantities and installation positions of the lifting units according to the load, climbing height and inclination angle of the scaffolding to ensure uniform distribution of the lifting forces; Pre-adjusting the top tie of the frame body, checking and pre-adjusting the tie between the top of the frame body and the building structure before the scaffolding climbs to ensure firm tie and appropriate restraint stiffness; Adjusting the inward inclination of the frame body, monitoring the inclination state of the frame body in real time during the climbing process, and when there is an inward inclination trend, adjusting by adjusting the lifting speed of the lifting unit or using auxiliary support devices to keep the frame body vertical; After the scaffolding enters the normal state, carry out the treatment of the position of the unloading platform. According to the size, load-bearing requirements of the unloading platform and the structural characteristics of the scaffolding, determine the connection method and reinforcement measures between the unloading platform and the scaffolding; Treatment of the construction elevator position. For the intersection part between the construction elevator and the scaffolding, design special protection and connection structures to ensure the safe operation of the construction elevator and not affect the climbing of the scaffolding; Elevation layout of the scaffolding. According to the shape of the building facade and construction requirements, reasonably arrange the vertical poles, horizontal bars and diagonal braces of the scaffolding to form a stable elevation structure; Setting of the attachment method of the lifting position. According to the building structure type and load-bearing capacity, select the connection with wall-through bolts and check the strength of the attachment points.

[0006] Furthermore, in the step of setting the lifting unit, the lifting unit adopts an electric hoist or a hydraulic jack with intelligent control.

[0007] Furthermore, in the step of pre-adjusting the tie at the top of the scaffolding, the tie adopts a rigid tie rod or a steel wire rope.

[0008] Furthermore, in the step of adjusting the inward inclination of the scaffolding, an inclination sensor is used to monitor the inclination angle of the scaffolding in real time.

[0009] Furthermore, in the step of treating the position of the unloading platform, a detachable rigid connection is set between the unloading platform and the scaffolding.

[0010] Furthermore, in the step of treating the position of the construction elevator, a double-layer protective shed is set between the construction elevator and the scaffolding.

[0011] Furthermore, in the step of elevation layout of the scaffolding, the setting angle of the diagonal brace is 45° - 60°, and it is continuously set along the entire length and height of the outer elevation of the scaffolding.

[0012] Furthermore, when the attachment method of the lifting position adopts wall-through bolts, the diameter of the wall-through bolts is not less than 20mm, and the material is not lower than grade 8.8.

[0013] Furthermore, when the attachment method of the lifting position adopts wall-through bolts, the number of attachment bolts for each lifting position is not less than 4.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. By reasonably setting measures such as the lifting unit, pre-adjusting the tie at the top of the scaffolding, and real-time monitoring and adjusting the inward inclination of the scaffolding, effectively prevent the scaffolding from tipping over during the climbing process, and ensure the life safety of construction workers. The protection and connection structures at the intersection of the construction elevator and the scaffolding and the reasonable setting of the unloading platform reduce the potential safety hazards during the construction process.

[0015] 2. The reasonable setting of the scissors braces in the elevation layout of the framework and the strict requirements for the attachment method of the lifting positions enable the scaffolding to form a stable structural system, which can better withstand the construction loads and the influence of the external environment, and improve the overall stability of the scaffolding. Detailed implementation method

[0016] The following further describes the implementation method of the present invention in detail in combination with embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0017] An anti-overturning full-steel attached lifting scaffolding inclined climbing construction method. Construction preparation: According to the load calculation results of the scaffolding, select a suitable type of intelligent control electric hoist as the lifting unit, and prepare the corresponding number of equipment. At the same time, check the performance indicators of the electric hoist to ensure its normal operation.

[0018] Prepare materials such as rigid tie rods, steel wires, and wall-piercing bolts to ensure that the specifications and quality of the materials meet the requirements. Conduct sampling inspection on the wall-piercing bolts to check parameters such as their diameter, material, and strength.

[0019] Install equipment such as inclination sensors and intelligent control systems, and conduct debugging to ensure that they can accurately monitor and control the climbing process of the scaffolding.

[0020] Set the lifting unit during the construction process: According to the climbing height and inclination angle of the scaffolding, install the electric hoist at a suitable position on the scaffolding, and conduct debugging through the intelligent control system to control the synchronous lifting error of the electric hoist within ±5 mm. During the installation process, ensure that the electric hoist is firmly fixed, and its installation position can meet the requirement of uniform distribution of the lifting force.

[0021] Pre-adjust the top tie of the framework: Before the scaffolding climbs, install rigid tie rods or steel wires according to the requirement of setting one tie every 3 steps. Adjust the length and angle of the tie to make its horizontal spacing not greater than 4 m, and ensure that the tie is firm. During the adjustment process, use a force-measuring tool to check the tension of the tie to ensure that it meets the design requirements.

[0022] Adjust the inward inclination of the framework: During the climbing process of the scaffolding, the inclination sensor real-time monitors the inclination angle of the framework. When the inclination angle exceeds ±3°, the intelligent control system automatically adjusts the lifting speed of the electric hoist to make the framework return to the vertical state. If the inclination angle is relatively large, an auxiliary support device can also be used for auxiliary adjustment.

[0023] Treatment of the position of the unloading platform: According to the size and load-bearing requirements of the unloading platform, determine the installation position of the unloading platform on the scaffolding. Use a detachable rigid connection method to firmly connect the unloading platform to the scaffolding, and set a load limit sign on the unloading platform. During the use process, strictly operate according to the load limit requirements to prevent overloading.

[0024] Treatment of the position of the construction elevator: At the intersection of the construction elevator and the scaffolding, install a double-layer protective shed. The width of the protective shed is set to 2.5 m and the length is set to 3 m. Install protective railings and close-mesh safety nets on both sides of the elevator door to ensure the safety of construction workers.

[0025] Arrangement of the facade of the framework: According to the design requirements, reasonably arrange the vertical poles, horizontal bars and diagonal braces of the scaffolding. The setting angle of the diagonal braces is controlled between 45° - 60°, and they are continuously set on the outer facade of the framework. During the arrangement process, ensure that the connections of all components are firm and meet the requirements of relevant specifications.

[0026] Setting of the attachment method at the machine position: According to the structural characteristics of the building, drill holes at the machine position to install wall-through bolts. The diameter of the wall-through bolts is 20 mm and the material is grade 8.8. Install 4 wall-through bolts at each machine position, and conduct a strength check on the attachment points to ensure that the load-bearing requirements are met. During the installation process, use a torque wrench to tighten the bolts according to the specified torque to ensure firm connection.

[0027] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better illustrate the principles of the invention and its practical application, and to enable those of ordinary skill in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.
