Attached support structure

Abstract

The invention relates to an attached support structure which consists of a guide seat and an attached support. An outer cylinder of the attached support is movably sheathed on an inner cylinder; a regulating nut is fixedly arranged in the inner cylinder, a regulating screw rod is arranged in the outer cylinder, the regulating screw rod is connected with the regulating nut through a thread, and a driving mechanism for leading the regulating screw rod to rotate is arranged on the regulating screw rod. The guide seat comprises a guide seat body, a lifting pull rod and a one-way pawl mechanism. The one-way pawl mechanism comprises an anti-fall block, a sliding cylinder and a reset tension spring, wherein, the anti-fall block is mounted on the guide seat body through a support pin shaft, a shift fork is arranged on the outer wall of the sliding cylinder, and a sliding pin on the anti-fall block is positioned in a shift fork notch; and one end of the rest tension spring is connected with the guide seat body, the other end is connected on the sliding cylinder by hanging, and the sliding cylinder and the lifting pull rod form the sliding pair connection. On the one hand, the attached support structure realizes the stepless regulation of the connection distance between a frame body and the surface of an outer wall of a building, on the other hand, the attached support structure can realize the full-automatic two-way anti-fall of the frame body by utilizing loads during lifting.

Description

technical field [0001] The invention relates to an attached lifting scaffold for building construction, in particular to an attached supporting structure of the attached lifting scaffold. The attached support structure can realize the stepless adjustment of the connection distance between the frame body and the outer wall of the building. At the same time, it can stabilize the frame body to prevent the frame body from tilting inside and outside, and can prevent the frame body from falling due to abnormal reasons under any working conditions. A fully automatic fall prevention device. Background technique [0002] At present, in the construction of high-rise buildings, especially super high-rise buildings, attached lifting scaffolds have been widely used. The attached lifting scaffold is mainly composed of two parts: the frame structure and the lifting control system; the frame structure is composed of the vertical main frame assembly, the horizontal truss, the attached suppo...

AI Technical Summary

Problems solved by technology

The anti-drop device of the frame is usually unable to effectively prevent the fall of the frame due to the complex construction environment, such as the influence of water, sand, concrete, and design defects in the structural function itself, and the reliability of the anti-fall of the frame , to determine whether the frame is safe when running up and down

[0004] There are mainly two types of anti-falling methods commonly used for attached support scaffolds in principle, friction type and one-way ratchet pawl type. Both methods have some shortcomings, mainly because they cannot adapt well to the complex construction site environment The regulations and reliability of the anti-fall distance cannot meet the national mandatory standards, and it is difficult to realize multi-point anti-fall at the same time, and the structure of the anti-fall trigger device is complex, and a lot of preparation work needs to be done before the frame is lowered. The process is cumbersome and error-prone. The device is exposed to the outside and is susceptible to failure due to the influence of the working environment. The effectiveness of the mechanism is poor, which is the main cause of major safety accidents caused by the fall of the frame

[0005] At the same time, in the existing technology, the attached support structure generally adopts a fixed size, and its length determines the installation distance between the frame and the wall, and the specification requires that the distance between the wall and the frame is less than 300mm from the wall, and the shape of the building is often varied. Specifically, it is difficult for fixed-size attached supports to meet the needs of complex construction conditions. For example, when a building has awning boards and structural beams and columns with convex and concave, parallel iron or extended attached supports are generally used to connect with the building wall. connect

This kind of structure is bulky, cumbersome to install, high in cost, difficult to grasp the distance control accuracy, easy to generate large installation stress and overturning moment, and cannot guarantee the verticality of the vertical main frame of the frame body, resulting in deformation of the vertical main frame guide rails. Increase the lifting force, there is a great potential safety hazard
