A semi-automatic deviation correction and reset device for wooden frame

Abstract

A timber frame semi-automatic inclination adjustment resetting device is provided with a box base, a machine body column, a counterforce frame, a pulley device, a cross arm, a synchronous hydraulic jacking device, a double-acting hydraulic oil cylinder and a mechanical hoop. A hydraulic pump station is arranged in the box base, and the machine body column and the counterforce frame are fixed on the box base. The top of the machine body column is connected with the middle of the cross arm through a cross-shaped hinge. The double-acting hydraulic oil cylinder is arranged at the front end of the cross arm, and a piston rod of the double-acting hydraulic oil cylinder stretches out of the cross arm. The piston rod of the double-acting hydraulic oil cylinder is connected with the mechanical hoop through a cylinder pin. The rear end of the cross arm is hinged to a pulley in the pulley device. The pulley can horizontally move in a plane of the pulley device at will. The synchronous hydraulic jacking device is arranged on the inner side of the counterforce frame and used for controlling lifting of the pulley device. The hydraulic pump station is connected with the double-acting hydraulic oil cylinder and the synchronous hydraulic jacking device through oil delivery pipelines respectively. The timber frame semi-automatic inclination adjustment resetting device is used for achieving automatic and precise control over inclination adjustment of an ancient architecture timber structure column grid, and timber architectures are repaired and protected better.

Description

Technical field [0001] The invention relates to the research of a technology and device for correcting and resetting a crooked wooden frame. Background technique [0002] my country is one of the first countries to apply wood structure, and in the process of development, it gradually integrated the architectural art and the wood frame system to become an important part of the splendid Chinese culture. However, due to the influence of the external environment, adverse changes in material properties and other influencing factors, the crooked flash deformation of wooden frames is an unavoidable problem for almost all wooden buildings. At this stage, there are two major shortcomings in the tension support reset tool based on noose and jack: (1) The magnitude of the force system applied during correction is unknown and blind, and the phenomenon of "strong pulling and hard pulling" occurs from time to time; (2) The application process of the resetting force is uncontrollable, and it r...

Problems solved by technology

However, due to external environmental effects, unfavorable changes in material properties and other influencing factors, the crooked and flashing deformation of wooden frames is an unavoidable problem for almost all wooden structures.

At this stage, there are two major defects in the tensioning and jacking reset tools based on nooses and jacks: (1) The magnitude of the force system applied during deviation correction is unknown, which is blind, and the phenomenon of "forced pulling and pulling" occurs from time to time; (2) The application process of the reset force system is uncontrollable, and it relies too much on the visual judgment and operating experience of the construction personnel

These two defects can easily cause potential safety hazards in the process of correcting and resetting the timber frame: overloading, re-damage of the structure and even the overturning of the timber frame
