Self-balancing ancient building framework correcting and resetting device and method

Abstract

The invention discloses a self-balancing ancient building framework correcting and resetting device and method, and the device comprises fixing sleeves which sleeve the two ends of a cross beam, a pair of supporting brackets which are fixed below the cross beam and are connected with supporting columns, and a displacement control adjusting device which is connected between a pair of fixing parts and can adjust the relative distance. Connecting parts are hinged between the fixing sleeves and a supporting device; the horizontal distance relative to the opposite cross beam is adjusted through the displacement control adjusting device, and creep bending of the cross beam is corrected by pulling the acting force of the connecting parts and the supporting device on the cross beam. Downward external force is applied to the two ends of the beam and upward external force is applied to the middle of the beam through component force of pulling force in the connecting parts and pressure in the supporting columns, downward creep bending of the cross beam is corrected, the cross beam is made to return to the straight state, and the device is high in efficiency and good in correction effect.

Description

technical field [0001] The invention belongs to the technical field of wooden structures, and in particular relates to a self-balancing device and method for correcting and restoring the skeleton of an ancient building. Background technique [0002] As a building material, wood has the characteristics of convenient materials, simple construction process and fast construction speed. However, due to the characteristics of the wood itself, after a period of use, the beams in the structure will have a certain degree of creep under the action of load, and the beams will bend and sink downward under the action of creep, so that The columns supported on it will also sink, so that the roof at the connection with the columns will lose its support, and the building will collapse. [0003] The beams and columns in wooden structures are mostly connected by mortise and tenon joints. In the existing technology, the common correction method for the creep deformation of wooden beams is to ...

Problems solved by technology

However, due to the characteristics of the wood itself, after a period of use, the beams in the structure will have a certain degree of creep under the action of load, and the beams will bend and sink downward under the action of creep, so that The columns supported on it will also sink, causing the roof at the connection with the columns to lose its support, and the building is in danger of collapsing

[0003] The beams and columns in wooden structures are mostly connected by mortise and tenon joints. In the existing technology, the common correction method for the creep deformation of wooden beams is to remove the beams and place the bent ends of the downwardly bent beams upside down. , and strengthen the beams, but this method is not suitable for beams and columns connected with asymmetrical mortise and tenon joints. For structures with asymmetrical mortise and tenon joints, it is necessary to use external forces to correct and reset the bent beams, and after correction Reinforce the beams

In the prior art, the method of rectifying and resetting the bent beam with the help of external force includes methods such as landing on the roof and resetting the method, and there is a common problem that it needs to be installed on the ground, which affects the normal traffic on the ground
