Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing:

[0025] Such as image 3 As shown, an electric hoist 7 and a hydraulic pump station 15 with a proportional pressure divider valve are arranged in the box body 1, ground support 2 is arranged around the box body 1, and a rigid connection is adopted between the ground support 2 and the box body 1 to prevent the present invention from Said device overturns due to excessive reaction force when carrying out the tensioning and supporting operation. The upper part of the box body 1 is equipped with a circular bearing platform 3, and the bottom of the circular bearing platform 3 is equipped with a slewing bearing. The circular bearing platform 3 can realize full-angle rotation in the horizontal plane, and the motor connected to it provides power, which is convenient for construction. Adjustment of the direction of correction and reset. The mechanical arm (vertical arm 4 and cross ...

Abstract

The invention provides a historic building slanting timber frame tensioning jacking resetting device which comprises a box body, a ground support, a round bearing table, mechanism arms composed of a vertical arm and a cross arm, a linear displacement amplifying device and an electric winch, an auxiliary jack, a power jack, a universal joint and a variable hoop which are arranged in the box body. A jacking system composed of a hydraulic pump station with a proportional pressure dividing valve and a large-stroke jack and a tensioning system composed of the electric winch, a steel strand and the linear displacement amplifying device are utilized to conduct tensioning and jacking resetting operation on a historic building slanting timber frame. Force transfer condition between the back shore system and the timber frame to be repaired is effectively improved through the universal joint and the variable hoop to achieve steering of a correction force system, secondary stress is greatly reduced in the correction, stress performance of a column head is improved, the column head is protected, and secondary damage caused by concentrated stress caused by the fact that the force system directly acts on the column head in the correction is avoided.

Description

technical field [0001] The invention relates to a device for repairing ancient building structures, in particular to a device for restoring crooked wooden frames of ancient buildings under tension and backing. Background technique [0002] Ancient wooden buildings occupy an absolute mainstream and dominant position in the development of Chinese architecture, reflecting the core connotation of ancient Chinese architecture and culture. However, due to the age, after material degradation, earthquake, corrosion and other external effects, the components will inevitably be damaged and deformed, and the crooked flash deformation has become the main disease of ancient wooden frame buildings, and the safety of the structure is threatened. From the Yingxian wooden pagodas built in the Song and Liao dynasties to the palace halls in the Ming and Qing dynasties, most of them have different degrees of crookedness. Therefore, it is one of the important tasks in the restoration and reinfo...
