Description

Technical Field

[0001] The utility model relates to the technical field of ancient building restoration, in particular to a beam and column node reinforcement structure of an ancient building. Background Art

[0002] Currently, during the conservation and repair of large timber structures in ancient buildings, the phenomenon of beam pullout and tenon damage is very prominent, especially at the joints between single-step beams and columns on the mountain faces of ancient buildings. This is because the uneven settlement of the foundation of the ancient buildings or the influence of horizontal external forces have caused the tenons between the cantilever beams, the end beams, and the columns to be half-tenons, which are extremely easy to pull out. Pulling out the tenons will weaken the overall stability of the timber structure. Tenons that are too large can easily cause the timber structure to seriously tilt and skew. In addition, when the tenons are inserted into the mortise, under the influence of long-term external forces, they may be damaged by the compression of the mortise. Or, due to the compression and deformation of the mortise, the tenons themselves may be reduced in cross-section and cause sinking, thus weakening the connection between beams and columns. In particular, the large timber structures of ancient buildings in southern my country mostly use through-beam structures, and the beam and beam connections are all half-tenoned.

[0003] A Chinese utility model patent (authorization announcement number CN221298676U) discloses a reinforcement structure for the joints of beams and columns of ancient buildings, comprising a clamping assembly, including a mounting shell, a hinge, a pressing module, and a buckle module. The mounting shell is movably arranged on the outside of the column through the hinge, the pressing module is threadedly connected and fitted to the front end of the mounting shell, and the buckle module is buckled and fitted to the side of the mounting shell. The stabilizing assembly comprises a sliding module, a rotating module, and a supporting module. The three sliding modules are respectively slidably arranged on the side of the mounting shell, the rotating module is threadedly connected and fitted to the bottom end of the sliding module, the supporting module is movably fitted to the upper end of the sliding module, and the supporting module is closely fitted to the bottom end of the beam.

[0004] The reinforcement structure provided by this technical solution can buffer the shaking between the beams and columns, thereby improving the supporting performance and increasing the stability of the connection between the beams and columns. At the same time, the reinforcement structure can support beams in three directions at the same time, which can meet the support requirements of most columns. However, in actual use, the diameter of the column is not uniform, and the clamping member cannot be effectively fixed to the column. At the same time, the device is equipped with vertical supports in multiple directions. The vertical supports here can only be set according to the preset angle and cannot be adjusted. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a reinforcement structure for beam and column nodes of ancient buildings, which solves the problems raised in the background art.

[0014] The beneficial effects of the present invention are:

[0015] 1. The ancient building beam and column node reinforcement structure is symmetrically arranged by setting two clamping members through bolts to connect the clamping members to the column. After the two halves of the threaded sleeve are connected, they are threadedly connected with the threaded half sleeve and moved upward, so that the wedge block can be squeezed upward by the extrusion rod, and then the extrusion rubber ring can be squeezed and deformed, so that it can be better fixed to the column, solving the problem of inconsistent column diameters and weak connections in the prior art.

[0016] 2. The ancient building beam and column node reinforcement structure limits the connecting plate to be parallel to the beam to be reinforced, inserts the sleeve into the outer surface of the connecting plate, and adjusts the threaded column, so that the crossbeam can be supported and reinforced by using the support bucket. By adjusting the angle of the clamping member when fixing and selecting arch beams of different lengths for cooperation, different beams in multiple directions can be reinforced and supported.

An extrusion rubber ring 9 is slidably connected to the interior of the bearing sleeve 8. A wedge block 10 is provided between the extrusion rubber ring 9 and the bearing sleeve 8. An extrusion rod 11 is fixedly mounted in the vertical direction of the wedge block 10. The extrusion rod 11 extends to the outside of the bearing sleeve 8. A threaded half sleeve 12 is fixedly mounted on the end of the bearing sleeve 8 away from the clamping member 1. The outer surface of the threaded half sleeve 12 is threadedly connected to an extrusion mechanism 13 which moves upward to squeeze the extrusion rod 11.

[0025] The vertical support member 7 includes an arch beam 14 fixedly connected to the sleeve 5, a threaded column 15 is threadedly connected to the middle part of the arch beam 14, and a support bucket 16 is rotatably connected above the threaded column 15.

[0026] A collar 17 is fixedly mounted on the bottom end of the support bucket 16, and a rotating plate 22 is rotatably connected to the inside of the collar 17. The rotating plate 22 is fixedly connected to the threaded column 15. This arrangement prevents the support bucket 16 from rotating when the crossbeam is located inside the support bucket 16, and the height adjustment is achieved only by the relative rotation of the collar 17 and the rotating plate 22.

[0027] The threaded column 15 extends to the bottom of the arch beam 14 , and a hexagonal square groove 18 is provided at the bottom end of the threaded column 15 , so that the threaded column 15 can be easily rotated.
