In-situ reinforcement planting perfusion reinforcement method of local rotten ancient wooden beams

Abstract

The invention provides an in-situ reinforcement planting perfusion reinforcement method of local rotten ancient wooden beams. The reinforcement method comprises the following steps of positioning rotten positions of the wooden beams; arranging support rods and base plates on both sides of the rotten positions of the wooden beams; removing rotten woods at the rotten positions of the wooden beams toform holes; arranging a plurality of reinforcement planting holes parallel to longitudinal axis directions of the wooden beams on both sides of the holes in a drilling mode; injecting appropriate amount of structural adhesives into each reinforcement planting reinforcement hole, and inserting reinforcing reinforcements to make the reinforcing reinforcements firmly bond with the wood beams; adopting templates to wrap the wood beams at the holes, and pouring polymer grouting materials until the holes are filled; and removing the templates, support rods and base plates after the grouting materials to be poured are completely solidified. The reinforcement method reinforces and repairs the local severely rotten wood beams without dropping a frame, and restores the bending bearing capacity of the wood beams without changing appearances of the wood beams.

Description

technical field [0001] The invention relates to the technical field of repairing wooden structures of ancient buildings, in particular to a method for in-situ rebar perfusion reinforcement of locally decayed wooden beams of ancient buildings. Background technique [0002] Ancient architecture is a combination of science, technology, culture, knowledge and art, and is also an important historical carrier, carrying rich humanistic connotations. The ancient buildings in our country are dominated by wooden structures, and brilliant achievements have been made in architectural planning, structural construction, culture and art. Many ancient wooden structures have been standing upright to this day, demonstrating the excellent characteristics of wooden structures. [0003] During the long-term service of ancient wooden structures, various damages will inevitably occur due to the action of various loads and the erosion of the natural environment. When the wooden beams of ancient b...
