Problems solved by technology

[0002] The principle in the restoration and protection of large trees in ancient buildings is not to destroy the main body of the large wood, as well as the reversibility and recognizability of the construction, to minimize the interference with the main body of the large wood, and to protect the original appearance and raw materials of the large wood as much as possible; Aging, wind and rain erosion, and building load-bearing can easily lead to cracks in the big wood. If it is not repaired in time, the big wood will lose its load-bearing function
Timely repair requires an economical, applicable and reversible repair material and process to better protect the large wooden components of ancient buildings, prolong the service life of the large wood, and avoid greater damage caused by cracks and irreparable losses

Embodiment 1

[0011] A kind of wood crack repairing material for the repair of large logs in ancient buildings, which is mixed with wood chips, 40 mesh water sand, gypsum powder, bone glue, clear water, and paint in a certain proportion, wherein the mass percentage of each component is wood chips 30%, 40 mesh water Mingsha 21%, gypsum powder 12%, bone glue 15%, clear water 10%, paint 12%.

[0012] The mixing sequence of each component includes the following steps: 1. Mix and stir the sawdust and Mingsha evenly; 2. Add water to the bone glue and boil until boiling, and stir it into a paste; 3. Mix the paste-like bone glue with the sawdust and Mingsha Mix and stir well; 4. Add the paint and continue stirring until uniform.

[0013] Based on the above-mentioned repairing materials, the wood crack repairing process for the repair of large wooden buildings in ancient buildings, ramming and rolling evenly mixed repairing materials into the wood gaps, repeatedly ramming until uniform and compact, ...

Abstract

The invention discloses a wood crack repair material for repairing ancient building big wood and a repair technology thereof. The wood crack repair material is prepared through blending of, in percentage by mass, 30-40% of wood flour, 15-22% of 40-mesh free sand, 8-12% of gypsum powder, 8-15% of bone glue, 5-10% of clean water and 6-12% of oil paint; and the blending sequence of the components isthat 1, wood flour and free sand are blended and stirred to be uniform; 2, water is added into bone glue and heated to be boiled, and then mixture is stirred to be pasty; 3, the pasty bone glue and the mixture of bone glue and free sand are mixed and stirred to be uniform; and 4, the oil paint is added, and the mixture is stirred continuously to be uniform. The prepared repair material is low in cost and convenient to manufacture, can perfectly adapt to the environment, thus the erosion and damage of the repair material to the ancient building big wood body are reduced to the largest extent, and the repair material has the reversibility and identifiability, can protect the original appearance and the authenticity of the big wood for the largest possible, and better achieves crack repair ofancient building big wood components.
