Embodiment 1

[0027] Take 100 parts of 65% water-based epoxy resin solution, 100 parts of triethylenetetramine, 200 parts of water, 800 parts of 32.5MPa strength grade cement, 1500 parts of corundum, and 50 parts of alkyl copper ammonium, mix and stir evenly according to the above components , that is, it can be made into the grouting material for repairing wooden structures of ancient buildings.

Embodiment 2

[0029] Take 100 parts of 65% aqueous epoxy resin solution, 150 parts of diethylenetriamine, 400 parts of water, 1500 parts of 42.5MPa strength grade cement, 1800 parts of river sand, 100 parts of ammonia-soluble copper arsenate, and 50 parts of fly ash According to the above components, mix and stir evenly to make the ancient building wood structure repair grouting material.

Embodiment 3

[0031] Take 100 parts of 65% water-based epoxy resin solution, 200 parts of m-phenylenediamine, 600 parts of water, 2000 parts of 52.5MPa strength grade cement, 3000 parts of river sand, 200 parts of copper chromium arsenic, 100 parts of fly ash, press The above components are mixed and stirred evenly, and the grouting material for restoring wooden structures of ancient buildings is made.

[0032] In the above implementation cases, the water-soluble wood preservatives can also be selected from fluorochrome phenol, fluorophenol mixture, boron phenol mixture, and acidic copper chromate.

Abstract

The invention discloses a grouting material for repairing a timber structure of an antique building. By using the grouting material, defects of a timber component of an antique building can be repaired by grouting consolidation in a situation that a roof support does not need to be pulled down in the repairing process of the timber structure, and simultaneously internal deinsectization and anti-corrosive treatment can be effectively carried out on a worm-eaten timber component. The grouting material for repairing comprises the following components in parts by weight: 100 parts of 65% aqueous epoxy resin solution, 100-200 parts of aqueous epoxy resin curing agent, 200-600 parts of water, 800-2000 parts of cement, 1500-3000 parts of sand, 50-200 parts of water soluble wood preservative and 0-100 parts of pulverized fuel ash.

Description

technical field [0001] The invention relates to the technical field of protection and repair of cultural relics and ancient buildings, in particular to a grouting material for repairing wooden structures of ancient buildings. technical background [0002] In China's long history and splendid culture, ancient architecture is an important part. According to survey statistics, there are more than 80,000 ancient buildings and historical monuments in my country. Among the 2,351 national key cultural relics protection units in six batches announced by the State Council, there are 1,083 ancient buildings, accounting for 46% of the total. [0003] Chinese ancient buildings use wood, bricks and tiles as the main building materials, and wood structures as the main structure. The wooden structure is composed of wooden columns, beams, purlins and rafters, etc., which are mainly interspersed and overlapped to form an elastic wooden frame. The flexible and convenient wooden frame struct...
