Detailed Description
The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the embodiments.
Referring to the figures 1 and 2, the method for repairing the antique folk house wood structure comprises the following four parts
S1, three-proofing treatment: the method is used for improving the defects of easy worm damage, flammability and easy decay of wood structures, and performing fireproof, insect prevention and anticorrosion treatment on wood, namely firstly polishing the surface of a repaired house wood structure, wherein the number of brushing is not less than two, and after the first brushing drying operation, brushing is performed for the second time, and then the steps are repeated until the amount of the coated paint meets the required requirements, the brushing is sufficient, the brushing quality is ensured, and the crack part needs to be soaked by a preservative;
s2, removing and repairing or pier connecting: the method is used for repairing rotten parts of the wooden pillar, when the partial parts of the wooden pillar are rotten but the supporting strength of the whole structure can still meet the requirement of the service life of the structure, the wooden pillar is treated by adopting a method of repairing or pier connection. When the core of the column is intact and only the surface is decayed, removing the decayed part, after antiseptic treatment, using dry wood to repair the column according to the original size, using water-resistant adhesive to adhere the column firmly, and adding steel plate stirrups to perform 1-3 times of hooping; when the column foot is rotten seriously but does not exceed 1/4 of the height of the column from the bottom surface of the column upwards, the column foot is connected with the column foot in a pier mode, and a new column foot is added for treatment, and it needs to be noted that a support column needs to be added before the pier connection process is constructed, the load of the original column is relieved, and the construction can be carried out only after the safety is ensured;
s3, embedding and repairing: the method is used for repairing the drying shrinkage cracks on the wood columns and respectively carrying out corresponding treatment according to different depths of the drying shrinkage cracks;
when the width of the drying shrinkage crack is not more than 3mm, the wood column is tightly plastered by putty in the process of oil decoration or white breaking.
When the width of the drying shrinkage crack is 3-30mm, the wood strip is embedded and firmly bonded by using a water-resistant adhesive.
When the width of the dry shrinkage crack is larger than 30mm, firstly, the width of the dry shrinkage crack is embedded and fixed by a water-resistant adhesive by using a wood strip, and then an iron hoop is added in the cracking section of the dry shrinkage crack to fix the wood strip.
When the width of the dry shrinkage crack is larger than 500mm, the steel plate stirrup is embedded into the dry shrinkage crack, the outer skin of the steel plate stirrup is flush with the outer skin of the wood column and hooped and inserted into the batten or the wood block of the dry shrinkage crack, and the batten or the wood block is firmly adhered by a water-resistant adhesive.
And after the construction is finished, the structural column is subjected to polishing process construction, and then the surface is subjected to three-proofing treatment.
And S4, finally, the wood purlin 1 (truss) is small in size and well stored, and purlins 2 are added at positions with large roof loads, so that the purposes of reducing the loads of the original building structure and ensuring the overall safety and reliability of the building are achieved.
Through the key development of the invention, the antique folk house wood structure repairing technology ensures the building safety, improves the wood utilization rate, reduces the resource waste and protects the ecological environment; and the technology has simple and standardized implementation steps and high reliability, and is favorable for wide popularization and application of archaizing folk house project construction.
As above, while the invention has been shown and described with reference to certain preferred embodiments, it is not to be construed as limited thereto.
