Abstract

The invention discloses a manufacturing method of prefabricated bending integrated materials. The manufacturing method of the prefabricated bending integrated materials comprises the following steps that a plurality of wood plates with the preset thickness are provided; a part of wood plates in the plurality of wood plates are in longitudinal finger joint in pairs; the elastic stage maximum interference degree of a plurality of layer plates is measured, and in addition, the bendable minimum curvature radius of each layer plate is calculated; the plurality of layer plates are used for being processed into the prefabricated bending integrated materials with different curvature radii; the prefabricated bending integrated materials are placed until the prefabricated bending integrated materials cannot deform, then, the actual curvature radii of the prefabricated bending integrated materials are measured, and next, the relationship curve and the function relationship of the actual curvature radius and the processing curvature radius are established; according to the actually required curvature radius, the processing curvature radius is obtained through the calculation via the function relationship, and the prefabricated bending integrated materials with the corresponding processing curvature radius can be obtained through processing. The manufacturing method of the prefabricated bending integrated materials is simple and feasible, and the implementation is convenient.

Description

technical field [0001] The invention relates to a method for making prefabricated curved laminated materials. Background technique [0002] With the development of the wood structure construction industry in China, heavy wood structure buildings have entered the lives of Chinese people, and a large number of curved glulam buildings have appeared, including large public buildings and wooden bridges. A large number of curved glulams are used in such buildings, and There are certain difficulties in the design and production of curved glulam. After the curved glulam is processed, it often deforms, springs back, etc., making the engineering site unusable. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a method for making prefabricated curved glulam. [0004] The method for making prefabricated curved glulam according to an emb...
