Embodiment Construction

[0020] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, now refer to the attached figure 1 Specific embodiments of the present invention will be described. A cross-laminated board prepared based on tenon rotary friction welding technology, characterized in that the cut longitudinal laminate 1 and the transverse laminate 2 are assembled at a certain angle, and then the surrounding is fixed with a template, and the Drill holes on the surface of the board at a certain interval and at a certain angle, drill the wooden tenons 3 fixed on the drill bit into the holes, and remove the template after all the holes are drilled into the wooden tenons 3 and the redundant wooden tenons 3 are cut off. Include the following steps:

[0021] 1) Sawn timber cutting: the size of the pre-designed cross-laminated board is 2.4m×4.8m, the thickness of the longitudinal laminate 1 and the transverse laminate 2 are both 20mm, the number ...

Abstract

A cross-laminated plate manufactured on the basis of a dowel rotary friction welding technology is characterized in that longitudinal laminated plates (1) which are cut and transverse laminated plates(2) which are cut are assembled according to a certain angle, then the peripheries of the plates are fixed by a formwork, punching operation is conducted on the plate surfaces at intervals accordingto a certain angle, dowels (3) which are fixed to a drill bit are put into holes in a drilling mode, and the formwork is disassembled after the dowels (3) are put into all the holes in the drilling mode and the redundant dowels (3) are cut away. The dowel rotary friction welding technology is adopted to optimize a conventional production technology of cross-laminated timber, and the improved technology is free of usage of adhesives and nails and is greener and more environmentally friendly. Due to the fact that plate components are designed in advance, secondary cutting is not required after the formwork is disassembled, and the utilization rate of raw materials is improved.

Description

technical field [0001] The invention relates to a cross-laminated board prepared based on a tenon rotary friction welding technology, which is applied to a roof panel of a low-rise building or a wall panel of a low-rise or multi-storey building, and belongs to the field of construction engineering. Background technique [0002] Orthogonal glulam, also known as cross-laminated lumber, is a new type of prefabricated engineered wood product with great potential. It is composed of at least 3 layers of solid wood sawn timber or structural composite panels at a certain angle, glued with structural adhesives or nailed. made. However, the production of both adhesives and nails has an impact on the environment. [0003] Tenon rotary friction welding technology is a processing method and connection form of wooden components with great potential. The tenon is inserted into the reserved hole under the condition of high-speed rotation. Under the joint action of high-speed rotation, due ...
