Production process for alternately-laminated building block

Abstract

The invention discloses a production process for an alternately-laminated building block. The production process comprises the steps that firstly, douglas-fir, southern pine, Chinese fast-growing poplar and the like are dried and degreased till the water content of the douglas-fir, the southern pine and the Chinese fast-growing poplar reaches 4%, then moisture regain is conducted till the water content is 12%, the douglas-fir, the southern pine and the Chinese fast-growing poplar are dried at the high temperature of 180 DEG C through a vacuum high-temperature cellar, and then the douglas-fir, the southern pine and the Chinese fast-growing poplar are put into a balancing room and placed for 20 days; secondly, shaving, cutting, material sorting, gear milling and finger joint are conducted, and a piece of laminated timber is obtained; thirdly, the four faces of the laminated timber are polished and glued, 17 kg of longitudinal jointed boards are pressurized with an A-shaped makeup into longitudinal boards, and parts of the longitudinal boards are selected and machined into transverse boards; and finally the longitudinal boards and the transverse boards are correspondingly coated with waterproof glue for the outdoor, longitudinally and transversely stacked into 3-9 layers and then pressed with a 400-ton pressing machine, then curing and moisture regain are conducted for 48 hours, and then the alternately-laminated building block material is obtained. The alternately-laminated building block material produced through the method is low-carbon, environmentally-friendly and high in construction efficiency; and most importantly, the alternately-laminated building block material has extremely high strength, fire resistance and shock resistance and is the only environmental-friendly low-carbon building material capable of replacing reinforced concrete.

Description

technical field [0001] The invention relates to the field of wooden materials for construction and furniture, in particular to a production process of cross-layered building blocks. Background technique [0002] At present, most of the wood used in our house construction and furniture production, especially in the production of pure wooden houses, is made of wood squares sawn from a single trunk. The square is also easily deformed, cracked or broken. Synthetic wooden squares can solve the above problems, but because the existing synthetic method is formed by superimposing and bonding wooden squares layer by layer, it is easy to produce phenomena such as cracking, exposed glue, deformation, etc., and has not been promoted and applied. Contents of the invention [0003] The invention overcomes the disadvantages of the above-mentioned wood cube manufacturing method, and provides a cross-laminated wood production process. [0004] The present invention is achieved through th...
