Problems solved by technology

However, because the bamboo curtain sizing not only has small adhesive force, but also has a large amount of sizing, and the production cost is high.
At the same time, there are some problems in the material selection and laminate stacking of ordinary bamboo-wood composite formwork, which leads to the lack of strength of bamboo-wood composite building formwork

Embodiment 1

[0024] A production process of bamboo-wood composite building formwork, comprising the following steps:

[0025] (1) Bamboo curtains, eucalyptus boards and poplar wood chips are baked in a drying room; bamboo curtains are woven into curtains from bamboo strips after removing bamboo green and strip yellow. The thickness of the bamboo curtain layer is 3.8mm, and the surface is woven; The thickness of poplar wood chips is 0.9mm; the temperature of the drying room is 80±3°C, the baking time is 55 hours, and the moisture content of bamboo curtains, eucalyptus wood boards and poplar wood veneers are all below 12% after baking;

[0026] (2) The baked eucalyptus board is sawed into rectangular wood chips, and the wood chips are closely fitted without overlapping, and the wood chips are assembled into a piece of eucalyptus wood board through glued seams; between the assembled rectangular wood chips and the rectangular wood chips no overlap and not left empty;

[0027] (3) Use the blen...

Abstract

The invention provides a production technology for a bamboo-wood composite building template. The production technology for the bamboo-wood composite building template comprises the following steps that step 1, bamboo curtains, eucalyptus planks and poplar wood pieces are dried in a drying room; step 2, the dried eucalyptus planks are sawn into rectangular wood pieces, the wood pieces are closely attached, no overlapping and gap exist, and the wood pieces are pieced together to form the eucalyptus planks through bonding threads; step 3, glue coating treatment is conducted on the pieced eucalyptus planks; step 4, the composite sequence is a poplar wood face layer, the eucalyptus plank, the bamboo curtain, the eucalyptus plank, the bamboo curtain, the eucalyptus plank and the poplar wood face layer, and the fiber directions of the eucalyptus planks are perpendicular to the fiber directions of the poplar wood face layers; step 5, the composite template is sent into a hydraulic machine to press; step 6, film coated paper impregnated with resin glue is laid on the pressed poplar wood face, and compression molding is conducted through a thermocompressor; step 7, after hot compression, edging and edge sealing of the periphery are conducted on the template. The production technology for the bamboo-wood composite building template adopts moso bamboo as a main material, the resources are rich, the price is cheap, and the production cost is low; the surface of the building template is flat and smooth, resin consumption is small, and the anti-bending and compressive strength are high.

Description

technical field [0001] The invention relates to the technical field of building construction materials manufacturing, in particular to a production process of bamboo-wood composite building formwork. Background technique [0002] Bamboo-wood composite building formwork is low in cost, and its bending and compressive strength meet the requirements of modern buildings. It is gradually replacing steel formwork and wood formwork and has become a rising star in the formwork industry. In order to make full use of the wood and make use of small pieces of wood, the traditional technology uses the splicing of small pieces of wood into a whole wood layer, but there will be overlapping parts between the wood chips after splicing, and it is necessary to manually use a knife to remove the overlapping parts of the wood. To ensure the smoothness of the entire building formwork, the surface of the building formwork made by manual grinding is not smooth enough, and bamboo strips will be left...
