Problems solved by technology

The existing processing method for the used building wooden formwork is that there is no other better way to deal with these discarded building formwork than burning and landfilling. When burning, billowing smoke will be generated and a large amount of pungent toxic gas will be emitted. , resulting in more serious secondary pollution
The landfill method not only wastes land but also pollutes groundwater, and cannot fundamentally solve the problem of secondary pollution
[0003] This recycling method causes a lot of waste of wood resources, especially in today's world where tree resources are being exhausted day by day, this waste should be eliminated as soon as possible; in addition, the burning process will cause air pollution, which is not conducive to environmental protection

Abstract

The invention discloses a method for preparing building and packing templates with waste building templates as raw materials, and relates to the field of production processes of building wood templates. The method comprises waste template recovery, impurity removal, drying, core veneer processing, middle leather board processing, gluing, hot pressing, ash replenishing, sanding, wrapper gluing, cold pressing, hot pressing, edge sawing, polishing, final molding, inspection and delivery. The method effectively recovers, shapes and reuses waste building wood templates, so that the limited wood resource is saved, and the enterprise production cost is reduced to the greatest extent; and the method produces the building wood templates with high strength, high toughness, good levelness, light weight, no deformation, high stability, long service life and high waterproof cost performance, saves the resource for the society, is free of environmental pollution, and facilitates environmental protection.

Description

technical field [0001] The present invention relates to the production technology of the traditional building wooden formwork, and more specifically, relates to a method for preparing building and packaging formwork by using waste building formwork as raw material. Background technique [0002] Since 2011, the state has new regulations on the construction of high-rise buildings. Steel formwork should not be used, and wooden building formwork should be used. Therefore, tens of thousands of tons of wooden formwork are used in construction sites every day. Building wood formwork is an indispensable tool in the construction process, which directly affects the efficiency and quality of engineering construction. With the rapid development of the construction industry, the consumption of concrete formwork is increasing. According to incomplete statistics, the total consumption of formwork in 2012 was 5.8 million cubic meters, of which 3.2 million cubic meters were wood formwork, a...
