Description

A kind of with discarded building template for the method for building, Packaging formwork prepared by raw material

Technical field

The present invention relates to the production technology of traditional construction timber shutterings, more particularly, particularly relate to a kind of with discarded building template for the method for building, Packaging formwork prepared by raw material.

Background technology

From 2011, there was new regulation in country to building high-rise building, must not use steel template, should adopt Wood construction formwork.Therefore, have every day the wooden template of thousands of ton to enter construction site to use.Construction timber shutterings is requisite instrument in work progress, and it directly affects efficiency and the quality of engineering construction.Along with the fast development of building trade, the consumption of concrete blinding is increasing, according to incomplete statistics, template total flow in 2012 is 580 ten thousand steres, wherein plank sheathing 320 ten thousand stere, the service life of plank sheathing is 5-10 time, the building template enormous amount that annual national building trade is discarded, cannot add up.In work progress, construction timber shutterings use amount is very large, needs clean out job site and recycle after being used to complete.The existing processing method to used construction timber shutterings is, these discarded building templates do not had other better treating methods except burning and landfill, can thick smoke be produced during burning, give out a large amount of pungent toxic gas, cause even more serious secondary pollution.Landfill method had not only wasted soil but also polluted underground water, fundamentally can not solve the problem of secondary pollution.

This recovery and treatment method causes very large waste to timber resources, and especially in today that current tellurian tree resources is day by day exhausted, this waste should be eliminated as early as possible; In addition, burning process can cause air pollution, is unfavorable for environmental protection.

Therefore, discarded building template harmless treatment, recycles forest resourceies, turns waste into wealth significant, meet the requirement of sustainable development.So the recycling of construction timber shutterings has become technical problem very urgent, urgently to be resolved hurrily.

Summary of the invention

The problem that 1, will solve

(3) template being processed into thickness is 10-13mm, the lath-shaped central layer of width 50-100mm, length 200-1500mm;

(4) be 1-3mm by making thickness after Wooden veneer or fiber cloth applying glue process, length is 2500mm, and width is the middle dermatotome of 1300mm, and described middle dermatotome is put into glue machine one side crosses glue;

(5) middle dermatotome one side in described step (4) being crossed glue is laid on iron plate or operating desk, and is laid on above the middle dermatotome after glue by the lath-shaped central layer of described step (3) gained;

(6) another one side being crossed dermatotome in glue has glue one cover not cross on glue face at the lath-shaped central layer completed, the whole plate of the shape that sandwiches;

(7) whole plate is sent into hot press hot pressing;

(8) whole plate is taken out from hot press, serves operating desk, carry out benefit ash manipulation, by imperfect on middle dermatotome or have cavity place fill ash;

(9) whole plate is sent into two-sided sanding in sander, make its plate face smooth, smooth;

(10) the whole plate after sanding is sent into double-faced uniform in gluing machine and cross glue, and mahogany musculus cutaneus material is laid on operating desk, the whole plate of described step (9) gained is laid on described mahogany musculus cutaneus material, then another mahogany musculus cutaneus material is laid on whole plate, make composite plate;

(11) composite plate is sent in cold press the 8-12 minute that colds pressing, required pressure is 12-16MPa;

(12) composite plate after colding pressing is sent into hot press hot pressing 50-70 second, required pressure is 12-16MPa;

(13) take out described step (12) gained composite plate, and send into sizing saw machine and saw limit according to the actual requirements, make its length and width reach requirement specification;

(14) by described step (13) saw limit after composite plate abrasive machine to its two polishing, sanding, then check, labeling, finally packing dispatch from the factory.

Further, what adopt in described step (4), step (6) and step (10) crosses the mixture that glue glue main component is urea-formaldehyde glue and flour 1:1 by volume.
