Description

Wood is moulded the little foaming construction formwork of skinning

Technical field

The utility model relates to building material field, and particularly a kind of wood is moulded the little foaming construction formwork of skinning.

Background technology

Construction formwork is the important tool of concrete structure engineering construction.At present, in the cast-in-place concrete structure engineering, form work engineering generally accounts for 20%～30% of concrete structure engineering cost, accounts for 30%～40% of engineering labour cost, accounts for about 50% of the duration.Mould plate technique directly influences quality, cost and the benefit of engineering construction, so it is an important content that promotes China's Building technology progress.

At the beginning of the seventies, construction formwork is based on wooden form.Wooden template applications the earliest owing to will consume a large amount of timber, and the easy splitting of dismounting template, the proportion of goods damageds are higher, the general number of turnover more should be sought substitute products at 4-6 time for China that the forest reserves do not enrich.The beginning of the eighties, construction formwork with steel form with the master.The steel template is the substitute of wooden template, and product is with standardization and formed series.Its advantage is to save a large amount of timber, and can be repeatedly used, and the turnover utilization rate can reach 40 times, but still has many shortcomings: 1. heavy, and lifting inconvenience in the construction, dismounting difficulty; 2. be subjected to weight limits, the single form area is little, and the splicing block number is more in the use, time-consuming, effort; 3. steel form and cement have certain affinity, and cement products surfaces such as easy column or crossbeam produce butcher cuts during the dismounting template, influence quality; 4. the easy corrosion of steel form.Since the nineties, China's architectural structure system has had very great development again, and highrise building, super highrise building and large public building are built in a large number, large-scale infrastructure construction, develop rapidly such as urban traffic and speedway, railway has proposed new requirement to template, scaffold construction technology.China constantly introduces external advanced mould bases system, has also developed multiple new type formwork and scaffold simultaneously.

Summary of the invention

The utility model provides a kind of wood to mould the little foaming construction formwork of skinning, and solve wooden template and wasted a large amount of timber, and the easy splitting of dismounting template, the proportion of goods damageds are than problems such as height.Lifting inconvenience in steel template heaviness, the construction, dismounting difficulty have been solved simultaneously, more, time-consuming, the effort of splicing block number in the use; Influence problems such as cement products quality and easy corrosion during the dismounting template.

It is to be main material with string (sawdust, wood chip, bamboo bits, straw, wheat tangerine, cavings, peanut shell, bagasse, cocoanut shell, inferior hemp etc.) that the utility model wood is moulded the little foaming construction formwork of skinning, makes it a kind of novel environmental-friendly construction material that is composited with resin (PVC, PP, PE) through preliminary treatment.Wood is moulded the little foaming construction formwork of skinning can save a large amount of timber, and all there is superiority aspects such as the convenient and swift and safety of construction; Wood is moulded and be need not maintenance and recyclable utilization, so can reduce production costs significantly, can also solve many key issues on the engineering.Its material source is extensive, is worth cheaply, and old material or compound all can.The wood-plastic products carefully and neatly done body synthetic products of behaving can be adjusted product technology and prescription at random according to instructions for use, thereby produces the material of different performance and shape, and its section bar utilization rate is near 100%.The wood of Wood-plastic material/mould base-material and the equal Environmental Safety of usual auxiliaries thereof, nontoxic, can not have side effects in its process of manufacture, so human body and environment are not all constituted any harm yet.Maintenance cost is extremely low, and life of product is several times as much as common natural timber.The scrap products of Wood-plastic material and reclaim the regeneration that waste product all can 100%, and can not influence the product functional performance.

The technical scheme that the utility model technical solution problem is taked is:

Wood is moulded the little foaming construction formwork of skinning, its structure comprises Wood-plastic microcellular foamed layer 1 and wood is moulded skinning cortex 2,3, wherein, the centre that wood is moulded the little foaming construction formwork of skinning is Wood-plastic microcellular foamed layer 1, this Wood-plastic microcellular foamed layer 1 inside and outside surface is respectively wood and moulds skinning cortex 2,3, and should Wood-plastic microcellular foamed layer 1 and wood mould skinning cortex 2,3 and be formed in one.

Advantage of the present utility model is:

(1) have good physicochemical characteristics, similar wood appearance is arranged, better than wood dimensional stability, can not produce crack, warpage, no timber knot, twill; The hardness height, long service life;

(2) have the secondary workability of similar wood, can saw, can dig, can bonding, available nail or screw fix maintenance easily;

(3) mothproof, mouse bite preventing, acid and alkali-resistance, corrosion-resistant, water imbibition is little;

(4) goods energy recycling, also degradable is beneficial to environmental protection.Practical.
