Description

The construction wall plate that string and formaldehydeless wood-based plate are compound

The purpose of this invention is to provide various plants fiber and the light-weight building antidetonation ash wall body plate that does not contain the compound composition of lightweight bamboo wood artificial board of formaldehyde, phenol type substances.

Building trade is to adopt the frame body and the floor panel of steel and concrete structure casting basically in building at present.But the partition wall of body of wall still is piled into body of wall with clay, shale brick, cement mortar, and he has increased the supporting power of frame body to this body of wall to one cubic metre of 1.4-1.6 ton than great, occupies cultivated land in a large number and consumes energy when firing clay, shale brick.To this: " General Office of the State Council in 1999 has just issued about advancing modernization of the housing industry to improve some suggestions of housing quality ", hollow concrete block has just appearred subsequently, substitution material such as clinker brick, air parcel brick, but still use clay, shale brick in small and medium-sized cities and overwhelming majority building site, earthquake-stricken area.Promptly a large amount of in rebuilding behind the Wenchuan earthquake with clay, shale brick.Be air parcel brick, clinker brick, can't enter small-scale production with regard to its reason, hollow concrete block is not suitable for the disaster relief again to be needed and fast requirement of time.

Industrialized house has appearred recent years, this technology and form from Europe and Japan introduce, introducing the back does not have much innovations on design and building theory.This dwelling house is to be support with steel pipe as skeleton, is aided with gypsum and makes panel, and the glass heat-insulating composite cotton fabric is the composite wall body material that sandwich of layers is made.Though this body of wall is lighter than clay, shale brick, cost exceeds 20% than clay, shale brick, hollow concrete block valency, and uses steel pipe as the keel frame in a large number, and this tube material, is led noise and easy-to-rust at conductive and heat-conductive.And that gypsum is made the panel impact resistance is poor, and easily fragmentation is hurted sb.'s feelings.Therefore a kind of not only formaldehydeless, phenol type substances, but also light weight, inexpensive are provided, and easily the composite wall board of the Rapid Combination lightweight of installing, environmental protection, energy-conservation, consumption reduction is exactly inventor's a purpose.

The present invention is achieved in that

One, utilize strings such as the discarded in a large number straw in Chinese vast rural area, forest zone, tangerine bar, leaf, cogongrass to make raw material, provide high temperature, low pressure facility and technology by the owner, send in the specific press after string being chopped into the particle of 50-100 millimeters long with machinery, utilize the starch of string in health, fat, carbohydrate, protein through the low pressure of 110--120 ° of high temperature at press, change into the mucilaginous gum agent under the hot conditions and come bonding string body, make it be configured as stick type, cavernous lightweight Gu Ti Block.Its density is between 0.04 to 0.1, press pressure is controlled between the 0.4-1 MPa in the operation, never can exceed a MPa, temperature is strict controlled between 110--120 °, so both killed the disease hyphal body, can make string self moisture content become gas again and go out, form the cellular solid profiles, the sandwich of layers that is made for the light building wall plate is used.With this method the equipment and technology personnel are dispersed in rural area, mountain area, by the owner furnished equipment technology, it is stand-by that peasant's processing becomes product to store.The fund factory building that so not only reduces enterprise is thrown in and also have been increased peasant income and employment, has reduced burning tangerine bar etc. and has brought environment pollution.And economic benefit and properties of product all are higher than gypsum plank.

Two, the formaldehydeless lightweight bamboo wood artificial board of producing with (application number 2010162078.5) technology of inventor's patent applied for, this material unit weight is between 0.4-0.6.Be combined into the formaldehydeless class environmental-friendly walling of lightweight plate as combined wall panel and string solid bodies.The common ash wall body plate of this type is without adhesive, and special ash wall body plate can be carried out compound assembling with a small amount of protein binder, and plate thickness is between the 5-10 millimeter, and its anti-impact force is better than the phenolic aldehyde bamboo offset plate and the lightweight steel pipe keel frame gypsum plank of stack pile.Simultaneously can be in body of wall pre-buried power circuit, small-bore water pipe, various electrical equipment leads, the two sides outer panels can be coated with pastes multiple decorative pattern and fireproof paint, it is antistatic to particularly point out this product, can the waterproof etch.

Three, body of wall gravity supports and adopts formaldehydeless thick type bamboo wood artificial board to amass into balk, thickness is between the 30-50 millimeter, width between the 110-180 millimeter (unit weight 0.4-0.6/ cubic meter) as the support frame material, amassing into balk 4--6 spare by square face 12-20 square metre calculating of each body of wall with wood-based plate gets final product, its support force intensity surpasses steel joist frame 50%, cost low 30%, and it is nonhygroscopic, conduction, and heat insulation effect is stronger than glass heat-insulating composite cotton fabric, and confirmed on probation with 200 millimeters thick bodies of wall in actual the use with 4 years after tested: interior temperature still can remain on about 10 ℃ under-20 ° of severe cold.Soundproof effect is good than clay, shale brick body of wall, and 75 decibels noise is unable in 150 millimeters thick bodies of wall penetrates immersion.

Four, body of wall is installed: this composite wall board is installed and is adopted formaldehydeless class lightweight synthetic plate balk, with 30-50 millimeter thickness, rise with splashing again gong bolt or penetrate fourth balk is fastened on the steel reinforced concrete cement room Vierendeel girder of 110-180 millimeter width balk, generally need not use adhesive when fastening, if any special requirement, can be coated with in the connection place and can connect firmly with a small amount of protein binder or amylum adhesive that (Ancient Chinese substitutes the bonding stone Gong Qiao of these two kinds of adhesives, large-scale city wall, go through hundreds of year still effective), this light wall material, each cubic meter can be done 8 square metres of 120 millimeters thick bodies of wall, 6.5 square metres of the bodies of wall of 150 millimeters thick, 5 square metres of the bodies of wall of 200 millimeters thick.Therefore every weight per square meter of whole body of wall only has between 5 kilograms to 10 kilograms, and most bodies of wall are between the 6-8 kilogram, even meet and reach earthquake more than 8.5 grades by force, steel reinforced concrete building body paralysis collapses and hurts sb.'s feelings can not produce the body of wall pulverizing, be exactly that the materials for wall total head is on human body, its weight only has the 6-8 kilogram for every square metre, has not had hard tapered object and has stabbed human body, more can not cause mortal injury (steel reinforced concrete frame beam is directly being pressed except the people) to human body.

Five, this composite wall board, except that in light weight, poisonous and harmful substances such as intensity is high, shock resistance, formaldehydeless, phenol discharge, also have and lack land occupation than masonry walls, increased living floor space, reach the saving soil, energy-saving and cost-reducing, cost is low, the purpose that speed of application is fast is specially adapted to highrise building and post-disaster reconstruction anti-seismic heat-preservation room, mountain area.Should be understood that before the present invention, plant fiber molding is become artificial board, but they carry out under HTHP after being added with the binder of formaldehyde so that technology to be arranged.The panel density of product is big, thickness and rigidity deficiency, and two-sided metope be water silt ash be coated with thick form make wall panel and my ash wall body plate composition, the production technology actual effect is different.

After below the composite wall board of string and clay, the thorough body of wall of shale brick and gypsum plank, steel pipe keel frame glass heat-insulating composite cotton fabric ash wall body plate cost being in contrast to.

Rebuilding the room with the Wenchuan earthquake disaster area is example:

140 millimeters thick clays, each construction cost per square meter 115-125 unit of shale brick wall.

Gypsum plank steel pipe keel frame adds glass heat-insulating composite cotton fabric body of wall, a construction cost per square meter 136-140 unit.

One square metre of 90-105 unit of string composite wall board saves 10-20%.

Six, aggregate erection speed is fast, and bury brick heap is thorough to need 1 month quality stationary phase after good at least, because of humidity needed to move in 3 months-6 months.Artificial 4 hours of brick one cubic metre of need, the mortar of cementing outward needs one hour, and 12 square metre of one face wall needs two days.And gypsum, glass heat-insulating composite cotton fabric add steel pipe keel frame and build one group of wall and need 5-7 days.And only needing just can finish in one day with the installation of string ash wall body plate, the experienced operator does only half a day (4 hours), can finish the installation of 12 square metres of bodies of wall.

Seven, installation procedure: carry out the formaldehydeless bamboo wood of thick type balk in advance by square physical dimension of construction wall, general thickness 30-50 millimeter, width 110-180 millimeter can bear 200 kilograms of impact forces of every square centimeter of unit completely fully.The splash Luo Shuanhuo that rises of use penetrates fourth, and balk is connected with house steel reinforced concrete framework, and general every 12-20 quadrature body of wall get final product with balk 4--6 root, then formaldehydeless bamboo wood lightweight panels and the compound installation afterwards of string body of wall piecemeal can be become a width of cloth integral wall.Thickness of wall body, the area size increases and decreases according to user's request fully.

Eight, production process: string is broken to be cut → cellular Xian Wei Block body heat low pressure compacting → formaldehydeless bamboo wood artificial board production → Xian Wei Ban Block body and formaldehydeless bamboo wooden man make panel compound → every index → examination is installed → is detected at the scene.
