Abstract

The utility model discloses an incombustible light hollow wall board, which is composed of an external protection layer portion, an intermediate layer portion and a sandwich layer portion. The utility model is characterized in that the intermediate layer portion is a hollow structure with multiple arraying holes, and the filler on the edge of each hole is provided with inbuilt bamboo reinforcement with high intensity. Grids formed by the cross weave of nylon silk screens and bamboo chips are distributed in the fillers of the upper layer and the lower layer of the sandwich layer portion. Because the adopted materials are mainly the mixture of perlite and magnesian, the utility model has the advantages of high intensity, light structure, non-inflammability, light weight as wood, water resistance, insect resistance, acoustic insulation, heat preservation, cold resistance, thermal insulation, damp insulation, shock resistance, etc., and can be processed by planing, sawing, chiseling and cutting. The utility model can be used as boards for inner and outer walls, which greatly increases the utilization area.

Description

Incombustible light hollow wall board

The utility model belongs to the prefabricated panels that a kind of building is used, particularly a kind of incombustible light hollow sheet material, and the exterior wall or the inner partition wall that can be used as the rooms of buildings such as apartment, residential district dwelling house, office premises or prefabricated house with frame construction use.

Existing apartment and building, its exterior wall and the interior walls such as residential district apartment or office premises of building frame construction are not to be built into (at present many regional relevant departments hard and fast rule are to the dwelling house of frame construction, and interior exterior wall will be built into hollow brick) with hollow brick exactly with solid brick.Interior exterior wall to prefabricated house then adopts flammable veneer (timber is made) or other beaver boards.Adopt the hollow brick or the solid brick of vitrified bond to be built into interior exterior wall, have following shortcoming: the structure heaviness, as in thick 19cm brick cavity wall: every weight per square meter 300kg, every weight per square meter 400kg of thick 24cm.Floor space is big, causes actual usable floor area generally only to account for about 70% of gross floor area; The fragment of brick of vitrified bond is in sound insulation in addition, and thermal insulation, cold-resistant damp proof insulation, antidetonation aspect are also desirable not to the utmost.

To exterior wall in doing with veneer or other beaver boards, particularly make the interior exterior wall of prefabricated house, then exist problems (this class fire incident has discovery repeatly at present) such as easily burned, and the sheet material that timber is done exists also waterproof effect poor, problems such as distortion easily chap and wear out.

The purpose of this utility model is to overcome above-mentioned drawback, thereby designs a kind of light hollow inside and outside wall board material that adopts the incombustible material.Make it to become that a kind of intensity is big, light in structure, occupation of land are little, the wall board of health easy for installation, use applicable to the interior exterior wall wall board of making to have frame structure building, the inside and outside wall board material that also can make prefabricated house uses.

Technical solution adopted in the utility model is: it is made up of external protection, intermediate layer and interlayer three parts, its main feature is that the intermediate layer part is the vertically disposed hollow-core construction of multiple hole, is embedded with the bamboo reinforcement that can improve timber intensity in the peripheral filler of each hole; In the two-layer filler up and down of sandwich portion, be distributed with the grid of nylon yarn grid and bamboo chip interlacing.

Be further described below in conjunction with the concrete structure of accompanying drawing the utility model sheet material.

Fig. 1 is the generalized section of the utility model hollow plate;

Fig. 2 is the outline drawing of the utility model hollow plate;

Fig. 3 is the nylon mesh trrellis diagram in the interlayer;

Fig. 4 is the bamboo chip arrow diagram in the interlayer.

Wherein: the 1st, external protection, 2 interlayers, 3 nylon yarn grids, 4 bamboo chip grids, 5 intermediate layers, 6 bamboo reinforcements, 7 holes, 8 convex edge, 9 Baltimore grooves.

With reference to accompanying drawing; lower protective layer on the external protection 1(branch of this board, its bed thickness is 5-10mm) used material and intermediate layer 5 and fluctuate interlayer 2 used fillers mainly are to constitute (used a small amount of magnesium chloride solution is to make binding material to use) here by the perlite of 60%-90% and the mixture of magnesia and an amount of magnesium chloride.

Wherein, intermediate layer 5 and fluctuate interlayer 2 used fillers also can contain an amount of ripe glass fiber and sawmilling chaff additive.

With reference to accompanying drawing 1 and Fig. 2 also as can be known, a plurality of holes 7 are to be vertical block form to arrange.Having made at the edge of every block of sheet material is convex edge 8 on one side, Yi Bian be the bridge piece that Baltimore groove 9 is formed.During use every block of sheet material is drawn close, can be adopted angle steel and fastening bolt (or screw) to carry out the assembly unit connection up and down and get final product.

Use this novel hollow sheet material to have the following advantages:

(1) use nylon yarn grid and bamboo cane grid can strengthen timber intensity, structure is light and handy, avoided using metal material easily to get rusty and the problem of destroying monoblock sheet material.

(2) material in the external protection of sheet material and interlayer and intermediate layer is all with perlite and oxygen It is main changing magnesium, add the hollow pore space structure in intermediate layer, make that wall board is more light and handy, weight approaches or less than the weight of equal volume hardwood, and as available plane, saw as the timber, cut a hole, cut, twist the processing such as bolt, the inside and outside wall board material that both can be used in the building of frame structure uses, and can be satisfied with again the making needs of wallboard for prefabricated house material. Again because weight only is equivalent to 1/7th of equal volume brick wall, to the design-build of high-rise with reduce cost and will have significant meaning.

(3) particularly the perlite and the magnesium oxide material of external protection material employing incombustible constitute filler.Therefore whole sheet material embodies noninflammability.The advantage of water-fast in addition, mothproof simultaneously, sound insulation, insulation, cold-resistant, heat insulation, damp proof insulation, antidetonation.

(4) intensity of this board is good, during making the not enough brick wall thickness of its thickness half in addition littler, in the building area of existing two class rooms and three class rooms regulation, because of exterior wall floor space in it little, can have more usable floor area 7-12 square metre, thereby concerning resident family, have immeasurable meaning.
