Abstract
The present invention relates to build a kind of prefabricated units of non or vertical partition wall and so on, and it is with the top layer of glass fiber reinforced cement as wallboard, with the combined wall board prefabricated units of leca sand-free coarse porous concrete as sandwich.Its functional performance is good, be convenient to construction, nail is wrapped up in power by force and comparatively economical, and cost is low.
Description
The present invention relates to build a kind of prefabricated units of non or vertical partition wall and so on.
What non in the construction work and so on use at present was more is that cinder concrete is taken out hole precast plate or leca sand-free coarse porous concrete piece, and they are respectively by a kind of mortar moulding by casting that mixes.Processings of must plastering of all lower, easy to break, the rapid wear of these two kinds of component strengths, and appearance is coarse, construction rear surface, operation take a lot of work, time-consuming, expense is expected, less economical.A kind of partition board appears in recent years, it adopts the glass fiber reinforced cement manufacturing, have the intensity height, surface quality is good, characteristics such as construction saving of work and time, but its weak point is: 1, usability is still not good enough: it is poor to wrap up in power as nail, the fire resistance period of fireproof performance such as hollowcore slab be about 0.5 hour not ideal enough; 2, product cost is higher.
The objective of the invention is to avoid weak point of the prior art, and provide a kind of usability good, again Jing Ji prefabricated panel member.
Can take following technical scheme to realize purpose, do the top layer of wallboard, make the combined wall board prefabricated units as sandwich with the leca sand-free coarse porous concrete with glass fiber reinforced cement.
In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.
Accompanying drawing is the combined wall board schematic cross-sectional view.
The top layer of combined wall board (1) is a housing parts, adopts glass fiber reinforced cement to make.Cement can be selected aluminium sulfate high-early (strength) cement or Portland cement for use, and they should meet ZBQ11005-87 standard, JC101-81 standard respectively.Select aluminium sulfate high-early (strength) cement 25～35% by weight for use No. 425, medium sand 25～35% is with after perlite 8～15% mixes, surplus part is mixing water again, and the top layer that is distributed in wherein when glass fiber weaved into the cast of net sheet to be constituted has functional performance and comprehensive economic index preferably.Mix the expanded perlite material that meets JC209-77 part cloth standard, unit weight 80～150Kg/m3 on the top layer and can make goods improve respiratory, wallboard dewfall phenomenon in use can not occur, and goods had can saw, dig, performance such as nail.The consumption of glass fiber can get final product by the adding of 0.2～1% weight.
The sandwich of combined wall board (2) adopts the leca sand-free coarse porous concrete to make.Leca should meet the JB51-78 national standard, selects for use capacity less than 400Kg/m
3Ultralight be advisable for 400 grades.Mix with No. 425 aluminium sulfate high-early (strength) cements 29～30%, flyash 2～4% after adopting leca 50～60% humidifyings by weight, the surplus part core material that mixing water constituted again is comparatively desirable.Add flyash and can improve cement paste and wrap up in the amount that is attached to the haydite top layer in the slurry of sand-free coarse porous concrete, improve workability, increase the surface area of slurry, corresponding saving cement also reduces cost.
Do the top layer with glass fiber reinforced cement, the prefabricated units of making sandwich with the leca sand-free coarse porous concrete can be made into takes out orifice plate and two kinds of goods of real central layer.Taking out orifice plate is advisable with hole ratio 28～35%.
Smooth bright and clean for guaranteeing board product, bed die selects for use glass epoxy to be bonded in concrete, constitutes on the base.Must use by coating release agent after cleaning wiping mould therefor, during making, skin-material and core material will separately stir, use respectively, must not mix and mix usefulness; All must earlier driedly stir well before two kinds of materials stir even after, add the water stirring again.To leca is elder generation self humidifying, and then with do to mix the cement that stirs, flyash mixes, adds water and stirs, make the leca surface evenly roll sticking cement paste, stick cement paste and present " metallic luster ", dry hide and stream slurry phenomenon must not occur for good with range estimation haydite surface, take out Kong Shiying carried out after the cement initial set in 10 minutes, as under the natural curing condition, if environment temperature is more than 20 ℃ the time, cast, quiet stopping can be taken out the hole after 20～30 minutes; In the time of 10～20 ℃, take out the hole after 40～50 minutes, in the time of 5～10 ℃, take out the hole after 1～1.5 hour.The hole time is taken out in assurance can be made flat appearance, avoids occurring collapse phenomenon.So preparation is comparatively suitable in the environment more than 5 ℃, and follow general cement products conventional curing requirements, guarantee that quiet stopping can use after 28 days.
Take out the hole composite wallboard product by what technique scheme was made 2540 * 595 * 60mm, its key technical indexes is as follows:
Plate deadweight 65～70Kg/ piece 42～46Kg/m
2
Unit weight 700～750Kg/m
3
Compressive strength＞5MPa
Anti-the fractureing of bending resistance load＞100Kg(split maximum load)
Impact resistance 10Kg drop 1m impacts＞100 ends and crackle occurs
Water absorption rate 20～28%
Sound transmission loss 33db
Fire resistance period 1h
Combined wall board has following advantage:
1, serviceability is good:
It not only had the performances such as the characteristic, intensity height of cement products, heat insulation, sound insulation good, but also have the light characteristics of body; This system Lu has follows closely, can saw, can dig, can bonding construction extremely convenient, this is that general cement products is incomparable, especially to wrap up in power be people's popular welcomes to its nail; These goods are better than taking out glass fiber reinforced cement (the being called for short GRC) goods of porosity 63% on fire protecting performance, the real central layer fire resistance period of these goods is 1.5 hours, taking out the orifice plate fire resistance period is 1 hour, and GRC cored slab goods fire resistance period is 0.5 hour. 2, good economy performance: its surface smoothness height, in Application in Building, need not plaster, reduce again easy construction of construction costs; It is than GRC goods cost.
Claims (2)
1, a kind of wallboard, it adopts the glass fiber reinforced cement manufacturing, and it is characterized in that: it is with the top layer of glass fiber reinforced cement as wallboard, with the prefabricated units of leca sand-free coarse porous concrete as sandwich.
2, wallboard as claimed in claim 1, it is characterized in that: the glass fiber reinforced cement on top layer is by weight by aluminium sulfate high-early (strength) cement 25～35%, medium sand 25～35% is smeared the Heshui surplus again with after perlite 8～15% mixes, and glass fiber is weaved into the net sheet is distributed in wherein and constitutes; The leca sand-free coarse porous concrete of sandwich is by weight by leca 50～60% humidifyings, with after aluminium sulfate high-early (strength) cement 20～30%, flyash 2～4% mix again the mixing water surplus constitute.
