Description

A kind of production method of decorative buiding block of concrete

At present, the decorative buiding block of concrete that architectural engineering is used is produced by make-up machine and auxiliary equipment, and equipment investment is big, does not wait to units up to a million from hundreds of thousands unit.The coloring process of decorative buiding block of concrete is general to adopt four kinds, i.e. spraying, integral colouring, surface are coated with rinses and firing process.Problems such as these several technologies can cause the building block color not bright-coloured owing to exist problem such as the weak or pigment dispersion of pigment adhesive force, and decorative effect is undesirable, and weatherability is relatively poor.And the technology of production own is complicated like this, and raw materials consumption is big, and labour cost is higher, causes cost to increase.It is reported that such decoration concrete building block market price is RMB 700-1100 unit/m at present ³, and ordinary concrete building-block, fly ash building block market price are 120 yuan/m of RMB ³About, lack the market competitiveness.

And this class is decorated concrete building block shortage insulation effect.The American has invented foamed plastics has been inserted in the building block hole, makes building block have insulation effect, but foamed plastics and building block itself do not form an integral body, and there is not the binding reinforcing bar in inside, so the intensity of building block can not get strengthening.

The purpose of this invention is to provide a kind of small investment, cost is low, easy and simple to handle, and bright-colored, have multicolour pattern, good weatherability, colour-fast, intensity is higher and have the production method of the decoration concrete building block of insulation effect.

To achieve these goals, the present invention adopts the laminated pouring method, earlier at mould of plastics bottom pouring one deck band pigment decorative layer, pours into a mould one deck ordinary concrete more in the above.In mould, put into the foamed plastics that couples together with reinforcing bar then.Pour into a mould ordinary concrete for the second time again in the space of mould, water fill with after, the floating maintenance a few days demoulding of jolt ramming both finished product, at room temperature the maintenance a few days just can dispatch from the factory again.

This kind mode of production can also change quartz sand into color sand in the prescription of decorative layer, behind the shaping and demoulding decorative cover is polished with the sander polishing and with polishing machine.

The mold bottom of this kind mode of production can be the plane, also can be with various patterns.Can produce the decorative block of different colours according to the different colours of pigment.

This kind mode can also be set up the grid of a fixed mould on shake table, set up an energy is put into foamed plastics mould by pre-designed position positioner again.

A small amount of industrial residue (comprising spoil, kiln ash, flyash, slag, lime etc.) can be added in the ordinary concrete in this kind mode on request but its component will lack, the cementing strength of cement can not be influenced.

Can be with this mode also to produce the building block of solid decoration concrete.Foamed plastics need only be removed and both can.

Adopt the method to produce and decorate the concrete building block, can reduce equipment investment, all devices adds mould only needs 1-2 just can produce in batches for ten thousand yuan.Because the way of laminated pouring has been adopted in this invention, the pigment of decorative layer is concentrated, owing in decorative layer, add chemical industry auxiliary material brightener, make the bright-colored of building block again, be rich in glossiness, weatherability strengthens, and is difficult for the armpit look.Because only add pigment in decorative layer and reduced the complexity of technology, product cost reduces, and estimates that this produce market price is 400 yuan/m ³About.

The decoration concrete building block that this kind method is produced makes product alleviate weight and has reached heat insulation effect again owing to manage into foamed plastics during moulding by casting.And between foamed plastics, adopting reinforcing bar to link, reinforcing bar is improved the intensity of building block own at the inner tension force that produces of building block after the moulding.

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.

Fig. 1 is the cutaway view of cast decorative layer after jolt ramming.

Fig. 2 is the cutaway view after the jolt ramming of cast second layer ordinary concrete.

Fig. 3 is for adding the cutaway view behind the foamed plastics that connecting reinforcement is arranged.

Fig. 4 is the cutaway view of last cast ordinary concrete jolt ramming after floating.

The decorative layer 1 of cast earlier shown in Figure 1.Die size should be by the requirement design of country to the concrete building block.The raw material of decorative layer should be mixed in proportion and stirs before the cast.The composition of raw materials of decorative layer is a white cement: quartz sand: brightener: pigment=1: 1～1.5: 0.02～0.03: 0.01～0.03 is resize ratio as required also.Add water again and become pasty state in right amount, injection molding then stirs.Cast thickness is 2-5mm, is placed on jolt ramming discharge bubble on the shake table then.

As shown in Figure 2, need after the decorative layer jolt ramming to place a period of time, be generally about 1 hour.The low time of temperature is long, and the high time of temperature is short.Observe and touch decorative layer hardness, be difficult for squishing the back for suiting with finger with sensation with hand.But should not place long-time.Pour into a mould second layer ordinary concrete 2 this moment in the above.The match ratio of ordinary concrete by country to the concrete building block the requirement of strength preparation that should reach and stirring.The shake table jolt ramming of cast back.Its thickness should be consistent with the sidewall thickness of common building-block.

Shown in Figure 3, will with the polystyrene foam plastics 3 and 4 of the basic the same size of the hole of common hollow concrete building block in advance with reinforcing bars 5 and 6 bindings, be placed into then in the mould, place on the concrete surface after the jolt ramming.

Shown in Figure 4, with ocular estimate test, the distance between the foam-plastic blocks and they and mould be the distance of wall all around.Adjust this distance and make this distance and the wall thickness basically identical of ordinary concrete hollow block.Live foamed plastics with a hand then, the another manual tool is poured into a mould the ordinary concrete that stirs in mould.Space 7 remaining in the mould is filled up fully, and used shake table jolt ramming, the surface is floating.The sale of just can dispatching from the factory after a couple of days is placed in the indoor at normal temperatures maintenance 3-4 days demoulding under normal temperature laboratory after the demoulding.

Certainly, its filler can not be a foamed plastics also, but must be the material of suitable this series products, and this is produced also in protection scope of the present invention.

When producing decorative layer with this invention, several composition of raw materials are cement: filler: the chemical industry auxiliary material: pigment=1: 1～1.5: 0.02～0.03: 0.01～0.03, can do suitably to adjust according to actual conditions.Add suitable quantity of water furnishing pasty state after the uniform mixing, stir again, then injection molding.

Cement can be selected white cement, ordinary cement, alumina cement etc. for use.

Filler can be selected one or more mixtures in the materials such as quartz sand, common river sand, mountain sand, extra large sand, color sand, slag, calcite particle, white marble particle for use.

The chemical industry auxiliary material optional with brightener, strengthen a kind of in the materials such as optical brightener, catalyst, promoter.

For reducing cost, in the decorative layer batching, can add the talcum powder of total amount 3%～6% etc. in addition.

If production white in finish piece, cement then should be selected white cement for use in the decorative layer batching, and pigment adopts titanium dioxide etc.
