Abstract

A technology for producing the building block of concrete includes such steps as pouring a decorative layer on the bottom of mould, putting a locator with the embedded objects in the mould, pouring concrete in the mould, vibrating or pressing, taking the embedded objects out by said locator to form holes, filling form plastics in the holes, pouring concrete again, vibrating or pressing, curing and demoulding.

Description

A kind of production method of new concrete building block

The present invention relates to the production method of the concrete segment that uses in a kind of architectural engineering.

As the concrete segment production method of materials for wall, be to adopt drawing method production in the current architectural engineering by block machine.This mode of production equipment investment is big, and product is because the short surface ratio of molding time is more coarse.Adopt independent die casting production building block, owing to do not use positioner yet, but fillers such as foamed plastics are directly put into concrete surface, such mode of production makes the wall thickness of building block and reins in thick can not being consistent, be unfavorable for the stable of product quality, and filler such as foamed plastics can only service regeulations block, and serve as filler after can't using discarded foamed plastics to pulverize.

Produce the new concrete building block by the present invention, be in mould, to pour into a mould one deck decorative layer earlier, by vibration or the positioner set up of pressurized equipment mould is fixed on certain position then, and then the positioner of the activity by connecting insert is put insert in the mould into by the position of design in advance.The size shape of insert should with the hole basically identical of normal concrete building block.And then at mould gap cast concrete, the mould gap is filled with, utilize vibration or pressurized equipment to make it closely knit.Positioner by activity takes out insert in mould then.In the hole of its formation, insert foamed plastics again.Hole is filled up, then cast concrete for the second time.Water fill with mould and make concrete exceed mould a little, again with the vibration or pressurized equipment make its closely knit moulding, become product after the maintenance demoulding.

By the concrete segment that above method is produced, the wall thickness that can make building block when producing in batches thickly remains to consistently with reining in, and the quality of building block has reduced randomness when having guaranteed batch process.And can use a large amount of discarded foamed plastics.Help reducing cost and twice laid.

Produce concrete segment with this method, also can not pour into a mould decorative layer earlier, directly cast concrete in mould utilizes aforesaid way to produce the true qualities building block, again at its surface spraying and decorating layer.Or transport to and carry out the appearance decoration after site operation is installed.

If foamed plastics is that the block reinforcing bar that also can adopt couples together them earlier in upper type, insert in the hole again.Insert can do also that to grow into two hole sum Galles thick in, wide the wide rectangle of hole.If filler is chunky shape or broken foam shape, then insert should be designed to convex, and the filler quantity of inserting when producing can be determined according to pre-designed position.

Can add color sand in the production in the decorative layer prescription, demoulding rear surface can and be polished with the grinding machine polishing.

The concrete of pouring into a mould in the production can mix an amount of industrial residue (as: flyash, gangue, slag, kiln ash, lime, slag etc.), lightweight aggregate (haydite, pottery sand, expanded perlite, Peng Zhang Chi stone, shale, scoria, float stone, cinder etc.), additive (early strength agent etc.).

Produce the mould of this kind building block and can use mould of plastics, composite material mould, swage, punching block etc.The insert material should be that hard is high-strength.As steel etc.

Fig. 1 is the cutaway view after pouring into a mould decorative layer and making it closely knit.

Fig. 2 is for putting into the cutaway view of insert by the position of design in advance.

Fig. 3 is the cutaway view behind the cast concrete.

Fig. 4 is the cutaway view after vibration or pressurization make it closely knit.

Fig. 5 is for adding the cutaway view of foamed plastics.

Fig. 6 is for cast concrete for the second time and the cutaway view after making it closely knit.

The decorative layer 1 of cast earlier shown in Figure 1.Mould is by the national standard design.The raw material of decorative layer should be mixed in proportion and stirs before the cast.The decorative layer prescription is: white cement: quartz sand: resin (brightener): pigment=1: 1-1.5: 0.02-0.03: 0.01-0.03, ratio can be according to the actual conditions adjustment.Earlier above raw material is stirred, add an amount of furnishing pasty state of water.Cast thickness is 2-5MM, gets rid of bubble through vibration.Placed about one hour on indoor level land then, till feeling to be difficult for squishing with its surface of hand.

The positioner 2 that is connected with insert of putting into shown in Figure 2.The position of insert should be pre-designed.Its position in mould should with the hole location basically identical of ordinary concrete building block.

Shown in Figure 3 at the gap of mould cast concrete 3, mould should be filled with as far as possible.Concrete label is by the requirement preparation of country to the ordinary concrete building block.Dried wetting should be suitable.

Utilization vibration shown in Figure 4 or pressurized equipment vibrate it or pressurize, and make it closely knit.

Shown in Figure 5, the head by positioning equipment takes out insert in mould.Just two shape sizes and the basic the same hole of ordinary concrete building block have been formed like this in the concrete.In its hole, foam-plastic blocks 4 and 5 is filled up again.

Shown in Figure 6, continue second batch of concrete 6 of cast on the top of mould, mould is filled up and exceed mould a little.Adopt vibration or pressurized equipment to make its closely knit moulding.But the just demoulding after maintenance 3-5 days under the normal temperature laboratory continues under normal temperature laboratory the maintenance sale of just can dispatching from the factory about 10 days after the demoulding.

In addition, in order to improve product quality and production efficiency better, can on the said equipment and production technology, to carry out computer and improve automatically.Can adopt computer to all around position of positioner insert in mould, each cast concrete amount what, put into the filler amount what, the size of volume, at every turn vibration or the length of pressing time, strength size, insert put into take-off time and concrete material prescription, the decorative layer composition of raw materials is controlled.In addition, can utilize automatics to make the putting into and take out and all realize automation, computerized control of conveying, cast and insert of raw material and product.Reach full automation production.
