Abstract

A method for manufacturing the colour building block of concrete includes such steps as pouring a concrete layer on the mould bottom, vibrating, putting foam plastic blocks linked by reinforcing bars is the mould, pouring concrete, vibrating, smoothing, curing, demoulding and spraying colour on surfaces. Its advantages are gay colour, high strength and good insulating function.

Description

A kind of production method of colour concrete building blocks

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

The colour concrete building blocks that uses in the current architectural engineering adds that by block machine auxiliary equipment produces, and its equipment investment is big, does not wait to up to a million from hundreds of thousands.And building block once moulding on make-up machine in process of production, not maintenance in mould makes the coarse out-of-flatness of its finished surface smooth, and the physical dimension deviation is bigger.Because reason is not gone into fillers such as foamed plastics in process of production, its building block does not possess incubation and thermal insulation function.

The American has invented a kind of technology of inserting foamed plastics in colour concrete building blocks, still is to insert in the hole behind block forming, does not constitute an integral body with building block.

The purpose of this invention is to provide a kind of surfacing, its investment of production equipment is little, and production cost is low, has the colour concrete building blocks of function of heat insulation.

To achieve these goals, the present invention adopts physical dimension to meet standard, the mould that surfacing is smooth.At first the concrete that stirs at mold bottom cast one deck adopts bobbing machine jolt ramming.Then two blocks of foamed plastics are linked with reinforcing bar, put in this mould.At mould internal pore part cast concrete, it is also manually floating with bobbing machine jolt ramming to fill with the back, and the spary decorative layer just gets product after the maintenance demoulding.

The filler that uses among the present invention can not be a foamed plastics also, is other article, but this series products that should suit.

Foamed plastics among the present invention also can be polylith and can connect without reinforcing bar, reaches related standards but prerequisite is resistance to compression, the rupture strength that must guarantee the building block of production.

Concrete among the present invention also can mix an amount of industrial residue (as one or more mixtures of flyash, gangue, kiln ash, slag, slag, lime etc.).But consumption should suit, and can not influence the cementing strength of cement.

Vibratory equipment among the present invention also can change pressurized equipment into.

The present invention also can adopt a kind of equipment.Earlier mould is fixed on vibration or the pressurized equipment, the positioner of employing activity is put into mould with filler by the position that pre-sets, again cast concrete.After pouring, the movable property of use device is taken out this device in mould, and vibration or pressurization make concrete compaction again.

In the present invention, the true qualities concrete segment of producing can be not painted earlier yet, transport to the job site after, first construction back spary decorative layer.

Produce colour concrete building blocks with this kind method, equipment investment is few, and vibratory equipment adds that mixing plant 4-5 both can produce for thousand yuan.The block surfaces flatness of producing is higher.And its mold bottom can design different patterns, and therefore the concrete segment picture on surface color of producing in this way is colourful, can satisfy requirements of different users.

Link foamed plastics well because this invention has been imbedded with reinforcing bar in concrete, make concrete segment have incubation and thermal insulation function, block strength is improved.

Below, the present invention is further detailed explanation for the specific embodiment in conjunction with the accompanying drawings.

Fig. 1 is the cutaway view after cast one layer concrete and the jolt ramming earlier in mould.

Fig. 2 links cutaway view behind the good foamed plastics for putting in advance with reinforcing bar in mould.

Fig. 3 is gap cast concrete in mould and the jolt ramming cutaway view after floating.

Fig. 4 is the floor map of the block surfaces spary decorative layer after the demoulding.

Earlier pour into a mould a layer concrete 1 as shown in Figure 1, be placed on jolt ramming on the shaking platform then at mold bottom.As adopt punching block, swage then must in mould, brush one deck releasing agent in advance.Concrete grade intensity, preparation according to the pertinent regulations of state.How much that measures should be the wall thickness basically identical (about 30mm) of its thickness after jolt ramming and ordinary concrete building-block.

Shown in Figure 2, in mould, put into the prior polystyrene foam plastics 2 and 3 that connects with reinforcing bar 4, the size of foam-plastic blocks should with the hole size basically identical of ordinary concrete building block.(should be the square about length of side 128mm).The distance of two blocks of foamed plastics is available manually regulates, should be with the rib of ordinary concrete building block thick basically identical (about 35mm-45mm).

Shown in Figure 3ly pin foam-plastic blocks with hand, fill up with same batch concrete 5 in the gap of mould and exceed mould a little, be placed on jolt ramming on the vibratory equipment, manually floating then.Insufficient section can increase again.But the just demoulding about maintenance 2-3 days under nature.Concrete building block after the demoulding can continue artificial or natural curing.

Shown in Figure 4, on the concrete segment surface, promptly build by laying bricks or stones the surface with technologies such as spray gun or artificial brushings with decorative layer 6 sparies on its surface.(decorative layer is the strong exterior coating of resistance to water weatherability weathering resistance corrosion resistance, special-purpose wall paint etc.).And dry the sale of just can dispatching from the factory in maintenance 2-3 days indoor.

Produce colour concrete building blocks with this kind method, in its concrete, can according to circumstances add a certain amount of auxiliary chemicals.(as early strength agent etc.).All can add so long as adapt to concrete auxiliary chemicals.
