Abstract

A kind of sandwich building block that has the neutral surface structure, its manufacture method is to make the building-block shell of wall rib with glass reinforced concrete, and make the high-strength sandwich building block of light weight at hollow position filling industrial residue such as flyash, ore deposit slag etc., substitute for clay brick in a large number, to builing industry provide build by laying bricks or stones conveniently, materials for wall with low cost and normalized.

Description

The present invention is that a kind of body of wall of builing industry is laid bricks and manufacture method, and it is to be the sandwich building block of neutral surface structure with the wall rib.

Now, the builing industry materials for wall is still based on loam brick, and along with science and technology development, block brick, various building-block have begun to be applied.Existing lightweight walling unit such as air-entrained concrete building block, fly ash building block are not only produced expensive big, building block cost height, and can not make bearing wall material.And building-block, as patent EP0030510, the building-block that EP0115090 and CN85202454 invented, although when design, considered connection or masonry way, but, hollow end face (no matter being horizontal pass or vertical pass) mortar influences wall quality owing to being difficult for tangling, carry, stack also inconvenience simultaneously, also can only make non-lbearing wall material.With the wall rib is that the sandwich block profile of neutral surface structure is hexahedron setting building block, builds by laying bricks or stones, loads and transports, stacks all superior than building-block; Its wall rib is owing to adopt glass reinforced concrete to make, and light weight is firm.Hollow parts is the sandwich material of filling and form the sandwich building block of an integral body again, and load-bearing, fracture resistance are better than building-block and existing aerated-block.This sandwich building block manufacture method is easy, and small investment not only can utilize industrial residue such as flyash, slag etc. in a large number, and building block is with low cost, and is suitable with loam brick.

The present invention utilizes " the standing tree top is very heavy " principle, makes wall rib building-block shell with glass reinforced concrete, and as neutral surface, obtaining profile in the sandwich material of hollow position filling and the upper and lower end face of sealing building-block shell admittedly then is hexahedral sandwich building block with the wall rib.

With the wall rib is that the sandwich building block such as the accompanying drawing of neutral surface structure illustrated.It reaches up and down by building-block shell (1), sandwich material (2), and two cappings (3) constitute.

(1) is building-block shell in the accompanying drawing, and it is the building-block shell made from glass reinforced concrete that has wall and rib, and its wall and rib are divided into housing the hollow parts of some (being two at least) polygons or hole shape;

(2) are sandwich materials in the accompanying drawing, and it mainly is industrial residue or other special material such as heat insulating materials etc. such as clay or flyash, slag, and add the inorganic material or the macromolecular material that can play the effect of sticking group in above material;

(3) are two cappings up and down of sandwich building-block shell in the accompanying drawing, and it is to make with glass reinforced concrete.It and sandwich building-block shell are irritated casting when moulding or die casting is sealed admittedly, also can bonding solid envelope.

Take the sandwich block of wall rib as the neutral surface structure, its manufacture method is:

1, glass fibre, cement, sand, water are mixed and fill with casting or mechanical die casting in the wall rib die cavity of mould;

2, withdrawing from fuse, is that filling is mixed with other industrial residue or special materials such as the clay of inorganic material or macromolecular material or flyash at the sandwich material of hollow position filling;

3, consolidate two end faces up and down of binder heart building-block shell again with above-mentioned 1 glass reinforced concrete;

4, the demoulding and maintenance.

Embodiment: make the sandwich building block of 600 * 300 * 200m/m flyash.

Production technology is:

(1) at cement: sand: water=add glass fiber in 1: 1.5: 0.2, with its uniform mixing, irritate and cast onto in the preprepared mould compacting wall flank;

(2) withdraw from fuse, be mixed with the flyash and the compacting of lime putty water in the filling of hollow position;

(3) with an end face of the solid binder heart building-block shell of above-mentioned (1) glass reinforced concrete.And hold this end face with template;

(4) the entire die example is put, use another end face of the solid binder heart building-block shell of above-mentioned (1) glass reinforced concrete again;

(5) demoulding and maintenance after the initial set.

Building block of the present invention with mechanical compaction production can raise the efficiency, specification is neat, steady quality.Building block specification determines that by the requirement of builing industry brick-building art wall rib structure form can be selected to determine according to building block size and load-bearing state.

Claims

1, a kind of building wall block and manufacture method thereof, it is characterized in that a kind of is that neutral surface structure, profile are hexahedral sandwich building blocks with the wall rib, and it is to make the building-block shell (1), the hollow parts that have wall and rib by glass reinforced concrete to be filled with sandwich material (2) and to seal building-block shell two cappings (3) formation up and down admittedly with glass reinforced concrete.Its manufacture method is:

One, glass fiber, cement, sand, water are mixed and irritate casting or mechanical die casting in the wall rib die cavity of mould;

Two, withdraw from fuse, at the sandwich material of hollow parts filling;

Three, seal two end faces up and down of building-block shell more admittedly with above-mentioned one glass reinforced concrete;

2, sandwich building block as claimed in claim 1 is characterized in that sandwich material is to be mixed with other industrial residue or special materials such as the clay of inorganic material or macromolecular material or flyash;

3, sandwich building block as claimed in claim 1 is characterized in that the building-block shell made with glass reinforced concrete, and its wall and rib are divided into housing the hollow parts of at least two polygons or hole shape.
