Abstract

The invention relates to a product design of monolithic cast straw core non-render concrete block which comprises the following steps: preparing die, filling-in pad, casting concrete, intensifying, modulating, demolding and yielding. It has the following characters: straw core of block has been compressed and shaped and dearranged at the mold; the method fills the concrete clay of the making wall and making rib into mold after filling the straw core. At the same time, the concrete clay can permeate to the gap between straw cores and tight bond with the steel bar of straw core when casting.

Description

Integrated poured straw core exempts to whitewash the manufacturing process of concrete segment

Technical field

The invention belongs to the building construction technology field, concrete is the manufacturing process that a kind of integrated poured straw core exempts to whitewash concrete segment.

Background technology

It is a kind of novel building building block that integrated poured straw core exempts to whitewash concrete segment, its production technology has been continued to use the main technique of normal concrete building block, prepare, insert filler, cast concrete, closely knit, the maintenance demoulding as mould, up to producing finished product, but owing to added straw core in this building block, so existing technology can not satisfy the requirement of this novel building building block fully, a kind of corresponding new production technology is proposed, then be necessary.

Summary of the invention

The present invention's purpose just is to provide a kind of new production technology, and to satisfy the requirement of this novel building building block, promptly a kind of integrated poured straw core exempts to whitewash the manufacturing process of concrete segment.

The object of the present invention is achieved like this: a kind of integrated poured straw core exempts to whitewash the manufacturing process of concrete segment, comprise: filler, cast concrete, closely knit, the maintenance demoulding are prepared, inserted to mould, up to producing finished product, it is characterized in that: the straw core in the building block is in advance through overcompression and be shaped into piece, and such straw core is put into the concrete casting that just will make wall and rib behind the mould in advance and injected mould.Through such technical process, the intensity of straw core and the accuracy of present position have been guaranteed, even the adding of straw core is not only as a kind of filler, and can increase the intensity of building block, be shaped into piece the straw core present position accurately, the became uneven that can prevent concrete wall and rib is even, and this also is in order to guarantee the intensity of building block; Simultaneously, when pouring into a mould like this, the mortar in its concrete can permeate among the gap of straw core, and in building block inside, the contact-making surface of straw core and wall, rib inwall is irregular geometry, and this has just further increased the intensity of building block.In order to improve the efficient of this building block in work progress, before cast concrete in mould, can in another little mould, adopt the superficial layer of two outer walls of cement mortar cast building block in advance, thereby make the surface of two outer walls of building block very smooth and attractive in appearance, to omit or to reduce the workload of whitewashing of wall in the construction.So just realized purpose of the present invention.

The specific embodiment

Master operation among the present invention comprises: mould prepares, pours into a mould that wall layer, stalk compression are shaped into piece, insert mould in another little mould, location, cast concrete, closely knit, the demoulding, maintenance, finished product, and the basic order of these operations is as follows:

Specifically operation is such: it is that straw core adopts mechanization production to carry out that the stalk compression is shaped into piece, and finish at first, after being ready to, enough straw cores can carry out next step operation, the straw core that this compression is shaped into piece is cuboid, adopt mould or anchor clamps to carry out the high pressure compression, and adopt reinforcing bar to tie up typing.The forming wall surface layer also is should be well found for a long time, promptly adopts cement mortar to pour into a mould wall layer in advance in another little mould, wait then take out after the wall layer moulding stand-by.Ready prepd straw core in front and wall layer will be put in the ready mould, straw core and wall layer must be put into mould locatees exactly---and cause the concrete wall poured into a mould or rib to produce became uneven to prevent their deflections even, and its intensity is lowered.Cast concrete in mould immediately then, these concrete will be combined into an integral body fully with the wall layer with the cement mortar cast, obviously, these concrete are in the wall and rib that form building block, its mortar that flows will go along with the pressure of cast and vibration are penetrated in the space that they can be penetrated into---mainly be the inner straw core of building block and the contact-making surface of wall, rib inwall, make concrete and tie up the reinforcing bar of straw core, 4 faying faces of straw core are combined into as a whole tightly.The operation of following closely knit, the demoulding maintenance of carrying out, finished product and so on all be during the normal concrete building block is produced must and ripe operation.

Can see from top said technical process, the building block of producing according to such method, guaranteed combining closely of straw core and wall and rib, just improved the intensity of building block through the highdensity straw core of overcompression itself, add its reinforcing bar of tying up and combine, further improved the intensity of building block with concrete.That so such building block not only has is energy-conservation, sound insulation, heat insulation, light and handy, utilize discarded advantages such as stalk resource, and can improve block strength.Simultaneously, owing to adopt cement mortar to pour into a mould two wall layers of building block, omit or reduce the workload of whitewashing of wall in the construction so can guarantee its wall surface can reach smooth, from and have the time and labour saving of building by laying bricks or stones, an advantage such as easy to use.

Claims

1, a kind of integrated poured straw core manufacturing process of exempting to whitewash concrete segment, comprise: filler, cast concrete, closely knit, the maintenance demoulding are prepared, inserted to mould, up to producing finished product, it is characterized in that: the straw core in the building block is in advance through overcompression and be shaped into piece, and such straw core is put into the concrete casting that just will make wall and rib behind the mould in advance and injected mould.

2, manufacturing process according to claim 1 is characterized in that: before cast concrete in mould, can adopt the superficial layer of two outer walls of cement mortar cast building block in advance in another little mould.
