Abstract

The utility model discloses a render-free concrete building block with integrally poured straw core, comprising a wall, a rib, and a core; The render-free concrete building block with integrally poured straw core is characterized in that the core is a compressed shaped straw block which is put into a die and then poured by concrete to make sand pulp in the concrete impregnate into the clearance of the straw block with the pressure and vibration, and thus the contact surface of the core, the wall and the inner wall of the rib can be made into uneven geometric shape; the straw core is a compressed shaped straw block, the straw core has definite intensity, and the sand pulp is impregnated into the clearance of the straw core by pressure and vibration and tightly combined with steel bars which tie up the straw core, and thus the intensity of the building blocks can be improved. The building blocks generally adopt dies made of sheet material, and therefore, the external surface of the building block walls or the future wall surface is made into smooth flat surface or directly made into convex streaks for decoration.

Description

Integrated poured straw core exempts to whitewash concrete block

Technical field

The utility model belongs to the building construction technology field, and concrete is that a kind of integrated poured straw core exempts to whitewash concrete block.

Background technology

Concrete hollow block is a kind of in light weight, build New Building Materials easily by laying bricks or stones, along with its appearance, now there have been some to add the building block of light filler, as the building block of concrete coal dust ash, the building block of concrete expanded perlite, concrete stalk building block or the like, these new type blocks have different a little advantages, but they have a common deficiency, after adding these fillers, its intensity is decreased exactly, in order to remedy and prevent that this possibility from producing harmful effect in practice, so in the time of generally need and making building block in design, the thickness that increases wall and rib is guaranteed its intensity, so just must increase the weight of building block, the cost that has increased transportation and made, and also often unsatisfactory in actual applications.

Summary of the invention

The purpose of the utility model provides with the top building block that is added with light filler with regard to being to remedy the deficiency of above technology has same advantage, can guarantee again simultaneously its intensity, and a kind of integrated poured straw core that can improve efficiency of construction exempt to whitewash concrete block.

The purpose of this utility model is achieved in that a kind of integrated poured straw core exempts to whitewash concrete block, comprise left wall (1), right wall (2), rib (3), core (4), it is characterized in that: core (4) is a stalk piece through the overcompression typing, after putting it into mould, carry out concrete pouring again, mortar in the concrete is gone along with pressure and vibration are penetrated in the gap of stalk piece, thereby make the core (4) and the contact surface of left wall (1), right wall (2), rib (3) inwall be irregular geometry.Just because of this straw core is the stalk piece of finalizing the design through overcompression, itself just has certain intensity, add mortar and be by pressure and vibration and be penetrated among the gap of straw core, and combine closely with the reinforcing bar of tying up straw core, institute is so that the intensity of building block has obtained raising greatly.

Because this building block generally is the mould that adopts sheet material system, so can be that wall surface is in the future made smooth plane or directly made the ornamental striped of projection with the external surface of the left wall (1) of building block, right wall (2).

So just realized the purpose of this utility model.

Description of drawings

Fig. 1 is a front view of the present utility model (analysing and observe).

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the A-A sectional view of Fig. 1.

Among the figure: 1. left wall, 2. right wall, 3. rib, 4. core.

The specific embodiment

In specific implementation process of the present utility model, must relate to its manufacture method, can clearly understand in order to make people, so in the narration process, will add necessary production process.

As shown in the figure, the utility model comprises left wall (1), right wall (2), rib (3), core (4), these two walls and rib are the basic structure parts (" Normal concrete small hollow block " national standard---GB 8239-1997) of ordinary concrete building block, it should also have one " core " in fact, but it is hollow " core ", and " core " in the utility model has not been hollow, so its feature just is:

The first, core (4) is a stalk piece through the overcompression typing, i.e. " straw core ".The manufacturing of straw core is to adopt mechanization mass-produced in advance, be about to stalk arrangement, compression, typing, become " the stalk piece " of a cuboid at last, here as can be seen, straw core through the excess pressure compression will be a highdensity solid matter, simultaneously, need be fixed into " the stalk piece " of a cuboid, then must adopt reinforcing bar that it is tied up, so straw core itself has certain intensity, its adding not only has the advantage of general light filler, and has improved the intensity of building block greatly.

Second, this straw core is not to make back " plug " at concrete block to enter that hollow space and go, carry out concrete pouring behind the mould again but put it in advance, mortar in concrete when this just makes cast can and vibrate in the gap that is penetrated into the stalk piece and go inevitably along with pressure, and combine closely with the reinforcing bar of tying up straw core, consequently make core (4) and left wall (1), right wall (2), the contact surface of rib (3) inwall is irregular geometry, make straw core, reinforcing bar, concrete wall and rib are combined into as a whole, effect then is that the overall performance of straw core is improved, make between straw core and wall and the rib combine more firm, the overall performance of building block also is improved, thereby makes the intensity of building block obtain further raising.

Because this building block generally is the mould that adopts sheet material system, so can be that wall surface is in the future made smooth plane or directly made the ornamental striped of projection with the external surface of the left wall (1) of building block, right wall (2).Here the manufacture method that relates to is to adopt cement mortar to pour into a mould the very thin wall layer of one deck in advance on the mould of sheet material system, when the wall layer of this cement mortar does not also solidify, the just wall and the rib of fluid concrete immediately, make the wall layer of this cement mortar become the external surface of concrete wall, because the cement mortar particle is thinner, so the surface course of its formation is a smoother, this can omit in construction or reduce and whitewash operation.

Claims

1, a kind of integrated poured straw core exempts to whitewash concrete block, comprise left wall (1), right wall (2), rib (3), core (4), it is characterized in that: core (4) is a stalk piece through overcompression typing, and the contact surface of core (4) and left wall (1), right wall (2), rib (3) inwall is irregular geometry.

2, concrete block according to claim 1 is characterized in that: the external surface of said left wall (1), right wall (2) can be the striped that projection also can be made in smooth plane.
