Description

Mortar forming system by means of the contemporaneous action of compression, vibrations and vacuum}

The present invention relates to a method and apparatus for manufacturing a cement product (hereinafter referred to as terrazzo ") processed in the form of a single-layer tile slab or slab, and more particularly, uniformly made granulated stone distributed in the terrazzo The present invention relates to a mortar compaction and degassing apparatus for terrazzo molding, which can pressurize and spread the mortar to significantly reduce the pores or bubbles appearing on the surface of the terrazzo, and can greatly improve the physical properties of the terrazzo.

Until the development of artificial marble or granite of cement, the raw stone of natural stone is cut to a certain thickness and size to make slabs, and the surface of the slab is polished and then used as building material for building exterior wall or wall or floor covering. Mainly used, there are marble slabs and granite slabs depending on the material.

Various slabs used for the above-mentioned applications have recently been widely used terrazzo molded products using artificial marble or artificial granite materials due to depletion of natural resources, destruction and pollution of the environment due to quarrying, and expensive manufacturing costs. have.

Terrazzo is a granulated stone sculpted from Portlanddo cement with water granules processed from natural marble or granite sheet or related products in a wide range from 0.1 to 8 mm in diameter. It refers to slabs or blocks made by filling mortar into molds or other molded products manufactured by the above method.

The terrazzo method is mainly manufactured by wet mortar (wet mortar) method. The wet mortar manufacturing method is a method of preparing a mixture of granules and granules in the manufacturing and molding of marble and granite. Exhaust, such as bubbles, between the water and the mixed raw materials produced during the filling process is a very significant factor in the quality of terrazzo finished products.

In particular, after filling the mold with a mixture of the desired ingredients (hereinafter referred to as "mortar") to prepare the terrazo, the thickness of the mortar is compacted to minimize the voids between the solid particles present in the mortar. As a technique for this purpose, Korean Patent Publication No. 93-009330 (priority claim Japanese fire-extinguishing 59-31805 [1984.2.22]) includes the "method of manufacturing high strength cement products".

The feature of the manufacturing method of the high strength cement product proposed in the above-mentioned Patent Publication No. 93-009330 is to extract the excess water of air or foam present in the mortar to increase the quality of the terrazzo, and to make the density of the mortar as compact as possible. Although the filling is introduced, the terrazzo product manufactured by the above technique has a certain amount of pores, so the strength is insufficient, and the bending strength is considerably lower than the theoretical strength of the cement (bending strength of 470kgf / ㎠). There is a disadvantage that can be produced only about 100kgf / ㎠.

In addition, Korean Patent No. 10-0624698 (September 8, 2006) proposes a wet mortar manufacturing method using a terrazzo manufacturing method, wherein the wet mortar method is applied to increase the strength and formability of the terrazzo. And the vibration of the mold and the high air pressure applied to remove moisture cracks and breaks on the floor covering tiles, there is a problem that it is difficult to produce a good quality product with the appearance of cement residue on the tile surface.

In addition, US Pat. No. 4,698,010 discloses techniques related to the manufacture and manufacture of cement shaped articles comprising natural stone granules and binders of various particle sizes.

United States patents,

An initial mixing step of mixing the mortar including the stone and the binder in powder or granule form under vacuum;

Transferring the mixed mortar to a mold (hereinafter referred to as a mold) and vibrating to distribute the mortar uniformly in the mold under vacuum;

It is also characterized by consisting of the step of moving the mold into the chamber under vacuum to squeeze the mortar by vibrating movement of the predetermined frequency.

In addition, as a method for manufacturing a terrazzo molded product which is commonly practiced in Korea, Korean Patent No. 10-0472780, "Manufacturing method and apparatus and manufactured product of cement slab product" is very useful. Technical features of Korean Patent No. 10-0472780,

(a) providing particles of inert granulated natural stone as starting material;

(b) calculating the void ratio of the starting material and calculating the volume of theoretical cement matrix binder sufficient to fill the voids and gaps of the inert granulated natural stone from the calculated void ratio;

(c) preparing a cement matrix binder comprising water and cement having a water content of 0.25 to 0.36 parts by weight relative to the weight of the cement, wherein the cement matrix binder has a very round shape having a diameter of 20 cm when subjected to a mini slump test. Supplementing the mortar with a known plasticizing additive for cement mortar so as to have flowability such that it is arranged in a thin layer;

(d) thoroughly mixing a volume of cement matrix binder in an excess volume of 10% relative to the porosity ratio of the inert granulated natural stone and the precalculated inert granulated natural stone to obtain a mixture;

(e) diffusing the resulting mixture into a forming apparatus to form the required thickness layer;

(f) introducing the forming apparatus to conditions under vacuum with a residual pressure of at least 40 mmHg to obtain a degassing layer of the mixture to degas substantially completely and remove all remaining air;

(g) applying vibratory motion to the degassed layer of the mixture in the molding apparatus at a frequency of 2000 to 4800 cycles per minute for 10 seconds to 3 minutes, the molding apparatus being maintained under vacuum in the range of 70 to 80 mmHg to inert the degassed layer. Compacting the granulated natural stone particles and preventing the surface of the degassed layer from boiling;

(h) conveying the molding apparatus to the solidification and initial cure zone of the mixture; And

(i) separating the cement product from the forming apparatus and holding the same product on the shelf until it is fully cured.

One of the features identified in the conventional terrazzo production method, which has been studied and developed in various ways as described above, is to mix mortar mixtures under vacuum, to remove pores, bubbles, and moisture present in the mortar under vacuum, and in the air. It is a method to realize mortar compaction and mortar diffusion by alternating a mortar-filled mold.

However, the problem of the mortar compaction method filled in the mold as described above is that the granular stone having a relatively large particle gathers toward the edge of the mold in the process of flat spreading of the mortar with fluidity due to the alternating motion (vibration) of the mold. For example, mortar mixed components with relatively small particles gather at the center of the mold.

Problems derived from this phenomenon cause very many problems for terrazzo.

The most common problem is that the distribution of granulated stone in mortar is concentrated only at the edge of the mold, so that the physical condition of the terrizo such as surface strength, impact strength, flexural strength and breaking strength is reduced, as well as the decrease in adhesive strength between granular stones. Less than terrazzo is generated, and the stone texture expected from the granulated stone selected as a mortar component is not obtained, and the edge or edge of the edge or edge of the terrazzo when the finished terrazzo is packaged, transported or constructed. There is a problem that fall occurs.

Therefore, not only the mortar compounding technology according to the manufacture of the terrazzo molded article, but also voids, moisture, or bubbles between the particles present in the mortar adversely affect the quality of the terrazzo, but related techniques for improving the terrazzo are not remarkable.

The main reasons for this reason are the mixing ratio of water or liquid binder in mortar and the chemical reaction of cement binder, viscosity of mortar, curing rate and evaporation of water generated during curing process and boiling of liquid agent added to mortar. This is because it is fundamentally impossible to completely eliminate bubbles or bubbles generated inside the back mortar.

In addition, when manufacturing a special terrazzo, which emphasizes special physical properties, ie, surface strength, impact strength, or bending strength, a small amount of terrazzo having a target physical property is possible by inserting a mesh wire into the mortar, but as described above. The production of terrazzos used for special purposes by the conventional mold vibration method is virtually difficult.

The reason for this is that the steel wire or mesh wire inserted into the mortar by the alternating motion applied to the mold during the mortar compacting is difficult to float on the surface of the mortar or to place the mesh wire in a proper position in the mortar.

As mentioned above, most of the problems in the terrazzo manufacturing method currently used are found in the terrazzo completion stage. Therefore, the cost and time wasted in the terrazzo manufacturing process that has been completed until the completion stage is very large. Development inside is required.

The present invention has been invented to solve the problems associated with terrazzo production as described above, the first object of the present invention is to form elements that form voids or bubbles between the solid particles, particularly in the terrazzo molding mortar. The present invention provides a mortar compaction apparatus for terrazzo molding which vibrates while pressurizing the mortar to effectively degas.

A second object of the present invention is to provide a terazzo molding mortar compaction and degassing apparatus for effectively degassing elements forming pores or pores between solid particles present in the terrazzo molding mortar.

According to the terrazzo molding mortar compaction apparatus according to the first object of the present invention, the space between the particles present in the mortar by vibrating while applying pressure directly to the mortar mixed with the inert granite stone having the desired size and the cement matrix binder And bubbles can be effectively discharged to the outside, prevent the uniform distribution of granulated stone, and physically flatten the mortar to solve all the problems that occur at each corner of the mold, curing It is possible to improve the physical properties of the terrazzo as well as to have a uniform thickness of the molded article, a dense texture of the tissue.

According to the terazzo molding mortar compaction and degassing apparatus according to the second object of the present invention, by vacuuming the mold in a state in which the pressurized vibration of the mortar is maintained, fine pores or air remaining in the mortar can be forcibly degassed and degassed. This can be further improved. Of course, it also has an effect according to the first purpose.

Not only can it effectively release bubbles, bubbles, etc., but the structure of the hardened mortar has a uniform density as a whole, and also can mass-produce high-strength terrazzo with desired physical properties.

Therefore, the generation rate of the poor terrazzo can be innovatively lowered, thereby significantly reducing the manufacturing cost.

[Preferred Embodiment for Mortar Compaction Device]

Referring to Figure 1, Figure 1 is a longitudinal cross-sectional view illustrating a terrazzo molding mortar compaction apparatus according to the present invention, Figure 2 is an extract showing the terrazzo molding mortar compaction apparatus of the present invention shown in FIG. A main cross-sectional view is illustrated.

In the drawing, reference numeral 1 denotes a mold in which a mortar is inserted, and a mold is disposed below the mortar compaction apparatus by a pusher interlocking with a conveyor belt or a hydraulic cylinder, thereby showing a work preparation state.

The preferred embodiment of the terrazzo molding mortar compaction apparatus of the present invention,

Mortar compaction apparatus 100,

A plurality of supports 2 for supporting the fixed plate 10 to be positioned at a predetermined height;

A first actuator 20 attached to the fixed plate 10 and remotely controlled;

A plate-shaped press plate 30 coupled to the first actuator 20 to press the mortar 3 filled in the mold 1 according to the operation of the first actuator 20;

A vibrator 40 coupled to the pressing plate 30 to generate a vibration wave during the pressing operation of the pressing plate 30 to vibrate the pressing plate 30;

The controller 50 is configured to control the first actuator and the vibrator 40 in a circuit.

The first actuator 20 and the controller 50 are controlled by a control logic woven programmatically according to work characteristics.

The control characteristic to be considered in the control logic is the operation holding time of the first actuator 20 and the vibrator 40 for operating the pressing plate 30.

The control logic of the controller 50 may be added to the overall control logic of the automated terrazzo manufacturing apparatus or the control logic of the first actuator 20 may be implemented as a controller (microcom or semiconductor device).

In FIG. 2, two mortar compaction apparatuses 100 are installed corresponding to two molds. However, the mortar compaction apparatus 100 is applied to the pressing plate 30 by the number corresponding to the number of molds 1. Can be installed.

The pressing plate 30 which moves up and down according to the operation of the first actuator 20 may further include a pressure adjusting means 60.

The pressure adjusting means 60 is when the pressing plate 30, which is interlocked with the first actuator 20, presses the surface of the mortar 3, when the amount of mortar is excessively thick or the mortar is too small. This is to cope with the problem that the pressing plate 30 forcibly presses the mortar 3 of the pressing plate 30 or the pressing plate 30 does not reach the mortar 3.

As a preferred embodiment of the pressure adjusting means 60 in the present invention, referring to Figure 3, Figure 3 is an enlarged cross-sectional view showing an enlarged portion A shown in Figure 2, the shaft having a predetermined length on the pressing plate 30 (31) attached to the end of the first actuator 20, the shaft 31 is slidably assembled and assembled so as not to be separated, and connected between the pressing plate 30 and the connecting member It can be implemented as a compression spring (S1) coupled to the shaft (31). In the drawings, reference numeral 22 denotes a shaft 31 that is slidably accommodated and is a friction alleviating member.

As an example of the operation of the pressure adjusting means 60, when the operation of the first actuator 20 is started by the controller 50, the pressing plate 30, which cooperates with it, vibrates and pressurizes the surface of the mortar 3 simultaneously. If the thickness of the mortar 3 is abnormally thick, the pressing plate 30 may continue to operate according to the operating stroke of the first actuator 20 acting on the pressing plate 30 in the stopped state.

When the operating load of the first actuator 20 continues to act on the stationary pressure plate 30, the connecting member 21 is lowered to overcome the elastic force of the compression spring (S1) to absorb the operating load.

On the contrary, in the case where the thickness of the mortar 3 is thin, the pressing plate 30 is formed by the maximum operating distance of the first actuator 20 and the length of the shaft 31 extended by the elastic force of the compression spring S1. By employing a shaft 31 having a length so as to pressurize the surface of the mortar, the mortar 3 can be pressed.

Therefore, the mortar compaction apparatus 100 according to the present invention is operated by the controller 50 while the vibrator 40 is operated at the same time while the first actuator 20 is operated so that the pressing plate 30 presses the mortar 3. As the vibration wave is transmitted to the surface of the mortar, the pressing plate 30 may compact and diffuse the mortar 3 having fluidity at an appropriate pressure by the extension length of the first actuator 20 and the elastic force of the compression spring S1.

Unlike the conventional method of vibrating the mold 1, the embodiment according to the first object of the present invention does not fundamentally cause a problem that the mortar surface layer is compressed so that the granular particles are collected toward the edge of the mortar 3, as well as the compressive force. The interstitial pores or bubbles present in the mortar 3 can be released out of the mortar 3, and the mortar 3 is formed by a mold (by vibrating action of the vibrator 40 and the physical pressure of the plate-shaped pressing plate). Spread evenly on each corner of 1) to form mortar with even thickness.
