Description

Technical Field [0001] The present invention relates to an integrated mixing and pouring apparatus for fiber reinforced cement composite material,

More particularly, the present invention relates to a fiber reinforced cement composite material which comprises a cement composite, a blended water, an admixture and a fiber, The present invention relates to an integrated mixing and pouring apparatus and method of a fiber reinforced cement composite material which performs mixing and casting at a time in a self-propelled moving vehicle when a composite material (FRCC) is laid.

Generally, a batch plant mixes cement, sand and various aggregates at a certain ratio and then mixes with water to produce ready mixed concrete, which is then transferred to a remicon vehicle and supplied to the workplace. At this time, the batch plant has respective hoppers for storing or supplying cement, sand, various aggregates, and the like.

Also, in the batch plant, the amount to be mixed is weighed using each hopper and then transferred to a blender. In the blender, additives such as water and an admixture are added according to predetermined conditions and mixed with other materials. Such a batch plant is usually installed adjacent to a construction site, and can be configured to be movable to supply a concrete mixer to a small construction site.

A batch plant constructed in such a movable form allows each component to be disassembled or assembled into a trailer, and each component is disassembled and transported on a trailer when it is moved. When used, each component is assembled to manufacture a ready- This is mainly used.

However, such a batch plant requires a work for assembling the respective components in the process of moving and installing, which makes it difficult to quickly move and work. In addition, there is a concern that the quality of the ready-mix produced according to the assembled state of the batch plant according to the related art may be changed, and there is an inconvenience that separate commissioning is required for stable supply after each component is assembled. In addition, such a batch plant is not only inconvenient because components may be lost or lost in the process of disassembling or assembling each component, and continuous maintenance is required.

Also, since the ready-mixed concrete is mixed with cement, aggregate and compound water in advance, it is transported to the ready-mixed vehicle. Therefore, it is inevitable to dispose of it because it can not be used when the predetermined transportation time is not followed, Has been pointed out.

Therefore, a mobile mixer, which is a portable type mixing equipment that can be used in a precise ratio at a construction site according to a special site situation instead of a concrete mixer according to the conventional technology, is being developed. Such a portable mixer can easily mix raw materials such as cement or aggregate with water and put it in a construction site, and it is convenient to move and install it by a trailer. In other words, such a mobile mixer can produce a target concrete mixture without being restricted by time and place by mounting such a concrete plant in a vehicle.

Accordingly, the mobile mixer vehicle equipped with the mobile mixer can be directly mixed and mixed in the field, for example, after the spray concrete material is transported directly to the installation site. For example, in Korea, such a portable mixer is currently used in small-scale road repair work, and is being used in the production of latex and ultra rapid concrete.

In addition, such a mobile mixer can easily control the quality of concrete materials such as water, cement, aggregate, and admixture required for spraying concrete by directly receiving raw materials directly from the site without using the remicon maker near the site. Further, since the concrete material is directly transported and mixed at the site, there is an advantage that it is not restricted by the accessibility and constructional problems of the mine mentioned above. In addition, such a mobile mixer has a merit in that it can reduce the production cost compared to the use of a concrete mixer factory by producing a small amount of concrete on site.

On the other hand, in the case of spray concrete, reinforcement fibers such as steel fiber and synthetic fiber are additionally mixed to secure flexural strength and flexural toughness. However, in the mobile mixer according to the prior art, there is no development of a fiber mixing device, and when such a fiber reinforcing is required, it is difficult to uniformly input reinforcing fibers and secure quality because it relies on manpower input.

As a prior art for solving the above problems, Korean Patent No. 10-1285090, filed and registered as a patent by the applicant of the present invention, discloses an invention entitled " a steel fiber feed hopper and a mobile mixer equipped with the same, Which will be described with reference to Figs. 1 and 2.

[0034]

Particularly, in the steel fiber feed hopper 20, a twist roller type rotary blade is installed in the steel fiber in consideration of the difficulty in quality control of concrete casting because the amount of the steel fiber is not constant due to the bundling of the steel wires. The steel fiber supply hopper 20 is installed to automatically supply the steel fiber 30 to the mixing auger 13 and the steel fiber 30 discharged from the steel fiber supply hopper 200 is supplied to the mixing auger 13, Conveyed along the conveyor belt 15 to the mixing auger 13 and mixed with other materials.

Steel fiber (30) is a material of steel fiber used in fiber-reinforced mortar or concrete. It is used for improving crack-restraining property, impact resistance, toughness and the like. Normally, steel fiber The steel fibers 30 of about 0.5 mm are uniformly dispersed and incorporated, and the steel fibers 30 are mixed at a mixing ratio of 1.0 to 2.0%.

The conveyor belt 15 for supplying the aggregate is installed to supply aggregate such as coarse aggregate and fine aggregate from the concrete material to the mixing auger 13. The conveyor belt 15 for conveying the steel fiber 30 supplied from the steel fiber feed hopper 20 And supplies it to the mixing auger 13.

The mixing auger 13 is a screw type mixing equipment and mixes concrete materials such as cement, coarse aggregate and fine aggregate with the mixing water provided from the mixing water tank 12. That is, the mixing auger 13 mixes the coarse aggregate, the fine aggregate and the cement supplied from the material storage unit 11, the steel fiber 30 supplied from the steel fiber supply hopper 20, And mixes them.

A control panel (not shown) controls whether or not the aggregate is discharged, the discharge amount, the discharge amount of the cement and the discharge amount, the water supply amount of the compound water tank 12, and the supply amount of the steel fiber 30. The control panel 14 controls the production rate of concrete by metering each material and adjusts the amount of the steel fiber 30 supplied per unit time from the steel fiber supply hopper 20 to a constant amount.

The portable mixer 10 according to the related art is a device for conveniently placing concrete in a vehicle by installing aggregates, cement, sand, water, quick-setting steel, and a steel fiber 30 on the vehicle. In order to improve the entangling of steel fibers, A twin roller type rotary vane is provided to prevent the fiber bundle feeding hopper 20 from being entangled with the fibers and the size of the steel fiber feeding hopper 20 is greatly reduced and the movable fiber feeding hopper 20 is detachably attached to the upper portion of the movable mixer 10 It is possible to reduce the installation time and manpower consumption significantly.

According to the movable mixer 10 equipped with the steel fiber feed hopper according to the conventional technique, by using the rotating blade of the twist roller type, the steel fiber can be uniformly injected into the mobile mixer without tangling, and the steel fiber feed hopper 20 It is possible to automatically and easily supply the steel fiber 30 by easily detaching and attaching the movable mixer 10 and also by using the movable mixer 10 equipped with the steel fiber feed hopper 20, So that it is possible to secure economical efficiency even when a small amount is poured.

However, in the case of the mobile mixer equipped with the steel fiber feed hopper according to the above-described conventional technique, the structure of the steel fiber feed hopper 20 which is limited to the installation of the spray concrete and is detachable and attachable is very complicated, It is not easy to apply the fiber reinforced cement composite material (FRCC).
