Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a plate-shaped material, and more specifically, a method for manufacturing a plate-shaped material, and more specifically, a method of manufacturing a plate-shaped material, a material that hardens over time, concrete formed using reinforcing steel, a plate-shaped material or a fireproof material, and a hardening agent; The present invention relates to a method for manufacturing a plate-like material formed using fine aggregate and a hardening agent.

The coarse/fine aggregates used in the present invention may be selected depending on the intended use. For example, for manhole covers for lifting underground pipes, natural coarse/fine aggregates or mineral slag coarse/fine aggregates may be used. When used in high-temperature areas, such as the lid of a molten metal container such as a torpedo car, ladle, or tundish, or as a covering material for molten metal, foamed perlite, chamotte, alumina, etc. are recommended because they have excellent heat resistance and insulation properties, and are easy to handle and lightweight. Alternatively, a plate material with a long life can be obtained.

The binder that binds and shapes the respective coarse and fine aggregates into a certain shape may be ordinary cement for the former, and heat-resistant mortar for the latter.

In order to provide the impact resistance necessary for these plastic plate-like materials, to stably maintain a predetermined shape, and to prevent damage during handling, etc., as necessary, In addition to the selection of the binder, it is also necessary to embed parts such as reinforcing bars or the like that will become bones in the plastic body.

The present invention provides a method for efficiently manufacturing plate-like materials having shapes such as round, square, or other shapes determined as necessary. The upper and lower members are installed on a frame-like surface plate that is inscribed with the side surface of the material and can be divided perpendicularly to the plate-like surface, or on a base member with an internal iron plate, and the upper and lower members are spaced apart by the thickness of the plate-like material. A reinforcing device consisting of a plurality of spacers holding the spacers and a reinforcing material fixed within the spacing between the spacers and developed into the planar shape of the plate-like material is inserted into the frame, and the reinforcing tool is installed in the frame. A reinforcing tool, a plastic material mixed with coarse and fine aggregate according to the required C2 is injected into the hardening agent up to the upper part of the frame, and then an iron plate whose outer periphery can be contacted with the inner surface of the frame is charged, and then the above-mentioned A board characterized in that the steps after charging the reinforcing tool are repeated until the number of manufactured units is completed to maintain the curing time of the post-curing agent, and then the frame is divided to separate the laid iron board and the plate-like material. It is in the preparation method of shaped materials.

An embodiment of the present invention will be described below with reference to the drawings.

2(a) and 2(b) show the iron plate 4, in which (a) is a plan view and (b) is a side view. In this example, an iron plate with a thickness of 2M is used.

Figures 3 (a) and 3 (b) show the divisible frame 5 placed on the base material 9 (a) is a plan view, and (b) is (a
In the -A side sectional view, the frame 5 consists of an outer plate G frame reinforcement 7, a divided part J''+ 6, and a connecting bolt/nut 8, and a locking tool 10 removably installed on the base material 9 is attached to the reliquary 9. is held in
The height h is a dimension necessary for the unit number of plate-shaped materials P manufactured.

When placing the frame 5 on the reliquary 9, the iron plate 4 may be inserted into the frame 5 after it is placed, leaving some space outside the outer periphery of the frame 5 before placing it. An iron plate (not shown) is placed, the frame 5 is placed on top of the iron plate, and the base material 9C is inserted through the iron plate.
Two locking devices 10 may be installed.

When the above preparations are completed, the state shown in FIG. 3 is achieved: (1) the reinforcing tool T shown in FIG. 1 is inserted into the frame 5, (2) then the spacer
Up to the upper member 1-rubel, foamed perlite prepared separately and plastic molded with fireproof mortar are injected, (3) the iron plate 4 is charged, and then (3) is repeated for the number of production units. Complete the first step.

After that, after the curing time has elapsed, the bolts and nuts 8 are loosened, the frame 5 is disassembled, the plate material P and the iron plate 4 are separated, and the second step is completed. do.

If further curing or drying is required, the third step is to allow the material to stand for an additional curing period, and then, as the fourth step, drying is carried out naturally or by force as necessary.

In carrying out the present invention, the frame body 5 may be divided by a bolt/nut method, or by a hinge or a locking bolt (a method in which one dividing point 6 is used as a hinge, and the other dividing point 6 is sewn and locked with a locking bolt). The frame 9 may also be used as a bottom member during product transportation, and in this case, the frame 5 may be convertible into a packaging frame (not shown) for handling.

The above example describes 1. a method for manufacturing a round plate material for a lid for a molten metal container such as a peed car or cast iron, and a plate material for a manhole using cement mixed with fine and coarse aggregates. wood,
Furthermore, even if the material of the plastic material changes and the shape of the frame changes for other square plate materials for coating molten metal in the tundish, as well as triangular, hexagonal, and octagonal plates, the manufacturing method will still be the same as described above. As in the example, 'pζl1ilj can be used.

According to the present invention as described above, it is possible to handle plate-like materials of the same shape in a narrow space and handle raw materials in a single manner.1. −(i
It can be manufactured easily, and the labor and time required for manufacturing can be greatly reduced, resulting in lower manufacturing costs, stable product quality,
Great effects can be obtained in terms of ease of handling, workability, productivity, and economy.
