Description

[Detailed Description of the Invention] Conventionally, in order to manufacture concrete plates, especially large plates, a room and a curing room are provided for drying and fixing the poured concrete, and a long period of time is required for curing before shipment. Since this requires a curing period, considerable equipment is required, and its maintenance costs are also high, and the product cannot be sold at a low price. After pouring and pouring, the work can be done in that state in the formwork.
The above-mentioned problems have been solved by fixing, curing, and demolding the product so that a strong product can be shipped immediately.

Furthermore, the present invention has been developed to improve the small-sized or mass-produced formwork of the patent application No. 276282 of 1985 for "Formwork body using foam as a heat insulating material" for mass production with large plates. According to No. 276282, the temperature of the concrete rises to 60 degrees or more in about 24 hours, and if this is left as is, the temperature will suddenly exceed 70 degrees, which may cause deterioration of the concrete. was there. In order to avoid this, it is necessary to remove the mold within 24 hours, remove the cover, or move the frames if stacked, which may be a little difficult for mass production. There was a point.

The present invention monitors whether the temperature of the concrete rises above a predetermined temperature when the concrete is stacked in several tiers,
At the same time when the temperature exceeds a certain level, water is sprayed to prevent the temperature from rising, and water curing is also performed to further increase the strength of the concrete, thereby eliminating the above drawbacks. It is excluded.

Referring to the drawings below, one embodiment will be described. Reference numeral 1 denotes a base plate, which has four to an arbitrary number of legs 2, and reinforcing materials 3 are assembled vertically and horizontally in a lattice shape and welded to the upper surface of the material 3. At the same time, a face plate 4 is attached to the back side of the plate 4, and a heat insulating material 5 such as a plastic foam is attached to the back side of the plate 4, leaving a small portion of the surrounding area.

At this time, the base plate 1 is formed into several types of arbitrary sizes and shapes, and the face plate 4 is made by slightly bending the four ends of one plate, and the plate is placed in one or two frames of the reinforcing material 3. Molded by screwing or welding in between.

Reference numeral 6 denotes a heat insulating material, which is exposed entirely or on one side and is covered with a plate 7 for protection.Both ends of the plate 7 are slightly extended and holes 8 are drilled therein. Although not shown, the mouth 8
A U-clip or screw is attached to the base plate 1 to form a frame body 9 having a square shape or an arbitrary shape and also serving as a formwork. It is attached removably on both plates 4 of the.

Reference numeral 11 denotes a patterned plate made of plastic foam or the like which also serves as a heat insulating material.The plate 11 is formed with a desired pattern on its surface and is removably placed on the bottom of the frame 9.

12 is an auxiliary heat insulating material that also serves as a formwork board, and is similar to the above heat insulating material 6.
In the same manner as above, the entire body is covered with a plate 7' for protection. Depending on the thickness of the concrete, it is used by being engaged and attached to the lower part of the heat insulating material 6, and any number of different types can be provided.

The frames 9 and 9' are formed by each heat insulating material 6 and the auxiliary heat insulating material 12. Although not shown, a concrete plate molding formwork is accommodated inside each of the frame bodies 9 and 9'. Although the concrete is poured into the mold, the main frames 9 and 9' can also be used as formwork.

By adjusting the amount of cement put into the frame 9, concrete plates with several predetermined thicknesses can be formed, and by adding the frame 9', it is possible to form concrete plates of several different thicknesses according to your preference. It is possible to form concrete plates.

Numeral 13 is a heat insulating material covered with a plate 7', similar to the heat insulating material 6, which is placed on the back side of the face plate 4 on the lower extension line of each heat insulating material 6 of the frame 9, and its tip is reinforced. Attach it to the back side of the plate 4 so that it protrudes a little more than the plate 3, and attach the frame 9.
' is formed and provided.

Reference numeral 14 denotes a water sprayer having a sensor 15, which is attached to one side of the heat insulating material 13 of the frame 9. Reference numeral 16 denotes a regulator for adjusting the amount of water, which is attached to the side of the other heat insulating material 13.

17 is designed so that the above-mentioned base plate 1 can be stacked in five or several stages, and by stacking, one piece of ■■
This is a greenhouse.

Note that 18 is paste (concrete board), 19 is pin, 2
0 is a hose connected to the water sprayer 14 and a water tank (not shown).

In the above configuration, the paste 18 is injected into the frame 9 of the base plate 1, and the base plates 1 injected into the dovetail frame 9 are left stacked in five stages or any number of layers in the workshop. .

In this way, the temperature gradually rises from about 30° over a period of 4 hours or more, reaches about 60° in about 1 day and 24 hours, and soon exceeds 60° when it is completely dry. Then sensor 1
5 detects this and sprays water from the water sprayer 14 onto the concrete 18 in the greenhouse 17 to lower the temperature to a predetermined temperature, and also performs water curing to further increase the strength of the concrete. It is.

To remove the mold, first remove the mounting plate 10, remove the U-clip or (not shown) of the frame 9, and remove the heat insulating material 6 to expose the concrete plate 18. That's what I do.

In this way, the present invention enables mass production of strong concrete plates that can be dried and cured in the workshop where they are poured in about 4 hours or more and about 1 day and night, and can be shipped directly from the workshop. is also possible.

As described above, the present invention can provide an excellent concrete plate that is easy to assemble and demold, does not require a drying room or a curing room, and is strong even when placed in a workshop and left unattended. Therefore, it has significant effects and characteristics in terms of time and economy.
