Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for manufacturing panels used as cross-type building materials, and particularly relates to a method for manufacturing panels used for diagonal building materials, and in particular, to produce a smooth and beautiful surface even when the manual plastering trowel finishing step is omitted. The present invention relates to a panel manufacturing method capable of efficiently manufacturing a panel having a body.

[Conventional technology]

During the manufacturing process for this type of architectural panel, finishing work using a plastering trowel was required to finish the panel surface. This is because hydraulic mixtures such as gypsum and cement immediately after pouring contain excess air bubbles and excess water, which do not cover rough or uneven surfaces until a certain period of time has elapsed. Naturally, in order to manufacture architectural panels with beautiful surfaces that are smooth and free from irregularities, a manual plastering trowel finishing process was required.

[Problem that the invention seeks to solve]

However, the above-mentioned finishing process with a plastering trowel requires skilled techniques, and when manufacturing a large number of architectural panels, it ultimately requires a great deal of labor and time. Depending on the level of skill involved, there was a good chance that the product would be inconsistent and defective architectural panels would be manufactured that did not necessarily have the required surface finish.

The present invention provides a panel manufacturing method that omit plastering trowel finishing, which can automatically and efficiently manufacture architectural panels with a desired surface finish without requiring a surface finishing process using a plastering trowel. We aim to provide the following.

[Means for solving problems]

The above-mentioned problem arises when the base formwork has an upright wall that is located on the top surface of the base formwork and has a sloped part on the outer periphery, and has a wedge-shaped end that makes line contact with the bottom surface of the base formwork that is located on the upper stage. After pouring a hydraulic mixture such as gypsum and cement into the upright wall of the peripheral formwork, the surface is slightly higher than the edge of the upright wall, and the base formwork is placed on top of this. Or, in the process of gently placing the base formwork with the peripheral formwork on the top surface, excess mixture of hydraulic mixture such as gypsum and cement and air bubbles are brought into line contact with the bottom surface of the base formwork and the peripheral mold. When the base formwork or the base formwork having the peripheral formwork on its upper surface comes into contact with the upper edge of the standing wall of the peripheral formwork,
Method for producing a panel without plastering trowel finishing, characterized in that the upper surface of a hydraulic mixture such as gypsum and cement is brought into tight pressure contact with the lower surface of the base formwork located on the upper surface of the base formwork, and the base formwork is located on the upper surface of this base formwork Peripheral formwork having a standing wall, after pouring a hydraulic mixture such as gypsum and cement into the standing wall of the peripheral formwork, the surface is made slightly higher than the upper edge of the said standing wall; In the process of gently placing the base formwork with the base formwork or the peripheral formwork on the top surface, excess mixture of hydraulic mixtures such as plaster and cement and air bubbles are removed from the bottom surface of the base formwork and the peripheral formwork. In addition to draining water from the gap between the upright walls of the frame, when the base formwork or the base formwork having the peripheral formwork on its upper surface comes into contact with the upper edge of the upright wall of the peripheral formwork, water such as plaster and cement will be discharged. The problem is solved by a method of producing panels without plastering, which is characterized in that the hard mixture top surface is brought into intimate contact with the bottom surface of the base formwork located on the top surface.

〔Example〕

Hereinafter, one embodiment of the present invention will be explained based on the drawings.

In the figure, reference numeral 1 denotes a base formwork, which is made of a flat plate with smooth surfaces on its upper and lower surfaces. 2 is a peripheral formwork, which is the base formwork 1
It has an upright wall portion 2a located on the upper surface of. The end portion 2a+ of the standing wall portion 2a has a wedge shape with an inclined portion on the outer periphery and is in line contact with the lower surface of the base formwork 1 located at the upper stage.

3 is a hydraulic mixture such as gypsum and cement that is poured into the upright wall portion 2a of the peripheral formwork 2 on the base formwork 1; in the present invention, the surface is poured into the upright wall portion 2a. The standing wall portion 2a is cast slightly higher than the top portion 2a'' of the standing wall portion 2a, and is cast slightly higher than the top portion 2a'' of the standing wall portion 2a. Next processed mixture 3
Another base formwork 1 or a base formwork 1 having a peripheral formwork 2 on the top surface is gently placed on the top surface. In this process, excess mixture and air bubbles in the hydraulic mixture 3 such as gypsum and cement are discharged from the bottom surface of the base form 1 and the upright wall 2a top 2a'' of the peripheral form 2. In the invention, the end portion 2a1 of the upright wall 2a is wedge-shaped, and the top portion 2a'' is in line contact with the lower surface of the base formwork 1 located on the upper surface, so that the mixture and air bubbles can be discharged extremely smoothly. It's something to go on. When the base form 1 is completely placed on the base form 1, the hydraulic mixture such as gypsum and cement is in perfect tight pressure contact with the lower surface of the base form 1 located on the upper surface. In addition, if necessary, repeat this work in multiple stages toward the upper stage, and after pouring and curing, remove the base formwork 1 and peripheral formwork 2 located above in order.
By doing so, it is possible to obtain one or more desired architectural panels without the plastering and troweling process.

[Actions and effects of the present invention]

According to the present invention, when the base formwork 1 is gently placed on the upper surface of the hydraulic mixture 3 such as gypsum and cement that has been worked up to a slightly higher level, the pressure of the base formwork 1 causes the work to be worked out to a slightly higher level. The amount of hydraulic mixture 3 that has been removed gradually narrows the gap and escapes toward the gap between the upright wall 2a and top 2a'' of the base formwork 1 and peripheral formwork 2, but at this time, from the upper part Combined with the pressure of , the excess mixture and air bubbles are smoothly discharged from the gap between the upright wall portion 2a and the top portion 2a'' of the base formwork 1 and the peripheral formwork 2, which are in line contact without surface contact. The bottom surface of the base formwork 1 is completely connected to the standing wall part 2 of the peripheral formwork 2.
When it comes into contact with the top part 2a'', all excess mixture and air bubbles are discharged, and the upper surface of the hydraulic mixture 3 is in complete tight pressure contact with the lower surface of the base formwork 1, and after curing, when the formwork is removed, the plastering A smooth surface similar to that obtained by troweling will appear. Therefore, according to the present invention, it is possible to omit the plastering trowel finishing process, which requires skill and is inefficient in terms of labor and time when manufacturing a large number of panels. It has become possible to easily manufacture panels with smooth surfaces.

Furthermore, according to the method of the present invention, by final restraint, rapid restraint curing using steam or the like can be performed immediately after pouring, and it has also become possible to further improve manufacturing efficiency.
