Whereby the reinforcement can be done simply easily and securely.

Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to a reinforcing device for a building board, and more specifically, the present invention relates to a reinforcing device for a building board.
This relates to technology that aims to simply and easily reinforce the fitting recess and the nailing piece. [Jubei's Reinforcement Technique 1 For example, in order to reinforce the protrusions, fitting recesses, and nailing pieces of a building board such as inorganic fiberboard, a reinforcing material 5 was applied as shown in Fig. 3. The reinforcing material 5 is applied by rotating the disc 9 in contact with the back surface of the convex part 2 and the surface of the nailing piece 4. [Problem to be solved by the invention] However, due to the contact rotation by the disk 9, the reinforcing material 5
For those that apply reinforcing material 5 depending on the degree of contact.
If the application amount is changed and the contact pressure is too strong,
There is a risk of breaking the convex part 2 and the nailing piece 4, and there is also the problem that it is difficult to apply the reinforcing material 5 to the inner part of the four fitting parts 3, making it difficult to provide sufficient reinforcement. The present invention was made in view of such problems,
The purpose of this is to be able to easily supply reinforcing material not only to the convex part and the recessed piece, but also to the deep part of the fitting gate, and to perform reinforcement sufficiently and easily. Our goal is to provide a building board reinforcement device that can.

[Means for Solving the Problems] The building board reinforcing device of the present invention has a convex part 2 formed at one gA end of the building board main body 1, and a fitting in which the convex part 2 can be fitted to the other end. This is a building board reinforcing device in which a fitting part 3 is formed and a nailing piece 4 is extended to the back side of the building board main body 1 on the side of the fitting recess 3, and a reinforcing material 5 is provided on the back side of the convex part 2. A second nozzle 7 that sprays the reinforcing material 5 into the fitting recess 3, and a third nozzle 8 that sprays the reinforcing material 5 onto the surface side of the nailing piece 4. It is characterized by:

[Function] In this way, the first nozzle 6 sprays the reinforcing material 5 on the back side of the convex part 2, the second nozzle 7 sprays the reinforcing material 5 inside the fitting recess 3, and the second nozzle 7 sprays the reinforcing material 5 on the back surface side of the nailing piece 4. By having a third nozzle 8 for spraying the reinforcing material 5 on the convex portion 2, the fitting recess 3, and the nailing piece 4, the first nozzle 6 is provided, respectively.
, the reinforcing material 5 is sprayed using the second nozzle 7 and the third nozzle 8, so that the convex part 2 and the nailing piece 4 are not accidentally damaged, and the reinforcing material 5 is sprayed to the inner part of the fitting recess 3. A sufficient amount of reinforcing material 5 is supplied so that reinforcing can be performed easily and reliably.

[Example] Embodiments of the present invention will be described in detail below based on the drawings.

The building board A is made of, for example, inorganic fiberboard, which is made by making a slurry, drying it, and cutting it into a fixed size, and is constructed as, for example, a ceiling board. A convex portion 2 is formed on one side light on the long side of a building board A formed in a square shape. A fitting gate 3 into which the convex portion 2 can be fitted is formed at the other end. A nailing piece 4 is extended on the back side of the building board main body 1 on the side of the fitting recess 3. Such a building board body 1 is turned over, loaded on a conveyor, and transported.
In the middle of the conveyor path, there are a first nozzle 6 that sprays the reinforcing material 5 on the back side of the convex part 2, a second nozzle 7 that sprays the reinforcing material 5 into the fitting recess 3, and a surface of the nailing piece 4. A reinforcing device is provided with a third nozzle 8 for spraying reinforcing material 5 on the side.

In this way, the first nozzle 6 sprays the reinforcing material 5 onto the back side of the convex part 2, the second nozzle 7 sprays the reinforcing material 5 into the fitting recess 3, and the reinforcing material 5 sprays onto the front side of the nailing piece 4. 5, the convex portion 2 and the fitting recess 3 are
The reinforcing material 5 is sprayed onto the nailing piece 4 using the first nozzle 6, the second nozzle 7, and the third nozzle 8, respectively, so that the convex part 2 and the nailing piece 4 may be accidentally damaged. Without,
The reinforcing material 5 is sufficiently supplied to the deep part of the fitting recess 3,
Reinforcement can be easily and reliably performed.

FIG. 2 shows the cross-sectional shape of the second nozzle 7, which is formed into a double tube shape and has a central tube section 10 to which the reinforcing material 5 is supplied, and a section between the central tube section 10 and the outer tube section 11. Pressure air is supplied and discharged to the annular passage 12, and the reinforcement material 5 is blown out from the central pipe portion 10 by suction action by the discharge of the pressure air, and a minute amount of reinforcement material 5 of, for example, 4g per 1×2 scale is blown out.
can be applied evenly and thinly.

The reinforcing material 5 that is blown out is a solvent type acrylic paint, but it goes without saying that other materials may also be used.

[Effects of the Invention] In summary, the present invention has a first nozzle that sprays a reinforcing material on the back side of the convex part, a second nozzle that sprays the reinforcing material inside the fitting recess, and a reinforcing material on the front side of the nailing piece. Since the reinforcing material is sprayed on the convex part, the fitting recess, and the nailing piece using the first nozzle, the second nozzle, and the third nozzle, respectively, There is an advantage that there is no accidental damage to the real part and the nailing piece, that a sufficient amount of reinforcing material can be supplied even to the deep part of the fitting recess, and that reinforcing can be performed easily and reliably.
