And when this mineral fiber board 1 is used as a ceiling material, the mineral fiber board 1 has a width of 300 to 400 mm and a length of 1000 to 3000 mm.
After being formed into a size, the attachment is performed using the H bar 2 and the T bar 8. That is, as shown in FIG. 4, concave grooves 4 are provided on both longitudinal end faces of the mineral fiber board 1, and horizontal pieces 3 on the lower side of the H bar 2 are inserted into the concave grooves 4 to adjoin adjacent minerals. The fiber boards 1 are connected to each other, and the end portions of the mineral fiber boards 1 are placed on the horizontal pieces 9 of the T-bar 8 as shown in FIG.

た。However, in this structure, the load of the H bar 2 is received by the lower projecting piece 10 of the mineral fiber board 1 formed by the concave groove 4, and particularly in the portion mounted on the lateral piece 9 of the T bar 8. Since the weight of the mineral fiber board 1 and the load of the H bar 2 are added together, the shaded portion in FIG. 5 (usually 8.
5 × 10mm) is compressed and deformed, and the compression amount (h in Fig. 6 is
Is not constant depending on the amount of moisture absorbed by the mineral fiber board 1, but in the case of high humidity, it reaches about 1.0 to 1.5 mm, which greatly impairs the appearance. .

A thin protruding piece 10 is formed by providing a concave groove 4 on the side end portion of the mineral fiber board 1. The thin protruding piece 10 is warped and deformed as shown in FIG. There is also a problem in that the appearance may be greatly impaired due to the risk of being damaged.

得ることができるものである。First, the production of the mineral fiber board 1 for building materials according to the present invention will be described. As shown in FIG. 2, a wet mat 12 produced by papermaking a slurry containing mineral fibers such as rock wool and binder such as starch is mixed. The resin binder liquid 14 is applied to the upper surface side while being fed by the roll 13. Here, as the resin of the resin binder liquid 14, a thermosetting resin such as a polyacrylic amide-based resin or other melamine resin or phenol resin can be used. The resin binder liquid 14 is applied at a plurality of places, and the wet mat 12 is applied to the roll 13
As a result, the resin binder liquid 14 is applied in a plurality of strips. Further, a suction chamber 15 is provided on the lower surface side of the wet mat 12, and the resin binder liquid 14 is permeated and impregnated into the wet mat 12 by the suction force of the suction chamber 15. After the wet mat 12 is coated and impregnated with the resin binder liquid 14 as described above, the wet mat 12 is dried and cured, and the resin binder liquid 14 is added.
Can be dried and cured to obtain a wide plate 16 in which the resin 5 is impregnated in a band shape. The wide plate 16 is cut along the portion impregnated with the resin 5 as shown by the imaginary line in FIG.
It is possible to obtain the mineral fiber board 1 in which the concave portions 4 are provided on both side end faces over the entire length as shown in FIG.

るものである。In this mineral fiber board 1, the resin 5 is impregnated in the lower protrusions 10 formed by the concave grooves 4 provided at both ends. Therefore, the impregnated resin 5 reinforces the compressive strength of the lower part of the groove 4 of the mineral fiber board 1, and as shown in FIG. 4 and FIG. When installing the fiberboard 1 as a ceiling material or the like, by inserting the lower horizontal piece 3 of the H-bar 2 into the groove 4, the adjacent mineral fiberboards 1 are connected to each other and the mineral fiberboard 1 The end portion is placed on the horizontal piece 9 of the T-bar 8, and even if both the own weight of the mineral fiber board 1 and the load of the H-bar 2 are applied in the portion to be placed on the horizontal piece 9 of the T-bar 8, It is possible to prevent compressive deformation at this portion. When a thermosetting resin is used as the resin 5 to be impregnated, the hardening for preventing the compression deformation can be remarkably obtained. Further, the resin 5 is impregnated into the protrusions 10 on the lower side of the groove 4, so that the voids in the protrusions 10 are filled with the resin 5, so that the lower surface of the mineral fiber board 1 is coated with a coating material. Even if this is done, it is possible to prevent the coating material from penetrating into the inside of the protruding piece 10, and by suppressing the penetration of the coating material, the warp deformation of the protruding piece 10 can be suppressed to a small level.

ぞれ低減することができるものであった。By the way, in the conventional mineral fiber board 1 not impregnated with the resin 5, the compression deformation amount is 1.5 mm and the warp deformation amount is 0.1 to 0.
Although it is 2 mm, in the mineral fiber board 1 impregnated with polyacrylic amide as the resin 5 at a dry coating amount of 83 g / m · 1, the compression deformation amount is 0.8 mm and the warp deformation amount is 0.06. Can be reduced to ~ 0.08mm,
In addition, melamine resin is used as the resin 5 and 83 g / m · 1
In the mineral fiber board 1 impregnated with the dry coating amount of the book, the compression deformation amount could be reduced to 0.3 mm and the warp deformation amount could be reduced to 0 to 0.03 mm, respectively.

I formed a wide plate that was impregnated and cut it along the resin-impregnated part to create a mineral fiber board, so I cut the wide plate along the resin-impregnated part. By dividing, it is possible to prepare a large amount of mineral fiber boards impregnated with resin on the side end faces at one time, and it is not necessary to handle the mineral fiber boards one by one and impregnate them with resin. Moreover, since a horizontal groove of an H bar is inserted into the side end surface of the mineral fiber board to form a groove for connecting the adjacent mineral fiber boards, a groove is formed on the side surface of the resin-impregnated mineral fiber board. By doing so, even if the weight of the mineral fiber board and the load of the H bar are applied to the lower part of the groove, this part is reinforced by the impregnated resin,
It is possible to prevent compressive deformation, and moreover, the lower part of the groove is filled with voids by resin impregnation, and even if paint is applied by coating the lower surface of the mineral fiber board, Can be prevented from penetrating into this portion, and the warp deformation can be suppressed to a small level by suppressing the permeation of the paint.
