Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a construction board mounting structure for fixing wall panels and ceiling panels to a building frame. More specifically, the present invention relates to a structure for fixing a building board to a building frame via magnet pieces.

[Conventional technology]

Structures have already been developed in which building boards are fixed to building frames via magnetic pieces. For example, these techniques are disclosed in the following publications. ■ Japanese Unexamined Utility Model Publication No. 55-95754■ Publication of Utility Model Application No. 56-14134■ Publication of Japanese Utility Model Application No. 59-15669■ Publication of Japanese Utility Model Application No. 59-167144 In these publications, magnet pieces are attached to building boards or A structure is described in which the magnet is fixed to a sheet, a base material such as iron is fixed to a building frame, and the magnet pieces are attracted and fixed to the base material.

[Problem to be solved by the invention]

The structure in which architectural boards are fixed using magnetic pieces has the advantage of being easier and faster to fix, even by non-specialists, compared to structures in which they are fixed using adhesives, nails, screws, etc. There is. Furthermore, the construction board fixed at -1,
It has many advantages such as being easy to remove. However, this structure has the disadvantage that it is difficult to securely fix the architectural board compared to conventional adhesive structures or nailed structures. The reason for this is that the architectural board is fixed using the magnetic attraction force of the magnet pieces. By increasing the attraction force of the magnet pieces and increasing the number of magnet pieces used, the fixing force of the architectural board can be strengthened. However, in order to strengthen the magnet pieces, it is necessary to use a significantly more expensive material, such as a samarium cobalt magnet, which has the drawback of significantly increasing the construction cost per unit area. Furthermore, the use of strong magnetic pieces radiates strong magnetic fields into the room, which can affect the human body. The influence of magnetic fields on the human body has been proven through therapeutic devices that utilize magnetism. Furthermore, studies have begun on the physiological effects of magnetic fields on the human body. When a strong magnetic field is irradiated into a room from a magnet piece fixed to a building board, it has the negative effect of creating a strong magnetic field in the living space. For this reason, when it comes to a structure in which building boards are attracted and fixed using magnetic pieces, the most important factor is how weak the magnet can be used to securely fix the board. Therefore, this invention was developed for this purpose, and an important purpose of this invention is to provide a construction board mounting structure that can securely fix construction boards using weak magnets. be.

[Means to solve the problem]

The construction board 3 mounting structure of the present invention has the following configuration in order to achieve the above-mentioned object. (a) The magnet piece 1 is not directly fixed to the building board 3, but is attached to the building board 3 via the fixing member 2.
attached to the suction surface. (b) The magnet piece 1 has a protrusion 4, and the fixing member 2 has a recess 5 into which the protrusion 4 is fitted. (c) The first magnet piece is attached to the building board 3 via the protrusions 4 and the recesses 5. Therefore, the protrusions 4 of the magnet piece 1 protrude in a direction parallel to the surface of the building board 3. (d) The recess 5 of the fixing member 2 is provided at a position opposite to the projection 4 of the magnet piece 1 so that the projection 4 can be fitted therein. (e) The magnet piece 1 is attached to the building board 3 via the protrusion 4 that is fitted into the recess 5 of the fixing member 2. (f) Furthermore, the present invention is characterized in that play is provided between the protrusion 4 and the four parts 5, and the magnet piece 1 is attached to the construction boat 3 so that it can be moved to some extent with this gap.

[Effect]

The construction board 3 mounting structure of the present invention does not fix the magnet piece 1 to the construction board 3 as in the conventional case. The magnet piece 1 is movably fixed to a building board 3. In order to achieve this, the present invention attaches the magnet piece 1 to the building board 3 via the fixing member 2. The magnet piece 1 and the fixing member 2 are connected via a protrusion 4 and a recess 5. A play is provided between the protrusion 4 and the recess 5. The play is attached to the building board 3 so that the magnet piece 1 can be moved to some extent. In this state, the magnet piece 1 attached to the building board 3 can bring its attraction surface into close contact with the base material without any gaps. The magnet piece 1 in close contact with the base material is attracted to the base material with an extremely strong attraction force. Conventionally, since the magnet piece 1 was fixed to the building board 3, there was a drawback that the attraction surface of the magnet piece 1 could not be tightly attached to the surface of the magnet piece 1 without any gaps. If there is no misalignment between the building board 3 and the base material, and if it can be installed without error, then the magnet piece 1
can adhere to the base material. However, in actual construction, there is some misalignment in the architectural board 3 and the base material, which may impede the close contact between the magnet piece 1 and the base material. The reason why the magnetic attraction force decreases when the magnet piece 1 and the base material come into contact without being in close contact with each other is because the magnetic resistance of air is significantly higher than that of magnetic metal. As shown by the solid line in FIG. 1, when the magnet piece 1 is in close contact with the base material without any gaps, the lines of magnetic force coming out from the magnet piece 1 pass through the base material without passing through the air. However, as shown by the chain line in Figure 1, when the magnet piece 1 and the base material are inclined and make partial contact, most of the lines of magnetic force coming out of the magnet piece 1 pass through the base material after passing through the air. do. Magnetic field lines passing through the air are weakened by the air's high magnetic reluctance. For this reason,
If the magnet piece 1 and the base material cannot be brought into close contact with each other, the magnetic attraction force will be significantly reduced. The mounting structure of the construction boat 3 of this invention has the magnet piece 1
It is attached to the construction board 3 so that it can be moved somewhat. For this reason, the magnet piece 1 is pulled by the base material by magnetic attraction and is adsorbed in close contact with the surface of the base material. Therefore, the mounting structure of the architectural board 3 of the present invention is as follows:
Even if the construction board 3 or the base material is slightly distorted, and even if the first magnet piece is distorted in shape, the magnet piece 1 can be closely attached to the base material without any gaps and is attracted with strong force.

【Example】

Embodiments of the present invention will be described below based on the drawings. However, the embodiments shown below are illustrative of a structure for embodying the technical idea of this invention, and the structure of this invention is based on the following materials, shapes, structures, and arrangements of component parts. It is not specific. Various modifications may be made to the structure of this invention within the scope of the claims. Furthermore, in order to make the claims easier to understand, the numbers corresponding to the members shown in the embodiments are indicated in "Claims Column J" and "Means for Solving the Conventional Problems". Additional notes are added to the members shown in the "Column" and "Column of Action". However, the members shown in the claims are by no means limited to the members of the embodiments. In the construction board mounting structure shown in FIGS. 1 and 2, the construction board 3 is attached to the building frame 7 by the attraction force of the magnet piece 1. A base material 6 made of magnetic metal such as iron that can attract the magnet piece 1 is fixed to the building frame 7. The base material 6 is fixed in a grid pattern at regular intervals, as shown in FIG. The base material 6 shown in this figure extends in the horizontal direction and is fixed in parallel. The base material 6 is fixed to a concrete or wooden building frame 7 via anchor bolts or nails. The base material 6 is designed to have a width that can attract the entire attraction surface of the magnet piece 1. The magnet piece 1 is attached to a building board 3 via a fixing member 2. The magnet piece 1 shown in the figure is composed of a magnet body IA and a shield case IB. The magnet body IA is a permanent magnet such as a ferrite magnet. The magnet main body IA is formed into a cylindrical or prismatic shape. The magnet main body IA has a front end attraction surface and a rear end formed into a flat shape. The tip and rear ends are excited with different polarities. The shield case IB is attached to the base material 6,
A closed magnetic circuit is configured outside the magnet body IA. Therefore, the shield case IB is made of a magnetic metal such as iron that has low magnetic resistance. Further, the shield case IB is adsorbed to the base material 6 as shown in FIG. 1, and its tip is brought into close contact with the base material 6. Therefore, the leading edge of the shield case IB is designed to be flush with the attracting surface of the magnet body IA. When the shield case IB forms a closed magnetic circuit around the outer periphery of the magnet body IA, the shield case IB forms a closed magnetic circuit around the outer circumference of the magnet body IA.
Can shield the outside of. The magnetically shielded magnet body 1A can prevent lines of magnetic force from leaking to the outside. Therefore, it has the advantage that the magnetic field leaking to the outside of the building board 3 can be significantly weakened. Furthermore, since the magnetic circuit is closed with a metal having low magnetic resistance, the magnet piece 1 can be extremely strongly attracted to the base material 6. However, in this invention, it is not necessary to provide the shield case IB on the magnet piece 1. The magnet piece 1 is attached to the building board 3 so that it can move somewhat freely via the fixing member 2 without being fixed to the building board 3. In order to attach the magnet piece 1 to the building board 3, the shield case IB is provided with a protrusion 4 on the outer periphery of the bottom surface. The protrusions 4 are provided extending in a direction parallel to the surface of the building board 3 so that the magnet piece 1 can be attached to the building board 3 by hooking it onto the recess 5 of the fixing member 2. The magnet piece 1 shown in FIG. 4 is provided with protrusions 4 around the entire circumference of the shield case IB. The magnet piece 1 having this shape does not require specifying the orientation in which it is inserted into the fixing member 2, and can be conveniently used. The fixing member 2 has a recess 5 into which the protrusion 4 of the magnet piece 1 can be fitted. As shown in FIGS. 1 and 2, the recess 5 is provided corresponding to the protrusion 4 so that the protrusion 4 of the magnet piece 1 can be fitted and fixed therein. A gap is provided between the protrusion 4 and the recess 5 so that the magnet piece 1 can be moved to some extent when it is fitted into the fixing member 2. The gap is preferably adjusted to a range of 0.1 to several mm. The fixing member 2 shown in FIGS. 1 and 2 has a side wall made of elongated channel steel bent inward to provide a recess 5 inside the side wall. The fixing member 2 having this shape has a feature that the magnet pieces 1 can be freely moved and connected in the longitudinal direction. FIG. 3 shows a state in which the fixing member 2 is fixed to the building board 3. In the construction board 3 shown in this figure, the fixing members 2 are fixed in a vertically parallel grid pattern. Further, in FIG. 3, the base material 6 is horizontally extended and fixed to the building frame. As shown in this figure, when the base material 6 and the fixing member 2 are fixed in such a way that they cross each other vertically and horizontally, the intersection points can be attracted and connected by the magnet pieces 1. According to this structure, the base material 6 and the fixing member 2
construction board 3 without specifying the location to fix it.
It has the feature that it can be attached to the building frame 7. The building board 3 can be any board material that can be fixed to a wall or ceiling, or a frame covered with cloth or a surface finish sheet. Furthermore, FIG. 5 shows a specific example in which the fixing member 2 and the base material 6 have different cross-sectional shapes. The structure shown in this figure has the advantage that the heavy construction board 3 can be reliably connected to the building frame 7. In order to realize this, the fixing member 2 and the base material 6 are
The cross-sectional shape is L-shaped. The fixing member 2 is bent downward, and the base material 6 is bent upward. A magnet piece 1 is connected to a bent surface of a fixed member 2. The structure for connecting the magnet piece 1 to the fixed member 2 has the same shape as in FIG. 1. The magnet piece 1 is attracted to the upwardly bent surface. According to this structure, the fixing member 2 can be placed on the base material 6, and the weight of the building board 3 can be carried by the base material 6. Therefore, this structure is particularly suitable for heavy construction boards 3,
Alternatively, it can be effectively used on the ceiling.

【Effect of the invention】

The construction board mounting structure of the present invention has a feature that the construction board can be reliably attracted to the base material using a weak magnet piece. Therefore, it has the advantage that inexpensive magnet pieces can be used. In addition, even if there is a misalignment in the construction board, base material, or magnet piece, and even if there is some misalignment in the installation, the magnet piece should be tightly attached to the base material without any gaps, and the construction board should be fixed. It has the feature of being able to be fixed securely. Furthermore, after the building boards are installed, they can be adjusted in position. In addition, the magnetic pieces attached to the architectural board can be attracted and fixed to the base material without nailing or screwing, which greatly simplifies the construction work and allows even non-specialized engineers to perform the construction efficiently. . Therefore, the construction board mounting structure of the present invention has the advantage that it can be constructed easily, quickly, and efficiently. This, combined with the fact that the construction unit cost is reduced and inexpensive magnet pieces can be used, has the advantage that the cost per area can be significantly reduced. Furthermore, a noteworthy feature of the construction board mounting structure of the present invention is that the magnetic field irradiated indoors can be designed to be low, even though the construction board can be reliably attracted. This is because the building board can be reliably attracted to the building frame using a weak piece of magnet. As a result, the magnetic field in indoor living spaces can be weakened, making it possible to live with peace of mind. Furthermore, since the construction board mounting structure of the present invention allows the construction board to be easily replaced, it has the advantage of being able to accommodate a variety of designs to suit seasonal hobbies, tastes, celebrations and condolences, etc.
