Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a base material for attaching a building board material such as a gypsum board to a building body such as a wall or a ceiling.

[Conventional technology and its problems]

The method of pasting a board such as gypsum board on the wall surface of the building frame is cheap, and the wall surface can be beautifully finished.
It is often used in the structure of building walls. In this wall structure, an adhesive that is kneaded in a paste form is attached to the surface of the wall body in a dot shape, and the gypsum board is adhered through this adhesive. In the actual adhesive state, a highly viscous adhesive is adhered to the surface of the wall in a lump form, the gypsum board is pressed against this adhesive, the gap between the gypsum board and the wall is adjusted, and the surface of the wall is adjusted. The surface of the gypsum board is finished flat, regardless of the unevenness. However, in this construction method, the surface of the gypsum board cannot be finished to be a completely flat surface even though only a specific engineer constructs it. The reason is that the warped gypsum board cannot be straightened and fixed. When the gypsum board is transported to the site and laminated, it warps. In the field, it is practically impossible to store it without any warp. Further, the warped state changes depending on the stacked state. Gypsum board with warp cannot be fixed by fixing the warp with an adhesive. This is because the adhesive cannot fix the gypsum board in a partially pressed or pulled state. In the wall structure constructed in this state, it takes about 2 weeks to cure and dry the adhesive, and the construction period cannot be shortened. In addition, if a cloth or the like is attached to the surface in a state where the water content of the adhesive does not completely dry up to the central portion, the water content in the central portion migrates to the surface, causing mold. In addition, even if a cloth or the like is applied after the adhesive is completely dried, the adhesive absorbs moisture over time after the construction, and molds are likely to be generated on the wall surface depending on the climate and humidity. Molds that occur inside buildings have many problems in hygiene, and in particular, they are social problems such as affecting childhood asthma. From this, the molds that make up the living space are
You have to get rid of everything. In the wall of this structure, the board is pressed against the wall surface with the adhesive being uncured to finely adjust the mounting position, and the entire wall surface is finished to be flat. Therefore, fixing the board requires a very high level of skill and requires a specialized technician to work carefully. The reason why it is difficult to construct the board is that it cannot be pulled back again. Further, since many points of the board are fixed to the building frame through a large amount of adhesive, it is very difficult to replace the board for repairing damage or changing the pattern. However, damage to the board during construction and use after completion is unavoidable. Damaged boards should be crushed into small pieces by hitting the surface. A number of hardened adhesives are ground and removed. This work pollutes the surroundings and is extremely labor intensive. A frame fixing bar is fixed on the surface of the building frame, and panel fixing bars are connected at regular intervals perpendicular to the frame fixing bar,
The base material of the building board material which fixes the board to the panel fixing bar by screwing has been developed. The base material having this structure can eliminate the harmful effects of moisture. The base material of this structure is superior to the above-described structure using an adhesive in most points except the unit price for construction. However, almost no base material is used for the walls of the actually constructed building, and a construction method using an adhesive is adopted. No matter how excellent the features are, they cannot be used for anything other than special purposes unless the unit price can be reduced. Since the adhesive method cannot be used for the ceiling, a base material that is suspended from the body is used. However, the conventional base material requires a technique for fixing the panel fixing bar to the body fixing bar, and also requires a high technique for horizontally aligning and fixing the body fixing bar. For this reason, in the conventional construction method, only a first-class or second-class expert engineer is actually performing the construction. By the way, as a base material for fixing the building board to the building frame, the structure fixing bars are fixed to the building structure at regular intervals, and the panel fixing bars are connected at regular intervals so as to intersect the frame fixing bars at right angles. Has been developed (Japanese Patent Publication No. 47-42)
70 publication). The base material described in this publication connects the frame fixing bar 2 and the panel fixing bar 3 with a clip 4, as shown in FIG. This figure is a perspective view of the body fixing bar fixed to the building body, as viewed from the back side. In this figure, the skeleton fixing bar is fixed to the building skeleton, and the building board is fixed to the panel fixing bar. The clip in this figure is
It is attached to the back surface of the panel fixing bar 3, and the frame fixing bar 2 which is an angle is sandwiched by the hook claw pieces 4D. In order to attach the clip 4 to the back surface of the panel fixing bar, the panel fixing bar is bent in a U shape so that the central portion thereof projects to the back surface.

[Problems to be solved by the device]

As shown in FIG. 7, the base material for connecting the panel fixing bar to the body fixing bar via the clip can connect the panel fixing bar to the body fixing bar without using an adhesive material or a screw. However, the base material of this structure is
Since it is sandwiched between the back surface of the panel fixing bar and the body fixing bar, it is not easy to install and the panel fixing bar cannot be efficiently connected to the body fixing bar. This is because the clip is attached to the back surface of the panel fixing bar. Further, pushing down the clip mounted on the back surface of the panel fixing bar to lock and connect the hook claw piece to the body fixing bar also hinders efficient connection. In particular, it is difficult to firmly attach the clip to the panel fixing bar in order to push down the clip with ease on the back side of the panel fixing bar that cannot be easily worked. This is because if the clip is firmly attached to the panel fixing bar, it cannot be pushed down easily. Further, since the clip is slid downward to lock the hook claw piece on the body fixing bar, the hook claw piece also needs to be shaped so that the body fixing bar can be inserted without difficulty. This makes it difficult to firmly attach the clip to the panel fixing bar, and also to firmly connect the hook claw piece to the body fixing bar. The clip, which is difficult to have a structure that is firmly connected, is likely to have a play between the panel fixing bar and the body fixing bar in the connected state. If play is possible during this period, there is also a drawback that the fixed building board material vibrates and rattles, and noise is easily generated. The base material of this invention was developed for the purpose of further solving this drawback, and the important purpose of this invention is to eliminate the drawbacks of the adhesive construction method, and to specialize in the experience and skill of the builder. There is no limitation, and it is to provide a base material that can easily increase or decrease the number of construction workers. Another important object of the present invention is to provide a base material for a building board that can be remarkably reduced in construction unit price because of its simple construction and high work efficiency. Another important purpose of this invention is not to bond the board with a large amount of adhesive, but to minimize the mold generated on the surface of the board due to the adhesive, and to cure the adhesive. There is no need for a waiting period, the construction period can be shortened, and anyone can easily and easily fix the structure of the wall of the building quickly.

[Means for solving the problem]

In order to achieve the above-mentioned object, the base material to which the building board material of the present invention is attached has the following constitution. The base material of the present invention comprises a frame fixing bar 2 fixed in parallel to a building frame 1 such as a wall surface or a ceiling at a predetermined interval, and a panel fixing bar 3 crossing and connected to the frame fixing bar 2. A clip 4 for connecting the panel fixing bar 3 to the frame fixing bar 2 is provided, and the construction plate material K is attached to the panel fixing bar 3. Furthermore, the base material of this invention is provided with a fixed convex portion 3C projecting toward the building plate material K at the center of the panel fixing bar 3, and further, both sides of the fixed convex portion 3C are fixed to the building plate material. The connecting portion 3A is formed by bending it in a step shape away from K. On the other hand, the clip 4 for connecting the panel fixing bar 3 to the frame fixing bar 2 includes a clip piece 2A for elastically sandwiching the frame fixing bar 2 and connecting itself to the frame fixing bar 2, and a panel fixing bar 3 And a pressing portion 4B for pressing and connecting the connecting portion 3A to the body fixing bar 2. The panel fixing bar 3 is set on the body fixing bar 2, the clip 4 is attached to the body fixing bar 2 from the front of the panel fixing bar 3, and the panel fixing bar 3 is connected to the body fixing bar 2. It has a unique structure.

[Action]

The base material of this invention is used in the following conditions. As shown in FIG. 1, the skeleton fixing bars 2 are fixed to the surface of the building skeleton 1 at predetermined intervals. The skeleton fixing bar 2 is directly fixed to the building skeleton 1 by adhesion, nailing, screwing, or a combination thereof. The frame fixing bar 2 does not specify the fixing position of the building board K. In other words, the skeleton fixing bar 2 does not need to be fixed in accordance with the fixing position of the building board K. The panel fixing bar 3 is located at the boundary position of the building board.
It is specified by the fixed position of. The skeleton fixing bar 2 is for attaching the panel fixing bar 3 to the building skeleton 1, so that it is sufficient that the panel fixing bar 3 can be fixed. Even if the attachment intervals of the frame fixing bars 2 are somewhat uneven, the panel fixing bars 3 can be fixed in place as long as they are fixed substantially in parallel. This is because the panel fixing bar 3 is connected to the frame fixing bar 2 with the clip 4 by adjusting the distance between the panel fixing bars 3. Since it is not necessary to specify the mounting position of the frame fixing bar 2, the frame fixing bar 2 can be easily fixed to the building frame 1. As shown in FIG. 2, one row of panel fixing bars 3 is connected to the frame fixing bar 2. The panel fixing bar 3 is connected to the body fixing bar 2 via a clip 4. Clip 4 is
The panel fixing bar 3 is pressed and connected to the frame fixing bar 2. The panel fixing bar 3 is fixed at a fixed interval according to the fixing position of the building board K. In order to connect the frame fixing bar 2 to the frame fixing bar 2 at a constant interval, the frame fixing bar 2 is marked at a constant interval and the panel fixing bar 3 is connected to the frame fixing bar 2 based on this mark. The panel fixing bars 3 can be easily attached to the body fixing bars 2 at regular intervals.
In order to fix the panel fixing bar 3, the clip 4 which can adjust the interval between the panel fixing bars 3 can be used to fix the upper and lower parts of the panel fixing bar 3. Clip 4 that can be used for this purpose
Is shown by a chain line in FIG. Clip 4 of this structure
Can be pushed from the top to the bottom to connect the panel fixing bar 3 to the body fixing bar 2. Therefore, by adjusting the total length of the clip 4 to the panel fixing bar interval, the panel fixing bar 3 can be connected to the frame fixing bar 2 at a constant interval. For the base material, it is necessary to fix the panel fixing bars 3 at regular intervals according to the size of the building board material stretched on the surface.
This is because the building board is fixed to the panel fixing bar 3 at a predetermined position. That is, since the building board is fixed to the panel fixing bar 3 on both sides and in between, for example, in 3 to 6 rows, the panel fixing bar 3 must be fixed at intervals that evenly divide the width of the building board. If the fixing position of the panel fixing bar 3 is deviated, the building board cannot be accurately fixed to the panel fixing bar 3 even if a fixed position is nailed. If the clip 4 for attaching the panel fixing bar 3 is used together with the jig for dimensioning the panel fixing bar 3,
Then, by fixing the panel fixing bar 3, the panel fixing bar 3 can be attached at a precisely determined position, and the panel fixing bar 3 can be attached extremely easily and easily.
Moreover, there is a feature that anyone can do it quickly without requiring technology. The panel fixing bar 3 whose upper and lower ends are fixed by the clip 4 which can be fixed by adjusting the interval is connected to the body fixing bar 2 by the clip 4 shown by the solid line in FIG.
As shown in FIG. 3, the panel fixing bar 3 is connected to the skeleton fixing bar 2. The building board K is fixed to the surface of the panel fixing bar 3. The building plate material K is directly fixed to the panel fixing bar 3 via a tapping screw, or is fixed to the panel fixing bar 3 via a fixture. This invention does not specify the structure for connecting the building board K to the panel fixing bar 3. 4 and 5 show a specific example of fixing the building board K to the panel fixing bar 3. The building board K of FIG. 4 is fixed to the panel fixing bar 3 via tapping screws. The building board K of FIG. 5 is fixed to the panel fixing bar 3 via a fixture. The base material of this invention can fix the building board material K more easily by performing the following steps regardless of the above steps (1) to (3). In the construction methods (1) to (3), after fixing the frame fixing bar 2 directly to the building frame 1, the panel fixing bar 3 is connected. Unlike the above method, if the skeleton fixing bar 2 is temporarily fixed to the building skeleton 1 via the fixing bar and the panel fixing bar 3, the construction can be performed more easily. In this case, the construction is performed in the next step. Fix the fixing bar to the ceiling and floor. The fixing bar is fixed parallel to the wall. The fixing position of the fixing bar determines the fixing position of the panel fixing bar 3. The farther the fixing bar is fixed from the wall, the wider the distance between the panel fixing bar 3 and the wall becomes. On the contrary, when the fixing bar is fixed close to the wall, the gap between the panel fixing bar 3 and the wall is narrowed. The fixed position of the fixed bar is determined when the position of the panel fixed bar 3 is determined. When the skeleton fixing bar 2 is adhered to the surface of the wall, the mounting position of the fixing bar is determined so that the back surface of the skeleton fixing bar 2 contacts the surface of the wall. It is preferable that the fixing bar is provided with a protrusion (not shown) indicating the fixing position of the panel fixing bar 3, or a mark of the fixing position. In this way, the fixing bar whose connection position of the panel fixing bar 3 can be specified uses all the clips 4 having the structure shown by the solid line in FIG.
Can be easily and accurately connected to the body fixing bar 2. Therefore, in this case, it is not necessary to use the clip 4 for adjusting the interval between the panel fixing bars 3. The frame fixing bar 2 can also be fixed to a wall via a spacer. In this case, the frame fixing bar 2 is fixed at a position slightly separated from the wall surface. When fixing the building board K to the building body 1 via the panel fixing bar 3, the body fixing bar 2 and the fixing bar, the distance between the fixing bar and the wall determines the distance between the building board K and the wall. To do. Therefore, the fixed bar is determined by the distance between the building board K and the building frame 1 determined. The state in which the fixing bar connects the panel fixing bars 3 is shown in FIG. The end portion of the panel fixing bar 3 is inserted and connected to the fixing bar 7. The fixing bar 7 is formed in a groove shape with an elastic plate such as a metal plate. The fixing bar 7 is fixed to the floor with anchor bolts or the like. The interval between the groove-shaped fixing bars 7 is adjusted to the thickness of the panel fixing bar 3. Both ends of the panel fixing bar 3 are inserted and connected to the fixing bar 7 fixed to the building body 1. The panel fixing bar 3 and the fixing bar 7 can be connected by another connecting member. The fixed bar fixed to the ceiling has the same structure as the floor, and the upper end of the panel fixed bar 3 is connected to the fixed bar. The frame fixing bar 2 is connected to the panel fixing bar 3 connected to the fixing bar 7. In this state, the frame fixing bar 2 is fixed at a fixed position. The body fixing bar 2 is fixed to the wall. The body fixing bar 2 and the wall are fixed by filling the gap between them with an adhesive, or inserting a spacer between them to bond them, or fixing the body fixing bar 2 to the wall with a nail. Then, the building plate material K is fixed to the surface of the panel fixing bar 3. The base material fixed by this method has a feature that the skeleton fixing bar 2 can be simply and easily fixed to the building skeleton 1 accurately.

[Preferred embodiment]

An embodiment of the present invention will be described below with reference to the drawings. However, the examples shown below exemplify a base material for embodying the technical idea of the present invention, and the base material of the present invention has the following components, materials, shapes, structures, and arrangements. Not specific to structure. The base material of this invention is subject to various modifications within the scope of the claims for utility model registration. Further, in this specification, in order to facilitate understanding of the scope of claims for utility model registration, the numbers corresponding to the members shown in the embodiment are
It is added to the members shown in "Column for request for utility model registration", "Column for means for solving conventional problems", and "Column for action and effect". However, the members shown in the scope of claims for utility model registration are by no means limited to the members of the embodiment. The base material for fixing the building plate material K shown in FIG. 4 to the building frame 1 is a frame fixing bar 2 fixed to the building frame 1 and a panel fixing bar 3 for connecting the building plate material K and fixing the building plate material K. And a clip 4 for connecting the panel fixing bar 3 and the body fixing bar 2. The body fixing bar 2, the panel fixing bar 3 and the clip 4 are
Manufactured from metal or synthetic resin. The frame fixing bar 2 has a groove in the center and both sides are bent downward in a V shape. The fixing portion 2A located at the groove bottom of the frame fixing bar 2 is fixed to the wall surface of the building frame 1. When the fixing part of the frame fixing bar 2 is bonded to the building frame 1,
A plurality of through holes can be bored here to firmly fix them. When the skeleton fixing bar 2 is nailed or screwed to the building skeleton 1, a stop hole (not shown) is previously drilled through the back surface of the skeleton fixing bar 2. The panel fixing bar 3 has a connecting portion 3A connected to the body fixing bar 2 with a clip 4. The panel fixing bar 3 in FIG. 4 has connecting portions 3A on both sides. The panel fixing bar 3 having the connecting portions 3A on both sides has a feature that both sides can be surely connected to the frame fixing bar 2 by the clip 4. As shown in FIG. 4, the panel fixing bar 3 is provided with a fixing convex portion 3C projecting toward the building plate K at the center.
Further, in the panel fixing bar 3, both side portions of the fixing convex portion 3C are bent to form a connecting portion 3A. The connecting portion 3A is bent in steps so as to be separated from the fixed building board K. The panel fixing bar 3 shown in FIG. 4 with the center portion highly bent.
When the tapping screw is screwed into the fixing convex portion 3C to fix the building board K, the tip of the screw can be in a state of not hitting the frame fixing bar 2. Therefore, the panel fixing bar 3 is not restricted by the screwing position of the tapping screw. In addition, the bent panel fixing bar 3 has an effect of increasing bending strength by using a thin metal plate. Panel fixing bar 3 that fixes the building board K by screwing in tapping screws
It is also possible to arrange a large number of notches 6 in a vertical arrangement. The notch 6 is provided extending laterally. The clip 4 is shown in FIG. This clip 4
The upper and lower sides are bent in the same direction and the cross section is U-shaped. A sandwiching piece 4A is provided on each of the bent sides. The sandwiching pieces 4A thus sandwich the both sides of the body fixing bar 2. Therefore, the inner space between the two sandwiching pieces 4A is made substantially equal to the width of the body fixing bar 2. The sandwiching piece 4A is elastically deformed to sandwich the body fixing bar 2. Therefore, the clip 4 is entirely made of a material that can be elastically deformed, such as a metal plate or a hard synthetic resin. As the metal plate, a normal metal plate may be used to have elasticity so that the sandwiching piece 4A sandwiches the body fixing bar 2. Therefore, the clip 4 does not necessarily have to be manufactured from a spring material. The sandwiching piece 4A is elastically deformed to sandwich the body fixing bar 2.
In other words, when the clip 4 is connected to the body fixing bar 2, the sandwiching piece 4A elastically sandwiches the body fixing bar 2. Therefore, in the state where the clip 4 is removed from the body fixing bar 2, the inner space of the sandwiching pieces 4A is manufactured to be slightly narrower than the width of the body fixing bar 2 to be precise. However, if the inner space of the sandwiching pieces 4A is too narrower than the width of the body fixing bar 2, it cannot be easily fixed to the body fixing bar 2. Therefore, even if the inner spacing of the sandwiching pieces 4A is narrow, the sandwiching pieces 4A are manufactured so as to be several mm narrower than the width of the body fixing bar 2. The sandwiching piece 4A of the clip 4 shown in FIG. 4 (A) projects inward and is bent in a "dogleg" shape so that it can be more accurately connected to the body fixing bar 2. The sandwiching piece 4A of this shape is
As shown in FIG. 4 (C), the bent portion is the frame fixing bar 2
It can be fixed in a state where it does not come off easily as it protrudes inward. Further, the sandwiching piece 4A does not necessarily need to extend to the tip of the pressing portion 4B as shown in FIG. 4 (A), and can be shortened as shown in FIG. 4 (B). . At the tip of the clip 4, a pressing portion 4B that presses and connects the panel fixing bar 3 to the body fixing bar 2 is provided.
The clip 4 shown in FIG. 4 presses the connecting portion of the panel fixing bar 3 against the body fixing bar 2. The pressing portion 4B of the clip 4 shown in FIG. 4 (A) is provided with a small projection 4C at the tip portion of the pressing surface in order to securely fix the panel fixing bar 3 in the pressed state. On the other hand, the connecting portion 3A of the panel fixing bar 3 is provided with ridges 3B along both side edges. The panel fixing bar 3 manufactured by bending a metal plate can have both end edges folded back and a ridge 3B can be provided on the end edge. In the clip 4 having this structure, when the pressing portion 4B is slid toward the panel fixing bar 3 as shown by the arrow in FIG. 4 (D), the small protrusion 4C of the pressing portion 4B causes the protruding portion 3B of the connecting portion to move. Over. In this state, the small protrusion 4C of the pressing portion 4B is in a state of being caught by the connecting portion 3A of the panel fixing bar 3, and the clip 4 is prevented from coming out. FIG. 4 shows a base material for fixing the building board K to the wall. With the same structure, the building board K can be fixed to the ceiling. Therefore, this invention does not specify the use of the base material to the wall. FIG. 5 shows a state in which a building board K, which is a ceiling board, is fixed with a base material. The same structure as that shown in FIG. 4 can be used for the structure for fixing the panel fixing bar to the ceiling body with this base material. The panel fixing bar uses channels having an E-shaped cross section. This is to prevent nail heads or the like from appearing on the surface of the building board material K, which is a ceiling board with a decorative surface. The panel fixing bar 3 is connected to the body fixing bar 2 in the same structure as that shown in FIG. A clamp 8 is attached to the panel fixing bar 3.
The ceiling board is connected via. On the top surface of the ceiling board,
The metal fitting 9 is fixed along the edge. The metal fitting 9 is an end-shaped clamp 8 shown in FIG.
And is connected to the panel fixing bar 3. The clamp 8 is
As shown in FIG. 5, itself is sandwiched between the metal fittings, and the lower end of the panel fixing bar 3 is pressed against the metal fittings by the projecting piece at the end to connect the metal fittings. The clamp 8 may have the same shape as the clip 4 shown by the chain line in FIG. The insert plate 10 is fixed to the other end of the ceiling plate whose one side is connected to the panel fixing bar 3 by the bracket 9. Insert metal fitting 10
Is pushed into the bracket 9 of the adjacent ceiling plate and connected to the panel fixing bar 3. That is, the insert fitting 10 is pushed between the bracket 9 and the ceiling plate. One end edge of the ceiling plate is a metal fitting 9, and the other end edge is connected to the panel fixing bar 3 via an insertion fitting 10. In addition to being easy to install, the ceiling board of this structure is
Since the heads of nails and screws do not appear on the surface of the ceiling plate, it is ideal for attaching a surface finish plate. In FIG. 5, a ceiling board is used as the building board K. It is also possible to fix a wall board which is a surface decorative finish board by using a base material having the same structure as this.

[Effect of device]

The base material of the present invention has a feature that it can be applied easily and quickly as compared with the conventional base material structure and the structure using the adhesive. The reason is that the clip can easily and quickly connect the panel fixing bar to the body fixing bar. Particularly, in the base material of the present invention, the panel fixing bar and the body fixing bar can be connected by mounting the clip from the front surface of the panel fixing bar with the panel fixing bar along the body fixing bar. This is because a stepped connecting portion is provided on both sides of the panel fixing bar, and the connecting portion is pressed against the body fixing bar by the pressing portion of the clip to be connected.
