Field of the Invention The present invention relates to a joint structure between inner wall panels in which no step is formed between juxtaposed inner wall panels. 2. Description of the Related Art As a method of constructing an inner wall of a building such as a house, a panel having a required shape and dimensions is manufactured in advance by a dedicated tool at a member manufacturing factory, and the panel is transferred to a construction site. At the construction site, the top and bottom of the panel are
There is a method of fixing only to the floor and fixing between adjacent panels. According to this construction method, when constructing the inner wall, the on-site worker does not need specialized knowledge and skill such as processing and dimensional accuracy determination, and since it is manufactured as a panel with a dedicated jig at a factory, high accuracy is achieved. Things can be constructed. [0003] By the way, it is indispensable to fix the adjacent panels between the adjacent panels when constructing the inner wall on site. If the fixing between the adjacent panels is not performed, when a load is applied in the plane direction of the panel, the upper and lower sides of the panel are fixed to the ceiling and the floor and do not move, but when the panel is bent at the center in the height direction. A step occurs between adjacent panels. In particular, when a separate load is applied in the plane direction to each adjacent panel while a decorative sheet such as a cloth is stretched on the panel surface, the bending between the panels is slightly different, and a step is generated between the panels. For a long period of time, the decorative sheet breaks at the seam of the panel. Conventionally, a wood material has been used for the frame material of the panel because of its ease of processing, weight, strength, and the like.
The fixing between the panels is performed by fixing the adjacent vertical frame members with an adhesive or a nail. But,
Unless production control and the like are sufficient for a panel using a wooden frame material, there is a possibility that warpage or twisting may occur due to a change over time or a change in humidity. In order to solve the problem caused by the wooden frame material, it is conceivable to use a steel plate frame material as the panel frame material. This steel sheet frame is formed by bending a thin steel sheet into a lip groove shape or a square tube shape, and has the advantage of being lightweight and having high rigidity without warping or twisting due to aging or humidity change. However, in the case of the panel using the above-mentioned steel sheet frame material, the panels must be fixed to each other by rivets, welding, adhesives or the like instead of nails, and workability problems and safety related to the fixing are required. There was a problem that lacked reliability and reliability. That is, in the case of using rivets, the work is not only large and complicated, but also there is a problem that the work cannot be performed from the side where the face material is adhered when the outer wall is installed on the indoor side. Is a combustible material, so there is a risk of fire during welding. In the case of using an adhesive, the adhesive is difficult to adapt to the steel sheet frame material, and there is a problem in the reliability of adhesion. SUMMARY OF THE INVENTION [0007] The present invention has been made in view of the above points, and has been made in consideration of the above-described problems. Therefore, it is possible to easily and reliably fix the inner wall panels having a steel frame member. It provides a seam structure. [0008] That is, the present invention provides:
In the inner wall panel made of a steel plate for the vertical frame material, a vertically long concave portion is provided on the outer surface of the vertical frame material to be a joining surface between the inner wall panels, and a space between the concave portions formed when the panels are joined is substantially the same as the concave space. The present invention relates to a joint structure between inner wall panels, wherein an elastic fixing member having a matching cross-sectional shape is provided. The present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a perspective view showing a joint structure between inner wall panels according to an embodiment of the present invention, and FIG.
FIG. 3 is a partial sectional view showing another example of the joint structure. The inner wall panel 10 shown in FIG.
1 and a panel material 15 stretched on both sides of the panel frame 11 and attached as a partition wall or the like to the ceiling and floor of a building such as a house. In this embodiment, the width is 910 m.
m, a height of 2385 mm, and a thickness of the panel frame 11 of 50 mm. A face material 15 made of a gypsum board having a thickness of 12.5 mm is stretched on both sides of the panel frame 11. The panel frame 11 includes vertical frame members 21 and 21, horizontal frame members 31 and 31, and a vertical frame member 21 between the vertical frame members 21 and 21.
And a vertical core member 25 arranged in parallel. The vertical frame member 21 and the vertical core member 25 are made of a thin steel plate shaped steel that does not warp or twist due to a change over time or a change in humidity. Thin steel sheet is a steel sheet that has been subjected to anticorrosion treatment such as galvanization.When used for interior wall panels for houses,
A plate having a thickness of about 0.5 to 0.9 mm is preferable from the viewpoint of strength and workability. The cross-sectional shape of the vertical frame member 21 and the vertical core member 25 is selected from the groove shape or the square tube shape in addition to the lip groove shape as in the embodiment, in consideration of strength and workability. It is appropriately selected, and the external dimensions are determined in consideration of the wall thickness and the thickness of the face material 15. Further, in the vertical frame member 21, a concave portion 23 which is continuous in the vertical direction is formed in the inter-panel joint surface 22 of the inner wall panel 10. The concave portion 23 is a portion where the elastic fixing material 41 to be described later is arranged and fitted, and has a cross-sectional shape that facilitates the forming process of the vertical frame member 21 and the elastic fixing material 41 and that the panel 10 is joined when the panels 10 are joined to each other. It is preferable that the shape is such that the elastic fixing member 41 and the elastic fixing member 41 can be easily fitted.
For example, a concave portion 23 of the vertical frame member 21 shown in FIG. 2 is formed in a semicircular shape to form a space 24 having a circular cross section at the time of joining, or a concave portion 63 of the vertical frame member 61 in the panel 50 shown in FIG. It has an appropriate concave shape, such as a V-shaped one that forms a space 64 with a rhombic cross section at the time of joining, or a space that has an oval or square cross section at the time of joining. In each drawing, reference numerals 10A and 50A are adjacent panels. Also, in FIG.
Is another example of the elastic fixing member, and the same reference numerals as those in the above-described embodiment denote the same members. In order to facilitate the attachment of the inner wall panel 10 to the ceiling and floor surfaces and to facilitate the production of the panels, the horizontal frame member 31 is made of a plywood thin plate. The frame members 21 and 21 and the vertical core member 25 are fitted and fixed in fitting grooves 26, 26 and 27 formed by cutting out upper and lower portions. The horizontal frame member 31 is fixed to receiving members (not shown) provided on the ceiling surface and the floor surface in advance.
It is provided so as to protrude a predetermined amount above and below the face member 15 or the like to be attached. As the face material 15, an appropriate material such as a gypsum board or a plywood is selected, and attached to at least one surface of the panel frame 11 with a connecting member P such as an air pin or a tex screw. The elastic fixing member 41 is disposed in the concave portion 23 of the vertical frame member 21 which serves as a joint surface when the panels 10 are joined, and fixes the panels 10 to each other. The elastic fixing member 41 has a cross-sectional shape substantially matching the space 24 formed between the concave portions 23 when the panel 10 is joined,
The inner wall panel 10 is made of a material having a strength that can be easily fitted into the concave portion 23 when the panel 10 is joined, is durable, and is not easily deformed by a shear force in the surface direction of the inner wall panel 10. Examples of the material thereof include a metal having a spring elasticity (for example, a metal pipe having a slit-shaped notch formed on a side surface thereof) in addition to a material made of a semi-hard vinyl chloride resin, a synthetic rubber, or the like. The elastic fixing member 41 of the embodiment shown in FIG. 2 is made of a semi-rigid vinyl chloride resin having a columnar shape with a diameter of about 10 mm. Also, this elastic fixing material 41
In addition to providing an appropriate length at the center of the vertical frame member 21 of the panel 10 in the height direction of the panel 10 where bending and a step are likely to occur, the panel may be provided in the concave portion 23 over the entire length of the vertical frame member 21. Next, a description will be given of a construction method in which the inner wall panels 10 having the above-described structure are juxtaposed as partition walls of a building.
First, before or immediately before, the elastic fixing material 41 is attached to the concave portion 23 of the vertical frame member 21 which is the joining surface of the panel 10 on one side with a normal adhesive or a rapidly curable adhesive, and the panel 10 is attached. And fixed to the ceiling surface and floor surface of the wall configuration position with nails or the like. Subsequently, another inner wall panel 10A is arranged next to the fixed inner wall panel 10, and at this time, the elastic fixing material 41 fits between the concave portions 23, 23A of the adjacent inner wall panels 10, 10A. Then, the upper and lower sides of the inner wall panel 10A are fixed to the ceiling surface and the floor surface in the same manner as described above. An adhesive may be applied to the recess 23A and the joint surface 22A of the inner wall panel 10A. Usually, the inner wall panel 1 is provided at a required width.
When the required number of 0s are arranged in parallel, when installing the panel 10 in the middle, the work can be performed from the lateral direction of the panel 10 using the extra space on the left and right of the panel 10, but depending on the floor plan and the construction procedure, In some cases, only a single panel installation space remains in the panel 10 installed in the panel. Then, the last panel 10 is arranged by being pushed into the remaining space from the front side on the face material 15 side. By the way, in the case of the present invention, the radius of the elastic fixing member 41 protrudes from the concave portion 23 of the vertical frame member 21.
Therefore, in the case of the above-mentioned pushing, although there is resistance due to the protrusion, if the material, dimensions and the like are set in consideration of the degree of deformation of the elastic fixing member 41, the joining surface of the adjacent panel 10 will be 22 and the elastic fixing material 41
Is compressed and elastically deformed, so that the last panel 10 can be pushed. In addition, the compressed elastically deformable elastic fixing member 41 is restored by fitting between the concave portions 23 of the panel joining surface to fill the space 24 between the concave portions 23, 23, so that the space between the panels 10 is securely fixed. You. As described above, according to the joint structure between the inner wall panels according to the present invention, the vertical frame member is made of a steel plate free from warping or twisting due to aging, and the panel joint surface Panels are joined by forming vertically long recesses in the vertical frame member made of steel plate, and arranging and fitting an elastic fixing member having a cross-sectional shape substantially matching the space between the recesses. There is no distortion due to a change with time or humidity, a step or a shift due to the change, a beautiful appearance of the panel is maintained for a long time, and a cloth or the like adhered to the surface of the face material is not cut. Further, according to the present invention, joining between adjacent panels can be performed without performing rivets or welding, and when the last panel is pushed in from the front side, the panel is simply pushed in from the front side of the face material side. In this way, it is very easy to work up to the last panel, and it is possible to securely join the panels.
