Description

Technical Field

[0001] The present invention relates to the technical field of a positioning structure for a vertical joint material for attaching a panel body and a method for attaching the vertical joint material, which are used for attaching the panel body to a wall surface.

Background Art

[0002] Today, there are demands such as improving the design by attaching a panel body (decorative panel board) to a wall surface. In such a case, a locking projection provided on a vertical joint material fixed to the wall surface with screws is inserted and locked into a locking hole provided on the back surface of the panel body to attach the panel body to the wall surface (see, for example, Patent Document 1). However, when attaching the vertical joint material to the wall surface in this way, a locking hole is formed in the panel body in advance, and a vertical joint material with a locking projection formed in advance is carried into the site and the attachment work is carried out. In that case, it is necessary to attach the vertical joint materials adjacent to each other on the left and right to the wall surface in a state where the dimensions are accurately measured. Therefore, it is known to provide a horizontal frame between the left and right vertical joint materials and attach the vertical joint materials in a state where the dimensions are measured (see, for example, Patent Document 2).

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the case where the horizontal frame is provided, the horizontal frame and the vertical frame constituting the vertical joint members are connected via magnets, and with the connection state of the vertical and horizontal frames by the magnets remaining, the panel body is also configured to be connected by magnets. By configuring it in this way, it is made easy to disassemble. However, in this case, since not only the panel body but also the vertical and horizontal frames are connected using magnets, not only is a magnet with a strong magnetic attraction force required to maintain the connection state, but these constituent members must be configured using a material (ferromagnetic substance) having ferromagnetism such as steel, which limits the degree of freedom in material selection. Moreover, the horizontal frame remains assembled even after the panel body is attached and is not removed, resulting in problems such as an increase in the number of parts, and these are the problems to be solved by the present invention.

Means for Solving the Problems

[0005] The present invention was created for the purpose of solving these problems in view of the above circumstances. The invention of claim 1 is a vertical joint member for attaching a panel body, wherein first and second vertical joint members for attaching the left and right edge portions of the panel body are attached to a wall surface in an adjacent state with a gap therebetween on the left and right, and include a dimensioned cross member. With one end portion of the cross member being applied to the first vertical joint member previously attached to the wall surface, the second vertical joint member applied to the other end portion of the cross member is positioned as the attachment position of the second vertical joint member. It is a positioning structure of a vertical joint member for attaching a panel body, characterized by this. The invention of claim 2 is a positioning structure of a vertical joint member for attaching a panel body according to claim 1, characterized in that the positioning by the cross member is performed at at least two positions, upper and lower. The invention of claim 3 is a positioning structure of a vertical joint member for attaching a panel body according to claim 1 or 2, characterized in that applying the cross member to the first and second vertical joint members for positioning is the contact of the edge portions of the cross member with the vertical edge portions of the first and second vertical joint members. In the invention according to claim 4, notch grooves are formed in the longitudinal edge portions facing each other of the first and second longitudinal joint members, and applying the cross member to the first and second longitudinal joint members for positioning is a temporarily held fitting into the notch grooves formed in the first and second longitudinal joint members at the edge portion of the cross member. It is a positioning structure for a longitudinal joint member for attaching a panel body according to claim 1 or 2, characterized in that. In the invention according to claim 5, the panel body is attached by fitting holes formed in the panel body engaging with locking projections formed in the longitudinal joint member, and the notch groove is formed along with the cut-up processing of the locking projection. It is a positioning structure for a longitudinal joint member for attaching a panel body according to claim 4, characterized in that. In the invention according to claim 6, for attaching the longitudinal joint member to the wall surface, either the longitudinal joint member is directly attached to the wall surface or the longitudinal joint member is attached via a base material. When the cross member is selected to have one side surface flat and directly attached to the wall surface, it is the surface that abuts against the wall surface. When the other side surface is selected to be in a stepped thickness shape corresponding to the base material and attached via the base material, it is the surface that abuts against the wall surface. It is a positioning structure for a longitudinal joint member for attaching a panel body according to claim 1 or 2, characterized in that. The invention according to claim 7 is a method of attaching longitudinal joint members for attaching the left and right edge portions of a panel body to a wall surface in an adjacent state with a gap therebetween left and right. The method includes a step of attaching the first longitudinal joint member to the wall surface, a step of applying one end portion of a dimensioned cross member to the attached first longitudinal joint member, a step of applying the second longitudinal joint member to the other end portion of the applied cross member, and a step of attaching the second longitudinal joint member positioned by the application to the wall surface, which are sequentially executed. The cross member is removed either before, during, or after the step of attaching the second longitudinal joint member to the wall surface. It is a method of attaching longitudinal joint members for attaching a panel body, characterized in that.

Advantages of the Invention

[0006] By adopting the invention of claim 1, when attaching the first and second vertical joint members for attaching the left and right edge portions of the panel body to the wall surface in a dimensioned state in the left and right directions, with one end portion of the dimensioned cross member applied to the first vertical joint member previously attached to the wall surface, and the second vertical joint member applied to the other end portion of the cross member, the positioning of the second vertical joint member is achieved. As a result, the positioning operation of the second vertical joint member is simplified, and workability can be improved. By adopting the invention of claim 2, by performing the positioning of the second vertical joint member using the cross member at at least two locations, upper and lower, the positioning of the second vertical joint member with respect to the first vertical joint member can be performed while maintaining parallelism, enabling highly accurate positioning to be easily achieved. By adopting the invention of claim 3, the operation of applying the cross member to the first and second vertical joint members for positioning can be performed by abutting the first and second vertical edge portions of the cross member edge against the vertical edge portions of the first and second vertical joint members, which is simple and can improve workability. By adopting the invention of claim 4, the operation of applying the cross member to the first and second vertical joint members for positioning can be performed by fitting the edge portion of the cross member into the notch grooves formed in the vertical edge portions of the first and second vertical joint members. As a result, positioning can be performed while temporarily holding the cross member, improving workability. By adopting the invention of claim 5, the notch grooves for positioning formed in the vertical joint members are formed in association with raising the locking protrusions formed in the vertical joint members for attaching the panel body. As a result, the notch grooves formed in association with forming the locking protrusions are effectively utilized as positioning grooves, eliminating the need to form dedicated notch grooves and simplifying the structure. By adopting the invention of claim 6, when, as a mode of attaching the vertical joint material to the wall surface, a mode of directly attaching the vertical joint material to the wall surface and a mode of attaching the vertical joint material via an underlay material are selected, if a horizontal member is selected such that one side surface is flat and is directly attached to the wall surface, it becomes the surface used in this case, and if the other side surface is formed in a stepped thickness shape to correspond to the underlay material and is attached via the underlay material, it becomes the surface used in this case. As a result, regardless of which mode is selected, only one type of horizontal member needs to be prepared, which not only reduces the number of parts but also contributes to an improvement in workability. By adopting the invention of claim 7, as a method for attaching the first and second vertical joint materials for attaching the left and right edge portions of the panel body to the wall surface in a state where the dimensions are taken left and right, a step of attaching the first vertical joint material to the wall surface, a step of applying one end portion of the horizontally dimensioned horizontal member to the attached first vertical joint material, a step of applying the second vertical joint material to the other end portion of the applied horizontal member, and a step of attaching the second vertical joint material positioned by this application to the wall surface are sequentially executed. Moreover, the horizontal member is removed either before, during, or after the step of attaching the second vertical joint material to the wall surface. As a result, the horizontal member for positioning the second vertical joint material can be reused repeatedly, and the number of parts can be reduced.

Mode for Carrying Out the Invention

[0008] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, 1 is a panel body, and the panel body 1 is attached and fixed to the wall surface W of a building via a vertical joint material 2 provided with a gap on the left and right. First, in the first embodiment, the vertical joint material 2 is not directly attached and fixed to the wall surface W, but is attached and fixed to the wall surface W via a base material 3 directly attached and fixed to the wall surface W via screws 3a, and is interposed between the wall surface W and the vertical joint material 2. It is attached and fixed to the wall surface W via screws (screws, fasteners) 2a. And the panel body 1 is configured to be attached to the wall surface W by fitting and locking locking holes 1a provided on the back surface (the surface facing the wall surface W) of the left and right edge portions of the panel body 1 into a pair of left and right locking protrusions 2d provided on the left and right vertical edge portions 2f of the vertical joint material 2 as described later. On the other hand, the one in the fourth embodiment described later does not use the base material 3, and the vertical joint material 2 is directly attached to the wall surface W via screws 2a.

[0009] First, in the first embodiment, horizontally long flat ceiling-side members and floor-side members (ceiling rail members, floor rail members) 4 and 5 are attached to the upper and lower edge portions of the wall surface W via screws 4a and 5a. On the other hand, the base material 3 is formed in a vertically long flat plate shape with the same thickness as the ceiling-side member 4 and the floor-side member 5 (for example, 1 mm), and is attached to the wall surface W via screws 3a in a state where it is not laminated with the ceiling-side member 4 and the floor-side member 5 between the lower edge 4b of the ceiling-side member 4 and the upper edge 5b of the floor-side member 5. On the other hand, the vertical joint member 2 is set to be narrower in the left-right width than the base material 3 and is in a vertically long flat plate shape. By being applied to the surface (front surface, front) of the screw-fixed base material 3, the base material 3 is arranged in a state of being interposed between the wall surface W and the vertical joint member 2, and is attached and fixed to the wall surface W via screws 2a. However, the upper and lower edge portions 2b and 2c of the vertical joint member 2 are set to be attached and fixed to the wall surface W via screws 2a in a state of being polymerized (laminated) from the surface side with respect to the ceiling-side member 4 and the floor-side member 5. And the vertical joint member 2 is attached in a state of interposing the base material 3 in this way, so that the upper and lower edge portions 2b and 2c are attached and fixed in a state of being laminated on the ceiling-side member 4 and the floor-side member 5, and are attached and fixed to the wall surface W in a state of being raised by the thickness of the ceiling-side member 4 and the floor-side member 5. In this case, the positions of the screws 2a for fixing the vertical joint member 2 are arranged so that a pair of them are in a state of being arranged side by side left and right and are respectively located on the vertical column line X in a vertically aligned row.

[0010] Furthermore, a plurality of locking protrusions 2d are formed in the vertical joint member 2 with gaps in the vertical direction in a state where the left and right vertical edge portions 2f are notched, and the left and right locking protrusions 2d are formed in a state of being located or substantially located on the vertical column line X of the screw 2a. And the panel body 1 has locking holes 1a formed at both left and right ends of the back surface (rear surface, back) of the panel body 1 facing the wall surface W. By locking the locking holes 1a to the locking protrusions 2d, the panel body 1 can be attached to the wall surface W via the vertical joint member 2. In this case, the locking protrusion 2d formed on the vertical joint material 2 is formed by performing a raising process on a long flat plate material using a press machine. However, at the vertical edge 2f of the portion where the locking protrusion 2d of the vertical joint material 2 is formed, a notch groove 2e in a state where the locking protrusion 2d serves as the bottom edge of the groove is formed by a punching process executed during the raising process of the locking protrusion 2d.

[0011] In this way, the panel body 1 will be attached to the wall surface W using the vertical joint material 2 with the notch groove 2e formed. In that case, a pair of left and right vertical joint materials 2 will be attached in an adjacent state with a gap therebetween left and right. When such a pair of left and right vertical joint materials 2 are the first and second vertical joint materials 21 and 22, first, with the first vertical joint material 21 attached to the wall surface W, the second vertical joint material 22 is positioned using the horizontal member 6, and the positioned second vertical joint material 22 is attached to the wall surface W via the screws 2a.

[0012] In that case, the horizontal member 6 is formed of a flat plate material that is long in the left - right direction and dimensioned to the length required for positioning the second vertical joint material 22 and has substantially the same thickness as the base material 3. When attaching and constructing the vertical joint material 2, either an aspect (specification) of attaching it to the upper surface of the base material 3 fixed to the wall surface W by screws as in the first embodiment of the present invention or an aspect of directly attaching it to the wall surface W without the base material 3 as in the fourth embodiment described later is selected. However, the horizontal member 6 is considered to be usable regardless of which attachment aspect of the vertical joint material 2 is selected.

[0013] One side surface 6a in the front - rear (front - back) direction of the horizontal member 6 is planar, and it is used as the surface that contacts the wall surface W when the aspect of directly attaching the vertical joint material 2 to the wall surface W in the fourth embodiment described later without using the base material 3 is selected. On the other hand, the second surface 6b on the other side has a thickness equal to the thickness of the cross member 6 due to the upper and lower edge portions 6ba being folded back in a laminated (superposed) manner. However, the intermediate portion 6bb between the upper and lower edge portions 6ba has no folding back and is in a stepped and thin state with a thickness equal to that of the cross member 6. In the mode where the vertical joint member 2 is selected to be attached to the wall surface W with the base material 3 of the first embodiment provided, the upper and lower edge portions 6ba are configured to be used as the surfaces that contact the wall surface W.

[0014] Furthermore, the left and right edge portions 6c of the cross member 6 have notches 6d formed in a state extending from the upper and lower edge portions 6ba to the intermediate portion 6bb, with a length exceeding the left and right widths by which the base material 3 extends left and right with respect to the vertical joint member 2. With this configuration, the left and right edge portions 6c of the cross member 6 also have a thickness equal to only that of the single-plate intermediate portion 6bb on the second surface 6b side, similar to the first surface 6a, resulting in a thin and stepped state with respect to the upper and lower edge portions 6ba. And the second surface 6b becomes the surface that contacts the wall surface W when the mode in which the vertical joint member 2 is attached via the base material 3 as described above is selected. In that case, the surface portions of the upper and lower edge portions 6ba having a thickness equal to that of two cross members 6 contact the wall surface W, while the surface portions of the left and right edge portions 6c having a thickness equal to that of one cross member contact the surface of the base material 3.

[0015] Regarding the vertical joint member 2 configured in this way, the cross member 6 is used to position the second vertical joint member 22 with respect to the previously attached first vertical joint member 21, and then it is attached and fixed using screws 2a. The process example will be described with reference to FIG. 10. As described above, for the base material 3, before attaching the first vertical joint member 21, it is attached to the wall surface W via screws 3a, and with the base material 3 attached, the first vertical joint member 21 is attached to a predetermined position via screws 2a.

[0016] After that, the second vertical joint member 22 will be attached to a position with a lateral gap relative to the first vertical joint member 21, so it is necessary to position the second vertical joint member 22. Therefore, a plurality of the cross members 6 (three are used in the drawing, but two may also be used) are prepared, and with the second surface 6b of the cross member 6 in contact with the wall surface W, one end edge portion 6c in the lateral direction is fitted into the notch groove 2e of the first vertical joint member 21. At this time, by abutting the edge of one end edge portion 6c in the lateral direction of the cross member 6 against the base end portion of the locking projection 2d, the cross member 6 is accurately positioned. Since the abutting of this edge becomes the base end portion of the standing projection 2d, it is easy to abut. And the cross member 6 is temporarily held by fitting one end edge portion 6c in the lateral direction into the notch groove 2e. If necessary, the operator may support the cross member 6 in a pressing manner so that the cross member 6 does not fall off. By similarly fitting the notch groove 2e of the second vertical joint member 22 in a state of being in contact with the surface of the base material 3 that has been previously screwed and fixed to the other end edge portion 6c in the lateral direction of the cross member 6 supported in this way, the second vertical joint member 22 is positioned in the lateral direction with respect to the first vertical joint member 21. By attaching and fixing the positioned second vertical joint member 22 to the wall surface W via the screws 2a, the second vertical joint member 22 can be attached in a positioned state.

[0017] And such positioning work using the cross member 6 of the second vertical joint member 22 is performed at a plurality of locations in the vertical direction (at least two locations), so that the second vertical joint member 22 can be positioned in a parallel state without inclining with respect to the first vertical joint member 21. And such positioning work at a plurality of positions up and down can be carried out in the normal standing working posture of the operator, and there is no need to force the positioning work on the ceiling side where one cannot reach. After the second vertical joint member 22 is positioned in this way, the second vertical joint member 22 is attached and fixed by screwing. However, the cross member 6 used for the positioning is to be removed from the first and second vertical joint members 21 and 22 before, during, or after the attachment work of the second vertical joint member 22 by screwing. After the second longitudinal joint member 22 is positioned with respect to the first longitudinal joint member 21 in this way, as the next step, the second longitudinal joint member 22 becomes the first longitudinal joint member 21, and a new longitudinal joint member 2 is made with the second longitudinal joint member 22 as the starting point. Similarly, the positioning and attachment work using the horizontal member 6 is repeated.

[0018] In the embodiment configured as described above, when attaching the first and second longitudinal joint members 21 and 22, which are longitudinal joint members 2 for attaching the left and right edge portions of the panel body 1, to the wall surface in a state where the left and right opposing spaces are positioned, one end portion 6c in the left - right direction of the dimensioned horizontal member 6 is applied to the first longitudinal joint member 21 previously attached to the wall surface, and with the second surface 6b of the horizontal member 6 in contact with the wall surface W, the second longitudinal joint member 22 is applied to the other end portion 6c in the left - right direction. Thus, the second longitudinal joint member 22 is positioned with respect to the first longitudinal joint member 21. In this positioned state, the second longitudinal joint member 22 can be fixedly attached via the screw 2a. As a result, the positioning work of the second longitudinal joint member 22 is simplified, and workability can be improved. And in this case, by performing the positioning work of the second longitudinal joint member 22 using the horizontal member 6 at at least two locations, the positioning of the second longitudinal joint member 22 with respect to the first longitudinal joint member 21 can be made while maintaining a parallel state, enabling highly accurate positioning to be easily achieved.

[0019] And in this case, as a method for attaching the first and second longitudinal joint members 21 and 22 for attaching the left and right edge portions of the panel body 1 to the wall surface in a state where the left and right dimensions are taken, · A step of attaching the first longitudinal joint member 21 to the wall surface W, · A step of fitting and incorporating one end edge portion 6c in the left - right direction of the dimensioned horizontal member 6 into the notch groove 2e of the attached first longitudinal joint member 21, · A step of fitting and incorporating the notch groove 2e of the second longitudinal joint member 22 into the other end edge portion 6c in the left - right direction of the horizontally - incorporated horizontal member 6, · A step of attaching the second longitudinal joint member 22 positioned by this fitting and incorporation to the wall surface via the screw 2a, are sequentially executed, and for the horizontal member 6 used for the positioning, the second vertical joint member 22 is removed either before, during, or after the step of attaching it to the wall surface W. As a result, the horizontal member 6 for positioning the second vertical joint member 22 can be repeatedly reused, reducing the number of parts.

[0020] In this way, to position the second vertical joint member 22 with respect to the first vertical joint member 21 using the horizontal member 6, the left and right edge portions 6c of the horizontal member 6 are applied to the first and second vertical joint members 21 and 22. In this embodiment, to position this horizontal member 6, the edge portions 6c of the horizontal member 6 are inserted and incorporated into the notch grooves 2e formed in the first and second vertical joint members 21 and 22. Since the notch grooves 2e are formed along with the formation of the locking protrusions 2d, the notch grooves 2e can also be effectively used for positioning, eliminating the need to form dedicated notch grooves and simplifying the structure. Of course, when the left and right edge portions 6c of the horizontal member 6 are inserted and incorporated into the notch grooves 2e and applied in the case of implementing the present invention, instead of the notch grooves 2e formed along with the formation of the locking protrusions 2d, dedicated notch grooves 2ea may be formed as in the second embodiment shown in FIG. 11.

[0021] Furthermore, applying the horizontal member 6 to the first and second vertical joint members 21 and 22 for positioning, as in the third embodiment shown in FIG. 12, the left and right edge portions 6c of the horizontal member 6 are made to abut against the vertical edge portions 2f of the first and second vertical joint members 21 and 22, and the present invention can also be implemented in this way. Even in this case, the positioning work is simple and the workability can be improved.

[0022] In each of the above embodiments, the vertical joint member 2 is attached with the base material 3 intervening. However, as in the fourth embodiment shown in FIG. 13, even when there is no base material 3 and the vertical joint member 2 is directly attached to the wall surface W, it is configured to be able to perform the positioning using the horizontal member 6. In this case, the horizontal member 6 is to be positioned on the second vertical joint member 22 in a fitting state where it is fitted into the notch groove 2e by being inserted into the first vertical joint member 21 that has been previously attached. However, in this situation, since there is no base material 3, the horizontal member 6 is positioned with its first surface 6a, which is set to be flat, in contact with the wall surface W.

[0023] Furthermore, it may be configured as in the fifth embodiment shown in Fig. 14. In this case, the base material 3 is not used, and the vertical joint member 2 is directly attached and fixed to the wall surface W. In that case, with the second surface 6b of the horizontal member 6 in contact with the wall surface W, one edge portion 6c in the left - right direction is temporarily fixed to the first vertical joint member 21 using screws 2a in a temporarily fixed state. Subsequently, by similarly screwing the other edge portion 6c of the horizontal member 6 in the left - right direction to the second vertical joint member 22, the second vertical joint member 22 can be positioned. By screwing the positioned second vertical joint member 22, it can be attached and fixed in the positioned state. And the horizontal member 6 that has been screwed for positioning purposes may be removed at any stage before, during, or after the screwing operation of the second vertical joint member 22. In this way as well, the positioning and attachment of the second vertical joint member 22 can be easily performed.
