Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wall base structure. More specifically, a plurality of rails mounted with their longitudinal directions oriented laterally with respect to a wall where interlayer displacement can occur, and a first mounting that engages with the rails and is movable laterally along the rails The present invention relates to a wall base structure including a member and a second mounting member that is mounted on a wall-supporting stud or wall plate and is connected to the first mounting member.
[0002]
[Prior art]
Conventionally, as a technique related to the above-described wall foundation structure, for example, a stud fixture as described in JP-A-9-256590 is known. In this wall foundation structure, the first attachment member is slidably attached to a rail whose longitudinal direction is oriented in the lateral direction. The front / rear position adjustment piece with multiple locking parts protrudes from the mounting bracket, and the stud mounting amount is adjusted by locking the second mounting member attached to the stud at an appropriate position on the adjustment piece. ing.
[0003]
However, in such a wall foundation structure, it is necessary to bend the adjustment piece by engaging the second mounting member with a locking portion having a constant width. Therefore, in the above conventional structure, it is difficult to adjust the amount of dandruff during construction. Further, in order for the relative movement of the first mounting member with respect to the rail longitudinal direction to occur smoothly when the interlayer is displaced, it is necessary to take care that the first mounting member can smoothly slide in the rail.
[0004]
By the way, the wall to which the rail is attached is constituted by an ALC panel or the like attached to the casing in addition to the concrete wall of the casing itself. In addition, when supporting a plurality of ALC panels side by side in a housing, a rocking system that supports tilting (rocking) in the same direction as a sway system that supports the panel that is connected when the interlayer is displaced horizontally (sway), and There is. In the locking ALC panel, the distance between the rails attached to the ALC panel fluctuates when there is a large interlayer displacement. However, the conventional structure cannot follow the fluctuation between the rails, and the protection of the wall plate is insufficient. there were.
[0005]
[Problems to be solved by the invention]
In view of such a conventional situation, a first object of the present invention is to provide a wall base structure in which a rail and a stud oriented in a lateral direction are smoothly displaced and the amount of shading can be easily adjusted.
[0006]
A second object of the present invention is to provide a wall base structure that can protect a wall plate attached not only to a sway but also to a wall that is locked by interlayer displacement.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the feature of the wall foundation structure according to the present invention is that the rail engages with a plurality of rails mounted with the longitudinal direction oriented in the transverse direction with respect to the wall where the interlayer displacement can occur. In a configuration comprising a first mounting member that can move laterally along the rail, and a second mounting member that is mounted on a wall-supporting stud or wall plate and connected to the first mounting member, The mounting member has a disk and is screwed to the second mounting member via a male screw along the central axis of the disk, and the first mounting member is engaged with the rail at least at the lower part of the disk in a rotatable state. In addition, the distance between the first mounting member and the second mounting member in the central axis direction can be adjusted by relative rotation between the first mounting member or the second mounting member and the male screw.
[0008]
According to this characteristic configuration, the distance between the rail and the stud (the amount of fuzzing) can be easily adjusted after the first mounting member or the second mounting member and the male screw are relatively rotated. Further, since the disk can rotate at least with the male screw as the central axis, the movement of the disk along the longitudinal direction of the rail can occur not only by sliding but also by rolling motion. In particular, even when the rail and the disk using the elasticity of the folded portion are engaged as described later, when a load is applied to the disk in the longitudinal direction of the rail, the action of the moment around the central axis of the disk The rolling motion is smooth.
[0009]
Further, it is desirable that “the male screw is fixed to be non-rotatable relative to either the disk of the first mounting member or the second mounting member and is screwed to the other of the disk or the second mounting member”. . This is because, for example, the amount of blurring can be easily adjusted simply by rotating the “disk”.
[0010]
In configuring the rail and the disk, it is desirable that “the disk can be displaced upward with respect to the rail”. This is because even when an interlayer displacement having a large displacement width occurs, the displacement of the first and second mounting members and the rail in the vertical direction can be absorbed.
[0011]
The lower portion of the rail is provided with a folded portion for engaging the lower portion of the disk, and the interval between the upper portion of the folded portion and the main body of the rail is narrower than the interval between the lower portion of the folded portion and the disk. You may make it form narrower than thickness. In addition, a folding part for engaging the lower part of the disk is provided at the lower part of the rail, and the elasticity of the folding part may be used in which the folding part or a protrusion that presses against the rail body may be formed on the disk. This is because the engagement of the disks can prevent rattling noise between the rails and the disks and unnecessary rotation of the disks during normal times.
[0012]
Further, a plurality of wall foundation panels having the same width are arranged side by side in the lateral direction, and each rail is attached to the wall foundation panel at the same distance from one end of each wall foundation panel. It is attached so that it can tilt. According to this mounting structure, even if the wall foundation panel is largely locked, the mounting portion of each rail with respect to each wall foundation panel or the damage to the wall foundation panel or rail is avoided. In order to minimize the interval variation between the rails accompanying the locking of the wall foundation panel, it is desirable that the mounting position of the rails with respect to the wall foundation panel is the center in the width direction of the wall foundation panel.
[0013]
A cushioning material may be interposed between the rail and the wall. This is because, when the wall is composed of a plurality of ALC panels or the like, it is possible to prevent rattling noises that occur at the contact portions between the steps and the rails between the panels.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Next, the case where the wall foundation structure 1 is provided in the housing will be described with reference to FIGS.
[0015]
As shown in FIGS. 1, 3 and 4, in the wall foundation structure 1 according to the present invention, a plurality of ALC panels 3, which are wall base panels, are arranged in the horizontal direction and are attached to a casing (not shown). It is supported between and forms a wall 2. Interlayer displacement can occur in the housing, so interlayer displacement can also occur in the wall 2. Each ALC panel 3 is supported by a housing so as to cause the above-mentioned locking when the interlayer is displaced.
[0016]
A plurality of rails 7 are arranged at appropriate intervals in the vertical direction in a posture in which the longitudinal direction thereof is directed laterally with respect to each ALC panel 3 forming the wall 2, and are fastened by mounting screws 10. In addition, grooved upper runner 5 and lower runner 6 are fixed to the upper and lower portions of each ALC panel 3 via L-shaped runner mounting brackets 4 and tap screws 4a fixed by mounting screws 10, respectively. Has been. The upper and lower ends of each stud 11 are fitted so as to be slidable in the grooves of the upper runner 5 and the lower runner 6. The runner mounting brackets 4 and the rails 7 for mounting the runners 5 and 6 to each ALC panel 3 are attached by one mounting screw 10, and the runner mounting brackets 4 and 4 are attached to the ALC panel 3. The relative tilting of the rail 7 is possible. However, as long as these relative tilts are possible, one or one runner mounting bracket 4 and one rail 7 may be attached to one ALC panel 3 at two or more locations.
[0017]
Each ALC panel 3 has the same width, and the mounting position P of each rail 7 with respect to each ALC panel 3 by the mounting screw 10 is the center in the width direction of each ALC panel 3. In FIG. 1, a center line L passing through the mounting position P of each of the upper, middle and lower rails 7x, 7y, 7z coincides with the center line of each panel 3, and the distance W1 between the left end of the panel and the center line in each of the left and right panels 3 , W3 are equal to the distances W2, W4 between the right edge of the panel and the center line. For example, if the distances W2 and W4 between the right end of the panel and the center line L are different among the three or more ALC panels 3, the relative tilt angles of the ALC panels 3 and the rails are different at the time of locking as shown in FIG. Thus, there is a risk that the mounting portion at the mounting position P or the ALC panel 3 or the rail 7 may be damaged, but according to the present structure, these damages are avoided. In order to avoid damage at the mounting position P at the time of locking, the distances W2 and W4 need only be equal between the panels, and the mounting position P does not necessarily coincide with the center of each ALC panel. However, preferably, if the mounting position P passes through the center of each ALC panel 3, the variation in the distance between the upper, middle, and lower rails 7x, 7y, and 7z during locking is minimized.
[0018]
The studs 11 are attached to the rails 7 at their intersections via a first attachment member 21 and a second attachment member 24 that are connected to each other. Each first mounting member 21 includes a disk 22 and a male screw 23 protruding along the central axis of the disk 22. The disc 22 is provided with a plurality of through holes 22a in the circumferential direction. Further, a folded portion 7a is provided at the lower portion of the rail 7, and the disk 22 engages with the folded portion 7a at the lower portion.
[0019]
By the way, the distance d between the upper part of the folded part 7a and the main body of the rail 7 is formed narrower than the distance in the lower part of the folded part 7a and smaller than the thickness t of the disk 22. When the rail 7 and the disk 22 are engaged, the disk 22 is forcibly inserted into a narrow gap between the folded portion 7a and the rail body. By sandwiching the disk 22 with the elasticity of the folded-back portion 7a, unnecessary relative rotation of the disk 22 with respect to the rail 7 is prevented, and generation of rattling noise between the rail 7 and the disk 22 is prevented.
[0020]
The second mounting member 24 is formed with a pair of fitting portions 24a and 24a that are bent by 90 degrees at both ends of the plate-like member and have a constriction to be fitted to the folded ends 11a and 11a of the stud 11, respectively. It is. A female screw 25 that is screwed into the male screw 23 is integrally formed at the center of the second mounting member 24. Then, the male screw 23 and the female screw 25 are rotated relative to each other by the rotation of the disk 22, so that the distance between the rail 7 and the stud 11 in the axial direction of the male screw 23 (the amount of squeezing) can be adjusted.
[0021]
At the time of construction, the rail 7, the upper runner 5, and the lower runner 6 that are horizontally oriented are fixed to the plurality of ALC panels 3 via the mounting screws 10 and the runner mounting brackets 4. Further, in the state where the male screw 23 of the first mounting member 21 is screwed into the female screw 25 of the second mounting member 24, the folded end 11a and the fitting portion 24a are fitted. And the 2nd attachment member 24 is displaced below in the groove | channel of the stud 11, and the disk 22 is engaged with the folding | returning part 7a. Next, the disk 22 is rotated so that the amount of blur between the rail 7 and the stud 11 is set to an appropriate interval. Finally, the gypsum board 12 which is a wall board is attached to the stud 11 with a tap screw, thereby completing the basic wall construction.
[0022]
Here, the behavior when interlayer displacement occurs in the housing will be described. When interlayer displacement occurs in the housing, the state shown in FIG. 2 is obtained. In this case, the upper and lower mounting portions of the ALC panel 3 are displaced between the layers in the lateral direction, and each ALC panel 3 is in an oblique posture. As a result, the rails 7 are also displaced in the lateral direction.
[0023]
However, since the first attachment member 21 is attached to the gypsum board 12 via the second attachment member 24 and the stud 11, when the interlayer displacement occurs, the disk 22 extends in the lateral direction which is the longitudinal direction of the rail 7. It will roll or partly slide. Thus, since the relative movement of the stud 11 and the rail 7 and the upper and lower runners 5 and 6 is allowed, it is possible to prevent the plaster board 12 from being destroyed due to the interlayer displacement. Even if the interlayer displacement is large and the distance between the rails 7 in the vertical direction changes due to the sway of the ALC panel, the disc 22 can be displaced upward from the folded portion 7a. The board 12 is not destroyed.
[0024]
Next, another embodiment of the present invention will be further enumerated.
In the first embodiment, the rail 7 is provided on the housing and the housing. However, the rail 7 may be attached to a concrete wall of a frame that can cause interlayer displacement. Moreover, you may use wall base panels, such as an extrusion-molded cement board, instead of an ALC panel. Each panel may be attached by the sway method in addition to the locking method as described above.
[0025]
In the above embodiment, the male screw 23 is provided on the first attachment member 21 and the female screw 25 is provided on the second attachment member 24. However, the male screw 23 may be provided on the second mounting member 24 and the female screw 25 may be provided on the first mounting member 21. In the above-described embodiment, the male screw 23 is not rotatable relative to the disk 22. However, the relative rotation may be enabled. However, by making the relative rotation impossible, it is convenient that the amount of shading of the rail 7 and the stud 11 can be adjusted by the rotation of the disk 22.
[0026]
In the above embodiment, the runner mounting bracket 4 is used to mount the upper and lower runners 5 and 6 to the wall 2. However, as shown in FIG. 5, the rail 7 and the first and second mounting members 21 and 24 may be used to support the upper and lower runners 5 having a larger movement amount at the time of locking. Such an upper runner 5 and the fitting portion 24a of the second mounting member 24 are connected by a tap screw 24b, and in order to support the upper runner below the second mounting member 24, the second mounting member 24 is used. This can be supported from below the lower runner 6.
[0027]
In the above embodiment, each rail 7 is directly attached to the wall 2 with the attachment screw 10. However, as shown in FIG. 5, a band-shaped cushioning material 8 may be interposed between each rail 7 and the wall 2. In particular, the cushioning material 8 can reduce rattling noise caused by contact with the rail 7 at the stepped portion between the ALC panels 3 and 3.
[0028]
In the above embodiment, the distance d between the upper portion of the folded portion 7a and the main body of the rail 7 is formed smaller than the thickness t of the disk. However, the present invention is not limited to this, and a rib-like annular protrusion 22b may be formed on the disk 22 on the protruding side of the male screw 23 as shown in FIG. 6, and the protrusion 22b may be pressed against the folded portion 7a. The protrusion 22b may protrude from the opposite side of the male screw 23 to be brought into pressure contact with the rail body. However, the structure shown in FIG. 6 is desirable because of the stability of the rail 7 and the disk 22. In forming the protrusions 22c, they may be arranged in a dotted pattern around the male screw 23 as shown in FIG. Further, as shown in FIG. 8, a groove-like projection 7b may be provided inside the folded portion 7a. Furthermore, as shown in FIG. 9, the groove-like protrusion 7c may be formed separately from the folded portion 7a and attached to the folded portion 7a. In addition to the groove-like protrusion 7d in the folded portion 7a, a fine protrusion 22d such as an annular hairline may be formed on the surface of the disk 22. The groove-like protrusions 7c and 7d can be formed by extrusion molding of an aluminum material or plastic.
[0029]
In the said embodiment, although the 2nd attachment member 24 was attached to the stud 11, you may comprise so that this 2nd attachment member may be modified and attached to the wall board 12 directly. The material of the wall plate 12 is not limited to the gypsum board, and other materials such as a hollow panel can be used.
[0030]
【The invention's effect】
As described above, according to the characteristics of the wall foundation structure according to the present invention, it is possible to easily adjust the amount of fuzzing even after assembling via the male screw interposed between the disk and the second mounting bracket. . In addition, the relative movement between the rail and the first mounting member is achieved by rotating the disk around the male screw that adjusts this amount of fuzzing, and also adding the rolling motion of the disk to make the relative movement smoother. As a result, it has become possible to sufficiently prevent the destruction of the wall due to the interlayer displacement.
[0031]
Further, by making the disc displaceable upward with respect to the rail, the wall plate attached to not only the sway but also the wall to be locked can be protected by the interlayer displacement.
[0032]
Furthermore, by configuring the mounting positions of the plurality of wall foundation panels and the rails as described above, it is possible to prevent such mounting positions from being damaged.
