Description

[Technical Field]

[0001] The present invention relates to an adjuster for fixing studs at intervals to a base wall. [Background technology]

[0002] A known partition wall structure is one in which wall panels are attached to a wall base that includes a pair of upper and lower runner members, a number of studs (rough joists) that engage with the upper and lower runner members, and vibration-proof members that are placed across the studs at intervals.The wall panels are fastened to the studs with screws.

[0003] To use such a wall base for a recessed wall, a position-adjustable connecting fitting is used to fix the stud material to a base wall such as a skeleton wall (see, for example, Patent Document 1). The recessed wall of Patent Document 1 has anchor holes drilled in the base wall, and connecting fittings connected to the stud material are attached to the anchor holes. The connecting fittings include two rods with threaded portions, a turnbuckle connecting the two rods, a notched pipe for fixing the base end rod to the anchor hole, and a pair of washers for fixing the tip end rod to the stud material. With such connecting fittings, the connecting fittings can be extended or retracted by rotating the turnbuckle, making it possible to adjust the distance between the base wall and the stud material.

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 3-41030 Summary of the Invention [Problem to be solved by the invention]

[0005] In Patent Document 1, unevenness in the base wall can be absorbed by adjusting the length of the connecting fittings, but the structure of the connecting fittings is complex, which means that manufacturing and installation require a lot of effort.

[0006] From this perspective, an object of the present invention is to provide an adjuster that has a simple structure and can be easily installed. [Means for solving the problem]

[0007] The present invention to solve the above problem is an adjuster comprising a bottom plate portion that is fixed to the base wall, and a pair of protruding plate portions that protrude from both the left and right ends of the bottom plate portion toward the stud material, and the protruding plate portions have multiple screw holes formed in them for fixing the stud material. The adjuster of this invention allows you to easily adjust the distance between the base wall and the stud by simply fastening the bottom plate to the base wall with screws and then abutting the stud in the desired position against the protruding plate and fastening with screws. In addition, the adjuster is a single piece of material that is U-shaped in plan view, making its construction simple.

[0008] In the adjuster of the present invention, it is preferable that the screw holes are arranged linearly at intervals in the direction of extension of the extension plate portion. With this configuration, the stud material can be fixed in the desired accurate position relative to the base wall.

[0009] In the adjuster of the present invention, it is preferable that the screw holes formed in one of the overhanging plate portions are positioned at positions offset in the overhang direction relative to the screw holes formed in the other overhanging plate portion. This configuration prevents interference between the tips of the screws when fastening the stud material from both sides with screws.

[0010] In the adjuster of the present invention, the protruding plate portion is preferably cuttable with metal snips. This configuration allows the protruding length of the protruding plate portion to be increased, thereby increasing the adjustable distance between the base wall and the stud. By cutting the protruding plate portion according to the distance between the base wall and the stud, the tip of the protruding plate portion can be prevented from protruding from the surface of the stud. [Effects of the Invention]

[0011] The adjuster according to the present invention has a simple structure and can be easily installed. [Brief explanation of the drawings]

FIG.

[0013] An adjuster according to an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIG. 4, the adjuster 1 according to this embodiment is a metal fitting used to construct a subfloor wall by installing studs 6 at a predetermined interval on a base wall 2. As shown in FIG. 6, the studs 6 are suspended between upper and lower runners 5, 5, arranged parallel to each other at a predetermined interval. The lower runner 5 is laid on the floor 3, and the upper runner is arranged along the underside of the upper structure 4. In this embodiment, the base wall 2, floor 3, and upper structure 4 are made of reinforced concrete. The studs 6 have a rectangular cross section and include long side wall surfaces 7a, 7a and short side wall surfaces 7b, 7b. The studs 6 are arranged so that the long side wall surface 7a faces the surface of the base wall 2 at a predetermined interval. Wall panels are installed on the long side wall surface 7a on the interior side.

[0014] First, we will explain the configuration of the adjuster 1. As shown in Figures 1 to 3, the adjuster 1 has a groove shape in plan view, and includes a bottom plate portion 10 and a pair of protruding plate portions 20, 20.

[0015] The bottom plate portion 10 is a portion that is fixed to the surface of the base wall 2, and corresponds to the bottom of the groove. The bottom plate portion 10 has a rectangular shape when viewed from the front. Screw holes 11 are formed in the bottom plate portion 10. Screws V are inserted through the screw holes 11 to fix the adjuster 1 to the base wall 2. A plurality of screw holes 11 (two in this embodiment) are provided. The screw holes 11 are located in two places, the lower left and upper right, when viewed from the front of the bottom plate portion 10 (as viewed from the stud material 6 side). The number and positions of the screw holes 11 are not limited to the shape of this embodiment. Three or more screw holes 11 may be provided depending on the weight of the wall finishing material and the shape of the stud material, and the arrangement positions can also be changed as appropriate.

[0016] The protruding plate portions 20 are portions for fixing the stud material 6, and protrude from both the left and right ends of the bottom plate portion 10 toward the stud material 6 when viewed from the front. The protruding plate portions 20 have a rectangular shape when viewed from the side, and have the same height as the bottom plate portion 10. The protruding plate portions 20 are bent at right angles to connect to both the left and right ends of the bottom plate portion 10. The pair of protruding plate portions 20 are parallel to each other. The pair of protruding plate portions 20 abut against the short side wall surfaces 7b of the stud material 6 from the outside on the left and right, respectively, and sandwich the stud material 6 from the left and right.

[0017] The overhanging plate portion 20 is formed with screw holes 21. Screws V for fixing the stud material 6 to the adjuster 1 are inserted through the screw holes 21. A plurality of screw holes 21 are formed. The plurality of screw holes 21, 21... are linearly arranged at intervals in the overhanging direction of the overhanging plate portion 20 to form a hole row 22. The hole row 22 is composed of five screw holes 21 arranged linearly at predetermined intervals. The hole rows 22 are formed on the upper and lower sides of the overhanging plate portion 20. When distinguishing between the upper and lower hole rows 22, the upper hole row 22 is referred to as the "upper hole row 22a" and the lower hole row 22 is referred to as the "lower hole row 22b." The screw holes 21 formed in one overhanging plate portion 20 are positioned offset in the overhanging direction from the screw holes 21 formed in the other overhanging plate portion 20. Specifically, the upper hole row 22a formed in one of the overhanging plate portions 20 is formed at the same height as the upper hole row 22a formed in the other overhanging plate portion 20, and is arranged offset in the overhanging direction. Furthermore, the lower hole row 22b formed in one of the overhanging plate portions 20 is formed at the same height as the lower hole row 22b formed in the other overhanging plate portion 20, and is arranged offset in the overhanging direction. The offset distance is half the length of the arrangement pitch of the screw holes 21. The upper hole row 22a of the same overhanging plate portion 20 is arranged offset in the overhanging direction from the lower hole row 22b. The upper hole row 22a of the right overhanging plate portion 20 is offset toward the base end (toward the bottom plate portion 10) from the lower hole row 22b (see FIG. 2(b)). The upper hole row 22a of the left overhanging plate portion 20 is offset toward the tip end from the lower hole row 22b (see FIG. 2(c)). The offset distance between the upper hole row 22a and the lower hole row 22b is also half the length of the arrangement pitch of the screw holes 21.

[0018] The protruding plate portion 20 has a thickness of 0.8 mm and can be cut with metal snips. As shown in Figure 4, when using the adjuster 1, the protruding plate portion 20 is cut in advance according to the recess dimensions of the recessed wall. As shown in Figure 4(a), the cutting line 23 is determined taking into consideration the positional relationship with the stud material 6 when the adjuster 1 is fixed to the base wall 2. The cutting line 23 is set at a position a predetermined length from the surface of the stud material 6 toward the base wall 2. The cutting line 23 is located closer to the interior of the room than the middle part of the width direction of the short side wall surface 7b. The protruding plate portion 20 is cut at the construction site using metal cutting shears. Because the protruding plate portion 20 can be cut at the construction site in this way, construction errors such as unevenness on the surface of the base wall 2 can be easily accommodated.

[0019] Next, the procedure for constructing a recessed wall using the adjuster 1 will be described with reference to Figures 5 and 6. First, a stud material 6 is placed between the upper and lower runners 5, 5. Here, the stud material 6 is not fixed to the runner 5, but is held slidably by the runner 5 so that it can slide along the runner 5.

[0020] Then, as shown in Figure 5(a), the adjuster 1 is screwed to the base wall 2 at the installation position of the stud material 6. Screws V are driven into the base wall 2 through the screw holes 11 from the indoor side of the bottom plate portion 10 (see Figure 1). The adjuster 1 may also be fixed to the base wall 2 with adhesive. The adjuster 1 is installed, for example, at a height of approximately 900 mm from the floor portion 3. With the adjuster 1 attached to the base wall 2, a cutting line 23 is set so that the protruding plate portion 20 has a predetermined length relative to the stud material 6 installed in accordance with the depth dimensions of the depth wall, and the adjuster 1 is cut at the construction site.

[0021] Thereafter, as shown in (b) of Figure 5, the stud material 6 is slid to the position of the adjuster 1. At this time, as shown in Figure 6, the middle part of the stud material 6 in the longitudinal direction is pulled, causing it to bend in an arc and slide. This allows the stud material 6 to move without getting caught on the overhanging plate part 20.

[0022] Next, as shown in FIG. 5(c), the stud material 6 is returned to its original linear shape and inserted between the pair of overhanging plate portions 20, 20. Then, the overhanging plate portion 20 is screwed to the stud material 6. The screws V are driven from the outside of the overhanging plate portion 20 through the screw holes 21 into the short side wall surface 7b of the stud material 6. In this embodiment, the screws V are fastened using the screw holes 21 on the base end side of the upper hole row 22a of the right overhanging plate portion 20 and the screw holes 21 on the tip end side of the lower hole row 22b of the left overhanging plate portion 20. In this way, by driving the screws V into diagonal positions of the overhanging plate portions 20 in a side view, the stud material 6 can be fixed in a balanced manner. Furthermore, interference between the tips of the screws V can be prevented.

[0023] The number and fixing positions of the screws V are not limited to the shapes of this embodiment and can be set as appropriate. If greater fixing strength is required, the number of screws V will be increased, but in this embodiment, the row of holes 22 formed in one overhanging plate portion 20 is offset in the overhang direction from the row of holes 22 formed in the other overhanging plate portion 20, preventing the tips of the screws V from interfering with each other.

[0024] As explained above, with the adjuster 1 of this embodiment, the distance between the base wall 2 and the stud material 6 can be easily adjusted by simply fastening the bottom plate portion 10 to the base wall 2 with screws and abutting the stud material 6 at a desired position against the overhanging plate portion 20 and fastening with screws. Also, because the adjuster 1 is a single member that is U-shaped in plan view, it has a simple configuration. Furthermore, because multiple screw holes 21 are arranged along the overhanging direction of the overhanging plate portion 20, there are many options for screw fastening positions, making installation easier.

[0025] Furthermore, because the screw holes 21 are arranged linearly at intervals in the protruding direction of the overhanging plate portion 20, there are many options for screw fastening positions, and the stud material 6 can be fixed at the desired precise distance from the base wall 2. The screw holes 21 formed in one overhanging plate portion 20 are positioned offset in the protruding direction from the screw holes 21 formed in the other overhanging plate portion 20, so that when the stud material 6 is fastened with screws from both sides, the tips of the screws V can be prevented from interfering with each other.

[0026] Furthermore, because the overhanging plate portion 20 can be cut with metal snips, the overhang length of the overhanging plate portion 20 in its initial state can be increased, thereby lengthening the adjustable separation distance between the base wall 2 and the stud material 6. By cutting the overhanging plate portion 20 according to the separation distance between the base wall 2 and the stud material 6, the tip of the overhanging plate portion 20 can be prevented from protruding from the surface of the stud material 6. This does not hinder the installation of the wall panel.

[0027] While the above describes the embodiments of the present invention, the present invention is not limited to the above embodiments, and appropriate design changes can be made to the materials, shapes, sizes, and the like without departing from the spirit of the present invention. In the above embodiment, the projecting plate portion 20 has an upper row of holes 22a and a lower row of holes 22b, but this is not limited to this. The row of holes 22 may be a single row, or may have three or more rows. Even when the row of holes 22 is a single row, the screw holes 21 on the left and right projecting plate portions 20 are offset from each other, preventing interference between the tips of the screws V driven from the left and right.
