Abstract

To provide a panel engaging metal fitting excellent at workability and earthquake resistance, and a load bearing structure using the panel engaging metal fitting.SOLUTION: A panel engaging metal fitting 70 includes: a body part 71 fixed to a stud 20; a first claw 72 formed at a front end of the body part; and an insertion piece 73 formed at a rear end of the body part. The first claw engages with a slit 11 of a front panel to engage the front panel to the stud. The insertion piece is to be inserted into the slit in a rear panel, and at least a part of a length of the insertion piece is substantially the same as a length of the slit. When an earthquake or the like occurs, the rear panel suppresses deformation of the stud as the insertion piece is fitted into the slit with almost no gap. Since the amount of deformation of the stud is small in comparison with a case where the panel is fixed to the stud only with the conventional panel engaging metal fittings, it is possible to prevent the front and rear panels from falling off from the stud, thereby improving earthquake resistance.SELECTED DRAWING: Figure 1

Description

【Technical Field】 【0001】 The present invention relates to a panel locking fitting used when locking a panel to a stud of a partition device and a load-bearing structure using the panel locking fitting. 【Background Art】 【0002】 In a partition device for partitioning a space into an appropriate width by connecting a plurality of panels in their width direction (left and right direction), each panel is locked to a stud via a panel locking fitting. Specifically, the panel locking fitting is a plate-like member having claws for locking the front panel and claws for locking the rear panel, and is fixed to the side surface of the stud at a plurality of positions (for example, one by one vertically). Slits are formed on the inner surface of the panel in advance corresponding to the positions of the claws. An operator moves the panel in the direction of the panel locking fitting, passes the claws through the slits, and then moves the panel downward to hook the claws, thereby locking the panel to the stud (see Patent Document 1). 【0003】 In such a general panel locking fitting, when a large impact is applied to the stud due to an earthquake or the like, the stud may be greatly deformed, and the panel may come off the stud and fall off. Therefore, for example, Patent Document 2 discloses a dropout prevention tool fixed to the mesh groove between the left and right panels. This dropout prevention tool allows in-plane displacement of the panel and restricts out-of-plane displacement, and can prevent the situation where the panel drops off the stud. 【Prior Art Documents】 【Patent Documents】 【0004】 【Patent Document 1】 Japanese Unexamined Patent Application Publication No. 2007-255017 【Patent Document 2】 Japanese Unexamined Patent Application Publication No. 2017-214778 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0005】 However, the technology disclosed in Patent Document 2 has the problem that the process of fixing the fall prevention device to the stud is time-consuming. From the standpoint of ease of installation, it is preferable that the panel can be secured to the stud simply by hooking the panel onto the claws of the panel locking bracket, as in the conventional method. 【0006】 The present invention aims to provide a panel fastening fitting and a load-bearing structure using the panel fastening fitting that are excellent in terms of ease of installation and seismic resistance, taking these problems into consideration. [Means for solving the problem] 【0007】 The panel locking fitting of the present invention is a panel locking fitting for locking front and rear panels to a stud, comprising a main body fixed to the stud, a first claw formed at the front end of the main body, and an insertion piece formed at the rear end of the main body, wherein the first claw hooks into a slit in the front panel to lock the front panel to the stud, and the insertion piece is inserted into the slit in the rear panel, and at least a portion of its length is substantially the same as the length of the slit. Furthermore, the insertion piece is characterized by having a second claw that catches on the slit to lock the rear panel to the stud. Furthermore, the insertable piece is characterized by having a bent portion formed by bending horizontally at its tip. Furthermore, the main body is equipped with a positioning projection and an opening, and the positioning projection is fitted into a recess formed at a predetermined position on the stud, and the main body is fixed to the side surface of the stud by a fixing means through the opening. The panel locking fitting of the present invention is a panel locking fitting for locking front and rear panels to a stud, and comprises at least a first fitting having a first main body fixed to the stud and a first claw formed at the front end of the first main body, and a second fitting having a second main body fixed to the stud and an insertion piece formed at the rear end of the second main body. The first main body and the second main body are fixed to the same plane along the front-rear direction among the multiple planes that constitute the stud, The first claw engages with the slit in the front panel to lock the front panel to the stud, and the insertion piece is inserted into the slit in the rear panel, characterized in that at least a portion of its length is substantially the same as the length of the slit. Furthermore, the insertion piece is characterized by having a second claw that catches on the slit to lock the rear panel to the stud. Furthermore, the insertable piece is characterized by having a bent portion formed by bending horizontally at its tip. The load-bearing structure of the present invention is characterized by comprising a stud, a panel locking fitting according to claim 1 or 5 fixed to the stud, and the rear panel with the insertion piece inserted into the slit. [Effects of the Invention] 【0008】 The insertion piece has a length that is substantially the same as the length of the slit, at least a portion of which is substantially the same, and fits almost seamlessly into the slit of the rear panel, so that the stud and the rear panel are pseudo-connected via the main body and the insertion piece. Therefore, if an earthquake or the like occurs while the front and rear panels are locked to the stud, the deformation of the stud can be suppressed by the rear panel. In this way, compared to the case where the front and rear panels are locked to the stud using only conventional panel locking fittings, the amount of deformation of the stud during an earthquake or the like is reduced according to the panel locking fitting of the present invention and the load-bearing structure using this panel locking fitting, so that the front and rear panels do not fall off the stud and the seismic resistance can be improved. Furthermore, since the front and rear panels can be secured to the stud simply by inserting the insertion piece into the slit of the rear panel and hooking the first claw into the slit of the front panel, the ease of installation is improved compared to using conventional anti-detachment devices. Furthermore, by hooking the first claw into the slit in the front panel, it is possible to prevent the front panel from curving in the front-to-back direction. 【0009】 If the insertion piece is equipped with a second claw, not only will the insertion piece fit into the slit with almost no gap, but the back panel can also be hooked onto the second claw, further preventing the back panel from falling off the stud in the event of an earthquake or other incident. If the insertion piece is equipped with a bend, even if a force in the front-to-back direction is applied to the rear panel during an earthquake or the like, the bend will catch on the inner surface of the rear panel, further preventing the rear panel from falling off the stud. By utilizing the positioning protrusions provided on the main body, positioning the panel locking bracket when fixing it to the stud becomes easier, improving workability. Furthermore, by using a single opening provided on the main body, the panel locking bracket can be fixed to the side of the stud with a single bolt, screw, or other well-known fastening means, thus reducing the number of bolts or screws used. The panel fastening bracket may be composed of a pair of brackets, a first bracket and a second bracket.

As shown in FIG. 1, the partition device 100 is generally composed of a panel 10, a stud 20, a ceiling rail 40, a floor rail 60, etc. The left and right ends of the panel 10 are supported by the studs 20 using the panel locking fittings 70, and the upper and lower ends of the panel 10 are supported by the ceiling rail 40 and the floor rail 60. 【0012】 As shown in Figure 2, the panel 10 is a rectangular plate. The structure of the panel 10 is well known, so a detailed explanation is omitted. The material of the panel 10 is not particularly limited, and for example, a paper honeycomb core, gypsum board, calcium silicate board, plywood, etc. can be used. The surface of the panel 10 may be covered with a surface material. Multiple (five in this embodiment) slits 11 are formed on the left and right side edges on the back side of the panel 10. The number of slits 11 can be changed as appropriate. The stud 20 is a vertically standing member, and the panel 10 is secured to its front and back. The structure of the stud 20 is well known, so a detailed explanation will be omitted, but in this embodiment, the stud 20 is a hollow member with a rectangular cross-section along the horizontal plane. A so-called square pipe may also be used as the stud 20. 【0013】 As shown in Figure 3, the panel locking fitting 70 comprises a main body 71, a first claw 72, and an insertion piece 73. The material of the main body 71, the first claw 72, and the insertion piece 73 is not particularly limited, but metals such as iron and aluminum or resin can be used. The main body 71 is made of a thin plate and has openings 74 at multiple locations therein. The main body 71 is fixed to the side of the stud 20 by well-known fastening means such as bolts and screws through the openings 74. The first claw 72 is provided at the front end of the main body 71 and engages with the slit 11 of the front panel 10 to lock the front panel 10 to the stud 20. A recess 75 is formed between the first claw 72 and the main body 71. 【0014】 The insertion piece 73 is inserted into the slit 11 of the rear panel 10 and is formed at the rear end of the main body 71. As shown in Figure 2(c), when the length of the slit 11 is L, as shown in Figure 3, at least a portion of the insertion piece 73 has a length L1 that is substantially the same as the length L of the slit 11. "Substantially the same" means that at least a portion of the insertion piece 73 can be inserted into the slit 11, and that the lengths L1 and L are equal to such an extent that there is virtually no gap between the insertion piece 73 and the slit 11. 【0015】 The procedure for securing the panel 10 to the stud 20 using the panel locking fitting 70 of the present invention will be described. First, as shown in Figure 4, the worker secures the conventional panel fastening bracket 80 to two locations on the upper and lower sides of the stud 20 using well-known fastening methods such as bolts and screws. Note that in Figures 4 to 7 and Figure 10, the panel fastening bracket 70, slit 11, etc. are depicted to a larger scale than their actual size for ease of understanding. Conventional panel locking brackets 80 have claws 82 of the same shape on the front and rear sides of the main body 81. A recess 83 is formed between the claws 82 and the main body 81. As shown in Figure 5(a), the worker moves the rear panel 10 toward the stud 20, inserts the claw 82 into the slit 11 as shown in Figure 5(b), and then moves the panel 10 downward as shown in Figure 5(c). This causes the rear panel 10 to fit into the recess 83, thereby locking the rear panel 10 to the stud 20. In this state, the rear panel 10 can be removed from the stud 20 by moving it upward and then backward. 【0016】 Next, as shown in Figure 6(a), the worker removes the panel locking fitting 70 of the present invention. Then, as shown in Figure 6(b), the insertion piece 73 is inserted into the slit 11 of the rear panel 10, and the main body 71 is fixed to the stud 20 by a well-known fixing means. The length L1 of the insertion piece 73 is substantially the same as the height L of the slit 11, and the insertion piece 73 fits into the slit 11 with almost no gap, so in this state the rear panel 10 cannot be removed from the stud 20. Next, as shown in Figure 6(c), the worker moves the front panel 10 toward the stud 20, inserts the claws 82 and the first claw 72 into the slit 11 as shown in Figure 7(a), and then moves the front panel 10 downward as shown in Figure 7(b). This causes the front panel 10 to fit into the recesses 83 and 75, thereby locking the front panel 10 to the stud 20. 【0017】 When the front and rear panels 10 are secured to the studs 20 using the panel fastening fitting 70 of the present invention, if an earthquake or the like occurs, the insertion piece 73 fits almost snugly into the slit 11, so the rear panel 10 suppresses the deformation of the studs 20. Compared to the case where the front and rear panels 10 are fixed to the studs 20 using only the conventional panel fastening fitting 70, the amount of deformation of the studs 20 is reduced, thus preventing the front panel 10 and the back panel 10 from falling off the studs 20. The shape of the insertion piece 73 is not limited to a rectangle as shown in Figure 3; for example, it may also be an arc shape as shown in Figure 8. As shown in Figure 6, the load-bearing structure of the present invention is composed of a stud 20, a panel locking fitting 70 fixed to the stud 20, and a rear panel 10 with an insertion piece 73 inserted into the slit 11. 【0018】 [Second Embodiment] A second embodiment of the panel locking bracket of the present invention will now be described, but parts that have the same configuration as in the first embodiment will be denoted by the same reference numerals and their descriptions will be omitted. As shown in Figure 9, this embodiment is characterized in that the panel locking fitting 90 is equipped with a second claw 91. This panel locking fitting 90 has a portion of the insertion piece 92 with a length L1 that is substantially the same as the length L of the slit 11, and is equipped with a second claw 91 on the upper part of the insertion piece 92. 【0019】 As shown in Figure 10(a), with the conventional panel locking brackets 70 fixed to the upper and lower sides of the stud 20, as shown in Figure 10(b), the worker rotates the main body 93 counterclockwise so that the rear side is lower than the front side, first inserting the second claw 91 into the slit 11, then fitting the rear panel 10 into the recess 94, and then as shown in Figure 10(c), inserting the insertion piece 92 into the slit 11 while rotating it clockwise, thereby fixing the main body 93 to the stud 20. By providing the second claw 91, the insertion piece 92 fits into the slit 11 with almost no gap, and the back panel 10 fits into the recess 94. This further reduces the amount of deformation of the stud 20 in the event of an earthquake or the like, and further prevents the back panel 10 from falling off the stud 20. 【0020】 [Third Embodiment] A third embodiment of the panel locking bracket of the present invention will now be described, but parts that have the same configuration as in the above embodiments will be denoted by the same reference numerals and their descriptions will be omitted. As shown in Figure 11, this embodiment is characterized in that the insertion piece 95 has a bent portion 96 formed by bending horizontally at its tip. The worker first inserts the bent portion 96 into the slit 11 of the rear panel 10, and then rotates the main body portion 97 horizontally by approximately 90 degrees to fix the main body portion 97 to the side of the stud 20. By providing the bent portion 96, even if a force in the front-to-back direction is applied to the panel 10 during an earthquake or the like, the bent portion 96 will catch on the inner surface of the rear panel 10, further preventing the rear panel 10 from falling off the stud 20. 【0021】 [Fourth Embodiment] A fourth embodiment of the panel locking bracket of the present invention will now be described, but parts that have the same configuration as in the above embodiments will be denoted by the same reference numerals and their descriptions will be omitted. As shown in Figure 12, this embodiment is characterized in that the main body 71 is equipped with a positioning projection 110 and an opening 111. 【0022】 As shown in Figure 13(a), a typical stud 20 has a pre-formed hole (recess) 112 for use when fixing the panel locking bracket. In the first embodiment described above, the worker used two openings 74 formed in the main body 71 to fix the panel locking bracket 70 to the side of the stud 20 using two bolts, screws, or other well-known fixing means. However, in this embodiment, as shown in Figure 13(b), the positioning projection 110 is fitted into the recess 112, and the panel locking bracket is fixed to the side of the stud 20 using one opening 111 in the main body 71 with one bolt, screw, or other well-known fixing means 113. By using the positioning projection 110, the positioning of the panel locking bracket becomes easier, and the number of bolts or other fixing means 113 used can be reduced, thereby improving workability. In this embodiment, the panel locking bracket may also be provided with positioning protrusions 110 on both the front and back surfaces of the main body 71, as shown in Figure 14. 【0023】 [Fifth Embodiment] A fifth embodiment of the panel locking bracket of the present invention will now be described, but parts that have the same configuration as in the above embodiments will be denoted by the same reference numerals and their descriptions will be omitted. As shown in Figure 15(a), this embodiment is characterized in that the panel locking bracket consists of a pair of brackets: a first bracket 120 on the right and a second bracket 130 on the left. 【0024】 The first fitting 120 has a first main body portion 121 that is fixed to the stud 20, and a first claw 122 formed at the front end of the first main body portion 121. Similar to the first embodiment, the first claw 122 hooks into the slit 11 of the front panel 10, thereby locking the front panel 10 to the stud 20. The second fitting 130 has a second main body portion 131 fixed to the stud 20 and an insertion piece 132 formed at the rear end of the second main body portion 131. The insertion piece 132 is inserted into the slit 11 of the rear panel 10, similar to the first embodiment, and at least a portion of its length L1 is substantially the same as the length of the slit 11. 【0025】 Various other shapes can be used for the first fitting 120 and the second fitting 130. For example, in Figure 15(b), the insertion piece 132 is equipped with a second claw 133. The second claw 133 hooks into the slit 11, thereby locking the rear panel 10 to the stud 20. Also, in Figure 16, the insertion piece 132 is equipped with a bent portion 134. The bent portion 134 is formed by bending horizontally at its tip. Figure 17 is characterized in that the panel locking fitting consists of a lower first fitting 140 and an upper second fitting 150, forming a pair. In this case, it is necessary to change the position in which the slit 11 is formed on the front panel 10 and the rear panel 10. [Industrial applicability] 【0026】 The present invention provides a panel fastening fitting and a load-bearing structure using the panel fastening fitting, which offer excellent workability and seismic resistance, and has industrial applicability.
