Description

[Technical Field]

[0001] The present invention relates to a reinforcing member, a building wall structure using the same, and a method for constructing a building wall. [Background technology]

[0002] Traditionally, lip-groove steel (C-shaped steel) has been used as studs placed inside building walls, such as partitions. Generally, studs made of lip-groove steel are cheaper than square steel, but they are weaker. Therefore, if a high load is applied from the out-of-plane direction to the stud, there is a risk that the stud may deform or twist, causing it to detach from the runners positioned above and below it.

[0003] Therefore, as a method to improve the strength of the studs, a method has been proposed in which a reinforcing device is fitted into the opening of the lip-groove steel (for example, Patent Documents 1 and 2).

[0004] Patent Document 1 describes a building wall structure in which a main body connected to a pair of first and second plate-like parts is positioned between a pair of edges (lips) of a stud, and the edges (lips) of the stud are sandwiched between the first and second plate-like parts. Patent Document 2 describes a building wall structure in which the reinforcing device includes a spacing maintenance part for preventing the spacing between a pair of edges (lips) on the open surface of the stud from narrowing, and an angle maintenance part for preventing deformation of the angles of the first and second corner parts located at both ends in the width direction of the closed surface (web) of the stud. It is also described that this angle maintenance part has a corner contact part that abuts against the inner surfaces of each of the first and second corner parts, and a connecting part that connects the corner contact parts to each other. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Patent No. 6430588 [Patent Document 2] Patent No. 7015688 [Overview of the project] [Problems that the invention aims to solve]

[0006] However, in the case of the building wall structure described in Patent Document 1, the structure acts only on a pair of edges (lips) of the stud to maintain the spacing between the edges (lips). Therefore, if a high load is applied to the flange of the stud, for example, there is a risk of deformation or twisting of the stud.

[0007] Furthermore, in the case of the building wall structure described in Patent Document 2, the corner contact portion of the reinforcing device contacts the inner surfaces of the first and second corner portions located at both ends in the width direction of the closed surface portion (web) of the stud, which presents the problem of difficulty in attaching the reinforcing device to the opening of the stud. Moreover, in the case of the building wall structure described in Patent Document 2, due to the above structure, it is difficult to move the reinforcing device to a desired position on the stud, and it is also difficult to stably fix the reinforcing device to the stud.

[0008] This invention has been made in view of the above circumstances, and aims to provide a reinforcing member that can suppress deformation and twisting of studs and allows for easy adjustment of the attachment and fixing position to the studs, as well as a building wall structure and a building wall construction method using the same. [Means for solving the problem]

[0009] To solve the above problems, the following reinforcing members, building wall structures, and building wall construction methods are provided. [1] A reinforcing member inserted into the opening of a stud made of lip grooved steel, A rectangular, flat, fixed plate portion comprising a first region and a second region that are spaced apart from each other and facing each other, A flat plate-shaped insertion portion connected to one end of the aforementioned fixing plate portion, A rising portion that extends from one end of the insertion portion, Equipped with, The first region of the fixed plate portion can abut against one outer surface of the pair of lip portions of the stud, and the second region can abut against the other outer surface of the pair of lip portions of the stud. The insertion portion protrudes in a direction orthogonal to the fixed plate portion from one end in a second direction orthogonal to a first direction, which is the direction in which the first region and the second region of the fixed plate portion face each other. At a first end portion of the insertion portion located on a side connected to the one end of the fixed plate portion, slits that are long in a direction parallel to the first direction are formed at both ends in the first direction. The lip portion of the stud can be inserted into the slit of the insertion portion, and the length of the insertion portion in the first direction is larger than the opening width between the lip portions of the stud. The upright portion stands up from a second end portion located on the side opposite to the first end portion of the insertion portion and faces the fixed plate portion. Reinforcement member. [2] The insertion portion is provided with a first notch portion at a corner portion adjacent to the slit. The reinforcement member of [1]. [3] A plurality of through holes are formed in the first region and the second region of the fixed plate portion along the second direction. The reinforcement member of [1] or [2]. [4] The upright portion is formed with second notch portions at both ends in the first direction, and includes a region where the length in the first direction gradually decreases from the base end portion toward the open end portion side in the second direction. The reinforcement member according to any one of [1] to [3]. [5] The width W of the second notch portion rk is the following formula:

[Modes for carrying out the invention]

[0012] Hereinafter, one embodiment of the reinforcing member, building wall structure, and building wall construction method of the present invention will be described with reference to the drawings.

[0013] Figure 1 is a schematic diagram illustrating one embodiment of a building wall structure to which the reinforcing member of the present invention is attached, and Figure 2 is a perspective view illustrating one embodiment of a stud to which the reinforcing member of the present invention is attached.

[0014] As illustrated in Figure 1, this building wall structure 100 has a pair of runners 1 (upper runner 1A and lower runner 1B) arranged spaced apart from each other in the vertical direction. The upper runner 1A and lower runner 1B have a roughly U-shaped cross-section with an open portion on the inside, with the open portion of the upper runner 1A facing downwards and the open portion of the lower runner 1B facing upwards.

[0015] As illustrated in Figure 2, the stud 2 is a lip channel steel (C-shaped steel). Specifically, the stud 2 comprises a web 21, a pair of flanges 22 extending from both ends of the web 21, and a pair of lip portions 23 extending inward (towards the opening C) from the flanges 22. The flanges 22 are approximately perpendicular to the web 21, and the lip portions 23 are approximately perpendicular to the flanges 22. The web 21 is wider than the flanges 22. The pair of lip portions 23 are spaced apart from each other, and an opening C is formed inside the stud 2, open through the space between the lip portions 23. Both ends of the stud 2 in the longitudinal direction are also open.

[0016] As illustrated in Figure 1, in this building wall structure 100, the studs 2 have their upper end 2A and lower end 2B inserted inside the runner 1. The studs 2 are positioned so that the opening C faces the longitudinal direction of the runner 1. That is, the outer surface of the flange 22 of the studs 2 is positioned parallel to the longitudinal direction of the runner 1. A facing material such as gypsum board (not shown) can be fixed to the outer surface of the flange 22 of the studs 2.

[0017] <First Embodiment> Figure 3 is a perspective view illustrating a first embodiment of the reinforcing member of the present invention. Figure 4 is a front view illustrating one embodiment of the building wall structure and building wall construction method of the present invention using the reinforcing member of the first embodiment. Figure 5 is a perspective view illustrating one embodiment of the building wall structure and building wall construction method of the present invention using the reinforcing member of the first embodiment. Figure 6 is an enlarged view of portion D in Figure 5. Note that Figures 1 and 2 may be used to refer to the runner and stud.

[0018] The building wall structure 100 of the present invention is A pair of runners 1 are arranged spaced apart from each other in the vertical direction. A stud 2 made of a lip-groove-shaped steel, comprising a web 21, a pair of flanges 22 extending from both ends of the web 21, and a pair of lip portions 23 extending inward from the flanges 22, Reinforcement member 3 Includes.

[0019] Furthermore, the construction method for building walls of the present invention is A stud 2 made of a lip-groove-shaped steel, comprising a web 21, a pair of flanges 22 extending from both ends of the web 21, and a pair of lip portions 23 extending inward from the flanges 22, Reinforcement member 3 Use materials that include the following:

[0020] The reinforcing member 3 is a member that is inserted into the opening C of the stud 2, which is made of lip-groove-shaped steel. The reinforcing member 3 comprises a fixing plate portion 31, an insertion portion 32, and an upright portion 33.

[0021] The fixing plate portion 31 is rectangular and flat, and includes a first region T1 and a second region T2 that are spaced apart from each other and facing each other. The first region T1 can abut against one outer surface of a pair of lip portions 23 of the stud 2, and the second region T2 can abut against the other outer surface of a pair of lip portions 23 of the stud 2. In this embodiment, the fixing plate portion 31 is a horizontally elongated rectangle, and the first region T1 and the second region T2 are located on one end 31A and the other end 31B of the fixing plate portion 31 in the longitudinal direction (first direction). In other words, the "first direction" in the present invention is the direction in which the first region T1 and the second region T2 of the fixing plate portion 31 face each other (direction of arrow X).

[0022] In this embodiment, the length W of the fixing plate portion 31 in the first direction (arrow X direction) r The width of the web is W 21 for stud 2. cw (Illustrated in Figure 2) The opening width W of the lip portion 23 is as follows: c (Figure 2) is greater than (W c <W r ≤W cw It is preferable that the fixed plate portion 31 has a length W in the first direction. r Within this range, deformation and twisting of the stud 2 can be suppressed, and the fixing plate portion 31 can be stably fixed to the stud 2.

[0023] Through holes 311 are formed in the first region T1 and the second region T2 of the fixing plate portion 31. In this embodiment, multiple through holes 311 (three in each direction) are provided at approximately equal intervals along the second direction (arrow Y direction) perpendicular to the first direction (arrow X direction) of the fixing plate portion 31. When the first region T1 and the second region T2 of the fixing plate portion 31 are in contact with the lip portion 23 of the stud 2, the fixing plate portion 31 can be fixed to the lip portion 23 of the stud 2 via the fixing device F by inserting a fastener F such as a screw or bolt through the through hole 311. In this case, the number of fasteners F is not particularly limited, and for example, from the viewpoint of fixing strength and stability, the fixing of the fixing plate portion 31 to the lip portion 23 by the fastener F can be done through at least one through hole 311 located at each end of the fixing plate portion 31 in the first direction (arrow X direction).

[0024] The insertion part 32 is flat and protrudes in the third direction (arrow Z direction) orthogonal to the fixing plate part 31 from one end 31C in the second direction (arrow Y direction) orthogonal to the first direction (arrow X direction) of the fixing plate part 31. At the first end 32A of the insertion part 32 located on the side connected to one end 31C in the second direction (arrow Y direction) of the fixing plate part 31, slit S that is long in a direction parallel to the first direction (arrow X direction) is formed at both ends in the first direction (arrow X direction).

[0025] Specifically, the insertion part 32 includes a support piece 321 and a connection part 322. The support piece 321 is substantially rectangular in shape and long in the first direction. The connection part 322 protrudes one step from near the center of the end on the fixing plate part 31 side of the support piece 321 and is connected to one end 31C in the second direction (arrow Y direction) of the fixing plate part 31. That is, the support piece 321 is formed wider in the first direction (arrow X direction) than the connection part 322. And between one end 31C in the second direction (arrow Y direction) of the fixing plate part 31 and the support piece 321, slit S is formed on both sides in the first direction (arrow X direction) of the connection part 322.

[0026] In this embodiment, the length of the support piece 321 in the first direction (arrow X direction) substantially coincides with the width of the inner surface of the opening C of the stud 2 [(width of the web 21) - (thickness of both flanges 22)]. Therefore, as illustrated in FIG. 5, when the reinforcing member 3 is inserted into the opening C of the stud 2, both end portions 321A, 321B of the support piece 321 in the first direction (arrow X direction) abut or are close to the inner surface of the opening C of the stud 2 (inner surfaces of the opposing flanges 22), and can support the inner surface from the inside. Note that in the reinforcing member of the present invention, the length of the support piece 321 in the first direction (arrow X direction) only needs to be designed to be longer than the opening width W of the lip portion 23 of the stud 2, and is not limited to the form illustrated in FIG. 5. c Furthermore, as described above, the length W in the first direction of the fixing plate part 31

[0027] is such that W r is, W c <W r ≦W cwAs illustrated in Figures 4 and 5, when the reinforcing member 3 is inserted into the opening C of the stud 2, and both ends 321A and 321B of the support piece 321 in the first direction (arrow X direction) come into contact with or approach the inner surface of the opening C of the stud 2 (the inner surfaces of the opposing flanges 22), the fixing plate portion 31 is positioned accordingly. In other words, in this embodiment, as the reinforcing member 3 is inserted into the opening C of the stud 2, the through holes 311 formed in the first region T1 and the second region T2 of the fixing plate portion 31 are positioned near the center in the width direction of the lip portion 23 of the stud 2. Therefore, by inserting the fixing device F through the through holes 311, the fixing plate portion 31 can be stably fixed to the lip portion 23 of the stud 2 with minimal construction error.

[0028] The protruding length of the insertion portion 32 (length in the third direction (arrow Z direction)) is preferably 1 / 5 to 2 / 3 of the length of the flange 22 of the stud 2, preferably 2 / 5 to 3 / 5, and more preferably about 1 / 2. As illustrated in Figure 5, when the protruding length of the insertion portion 32 (length in the third direction (arrow Z direction)) is within this range, and the reinforcing member 3 is inserted into the opening C of the stud 2, the second end 32B (upright portion 33, described later), which is located on the opposite side of the first end 32A of the insertion portion 32, is located near the center of the flange 22 of the stud 2. Therefore, even when a high load is applied to the flange 22, bending of the lip portion 23 (reduction of the distance between the lip portions 23) is suppressed. In other words, deformation and twisting of the stud 2 are suppressed.

[0029] On the other hand, for example, in a modified form of the reinforcing member 3 of this embodiment, if the protruding length of the insertion portion 32 (length in the third direction (arrow Z direction)) is approximately equal to the length of the flange 22 of the stud 2, then the second end portion 32B of the insertion portion 32 in the third direction (arrow Z direction) (upright portion 33, described later) will be close to or in contact with the web 21 of the stud 2. However, in this case, compared to the form of the reinforcing member 3 of the present invention (building wall structure and method for constructing a building wall) illustrated in Figure 5, the strength of the web 21 of the stud 2 is increased, making it difficult to suppress bending of the lip portion 23 when a high load is applied to the flange 22.

[0030] The slit S is designed so that the lip portion 23 of the stud 2 can be inserted into it. That is, the length and width of the slit S are not particularly limited and can be appropriately designed according to the protruding length and thickness of the lip portion 23 of the stud 2. In this embodiment, the length of the slit S (length in the first direction (arrow X direction)) is formed to be in the range of about 1 / 6 to 1 / 3 of the length of the support piece 321 in the first direction (arrow X direction). As illustrated in Figure 4, when the lip portion 23 of the stud 2 is inserted into the slit S of the reinforcing member 3 (before fixing with the fastener F), the reinforcing member 3 can be freely slid along the longitudinal direction (longitudinal direction (arrow P direction)) of the stud 2 through the slit S. Therefore, for example, the reinforcing member 3 can be positioned at the upper end 2A and lower end 2B of the stud 2, or at any other desired position on the stud 2. In other words, the reinforcing member 3 is easy to attach to the stud 2 and the fixing position can be easily adjusted.

[0031] On the first end 32A side of the support piece 321 adjacent to the slit S, a first notch R is provided at both corner portions 321C in the first direction (arrow X direction). The provision of the first notch R at the corner portion 321C of the support piece 321 widens the opening of the slit S on the first direction (arrow X direction) side, making it easier to insert the lip portion 23 of the stud 2 into the slit S. Furthermore, as illustrated in Figure 6, generally, the inner corner of the stud 2 formed by the flange 22 and the lip portion 23 is not a strict right angle, but may be curved or slightly thicker. Even in such configurations, the provision of the first notch R at the corner portion 321C of the support piece 321 means that when the lip portion 23 of the stud 2 is inserted into the slit S, the first notch R faces the inner corner of the stud 2, allowing both ends 321A and 321B of the support piece 321 of the reinforcing member 3 in the first direction to be brought close to the inner surface of the flange 22. Therefore, the reinforcing member 3 of this embodiment can suppress deformation and twisting of the stud 2, and is also easy to attach to the stud 2 and slide in the longitudinal direction of the stud 2, resulting in excellent workability.

[0032] The upright portion 33 rises from the second end 32B, which is located opposite the first end 32A of the insertion portion 32, and faces the fixing plate portion 31. The upright portion 33 is substantially parallel to the fixing plate portion 31. The height of the upright portion 33 is not particularly limited, but is preferably in the range of 1 / 8 to 1 / 3 of the height of the fixing plate portion 31, and more preferably 1 / 5 to 1 / 3. More specifically, the height H of the upright portion 33 r The opening width W of the lip portion 23 c (Illustrated in Figure 2) The following conditions must be met (H r ≤W c ) is preferable. Height H of the upright portion 33 r Within this range, deformation and twisting of stud 2 can be suppressed. Also, the height H of the upright portion 33 r Within this range, even after the studs 2 have been installed in the runner 1, the reinforcing member 3 can be easily inserted into the opening C of the stud 2, and the attachment and fixing position of the reinforcing member 3 to the stud 2 can be easily adjusted.

[0033] As described above, the reinforcing member 3 of the present invention can suppress deformation and twisting of the stud 2, and the attachment and fixing position to the stud 2 can be easily adjusted. Furthermore, the building wall structure 100 of the present invention can suppress deformation and twisting of the stud 2.

[0034] Furthermore, the construction method for the building wall of the present invention includes the steps of inserting the lip portion 23 of the stud 2 into the slit S of the insertion portion 32 of the reinforcing member 3, and arranging the insertion portion 32 and the upright portion 33 of the reinforcing member 3 within the opening C of the stud 2, The process involves fixing the first region T1 of the fixing plate portion 31 of the reinforcing member 3 to one outer surface of the pair of lip portions 23 of the stud 2, and fixing the second region T2 to the other outer surface of the pair of lip portions 23 of the stud 2, This includes the following. According to the construction method of the present invention, deformation and twisting of the stud 2 can be suppressed, and the attachment and fixing position to the stud 2 can be easily adjusted.

[0035] <Second Embodiment> Figure 7 is a perspective view illustrating a second embodiment of the reinforcing member 3 of the present invention. Parts common to the first embodiment are denoted by the same reference numerals, and their descriptions are omitted below.

[0036] In the reinforcing member 3 of this embodiment, the upright portion 33 has second notches 331 formed at both ends in the first direction, and includes a region in which the length in the first direction (arrow X direction) gradually decreases from the base end (second end 32B of the insertion portion 32) toward the open end 33A in the second direction (arrow Y direction). Specifically, the length of the upright portion 33 gradually decreases in the first direction (arrow X direction) as it rises from the second end 32B of the insertion portion 32 toward the open end 33A in the second direction (arrow Y direction).

[0037] Width W of the second notch 331 of the upright portion 33 rk The length in the first direction (arrow X direction) is not particularly limited, but it is preferable that it satisfies the following formula.

number

[0038] Width W of the second notch 331 rk By satisfying the above equation (1), deformation and twisting of the stud 2 can be suppressed, and even after the stud 2 has been installed in the runner 1, the reinforcing member 3 can be easily inserted and attached to the opening C of the stud 2.

[0039] Figure 8 is a schematic diagram showing an example of how the reinforcing member 3 of the second embodiment is attached to the stud 2.

[0040] As illustrated in Figure 8, in the second embodiment, the reinforcing member 3 has a second notch 331 formed at both ends of the upright portion 33 in the first direction (arrow X direction). For example, the slit S of the reinforcing member 3 can be brought close to the lip portion 23 of the stud 2 from diagonally above, and the lip portion 23 can be inserted into the slit S. In this case, the reinforcing member 3 can be inserted so that the second notch 331 of the upright portion 33 faces the inner surface of the flange 22 of the stud 2. Therefore, compared to the first embodiment, the reinforcing member 3 can be inserted into the opening C of the stud 2 even more easily. Accordingly, in the second embodiment, the reinforcing member 3 can be attached to the stud 2 even after the stud 2 has been installed in the runner 1.

[0041] Figure 9 is a perspective view illustrating one embodiment of the building wall structure and building wall construction method of the present invention using the reinforcing member 3 of the second embodiment.

[0042] In this embodiment of the building wall structure and building wall construction method, deformation and twisting of the stud 2 can be suppressed, and the attachment and fixing position to the stud 2 can be easily adjusted.
