Description

  TECHNICAL FIELD The present invention relates to a reinforcing metal fitting suitably used for a building, particularly a wooden frame structure. More specifically, the present invention not only pulls in order to prevent a column from being pulled out but also actively resists an acting horizontal force. The present invention relates to a reinforcing metal fitting for construction that makes it possible.

  In order to maintain the strength of the frame against the horizontal force, a bearing wall is formed with a brace or a structural plywood. The brace is fixed by using a hardware considering compression and tension. The structural plywood is fixed with nails to the outer surface of a vertical member such as a pillar or a horizontal member such as a base. By obtaining the bearing wall in this way, the strength of the housing is increased.

  However, when the vertical member and the horizontal member are not tightly coupled according to the stress, the vertical member is pulled out or the mortise end is broken. Even if the structural plywood is nailed with a nail, if the horizontal force acts and deforms, the nail will come off and cannot resist the load.

  For this reason, a reinforcing hardware that exhibits a pulling force like a hole-down hardware is required.

  As such a reinforcing metal for pulling, for example, the following patent document 1 has been described as a prior art (see paragraph [0004] of FIG. 6 and FIG. 6). In other words, the side of the column base is provided with a metal part fixed at a position distant from the upper surface of the base, and a lower part of the metal part is provided with a portion projecting horizontally, and a bolt extending from the foundation is provided at this part. The upper end is fixed.

  However, this only pulls the column base part to the base and has an effect of preventing the column from coming off, but does not actively resist the load applied by the horizontal force. Due to the above-mentioned fixing structure that fixes the metal fitting fixed to the side of the pillar to the upper end of the bolt extending from the foundation at a position spaced from the upper surface of the foundation, a load more than that supported by the joint or joint hardware is applied. In such a case, the vertical member is allowed to swing.

  With regard to such points, Patent Document 1 points out the problem that the load is biased when a horizontal force is applied, and the joint between the column and the base becomes a weak point in strength. In order to prevent this, an invention is disclosed in which a reinforcing bar (anchor bolt) is inserted into the central axis of a column and fixed with an adhesive.

Japanese Patent Laid-Open No. 9-100576

  However, in the invention of Patent Document 1, the force of pulling down like a hole-down hardware cannot be exhibited only by holding the column base at its center. In addition, when a horizontal force is applied, the force that positively resists this load is supported only by the reinforcing bar portion for joining, and it is considered that it is embedded in a column or the like, so that sufficient proof stress cannot be obtained. In addition, since the joining rebar is passed through the center of the column, there is a problem that it cannot be used at a place where the column and the beam are joined with the joint hardware because they interfere with each other.

  Accordingly, the main object of the present invention is to be able to resist both pulling out and horizontal force and to improve the strength comprehensively by making use of the bearing wall.

  Means therefor are a reinforcing metal fitting for construction that reinforces the joining state of the vertical member and the horizontal member constituting the frame of the building, the fixing fitting fixed to the vertical member, and the fixing fixed to the horizontal member. While the metal fittings are provided, these fixed metal fittings are reinforcing metal fittings for construction connected by a force-bearing member having at least a tensile strength.

  In this configuration, the fixing member fixed to the vertical member and the horizontal member joined to each other secures the position on the vertical member or the horizontal member, and when the horizontal force is applied, the strength member for connecting the fixing member is provided. At least resists tension. In particular, if the load bearing member is fixed so as to extend diagonally, it acts like a brace and more actively supports the load acting on the horizontal force.

  According to the present invention, since the fixing brackets fixed to the vertical member and the horizontal member are connected by the strength members, the pulling of course, the horizontal force acts and the support is supported by the joint or the joint hardware. Even when the load is applied, a reinforcing structure capable of resisting the load is obtained. And, by fixing the building reinforcement hardware in relation to the bearing wall, it is possible to create a rigid system for the entire building by utilizing the rigidity of the bearing wall, and to improve the overall strength of the building be able to.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view of a wooden frame structure 11 as a building, and FIG. 2 is a front view of the wooden frame structure 11 and a side view of FIG. As shown in these drawings, a vertical member 12 such as a column and a horizontal member 13 such as a beam constituting the frame are referred to as a plurality of building reinforcing hardwares 21 (hereinafter referred to as “reinforcing hardware”) that reinforce their joining state. ).

  The reinforcing hardware 21 includes a fixing bracket 22 that is fixed to the side surface of the vertical member 12, a fixing bracket 23 that is fixed to the upper surface or the lower surface of the horizontal member 13, and a load-bearing member 24 that connects the fixing brackets 22 and 23. Have

  The plurality of reinforcing hardwares 21 shown in FIGS. 1 to 3 show an example in which a specific configuration is changed according to a place to be attached.

  One of the plural types of reinforcement hardware 21 (reinforcement hardware of portion A in FIG. 1) is shown in FIG. 4, FIG. 5, and FIG. The configuration of the reinforcing hardware 21 will be described using these.

  The auxiliary hardware 21 obliquely connects a portion forming a right angle of a joint portion between the column base portion of the tube column 12a as the vertical member 12 and the beam member 13a as the horizontal member 13 supporting the tube column 12a. It is configured, and is used for fixing from above the load bearing wall constituting panel 51 fitted in a rectangular space surrounded by the vertical member 12 and the horizontal member 13.

  Both the fixing bracket 22 fixed to the vertical member 12 and the fixing bracket 23 fixed to the horizontal member 13 are formed in a U-shaped cross section, and a rotation shaft capable of relative rotation between two opposing pieces facing each other. 25 is provided.

  In the fixing bracket 22 fixed to the vertical member 12, the connecting piece 27 that connects the two facing pieces 26 is a fixing surface that comes into surface contact with the fixing portion, and a plurality of fixing holes 27 a are formed in the connecting piece 27. Has been. The fixing hole 27a is a part through which the fastener 28 for fixing is inserted. For the fastener 28, a well-known bolt and nut may be used, but as shown in FIG. 6, a fastening shaft member 28a and a nut 28b in which male screws are formed at both ends of the deformed reinforcing bar may be used. The length of the fastener 28 is set to a length that can be fixed by the nut 28b on the opposite surface of the vertical member 12 (see FIG. 5).

  On the other hand, in the fixing bracket 23 fixed to the horizontal member 13, the connecting piece 27 is provided with a fixing hole 27 a through which the fastener 28 is passed, and a universal washer that allows the angle of the fixing bracket 23 to the horizontal member 13 to be changed. Means 31 are provided.

  The universal washer means 31 includes a spherical washer 32 having a hemispherical spherical surface provided on the inner and outer surfaces of the connecting piece 27 and an annular sliding ring 33 that slides on the spherical surface of the spherical washer 32. Is done. The spherical washer 32 is configured by press molding so that a metal plate sticks out to one side. A through hole (not shown) is formed at the top of the spherical washer 32. The through hole is formed by a loose hole larger than the size through which the fastener 28 is passed. Such a loose hole is also applied to the fixing hole 27a of the connecting piece 27 that holds the spherical washer 32.

  One end of the fastener 28 is held on the sliding ring 33 provided on the inner side of the connecting piece 27, and a known washer 34 is held on the lower side of the sliding ring 33 provided on the outer side of the connecting piece 27. . As a result, the connecting piece 27 does not come into direct surface contact with the horizontal member 13, but indirectly comes into surface contact with the washer 34.

  For the fastener 28, a well-known bolt and nut can be used as described above, but the fastening shaft 28a and the nut 28b may be used. In this case, in order to hold one end of the fastener 28, it is preferable to secure the strength by using a lock nut as shown by a broken line in FIG. The length of the fastener 28 is set to a length that can be fixed by the nut 28b on the opposite surface of the horizontal member 13 (see FIG. 5).

  When the universal washer means 31 is provided, the angle formed by the fixing bracket 23 and the fastener 28 can be changed in a state where the universal washer means 31 is integrated with the connecting piece 27 by the fastener 28.

  The load bearing member 24 is formed of a rod-shaped body made of steel so as to have at least tensile strength, and both ends are held by the rotary shaft 25. The holding may be performed by screwing the nut 35 into the male screw at the end passing through the rotating shaft. An appropriate existing member can be used as the load bearing member, but as shown in FIG. 6, a member in which male threads are formed at both ends of the deformed reinforcing bar may be used.

  The load bearing member 24 and the rotating shaft 25 that holds the end of the load bearing member 24 are angle changing means 36 that can change the angle of the load bearing member 24 with respect to the fixtures 22 and 23.

  Since the angle changing means 36 and the universal washer means 31 are provided, when the reinforcement member 21 is mounted as shown in FIG. The angle of the fixture 23 to be fixed changes at two locations.

  Here, the load-bearing wall constituting panel 51 will be described. The bearing wall constituting panel 51 is a panel for constituting the bearing wall 15 by being attached to at least four corners of the space surrounded by the vertical member 12 and the horizontal member 13, and the vertical member 12 and the horizontal member 13 which are joined to each other. The surface material 52 is brought into surface contact with the inner surface of the vertical material 12 and the horizontal material 13 in the space surrounded by the surface, and is fixed to both the front and back surfaces of the surface material 52 and is in surface contact with the inner surface of the vertical material 12 and the horizontal material 13. The holding frame material 53 is provided.

  The face material 52 is composed of three face material carriers 52a arranged so as to be aligned in the height direction of the space, and the width of the vertical material 12 and the horizontal material 13 is between these face material carriers 52a. An intervening material 54 having the same width is interposed. Insertion grooves 54 a into which corresponding portions of the face material carrier 52 a are fitted are formed on both upper and lower surfaces of the interposing material 54.

  Further, sandwiching vertical bars 55 that are fixed to both the front and back surfaces of the face material carrier 52a and extend in the vertical direction are fixed at intermediate positions in the width direction of the face material carrier 52. The sandwiching vertical beam member 55 and the sandwiching frame member 53 are set so that the outer surfaces thereof are flush with the surfaces of the vertical member 12 and the horizontal member 13.

  The load bearing wall constituting panel 51 is fixed using nails. In addition, although it can be configured as a single panel in advance, during the renovation and reinforcement work, three members divided for each face material carrier 52a in the interposition material 54 portion, and the sandwiching material 53 It is possible to configure the bearing wall 15 by separating them and fitting them while assembling at the site.

  Since the bearing wall constituting panel 51 is fixed from above, the width of the connecting piece 27 of the fixing brackets 22 and 23 in the reinforcing hardware 21 is set to be equal to the width of the holding frame member 53.

  The reinforcing hardware 21 configured as described above is attached at an appropriate position in the casing in consideration of the load applied to the casing. It can be used not only for new construction but also for renovation or reinforcement work.

  The attachment is preferably performed by fixing one of the fixing brackets 22 and 23 to the vertical member 12 or the horizontal member 13 that is continuous with the load bearing wall 15 in the housing. The fixing position is preferably close to the load-bearing wall 15 and is appropriately fixed to a portion capable of supporting and dispersing the load.

  4, 5, and 6, the load bearing wall constituting panel 51 is fixed to a portion constituting the bearing wall 15, and then the through hole 16 formed in the vertical member 12, the horizontal member 13, and the bearing wall 15. The fasteners 28 of the fixing brackets 22 and 23 in the reinforcing hardware 21 are inserted and tightened (see FIG. 5). This coupling is performed at a position away from the joining portion of the vertical member 12 and the horizontal member 13 along the longitudinal direction of each member.

  At this time, since the fixing bracket 23 fixed to the horizontal member 13 is provided with the universal washer means 31 and the angle changing means 36, the fixing bracket 23 can be fixed in a state in which it is directed in the longitudinal direction of the load bearing member 24. Moreover, since the universal washer means 31 is fastened to the horizontal member 13 by tightening the nut 28a, the fixed state can be maintained strongly.

  For this reason, in addition to preventing the pull-out member 24 from pulling out, it also acts as a brace, which can strongly counter the tensile load applied when a horizontal force is applied.

  In addition, the two fixing brackets 22 and 23 are respectively fixed to the vertical member 12 or the horizontal member 13, whereby the positions of both ends of the load-bearing member 24 are strongly restricted, and the positional relationship between the vertical member 12 and the horizontal member 13 is also determined. Retained. For this reason, even if a tensile load is applied to the load bearing member 24, the vertical member 12 and the horizontal member can be actively prevented from opening.

  In addition, since the fixing bracket 23 is fixed at a position away from the joint between the vertical member 12 and the horizontal member 13, even when the vertical member 12 and the horizontal member 13 are joined to each other at the joint, the vulnerability is caused. Can be maintained and the bonding force can be maintained. When the vertical member 12 and the horizontal member 13 are joined with a joint metal, interference with the joint metal can be prevented, and both strong joining with the joint metal and reliable reinforcement with the reinforcement metal can be achieved.

  Since the reinforcing hardware 21 is fixed to the vertical member 12 and the horizontal member 13 constituting the bearing wall 15, the load is distributed and the rigidity of the bearing wall 15 is given to other parts to provide the bearing wall. With the arrangement of 15 and the reinforcing hardware 21, systemization can be achieved and the strength of the entire frame can be increased. As a result, it is possible to obtain a long-term excellent house with high earthquake resistance.

  For this reason, the bearing wall 15 may be configured by the brace 56 as shown in FIG. 7 having a lower strength than the above-described high-rigidity bearing wall constituting panel. Moreover, even if it joins the vertical material 12 and the horizontal material 13 also by a joint, it becomes possible to obtain the intensity | strength as the whole housing.

  In the case where the reinforcing hardware 21 is not fixed from above the load bearing wall 15, it may be coupled to the center in the width direction of the vertical member 12 or horizontal member 13. The width of the piece 27 can be increased.

  In order to resist not only the tensile load but also the compressive load, the nut 35 may be fixed so as to sandwich the rotating shaft 25 with respect to the end of the load bearing member 24.

  Hereinafter, another example of the reinforcing hardware 21 will be described. In this description, parts that are the same as or equivalent to the previous configuration are given the same reference numerals, and detailed descriptions thereof are omitted.

  The reinforcing hardware 21 shown in FIG. 8 is an example provided with four fixing brackets 22 and 23, and can be suitably used when the lower part and the upper part of the vertical member 12 are fixed to the horizontal member 13 together. (See part B in FIG. 1).

  That is, two fixing brackets 22 fixed to the vertical member 12, two load bearing members 24 each having one end held by these rotating shafts 25, and the other ends of these load bearing members 24 are connected to the rotating shaft. 25, two fixing brackets 23 to be fixed to 25, and a fastener 28 for connecting the universal washer means 31 of these fixing brackets 23 to each other.

  In the reinforcing hardware 21 configured as described above, the head can be reinforced at the same time as the legs of the vertical member 12, and the rigidity of the load bearing wall 15 is increased to the vertical member 12 positioned above the same as the portion B in FIG. Is also suitable to act.

  9 is an example in which the universal washer means 31 is omitted. Although the universal washer 31 is not provided, the angle changing means 36 is provided, so that even if the position of the through hole 16 formed in the vertical member 12 or the horizontal member 13 is shifted, it can be dealt with. In addition, although the fixing position of the fixing bracket 23 fixed to the horizontal member 13 is close to the vertical member 12, for example, when a joining metal is not used for joining the vertical member 12 and the horizontal member 13, the portion C is shown in FIG. When used suitably, a yield strength capable of resisting at least tension is obtained.

  In this case as well, when the four fixing brackets are used as in the reinforcing hardware 21 shown in FIG. 8, the vertical members 12 positioned above and below the horizontal member 13 are horizontally arranged as shown in the D part of FIG. The integrity of the vertical members 12 can be enhanced while being integrated with the member 13, and the proof stress against a tensile load or a compressive load can be increased.

  The reinforcing hardware 21 shown in FIG. 10A is an example in which the load-bearing member 24 is formed of an elongated plate material instead of a rod-shaped body. As shown in FIG. 10B, the two load bearing members 24 made of a plate material are provided in parallel on the rotating shaft 25 via spacers 37.

  The reinforcement hardware 21 exhibits the same effects as the reinforcement hardware 21 provided with the load-bearing member 24 made of the deformed reinforcing bar. In particular, since the load bearing member 24 is made of a plate material and both ends are rotatably held by the rotating shaft 25, the load bearing member 24 has a load bearing force against a tensile load and a compressive load without separately fixing a nut.

  The reinforcing metal piece 21 shown in FIG. 11 is an example in which the universal washer means 31 is omitted from the reinforcing metal piece 21 shown in FIG. The same effect as the reinforcing hardware 21 of FIG. 9 is obtained.

  The reinforcement hardware 21 shown in FIG. 12A is an example in which the load bearing member 24 is formed of a loop-shaped wire instead of a rod-shaped body or a plate-shaped body. That is, the load bearing member 24 made of a wire is hung on the rotating shaft 25 of each of the fixing brackets 22 and 23. When the thickness of the load bearing member 24 is smaller than the width of the rotary shaft 25, spacers 37 are held on both sides of the load bearing member 24 as shown in FIG.

  In this reinforcement metal 21, the strength member 24 strongly opposes the tensile load, and the same effect as the reinforcement hardware provided with the strength member 24 made of the deformed reinforcing bar is exhibited. Further, since the load bearing member 24 is a wire, it can flexibly cope with a positional shift of the through holes 16 of the vertical member 12 and the horizontal member 13.

  13 is an example in which the universal washer means 31 is omitted from the reinforcement hardware 21 of FIG. The same effect as the reinforcing hardware 21 of FIG. 12 is obtained.

  The reinforcing hardware 21 shown in FIG. 14 is an example in which the fixtures 22 and 23 are formed in a regular triangular shape in front view. That is, it has a fixed piece 41 that contacts the vertical member 12 or the horizontal member 13, a connecting piece 42 that connects one end of the load bearing member 24, and a connecting piece 43 that connects the fixed piece 41 and the connecting piece 42. The width and length of each piece 41, 42, 43 are appropriately set according to the size of the place to be attached.

  A reinforcing piece 44 is provided at a joint portion between the pieces 41, 42, and 43 for reinforcement. FIG. 15A shows an example in which the reinforcing pieces 44 are mounted so as to block both sides in the width direction of the pieces 41, 42, and 43. FIG. 15B shows that the pieces 41, 42, and 43 are bridged. This is an example in which a reinforcing piece 44 is mounted.

  The fixing piece 41 is formed with a fixing hole 41 a through which the fastener 28 is inserted, and the coupling piece 42 is formed with a through hole 42 a through which the strength member 24 is passed. The through hole 42 a is set to be larger than the thickness of the load bearing member 24. This is because the angle changing means 36 is provided.

  The angle changing means 36 in this example includes a spherical washer 45 having a hemispherical spherical surface provided on the inner surface of the coupling piece 42 and an annular sliding ring 46 that slides on the spherical surface of the spherical washer 45. The The spherical washer 45 and the sliding ring 46 have the same structure as those of the universal washer means 31, and a through hole (not shown) is formed at the top of the spherical washer 45. One end of the fastener 24 is held on the sliding ring 46. For the fastener 24, a well-known bolt can be used in the same manner as described above, but a rod-like body made of a deformed reinforcing bar may be used.

  In order to cope with a compressive load, it is preferable that a spherical washer 45 and a sliding ring 46 are provided on the outer surface of the coupling piece 42.

  In the reinforcing hardware 21 having such a configuration, the same effect as that of the above-described reinforcing hardware 21 is achieved, and the fixing bracket 22 fixed to the vertical member 12 and the fixing bracket 23 fixed to the horizontal member 13 are the same. Since it can be used, it is easy to use and the manufacturing cost can be reduced.

  In the illustrated example, since the fixing positions of the fixing brackets 22 and 23 are equidistant from the vertical member 12 and the horizontal member 13, the load bearing member 24 forms an angle of 45 degrees, but includes the angle changing means 36. Therefore, if the positions of the fixing brackets 22 and 23 are changed, the angle of the load bearing member 24 can be changed following the change, and can be flexibly handled according to the fixing mode.

  In addition, since the fixing brackets 22 and 23 are triangular in front view, the strength is high and the amount of material used can be suppressed.

  Although not shown, the fixing brackets 22 and 23 may be fixed to a shallowly carved portion.

  FIG. 16 shows another example of the reinforcing hardware 21 shown in FIG. This includes four fixing brackets 22, 23, two sets of two fixing brackets 22, 23 connected by one load bearing member 24, and fixing brackets 23 fixed to the horizontal member 13. This is an example in which the fasteners are connected and configured.

  In the reinforcing hardware 21 configured in this way, the head portion as well as the leg portion of the vertical member 12 can be reinforced at the same time, so that the rigidity of the load bearing wall 15 is positioned above the vertical member 12 as shown in B portion of FIG. It is also suitable for making it act.

  Furthermore, as shown in FIG. 17, it can also be set as the reinforcement metal object 21 which can be fixed so that the junction part of the vertical material 12 and the horizontal material 13 may be surrounded.

  FIG. 18 shows another example of the reinforcing hardware 21 using equilateral triangle-shaped fixing brackets 22 and 23, and is an example in which a core pin 28d having a cylindrical shape and having female threads 28c at both ends is used as a fastener. . A bolt 28e is screwed into the female screw 28c of the core pin 28d, and thereby the fixed state to the fixing brackets 22, 23, the vertical member 12, and the horizontal member 13 is maintained.

  Even with this configuration, the same effect as that of the reinforcing hardware 21 shown in FIG. 14 can be obtained. However, since the core pin 28d as described above is used, the hole 28f provided in the intermediate portion in the longitudinal direction of the core pin 28d is formed by another member. The aspect which comprises a housing | casing can be expanded.

  The fixing brackets 22 and 23 shown in FIG. 19 show an example in which a single metal plate is bent. FIG. 19A is a perspective view, and FIG. 19B is a cross-sectional view. That is, a metal plate having an appropriate width is bent so that the middle part in the longitudinal direction forms a regular triangle shape in front view, and is pressed so that both end parts overlap. The extending portion 47 extending flush with the fixing piece 41 is provided, and fixing holes 41 a and 47 a through which the fasteners 28 are inserted are formed in the extending portion 47 and the fixing piece 41. In addition, a through hole 42a is formed in the coupling piece 42 in the same manner as described above.

  The fixing brackets 22 and 23 shown in FIG. 20 are examples in which the angle changing means 36 is omitted from the reinforcing hardware 21 of FIG. 14, and between the fixing piece 41, the coupling piece 42, and the connecting piece 43 as shown in FIG. 19. This is an example in which the angle is not a regular triangle with an angle of 60 degrees, but a right-angled triangle in front view. In this case, the two pieces sandwiching the right angle both function as the coupling piece 42 depending on the mounting direction.

  That is, the fixing piece 41 and the extending piece 47 continuous thereto have fixing holes 41a and 47a through which the fasteners 28 are inserted, and two pieces (the coupling piece 42 or the connecting piece 43) that form a right angle are provided. The through holes 41 a and 42 a that pass through the end portions of the load bearing member 24 are provided. Of the connecting pieces 42 or the connecting pieces 43, the pieces facing each other between the fixing member 22 of the vertical member 12 and the fixing member 23 of the horizontal member 13 are combined when fixed to the vertical member 12 or the horizontal member 13. It becomes the piece 42, and another piece becomes a connection piece. When the directions of the fixing brackets 22 and 23 are changed, these are reversed.

  In the reinforcing hardware 21 configured as described above, the opposing coupling pieces 42 are fixed so as to face each other in parallel, and the strength member 24 is fixed so as to be inclined at an angle of 30 degrees or 60 degrees. The 20, the load bearing member 24 functions as an oblique member at an angle of 30 degrees.

  According to this configuration, the same effect as that of the reinforcing hardware 21 of FIG. 14 can be achieved, and the angle changing means 36 is unnecessary, so that the cost can be reduced.

  FIG. 21 shows the reinforcing hardware 21 configured in a right-angled triangular shape in the same manner as the fixing brackets 22 and 23 shown in FIG. 20, but the two fixing pieces 41 are opened by protruding at both ends in the longitudinal direction. It is an example configured in a triangular shape.

  In any of the above-described reinforcement hardware 21, although not shown, it is preferable to provide appropriate reinforcement pieces or form ribs so as to ensure strength.

  22 shows an example of a fixing bracket formed in a substantially triangular pyramid shape, FIG. 22 (a) is a plan view, FIG. 22 (b) is a bottom view, FIG. 22 (c) is a front view, and FIG. FIG. 23 is a partial cross-sectional front view of the state of use. That is, it is a shape in which four corners of the regular triangular pyramid are cut out, and the four surfaces are coupled to one end portion of the load bearing member 24 to the fixing piece 41 whose surface is in contact with the vertical member 12 or the horizontal member 13. It is the structure which becomes both the piece 42 and the connection piece 43 which connects these. A through hole 48 is formed in each piece, and the fastener 28 and the strength member 24 similar to the above are connected. Each through-hole 48 holds a nut 28b or the like in advance as necessary. In the example of FIG. 23, the one provided with the angle changing means 36 is shown, but this may be omitted.

  In the auxiliary hardware 21 using the fixing brackets 22 and 23 having such a configuration, the same function and effect as described above can be achieved, and there are three surfaces for connecting one end of the load bearing member 24. By providing such angle changing means 36, the direction of the load bearing member 24 can be directed to any direction of 360 degrees, and the application range can be expanded. Moreover, since it is a triangular pyramid shape, the strength of the fixing brackets 22 and 23 themselves is high, and for example, the reinforcing piece 44 can be omitted.

  Further, as shown in FIG. 24, if a plurality of corner portions of the fixing brackets 22 and 23 are closed and a through hole 49 a through which a bolt or the like is inserted is formed in the closing piece 49, the application range and application are further expanded. be able to. 24A is a bottom view and FIG. 24B is a cross-sectional view.
