Description

  The present invention relates to a roof plate mounting bracket for fixing a roof plate on a base material such as H steel, and more particularly to a roof plate mounting bracket capable of obtaining high strength.

  The roof plate mounting bracket is used while being fixed to the base material. However, fixing the base plate by welding is complicated and not easy to work because of work at a high place.

  For this reason, the roof-plate attachment bracket like the following patent documents 1 and 2 which does not require welding for fixation with respect to a base material has been proposed.

  These roof plate mounting brackets are composed of a base member that is sandwiched and fixed to a base material, and a bracket main body that is erected on the base member. The base member has a flat upper surface, and a mounting plate at the lower end of the metal fitting body is fixed to the flat portion.

  The metal fitting body has a vertically long plate shape, and is configured by joining two joining members having the same shape having a receiving plate at the upper end back to back. The surface direction of the two joining members is the same as the gradient direction of the roof, and a hanger for locking the roof plate is held at the upper end portion between the joining members.

  In the roof plate mounting bracket having such a configuration, since the two joining members are joined together, sufficient strength can be obtained.

  However, since the separate joining members are fixed to the base member at the time of assembly, workability is not good.

  As a countermeasure for this, it is conceivable to configure the metal fitting body with a single member. In the following Patent Document 3, a non-welded type is not directly welded and fixed to a base material, but a roof plate formed by bending brackets extending in alternate directions at both ends of the roof of the bracket body in the gradient direction. A mounting bracket is disclosed. At the upper end of the metal fitting main body, there are two support pieces formed by alternately extending in the direction of the gradient of the roof to receive the roof plate.

  The bracket is for increasing the strength against bending and twisting of the metal fitting body, and is formed in a trapezoidal shape that becomes wider at the lower side below the intermediate portion in the height direction of the metal fitting body. The bracket extends in the opposite direction to the support plate formed nearby. In addition, a mounting seat for fixing to the base is formed outwardly at the lower end of the bracket.

  According to the roof plate mounting bracket of Patent Document 3, the mounting stability of the bracket body can be obtained, but the load applied from the mounted roof plate must be supported by a single plate-like portion at the top of the bracket body. Don't be.

  In addition, since the bracket has a trapezoidal shape extending toward the lower side and the protruding direction of the bracket is close and opposite to the support piece, the roof plate mounting bracket has a bulky shape. For this reason, there is a difficulty in taking a place for storage and transportation, handling is poor, and the efficiency of construction work is not good. Moreover, since a large area is required for fixing, it is good to construct a metal fitting that is fixed directly to the base material without welding, but it is assembled on the base member as in Patent Documents 1 and 2. In the case of the metal fitting configured, the base member must be large, and the configuration as in Patent Document 3 is difficult to adopt.

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 roof plate mounting bracket 11 (hereinafter referred to as “metal bracket”), and this bracket 11 is used by attaching a suspension 12 for locking a roof plate (not shown) to the upper end portion. .

  In addition to the so-called square goby type as shown in FIG. 1, the hanger 12 may be a round goby type as shown by phantom lines, and the hanger 12 can have various shapes. The hanging element 12 shown in FIG. 1 has a surface in which a fixing portion 12a used for fixing extends vertically, and is inserted into a square bolt 13 that is inserted laterally into a through hole 12b formed in the fixing portion 12a. And a washer 14 and a spring washer 15 and a nut 16 that is screwed to the root bolt 13. An auxiliary member 17 is attached to the hanging member 12. The auxiliary member 17 is substantially L-shaped in a front view having a receiving portion 17a that receives a roof plate to be attached. The auxiliary member 17 may have a plate shape without the receiving portion 17a or may be omitted.

  As shown in FIG. 2, the metal fitting 11 is fixed to the H steel 18 as a base material, and is fixed to the base member 31 fixed to the H steel 18 and the base member 31. A metal fitting body 51 is provided.

  As shown in FIG. 3, the base member 31 includes an upper metal member 32 and a lower metal member 33.

  The upper metal fitting 32 has a horizontal U-shape when viewed from the front, has a flat plate portion 32a having a rectangular shape in plan view and longer than the width of the H steel 18 on the upper surface, and has hanging piece portions 32b on both side edges of the flat plate portion 32a. . The height of the hanging piece 32b is a height at which the metal fitting body 51 can be fixed and a necessary strength can be obtained. Of the suspended piece 32b, an edge 19a corresponding to the lower side in the gradient direction of the roof in the flange 19 on the H steel 18 at one end portion in the longitudinal direction, specifically, the portion corresponding to the lower side in the gradient direction of the roof. A hook-shaped locking portion 34 is formed to be locked to the hook (see FIG. 2). The locking portion 34 has an inverted L-shape when viewed from the side, and is locked by moving the flange 19 of the H steel 18 from the outside to the inside.

  Two through holes 35 for fixing the metal fitting body 51 are formed in the middle portion of the flat plate portion 32a in the longitudinal direction.

  A long hole 36 for attaching the lower metal fitting 33 is formed at the other end portion in the longitudinal direction of the flat plate portion 32a, specifically, at a portion corresponding to the upper side in the gradient direction of the roof. The long hole 36 extends in the longitudinal direction of the flat plate portion 32a in the middle of the flat plate portion 32a in the width direction. A bulging rib 37 and a bending rib 38 for holding the shape of the other end portion of the upper metal fitting 32 are formed at portions facing both ends in the longitudinal direction of the long hole 36. The bulging rib 37 protrudes upward at a position between the elongated hole 36 and the through hole 35 in a shape extending in the width direction of the flat plate portion 32a. The bending rib 38 is formed by folding the other end edge of the flat plate portion 32a upward.

  The lower metal fitting 33 has a U-shape in a front view like the upper metal fitting 32, has a flat plate portion 33a having a predetermined width on the upper surface, has hanging piece portions 33b on both side edges of the flat plate portion 33a, and is located inside the upper metal fitting 32. The size corresponds to the fitting. The length in the direction corresponding to the longitudinal direction of the upper metal fitting 32 is not more than half of the length of the upper metal fitting 32, and the roof gradient direction in the flange 19 of the H steel 18 is provided at the other end corresponding to the upper side of the roof gradient direction. A hook-shaped locking portion 39 that locks to the edge 19b corresponding to the lower side is formed (see FIG. 2). The locking portion 39 is also L-shaped in a side view, and is locked by moving the flange 19 of the H steel 18 from the outside to the inside.

  The height of the lower metal part 33 including the locking part 39 is a height at which the flat plate part 32a of the upper metal part 32 becomes horizontal or substantially horizontal when stored under the upper metal part 32.

  At the center of the flat plate portion 33 a of the lower metal fitting 33, a bolt 40 penetrating the long hole 36 of the upper metal fitting 32 is erected. A washer 41 and a spring washer 42 are inserted into the bolt 40, and a nut 43 is screwed together.

  A bulging rib 44 that protrudes downward is formed at a position where the bolt 40 in the flat plate portion 33a is sandwiched in the gradient direction of the roof.

  FIG. 4 shows a cross section in a state where the base member 31 is fixed to the flange 19 of the H steel 18. When the base member 31 is fixed, the locking portion 34 of the upper metal fitting 32 and the locking portion 39 of the lower metal fitting 33 are locked to the flange 19, and the locking portions 34, 39 of the upper metal fitting 32 and the lower metal fitting 33 are H. When the nut 43 that is screwed into the bolt 40 of the lower metal member 33 is tightened while the flange 19 of the steel 18 is sandwiched in the width direction of the flange 19, the lower metal member 33 is attracted upward, and the locking portion 39 of the lower metal member 33 is connected. The hanging piece 32b of the upper metal member 32 sandwiches the flange 19 of the H steel 18, and the fixed state of the base member 31 is obtained.

  As shown in FIG. 1, the metal fitting body 51 is erected on the base member 31, and the standing piece 52 that fixes the suspension 12 to fix the roofing board to the upper end portion, and the roof board in the standing piece 52. It has two support pieces 53, 54 that extend in alternate directions perpendicular to the gradient direction of the roof plate at both side edges in the gradient direction, and whose lower end portions are fixed to the base member 31. The upright pieces 52 and the support pieces 53 and 54 are formed by bending a single plate material.

  The standing piece 52 is formed in an appropriate width and has a substantially rectangular plate shape extending from the bottom to the top with the same width. The surface direction of the standing piece 52 is the same as the gradient direction of the roof.

  A roof plate receiving portion 55 for receiving a roof plate is formed at the upper end of the upright piece 52. The roof plate receiving portion 55 is a pressure receiving portion that directly receives the roof plate. The roof plate receiving portion 55 has the same width as the portion extending upward from below the upright piece 52 and is formed by bending toward the front side in the forming direction of the roof plate. The front side of the roof plate in the direction of formation means that the roof plate is formed in order from the left side when viewed from the lower side of the roof gradient direction, and therefore the lower side of the roof gradient direction, that is, the left side when viewed from the front. To do. In the illustrated example, the roof plate receiving portion is formed so as to be convex upward and curved along the gradient direction of the roof.

  A square hole 56 for attaching the hanger 12 is formed at an upper portion of the upright piece 52 and a lower position of the roof plate receiving portion 55.

  The support pieces 53, 54 are formed at both ends of the upright piece 52 in the gradient direction of the roof, that is, on the upper side in the gradient direction and the lower side in the gradient direction, and the support piece 53 on the upper side in the gradient direction is the roof plate receiving portion 55 of the upright piece 52. It extends to the front side of the roof plate in the same direction as the roof. The support piece 54 on the lower side in the gradient direction extends to the rear side in the forming direction of the roof plate, that is, to the right side when viewed from the front. FIG. 5 shows a state in which the metal fitting 11 is seen from the front, and FIG. 6 shows a state in which the metal fitting 11 is seen from the back.

  The widths of the support pieces 53 and 54 are narrower than the upright pieces 52. Along the rising direction of the standing piece 52, the width is the same from bottom to top. There are two support pieces 53 and 54, but their widths are the same. Further, as shown in FIGS. 5 and 6, the width of the metal fitting body 51 having the support pieces 53 and 54 extending in the left and right directions is the same as the width of the base member 31.

  A cross section of the intermediate portion in the longitudinal direction of the metal fitting body 11 is as shown in FIG. 7, and the support pieces 53 and 54 are formed by bending the material constituting the standing piece 52 via the bending portion 57. Specifically, two support pieces 53 and 54 extend in opposite directions via bent portions 57 on both side edges of the upright piece 52 extending in the gradient direction of the roof, and the tips of the support pieces 53 and 54 are The base member 31 is flush with the side surface of the upper metal fitting 32.

  A grounding fixing piece 58 that is in surface contact with the upper surface of the base member 31, that is, the flat surface portion 32 a of the upper metal fitting 32, is formed at the lower ends of the support pieces 53 and 54 by bending. The grounding fixing piece 58 is formed in a rectangular shape with the same width as the support pieces 53 and 54 and is bent to the side (inner side) where the upright piece 52 exists. For this reason, the side of the grounding fixing piece 58 on the upright piece 52 side is in contact with the upright piece 52.

  As shown in FIG. 3, the grounding fixing piece 58 has a square hole 58 a in the center, and allows a root bolt 60 to be fixed to the upper bracket 32 of the base member 31 to be inserted. In FIG. 3, 61 is a washer, 62 is a spring washer, and 63 is a nut.

  Of the two support pieces 53 and 54, the support piece 53 on the upper side in the gradient direction of the roof has a length that supports and supports the roof plate receiving portion 55 from below as shown in FIG. That is, the upper end portion of the support piece 53 is the reinforcing portion 65 that contacts the pressure receiving portion. As described above, since the support piece 53 is formed by bending the plate material constituting the upright piece 52 via the bent portion 57 (see FIG. 7), the reinforcing portion 65 is integrated with the upright piece 52 via the bent portion 57. It is.

  Of the support pieces 53 and 54, the support piece 54 on the lower side of the roof gradient direction is set to a height slightly below the position of the square hole 56 for attaching the hanging piece 12 of the standing piece 52. This is to prevent interference when the fixing portion 12a fixes the wide suspension member 12 as shown in FIG.

  When the fixed portion 12a of the hanging member 12 is configured to fit within the width of the upright piece 52 as shown in FIG. 9, the support piece 54 on the lower side in the gradient direction of the roof is extended to the upper end of the upright piece 52. be able to.

  As shown in FIG. 1, the metal fitting 11 configured as described above has a metal fitting body 51 fixed to the upper metal fitting 32 of the base member 31 with a square bolt 60, a nut 63, and the like. The lower metal fitting 33 is held using 43 or the like for use. Since the bracket main body 51 is fixed to the upper bracket 32 by one member, the assembly work can be easily performed. Unlike the case where a plurality of members are fixed to each other, an accurate fixed state can also be obtained.

  The metal fitting body 51 has an elongated shape having one roof plate receiving portion 55 at the upper end of the upright piece 52, and one support piece 53 is accommodated under the roof plate receiving portion 55. The support pieces 53 and 54 at both end edges of the upright piece 52 are narrower than the upright piece 52 and have the same width along the upright direction of the upright piece 52. In addition, the grounding fixing piece 58 at the lower end of the two support pieces 53 and 54 faces inward. For this reason, the metal fitting body 51 has a compact shape that is not bulky.

  For this reason, the handleability in the management and assembly of the metal fitting body 51 is good. Moreover, since it fits nicely on the base member 31, it is possible to avoid an increase in the size of the base member 31 in the case of a metal fitting that can be fixed to the base material without welding. In particular, since the grounding fixing piece 58 faces inward, it is possible to avoid the hindrance to the attachment of the lower metal fitting 33 and the formation of the reinforcing structure of the upper metal fitting 32 for fixing the base member 31 to the base material. .

  When the metal fitting 11 is fixed to the H steel 18 and the roof plate is attached, the support piece 53 on the upper side of the roof plate in the gradient direction is the same as the roof plate receiving portion 55 in the direction of forming the roof plate. Since the support piece 54 on the lower side of the roof plate in the gradient direction is extended to the rear side in the direction of the roof plate in the support pieces 53, 54, the hanging piece is a square goby and the roof plate is attached. Even when it is necessary to attach the suspension, the support piece 54 does not exist on the tightening side, so that the workability is good.

  When the metal fitting 11 is used, the support pieces 53 and 54 of the metal fitting 11 support the standing state of the upright piece 52 both in the gradient direction of the roof and in the direction orthogonal to the gradient direction. For this reason, the standing state of the standing piece 52 can be maintained strongly. In addition, the reinforcing portion 65 of the support piece 53 comes into contact with and supports the roof plate receiving portion 55 which is a pressure receiving portion, and supports the load applied to the roof plate receiving portion 55. This reinforcing portion 65 is the same as the support piece 53 formed by bending the material constituting the standing piece 52 via the bent portion 57 and is integrated with the standing piece 57 via the bent portion 57. The strength of the portion 65 is high. The support pieces 53 and 54 are ground fixing pieces 58 at the lower end portions and are firmly fixed in surface contact with the base member 31.

  For this reason, the load received by the roof plate receiving portion 55 from the roof plate is not supported only by the roof plate receiving portion 55 or the portion close to the roof plate receiving portion 55 but is transmitted to the base member 31 close to the H steel 18. And can be strongly supported. As a result, the metal fitting 11 having a high load supporting ability is obtained.

  In addition, the portion for attaching the lower metal fitting 33 in the upper metal fitting 32 of the base member 31 has a bulging rib 37 and a bent rib 38 so that the shape of the upper metal fitting 32 can be held strongly. Needless to say, it is possible to obtain a firm fixed state with respect to the H steel 18, and it is possible to avoid the upper metal member 32 from being deformed and adversely affecting the fixed state of the metal fitting body 51. Also from this, the favorable metal fitting 11 with high load support capability can be obtained.

  Other examples will be described below. In this description, parts that are the same as or similar to the above-described configuration are given the same reference numerals, and detailed descriptions thereof are omitted.

  The metal fitting 11 shown in FIG. 10 is a metal fitting 11 suitable for the case where the fixing portion 12a of the hanging piece 12 has a shape that is not vertical but horizontal as described above.

  That is, the upright piece 52 of the metal fitting body 51 is not formed with a square hole 56 (see FIG. 1) for fixing the hanger, and the hanger is formed on the surface of the upper portion of the upright piece 52 opposite to the roof plate receiving portion 55. A receiving portion 66 is provided. The hanging member receiving portion 66 is a pressure receiving portion that indirectly receives the load related to the roof plate via the hanging member 12.

  As shown in FIG. 11, the handle receiving portion 66 is formed by integrally fixing a handle receiving metal fitting 66 a having an inverted L shape in front view with a rivet 67 or the like. In FIG. 11, 52a is a through hole for inserting the rivet 67.

  When the hanging bracket 66a is fixed, as shown in FIG. 10, the hanging portion 66 is brought into surface contact with the support piece 54 on the lower side in the gradient direction of the roof. At the center of the upper surface of the hanging piece receiving metal 66a, a hanging bolt 68 is installed upright. The return of the edge of the hanging bracket 66a is a reinforcing return portion 66b.

  The support piece 53 on the upper side in the gradient direction of the roof among the support pieces 53 and 54 is the same as described above and supports the roof plate receiving portion 55. Similarly, the support piece 54 on the lower side in the gradient direction of the roof supports the hanging piece receiving portion 66 by coming into contact with the hanging piece receiving portion 66 from the side.

  The metal fitting 11 having such a configuration has a high load supporting ability as described above. In particular, since the reinforcing portions 65 that support the pressure receiving portions (the roof plate receiving portion 55 and the hanging member receiving portion 66) are provided on the left and right sides, the strength can be further increased.

  When the shape of the fixed portion 12a of the hanging member 12 is as thin as the standing piece 52 as shown in FIG. 12, the support piece 54 extending to the hanging piece receiving portion 66 side is extended to the upper end height of the standing piece 52. Can be extended.

  The metal fitting 11 shown in FIG. 13 is an example in which the roof plate receiving portion 55 at the upper end of the upright piece 52 is formed flat. Reinforcing ribs 55a are formed at the corners.

  The metal fitting 11 shown in FIG. 14 has a reinforcing portion 65 that comes into contact with the suspension receiving portion 66, a vertical surface portion 65a that comes into contact with the suspension receiving metal fitting 66a from the side, and a horizontal surface portion 65b that comes into contact with the bottom. Since the reinforcing portion 65 not only contacts the suspension receiving portion 66 from the side but also supports it from below, a more rigid mounting state can be maintained.

  The hanging piece receiving portion 66 may be formed integrally with the upright piece 52 by bending the upright piece 52.

In the correspondence between the configuration of the present invention and the configuration of the above-described embodiment,
The base material of this invention corresponds to the aforementioned H steel 18,
Similarly,
The pressure receiving part corresponds to the roof plate receiving part 55 and the hanging part receiving part 66,
The present invention is not limited to the above-described configuration, and other configurations can be adopted.

  For example, the metal fitting 11 may be composed of only the metal fitting body 51 without the base member 31, and may be used by being directly fixed to the base material by welding. In this case, it is preferable to form the ground fixing piece 58 by bending it outward.

  The reinforcing portion 65 may be only one that supports the hanging portion receiving portion 66.

  The base material may be a steel material other than the H steel 18, and the base member 31 is appropriately configured according to the shape of the base material.
