Japanese Patent No. 5393258

  By the way, the gypsum board is configured by coating a base paper for board on a wall surface of a core material (wall board) made of gypsum. Therefore, when the wall fixing plate portion of the mounting bracket is fixed to the wall surface of the gypsum board, the wall fixing plate portion is fixed in a state of being in close contact with the surface of the board base paper.

  Here, in the gypsum board, the core material is made of gypsum, whereas the base paper for board is made of soft paper material. Therefore, when a downward rotational force is generated in the wall fixing plate portion of the mounting bracket due to the load of the article placed on the shelf plate, the lower end portion of the wall fixing plate portion is removed from the board base paper or the board base paper by the rotational force. It is assumed that the wall fixing plate portion is inclined so as to cover the gypsum. If it does so, there exists a possibility that an attachment metal fitting and by extension, a shelf board may incline (fall down) downward.

  This invention is made | formed in view of the said situation, and makes it the main objective to provide the wall mounting structure of the shelf board which can suppress the fall of a shelf board below.

  In order to solve the above-mentioned problems, the wall mounting structure of the shelf board of the first invention comprises a wall material formed by coating the wall surface of the wall board with a sheet-like coating material made of paper or resin, It is a wall mounting structure of a shelf plate that is attached to the surface of the covering material so that the shelf plate is attached via an attachment member, and the attachment member is a wall fixing portion that is fixed to the wall material, A shelf fixing part fixed to the shelf, and the wall fixing part has an opposing surface part facing the surface of the covering material, and the opposing surface part is in close contact with the surface. A predetermined range that is fixed to a wall material and overlaps at least the lower end portion of the facing surface portion in the covering material is a cured region that is cured by applying an adhesive or a curing agent. To do.

  According to the present invention, the wall fixing portion of the attachment member is fixed to the wall material in a state where the facing surface portion is in close contact with the surface of the covering material that covers the wall plate. Here, since the covering material is formed of paper or resin which is a relatively soft material, when a downward rotational force is generated in the wall fixing portion due to a downward load from an article acting on the shelf board, There is a possibility that the lower end portion of the opposing surface portion of the fixed portion is sunk into the covering material, and the attachment member and thus the shelf plate tilts (falls) downward. Therefore, in the present invention, as a countermeasure against this, the cured region is formed by applying an adhesive or a curing agent in a predetermined range where at least the lower end portion of the facing surface portion overlaps in the covering material. In this case, since it can suppress that the lower end part of an opposing surface part sinks into a coating | covering material (hardening area | region), it suppresses the fall of the attachment member accompanying this penetration, and by extension, the fall of a shelf board below. Can do.

  A wall mounting structure for a shelf board according to a second aspect is the gypsum board according to the first aspect, wherein the wall material is formed by coating the wall surface of the wall board made of gypsum with a base paper for board as the covering material. The shelf board is attached to the gypsum board so as to protrude to the surface side of the board base paper, and the curing region is provided on the board base paper.

  By the way, as a wall material provided in a building, a gypsum board excellent in fire resistance is often used. The gypsum board is configured by coating a core material (wall board) made of gypsum with a base paper for board (coating material). Therefore, in the configuration in which the shelf board is attached to the gypsum board via the attachment member, the wall fixing portion of the attachment member is fixed to the gypsum board in a state where the opposite surface portion is in close contact with the surface of the base paper for board softer than gypsum. . Therefore, in the present invention, the first invention is applied to such a configuration, and a cured region is formed on the board base paper. In this case, since it can suppress that the lower end part of the opposing surface part of a wall fixing part sinks into the base paper for boards, the fall of the shelf board accompanying such penetration can be suppressed.

  A wall mounting structure for a shelf board according to a third aspect of the present invention is the first or second aspect of the invention, wherein the shelf board is formed with a hole that is opened at an end surface on the wall material side, and the mounting member Is provided in a state of being inserted into the hole.

  According to the present invention, since the attachment member is provided in a state where the attachment member is inserted into the hole formed in the shelf board, the attachment member can be covered with the shelf board. In this case, the shelf board can be attached to the wall material while suppressing the appearance around the shelf board from being damaged. Here, in such an attachment member, it is considered that it is difficult to fix the wall fixing portion to the wall material in a stable state because the vertical dimension of the wall fixing portion can be ensured only by the thickness of the shelf board. Therefore, it is considered that the above-described situation in which the lower end of the facing surface portion sinks into the covering material is likely to occur when a downward rotational force is generated in the wall fixing portion due to the downward load acting on the shelf board. In that respect, in the present invention, since the first invention (configuration related to the curing region) is applied to such a configuration, even in such a configuration, the sinking of the facing surface portion can be suppressed, and as a result, the shelf accompanying such a sinking. The fall of a board can be suppressed.

  A wall mounting structure for a shelf board according to a fourth invention is characterized in that, in the third invention, the hardened region is formed to include the entire region covered with the facing surface portion in the covering material.

  According to the present invention, since the hardened region is formed so as to include the entire region covered with the facing surface portion in the covering material, the entire facing surface portion can be prevented from sinking into the covering material. Thereby, the fall of the shelf board accompanying such indentation can be suppressed further.

  The wall mounting structure for a shelf board according to a fifth aspect of the present invention is characterized in that, in the third or fourth aspect of the invention, the hardened region is formed so as not to protrude from the shelf board.

  By the way, in the coating | covering material, the case where the level | step difference arises in the surface at the boundary of a hardening area | region and another area | region (non-hardening area | region) can be considered. In that case, when a finishing material (wallpaper or the like) is pasted on the surface of the covering material, a step may be generated in the finishing material at the stepped portion, and the appearance may be impaired. Moreover, in the structure by which the surface of a coating | covering material is a finishing surface, there exists a possibility that said boundary may be conspicuous and an external appearance may be impaired. Therefore, in the present invention, in view of these points, the hardened region is formed so as not to protrude from the shelf board. In this case, since the boundary between the hardened region and the other region in the covering material can be covered with the shelf board, it is possible to avoid the appearance from being damaged by the boundary.

  A wall mounting structure for a shelf board according to a sixth aspect of the present invention is the invention according to any one of the third to fifth aspects, wherein a base plate is provided on the back side of the wall material, and the base plate is provided with the wall. A fixing tool is driven through the fixing portion and the wall material, and the wall fixing portion is fixed to the wall material by the fixing device, and the wall fixing portion extends from the facing surface portion to the wall. A shaft extending through the wall material to the back side of the material is provided, and an insertion hole for inserting the shaft is formed in the base plate.

  According to the present invention, the shaft provided in the wall fixing portion extends through the wall material to the back surface side of the wall material, and the shaft is inserted in the base plate provided on the back surface side of the wall material. Is plugged into the department. In this case, even if a downward rotational force is generated on the wall fixing portion (specifically, the portion provided on the surface side of the wall material in the wall fixing portion) due to the downward load acting on the shelf board, the shaft of the wall fixing portion is moved upward. As a result, the downward rotation of the wall fixing portion can be suppressed. Thereby, it becomes possible to further suppress the falling of the mounting member and the shelf board.

  A wall mounting structure for a shelf board according to a seventh aspect of the present invention is that, in the sixth aspect, the insertion portion of the shaft inserted into the insertion hole portion increases the frictional resistance with the base plate on the outer peripheral surface thereof. A high friction structure is formed.

  By the way, in the configuration of the sixth aspect of the invention, when a downward rotational force is applied to the wall fixing portion due to a downward load acting on the shelf plate, the shaft can be prevented from tilting upward. It is assumed that a pulling force toward the side pulled out from the insertion hole by the rotational force also acts. In this case, the pulling force may cause the shaft (and the wall fixing portion) to be displaced toward the drawing side, and the wall fixing portion may be easily rotated downward.

  Therefore, in the present invention, in view of this point, a high friction structure is formed on the outer peripheral surface of the insertion portion inserted into the insertion hole portion in the shaft. In this case, since the frictional resistance between the insertion portion and the base plate is increased, it is possible to apply a resistance force to the pulling force acting on the shaft. Thereby, the displacement to the said extraction side of a shaft can be suppressed, and by extension, rotation of the wall fixing part accompanying this displacement can be suppressed. Therefore, in this case, it is possible to further suppress the falling of the mounting member and thus the shelf board.

  A wall mounting structure for a shelf board according to an eighth aspect of the present invention is the sixth or seventh aspect, wherein the wall fixing portion is a pair of fixtures disposed on both sides of the shaft in the width direction of the shelf board. Is fixed to the wall member, and each of the fixtures is arranged at a different height from the shaft.

  According to the present invention, the wall fixing portion is fixed to the wall member by the pair of fixing tools (screws, nails, bolts, etc.) disposed on both sides of the shelf in the width direction of the shelf board, and each of these fixing tools Are arranged at different heights from the shaft. In this case, it is possible to prevent the fixtures and the shaft from being aligned in a straight line in the horizontal direction. Therefore, unlike the case where the fixtures and the shaft are arranged in a straight line in the horizontal direction, rotate the straight line. It is possible to suppress the downward rotation of the center wall fixing portion. Thereby, the fall of a shelf board can be suppressed further.

  The wall mounting structure of the shelf board of the ninth invention is the invention according to any one of the sixth to eighth inventions, wherein the base plate is longer in the vertical direction than the depth dimension of the shelf board. It is characterized by.

  By the way, when the wall fixing portion tries to rotate downward due to the downward load acting on the shelf plate, the wall material to which the wall fixing portion is fixed may be deformed following the rotation of the wall fixing portion. At this time, it is conceivable that the wall material is deformed into a corrugated plate in which the periphery of the fixed portion where the wall fixing portion is fixed undulates up and down. Therefore, in the present invention, in view of such a point, the vertical length of the base plate provided on the back surface side of the wall material is made longer than the depth dimension of the shelf board. In this case, since it becomes possible to cover the periphery of the fixed portion where the wall fixing portion is fixed in the wall material with a base plate with a sufficient vertical dimension from the back side, it is possible to suitably suppress the deformation of the wall material. As a result, it is possible to suppress the falling of the shelf board based on the above deformation.

  The gypsum board 14 corresponds to a wall material, the core material 14a corresponds to a wall plate, and the board base paper 14b corresponds to a covering material. Similarly to the gypsum board 14, the gypsum board 15 is also configured by covering a base paper for board with a core material.

  A shelf board 21 is attached to the gypsum board 14 so as to protrude toward the first living room K1. The shelf board 21 is a so-called wall-mounted shelf board, and is formed in a rectangular plate shape having a predetermined thickness with a wood-based material. The shelf board 21 is horizontally oriented when attached to the gypsum board 14, and the upper surface thereof serves as a placement surface on which articles are placed.

  In the illustrated example, only one shelf plate 21 (one step) is attached to the gypsum board 14, but a plurality of shelf plates 21 may be attached to the gypsum board 14 in a vertical direction.

  The shelf board 21 is attached to the gypsum board 14 via an attachment fitting 22 as an attachment member. A plurality of mounting brackets 22 (specifically two) are provided at a predetermined interval in the width direction of the shelf board 21, and the shelf board 21 is attached to the gypsum board 14 via the plurality of mounting brackets 22. Yes. Hereinafter, a structure for mounting the shelf board 21 to the gypsum board 14 using the mounting bracket 22 will be described. FIG. 2 is a longitudinal sectional view showing a state in which the shelf board 21 is attached to the gypsum board 14 via the mounting bracket 22.

  As shown in FIG. 2, the mounting bracket 22 is fixed to the gypsum board 14 from the first living room K1 side. A protruding portion 22 a that protrudes from the gypsum board 14 toward the first living room K <b> 1 in the mounting bracket 22 is accommodated inside the shelf board 21. That is, the shelf plate 21 is formed with a hole 23 that opens at the end face 21a on the gypsum board 14 side, and the protruding portion 22a is inserted into (inserted into) the hole 23. As a result, the protruding portion 22 a and thus the mounting bracket 22 are fixed to the shelf plate 21. Note that the protruding portion 22a inserted into the hole 23 may be bonded and fixed to the shelf board 21 using an adhesive.

  If the mounting bracket 22 is used, the mounting bracket 22 can be concealed by the shelf board 21, so that the shelf board 21 can be attached to the gypsum board 14 while suppressing the appearance around the shelf board 21 from being damaged. it can. Incidentally, in this embodiment, a commercially available product (general-purpose product) is used as the mounting bracket 22.

  Next, the configuration of the mounting bracket 22 will be described in detail with reference to FIGS. FIG. 3 is a perspective view showing a state in which the mounting bracket 22 is fixed to the gypsum board 14. FIG. 4 is an exploded perspective view showing the mounting bracket 22 in an exploded state. FIG. 5 is a cross-sectional view showing a state in which the mounting bracket 22 is fixed to the gypsum board 14. In FIG. 4, for the sake of convenience, the outer edge of the end surface 21 a of the shelf board 21 is indicated by a virtual line.

  As shown in FIGS. 3 to 5, the mounting bracket 22 includes a wall fixing part 25 that is fixed to the gypsum board 14 and a shelf board fixing part 26 that is fixed to the shelf board 21. The wall fixing portion 25 is fixed to the surface of the gypsum board 14 (the surface on the first living room K1 side), and passes through the gypsum board 14 from the fixing plate portion 27 to the back side of the gypsum board 14. And an extending shaft 28.

The fixed plate portion 27 is made of a rectangular flat plate-shaped steel plate having a long shape. The fixed plate portion 27 has a width (length in the short direction) smaller than the thickness of the shelf plate 21. The fixed plate portion 27 is fixed to the surface of the gypsum board 14 (specifically, the base paper 14b for board) with its longitudinal direction facing the width direction of the shelf plate 21 (in other words, the wall width direction of the partition wall 11). Specifically, the fixed plate portion 27 is fixed to the gypsum board 14 with its plate surface 27a in close contact with the surface of the board base paper 14b. Further, the fixed plate portion 27 is located at the center portion in the thickness direction of the shelf plate 21 in such a fixed state. The plate surface 27a of the fixed plate portion 27 corresponds to the facing surface portion.

  The fixed plate portion 27 is fixed to the gypsum board 14 using a plurality (specifically, two) screws 29. In this case, a rectangular flat base plate 31 is provided on the back side of the gypsum board 14, and a screw 29 is driven against the base plate 31 while penetrating the fixed plate portion 27 and the gypsum board 14. Yes. Thereby, the fixing plate portion 27 is fixed to the gypsum board 14 in a state where the gypsum board 14 is sandwiched between the fixing plate portion 27 and the base plate 31. The screw 29 corresponds to a fixture.

  The fixing plate portion 27 will be described in more detail. The fixing plate portion 27 is formed with a pair of holes 32 penetrating in the thickness direction at both ends in the longitudinal direction. The gypsum board 14 is formed with holes 33 penetrating in the thickness direction at positions corresponding to the holes 32. The screws 29 are driven against the base plate 31 from the first room K1 side through the fixing plate 27 and the holes 32 and 33 of the gypsum board 14. A flat washer 34 (flat washer) is interposed between the head 29 a of the screw 29 and the fixed plate portion 27. The flat washer 34 is of a so-called wide type, and its outer diameter is larger than half the width of the fixed plate portion 27. The flat washer 34 increases the fixing strength of the fixing plate portion 27 with the screw 29.

  The shaft 28 is made of a metal round bar, and one end thereof is fixed to the central portion of the fixed plate portion 27. Specifically, a hole 36 that penetrates in the thickness direction is formed in the central portion of the fixed plate portion 27, and the one end portion of the fixed plate portion 27 is inserted into the hole portion 36 with one end portion of the shaft 28 inserted therein. It is fixed by welding.

  The shaft 28 is inserted into a hole 37 (through hole) formed in the gypsum board 14 and a hole 38 (through hole) formed in the base plate 31. The hole 37 has a hole diameter larger than the outer diameter of the shaft 28, and the hole 38 has a hole diameter the same as or slightly larger than the outer diameter of the shaft 28. Therefore, the shaft 28 is attached to the base plate 31 by being inserted (inserted) into the hole 38 of the base plate 31. The hole 38 corresponds to the insertion hole.

  The shaft 28 is positioned at the center of each hole 32 for inserting the screw 29 in the fixed plate portion 27. In this case, both the shaft 28 and each hole 32 are located at the same height position in the fixed plate portion 27 (specifically, the central portion in the width direction of the fixed plate portion 27). The fixed plate portion 27 is arranged in a straight line in the longitudinal direction (horizontal direction).

  The shelf fixing part 26 includes a connecting part 41 connected to the fixing plate part 27 of the wall fixing part 25, and a shaft 42 extending from the connecting part 41 toward the opposite side of the fixing plate part 27. The connecting portion 41 is made of metal and is fixed to the plate surface of the fixed plate portion 27 on the first living room K1 side. The connecting portion 41 includes a rectangular parallelepiped main body portion 41a and a pair of flange portions 41b protruding left and right at the end of the main body portion 41a on the fixing plate portion 27 side.

  The main body portion 41 a has a vertical dimension that is substantially the same as the width of the fixed plate portion 27, and a horizontal dimension (horizontal size) that is half or less than the length of the fixed plate portion 27. The main body portion 41 a is located at the central portion in the longitudinal direction of the fixed plate portion 27. Each of the pair of flange portions 41 b is fixed to the fixing plate portion 27 with bolts 44. Specifically, each flange portion 41 b is formed with a hole portion 45, and the fixing plate portion 27 is formed with a screw hole portion 46 at a position corresponding to each hole portion 45. The bolts 44 are screwed into the screw hole portions 46 of the fixed plate portion 27 through the hole portions 45 of the flange portion 41b. Note that a relief hole 48 is formed in the gypsum board 14 in order to avoid interference with the bolts 44.

  The shaft 42 is made of a metal round bar, and one end thereof is welded and fixed to the main body 41 a of the connecting portion 41. The shaft 42 is arranged on the same axis as the shaft 28 of the wall fixing portion 25.

  By the way, as described above, the wall fixing portion 25 of the mounting bracket 22 has the fixing plate portion 27 (specifically, the plate surface 27a) as the base paper 14b for the gypsum board 14, that is, the gypsum board 14 and the core material 14a (gypsum). It is fixed to the gypsum board 14 in close contact with the softer board base paper 14b. In such a configuration, when a downward rotational force is generated in the fixed plate portion 27 due to a downward load from the article acting on the shelf plate 21, the lower end portion of the fixed plate portion 27 (plate surface 27a) is applied to the board base paper 14b. There is a possibility that the fixing plate portion 27 may be tilted downward. If it does so, there exists a possibility that the attachment metal fitting 22 and by extension, the shelf board 21 may incline (fall down) below. Therefore, in the present embodiment, as a countermeasure against this, a characteristic configuration is provided on the gypsum board 14 side. The characteristic configuration will be described below.

  As shown in FIGS. 3 and 4, a predetermined region of the base paper 14 b for the gypsum board 14 is a cured region 50 that is cured by applying an adhesive. 3 and 4, the cured region 50 is shown with a dot hatch. The cured region 50 is a rectangular region that is long in the lateral direction (the width direction of the gypsum board 14), and is formed so as to include the entire region covered by the fixed plate portion 27 (plate surface 27a) on the board base paper 14b. Has been. Therefore, the curing region 50 is provided over the entire region (the entire region in the length direction of the fixed plate portion 27) in the lower end overlapping region where the lower end portion of the fixed plate portion 27 overlaps the board base paper 14b.

  The curing region 50 has a vertical width H that is larger than the width of the fixed plate portion 27, and a part thereof protrudes above and below the fixed plate portion 27. The vertical width H of the hardened region 50 is smaller than the thickness t of the shelf board 21, and the entire area is within the range of the thickness t of the shelf board 21. Therefore, the hardened region 50 is prevented from protruding up and down from the shelf board 21 with the shelf board 21 attached.

  The length of the curing region 50 in the lateral direction (left and right direction) is longer than the length (in the longitudinal direction) of the fixed plate portion 27, and a part of the cured region 50 protrudes from the fixed plate portion 27 to the left and right. Further, the cured region 50 has a lateral length that does not protrude from the end of the shelf plate 21 in the width direction. Therefore, the curing region 50 does not protrude from the top, bottom, left, or right from the shelf board 21 with the shelf board 21 attached.

  The curing region 50 is formed by applying a urethane-based adhesive thinly on the surface of the board base paper 14b, and then drying and curing the adhesive. The cured region 50 is harder than the region other than the cured region 50 (referred to as the non-cured region 51) in the board base paper 14b, so that the resistance force to the compressive force (in the thickness direction) is not cured in the cured region 50. It is higher than the area 51.

  As described above, since the curing region 50 is provided in the overlapping region where the lower end portion of the fixed plate portion 27 (plate surface 27a) overlaps in the board base paper 14b, the fixed plate portion 27 is caused by the downward load acting on the shelf plate 21. Even if a downward rotational force is generated, the lower end portion of the fixed plate portion 27 (plate surface 27a) can be prevented from sinking into the board base paper 14b (cured region 50). Thereby, the downward fall of the attachment metal fitting 22 accompanying such indentation can be suppressed, and by extension, the downward fall of the shelf board 21 can be suppressed.

  In addition, although illustration is abbreviate | omitted, after the hardening area | region 50 is formed in the base paper 14b for boards, the wallpaper (cross) as a finishing material is affixed on the surface of the gypsum board 14 (board base paper 14b). Thereby, the hardening area | region 50 will be in the state hidden by the wallpaper. The wallpaper is affixed with its edge abutted against the shelf board 21.

  Moreover, in this embodiment, the fall suppression means which suppresses the fall of the shelf board 21 other than the hardening area | region 50 mentioned above is provided. Such suppression means includes those related to the base plate 31 and those related to the shaft 28 of the wall fixing portion 25. First, the fall prevention means regarding the base plate 31 will be described.

  As shown in FIG. 1, the base plate 31 is made of a structural plywood having a rectangular plate shape that is long in the vertical direction. The base plate 31 is provided so as to straddle between the horizontal frame members 13 b adjacent to each other in the base frame 13 on the back side of the gypsum board 14. And the upper end part and lower end part of the baseplate 31 are being fixed to these horizontal frame material 13b with the bis | screw etc., respectively. The base plate 31 has a length L in the vertical direction longer than the depth dimension W of the shelf plate 21, for example, a length of 480 mm.

  As described above, the wall fixing portion 25 (specifically, the fixing plate portion 27) of the mounting bracket 22 is provided on the side opposite to the base plate 31 with the gypsum board 14 interposed therebetween. The fixed plate portion 27 is fixed to the gypsum board 14 at the center height in the vertical direction of the base plate 31. In the fixed state of the fixing plate portion 27, the vertical distance from the fixing plate portion 27 (wall fixing portion 25) to the upper end portion and the lower end portion of the base plate 31 is from the gypsum board 14 of the protruding portion 22 a of the mounting bracket 22. It is the same as or longer than the protrusion length K.

  According to said structure, it becomes possible to cover the periphery of the fixed site | part to which the fixed board part 27 is fixed in the gypsum board 14 with sufficient vertical dimension by the baseplate 31 from the back surface side. When the fixed plate portion 27 tries to rotate downward due to the downward load acting on the shelf plate 21, the gypsum board 14 may be deformed following the rotation of the fixed plate portion 27. For example, there is a possibility that the periphery of the fixed portion where the fixed plate portion 27 is fixed in the gypsum board 14 may be deformed so as to wave up and down. In that respect, it is possible to suitably suppress the deformation of the gypsum board 14 by covering the gypsum board 14 from the back side with a sufficient vertical dimension as described above. As a result, it is possible to suppress the falling of the mounting bracket 22 and the shelf 21 due to such deformation.

  Subsequently, the fall prevention means related to the shaft 28 will be described.

  As shown in FIG. 4, the insertion portion 28 a (see also FIG. 5) inserted into the hole 38 of the base plate 31 in the shaft 28 has a high friction portion 53 that increases the frictional resistance with the base plate 31 on the outer peripheral surface thereof. Is formed. In FIG. 4, the range in which the high friction portion 53 is formed is shown with dot hatching. The high-friction portion 53 is formed by subjecting the outer peripheral surface (surface) of the shaft 28 to surface processing for increasing the surface roughness using a sander or the like. The high friction portion 53 is formed over the entire area in the axial direction on the outer peripheral surface of the insertion portion 28a.

  The high friction portion 53 is formed only on a part of the outer peripheral surface of the insertion portion 28a in the circumferential direction, specifically, only on the upper portion of the outer peripheral surface. In this case, the high friction portion 53 is formed in a predetermined range including the upper end portion on the outer peripheral surface of the insertion portion 28a, and the predetermined range is, for example, the upper half of the outer peripheral surface of the insertion portion 28a. Thus, the high friction part 53 is formed in the outer peripheral surface of the insertion part 28a, and the frictional resistance with the baseplate 31 is raised in the insertion part 28a. In this case, the high friction portion 53 corresponds to a high friction structure.

  Incidentally, the high friction part 53 does not necessarily need to be formed in the upper half of the outer peripheral surface of the insertion part 28a, and may be formed only in the upper end part. Moreover, the high friction part 53 may be formed in the outer peripheral surface whole region of the insertion part 28a. Moreover, the high friction part 53 may be formed only in a part of axial direction in the outer peripheral surface of the insertion part 28a.

  According to said structure, since the high friction part 53 is formed in the outer peripheral surface of the insertion part 28a of the shaft 28, since the frictional resistance of the insertion part 28a and the baseplate 31 is raised, shelves When the downward load acting on the plate 21 generates a downward rotational force on the fixed plate portion 27 and a pulling force on the side to be pulled out from the hole 38 acts on the shaft 28, a resistance force is applied to the pulling force. can do. Thereby, it can suppress that the shaft 28 displaces to the extraction side, As a result, it can suppress that the stationary plate part 27 rotates below with such displacement. Therefore, in this case, it is possible to further suppress the falling of the mounting bracket 22 and thus the shelf board 21.

  Further, when a downward rotational force is generated on the fixed plate portion 27 due to a downward load acting on the shelf plate 21, the shaft 28 tends to tilt upward, so that the upper portion of the outer peripheral surface of the shaft 28 is the base plate 31. It is assumed that it contacts the inner peripheral surface of the hole 38. Therefore, in the above configuration, paying attention to this point, the high friction portion 53 is formed on the upper portion of the outer peripheral surface of the insertion portion 28a. In this case, since the function of increasing the frictional resistance between the insertion portion 28a and the base plate 31 by the high friction portion 53 can be preferably exerted, the shelf plate 21 falls due to the displacement of the shaft 28 toward the drawing side. Can be suitably suppressed.

  Furthermore, since the high friction portion 53 is formed only on the upper portion of the outer peripheral surface of the shaft 28, surface processing when forming the high friction portion 53 can be made relatively easy.

  Incidentally, the high friction portion 53 is not necessarily formed by increasing the surface roughness of the outer peripheral surface of the insertion portion 28a. For example, a concave portion and a convex portion are arranged in the axial direction on the outer peripheral surface of the insertion portion 28a. An uneven structure may be formed, and the uneven structure may be a high friction part.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  The hardened region 50 was formed so as to include the entire region covered with the fixing plate portion 27 (plate surface 27a) of the wall fixing portion 25 in the board base paper 14b of the gypsum board 14. In this case, since it is possible to suppress the entire fixing plate portion 27 from being sunk into the board base paper 14b, it is possible to further suppress the falling of the mounting bracket 22 and the shelf 21 due to the staking.

  Since the hardened region 50 is formed so as not to protrude from the shelf plate 21, the boundary between the hardened region 50 and the non-hardened region 51 can be covered by the shelf plate 21. In this case, even if a level difference occurs at the boundary, the wallpaper is not pasted across the level difference, so that it is possible to avoid a level difference following the level difference on the wallpaper. Thereby, falling of the shelf board 21 can be suppressed, avoiding that the external appearance of the partition wall 11 is impaired.

  Further, by providing the hardened region 50 on the board base paper 14b of the gypsum board 14, that is, by devising the configuration on the gypsum board 14 side, the falling of the shelf board 21 is suppressed. In this case, since it is not necessary to devise specially about the structure on the side of the mounting bracket 22, it is possible to suppress the falling of the shelf board 21 relatively easily while using the commercially available mounting bracket 22.

  The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

  (1) In the said embodiment, although the hardening area | region 50 was formed so that the whole area | region covered with the fixed board part 27 (plate surface 27a) in the board base paper 14b of the gypsum board 14 might be changed, this is changed. The hardened region 50 may be formed only in the lower end overlapping region where the lower end portion of the fixed plate portion 27 overlaps in the board base paper 14b. If the hardening region 50 is formed at least in the lower end overlapping region, the lower end portion of the fixed plate portion 27 can be prevented from sinking, and therefore the falling of the shelf plate 21 due to the penetration can be suppressed.

  Moreover, you may form the hardening area | region 50 so that one part may protrude from the shelf board 21. FIG. In this case, the boundary between the hardened region 50 and the non-hardened region 51 is exposed to the outside of the shelf board 21. If there is no step at the boundary, the wallpaper is pasted on the gypsum board 14, and then the above-mentioned on the wallpaper. In this case, the shelf plate 21 can be prevented from falling down without impairing the appearance of the partition wall 11.

  (2) In the said embodiment, although the hardening area | region 50 was formed by apply | coating a urethane type adhesive to the base paper 14b of the gypsum board 14, the hardening area | region 50 was apply | coated by adhesives other than a urethane type adhesive. May be formed. Further, the hardened region 50 may be formed by applying a hardener to the board base paper 14b instead of the adhesive.

  (3) The wall mounting structure of the shelf board 21 in the present invention is not necessarily applied only to the mounting bracket 22 of the above-described embodiment, and can also be applied to the mounting bracket 22 having other configurations. For example, in the mounting bracket 22 of the above embodiment, the wall fixing part 25 fixed to the gypsum board 14 and the shelf fixing part 26 fixed to the shelf board 21 are fixed by bolts 44 and integrated. The present invention may be applied to a mounting bracket in which the wall fixing portion 25 and the shelf board fixing portion 26 are integrally formed by welding or the like.

  In the mounting bracket 22 of the above embodiment, the wall fixing portion 25 has the shaft 28, but the wall fixing portion 25 does not have the shaft 28, that is, the wall fixing portion is composed only of the fixing plate portion 27. The present invention may be applied to the mounting bracket.

  The mounting bracket 22 of the above embodiment is a so-called invisible mounting bracket that is provided by being inserted into the hole 23 of the shelf board 21, but a so-called exposed mounting that is provided to be exposed to the outside of the shelf board 21. You may apply this invention to a metal fitting. As this type of mounting bracket, for example, an L-shape having a shelf fixing plate portion fixed to the lower surface of the shelf plate 21 and a wall fixing plate portion fixed to the surface of the gypsum board 14 (board base paper 14b). The mounting bracket (angle) can be considered. In this case, the wall fixing plate portion is fixed to the gypsum board 14 with its plate surface (corresponding to the facing surface portion) being in close contact with the surface of the board base paper 14b. Accordingly, even in such a configuration, by providing the hardened region 50 in the board base paper 14b, it is possible to suppress the lower end of the wall fixing plate portion (plate surface) from sinking into the board base paper 14b. The fall of the plate 21 can be suppressed.

  (4) For example, as shown in FIG. 6, a pair of screws 29 for fixing the fixing plate portion 27 of the wall fixing portion 25 to the gypsum board 14 may be provided at different height positions from the shaft 28. In FIG. 6, each hole portion 56 for inserting the screw 29 formed in the fixed plate portion 27 has a long and long hole shape. Each of these holes 56 has a vertical length longer than the outer diameter of the shaft 28, and extends across the shaft 28 in the vertical direction. Of these holes 56, one hole 56a has a screw 29a disposed below the hole 56a, and the other hole 56b has a screw 29b disposed above the hole 56b. In this case, each of the screws 29a and 29b is disposed at a height position different from that of the shaft 28. Specifically, the screw 29a is disposed at a position lower than the shaft 28, and the screw 29b is disposed at a position higher than the shaft 28. ing. Accordingly, the screws 29a and 29b and the shaft 28 are arranged so as not to be aligned in a straight line in the horizontal direction.

  Here, when the screws 29a, 29b and the shaft 28 are arranged in a straight line in the horizontal direction, there is a possibility that the fixed plate portion 27 is rotated downward about the straight line. In the configuration in which the screws 29a and 29b and the shaft 28 are not aligned in the horizontal direction as described above, it is possible to suppress the downward rotation of the mounting bracket 22 with the straight line as the rotation center. Thereby, the fall of the shelf board 21 can be suppressed further.

  If the screws 29a and 29b and the shaft 28 are not aligned in the horizontal direction, the holes 56a and 56b are not necessarily formed by long holes, and may be formed by round holes, for example.

  (5) In the above-described embodiment, as the fall suppression means for suppressing the fall of the shelf board 21, besides the curing region 50 provided on the board base paper 14 b, the fall prevention means for the base plate 31 (specifically, the upper and lower lengths of the base board 31). The length L is configured to be longer than the depth dimension W of the shelf plate 21), and a tilt-inhibiting means for the shaft 28 (specifically, a configuration in which the high friction portion 53 is formed on the outer peripheral surface of the insertion portion 28a). Any one or both of the fall prevention means for the base plate 31 and the fall prevention means for the shaft 28 may be omitted. Even in that case, the shelf region 21 can be prevented from falling because the curing region 50 is provided.

  (6) In the above embodiment, the shelf board 21 is attached to the gypsum board 14 before the wallpaper (cross) is pasted on the surface of the gypsum board 14 (specifically, the base paper 14b for board). It is also conceivable to attach the shelf 21 to the gypsum board 14 after pasting the wallpaper on the surface. In this case, when the wall fixing portion 25 of the mounting bracket 22 is fixed to the gypsum board 14, the fixing plate portion 27 (plate surface 27a) is fixed in close contact with the surface of the wallpaper. In this case as well, there is a possibility that the fixing plate portion 27 may be depressed.

  Therefore, in such a configuration, it is conceivable to form the cured region 50 by applying an adhesive or a curing agent to the wallpaper. If it does so, it can suppress that the fixed board part 27 sinks into a wallpaper, As a result, the fall of the shelf board 21 accompanying such sinking can be suppressed. In this case, the gypsum board 14 corresponds to a wall board, and the wallpaper corresponds to a covering material. Moreover, a wall material is comprised by the plasterboard 14 and wallpaper.

  Further, when a plywood is used as a wall board instead of the gypsum board 14 and a wallpaper is pasted on the wall surface of the plywood, it is hardened when attaching the shelf board 21 in the same manner as in the above case where the gypsum board 14 is used as the wall board. A structure for suppressing the collapse of the shelf board 21 by the region 50 can be applied.
