Description

  The present invention relates to a mounting hardware for a lightweight cellular concrete panel (ALC panel). More specifically, the present invention relates to an attachment hardware for attaching an ALC panel to a building frame via an angle member having an L-shaped cross section, and an ALC panel attachment structure using the same.

  As an ALC panel mounting structure, a mounting structure (a lightweight cellular concrete panel mounting structure (conventional structure) 20) as shown in FIG. 8 is widely adopted. In this mounting structure, the embedded anchor 21 embedded in the ALC panel 2 and the panel joint surface of the Inazuma plate 8 used as a mounting hardware are joined by the anchor bolt 4. On the other hand, between the panel joining surface of the Inazuma plate 8 and another surface formed so that a step is generated by two-stage bending, and the back surface of the ALC panel 2, The angle member 3 having a L-shaped joined cross section is fixed in a sandwiched manner (Patent Document 1).

  Here, with respect to the embedment of the embedded anchor in the ALC panel, the embedded anchor previously welded to the reinforcing reinforcing bar is installed in a mold for injecting the ALC slurry, so that the embedded anchor is previously installed in the ALC panel. Generally, it is based on a method of embedding in a predetermined position inside the. In the case of this method, if there is even a slight error in the construction state on the housing side or the position where the embedded anchor of the ALC panel is embedded, it may be difficult to attach the ALC panel. If such an error generated in the panel manufacturing stage can be absorbed in the mounting hardware, it is possible to reduce the construction defects such as the wall structure using the ALC panel and improve the construction speed. For this reason, there is a need for a mounting hardware that can absorb errors in the embedded position of the embedded anchor.

  As mounting hardware that can meet such demands, the insertion hole of the anchor bolt is a long hole that can absorb the above positional error, and the protruding part protrudes from the surface of the flat plate part in which such insertion hole of the anchor bolt is formed. There has been proposed an attachment hardware in which a step is formed on the contact surface by forming only on both ends of the hardware (Patent Document 2).

  According to the mounting hardware disclosed in Patent Document 2, an error in the embedded position of the embedded anchor is absorbed in the mounting hardware without a change in the positional relationship between the ALC panel and the building frame, and the panel mounting work The above error can be eliminated in stages.

  However, the thickness of the housing-side mounting member (angle member or the like) sandwiched between the mounting hardware and the back surface of the ALC panel is not necessarily constant even in the same building. That is, the step is not necessarily constant. In order to cope with such a difference in level difference, it is necessary to manufacture a necessary number of different types of mounting hardware having different shapes in a hardware manufacturing factory or the like, which increases labor and cost. In this regard, further improvement of the mounting hardware has been sought.

<Mounting hardware for lightweight cellular concrete panel>
As shown in FIGS. 1 to 3, the mounting hardware 1 is used as one hardware in a state where the main body plate 11 and the auxiliary plate 12 are overlapped and joined. The main body plate 11 and the auxiliary plate 12 are both plate-like metal members whose outer edge shapes in a plan view are both substantially rectangular. The mounting hardware 1 is a mounting hardware characterized in that these two metal members are combined.

(Main body plate)
First, details of the main body plate 11 will be described. As shown in FIG. 4, the main body plate 11 is a plate-shaped metal member that includes at least the flat plate portion 111 and has a substantially rectangular shape in plan view.

  The main body plate 11 is a portion that becomes a substrate layer in the mounting hardware 1. The mechanical strength required for the mounting hardware 1 is mainly secured by the body plate 11. Therefore, the main body plate 11 is required to have a thickness and shape that can meet such requirements. As a result, the thickness of the main body plate 11 is usually thicker than that of the auxiliary plate 12.

  As shown in FIG. 4, the main body plate 11 is provided with a long hole 113 having a major axis in a direction parallel to both sides of the set (Y direction). It is formed at a position including the center of the flat plate portion 111 to be configured.

  Further, it is preferable that rib portions 112 extending from the same portion and projecting in the same vertical direction with respect to the flat plate portion 111 are formed on both side edges of the flat plate portion 111 of the main body plate 11. The rib portion 112 is a bent portion mainly for reinforcing the bending strength of the mounting hardware 1. A preferable example of the cross-sectional shape of the rib portion 112 in the direction orthogonal to the Y direction (X direction) is a U shape as shown in FIG. 4 or a tapered shape.

  In addition, as shown in FIGS. 1 and 3, at one end in the longitudinal direction of the flat plate portion 111 of the main body plate 11, a direction in which the rib portion 112 protrudes from the same portion and protrudes from the flat plate portion 111. The bending terminal part 114 which protrudes in the same direction may be formed. The bending end portion 114 is also a bending portion mainly for reinforcing the bending strength of the mounting hardware 1.

  The main body plate 11 described above includes, for example, a single metal plate punched into a predetermined shape, a bending process for appropriately forming the rib portion 112 at a predetermined position, and a perforation for forming the long hole 113. It can be formed by processing.

(Auxiliary plate)
Next, the details of the auxiliary plate 12 will be described. As shown in FIG. 5, the auxiliary plate 12 has a configuration including at least a protruding flat plate portion 121 and a pair of protrusions 124 extending from both side edge portions thereof, and has a substantially rectangular shape in plan view. It is a plate-shaped metal member. Details of the shape and action and effect of the pair of protrusions 124 will be described later together with the description of the overall configuration.

  The protrusion may be a protrusion 124 having a substantially U-shaped cross section as shown in FIG. 5, but as shown in FIG. 9, the protrusion has a wall-like shape rising vertically from the protruding flat plate 121. More preferably, the protrusion 124A is a protrusion. Then, as shown in FIG. 10, in the integrated mounting hardware 1A, the protrusion 124A is brought into contact with the vicinity of the outer edge of the long hole 113 of the main body plate 11 from below, and the main body plate 11 is supported at the contact portion. A configuration is preferable. The details of the shape and the operational effect of the protruding portion 124A will be described later together with the description of the overall configuration.

  The auxiliary plate 12 is a portion that becomes an auxiliary layer in the mounting hardware 1. The auxiliary plate 12 is superimposed on the main body plate 11 mainly for the purpose of forming an appropriate step in the joint surface of the mounting hardware 1.

  As shown in FIG. 5, the auxiliary plate 12 is formed with a vertically long notch slit 123 along a direction (Y direction) parallel to the pair of both sides. The notch slit 123 is formed at a position equidistant from the both sides of the auxiliary plate 12, that is, at a position including the center of the protruding flat plate portion 121 constituting the auxiliary plate 12. Further, the notch slit 123 is formed so that the long hole 113 of the main body plate 11 and the notch slit 123 of the auxiliary plate 12 are flat when the mounting hardware 1 in which the main body plate 11 and the auxiliary plate 12 are integrated. It is formed so as to be in a state where they are arranged at positions overlapping each other in view (see FIGS. 1 and 2).

  Further, both outer edge portions of both ridges 124 formed to extend from both side edges of the protruding flat plate portion 121 of the auxiliary plate 12 extend from the same portion to the surface of the protruding flat plate portion 121. On the other hand, it is preferable that auxiliary rib portions 122 that protrude in the same vertical direction are formed. The auxiliary rib portion 122 is a bent portion for assisting the action of the rib portion 112 and reinforcing the bending strength of the mounting hardware 1. As shown in FIG. 3, the cross-sectional shape of the auxiliary rib portion 122 in the direction orthogonal to the Y direction (X direction) is the main body plate in the use state of the mounting hardware 1 in which the main body plate 11 and the auxiliary plate are integrated. Any shape that can be overlapped with the 11 ribs 112 without any gaps is acceptable. To that extent, specifically, a U-shaped shape as shown in FIG. 5 or one having such a tapered shape can be given as a preferred example.

  The auxiliary plate 12 described above is formed by, for example, bending a single metal plate punched into a predetermined shape to form the protrusions 124 (or 124A) and the auxiliary ribs 122 appropriately at predetermined positions. , And by performing a cutting process for forming the notch slit 123.

(overall structure)
As described above, the two metal members, ie, the main body plate 11 and the auxiliary plate 12, which are described in detail, are fixed to each other by a fixing tool 13 such as a rivet and integrated to form a mounting hardware 1. Can be obtained. In addition to the above, the main plate 11 and the auxiliary plate 12 may be fixed by screwing with a general bolt and nut. Alternatively, a burring process may be performed on the joint portion at the time of molding in advance. It may be based on the mode of fitting and fixing. Anyway, it is preferable that it is a joining method which can attach and detach both metal members as needed at the construction site.

  As shown in FIG. 3 (FIG. 10), the mounting hardware 1 (1 </ b> A) is configured such that the protruding flat plate portion 121 of the auxiliary plate 12 is joined to the flat plate portion 111 of the main body plate 11 through the protrusion 124 (124 </ b> A). However, by this, the surface of the protruding flat plate portion 121 is arranged at a position separated from the surface of the flat plate portion 111 of the main body plate 11 by a distance h in the vertical direction. Thereby, in the attachment hardware 1, an appropriate level | step difference (distance h) is ensured in the surface by the side which becomes a joining surface with the ALC panel 2. FIG. In the ALC panel mounting structure 10 as shown in FIG. 7, the size of the step (distance h) is set to the thickness of the angle member 3 on the housing side sandwiched between the mounting hardware 1 and the back surface of the ALC panel 2, and approximately The stability of the ALC panel mounting structure 10 can be sufficiently increased by setting the same size.

  As another embodiment of the mounting hardware, an embodiment using the auxiliary plate 12A shown in FIG. 9 in place of the auxiliary plate 12 can be cited as an example of another preferable embodiment of the mounting hardware of the present invention. . In this embodiment, similarly to the mounting hardware 1 provided with the auxiliary plate 12, an appropriate step (distance h) is secured on the surface to be a joint surface with the ALC panel 2, and the ALC panel is mounted. The stability of the structure 10 can be sufficiently increased.

  Further, the mounting hardware is likely to be distorted and deformed starting from the vicinity of the outer edge of the long hole 113 of the main body plate 11 during use, in which a strong deformation force is applied unevenly to each part. As shown in FIG. 10, the tip of the ridge 124 </ b> A, which is a wall-shaped protrusion, contacts the ridge 124 </ b> A from below in the vicinity of the outer edge of the long hole 113 of the main body plate 11. By using the mounting hardware 1A configured to support the contact portion, the strength of the integrated mounting hardware can be remarkably improved, and the above-described distortion and deformation can be prevented more reliably. it can.

  Further, as shown in FIG. 3, in the mounting hardware 1, the length in the vertical direction (Y direction shown in FIG. 5) of the protruding flat plate portion 121 of the auxiliary plate 12 is a combination target when the mounting hardware 1 is used. The main body plate 11 is formed to be shorter than the length in the same direction. Therefore, in the mounting hardware 1, a partial area near one end in the Y direction of the main body plate 11 is an area where the protruding flat plate 121 is not disposed on the main body plate 11 (see FIG. 2). In this case, it is preferable that one end portion of the main body plate 11 in the Y direction is fixed so that the end portion of the protruding flat plate portion 121 and the end portion of the main body plate 11 are flush with each other. The length in the Y direction of the auxiliary rib portion 122 is preferably the same as the length in the same direction of the rib portion 112 of the main body plate 11 to be combined.

  The lateral width (X direction shown in FIG. 5) of the protruding flat plate portion 121 of the auxiliary plate 12 is made shorter than the same width of the main body plate 11, and the center line in the Y direction is overlapped and arranged. It is preferable. Thereby, the unnecessary interference with the level | step-difference part of a construction location and the protrusion flat plate part 121 can be avoided at the time of attachment of an ALC panel. Details of the mounting method of the ALC panel will be described later.

  The mounting hardware 1 has a corner portion C (FIG. 5) that is substantially perpendicular to the periphery of the boundary portion between the tip end side portion of the protruding flat plate portion 121 in the Y direction and the region where the protruding flat plate portion 121 does not exist on the main body plate 11. Reference) is formed. The corner portion C is formed so as to be engageable with a right-angle portion of the engagement object. Specifically, it functions as a receiving portion that can be engaged with a right-angle portion of an engagement object such as the angle member 3. Such a receiving portion is intimately engaged with the angle member 3, thereby further improving the stability of joining between the ALC panel 2 and the mounting hardware 1 (see FIG. 7).

<Mounting hardware assembly kit>
The mounting hardware 1 of the present invention can also be used as a mounting hardware assembly kit that is a set of assembly kits in a separated state before the main body plate 11 and the auxiliary plate 12 are integrated.

  For example, the mounting hardware 1 can be used in a state of being integrated in advance as shown in FIGS. 1 to 3 and carried into the construction site of the ALC panel 2. It is also possible to carry an assembly kit made up of such parts before integration into the construction site and attach the ALC panel 2 using this kit. In this case, either the step of assembling the mounting hardware 1 by assembling the mounting hardware assembly kit in the required combination, or the step of mounting the ALC panel 2 on the mounting hardware 1 thus assembled, Is also performed at the construction site of the ALC panel 2.

  In particular, when the level difference between the ALC panel attachment points, that is, the thickness of the angle material sandwiched between the ALC panel 2 and the attachment hardware 1 varies depending on the attachment points even within the same construction site, the use mode as an assembly kit is more effective. It is. Specifically, a mounting bracket assembly kit including a single type of main body plate 11 and a plurality of types of auxiliary plates 12 is carried into the construction site, and the auxiliary plates having different shapes that can correspond to each of the above different steps. By assembling the mounting hardware 1 while appropriately selecting 12, it is possible to quickly and flexibly obtain the necessary number of multiple types of mounting hardware 1 at the construction site.

<Lightweight cellular concrete panel mounting structure and mounting method>
(Lightweight cellular concrete panel mounting structure)
As shown in FIGS. 6 and 7, in the ALC panel mounting structure 10 according to the present invention, the ALC panel 2 is fixed to the building frame 5 via the angle member 3 by the mounting hardware 1. More specifically, the surface of the protruding flat plate portion 121 of the mounting hardware 1 is in contact with the back surface of the ALC panel 2, and the angle member 3 is sandwiched between the surface of the main body plate 11 and the back surface of the ALC panel 2. The anchor bolt 4 inserted through the long hole 113 and the notch slit 123 (see FIGS. 1 and 2) is joined to the embedded anchor 21 embedded in the ALC panel 2.

(How to install lightweight cellular concrete panels)
Finally, an attachment method for forming the ALC panel attachment structure 10 will be described. In order to form the ALC panel mounting structure 10 using the mounting hardware 1, first, as shown in FIG. 6A, the protruding flat plate portion 121 of the mounting hardware 1 so that the metal and the angle do not interfere when the panel is installed. Temporarily fix the tip on the side of the region where no is present in the state opposite to the sandwiched angle member 3. Then, as shown in FIG. 6B, the anchor bolt 4 is loosened, the mounting hardware 1 is rotated 180 °, and the above-described corner portion C (see FIG. 5) becomes the step between the angle member 3 and the ALC panel 2. In this state, the anchor bolt 4 is tightened to complete the fixing.

  For example, in the case where the conventionally used Inazuma plate 8 is used as a mounting hardware, when the ALC panel is mounted, the position of the embedded anchor 21 is assumed to be close to the end side of the ALC panel 2. If there is an error in the position, it will be close to the tip of the conventional angle, so that the portion where the above ALC panel mounting position is formed interferes with the insertion position of the anchor bolt 4 and mounting is difficult. However, in the mounting hardware 1, the error can be absorbed by the long hole 113 formed in the main body plate without a step.

  Further, as described above, the mounting hardware 1 is rotated by 180 ° after being temporarily fixed, and when the corner portion C is engaged with the step at the mounting position, the width of the protruding flat plate portion 121 in the X direction is set to the main body plate 11. By making the shape shorter than the same width and arranging it in a part from the center, unnecessary interference between the stepped portion of the construction site and the protruding flat plate portion 121 during the rotation can be avoided. .

  In addition, the mounting hardware 1 is different from the Inazuma plate 8 in that the corner portion C is formed so as to form a substantially right-angled engagement shape in a side view, so that the mounting hardware 1 is rotated by 180 °. Then, after the corner portion C is engaged with the step at the mounting location, it is possible to avoid the joint rotation of the anchor bolt 4 and the mounting hardware 1 when the anchor bolt 4 is tightened.
