Description

  The present invention relates to a structure for attaching an ALC (lightweight cellular concrete) wall panel to a building frame.

  As a structure for attaching an ALC wall panel to a building frame, the structure shown in FIG. 10 of Patent Document 1 is known. That is, as shown in FIG. 14 of the present application drawing, the upper panel 104a and the lower panel 104b are made by using a member divided into three parts of a lightning plate 121, a plate-like member 108 and a self-weight receiving member 109 and a ruler angle 103. 112 is a structure attached to 112. The upper panel 104a is mounted on the weight receiving member 109, and a lightning plate 121 that is hooked on the ruler angle 103 is fixed to the anchor 113 embedded in the upper panel 104a with a bolt 106. The lower panel 104b is attached by fixing a plate-like member 108 hooked between the weight receiving member 109 and the ruler angle 103 to an anchor 113 embedded in the lower panel 104b with a bolt 106.

This mounting structure easily fixes the ALC wall panel 104 to the beam 112 even when the anchor 113 is embedded or the upper panel 104a or the lower panel 104b is displaced from the normal position, for example, less than 6 mm. be able to. That is, the relative mounting position of the lightning plate 121 or the weight receiving member 109 is adjusted, or the plate member 108 is moved in the width direction in the gap between the weight receiving member 109 and the plate member 108 inserted therein. For example, the anchor 113 can be easily aligned with the three members 108, 109, 121 when the panel is attached.
JP 2000-73481 A

  However, the burying position of the anchor 113 may be greatly deviated to the extent that the above mounting structure cannot cope. That is, the anchor 113 is fastened by welding or engagement to a reinforcing bar (not shown) that is also embedded in each panel 104a, 104b in order to increase the strength against pulling out. Since this reinforcing steel bar is loosened by the flow of the slurry at the time of manufacturing the panel, the embedded position of the anchor 113 tightly coupled thereto may be displaced from the normal position by, for example, 6 mm or more. Even if the deviation is within an allowable range for the panel, if the deviation occurs in the upper layer panel 104a in the upward direction as shown in FIG. 15B from the normal position in FIG. 15A, the upper panel 104a. In some cases, the lower part of the lightning plate 121 for attachment engages with the standing piece of the ruler angle 103, and the part of the lightning plate 121 that is fixed by welding may be reduced. Even if the displacement of the anchor 113 is less than 6 mm, if the displacement overlaps with the displacement of the mounting position of the upper panel 104a in the same upward direction, the same problem as described above occurs.

  Further, when the displacement of the anchor 113 is shifted downward in the lower layer panel 104b as shown in FIG. 15 (b) from the normal position in FIG. 15 (a), the plate member 108 for attaching the lower layer panel 104b becomes the ruler. The hook allowance b protruding above between the angle 103 and the rear edge of the horizontal piece of the self-weight receiving member 109 may become small.

  Therefore, the problem of the present invention is that even if the embedment position of the embedment anchor or the mounting position of the ALC wall panel is deviated from the normal position, the amount of the lightning plate or plate member and the portion to be fixed by welding are sufficient. An object of the present invention is to provide an attachment structure that is secured and can attach an ALC wall panel to a building frame with sufficient strength.

[Welding base hardware]
Although it does not specifically limit as a shape of the welding plate part of a welding base metal object, A disk, a square plate, etc. can be illustrated. The dimension of the weld plate is not particularly limited, but if it is too small, the adjustment width becomes narrow, and if it is too large, it becomes waste because it becomes heavy, so the vertical dimension is preferably 100 to 200 mm. It is preferably 20 to 100 mm larger than the lateral dimension of the lightning plate or plate member to be welded. The thickness of the weld plate portion is preferably 6 to 12 mm. This thickness is preferably 6 mm or more as a thickness that does not cause harmful distortion even if the mounting bracket is welded, and even if this thickness is more than 12 mm, an improvement in strength on mounting cannot be expected. This is to become an economy.

Sufficient room for welding and a portion to be welded are secured, and the ALC wall panel can be attached to the building frame with sufficient strength.

  The embedded threaded portion 17 of the welding base metal 15 made up of the welded plate portion 16 and the embedded threaded portion 17 projecting from the back surface thereof is engaged with the threaded portion 10 of the embedded anchor 8 at the upper part of the lower ALC wall panel 1b. The welding plate portion 16 is attached to the panel wall surface 2 on the indoor side of the ALC wall panel 1b by screwing. Then, the ALC wall panel 1b is installed, and the front surface of the ruler angle 12 fixed to the building housing 11 and the rear edge of the horizontal piece 20 of the weight receiving member 18 fixed to the ruler angle 12 are mounted on the weld plate portion 16 thereof. The plate-like member 21 that is slidable between the two is adjusted in position and fixed by welding.

  Also, the embedded threaded portion 17 of the welding base hardware 15 comprising the welded plate portion 16 and the embedded threaded portion 17 protruding from the back surface thereof is engaged with the threaded portion 10 of the embedded anchor 8 at the lower part of the upper ALC wall panel 1a. Are screwed together so that the weld plate portion 16 is attached to the panel wall surface 2 on the indoor side of the ALC wall panel 1a. And in the state where the lower end small end surface of the ALC wall panel 1a is placed on the horizontal piece 20 of the weight receiving member 18 and the lower half of the lightning plate 22 is engaged with the vertical piece 14 of the ruler angle 12, The upper half of the lightning plate 22 is positioned and fixed to the upper welding plate 16 by welding.

  As shown in FIGS. 1 to 7, the first embodiment has a lower part of the upper layer (upper floor in this example) of the ALC wall panel 1 a and an upper part of the lower layer (lower floor of the example) ALC wall panel 1 b. The present invention relates to a structure to be attached to a steel beam as a building frame 11 between layers.

  The two ALC wall panels 1a and 1b are general ones in which a panel wall surface 2 on the indoor side and a panel wall surface 3 on the outdoor side form a vertically long rectangle. Each ALC wall panel 1a and 1b has a reinforcing reinforcing bar 4 and An embedded anchor 8 tightly connected to the reinforcing steel bar 4 is embedded. The reinforcing reinforcing bars 4 are arranged by arranging two frames, which are formed by welding a main reinforcing bar 5 extending in the longitudinal direction and a secondary reinforcing bar 6 extending in the width direction at a predetermined interval, and a spacer 7 is bridged between both frames. It is formed into a cage shape by welding.

The embedded anchor 8 is not particularly limited, and for example, any embedded anchor (insert metal fitting) described in Japanese Patent Application Laid-Open No. 10-72872 and Japanese Patent Application Laid-Open No. 12-54508 may be used. it can.
The embedded anchor 8 illustrated in FIG. 1, FIG. 3, etc. is composed of a pedestal portion 9 that is fastened to the four main bars 5 by welding and a screwed portion 10 by a nut that is welded and fixed to the pedestal portion 9. It is.
The embedded anchor 8 illustrated in FIG. 4A is composed of a pedestal portion 9 that is fastened to a single auxiliary muscle 6 by welding, and a screwed portion 10 that is a nut fixed to the pedestal portion 9 by welding. It is.
The embedded anchor 8 illustrated in FIG. 4B is composed of a pedestal portion 9 that is fastened to the two main bars 5 by welding and a screwed portion 10 that is a nut fixed to the pedestal portion 9 by welding. is there.
However, as described above, it is preferable in terms of proof stress that two or more reinforcing bars 4 are tightly coupled. Further, the ALC cover (depth) dimension from the panel wall surface 3 to the pedestal portion 9 of the ALC wall panel is 5 mm or more.

  Since the reinforcing reinforcing bars 4 are loosened by the flow of the slurry at the time of manufacturing the panel, the embedded position of the embedded anchor 8 tightly coupled thereto may be shifted from the normal position by, for example, 6 mm or more (after slurry hardening).

Now, in addition to the embedded anchor 8, the following mounting brackets are used to attach both ALC wall panels 1a, 1b to a horizontally installed building frame (steel beam in this example) 11.
A welding base metal 15 including a welding plate portion 16 and an embedded screwing portion 17 protruding from the back surface thereof.

A self-weight receiving member 18 that is fixed to the building frame 11 by being welded to the front side of the vertical piece 14 of the ruler angle 12 on the left and right sides, and is fixed to the building frame 11 and has a substantially horizontal horizontal piece 20 extending forward.
A plate-like member 21 that is slidably inserted between the building housing 11 and the rear edge of the horizontal piece 20 of the weight receiving member 18 and between the left and right vertical pieces 19. The plate-like member 21 has a width of, for example, 75 mm and a vertical length of, for example, 150 mm.
A lightning plate 22 welded and fixed to the welding plate portion 16 while being hooked on the vertical piece 14 of the ruler angle 12. The lightning plate 22 has a width of, for example, 75 mm and a vertical length of, for example, 95 mm. The lightning plate 22 in the illustrated example has a long hole, but this is because a conventional lightning plate with a long hole (FIGS. 14 and 15) is used as it is. Do not use. Therefore, a lightning plate without a long hole may be used.

  The welding base metal 15 is formed by integrally forming a welding plate portion 16 made of a disc having a diameter of 120 mm and a thickness of 6 mm, and an embedded screwing portion 17 made of a male screw. As shown in FIG. 3B, the weld plate portion 16 and the embedded screw portion 17 may be separately formed and joined. Then, the embedded threaded portion 17 of the welding base metal 15 is threadedly engaged with the threaded portion 10 of the embedded anchor 8, and the welding plate portion 16 is attached to the panel wall surface 2 of the ALC wall panel 1. In this example, the welding plate part 16 is accommodated in the drilling part 23 provided in the panel wall surface 2 of each ALC wall panel 1a, 1b (following the drilling part 23 of the panel wall surface 2), and the welding plate part 16 welding surfaces and the general part of the panel wall surface 2 are substantially the same surface.

  An embedded threaded portion 17 of a welding base metal 15 is threadedly engaged with the threaded portion 10 of the embedded anchor 8 at the upper part of the lower ALC wall panel 1b, and the welding plate portion 16 is attached to the panel wall surface of the ALC wall panel 1b. ing. Then, an ALC wall panel is installed (the attachment structure at the lower part is the same as that of the upper ALC wall panel 1a), and the front surface of the ruler angle 12 and the horizontal piece 20 of the weight receiving member 18 are formed on the welding plate portion 16. The plate-like member 21 hooked between the rear edge is adjusted in position and fixed by welding.

  In addition, the embedded threaded portion 17 of the welding base metal 15 is threadedly engaged with the threaded portion 10 of the embedded anchor 8 at the lower part of the upper ALC wall panel 1a, and the welding plate portion 16 is the panel wall surface of the ALC wall panel 1a. It follows. Then, the welding plate is mounted in a state where the lower end edge of the ALC wall panel 1 a is placed on the horizontal piece 20 of the weight receiving member 18 and the lower half of the lightning plate 22 is engaged with the vertical piece 14 of the ruler angle 12. The position of the upper half of the lightning plate 22 is adjusted to the part 16 by welding.

  Both ALC wall panels 1a and 1b are attached to the building housing 11 by a method including the following steps. The ALC wall panels 1a and 1b are preliminarily embedded with reinforcing reinforcing bars 4 and embedded anchors 8 tightly connected to the reinforcing reinforcing bars 4, and the embedded position of the embedded anchor 8 is, for example, 6 mm from the normal position as described above. There may be a deviation.

(1) The ruler angle 12 is welded and fixed to the steel beam as the building frame 11, and the self-weight receiving member 18 is fixed to the ruler angle 12 by welding.

(2) The embedded screwed portion 17 of the welding base metal 15 is screwed into the screwed portion 10 of the embedded anchor 8 of the lower ALC wall panel 1b, and the weld plate portion 16 is connected to the panel wall surface of the lower ALC wall panel 1b. Attached to the second counterbore 23.

(3) A plate-like member in which the lower ALC wall panel 1b is installed, and is slidably moved up and down between the front surface of the ruler angle 12 and the rear edge of the horizontal piece 20 of the weight receiving member 18 in the welding plate portion 16. 21 is welded by adjusting the position. At this time, as shown in FIG. 7, if the embedded position of the embedded anchor 8 is greatly shifted downward (for example, 6 mm or more) from the normal position in FIG. Both parts 16 are also greatly displaced downward. Even if the burying position deviation of the burying anchor 8 is less than 6 mm, the same is true if the deviation overlaps with the deviation of the mounting position of the ALC wall panel 1b. Even in such a case, as shown in FIG. 7B, the welding plate portion 16 is not only removed from contact with the plate-like member 21 without shifting the plate-like member 21 synchronously downward. Therefore, the welding plate portion 16 and the plate-like member 21 can be fixed by welding. For this reason, the hook allowance b in which the upper part of the plate-like member 21 protrudes above between the ruler angle 12 and the rear edge of the horizontal piece 20 of the weight receiving member 18 is sufficiently secured.

(4) The embedded threaded portion 17 of the welding base metal 15 is screwed into the threaded portion 10 of the embedded anchor 8 of the upper ALC wall panel 1a, and the weld plate portion 16 is connected to the panel wall surface of the upper ALC wall panel 1a. Attached to the second counterbore 23.

(5) The lightning bolt is placed on the upper weld plate 16 with the lower end edge of the upper ALC wall panel 1a placed on the weight receiving member 18 and the lower half of the lightning plate 22 hooked on the ruler angle 12. The position of the upper half of the plate 22 is adjusted and fixed by welding. At this time, as shown in FIG. 7, if the embedded position of the embedded anchor 8 is greatly shifted upward (for example, 6 mm or more) from the normal position in FIG. Both parts 16 are also greatly displaced upward. Even if the displacement of the embedded anchor 8 is less than 6 mm, the same is true if the displacement overlaps with the displacement of the mounting position of the ALC wall panel 1b. Even in such a case, the welding plate portion 16 has a size that does not remove the contact with the lightning plate 22 without shifting the lightning plate 22 in synchronization with the upward direction. And the lightning plate 22 can be fixed by welding. For this reason, the hook allowance a with which the lower half part of the lightning plate 22 engages with the vertical piece 14 of the ruler angle 12 is sufficiently secured.

  Regardless of the order of the above (3) and (5), either may be performed first. Further, (2) is performed before (3) and (4) is performed before (5), but the order of (2) and (4) is not limited.
