Description

  The present technology mainly relates to a mounting structure and a mounting method of a wall panel to a concrete part on a frame side such as a beam, a column, a slab, or a wall of a RC or SRC building.

  A general example in which, for example, an ALC wall panel is attached to the upper part of the slab concrete floor will be described with reference to FIGS. 5A and 5B are diagrams showing a connection portion between a lower portion of a wall panel and a housing according to a conventional example, in which FIG. 5A is a sectional view and FIG. 5B is an interior view. In this example, an example in which an ALC wall panel is used as the wall panel will be described. As shown in FIG. 5, a concrete rising portion 19 is provided at an upper portion of the slab concrete floor 18, and an embedded angle 20 for attaching a base angle 21 is provided in the same portion. The ground angle 21 is fixed to the concrete rising portion 19 by being welded to the embedded angle 20. The wall panel 17 is attached and fixed to the base angle 21 by an attachment fastener composed of a bolt 22, an anchor steel rod 23, and a Inazuma hardware 24. Incidentally, 25 is a liner, and 26 is a sealing material.

  A technique similar to the above technique is also disclosed in Non-Patent Document 1. In addition, there is a technique capable of adjusting the height when a wall panel is attached to the concrete frame (see, for example, Patent Document 1). There is also a technique for attaching a partition wall panel to which wind pressure does not act on the frame concrete without exposing the mounting hardware (see, for example, Patent Document 2).

Architectural Institute of Japan, “Building Construction Standard Specification / Explanation JASS21 ALC Panel Construction 2005”, p. 42 “Explanation Figure 3.3 Example of Rocking Construction in Reinforced Concrete” JP-A-11-124937 JP-A-2005-48492

When a wall panel is attached to the upper part of a slab concrete floor of a building, generally, as shown in FIG. 5 or Non-Patent Document 1, the base angle for attaching the wall panel, hardware such as attachment fasteners are on the front side or back side of the panel. Exposed to either.
For this reason, the hardware may be an obstacle to the finishing work, and the money may protrude from the finished surface and look bad.
Further, if hardware protrudes from the wall panel, there is a risk of injury by catching a part of the body, so further improvement in safety is also required.

The first object of the present invention is not to expose the hardware for mounting the wall panel on either the front side or the back side of the wall panel.
Next, the technique of Patent Document 1 has a problem that the height of the raised metal fitting is determined by the shape of the raised metal fitting, and it is difficult to finely adjust the height.

The second object of the present invention is to easily and accurately adjust the height of the wall panel (the distance from the concrete frame).
In addition, the technique of Patent Document 1 has a problem that the shape of the mounting hardware is complicated and the number of parts is large, which is disadvantageous economically.

The third object of the present invention is to provide a low-cost and economical mounting method by simplifying the shape of the mounting hardware and reducing the number of parts.
Furthermore, in Patent Document 2, when a concrete nail is driven, defects such as cracks and chips are likely to occur in the concrete portion, so the reliability in the direction perpendicular to the longitudinal direction of the concrete nail is low, and shearing is repeated on the concrete nail. For reasons such as unreliability of metal fatigue failure when a load is applied and the shear strength of the concrete nail itself being small, there is a problem that it is difficult to use for an outer wall panel on which wind pressure acts as it is. In addition, this technique has a problem that the height of the wall panel from the frame concrete can hardly be adjusted.

  A fourth object of the present invention is to provide a mounting structure with high shear resistance that can be used even at a site where a large horizontal force such as wind pressure acts, such as an outer wall.

  In other words, the object of the present invention is to make the wall panel easy, reliable, accurate, low cost, and highly shear resistant without exposing the hardware for mounting the wall panel on either the front side or the back side of the wall panel. It is to be attached to the concrete on the building side of the building with force.

In order to achieve the above object, the present invention has the following means.
(1)
A wall panel mounting structure to a building in which a wall panel is mounted on a slab concrete floor, and a rod-shaped member is inserted into a long hole provided in the in-plane direction of the wall panel from the edge of the wall panel. The slab concrete floor has a pedestal member threadedly engaged with an upper bar member fixed to the slab concrete floor, and a through member is interposed between the bar member and the pedestal member. The end of the bar-shaped member that is not inserted into the wall panel is placed and fixed on the through member, and the base member restrains the movement of the wall panel toward the slab concrete floor. mounting structure for wall panel characterized by comprising Te.

(2)
The mounting structure for a wall panel according to (1), wherein the base member and the through member are fixed by welding.

(3)
A method of attaching a wall panel to a building, the step of inserting a rod-like member into a long hole provided in the in-plane direction of the wall panel from the edge of the wall panel, and the upper side of the slab concrete floor Screwing the pedestal member onto the floor bar member fixed to the slab concrete floor and disposing the through member on the pedestal member on the upper side of the slab concrete floor; and attaching the wall member to the wall panel of the bar member Placing the end of the non-inserted side on the threading member; placing the panel at an arbitrary distance from the upper end of the slab concrete floor by the pedestal member; and the threading member and the rod-shaped member A method for attaching a wall panel, comprising: fixing a member by welding.

(4)
The mounting method of the wall panel according to (3), wherein the base member and the through member are fixed by welding.

According to the above configuration and method, the hardware for mounting the wall panel is not exposed on either the front side or the back side of the wall panel. For this reason, the design of the wall panel can be improved both in the appearance and in the interior. Moreover, it becomes easy to insert a liner by using a threading member, and workability is improved. Further, since the base member are to be screwed, by rotating the base member, the height of the panel can be adjusted easily and precisely. Furthermore, it is also suitable for a portion such as an outer wall where a large horizontal force such as wind pressure acts. In addition, the mounting hardware is economical because it has a relatively simple shape with a small number of parts.

  Embodiments of the present invention will be specifically described with reference to the drawings. In addition, as a structure of the attachment part of a wall panel, in the following description, only the lower structure of a wall panel is illustrated and demonstrated. Although not shown in the figure, some restraining means for the force in the out-of-plane direction of the wall panel is provided at one or more of the side part and the upper part of the wall panel. In addition, when the mounting structure of the present embodiment is applied to the side surface of the wall panel, some restraining means for the force in the out-of-plane direction of the wall panel is provided at one or more of the other side, upper part, and lower part. It will be provided.

The configuration of this embodiment will be described with reference to the drawings. FIGS. 1A and 1B are explanatory views of attaching a wall panel to frame concrete in the present embodiment, in which FIG. 1A is a lower elevation sectional view, FIG. 1B is a lower plan sectional view, and FIG. 1C is a lower interior view.
As shown in FIG. 1, the attachment structure of the lower part of the wall panel to the building of this embodiment is a structure which fixes the wall panel 1 and the slab concrete floor 3. As shown in FIG.

  The wall panel 1 is provided with a long hole portion 2 in the in-plane direction from the lower edge of the wall panel 1. A rod-like member 4 is inserted into the long hole portion 2 so as to protrude toward the slab concrete floor 3 side. The rod-like member 4 is composed of a rod-like portion 4a inserted into the wall panel 1 and a planar portion 4b formed at the end of the rod-like portion 4a on the side not inserted into the wall panel 1.

  On the slab concrete floor 3, a post-installed anchor 5 is embedded in a portion facing the wall panel 1, and a long bolt (floor bar-like member) 6 is screwed and fixed to the post-constructed anchor 5 so as to protrude to the wall panel 1 side. Is done. A rising portion 9 is formed integrally with the slab concrete floor 3 around the long bolt 6. The rising portion 9 can be a post-packed mortar or the like, and the rising portion 9 may be formed before or after the wall panel 1 is attached. A base member 7 having a planar shape portion 7 a is screwed and fixed to the long bolt 6 at the end of the long bolt 6 on the wall panel 1 side. Thereby, the movement to the slab concrete floor 3 side of the wall panel 1 installed through the threading member 12 and the liner 13 is restrained.

In the present embodiment, the threading member 12 is provided between the planar shape portion 4 b of the rod-shaped member 4 and the planar shape portion 7 a of the base member 7. In the present embodiment, the shape of the through member 12 is L-shaped such as angle steel. A liner 13 is installed between the wall panel 1 and the through member 12. In addition to adjusting the panel height, the liner 13 provides a gap between the lower part of the panel and the threading member 12. Therefore, when the panel supported at two points is locked (rotated) during an earthquake or the like, Can be prevented from coming into contact with the threading member 12 and missing the corners of the panel.
In addition, as shown in FIG. 1A, a sealing material 11 is provided between the wall panel 1 and the rising portion 9.

Next, a method for attaching the wall panel 1 will be described.
First, the rod-like member 4 is inserted into the long hole portion 2 provided in the in-plane direction of the wall panel 1 from the small edge of the wall panel 1. On the other hand, a rising portion 9 is formed between the slab concrete floor 3 and the wall panel 1.
Next, the threading member 12 is disposed in the horizontal shape on the planar shape portion 7a of the plurality of pedestal members 7 provided by adjusting the level on the slab concrete floor 3 side. And fixed by welding.

Next, as shown in FIG. 1B, the liner 13 is installed at a predetermined position on the threading member 12. The position of the liner 13 is preferably one place near the center of the panel width as in the present embodiment, or two places near both side edges of the wall panel 1 in the panel width direction.
Next, the wall panel 1 to which the rod-like member 4 is attached is placed on the liner 13, and when the horizontal position of the wall panel 1 is determined, the planar shape portion 4 b is welded and fixed to the member 12. When the liner 13 is not installed on the through member 12, the liner 13 may be inserted between the planar shape portion 4 b and the wall panel 1.

  As described above, in the present embodiment, the through member 12 is provided between the rod-like member 4 and the base member 7. If the through member 12 is not provided, the position of the planar shape portion 7a and the planar shape portion 4b will be misaligned if the horizontal position accuracy of the planar shape portion 7a or the planar shape portion 4b is not good, and a sufficient welding margin is secured. There was something I couldn't do.

In the present embodiment, since the through member 12 having a large area is provided at a predetermined position on the planar shape portion 7a, even if the rod-like member 4 has a horizontal position error (positional deviation), the planar shape portion 4b can be securely fixed to the through member 12 by welding.
Moreover, the workability | operativity for inserting the liner 13 improves by providing the threading member 12. FIG. That is, when the through member 12 is not provided, it is necessary to insert into the very narrow space between the planar shape portion 4b and the wall panel 1, and workability is poor. On the other hand, in this embodiment, since the liner 13 is installed in a wide space between the wall panel 1 and the through member 12, workability is good.

  In addition, when finely adjusting the height in the present embodiment, the wall panel 1 can be floated by directly inserting a bar or the like at an arbitrary position between the through member 12 and the wall panel 1. The overlap liner 13 can be easily inserted, and the working efficiency is good. On the other hand, it is assumed that a liner is provided between the rod-like member 4 and the pedestal member 7 without providing the threading member 12, and the height of the wall panel 1 after the wall panel 1 is once placed on the planar portion 7a via the liner. When making fine adjustments, the wall panel 1 must be lifted, but because the dimension between the wall panel 1 and the slab concrete floor 3 is large, the height on the slab concrete floor 3 is about the same as the rising portion 9. Since a member such as a square member was inserted and a bar or the like was inserted between the member and the wall panel 1 to float the panel, workability was poor. In this embodiment, this point is improved.

  In this embodiment, the base member 7 and the through member 12 are fixed by welding, but the present invention is not limited to this. For example, a modification as shown in FIG. 2 may be used. FIGS. 2A and 2B are explanatory views of attaching the wall panel to the frame concrete in the modified example of the present embodiment, wherein FIG. 2A is a lower vertical sectional view, FIG. 2B is a lower plan sectional view, and FIG. 2C is a lower interior view. .

  In the modification shown in FIG. 2, the base member 7 and the through member 12 are not fixed by welding. That is, by passing the long bolt 6 through a hole (not shown) provided in the threading member 12 and sandwiching the upper and lower sides of the hole by the upper nut 8 and the base member 7 as the lower nut, the threading member 12 is fixed to the base member. 7 fixed on top. Thus, if it is set as the structure fixed by screwing without requiring welding fixation, height can be adjusted any number of times by rotating the base member 7 and the upper nut 8. FIG. This is convenient when the height of the threading member 12 is once determined and then the height is readjusted.

  Further, if the upper and lower sides of the hole penetrating through the through member 12 are clamped and fixed with nuts as in the present modification, it is compared with the configuration in which the long bolt 6 is not penetrated through the through member 12 as in the above-described embodiment. And the movable range of the base member 7 becomes wide. For this reason, the range of height adjustment of the base member 7 is widened, and the height of the through member 12 fixed on the base member 7 can be made more desirable.

[Other Embodiments]
The configuration of another embodiment will be described with reference to the drawings. FIGS. 3A and 3B are explanatory views of attaching wall panels to frame concrete according to another embodiment, wherein FIG. 3A is a lower elevation sectional view, FIG. 3B is a lower plan sectional view, and FIG. 3C is a lower interior view.

In the configuration of the above-described embodiment, the shape of the through member 12 is an L shape, but is not limited thereto. For example, as shown in FIG. 3, a plate-like member such as a flat bar may be used.
Further, in the configuration of the above-described embodiment, the liner 13 has been installed on the through member 12 or the planar shape portion 4b prior to the panel 1 attachment. The panel 1 that has been attached may be placed on the threading member 12 via the liner 13 and the liner 13 and the planar shape portion 4b.
Moreover, in other embodiment, although the base member 7 and the penetration member 12 were fixed by welding, it is not restricted to this. For example, a modification as shown in FIG. 4 may be used. 4A and 4B are explanatory views of attaching the wall panel to the frame concrete according to the modified example of the other embodiment, in which FIG. 4A is a lower elevation sectional view, FIG. 4B is a lower plan sectional view, and FIG. is there.

  In the modification shown in FIG. 4, the base member 7 and the through member 12 are not fixed by welding. That is, by passing the long bolt 6 through a hole (not shown) provided in the threading member 12 and sandwiching the upper and lower sides of the hole by the upper nut 8 and the base member 7 as the lower nut, the threading member 12 is fixed to the base member. 7 fixed on top. Thus, if it is set as the structure fixed by screwing without requiring welding fixation, height can be adjusted any number of times by rotating the base member 7 and the upper nut 8. FIG. This is convenient when the height of the threading member 12 is once determined and then the height is readjusted.

  Further, if the upper and lower sides of the hole penetrated through the threading member 12 are clamped and fixed by nuts as in this modification, the long bolt 6 is not allowed to penetrate the threaded member 12 as in the other embodiments described above. In comparison, the movable range of the base member 7 is widened. For this reason, the range of height adjustment of the base member 7 is widened, and the height of the through member 12 fixed on the base member 7 can be made more desirable.
