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. The present invention can be suitably applied to concrete wall panels such as PC plates, ALC plates, and extrusion-molded plates.

  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. 2A and 2B 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. 2A is a sectional view and FIG. 2B 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. 2, 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).

The 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 Structure” 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. 3 or Non-Patent Document 1, the base angle for attaching the wall panel, and hardware such as attachment fasteners are on the front side or the 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 it is difficult to finely adjust the height because the unit of the height adjustment dimension depends on the thickness of the plate spacer (round washer).

  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. An object is to provide an attachment structure and an attachment method that can be attached to concrete on the building side of a building with force.

  In order to achieve the above object, the present invention has the following means.

  Do not expose hardware for mounting the wall panel on either the front or 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. Further, if the pedestal member is screwed, the height of the panel can be adjusted easily and accurately by rotating the pedestal member. 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.

  Therefore, without exposing the hardware for mounting the wall panel on either the front side or the back side of the wall panel, the wall panel can be easily and accurately made with high shear resistance to the concrete on the building side of the building. Can be attached.

And

  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-shaped member 4 is composed of a rod-shaped portion 4a inserted into the wall panel 1 and a planar-shaped portion 4b disposed at the end of the rod-shaped portion 4a on the side not inserted into the wall panel 1. The planar shape portion 4b is at an end portion on the side not inserted into the wall panel 1. A pedestal member 7 having a planar shape portion 7a is disposed on a surface that contacts the planar shape portion 4b.

  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 member) 6 is screwed and fixed to the post-constructed anchor 5 so as to protrude toward 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. Further, a base member 7 having a planar shape portion 7a and a female screw 7b is screwed and fixed to an end portion of the long bolt 6 on the wall panel 1 side. This restrains the movement of the wall panel 1 toward the slab concrete floor 3 side.

  Here, the planar shape portion 4 b of the rod-like member 4 on the side not inserted into the wall panel 1 is fixed by welding to the pedestal member 7 on the upper side of the rising portion 9. In FIG. 1, 8 is a welded portion and 11 is a sealing material.

  Next, a method for attaching the wall panel 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 wall panels 1 on the slab concrete floor 3.

  Next, the planar shape portion 4b of the rod-like member 4 attached to the wall panel 1 is placed in contact with the planar shape portion 7a. By rotating the base member 7 in this state, the panel height position of the wall panel 1 (a position away from the upper end of the rising portion 9) is arbitrarily finely adjusted.

  And after determining a panel height position, the wall panel 1 is attached to the upper part of the slab concrete floor 3 via the long volt | bolt 6 and the post-construction anchor 5 by welding and fixing the plane shape part 4b to the plane shape part 7a. Note that a liner 10 may be sandwiched between the wall panel 1 and the planar portion 4b as necessary.

  Next, a sealing material 11 is placed between the wall panel 1 and the concrete rising portion 9.

  When the wall panel 1 is required to withstand a large load such as wind pressure or seismic force, it is possible to withstand a large load by increasing the number of mounting portions. .

  As described above, according to the present invention, the wall panel can be easily and accurately, accurately and inexpensively exposed without exposing the hardware for mounting the wall panel on either the front side or the back side of the wall panel. It can be attached to concrete on the building side of the building with shear resistance.

  Further, by forming the rising portion 9 that abuts and adheres to the slab concrete floor 3 between the pedestal member 7 and the slab concrete floor 3, the support force of the long bolt 6 can be increased and wobble can be prevented. It is preferable to use at least one of a mortar layer and a concrete layer for the rising portion 9.

  Further, a rod-shaped member 4 is formed with a rod-shaped portion 4 a, and the base member 7 is formed with a planar shape portion 7 a. If the size of the planar shape portion 4b is increased to some extent within a range not exceeding the thickness range of the wall panel 1, the weldable range is increased, and welding can be performed more easily.

  The present invention can be applied to concrete structures other than RC structures and SRC structures, for example, slab concrete portions of S structures.
