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 of attaching a wall panel to frame concrete will be described with reference to FIG. 3A and 3B 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. 3A is a sectional view and FIG. 3B 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. 3, the embedded concrete 15 is provided with an embedded plate 15 for attaching the foundation angle 16. The base angle 16 is fixed to the concrete frame 14 by being welded to the embedded plate 15. The wall panel 13 is fixedly attached to the base angle 16 by a mounting fastener composed of a bolt 17, an anchor steel bar 18 and an inner metal fitting 19.

  When attaching an ALC wall panel to frame concrete, a construction method as shown in FIG. 3 is mentioned as a general construction method. In this construction method, first, the base angle 16 is welded and fixed to the embedded plate 15 attached to the concrete frame by welding or the like. Then, the wall panel 13 is attached to the base angle 16 using attachment fasteners such as bolts 17, anchor steel rods 18, and inner metal fittings 19. In FIG. 3, 20 is a liner and 21 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 Structure Installation in Reinforced Concrete” JP 10-2047 A JP-A-2005-48492

  When a wall panel is attached to the building concrete of a building, generally, as shown in Fig. 3 or Non-Patent Document 1, the base angle for attaching the wall panel, hardware such as mounting fasteners is either on the front side or the back side of the panel Exposed to. 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, in the technique of Patent Document 1, since the unit of the height adjustment dimension depends on the thickness of the liner 20, it is difficult to finely adjust the height, or after placing the panel on the foundation or the slab, again. When it is necessary to adjust the height, it is necessary to insert a liner having a desired thickness through the rod-shaped member after removing the panel from the rod-shaped member, which causes a problem that the operation becomes complicated.

  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).

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

  That is, the object of the present invention is to easily and accurately provide a wall panel with a high shear resistance without exposing the hardware for mounting the wall panel on either the front side or the back side of the wall panel. It is providing the attachment structure and attachment method which can be attached to the concrete of the side of a frame.

  As means for achieving the above object, the present invention has the following configuration and method.

(1)
A wall panel mounting structure to a building, wherein a rod-like member is inserted into a long hole provided from a small edge of the wall panel toward an in-plane direction of the wall panel, and the wall panel of the rod-like member A wall panel mounting structure, characterized in that an end portion on the side not inserted into the wall and the concrete frame are integrated and fixed with a hardened material.

(2)

(4)
The wall panel mounting structure according to any one of (1) to (3), wherein at least one of a mortar layer and a concrete layer is provided between the wall panel and the frame concrete.

(5)
A method of attaching a wall panel to a building, wherein a rod-shaped member is inserted into a long hole provided from a small edge of the wall panel toward an in-plane direction of the wall panel; and the wall of the rod-shaped member The wall panel is installed at an arbitrary distance from the housing by a step of contacting the end of the side not inserted into the panel to the concrete and a panel support member that is screwed or welded to the rod-shaped member. A method of attaching a wall panel, comprising: a step; and a step of integrating and fixing the rod-shaped member and the frame concrete with a cured product.

  With 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. Further, the height of the wall panel (the distance from the concrete frame) can be easily and accurately adjusted. Furthermore, it is also suitable for a portion such as an outer wall where a large horizontal force such as wind pressure acts. 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.

  An embodiment of the present invention will be specifically described with reference to the drawings. FIG. 1 is a cross-sectional view showing the outline of a wall panel mounting structure to a concrete frame. 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. Further, 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.

  As shown in FIG. 1 (a), in the wall panel mounting structure of the present embodiment, a rod-shaped member 4 is provided in a long hole portion 2 provided in the in-plane direction of the wall panel 1 from the small edge 1a of the wall panel 1. Has been inserted.

  By constructing in this way, the wall panel can be easily and reliably constructed with high precision and high strength without exposing any hardware for mounting the wall panel on either the front or back side of the wall panel 1. It can be attached to the concrete on the side of the frame, and it can be a neat and clean fit.

  Moreover, as shown to Fig.1 (a), the edge part 4a of the side which is not inserted in the wall panel 1 of the rod-shaped member 4 is contact | abutted to the frame concrete 3, and the circumference | surroundings of the edge part 4a are covered with the hardened | cured material 5. The rod-shaped member 4 and the frame concrete 3 are integrated and fixed with a cured product 5. In this embodiment, as shown in FIG. 1, the cured product 5 is a narrow range around the rod-shaped member 4, but the frame concrete 3 is a floor slab, and a finished mortar layer (cured product) is formed on the entire upper surface of the floor slab. ), The width (size) of the cured product 5 is in a wide range. The cured product 5 may be anything such as mortar, concrete, resin adhesive, etc., as long as it can be molded before curing and does not lose its shape after molding and exhibits the required strength after curing. For example, in the case of mortar, a kneaded mortar in which moisture is suppressed to some extent is suitable.

  By comprising in this way, the rod-shaped member 4 can be fixed to the arbitrary positions on the surface of the concrete frame 3. As a result, there is no need for hardware such as an embedded plate 15 for fixing hardware for attaching the wall panel 1 to the frame concrete 3 side. Therefore, the number of members can be omitted, which is economical. Further, in the conventional construction method in which the receiving material such as the embedded plate 15 is provided in advance on the side of the concrete body 3, it is often difficult to absorb the error when the receiving material position and the wall panel position are greatly deviated. There is no such worry.

  Moreover, as shown in FIG.1 (b), it has the panel support member 6 penetrated by the rod-shaped member 4 between the wall panel 1 and the frame concrete 3. As shown in FIG. Then, the panel support member 6 is brought into contact with the wall panel 1, and the wall panel 1 is moved to the concrete frame 3 side by welding and fixing to the rod-shaped member 4 when the position of the wall panel 1 from the frame concrete structure 3 side is determined. Restrain the movement of Thereby, the movement to the frame concrete 3 side of the wall panel 1 can be restrained easily.

  In FIG. 1B, the rod-like member 4 has a male screw (bolt) on the periphery thereof, the insertion hole of the panel support member 6 has a female screw, and is inserted into the wall panel 1 of the rod-like member 4. It is good also as a structure by which the panel support member 6 is inserted and screwed to the non-side, and the wall panel 1 contact | abuts to the panel support member 6, and the movement to the side of the concrete body 3 of the wall panel 1 is restrained. In this case, the rod-shaped member 4 or the panel support member 6 is rotated, and the panel support member 6 is brought into contact with the wall panel 1, so that the movement of the wall panel 1 toward the frame concrete 3 is restricted. Moreover, the panel support member 6 moves up and down along the rod-shaped member 4 by rotating the panel support member 6. For this reason, the height from the frame concrete 3 of the panel support member 6 can be adjusted accurately.

  A nut can also be used as the panel support member. In this case, when a large stress is expected to be applied from the nut to the panel, it is preferable to provide a plate-like member between the panel 1 and the nut. When a plate-like member having an upper area larger than that of the nut is provided, the plate-like member disperses stress applied to the panel from the nut, so that a more durable structure can be obtained.

  In addition, as shown in FIG. 1C, when the clearance between the wall panel 1 and the frame concrete 3 is large, the mortar that abuts and adheres to the frame concrete 3 side between the wall panel 1 and the frame concrete 3. It has a layer or concrete layer 7. Thereby, the support force of the rod-shaped member 4 can be increased and wobble can be prevented.

  In addition, the attachment part of this embodiment is not restricted to the lower part of a wall panel, but can consider all directions, such as an upper part and a horizontal part. In other words, if the wall panel and the concrete frame are in a facing relationship as shown in FIG. 1, they can be attached in all directions in the building.

  In addition, when the wall panel 1 is required to withstand a large horizontal load such as wind pressure or seismic force, increasing the number of mounting structures allows a large horizontal load without changing the appearance of the wall panel surface. It is possible to withstand.

  Next, attachment of the wall panel will be described.

  FIG. 2 is a state diagram in which the wall panel is attached to the concrete frame, in which (a) is a cross-sectional view and (b) is an interior view.

  When the wall panel 1 is attached to the frame concrete 3, first, the long hole portion 2 provided in the in-plane direction of the wall panel 1 from the small edge 1 a of the wall panel 1 is disposed on the wall panel 1 side of the rod-shaped member 4. Insert one end. Thereby, the moving direction of the rod-shaped member 4 is regulated in the in-plane direction of the wall panel 1 (the vertical direction in the present embodiment).

  Next, the rod-like member 4 having the male screw or the panel support member 6 is rotated while the panel support member 6 is in contact with the wall panel 1. And the edge part 4a of the side which is not inserted in the wall panel 1 of the rod-shaped member 4 is made to contact | abut with the frame concrete 3. FIG.

  Next, the periphery of the end 4a is covered with a cured product 5 such as mortar. Then, the rod-shaped member 4 and the concrete frame 3 are integrated and fixed by the action of the cured product 5.

  In addition, when the clearance between the wall panel 1 and the frame concrete 3 is large, a mortar layer or a concrete layer 7 is formed between the wall panel 1 and the frame concrete 3 so as to contact and adhere to the frame concrete 3. Thereby, the support force of the rod-shaped member 4 is increased and wobble is prevented. In addition, both the mortar layer and the concrete layer may be abutted and fixed.

  Note that when the wall panel 1 rotates relative to the concrete 3 due to an interlayer deformation at the time of an earthquake and the like, the rod-like member 4 rotates around the end on the side in contact with the concrete 3 as shown in FIG. As described above, a space may be provided between the wall panel 1 and the concrete frame 3 and the space may be filled with a material having high followability to deformation, such as a sealing material 8. Moreover, when it is assumed that the wall panel 1 hardly rotates, for example, the upper part of the wall panel 1 can slide, even if mortar or concrete is filled between the wall panel 1 and the frame concrete 3 without a gap. Good.

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