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.

  Conventionally, as shown in FIG. 2, as a method of attaching a wall panel 101 such as an ALC (lightweight cellular concrete) plate to a structural frame 102 of a building, the side surface of the first L-shaped steel 103 that supports the small edge of the ALC plate is There is a method of welding and fixing the rising side surface of the second L-shaped steel 104 fixed to 102 (see, for example, Patent Document 1).

Japanese Patent Application No. 2006-112113

  However, position adjustment work is required when the housing 102 is uneven or has a slope. In this case, a method is used in which the side face of the first L-shaped steel 103 is squeezed to the side face of the rising portion of the second L-shaped steel 104 and the position of the first L-shaped steel 103 is struck and adjusted. The positioning work of the steel 103 was difficult. In addition, when the housing 102 is uneven, the lower surface of the first L-shaped steel 103 and the upper surface of the housing 102 are not flush with each other, so that there is a problem that the first L-shaped steel 103 is difficult to perform rattling positioning. . Further, when the housing 102 has a gradient, if the first L-shaped steel 103 is placed on the housing 102, the first L-shaped steel 103 is inclined in a gradient, so that it is difficult to fix the second L-shaped steel 104 horizontally. There was a problem. In addition, the first L-shaped steel 103 may be distorted during welding, which affects the final level accuracy of the wall panel 101. Further, when the position is adjusted again after being fixed, there is a problem that the work of cutting the welding is necessary, and the position adjusting work is difficult.

  Further, when the second L-shaped steel 104 and the inertia plate 105 are arranged in the vertical direction, the first L-shaped steel 103 cannot be welded to the second L-shaped steel 104 because they interfere with each other. For this reason, the second L-section steel 104 must be disposed so that they do not interfere with each other. In addition, when the wall panel 101 is attached, the spacer 106 is placed between the wall panel 101 and the first L-shaped steel 103. However, if the spacer 106 is not fixed by any means, the spacer 106 is displaced during construction of the wall panel 101. There was a fear. Further, even when fixing, there is a problem that it is necessary to provide a means for fixing separately, which takes time.

  Therefore, an object of the present invention is to efficiently attach the wall panel and the housing.

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

(First embodiment)
A first embodiment of the present invention will be 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 upper part of the wall panel. Further, when the mounting structure of this 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, and lower portions. It will be provided.

  FIG. 1 is a cross-sectional view illustrating the wall panel mounting structure of the present embodiment. 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 frames 2, such as a slab concrete floor.

  The wall panel 1 is provided with an O-bolt set 3 (an O-bolt 3a and a nut 3b) from the anchor steel rod A embedded in the wall panel 1 toward the outdoor side surface. As a result, the nut plate 3 is fixed to the wall panel 1 by screwing the nut 3b into the O bolt 3a in a state where the O bolt 3a is passed through the inertia plate 4. In addition, what is arrange | positioned in the wall panel 1 is not necessarily restricted to O bolt set 3, O nut set (O nut and bolt) may be sufficient.

  Further, the support member 5 is fixed by being in contact with the small edge surface 1 a and the side surface 1 b of the wall panel 1 and being sandwiched between the side surface 1 b and the inertia plate 4. As the support member 5, an angle steel with an L-shaped cross section having a horizontal plane and a vertical plane is used.

  The housing 2 and the support member 5 are connected by a concrete anchor (bar-shaped member) 6 having one end embedded in the housing 2 and the other end formed with a screw portion 6a. A plurality of nuts are screwed into the threaded portion 6 a of the concrete anchor 6 in the support member 5 fixed to the housing 2. More specifically, the concrete anchor 6 includes a nut 7 for fixing to the housing, a lower nut (positioning member) 8 for supporting the lower portion of the support member 5, and an upper nut disposed on the upper portion of the support member 5. (Three spacer members) 9 nuts are screwed together.

  The support member 5 and the concrete anchor 6 are fixed by sandwiching the upper and lower sides of the support member 5 with the upper nut 9 and the lower nut 8 in a state where the screw portion 6a is passed through the hole of the support member 5.

  Further, a mortar 10 is packed between the housing 2 and the support member 5, and a sealing 11 is packed between the wall panel 1 and the mortar 10.

  Next, a method for attaching the wall panel 1 will be described.

  First, the concrete anchor 6 is embedded in the housing 2. Then, the screw part 6a of the concrete anchor 6 protrudes from the housing 2 to the upper part.

  The nut 7 and the lower nut 8 are screwed into the threaded portion 6a of the concrete anchor 6 in this state. Thereafter, the hole of the support member 5 is passed through the screw portion 6 a and the support member 5 is brought into contact with the lower nut 8. Here, the position of the lower part of the support member 5 is adjusted by appropriately rotating the lower nut 8 along the screw part 6a and determining the position of the lower nut 8 with respect to the screw part 6a.

  After adjusting the position, the upper nut 9 is screwed into the threaded portion 6 a of the concrete anchor 6 protruding upward from the hole of the support member 5. Thereby, the upper nut 9 comes to a position opposite to the lower nut 8 with the support member 5 interposed therebetween.

  Next, the wall panel 1 and the support member 5 are fixed. Specifically, the wall panel 1 is placed on the horizontal surface of the support member 5 (via the upper nut 9). On the other hand, the side surface sandwiches a rising portion which is a vertical surface of the support member 5 between the wall panel 1 and the inertia plate 4. Thereafter, the nut 3b of the O bolt set 3 is fixed to the O bolt 3a. Thus, the wall panel 1 and the support member 5 are fixed.

  Thereafter, the mortar 10 and the sealing 11 are appropriately packed. Thereby, waterproofness and heat insulation are ensured.

  As described above, in the present embodiment, when the height from the housing 2 to the support member 5 is adjusted, the lower nut 8 screwed into the screw portion 6a of the concrete anchor 6 is rotated. Thus, since the position adjustment of the housing 2 and the support member 5 can be performed without performing the welding operation, the operation of attaching the wall panel 1 can be easily performed.

  Further, the position adjustment of the support member 5 can be performed by rotating the lower nut 8 that supports the lower portion of the support member 5, and it is not necessary to perform a welding operation, so that the fine position adjustment is facilitated. If the fixed position is not the desired position, the position can be easily corrected because the position can be finely adjusted by simply rotating the lower nut 8. In addition, for example, the outer wall of an RC apartment often has a slope, and the upper surface of the slab is difficult to obtain surface accuracy when placing concrete. According to the above wall panel mounting structure, the surface of the housing 2 is inclined. Even when there is a mark or when the surface accuracy of the surface of the housing 2 is low, it is easy to set the positions of the housing 2 and the support member 5 to a desired height. For this reason, a wall panel and a housing can be attached efficiently and work efficiency can be raised.

  Further, since there is no welding work, no skilled worker is required, and since anyone can easily adjust the position of the support member 5, work efficiency can be further increased.

  Further, in the present embodiment, an upper nut 9 is disposed on the support member 5. Here, if the concrete anchor 6 is installed in the center part of the wall panel 1, the upper nut 9 will be arrange | positioned on the support member 5 of the center part of the wall panel 1. FIG. When the wall panel 1 is placed on the support member 5, a spacer is required on the support member 5. According to the present embodiment, the upper nut 9 serves as a spacer. Further, since the upper nut 9 is screwed into the screw portion 6a, it does not shift. For this reason, it is possible to further increase the efficiency of the operation of attaching the wall panel 1 to the support member 5.

  Further, unlike the prior art, the wall panel 1 can be supported by only one support member without requiring a plurality of support members. Generally, the support member is made of metal, but the number of thermal bridges that transmit heat can be reduced by reducing the number of metal members. For this reason, heat insulation can be improved.

  Moreover, since the support member 5 can be stopped only with a bolt, the support member 5 can be easily removed. Further, since the rising portion extending in the vertical direction of the support member 5 is not fixed by welding, the support member 5 can be easily removed. The support member 5 can be easily recycled. Further, the support member 5 can be removed without destroying other components, and a new wall panel 1 mounting structure can be constructed on the concrete anchor 6. At this time, a concrete anchor 6 can be added as necessary.

(Second Embodiment)
Subsequently, a second embodiment of the present invention will be described. In this embodiment, the mounting structure of the finally completed wall panel 1 is the same as the mounting structure (FIG. 1) of the first embodiment, but the mounting method of the wall panel 1 is different from that of the first embodiment. Yes.

  In the present embodiment, the upper nut 9 functions as a spacer member interposed between the support member 5 and the small edge surface 1 a of the wall panel 1, and at a desired position before the support member 5 and the lower nut 8. It has the function to position the wall panel 1 and the support member 5 by adjusting to. Since the upper surface of the upper nut 9 contacts the small edge surface 1a of the wall panel 1, the upper surface of the upper nut 9 is hereinafter referred to as a panel contact surface 9a. Further, the lower nut 8 functions as a fastening member that is moved up and down after the positioning of the upper nut 9 to clamp and fix the support member 5 between the upper nut 9 and the lower nut 8.

  Hereinafter, the attachment method of the wall panel 1 in this embodiment is demonstrated.

  As shown in FIG. 1, first, a concrete anchor 6 is embedded in the housing 2. Then, the screw part 6a of the concrete anchor 6 protrudes from the housing 2 to the upper part.

  The nut 7 and the lower nut 8 are screwed into the threaded portion 6a of the concrete anchor 6 in this state. Thereafter, the hole of the support member 5 is disposed above the lower nut 8 so as to penetrate the screw portion 6a, and the upper nut 9 is screwed into the screw portion 6a protruding upward from the hole of the support member 5. Thereby, the upper nut 9 comes to a position opposite to the lower nut 8 with the support member 5 interposed therebetween.

  Thereafter, the upper nut 9 is appropriately rotated along the screw portion 6a to move the upper nut 9 up and down, thereby positioning the panel contact surface 9a in the vertical direction. Here, for example, the level of the panel contact surface 9a is accurately adjusted to a predetermined level with reference to the position of a reference black (not shown) displayed in advance on the housing 2.

  After adjusting the position of the upper nut 9, the lower nut 8 is rotated along the screw portion 6 a to move the lower nut 8 upward, and the support member 5 is sandwiched vertically between the upper nut 9 and the lower nut 8. Fasten and fix with. During the fastening and fixing, the aligned upper nut 9 is not rotated.

  Next, the wall panel 1 and the support member 5 are fixed. Specifically, the wall panel 1 is placed on the horizontal surface of the support member 5 (via the upper nut 9). That is, here, the small edge surface 1a of the wall panel 1 is abutted against the panel abutting surface 9a accurately aligned as described above, so that the small edge surface 1a is accurately positioned in the vertical direction, and as a result, the wall panel 1 Are accurately positioned in the vertical direction. On the other hand, a rising portion which is a vertical surface of the support member 5 is sandwiched between the side surface of the wall panel 1 and the inertia plate 4. Thereafter, the nut 3b of the O bolt set 3 is fixed to the O bolt 3a. Thus, the wall panel 1 and the support member 5 are fixed.

  Thereafter, the mortar 10 and the sealing 11 are appropriately packed. Thereby, waterproofness and heat insulation are ensured.

  In the mounting method of the second embodiment described above, the position of the panel contact surface 9a is first adjusted by moving the upper nut 9 up and down. Thereafter, in the step of fixing the support member 5, it is possible to fix the support member 5 by moving the lower nut 8 without moving the upper nut 9. According to such a method, since the height of the panel contact surface 9a on which the wall panel 1 is directly placed is directly adjusted, the level accuracy of the wall panel 1 can be improved.

  Moreover, since the support member 5 can be fixed using the upper nut 9 positioned first as a guide, the support member 5 can be easily positioned, and the above-described highly accurate positioning of the wall panel 1 can be performed efficiently. it can. As a result, the wall panel 1 can be efficiently attached.

  If the support member 5 is first positioned and the upper nut 9 is tightened according to the position of the support member 5, for example, if dust is caught under the upper nut 9, the panel contact surface 9 a There is a problem that the accuracy of the level of the final wall panel 1 is deteriorated because the level is incorrect. On the other hand, in the mounting method of the second embodiment, since the position of the panel contact surface 9a is first positioned, even if dust is caught under the upper nut 9, the final level of the wall panel 1 is reached. The problem of degrading the accuracy does not occur.

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