Description

  The present invention relates to a wall panel structure installed as a wall of a building, and a panel member provided in a plurality in a wall width direction of the building.

  2. Description of the Related Art Conventionally, in a frame wall construction method such as a two-by-four structure, a wooden wall panel structure, or a thin lightweight steel structure, a wall panel disclosed in Non-Patent Document 1 is used as a resistance element against a horizontal force acting due to an earthquake, wind, or the like. Widely used.

  Here, as shown in FIG. 10, the wall panel 9 disclosed in Non-Patent Document 1 includes a face material 91 that resists horizontal shear force, a frame material 92 that restrains four sides of the face material 91, and a frame material 92. And a horizontal crossbar 93 for stiffening. The wall panel 9 disclosed in Non-Patent Document 1 is characterized in that when a horizontal force acts, the face material 91 is sheared and resists the horizontal force, and the shear force acting on the face material 91 is bonded to the frame material 92. The axial force is transmitted to the frame member 92 via the location.

  Further, in the wall panel 9 disclosed in Non-Patent Document 1, when the shear deformation of the face material 91 becomes large, a tensile force in an oblique direction is generated as oblique tension P, and the vertical frame 92 a constituting the frame material 92 is 91 is pulled in the in-plane direction. For this reason, the wall panel 9 disclosed in Non-Patent Document 1 has a horizontal bar 93 laid between a pair of vertical frames 92a to suppress the vertical frame 92a from being bent due to the oblique tension P, and to be stable. It is necessary to exhibit high resistance performance.

  As a result, the wall panel 9 disclosed in Non-Patent Document 1 applies a compressive force C in a direction of bending the vertical frame 92a to the horizontal rail 93 provided on the pair of vertical frames 92a. The warpage of the wall 92a is suppressed, and stable resistance performance can be secured as a whole of the wall panel 9.

  In the current framed wall construction, for example, the wall of the building is configured by a wall panel structure in which a plurality of wall panels 9 to which a face material 91 having a width of 455 mm is attached are continuously arranged. In this wall panel structure, as shown in FIG. 10 (a), each wall panel 9 is integrated with the adjacent wall panel 9, so that the plurality of wall panels 9 behave integrally. Resist horizontal forces such as earthquakes and wind.

  In this wall panel structure, as shown in FIG. 10A, when the vertical frames 92a of each wall panel 9 are integrated, when the shear deformation of the face material 91 of each wall panel 9 increases. Thus, the oblique tension P is transmitted in the diagonal direction of the wall panel structure, so that the entire corner 9a of the integrated wall panel 9 does not bear the load. For this reason, the maximum horizontal proof stress that the wall panel structure can bear is lower than the sum of the member proof strengths of the respective wall panels 9, and there is a risk that the designer may unexpectedly decrease the early proof stress and the deformation performance. is there. Therefore, in this wall panel structure, as shown in FIG. 10 (b), edges of the adjacent wall panels 9 are cut to prevent the members of the wall panels 9 from being reduced in proof stress and deformation performance at an early stage. Each wall panel 9 is designed to independently resist horizontal force.

  In this way, by cutting the adjacent wall panels 9 from each other, each horizontal rail 93 bears only the compressive force C and does not bear the oblique tension P, and straddles a plurality of wall panels 9. The generation of the oblique tension P is suppressed. For this reason, in the conventional wall panel structure, as shown in FIG. 11, the horizontal rail 93 is attached using a drill screw 94 protruding from the outer side B to the inner side A of the vertical frame 92a, and the wall panels adjacent to each other are mounted. 9 are cut off.

  However, in the conventional wall panel structure, since the vertical frames 92a are arranged adjacent to each other on the outer side B after the plurality of wall panels 9 are installed, the vertical frames 92a are installed after the wall panels 9 are installed. Cannot be joined by the drill screw 94 from the outer side B. For this reason, in the conventional wall panel structure, at the stage of assembling each wall panel 9, it is necessary to install a plurality of wall panels 9 after joining the horizontal rail 93 to the vertical frame 92 a.

  At this time, in the conventional wall panel structure, as shown in FIG. 11A, a plurality of wall panels 9 are installed adjacent to each other. When the irregularity occurs in the wall panel 9, when the plurality of wall panels 9 are installed next to each other, the wall panels 9 interfere with each other, and the installation becomes difficult. For this reason, in the manufacturing process of the wall panel 9, it is necessary to perform strict accuracy control so that the width dimensions of the three members of the horizontal frame 92 b, the horizontal rail 93, and the face material 91 match each other. This has led to increased costs. Further, in the conventional wall panel structure, as shown in FIG. 11B, when a plurality of wall panels 9 are installed next to each other, the heads 94a of the drill screws 94 protrude from the outer side B of the vertical frame 92a to mutually protrude. The interference lowers the construction accuracy and construction efficiency when installing the wall panel 9.

  Therefore, the present invention has been devised in view of the above-described problems, and an object of the present invention is to improve the manufacturability of a panel member and to improve the work accuracy when installing a plurality of panel members. It is to provide a wall panel structure and a panel member which improved.

While being joined, the shaft portion of the screw member is continuously joined to the cutout portion formed in the flat plate portion of the vertical frame and the horizontal rail in the panel member adjacent in the wall width direction without being joined. It is characterized by being provided.

  A wall panel structure according to a second invention is characterized in that, in the first invention, the crosspiece is formed as an opening having an outer diameter larger than that of the shaft of the screw member.

  In the wall panel structure according to a third aspect of the present invention, in the first aspect, the notch portion in which the flat plate portion is partially cut out is formed as the cut portion so that the cross rail does not interfere with the shaft portion of the screw member. It is characterized by being formed.

A panel member according to a fourth aspect of the present invention is a panel member that is provided in a plural number in the width direction of a building, and includes a pair of vertical frames and a horizontal frame separated from each other, and a pair of the vertical frames.

Thus, it is possible to secure stable resistance performance in the entire wall panel structure.

According to the first to fourth inventions, since a plurality of panel members adjacent to each other in the wall width direction are cut off, generation of oblique tension across the plurality of panel members is suppressed, and the entire surface of the wall panel structure is formed. By realizing the load distribution over the range, it is possible to suppress the early decrease in the proof stress and the early decrease in the deformation performance of the members constituting the wall panel structure.

The flat plate portion 40 of the horizontal rail 4 is joined to the vertical frame 31.

  Here, in the wall panel structure 1 to which the present invention is applied, as shown in FIG. 7, when the shear deformation of the face material 5 increases, an oblique tensile force is generated as oblique tension P in the entire wall panel structure 1. Then, the vertical frame 31 is deformed so as to be bent by being pulled in the in-plane direction of the face material 5.

  At this time, in the wall panel structure 1 to which the present invention is applied, the horizontal rail 4 bears the compressive force C in the direction of bending the vertical frame 31 by the horizontal rail 4 being laid on the pair of vertical frames 31. As a result, the wall panel structure 1 to which the present invention is applied has a structure in which the horizontal rail 4 bears the compressive force C in the direction of bending the vertical frame 31 and suppresses the bending of the vertical frame 31. It is possible to secure stable resistance performance as a whole.

  In addition, the wall panel structure 1 to which the present invention is applied is generally provided with an opening having a large outer diameter in order to absorb a construction error, whereas, as shown in FIG. In order to cut off the screw member 8 from the vertical frame 31 and the horizontal rail 4 in the other panel member 2 adjacent to the X, a defective portion 7 such as an opening 70 is provided.

  For this reason, as shown in FIG. 8A, the wall panel structure 1 to which the present invention is applied includes the vertical frame 31 and the horizontal rail 4 in the other panel member 2 adjacent in the wall width direction X and the wall width direction. The vertical frame 31 and the horizontal rail 4 in one panel member 2 adjacent to X are in a state of being cut off from each other. As shown in FIG. 8B, the wall panel structure 1 to which the present invention is applied has a plurality of panel members 2 adjacent to each other in the wall width direction X without being integrated by the screw members 8. When the horizontal rails 4 are cut off from each other, the vertical frames 31 deform so as to be separated from each other in the wall width direction X and bend.

  At this time, as shown in FIG. 7, the wall panel structure 1 to which the present invention is applied has a plurality of panel members 2 that are adjacent to each other in the wall width direction X and are cut off. The generation of the oblique tension P straddling is suppressed. As a result, the wall panel structure 1 to which the present invention is applied suppresses the generation of the oblique tension P straddling the plurality of panel members 2 and achieves load distribution over the entire surface of the wall panel structure 1. It is possible to suppress early deterioration in proof stress and deterioration in deformation performance of the members constituting the panel structure 1.

  Further, in the wall panel structure 1 to which the present invention is applied, the plurality of panel members 2 adjacent in the wall width direction X are cut off from each other, and the generation of the oblique tension P across the plurality of panel members 2 is suppressed. Thus, only the compressive force C is applied to each cross rail 4 and the oblique tension P is not applied. Thereby, in the wall panel structure 1 to which the present invention is applied, since each of the cross rails 4 does not bear the oblique tension P, a decrease in early proof stress and a deterioration in deformation performance due to buckling of the cross rail 4 is suppressed. It becomes possible.

  Here, in the conventional wall panel structure, as shown in FIG. 11A, since a plurality of wall panels 9 are installed adjacent to each other, for example, a vertical frame 92 a may appear during the manufacturing process of the wall panels 9. When the irregularity occurs in the wall panel 9, when the plurality of wall panels 9 are installed next to each other, the wall panels 9 interfere with each other, and the installation becomes difficult. For this reason, in the manufacturing process of the wall panel 9, it is necessary to perform strict accuracy control so that the width dimensions of the three members of the horizontal frame 92 b, the horizontal rail 93, and the face material 91 match each other. This has led to increased costs. Further, in the conventional wall panel structure, as shown in FIG. 11B, the head 94a of the drill screw 94 projects from the vertical frame 92a and interferes with each other. Efficiency decreases.

  On the other hand, in the wall panel structure 1 to which the present invention is applied, as shown in FIG. 8, the screw member 8 inserted into the screw hole 41 is vertically inserted from the inside A of the vertical frame 31 on which the horizontal rail 4 is installed. It is joined to the side plate 31a of the frame 31. Therefore, in the wall panel structure 1 to which the present invention is applied, as shown in FIG. 9A, it is necessary to connect the horizontal rail 4 to the vertical frame 31 at a stage before the plurality of panel members 2 are installed. It will not be. Then, as shown in FIG. 9B, the wall panel structure 1 to which the present invention is applied has the length L of the horizontal rail 4 adjusted to the accuracy of the panel width in a state after the plurality of panel members 2 are installed. Can be finely adjusted, and the horizontal rail 4 can be easily connected to the vertical frame 31 with high accuracy.

  Thereby, in the wall panel structure 1 to which the present invention is applied, after the plurality of panel members 2 are installed, the screw members 8 can be joined from the inside A of the vertical frame 31 as shown in FIG. Thus, it is possible to improve the manufacturability of each panel member 2 and suppress an increase in the manufacturing cost of the panel member 2. Further, in the wall panel structure 1 to which the present invention is applied, the head 80 or the shaft portion 81 of the screw member 8 does not protrude to the outside B of the vertical frame 31 before the plurality of panel members 2 are installed. The head portion 80 or the shaft portion 81 of the member 8 does not interfere with each other, it is possible to improve the workability when installing the plurality of panel members 2, and it is possible to improve the construction accuracy and suppress the construction cost. .

  As shown in FIG. 4, the wall panel structure 1 to which the present invention is applied particularly combines the channel steel and the rectangular steel pipe in the vertical frames 31 arranged on both sides in the wall width direction X, thereby increasing the wall height. It is possible to sufficiently resist a load applied from above in the direction Z. At this time, the vertical frames 31 arranged on both sides in the wall width direction X have one or two channel steels and two square steel pipes as shown in FIGS. 12 (a) and 12 (b). 12 (c) to 12 (e), and a plurality of channel steels or the like may be combined with each other by back-to-back or the like.

  The wall panel structure 1 to which the present invention is applied has a resistance performance when a horizontal force acts due to an earthquake or the like. It can be seen that all of the proof stresses are equivalent to the conventional wall panel structure. From this, it was verified that the wall panel structure 1 to which the present invention was applied can secure the same resistance performance as the conventional wall panel structure while improving manufacturability, construction accuracy, and construction efficiency.

  As described above, the example of the embodiment of the present invention has been described in detail. However, each of the above-described embodiments is merely an example of the embodiment for carrying out the present invention. The scope should not be construed as limiting.
