Description

  The present invention provides a lower PC plate non-bearing wall and an upper PC plate non-bearing wall with a part of a frame made up of pillars, floors, beams, etc. in a building such as a high-rise apartment building. The present invention relates to a non-bearing wall connecting structure and a connecting construction method in which a plurality of non-bearing walls are sequentially connected in the height direction.

  In high-rise buildings such as high-rise apartments, even non-bearing walls (walls that are not subject to stress load due to structural calculations) such as PC-paneled decorative walls, etc. For example, when a strong horizontal force is applied to the frame due to an earthquake or the like, the external force is transmitted to the non-bearing wall that is tightly connected to the frame, and the impact is applied to the non-bearing wall. In some cases, such as when a major earthquake occurs, there is a risk that the bearing wall will be destroyed and collapsed.

Therefore, there is a conventional structure in which the non-bearing wall is connected to the frame so that the external force applied to the frame during an earthquake is not directly transmitted to the non-bearing wall. For example, as shown in FIG. 9 (A), a height is obtained by connecting up and down decorative walls 2 and 3 made of non-bearing walls made of PC board with a rise 1a of a balcony 1 which is a part of a frame as being sandwiched therebetween. When the decorative pillar is constructed in the direction, the lower end of the decorative wall 2 on the upper floor and the balcony 1 are grouting the L-shaped anchor 5 embedded in the rise 1 a on the joint sleeve 4 embedded in the lower end of the decorative wall 2. On the other hand, the downstairs decorative wall 3 and the balcony 1 are connected to the ceiling corners of the decorative wall 3 and the rising edge 1a by fastening the angle plate 7 with anchor bolts 6a and 6b. As shown in B), the lower curved plate piece 7a of the angle plate 7 is provided with a long hole 8, and the angle plate 7 is fastened to the decorative wall 3 through the anchor bolt 6b in the long hole 8. Water along the long hole 8 with respect to the balcony 1 at the upper end And a structure coupled to the movable direction

  However, in the conventional non-bearing wall connecting structure described above, the angle plate 7 is fastened with the anchor bolts 6a and 6b from the outside, and the downstairs decorative wall 3 is connected to the balcony 1, so that the embedded portions of the anchor bolts 6a and 6b Rusts, which may lead to a decrease in connection strength. In addition, there is a problem that the construction at the site is not easy and the workability is poor because the construction involves a dangerous high place work such as fastening the angle plate 7 while standing on a stepladder. It was. Furthermore, since the anchor bolts 6a and 6b and the angle plate 7 are not exposed to the outside, it does not look good. After the angle plate 7 is fastened with the anchor bolts 6a and 6b, a decorative plate is attached and the anchor bolts 6a and 6b are attached. As shown in FIG. 9A, it is necessary to perform post-processing to cover and cover the concrete 9 as shown in FIG. 9A. In this respect, there is a problem that workability is poor.

Open the mouth 19 and fit the box The mouth 19 is exposed from the other end surface of the non-bearing wall 15, 20 ..., and the inlet 29 and the outlet 39 are exposed from the side wall surface on one side, and the other end portions 15b, 20b of the non-bearing wall 15, 20 ... ..., a sheath outer 35 embedded in, an adjustment nut 45 screwed into the male screw portion 25c, and a positioning base 40 having a shaft hole 50 through which the male screw portion 25c is inserted. The connecting shaft portion 25b is embedded and fixed in the housing frame A with the male thread portion 25c of the anchor rebar 25 protruding from the upper surface or the lower surface of the housing, and the adjusting nut 45 is screwed to the housing frame A. After the male screw portion 25c is passed through the shaft hole 50 to hold the positioning receiving base 40, the male inner screw portion 25c is covered with the sheath inner 30 and arranged in the in-plane direction X of the wall surface W. On the other hand, when the other non-bearing wall 20 is suspended and the sheath outer 35 is put on the sheath inner 30 from the box insertion opening 19, the grout is placed between the sheaths 30 and 35 and the positioning cradle 40. A hollow frame-shaped cylindrical portion 60a is formed, and the movement in the out-of-plane direction Y perpendicular to the in-plane direction X of the wall surface W is sandwiched in the sheath inner 30 with the male screw portion 25c interposed therebetween. In the in-plane direction X, a joint sleeve 60 is formed in which a guide space 60b that is movably accommodated is formed, and the joint sleeve 60 is slidably connected to the housing frame A via the joint sleeve 60. It is characterized by.

  The invention according to claim 2 is, for example, as shown in the embodiment shown below, with either one of the upper and lower PC plate non-bearing walls 15 and the other non-PC plate non-bearing wall sandwiching a part of the frame A. In the non-bearing wall connecting construction method in which the load-bearing walls 20 are connected by the joint means J and a plurality of non-bearing walls are successively arranged in the height direction of the building, the joint means J is screwed with a male screw portion 25c at the tip.

When connected, the male screw portion of the anchor rebar 25 The connecting shaft portion 25b is embedded in the housing frame A in a state where 25c protrudes from the upper surface or the lower surface of the housing, and the one non-bearing wall 15 is fixed. Then, the adjustment nut 45 is attached to the male screw of the anchor reinforcing bar 25. After screwing into the portion 25c, the male screw portion 25c is passed through the shaft hole 55 to hold the positioning cradle 40, and then the sheath inner 30 is attached to the male screw portion 25c. Then, the other outer non-bearing wall 20 is hung and the sheath outer 35 is covered from the box fitting opening 19 onto the sheath inner 30 to cover both sheaths 30. 35 and a hollow frame-shaped cylindrical portion 60a filled with grout is formed between the positioning receiving base 40 and a surface perpendicular to the in-plane direction X of the wall surface W with the male screw portion 25c interposed in the sheath inner 30. A joint sleeve 60 in which a guide space 60b that is movably accommodated is formed in the in-plane direction X while the movement in the outer direction Y is restricted, is slid with respect to the positioning cradle 40 via the joint sleeve 60. The other non-bearing wall 20 is connected to the housing frame A as possible, and then the adjustment nut 45 is screwed to finely adjust the connection height position of the other non-bearing wall 20 via the positioning cradle 40. The joint sleeve 60 is filled with grout after adjusting and aligning the joint position with the housing frame A.

  According to the present invention, the anchor reinforcing bar of the joint means is embedded in one PC plate non-bearing wall and the frame, and other joint means such as a sheath inner is also provided between the other PC plate non-bearing wall and the frame. Since the non-bearing wall made of PC plates is connected to the frame in the embedded state, there is no room for rusting in the joint means, and therefore the external force applied to the frame during an earthquake is not reduced due to rusting and the connection strength does not decrease. The non-bearing wall can be connected to the frame so that it is not transmitted to the non-bearing wall as it is. In addition, there is no need to apply extra post-processing such as covering the exposed joint means with a decorative board or concrete for the sake of appearance and fire prevention measures, so construction efficiency is good and non-bearing walls can be easily connected to the frame. Can do. Moreover, when a non-bearing wall made of PC plate is suspended and the sheath outer embedded at the other end is covered with the sheath inner, a hollow frame-shaped cylindrical portion for filling grout is formed between the sheath and the positioning cradle, In the sheath inner, a joint sleeve is formed in which a guide space is formed in which the male thread portion of the anchor rebar is movably accommodated in the in-plane direction of the wall surface. As it is assembled, the construction efficiency increases, and the non-bearing wall can be easily connected to the frame.

  In addition, according to the present invention, even when the non-bearing wall made of PC plate is connected to the frame and a plurality of non-bearing walls are sequentially arranged in the height direction of the building, By simply turning the screw, the PC board non-bearing wall can be moved up and down to finely adjust the connection height position. This makes it possible to shift the joint position between the PC board non-bearing wall and the frame. It is possible to easily perform alignment that is aligned with a line so as not to occur.

  Furthermore, according to the present invention, after finely adjusting the connection height position of the PC plate non-bearing wall, the joint sleeve is filled with grout, and when the grout is hardened, the joint sleeve surrounds the sheath inner with the hardened grout. The guide is fixed in a fixed position with the male screw part of the anchor rebar and the movement of the male screw part is movably accommodated in the left and right direction in the in-plane direction while restricting the movement in the out-of-plane direction perpendicular to the in-plane direction of the wall surface Hold the space inside the sheath inner. As a result, (1) when connecting the non-bearing wall made of PC plate to the chassis frame, it can be connected to the chassis frame at a fixed connection position without shifting in the out-of-plane direction Y at the other end. On the other hand, (2) Even if an earthquake occurs and a strong horizontal force is applied to the chassis frame and the chassis frame swings, the non-bearing wall made of PC plate is guided in the guide space with the other end held firmly by the joint sleeve. Because it is slidable in the left and right direction, it moves following the shaking of the frame and cushions the external force applied to the frame, so that the external force is not transmitted from the frame to the non-bearing wall made of PC board. It is possible to reliably prevent the non-bearing wall made of PC plate from being damaged.
