Description

[Technical Field]

[0001] The present invention relates to a sliding support that connects the upper side of a panel to a building frame, and to a panel-installed building structure that uses this sliding support. [Background technology]

[0002] Patent Document 1 discloses a method for installing precast spandrel walls (PCa spandrel walls). In this method, a fitting groove is formed on the top surface of the foundation, located outside the columns, in the direction of column alignment. A fitting protrusion that fits into the fitting groove is formed at the lower end of the precast spandrel wall. A hook is protruded from the inside surface of the lower part of the precast spandrel wall. The precast spandrel wall is placed outside the columns, and the fitting protrusion is fitted into the fitting groove to erect it. The upper part of the precast spandrel wall is temporarily fixed to the columns with bolt fastening means. Next, a crowbar is hung on the hook of the precast spandrel wall, and the position of the precast spandrel wall is adjusted using this crowbar. After this adjustment, the bolt fastening means at the upper part of the precast spandrel wall is fully tightened to install the PCa spandrel wall to the columns.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-240243 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional precast spandrel wall structure, if an earthquake causes the columns to displace horizontally within the plane of the precast spandrel wall panels, the precast spandrel wall panels may be pulled by the column displacement, resulting in damage to the panels. Similarly, if the gaps (joints) between the precast spandrel wall panels are deformed, the water-stopping material placed in the gaps may be damaged.

[0005] In view of the above circumstances, an object of the present invention is to provide a sliding support and a panel-installed building structure that can prevent damage to panels and water-stopping materials in the joints between panels due to earthquakes. [Means for solving the problem]

[0006] The sliding support of the present invention is a sliding support that connects the upper side of a panel to a building skeleton, a connecting portion that fixes the panel to the building skeleton in the out-of-plane direction and the in-plane vertical direction of the panel, while suppressing the transmission of displacement of the building skeleton during inter-story deformation to the panel in the in-plane horizontal direction by sliding relative to the panel; and an ingress / egress adjustment member that protrudes into the gap between the sliding support and the indoor side of the panel and contacts the indoor side.

[0007] With the above configuration, the connecting portion prevents the transmission of displacement of the building skeleton during inter-story deformation to the panel in the horizontal direction within the plane by sliding relative to the panel, thereby preventing damage to the panel due to displacement of the building skeleton. Similarly, deformation of the gap between the panels is also prevented, preventing damage to the water-stopping material disposed in the gap. Furthermore, since the ingress / egress control member protrudes into the gap between the sliding support and the indoor side of the panel and contacts the indoor side, the ingress / egress control member can eliminate errors in the amount of ingress / egress of the panel. Furthermore, since the ingress / egress control member contacts the indoor side, smoothness of displacement (movement) of the building skeleton (connecting portion) during inter-story deformation relative to the panel is improved.

[0008] In the sliding support, the tip of the inward / outward movement adjusting member may have a spherical shape, which allows the inward / outward movement adjusting member to slide more smoothly relative to the panel during interlayer deformation.

[0009] The connecting portion comprises a body-side fixing device fixed to the building body, an insert fastening portion attached to the upper side of the indoor side of the panel, and a fastening member that fastens the body-side fixing device and the insert fastening portion, and the body-side fixing device has a loose hole through which the fastening member is inserted, and this loose hole is larger than the outer shape of the fastening member, so that displacement of the body-side fixing device in the horizontal direction within the plane is permitted.

[0010] In the sliding support, a slotted plate having a slot formed therein that allows displacement of the frame-side fixing device in the horizontal direction within the plane while restricting vertical movement within the plane may be placed on top of the frame-side fixing device and fixed to the frame-side fixing device by welding. This welding can be performed at the panel installation site, so that errors that occur in the panel-installed building structure can be easily eliminated on site.

[0011] The sliding support may include a sliding plate member that reduces friction between the head side of the fastening member and the body-side fixing device, thereby allowing the fastening member to slide appropriately relative to the panel.

[0012] In addition, the panel-installed building structure of this invention is a panel-installed building structure in which the sliding support is attached to the upper building structure and the upper side of the panel is supported by the sliding support, and is characterized in that the tip of the entrance / exit adjustment member comes into contact with the panel-side sliding plate portion provided on the indoor side of the panel.

[0013] In a panel-installed building structure of this configuration, the horizontal displacement of the building structure during inter-layer deformation in the panel's plane is prevented from being transmitted to the panel by sliding relative to the panel, thereby preventing the panel from being damaged by displacement of the building structure.

[0014] In the panel-installed building structure, the lower side of the panel may be fixed to the building skeleton in both the out-of-plane direction and the in-plane direction by a lower fixing part attached to the building skeleton below. In this way, the lower side of the panel is maintained fixed in both the out-of-plane direction and the in-plane direction by the lower fixing part even during inter-story deformation.

[0015] In the panel-installed building structure, the lower fixing portion may include an inward / outward movement adjusting member that protrudes into a gap between the lower fixing portion and the indoor side surface of the panel and contacts the indoor side surface. In this way, an error in the amount of inward / outward movement of the panel can be eliminated by the inward / outward movement adjusting member. [Effects of the Invention]

[0016] The present invention has the effect of suppressing damage to panels and damage to water-stopping materials in the joints between panels due to earthquakes. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. As shown in Figures 1 and 2, in the panel-installed building structure of this embodiment, multiple precast waist wall panels 1 are placed on the outdoor side of steel-framed columns (building skeleton) 7 on a concrete foundation (building skeleton) 6. The lower side of each precast waist wall panel 1 is connected to the foundation 6 by a lower fixing part 2, and the upper side of the precast waist wall panel 1 is connected to the column 7 by an upper fixing part 3, which is a sliding support.

[0019] In this embodiment, the foundation 6 comprises a foundation body and an upper recess 6a provided on the foundation body. The precast spandrel wall panel 1 is placed on the upper recess 6a, with the flat underside of the precast spandrel wall panel 1 positioned above the base plate 7a of the column 7. The base plate 7a is fixed onto a concrete column base 61 that is fabricated together with the foundation 6.

[0020] A water-stop material 8 is installed in the joint between two adjacent precast spandrel wall panels 1. A water-stop material 9 is also placed between the bottom of the precast spandrel wall panel 1 and the top of the foundation 6. These water-stop materials 8, 9 consist of sealants and gaskets incorporated into the precast spandrel wall panel 1, as well as polyethylene foam and other materials separately disposed from the precast spandrel wall panel 1. As shown in FIG. 2 , the precast spandrel wall panel 1 has a structure in which a gasket 1G is sandwiched between concrete plates. The lower side of the gasket 1G has a roughly T-shaped branch toward the indoor side, with the tip of this branch exposed on the concrete floor 50 side. This exposed portion prevents water from penetrating from the outdoors into the concrete floor 50 side. The gasket 1G is not limited to the above structure. For example, the gasket 1G may be attached to the indoor surface of the precast spandrel wall panel 1, with the lower side of the gasket 1G bent at an angle toward the outdoors. The bent portion prevents water from entering the concrete floor 50 side from the outside.

[0021] The lower fixing portion 2 fixes the precast waist wall panel 1 to the foundation 6 in both the out-of-plane direction and the in-plane direction of the precast waist wall panel 1. The lower fixing portion 2 includes, for example, a foundation-side fixing device 21 located at the top edge of the foundation and fixed to an anchor portion 20 buried in the upper part of the foundation 6, a lower insert fastening portion (insert nut or the like) 22 attached to the lower side of the indoor side of the precast waist wall panel 1, and a lower fastening member 23 such as a bolt with a washer that fastens the foundation-side fixing device 21 and the lower insert fastening portion 22 together.

[0022] The anchor portion 20 comprises an embedded portion 20a embedded in the upper recess portion 6a of the foundation 6 and a horizontal plate portion 20b welded to the top of the embedded portion 20a, and is plated to prevent rust. The upper surface of the horizontal plate portion 20b is exposed above the upper recess portion 6a. The anchor portion 20 is set before the upper recess portion 6a is made of concrete and is fixed in place when the concrete hardens.

[0023] The foundation-side fixing device 21 is, for example, an equilateral angle having two sides of equal length. As shown in Figure 3, one side of this equilateral angle, the lower plate portion 21a, is placed on the upper surface of the horizontal plate portion 20b, and the other side of the equilateral angle, the upright plate portion 21b, faces the indoor side of the precast spandrel panel 1. A vertically long slot 211 is formed in the center of the upright plate portion 21b.

[0024] A fixing plate 24 is disposed vertically on the indoor side of the rising plate portion 21b of the foundation-side fixing device 21. A circular through-hole large enough to receive the threaded portion of the lower fastening member 23 is formed in the center of the fixing plate 24. The threaded portion of the lower fastening member 23 is inserted through the circular through-hole and the elongated hole 211 and is screwed into the lower insert fastening portion 22 within the height range of the elongated hole 211, allowing for some error in the vertical fastening position of the lower fastening member 23. With this positional error allowed and the lower fastening member 23 screwed into the lower insert fastening portion 22, the fixing plate 24 is fixed to the rising plate portion 21b of the foundation-side fixing device 21 at welded portion W1. The lower plate portion 21a is fixed to the upper surface of the horizontal plate portion 20b of the anchor portion 20 at welded portion W2. This welding work is carried out in a state where the horizontal position of the foundation side fixture 21 has been determined by the screwing of the lower fastening member 23.

[0025] As shown in Figures 4(A) and 4(B), the upper fixing part (sliding support) 3 comprises a column side fixing device (body side fixing device) 31 fixed to the side of the column 7, an upper insert fastening part (insert nut, etc.) 32 attached to the upper side of the indoor side of the precast waist wall panel 1, an upper fastening member 33 such as a washer-equipped bolt that fastens the column side fixing device 31 and the upper insert fastening part 32, and an in / out adjustment member 30.

[0026] That is, the upper fixing part 3 which is a sliding support includes a column side fixing part (body side fixing part) 31, a connecting part 35 which is made up of an upper insert fastening part 32 and an upper fastening member 33, and an in / out adjusting member 30.

[0027] The upper side of the precast waist wall panel 1 is fixed to the column 7 by the upper fixing part 3 in the out-of-plane direction of the precast waist wall panel 1 and in the vertical direction within the plane. Meanwhile, the upper fixing part 3 prevents the transmission of displacement during inter-story deformation of the column 7 to the precast waist wall panel 1 in the horizontal direction within the plane by sliding relative to the precast waist wall panel 1.

[0028] The column-side fastener 31 is, for example, an equilateral angle with two sides of equal length. One side plate portion 31a of this equilateral angle is fixed to the side surface of the column 7 by welding in advance. The other side plate portion 31b of the equilateral angle faces the indoor side surface of the precast spandrel wall panel 1. As shown in Figure 5, a loose hole 311 is formed in the center of the other side plate portion 31b, in which the upper fastening member 33 is positioned. This loose hole 311 is larger than the outer shape of the upper fastening member 33, allowing for displacement of the column-side fastener 31 (column 7) in the horizontal direction within the surface of the precast spandrel wall panel 1 and also allowing for errors that may occur in the installation of the upper fastening member 33, etc. The length of the horizontal straight portion of the loose hole 311 is, for example, approximately 53 mm, and the length of the vertical straight portion is, for example, approximately 20 mm.

[0029] The access adjustment member 30 has an access adjustment function that adjusts the access of the precast waist wall panel 1. The access adjustment member 30 consists of a headed bolt that is screwed into the screw hole 312 of the other side plate portion 31b. The bolt tip portion 301 of the access adjustment member 30 protrudes into the gap between the outdoor side surface of the other side plate portion 31b of the column-side fixing device 31 and the indoor side surface of the precast waist wall panel 1.

[0030] Bolt tip 301 is ground into a spherical shape to prevent contact bias or wedging action. Meanwhile, a metal sliding plate (panel-side sliding plate) 11 that comes into contact with bolt tip 301 to cause sliding is attached to the indoor side of precast spandrel panel 1. The indoor side of precast spandrel panel 1 is made of concrete, and sliding plate 11 is embedded in the concrete, exposing the contact surface with bolt tip 301. Note that upper insert fastening portion 32 may be provided within the arrangement area of ​​sliding plate 11, penetrating said sliding plate 11.

[0031] The upper fixing part 3 also has a slotted plate 36 superimposed on the indoor side of the column-side fixing device 31. The slotted plate 36 has slots 361 through which the upper fastening members 33 are passed. The slots 361 are elongated in the horizontal direction, allowing the column-side fixing device 31 to move horizontally within the plane of the precast waist wall panel 1 relative to the upper fastening members 33, while restricting the precast waist wall panel 1 from moving vertically within the plane relative to the upper fastening members 33. The length of the straight edge portion of the slots 361 is, for example, about 32 mm.

[0032] A stainless steel plate 37 is provided on the indoor side of the slotted plate 36, in contact with the indoor side. Circular through-holes 37a are formed in this stainless steel plate 37, through which the screw portions of the upper fastening members 33 are passed. The stainless steel plate 37 is a sliding plate material that reduces friction between a pressing plate 38 on the head side of the upper fastening members 33 and the slotted plate 36 on the other side plate portion 31b side.

[0033] The presser plate 38 is provided between the stainless steel plate 37 and the head of the upper fastening member 33. The presser plate 38 is formed with a circular through-hole 38a through which the screw portion of the upper fastening member 33 passes.

[0034] The slotted plate 36 is fixed to the other side plate portion 31b at a welding point W3. This welding operation is performed with the upper fastening member 33 in a screwed state.

[0035] With the above configuration, connecting part 35 prevents displacement of column 7 during inter-layer deformation from being transmitted to precast waist wall panel 1 in the horizontal direction within the plane of precast waist wall panel 1 by sliding relative to said precast waist wall panel 1, thereby preventing damage to precast waist wall panel 1 due to displacement of column 7. Similarly, deformation of the gaps between precast waist wall panels 1 is also prevented, thereby preventing damage to water-stopping material 8 placed in said gaps. Furthermore, because entry / exit adjustment member 30 protrudes into the gap between upper fixing part 3 and the indoor side surface of precast waist wall panel 1 and comes into contact with the indoor side surface, entry / exit adjustment member 30 can eliminate any error in the amount of entry / exit of precast waist wall panel 1.

[0036] Here, if a gap plate is placed in the gap between the upper fixing part 3 and the indoor side of the precast waist wall panel 1 instead of the access adjustment member 30 to fill this gap, slippage occurs at the point of contact between this gap plate and the other side plate part 31b during interlayer deformation. In contrast, with the upper fixing part 3 equipped with the access adjustment member 30, slippage occurs at the point between the bolt tip part 301 of the access adjustment member 30 and the sliding plate part 11 during interlayer deformation. The smoothness of displacement (movement) of the column 7 (column-side fixing device 31) relative to the precast waist wall panel 1 during interlayer deformation was better with the upper fixing part 3 equipped with the access adjustment member 30 than with the structure using the above-mentioned gap plate.

[0037] The tightening torque of the upper fastening member 33 is related to the contact pressure of the bolt tip 301 against the sliding plate 11, and since the displacement of the column 7 during interlayer deformation affects the force (friction force) transmitted to the precast spandrel panel 1, several interlayer deformation follow-up tests (interlayer deformation angles R = 1 / 120 rad, R = 1 / 60 rad, etc.) were conducted in fastening states with different tightening torques to determine the appropriate torque. In these tests, even with a tightening torque greater than the level at which the spring washer of the fastening member 33 was crushed, slippage relative to the precast spandrel panel 1 was generated, preventing damage to the precast spandrel panel 1. The fastening member 33 used in these tests had a spherical bolt tip 301.

[0038] In this embodiment, the foundation-side fixing device 21 is fixed by welding to the top of the anchor part 20. This welding can be performed at the installation site of the precast spandrel wall panel 1, so errors that occur in the precast spandrel wall installation structure can be easily eliminated on site.

[0039] In this embodiment, the slotted plate 36 is placed on the column-side fastener 31 and fixed to the column-side fastener 31 by welding. This welding can be performed at the installation site of the precast spandrel wall panel 1, so errors that occur in the precast spandrel wall installation structure can be easily eliminated on site.

[0040] Next, we will briefly explain the construction process for a precast spandrel wall installation structure. Formwork is created on the construction site, and concrete is poured to create the foundation 6 and column bases 61 for installing the columns. In this construction example, the top end of the foundation body side of the foundation 6 is lower than the top end of the column bases 61, but the precast spandrel wall panel 1 is placed on the upper recess 6a that forms the top of the foundation 6, so that the flat underside of the precast spandrel wall panel 1 can be positioned above the base plate 71 of the column 7. This eliminates the need to create a step on the underside of the precast spandrel wall panel 1, improving construction efficiency.

[0041] After the foundation 6 and other components are prepared and cured, scaffolding is erected around the foundation 6, and columns 7 are erected using a lifting machine placed indoors. A separate water-stop material, which will form part of the water-stop material 9, is also installed on the foundation 6. Using the lifting machine, the precast spandrel wall panel 1 is placed on the foundation 6, and the precast spandrel wall panel 1 is temporarily fixed to the columns 7 with fastening members 33 using column-side fasteners 31. Water-stop material 8 is placed at the edge of the precast spandrel wall panel 1. The horizontal position of the precast spandrel wall panel 1 is adjusted using access adjustment members 30, and the level of the precast spandrel wall panel 1 is also adjusted. Fastening members 33 are finally tightened. Lower fixing members 2 are attached to the lower side of the precast spandrel wall panel 1. On-site welding is performed on the column-side fasteners 31 and lower fixing members 2. This on-site weld is then touched up with anti-rust paint or plating repair paint. A buffer member 51 is placed on the surface of the precast spandrel wall panel 1 that contacts the concrete floor 50 to disconnect them. Concrete is poured using the precast waist wall panel 1 as a formwork to produce the concrete 50 on the earthen floor side.

[0042] Next, another embodiment will be described with reference to Fig. 6. The panel-installed building structure of this embodiment has a concrete exterior wall panel 101 installed outdoors between a lower steel beam 601, which is the building skeleton, and an upper steel beam 602, which is also the building skeleton. The lower side of the exterior wall panel 101 is connected to the lower steel beam 601 by a lower fixing part 2A.

[0043] The lower fixing portion 2A includes a beam-mounted fixing device 21A fixed to a base portion 601a welded to a lower steel beam 601, a lower insert fastening portion (such as an insert nut) 22 attached to the lower side of the indoor side of the exterior wall panel 101, and a lower fastening member 23 such as a washer-equipped bolt that fastens the foundation-mounted fixing device 21 and the lower insert fastening portion 22. The beam-mounted fixing device 21A is, for example, an equilateral angle having two sides of equal length. One side of this equilateral angle, the lower plate portion, is fixed to the lower steel beam 601 by a fastening mechanism 26 with a height-adjustable bolt. Meanwhile, the other side of the equilateral angle, the upright plate portion, faces the indoor side of the exterior wall panel 101. Similar to the lower fixing portion 2, the beam-mounted fixing device 21A has a long hole formed in the center of the upright plate portion and a fixing plate disposed therein.

[0044] However, the lower fixing part 2A is provided with an inward / outward movement adjustment member 25 made of a bolt or the like, which allows for adjustment of the inward / outward movement of the lower side of the exterior wall panel 101. A metal sliding plate 101a is provided on the back surface of the exterior wall panel 101, with which the tip side of the inward / outward movement adjustment member 25 comes into contact.

[0045] The upper side of the exterior wall panel 101 is connected to the upper steel beam 602 by an upper fixing part 3A, which is a sliding support. The upper fixing part 3A has a similar configuration to the upper fixing part 3, but is fixed to the underside of the upper steel beam 602 by welding. In addition, a metal sliding plate part 111 is provided on the back surface of the exterior wall panel 101, with which the access adjustment member 30 of the upper fixing part 3A comes into contact.

[0046] Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the illustrated embodiments. Various modifications and variations can be made to the illustrated embodiments within the same scope as the present invention or within an equivalent scope. [Explanation of symbols]
