Description

  The present invention relates to an improvement of a panel device called a so-called expansion joint that closes an end portion of a gap between a pair of buildings that are independently built in an adjacent state. Specifically, when considering the relative displacement between the two buildings in the event of an earthquake, a structure that can adopt a panel that can be used for lighting such as a glass panel, which has been considered difficult in the past, is realized. It is.

  In general, a gap between a pair of buildings that are built independently in an adjacent state is left as it is. On the other hand, for the purpose of improving the design of buildings in recent years and preventing garbage from being thrown away into the gap, it is possible to close the end of the gap with a panel device called an expansion joint. Proposed. However, the two buildings provided across the panel device move separately based on creeps such as earthquakes or strong winds, and even land subsidence. If it is simply installed in this, this panel device will be damaged in the event of an earthquake. When this panel device is configured to include glass, glass fragments fall during an earthquake or strong wind, which is dangerous. In consideration of these matters, conventionally, even when the panel device is provided, the panel device is configured by only a metal plate. For this reason, it is not possible to perform daylighting in the gap. As a result, when a conventional panel device is installed, even if a window is provided on the wall surface facing the gap in both of the above buildings, indoor lighting through the window cannot be performed. Although the structure which covers a roof surface part is described in patent documents 1-4, it cannot utilize in order to block the horizontal direction edge part of the said clearance gap.

  In light of the circumstances as described above, the present invention enables daylighting of light-transmitting synthetic resin panels such as glass panels, acrylics, and polycarbonates, taking into account the relative displacement between the buildings during an earthquake. It was invented to realize a structure that can adopt a simple panel.

In the panel device for closing a gap between buildings of the present invention, an end portion of a gap between a pair of buildings built in an adjacent state is provided between outer walls of these two buildings. It is to be closed by a panel that spans over.
In particular, the panel device that closes the gap between the buildings of the present invention includes a shaft, a pair of left and right first frame direction frames, a panel structure, and a neutral position return device.
Of these, the shaft is provided in a vertical direction on brackets fixed to the outer walls of the two buildings.
Further, both the first heel direction frame members are supported in a swingable manner around the respective heel shafts while being arranged in the vertical direction.

  In addition, the panel structure is supported by the first first-direction frame members so as to be movable in the horizontal direction. The panel structure includes a plurality of lateral frame members, a plurality of second heel direction frame members, and a panel. Each of the lateral frame members is coupled to the first frame direction frame members so as to be able to move in the horizontal direction in a state of being arranged in the horizontal direction. Moreover, each said 2nd heel direction frame material is arrange | positioned in the perpendicular direction in the state which couple | bonds each said said horizontal direction frame materials. The panel is supported by the lateral frame members and the second heel direction frame members.

  In order to support the panel structure as described above so as to be able to move in the horizontal direction on both the first heel direction frame members, for example, as described in claim 2, a plurality of pieces constituting the panel structure are provided. Among the horizontal frame members, at least a part of two horizontal frame members that are separated from each other in the vertical direction, the width of the opening portion is narrow and the width of the back portion is wide on the side surface facing the gap between the buildings. The engaging groove is provided in the horizontal direction. In addition, in the engaging groove, the tip portion of the guide member fixed to both the first frame direction frame members, the portion whose width in the vertical direction is wider than the proximal end portion can be moved only in the horizontal direction. Combine. And by this structure, the said panel structure is supported to the said both 1st heel direction frame material so that a movement of a horizontal direction is possible.

  The neutral position return device is for applying a force toward the neutral position to the panel structure. Such a neutral position returning device is constituted by a cam member and a support rod member as described in claim 3, for example. Of these, the cam member is fixed to the lower surface of any one of the horizontal frame members along the length direction of the horizontal frame member. The support rod member is supported by the first frame direction frame member. The lower surface of the cam member is a cam surface that is inclined in a direction in which the central portion in the length direction is at the uppermost position and gradually goes downward toward both ends in the length direction. The upper end portion of the support rod member is in contact with the cam surface. And when the panel structure exists in the neutral position, the installation positions of the cam member and the support rod member are regulated so that the upper end portion of the support rod member is positioned at the center in the length direction of the cam surface. . Further, in order to enable the operation of the neutral position return device as described above, the panel structure is supported so as to be movable up and down with respect to the bilateral frame material.

According to the panel device for closing a gap between the buildings of the present invention configured as described above, a panel capable of daylighting such as a glass panel while taking into account the relative displacement between the two buildings during an earthquake. The structure which can adopt is realizable.
In the event of an earthquake, the pair of first frame direction frame members supporting the left and right sides of the panel structure are displaced independently of each other (mainly relative to the horizontal direction) together with the buildings. In this state, the two frame-direction frame members are displaced relative to each other by oscillating around the frame axis or horizontally displaced with respect to the panel structure. Absorb. For this reason, it is possible to prevent an unreasonable force from being applied to the panel structure, regardless of the relative displacement between the first frame-direction frame members due to the independent movement of the two buildings. For this reason, it is possible to incorporate a panel capable of lighting such as a glass panel into the panel structure.

  1 to 11 show an example of an embodiment of the present invention. As shown in FIGS. 1 to 4, the structure of this example is a pair of buildings 1 that are independently built in an adjacent state, and the ends of gaps 2 between the two buildings, that is, both of these buildings 1. The discontinuous portions between the outer walls 3 and 1 are closed by a plurality of panel structures 4 and 4 spanned between the outer walls 3 and 3 of the buildings 1 and 1. In the example shown in the figure, both the buildings 1 and 1 are four-story buildings, and the panel structures 4 and 4 each have four in the vertical direction, each having a height dimension of one floor. Are arranged in series. The left and right ends of the panel structures 4 and 4 are supported on the outer walls 3 and 3 of the buildings 1 and 1, respectively, so as to be able to absorb displacement during an earthquake.

  For this reason, in the case of this example, both end portions of each panel structure 4, 4 are structured with respect to the outer walls 3, 3 of both buildings 1, 1 by the structure as shown in detail in FIGS. Supports swinging and horizontal displacement. For this purpose, a plurality of upper and lower brackets 5 are fixed to each of the outer walls 3, 3 at the horizontal ends of the outer walls 3, 3 of both buildings 1, 1. A first heel direction frame member 7 is swingably supported by a heel shaft 6 provided concentrically with each of the outer walls 3 and 3 in the vertical direction of each bracket 5. An elastic sealing material 8 is provided between the indoor side surfaces of the first first-side frame members 7 and the outdoor side surfaces of the two outer walls 3, 3. In this way, water tightness is maintained between the indoor side surface of each of the first heel direction frame members 7 and the outdoor side surfaces of the two outer walls 3 and 3.

  Then, as described above, the panel structures 4, 4 are respectively mounted on the outdoor side surfaces of the first frame direction frame members 7, which are swingably supported on the outer walls 3, 3 of the both buildings 1, 1. Both ends of the are supported so as to be movable in the horizontal direction. As shown in FIGS. 5, 6, 8, 9, and 10, each of these panel structures 4 and 4 includes an upper frame 9 (see FIGS. 1, 2 and 10) and a lower frame 10 ( 1 and FIG. 1 are omitted), a pair of left and right ridge frames 12 and 12 (FIGS. 1 and 3), each of which is a second heel direction frame material. 6) and glass panels 13 and 13. The horizontal ends of the upper frame 9, the lower frame 10, and the invisible eyes 11, 11 abut against the opposite side surfaces of the two frame frames 12, 12 arranged in the vertical direction, respectively. The two frame frames 12 and 12 are coupled and fixed by tapping screws or coupling brackets. And the peripheral part of each said glass panel 13 and 13 is supported by each said frame 9, 10, 12 and said each invisible 11 and 11, and each said panel structure 4 and 4 is comprised. Each of these members 9 to 12 is made of an integrally extruded material of aluminum alloy. In addition, a part of both the first heel direction frame members 7 is a portion that is deviated in the vertical direction from each of the meshes 11, 11 (in the vertical direction, the upper frame 9, the lower frame 10, and the The portion between the eyes 11 and 11 is extended to the side opposite to the gap 2 (lower than FIGS. 3, 4, and 6) as necessary, and is brought close to and opposed to the glass panels 13 and 13. And this extended part is abutted on these glass panels 13 and 13 via a sliding material, and the glass panels 13 and 13 are backed up.

  In the case of this example, in order to support each panel structure 4, 4 configured in this way on the outdoor side surface of both the first heel direction frame members 7, 7 in the horizontal direction, FIG. The structure as shown in -7 is adopted. That is, each of the panel structures 4 and 4 that constitute the panel structures 4 and 4 is a part of the upper and lower two pieces 11 and 11, and a gap between the buildings 1 and 1. 2 is provided in the horizontal direction with an engaging groove 14 having a narrow opening and a wide back. Further, in the engaging groove 14, a portion of the distal end portion of the guide member 15 fixed to the first first-direction frame members 7 and 7 whose width in the vertical direction is wider than the proximal end portion is defined in the horizontal direction. Is engaged so that only the movement of can be performed.

  In order to provide the guide member 15, an L-shaped second bracket 16 is screwed and fixed to the side surfaces of the first first-direction frame members 7 and 7, and the guide member 15 is screwed to the second bracket 16. I support it. In addition, the part which contact | abuts to the side surface of each said seamless 11 and 11 among this 2nd bracket 16 is made into the partial arc-shaped convex surface, and contact | abutted with these 2nd bracket 16 and the side of each seamless 11 and 11 The part does not hinder the swinging of the panel structures 4, 4 with respect to the first frame direction frame members 7, 7. With such a configuration, the panel structures 4 and 4 are supported by the first frame direction frame members 7 and 7 so as to be able to swing and move in the horizontal direction. In addition, stoppers 17 and 17 are fixed at positions where a portion of the engagement groove 14 where the guide member 15 is engaged is sandwiched from both sides, so that the panel structures 4 and 4 The first frame direction frame members 7 and 7 are prevented from moving excessively in the horizontal direction. Such a structure for supporting each panel structure 4, 4 so as to be swingable and horizontally movable with respect to both first frame direction frame members 7, 7 is as follows. At least four locations are provided for each of the panels, ie, at both ends of the pair of upper and lower eyes 11, 11 provided in the panel structures 4, 4.

  Further, for each of these panel structures 4, 4, between the lower surfaces of both end portions of any one of the above-described lateral frame members and the first frame direction frame members 7, 7. 7 to 8, two sets of neutral position return devices 18 are provided for each of the panel structures 4 and 4. The neutral position return device 18 applies a force to the panel structures 4 and 4 toward the neutral position (appropriate position when no earthquake occurs). Such a neutral position return device 18 includes a cam member 19 and a support rod member 20. Of these, the cam member 19 is fixed to the lower surface of any one of the above-mentioned horizontal frame members, which is any one of the horizontal frame members, along the length direction of the seamless frame 11. ing. The support rod member 20 is supported by the first bracket direction frame members 7 and 7 by a third bracket 21.

  In the case of this example, the support rod member 20 is a bolt screwed into the tip of the third bracket 21 from below. Further, the lower surface of the cam member 19 is a cam surface 22 that has a central portion in the length direction at the uppermost position and is gradually inclined downward toward the both ends in the length direction. The upper end portion of the support rod member 20 abuts against the cam surface 22. And when each said panel structure 4 and 4 exists in a neutral position, the upper end part of the said support rod member 20 is located in the length direction center part of the said cam surface 22, ie, the part which exists in the uppermost position. Thus, the installation positions of the cam member 19 and the support rod member 20 are restricted. Further, in order to enable the operation of the neutral position return device 18 as described above, as shown in FIG. 7, a long hole in the vertical direction is formed in the flange portion of the guide member 15 in the second bracket 16. 23 is inserted. Accordingly, the panel structures 4 and 4 are supported so as to be able to be lifted and lowered slightly with respect to the first frame direction frame members 7 and 7.

  According to the panel device for closing the gap between the buildings of the present invention configured as described above, the glass panels 13 and 13 that can be lit while taking into account the relative displacement between the two buildings in the event of an earthquake. Can be adopted. That is, the end of the gap 2 is closed with the panel structures 4 and 4 including the glass panels 13 and 13 for the purpose of improving the design of the building street and preventing dust and the like from being thrown away into the gap. As a result, if a window is provided on the wall facing the gap 2 between the two buildings 1 and 1, the inside can be daylighted through the window. Moreover, if the glass panels 13 and 13 which comprise each said panel structure 4 and 4 are built in an opening-and-closing type, ventilation can also be performed as needed.

  In the event of an earthquake, as shown in FIG. 4, a pair of first frame direction frame members 7, 7 that support the left and right sides of each panel structure 4, 4, At the same time, they are displaced independently of each other (primarily in the horizontal direction). In this state, the first heel direction frame members 7, 7 swing around the heel shaft 6, or the panel structures 4, 4 move the engagement groove 14 and the guide member 15. Is displaced in the horizontal direction with respect to both the first heel direction frame members 7, 7. And, by these swinging displacement and horizontal movement, the relative displacement between these first first-direction frame members 7 and 7 is absorbed. For this reason, an unreasonable force is applied to each of the panel structures 4 and 4 regardless of the relative displacement of the first frame direction frame members 7 and 7 due to the independent movement of the buildings 1 and 1. You can prevent things. The watertightness between the panel structures 4 and 4 and the outer wall 3 is maintained by a seal lip 24 (see FIGS. 5 to 6) made of an elastic material supported by the panel structures 4 and 4.
