JP-A-8-189155 Japanese Utility Model Publication No. 59-182541

  In the conventional technology of Patent Document 1, when each housing is a slab that partitions the upper space and lower space of a building, each upper surface facing the upper space of each housing forms a horizontally continuous floor by grating. In addition, an opening that allows a passer-by to easily recognize from below is formed between the lower surfaces of the lower layers of each housing, and the appearance of the design is lowered, and the watertightness of the drainage device is lowered. There is a problem that water leaks to the lower space and soils the floor.

  Further, in the prior art of Patent Document 2, water leakage such as rainwater is led directly or drained by a water return plate into the basket, and the basket is connected to a handrail panel by a basket supporter. The sliding panel is connected to the overhanging material, and the overhanging material is provided so as to protrude from the side of the roof panel of the house, and for each frame that is a slab separating the upper space and the lower space of the building, the wall and the roof panel are Relative displacement in the left-right direction, the front-rear direction perpendicular to the left-right direction, and the up-down direction is allowed, and a gap that opens on the ceiling surface cannot be closed, so that it cannot be used as a telescopic cover device for a ceiling.

  An object of the present invention is to provide a ceiling extendable cover device that allows a relative displacement between the respective enclosures to close a gap and collects water leaking in the gap.

In the present invention, each frame of two adjacent buildings is opposed to each other with a gap, and allows relative displacement in the left-right direction, the front-rear direction perpendicular to the left-right direction, and the up-down direction. An expansion / contraction cover device for a ceiling that maintains a state in which a gap between each housing is closed from below,
A cover body whose one end is rotatably held around a rotation axis parallel to the front-rear direction on one housing, and whose other end is in contact with the lower surface of the other housing;
A support portion fixed to one housing and supporting one end portion of the cover body so as to be rotatable about the rotation axis; and the other end portion is supported in a state where the one end portion of the cover body is supported by the support portion. An expansion / contraction cover device for a ceiling including an edge member provided with an abutting portion that prevents rotation of the cover body in a direction of downward displacement.

  According to the present invention, the edge member is fixed to one housing. The edge member has a support portion and a contact portion, and the support portion supports one end portion of the cover body so as to be rotatable around the rotation axis, and the one end portion of the cover body abuts on the contact portion. Thus, the rotation of the cover body in the direction in which the other end portion is displaced downward is prevented. Since the cover body has a concave cross section, the cover body is prevented from flowing out from both ends in the left-right direction, and water leaking in the gap is accommodated in the cover body. The leaked water accommodated in the cover body is guided to drainage facilities such as an existing sewer pipe and drainage groove by a drainage water guiding facility realized by a drain pipe, for example, and drained.

  The drainage is mainly rainwater, water sprinkling and dew condensation water when the upper space above each enclosure is outdoors, and mainly spilled water, drinking water and dew condensation water when the upper space is indoors. In addition, it includes coins dropped by passers, small items such as writing instruments, solids such as garbage and sand, and these are collectively referred to as “leakage”. In addition, the left and right direction and the front and rear direction are slightly inclined with respect to the horizontal direction due to each direction parallel to the two axes orthogonal to each other on the horizontal plane parallel to the still water surface, as well as uneven settlement of the ground and construction errors of the building. A substantially horizontal direction including a direction.

  When a sudden earthquake occurs, each frame is relatively displaced in the left-right direction, the front-rear direction, and the up-down direction. Such relative displacement is almost always generated as a combined three-dimensional displacement in which displacements in the three directions of the left-right direction, the front-rear direction, and the up-down direction are actually used as the displacement components in each direction. Therefore, the cover body is supported at one end portion so as to be rotatable around a rotation axis parallel to the front-rear direction by the support portion with respect to the edge member, and the other end portion is in contact with the lower surface of the other casing, Even if the cover body follows one housing together with the edge member and is displaced relative to the other housing, the cover body is allowed to be displaced in the left-right direction, the front-rear direction, and the up-down direction relative to the other housing. Leakage that has fallen in the air gap without sacrificing aesthetics, maintaining the continuity of the ceiling surface in appearance and maintaining the air gap closed from the bottom. The leakage of water from the gap to the lower space is prevented.

  Further, since the rotation of the cover body in the direction in which the other end of the cover body moves downward is prevented by the contact portion of the edge member, the other end of the cover body is separated from the lower surface of the other housing in the downward direction. The cover body is prevented from tilting. Thereby, a gap is not generated between the other end of the cover body and the lower surface of the other casing, and the gap can always be kept closed without impairing the continuity of the ceiling surface between the casings. .

In the present invention, a first guide member extending in the left-right direction is fixed to the other casing,
A second guide member that is movably engaged with the first guide member in the left-right direction while being accommodated in the cover body is fixed to the cover body.
The supporting portion of the edge member supports one end of the cover body so as to be rotatable around the rotation axis and movable along the rotation axis.

  According to the present invention, the first guide member is provided on the other casing, the second guide member is provided on the cover body, and the first and second guide members are movably engaged in the left-right direction. Therefore, even if each housing has a large space in the left-right direction through the gap, and a wide cover body is adopted between the housings corresponding to the space, even if the shape of the cover body increases, Even if an excessively large load is not borne and the space in the left-right direction between the respective housings is increased, the gap can be reliably closed by the cover body, and water leakage in the gap can be accommodated in the cover body. In addition, the leaked water accommodated in the cover body is led to drainage facilities such as existing sewer pipes and drainage grooves and discharged by drainage water guiding equipment realized by, for example, drain pipes or drainage pipes, as described above. .

  Since one end portion of the cover body is movable along the rotation axis with respect to the support portion of the edge member, relative displacement in the front-rear direction between the housings can be allowed, and the cover body's own weight and contained water leakage It is possible to allow the cover body to bend due to the weight of the cover body and the relative displacement in the vertical direction between the housings, thereby reducing the excessive bending load acting on the cover body and preventing the cover body from being deformed or damaged. The

  Further, according to the present invention, a plurality of cover bodies are arranged adjacent to each other in the front-rear direction, and each end portion facing each other in the front-rear direction is connected by an auxiliary cover body that is watertightly attached to each end portion. It is characterized by that.

  According to the present invention, since the plurality of cover bodies are connected in a watertight manner by the auxiliary cover body, with a simple configuration without significantly changing the configuration of the ceiling extendable cover device, the gap extending over a long section in the front-rear direction is blocked, Maintaining the continuity of the ceiling surface between the housings, the horizontal displacement, the front-rear direction, and the vertical displacement of each housing can be allowed.

  According to the present invention, even if each housing is relatively displaced in the left-right direction, the front-rear direction, and the up-down direction due to the occurrence of a sudden earthquake, the cover body is rotatably supported at one end by the edge member, and the other end Is in contact with the lower surface of the other housing, so that the cover body follows the one housing together with the edge material and is displaced relative to the other housing even when the cover body is displaced in the left-right direction, the front-rear direction, and the vertical direction. Displacement in the direction is allowed, the gap is kept closed from the bottom, the continuity of the ceiling surface is obtained in appearance, and the water leaked in the gap is collected without impairing the aesthetics. It is prevented that water leaks into the lower space below the housing. Further, since the rotation of the cover member in the direction in which the other end of the cover body moves downward is prevented by the contact portion of the edge member, the cover body is prevented from being inclined due to its own weight or the weight of the leaked water contained therein. It is possible to prevent a gap between the other end of the first casing and the lower surface of the other casing from being generated, and to maintain a state where the gap is always closed without impairing the continuity of the ceiling surface between the casings.

  According to the invention, the first guide member is provided on the other housing, the second guide member is provided on the cover body, and the first and second guide members are engaged with each other so as to be movable in the left-right direction. Therefore, even if each frame has a large space in the left-right direction through the gap, and a wide cover body is adopted between the housings corresponding to the space, the support portion of the edge member can be used even if the shape of the cover body is increased. It is possible to follow the displacement in the front-rear direction without applying an excessively large load to the cover body and bringing the cover body into contact with the housing. Therefore, even if the space in the left-right direction between the housings is increased, the gap can be reliably closed by the cover body, and water leakage in the gap can be accommodated in the cover body. In addition, the leaked water accommodated in the cover body is led to drainage facilities such as existing sewer pipes and drainage grooves and discharged by drainage water guiding equipment realized by, for example, drain pipes or drainage pipes, as described above. .

  Since one end portion of the cover body is movable along the rotation axis with respect to the support portion of the edge member, relative displacement in the front-rear direction between the housings can be allowed, and the cover body's own weight and contained water leakage It is possible to allow the cover body to bend due to the weight of the cover body and the relative displacement in the vertical direction between the housings, thereby reducing the excessive bending load acting on the cover body and preventing the cover body from being deformed or damaged. The

  Furthermore, according to the present invention, since the plurality of cover bodies are watertightly connected by the auxiliary cover body, the gap extending over the long section in the front-rear direction can be closed with a simple configuration without greatly changing the configuration of the ceiling extension cover device. By maintaining the continuity of the ceiling surface between the housings, the relative displacement of the housings can be allowed.

The The guide member 107 includes an attachment piece 109 that comes into contact with the lower surface 7b of the other housing 3b from below, and a guide piece 110 that is bent at a right angle from one end in the front-rear direction X2 of the attachment piece 109.

  The attachment piece 109 is formed with a plurality of (two in this embodiment) long holes 111 extending in the front-rear direction X2. The guide piece 110 includes a first guide portion 112 having a first protrusion amount H1 downward from the attachment piece 109, a second guide portion 113 having a second protrusion amount H2 larger than the first protrusion amount H1, and a first guide portion 110. The protrusion amount changes from the protrusion amount H1 to the second protrusion amount H2, and includes a first guide portion 112 and a third guide portion 114 interposed between the second guide portions 113.

  The first guide portion 112 is formed with a first guide surface 116 that is inclined upward as it approaches the packing 60 at a corner 115 facing the packing 60 at a lower edge portion facing downward. A second guide surface 117 extending in parallel with the attachment piece 109, that is, in parallel with the left-right direction X <b> 1 is formed in a direction away from the packing 60 than the surface 116. The second guide surface 117 is formed by retracting upward from the height position of the packing fitting portion 54. The first protrusion amount H1 is a distance from the upper surface of the mounting piece 109 to the second guide surface 117 perpendicularly.

  The second guide portion 113 is formed with a third guide surface 120 facing downward and parallel to the upper surface of the mounting piece 109 so as to protrude downward from the height position where the packing fitting portion 54 is formed. . The second protrusion amount H2 is a distance from the upper surface of the mounting piece 109 to the third guide surface 120 perpendicularly.

  Further, the third guide portion 114 is connected to the third guide surface 120 of the second guide portion 113 from the second guide surface 117 of the first guide portion 112, toward the second guide portion 113 from the first guide portion 112. Thus, a fourth guide surface 121 is formed that is inclined downward, that is, in a direction away from the attachment piece 109 downward.

  As described above, in the guide member 107 fixed to the other housing 3b, the guide piece 110 has the first to third guide portions 112, 113, and 114, and the guide portions 112, 113, and 114 have the first portion. Since the fourth guide surfaces 116, 117, 121, and 120 are formed, the first guide portion 115 presses the packing 60 by the first guide surface 116 when the housings 3a and 3b are relatively displaced in the approaching direction. The gasket 60 is inserted between the packing fitting portion 54 and the lower surface 7b of the other housing 3b, and the packing 60 is guided while being kept pressed down by the second guide surface 117 as it is relatively displaced in the approaching direction. The member 107 is allowed to move, and the packing fitting portion 54 is pushed down together with the packing 60 by the fourth guide surface 121, so that the packing 60 rides on the third guide surface 120. The state.

  As a result, in the relative displacement in the left-right direction X1 between the housings 3a and 3b, the cover body 8 is rotated by the angle corresponding to the second protrusion amount H2 in the direction in which the other end portion is separated from the lower surface 7b of the other housing 3b. By rotating around the movement axis m, the collision between the cover body 8 and the other housing 3b is reliably avoided. Further, when the respective housings 3a and 3b are displaced relative to each other in the direction opposite to the above, the packing 60 and the packing fitting portion 54 are connected to the third guide surface 120, the fourth guide surface 121, and the second guide surface of the guide member 107. The cover body 8 is guided while sliding in this order on the guide surface 117 and the first guide surface 116, and the cover body 8 has an angle in the direction opposite to the rotation direction at the time of relative displacement around the rotation axis m. Displaces and returns to the original horizontal state.

  In the fore edge block 100, the end wall portion 105 of the fore edge block 100 is arranged on the side of each housing 3 a and 3 b with respect to the guide member 107 with respect to the guide piece 110 of the guide member 107. Therefore, in the relative displacement in the front-rear direction X2 of each housing 3a, 3b from the initial installation state where the end wall portion 105 and the guide piece 110 are in contact with each other, one housing 3a is on one side with respect to the other housing 3b ( When displaced to the left in FIG. 5, the end wall portion 105 abuts on the guide piece 110 in the same direction, so that the displacement of the cover body 8 in the same direction is prevented by the guide member 107. As a result, the first hinge piece 55 of the cover body 8 moves in the same direction along the rotation axis m with respect to the second hinge piece 79 of the edge member 11, and relative displacement on one side in the front-rear direction X2 is allowed. Is done.

  Further, when the housings 3a and 3b are relatively displaced on the other side (right side in FIG. 5) in the relative displacement in the front-rear direction X2, the end wall portion 105 of the fore edge block 100 is separated from the guide piece 110 of the guide member 107, Relative displacement to the other side is allowed in the range of the interval ΔL parallel to the front-rear direction X2 until the fore edge block 100 contacts the outer wall 35b of the other building B. In this way, the relative displacement in the front-rear direction X2 of each housing 3a, 3b can be allowed.

  FIG. 6 is an enlarged cross-sectional view taken along section line VI-VI in FIG. One end in the longitudinal direction along the front-rear direction X2 of the edge member 11 and the cover body 8 is water-tightly closed by an end plate 130 having an inverted L-shaped cross section. Further, the packing 60 is attached to the end plate 130 of the cover body 8 so as to be connected to the packing fitting portion 54, and the packing 60 is elastically brought into contact with the lower surface 7b of the other housing 3b to ensure water tightness. At the same time, one end of a drain pipe 131 bent in an L-shape for discharging water leaked in the cover body 8 to the outside is connected and communicated through a through hole 132 formed in the end plate 130. ing. The leaked water accumulated in the cover body 8 is guided to the drainage pipe 131 through the through hole 132, and is guided to a drainage facility such as an existing drainage groove by a drainage pipe (not shown) to be discharged.

  7 is a plan view of the joint portion 140 of the cover body 8 as viewed from above, and FIG. 8 is a cross-sectional view of the joint portion 140 as viewed along the section line VIII-VIII in FIG. A plurality of cover bodies 8 adjacent to each other in the front-rear direction X2 are disposed. End portions of the cover bodies 8 facing the front-rear direction X2 are in contact with each other, and are fitted in a watertight manner with a sheet-like seal member 143 over the respective end portions. The auxiliary cover body 144 is connected. The auxiliary cover body 144 has a concave cross section, and both side walls are fixed to the cover bodies 8 with screws 145 and 146.

  Since the plurality of cover bodies 8 are water-tightly connected by the auxiliary cover body 144, a simple configuration without greatly changing the configuration of the ceiling extendable cover device 1 is used to block the gap extending over a long section in the front-rear direction X2. The continuity of the ceiling surface between 3a and 3b can be maintained, and relative displacement in the left-right direction X1 and the front-rear direction X2 and the vertical direction Y of each housing 3a, 3b can be allowed. In addition, when the width in the front-rear direction X <b> 2 of each housing 3, 3 b is not so large, only the single cover body 8 may be used without using the auxiliary cover body 144.

  As described above, according to the present embodiment, the edge member 11 is fixed to one of the housings 3a, and the edge member 11 includes the support portion 9 and the contact portion 10, and the cover portion is covered by the support portion 9. One end portion of the cover body 8 is supported so as to be rotatable about the rotation axis m, the one end portion of the cover body 8 is in contact with the contact portion 10, and the other end portion of the cover body 8 is rotated in a direction to be displaced downward. Movement is blocked. Since the cover body 8 is formed to have a concave cross section, it is possible to prevent water leaking in the cover body 8 from flowing out from both ends in the left-right direction X1, and to ensure that water leaking in the gap G falls into the cover body 8. And drained from the drain pipe 131. Therefore, the cover body 8 may be installed so that the end on the drainage pipe 131 side has a drainage gradient inclined downward from the end on the side of each housing 3a, 3b, or falls into the cover body 8. When the flow rate of the leaked water is very small, it may be installed horizontally.

  When a sudden earthquake occurs, the housings 3a and 3b are relatively displaced in the left-right direction X1, the front-rear direction X2, and the up-down direction Y. In practice, such a relative displacement is almost always generated as a combined three-dimensional displacement in which displacements in the three directions of the first and front-rear direction X2 and the up-down direction Y are displacement components in each direction. Therefore, one end of the cover body 8 is supported by the support portion 9 with respect to the edge member 11 so as to be rotatable around a rotation axis m parallel to the front-rear direction X2, and the other end is the lower surface of the other housing 3b. Even if the cover body 8 follows the one housing 3a together with the edge member 11 and is relatively displaced with respect to the other housing 3b, the left and right direction X1 of the cover body 8 with respect to the other housing 3b, the front-rear direction X2 and displacement in the vertical direction Y are allowed, the cover body 8 is prevented from being broken by interference with the other housing 3b, the gap is kept closed from the bottom, and each housing 3a, The continuity of the ceiling surface realized by the lower surfaces 7a and 7b of 3b and the lower surface of the cover body 8 is obtained, and the water leaked in the gap is collected without impairing the beauty, and the water leaks from the gap to the lower space 12 End up Theft can be prevented.

  Further, since the contact portion 10 of the edge member 11 prevents the other end portion of the cover body 8 from moving downward, the other end portion of the cover body 8 is separated from the lower surface 7b of the other housing 3b. The cover body 8 is prevented from inclining in the direction of separating downward. As a result, a gap is not generated between the other end of the cover body 8 and the lower surface 7b of the other casing 3b, and the gap G is always blocked without impairing the continuity of the ceiling surface between the casings 3a and 3b. Can be maintained in a state.

  The other housing 3b is provided with a guide member 107 as a first guide member, and the cover body 8 is provided with a fore edge block 100 as a second guide member. The guide member 107 and the fore edge block 100 are arranged along the left-right direction X1. Since the housings 3a and 3b are engaged with each other in the front-rear direction X2, the spacing between the housings 3a and 3b is large between the housings 3a and 3b. Even if the shape of the cover body 8 is increased by adopting 8, the weight of the cover body 8 can be applied without imposing an excessively large load on the support portion 9 of the edge member 11. Therefore, even if the space | interval of the left-right direction X1 between each housing 3a, 3b becomes large, the space | gap G can be reliably closed by the cover body 8, and the water leak in the space | gap G can be accommodated in the cover body 8. FIG.

  In another embodiment of the present invention, the first and second guide members are not limited to the guide member 107 and the fore edge block 100 described above. For example, an end plate made of a flat plate is welded to the length of the cover body. Other forms such as bonding so as to close both ends in the direction may be adopted.

  Furthermore, since the one end part of the cover body 8 can move along the rotation axis m by the first and second hinge pieces 55 and 79 with respect to the support part 9 of the edge member 11, between the respective housings 3 a and 3 b. The relative displacement in the front-rear direction X2 can be allowed, the deflection of the cover body 8 due to the weight of the cover body 8 and the weight of the leaked water and the relative displacement in the vertical direction Y between the housings 3a and 3b can be allowed. As a result, the excessive bending load acting on the cover body 8 can be mitigated, and deformation and breakage of the cover body 8 can be prevented.

  Further, since the plurality of cover bodies 8 are watertightly connected by the auxiliary cover body 144, the gap G extending over a long section in the front-rear direction X2 with a simple configuration without greatly changing the configuration of the ceiling extension cover device 1. And maintaining the continuity of the ceiling surface between the housings 3a, 3b, and allowing relative displacement in the first and front-rear direction X2 and the vertical direction Y of the housings 3a, 3b.
