Description

TECHNICAL FIELD The present invention relates to a waterproof device that is provided to close a clearance formed at a connection site when one structure and another structure are connected.

When connecting one structure (for example, a fixed structure such as a building) with another structure (for example, a movable structure such as a walkway), conventionally, the clearance between the walls is Since the amount of water is small, waterproofing was done using rubber plates, etc.

However, when a large clearance is formed, simply installing a thin rubber plate, etc. will not allow one structure to shake relative to the other during an earthquake, and the positional displacement of the other structure will cause the clearance to deteriorate. There is a risk that the width of the bridge will change, and the resulting change will not be able to withstand the load, etc., or that a gap will open.If a thick rubber plate is installed, there is a risk that the position of the crossing path will be obstructed. At the same time, there was a problem of spoiling the aesthetic appearance.

For example, there is a slight gap (not clear in the drawing) between the outer walls 7a, 7a of the passageway 4 shown in FIG. 4 of Patent Document 1 and the inner wall 4d (inner wall shown in the sectional view) of the building 3 on the left. Although such a gap (clearance) can be waterproofed with a rubber plate or the like, if the clearance has to be increased due to specifications, the above-mentioned problem occurs.
Note that this patent document does not include a waterproofing device that is related to the present invention, and this patent document is cited for convenience in understanding the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to embodiments for carrying out the invention shown in the drawings.
In a first embodiment of the present invention shown in FIGS. 1 to 9, 1 is a space between a wall surface 3a of one structure 3 and a wall surface 4a of the other structure 4 provided through a clearance 2. This is a waterproofing device for a structure that closes the clearance 2 and prevents rainwater etc. from entering.

In this embodiment, the first structure 3 (fixed structure, for example, one building) and the third structure 11 (for example, the other building) connect these structures to the joint between them. A second structure 4 (a movable structure that swings relative to the fixed structure during an earthquake, such as an expansion joint such as a walkway) is provided, and the first structure and the second structure The waterproofing device 1 of the present invention is provided between objects.

Note that the left-right direction is the left-right direction (the longitudinal direction of the other structure 4) in FIG. ), the vertical direction refers to the vertical direction in FIG.

Furthermore, in the present invention, a structure refers to a building such as a frame, a building, a road, a slab, an elevator shaft, an escalator, a breezeway, an expansion joint, and the like.

As shown in FIGS. 1 to 4, for example, the waterproofing device 1 of the present invention includes a telescopic panel 5 whose one end is attached to the one structure 3, and a waterproofing panel 5 which is attached to the other end of the telescopic panel 5. It consists of a seal 6 and a biasing means 7 that biases the waterproof seal 6 so that it always comes into contact with the wall surface 4a of the other structure 4.

In this embodiment, one structure 3 is a building such as a building, and a connecting portion 8 to which the other structure 4 is connected is formed on one side of this one structure 3 . This connecting portion 8 is formed in a size that allows insertion of the other structure 4, and its longitudinal dimension is larger than the longitudinal dimension of the other structure 4. The clearance 2 formed in the front-rear direction when the object 3 is connected to the other structure 4 is closed by the waterproofing device 1 of the present invention to prevent rainwater from entering.

A support part 9 that supports the protruding end of the other structure 4 is formed on the floor surface of this connection part 8, and a guide member 10 extending in the left-right direction is provided on this support part 9. There is. The length of this support part 9 is formed to be more than twice the width of shaking caused by an earthquake.

In this embodiment, the other structure 4 is provided between the one structure 4 and the third structure 11 (joint part C), and connects the one structure 4 and the third structure 11. It is a passage-like structure (expansion joint), and the passage portion is formed into a substantially rectangular shape in cross-section. This other structure 4 has one end supported by a support portion 11a formed on the third structure 11 so as to be rotatable in the front and back direction about the mounting member 12, and has a protruding end side (another end side). ) is supported by one structure 3 so as to be slidable in the left-right direction via a rolling member 13 that enters the connecting portion 8 of one structure and engages with the guide member 10 . Therefore, in the event of an earthquake, one end is displaced in the front-back direction together with one of the structures 3 when the structure 3 swings in the front-back direction, and the other end rotates around the rolling member 13 engaged with the guide member 10 as a fulcrum. In addition, it swings in synchronization with the third structure 11 when swinging in the left-right direction. Note that gaps between the opening of the third structure 11 and the one end side of the other structure 4 and the outer wall of the other structure 4 and the inner wall of the one structure 3 and the floor surface etc., are closed by appropriately using a known joint device E that can follow and absorb the shaking motion of an earthquake.

By the way, this other structure 4 may be formed of concrete or the like, or may be formed by forming a frame of aggregate, steel pipe, etc., and fixing panels or the like to the outer and inner surfaces. It is not limited to a specific configuration.

As shown in FIG. 5, the expandable panel 5 includes a plurality of panel bodies 14, at least some of which are overlapped with each other in a substantially abutting state, and at least some of the adjacent panel bodies 14 have a thickness equal to or less than the thickness of the panel body 14. and a holding means 15 for holding it so that it is always in substantially abutting state in the direction.

In this embodiment, the plural panel bodies 14 include one panel body 14a whose one end is attached to the one structure, the other panel body 14b, and the one panel body 14a and the other panel body 14b. An intermediate panel main body 14c provided between them is used, and the waterproof seal 6 is attached to the other end side (the other structure 4 side) of the other panel main body 14b.

The panel body 14 is a metal plate having a substantially flat plate shape, a substantially crank shape, a substantially angle shape, or a substantially U-shape in plan view, and is located between one end side of one panel body 14a and one structure 3, or on one side. It is desirable to apply waterproofing treatment, such as providing a rubber plate, to the approximate contact portion between the panel main body 14a and the other panel main body 14b. In this embodiment, one panel main body 14a is formed into a substantially U-shape, the middle panel main body is formed into a substantially crank shape, and the other panel main body is formed into an angle at one end and a substantially crank shape at the other end. ing. Note that it is desirable that seal portions 14d are provided at both ends of each panel body 14 so as to substantially abut with the adjacent panel bodies 14 in a substantially surface contact state or a substantially line contact state. Additionally, it is desirable that the seal portion 14d is provided with a member that does not hinder the sliding movement of the panel body 14 and can be waterproofed. The expression that adjacent panel bodies 14 are in approximate contact includes that only the seal portion 14d is in approximate contact with the adjacent panel body 14, and the term substantially in contact with each other includes not only a state in which they are in contact but also a slight contact with each other. This also includes a state in which they are close to each other with a large gap between them.

The waterproof seal 6 is attached to the other end side (the other structure 4 side) of the other panel main body 14b, and this waterproof seal 6 is constantly pressed against the wall surface of the other structure 4 by the biasing means 7. This prevents rainwater, etc. from entering.

By the way, it is desirable to provide a rubber plate or the like in the vertical gap between the other structure 4 and one structure 3 (or the rail member 16) to perform waterproof treatment. Even in the event of an earthquake, the other structure 4 hardly shifts its position in the vertical direction, so performing such a waterproofing treatment can prevent rainwater from entering. Note that if only a small gap occurs, it is sufficient to install a rubber plate, etc.; however, if a certain amount of gap occurs, install a metal plate, etc. made of the same material as the panel body 14, and then It is desirable to provide a rubber plate or the like between the metal plate or the like and the other structure 4 for waterproofing.

Moreover, it is desirable to provide the waterproof seal 6 on the back surface of the other end of the other panel main body 14b, with a slight gap between the surface of the other panel main body 14b and the other structure 4. It is desirable that the contact point be approximately in contact with the contact point. With this configuration, the surface (the part that can be observed from the outside) is covered with a stretchable panel, and the aesthetic appearance can be improved.

The holding means 15 is provided as a pair of upper and lower parts near the connecting portion 8 of the one structure 3, and is provided at least between the one panel main body 14a and the intermediate panel main body 14c, and the intermediate panel main body 14c and the other panel main body 14b. A rail member 16 that can be engaged so that a portion thereof is in a substantially abutting state (combined state), the one panel body 14a and the intermediate panel body 14c, and the intermediate panel body 14c and the other panel body 14b. The locking portions 17 are provided at each end and restrict sliding so that the substantially abutting state is released.

The rail member 16 is provided with a guide portion (not shown), such as a window frame, so that one panel body 14a, the intermediate panel body 14c, and the other panel body 14b can each slide in the front and back direction. Guided portions (not shown) are formed at the upper and lower ends of the panel body 14 so as to engage with the guide portions.

In the present embodiment, the locking portion 17 limits the sliding movement of the panel body 14 so that the folded portions of the ends of the panel body 14 come into contact with each other and are locked with each other so that they are in a substantially abutting state at all times. . As a result, since one panel body 14a is fixedly attached to one structure 3, it swings in synchronization with one structure 3 during an earthquake, and the other panel body 14b is always attached to the other structure 3 by the biasing means. It comes into contact with the structure 4 of. When the other panel body 14b is displaced by a predetermined amount or more toward the other structure 4, the locking portion 17 of the other panel body 14b and the locking portion 17 of the intermediate panel body 14c are in contact with each other. Therefore, by sliding the intermediate panel main body 14c toward the other structure 4, it is possible to hold at least a portion of the adjacent panel main bodies 14 so that they are substantially in contact with each other in the thickness direction of the panel main bodies 14. can. Note that if you want to make the intervals between the panel bodies 14a, 14b, and 14c equal, they can be biased by coil springs or the like with the same spring force, so that even when the intermediate panel body 14c slides, the panel bodies 14 do not touch each other. It is possible to maintain approximately equal intervals.

Note that the holding means 15 may be used as long as it can limit the sliding range of the panel bodies 14 and hold the adjacent panel bodies 14 so that they are always substantially in contact with each other, such as a locking pin or the like on the rail member 16. It is also possible to provide a configuration in which the panel bodies 14 come into contact with the locking pins, thereby limiting the sliding range so that the adjacent panel bodies 14 are always in substantially abutting state, or by providing a rail member 16. First, the pivot portion of a pantograph-shaped link member and the panel main body 14 may be connected, and the movements of the link member and the link member may be synchronized so that adjacent panel main bodies 14 are always in a substantially abutting state.

The waterproof seal 6 includes a seal member 18 attached to the other end of the other panel body 14b, and a sliding member 19 provided on the side surface of the seal member 18 that substantially contacts the other structure. ing. This sealing member 18 is made of a resin such as rubber or silicone which is thicker than the panel body 14, and the side surface connected to the other panel body 14b is constantly pressed by the biasing means 7. ing. This sealing member 18 may be a pipe-shaped (hollow) member made of metal, resin, etc., with resin such as rubber or silicone fixed on the surface, and is in contact with the outer wall of the other structure 4 to prevent water from leaking out. The shape and material are not limited to those of this embodiment, as long as the shape and material can prevent intrusion.

Further, the sliding member 19 is a roller-shaped member made of resin such as rubber or silicone, and is in contact with the entire wall surface 4a of the other structure 4 in a substantially linear contact state, and the sealing member 18 and the other structure 4 It is designed to close the tiny gap between the By providing such a sliding member 19, it is possible to reliably prevent rainwater etc. from entering between the other panel main body 14b and the other structure 4, and also to smoothly follow the shaking movement caused by an earthquake. be able to. Note that a sealing material such as water stopper rubber may be further provided at the end of the sealing member 18.

It is desirable that the dimension of the sealing member 18 in the front-rear direction is approximately 1/10 to 1/5 of the width (dimension in the front-rear direction) of the panel body 14.
Note that although the sliding member 19 is provided in this embodiment, the waterproof seal 6 may be composed of only the seal member 18.

The biasing means 7 is provided on the back side of the extensible panel 5, and includes a cylindrical member 20 whose one end is fixed to one structure 3 and whose other end is open, and whose one end is connected to the other cylindrical member 20. A movable cylinder 21 that is provided so as to be retractable into an opening at an end and whose other end is attached to the other panel main body 14b or the waterproof seal 6, and a coil spring that presses the movable cylinder 21 toward the other structure 4 side. and a biasing tool 22. By pressing the waterproof seal 6 directly or indirectly through the other panel main body 14b by the biasing means 7, the waterproof seal 6 is always in contact with the wall surface of the other structure 4 without any gaps, thereby preventing intrusion of rainwater, etc. To prevent. Note that as the biasing means 7, a known member such as a hydraulic cylinder or a coil spring that can be constantly pressed in one direction may be used.

When the structures 3 and 11 shake left and right due to an earthquake, the other structure 4 shakes in sync with the third structure 11, as shown in FIGS. 6 and 7, and the upper part of one structure 3 ( The floor surface) slides left and right to absorb the shaking motion caused by an earthquake.

When the structures 3 and 11 shake in different front and back directions due to an earthquake, and the other structure 4 rotates around the mounting member 12 and rolling member 13 and the clearance 2 becomes narrower, the expandable panel 5 will be moved as shown in FIG. As shown, as the extensible panel 5 is pressed against the other structure 4 against the urging force of the urging means 7, the overlapping width of the panel bodies 14a, 14b, and 14c increases, absorbing the shaking motion caused by the earthquake. .

On the other hand, when the clearance 2 becomes wider, as shown in FIG. 9, the other panel main body 14b is pressed by the urging force of the urging means 7, and the elastic panel 5 extends in the front-rear direction, and the panel main body The overlapping width of 14a, 14b, and 14c is reduced to absorb shaking motion caused by an earthquake. At this time, since at least a portion of the adjacent panel bodies 14a, 14b, and 14c are brought into substantially abutting state (joined state) by the holding means 15, there is no gap between the panel bodies 14, and the shaking movement caused by the earthquake is prevented. It can follow and absorb shaking movements.
