Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure for waterproofing between an opening provided in a building and an outer upper surface of a connecting corridor connected to the opening. Related to the device. 2. Description of the Related Art A corridor connecting buildings is formed, for example, in the shape of a rectangular tube, and a building is formed such that both ends thereof are fitted into openings provided in an outer wall portion of the building. Connected. In order to prevent rain falling on the outer upper surface of the corridor connected to the building in this way from entering the interior of the building from the gap between the crossing corridor and the opening of the building, a conventional method has been adopted. In this case, as shown in FIG. 6, the caulking material 3 is packed in a slight gap existing between the opening 1 and the crossing corridor 2. [0003] However, when a building shakes due to an earthquake or the like, the building connected by the crossing corridor behaves differently. And moves relatively in the lateral direction, or moves in the front-back direction relative to the opening of the building. In this case, the sealability of the caulking material packed between the outer upper surface of the crossing corridor and the opening is broken, and rainwater flows along the outer upper surface of the crossing corridor and enters the interior of the building. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to move a crossing corridor in a lateral direction relative to a building or to move in and out relative to an opening of a building. Even if it moves in the forward and backward direction, it absorbs the movement and maintains the seal between the outer upper surface of the crossing corridor and the inner surface of the opening, and rainwater flows along the outer upper surface of the crossing corridor and rainwater It is an object of the present invention to provide a waterproofing device for a connecting part of a crossing corridor in a building that can prevent intrusion into the inside. [0005] A waterproofing device for a connecting part of a crossing corridor in a building according to the present invention comprises an opening provided on an outer wall of the building and an outer upper surface of the connecting corridor connected to the opening. In the waterproofing device for waterproofing the space between the building, provided in the building side, the entrance and exit directions with respect to the opening front and rear
And a guide having an open bottom surface having a front wall and a rear wall opposed to each other in front and rear, and inside the guide, relative to the guide with the relative lateral movement between the building and the passage corridor. A movable member arranged so as to be able to move laterally in a horizontal direction, and mounted on the outer upper surface of the crossing corridor so as to be relatively movable in the front-rear direction with the relative front-rear movement between the building and the crossing corridor. And a seal member attached to the movable member and slidably in contact with the outer upper surface of the crossing corridor. In the above means, the seal between the outer upper surface of the crossing corridor and the opening is made by the guide, the movable member and the seal member. When the crossing corridor moves laterally relative to the building, the movable member moves with the crossing corridor, but since the movable member is movable in the horizontal direction with respect to the guide, the movable member moves between the guide and the movable member. There is no risk of excessive force acting between them, and there is no risk of breakage. Although the movable member cannot move in the front-rear direction with respect to the guide, the movable member is not fixed to the outer upper surface of the crossing corridor, and the seal member is in sliding contact with the outer upper surface of the crossing corridor. , Because the crossing corridor is allowed to move freely in the front-rear direction, even if the crossing corridor moves in the front-rear direction relative to the building, no excessive force acts on the movable member and the sealing member, and a good seal is obtained. Maintain sex. An embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 5, a rectangular opening 13 is provided in an outer wall 12 made of, for example, lightweight cellular concrete (ALC) plate of the building 11, and an end portion of a corridor 14 is inserted and connected in the opening 13. Have been. The opening 13 is formed in a rectangular corridor 14.
It is formed to be larger than the building 11 and is movably supported by the supporting device (not shown) provided on the building 11 side in a lateral direction and a front-rear direction with respect to the building 11 (into and out of the opening 13). And, among the relatively large gaps between the opening 13 and the crossing corridor 14, the lower gap of the crossing corridor 14 is closed by a metal plate 15 made of, for example, aluminum or the like fixed to the building 11 side. The gap is closed by, for example, two metal plates 16 fixed to the building 11 side. On the other hand, the clearances on the left and right sides of the crossing corridor 14 are as follows:
It is closed by a laterally extendable closing plate device 17 called expansion metal. This closing plate device 1
Reference numeral 7 denotes a support member 18 formed of a square pipe mounted on the left and right side surfaces of the crossing corridor 14 and a support member 1 mounted on the inner surface of the opening 13 as shown in FIGS.
9 and 20; first and second rotating bodies 21 and 22 rotatably supported by the support members 19 and 20 in the front-rear direction; and first to fourth links 23 to 26 are connected to pins 27 to 30. And the first and fourth links 23 and 26
Are attached to the first and second rotating bodies 21 and 22 with the pins 31 and
And a parallel four-joint link mechanism 32 that is rotatably connected in the up-down direction via a link 31. Although a plurality of parallel four-bar linkages 33 are provided, only one is shown in FIG. The first and second rotating bodies 21 and 22 have first and second closing plates 33 and 34 attached thereto, and the second and third links 24 and 24 of the link mechanism 29, respectively.
A third closing plate 35 whose left and right sides are superimposed on the first and second closing plates 33 and 34 is attached to the pin 28 connecting the 25 through a fixture 36. Also, on the back side of these first to third closing plates 33 to 35, both ends are the first and third closing plates.
A flexible sealing band 37 attached to the second rotating bodies 21 and 22 is provided. The pins 28, 31,
31 is set to be located on a straight line. In the closure plate device 17 configured as described above, when the cross corridor 14 moves in the horizontal direction with respect to the building 11, the parallel four-joint link mechanism 32 expands and contracts in the horizontal direction to move the cross corridor 14 in the horizontal direction. Absorb. At this time, the first closing plate 33 moves in the lateral direction integrally with the crossing corridor 14, but the third closing plate 33 moves in the third direction.
Of the first closing plate 33 is moved in the same direction by the action of the parallel four-link mechanism 32, so that the first to third closing plates 33 to 35 It expands and contracts in the horizontal direction while maintaining the overlapping state. Further, when the crossing corridor 14 moves in the front-rear direction (in and out directions with respect to the opening 13), the first and second rotating bodies 2 are moved.
1 and 22 rotate to absorb the movement in the front-rear direction of the corridor 14. Therefore, there is no possibility that the closing plate device 17 will be damaged due to excessive force acting on the closing plate device 17 due to the lateral and longitudinal movement of the crossing corridor 14. As shown in FIGS. 1 and 2, a plurality of arm members 39 (FIG. 1) are provided on the frame 38 of the building 11 located on the back side of the metal plate 16 which closes the gap above the crossing corridor 14. (Only one is shown in FIG. 2) is fixed at predetermined intervals in the lateral direction by welding or the like. Guides 40 are attached to these arm members 39. The guide 40 is formed by combining a front plate portion 40a serving as a front wall and a rear plate portion 40b serving as a rear wall, and has a hollow shape having an open bottom surface. The lower end of the lower metal plate 16 of the two metal plates 16 closing the upper gap of the crossing corridor 14 is the front plate 4 of the guide 40.
0a is screwed to the lower end. The length of the guide 40 is set to be the same as the width of the opening 13.
Reference numeral 0 denotes a state where the opening 13 is disposed between the left and right inner side surfaces of the opening 13. And on the left and right sides of this guide 40,
The column 18 of the closing plate device 17, the first to third closing plates 3
The upper end portions of 3-35 are inserted. The movable member 4 is provided inside the guide 40.
1 is arranged so as to be movable in the lateral direction. The length dimension of the movable member 41 is set to be the same as the interval between the pair of columns 18 attached to the left and right sides of the crossing corridor 14. Therefore, the movable member 41 is disposed between the pair of columns 18. When the corridor 14 moves laterally relative to the building 11, the corridor 14 moves in the guide 40 and integrally with the corridor 14. The movable member 41 is formed in a substantially inverted convex shape by a metal plate material. The movable member 41 is rotatably supported by a longitudinal axis 42 on both front and rear sides of an upper portion.
An upper roller 43 made of, for example, plastic and coming into contact with Ob is provided intermittently. In addition, a lower roller 45 made of, for example, plastic is provided below the movable member 41 and rotatably supported by the horizontal shaft 44 and is in contact with the outer upper surface of the crossing corridor 14. The movable member 41 includes the lower roller 45. It is placed on the outer upper surface of the corridor 14 via the bridge. Band-shaped sealing members 46 and 47 made of, for example, neopress rubber are attached to the front and rear sides of the lower portion of the movable member 41.
The lower halves of 6, 47 are in sliding contact with the outer upper surface of the passage corridor 14 while being elastically deformed in a substantially L-shape. Next, the operation of the above configuration will be described. First, on a rainy day, rainwater that has fallen on the outer upper surface of the crossing corridor 14 flows along the outer upper surface of the crossing corridor 14 and flows inward in the building 11. However, on the outer top of the corridor 14,
Since the sealing members 46 and 47 attached to the movable member 41 are in sliding contact with each other, the sealing action prevents rainwater from entering the building 11 along the outer upper surface of the crossing corridor 14. Further, even if rainwater enters with a wind from a slight gap between the outer upper surface of the corridor 14 and the metal plate 16, the guide 40 and the movable member 41 on the rear side function as barriers, so that the 11 does not penetrate. Now, when an earthquake or the like occurs, the corridor 14
Moves in the lateral direction or the front-back direction with respect to the building 11. When the crossing corridor 14 moves in the horizontal direction, the closing plate devices 17 on the left and right sides expand and contract, and the movable member 41 moves in the horizontal direction in the guide 40, thereby allowing the crossing corridor 14 to move in the horizontal direction. At this time, the movable member 41 is moved by the upper roller 4 in contact with the front and rear plate portions 40a and 40b of the guide 40.
3 is performed smoothly by rotation. When the crossing corridor 14 moves in the front-rear direction, the closing plate devices 17 on the left and right sides rotate with a slight extension, allowing the crossing corridor 14 to move in the front-rear direction. At this time, the movable member 41 in the guide 40 is in a state in which the movement in the front-rear direction is restricted, but only the rotatable lower roller 45 receives the outer upper surface of the crossing corridor 14, In addition, the sealing members 46 and 47 are also simply provided in the corridor 1.
4 is only in sliding contact with the outer upper surface,
4 freely moves back and forth while rotating the lower roller 45. Even if the crossing corridor 14 moves in the lateral direction and the front-rear direction with respect to the building 11, the guide 40, the movable member 41, and the seal members 46 and 47 are not likely to be damaged by the movement, so that the corridor 14 can be used for a long time. It is possible to prevent rainwater from flowing along the outer upper surface of the passageway 14. In the above embodiment, the movable member 41 is brought into contact with the guide 40 and the passageway 14 via the upper roller 43 and the lower roller 45. However, depending on the degree of friction, the movable member 41 and the guide 40, The crossing corridor 14 may be directly contacted, and may be provided as needed. In the above-described embodiment, the seal members 46 and 47 are provided on both front and rear sides of the movable member 41. However, only one of them may be provided. In addition, the present invention is not limited to the embodiment described above and shown in the drawings. For example, the extendable closing plate device 17 may be replaced with another known device, and various modifications may be made without departing from the scope of the invention. It can be implemented. As described above, according to the present invention, the crossing corridor moves in the lateral direction relative to the building,
Even when the building moves in the front-rear direction relative to the opening of the building, it can absorb the movement and maintain the sealing property between the upper surface of the crossing corridor and the inner surface of the opening for a long period of time. This has an excellent effect that rainwater can be prevented from entering the inside of the building along the outer upper surface of the building.
