DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tubular structure called, for example, a communication bridge which is bridged between two structural buildings, and an opening of the building into which one end in the longitudinal direction of the tubular structure is inserted. The present invention relates to a telescopic seal device and a method of mounting the telescopic seal device, which closes a gap generated between the inner peripheral portion of the building and a cylindrical structure in an acceptable manner.

[0002]

2. Description of the Related Art For example, two high-rise buildings such as a main building and an annex of a hotel are provided adjacent to each other, and a tubular structure called a connecting bridge is bridged between the buildings in order to connect these buildings to each other. In addition, building facilities that allow customers to freely move from one building to another building by using this tubular structure are frequently used.

Each building has an opening into which one end in the longitudinal direction of the tubular structure is inserted, and in this opening, one end of the tubular structure can be angularly displaced around an axis perpendicular to each building. When each building is relatively displaced due to a sudden earthquake and uneven settlement of the ground, the displacement is allowed. Therefore, a gap is formed between the inner periphery of each building surrounding the opening and the outer peripheral surface of each end of the tubular structure, and in order to prevent rainwater or the like from entering the gap, An expansion joint device is interposed.

[0004] This expansion joint device extends between the rims fixed to each building and the tubular structure, and each rim, and allows relative displacement of each rim by the respective rim. A flat cover plate to be supported, a spring for resiliently pulling the cover plate from the gap side, and a space between the tubular structure and the building, which is further in the gap side than the spring. Extending, a sheet-shaped water-stop board having flexibility such as rubber, and a fire-resistant zone that is provided further inward on the gap side than the water-stop board and extends between the tubular structure and the building, The cover body blocks the wind and rain sprayed into each gap, the cover body blocks the water that could not be blocked by the water stop plate, and the fire and hot air at the time of fire can be blocked by the fireproof zone. Have been .

[0005]

In such a conventional technique, a rim is attached to a tubular structure and a building, respectively.
In addition, since the water stop plate and the refractory must be accommodated in the gap, the mounting work of the expansion joint device is complicated, and the configuration of the expansion joint device is complicated.

Accordingly, an object of the present invention is to allow a relative displacement between a tubular structure and a frame with a simple structure, and to reliably prevent the invasion of wind and rain from the outside into the gap. Another object of the present invention is to provide a telescopic seal device that can simplify the mounting operation, and a mounting method thereof.

[0007]

According to the present invention, there is provided a cylindrical structure, and a frame having an opening in which one end in the longitudinal direction of the cylindrical structure is inserted with a gap from an outer surface of the cylindrical structure. A plurality of covers are provided on an inner peripheral portion surrounding the opening of the frame, facing the one end of the tubular structure inserted into the opening, and each cover body has a cylindrical structure. A seal member slidably in contact with the outer surface of one end of the cylindrical member is provided on the back side of at least the left and right sides of the plurality of cover members. A spring means for resiliently biasing the outer surface of one end of the seal device.

Further, according to the present invention, the outer surface of one end of the tubular structure is parallel to the longitudinal axis of the tubular structure and is located outside the outer surface of the intermediate portion in the longitudinal direction of the tubular structure. It is characterized by being formed to protrude in the direction.

Further, according to the present invention, a cover body to which a sealing material is attached is held by a holding body, and a spring is disposed between the cover body and the holding body to urge the cover body in a direction to protrude from the holding body. The first assembly and the second assembly in which the cover body to which the sealing material is attached are held by the holding body are assembled in a state where one end of the tubular structure is inserted into the opening of the body. A first assembly is mounted on left and right sides of an inner peripheral portion of the opening, and a second assembly is mounted on upper and lower sides of the inner peripheral portion.

[0010]

According to the present invention, an opening is formed in the body to insert one end in the longitudinal direction of the tubular structure, and a plurality of covers are provided on an inner peripheral portion surrounding the opening of the body. Provided. Sealing members are provided on each cover body, and these sealing members slidably contact the outer surface of one end of the tubular structure. Rain water from the outside can be blocked by such a sealing material. Further, a spring means is provided on at least the back side of the cover bodies arranged on both left and right sides of the plurality of cover bodies, that is, on the side opposite to the side on which the sealing material is provided. By this spring means, the cover bodies arranged at least on the left and right sides are resiliently urged toward the outer surface of one end of the tubular structure together with the seal members provided on the cover bodies, whereby The material resiliently contacts the outer surface. With such a configuration, even when a sudden earthquake and uneven settlement of the ground cause relative displacement with respect to the tubular structure, the sealing material provided on the cover body disposed on the left and right sides is replaced with the tubular structure. It is possible to maintain a state in which the body is always elastically brought into contact with the outer surface of the body, and a decrease in watertightness is prevented. In addition, since the telescopic seal device of the present invention includes the cover body, the seal member, and the spring means, the number of parts is small, the configuration is simplified, and the mounting operation is easy.

According to the invention, the outer surface of one end of the tubular structure is parallel to the longitudinal axis of the tubular structure. Thereby, even if the cylindrical structure and the frame body are relatively displaced in the longitudinal direction, the cover body and the seal material are less likely to separate from or be displaced from the outer surface in the direction in which the cover member and the seal material are always displaced. Can be kept in contact with the outer surface of the tubular structure. The outer surface is formed so as to protrude outward from an outer surface of an intermediate portion of the tubular structure. Therefore, when the cylindrical structure is relatively displaced in the longitudinal direction, like the outer surface of the one end, the sealing material is smoothly slid on all the outer surfaces in the longitudinal direction of the cylindrical structure. In consideration of this, it is not necessary to be highly accurate and parallel to the longitudinal axis, and the gap between the inner peripheral portion of the skeleton and the outer surface of the tubular structure is reduced, thereby reducing the gap to the gap. Invasion of wind and rain can be reduced. Also, since the gap is small, the amount of protrusion of the sealing material from the cover body can be reduced, so that it is not necessary to use a large sealing material, and the sealing material can be downsized.

Further, according to the present invention, the cover to which the sealing material is attached is held by the holder, and a spring for urging the cover in a direction protruding from the holder is interposed between the cover and the holder. The assembled first assembly and the second assembly in which the cover body to which the sealing material is attached are held by the holding body are assembled, respectively, and one end of the tubular structure is inserted into the opening of the body. The first assembly is mounted on the left and right sides of the inner periphery of the opening, and the second assembly is mounted on the upper and lower sides of the inner periphery. In this way, the first and second assemblies can be carried to the site in a state where they have been assembled in advance, and these assemblies can be attached to the inner peripheral portion. Workability can be improved.

According to the present invention, the sealing material attached to the cover body is brought into contact with the outer surface of one end of the tubular structure inserted into the opening of the body so that the inner surface faces the outer surface. Since the gap between the peripheral surface and the peripheral surface is closed, entry of wind and rain in the gap from the outside can be prevented with a simple configuration. In addition, since the cover members arranged on at least the right and left sides of the plurality of cover members are elastically urged toward the outer surface by the spring means, the tubular structure and the frame are horizontally opposed to each other. The sealing material on the outer surface,
In particular, it can be brought into a state of being securely contacted with both side surfaces in the horizontal direction, thereby improving the water tightness.

Further, according to the present invention, since the outer surface of one end of the tubular structure is formed parallel to the longitudinal axis of the tubular structure, the tubular structure and the skeleton are joined to each other. Therefore, even if a relative displacement occurs in the axial direction, the sealing material can be brought into a state of uniformly contacting the outer surface, thereby preventing a decrease in sealing performance. Further, since the outer surface of the tubular body is formed to protrude outward from the outer surface of the intermediate portion, the amount of protrusion of the seal material can be reduced, the seal material can be reduced in size, and the configuration is simplified.
