Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting passage provided, for example, between high-rise buildings or between marine structures, so that a large relative displacement between structures due to an earthquake, wind, waves, etc. can be dealt with. It was done.

[0002]

2. Description of the Related Art Conventionally, a connecting passage used to connect low-rise buildings has a small displacement between buildings, and therefore the bearing has a horizontal rotation function and a horizontal movement function. In addition, the walk floor in the connecting passage is separated from the walk floor on the building side at both ends of the connecting passage, and expansion joints are provided at that portion.

[0003]

By the way, in a high-rise building, by providing a communication passage in the high-rise part, the traveling time between the high-rise buildings can be significantly shortened, and the work efficiency and the congestion of the elevator can be eliminated. . There is also an advantage that one building can be evacuated to the other in case of a fire or other emergency.

However, in the high-rise connecting passage, the relative displacement between the high-rise buildings due to an earthquake or wind becomes large, and the horizontal passage in the direction perpendicular to the passage and the horizontal displacement in the passage direction, which are the study conditions in the low-rise connecting passage, are considered. In addition, it is necessary to consider vertical displacement, relative twist between buildings, and floating of the communication passage due to strong wind blowing.Therefore, the conventional horizontal rotation function and horizontal movement function of the low-rise communication passage alone are not enough. I can't cope.

Further, the walking floor installed inside the structure of the communication passage also has a large displacement, so that it is difficult to deal with the conventional expansion joints at both ends of the passage only when considering safe walking. .

Further, for example, in the case of a passage connecting between offshore structures or between an offshore structure and a quay, a structure that is easily affected by wind and waves and can cope with a large displacement is desired.

The present invention aims to solve the above problems.

[0008]

The outline of the present invention will be described below with reference to the reference numerals in the drawings corresponding to the embodiments.

In the present invention, the structure 1 that constitutes the communication passage 1
a and the walking floor 21 installed inside the structure 1a are structurally separated, and the walking floor 21 is divided in the passage direction to form a plurality of divided floor portions (22). Further, each divided floor portion (22) is supported so as to be slidable in the horizontal direction with respect to the structure 1a.

By structurally separating the walking floor 21 from the structure 1a, the walking floor can be displaced independently of the structure 1a with respect to the relative displacement between the structures a and b, and in the passage direction. The division makes it possible to disperse the displacements and reduce the individual displacements at the division positions.

A support mechanism for the divided floor portion (22) is a roller, a caster, or a wheel 2 traveling on a rail.
6 mag is considered.

Further, the pantograph 23 is provided between the divided floor portions (22) so as not to hinder walking on the walking floor 21.
It is preferable that the split floors (22) are evenly distributed by connecting them with an expansion device, etc., and the adjacent split floors (22) are connected by an expansion joint 24 or the like.

Embodiments Next, the illustrated embodiments will be described.

FIGS. 1 to 3 show an embodiment in which the communication passage of the present invention is applied to a passage between high-rise buildings a and b as shown in FIG.

Structure 1a constituting the main body of the communication passage 1
As shown in FIG. 2, one end is supported by the high-rise building a by the pin bearing 2 and the other end is supported by the high-rise building b by the roller bearing 3.
Supported by. With respect to the relative displacement between the high-rise buildings a and b, the structure 1a is displaced in a substantially rigid state, and the bearing portion is configured to handle the relative displacement.

In the high-rise connecting passage 1, a large relative displacement occurs between the high-rise buildings a and b, so that the walking floor 21
A large displacement also occurs in a part, and in order to cope with this, the walking floor 21 is structurally separated from the structure 1a and is divided into a plurality of parts in the passage direction to form a divided floor part.
Is slidable in the horizontal direction (passage direction) with respect to the structure 1a.

In the example of FIG. 3, the rail 4 is provided on the floor of the structure 1a.
And the wheels 26 provided on the lower surface of each floor panel 22 travel along the rails 4. In addition, as the sliding mechanism, a structure in which a roller or a caster is provided on the lower surface of the floor panel 22 so as to directly slide on the floor portion of the structure 1a may be used.

As shown in FIGS. 1 to 3, a pantograph 23 as a telescopic device is provided on the lower surface of the floor panel 22, and the floor panels 22 are connected to each other. , B.

With the above structure, the pantograph 23 expands and contracts with respect to the relative displacement of the buildings a and b due to an earthquake or wind.
Separately from the displacement of the structure 1a, the displacement between the buildings a and b can be evenly distributed between the floor panels 22.

The expansion / contraction device is not limited to the pantograph type as long as it can evenly or almost evenly disperse the displacement between the high-rise buildings a and b between the floor panels 22. Further, instead of providing a telescopic device, a drive device is provided on each floor panel 22, and relative displacement is determined by a sensor,
A type in which the floor panel 22 is moved by electrically controlling the drive device is also conceivable.

FIG. 5 shows a case where the lower surface of the floor panel 22 is roller-supported (not shown) as another embodiment. In order to stabilize the movement of each floor panel 22 constituting the walking floor 21, a guide is provided on the side surface. A roller 25 is provided.

Although not shown in FIGS. 1 to 3, an expansion joint 24 composed of, for example, a comb-like arm as shown in FIG. 5 is provided between the floor panels 22 to eliminate steps on the walking floor. . In addition, the structure of the expansion joint between the floor panels 22 is not limited to the above, and various types conventionally used for the walking floor end or the like can be applied.

[0023]

EFFECTS OF THE INVENTION The amount of displacement conventionally concentrated at the walking floor end portion of the communication passage can be dispersed according to the number of divisions of the walking floor portion.

Therefore, even in a passage that causes a large displacement, such as a passage between high-rise buildings or between marine structures, the amount of displacement in each part of the divided walking floor is suppressed to a degree that does not hinder walking. You can

By forming the communication passage of the high-rise part, the traveling time between the high-rise buildings can be significantly shortened, and the efficiency of the work and the congestion of the elevator can be eliminated. In addition, there is an advantage that one building can be evacuated to the other in case of a fire or other emergency.
