Abstract

PROBLEM TO BE SOLVED: To provide a joint cover device for floor applicable to a corner part of a joint. SOLUTION: One end of cover bodies C1, C2 arranged in a part other than a corner part (p) of a joint (s) among a plurality of cover bodies C1, C1', C2, C2' is connected with a floor side fringe of a building A on one side so as to swing, opposing side fringes of cover bodies C1', C2' in an end part arranged in the corner part (p) of the joint (s) and cover bodies C1, C2 adjacent to the cover bodies C1', C2' are connected through a hinge, and the cover bodies C1', C2' in the end part are provided by tilting them for the adjacent cover bodies C1, C2. Consequently, a top face of a free end of each cover body C1, C1', C2, C2' to be put on a slide groove 4 has substantially the same height as a floor surface in the surroundings usually, and the cover bodies C1', C2' in the end part slide up along an inclined receive face 3 which is orthogonal for them in the corner part (p) of the joint (s) when earthquake occurs to escape from its relative displacement.

Description

DETAILED DESCRIPTION OF THE INVENTION [0001] BACKGROUND OF THE INVENTION The present invention relates to a method for constructing a building between adjacent buildings.
And a floor joint covering device for covering the joint. [0002] 2. Description of the Related Art In a floor joint cover device, particularly,
Seismic isolation with lower part supported by seismic isolation device with shock function
General floor joint covering device applied to structural buildings
Is the floor side edge of the seismically isolated building a, as shown in FIG.
And one end of a cover body c covering the joint s via a connecting means d.
And fix the other end of the cover body c as a free end e.
Place the tip e on the floor side edge of the other building b made of artificial ground
It is slidably mounted and can be moved between buildings a and b in the horizontal direction.
(Joint width direction) and front-rear direction (direction along joint)
When a displacement occurs, the free end e of the cover body c is
On the floor edge of the floor to follow the relative displacement
It is supposed to. [0003] By the way, in the joint cover device having such a configuration,
The upper surface g of the cover c and the floor i of the building b
A step h corresponding to the thickness of the cover c is generated between
The step h hinders traffic, especially in hospitals and public offices.
In buildings where there are many opportunities for elderly people and disabled people to visit
There was a disadvantage that it was not suitable for use. Therefore, as shown in FIG.
Of the building a to the floor side edge of the building a via the connecting means d.
To the free end e of the cover body c from its lower surface.
While forming an inclined edge j inclined toward the upper surface of the outer end,
The floor b of the building b is inclined in the same direction as the inclined edge j.
A sliding groove m having an inclined receiving surface k at its outer end.
m on the free end e of the cover body c.
Joint cover device in which the step h is not generated
However, Japanese Patent Application Nos. Hei 9-22108 and Hei 9-143246
No. etc. have already been proposed by the present applicant. [0005] This joint cover device is provided on the left side of buildings a and b.
At the time of relative displacement in the right direction (joint width direction),
When a and b are relatively displaced in the approaching direction, the cover body
c is along the inclined receiving surface k at the outer end of the sliding groove m.
The cover body c tilts around the connecting means d as a fulcrum.
By doing so, you can escape from the relative displacement
ing. [0006] By the way, in the above-mentioned structure,
Attempt to install joint cover device at corner of joint s
In this case, as shown in FIG.₁ And mosquito
Bar body c₂ Are arranged in an L shape along the corner, and
Cover body c₁ , C₂ Is connected to the floor perpendicular to building a.
Connecting means d on the edge₁ , D₂ Swingably connected via
And cover body c₁ , C₂ Free end e₁ ,
e₂ Sliding groove m provided on the floor side edge orthogonal to building b side
₁ , M₂ Will be on board. However, like this
In the arrangement state, for example, the cover c₁ Side building
When the structures a and b are relatively displaced in the approaching direction,
-Body c₁ Means connecting means d₁ With free end e₁
Is the sliding groove m₁ Inclined surface of k₁ Up along the
Although it is possible to escape from the relative displacement, the cover body c₂
 Has an inclined receiving surface k₁ No tilt function in the direction perpendicular to
Therefore, the cover c₂ Is inclined receiving surface k₁ Hit against and damaged
Resulting in. Also, the cover body c₂ The buildings a and b on the side
When the relative displacement occurs in the approaching direction, the same
Cover body c₁ Is damaged. For this reason, joints
The joint cover device of the conventional configuration should be applied to the
There was a problem that can not be. The present invention can solve such a conventional problem.
It is an object of the present invention to provide a floor joint cover device. [0008] SUMMARY OF THE INVENTION The present invention relates to an adjoining building
