Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a floor expansion joint device provided between opposing portions facing each other with a gap between the floors of two adjacent buildings.
[0002]
[Prior art]
In multiple buildings such as apartment buildings, hospitals, schools, and commercial multipurpose buildings, the opposing portions of each floor of two adjacent buildings close the gap between the opposing portions, and sudden earthquakes, etc. The expansion joint device for floors which can permit the relative displacement of each opposing part by is provided. This expansion joint device for floors is also called an expansion joint, an edge member fixed to each facing part, one end part is supported by one edge member, and the other end part is attached to the other edge member. And a cover body that closes the gap in a state of being connected to a horizontal axis by a hinge so as to be angularly displaceable.
[0003]
Each edge member is a long member made of an extruded shape member made of steel, stainless steel, or aluminum alloy, and is fixed to each opposing portion in parallel in a substantially horizontal direction by a plurality of anchor bolts. The one end portion of the cover body is relatively displaced in a direction in which each facing portion is brought close to a portion where the one end portion of the one edge member faces due to a sudden earthquake or uneven settlement of the ground. In order to allow the displacement, it is supported in a state of being horizontally separated from the facing portion of the one edge member.
[0004]
[Problems to be solved by the invention]
In such conventional technology, relative displacement between buildings caused by earthquakes and uneven settlement of the ground, especially relative displacement between opposing portions, is in the direction in which the opposing portions approach and separate from each other. Displacement, displacement in the direction in which each facing portion moves in the horizontal plane, and displacement in the direction in which each facing portion moves in the vertical direction are generated as a three-dimensionally synthesized displacement, but mainly in the direction in which each facing portion approaches. When the displacement is large, the cover body connected to the support body provided at one of the opposed portions is pressed against the edge material of the other opposed portion.
[0005]
As described above, since the one end of the cover body is attached in a state of being horizontally separated from the opposing portion of the other edge member, it is between the one end of the cover body and the other edge member. There is a case where there is a gap, and foreign matter such as pebbles and dust may enter the gap. If foreign matter exists in such a gap, when the opposing parts are displaced in a direction close to each other, the cover body smoothly rides on one edge member by the foreign matter and allows the displacement in the close direction. I can't. Therefore, there is a problem that a large reaction force acts on the cover body from one edge member through the foreign matter, and the cover body is damaged. Further, the width of the gap is larger on the artificial ground than the building built on the local board, and includes a displacement due to thermal expansion and contraction, which may cause a passerby to trip. There is.
[0006]
Also, since the cover body is tightened with screw members such as bolts while the cover body is supported by an operator when the cover body is attached, the cover body has a structure with a large weight and thickness such as a tile. In some cases, the mounting work requires a lot of labor and labor, and there is a problem that the workability of the cover mounting work is poor.
[0007]
The object of the present invention is to prevent foreign matter from entering the gap between the edge member and the cover body, and to prevent the cover body from being damaged by the displacement of the facing portions in the direction close to each other. An object of the present invention is to provide a floor expansion joint device that can be smoothly passed.
[0008]
Another object of the present invention is to provide a floor expansion joint device that simplifies the work of attaching the cover body and allows the cover body to be easily attached.

[Means for Solving the Problems]
The present invention as set forth in claim 1 is an edge member fixed to each facing portion facing each other with a space between each floor of two adjacent buildings.
A support that is fixed to any one of the edges and protrudes from one edge toward the other edge;
A cover body supported by each edge member and connected to the support body, and closing the gap between the support bodies;
The other edge member includes an auxiliary cover body that is rotatably provided about an axis parallel to the longitudinal direction in which the other edge member extends, and covers a gap between the other edge member and the cover body. The floor expansion joint device is characterized.
[0010]
According to the present invention, the edge material is fixed to each facing portion of each floor of two adjacent buildings. A support is fixed to either one of the edges. The support protrudes from the one edge member in a direction close to the other edge member, and the cover body is connected to the support member.
[0011]
When each building undergoes a relative displacement due to a sudden earthquake or uneven ground subsidence, etc., even if the cover body separates from the other edge material, the opposing body will be displaced in a direction that separates from each other. Since the cover body is displaced following one of the casings while being connected to the support body, the cover body is supported by the support body, and the cover body is prevented from falling into the gap, and each opposing portion is With respect to displacement in directions close to each other, the cover body is prevented from being damaged or broken by contacting the other facing portion.
[0012]
In addition, the displacement in the direction in which each facing portion moves in parallel in the horizontal plane is allowed to move in the parallel direction because the cover body and the other facing portion are not coupled. Further, in the displacement in the direction in which each facing portion moves up and down, the cover body has the other edge member and the other edge member with respect to the displacement in the direction in which the cover body and the other edge member are relatively separated in the vertical direction. Displacement can be allowed without interfering with the facing portion. Further, in the displacement in the direction in which each facing portion moves up and down, the cover body is opposed to the other edge material or the other with respect to the displacement in the direction in which the cover body and the other edge material are relatively close to each other in the vertical direction. For example, a state in which a spring is interposed between the cover body and the support body so as to allow displacement in a direction in which the cover body is relatively close to the top and bottom relative to the support body in order to interfere with the portion. A large upward force is applied to the cover body from the other edge member or the other facing portion by a known technique in which the cover body is connected to the support body in a state where the cover body can be displaced up and down by the loose bolt. Can be avoided.
[0013]
Thus, the respective displacements in the direction in which each facing portion approaches and separates from each other, the direction in which each facing portion translates in the horizontal plane, and the direction in which each facing portion moves in the vertical direction are three-dimensionally synthesized displacements. However, since the displacement in the direction in which each facing portion mainly approaches has the greatest influence on the damage or destruction of the cover body, by preventing damage or destruction of the cover body to this displacement in the proximity direction, In practice, even if the relative displacement of each facing portion occurs due to an earthquake and uneven ground subsidence, the cover body is practically prevented from being damaged or broken.
[0014]
An auxiliary cover body is provided on the other edge member. The auxiliary cover body is angularly displaceable about an axis parallel to the longitudinal direction in which the other edge member extends. Since the gap between the other facing portion and the cover body is covered by such an auxiliary cover body, foreign materials such as pebbles and dust are prevented from entering the gap, and the directions in which the facing portions are close to each other are prevented. Even if this displacement occurs, it is possible to prevent a large reaction force from acting on the cover body through the foreign material from the other edge material, preventing the cover body from being damaged or destroyed, and preventing a passerby from tripping. Can be removed.
[0015]

[0016]
According to the present invention, the edge material is fixed to each facing portion of each floor of two adjacent buildings. A support is fixed to either one of the edges. The support protrudes from the one edge member in a direction close to the other edge member, and the cover body is connected to the support member.
[0017]
When each building undergoes a relative displacement due to a sudden earthquake or uneven ground subsidence, etc., even if the cover body separates from the other edge material, the opposing body will be displaced in a direction that separates from each other. Since the cover body is displaced following one of the casings while being connected to the support body, the cover body is supported by the support body, and the cover body is prevented from falling into the gap, and each opposing portion is With respect to displacement in directions close to each other, the cover body is prevented from being damaged or broken by contacting the other facing portion.
[0018]
In addition, the displacement in the direction in which each facing portion moves in parallel in the horizontal plane is allowed to move in the parallel direction because the cover body and the other facing portion are not coupled. Further, in the displacement in the direction in which each facing portion moves up and down, the cover body has the other edge member and the other edge member with respect to the displacement in the direction in which the cover body and the other edge member are relatively separated in the vertical direction. Displacement can be allowed without interfering with the facing portion. Further, in the displacement in the direction in which each facing portion moves up and down, the cover body is opposed to the other edge material or the other with respect to the displacement in the direction in which the cover body and the other edge material are relatively close to each other in the vertical direction. For example, a state in which a spring is interposed between the cover body and the support body so as to allow displacement in a direction in which the cover body is relatively close to the top and bottom relative to the support body in order to interfere with the portion. A large upward force is applied to the cover body from the other edge member or the other facing portion by a known technique in which the cover body is connected to the support body in a state where the cover body can be displaced up and down by the loose bolt. Can be avoided.
[0019]
Thus, the respective displacements in the direction in which each facing portion approaches and separates from each other, the direction in which each facing portion translates in the horizontal plane, and the direction in which each facing portion moves in the vertical direction are three-dimensionally synthesized displacements. However, since the displacement in the direction in which each facing portion mainly approaches has the greatest influence on the damage or destruction of the cover body, by preventing damage or destruction of the cover body to this displacement in the proximity direction, In practice, even if the relative displacement of each facing portion occurs due to an earthquake and uneven ground subsidence, the cover body is practically prevented from being damaged or broken.
[0020]
The cover body is provided with an auxiliary cover body. The auxiliary cover body is angularly displaceable about an axis parallel to the longitudinal direction in which the other edge member extends. Since the gap between the other facing portion and the cover body is covered by such an auxiliary cover body, foreign materials such as pebbles and dust are prevented from entering the gap, and the directions in which the facing portions are close to each other are prevented. Even if this displacement occurs, it is possible to prevent a large reaction force from acting on the cover body through the foreign material from the other edge material, preventing the cover body from being damaged or destroyed, and preventing a passerby from tripping. Can be removed.
[0021]
According to a third aspect of the present invention, the cover body includes a frame member having a substantially concave cross section perpendicular to the longitudinal direction thereof, and a bottomed cylindrical partition member fixed to the frame member at a position where the support body is provided.

In the floor expansion joint device 1 described above, when each building undergoes a relative displacement due to a sudden earthquake or unequal subsidence of the ground, for the displacement in the direction in which the facing portions 4a and 4b are separated from each other. Even if the cover body 7a is separated from the other edge member 5a, the cover body 7a is connected to the support body 6 so that the cover body 7a is supported by the support body 6 and the cover body 7a falls into the gap 3 This prevents the cover body 7a from coming into contact with the other facing portion 4a and being damaged or destroyed by the displacement of the facing portions 4a and 4b in the direction of approaching each other.
[0040]
Also, the cover body 7a and the other facing portion 4a are coupled to each other in the direction in which the facing portions 4a and 4b move in parallel in the horizontal plane (direction perpendicular to the paper surface of FIGS. 5 and 6). Therefore, the movement in the parallel direction can be allowed. Furthermore, with respect to the displacement in the direction in which each of the facing portions 4a and 4b moves up and down (the up and down direction in FIGS. 5 and 6), the other edge member 5a moves downward with respect to the cover body 7a, or the cover If the body 7a is displaced in the direction in which the body 7a moves upward with respect to the other edge member 5a, the cover body 7a and the other edge member 5a or the other facing portion 4a do not interfere with each other and can be allowed.
[0041]
Thus, the displacement of the facing portions 4a and 4b in the direction of approaching and separating from each other, the displacement of the facing portions 4a and 4b in the direction of translation in the horizontal plane, and the direction of movement of the facing portions 4a and 4b in the vertical direction These displacements occur as three-dimensionally synthesized displacements, but mainly the displacement in the direction in which the opposing portions 4a and 4b are close to each other has the greatest influence on the damage or destruction of the cover body 7a. Therefore, by preventing damage or destruction of the cover body 7a with respect to the displacement in the adjacent direction, even if the relative displacement of each facing portion is actually caused by an earthquake or uneven subsidence of the ground, the cover is actually covered. The body 7a is prevented from being damaged or destroyed.
[0042]
An auxiliary cover body 10a is provided at the free end of the cover body 7a. The auxiliary cover body 10a is angularly displaceable about an axis 8 parallel to the longitudinal direction in which the other edge member 5a extends. Since the gap 9 between the other edge member 5a and the cover body 7a is covered by such a cover body 7a, foreign matter such as pebbles and dust can be prevented from entering the gap 9, and each facing portion 4a, Even if the displacement in the direction in which the 4b is close to each other occurs, it is possible to prevent a large reaction force from acting on the cover body 7a from the other edge member 5a through foreign matter, and to prevent damage or destruction of the cover body 7a. In addition, it is possible to prevent the passerby from tripping and to enable smooth passage.
