Description

The present invention relates to a floor joint covering device that covers joints between floors of adjacent buildings.

In recent years, in order to minimize the damage caused by an earthquake, many buildings have been constructed in which the lower part is supported by a seismic isolation device having a shock absorbing function. A relatively wide joint capable of absorbing the displacement caused by the earthquake is formed between the buildings having such a seismic isolation structure, and a floor joint cover device for covering the joint is arranged.

As such a floor joint cover device, for example, the configuration of Patent Document 1 has been proposed by the applicant of the present application. In the floor joint cover device 201, as shown in FIG. 11, a slider 205 is disposed at one end of a cover body 202 that covers the joints 83 between the floors of adjacent buildings, and the floor 85 of one of the buildings 81. A rail member 211 that slidably supports the slider 205 in the longitudinal direction of the joint 83 is arranged on the side edge of the joint 83. The rail member 211 includes an introduction edge portion 212 held on the side edge of the floor 85, a receiving edge portion 213 extending inward from the lower portion of the introduction edge portion 212, and the receiving edge portion 213. A locking edge portion 214 extending upward from the tip thereof is provided, and a retaining edge portion 215 protruding toward the introduction edge portion 212 is provided at the upper end of the locking edge portion 214. On the other hand, the slider 205 includes an extended edge portion 206 vertically hung from one end of the cover body 202, and a sliding edge portion 207 coupled to the lower end of the extended edge portion 206. In such a conventional configuration, the slider 205 is inserted from above between the introduction edge portion 212 and the locking edge portion 214 of the rail member 211, and the sliding edge portion 207 is the receiving edge portion of the rail member 211. It will be bearing in 213.

In the above-mentioned conventional floor joint cover device 201, when the floors of adjacent buildings are relative to each other in the longitudinal direction of the joint during an earthquake, the sliding action of the slider 205 supported by the rail member 211 causes the floor joint to cover the floor. One end edge of the cover body 202 slides along the side edge of the floor 85 of one structure 81 in the longitudinal direction of the joint, and can follow the relative displacement in the longitudinal direction of the joint.

Japanese Unexamined Patent Publication No. 2011-231525

By the way, in the above-mentioned conventional floor joint cover device 201, the rail member 211 is predetermined to be longer than the cover body 202 so that the slider 205 of the cover body 202 can slide in the joint longitudinal direction. It is formed by length. Therefore, under normal conditions without an earthquake, the rail member 211 does not support the sliding edge portion 207 of the slider 205 on both the left and right sides of the cover body 202, and the upper portion of the receiving edge portion 213 is opened. ing. Dust, sand, pebbles, etc. may enter the receiving edge portion 213 opened in this way. Then, when dust, sand, or the like enters, the slider 205 supported by the receiving edge portion 213 of the rail member 211 may not smoothly slide in the longitudinal direction of the joint. In particular, such a problem that dust, sand, etc. enter tends to occur easily when the floor joint cover device 201 is arranged outdoors.

The present invention proposes a floor joint cover device that can prevent the cover body from becoming difficult to slide smoothly due to the intrusion of dust, sand, and the like.

In the present invention, the supported portion provided at one end of the cover body extended to the joints between the floors of adjacent buildings is attached to the support receiving frame body provided at the side edge of one floor in the joint longitudinal direction. In a floor joint cover device in which the other end of the cover body is slidably supported by the side edge of the other floor in the joint width direction, the cover body is supported. The portion includes an insertion edge portion suspended from one end of the cover body, and the support receiving frame body has a vertical holding edge portion held by a side edge of the one floor and a lower portion of the holding edge portion. A guide groove into which the insertion edge portion of the cover body is inserted is provided between the bottom edge portion extending inward of the joint and the holding edge portion extending upward from the inner end of the bottom edge portion. It is provided with a locking edge portion to be formed and a support edge portion provided on the upper portion of the locking edge portion and supporting a portion of the cover body inside the joint from the insertion edge portion, and the support edge portion is used to support the portion. It is a floor joint cover device characterized in that the insertion edge portion of the cover body is held with a gap on the bottom edge portion in a state where the cover body is supported.

In such a configuration, the insertion edge of the cover body inserted into the guide groove of the support receiving frame body in a state where one end of the cover body is supported by the support receiving frame body provided on the side edge of one floor. Since the portion is raised from the bottom edge portion of the support receiving frame body, when an invading foreign substance such as dust or sand enters the guide groove, the invading foreign substance causes the cover body to slide in the longitudinal direction of the joint. It is possible to prevent it from becoming difficult. More specifically, since the invading foreign matter that has entered the guide groove is placed on the bottom edge portion, contact between the bottom edge portion and the insertion edge portion via the gap can be suppressed. Further, since there is a gap between the insertion edge portion and the bottom edge portion, when the insertion edge portion slides, the invading foreign matter in contact with the insertion edge portion can escape to the gap, so that the invading foreign matter can escape to the gap. This makes it difficult for the insertion edge to be hindered from moving. Even if the invading foreign matter enters the guide groove in this way, it is possible to prevent the insertion edge portion inserted into the guide groove from becoming difficult to slide in the longitudinal direction of the joint due to the invading foreign matter. Therefore, according to the configuration of the present invention, the cover body can smoothly slide in the longitudinal direction of the joint in the event of an earthquake even when a foreign substance has entered the guide groove of the support receiving frame body.

In the configuration of the present invention, it is preferable that the insertion edge portion constituting the supported portion of the cover body has a plate shape with the joint width direction as the plate thickness direction. Here, in the present invention, the insertion edge portion of the cover body slides the cover body in the joint longitudinal direction along the guide groove of the support receiving frame body when the cover body is relatively moved in the joint longitudinal direction between the floors. It has a function to move, and the load from the cover body does not act. Therefore, in the configuration provided with the plate-shaped insertion edge portion described above, the plate thickness of the insertion edge portion can be made relatively thin, and the guide groove of the support receiving frame body can be narrowed accordingly. .. By providing the guide groove with such a narrow width, it is possible to prevent the invading foreign matter from entering the guide groove, so that the cover body can be smoothly slid in the longitudinal direction of the joint. The effect can be further improved.

In the above-mentioned floor joint cover device of the present invention, a sliding receiving frame body that slidably supports the other end of the cover body in the joint width direction is provided on the side edge of the other floor. The cover body has a flat plate-shaped joint cover plate that covers the joints, and a plurality of guided rods that are projected from the lower surface of the joint cover plate at intervals in the longitudinal direction of the joints and extend in the width direction of the joints. The sliding receiving frames are arranged side by side at intervals in the longitudinal direction of the joint, and each guided rod of the cover body is slidably inserted in the width direction of the joint. A configuration is proposed in which a guide member and a floor cover plate which is disposed above the guide member and normally covers the other end of the cover body are provided.

In such a configuration, when the floors of adjacent buildings are relative to each other in the joint width direction during an earthquake, the guided rod of the cover body is the sliding receiving frame body provided on the other floor. By sliding with respect to the guide member, the cover body can move in the joint width direction and follow the relative displacement between the floors. Further, when the floors of adjacent buildings are displaced relative to each other in the joint width direction in this way, the insertion edge portion of the cover body inserted into the guide groove of the support receiving frame body provided on one floor is the insertion edge portion. The holding edge portion and the locking edge portion opposite to each other via the guide groove restrict the movement in the joint width direction, and the cover body can be moved integrally with the floor. Therefore, according to this configuration, the cover body can stably follow the relative displacement of the floors in the joint width direction.

In the above-mentioned floor joint cover device of the present invention, a configuration is proposed in which the support edge portion of the support receiving frame body supports the end portion of the guided rod provided on the cover body.

In such a configuration, since the end portion of the guided rod projecting from the lower surface of the joint cover plate is supported by the support edge portion of the support receiving frame body, the cover body is further attached to the support receiving frame body. Can be stably supported.

As described above, the floor joint cover device of the present invention is inserted into the guide groove of the support receiving frame body in a state where one end of the cover body is supported by the support receiving frame body provided on the side edge of one of the floors. Since a gap is formed between the insertion edge portion of the cover body and the bottom edge portion of the guide groove, the insertion edge portion is an invading foreign substance such as dust or sand that has entered the guide groove. It is possible to prevent the joint from becoming difficult to slide in the longitudinal direction. Therefore, according to the configuration of the present invention, even if a foreign substance invades the guide groove of the support receiving frame body, the cover body can smoothly slide in the longitudinal direction of the joint in the event of an earthquake.

It has been set. That is, the guide groove 47 is formed so that the insertion edge portion 15 of the cover body 11 can be smoothly slid in the left-right direction and the front-rear width (opening width) is made as narrow as possible. With such a configuration, it is difficult for dust, sand, and the like to enter the guide groove 47 that opens upward.

Furthermore, in the support receiving frame 41 of the present embodiment, as shown in FIGS. 8 to 10, a plurality of reinforcing edge portions 48 for reinforcing the strength and rigidity of the bearing edge portion 45 and the locking edge portion 44 are left and right. They are arranged at predetermined intervals in the direction. A plurality of discharge holes 50 that communicate the guide groove 47 and the joint 83 are formed in the locking edge portion 44 between the adjacent reinforcing edge portions 48. Here, the discharge hole 50 is formed so as to extend upward from the lower end of the locking edge portion 44, and the insertion edge portion 15 is inserted into the guide groove 47 of the cover body 11. The gap 49 directly below 15 is communicated with the joint 83 via the discharge hole 50 (see FIG. 5).

On the other hand, in the present embodiment, the retaining member 19 is provided to prevent the insertion edge portion 15 of the cover body 11 inserted into the guide groove 47 of the support receiving frame body 41 from coming out of the guide groove 47 upward. .. As shown in FIGS. 5 and 8, the retaining member 19 has a fixed edge portion fixed to the guided rod 13 of the cover body 11 and a retaining edge portion having a substantially L-shaped cross section protruding downward from the fixed edge portion. As described above, the fixed edge portion is screwed to the guided rod 13 of the cover body 11 in a state where the cover body 11 is supported by the support edge portion 45 of the support receiving frame body 41 (FIG. It is fixed and attached by (not shown).

As described above, in the cover body 11 delivered to the joint 83, the insertion edge portion 15 suspended at the rear end thereof is the support receiving frame body 41 in which the insertion edge portion 15 is arranged on the side edge of the floor 85 of the first building 81. By being inserted into the guide groove 47 and supported by the support edge portion 45 of the support receiving frame body 41, it is connected to the first building 81 so as to be relatively movable in the left-right direction. Then, in the cover body 11, each guided rod 13 is inserted into the insertion gap 35 of each guide member 31 arranged on the side edge of the floor 86 of the second building 82, and the support edge portion of the guide member 31 is inserted. By being supported by 34, it is supported by the second building 82 so as to be relatively movable in the front-rear direction.

The floor joint cover device 1 arranged in this way has a cover body 11 when the first building 81 and the second building 82 are relatively displaced in the longitudinal direction (left-right direction) of the joint 83 in the event of an earthquake. Since each guided rod 13 is restricted in position by each guide member 31, the cover body 11 is displaced in the left-right direction together with the second building 82, and the insertion edge portion 15 of the cover body 11 is the support receiving frame body 41. It slides in the left-right direction along the guide groove 47 of. As a result, it is possible to follow the relative displacement of the joint 83 in the longitudinal direction.
On the other hand, when the first building 81 and the second building 82 are relatively displaced in the width direction (front-back direction) of the joint 83 during an earthquake, the insertion edge portion 15 of the cover body 11 locks the support receiving frame body 41. Since the position is restricted by the edge portion 44, the cover body 11 is displaced in the front-rear direction together with the first building 81, and each guided rod 13 of the cover body 11 is along the insertion gap 35 of each guide member 31. It slides in the front-back direction. As a result, it is possible to follow the relative displacement of the joint 83 in the width direction. Here, each guided rod 13 of the cover body 11 and each guide member 31 of the sliding receiving frame body 21 generate a guiding action of relatively moving the cover body 11 in the front-rear direction.

In the configuration of the present embodiment described above, the support receiving frame body 41 arranged on the side edge of the floor 85 of the first building 81 inserts the insertion edge portion 15 provided at the rear end of the cover body 11. 47 and a bearing edge portion 45 for supporting the rear end of each guided rod 13 of the cover body 11, and the insertion edge portion of the cover body 11 in a state where the cover body 11 is supported by the bearing edge portion 45. 15 is arranged on the bottom edge portion 43a of the guide groove 47 via the gap 49. By connecting the rear end of the cover body 11 to the support receiving frame body 41 in this way, as described above, the cover body 11 can slide in the longitudinal direction of the joint 83 with respect to the first building 81. , It is possible to follow the relative displacement of the joint 83 in the longitudinal direction at the time of an earthquake. That is, the guide groove 47 of the support receiving frame body 4 and the insertion edge portion 15 of the cover body 11 generate a guiding action of relatively moving the cover body 11 in the left-right direction.
Then, in the present embodiment, the support receiving frame body 41 does not directly support the insertion edge portion 15 of the cover body 11 guided in the left-right direction by the guide groove 47, and the insertion edge portion 15 is guided. It is held in a state of being floated on the bottom edge portion 43a of the groove 47 through the gap 49. According to this configuration, when dust or sand or the like invades the guide groove 47 having a structure that opens upward, the invading foreign matter such as dust or sand is placed on the bottom edge portion 43a of the guide groove 47 and the gap 49 is formed. Easy to locate inside. Therefore, it is possible to prevent the insertion edge portion 15 of the cover body 11 from coming into contact with the invading foreign matter that has entered the guide groove 47. As a result, it is possible to prevent the insertion edge portion 15 in the guide groove 47 from becoming difficult to slide in the left-right direction due to the invading foreign matter. Further, by having the gap 49, when the insertion edge portion 15 of the cover body 11 slides, the invading foreign matter that has come into contact with the insertion edge portion 15 can escape to the gap 49. This also exerts the above-mentioned effect of suppressing the insertion edge portion 15 from becoming difficult to slide due to the invading foreign matter. Therefore, according to the configuration of the present embodiment, even if a foreign substance invades into the guide groove 47 of the support receiving frame body 41, the cover body 11 smoothly slides in the longitudinal direction of the joint 83 in the event of an earthquake. can.

Further, in the present embodiment, the bottom edge portion 43a of the guide groove 47 is composed of the inclined edge portion 43 that inclines downward, and the gap 49 and the joint 83 are communicated with each other at the lower end of the locking edge portion 44. A plurality of discharge holes 50 are provided. As a result, the invading foreign matter that has entered the guide groove 47 is easily discharged to the joint 83 through the discharge hole 50, so that the invading foreign matter makes it difficult for the insertion edge portion 15 in the guide groove 47 to slide. The effect of suppressing the above is improved, and the insertion edge portion 15 can slide more stably. Therefore, the above-mentioned action and effect that the cover body 11 can smoothly slide in the longitudinal direction of the joint 83 in the event of an earthquake is further improved.

Further, as described above, the configuration of this embodiment has a function of guiding the cover body 11 in the left-right direction by the insertion edge portion 15 of the cover body 11 and the guide groove 47 of the support receiving frame body 41. The insertion edge 15 does not support the load of the cover 11. Therefore, the insertion edge portion 15 does not require a proof stress that can support the load of the cover body 11, and can be set to a relatively thin plate thickness, and accordingly, the guide groove 47 can have a relatively narrow groove width. can. By narrowing the groove width of the guide groove 47 in this way, it is possible to suppress the invasion of the invading foreign matter into the guide groove 47. It is possible to further improve the above-mentioned effect of the present embodiment, that is, it is possible to prevent the vehicle from being difficult to slide in the left-right direction.
