When the shaking stops, the closing plate automatically returns to its normal position by the biasing device and stopper.

Description

Technical Field

[0001] The present invention relates to a floor joint plate and a floor joint device for closing a joint portion between bodies.

Background Art

[0002] Conventionally, as a floor joint device for closing a joint portion between floor surfaces and a floor joint plate used for such a floor joint device, for example, "a floor joint plate including a shallow dish-shaped joint plate body and a filling member filled in the joint plate body" is known, and it is also described in a number of patent applications filed by the applicant in the past (for example, Patent Document 1, etc.) However, although the floor joint plate can close the joint portion without problems, when the joint portion becomes narrow, the other end side of the floor joint plate rises upward with the portion attached by the locking pile as a fulcrum. Therefore, it is necessary to form a gap between the first joint plate support portion and one end portion of the floor joint plate so that the floor joint plate can rotate. However, there is a drawback that dust enters this gap.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In view of the above-mentioned conventional drawbacks, the present invention aims to provide a floor joint plate and a floor joint device that can block the gap between the floor surface of one body and one end portion of the floor joint plate without hindering the movement of the floor joint plate during an earthquake.

[0005] The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.

[0006] However, the drawings are for illustrative purposes only and do not limit the technical scope of the present invention. [Means for solving the problem]

[0007] To achieve the above objective, the floor joint plate installed in the joint formed between one structural frame and the other structural frame of the present invention comprises a joint plate body, a pile case provided inside one end of the joint plate body into which a locking pile is inserted, an inclined portion formed on the side surface of one end of the joint plate body, the upper side of which slopes toward the other structural frame, and a closing member provided on the inclined portion to close the gap between the floor surface of the one structural frame and one end of the joint plate body, the closing member closing the gap between the floor surface of the one structural frame and one end of the joint plate body. The device comprises a closing plate, a biasing device that constantly biases the closing plate toward one of the structural members, and a stopper that restricts the closing plate from moving beyond a predetermined distance toward the one structural member. When the joint narrows due to an earthquake and the other end of the joint plate body rises upward, the closing plate is pressed against the wall surface on the joint side of the one structural member and displaced toward the inclined portion. On the other hand, when the shaking due to the earthquake ends, the closing plate automatically returns to its normal position due to the biasing device and the stopper.

[0008] The closing plate of the floor joint plate according to claim 2 is formed in a substantially inverted L shape in vertical cross-section, and the stopper is characterized by comprising a pin-shaped member fixed to the closing plate, a locking portion provided on the pin-shaped member, and a locked portion provided on the inclined portion into which the locking portion is locked.

[0009] The floor joint plate according to claim 3 is further provided with an upward-lifting piece at the bottom of the joint plate body, so that when the joint narrows due to an earthquake, the joint plate body assumes a substantially horizontal position. Furthermore, the floor joint device for sealing the joint between one structural frame and the other structural frame of the present invention comprises a first joint plate support portion provided on the one structural frame, a second joint plate support portion provided on the other structural frame, and a floor joint plate attached with one end supported by the first joint plate support portion and the other end supported by the second joint plate support portion, wherein the floor joint plate comprises a joint plate body, a pile case provided inside one end of the joint plate body into which a locking pile is inserted, an inclined portion formed on the side surface of one end of the joint plate body with its upper side inclined toward the other structural frame, and a joint provided on the inclined portion between the floor surface of the one structural frame and one end of the joint plate body The system consists of a closing member that seals the gap between the two, and the closing member comprises a closing plate that seals the gap between the floor surface of one of the structural members and one end of the joint plate body, a biasing device that constantly biases the closing plate toward the one structural member, and a stopper that restricts the closing plate from moving beyond a predetermined distance toward the one structural member. When the joint narrows due to an earthquake and the other end of the joint plate body rises upward, the closing plate is pressed against the wall surface of the one structural member on the joint side and displaced toward the inclined portion. On the other hand, when the shaking due to the earthquake ends, the closing plate automatically returns to its normal position due to the biasing device and the stopper.

[0010] The closing plate of the floor joint device according to claim 5 is formed in a substantially inverted L shape in vertical cross-section, and the stopper is characterized in that it is composed of a pin-shaped member fixed to the closing plate, a locking portion provided on the pin-shaped member, and a locked portion provided on the inclined portion into which the locking portion is locked.

[0011] The floor joint device according to claim 6 is further provided with an upward-lifting piece at the bottom of the joint plate body, so that when the joint narrows due to an earthquake, the joint plate body assumes a substantially horizontal position, and the locking pile is characterized by comprising a locking pile hole formed in the horizontal surface of the first joint plate support, a long locking pile body with its lower end inserted into the locking pile hole, and a biasing spring that constantly biases the locking pile body upward. [Effects of the Invention]

[0012] As is clear from the above explanation, the present invention provides the following effects. (1) In each of the inventions described in claims 1 to 6, an inclined portion is formed on the side surface of one end of the joint plate body, and a closing member is provided to close the gap between the floor surface of one of the structures and the one end of the joint plate body. This prevents the other end of the floor joint plate from rising up during an earthquake, and minimizes the amount of debris that can enter the gap between the floor surface of one of the structures and the mounting base end (one end) of the floor joint plate. (2) Since a biasing device is provided to constantly bias the closing plate toward one side of the building structure and a stopper is provided to restrict the movement of the closing plate, when the shaking caused by the earthquake stops, the closing plate can be automatically positioned in the predetermined location and the gap between it and one side of the building structure can be reliably sealed.

Mode for Carrying Out the Invention

[0014] Hereinafter, the present invention will be described in detail according to the mode for carrying out the present invention shown in the drawings.

[0015] In the first mode for carrying out the present invention shown in FIGS. 1 to 9, reference numeral 1 denotes a floor joint device installed between one building body 3 and the other building body 4 provided via a joint part 2.

[0016] Note that the left-right direction is the left-right direction in FIG. 1 (plan view) (the longitudinal direction of the floor joint plate), the front-back direction is the up-down direction in FIG. 1 (the width direction of the floor joint plate, the direction orthogonal to the longitudinal direction), and the up-down direction is the up-down direction in FIG. 2 (the thickness direction of the floor joint plate).

[0017] In the present invention, the building body refers to a structure on which a floor joint plate such as a building, a road, a slab, an elevator shaft, etc. can be installed, and the entrance refers not only to an entrance provided with a door or a gate but also includes a passage through which people, vehicles, etc. can pass.

[0018] As shown in Figures 1 and 2, the floor joint device 1 of this embodiment consists of a first joint plate support portion 5 provided on one structural frame 3, a second joint plate support portion 6 provided on the other structural frame 4, and a floor joint plate 7 of the present invention which is attached by a locking pile 9 with one end supported by the first joint plate support portion 5, and the other end supported by the second joint plate support portion 6, and closes the joint portion 2.

[0019] One of the structural members 3 has a first joint plate support portion 5 formed thereon. In this embodiment, as shown in Figure 2, for example, this first joint plate support portion 5 is a recessed portion formed on the floor surface on the joint portion 2 side of one of the structural members 3 so as to extend in the front-rear direction, and is provided with locking piles 9 that are inserted into pile cases 8 provided at both the front and rear ends of one end of the floor joint plate 7, which will be described later. Alternatively, a metal member such as a roughly angle-shaped or roughly crank-shaped member may be fixed to the wall surface on the joint portion 2 side of one of the structural members 3 and used as the first joint plate support portion 5.

[0020] In this embodiment, the locking pile 9 consists of a locking pile hole 10 formed in the horizontal surface of the first joint plate support portion 5, a long locking pile body 28 with its lower end inserted into the locking pile hole 10, and a biasing spring 11 that constantly biases the locking pile body 28 upward. The biasing spring 11 is designed so that the locking pile 9 does not fall out of the locking pile hole 10 even when it is at its natural length. Alternatively, the upper end of the locking pile 9 may be locked inside the pile case 8 without using such a biasing spring 11.

[0021] The other structural frame 4 has a second joint plate support portion 6 formed thereon, which is made to a length that allows the floor joint plate 7 to slide left and right during an earthquake. Furthermore, at the end of the second joint plate support portion 6 opposite to the joint portion 2, there is a ramp surface 12 that the other end of the floor joint plate 7 will ride onto when the joint portion 2 narrows due to an earthquake.

[0022] The floor joint plate 7 of the present invention used in this floor joint device 1 is normally arranged such that, as shown in Figures 1 and 2, one end is supported in the mounting base end (hereinafter referred to as "one end") by inserting a locking pile 9 provided on the first joint plate support part 5 into the pile case 8 formed on the mounting base end (here referred to as "one end"), and the other end is directly or indirectly supported (via a support plate, etc.) by the second joint plate support part 6, with multiple plates provided in the front-rear direction of the joint 2 with virtually no gaps between them. In Figure 1, four floor joint plates 7 are arranged, but the number is not limited.

[0023] In this embodiment, as shown in Figures 3 to 5, the floor joint plate 7 comprises, for example, a shallow dish-shaped joint plate body 13, a filling member 14 such as mortar or concrete that is completely filled inside the joint plate body 13, a decorative panel 15 such as marble tiles or bricks provided (for example, attached) on the upper surface of the filling member 14, a pile case 8 provided at both ends in the front-rear direction on one end side of the joint plate body 13 into which the locking pile 9 is inserted, and the one end side of the joint plate body 13 It consists of an inclined portion 16 formed on the side of the joint plate body 13, the upper side of which slopes toward the other structural body, a closing member 17 provided on the inclined portion 16 that closes the gap between the floor surface of the one structural body 3 and one end of the joint plate body 13, a cover plate 19 attached to the other end of the joint plate body 13 via a hinge member 18, and a "lifting piece 27" provided at the bottom of the joint plate body 13 that causes the joint plate body to assume a nearly horizontal position when the joint portion 2 narrows due to an earthquake. The decorative panel 15 does not need to be installed in relation to the object of the present invention. The decorative panel 15 includes tiles, stone materials, and other plate-like members.

[0024] Here, "sealing the gap between the floor surface of one of the structural members 3 and one end of the joint plate body 13" includes not only a state in which the gap is completely sealed, but also a state in which there is a slight gap that prevents dirt and other debris from entering.

[0025] As shown in Figure 6, the inclined portion 16 is formed on the entire side surface of one end of the joint plate body 13, with its upper side inclined toward the other side toward the building structure (the angle between the bottom surface of the joint plate body 13 and this inclined surface is acute), and the surface of this inclined portion 16 is provided with biasing device insertion holes 23 and locking portions 26, which will be described later.

[0026] As shown in Figures 3 to 5, the closing member 17 is provided on one end side of the joint plate body 13 and consists of a closing plate 20 that closes the gap between the floor surface of the one structural frame 3 and the one end side of the joint plate body 13, a biasing device 21 that constantly biases the closing plate 20 toward the one structural frame 3, and a stopper 22 that restricts the closing plate from moving more than a predetermined distance toward the one structural frame.

[0027] The closing plate 20 can be any shape or configuration as long as it can close the gap between the floor surface of one of the structures and one end of the joint plate body, and when the other end of the joint plate body 13 rises upward, it is displaced toward the inclined portion 16 and does not obstruct the upward movement of the joint plate body 13. However, in this embodiment, a thin plate is bent to form a roughly inverted L-shape in the longitudinal cross-section.

[0028] In this embodiment, the joint plate body 13 is provided with a "lifting piece 27" at its bottom so that the joint plate body 13 is in a nearly horizontal position when the joint 2 narrows due to an earthquake. However, while the joint 2 is narrowing to a certain extent and the bottom of the lifting piece 27 is directed to the second joint plate support 6, the other end of the joint plate body 13 rises upward. Therefore, the aforementioned closing member 17 is provided to prevent obstruction of this movement.

[0029] In this embodiment, the biasing device 21 is a coil spring, with one end inserted into the biasing device insertion hole 23 formed in the inclined portion 16. Alternatively, the biasing device 21 may be fixed in the biasing device insertion hole 23. In this embodiment, the stopper 22 consists of a pin-shaped member 24 fixed to the closing plate 20, a locking portion 25 provided on the pin-shaped member 24, and a locked portion 26 provided on the inclined portion 16 into which the locking portion 25 is locked. In this embodiment, a countersunk screw 24 is used as the pin-shaped member 24, and the head of this countersunk screw 24 is fixed to the closing plate 20. A nut 25 that screws onto this countersunk screw 24 is used as the locking portion 25. The locked portion 26 is provided on the inclined portion 16 of the joint plate body 13. In this embodiment, a plate-shaped locked portion 26 is fixed to the inclined portion 16, having a through hole 26a through which the threaded portion (shaft portion) of the countersunk screw 24 can pass, but through which the nut 25 cannot pass. Furthermore, inside the locking portion 26 (on the other end side of the joint plate body 13), a movable hole 29 is formed in the inclined portion 16, allowing the shaft portion and locking portion 25 of the pin-shaped member 24 to move in the left-right direction, and the locking portion 26 is provided so as to close this movable hole 29. In this embodiment, the closing plate 20 is connected to one end of the joint plate body 13 via the stopper 22. However, the closing plate 20 may also be provided by rotatably connecting its lower end to one end of the joint plate body 13 via a hinge or the like.

[0030] When the structural members 3 and 4 sway from side to side during an earthquake, causing the joint 2 to narrow slightly, the floor joint plate 7 rides up onto the inclined surface 12 of the second joint plate support 6, as shown in Figure 7, causing the entire floor joint plate 7 to become tilted. In this state, the closing plate 20 is pressed against the wall surface on the joint side of one of the structural members 3 (the vertical wall surface of the first joint plate support 5) and displaced toward the inclined portion 16. At this time, the locking portion 25 of the stopper 22 moves through the movement hole 29 toward the other structural member 4, and the biasing device 21 becomes retracted. As the joint 2 narrows further, as shown in Figure 8, the lifting piece 27 lifts the joint plate body 13, causing the joint plate body 13 of the floor joint plate 7 to become nearly horizontal, absorbing the shaking caused by the earthquake. When the shaking caused by the earthquake stops, the closing plate 20 automatically returns to its normal position by the biasing device 21 and the stopper 22. In this embodiment, a long, pin-shaped locking pile 9 is used and is constantly biased upward by a biasing spring 11. Therefore, even if the joint plate body 13 rises upward to become approximately horizontal, the locking pile 9 can absorb the shaking caused by an earthquake without falling out of the pile case 8 of the joint plate body 13.

[0031] When the structural members 3 and 4 sway from side to side during an earthquake, causing the joint 2 to widen, the floor joint plate 7 slides from side to side on the second joint plate support 6, as shown in Figure 9, absorbing the shaking caused by the earthquake.

[0032] [Different forms for carrying out the invention] Next, different embodiments for carrying out the present invention shown in Figures 10 to 13 will be described. In describing these different embodiments for carrying out the present invention, the same reference numerals are used for components identical to those in the first embodiment for carrying out the present invention, and redundant descriptions are omitted.

[0033] In the second embodiment for carrying out the present invention shown in Figures 10 to 13, the main difference from the first embodiment for carrying out the present invention is that the floor joint plate 7A uses a joint plate body 13A without an upward-lifting piece 27, and the floor joint device 1A uses this floor joint plate and a locking pile 9A fixedly provided on the first joint plate support part 5. Even with such a floor joint plate 7A and floor joint device 1A, the same effects and advantages as in the first embodiment for carrying out the present invention can be obtained.
