Embodiments for Carrying Out the Invention

[0016] Hereinafter, the present invention will be described in detail according to the embodiments for carrying out the present invention shown in the drawings.

[0017] In the first embodiment for carrying out the present invention shown in FIGS. 1 to 12, reference numeral 1 denotes a floor joint device installed between one housing 3 and the other housing 4 provided via a joint part 2.

[0018] 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-rear 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).

[0019] In the present invention, the structure refers to a building such as a building, a road, a slab, an elevator shaft, etc. where a joint plate can be installed. The entrance does not only refer to an entrance with a door or a gate, but also includes a passage through which people, vehicles, etc. can pass.

[0020] As shown in FIGS. 1 to 3, the floor joint device 1 of the present embodiment includes a first joint plate support portion 5 provided on one structure 3, a second joint plate support portion 6 formed on the other structure 4, and one end portion side is supported by the first joint plate support portion 5. It is attached in a supported state, the other end portion side is supported by the second joint plate support portion 6, and it is composed of the floor joint plate 7 of the present invention that closes the joint portion 2.

[0021] A first joint plate support portion 5 is formed on one structure 3. This first joint plate support portion 5 is, for example, as shown in FIG. 2. In this embodiment, it is a recessed portion formed to extend in the front-rear direction on the floor surface on the joint portion 2 side of one structure 3, and is provided with locking piles 9 that are inserted into pile cases 8 provided at both ends on the front and rear sides of one end portion of the floor joint plate 7 described later. In addition, a metal member such as a substantially angled or substantially crank-shaped member may be fixed to the wall surface on the joint portion 2 side of one structure 3 to serve as the first joint plate support portion 5.

[0022] A second joint plate support portion 6 is formed on the other structure 4. This second joint plate support portion 6 is formed to have a length such that the floor joint plate 7 can slide in the left-right direction during an earthquake. In addition, a rising inclined surface 10 on which the floor joint plate 7 rises is formed at the end portion of the second joint plate support portion 6 on the side opposite to the joint portion 2 when the joint portion 2 becomes narrower due to an earthquake.

[0023] Now, a plurality of the floor joint plates 7 of the present invention used in this floor joint device 1 are provided. In normal times, as shown in FIGS. 1 and 2, a locking pile 9 provided on the first joint plate support portion 5 is inserted into a pile case 8 formed at one end, and one end is supported in the attached state, and the other end is directly or indirectly (via a support plate or the like) supported by the second joint plate support portion 6, and a plurality of them are provided in the longitudinal direction of the joint portion 2 with substantially no gap. In FIG. 1, four floor joint plates 7 are arranged, but the number is not limited.

[0024] This floor joint plate 7 is composed of, for example, as shown in FIGS. 4 to 6, a shallow dish-shaped joint plate main body 11, a reinforcing member 12 provided inside the joint plate main body 11, a plurality of fixing means 13 for fixing the reinforcing member to the joint plate main body 11, a filling member 14 such as mortar or concrete filled inside the joint plate main body 11, a decorative plate 15 such as a tile of marble or a brick pasted on the upper surface of this filling member 14, a pile case 8 provided at both ends in the longitudinal direction on one end side of the joint plate main body 11, and a cover plate 17 attached to the other end side of the joint plate main body 11 via a hinge member 16.

[0025] The reinforcing member 12 is formed by combining a large number of plate-shaped members 12a or bar-shaped members 12b in a substantially lattice shape in a plan view (see, for example, FIG. 1). In the present embodiment, it is composed of a plurality of plate-shaped members 12a extending in the longitudinal direction of the joint plate main body 11 and substantially round bar-shaped bar members 12b provided so as to be substantially orthogonal to the plate-shaped members 12a and fixed by welding or the like to connect the plurality of plate-shaped members 12a, and has a shape like so-called grating (see FIGS. 3 and 5).

[0026] The fixing means 13 is composed of a large number of bolts 18 fixed to the inner bottom surface of the joint plate main body 11 via a welding portion for joining the joint plate main body formed at the tip of the lower end, and a fixture main body 19 attached to the bolt 18 for fixing the reinforcing member 12 (see, for example, FIGS. 3 and 6).

[0027] This bolt 18 is a bolt without a head. In this embodiment, a so-called stud bolt is used. A protruding welded portion 18a smaller than the diameter of the bolt 18 is formed at the lower end of the bolt 18 on the side opposite to the non-welded portion on the upper end side (see, for example, FIG. 3). By melting this small protruding welded portion 18a with a burner, current, etc., the bolt 18 is fixed to the inner bottom surface of the joint plate body 11. Additionally, on the lower surface of the lower end of the bolt 18, a small protruding welded portion 18a for joining the joint plate body is formed. Therefore, by melting the welded portion 18a formed at the lower end of the bolt 18 and fixing the bolt 18 to the bottom of the joint plate body 11, it is possible to prevent heat sufficient to burn the material from being transmitted to the bottom of the joint plate body 11, and it is possible to prevent burn marks from occurring on the outer bottom of the joint plate body 11 (the bottom surface of the joint plate body 7).

[0028] Incidentally, regarding the size, shape, and protruding amount of the welded portion 18a, preferably, it is sufficient that the bolt 18 can be fixed and no burn marks occur on the bottom of the joint plate 7 (the outer bottom of the joint plate body 11) when melted.

[0029] The fixture body 19 is a metal fitting such as a grating clip formed in a substantially M-shaped cross-section and a substantially hat-shaped steel cross-section. It is arranged so as to span the upper ends of the adjacent plate-like members 12a or bar members 12b, and is fixed to the joint plate body 11 by pressing the plate-like members 12a or bar members 12b from above to below.

[0030] Specifically, the fixture body 19 is composed of an engaging portion 19a provided on the left and right of the fixture body 19 and engaging with the upper ends of the plate-like members 12a or bar members 12b, and a bolt through-hole 19b provided at a substantially central portion of the fixture body 19. By passing the bolt 18 through this bolt through-hole 19b and screwing the nut 18b, the plate-like members 12a or bar members 12b are pressed from above to below, and the reinforcing member 12 is fixed to the joint plate body 11.

[0031] Incidentally, as shown in FIGS. 7 to 10, the method 20 for manufacturing a floor joint plate of the present invention for manufacturing such a floor joint plate 7 includes a bolt fixing step 21 of fixing a large number of bolts 18 in parallel on the inner bottom surface inside the shallow dish-shaped joint plate body 11, a reinforcing member arranging step 22 of arranging a lattice-shaped reinforcing member 12 as a whole inside the joint plate body 11, a reinforcing member fixing step 23 of fixing the reinforcing member 12 by a plurality of fixing means 13, and a filling step 24 of filling a filling member 14 inside the joint plate body 11.

[0032] In the bolt fixing step 21, it is a step of melting a small protrusion-shaped welding part 18a for joining the joint plate body formed at the lower end of the bolt 18 by an electric current or the like and fixing (welding) the bolt 18 to the inner bottom surface of the joint plate body 11. As a method of melting and fixing by an electric current or the like, resistance welding such as projection welding and spot welding can be considered. Although it is desirable to fix the bolt by such resistance welding or the like, any method can be used as long as it can weld to the base material of the joint plate body 11 without transmitting high heat that changes the base material.

[0033] The reinforcing member arranging step 22 is a step of arranging the reinforcing member 12 inside the joint plate body 11. In the present embodiment, the reinforcing member arranging step 22 is performed after the bolt fixing step 21, but the reinforcing member arranging step 22 can also be performed first.

[0034] In the reinforcing member fixing step 23, the bolt 18 is passed through a bolt through hole 19b provided in the substantially central portion of the fixture body 19, and a nut is screwed, so that the plate-shaped member 12a or bar-shaped member 12b of the reinforcing member 12 is pressed from above to below (the inner bottom surface of the joint plate body 11), and the reinforcing member 12 is fixed to the joint plate body 11.

[0035] In the filling step 24, it is a step of filling a filling member 14 such as mortar or concrete inside the joint plate body 11 in which the reinforcing member 12 is fixed. In this step, a decorative plate 15 may be provided as needed so as to be flat with the upper surface of the joint plate body 11.

[0036] In addition to these steps, a cover plate mounting step of providing the cover plate 17 may be separately performed.

[0037] When the main bodies 3 and 4 swing in the left - right direction due to an earthquake and the joint part 2 becomes narrower, as shown in FIG. 11, the floor joint device 1 of the present invention has the floor joint plate 7 ride up on the upward - sloping surface 10 of the second joint plate support part 6 to absorb the swinging movement due to the earthquake.

[0038] When the main bodies 3 and 4 swing in the left - right direction due to an earthquake and the joint part 2 becomes wider, as shown in FIG. 12, the floor joint device 1 of the present invention has the floor joint plate 7 slide in the left - right direction on the second joint plate support part 6 to absorb the swinging movement due to the earthquake.

[0039] In the embodiment of the present invention, a reinforcing member having a substantially lattice - shaped pattern in plan view is used. However, a plurality of plate - shaped members extending in the longitudinal direction of the floor joint plate may be fixed to be used as the reinforcing member, or a reinforcing member in which the plate - shaped members are combined into a honeycomb shape or the like may also be used.
