Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a floor joint cover body that has a drainage function and can be easily attached to and detached from a receiving frame.
[0002]
[Prior art]
A floor joint cover device that covers a joint formed between adjacent floors and that can use a thick cover body was previously devised by the applicant of the present application. -74704.
[0003]
The floor joint cover device will be briefly described with reference to FIG.
The fixed frames a and a fixed on the left and right floors f and f adjacent to each other through the joint s are connected to the outer ends of the fixed frames a and a through the rotation mechanisms j and j so as to be opened and closed. Then, the receiving frames d, d are constituted by the movable frames c, c having the upper side covers b, b, and both end edges g, g of the cover e are slidably supported by the fixed frames a, a. In addition, the side cover b, b is attached to the upper surface of the cover frame e so that the cover body e is passed between the receiving frame bodies d, d, and the joint s is covered with the cover body e. Further, springs r, r each having one end fixed to the fixed frame a are interposed between the fixed frames a, a and the left and right side edges of the cover body e, and the cover body e is jointed by its elastic force. The center position of s is held.
[0004]
Here, since the thickness of the cover body e can be arbitrarily set, a thick cover body e having a configuration capable of filling the floor finishing material i in the shallow box frame h can be used, The cover body e can be attached and detached in a state where the movable frames c and c are rotated upward via the rotation mechanisms j and j. For this reason, the operation gaps k and k that can rotate the movable frames c and c are formed between the movable frames c and c and the floor surface of the side portion thereof. The operation gaps k and k are shielded.
[0005]
[Problems to be solved by the invention]
By the way, although the conventional floor joint cover apparatus which consists of such a structure is suitable for the use in artificial ground, it does not have the drainage function which guides and discharges sewage etc. from the floor surface into the joint s. In contrast, conventionally, a water stop plate p is stretched between the joints s to prevent inflow of sewage or the like into the joints s.
[0006]
Here, if the water stop plate p is removed and a water basin is disposed in the joint s, and the movable frames c and c are removed and a water passage gap communicating with the joint s is opened, It is possible to drain the sewage and the like from the water gap to the water trough, but if the movable frames c and c are removed, a large opening is formed, and there is a risk that a pedestrian will be taken. The springs r, r disposed below the movable frames c, c are completely visible and have poor appearance.
[0007]
Further, since the springs r and r are interposed in a compressed state between the fixed frames a and a and the left and right edges of the cover body e, the cover body e is attached to the receiving frame bodies d and d. At times, the springs r and r need to be compressed and held, and in this state, the cover body e needs to be passed between the receiving frame bodies d and d, so that the mounting operation is extremely troublesome. It was.
[0008]
Furthermore, when removing the cover body e for maintenance inspection or replacement, the movable frames c and c cannot be rotated upward unless the sealing material n filled in the operation gaps k and k is removed. Since the operation gaps k and k are backfilled again with the sealing material n after the work, the work of attaching and detaching the cover body e at the time of maintenance inspection or replacement is troublesome.
[0009]
An object of the present invention is to provide a floor joint cover body that has a drainage function and can be easily attached to and detached from the receiving frame.
[0010]
[Means for Solving the Problems]
The present invention provides a movable water-permeable side body that can be moved back and forth along the width direction of the joint, on the left and right side edges of the cover main body that is passed to the left and right floors adjacent to each other through the joint and covers the joint. It is characterized by being arranged so as to always be urged outward through the urging means.
[0011]
In such means, an appropriate number of edge side plates are arranged at predetermined intervals along the left and right side edges of the cover main body, and a plurality of sliding shaft bases are fixed to each edge side plate,
A series of through-holes that coincide in the width direction with an edge side plate positioned inside the edge side plate to which the sliding shaft is fixed, a left and right end plate of the cover main body, and a bearing plate arranged to face the inside of the both end plates. The sliding shafts are inserted into the series of through holes so as to be able to advance and retreat, respectively, and are prevented from being removed via retaining means, and further between the sliding shafts and the bearing plate. A configuration in which the movable water passing side body is configured by always biasing each sliding shaft outward through biasing means including an interposed spring member can be proposed as a preferred embodiment. . Here, the edging side plate may be single or plural.
[0012]
Further, in the above-described embodiment, a single or a plurality of sub-edging side plates are interposed at arbitrary positions between each of the edge-side plates and the left and right end plates of the cover main body, and the sub-edging side plates are adjacent to each other. In addition, the movable water-passing side body can be configured such that a through-hole through which the sliding shaft of the other edge-side plate is inserted is formed in the sub-edge-side plate.
[0013]
In this configuration, since a water passage gap is formed by an appropriate number of border side plates constituting the movable water passage side body disposed on the left and right side edges of the cover main body, rainwater and The floor cleaning sewage can be drained into the joint.
[0014]
Moreover, since the large edge part does not arise in the right-and-left side edge part of a cover main body with the edging side board of the said movable water flow side part body, dangers, such as a pedestrian taking a leg, are prevented.
[0015]
Furthermore, the cover main body can be mounted simply by attaching it to the left and right receiving frames from above, and can be opened simply by pulling it up, so that it can be easily attached and detached.
[0016]
In addition, when the adjacent left and right floors are relatively displaced in the direction of narrowing the joint width, the movable water-permeable side body contracts and can absorb the relative displacement. The urging means comprising a spring member that constantly urges the outer side outward is disposed inside the main body of the cover, and the urging means cannot be seen from the outside, so that the appearance is good.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS.
In the drawing, f and f are left and right floors constituting an artificial ground, and are adjacent to each other through a joint s. In the corners B and B of the floors f and f, a pair of receiving frames 2 and 2 are disposed along the longitudinal direction of the joint s. The receiving frames 2 and 2 are formed in an L-shaped section by vertical edges 2a and 2a and horizontal receiving edges 2b and 2b projecting inwardly at the lower ends of the vertical edges 2a and 2a. Are fixed to the floors f and f.
[0018]
At the lower position of the inner ends of the horizontal receiving edges 2b, 2b, L-shaped support plates 5, 5 are fixed to side edge plates 4, 4 disposed on the upper inner surface of the left and right floors f, f. The upper end edges of the guide sheets 6 and 6 having water shielding properties are fixed to the support plates 5 and 5, respectively. The lower end edges of the guide sheets 6 and 6 are suspended in a water trough (not shown) disposed in the joint s along the longitudinal direction thereof. The sewage that flows from the inside is led into the water tank.
[0019]
Then, the floor joint cover body 1 according to the present invention is handed over the receiving frames 2 and 2 to shield the joint s. The configuration of the floor joint cover body 1 will be described in detail.
[0020]
The floor joint cover body 1 includes a cover main body 7 and movable water-permeable side body bodies 8 and 8 respectively disposed on the left and right side edges of the cover main body 7. The cover main body 7 is formed into a shallow box frame shape by a bottom plate 9, left and right end plates 10, 10 and front and rear end plates 11, 11 surrounding the periphery, and the inside thereof is partitioned vertically by a partition plate 12. Thus, a working gap 14 is formed in the lower part of the recess 13 where the floor finishing material 23 such as mortar m is filled. In the working gap 14, a pair of bearing plates 15a and 15b arranged at predetermined intervals on both the left and right sides thereof are arranged to face the left and right end plates 10 and 10, respectively.
[0021]
On the other hand, in the present embodiment, three edge side plates 16a, 16b, and 16c are arranged along the left and right end plates 10 and 10 of the cover main body 7 in order from the outside. As shown in FIG. 2, the bases of the plurality of sliding shafts 17 are fixed to the respective edge side plates 16a, 16b, and 16c.
[0022]
Further, the edge side plates 16b, 16c positioned inside the edge side plates 16a, 16b, 16c to which the sliding shafts 17 are fixed, that is, the edge side plates 16b, 16c for the edge side plate 16a and the edge side plate 16c for the edge side plate 16b, and The sliding left and right side plates 16a, 16b, 16c are fixed to the left and right end plates 10, 10 of the cover main body 7 and the bearing plates 15a, 15b disposed opposite to the inner sides of the both end plates 10, 10, respectively. A series of through-holes 18 that coincide in the width direction through which the shaft 17 can be inserted are formed.
[0023]
The sliding shafts 17 are inserted into the series of through-holes 18 so as to be able to advance and retreat, and the sliding shafts 17 are prevented from being detached by retaining means. The retaining means is constituted by fitting a fitting ring 19 at a predetermined position of each sliding shaft 17, and the fitting ring 19 is located outside the bearing plates 15a and 15b. By making contact with the inner side surface of the plate 15a, the sliding shaft 17 is prevented from coming off.
[0024]
Further, each sliding shaft 17 is fitted with a spring member 20 made of a coil spring as biasing means. Each spring member 20 is interposed in a compressed state between the fitting ring 19 and the bearing plate 15b positioned on the inside, and the elastic force of the spring member 20 causes each sliding shaft 7 to be always outside. I'm trying to urge you.
[0025]
Further, as shown in FIG. 2, the bases of the plurality of leg rods 21 are fixed to the lower side surfaces of the respective edge side plates 16a, 16b, 16c for each of the edge side plates 16a, 16b, 16c. The tip ends of 21 are horizontally extended inward and are in sliding contact with the lower surface of the bottom plate 9 of the cover main body 7.
[0026]
Thus, the movable water flow that can be moved back and forth along the width direction of the joint and is always urged outward by the edge side plates 16a, 16b, 16c, the sliding shaft 17, the retaining means, the urging means and the like. Side bodies 8, 8 are configured. In addition, a plurality of water passages 22 are formed between the edge side plates 16a, 16b, and 16c and between the edge side plate 16c and the end plate 10 of the cover main body 7.
[0027]
Further, the concave portion 13 of the cover main body 7 is filled with the floor finishing material 23 made of the same mortar m and tile t as the floor finishing material 23 laid on the surrounding floors f and f.
[0028]
Thereby, the joint joint body 1 for floors is comprised. Then, the floor joint cover body 1 is attached to the left and right receiving frames 2 and 2 from above, and the leg rods 21 are supported by the horizontal receiving edges 2b and 2b of the receiving frames 2 and 2, as shown in FIG. The joint s is covered by passing between the receiving frames 2 and 2. Here, the horizontal width of the floor joint cover body 1 is substantially the same as the interval between the vertical edges 2a and 2a of the left and right receiving frames 2 and 2, and the floor joint cover body 1 is covered by the receiving frames 2 and 2. When worn, the left and right edge side plates 16a, 16a located on the outermost side are close to the vertical edges 2a, 2a of the receiving frames 2, 2. Further, in this state, a water passing gap 24 is generated by the leg rod 21 between the bottom plate 9 of the cover main body 7 and the horizontal receiving edges 2b and 2b. As shown in FIG. 1, buffer members 25, 25 made of rubber plates are laid on the upper surfaces of the horizontal receiving edges 2b, 2b, and leg rods 21 are mounted on the buffer members 25, 25. Good.
[0029]
The floor joint cover body 1 is formed to have a predetermined length, and a plurality of floor joint cover bodies 1 are continuously arranged along the joint s.
[0030]
In this attached state, a water passage from the water gap 22 into the joint s is formed by the water gap 22 and the gap 24 generated by the leg rod 21. Then, the rain water on the surrounding floors f, f and the floor joint cover body 1 or the sewage for cleaning the floor can be drained by flowing into the drainage basin in the joint s through the water passage.
[0031]
Further, when the floor joint cover body 1 is attached or detached during maintenance inspection or replacement, or when cleaning the water passage, etc., the floor joint cover body 1 is covered by the left and right receiving frames 2 and 2 from above. Since it is only worn, it can be opened simply by pulling it upwards and can be easily attached and detached.
[0032]
On the other hand, as a joint function as a joint cover device with respect to the relative displacement of the left and right floors f, f, when the floors f, f are relatively displaced in the direction of narrowing the joint width in the left-right direction, as shown in FIG. First, the left and right edge-side plates 16a and 16a located on the outermost side are pushed inward by the vertical edges 2a and 2a of the receiving frames 2 and 2, respectively, and move inward to contact the edge-side plates 16b and 16b located on the inside thereof. Further, when the edge side plates 16a, 16a are pushed by the vertical edges 2a, 2a, as shown in FIG. 4, the edge side plates 16b, 16b are pushed together with the edge side plates 16a, 16a to move inwardly, It abuts on the bordered side plates 16c, 16c. Further, when the edge side plates 16a and 16a are pushed by the vertical edges 2a and 2a, as shown in FIG. 5, the edge side plates 16b and 16b and the edge side plates 16c and 16c are pushed inward along with the edge side plates 16a and 16a. To contact the end plates 10 and 10 of the cover main body 7. Thereby, the relative displacement in the direction of narrowing the joint width of the floors f and f is absorbed. And each edge | side edge side board 16a, 16b, 16c is always urged | biased by the spring member 20, respectively, and when the floors f and f on either side return to an old position, each edge side board 16a, 16b, 16c will also be. Return to the old position. Further, the floor joint cover body 1 is held at the center position of the joint s by the elastic force of the spring member 20.
[0033]
On the other hand, when the floors f and f are relatively displaced in the direction of expanding the joint width in the left-right direction, the floor joint cover body 1 is placed on the horizontal receiving edges 2b and 2b of the receiving frames 2 and 2 via the leg rods 21. , And the floor joint cover body 1 and the receiving frames 2 and 2 move relatively to the left and right to follow relative displacement in the direction of widening the joint width of the floors f and f.
[0034]
On the other hand, when the floors f, f are relatively displaced in the front-rear direction (the direction along the joint s), the floor joint cover body 1 moves on the horizontal receiving edges 2b, 2b of the receiving frames 2, 2 via the leg rods 21. The floor joint cover body 1 and the receiving frames 2 and 2 move back and forth relatively to follow the relative displacement of the floors f and f. Further, when the floors f and f are relatively displaced in the vertical direction, the floor joint cover body 1 is inclined due to the height difference between the receiving frames 2 and 2, and follows the relative displacement. Accordingly, the floor joint cover body 1 can follow the relative displacements of the floors f, f in the front-rear, left-right, and up-down directions, and can cover the joint s without hindrance.
[0035]
In the above-described embodiment, the case where the three edge side plates 16a, 16b, and 16c are respectively disposed along the left and right side edges of the cover main body 7 has been described. However, one or more appropriate number of the edge side plates are provided. It can be.
