[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a floor repair method and a floor structure according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 7, the floor structure serving as the basis of the floor repair method according to the first embodiment is a slab 4 (a concrete slab, a block slab, etc.) erected on the floor slab 2. The floor material is constructed on the floor.
[0016]
The slab stones 4 are arranged in a grid pattern on the floor slab 2, and a cushioning material 6 such as a coil spring, a ring damper, or rubber is placed on the upper surface of each slab stone 4, and is fixed to the upper part of each cushioning material 6. A large wooden member 8 is erected on the large receiving member 7 and fixed by a fastening member 9. A wooden joist 10 is placed between the large pulling materials 8 in a direction perpendicular to the wooden joist 8, and a discarded material 12 and a flooring material 14 are laid on the joist 10.
[0017]
In the floor structure according to this embodiment, when the floor structure is repaired, the shackles 4 before the repair are not horizontal with the adjacent shards, and the positions of the shards are not linearly located. There were many cases. For this reason, the height adjuster 20 shown in FIG. 1 is interposed between the bracelet 4 and the cushioning material 6 to correct the variation in the height of the bracelet 4 and stabilize the support of the cushioning material 6. As shown in FIGS. 1A, 1B, and 1C, the height adjuster 20 includes a steel upper plate portion 24, a lower plate portion 26, and support bolts 28 provided at four corners between these plate portions. And adjustment nuts 30 and 31 for adjusting the height of the upper plate portion 24.
[0018]
The lower plate portion 26 is a flat rectangular plate material, and support bolts 28 to which a head portion 36 is fixed by welding are set up near four corners. The upper plate portion 24 is a rectangular plate body, and has a groove portion 32 in the center and flange portions 34 and 35 formed on the left and right sides. The upper plate 24 has holes 33 at positions corresponding to the four corners of the lower plate 26.
[0019]
The height adjusting tool 20 is configured such that one adjusting nut 30 is screwed into an upper portion of each supporting bolt 28, each hole 33 of the upper plate portion 24 is fitted from above, and another adjusting nut 31 is further screwed into the upper plate. The part 24 is fixed. The height adjuster 20 adjusts the positions of the adjustment nuts 30 and 31 to increase or decrease the height of the upper plate portion 24.
[0020]
By the way, in the floor repair method according to this embodiment, the slab 4, the cushioning material 6, the large pulling material 8, and the joist 10 in FIG. 7 are not removed, and the floor is repaired using these materials. First, the old and old flooring material 14 and the discarded material 12 are peeled off and removed. If there is no damage on the old cushioning material 6, large pulling material 8, and joist material 10, they are reused. If there is damage, the parts are replaced with new members.
[0021]
Next, as shown in FIG. 2, the height adjuster 20 is interposed between the slab 4 and the cushioning material 6. At this time, the adhesive 76 is applied to the upper surface of the slab 4 and the height adjuster 20 is adhered and fixed. As a result, the height adjuster 20 is firmly fixed to the slab 4, and the cushioning material 6 is stably disposed in the groove 32 of the upper plate 24. The height adjuster 20 rotates the adjustment nuts 30 and 31 to move the upper plate portion 24 up and down, and adjusts the height of the large pulling member 8 and the joist member 10 supported by the upper cushioning member 6 to be constant. . After setting the horizontal reference of the entire floor in this way, a new rubbing material 13 is laid on the joist material 10 and a flooring material 15 is laid to finish.
[0022]
It should be noted that although there is another floor structure in which the cushioning material is not arranged, even with such a floor structure, as in the above embodiment, the height adjuster 20 is provided on the upper surface of the slab. It is also possible to mount and fix, and interpose the cushioning material 6 between this and the large attracting material.
[0023]
Therefore, according to the above-described embodiment, since the floor can be repaired and reused without removing the slabs, the repair cost can be reduced, and the slabs need not be turned into industrial waste. In addition, if there is no damage on the cushioning material, the large-scale lumber, the joist, etc., they are reused, so that they are not industrial waste, and the repair cost is reduced. Furthermore, in the conventional slabs, the distance between adjacent slabs is not constant, and the height of the slabs is not laid, so it was difficult to adjust the horizontal level of the floor. Since the horizontal level can be easily adjusted by fixing the tool to the slab, there is an effect that the workability of the construction is excellent, and the floor impact is favorably reduced by the cushioning material.
[0024]
Next, a floor repair method and a floor structure according to a second embodiment will be described. In this embodiment, the floor is repaired while leaving only the slab 4 in FIG. For this reason, the old and old flooring material 14 and the pasting material 12 are peeled off and removed, and the cushioning material 6, the large drawing material 8 and the joist material 10 are removed and removed.
[0025]
FIG. 3 shows a height adjuster 40 used in this embodiment. As shown in FIG. 4, the height adjuster 40 is interposed between the slab 4 arranged on the floor slab 2 and the large attracting material 82 to adjust the height of the large attracting material 82.
[0026]
As shown in FIG. 3, the height adjuster 40 includes two support bolts 44 erected on a steel substrate 42 at a predetermined interval, and a height adjustment nut screwed on the support bolts 44. 46, 47, a support plate 48 laid over these support bolts 44, a receiving member 50 welded and fixed to the upper portion of the supporting plate 48, and a bolt 52 and a nut 54 connecting the left and right upper portions of the receiving member 50. The height adjusting tool 40 adjusts the height of the support plate 48 and the receiving tool 50 by turning the adjusting nuts 46 and 47, respectively.
[0027]
The support plate 48 has a hat-shaped cross section, and has a groove 56 at the center and flanges 58 and 59 on the left and right sides. The heads 45 of the support bolts 44 are welded to the substrate 42, and they are fixed at positions offset from the center line of the support plate 48. Holes are provided in the flange portions 58 and 59 of the support plate 48 at positions deviated in the opposite direction from the center portion, and the support bolts 44 are inserted and fixed in these holes, thereby obstructing the mounting of the bolts 52 and nuts 54. I try not to be.
[0028]
The receiving member 50 is formed in a U-shaped cross section, and an elastic member 62 made of rubber, synthetic resin, or the like having a U-shaped cross section is fixed along the inner surface. In the receiving device 50, side plate portions 66 and 67 are erected from both sides of the bottom plate portion 64, and the side plate portions 66 and 67 are connected and fixed by bolts 52 and nuts 54. The substrate 42 is provided with a plurality of holes 74.
[0029]
In the floor renovation method according to this embodiment, first, the old flooring material 14 and the waste material 12 shown in FIG. 7 are peeled off, and further, the joist material 10, the large drawing material 8 and the cushioning material 6 are removed and removed. Thereafter, the floor structure shown in FIGS. 4 and 5 is constructed. First, an adhesive 76 is applied to the upper surface of the remaining slab 4, and the height adjuster 40 is bonded and fixed thereto. At this time, since the adhesive 76 gushes out from the hole 74 of the substrate 42 and covers a part of the upper surface of the substrate 2, the fixing of the height adjuster 40 becomes strong.
[0030]
Next, a large steel pulling member 82 is installed between the height adjusting tools 40. The large attracting member 82 is a rectangular tube having a rectangular cross section. The large pulling member 82 is held by the elastic member 62 in the receiving member 50, and is fastened by the bolt 52 and the nut 54 passed over the receiving member 50. The shock transmitted from the floor surface to the large pulling member 82 is reduced by the buffer effect of the elastic member 62.
[0031]
After attaching the large pulling material 82, the height of the large pulling material 82 is adjusted to be constant by turning the adjusting nuts 46 and 47 of the height adjusting tool 40, and the horizontal reference of the entire floor is set. Thereafter, a steel joist 84 having a hat-shaped cross section is arranged in a direction perpendicular to the large pulling material 82, and is fixed to the large pulling material 82 using screws 65. FIG. 6 shows a plane after the large pulling material 82 and the joist material 84 are laid, and a hatch 78 for inspection is provided as necessary. Then, a new discarded material 86 and a flooring material 88 are laid on the joist material 84 and finished.
[0032]
Therefore, according to the second embodiment, since the slabs can be reused and the floor can be repaired without removing the slabs, the repair cost can be reduced, and the slabs can be turned into industrial waste. Absent. Also, in the conventional slabs, the spacing between adjacent slabs is not constant, and the height of the slabs is not laid, which makes it difficult to adjust the horizontal level of the floor. The horizontal level can be easily adjusted by the fixture, and the workability is excellent, and the elastic material of the height adjuster has an effect of favorably reducing the floor impact.
[0033]
