Description

  The present invention relates to a floor level adjustment fitting, and more particularly to a floor level adjustment fitting that adjusts a height by moving a floor plate member upward or downward.

  The flooring material of a wooden house building, for example, a base installed on the top end surface of a concrete foundation such as a cloth foundation, a large pull installed between the foundations, or a joist provided above these as a floor board support member In addition, a floor board member such as a floor board, a floor panel, and a waste board is laid, and a floor finishing material or the like is attached to the upper surface of the floor board member. In addition, the floor level of the flooring material is influenced by the construction accuracy of the top end surface of the concrete foundation, and is also affected by the dimensional accuracy of the floorboard support member and floorboard member, drying shrinkage, etc., which are generated in the flooring material. It is a major factor such as flooring and unevenness. In particular, in recent years, buildings that employ floor heating are increasing, and floor noise when heating is operated, generation of gaps in floor joints, and the like are problematic.

As a method of adjusting the floor level of the flooring material, there are gaps between the foundation and the foundation, and between the floor board support member such as the foundation, the overdrawing, the joist, and the beam, and the floor board member such as the floor board, the floor panel, and the separation board. A method by driving wedges into the gap is generally known (see, for example, Patent Document 1). However, the shape dimensions of the wedges used and the depth of driving them are left to the experience and feeling of the workers Depending on how the wedges are driven, there may be a new gap around the wedges that are driven in, resulting in the expansion of defective parts and the occurrence of squealing or unevenness in one repair. In some cases, it could not be resolved, and it was necessary to repeat the repair twice and three times. Also, it is difficult to pull out the wedge once it has been driven.
Japanese Patent No. 34665959

  On the other hand, Patent Document 1 discloses a technique in which the height of the foundation with respect to the concrete foundation can be quantitatively adjusted by a simple operation without using a wedge, but the height of the foundation is disclosed. Only by adjusting, it is difficult to sufficiently eliminate problems such as floor squealing and unevenness that occur in the flooring material due to, for example, dimensional errors and drying shrinkage of the floorboard support member and floorboard member.

  The present invention has been made paying attention to such a conventional problem, and it is possible to adjust the height of the floor board member with respect to the floor board support member by a simple operation without using wedges.

Will be. Note that the lower nut member 15b does not necessarily have to be screwed to the male threaded portion 20 of the bolt portion 21 before the adjustment of the height of the floor plate 12 by the floor level adjusting fitting 10 is completed. After the adjustment to raise the floor plate 12 by the member 15a is finished, the lower nut member 15b is tightened so that the bolt support 18 is sandwiched between the upper nut member 15a to prevent the upper nut member 15a from loosening. You can also wear it.

  And according to the floor level adjustment fitting 10 of the present embodiment having the above-described configuration, the floor level of the floor board 12 can be easily and quantitatively adjusted by the following operations, even if it is not a skilled worker, It is possible to eliminate problems such as flooring and unevenness of flooring.

  That is, for example, when a flooring problem such as squealing or unevenness occurs after construction of a wooden house building, for example, the floor level of the flooring is measured and confirmed in advance by a measuring device such as a roboline. The location where the floor level of the floor board 12 is to be adjusted, the height adjustment amount at the adjustment location, and the like are calculated and prepared in advance as adjustment data. Then, based on the created adjustment data, for example, an operator enters under the floor and moves to each adjustment location, and the floor level adjustment fitting 10 of the present embodiment is attached to adjust the height of the floor plate 12.

  In order to adjust the height of the floor plate 12 at each adjustment location, for example, the upper nut member 15a of the bolt portion 21 of the second metal fitting 14 is first screwed into the bolt insertion hole 17 of the bolt support base 18 of the first metal fitting 13. The floor level adjusting bracket 10 is set by inserting the worn male screw portion 20. At this time, it is preferable that the nut member 15a is as close as possible to the upper end side of the male screw portion 20.

  Next, the first metal fitting 13 is attached to a predetermined position on the side surface of the base 11 using screws 25. When the first metal fitting 13 is attached, the upper nut member 15a is rotated to move downward to the bolt support base 18, and the upper nut member 15a is further rotated to move the second plate portion 19 of the second metal fitting 14 upward. Then, the upper surface of the second plate portion 19 is grounded along the lower surface of the floor plate 12.

  After the second plate portion 19 is grounded to the lower surface of the floor plate 12, if the upper nut member 15 a is further rotated while being in close contact with the bolt support base 18, the second plate portion 19 rises so as to push up the floor plate 12. Therefore, it is possible to read the amount of increase by, for example, the scale 22 or the scale plate 23 and move the floor plate 12 upward to a predetermined floor level indicated in the adjustment data.

  When the floor plate 12 is moved to a predetermined floor level, the second plate portion 19 of the second metal fitting 14 is fixed to the lower surface of the floor plate 12 with screws 25, and the lower nut member 15b is fixed to the bolt support base 18. By tightening from below, the upper nut member 15a is prevented from loosening, so that the adjusted state in which the floor level of the floor plate 12 is accurately adjusted at each adjustment location is firmly held.

  Further, for example, when the floor plate 12 is floating upward, for example, the upper nut member 15a is rotated in the direction of loosening from the above state and moved upward to be separated from the bolt support base 18, and the lower nut member 15b is If it is rotated in the tightening direction, the second plate portion 19 of the second metal fitting 14 moves downward together with the floor plate 12 to which the second metal plate 14 is fixed so as to be drawn to the bolt support base 18. Can be read by the scale 22 or the scale plate 23, for example, and the floor plate 12 can be moved downward to a predetermined floor level indicated in the adjustment data. When the floor plate 12 is lowered to a predetermined floor level, the upper nut member 15a is retightened to the bolt support 18 to prevent the lower nut member 15b from loosening, and the floor level of the floor plate 12 is adjusted with high accuracy. The adjusted state is firmly held.

  Therefore, according to the floor level adjusting bracket of the present embodiment, it is possible to adjust the height of the floor plate 12 with respect to the base 11 by a simple operation without using wedges, and floor noise or unevenness that occurs in the floor material. It is possible to effectively solve the problem.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, the floor level adjusting bracket of the present invention is not limited to the case where the height of the floor plate member of the first floor portion provided with the base or the like as the floor plate support member, but the second floor provided with the beam or the like as the floor plate support member. It can also be used to adjust the height of the floor plate member of the part and further the upper floor part. Further, the height adjustment amount of the floor plate member can be confirmed by other means such as counting the number of rotations of the nut member without using a scale or a scale plate. Furthermore, the first plate portion, the second plate portion, and the bolt support base are not necessarily square or rectangular, and may have various other shapes such as a circle, an ellipse, and a triangle.

  Further, the first metal fitting does not necessarily have to be formed by integrally joining a bolt support base to the first plate portion by welding or the like. For example, as shown in FIGS. 4 and 5, the first metal fitting is cut into a predetermined shape. The processed plate member 28 may be bent to form the first metal fitting 13 including the first plate portion 16 and the bolt support base 18. Furthermore, the bolt support base does not necessarily have to be a plate-like portion, and may have other shapes such as a hexahedral shape and a drum shape.
