Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor plate support for supporting tarmac on a floor plate of a building at a predetermined height. 2. Description of the Related Art FIG. 3 shows a state in which a floor plate (b) is supported by a conventional floor plate support (a).
(A) is placed at an appropriate position on the concrete floor (c) and stands upright, supporting the tarki (d) on which the floorboard (b) is placed. The floor plate support (a) has an adjusting screw (e), and the height H can be adjusted by rotating the adjusting screw (e). When the height H has reached the predetermined value, the fixing nut (F) is tightened to lock the adjusting screw (E) so that the height H does not change. [0003] By the way, in order to support one turkey (d), it is necessary to arrange it at both ends even if it is short, and if it becomes a certain length, it is necessary to arrange several pieces. If it becomes a house, the number of required floor plate supports (a) will be very large, and these height adjustment work will take a lot of time,
This has led to higher costs. The floor panel support (a) supports the turkey (d) on which the floor panel (b) is mounted at an appropriate height H, and enhances soundproofing and vibration-proofing effects by reducing vibration and impact of the floor. It is necessary, and for that purpose, it is necessary to reduce the interval between the floor plate supports (a), (a), and arrange a large number of them. Therefore, conventionally, various floor plate supports (a) have been developed which are arranged efficiently and whose height can be easily adjusted. For example, there is a "floor plate adjusting supporter" according to Japanese Utility Model Publication No. 54-43536 and a "stopper structure for floor plate support" according to Utility Model Registration No. 3046733. As described above, various floor panel supports are known, and each has its own characteristics. For example, in the case of the floor panel support shown in FIG. 3, in order to adjust the height H, the adjusting screw (e) must be rotated, and there is a large difference between the height of the turkey (d). In this case, it takes a very long time to rotate the adjusting screw (e). A wooden square base (g) is attached to the upper end of the adjusting screw (e).
It must be set so that it is not oblique to. However, the adjustment screw screwed into the screw hole of the support base (h)
In (e), at the time of the last adjustment, the direction of the support base (h) pressed and fixed to the concrete floor (c) cannot be changed, and the direction of the base (g) becomes oblique. . As described above, the conventional floor panel support has the above-mentioned problems. The problems to be solved by the present invention are these problems, and a floor plate support having a simple structure and excellent workability in height adjustment is provided. [0007] The floor panel support of the present invention has a simple structure, the height adjustment operation can be performed in a short time, and a wooden board is used at the time of final adjustment. The feature is that it can be set so that the direction of the square base is not oblique to tarki. Therefore, the floor plate support comprises a support base, an adjuster screw, and a plate holder. By the way, the plate holder has a square base attached to its upper end, the outer periphery constitutes a spline shaft, and a convex portion and a concave portion which are parallel to the shaft are provided, and the convex portion has a tooth shape formed at equal intervals. I have. The hole of the adjuster screw is formed as a spline hole, and the plate holder fits into the hole. By rotating the adjuster screw, it can mesh with the tooth shape formed on the projection of the spline hole. That is, when the spline of the plate holder is fitted in the spline hole of the adjuster screw, the plate holder can be extended and contracted, but cannot be extended or contracted if it is rotated to mesh the tooth profile. A screw is formed on the outer periphery of the adjuster screw, and the screw is screwed into a screw hole provided in the support base. However, an insert nut is fitted to the support base, an adjuster screw is screwed into a screw hole of the insert nut, and a lock nut is screwed to the adjuster screw. If the lock nut is rotated and tightened to the insert nut, the adjuster screw cannot be rotated. When the floor support of the present invention is set, the plate holder is slid and extended with respect to the adjuster screw so that the square base at the upper end contacts the lower surface of the tartar. If the plate holder is rotated and meshes with the tooth profile of the adjuster screw, it is held at a predetermined position so as not to drop. In this case, the square base at the upper end is set so as not to be oblique to the tark. Then, fine adjustment is made by rotating the adjuster screw, and the plate holder can be raised without rotating, and can be contacted without leaving a gap between the bottom surface of the tarki and the square base. When the square base abuts,
The lock nut is tightened so that the adjuster screw does not rotate and the plate holder does not descend. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings. FIG. 1 shows an embodiment of a floor panel support according to the present invention, in which 1 is a support base, 2 is a plate holder, 3 is an adjuster screw, 4 is an insert nut, and 5 is an insert nut. Indicates a lock nut. The support base 1 stands on the concrete floor surface, the lower surface 6 is provided with an adhesive so as not to be displaced, and a wooden square base 7 screwed to a pedestal 9 formed at the upper end of the plate holder 2 is provided. As shown in FIG. 3, it can be supported against the bottom surface of the tark. The plate holder 2 with the square base 7 attached to the upper end can expand and contract in the vertical direction. For this reason, a spline is formed on the outer periphery of the plate holder 2, and this spline is inserted into a spline hole of the adjuster screw 3. I'm stuck. FIG. 2 shows a cross section in the case where the plate holder 2 is fitted in the spline hole of the adjuster screw 3. As shown in FIG. 2A, the plate holder 2 is in a free state and fitted in the spline hole of the adjuster screw 3. Can expand and contract. FIG. 2B shows a state in which the plate holder 2 is locked, and cannot be expanded or contracted. .. Are formed at equal intervals on the spline projections 10 of the plate holder 2, and the projections 12 of the spline holes are also provided with the tooth profiles 13 at the same pitch. Therefore, if the plate holder 2 is rotated from the state shown in FIG.
The plates 1 and 13 are engaged with each other and locked, so that the plate holder 2 cannot expand and contract and does not drop. Therefore, the plate holder 2 can be extended in the free state shown in FIG. 3A so that the square base 7 at the upper end can be brought into contact with or close to the lower surface of the tarrchy. This can be quickly operated by lifting and stretching the plate holder 2, and is rotated so as not to drop when it comes into contact with the plate holder 2 to be in a locked state. After the square base 7 comes into contact with the bottom surface of the tark, the height of the plate holder 2 is finely adjusted by rotating the adjuster screw 3 so that no gap is left between the square plate 7 and the bottom surface of the tark. At this time, the plate holder 2 is held by hand so as not to drop. A screw 14 is formed on the outer periphery of the adjuster screw 3, and the screw 14 is screwed to the insert nut 4. Insert nut 4 is support base 1
Is fitted in a seat formed at the upper end of a through hole 8 provided at the center of the hole. Therefore, even if the adjuster screw 3 is rotated, the plate holder 2 is raised without rotating, and the square base 7 can abut on the tark without changing its direction. As described above, the floor plate support of the present invention has a spline-formed plate holder fitted in the spline hole of the adjuster screw, and this adjuster screw is screwed into an insert nut fitted in the support base. The following effects can be obtained. The floor panel support of the present invention is held so that the plate holder is stretched to bring the square base into contact with the lower surface of the tarki, and that the floor support does not drop if it rotates. Then, by rotating the adjuster nut, the plate holder rises without turning, and comes into contact with the bottom surface of the tarki. That is, the work of attaching the floor plate support can be performed in a short time, and the wooden square base at the upper end of the plate holder can be set without tilting its direction with respect to tarki.
