Description

[0001]
[Industrial application fields]
The present invention relates to a wooden floor laying apparatus used for laying a wooden floor on a concrete slab.
[0002]
[Prior art]
For example, as described in Japanese Patent Application Laid-Open No. 11-100780, there is a structure in which a flooring is placed on a joist arranged side by side on a slab, and the flooring and joist are joined using a fitting. is there.
[0003]
In this conventional example, a groove is provided on the side surface along the longitudinal direction of the joistwood, and a fixing piece is driven into the groove with a hammer or the like to fix the jointing fixture to the joistwood. The floor material is sequentially laid so that the groove formed in the side surface along the longitudinal direction of the floor material is fitted to the piece.
[0004]
[Problems to be solved by the invention]
In the conventional example, the joist is made of relatively hard wood, and the coupling metal is driven and fixed in the fixed piece using the properties of the wood. Therefore, there is a limitation in application because the above operation cannot be performed in a region close to the wall surface.
[0005]
In other words, it has a structure in which a fitting (fixed part thereof) must be driven into a straight groove in accordance with the number of wooden floor coverings and at intervals corresponding to the width of the floor covering. Therefore, there is a possibility that a crack along the groove will occur in the joist (this will cause a problem in durability due to the occurrence of the crack). In order to avoid this crack, the wood constituting the joist is examined appropriately. And flooring with a certain width must be used.
[0006]
The present invention has been devised for the purpose of providing an easy-to-use laying apparatus, paying attention to the drawbacks of such a conventional example.
[0007]
[Means for Solving the Problems]
It comprises a pair of L-shaped pieces standing upright along the longitudinal direction, and a joist that is juxtaposed on a concrete slab so that the height can be adjusted, and the L-shaped guide piece of the joist. A side surface along the longitudinal direction of a required number of coupling pieces and an assembly groove for engaging the coupling piece, which is slidably fitted into the engaging groove at the piece and provided with a coupling piece in a direction orthogonal to the longitudinal direction. And a wooden flooring placed on the joist.
[0008]
【Example】
The drawings show an embodiment of a wooden floor laying apparatus according to the present invention, FIG. 1 is a partially cutaway front view, FIG. 2 is an enlarged sectional view taken along the line aa of FIG. 1, and FIG. FIG. 4 is a side view of the coupling piece.
[0009]
In the present invention, a wooden flooring 3 is placed on a joisting material 1 using a connecting piece 2 slidably fitted to the joisting material 1 by arranging joisting materials 1 made of extruded aluminum material on a concrete slab b. Are connected to the joist member 1 and are installed on the upper and lower pieces 4a and 4b of the hollow main body 4 having a rectangular cross section. A pair of L-shaped pieces 5, 5, 6 and 6 are provided so as to project from each other, and the upper engaging grooves 7 and 7 formed by the upper L-shaped pieces 5 and 5 and the upper piece 4a are coupled to each other. The piece 2 is slid and assembled in the pieces 8 and 8, and the nut material 10 is engaged in the lower engaging groove 9 formed by the lower L-shaped pieces 6 and 6 and the lower piece 4b. is there.
[0010]
The nut member 10 is formed of a rectangular metal plate provided with a screw hole 11 at the substantially center, and is engaged with the engaging groove 9 as described above so that both ends are positioned at the inner end of the upper engaging groove 9. By configuring it in a square shape, even if an external force is applied in the rotational direction centering on the screw hole 11, the rotation is restricted against the inner wall of the engagement groove 9.
[0011]
A receiving bolt 12 is screwed into the screw hole 11 of the nut material 10 from the lower side of the nut material 10, and the tip of the bolt 12 is passed through the through hole 13 provided in the lower piece 4 b that overlaps the nut material 10. 4, and a fastening nut 15 is screwed through a washer 14.
[0012]
The receiving bolt 12 is provided with a tool (driver) locking groove 16 at a distal end portion disposed in the hollow main body 4, and the tool is passed through the window hole 17 formed in the upper piece 4 a of the hollow main body 4 in the locking groove 16. When the bolt 12 is rotated while the tip is locked, the nut material 10 whose rotation is restricted by the joist member 1 is screwed to the receiving bolt 12, so that the nut material 10 is assembled in the engagement groove 9 portion. As a result, the up / down adjustment operation of the joist member 1 is performed, and as a result, the tightening nut 15 is passed through the window hole 17 through the washer 14 and the lower piece 4b. The adjustment height of the joist 1 is maintained by tightening to.
[0013]
The connecting piece 2 is a substantially flat vertical piece in which the plate width of the lower portion 18b is narrower than the gap width between the tips of the upper L-shaped pieces 5 and 5 of the joist member 1, and the plate width of the upper portion 18a is increased. A pair of left and right connecting pieces 19, 19, which are placed in the shape of a wing piece with respect to the vertical piece 18, are connected to the upper end of the upper portion 18 a by placing an upper plate having the same width as the upper portion 18 a. A lower plate is connected to the lower end of the piece 18 so as to face the coupling pieces 19, 19, and a portion of the lower plate located immediately below the upper portion 18 a of the vertical piece 18 is the piece 8. The connecting piece 19 is engaged with the assembly groove 20 provided on the side surface along the longitudinal direction of the flooring 3, and the piece 8 is formed in the upper engaging groove 7 provided on the connecting piece 2. The sliding fit is as described above.
[0014]
21 is a thick portion provided at the lower end of the upper portion 18a of the vertical piece 18 of the connecting piece 2. The thick portion 21 is interposed between the floor materials 3 and 3 and functions as a spacer.
[0015]
Accordingly, the window hole 17 and the through-hole 13 are formed at appropriate positions on the joist material 1 so that the nut material 10 is disposed at a position such as the window hole 17 so as to be slidably fitted into the engagement groove 9. Then, the receiving bolt 12 is screwed into the screw hole 11, the washer 14 and the tightening nut 15 are assembled to the receiving bolt 12, and the bolt 12 is rotated using the locking groove 16. Moves longitudinally with the joist 1 and, as a result, the joist 1 is set at a required height position, and the set position is maintained by tightening the tightening nut 15.
[0016]
In this way, the joists 1 are arranged at the required positions on the concrete slab b and arranged side by side, and the joists 8 are slidably fitted into the upper engaging grooves 7 on the joists 1 so that the required number of connections are made. The piece 2 is assembled, the flooring 1 is placed on the joist member 1 so that the assembling groove 20 is engaged with the coupling piece 19 of the coupling piece 2, and sequentially assembled and laid.
[0017]
【The invention's effect】
As described above, the present invention employs a structure in which the coupling piece is slidably assembled to the joist material, so that it can be applied without any trouble even in the vicinity of the wall surface by pre-assembling the coupling piece to the joist material. There are no (location) restrictions.
[0018]
Of course, during the laying operation, the members can be assembled with each other without damaging the members, so that the floor material can be laid, so that a floor device as designed can always be obtained.
