However, in a wooden floor bundle, since the height of the bundle cannot be adjusted, there has been a problem that the floor squeaks due to deformation or the like due to drying of the wood, causing floor noise. Further, the wooden floor bundle has a problem that the life thereof is short because the wooden floor bundle is likely to deteriorate over time and may be damaged by termites.

As this type of floor bundle, for example, a floor bundle having a turnbuckle-structure floor bundle main body in which screw rods each having a right-handed screw or a left-handed screw engraved at both ends of a columnar support rod are respectively screwed. Kaihei 6-

面倒でコストが嵩むという問題もあった。However, in the conventional steel floor bundles, since the shape of the supporting rod and the bundle height adjusting bracket are all different in the outer peripheral cross-sectional shape between the upper and lower end portions and the intermediate portion, a spanner or the like is required. However, there is a problem that the portion for engaging the tool becomes narrow, and height adjustment is troublesome. Further, there is also a problem that the production of the supporting rod or the frame-shaped bundle height adjusting bracket having the small diameter at the upper and lower ends is troublesome and increases the cost.

A receiving member, and a base member for erecting a lower screw rod for engraving the other external thread portion of either the right-hand thread or the left-hand thread on the upper surface,
The first screw which is screwed into the male screw part of the upper and lower screw rods respectively
And a cylindrical adjusting member having a polygonal cross-section on the outer periphery for engraving the second female screw portion at both ends.

Item 2). Further, it is preferable that the cylindrical adjusting member is formed of an extruded aluminum member (claim 3).
Here, aluminum includes aluminum or an aluminum alloy, but is preferably, for example, JI
S2000, 3000, 5000, 6000 or 7000 aluminum alloys are better.

１）。With this configuration, since the outer periphery of the cylindrical adjusting member has a polygonal cross section, a tool such as a wrench is engaged with any part of the cylindrical adjusting member to rotate the cylindrical adjusting member. Can be done. Therefore, since a portion for engaging a tool such as a wrench is wide, even in a small underfloor space, it is possible to easily perform a large-scale height adjustment and to facilitate construction (claim 1).

未満であると、雌ねじの加工が困難となるためである。In this case, one or a plurality of drainage grooves are formed in the inner peripheral surface of the through hole including the first and second female threads of the cylindrical adjusting member so as to extend longitudinally, so that the inside thereof is formed by dew condensation. The generated water can be discharged to the outside through the drain groove, and the female screw can be easily cut. Further, by forming the cylindrical adjusting member from an extruded aluminum member, the cylindrical adjusting member can be easily processed. In addition, the cylindrical adjusting member can be provided with corrosion resistance as compared with a steel-made member, can be reduced in weight, and can have strength resistance as compared with a wooden or plastic member. Further, by using a hollow extruded shape, it is not necessary to perform a pilot hole processing at the time of thread cutting. In this case, the hole diameter of the hollow part is 95% of the nominal diameter of the male screw.
It is desirable that the diameter be less than 60% or more. If it is more than 95%, it becomes impossible to cut the internal thread,
If it is less than this, it becomes difficult to machine the female screw.

を防止することができるからである。On the other hand, the cylindrical adjusting member 40 (hereinafter referred to as the adjusting member 40) is formed of an extruded member made of aluminum, for example, an aluminum alloy such as JIS6063 or the like having an outer periphery having a hexagonal cross section. At one end (upper end) of the adjusting member 40, a first female screw 41 to be screwed with the male screw 21 of the upper screw rod 22 is engraved, and at the other end (lower end), a lower end is provided. A second female screw portion 42 is screwed into the male screw portion 31 of the screw rod 32. Further, one or more (three in the drawing) drainage grooves 44 are formed in the inner peripheral surface of the through-hole 43 including the first and second female screw portions 41 and 42 of the adjusting member 40 in a longitudinally extending shape. Is formed.
In this case, the position where the drain groove 44 is provided may be arbitrary,
It is preferable to provide the drain groove 44 in the thick part of the corner of the outer periphery of the adjusting member 40. The reason is that the drain groove 44
The reason for this is that the strength of the adjustment member 40 can be prevented from being impaired.

Also, the height adjustment can be facilitated by easily turning the adjustment member 40. In addition, by forming the adjusting member 40 with an extruded shape member made of aluminum, the adjusting member 40 can have corrosion resistance and can be easily processed. Further, by forming a drainage groove 44 in the inner peripheral surface of the through hole 43 including the first and second female screw portions 41 and 42 so as to extend longitudinally, water collected in the hollow portion of the adjusting member 40 due to dew condensation. Can be discharged outside.

It is desirable that the strength of the steel upper screw rod 22 and the steel lower screw rod 32 of the base member 30 and the strength of the aluminum adjustment member 40 be the same as a whole. Therefore, in the present invention, a material having a higher Young's modulus than aluminum is used for the upper and lower screw rods 22 and 32.

Therefore, the overall rigidity can be made uniform and the strength can be improved. In the above example, when an aluminum screw rod is used, the rigidity of the screw rod portion is 1.7 × 10 8 Nmm 2 and the adjusting member 4
0, which is about 1/3 of the stiffness, and uniform stiffness cannot be achieved as a whole bundle.

Electric erosion occurs between them. So, on,
By applying a metal film made of a material other than aluminum, for example, a Zn film 70 to the lower screw rods 22 and 32, electrolytic corrosion of aluminum is prevented and the life is extended.

At this time, lock nuts 51 and 52 are provided on both ends of the adjusting member 40, and these lock nuts 51 and 52 are screwed to the upper screw rod 22 and the lower screw rod 32 in advance. Next, the substrate 33 of the base member 30 is placed on the foundation concrete surface, the large pull 60 is placed on the placing piece 23 of the large receiving member 20, and the large pull 60 is placed with a wood screw (not shown). It is fixed to the piece 23 and the standing piece 24. In this state, a tool such as a wrench is engaged with the adjusting member 40, and the adjusting member 40 is rotated rightward or leftward to adjust the height of the large pulling 60. After the height position of the puller 60 is determined in this manner, finally, both the lock nuts 51 and 52 are brought into contact with the ends of the adjusting member 40 to prevent the adjusting member 40 from rotating carelessly. .
