DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden floor structure.

[0002]

2. Description of the Related Art Conventionally, a cloth foundation 1 constructed of concrete or the like, a base 2 laid on the cloth foundation 1 and fixed with anchor bolts or the like, and a height dimension larger than the height dimension of the foundation (for example, 2 FIG.
The bases 2, 2
A plurality of pulleys 3 laid between them as shown in FIG.
6 to 8 in which a floor plate (not shown) is laid directly or via a joist (not shown) on each of the girders 3.
2. Description of the Related Art A floor structure of a wooden building as shown in FIG.

The base 2 has a large-hanging hooking portion. A straight-working hooking-end fitting groove 4 into which a large-end 3 end is fitted, and a small-end end of the large-drawing 3 are provided. The part 6 is formed by a small groove 5 inserted and engaged from above, and the end of the large pulley 3 hanging on the base 2 is supported by inserting a notch 7 as shown in FIG. As shown in FIG. 8, the support is supported by the cloth foundation 1 (the vertical load applied to the large pulley 3 is supported by the bottom surface of the notch 7) or the large support fitting 8 attached to the base 2. Has become.

[0004]

In the above-mentioned conventional floor structure, the floor is lowered due to the thinning of the girders 3 caused by the drying of the wood, etc. In this case, to correct the problem, an operator goes under the floor and lifts the large pulley 3 with a jack or the like.
Alternatively, padding such as packing must be inserted into the support portions at both ends with respect to the large receiving fitting 8 to correct the descent, so that there is a problem that workability is extremely poor and it takes time to correct the descent.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the invention is to improve the workability of adjusting the pulling up and down of the floor set of the first floor, and to easily lower the floor due to the thinning of the pulling out. Another object of the present invention is to provide a wooden building floor structure that can be quickly modified.

[0006]

In order to achieve the above object, according to the present invention, a cloth base 1 and a base 2 fixed on the cloth base and a height H larger than the height h of the base are set. In a wooden building floor frame structure comprising: a large pulley 3 having both ends lifted and movably engaged with the base 2 and suspended between the bases, both side positions sandwiching the large pulling end of the base 2 A pair of left and right base fixing brackets 11 and 12 are provided on the left and right base fixing brackets, and a large undertaking member 13 for supporting the lower end portions of both ends of the large puller 3 is suspended on the left and right base fixing brackets via a pair of hanging bolts 14 and 15. By turning the nut screwed into the threaded portion of the two bolts to move the large receiving member 13 upward or downward, the raising and lowering of the large pulling member 3 supported by the receiving member 13 can be adjusted. It is characterized by the following.

It is desirable that the bolts 14 and 15 are all screw bolts having a length capable of fastening the base fixing brackets 11 and 12 and the large undertaking member 13. In this case,
The upper nuts 14b, 15b for tightening the bolts to the base fixtures 11, 12 and the lower nut 14 for tightening the large undertaking member to the bolts 14, 15 are attached to the thread portions of the full screw bolts.
a and 15a.

By doing so, the lower nuts 14a, 15
a to rotate the large undertaking member 13 upward or downward, as well as to rotate the large nuts 14b, 15
By turning b, the large undertaking member 13 can be moved upward or downward, and the raising and lowering adjustment of the large undertaking 3 can be performed with good workability.
