An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view showing a construction of a large pull according to the present invention, FIG. 2 is a partially exploded perspective view of the large pull, and FIG. FIG. 4 is a sectional view taken along line IV-IV in FIG.

[0010] A pull plate 1 of the present invention is a vertical flat plate bundle plate portion 2.
The flange portion 3 is joined and integrated at right angles to the surface direction of the bundle plate portion 2 so as to surround the entire peripheral edge of the bundle plate 2. The puller 1 is made of a metal such as iron, and has been subjected to a rustproofing treatment by an appropriate means such as plating.

The bundle plate portion 2 has an upper chord side 21 having a dimension slightly shorter than the distance between the opposing cloth foundations A and B, and both side sides 22, 22 slightly hanging from both ends of the upper chord side 21.
And a lower chord side 23 which is positioned parallel to the upper chord side 21 at a predetermined distance from the upper chord side 23.
24 are formed to have a substantially inverted hat shape in a front view. The cutout sides 24, 24 form cutouts 4, 4 at the lower ends of both ends of the large-sized pulley 1 such that a person can pass through. Therefore, the length of the lower chord side 23 is set to a length obtained by subtracting twice the width of the cloth base A and B from the distance between the cloth foundations A and B so that a person can pass. Specifically, it is set to be about 2 m shorter than the distance between the cloth foundations A and B. The lower chord side 23 is configured such that its longitudinal center coincides with the longitudinal center of the upper chord side 21 in the vertical direction. Thereby, when the pulling pulley 1 is installed between the cloth foundations A and B, the notches 4 and 4 having a width of about 1 m at which both sides can pass through are secured. These cutouts 4 and 4 are used for passage for maintenance and inspection under the floor at a later date.

The flange portion 3 is welded and fixed to the bundle plate portion 2 so as to surround the entire peripheral edge of the bundle plate portion 2, and the upper chord flange portion 31, both side flange portions 32, 32, respectively.
The lower chord flange portion 33 and the notch flange portion 34 are formed. Of these, flanges 3 on both sides
2, a plurality of fixing bolt insertion slots 35 for attaching fixing brackets 5 and 6, which will be described later, are formed at a plurality of locations. Further, the upper chord flange portion 31 is also provided with a through hole 36 for inserting a mounting tool for mounting the floor panel E and other members.

Next, a procedure for installing the pulling pulley 1 will be described.

First, both side flange portions 32 of the pulling pulley 1
Then, the fixtures 5 and 6 are temporarily fixed using bolts M and nuts N, respectively. Here, one fixture 5 is for the outer peripheral foundation A, and the other fixture 6 is for the partition foundation B. The difference between these fixing brackets 5 and 6 is that their legs 51 and 6
It has a length of 1 so that it can cope with a level difference between the top end surfaces of the outer peripheral foundation A and the partition foundation B. If the opposing cloth foundations are of the same type, only one of the fixing brackets 5, 6 may be attached to both ends of the fixing flange portions 32, 32. In the drawings, reference numerals 52 and 62 denote reinforcing webs, 53 and 63 denote hook pieces, respectively, and the anchor pieces 53 and 63 have anchor bolts planted on the top end faces of the cloth foundations A and B. An elongated hole (not shown) through which P is inserted is formed.

As described above, both side flange portions 32, 3
When the fixing fittings 5 and 6 are temporarily fixed to 2, the large pull-in 1 is carried into the cloth foundations A and B, and the locking pieces 53 and
The anchor bolts P of the cloth foundations A and B are inserted into the long holes of the 63, and the locking pieces 53 and 63 are hooked on the edges of the cloth foundations A and B, and the nut Q is fastened to the anchor bolt P and fixed. I do.

Further, the lower chord flange portion 33 is temporarily placed on the embankment surface C, and the bolt M, which has been temporarily fixed, is adjusted so that the upper surface of the upper chord flange portion 31 is at a predetermined level while adjusting the attitude of the entire pulling bar 1. Then, the nuts N are tightened to firmly fix the fixing brackets 5, 6, and the operation is completed.

[0017]

As described above, according to the present invention, it is possible to connect the flanges to the lower chord side by a simple operation such as connecting between the fabric foundations via the fixing members to the flanges connected to the both sides. The flange portion is set above the embankment surrounded by the cloth foundation, and the floor panel can be placed on the flange portion joined to the upper chord side, so that the slab stone and the bundle material can be omitted at all. Therefore, the number of components under the floor is small, and only a few people are required. Moreover, since the construction is much easier than before, it is possible to work easily and in a short time even for a non-expert. it can. This is very effective especially when it is required to complete the construction in a short time. In addition, since the slabs and the slabs are omitted at all, the floor does not fall due to aging.

Further, since notched sides are formed so as to allow a person to pass through from both ends of the lower chord side to the lower ends of both side sides, when installed between the cloth foundations, each person can sneak through the lower end of both ends. Space is secured. Therefore, this space can be used as a passage for maintenance, inspection and the like under the floor at a later date, and maintenance and inspection work can be facilitated.

Furthermore, since the puller of the present invention is made of metal in which the bundle plate and the flange are joined and integrated, the strength is high, and the floor of the first floor of the house can be firmly supported.

In addition, since mass production in a factory is possible,
It is possible to always produce a product having a constant quality, and it is possible to easily form a floor surface having excellent construction accuracy and quality.
