Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an angle fixing device for a hinge structure member used for attaching a diagonal beam or a cut beam to reinforce a mountain retaining wall constructed around an underground structure of a building.

[0002]

2. Description of the Related Art In order to construct an underground structure of a building, FIG.
When digging down to the root cutting surface 34 like
Since the lateral pressure to be increased, the uprising 33 is attached as a horizontal reinforcing member, and the oblique beam 21 is installed between the beam 31a of the preceding floor structure 31 and the mountain retaining wall 32 is prevented from buckling into the inner space. There is an example of operating as follows. Further, when the erected state of the uprising 33 is viewed from the horizontal mounting surface, as shown in FIG. 8 or FIG. 9, the mountain retaining wall 32 is slanted by the oblique beam 21 or the cutting beam 22 and the firing 23 via the uprising 33. In some cases, it may be necessary to reinforce in the direction.

In this way, the slanted beam 21 (22) and the firing 23
Etc. are attached to the frame beam 31a or the uprising 33 at a unique angle corresponding to each erection position, so that as the joint 10 used for attachment, Japanese Patent Publication No. 3-466.
As shown in Japanese Patent Publication No. 10, a hinge structure member such as a free piece whose angle can be arbitrarily adjusted in the same plane is used. In addition, in the invention of Japanese Utility Model Laid-Open No. 52-32438, a hinge structure member (universal piece) that can adjust the angle three-dimensionally is proposed. If these are used, the joint can be changed depending on the mounting angle. It is rational and hassle-free since there is no need to manufacture or select pieces.

That is, in the hinge structure member disclosed in Japanese Utility Model Laid-Open No. 52324/1993 (referred to as a free piece in the present invention), the spherical pivot 11 is rotated by the lid 13 in the recessed portion of the spherical seat 12, as shown in FIG. The movable member is loosely fitted, and the female member 12 including the spherical seat and the male member 11 having the spherical pivot rotate three-dimensionally, whereby the relative angle can be freely changed. . Reference numeral 14 in FIG. 10 is a fastening bolt.

[0005]

However, since the hinge structure member (flexible piece) as described above needs to have strength as a joint for transmitting a load between the beams,
The total mass of the male and female members exceeds the limit that can be carried by human power, and it is naturally impossible to manually maintain the relative angle between the two members against the acting gravity. Therefore, when attaching the flexible piece to one beam, and even when attaching it to the other beam to form a joint, handling is often more difficult, and there is no concern about ensuring work safety. easy.

[0006]

The present invention is based on the following.
In order to solve the above-mentioned problems, a pair of mounting base ends facing each other of the above-mentioned universal piece whose angle can be adjusted three-dimensionally are connected by at least two turnbuckles, and It is possible to freely hold the angle of the hinge structure member. Two or more hinge structure members, each having a female member having a spherical seat and a male member having a spherical pivot that is rotatably fitted in the spherical seat, are provided on the mounting base end side of the piece. By connecting with the turnbuckle, it is possible to fix the relative positions of the male and female members. Further, in the present invention, it is also possible to use a hinge structure member which is formed by combining two rotating shafts whose rotating directions are limited to one plane while maintaining an orthogonal relationship with each other. Any turnbuckle mechanism that uses a member having a right-handed and left-handed joint can be used.

DETAILED DESCRIPTION OF THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 and FIG. 2 show an example in which the conventional free piece described above is incorporated in the apparatus as one component of the present invention. Therefore, the same members as those shown in FIG. 8 and subsequent figures are designated by the same reference numerals. First, FIG.
2 will be described in detail. A male member 11 having a spherical pivot is fitted into a concave portion of a female member 12 having a spherical seat formed on the inner side thereof.
After the mounting base ends 11a and 12a in 2 are bolted to arbitrary mounting members (in the illustrated example, the slab piece 15 having a triangular cross section and the box-shaped auxiliary piece 16) by bolts 14, Two turnbuckles 18 are stretched over the receiving and auxiliary pieces via the attached brackets 17 and 17a. The mounting bracket may be arranged directly on the base end sides of the male and female members.

Since the turnbuckle 18 is formed with joints of a right screw 18a and a left screw 18b at both ends, the length can be changed by twice the screw pitch for each rotation. Thus, the lengths of the two turnbuckles 18 can be arbitrarily adjusted, and thereby the relative angle between the male member 11 and the female member 12 can be freely fixed in three dimensions. The mounting holes 19 and 20 for mounting the brackets 17 and 17a for connecting with the turnbuckle 18 may be provided in a plurality of rows, so that both male and female members exceed the length adjustment range of the turnbuckle. It is possible to adjust the angle of. In the case of FIGS. 1-2, between the slab piece indicated by reference numeral 15 and the oblique beam (or cutting beam) material 21 (22) joined via the auxiliary piece indicated by reference numeral 16 of the present invention. It uses a device.

Next, another embodiment of the flexible piece will be described. This is the case shown in FIGS. 3 and 4, and in place of the combination of the female member 12 having the spherical seat and the male member 11 having the spherical pivot, the rotation direction is limited to one plane. This is an example in which a free piece 32, which is a combination of the rotating shafts 30 and 31 in an orthogonal relationship, is used as a constituent member. The reference numeral 30a is one mounting base end, and the same 31a is the other mounting base end. Since the other members are the same as those described above, description thereof will be omitted. However, since the same members are designated by the same reference numerals, it is described that it is sufficient to apply the above description with reference to the reference numerals.

Instead of the illustrated turnbuckle mechanism, it is also possible to use another type of screw-like fixing rod whose length can be adjusted and whose length does not change due to tension and compression. Even in this case, the effect of the present invention is the same. Further, it goes without saying that the universal piece according to the present invention can be generally used as a joint for a structure to be temporarily erected, not limited to oblique beams, sill beams, fire hammers, etc. for underground construction.

The cases shown in FIGS. 5 and 6 are similar to the above, and only the points different from the above embodiment will be described below. That is, the oblique beam or the beam member 2 is directly attached to the attachment base end side 11a of the male member 11 without an auxiliary piece.
It has been clarified that the turnbuckle mechanism 18c (18d) can be attached to the side surface and the lower surface side of both the male and female members, in addition to connecting 1 (22).

[0012]

As described above, according to the present invention, even if the installation angle of the diagonal member or the cross beam member attached to both ends of the pair of opposing base ends of the flexible piece varies, the respective angles are changed. Can be fixed to any position, and can be fixed in a stable shape in any posture.
It has the advantage of being safe, easy to carry, install, and remove. More specifically, FIG.
Since the conventional hinge structure member as shown in FIG. 1 is a hinge structure member, it can be freely moved in all directions. On the other hand, there is a risk during transportation and a risk during mounting. There was also a problem with sex, and another device or device for holding at a certain angle was needed. However, according to the present invention, it is possible to freely hold the above-mentioned angle by disposing the turnbuckle on the hinge structure member such as the above-mentioned free piece through the mounting bracket. It is extremely useful in practice as a kind of angle adjusting device.
