Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a suspension bracket used for suspending a suspension bolt or the like on a erection material such as a mold steel.

[0002]

2. Description of the Related Art Conventionally, in order to support a hanging bolt on a construction material such as a steel mold, a support metal fitting (registered trademark, Pirac) having a substantially U-shaped side surface, which the applicant of the present invention has previously proposed, has been used. The support fitting is configured such that the opening of the support fitting is attached to the construction material, and the support fitting is fixed to the construction material with a fastening bolt that is tightened from the upper end of the support fitting. The upper end of the suspension bolt is screwed with a fixing screw (see Japanese Utility Model Laid-Open No. 1-129408).

[0003]

However, the support metal fitting provided with such a connecting tool has the following problems. That is, since the connecting tool is mounted between the lower part of the support fitting and the building material, it is necessary to mount the connecting tool on the supporting fitting before mounting and fixing the supporting fitting to the building material. Therefore, the fixing of the support fitting is performed in a state where the connecting tool is placed on the lower part of the support fitting, so that the fixing work of the support fitting is troublesome.

In addition, the operation of connecting the suspension bolt to the connection fixture fixed to the support fitting is performed from below the building material to the connection fixture of the support fitting, and the further the work position is away from the construction material, the more the suspension bolt is connected. Connection work is difficult.

Therefore, the present invention was created in order to solve the above-mentioned problems, and a connecting tool can be retrofitted to a supporting metal fitting mounted on a construction material, which simplifies the mounting work and further, suspends. An object of the present invention is to provide a suspension support metal fitting that allows a connector to be attached to a support metal fitting together with a bolt.

[0006]

In order to achieve the above-mentioned object, according to the first means of the present invention, the upper plate 2 which is relatively opposed.
And the lower plate 3 are continuously formed via the side plate 4, and the upper and lower plates 2,
3, a predetermined construction material Q is sandwiched therebetween, and a fixing screw 6 for press-fitting the construction material Q is provided on the upper plate 2, while a support hole 7 through which the suspension bolt P is inserted passes through the lower plate 3. A suspension support fitting which is detachably attached to the support hole 7 and has a connecting tool 8 for connecting the ends of the suspension bolts P, wherein the support hole 7 is formed by a pair of plate-shaped superimposed upper ends of the connecting tool 8. A notch hole 7A for inserting the locking body 9 is formed, and the connecting tool 8 expands the ends of the pair of locking bodies 9 that are overlapped, and the upper end of the suspension bolt P screwed to the connecting tool 8 is locked. The support holes 7 are pressed and inserted between the bodies 9.
The locking member 9 is spread and locked at the upper part of the upper part.

The connecting means 8 of the second means is provided with a locking member 9 having a substantially T-shaped side surface at the overlapped end of one band-shaped plate, and a plate below the locking member 9. The screw body 10 for screwing the suspension bolt P is provided at the center of the body bending.

Further, in the connecting tool 8, one band-shaped plate body is bent, and a locking body 9 having a substantially T-shaped side surface is provided at the overlapped end, and the constricted part 9A of this locking body 9 is formed into a substantially arc. Providing the shape is the third means for solving the problem.

The connecting member 8 of the fourth means is formed by bending and expanding both ends of the overlapped strip in a front T-shape to form a locking member 9, while the connecting member 8 extends downward from the side plate 4 of the metal fitting body 1. This is because a long support hole 7 is drilled up to the plate 3, and an insertion hole 7 </ b> B for inserting the locking body 9 is connected to the support hole 7 of the side plate 4.

[0010]

According to the first and second means of the present invention, after the fitting main body 1 is mounted and fixed on the construction material Q, the connecting tool 8 is mounted on the support hole 7 of the fitting main body 1. At this time, the locking body 9 of the connecting member 8 is locked in the supporting hole 7 through the notch hole 7A of the supporting hole 7, and furthermore, a pair of locking members in which the ends of the suspension bolts P connected to the connecting member 8 overlap. The body 9 is expanded to fix the connector 8.

The third means is to connect the connecting tool 8 to the supporting hole 7 of the metal fitting body 1 swingably by the constricted portion 9A of the locking body 9 provided in a substantially arc shape. .

The connecting member 8 of the fourth means has a locking member 9 which is bent and expanded in a front T-shape, and is inserted into the supporting hole 7 of the lower plate 3 from the insertion hole 7B provided in the side plate 4 of the metal fitting body 1. Inductively locked.
