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 support fitting used for suspending a suspension bolt or the like on a erection material such as a shape steel.

[0002]

2. Description of the Related Art Heretofore, in order to support a suspension bolt on a building material such as a mold steel or the like, a side bracket having a substantially U-shape (registered trademark Pyrac) proposed by the present applicant has been used. The support fitting is configured such that an 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 an upper end of the support fitting, and the hanging bolt is a connecting tool attached to a lower portion 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] Furthermore, the present applicant has improved this support metal fitting so that a connecting metal fitting can be mounted later on the support metal fitting attached to the construction material (registered utility model No. 3008940). No. 3009202 and No. 3009440).

[0004] In a conventional suspension support fitting improved so that the connecting tool can be mounted later, the shape of the supporting hole for inserting and locking the connecting tool is changed into a keyhole shape or the like, and the supporting hole having this special shape is formed. The corresponding couplings and fixing nuts are used. As a result, it is possible to arbitrarily change the stable supporting strength and the supporting angle of the suspension bolt connected via the connecting tool.

[0005]

However, in the improved conventional suspension support fitting, the connecting tool is connected to the support hole formed in the lower part of the support fitting, so that the suspension position of the suspension bolt is just below the support fitting. Was limited to the vertical support position. For this reason, depending on the mounting state of the support bracket to the construction materials,
In some cases, such as when the support hole formed in the lower part of the support bracket is horizontal, the suspension bolt cannot be suspended.

[0006] Further, since a support hole having a special shape is formed, a connection fitting that can be connected to the suspension support fitting is limited to a fitting corresponding to the shape of the support hole. Therefore,
The problem that it was difficult to attach another versatile connecting fitting to the improved suspension support fitting of the related art was left.

[0007] Furthermore, the conventional suspension support bracket suspends the suspension bolt using a connecting tool or a fixing nut so that the support angle of the suspension bolt can be arbitrarily changed.
In order to connect the suspension bolts, many components such as these connecting tools and fixing nuts were required.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and is a suspension support fitting which can be retrofitted with a connecting fitting on a supporting fitting mounted on a building material. It is an object of the present invention to provide a suspension support fitting capable of suspending a suspension bolt in accordance with the mounting state of the above, and which can be used in combination with other versatile connection fittings.

[0011]

Embodiments of the present invention will be described below.

The hanging support fitting of the present invention comprises a fixture 1 for fixing to the building material Q, and a connector 10 attached to the fixture 1 and connecting the suspension bolt P to the fixture 1 (see FIG. 1). ).

The fixture 1 has an upper plate 2 and a lower plate 4 that are opposed to each other and are continuously formed with a side plate 3 interposed therebetween. A predetermined construction material Q is sandwiched between the upper and lower plates 2 and 4, and a fastening screw 6 for pressing the construction material Q is provided on the upper plate 2 (see FIG. 2).

On the other hand, the connecting member 10 is detachably attached to a connecting hole 5 penetrating through the side plate 3 and the lower plate 4 to suspend the suspension bolt P. Therefore, the connecting tool 10 is provided with a pair of locking projections 11 that are inserted into the connecting hole 5, expanded inside the connecting hole 5, and locked in the connecting hole 5. The locking projections 11 are formed by inserting a suspension bolt P screwed into a connecting piece 13 connecting the ends of the locking projections 11 between the locking projections 11.
The locking projection 11 is expanded inside the connection hole 5 (see FIGS. 1 and 2). At this time, a pair of extension pieces 12 extending from the respective locking projections 11 and a connection piece 13 for connecting the ends of the extension pieces 12 are integrally formed. The locking projection 11 in the illustrated example is connected to the connecting piece 13 via the extension piece 12.
Although the locking projection 11 may be provided directly from the connecting piece 13. Further, the locking projection 11 is extended from the end of the extension piece 12.
Is formed in a bent state, but is not limited to the illustrated example, and may be formed to extend linearly from the end of the extension piece 12 or the connection piece 13. Further, the locking projection 11 in the illustrated example includes a locking portion 11A that locks inside the connection hole 5 and an insertion portion 11B that inserts the connection hole 5, and the end of the insertion portion 11B (See FIG. 4).

The extension piece 12 includes a locking projection 11 and a connection piece 13.
And between. Then, a reinforcing bead 15 extending from the extension piece 12 to the locking projection 11 is provided (see FIG. 1). The reinforcing bead 15 increases the strength of the locking projection 11 and also serves as a position for confirming the insertion position of the suspension bolt P (see FIG. 2). That is, by inserting the tip of the suspension bolt P to a position where it comes into contact with the reinforcing bead 15, the locking projection 11 is sufficiently expanded, and the locking projection 11 is
Is securely locked. The extension piece 12 is bent at a connection portion with the connection piece 13. Then, the distance between the extension pieces 12 and the locking projections 11 that are continuous with the extension pieces 12 is set to be smaller than the diameter of the suspension bolt P so as to face each other (see FIGS. 1 and 2).

The connecting piece 13 connects the pair of locking projections 11 and has a screw hole 14 for screwing the suspension bolt P. Then, the suspension bolts P screwed into the screw holes 14 are inserted between the locking projections 11 so that the suspension bolts P and the fixture 1 are connected (see FIG. 1). Although the connection piece 13 in the illustrated example is tapped with a tap in order to screw the suspension bolt P, a screw hole 14 using a nut may be provided (not shown).

Since the present invention is configured as described above,
In use, after attaching the fixture 1 to an arbitrary construction material Q, the coupling tool 10 is attached to the coupling hole 5. At this time,
The pair of locking projections 11 of the connecting tool 10 are inserted into the connecting hole 5 in a state of being overlapped, and the locking projection 11 is temporarily locked inside the connecting hole 5 (see FIG. 4). Next, the suspension bolt P is screwed into the screw hole 14 of the connecting piece 13 and the suspension bolt P is inserted between the locking projections 11 until the tip of the suspension bolt P contacts the reinforcing bead 15 (see FIG. 2). . Then, the locking projection 11 is forcibly expanded in the connection hole 5, the locking projection 11 is securely locked in the connection hole 5, and the hanging bolt P is fixed to the fixture 1.
Suspended. Then, since the rotation of the locking projection 11 is enabled inside the connection hole 5, the suspension bolt P can swing freely within a range restricted by the shape of the side plate 3 of the fixture 1 (see FIG. 3). When the mounting state of the fixing tool 1 is different from the construction material Q, the connecting hole 5 is selected and the connecting tool 10 is mounted at a position corresponding to the situation (see FIG. 5).

[0018]

According to the present invention, as described above, according to the present invention, the connecting member 8 can be mounted later, corresponding to the mounting state of the support fitting 1 mounted on the building material Q.

That is, according to the first and second aspects, when the suspension bolt P is connected to the connecting tool 10 in a state where the suspension bolt P is inserted between the pair of locking projections 11, the locking projection 11 is connected to the fixing tool 1. The connector 8 is securely locked in the hole 5, so that the connecting device 8 can be mounted later without forming a specially shaped support hole as in the related art. As a result, the connection holes 5 formed in the side plate 3 and the lower plate 4 of the fixture 1 can be selected, and the suspension bolt can be suspended corresponding to the mounting state of the support bracket. In addition, since a support hole having a special shape is not formed, it is possible to use another versatile connection fitting together.

Further, according to the first aspect, the strength of the locking projections 11 is increased, and the expanded state of the locking projections 11 inside the connection hole 5 can be confirmed at the position of the reinforcing bead 15, so that the construction can be performed. Safety can be improved.

Further, since the suspension bolt P is swingably supported on the fixture 1, the suspension bolt P can be supported only by the member of the connector 10, so that the conventional suspension which requires many components such as the connector and the fixing nut is required. It is extremely easy to handle as compared with the hanging support.

Further, according to the second aspect, when the suspension bolt P is suspended, the suspension bolt P and the connecting member 10 are integrated, and excellent support strength is obtained.

As described above, according to the present invention, there is provided a hanging support fitting capable of attaching a connecting tool to a supporting fitting attached to a erection material at a later time, wherein a hanging bolt is provided in accordance with a mounting state of the supporting fitting. It can be suspended, is very easy to handle, and has various advantageous effects, such as being able to use other versatile connection fittings.
