Description

[Detailed description of the invention] This invention relates to a support fitting for hanging rod members, and is used to attach ceiling plates and electrical equipment to a floor plate called F-deck, which is used when constructing concrete floors in concrete building construction work.・A suspension rod that is used to suspend suspension members such as hanging bolts that suspend and support various components for air conditioning and disaster prevention, and can be mounted and supported from below at any position after the floor plate is constructed. This invention relates to a member support fitting.

Conventionally, as shown in Fig. 6, concrete is constructed using a floor plate P called an F-deck, which is formed by bending a rolled steel plate of a predetermined thickness and having triangular reinforcing parts S arranged in a row. When constructing a concrete floor base C in building construction, ceiling panels, electrical equipment, etc.
In order to suspend suspension rod members B such as hanging bolts that suspend and support various members L for air conditioning and disaster prevention, insert tools I are temporarily fixed in advance from above after tensioning the floor plate P. After concrete is poured and constructed, the floor plate P is connected to the insert tool I from below by a predetermined means. However, according to this, it is necessary to drill a mounting hole in the floor plate P for fixing the insert tool I, and it is also necessary to securely fix the insert tool I so that it can sufficiently withstand the impact and vibration of the concrete material being poured. Moreover, the work at the extremely crowded construction site was inefficient.

For this reason, the inventors of the present invention focused on the use of the reinforcing portion S that is arranged to protrude below the floor plate P after construction.
No. 46439 Utility Model Publication No. 152003 (March 1988)
30th application), F deck floor plate P
We have proposed a support fitting for hanging rod members that can be used exclusively for this purpose. This is done by pivoting a pair of left and right clamping members so that they can be opened and closed so as to sandwich the reinforcing part S of the floor plate P, and suspending the hanging rod member B from the suspension member pivoted on the pivoted parts. It was designed to do so.

However, according to this method, since the hanging members are provided at the mutually pivoted parts of the clamping members, it is necessary to assemble the hanging members at the same time as clamping and fitting them to the reinforcing part S, which is troublesome and complicated. Ta. Furthermore, since there is only one hanging member itself, it is not only difficult to suspend multiple hanging rod members B, but also requires suspending multiple hanging rod members B depending on the site situation. in case of,
I couldn't deal with this easily.

Therefore, the inventors of the present invention have made improvements from various viewpoints in order to solve the conventional drawbacks as described above, and have developed a combination of a pair of clamping members that can be freely opened and closed in a mutually attached state. Separately, a hanging member can be attached to the clamping member, and moreover, by attaching a plurality of hanging members, it is also possible to suspend two hanging rod members.

This invention will be explained below with reference to FIGS. 1 to 5.

That is, one embodiment of the present invention is a support fitting that is attached to a reinforcing part S having a substantially triangular cross-section, which is wide at the bottom and narrow at the top, and protrudes downward in a predetermined floor plate P. A pair of left and right holding members 1 consisting of a front plate 1a, a side plate 1c, and a back plate 1b are formed by bending a sheet material into a substantially U-shaped planar shape, and the openings of these holding members 1 are made to face each other. The front plate 1a and the back plate 1b are partially overlapped, and the clamping members 1 are pivoted to each other so that they can be opened and closed from side to side, and the clamping member 1 is closed and swung between the side plates 1c of the clamping member 1. The bolt 11 is inserted through and the nut 12 is fixed, and the reinforcing portion S is provided on the side edges of the opening of the front plate 1a and the rear plate 1b of the holding member 1.
A hanging member having a substantially groove-shaped cross section, in which a clamping opening 2 is formed with a notch and has a diagonal edge 3 that abuts on the left and right outer surfaces and a horizontal edge 4 that abuts on the bottom outer surface, and a predetermined hanging rod member B is screwed thereto. 14, the front plate 1a and the back plate 1b of the clamping member 1 at different parts from the mutually pivoting parts of the clamping members.
They are connected to each other so that they can swing freely.

Therefore, the holding member 1 is made by bending a suitably thick approximately strip-shaped sheet material into a U-shape in plan view, and cutting it into a V-shape from the upper side of the opening side edge of the front plate 1a and the back plate 1b. The opening 2 is formed, and the front plate 1
a, holding member 1 at the bottom of the opening of the back plate 1b;
A through hole 5 is bored through which a shaft pin 6 for mutually pivoting is inserted. The size of the notch in the clamping opening 2 is sufficient to allow the clamping opening 2 to securely fit and clamp onto the reinforcing part S when the pair of clamping members 1, which are pivotally attached so as to be openable and closable, are sufficiently closed. It is a thing.

The holding members 1 are pivotally connected to each other by a shaft pin 6 such as a bolt, and at this time, the shaft pin 6 is prevented from coming off by caulking, or if it is a bolt, it is screwed with a nut. It is done by

In the illustrated example, spacer means 7,
It is equipped with 8 and 9. The spacer means 7 shown in FIG. 1 is arranged so that one clamping member 1 is sandwiched between the front plate 1a and the rear plate 1b of the other, and the spacer means 7 is arranged so that one clamping member 1 is sandwiched between the front plate 1a and the rear plate 1b of the other. It is made up of left and right protrusions that are butted against each other,
The spacer means 9 shown in FIG. 5 is arranged so that the clamping members 1 engage with each other when viewed from above, and the tip of the front plate 1a disposed inside one clamping member 1 is connected to the other clamping member 1. The tip of the back plate 1a arranged inside the other clamping member 1 abuts against the inner surface of the back plate 1b arranged inside the other clamping member 1. The spacer means 8 shown in FIG. 4 is a ring fitted onto the shaft pin 6. Of course, if the clamping member 1 has sufficient strength not to be distorted even when tightened by the shaft pin 6, the spacer means 7, 8, and 9 can be omitted.

Tightening bolts 11 for pivoting the clamping members 1 to close and swing each other are attached to side plates 1c of each clamping member 1.
It is inserted into the insertion hole 10 drilled in the hole 10, and after being placed in the reinforcing part S, when closing the reinforcing part S so that it is clamped and externally fitted, the insertion position of the tightening bolt 11 is adjusted in the vertical direction. Therefore, the shape of the insertion hole 10 is made into a long hole shape along the vertical direction. This tightening bolt 11 closes the clamping members 1 together by a nut 12 that is screwed into the clamping bolt 11. At this time, in order to prevent the clamping bolt 11 from idling, a hole is opened in the side plate 1c of the clamping member 1. A hole edge of a certain insertion hole 10,
As shown in FIG. 3, for example, it is preferable to form a square root portion 13 at the base end of the shaft rod having contact surfaces that contact the left and right edges of the hole to facilitate the work of securing the nut 12. By employing such a square root portion 13, it is possible to not only ensure the prevention of idling, but also to facilitate handling and to simplify the structure.

Further, the hanging member 14 has a front plate 1a, a back plate 1b of the clamping member 1 on both sides of a bottom piece 14a, which has a female screw hole 15 of a predetermined diameter to which a hanging rod member B such as a hanging bolt is screwed. A suspension hole 16 into which a suspension pin 18 is inserted in order to be swingably connected to the
The left and right side pieces 14b are perforated and arranged vertically to face each other, and are formed into a U-shape or a rectangular U-shape with a substantially groove-shaped cross section. That is, the front plate 1a of the holding member 1,
The suspension holes 16 are made to correspond to the through holes 17 drilled in the side plate 1c at the lower part of the back plate 1b, particularly below the insertion portions of the tightening bolts 11, and the suspension pins 18, such as bolts, are inserted through the holes 17. It is inserted into the suspension hole 16 and screwed using either a separately prepared nut or a tap hole. The female threaded hole 15 shown in the figure is formed in a cylindrical portion formed by protruding the bottom piece 14a portion outward in a stamped manner, and is designed to ensure reliable screw connection with the hanging rod member B. be. Note that this hanging member 14
may be installed on each of the holding members 1 or only on one of the holding members 1, and may be appropriately selected depending on the usage situation at the site and other factors.

Next, to explain the use of this with reference to FIG. 2 and a third example, in a concrete floor plate C constructed through a prescribed construction method, reinforcement of the floor plate P called the F deck. At a predetermined position in section S, the open clamping member 1 is brought from below, and the clamping members 1 are pivoted to close each other by screwing the nut 12 onto the tightening bolt 11, and the clamping opening 2 is closed.
Attachment is completed by sandwiching and fitting the reinforcing portion S at the step. Next, the suspension member B is suspended from the suspension member 14 connected to the holding member 1, and various members L such as lighting equipment are attached and supported via the suspension member B.

Therefore, unlike in the past, the hanging rod member B can be suspended at a required predetermined position after the construction of the concrete floor board C is completed, and there is no need to drill holes in the floor board plate P in advance. This eliminates the need for wiring for electric drills, so they do not interfere with each other's work at busy construction sites, greatly improving work efficiency. is also possible.

The pair of left and right holding members 1 are bent into a substantially U-shape when viewed from the front plate 1a, side plate 1c, and rear plate 1b, so that the tightening bolts 11 inserted between the side plates 1c are Even when the nut 12 is fastened, the reinforcing part S is securely and externally fitted through the clamping opening 2 without being distorted due to its strong tightening force. In addition, the front plate 1a and the back plate 1b are partially overlapped with the openings of the clamping member 1 facing each other, and the clamping members 1 are pivoted so that they can be freely opened and closed from side to side, and the front plate of the clamping member 1 is 1a, the clamping opening 2 is cut out at the side edge of the opening of the back plate 1b.
A total of four edges from both sides of the reinforcing part S are compressed by the strong tightening action obtained by the tightening bolts 11 and nuts 12, making the installation more stable. be.

The clamping openings 2 cut out in the side edges of the openings of the front plate 1a and the rear plate 1b of the clamping member 1 have a cross section in which the bottom of the floorboard plate P is wide and the top is narrow, protruding downward. Since it has a diagonal edge 3 that abuts on the left and right outer surfaces of the substantially triangular reinforcing section S and a horizontal edge 4 that abuts on the bottom outer surface, it is firmly and pinch-fitted to the outer side of the reinforcing section S, and the hanging rod member B, It does not come off even under the load of various members L applied through the hanging member 14, and there are no clamping holes 2 on the slopes of the left and right outer surfaces of the reinforcing part S.
By bringing the beveled edges 3 into close contact with each other, more stable supporting force can be obtained.

The hanging member 14 has a substantially groove-shaped cross section, and is swingably connected between the front plate 1a and the back plate 1b at a portion different from the pivoting portion of the clamping member 1.
The hanging member 14 can be attached to the clamping member 1 completely separately from the operations such as assembling the pair of clamping members 1 so that they can be opened and closed, and clamping and fitting them to the reinforcing part S. It can accommodate both vertical and inclined states with respect to L, and by providing a total of one pair for each clamping member 1, it is possible to suspend two suspension members B, and furthermore, the number of suspension members B can be changed. Since it can also be used freely, it is possible to achieve versatility in usage patterns in the field.
Moreover, the hanging member 14 itself can be easily connected to 1, and furthermore, the hanging rod member B can be suspended and connected by simply screwing in, so handling is easy and a large amount of work is required. This has extremely beneficial effects in practice, such as being able to withstand heavy loads.
