When suspending a suspension rod member such as a hanging bolt that suspends and supports a ceiling board or various components for electrical equipment, air conditioning, or disaster prevention from a floor plate called a The present invention relates to a mounting jig for a hanging rod member support fitting for a floor board plate, which allows a clamping spring type hanging rod member support fitting to be easily and quickly attached to a floor board plate.

[Technical background of the invention and its problems] Conventionally, a floor plate called an F-deck, which is made by bending a rolled steel plate of a predetermined thickness and providing a row of triangular reinforcing parts, has been used. When constructing a concrete floor in concrete building construction, suspension rod members such as hanging bolts are connected and suspended from the floor plate in order to suspend and support ceiling panels and various components for electrical equipment, air conditioning, and disaster prevention. It is said that For these reasons, in view of the need to improve the efficiency of work at extremely crowded construction sites, the load-bearing capacity of various suspended members, and other requirements, the applicant decided to We have proposed a clamping spring type suspension rod member support fitting that allows the suspension rod member to be suspended from a predetermined position. That is, as shown in FIG. 4, this hanging rod member supporting metal fitting F is attached to a reinforcing portion S having a substantially triangular cross section that is wide at the bottom and narrow at the top and protrudes downward at a predetermined floor plate P. In order to attach it, left and right standing leg pieces 105 are bent and erected on both ends of the bottom piece 102 located on the lower surface of the reinforcing part S, so as to face both side walls of the reinforcing part S, and are resiliently biased to close each other. These left and right standing leg pieces 105 are provided with a pressing pawl 106 that bites into both side wall surfaces of the reinforcing portion S, and an engaging portion 108 is provided at the tip.
A mounting member 101 formed with a
It has a female thread 111 into which the inner piece 10 is screwed.
2. It has a connecting member 110 that is fixed to the mounting member 101 in a downwardly protruding state, and has a groove-shaped cross section with reinforcing edges 121 standing upright on both side edges for reinforcement if necessary, Left and right side walls 124 are formed at both ends of the deep bottom wall 122 into a bent side groove shape, and the deep bottom wall 122 has a through hole 123 through which the connecting member 110 is inserted, and the left and right side walls 124 have a through hole 123 through which the connecting member 110 is inserted. The reinforcing members 120 each having an engaging hole 125 for engaging the engaging portion 108 are combined.

When using such a clamping spring type hanging rod member support fitting F, the mounting member 1 is used to improve load resistance.
It is advantageous for the left and right standing leg pieces 105 in 01 to have a strong elastic force that tends to close each other, in order to exert a strong clamping force on both side wall surfaces of the reinforcing part S. However, on the other hand, the reinforcement part S
It is troublesome that the left and right stand pieces 105 are difficult to expand when attached to the reinforcing part S, and therefore, it is sometimes necessary to attach it to the narrow part at the end of the reinforcing part S and then move it to a predetermined location. It has been found that the installation work is often dangerous, as it is often carried out at high places and facing upwards.

[Purpose of the invention] Therefore, this invention was devised to solve the above-mentioned difficulties by simply and quickly attaching a clamping spring type hanging rod member support fitting to a reinforced part of a floor plate. It can be installed extremely easily at any predetermined location of the reinforcement part, and,
The goal is to be able to do it safely and greatly improve work efficiency.

[Summary of the invention] In order to achieve the above-mentioned object, this invention uses swinging joints that protrude inwardly to urge the front part toward an elastic closing tendency. The present invention consists in that a pair of swingable handles that can be held are pivotally connected to each other so as to be swingable, and that an operating pin having an engaging recess at its tip is connected to the front portion of each swingable handle.

[Embodiment of the invention] Hereinafter, an embodiment of the invention will be described with reference to FIGS. 1 to 3.

Reference numeral 1 shown in the figure is a pair of left and right swinging handles that can be grasped with hands and fingers. They are pivotally connected to each other so as to be able to swing freely while being biased toward a repellent closing tendency.

The swing handle 1 itself is formed by bending a suitably thick sheet material into a U-shaped cross section that is open inward, and the front part thereof has strips extending facing each other. Swinging pivot parts 2 are pivotally connected to each other by inserting a shaft pin 3 between them, and by swinging the swinging handle 1, which is a gripping part, so as to close the rear parts of each other, the front parts can be expanded. It is starting to open. The swing handles 1 are connected to each other by a roughly dogleg-shaped spring 4 wound around a shaft pin 3, so that the rear part thereof is always biased to expand, thereby releasing the grip force from the hands and fingers. By doing so, it will automatically expand and restore. Note that when no gripping force is applied to the swing handle 1, the distance between the tips of the operating pins 10 is such that the left and right leg pieces 105 of the mounting member 101 in the suspension member support fitting F are opened. The through holes 107 are made to correspond approximately to each other, so that they can be easily inserted into the mounting member 101 and supported by engagement.

At that time, in order to restrict the swinging handle 1 to swing within a certain range, in particular, to prevent the swinging handle 1 from expanding more than necessary, a stopper notch 5 cut at the tip of one swinging pivot 2 is inserted into the other end. The stopper notch 5 is fitted into an engaging pin 6 horizontally suspended on the swinging pivot portion 2, and the inner edges of both ends of the stopper notch 5 collide with the engaging pin 6 when the swinging handle 1 is swung. .

And, at the front of each swinging handle 1,
An operating pin 10 having a notched engagement recess 11 at its tip is provided in series in order to engage with the edge of a through hole 107 formed in the left and right leg pieces 105 of the mounting member 101 of the hanging rod member support fitting F described above. ing. In the illustrated example, an operating pin 10 formed into a rod shape with an appropriate diameter is fitted and fixed in a mounting hole 9 formed in a mounting block 8 fixed with a rivet 7 in the front part of the swing handle 1. Although the operating pin 10 is connected to the swing handle 1, the operating pin 10 may be made into a strip shape, or the operating pin 1 may be connected to the swing handle 1.
It is optional to use a different structure for connecting the 0 to the swing handle 1.

In addition, the operating pins 10 are bent inward from each other in FIGS. 1 and 3. By doing so, the expansion force for the left and right leg pieces 105 of the mounting member 101 can be increased, and the expansion force can be increased. It is possible to easily position the mounting member 101 in the open state when bringing it to a predetermined position on the reinforcing portion S, thereby making it easy to attach and improving workability. Of course, the operating pin 10 may be linear as shown in FIG. 2.

Furthermore, as shown in FIG.
Since any one of the engaging recesses 11 engages with the through hole 107 formed in the opening 5, it is useful for improving handling and operability.

This device is constructed as described above, and when used, as shown in FIG. , insert the operation pin 10, engage the engagement recess 11, and then,
The operating pins 10 are spread apart by the force of gripping the swinging handle 1 with fingers, and thereby the left and right standing leg pieces 105 are spread apart. When the mounting member 101 in the expanded state is brought from below the predetermined position of the reinforcing portion S on the floor plate P, and the gripping force is released to remove the operating pin 10 from the left and right leg pieces 105, the mounting member 101 are attached to the reinforcing portion S by the resiliency of the left and right leg pieces 105 themselves that tend to close. Next, after incorporating the reinforcing member 120 if necessary, a predetermined hanging rod member B is screwed into the female thread 111 of the connecting member 110, and various predetermined members for ceiling panels, electrical equipment, air conditioning, and disaster prevention are attached to it (not shown). It is sufficient to suspend the

[Effect of the invention] Therefore, in order to attach the hanging rod member support fittings F to the reinforcement portion S of the floor plate P, the left and right standing leg pieces 105 of the mounting member 101 have elastic force in the closing tendency.
can be easily expanded, and the hanging rod member support fitting F can be attached to a predetermined position of the reinforcing part S with one touch, allowing work to be carried out safely and effortlessly even at high places.

That is, this invention makes a pair of swingable handles 1, which can be grasped, swing freely by biasing the front portions toward an elastic closing tendency through swinging pivot joints 2 that project inwardly from each other. An operation pin 10 which is pivotally connected to each other and has an engagement recess 11 at its tip is connected to a swing handle 1.
Since they are connected to each other in front, the clamping spring type hanging rod member support fitting F can be easily and quickly attached to the reinforcing portion S of the floor plate P.
The installation work can be carried out by firmly grasping the swing handle 1 with fingers and releasing it. In addition, when the left and right standing leg pieces 105 are expanded by grasping the swing handle 1, the hanging rod member support fitting F itself is supported by this invented mounting jig. This prevents the hanging rod member support fitting F from being lost or falling off even when carried upwards, allowing the installation work to be carried out quickly.In addition, the structure is simple and can be provided at low cost. This has extremely beneficial effects in practice.
