BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a hanging rod member support fitting for suspending a hanging member such as a hanging bolt on a floor plate called an F deck.

[0002]

2. Description of the Related Art Conventionally, as a support fitting for connecting a suspension bolt to an F deck, a suspension rod member support fitting previously registered by the applicant (utility model registration No. 1842114) has already been used in many sites. Proven effectiveness.

This suspension rod member support fitting utilizes a reinforcing portion projecting downward of the F deck and having a substantially triangular cross section.
A pair of left and right sandwiching portions that sandwich the reinforcing portion are formed, and a suspension member that connects suspension bolts and the like is provided below the sandwiching portion.

[0004]

In the conventional support metal fitting, a pair of left and right holding portions and a suspension member for connecting the suspension bolts are separately formed, and the suspension bolts are connected to the connection bolts penetrating the holding portion. It is configured to be screwed so that it can swing.

Then, in the supporting metal fittings mounted on the F deck,
When connecting the hanging bolts afterwards, there are cases in which the length of the hanging bolt is used to aim the tip of the hanging bolt on the suspension portion and operate from below. However, since the suspension portion swings in the conventional support fitting, the position thereof is difficult to be determined, and there is a problem that a lot of labor is required for connecting the hanging bolts to be attached later, which is operated from below.

Further, since the supporting metal fittings are used in large quantities in many sites, there has been a demand for a structure which can further rationalize the workability of manufacturing, transportation and management.

Therefore, the present invention has been devised to solve the above-mentioned problems, and it is possible to improve the conventional hanging rod member supporting metal fittings and further simplify the mounting work.
It is an object of the present invention to provide a hanging rod member support fitting that can streamline the workability of manufacturing, transportation, and management.

[0008]

In order to achieve the above-mentioned object, the first means of the present invention is a hanging rod member support fitting to be attached to a reinforcing portion P1 having a substantially triangular cross section which projects downward from a floor plate P. And a pair of left and right sandwiching pieces 1 for sandwiching the side surface of the reinforcing portion P1, and a tightening bolt 3 for screwing the sandwiching piece 1 to fix the sandwiching piece 1 to the reinforcing portion. This is because the end portion of the sandwiching piece 1 is extended below the reinforcing portion P1 to form the suspension portion 2 for suspending suspension members such as the suspension bolt Q.

Further, the suspension part 2 of the second means is integrally provided with a female screw part 2A for screwing the tip of the suspension bolt Q.

The suspension means 2 of the third means is provided with a notch locking hole 2B into which the tip of the suspension bolt Q to which the nut R is screwed is inserted from the side surface.

[0011]

In other words, according to the present invention, the suspension portion 2 extended from the lower end portion of one of the holding pieces 1 also fixes the position of the suspension portion 2 itself when the holding piece 1 is fixed to the reinforcing portion P1. It

A female screw portion 2A formed on the suspension portion 2
The hanging bolt Q is screwed by the operation from below.

Further, a notch locking hole 2B formed in the suspension portion 2
Is for locking the tip of the suspension bolt Q to which the nut R is screwed.

[0014]

Embodiments of the present invention will be described in detail below with reference to the drawings.

The supporting metal fitting of the present invention comprises a pair of left and right holding pieces 1.
And a tightening bolt 3 for tightening and fixing the sandwiching piece 1, and a suspension portion 2 for suspending the suspension bolt Q and the like (see FIG. 1).

The sandwiching piece 1 is connected to a floor plate P called an F deck, and is sandwiched by a reinforcing portion P1 which has a substantially triangular cross section and projects downward from the floor plate P. for that reason,
The opening when the sandwiching pieces 1 are combined with each other is formed in a substantially triangular shape along the outer periphery of the reinforcing portion P1, and the sandwiching pieces 1 are overlapped under the reinforcing portion P1. Then, they are swingably connected by a shaft pin that passes through the overlapped sandwiching pieces 1 (see FIG. 3). The illustrated sandwiching piece 1 is formed by a plate body that is bent into a substantially U-shaped cross section (see FIG. 1).

The suspension part 2 is formed so as to extend from the lower end of one of the sandwiching pieces 1. When the supporting metal fitting of this invention is mounted,
It is located below the reinforcing portion P1 and suspends a suspension member such as a suspension bolt Q (see FIG. 2).

At this time, the suspension portion 2 shown in FIGS.
A tap-shaped female screw portion 2A for screwing the tip of the hanging bolt Q is integrally provided, and the tip of the hanging bolt Q is screwed to the female screw portion 2A. Further, the female screw portion 2A shown in FIG. 5 has a through hole 2C formed at the bottom of the suspension portion 2 through which the suspension bolt Q penetrates, and a nut 2E is welded to the through hole 2C to form the female screw portion 2A. It is a thing.

The suspension portion 2 shown in FIG. 4 is provided with a notch locking hole 2B into which the tip of the suspension bolt Q to which the nut R is screwed is inserted from the side surface. Then, the nut R at the tip of the hanging bolt Q is locked and connected to the notch locking hole 2B.

Further, the suspension portion 2 shown in FIG. 5 has a reinforcing piece 2D which is continuous with the sandwiching piece 1 and the suspension portion 2 in order to increase the strength of one of the sandwiching pieces 1 forming the suspension portion 2. Is provided.

The tightening bolts 3 are tightened after the openings of the holding pieces 1 are fitted to the reinforcing portion P1 and then the holding pieces 1 are tightened.
Fixed to 1. The tightening bolt 3 shown in the drawing has an insertion hole 1A formed in each of the opposing side surfaces forming the thickness of each sandwiching piece 1,
The tightening bolt 3 is inserted into the insertion hole 1A. The opening / closing of the sandwiching piece 1 is adjusted at the tightening position of the nut 4 (see FIG. 1).

[0022]

The present invention achieves the original purpose by being configured as described above.

That is, according to claim 1, when the sandwiching piece 1 is fixed to the reinforcing portion P1 of the floor plate P, the position of the suspension portion 2 itself is also fixed. As a result, the workability of connecting the suspension member to the suspension portion 2 by the operation from below is improved.

Further, according to the second aspect, since the suspension member can be connected only by screwing the suspension bolt Q into the female screw portion 2A of the suspension portion 2, the operation from below the suspension bolt Q becomes easy.

Further, according to the third aspect, since the suspension bolt Q is locked and coupled from the notch locking hole 2B on the side surface of the suspension portion 2, the work of connecting the suspension member can be further simplified.

Moreover, since the one holding piece 1 and the suspension portion 2 are integrally formed, the number of parts is smaller than that of the conventional support fitting, and the workability of manufacturing, transportation and management is rationalized. Was successful.

As described above, according to the present invention, various practically useful effects can be obtained such that the mounting work can be further simplified and the workability of manufacturing, transportation and management can be rationalized.
