2. Description of the Related Art Conventionally, on the lower surface of a rolled steel sheet having a predetermined thickness,
There is a floorboard plate which is commonly called an I-deck having a reinforcing portion having an I-shaped cross section and a floorboard plate which is also commonly called an L-deck having a reinforcing portion having an L-shaped cross section. It is used. The applicant has previously proposed a support fitting for suspending a suspension rod member such as a suspension bolt on the reinforcing portion of the I deck (see Japanese Utility Model Laid-Open No. 3-28306). This support bracket
A suspension bolt and the like are suspended and supported through a pair of gripping bodies that sandwich the side surfaces of the I-shaped reinforcing portion, a coupling body that is coupled under the gripping bodies, and a coupling nut that is fixed to the coupling body. is there.

The applicant of the present invention has also proposed a support fitting for suspending a suspension rod member on a plate for a floor board, which is generally called an F deck provided with a reinforcing portion having a triangular cross section (actual fair 2- 89
(See Japanese Patent No. 64). This support fitting is composed of a holding member having a notch-shaped holding port for fitting a reinforcing portion having a triangular cross section, and a hanging member connected under the holding member to suspend and support a hanging bolt or the like. I am configuring.

[0004]

However, in the support metal fitting for the I-deck, the connecting body for suspending the suspension bolt swings along the longitudinal direction of the reinforcing portion. However, there was an inconvenience that the tightening bolts for fixing the support fittings were loosened.

In addition, since the support metal fittings for the F deck are formed so that the supporting metal fittings are inclined so that they can be fitted to the side surfaces of the reinforcing portion having a triangular cross section, the support metal fittings of other types can be used. It was difficult to use it as a floor plate such as I deck or L deck.

Therefore, the present invention was devised in order to solve the above-mentioned problems, and can be used as a floorboard plate of a different type and can be mounted in an extremely stable state. An object of the present invention is to provide a support fitting for a rod member.

[0007]

In order to achieve the above-mentioned object, the present invention constitutes a support metal fitting to be attached to a reinforcing portion P1 having an L-shaped section and an I-shaped section which protrudes from the lower surface of a floorboard plate P. Then, a pair of sandwiching members 1 sandwiched between both sides of the reinforcing portion P1 and fixed with the tightening bolts 2 are provided. On the other hand, a hanging member 3 that is swingably connected under the sandwiching member 1 and that suspends the hanging rod member B is provided.

The sandwiching member 1 has a crimping side edge 4A which is crimped to the side surface of the reinforcing portion P1 and a notch shape into which a bending end portion P2 extending from the crimping side edge 4A and protruding from the lower end portion of the reinforcing portion P1 is inserted. And the insertion port 4B is formed.
Further, the crimping side edge 4A is provided with a press-contact piece 5 that press-contacts the plate surface of the reinforcing portion P1 as means for solving the problem.

Further, the sandwiching member 1 is bent and formed in a U-shape in plan view, and the sandwiching ports 4 formed in the opening portions can be opened and closed by connecting the opening portions facing each other. And the pinch 4
The second means is to insert the tightening bolts 2 for tightening the reinforcing member P1 into the opposing side surfaces of the sandwiching member 1 and to provide the reinforcing beads 6 on the side surfaces of the sandwiching member 1 provided with the sandwiching openings 4. And

Further, the suspension member 3 has a substantially U-shaped side surface, and a suspension hole for swingably supporting the suspension rod member 3 in a direction orthogonal to the direction in which the suspension member 3 swings. Opening 3B is the third means.

[0011]

According to the present invention, the clamping member 1 is fixed by the tightening force of the tightening bolt 2 with the crimping side edge 4A of the clamping opening 4 sandwiching the side surface of the reinforcing portion P1 of the floor plate P. In addition, the bending portion P2 of the reinforcing portion P1 having an L-shaped cross section or an I-shaped cross section is inserted into the insertion portion 4B of the holding port 4.

When the crimping side edge 4A crimps the reinforcing portion P1, the crimping piece 5 widely abuts and crimps on the plate surface of the floor plate P.

On the other hand, the reinforcing beads 6 prevent the holding member 1 from being deformed by the tightening force of the tightening bolt 2 or the load of the suspended object suspended on the holding member 1.

The suspending member 3 is connected to the sandwiching member 1 so as to swing perpendicularly to the longitudinal direction of the reinforcing portion P1 of the floor plate P, and the suspending member 3 is suspended. Holding hole 3
The suspension rod member 3 suspended from B is swingably supported in a direction orthogonal to the swing direction of the suspension member 3.

Embodiments of the present invention will be described in detail below with reference to the drawings. Reference symbol P shown in the drawing is a plate for a floor board called a deck plate. This floor plate P
Uses a projecting reinforcing portion P1 having an L-shaped section or an I-shaped section on its lower surface (see FIGS. 1 and 3). And
A pair of sandwiching members 1 sandwiched on both sides of the reinforcing portion P1.
And a suspending member 3 which is swingably connected to the sandwiching member 1.

The holding member 1 is fixed by a tightening bolt 2, and forms a holding port 4 for holding the reinforcing portion P1.
The sandwiching opening 4 has a crimping side edge 4A that is crimped to the side surface of the reinforcing portion P1 and a notch-shaped insertion that extends from the crimping side edge 4A and inserts a bent end portion P2 that extends from the lower end portion of the reinforcing portion P1. And part 4B. At this time, the sandwiching member 1 is formed by bending a plate body such as a steel plate into a U-shape in a plan view and connecting the openings to each other so that the sandwiching openings 4 formed in the openings can be opened and closed. Further, the crimping portion 4A is provided with a pressure contact piece 5 that presses against the plate surface of the reinforcing portion P1 (see FIG. 2). The pressing piece 5 in the illustrated example is bent and extended from the crimping portion 4A of the holding port 4 to the outside of the holding member 1, but the shape and connecting means of the pressing piece 5 are not limited to the illustrated example.

The tightening bolts 2 are inserted into the opposite side surfaces of the sandwiching member 1. Then, a reinforcing bead 6 is provided on the side surface of the sandwiching member 1 provided with the sandwiching port 4. Reinforcement bead 6 shown
