Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) This invention is a floor plate having an I-shaped projection formed on the lower surface of the plate (hereinafter referred to as I-type deck plate).
Further, the present invention relates to a hanging rod member support fitting suitable for supporting a hanging rod member such as a hanging bolt for hanging a lighting fixture, a pipe, a cable rack, or the like.

(Prior art) With the spread of high-rise buildings, in order to shorten the construction period at the time of slab molding, there is a construction method that uses a floor plate called deck plate that does not require the removal of the formwork.
It is widely adopted.

This deck plate is one in which concrete is placed on a metal plate having a corrugated cross section.To dispose a suspension rod member for suspending lighting equipment under the deck plate, concrete It was necessary to preliminarily open a hole for supporting metal fittings in the deck plate before the mounting of and to attach a supporting metal for supporting the hanging rod member to this hole (see FIG. 8).

Therefore, in the past, a special tool for opening the deck plate (see Japanese Utility Model Publication No. Sho 59-104934) and supporting metal fittings such as floor plate inserts to be mounted before placing concrete (Actual Utility Model Sho 60-29805). No.) was used.

Recently, an I-type deck plate has been attracting attention as a floor plate plate that replaces the deck plate. This I-shaped deck plate has an I-shaped protrusion formed on the lower surface of the deck plate in order to make the upper surface of the deck plate flat. Compared to conventional deck plates with a corrugated cross section, the amount of concrete used It has the advantage that it requires less and that it has higher support strength than conventional deck plates.

(Problems to be solved by the invention) However, in order to attach inserts etc. to the former deck plate before placing concrete, while checking the attachment position of the suspension rod member on the lower surface of the plate in advance, opening work on the upper surface of the plate It is necessary to carry out insert mounting work, and there is a disadvantage that various mounting work for mounting the suspension rod member cannot be carried out for such troublesome work removal.

Moreover, since the mounting position of the hanging rod member must be determined before placing concrete, if the mounting position is changed after mounting the hanging rod member,
Dealing with this change has become extremely difficult.

Therefore, the present invention was devised to solve the above-mentioned problems, and in construction using an I-type deck plate for the floor plate, it can be installed at any time regardless of the concrete pouring time, and furthermore, it can be installed. It is an object of the present invention to provide a supporting member for a hanging rod member, which is easy to work and can very easily cope with a change in position after mounting the hanging rod member.

(Means for Solving the Problems) In order to solve the above problems, the first means of the present invention is to suspend a hanging bolt or the like on a floor plate P having an I-shaped protrusion P1 formed on the lower surface of the plate.

A pair of gripping pieces 1 for gripping both width-width ends of P2, and a fastening hole 3 extending downward from the gripping piece 1 into a substantially U-shape and having the lower end of the holding piece 3 inserted through the hanging rod member Q are formed. The lower portion of the connecting body 2 includes a mounting portion 4 on which a connecting nut 10 for screwing the suspension rod member Q is mounted on the upper surface of the opening of the fastening hole 3.
Locking portions 5 for preventing rotation of the connecting nut 10 are provided on both sides of the mounting portion 4 relative to each other, and the tightening bolt 20 for tightening the pair of gripping pieces 1 is laterally provided on the upper portion of the connecting body 2. This is because the tightening hole 6 which can be inserted is opened.

Further, as a second means of the present invention, the connecting body 2 has a pair of locking holes 7 for locking the opposite corners on the outside of the connecting nut 10 formed in the locking portion 5 for solving the problem. And the means.

(Operation) That is, according to the first means of the present invention, the pair of gripping pieces 1 grips both end portions in width and length of the reinforcing piece P2, and the gripping piece 1
A connecting body 2 extending downward in a substantially U-shape from above to detachably supports a hanging rod member Q such as a hanging bolt.

The suspension rod member Q passes through the fastening hole 3 in the lower part of the connecting body 2, and the connecting nut 10 placed on the placing portion 4 on the upper surface of the opening of the fastening hole 3.
It is screwed to. Due to the tightening of the upper portion of the connecting body 2, the connecting nut 10 has its outer surface locked to the locking portion 5 when screwed, and the rotation of the connecting nut 10 itself is prevented.

The pair of gripping pieces 1 gripping both widthwise ends of the reinforcing piece P2,
By tightening the tightening bolt 20 which is inserted in the lateral direction into the tightening hole 6 of the coupling body upper portion 2, it is fixed to the reinforcing piece P2.

Further, according to the second means, the connecting nut 10 sandwiched between the locking portions 5 is locked in the pair of locking holes 7 formed in the locking portions 5 at the corners on the outer sides thereof. And then fixed.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

Reference symbol P shown in the drawing is a floor plate, and the floor plate P has a flat upper surface of a deck plate and a plurality of I-shaped protrusions P1 formed in parallel on the lower surface of the plate. is there. The I-shaped protrusion P1 is provided with a reinforcing piece P2 that extends from the lower end of the protrusion P1 to both sides of the longitudinal section of the protrusion P1 and extends along the longitudinal direction of the protrusion P1 (second). See figure).

Reference numeral 1 is a gripping piece, and a pair of gripping pieces is formed so as to grip both end portions of the reinforcing piece P2 of the protrusion P1 in the width direction from both sides. This gripping piece 1 is formed by bending both ends of the strip-shaped material, and a connecting body 2 described later is formed in the central portion of the strip-shaped material extended from both gripping pieces 1.

The connecting body 2 extends downward from the gripping piece 1 in a substantially U-shape, and has a fastening hole 3 at its lower end through which a hanging rod member Q such as a hanging bolt is inserted (see FIG. 1). ).

And, in the lower part of the connecting body 2 in which the fastening hole 3 is formed,
A mounting portion 4 on which the connecting nut 10 for screwing the suspension rod member Q is placed and a locking portion 5 for locking the side surface of the connecting nut 10 are provided.

The mounting portion 4 is formed on the peripheral edge of the opening of the fastening hole 3, and is formed by bending the central portion of the belt-shaped material to form a surface on which the connecting nut 10 can be mounted. At this time, the fastening hole 3 through which the hanging rod member Q is inserted is formed in a burring shape for screwing the hanging rod member Q in addition to forming the fastening hole 3 having a diameter slightly larger than the diameter of the hanging rod member Q. Is also good (see FIG. 6).

The locking portion 5 is formed by bending so as to face each other on both sides of the mounting portion 4, and the side surface of the connecting nut 10 is locked and fixed between the locking portions 5 (see FIG. 2). At this time, the distance between the locking portions 5 is formed so that the connecting nut 10 is loosely fitted, and
A bead 8 is formed in a continuous portion of the mounting portion 4 and the locking portion 5,
It is also possible for the inner side surface of the locking portion 5 inclined to the inside of the connecting body 2 to forcibly tighten the outer upper end portion of the connecting nut 10 (see FIG. 7).

On the other hand, an upper portion of the connecting body 2 is provided with a tightening hole 6 for laterally inserting a tightening bolt 20 for tightening the pair of grip pieces 1 (see FIG. 2). In the illustrated example, a square root bolt is used as the tightening bolt 20, and the tightening hole 6 matching the square root bolt is opened. That is, the tightening holes 6 on the inserting side of the tightening bolts 20 are formed in a square hole shape, and the tightening holes 6 on the fixing side of the nut 21 are round holes (see FIG. 1). The shape of these tightening holes 6 can be arbitrarily set depending on the type of tightening bolt 20 to be used and the presence or absence of a nut 21. For example, the shape of the tightening hole 6 on the side where the tightening bolt 20 is inserted may be the round hole shape or the gourd hole shape described in FIGS. 4 (I) and (II). Further, as the tightening hole 6 on the protruding side of the tightening bolt 20 on the opposite side, any setting such as a burring shape or a tap screw shape described in FIGS. 5 (I) and (II) can be made.

Reference numeral 7 is a locking hole. This locking hole 7 is used for the connection nut 1.
The outer corners of the connecting body 2 which are opposed to each other are locked and are opened in the locking portion 5 of the connecting body 2 (see FIG. 3). At this time, the locking hole 7 is formed so that it can be sufficiently temporarily fixed by the facing position of the locking portion 5 even before the metal fitting of the present invention is attached to the reinforcing piece P2 and tightened.

(Effect of the Invention) The present invention achieves the original purpose by being configured as described above.

That is, according to claim 1, in the construction using the floorboard plate P in which the I-shaped protrusion P1 is formed on the lower surface of the plate, the suspension rod member Q such as a suspension bolt is suspended regardless of the concrete pouring time. It can be detachably supported on the lower surface of the rod member Q.

Therefore, like the conventional construction using the deck plate, it is freed from the troublesome work such as the installation work of the insert before the concrete is placed.

Moreover, the reinforcing piece P is formed by projecting from the lower end of the I-shaped projection P1 on both sides of the longitudinal section of the ridge and extending along the longitudinal direction of the ridge.
Since the support metal fittings themselves are attached by the pair of gripping pieces 1 for gripping both width-length ends, after placing concrete,
Even if the mounting position of the hanging rod member is changed, the mounting position of the support fitting itself can be changed very easily.

Further, according to claim 2, the connecting nut 10 placed on the placing portion 4 of the connecting body 2 has a pair of locking holes 7 formed in the locking portion 5.
Further, since the opposite corners on the outside thereof are locked, it is possible to prevent the connecting nut 10 from falling off when mounting the metal fitting of the present invention. Therefore, the installation work at a high place becomes very easy. In addition, the connection nut 10 is the connection body 2
Since it is fixed inside, when the suspension rod member Q such as a suspension bolt is screwed to the connection nut 10, it can be easily attached with one hand, and the work efficiency is high. Further, at this time, even if the connecting nut 10 is disengaged from the locking hole 7, the connecting nut 10 is sandwiched between the locking portions 5, so that idling can be prevented.

The metal fitting of the present invention can be inexpensively provided because the whole metal fitting can be formed integrally by bending the band-shaped material.

As described above, according to the present invention, in the construction using the I-type deck plate as the floor plate, the hanging rod member can be mounted at any time regardless of the concrete pouring time, and the mounting work is easy. Even if the position is changed after the attachment, it can be coped with very easily and, in addition, it can be provided at a low price, and various practically useful effects can be obtained.
