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 mounting a support fitting in the deck plate before the mounting of and to mount a support fitting for supporting the hanging rod member in this hole (see FIG. 7).

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, as a floor plate plate replacing the deck plate, an I-shaped protrusion is formed on the lower surface of the plate.
Deck plates are receiving attention. 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-mentioned problems, the present invention has an I
In a hanging rod member support fitting that detachably supports a hanging rod member Q such as a hanging bolt on a floor plate P on which a projecting protrusion P1 of a mold is formed. A pair of connecting bodies 1 is formed which bulges out on both sides of the vertical cross section and is relatively held at both widthwise ends of a pair of reinforcing pieces P2 extended along the longitudinal direction of the ridge P1 so as to be sandwiched between the reinforcing pieces P2. The upper end portion of each connecting body 1 is provided with a sandwiching locking piece 2 that is locked to the reinforcing piece P2, and a tightening hole through which a tightening bolt 20 for tightening both connecting bodies 1 is inserted below the sandwiching locking piece 2. 6 is opened, and on the other hand, the lower end portion of the connecting body 1 is provided with a fastening hole 3 through which the hanging rod member Q is inserted. The stacking and stacking section 4 for stacking the fastening holes 3 of the above, and the hanging rod member Q for mounting on the stacking and stacking section 4 thus polymerized. That is, the locking piece 5 for preventing the rotation of the connecting nut 10 for fixing the screw is formed.

(Operation) That is, according to the present invention, the sandwiching locking piece 2 of each of the pair of connecting bodies 1 is locked to both ends of the reinforcing piece P2 in the width direction, and the tightening bolts 20 inserted into the respective connecting bodies 1 are used. The connecting bodies 1 are tightened, and the connecting body 1 is sandwiched between the reinforcing pieces P2.

The suspension rod member Q passes through the fastening holes 3 of the stacking and stacking section 4 below the connector 1 and is screwed to the connecting nut 10 mounted on the stacking and stacking section 4. The outer surface of the connecting nut 10 is locked to the locking piece 5 when the connecting nut 10 is screwed, and the rotation of the connecting nut 10 itself is prevented.

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

Reference numeral 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 formed 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 connecting body, and a pair is formed so as to face the both ends of the reinforcing piece P2 of the protrusion P1 in the width direction and to be gripped from both sides. The connecting body 1 shown in the figure is formed by bending a band-shaped material.

Then, a sandwiching locking piece 2 that is locked to the reinforcing piece P2 is provided at the upper end of each connecting body 1, and below the sandwiching locking piece 2, a tightening bolt 20 that tightens both the connecting bodies 1 together. A tightening hole 6 through which the thread can be inserted is opened. As described above, since both the connecting bodies 1 are tightened by the tightening bolts 20, the shape of the sandwiching engagement piece 2 can be arbitrarily set. For example, the sandwiching engagement shown in FIG. 1 and FIG. Like the stopper 2, the reinforcing piece P2 is formed in a substantially arc shape so as to grasp the end portion thereof, or as shown in FIG. 6, a hook-shaped sandwiching locking piece 2 is formed which is locked on the upper portion of the reinforcing piece P2. However, the point is that the shape is such that it can be securely fixed when tightening the tightening bolt 20. Further, the tightening holes 6 shown in FIGS. 1 and 2 are formed by bending the central portion of the connecting body 1 so as to overlap each other when tightening, but as shown in FIG. The central portion may be formed linearly.

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 insertion side of the tightening bolt 20 may be a square hole shape or a gourd hole shape described in FIGS. 4 (I) and (II). Further, as the tightening hole 6 on the projecting side of the tightening bolt 20 on the opposite side, as shown in FIG.
And any setting such as the burring shape described in (II) or the round hole shape or the square hole shape when the nut 21 is used is possible.

On the other hand, the lower end portion of the connecting body 1 is provided with a fastening hole 3 through which the hanging rod member Q is inserted, and a mounting overlapping portion 4 and a locking piece 5 are formed at this lower end portion (see FIG. 1). ).

The mounting overlapping portion 4 is formed such that the connecting members 1 that respectively face the lower end portions of the connecting member 1 are bent to form a crocodile, and the fixing holes 3 are overlapped with each other. A connection nut 10 for screwing the hanging rod member Q is placed on the upper portion 4 (see FIG. 2).

Further, the locking piece 5 prevents the connecting nut 10 from rotating, and when the lower end of the connecting body 1 is bent, the mounting overlapping portion 4 is placed.
Is the part that extends upward from. At this time, the locking piece 5 shown in FIG. 3 is formed so that the inner surface of the locking piece 5 forcibly tightens the outer portion of the connecting nut 10 when tightening the tightening bolt 20.

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

That is, 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 hanging rod member Q such as a hanging bolt is attached to the lower surface of the hanging rod member Q regardless of the concrete pouring time. Since it can be detachably supported, it is freed from the troublesome work such as the work of installing an insert before placing concrete like the work using a conventional deck plate.

Moreover, the I-shaped protrusion P1 extends from both lower ends thereof to both sides of the longitudinal section of the ridge P1, and the reinforcing pieces are provided relatively to the width-width end portions of the pair of reinforcing pieces P2 formed along the longitudinal direction of the ridge P1. P2
A pair of connecting bodies 1 to be sandwiched between the connecting bodies 1 are formed, and a sandwiching locking piece 2 to be locked to the reinforcing piece P2 is provided at the upper end of each connecting body 1, and below the sandwiching locking piece 2 are connected. Since the tightening holes 6 through which the tightening bolts 20 for tightening both the body 1 are inserted are opened, even if the mounting position of the suspension rod member Q is changed after the concrete is placed, the mounting position of the support metal fitting itself is changed. It can be changed quite easily.

Further, since the devised metal fitting itself is composed of a pair of connecting bodies 1 which are relatively held at both ends of the width of the reinforcing piece P2 and sandwiched between the reinforcing pieces P2, these connecting bodies 1 are stored or transported. Has the advantage that it can be disassembled into a compact state. Moreover, since the connecting nut 10 is locked in the locking piece 5, the connecting rod 10 has a hanging rod member Q such as a hanging bolt.
When the screw is fastened, the idling of the connecting nut 10 can be prevented, and the work efficiency is high.

As described above, according to the present invention, in the construction using the I-type deck plate for the floor plate, it can be mounted at any time regardless of the concrete pouring time, and the mounting work is easy, and the suspension rod member mounting is possible. Even if the position is changed later, it is possible to cope with various effects that are practically useful, such that it can be accommodated and transported in a compact state, in addition, it can be coped with very easily.
