Description

[Detailed Description of the Invention] The present invention relates to a hanging bolt fixing device for suspending a ceiling base material.

In general, a lightweight steel frame ceiling base structure has a large number of field edge supports A arranged in parallel at equal intervals in the ceiling construction space, as shown in Fig. Many wild people B
are arranged parallel to each other at regular intervals, and connected and fixed at their intersections with appropriate connecting fittings to form a ceiling base.

The field edge support A is suspended horizontally by a hanging pole (C) whose upper end is screwed into a fixing device installed on the underside of the upper floor (not shown) and hung vertically. In order to suspend the receivers A, a plurality of hanging bolts C are required, and therefore, in order to suspend a large number of the frame receivers A on the entire ceiling, an equivalent number of hanging bolts C must be used. become.

When installing and vertically installing a large number of hanging bolts C, screwing the hanging bolts C one by one into the above-mentioned fixtures becomes an extremely complicated work in ceiling construction work, and the screws of the hanging bolts C are If the installation is insufficient, the entire ceiling will not be able to withstand the load after the ceiling base material and ceiling panels are installed.

The present invention is based on the above-mentioned conventional technique for hanging hanging bolts for hanging ceiling base materials, and enables hanging installation by simply inserting hanging bolts, and in particular uses a metal plate folded plate structure deck plate as a floor base. The present invention provides a fixing device that can be installed on a floor structure to allow hanging bolts to be hung.

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

In FIGS. 2 and 3, the four-sided body plate 1a forming the rectangular cylindrical outer cylinder 1 is inclined upwardly in an expanding shape, so that the outer cylinder 1 has a trapezoidal shape, and the upper opening of the outer cylinder 1 is formed. The part can be sealed with a lid body 2, and a fixing plate 3 is integrally connected to the lower part of the outer cylinder 1, and furthermore, a cylinder body 5 with a thread groove 4 carved on the outer periphery is connected to the lower surface of the fixing plate 3. A hole 6 is formed in the fixing plate 3 for inserting a hanging bolt from the cylinder 5 into the outer cylinder 1.

A support member 7 is provided upright within the hollow portion of the outer cylinder 1 between the lid body 2 and the fixing plate 3.

As shown in FIG. 4, this support member 7 is placed on two opposite sides of a rectangular frame 8 having a width interval that is the same as or larger than the inner diameter of the cylinder 5 and the bolt insertion hole 6 diameter. A long guide plate 9 that is sandwiched between the two sides and reaches up to the lid body 2.
are arranged in series, and both side end surfaces of each guide plate 9 face the body plate 1a and serve as guide end surfaces 9a for guiding a clamping body, which will be described later.The guide end surfaces 9a are vertical, and the space between the body plates 1a is upward. According to the above, the holes are formed so as to have wide spacing.

Between both guide end surfaces 9a of the opposing guide plates 9 and the body plate 1a,
A round bar-shaped clamping body 10, which is longer than the interval between opposing guide plates 9, is horizontally mounted.

Both clamping bodies 1 are horizontally suspended between the guide plates 9 in contact with the guide end surface 9a.
0 is smaller than the diameter of the suspension bolt insertion hole 6.

As described above, the body plate 1a has an upwardly expanding and sloping shape, so there is a wide gap upward from the lower part, and the clamping body 10 is positioned downward due to its own weight. The distance between the clamping bodies 10 is the narrowest, and as the clamping bodies 10 move upward along the inclined surface of the body plate 1a, the interval gradually becomes wider. It is larger than 6 diameter.

The present invention has the above-mentioned configuration, and the state of use will be explained next.

In Fig. 5, D indicates the floor structure, which is formed by pouring concrete onto a metal folded deck plate E and curing and hardening it, and the fixing device of the present invention is fixed to the top surface of the deck plate E before concrete is poured. be done.

That is, a mounting screw hole G is formed in the mounting plate E at a location corresponding to the vertical position of the hanging pole F, and this screw hole G is
The cylinder body 5 at the bottom of the fixing plate 3 is screwed into the fixing plate 3, and the fixing plate 3 comes into contact with the upper surface of the deck plate (E), the outer cylinder 1 is fixed upright, and the hanging bolt insertion hole 6 is exposed downwards. .

Once all the fixing devices have been installed and fixed in the required positions, pour concrete and the fixing devices will be buried in the floor structure.

After installing the fixing devices on the floor structure as described above, attach the hanging poles F to each fixing device.

Before insertion of the suspension port 1-F, both the clamping bodies 10 are located below between the outer cylinder 1 and the support member 7 due to their own weight.

If the hanging pole) F is inserted into the outer cylinder 1 from the cylinder body 5 through the insertion hole 6 and raised, the hanging pole) F will hit the clamping body 10 and both side clamping bodies 10 will tilt the outer cylinder 1 due to the hanging pole) F. It is pushed up along the body plate 1a.

If the hanging pole) F is inserted until its upper end surface reaches the lid body 2, the hanging pole) F will be inserted between the clamping bodies 10 at a certain upward movement point.
The distance between the outside diameters becomes the same as that of the outer diameter, and the clamping body 10 slides in contact with the circumferential surface of the hanging pole (F) without rising any further.

When the hanging bolt F is pulled downward at the highest position of the hanging bolt F, the clamping body 10 moves downward along the inclined body plate 1a due to frictional contact and pinches the hanging bolt F from both sides.

That is, at a certain point of the hanging bolt F that is pulled downward, the holding body 10 The hanging bolt F is clamped without rotating, and the hanging bolt F will not come out after that.

Attach the hanging pole) F to each fixing device as above,
After vertical installation, ceiling base materials such as field edge holders and field edges can be hung from the hanging pole F as in the conventional method, and the ceiling can be constructed.

Suspending the ceiling base material and constructing the ceiling adds downward weight to the hanging pole (F), but this weight causes contact pressure, pinching pressure, and friction between the hanging pole (F), the clamping body 10, and the outer cylinder body plate 1a. etc. become even larger, and the clamping of the hanging pole I-F becomes even stronger.

By making the outer surface of the clamping body 10 rough, the frictional resistance becomes large, and the clamping pressure of the hanging poles 1-F becomes even greater and stronger.
