Description

Description: TECHNICAL FIELD The present invention relates to a suspension construction method for an anemo chamber, which suspends the anemo chamber from a structure such as a slab via a rope.

[Conventional technology]

When installing an air outlet such as an air duct in a building,
In general, a method of suspending a connecting member generally called an anemo chamber from a slab and attaching an air outlet to the anemo chamber to open it on the ceiling finish surface is often adopted. A conventional example of such a suspension construction method for an anemo chamber is shown in FIG. 4, for example. This is a structure in which a female slab 1 or a beam is fixedly mounted with an insert 2 having an internal thread.
The upper end of the bolt 3 made of long steel, which is measured and cut according to the hanging position of the anemo chamber, is fixed with a screw, and the anemo chamber 4 is suspended at the other end. The anemone chamber 4 has an insertion hole for the bolt 3 formed in the ceiling portion, while the lower end of the bolt 3 is threaded similarly to the upper end. The lower end portion of the bolt 3 is passed through the insertion hole, and the nut 5 is used. Attach the anemochamber 4 by screwing. In this way, the flexible duct 9 is attached to the anemo chamber 4. When performing ceiling finishing, the nut 5 is loosened, the anemo chamber 4 is lowered along the bolt 3 as shown in FIG. 5, and is lowered onto the ceiling finishing board 6.

Then, after the finished surface is made, the anemo chamber 4 again
Is lifted up along the bolt 3 and fixed by the nut 5, and the outlet 8 is connected to the lower opening 7 of the anemo chamber 4, and the outlet opening is the opening of the ceiling finishing surface.
Fixed at 10. In addition, on the side surface of the anemo chamber 4,
As described above, the flexible duct 9 is connected to supply the air flow.

[Problems to be Solved by the Invention]

However, in such a conventional anemo chamber suspension construction method, the bolt 3 made of long steel is hung from the slab 1 and the anemo chamber 4 is fixed to the tip of the bolt 3 by tightening the nut. If the position where the bolt 3 hangs from the slab 1 and the opening 10 of the ceiling finishing board 6 are misaligned, the construction of the site may be troublesome because the anemo chamber 4 is provided and the outlet 8 is attached.
Further, since the anemo chamber 4 is fixed to the bolt 3 by the nut 5, it is necessary to measure and cut the length of the bolt one by one, and there is a problem that the work for this is troublesome.

The present invention has been made in view of such conventional problems, and an object thereof is to provide an anemo even if there is a deviation between a position of a support member hanging down from a slab and a blowout port mounting opening of a ceiling finishing surface. It is an object of the present invention to provide a suspension construction method for an anemo chamber that can be easily attached to a chamber and can improve the efficiency of suspension work.

[Means for Solving the Problems]

This invention, the rope suspended from the bottom surface of the building slab,
Insert into the one-way locking device grip attached to the anemo chamber, temporarily suspend the anemo chamber,
Next, while releasing the one-way locking of the instrument grip with respect to the rope, after connecting the anemo chamber to the flexible duct, pull down the anemo chamber near the opening of the ceiling finishing board that was installed at the planned blowing position. The outlet is attached.

[Action]

In the present invention, the cord is used as a support member, which is one-way locked to the instrument grip attached to the anemo chamber, and the one-way lock is releasably attached, so that the attachment / detachment to / from the anemo chamber can be performed with one touch. The installation position of the equipment can be set flexibly, and various construction work can be performed quickly and safely.

[Embodiment] FIGS. 1 and 2 are views showing an embodiment of a suspension construction method for an anemo chamber according to the present invention. In this embodiment, as shown in FIG. 2, an insert 2 is fixed to a slab 1, and a wire 11 as a cord is joined to the insert 2. Therefore, the upper end of the wire 11 is inserted into the hanging base attachment grip 12 so that it can be easily moved in the inserting direction, but cannot be pulled out in the downward pulling direction. The grip 12 is attached to the insert 2 provided on the slab 1 by screwing. The wire 11 prepared at this time is set somewhat longer depending on the distance between the slab 1 and the ceiling finishing board. In addition to the wire 11, a plastic filament having high tensile strength can be used as the cord. The suspension of the wire 11 from the lower surface of the slab of the building in the present invention is performed by caulking the wire in the insert 2 in place of the grip 12 for mounting the suspension base in FIG. This can also be achieved by a publicly known one using the above ball, or one directly suspended on a slab.

FIG. 1 shows a mounting structure of the wire 11 and the anemo chamber 4, a through hole 13 is provided at the center of the top of the anemo chamber 4, and a nut having a screw hole communicating with the through hole 13 is provided.
14 is fixed to the anemo chamber 4 by welding or the like. An instrument grip 15 is screwed into the screw hole of the nut 14.

Then, the wire 11 is attached to the instrument grip 15 so as to be locked in one direction. That is, the instrument grip 15
The lower end of the wire 11 suspended from the suspension attachment grip 12 as described above is inserted, and although it moves in the insertion direction, it cannot be removed in the upward extraction direction. An instrument grip 15 is attached to the wire 11. Therefore, the anemo chamber 4 as an instrument is temporarily suspended on the slab 1 via the wire 11.

Next, in this temporary suspension state, the flexible duct 9 is connected to the side opening of the anemo chamber 4 so that ventilation can be introduced into the anemo chamber 4.

Here, the ceiling base is constructed, the ceiling finishing board 6 is attached, the opening 10 is provided in the ceiling finishing board 6 at the planned blowing position, and the anemochamber 4 which has been temporarily hung up until now is wire-operated by the instrument grip 15. While forcibly releasing the pressure action of 11, while pulling it down close to the opening 10, between this opening 10 and the blowing opening 16 of the anemo chamber 4,
Attach the outlet 17.

In addition, depending on the convenience of suspended construction, from the attachment of the wire 11 to the above-mentioned suspension base attachment grip 12 to the outlet 17
It is also possible to arbitrarily change the order of one or more of the steps up to the step of attaching. For example, the wire inserting step for the hanging base attaching grip and the first grip attaching step for the insert are reversed, or the wire inserting step and the second grip attaching step for attaching the instrument grip to the anemo chamber 4 are reversed. Can be installed from the beginning by factory assembly.

Further, the instrument grip 15 used in the present invention, as shown in FIG. 3, for example, has a tapered hole 21 whose diameter gradually increases from the upper side to the lower side, and stroke motion in the hole 21 in the vertical direction. The slider 22 thus arranged and a spring 23 as an elastic member for constantly urging the slider 22 upward. The hole 21 has an open lower end, and the spring is
A stop seat 24 is attached to the lower end of the grip body so as to close the hole 21 in order to accommodate 23 and the like. The slider 22 has a hollow hole 25 penetrating and extending in the longitudinal direction (vertical direction in FIG. 2), and a housing hole 26 extending in a direction intersecting the longitudinal direction at the upper end portion of the slider 22. A ball 27 is accommodated in the accommodation hole 26. For example, one ball 27 is housed inside the housing hole 26 (three balls in total). A guide hole 28 connected to the hole 21 is provided above the hole 21 of the grip.
Are formed. The wire 11 hanging from the slab 1 enters the hole 21 through the guide hole 28 and extends downward through the hollow hole 25 of the slider 22. Meanwhile, in the slider 22, it extends through between the balls 27, and when the spring 23 pushes the slider 22 upward, the ball 27 is pushed by the tapered surface of the hole 21 and locked to the wire 11, Fix the grip body to the wire 11. A hook 29 is attached to the lower end of the slider 22,
As shown in FIG. 1, by hooking a key member or the like and pulling it downward, the engagement between the ball 27 and the wire 11 can be forcibly released. Therefore, gravity acts on the anemo chamber 4 through the wire 11 and tries to descend downward. This is in grip 15
The upward movement of the slider 22 is promoted and the ball 27 is tightly engaged with the wire 11 to support the anemochamber 4.
In this state, the anemo chamber 4 is used to finish the ceiling.
In order to lower, the key member is inserted into the anemo chamber 4, hooked on the hook 29 and pulled downward, the slider 22 moves downward in the grip 15 and the ball 27 and the wire 11 are pulled.
Is unlocked. Therefore, the anemo chamber 4 moves downward with respect to the wire 11 and is lowered to a predetermined position.
Then, after the ceiling finish surface is created, if the anemo chamber 4 is pushed upward while supporting the wire, a downward force is applied to the slider 22 to loosen the engagement between the ball 27 and the wire 11.
The anemo chamber 4 can be pushed up. In this way, the anemo chamber 4 can be raised and lowered by a very simple operation, and even if the opening of the outlet and the attachment position of the wire 11 are deviated, the anemo chamber can be attached properly.

Further, the suspension base mounting grip basically restricts the movement of the wire 11 in the descending direction (disengagement direction), while allowing the movement in the opposite direction.

〔The invention's effect〕

As described above, according to the present invention, the cord suspended from the lower surface of the slab of the building is inserted into the instrument grip attached to the anemo chamber, and attached so as to be locked in one direction. Temporarily suspend,
Next, after connecting the anemo chamber to the flexible duct, while releasing the one-way locking of the grip for the instrument with respect to the rope, pull down the anemo chamber near the opening provided at the planned blowing position of the ceiling finishing board and blow it. Since the mouth is attached, the installation of the anemo chamber can be performed safely, reliably and easily even at high places without being greatly affected by the opening position of the outlet, and the anemo chamber can be raised and lowered during ceiling finishing work etc. This can be easily performed, and the number of working steps can be reduced, and working efficiency can be improved. Furthermore, part of the process is factory work,
Work time on site can be reduced.
