Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for attaching a buried body buried in concrete to an inaccessible position of a temporary concrete frame, and a method for attaching a buried body buried in concrete to an inaccessible position in a concrete temporary frame. Buried objects such as outlet boxes or switch boxes for wiring are buried. Generally, these buried bodies are buried by attaching the buried body to the inner surface of the temporary concrete frame after it has been erected, and then pouring ready-mixed concrete into the temporary frame.

Currently, construction workers who assemble temporary frames and pour fresh concrete are generally separated from electrical workers who install buried objects such as outlet sockets. This is due to the fact that the workers have to work in between the construction workers' work. Therefore, the temporary frames are usually placed side by side at such narrow intervals that it is impossible for one person to work on them, and furthermore, the mounting position of buried objects such as out left boxes is so far away that it is impossible for people to reach them. These cannot be installed using normal methods.

, and insert the hook bolt into the through hole from the outside of the temporary frame where it is easy to work. At the same time, lower the outlet box from the end of the temporary frame, engage the hook gelt with the hook provided on the out left box, and then The method used was to tighten the hook bolt from the outside of the frame. However, this method causes major damage to the temporary frame due to the holes being drilled, and requires two workers: one to insert the seven bolts from the outside, and the other to climb onto the top of the high temporary frame and lower the outleft box from there. Minimum required. Furthermore, the person inserting the 7x21il cannot see the outlet box because it is blocked by the temporary frame, and therefore has no choice but to communicate by shouting to each other without seeing the outleft box, which is extremely inefficient. Met.

It is an object of the present invention to solve the above-mentioned drawbacks and to efficiently mount a buried object such as an outleft box in a far out-of-reach position with a small number of workers.

However, as shown in Figures 1 and 2, a recent method for installing an outleft box at a distance is to fix the base (2) inside the box (1), which is a buried body.
) with a screw shaft (3) protruding from it, an advancing/retracting member (4) screwed onto the screw shaft (3), and a wood screw (5) protruding from the advancing/retracting member (4). is proposed. Konomo!
This method uses a device related to tllllNli8is-86317. In this case, the box (1) is fixed with the tension device (6) and the advancing/retracting member (4) is rotated to screw the wood screw (5) into the temporary frame (7), and then the box ( 1) are attached to the temporary frame (7) integrally and simultaneously with the wood screws (5). In the case of this method, as is clear from the description on page 6 to line 8 of the specification at the time of publication of JP-A-56-86317, the advancing/retracting member (4) and the screw shaft (3) are always screwed together. Therefore, the box (1) and wood screw (6), which are buried objects, must be

1) and the wood screws (5) can only be attached integrally and at the same time. Therefore, the screw shaft (3), which is a device, and the advancing/retracting member (4)
) Many parts of the base (2) 411 must be directly assembled into the buried body, the boss (1) itself,
It was extremely inefficient. Furthermore, buried objects with extremely limited sizes and shapes that have space to store various parts,
That is, it can only be used for box-shaped buried objects, and cannot be used for buried objects of a size and shape that cannot accommodate the above-mentioned parts, that is, pipe-shaped or plate-shaped buried objects, and is lacking in versatility. In addition, the box (
1) It is necessary to empty the inside, so 65-16317
As is clear from the description from page g1g to line Ao of the specification at the time of publication of the issue, after the temporary frame (7) was removed, the electrical worker went to the work site again and took a break from the construction worker's work. It was necessary to remove all the parts from the box (1) by removing them from the box (1), further reducing efficiency. It is also an object of the method of the present invention to overcome the problems of lack of versatility and reduced efficiency that occur in the method using the apparatus of JP-A-66-86317.

The method according to the invention is intended for mounting an embedded object in a fast mounting position that is out of human reach. That is, the method according to the present invention provides a rotary drive shaft at a remote mounting position, changes the direction of this rotation in a direction that intersects the longitudinal direction of the rotary drive shaft, and thereby advances the screw to remove the concrete temporary frame. The main feature is that the device is attached with a predetermined length exposed, and after the screw is installed, the locking tool of the buried body is hooked to the exposed portion of the screw. That is, the method according to the present invention is a method for installing a buried object such as an outlet box or a switch in a position far away from the reach of humans, and the method involves changing the direction of rotation of the rotary drive shaft to the forward direction of the screw. This causes the screw to be installed in the concrete temporary frame with a predetermined length exposed, and then the exposed part of the screw is hooked with the locking tool of the buried object to be buried in the concrete. This is for installing a buried object. In this way, since the screw is first attached and then the locking tool for the buried object is hooked, unlike the invention of JP-A-55-86317, which attaches the screw and the buried object simultaneously, the device Screw shaft (3) Moving member (4) Base (2)
There is no need to directly incorporate many various parts such as into the buried body itself, and of course there is no need to remove and empty the parts after the temporary frame (7) is removed, resulting in good work efficiency. Furthermore, since there is no need to incorporate various parts into the buried body itself, there are no restrictions on the size and shape of the buried body, and therefore the buried body may be in the shape of a pipe or a plate, making it highly versatile.

The purpose of the screw according to the invention is also to be used directly in the implementation of this method and to be installed in an exposed position. This structure includes a head, a threaded part, a locking part corresponding to the buried object locking tool provided in the middle, and a stopper provided at the boundary between the locking part and the threaded part.

Hereinafter, the above-described mounting method and screws will be explained in more detail with reference to the drawings. First, for convenience of explanation, regarding the screw mounting device and screw used in the mounting method according to the present invention (1)
), and then (1) the mounting method according to the present invention.
I will explain.

(1) In FIG. 3, which shows a side view of the entire screw mounting device, Ql is a rotational drive shaft. (2) is a long operation box that houses a rotary drive shaft (b), and a scale part (to) for detecting the screw mounting height position is provided on the shoulder wall of the box. 0◆ is a box provided at the lower end of the operation box 4. Fourth
The figure is a perspective view of this, and FIG. 6 is a front view.

Furthermore, Figs. 6 and 7 show the inside of the box Q(l), and as is clear from these figures, the rotational drive axis θυ
has a worm at its lower end. aQ is a worm wheel for changing the direction of rotation of the rotary drive shaft αυ to the forward direction of the screw, and this worm wheel αQ
is meshed with the worm (c) and rotated by the rotational axis 0υ. In Figure 8, αη
is a screw for attaching the buried object, and the head (t7a)
It consists of a threaded part (17(1)), a stopper (17o), and a locking part (17b). In this embodiment, the head (17m) of the screw αη is hexagonal, and the locking part (17b)
) are tapered in this example, with diameters decreasing in order from (17a). In this example, the stopper (1
Although 7o) is in the shape of a flange, it is not limited to this, and may be a mere protrusion. Is the stopper screw Q? ) is installed in an exposed state.In Figures 6 and 7, (to) is a screw fixing part attached to one side of the worm wheel aQ with a bolt (2), and by its installation, It is designed to entrain and rotate with the worm foil αQ. In this embodiment, the screw fixing portion has a hexagonal hole in the center. 2) is a magnet provided in the center of the worm foil aQ facing the hole 2).

Then, insert the screw a''I) into the hole (1) from the head (17m) side, and make the hexagonal head (17m) and hexagonal hole (E) fit into the concave and convex shape, The screw 07) and the screw fixing part (to) are made to rotate together.At this time, if the screw head (y&) is made of a magnetic material other than steel, the screw head (17m) will be attached to the magnet ( b), and can be prevented from coming off.When the screw a71 is rotated to the screw fixing part (end) in this way, the screw head (17a) fits into the hole (4) unevenly. Therefore, it can be said that the screw Q't) is in a removable state.

As described above, when the rigid rotation drive shaft is rotated with the screw αη fixed, this rotation is slowed down and speeded up through the worm wheel 0Q, and the direction is changed and fixed. It is transmitted to the screw αη, and therefore the screw αη rotates. Therefore, if the exposed end portion of the screw α force is bitten into the temporary frame, as the screw 071 rotates, the screw aη will advance in the direction indicated by the arrow shown in FIG. Here, the worm wheel serves to convert the rotation of the rotary drive shaft αυ into the forward rotational direction of the screw Q7).

1) Having finished the explanation of the screw attachment device above, the remote attachment method of the buried object will be explained in detail below with reference to FIGS. 9 to U. (Note that in this case, unlike the one in Figure 3, the cover (2) is attached.) First, as shown in Figure 9, from the upper end side of the temporary frame, the entire screw mounting device (B) is attached. φ~ Loosen. At this time, if the height position Itwo is detected by the scale part (to) through the expansion and contraction of the operation box (6) and the cover (to),
It is convenient because the mounting height position of the screw Qη can be adjusted completely. Also, at this time, use a spirit level (2) to check whether the mounting fl (M) is tilted. and the device) in its normal position,
By pressing the device (goods) in the direction of arrow 0 as shown in FIG. 9, the exposed tip of the screw (goods) is forced into a temporary frame (goods) made of wood such as a plywood board. and,
A hand-held electric drill (to) as shown in Figure U is connected to the rotating drive shaft (
(b) and drive it. Of course, it may be driven by other means than the hand-held electric drill. As a result of such driving, the screw αη automatically screws into the temporary frame (C) by self-tapping, and advances until the stopper (17a) comes into contact with the surface of the temporary frame (material). The screw according to the present invention is No. sv! Stopper (17a) as shown in J
Since this is provided, there is an effect that the screw Qf) will not spiral any further. Therefore, as shown in Figure ν, screw (17) t-
Install the screw Q't to ensure that the specified length is exposed.
The installation method is not limited to the one shown in Figure 9, but also the one shown in Figure 11.
As shown in the figure, a bridge structure may be provided to hold the screw mounting device W (material) open in the temporary frame (material). In this case, the height is adjusted by inserting the screw (25) of the frame (26 m) into the desired position of the device (goods), then
As shown in Fig. 10, by moving the upper end of the device (goods) in the direction of arrow P, the lower end of the device (width) is made to make a pendulum movement in the direction of arrow E using the screw (26) as a fulcrum, and by this pendulum movement, the screw α force is Make sure to insert the tip into the temporary frame (c).

Now, once you have completed installing the screw Q7) in a far away position of the concrete temporary frame (goods) that is out of reach of people with the predetermined length exposed using the above method, the next step will be as shown in Figure 12. Next, lower the buried body support such as the left box from the upper end of the temporary frame (goods), and tighten the buried body retaining tool (goods) with the screws Qf).
The exposed part, especially the locking part (17b), is hooked on, thereby attaching the buried body canopy to a position far out of reach of people. In this sense, the locking portion (17k) can be said to correspond to the buried object locking tool (2). Unlike conventional methods, the present invention does not require a person to insert the hook bolt from the outside of the temporary frame, and only requires a person at the end of the temporary frame, which has the effect of attaching the buried object with fewer people. As described above, in the mounting method according to the present invention, after installing the screw Q force, this screw α
Since the force is multiplied by the buried body (b) by 1, unlike the method using the device of JP-A-65-86317, the screw shaft (3) advancing/retracting member (4) pace (2)
It is not necessary to directly incorporate many various parts such as into the buried object (goods) itself, and therefore, there is an advantage that they can be attached regardless of the size and shape of the buried object. Of course, Japanese Patent Application Publication No. 1973
-! Unlike the method using the 16117 device, the six-layer WII method incorporates the various components described above directly into the buried body itself.
This method is more efficient than the method disclosed in JP-A-65-65-5S because it eliminates the six-layered and troublesome process of removing these various parts one by one from the buried body and emptying the buried body. good.

In addition, when attaching a buried body holder such as an outref) to the screw Qη,
In the case of the embodiment shown in the drawings, the buried body (

617. In this case, ■ is the cut and raised piece for attaching the buried body, 2) is the locking hole, - is the bent piece, 1B8) is the sloped part for locking guide, and the cut and raised piece (to) Alternatively, adhesive tape for the number of buried bodies may be attached as shown in Figure 3. Even in the installed state, as shown in Fig. 14, the space between the bent pieces presses against the tapered part of the locking part (17b) of the screw Qη due to the spring action, thereby preventing the buried object (b) or the locking tool from being attached. (E) is definitely stopped so that it does not move.

It goes without saying that instead of this, the locking tool and the buried body may be made integrally as shown in Figure 1.

Also, regarding the screw α, the head (17m) is hexagonal in the case of this peeling, but instead of this, the head (3) of the screw (on) has a stopper (87o) as shown in No.
76L) may be shaped like a gear. In this case, the rotational driving force of the spur gear 76L can be reliably transmitted due to the gear toothing structure. Also, it goes without saying that the screws may be arranged as shown in Fig. 19, where (to) the inserter F.
Acid-forming resin is used for forming a taper which is inserted later. The head of the screw may be square as shown in FIG. 20 (in this case, the screw fixing portion may be provided with a hexagonal protrusion so as to fit into the concave and convex portion), or it may be a spline.
