Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is particularly applicable to lightweight cellular concrete walls (Autoclav
ed Lightweight Concrete (hereinafter referred to as “ALC wall”). It relates to a device mounting device for mounting wiring boxes, conduits, ducts, and other devices through a base.

(Prior Art) In recent years, ALC walls are often used as walls and the like as basic materials for construction. Although it is possible to directly insert a wood screw or drive a nail into this ALC wall, it is possible that screws, nails, etc. may come off due to the presence of many voids inside. For this reason, as a nail that can be driven into the ALC wall, as shown in FIG. 30, a fork nail (40) having a repulsive shaft (41) divided into two and curved so as to face outward, respectively. ) Is known.
No. 16485).

Prior to being driven into the wall, the two-way nail (40) has a short cylindrical body (42) at the tip of the shaft (41) facing outward.
As it is driven into the wall, the short cylindrical body (42) is moved along the axis (41) to the head of the forked nail (40). 41) is returned to the original outward direction, and is driven into the wall while expanding.

However, since the above-mentioned towel nail (40) is driven while expanding the inside of the wall by the repulsive force of the shaft (41),
If the wall pressure is strong against the repulsive force, the shaft (41) may not spread well and may not be able to be driven while expanding.
When fixing the device to the wall using such a double-ended nail (40), if the device is thick, the shaft (41)
May be suppressed by the thickness of the object to be fixed, and it may not be possible to drive while expanding.

On the other hand, in order to firmly fix the device, there is known a device in which a nail hole is formed at an angle to a saddle for fixing the device, and the nail is crossed and driven in an X-mark shape (actual opening). Akira
No. 55-161977).

However, in this case, a nail must be driven into each hole, and the work becomes very troublesome as the number of places to be driven increases. Also, unlike the straight driving, the nail must be driven obliquely along the inclined nail hole, so that the driving operation is difficult and troublesome.

(Problems to be Solved by the Invention) Therefore, according to the present invention, a wiring box, a conduit tube, a duct, and other devices can be efficiently mounted on the ALC wall, and can be securely and firmly mounted.
It is another object of the present invention to provide a device mounting device that can mount a device without being affected by the thickness of the device.

(Means for Solving the Problems) That is, the apparatus for mounting an instrument on an ALC wall according to the present invention comprises:
A pair of through-holes having a contact portion to be brought into contact with the wall surface, being drilled in the corresponding contact portion in different directions, into which legs of a forked pin are inserted to forcibly displace the leg angle. And a fork-shaped pin having legs guided by each of the pair of through holes and deforming along the inner surface of the through hole.

(Function) In such a device mounting apparatus according to the present invention, a fork-shaped pin is inserted into a pair of through holes drilled in different directions, and the pin head is straightened from above with a hammer or the like. When struck, each leg of the pin follows the inner surface of the through hole,
It progresses while deforming to the shape of the through hole. Therefore, each leg of the pin can always be advanced in a different direction. In other words, unlike conventional two-way nails, which use the repulsive force of the shaft provided on the nail itself, in other words, the shaft is expanded by using the restoring force of the nail, the pin is inserted inside the through hole itself. Since the legs are expanded, even if the pressure in the wall is strong, the forked pin can be reliably expanded and crossed and driven. Also, by striking the head of the fork-shaped pin straight from above, the legs of the fork-shaped pin can be automatically expanded and driven in a crossed state. The driving operation can be performed more efficiently as compared with the conventional nail driving in which the nail has to be driven diagonally.

Also, even if the equipment to be mounted on the ALC wall is thick, it is through a separate base from the equipment,
The device can be attached without being affected by the thickness of the device.

(Examples) Hereinafter, the present invention will be specifically described according to examples shown in the drawings.

FIG. 1 shows the base (1) of the device mounting apparatus according to the present invention, which can fix the device by screwing or nailing. The base (1) is formed in a plate shape and has a contact portion (1a) for contacting a wall surface. The contact portion (1a) is provided from the upper surface (2) to the lower surface as shown by a chain line in the figure. A pair of through-holes (4a) and (4b) that are curved in opposite directions toward (3), that is, divergently are provided. A forked pin (5) as shown in FIG. 2 is inserted into the pair of through holes (4a) and (4b) (the same applies to other embodiments described below). Configured). Then, as shown in FIG. 3, the pin (5) inserted into the pair of through holes (4a) and (4b) is pushed by the hammer (10) so that the leg (6) of the pin (5) is inserted into the pair of through holes. It advances while expanding along the curved inclined surface (7) of the holes (4a) and (4b) and is driven into the ALC wall (8). The forked pin (5) is desirably made of a soft member that can be easily deformed along the pair of through holes (4a) (4b). This makes it easier to drive the pin (5) into the ALC wall (8).

The pin (5) that has been expanded and driven in this way is more resistant to pulling out from the wall (9) in the vertical direction than the pin (5) whose leg (6) is driven perpendicular to the wall (9). High resistance. Therefore, the base (1) can be securely fixed to the ALC wall (8) having a high porosity.

Further, the upper surface (2) of the base (1) constitutes an instrument mounting portion that can fix the instrument by screwing or nailing. FIG. 4 shows a case where the wiring box (11) is fixed to the base (1) made of synthetic resin by screwing, and a screw insertion hole (12) provided in the bottom wall of the wiring box (11). And the screw insertion hole (1) provided in the base (1).
Align the hole (13) corresponding to 2) with the wood screw (1
By screwing in 4), it is screwed and fixed.

Thus, in the present invention, the base (1) is fixed to the ALC wall (8), and the fixture is fixed to the base (1), so that the fixture is attached to the ALC wall (8).

As shown in FIG. 5, the pair of through holes (4a) and (4b) may be formed in different directions so as to intersect at a diagonal position. .
In this case, the pins (5) inserted into the pair of through holes (4a) and (4b) are displaced diagonally in their legs (6) and inserted into the through holes (4a) and (4b). It is formed so that it can be done.

Also, a pair of through holes (4a) (4
b) forms the curved inclined surface (7), but may be provided so as to simply form the inclined surface (7) in a straight line.
However, if it is curved, the leg (6) of the pin (5)
Can be driven while being spread at a wider angle, and the fixing of the base (1) to the ALC wall (8) becomes strong.

Further, the pair of through holes (4a) and (4b) may be formed as round holes other than the rectangular holes shown in the embodiment.

In addition, a pair of through holes (4a) curved as shown in FIG.
To form (4b), for example, as shown in FIGS. 6 and 7, a hole (15) having a substantially trapezoidal cross section having curved surfaces on both sides is formed, and a gap is provided between the curved surface on both sides of the hole (15). The fitting member (16) having a substantially trapezoidal cross section having a curved surface facing
5) or a pair of holes (17) and (18) having a curved surface as shown in FIGS.
A pair of fitting members (19) each having a substantially triangular cross section and having curved surfaces facing each other with a clearance provided between the curved surfaces of the holes (17) and (18).
(20) should be attached. In this case, the gap forms a pair of through holes (4a) and (4b), and the curved surface forms a curved inclined surface of the pair of through holes (4a) and (4b).
