Description

[Detailed Description of the Invention] (Industrial field of application) This invention is intended to hold pipes and wires such as conduits and cables in the construction of electrical equipment, and especially to the lip portion of lip grooved steel. Related to the piping and wiring that can be attached with one touch.

(Prior Art) Conventionally, pipes and the like are sandwiched between a pair of elastic sandwiching plates 10 as metal fittings for attaching pipes and wiring to the lip grooved steel, and the lower end of this elastic sandwiching plate 10 is made of lip grooved steel. In addition to being locked to the lip portion, the upper end portion of the elastic sandwiching plate is connected with the bolt 11 to sandwich and fix the pipe or the like on the lip channel steel S (see FIG. 5).

In addition, as an improvement of this kind of metal fittings, the applicant of the present invention
Various types of piping and wiring mounting brackets have been proposed (Actual Kosho 55)
-5829 and Japanese Utility Model Publication No. 55-54144).

The former improvement is that the bolts are not used when connecting the upper part of the elastic sandwiching plate, but the upper part of the elastic sandwiching plate is bent and formed so that the connecting pieces that repel each other with their own elastic force are locked to each other. In particular, the latching claw protruding from one of the connecting pieces is locked in the latching hole formed in the other connecting piece, and is locked and coupled by its own elastic force. (Actual No. Sho 55-5829).

The latter piping and wiring mounting metal fittings are further improvements of the former metal fittings, and in particular, an elastic temporary fixing body that connects the engaging pieces provided at the lower end of the elastic sandwiching plate is formed. (See Japanese Utility Model Publication No. 55-54144).

(Problems to be solved by the invention) The following drawbacks have been originally recognized in the conventional metal fittings in which the elastic sandwiching plates are fixed by screws.

Since the metal fitting is composed of a pair of elastic sandwiching plates 10, bolts 11 and nuts, the mounting work of the metal fittings is extremely troublesome, and one elastic sandwiching plate is used in order to omit the use of the nut. 1
If a tap screw or the like is formed in 0, the insertion direction of the bolt 11 will be restricted, but since the pair of elastic sandwiching plates 10 have a symmetrical shape, the elastic sandwiching plate 10 through which the bolt 11 is inserted is formed. It is easy to make a mistake and there is a lot of loss time due to re-installation work, and because the tightening direction of the bolts 11 is performed at a position perpendicular to the longitudinal direction between the wires, etc. In the case of a large protrusion, it becomes difficult to fix the adjacent electric conduits, and the protruding bolts 11 hinder the fixation of the electric conduits in a close contact state.

Therefore, the applicant has solved the above-mentioned problems by the above-mentioned improvement application, but new problems have arisen here.

That is, in the former improvement application, the electric wire tube or the like is clamped and fixed by utilizing the elastic force of the elastic clamp plate itself.
When the upper end of the elastic sandwiching plate is strongly pinched with a tool such as pliers to lock and connect the upper end of the elastic sandwiching plate, the lower end of the elastic sandwiching plate fixed to the lip channel steel is recoiled by tightening the upper end. There was a risk that it would spread greatly.

In addition, in the latter improvement application, in order to solve such a problem, a metal fitting in which an elastic temporary fixing body that connects the lower end portions of the elastic sandwiching plates to each other is formed is proposed. However, this elastic temporary fixing body is formed separately from the elastic sandwiching plate, and when in use, the elastic temporary fixing body is previously hooked on the lower end of the elastic sandwiching plate, and this state is While maintaining, it was necessary to engage the elastic sandwiching plate with the lip channel steel and clamp and fix the pipe and the like. Therefore, in addition to the time and effort required to attach the elastic temporary fixing body and the elastic sandwiching plate, the manufacturing cost of the elastic temporary fixing body is added to the manufacturing cost of the metal fitting, resulting in an inconvenience that the overall price becomes extremely high. .

Moreover, when the elastic temporary fixing body is strongly sandwiched by a tool such as pliers for locking and connecting the upper end portion of the elastic sandwiching plate, this recoil causes the elastic temporary fixing body to largely expand in the expanding direction. Especially, since the lower end of the elastic sandwiching plate expands in proportion to the tightening distance of the upper end of the elastic sandwiching plate, it takes time to lock the elastic sandwiching plate while firmly sandwiching it with a tool such as pliers. As a result, the elastic temporary fixing body attached to the lower end of the elastic sandwiching plate may be damaged and may not be used.

Therefore, this invention has been devised to solve the above-mentioned various problems and inconveniences, and it can be attached with one touch without any screwing, and at the same time, while saving labor of the installation work, An object of the present invention is to provide a pipe / wiring mounting bracket that can maintain a reliable holding force that has not been obtained in the past for a long period of time.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the invention is to fix and fix pipes and wirings on a predetermined lip grooved steel S by a pair of sandwich plates 1 in the form of strips. Each of the sandwiching plates 1 is an attachment piece 2 that is provided at the lower end of the sandwiching plate 1 and engages with a lip portion S1 of a predetermined lip channel steel S.
And a sandwiching piece 3 that extends from the engaging piece 2 and sandwiches the pipe and wiring on the lip channel steel S, and a mutual extension that is bent and extended above the sandwiching piece 3 and repels each other by its own elastic force. In the pipe and the wiring mounting metal fitting, which are connected to each other and connect the upper end of the sandwiching plate 1 to each other, extend from the side surface of each sandwiching piece 3 and, when connecting the upper connecting strips 4, An auxiliary arm 5 is provided that presses the side surface to the upper portion and prevents the engagement piece 2 from expanding. A lower connection piece 6 that engages and connects the lower end portions of the engagement piece 2 with each other.
Is extended and bent from the lower end of each engaging piece 2 to provide means for solving the problem.

(Operation) That is, according to the present invention, the auxiliary arms 5 extended from the sandwiching pieces 3 are pressed against each other from the side surface of the pipe or the like at the time of connecting the upper connecting pieces 4 to spread the engaging pieces 2. Prevent.

Further, the lower connecting piece 6 bent and extended from the lower end of each engaging piece 2
In the lip portion S1 of the lip channel steel S, the lower end portions of the engaging pieces 2 are locked and coupled to each other.

Then, the upper connecting pieces 4 that are bent and extended above the sandwiching piece 3 and repel each other by their own elastic force are locked to each other, and the upper end portion of the sandwiching plate 1 is connected by its own elastic force. The upper and lower plates are continuous, and a pair of sandwiching plates sandwiching pipes or the like form a substantially loop shape, and the elastic force of the sandwiching plate 1 itself brings the entire metal fitting into a tightened state.

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

The structure of this invention metal fitting is composed of a pair of sandwich plates 1 in the form of strips.
(See FIG. 4).

Each sandwiching plate 1 is provided with an engaging piece 2 provided at a lower end portion of the sandwiching plate 1 and engaged with a lip portion S1 of a predetermined lip channel steel S, respectively.
A sandwiching piece 3 which is extended from the engaging piece 2 and sandwiches pipes and wirings on the lip channel steel S, and a sandwiching plate which is bent and extended above the sandwiching piece 3 and is locked to each other by its own elastic force. 1 and an upper connecting piece 4 for connecting the upper ends of the engaging pieces 1, and a lower connecting piece 6 for bending and extending from the lower ends of the engaging pieces 2 to lock and connect the lower ends of the engaging pieces 2 (first See figure).

The sandwich plate 1 is formed by bending a strip plate, and an elastic metal plate such as spring steel is planned to be used. Other materials such as plastic can also be used.

The engaging piece 2 is formed on the lower end portion of the sandwiching plate 1, and has a notch 2A that engages with the bent tip of the lip portion S1 of the lip channel steel S. The engaging piece 2 below the notch 2A is inserted into the lip of the lip S1 (see FIG. 3).

The sandwiching piece 3 is bent so as to match the side surface shape of piping, wiring, and the like. In the sandwiching piece 3 of the illustrated example, the sandwiching plate 1 extended from the engaging piece 2 is bent in a curved shape from the side surface of the pipe to the shoulder portion of the pipe (see FIG. 1).

The upper connecting piece 4 is bent and extended upward from the sandwiching piece 3, and in the illustrated example, a hooking claw 4A and a hooking hole 4B that lock each other by repulsing each other by their own elastic force. Are provided one by one, and the upper connecting pieces 4 are connected to each other by locking one hooking claw 4A in the other hooking hole 4B (see FIG. 2). The upper connecting piece 4 has a rising portion 4C extending from the sandwiching piece 3 and a rising portion 4C.
It is composed of a locking portion 4D which is bent in the direction of the sandwiching plate 1 facing from C, and a locking claw 4A and a locking hole 4B are formed in this locking portion 4D. And the upper connecting piece 4 of both
When is forcibly pressed inward, the upper connecting pieces 4 repel each other outward due to the elastic force of the upper connecting pieces 4 themselves. The upper connecting pieces 4 that repel each other are locked by the hooks 4A and the hook holes 4B to connect the upper ends of the sandwiching plates 1.

The auxiliary arm 5 extends from the side surface of the sandwiching piece 3, and the connecting piece 4
At the time of connection, pressure contact is made from the side surface of the pipe or the like to the upper portion (see FIG. 1). At this time, in the auxiliary arm 5 of the illustrated example, a part of the connecting piece 4 extending from the sandwiching piece 3 is cut out and bent to form the auxiliary arm 5 (third embodiment).
See figure).

The lower connecting pieces 6 lock and connect the lower end portions of the engaging pieces 2 to each other, and are bent and extended from the lower ends of the engaging pieces 2.
In the illustrated example, one lower connecting piece 6 is provided with an engaging hole 6A, and the other lower connecting piece 6 is provided with an inserting piece 6B which is inserted and locked in the engaging hole 6A. Are to be engaged. At this time, although the insertion piece 6B is bent downward, the insertion piece 6B may be bent upward without being limited to the illustrated example, and the point is that both can be engaged. Also,
Although not shown, a cutout having a substantially U shape is provided on the plate surface of the lower connection piece 6, and the inside of this cutout portion is folded back to form the insertion piece 6B, and the trace of the insertion piece 6B folded back. It is also possible to use the opening portion of as the engaging hole 6B. By doing so, the pair of sandwiching plates can be formed in a symmetrical shape, and the manufacturing cost can be rationalized.

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

That is, each of the sandwiching pieces 3 is extended from the side surface thereof, and when the connecting pieces 4 are connected, they are pressed against each other from the side surface of the pipe or the like to the upper side, and the sandwiching plate 1
By providing the auxiliary arm 5 for preventing the lower end from expanding, the elastic repulsive force of the connecting piece 4 is generated upward from the side surface of the sandwiching piece 3 and the expanding downward from the side surface of the sandwiching piece 3 is prevented. Since it is regulated by the auxiliary arm 5, the portion of the engaging piece 2 does not spread.

Therefore, the engagement piece 2 can be prevented from expanding in proportion to the tightening distance of the upper connecting piece 4. As a result, if it takes time to lock the upper connecting piece 4 while it is strongly sandwiched by a tool such as pliers like a conventional support fitting, the elastic temporary fixing body connected to the engaging piece 2 is damaged, The fear of becoming unusable has been resolved.

Further, since the lower connecting pieces 6 for locking and connecting the lower ends of the engaging pieces 2 are bent and extended from the lower ends of the respective engaging pieces 2, the upper and lower sides of the holding plate 1 are fixed when the electric wire tube or the like is held and fixed. A pair of sandwiching plates, which are continuous and sandwiching pipes and the like, form a substantially loop shape, and the elastic force of the sandwiching plate 1 itself brings the entire metal fitting into the tightened state.

In this way, since the sandwiching plate is fixed to the lip grooved steel S in a looped state, there is no fear that the sandwiching and holding force of the conduit or the like will gradually decrease. For these reasons, it is possible to maintain a reliable holding and holding force, which has not been obtained in the past, for a long period of time.

Moreover, since the metal fitting of the present invention can be formed by processing a pair of sandwiching plates 1 in the form of strips, the manufacturing cost is the same as the conventional metal fitting in which the elastic temporary fixing body is provided separately from the sandwiching plate. The inconvenience of high cost has been resolved.

Further, the metal fittings of the present invention can be connected to the upper end portions of the sandwiching plates 1 only by engaging with each other by bending and extending above the sandwiching pieces 3 and repulsing each other by their own elastic force. Can be installed with one touch without the need for
Labor saving in mounting work can be achieved.

Thus, according to the present invention, it is possible to attach with one touch without any screwing, and
While achieving labor saving in the mounting work, various practically useful effects can be obtained, such as being able to maintain a reliable clamping and holding force, which has not been obtained in the past, for a long period of time.
