Description

[Detailed description of the invention] This invention relates to a cross-connector between rod-shaped members,
It is used to connect and support bar-shaped members at appropriate intersection angles, for example, by suspending lightweight channel steel materials for supporting conduit pipes, cable racks for running cables, and other electrical equipment materials from ceiling slabs, etc. In order to prevent swinging of the hanging bolts and improve the installation stability of the electrical equipment material, the hanging bolts are cross-connected to the rod-shaped hollow members installed between the hanging bolts. The present invention relates to a cross-connecting tool for mutually connecting rod-shaped members.

Conventionally, when supporting various electrical equipment materials using hanging bolts, reinforcing bars, and other hanging rod members suspended from a ceiling slab, etc., the distance from the ceiling slab surface to the supporting position may be long, and as a result, the electrical equipment materials are It sways from side to side, which can be dangerous during piping and wiring work such as conduits and cables, and even after support. In order to solve this problem, a vibration prevention device for wiring devices was proposed, such as the one disclosed in Japanese Utility Model Publication No. 56-11557, but the connecting rod member was re-attached from a different location from the hanging position of the hanging rod member. It has been found that it is troublesome to connect at an angle, and the handling is complicated because there are many screwed parts.

Therefore, this idea was devised to solve the above-mentioned conventional drawbacks, and when suspending and supporting lightweight channel steel materials for supporting conduit pipes, cable racks for running cables, and other electrical equipment materials, Focusing on the fact that hanging rod members such as hanging bolts are used in multiple pairs, we have decided to extremely effectively prevent the shaking phenomenon by installing and fixing rod-shaped hollow members between them. It was a success.

That is, when the main plate of the metal fitting is bent against the elasticity of the main plate of the metal fitting, one of the rod-shaped members is inserted into the vicinity of both longitudinal ends of the main plate of the metal fitting, which has elasticity, and the main plate of the metal fitting tries to return to its original state. A mounting portion having an inner circumferential edge surface that comes into pressure contact with the rod-shaped member due to the elastic return force generated when the fitting is used is provided, and the other rod-shaped member that intersects with the one rod-shaped member is attached to the flat connecting portion provided approximately at the center of the main plate of the metal fitting. A cross-support plate with a generally groove-shaped cross section, in which a support groove with a V-shaped edge surface that fits into the member is cut out in the side wall, is rotatably connected at the bottom wall of the cross-support plate, thereby making it possible to connect the hanging rod member and the pull-out member. To provide a cross connector which can be easily and quickly cross-connected with a rod-like member by a one-touch engagement operation, and can arbitrarily select the crossing angle, and which can be widely used not only for crossing rod-shaped members. The purpose is to

An embodiment of this invention will be described below with reference to the drawings.

Reference numeral 1 shown in the figure is a metal fitting main plate disposed at the intersection of a pair of rod-shaped members B1 and B2 that intersect with each other, and is made of a highly elastic plate material such as spring steel. The front is rectangular, and the sides are omitted.
It has an arcuate shape. When the metal fitting main plate 1 is curved against the elasticity of the metal fitting main plate 1 in the vicinity of both ends in the longitudinal direction, a punching member B1 as one rod-shaped member is formed.
is penetrated and the metal fitting main plate 1 attempts to return to its original state.
A mounting portion 2 having an inner circumferential edge surface 2A that comes into pressure contact with the mounting portion 2 is provided. In addition, numerals 3 in the figure are tabs provided at both ends to curve the main plate 1 itself.

The attachment part 2 only needs to be formed in the shape of a hole having a size sufficient for the punching member B1 to be inserted therethrough, considering that it is attached to the punching member B1. It must be inserted from the end and moved to the cross-support position. Therefore, in the illustrated example, the mounting portion 2 is communicated with the outside through notches formed from the side edges near both ends of the main plate 1 of the metal fitting. It can be directly attached to a desired position without moving it along the length of B1, which simplifies the installation work and is particularly effective when both ends of B1 are connected to other members. Become.

Therefore, the shape of the mounting part 2 shown in the figure is different from that of the main plate 1 of the metal fitting.
It is formed into a rectangular shape that communicates with the outside at the side edges, and the edge surface of the free end of the main plate 1 is connected to the mounting part 2.
It has a stepped shape that becomes wider as it reaches the back edge. By making it step-like, the parts 1 that intersect with each other
When the diameter of the punching member B1, which is inserted into the mounting portion 2, is different in size, the mounting Since the position can be selected depending on the size of the width interval obtained between the center side edge surface of the metal fitting main plate 1 in the section 2, it is possible to increase the compatibility. In addition, the removal member B1
When the diameter is large, the corner part of the stepped edge almost bites into the circumferential surface of the punching member B1 to securely lock it, and furthermore, if the punching member B1 has a thread, The step edges can be threaded together to provide a more secure locking condition (see FIG. 5).

A cross-support plate 5 having a generally groove-shaped cross section is rotatably connected to a flat plate-shaped connecting portion 4 provided approximately at the center of the main plate 1 of the metal fitting. This cross support plate 5 has a support groove 7 on the side wall which has a V-shaped edge surface 7A that fits into a hanging rod member B2 such as a hanging bolt or reinforcing bar as the other rod-like member that intersects with the hollow member B1 as one rod-like member. A notch is formed in 6, and the deep wall 8
and connection holes 9 and 10 opened in each of the connection parts 4.
The pin member 11 inserted through the metal fitting main plate 1 is connected to the metal fitting main plate 1 so as to be able to rotate relative to the metal fitting main plate 1. In particular, as shown in FIG. 1, the connection state is such that the groove direction of the cross support plate 5 is approximately aligned with the length direction of the main plate 1, so that the mounting portion 2 of the main plate 1 is connected. The supporting member B1 and the hanging rod member B2 supported by the support groove 7 of the cross support plate 5 can be connected at a predetermined cross angle.

As shown in FIGS. 1 and 6, the cutout shape of the support groove 7 is such that the end edge of the side wall 6 becomes a parallel edge 7B, and
The inner wall 8 forms the V-shaped edge surface 7A.
Due to this shape, the gap between the parallel edges 7B allows the hanging rod member B2 to fit very well, and is useful for further improving the crossing stability. Of course, the support groove 7 may have only the V-shaped edge surface 7A (not shown).

This invention is constructed as described above, and as shown in FIGS. 2 and 3, for example, electrical equipment materials D such as lightweight channel steel materials for piping conduit pipes P and other pipe materials are suspended from ceiling slabs S. For example, when supporting
Here's how to use it: That is, the suspension member B1 is installed between the hanging rod members B2 and B2 from the ceiling slab S, and the suspension members B1 and B2 are
To use this devised metal fitting at the intersection of
2 are fitted, and the cross support plate 5 is abutted against this B2, and the punching member B1 is placed inside the mounting part 2 of the metal fitting main plate 1, and then The applied pressing force is released, and the elastic return force generated at that time causes both B1,
B2 cross-links each other. that time,
Depending on usage conditions at the installation site, etc., hanging rod member B
The intersecting angle of the cutting member B1 with respect to 2 can be arbitrarily selected, and it may be in an inclined state as shown in FIG. 2, or it may be in a perpendicular state as shown in FIG. 3. It is something.

In the figure, one rod-shaped member B2 is attached to the support groove 7 of the cross support plate 5, and the other rod-shaped member B1 is attached to the attachment part 2 of the main plate 1. Although each is supported, the same effect can be obtained by reversing this support (not shown).

Therefore, by installing a hollow member B1 that intersects with the hanging rod members B2 between the plurality of hanging rod members B2 suspended from the ceiling slab S, etc., the light weight supported by the hanging rod members B2 It is possible to reliably prevent various electrical equipment materials D such as channel steel materials from shaking, and it is possible to greatly improve safety during and after construction.

When the metal fitting main plate 1 is subjected to an elastic restoring force to return to its original state due to its own elastic force, the inner circumferential edge surface 2A of the mounting portion 2 is pressed against one of the rod-shaped members B1, and at that time, Since the inner circumferential edge surface 2A is press-fitted into the surface of the rod-shaped member B1 in a substantially bite-like manner, the metal fitting main plate 1 is firmly fixed to the rod-shaped member B1. Also,
Not only can the support position be arbitrarily selected, but even if the elastic return force is limited even after support, the cross support plate 5 is connected to approximately the center of the main plate 1 of the metal fitting, and the bending operation of the main plate 1 of the metal fitting is easily controlled. Coupled with the fact that it does not get in the way, the support position can be changed freely, cross-connection work is simple, and it can be safely constructed even at high places.

On the other hand, the cross-support plate 5 connected to the approximate center of the main plate 1 has a substantially groove-shaped cross section with a support groove 7 cut out in the side wall 6 and having a V-shaped edge surface 7A that fits into the other rod-shaped member B2. Therefore, the rod-shaped member B2 is firmly supported, and the V-shaped edge surface 7A supports the rod-shaped member B2.
Even if the diameter of the rod-shaped member B2 is changed to be large or small, it can be accommodated.Furthermore, if the rod-shaped member B2 has a screw thread, the V-shaped edge surface 7A is connected in a screw-like manner, and this V-shaped edge surface 7A By having these on both side walls 6, it is possible to achieve an even more solid support state.

In addition, since the cross support plate 5 is rotatably connected to the flat connecting portion 4 at its inner bottom wall 8, the rod-like member B can be rotated by selecting the rotation angle.
It is possible to deal with changes in the intersecting angle between B1 and B2, and for example, as shown in FIG. 2, cross-connecting in an inclined state is more effective in preventing shaking. In addition, when mounting and connecting one rod-shaped member B1 between a plurality of rod-shaped members B2, first, cross-connect them at one place to temporarily connect them,
It can be adjusted to match the predetermined intersection angle when cross-connecting at other locations, and the connection work can be speeded up.

As explained above, according to this invention, it is possible to connect and support the rod-like members at an appropriate intersecting angle, and the intersecting position can be arbitrarily selected, and there is no need to perform special processing on any of the rod-like members. In addition, since the connection and support work is performed in a one-touch manner using the elastic restoring force of the main plate of the metal fittings, it is safe even when working at high places, and even after cross-connection, there is no possibility of external interference. It is stable and will not separate or fall off even when subjected to shock or vibration.
Furthermore, the crossing position after cross-connection can be freely changed, the load resistance is excellent, and the structure is simple and can be provided at low cost, which is extremely useful in practice.
