Description

[Detailed explanation of the invention] This invention relates to an assembly type branching cable rack.
When storing and wiring cables in a factory or other building structure, use an X-shaped plane at the branch or confluence point.
When connecting a straight cable rack to a T-shape, etc.,
The present invention relates to an assembly type branching cable rack that can be easily and quickly assembled into an X-shaped or T-shaped planar shape at a cable installation site, and provides various advantages in manufacturing and transportation.

When branching or merging cable racks, pre-assemble cable racks with X-shaped or T-shaped planar shapes for branching, and transport them to the installation site to connect straight cables. It was interconnected with the rack.

However, in this case, the branch cable rack is assembled at the factory, transported, and delivered in the same form as it is laid, so the final process of manufacturing, such as plating, storage, and transportation, is required. All of these methods require large-sized equipment, and the products themselves are bulky, making these operations extremely troublesome and difficult.

For example, in the method disclosed in Japanese Unexamined Patent Publication No. 139992/1983, the cable support space becomes large because the cross member is arranged in an X-shape at the branch path, and the cable support lacks stability.
The method disclosed in Japanese Unexamined Patent Publication No. 527-129997 has the same drawbacks because the connecting plates are similarly arranged in an X-shape, and the construction structure of the connecting plates is fragile because it is based on bolt shafts. The method disclosed in Japanese Utility Model Publication No. 5454920 has the various drawbacks mentioned above because it cannot be disassembled into child and parent girders.
Since the bottom itself was disk-shaped, it could not be made compact even if it was disassembled.

Therefore, this invention was devised in order to eliminate the above-mentioned conventional drawbacks, and its gist is that it is a branching system that connects cable racks that store and route cables inside in a ten-sided approximately X-shape or T-shape. In a cable rack, the opposing main girders in the branching paths to be connected are widened at the connecting center and narrowed at the connecting ends, so that the central part is shaped like a planar arc, and the end The parts are formed into a straight plane shape, and long child girders are installed between the main girders at the connection center, and short child girders are installed between the main girders at the connection ends, and the side parts of the long child girders are installed between the main girders at the connection ends. A socket body having a groove-shaped cross section is provided to protrude orthogonally from the other long spar or the linear portion of the main spar side, which is disposed on the side of the long spar, and on the side of the main spar. Between the opposing socket bodies, a sub-spar member having a cross-sectional groove shape in which the socket body is housed is installed via a fastening member, and can be assembled freely, and the sub-spar member has a locking piece at its open end. a parallelogram-shaped engagement plate, the fastening member being rotatable by being inserted into the child spar member from the gap between the locking ends; It consists of a pressing screw that presses the engagement plate itself against the locking piece when the engagement plate is screwed into the locking plate and the tip is fitted onto the socket body surface.

Hereinafter, embodiments of this invention will be described with reference to the drawings.

The reference numeral 1A shown in the figure is a main girder facing each other of a cable rack in which cables W are housed and routed, and is configured in a planar approximately X-shape so as to be connected from four directions, or in a T-shape. It is formed in a shape suitable for being positioned at a branch path portion to be connected in a branch cable rack so as to be connected from three directions.

In other words, the mutual widths at the connection center, which is the center of branching or merging, are widened, and the mutual widths at the connection ends are narrowed, so that the central part is formed into a planar arc shape and the end portions are formed into a planar straight shape. The cross section thereof is formed in the shape of a groove.

At this time, in consideration of reinforcing the main girder 1A itself, as shown in the figure, the center in the height direction is recessed inward in a groove shape, so that the overall cross-sectional shape is approximately bow-shaped. It is extremely preferable to leave the socket body 4 and the child beam member 5 together, and by utilizing the recess on the lower side, as will be described later, it is possible to further improve the stability of the connection with both the socket body 4 and the child beam member 5.

As shown in the figure, the end portion of the main girder 1A is straight so that other straight cable racks (not shown) are connected to each branch.
The central portion is arcuate to allow the cables W to branch and merge in different directions smoothly.

And, between the parent girders 1A facing each other, the long child girders 2 are arranged such that their connecting centers are continuous with the straight line portions, and the long child girders 2 are perpendicular to the straight line portions at the connecting ends. By erecting the short beams 3, the main beams 1A are integrated with each other via the child beams 2 and 3, thereby forming a branch path member.

At that time, as shown in Fig. 1, if it is planned to have a planar approximately X-shaped configuration, a pair of parent girders 1A, each child girder 2
, 3 are arranged symmetrically, with the elongated crossbeams 2 facing each other, and as shown in FIG. If it is planned that the branch path member beam will be used as a branching path member, a straight master beam 1B disposed opposite to the elongated support beam 2 will be used.

4 denotes the side part of the long beam 2 in the branching path member, and the side part of the long beam 2 or linear master beam 1B of the other branching path member disposed opposite to this 2 on the side of this long beam 2. and socket bodies protruding orthogonally at opposing positions.

This socket body 4 itself is adapted to a fastening means using a fastening member 6 that connects and fixes the socket bodies 4 and 5 to each other in order to erect the child beam member 5 having a groove-shaped cross section by inserting the socket body 4 between the opposing socket bodies 4. Correspondingly, the cross section is formed in the shape of a groove in order to securely connect it to the child beam member 5.

The illustrated socket body 4 has a substantially groove-shaped cross section with an open upper side, and the elongated spar 2
The socket body 4 is attached to the long child girder 2 and further to the main girder 1A so that the upper surfaces of the child girder members 5 which are assembled via the short child girder 3 and the socket body 4 are set at the same height.
is combined with

In particular, in order to stably support the cable W, when the child girder members 5 are installed between the long girders 2 or between the long child girders 2 and the main girder 1B, the From the upper part of the side recess to the lower part of the central recess,
The upper part of the base end of the socket body 4 is sandwiched in a lateral curvature shape.

As described above, the sub-girder member 5 is formed to have a groove shape in cross section so that the socket body 4 can be installed therein, and its arrangement is such that the lower side is usually opened in order to ensure the placement and support of the cable W. It will be erected.

The fastening member 6 is adapted to erect the child beam member 5, which is formed into a substantially groove-shaped cross section with a locking piece 7 along its open end, and from the gap between the ends of the locking piece 7. A parallelogram-shaped engagement plate 8 is inserted into the child beam member 5 and is rotatable. 8 itself with the locking piece 7
It is removed from the press screw 9 which is pressed into contact with the press screw 9.

According to this, as the pressing screw 9 is rotated and screwed in, the child spar member 5 gradually protrudes toward the inner side surface of the upper bottom wall of the child spar member 5, and when it reaches 4,000 faces of the socket body, the child spar member 5 itself is pushed down, and at the same time, the inner surface of the upper bottom wall is pressed against the upper surface of the socket body 4, and the engagement plate 8 is pressed against the locking piece 7, so that the fastening member 6 is connected in a tensioned manner within the child beam member 5. Therefore, the child spar member 5 is connected to the long child spar 2 through the fastening member 6.
Furthermore, it is fixed to the parent digits IA and IB.

At this time, as shown in FIG.
Since it is formed into a parallelogram shape that is inserted into the child beam member 5 through the gap between the ends and is rotatable, it is convenient because it can be directly installed at the fastening position, and the work efficiency is improved. In addition, since there are no protrusions on the sub-girder member 5, there is no risk of damaging the cable W.

Furthermore, the cross-sectional shape of the child beam member 5 may be a "] shape as shown in FIGS. 3 to 5, or a [] shape as shown in FIG. 7.
It is possible to adopt any shape, whether it is a round shape as shown in FIG.

This invention is constructed as described above, and when it is used next, depending on the wiring situation of the cable W at the installation site, if the cable W is to be branched or merged in a planar approximately X-shape, as shown in FIG. A pair of branch channel members consisting of a pair of parent girder 1, long child girder 2, and short child girder 3 is also used, and this is assembled by fastening this to the socket body 4 with a plurality of child girder members 5. Yes, when branching and merging into a roughly T-shaped planar shape,
As shown in FIG. 2, the assembly is performed by using one branching path member and fastening it to the socket body 4 with a plurality of child girder members 5 between it and the opposing straight main girder 1B. be.

Therefore, it can be assembled at the installation site, and since it is in a compact form that has been partially assembled beforehand, it is suitable for both plating, storage, transportation, etc., which is the final process during production at the factory. However, the equipment can be small, easy to handle, and work efficiency can be greatly improved.

Moreover, the main girders 1A facing each other in the branch road have a wide mutual width at the connecting center and a narrow mutual width at the connecting ends, so that the central part has a planar arc shape and the end part has a flat surface. Since it is formed in a straight line, it is extremely smooth to connect with linear cable racks that are connected to branch or merge, and to change the wiring direction of the cable W. , together with the short stringer 3, it has a structure that is robust against external shocks and vibrations.

The side part of the long child girder 2 installed between the main girders 1 with the connection center, and the side part of the other long child girder 2 or main girder 1B, which is arranged opposite to this long child girder 2 on the side of this long child girder 2. Socket bodies 4 are protruded from each other at positions facing each other, and the child girder member 5 is constructed between the socket bodies 4, so that the cable W can be supported for wiring along the long child girder 2 or the main girder 1B. is reliable, and since both the sub-girder member 5 and the socket body 4 have a groove-shaped cross section, they are stable without being distorted by the load.

Since the sub-girder member 5 is installed between the socket bodies 4 via the fastening member 6 with the socket body 4 installed inside, the sheath of the cable W passed on the sub-girder member 5 is covered with the socket body 4. There is very little risk of damage caused by this, and it is safe.

In addition, not only can they be stored and transported separately as the main girder 1A with the socket body 4 and the child girder member 5, but also
Since the socket body 4 protrudes perpendicularly to the linear portions of the long child girder 2 and the parent girders 1A and IB, the child girder 3 that is erected and supported by the socket body 4 is Digit IA, I
It is perpendicular to the linear portion of B, which stabilizes the support for pulling in the cable W to be passed through, and increases the overall robustness after assembly.

As explained above, according to this invention, it is possible to select either a roughly X-shaped planar shape or a T-shaped planar shape depending on the wiring situation at the installation site, and to assemble the cable by connecting it with a straight cable rack. It is possible to quickly branch and merge the cables stored in the wiring, and it is also possible to disassemble or assemble each component, so it can be packed compactly and not bulky during production, storage, and transportation. It is convenient because it can be easily assembled, and once assembled, it is extremely sturdy without being distorted or disassembled, can sufficiently support the weight of the cable being routed, and is extremely practical as it is simple in construction and can be provided at low cost. It has the following effects.
