DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the connection structure and the connection member of the wiring / pipe receiver according to the present invention will be described in more detail with reference to examples. The present invention is not limited by the following examples unless the gist is exceeded.

As shown in FIG. 1, a connection structure 100 and a connection member 40 for a wiring and piping receiver according to an embodiment of the present invention.
The engaging portion 31 of the connecting member 30 is engaged with the engaging portion 21 formed on the outer surface of the parent girder 20a, b as the side wall 20a, b according to the claims of the two wiring and piping receivers 10a, b. The pressing screw 3 which is engaged and screwed into the connecting tool 30 so as to be able to advance and retreat.
2 is the pressed surface 22a of the master girder 20a of one of the receiving members 10a.
To fix the receiving member 10a to the connecting member 30 and make the other receiving member 10b slidable in the longitudinal direction in the engaged state. To prevent disengagement of
One of the receiving members 10a and the other receiving member 10b are connected by a connecting member 40 to form a basic configuration.

The receiver 10a has two main girders 20a formed of a plate material of aluminum or the like having a constant cross section and arranged at a predetermined interval, and a plurality of small girders 50 are erected between the main girders 20a. Thus, the whole is formed in a lattice shape.
Note that the wiring and piping receiver used in the connection structure of the wiring and piping receiver according to each of the present invention is not limited to the wiring and piping receiver formed in the lattice shape. The receiving member for wiring and piping formed in a shape may be used, and is not particularly limited.

The main beam 20a constituting the receiving member 10a
As shown in FIG. 2, a hook-shaped locking portion 21 which is opened downward in the longitudinal direction is formed on the outside thereof in three stages, and the connecting tool 30 is adapted to correspond to the locking portion 21. A hook-shaped engaging portion 31 which is opened upward is formed on the upper surface, and is configured to be engaged with the engaging portion 31.

As shown in FIG. 1 or FIG. 2, a plurality of screw holes 34 inclined downward are formed at the upper end of the connecting member 30. In the screw hole 34, a pressing screw 32 that is pressed into the pressed surface 22 a of the parent girder 20 a of one receiving tool 10 a and is screwed in, and the contact surface 2 of the parent girder 20 b of the other receiving tool 10 b are screwed.
The contact screws 32 screwed into contact with 2b are respectively screwed. In this embodiment, the parent girder 20 is used.
The outer surface of “a” is shown as the pressed surface 22a, and the outer surface of the parent girder 20b is shown as the abutted surface 22b.

Then, as in this embodiment, the adjacent parent digit 2
The engagement portions 31 formed on the coupling tool 30 by applying the coupling tool 30 from the lower side between the pair
It is designed to be able to engage with the locking portions 21 formed on the parts a and b. As described above, when the locking portion 21 and the engaging portion 31 are engaged with each other, the locking portion 21 and the engaging portion 31 are regulated in two directions, that is, the upward direction and the lateral direction. Therefore, in order to fix one of the receiving members 10a to the connecting portion 30,
The pressing screw 32 is screwed into the screw hole 34 so that the tip is
If the pressing force is applied so as to squeeze against the pressed surface 22a of 0a, the force due to the reaction is dispersed in two directions, so that the connecting portion of the receiving member 10a is prevented from rattling and connected at the same time.

When the contact screw 33 is screwed into the screw hole 34 and tightened, the other end of the receiving member 10b contacts the contact surface 22b of the master girder 20b. 30 is slidable in the longitudinal direction with the engagement maintained. In other words, even if the abutment screw 33 is screwed into the screw hole 34 and tightened, the tip of the abutment surface 22b of the receiving device 10b is pressed instead of pressing the receiving surface 22b. Without being fixed to the connector 3
It is possible to slide with the engagement maintained at zero. Therefore, as shown in FIG. 1, the length of the shaft of the contact screw 33 is slightly shorter than the length of the shaft of the pressing screw 32.

As shown in FIG. 3 or 4, the other receiving member 10b may be slidable by using a disengagement preventing member 35 formed in a substantially U-shape. It is not limited to the slidable state by the contact screw 33 as long as the slidable state is such that the other receiving tool 10b is kept engaged with the connecting tool 30. Anything is fine.

The disengagement preventive device 35 is connected to the contact surface 22b of the main girder 20b so as to grip the connector 30.
0, and a pressing screw 37 is screwed into a screw hole 36 formed in the disengagement preventing device 35.
It is integrally fixed to 0. As a result, the other receiving member 10b can slide in the longitudinal direction while being engaged with the connecting member 30.

Next, a connecting member 40 for connecting the one receiving member 10a and the other receiving member 10b to prevent the engagement of the other receiving member 10b from being released will be described.

The connecting member 40 is, as shown in FIG.
It is erected between the child girder 50 of one receiving member 10a and the child girder 50 of the other receiving member 10b. Thus, the other receiving tool 1 slidably engaged with the connecting tool 30.
0b can maintain the engaged state without detaching from the coupling tool 30. Therefore, the other receiving device 10
b can slide in the longitudinal direction while maintaining the engaged state from the coupling tool 30.

The shape of the connecting member 40 is formed in a thin plate shape and has flexibility. It is desirable that the material forming the connecting member 40 has little expansion and contraction due to a temperature change or the like. For example, stainless steel, which is a non-insulating material, is preferable. However, according to the gist of the invention, the connecting member 40 needs at least a length capable of bridging the sub-spars 50 in a state where the receiving members 10a and 10b are separated from each other. Therefore, if the length is about the length, it is possible to sufficiently cope with the case where the connecting member 40 is formed of a material such as aluminum. Attachment holes 42 are formed at predetermined intervals in the connecting member 40, and screws 42 are attached to the attachment holes 41.
And forcibly screw it into the groove in which the sub-spar 50 is formed. Thereby, it is firmly and securely attached, and furthermore, since the tip portion of the screw 42 breaks through the insulating coating applied to the sub-girder 50 and comes into contact with the metal part of the sub-girder 50, the connecting member 40 is Receiving fixtures 10a, b
Is electrically connected to the

Since the connecting member 40 has flexibility as described above, the connecting member 40 can be installed in a state of being bent between the sub-spars 50. Receiver 1 utilizing this flexibility
It is possible to cope with expansion and contraction caused by a temperature change of 0a, b and the like.

That is, as one of the various temperature change factors, there is a temperature change due to the change of the four seasons of spring, summer, autumn and winter. For example, when the difference in expansion and contraction when a plurality of receivers are connected to form a laid path is measured from summer to winter or from winter to summer, expansion and contraction of about 14 mm occurs every 9 meters of the laid path. . Therefore, it is preferable to use the connection structure 100 of the wiring / piping receiver according to the present invention at intervals of 9 meters, but it is not particularly limited.

Here, a description will be given of a method of using the connection structure 100 of the wiring and piping receiver according to the present invention.

For example, in the summer, the connection structure 10 of the wiring and piping receiver according to the present invention in a state where the receiver is expanded.
When the receiving members 10a and 10b are connected to each other by using 0, the adjacent receiving members 10a and 10b are connected by the connecting member 30 as shown in FIG. Is provided with bending between the sub-spars. As a result, even when the season shifts from summer to winter and the temperature drops and the receivers 10a and 10b contract, the receivers 10a and 10b maintain the state of being engaged with the coupler 30 as described above. While sliding in the direction of the arrow A shown in the drawing, the portion where the connecting member 40 is bent in response to the sliding returns to the original state. Therefore, as shown in FIG.
Since the receiving members 10a and 10b are separated from each other by the contraction of b, no excessive force is applied to the receiving members 10a and 10b and the connecting member 30 that connects them. still,
Since the distance between the sub-spars differs depending on the type of the receiving member, the location of the mounting hole 41 into which the screw 42 is inserted is not limited to that shown in the above-described embodiment, and may be changed each time.

In the winter, the connecting structure 100 for a wiring and piping receiver according to the present invention in a state where the receiver is contracted.
When the receivers 10a and 10b are connected to each other using
As shown in FIG. 7 or FIG. 8, the receiving members 10a and 10b are connected by the connecting member 30 at a slight interval, and the connecting member 40 is installed without bending. Therefore, when the work is performed in a state where the receiving tool is most contracted in winter, as described above, since the connecting member 40 is erected in a state where the receiving tools 10a and 10b are separated from each other, at least a It is necessary to have a length that can be installed on a vehicle. Thus, even if the season shifts from winter to summer and the temperature rises and the receiving devices 10a and 10b expand, the receiving devices 10a and 10b maintain the state of being engaged with the connecting device 30, and the arrows shown in the drawing. While sliding in the direction B, the connecting member 40 bends in accordance with the sliding. Therefore, as shown in FIG.
Since the receiving members 10a and 10b are brought close to each other by the expansion of the members a and b, meandering due to the expansion of the receiving members 10a and 10b which are connected to each other on the same straight line is prevented.

Next, another embodiment of the connecting member 40 constituting the connecting structure of the wiring and piping receiver according to the present invention will be described with reference to FIG. Note that FIG. 9 shows the construction in a state where the receiving members 10a and 10b are expanded in the summer, like the above-described one shown in FIG. 5 or FIG.

The connecting member 40 is provided between the child girder 50 of the one receiving member 10a and the child girder 50 of the other receiving member 10b, and has a plate-like shape. At both ends, mounting holes are formed. An attachment hole attached to the sub-spar 50 of the other receiving member 10b of the attachment holes has an oval long hole 43 formed therein.
The screw 42 is inserted into the long hole 43 and is forcibly screwed into the groove in which the sub-spar 50 is formed. The screw 42 is screwed into the screw 42 to such an extent that the elongated hole 43 can be relatively moved. As a result, the season shifts from summer to winter, the temperature drops, and the receiver 10a,
b, as described above,
A and b slide in the direction of arrow C while maintaining the state of being engaged with the connecting member 30 and slide within the elongated hole 43 formed in the connecting member 40. Note that, in the winter season, when the work is performed in a contracted state of the receiving device, the mutual receiving device 1 is used in the same manner as in the above-described installation state of FIG. 7 or FIG.
What is necessary is just to connect with the connecting tool 30 at a slight interval between 0a and 0b, and it is clear that the operation and effect are substantially the same.

In the embodiment according to the present invention, the connecting member 40 is formed in a plate shape. However, the present invention is not limited thereto. Anything that prevents the engagement from being released may be used. For example, a member such as a wire may be used.

In this embodiment, the connecting member 40
Is shown between the sub-girder beams, but the present invention is not limited to this, and may be constructed between the parent girder beams.

As described above, the connecting structure 100 and the connecting member 40 of the wiring and piping receiver according to the present invention are formed by the locking portions 21 formed on the outer surfaces of the main beams 20a and 20b of the two receiving members 10a and 10b. The engaging portion 31 of the connecting member 30 is engaged with the pressing member 32, and the pressing screw 32 screwed into the connecting member 30 so as to be able to advance and retreat is pressed against the pressed surface of the parent girder 20a of one receiving member 10a. 10a is fixed to the connecting member 30 and the other receiving member 1
0b is slidable in the longitudinal direction in the engaged state, and in order to prevent the engagement of the other receiving member 10b by the connecting member 30 from being released, one receiving member 10a and the other receiving member 1
0b with a connecting member 40.

Therefore, the other receiving member 10b is connected to the connecting member 30.
