  However, according to the above application structure, the following problem occurs when the number of pipes is large.

  In other words, the former fixed structure that fixes all the pipes as a bundle, the bundle becomes too large to fit in a limited space, or the fixing force is insufficient, especially the inner pipes are displaced. There is a risk of tilting.

  In addition, since piping is fixed together regardless of the system and type, the efficiency of the wiring work deteriorates in situations where it is desirable to fix it separately for each system and type, which is also disadvantageous for maintenance after wiring. It becomes.

  On the other hand, according to the latter split / individual fixing structure, since a large number of metal plates must be installed separately, the use efficiency of the wiring space and the efficiency of the fixing work are deteriorated, and the number of parts is increased and the cost is increased. Become high.

  Therefore, the present invention provides a construction machine wiring that can fix a large number of pipes in an orderly and efficient manner in a limited space and can be firmly fixed, and can improve the efficiency of the wiring work and the subsequent maintenance work. Provide structure.

As means for solving the above-mentioned problems, in the present invention, the routing plate is provided in the left-right direction when the direction perpendicular to the length direction of the piping is defined as the left-right direction in the routing space through which the piping passes. is, this is arranging plate, band passing portion fixing band bundling fixing a bundle of pipes is passed is, at a plurality of locations in the horizontal direction, wiring for passing the pipes between adjacent groups of spaces There spaced so as to partition formed, the pipes are in a state of being divided into a plurality of pairs fixed to the wiring space, as the band guiding part, left and right end portions of the wiring plate A notch-shaped banding groove that opens laterally is provided, and a through-hole-shaped banding hole with a closed periphery is provided at the same front-rear direction position as the banding groove in the middle portion in the left-right direction. those that are That.

  According to this configuration, piping is divided into a plurality of groups, passed through each wiring space, and fixed to the wiring plate, so that a large number of piping is arranged neatly and efficiently in a limited space, Moreover, it can be firmly fixed.

In addition, since the piping can be fixed separately for each system and type, the efficiency of the wiring work and the maintenance after the wiring is improved.
In the present invention, as the banding portion, a notch-shaped banding groove that opens laterally is provided at both left and right ends of the wiring plate, and the same as the banding groove in the middle portion in the left-right direction. A through-hole-like band-through hole with a closed periphery is provided at a position in the front-rear direction.
According to the present invention, the fixing band can be fixed in the front-rear direction by the combination of the groove and the hole, and the banding operation is simplified because one of the grooves is the groove.

In this case, the band passing portion provided at a plurality of locations of the left and right direction, that is provided by a plurality at intervals in the longitudinal direction desired (claim 2).

  In this way, the pipes can be band-fixed at a plurality of positions in the front and back, so that the front and rear positions and directions of the pipes can be determined. it can.

In this case, the hole through the band, that that provided at a plurality of locations preferably in the lateral direction at intervals (claim 3).

  In this way, since the wiring space is formed in at least three in the left-right direction including between the left and right adjacent band through holes, the piping can be more finely grouped and fixed.

  In addition, since the intermediate group of the piping is sandwiched and restrained between the adjacent groups, even if it is configured to be fixed with only one fixing band, it can be reliably fixed with the correct direction. For this reason, the fixing work of piping becomes easy.

On the other hand, between the band through holes adjacent lateral band through the slit of the band through section that opens on one side front and rear, provided in a state in which the wiring space is formed between the band through hole desirably it is (claim 4).

  In this way, the intermediate group of piping is in close contact with the adjacent group, making it difficult to pass the fixed band. However, the banding part on one side is made a slit, so that the banding operation becomes easier.

In addition, it is desirable that the band through hole is provided with a dimension capable of inserting two fixed bands adjacent to the left and right.

In this way, since two adjacent fixing bands can be shared by one band through hole, the fixing operation is further simplified and the length of the routing plate in the left-right direction can be shortened.
In the present invention, the routing plate is provided in the left-right direction when the direction perpendicular to the length direction of the piping is set as the left-right direction in the routing space through which the piping passes. The band passing part through which a fixing band for bundling and fixing a bundle of pipes is passed is formed in a plurality of places in the left and right direction so that an arrangement space for passing the pipes between adjacent ones is defined. Provided at intervals, the pipes are fixed to the wiring space in a state of being divided into a plurality of groups, and the banding portion is provided at a plurality of positions spaced in the left-right direction on the wiring plate. As shown, a through-hole-shaped band through hole with a closed periphery is provided, and between the left and right adjacent band through holes, a band through slit as a band through portion that opens to one side in the front-rear direction is provided in the band through hole. Between the above It provides a routing structure of a construction machine, characterized in that provided in a state where the scan is formed.

  According to the present invention, it is possible to fix a large number of pipes in an orderly and efficient manner in a limited space and firmly, and improve the efficiency of the routing work and the subsequent maintenance work.
