  According to the cable laying cleat of the present invention, the supporting member that supports the cable is installed on the laying surface with the first connecting portion coupled to the second connecting portion of the position adjusting member. At this time, since the support member can be disposed at any position of the position adjustment member, the position of the cable to be laid can be freely determined. In addition, since a plurality of support members can be freely arranged on one position adjustment member, the interval between adjacent cables can be freely set. Furthermore, since a plurality of support members having different cable receiving portion shapes can be used in combination with one position adjusting member, the types of members necessary for laying a plurality of cables can be reduced. No processing or the like is required. As described above, according to the cable laying cleat of the present invention, it is possible to give a degree of freedom to the position, interval and combination of the cables to be laid, and to efficiently carry out the cable laying work with fewer kinds of members.

  It is preferable that the first connecting portion includes one or a plurality of convex portions, and the second connecting portion includes a plurality of concave portions that are arranged at a predetermined interval and are fitted and coupled to the convex portions. . With this configuration, the convex portion of the support member can be coupled to the concave portion selected in accordance with the laying position of the cable from among the plurality of concave portions arranged on the position adjusting member. Thereby, the connection mechanism of the 1st connection part and the 2nd connection part can be simply constituted so that a degree of freedom may be given to the position, interval, and combination of the cable to be laid.

  Moreover, it is preferable that the said recessed part is formed with the through-hole which can connect the said convex part also from the laying surface side of the said position adjustment member. Thereby, the position adjusting member can be used without distinguishing the front surface and the back surface.

  Preferably, the support member is formed such that a cross section of the cable receiving portion is formed by dividing the cross section of the cable into two, and the cable is supported between a pair of support members having the same shape of the cable receiving portion. . Accordingly, the cable to be laid can be supported by being sandwiched from above and below, for example, using a pair of support members. Furthermore, when the recess is a through-hole, another position adjusting member is arranged on the supporting member that supports the cable from above, and another supporting member is arranged on the position adjusting member. A plurality of cables can be laid over many stages.

  The pair of support members preferably have engagement portions that engage with each other when the cable is supported between the two cable receiving portions. As a result, two support members sandwiching one cable from two opposite directions can be overlapped and held, and in particular, when laying a plurality of cables over many stages, Stability can be improved.

  As shown in FIG. 1, a cable laying cleat according to an embodiment includes a support member 1 that supports a cable C to be laid and a position adjustment member for installing the support member 1 on an installation surface W so that the position of the support member 1 can be adjusted. 2 is provided.

  The support member 1 is a synthetic resin member used by being coupled to the position adjustment member 2, and has a plurality of convex portions 11 as first connection portions on the position adjustment member 2 side. The convex portions 11 are arranged at a constant interval (for example, an interval of 3 cm), and the shape thereof is cylindrical.

  Further, the support member 1 has a cable receiving portion 12 that receives the cable C, and the shape thereof is formed by dividing the cross-sectional shape of the cable C into two. For example, as shown in FIG. 1, when the cross section of the cable C is circular, the shape of the cable receiving portion 12 is a semicircular shape corresponding to the radius of the cable C.

  The position adjusting member 2 is a plate made of synthetic resin that is installed on the laying surface W, and has a plurality of recesses 21 as second connection portions. Each concave portion 21 is a through hole into which the convex portion 11 can be fitted, and is provided at the same constant interval (for example, 3 cm interval) as the arrangement of the convex portions 11. Since the concave portion 21 is a through-hole, the position adjusting member 2 can couple the convex portion 11 from both sides without distinguishing the front surface and the back surface, and the thickness thereof can be combined with the convex portion 11 at the same time. The protrusion width of the convex portion 11 is larger than twice.

  Further, the position adjusting member 2 may be prepared in various sizes so as to correspond to the size and the number of the supporting members 1 arranged on the position adjusting member 2, but the breaking portion that runs vertically and horizontally between the recesses 11. And may be configured so that it can be processed into a desired size at the cable installation site.

  Next, a method for using the cable laying cleat of this embodiment will be described.

  As shown in FIG. 2, the worker who performs the laying operation of the cable C first installs the position adjusting member 2 on the laying surface W where the cable C is laid.
