Abstract

The utility model provides a connecting piece of a branch pipe of a cable trough. The connecting piece is connected with a cable trough. The connecting piece is formed by the connection between a branch pipe connecting box which is in bridge joint with the upper part of the cable trough and a bearing groove which is in bridge joint with the lower part of the cable trough in a fastening way; the left side wall and the right side wall of the branch pipe connecting box are correspondingly provided with at least one pair of pipe penetrating holes, the bottom surface of the branch pipe connecting box is glued to the upper surface of the cable trough, the left side wall and the right side wall of the branch pipe connecting box are downwards extended to be provided with two packing walls, the two packing walls are glued to the two side faces of the cable trough, the edges of the two packing walls are provided with a plurality of squarely-bended flange edges, the flange edges are provided with a plurality of connecting holes, and a flange edge of the bearing groove is combined with a flange edge of the branch pipe connecting box to be fixedly connected with each other by the means that a plurality of screw bolts are penetrated through the connecting holes. As the position which is connected with the branch pipe is changed from the side face of the cable through to be above the cable through, so that the connecting piece saves the space of a suspended ceiling, leads the arrangement of the suspended ceiling to be more flexible, leads the pavement of the cable to be more beautiful, effectively solves the problem that the branch pipe can not be connected when the cable trough is arranged at high density, and is particularly suitable for the condition that the plurality of cable troughs are arranged in a narrow space.

Description

Cable trunking props up pipe connections

Technical field

The utility model relates to a kind of wire casing that cable installation uses and connector of arm built.

Background technology

Along with the development of intelligent building, equipment installation is more and more in the building ceiling void, and the quantity of wire casing also has the trend that significantly increases.Existing method is to adopt reduction furred ceiling absolute altitude, increase width of corridor, raising individual layer floor height to satisfy the demand that equipment installation lays.Existing cable trunking mounting means mainly contains following three kinds:

1, consider that wire casing connects arm, a groove requisite space after, wire casing same horizontal absolute altitude spacing big (〉=150mm) lay.This is a kind of very convenient and the most commonly used wire casing system of laying, and its advantage is that vertical direction is saved the space, easy construction, and it is bigger that shortcoming is that horizontal direction takes up space.When possessing, generally adopt this scheme, referring to shown in Figure 1 as field condition.

2, after the consideration wire casing connect arm, a groove requisite space, absolute altitude improved the 50mm installation successively at the bottom of the wire casing.Be the wire casing system of laying of taking when condition suffers restraints at the scene, its advantage is that horizontal direction is comparatively saved the space.Shortcoming is that vertical closeness is poor, and step takies after laying in the vertical space that vertical space makes wire casing lay and can't pass other pipelines, influences the utilization of overall space, referring to shown in Figure 2.

3, no matter all be subjected under the situation of serious constraint at the scene at vertical space or horizontal space, lay for satisfying wire casing, in work progress, may the various situation of each professional pipeline appear at local location generally, propose wire casing not considering that wire casing connects on the basis of arm, groove " high density " lay (level interval 50mm), wait to pass behind the various zone of pipeline an arm or a groove again.As Fig. 3, each professional pipeline of A place is various among Fig. 4, wire casing " high density " can be laid that (horizontal space does not satisfy " with high; big spacing " and lays requirement, vertical space does not satisfy " step " when laying), by the time behind the comparatively loose B place, wire casing is variable to be changed to " with high; big spacing " lays (horizontal space satisfy lays " with high; big spacing " when requiring) or " step is laid " (horizontal space does not satisfy " with high; big spacing " and lays requirement, vertical space can satisfy " step " when laying), but when the wire casing high density was laid, the installing space of arm utilized problem, problem such as be artistically decorated all has to be solved.The wire casing high density is laid form, referring to Fig. 3, shown in Figure 4.

Summary of the invention

The purpose of this utility model provides a kind of cable trunking and props up pipe connections, the space utilization problem when wire casing is connected with arm in the time of solving the wire casing high density and lay.

For achieving the above object, the utility model adopts following technical scheme:

This cable trunking props up pipe connections, is connected with cable trunking, and the support groove under cable trunking is fastened and connected and forms in arm connecting box on the cable trunking and cross-over connection by cross-over connection for it;

Described arm connecting box has at least one pair of poling hole in left and right sides wall correspondence, the bottom surface length of arm connecting box is identical with the width of cable trunking, the bottom surface of arm connecting box be attached to cable trunking above, the left and right sides wall of arm connecting box extends two bag walls downwards, two bag walls are attached to the two sides of cable trunking, two bag mural margins have the flange of rectangular bending, have connecting hole on the flange;

The length of described support groove is identical with the length of arm connecting box, the opening of support groove up, its groove bottom is attached to the bottom surface of cable trunking, its two ledge is attached to the two sides of cable trunking, also there is the flange of rectangular bending at the edge of two ledges, the flange of the flange of support groove and arm connecting box and together, it is fixedly connected to pass connecting hole by bolt.

The left and right sides wall of described arm connecting box is vertical with the bottom surface or be trapezoidal symmetric arrangement.

Have ground hole on the flange of described support groove, on the flange of arm connecting box lower end also correspondence have ground hole.

Described poling hole is pre-manufactured hole or on-the-spot knock down hole.　

Compared with prior art the utlity model has following characteristics and beneficial effect:

Cable trunking props up pipe connections can satisfy wire casing and closely arrange time wire casing is connected with arm.The wire casing top is changed into by the side of wire casing in the position that connects arm, has saved the ceiling void, and it is more flexible to make furred ceiling arrange, and it is more attractive in appearance that cable is laid, and can satisfy the requirement of cable radius of turn.Prop up pipe connections and can satisfy the equipotential connection request, security measure puts in place, and is safe and reliable.

The utility model efficiently solves when the wire casing high density is laid can't connect the arm problem, is specially adapted to the be laid in situation of small space of many times wire casings.
