Problems solved by technology
like figure 1 As shown, the normal cable tray is a straight trough structure. The traditional installation of arc cable trays generally uses arc-shaped corner elbows directly purchased from the manufacturer, and then the straight section of the bridge and the corner elbow are assembled on site. This method is costly; One method is to use the straight section of the bridge to process the corners on site. The operation process is complicated and the project quality is not easy to guarantee

Embodiment Construction
[0027] Such as figure 1 As shown, the structure at the junction of two straight cable tray units 1, 3 is fixed by direct pieces 2, 4 and bolts on both sides.
[0028] When it is necessary to install cable trays in buildings with arcs, such as figure 2 , 7 As shown, the arc-shaped direction can be decomposed into several straight cable tray units connected end to end.
[0029] In this way, the shape of the building structure can be measured first, and the position and path of the bridge laying can be compared with the structural diagram to find out the corner points corresponding to the shape of the bridge and the arc structure. Generally, the arc structure is composed of multiple straight ring beams, and the corner point is generally the joint of two straight beams, that is, the intersection point of the meridian axis and the weft axis, and the corner angle is obtained by calculation. Analyze and count the number and angle of each corner to determine the number of straight...

The invention relates to a cable tray and an installation method of the cable tray, in particular to the installation method of the arc cable tray, which solves the problem of installation of the cable tray in an arc building. The cable tray comprises straight cable tray units and a direct connecting piece. The installation method comprises first measuring radian at the turning of the building; second processing the direct connecting piece to obtain a corner outer side connecting piece and a corner inner side connecting piece; third arranging a bottom supporting plate at the position of a triangular space at the connecting position of adjacent straight cable tray units; respectively clamping the corner outer side connecting piece and the corner inner side connecting piece on the outer side and the inner side of a corner; installing a lining plate at the position of the corner; arranging bolt gaskets on the outer sides of the corner outer side connecting piece and the corner inner side connecting piece; and finally enabling the connecting pieces, the lining plate, the cable tray units and the bolt gaskets to be connected through bolts. Therefore, the arc cable tray is formed by connecting a plurality of cable trays.
Description
technical field [0001] The patent of the invention relates to a cable bridge and its installation method, specifically a method for installing an arc-shaped cable bridge. Background technique [0002] The cable tray is an important device in the wiring engineering in the building, which is used to place and guide the building cables. With the continuous development of the city, while meeting the functional requirements of the building, the requirements for the appearance of the building are constantly improving, and a large number of buildings with various curved structures appear. In a building of this shape, the direction of the cable can only be set along the arc, so the cable tray is also required to be made into an arc. Such as figure 1 As shown, the normal cable tray is a straight trough structure. The traditional installation of arc cable trays generally uses arc-shaped corner elbows directly purchased from the manufacturer, and then the straight section of the brid...
