Embodiment Construction
[0041] An arc-shaped cable trough structure, comprising a horizontally installed cable trough and a trough support member arranged along the position of the cable trough, the cable trough includes two straight line troughs and an arc segment connecting the two wireway, see Figure 5-6 As mentioned above, the arc-segment line slot is groove-shaped and includes two connection units 1 with the same shape and size. The two connection units are mirrored on the left and right, and each connection unit includes a bottom plate and a vertical bottom plate located at both ends of the bottom plate 2 respectively. The long-side slot 3 and the short-side slot 4,
[0042] The long-side grooves 3 and the short-side grooves 4 are both rectangular, the long-side grooves and the short-side grooves have different lengths and the same height, the bottom plate 2 is a right-angled trapezoid, and the upper bottom is connected with the short-side grooves, The lower bottom is connected with the long ...

The invention discloses a construction method of an arc cable wire slot structure. The arc cable wire slot structure comprises a cable wire slot and a wire slot bearing part, wherein the cable wire slot comprises two segments of linear wire slots and an arc wire slot for connecting the two sections of linear wire slots; the arc segment wire slot is slot-shaped and comprises two connecting units with the same shape and size; two connecting units are in left-right mirroring butt joint, each connecting unit comprises a bottom plate, and a long ledge and a short ledge which are respectively vertical to the bottom plate. The construction method comprises the steps of computing the bend angle of the arc segment wire slot, counting the angle and the type of the arc segment wire slot, drawing a blank part detail drawing by using the 3D software, processing to produce the arc segment wire slot and numbering, paying off according to the mounting of a wire slot support by a design drawing, and mounting the wire slot. The construction method can satisfy the demand of the rigid cable wire slot mounting when the municipal integrated trench construction arc structure part is high in occupancy, the arc wire slot is multiple in specification and model, the cable laying quality requirement is high, and the mounting space arrangement difficulty is large.
Description
technical field [0001] The invention relates to a construction method for a cable trunking by using a building information model (BIM). Background technique [0002] With the increase of various special-shaped building structures, in the installation of electrical equipment, the arc-shaped trunking increases accordingly. The traditional construction process of arc-shaped trunking adopts on-site manual production, which increases labor intensity, reduces work efficiency, wastes materials, and cannot guarantee installation accuracy and quality. Check the catalogue of galvanized fireproof cable trunking products, there are no curved cable trunking products, only straight sections and accessories such as straight-through, two-way, three-way, four-way and so on. In the past construction, in order to solve the installation of the arc cable trunking, the construction technology of cutting, corner splicing and horizontal plugging is generally used to solve the problem. This proces...
