Detailed Description
The features of the present invention and other related features are described in further detail below by way of example with reference to the accompanying drawings, for the understanding of those skilled in the art:
referring to fig. 1-5, the symbols in the figures are: the steel plate bracket comprises a bracket standard knot 1, longitudinal angle steel 1a, a square frame 1b, an inclined strut 1c, an angle steel connecting piece 2, angle steel 2a, a bolt 2b, a steel plate connecting piece 3, a steel plate 3a, a cable groove 4 and a limiting steel bar 5.
Example (b): as shown in fig. 1-5, this embodiment concretely relates to simple and easy light-duty cable tray for bearing cable duct 4, this cable tray mainly forms by 1 concatenations of a plurality of bracket standard festival, and angle steel connecting piece 2 and steel sheet connecting piece 3 have been adopted in the concatenation between the adjacent bracket standard festival 1 to fix.
As shown in fig. 1 to 4, the standard bracket joint 1 in this embodiment is a square column frame structure, 3m is taken as a section, each section weighs 233.3kg, the main frame of the standard bracket joint 1 is composed of five square frames 1b arranged at intervals in the longitudinal direction and longitudinal angle steel 1a respectively arranged at four corner positions of the square frames 1b, the longitudinal angle steel 1a connects the square frames 1b into a whole in the longitudinal direction to form the main frame of the standard bracket joint 1, and in order to further improve the structural stability of the main frame, a diagonal brace 1c is welded between the adjacent square frames 1b for reinforcement. Wherein, the vertical angle steel 1a adopts the angle steel with the specification of 80x80x8 mm.
As shown in fig. 1-4, an angle steel connector 2 and a steel plate connector 3 are arranged at the seam position between the adjacent bracket standard nodes 1 to fix the adjacent bracket standard nodes 1 together. Wherein:
the angle steel connecting pieces 2 are arranged in four groups and are respectively arranged at four corner positions of the seam, each group of angle steel connecting pieces 2 consists of angle steel 2a and a plurality of bolts 2b, the angle steel 2a is arranged along the longitudinal angle steel 1a of the bracket standard knot 1 in an attaching mode and is arranged on two sides of the seam in a bridging mode, and the angle steel 2a is fixed on the longitudinal angle steel 1a through the bolts 2 b; the angle steel 2a is angle steel with the specification of 63x63x6 mm.
The steel plate connecting pieces 3 are arranged in four groups in number and are arranged at the positions of the seams on the four side wall surfaces respectively, specifically, each group of steel plate connecting pieces 3 is a steel plate 3a which is arranged along the seams in a fitting mode and is welded and fixed, and therefore the adjacent bracket standard knots 1 are connected into a whole.
As shown in fig. 5, a cable groove 4 is formed in the upper surface of the bracket standard knot 1, a plurality of cables are arranged in the cable groove 4, and in order to laterally limit the cable groove 4 and prevent the cable groove from falling, a plurality of limiting reinforcing steel bars 5 are arranged on two sides of the upper surface of the bracket standard knot 1 at intervals along the longitudinal direction.
