Description

C-shaped beam

Technical Field

The utility model relates to a C type roof beam.

Background

C-beams are widely used in respective metal frame structures, such as frames of cooling towers, as a support for facilitating the installation of other components; the existing C-shaped beam comprises a bottom plate and four side plates vertical to the bottom plate, wherein two side plates positioned in the stress direction are fixedly connected with the bottom plate in a welding way, and the other two side plates are integrally and fixedly connected with the bottom plate; the structure needs welding, so that the structure has the advantages of multiple working procedures, inconvenience in processing, low efficiency, high energy consumption, poor appearance quality, high cost and the like, and working procedures such as electroplating need to be added if corrosion prevention is required.

Disclosure of Invention

The utility model aims at the above-mentioned not enough of prior art, provide a C type roof beam, its manufacturing procedure is few, the preparation is convenient, efficient, the advantage that the energy consumption is low, and appearance quality is good, can reduce the comprehensive cost.

In order to achieve the purpose, the C-shaped beam comprises a bottom plate and four side plates which are connected with the bottom plate and are vertical to the bottom plate; the method is characterized in that: the four side plates are fixedly connected with the bottom plate in a uniform body, wherein two ends of two opposite side plates are fixedly provided with clamping tenons, and two opposite sides of each clamping tenon are provided with more than one sawtooth; the two ends of the two opposite side plates are respectively provided with a clamping groove, the two opposite sides of each clamping groove are respectively provided with more than one zigzag groove corresponding to the saw teeth, and each clamping tenon is positioned in the respective clamping groove;

when in processing, the four side plates and the clamping tenons are formed by bending, so that the processing method has the advantages of less processing procedures, convenience in manufacturing, high efficiency, low energy consumption, no welding seam, good appearance quality and capability of reducing the comprehensive cost; the two side plates with the clamping tenons are positioned in the stress direction, and the clamping tenons are limited and fixed through the sawtooth-shaped grooves, so that enough supporting strength can be provided;

as a further improvement of the utility model, the distance between each tenon and each edge of the corresponding slot is less than 0.15 mm; the smaller distance can not only improve the appearance attractiveness, but also improve the supporting strength;
