Embodiment Construction
[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be more clearly defined.
[0021] see figure 1 and figure 2 , an expandable hot-rolled angle steel, comprising a hot-rolled steel body. The steel plates 1 are perpendicular to each other, and the two steel plates 1 connected to the two ends of the same steel plate 1 are parallel to each other. The combined structure makes the hot-rolled angle steel body have better expandability and can be freely expanded according to site conditions.
[0022] The right side of the steel plate 1 is provided with a connecting groove 2 near the edge, and the positions of the connecting grooves 2 on two adjacent steel plates 1 are arranged at intervals in the form of one above the other. T...

The invention discloses expandable hot-rolled angle steel. The expandable hot-rolled angle steel comprises a hot-rolled angle steel body. The hot-rolled angle steel body is formed by connecting a plurality of steel plates, and every two adjacent steel plates are connected in a tail-to-end manner. A connecting groove is formed in the position, close to the edge, of the right side of each steel plate. A plurality of first threaded holes are formed between the connecting grooves and the right side walls of the steel plates. Chamfers are arranged at the opening positions, located at the right sidewalls of the steel plates, of the first threaded holes. A plurality of second threaded holes are formed in the groove inner walls, opposite to the first threaded holes, in the connecting grooves. Connecting strips are mounted on the left side walls of the steel plates. A plurality of third threaded holes are formed in the connecting strips. The first threaded holes, the second threaded holes andthe third threaded holes are connected through screws. By means of the manner, the expandable hot-rolled angle steel adopts the screw connection mode for expanding of the hot-rolled angle steel instead of the welding mode, so that the expanding speed is increased.
Description
technical field [0001] The invention relates to the field of metallurgy, in particular to an expandable hot-rolled angle steel. Background technique [0002] Angle steel, commonly known as angle iron, is a long strip of steel whose two sides are perpendicular to each other. Angle steel can be used to form various stress-bearing components according to the different needs of the structure, and can also be used as connecting parts between components. It is widely used in various building structures. and engineering structures, such as beams, bridges, transmission towers, lifting and transport machinery, ships, industrial furnaces, reaction towers, container racks and warehouses. [0003] The traditional angle steel is connected by welding, and the size of the angle steel is determined at the factory. When the size is not in compliance, it needs to be remade, and the size cannot be adjusted in time. SUMMARY OF THE INVENTION [0004] The main technical problem solved by the p...
