Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] On the basis of ensuring the strength of the cladding plate, the hot-rolled channel steel for the pipe trench cover not only has the effects of anti-slip, sound insulation and shock load relief, but also the outer stripes can ensure the timely drainage of rainwater flowing through its surface during the rainy season, thus effectively ensuring safety of the vehicle on which it operates.

[0031] refer to figure 1 The hot-rolled channel steel for the trench cover includes a hot-rolled channel steel body for the trench cover, 4 concave stripes on the outer side of the web, and 5 concave stripes on the outer side of the flange. The hot-rolled channel steel body for the trench cover has a web 1 1. The first wing plate 2 and the seco...

Abstract

The invention discloses a rolling device of hot-rolled steel channel for a pipe ditch cover plate and a production method. The steel channel comprises a web plate, a first wing plate and a second wing plate, wherein the web plate is rectangular, and two ends of the web plate are respectively connected with the first wing plate and the second wing plate. The rolling device comprises a rolling device body for rolling a hot-rolled steel channel body for the pipe ditch cover plate and a finishing mill for rolling web plate outer side stripes and flange outer side stripes on the hot-rolled steel channel body for the pipe ditch cover plate. The finishing mill is provided with an upper horizontal roller and a lower horizontal roller, and the central axis of the upper horizontal roller and the central axis of the lower horizontal roller are mutually parallel. The finishing mill is provided with a left vertical roller and a right vertical roller, and the central axis of the left vertical roller and the central axis of the right vertical roller are mutually parallel. By the adoption of the technical scheme, the production period of a streel structure production enterprise is shortened, the manufacturing cost of the enterprise is saved, and the stability and rigidity of the hot-rolled steel channel for the pipe ditch cover plate are improved.

Description

technical field [0001] The invention relates to the field related to materials for pipe trench cover plates used in construction, in particular to channel steel for pipe trench cover plates, rolling equipment and rolling methods for channel steel for pipe trench cover plates. Background technique [0002] During the construction of facilities such as subways, trestles, three-dimensional parking garages, steep slope lanes, and housing passages, as well as during the construction of facilities such as road repairs, construction of access roads in disaster areas, and construction of temporary platforms, the use of cladding panels can effectively reduce construction time and improve work efficiency. With the continuous development of the domestic steel structure field, the original cladding panels made of concrete and steel bars began to be gradually replaced by steel cladding panels. The cladding panels made of conventional hot-rolled H-shaped steel or cold-formed steel, when u...
