Embodiment 1

[0061] Such as Figure 1a , Figure 1b As shown, in this embodiment, the channel profile steel-11 is a rectangular channel profile steel composed of the channel leg 11b, the channel waist 11a, and the leg end hook 11c. The inner surface of the leg end hook 11c is a plane, and an edge A plurality of teeth 11d are longitudinally arranged in the channel section steel-11; the anchor rod-12 is a cylindrical anchor rod, and the non-connecting end of the anchor rod-12 is provided with a boss 12a, and the connecting end of the anchor rod 12 passes through the inner boss 12c and the outer convex The platform 12b is connected to the groove waist 11a; the connecting end of the anchor rod 12 passes through the groove waist 11a and then extends into the channel section steel 11, and there is no gap connection between the two: specifically include the following steps:

[0062] 1) Cut the channel section steel-11 to length according to the length of the drawing, and then place it on the feed...

Embodiment 2

[0067] Such as Figure 2a , Figure 2b As shown, in the present embodiment, channel profile steel 2 21 is a V-shaped channel profile steel composed of channel leg 21b, channel waist 21a, and leg end hook 21c, and the inner surface of leg end hook 21c is inclined inwardly and upwardly Slope, on which a plurality of teeth 21d are arranged longitudinally along the channel section steel 21; the anchor rod 22 is a cylindrical anchor rod, and the non-connecting end is provided with a boss 22a, and the connecting end is not provided with a boss; the end surface of the connecting end and the groove The outer surfaces of the groove waists 21a of the profiled steel 21 are firmly connected together by means of metallurgical fusion and seam welding.

[0068] The specific manufacturing process is as follows:

[0069] 1) Place the channel section steel 21 on the workbench after cutting to length according to the length of the drawing;

[0070] 2) draw a line on the outer surface of the g...

Embodiment 3

[0075] Such as Figure 3a , Figure 3b As shown, in this embodiment, the channel section steel 3 31 is a rectangular channel section steel composed of the channel leg 31b, the channel waist 31a, and the leg end hook 31c; the inner surface of the leg end hook 31c is an inclined surface inclined inwardly and upwardly The anchor rod three 32 is an I-shaped steel anchor rod; the connecting end surface of the anchor rod three 32 and the outer surface of the groove waist 31a of the channel section steel three 31 are fixedly connected together by metallurgical fusion.

[0076] The specific manufacturing process is as follows:

[0077] 1) Cut the channel section steel 331 to length according to the length of the drawing and place it on the workbench;

[0078] 2) draw a line on the outer surface of the groove waist 31a, and locate the fixed position of the anchor rod three 32;

[0079] 3) Place the anchor rod three 32 at a fixed position, and make the connecting end surface of the a...

Abstract

The invention relates to an embedded channel with anchor rods and channel profile steel in gapless connection and a manufacturing method. The embedded channel comprises the channel profile steel and a plurality of anchor rods fixedly connected with the channel profile steel, and the connecting ends of the anchor rods make contact with the outer surface of the groove waist of the channel profile steel or penetrate through the groove waist to stretch into the channel profile steel; and gaps do not exist on all contact surfaces between the anchor rods and the channel profile steel in a metallurgical fusion mode or a metallurgical fusion and metallurgical filling mode. According to the embedded channel and the manufacturing method, the problems that an embedded channel is corroded, the strength is reduced, and the fatigue life is shortened due to the fact that gaps exist in the joints between anchor rods and channel profile steel are solved, the service life of the embedded channel is effectively prolonged, and potential safety hazards in the using process of the embedded channel are eliminated.

Description

technical field [0001] The invention relates to the technical field of pre-buried channels, in particular to a pre-buried channel in which an anchor rod and a channel profile steel are connected without gaps and a manufacturing method thereof. Background technique [0002] Pre-buried channels are widely used in subway tunnels, high-speed rail tunnels, cable trenches, underground pipe galleries, glass curtain walls, mechanical equipment and other fields; It consists of two anchor rods, and the conventional connection method is riveting or seam welding. The cross-section of the channel steel is in the shape of a channel, which is composed of a channel leg, a channel waist and an inwardly bent hook at the end of the channel leg; the anchor rod usually includes a cylindrical anchor rod or an I-shaped anchor rod. [0003] When the channel profile steel and the anchor rod are connected by riveting, the anchor hole needs to be punched out on the channel profile steel channel waist...
