The channel material is mostly ordinary carbon steel, also has some stainless steel material, has multiple specification models. The manufacturing process generally adopts hot rolling and cold roll forming processes. The channel is embedded in the concrete at a required position, the opening of the channel is outward, and the upper surface and the outer surface of the concrete are in the same plane. In order to enhance the bonding strength of the channel in the concrete, a riveted or welded anchor bolt is added at the bottom of the channel to enhance the bonding strength of the whole channel in the concrete. The embedded channel has the remarkable use characteristic that the installation and connection of devices such as a contact net, a pipeline and the like can be flexibly, conveniently and quickly realized in the use range, so that the embedded channel is called as an embedded channel. In addition, the method can also be used in steel structure systems, and the use method is to weld and connect the channels at required positions in the structure.
The antiskid tooth of current anti-skidding channel is located the upper surface of channel inner chamber and bolt laminating mostly, relies on after the bolt-up and realizes anti-skidding function with the mutual interlock of the antiskid tooth of bolt binding face, has had utility model patent's pre-buried connected system of taking tooth's socket shape ' patent number ZL 200820043743.7. However, since the tooth surface is provided with the dovetail hook, the fastening effect is reduced, and since the occlusion surface is positioned in the inner cavity of the channel, the occlusion state cannot be visually checked, and the good occlusion and anti-skidding effect cannot be completely ensured. Particularly, the tooth sockets are easy to accumulate in the hot galvanizing process, the tooth profiles are shallow and even completely filled when concrete slurry permeates into the channels in the pre-buried pouring process, and once the phenomena occur, the tooth profiles can not be repaired almost and finally the anti-skidding teeth are failed.
In addition, the structure that the anti-skid teeth are arranged on the outer surface of the groove channel needs a specially-made gasket to be matched with the structure to realize the anti-skid function. The gasket is troublesome to manufacture, install and use, and certain cost is increased.

Detailed Description
Embodiments of the present invention are further described below with reference to the accompanying drawings.
Example 1: an anti-skid groove type embedded part comprises a channel 1, as shown in figure 3, the channel 1 is a C-shaped channel, the channel 1 is welded on a steel structure in advance or embedded into a concrete pouring surface, one end of the channel 1 is provided with an opening, and the opening and the mounting surface of the channel 1 are outward; the bottom of the channel 1 is provided with riveted or welded anchors 3 (see fig. 4 and 7) to enhance the bond with the concrete. The opening part is provided with the clamp hook 1B inclined to the bottom surface of the channel 1, the fastening effect with the T-shaped bolt 2 is better, and the overall strength and the bearing capacity of the channel 1 are better. The side of the opening of the channel 1 is provided with anti-skidding teeth I1A, the end face shape of the tooth shape of the anti-skidding teeth I1A is triangular or other tooth shapes, wherein the triangular is the optimal scheme, so that the occlusion is firmer. The anti-skidding teeth I1A are arranged on one side or two sides of the side face of the opening of the channel 1, the arrangement on the two sides is the optimal scheme, as shown in figure 5, a T-shaped bolt 2 is arranged in the channel 1, and as shown in figures 6-7, anti-skidding teeth II 2A matched with the anti-skidding teeth I1A are arranged on the bolt head of the T-shaped bolt 2. The bolt head and the opening part are connected and provided with a groove 2B matched with the clamping hook 1B, and the anti-skid tooth II 2A is arranged at the joint of the groove 2B and the anti-skid tooth I1A. The teeth of the anti-skid teeth I1A and the anti-skid teeth II 2A are vertical teeth.
The installation method comprises the following steps: the head of the T-shaped bolt 2 is placed into an inner cavity of the channel 1 and moved to a required position, the T-shaped bolt 2 is rotated by 90 degrees around the axis of the T-shaped bolt 2, as shown in fig. 6 and 7, the T-shaped bolt 2 which is rotated in place is pulled towards the opening direction, a groove 2B in the bolt head is enabled to be attached to the inner surface of a clamping hook 1B of the channel 1, meanwhile, an anti-skid tooth II 2A arranged on the T-shaped bolt 2 is embedded into and meshed with an anti-skid tooth I1A arranged on the side face of the opening of the channel 1, the T-shaped bolt 2 cannot rotate along the axis of the T-shaped bolt after being meshed, cannot move along the channel 1, is fixed firmly, anti-skid positioning can be directly achieved without assistance of a nut and a gasket, and after being meshed, the gasket, a device to be installed. The occlusion of the anti-skidding teeth has no direct relation with the bolt fastening, the size of the fastening force does not influence the occlusion of the anti-skidding teeth, and the anti-skidding effect is better. In addition, the arrangement direction of the channel 1 can be any one of the downward direction, the leftward direction, the rightward direction and the like, so that the occlusion of the anti-skidding teeth is not directly related to the bolt fastening, the occlusion of the anti-skidding teeth is not influenced by the fastening force, and the anti-skidding effect is better.
As shown in figure 8, the occlusion state of the anti-skid teeth is visual, and the T-shaped bolt 2 can not slide even if the nut is not screwed in for fastening after occlusion, thereby being convenient for installation and construction operation.
Example 2: the present embodiment is different from embodiment 1 in that: as shown in fig. 11, a gasket 3 is arranged on the channel 1, the gasket 3 is arranged on the top surface of the channel 1 at the opening end, a boss matched with the opening of the channel 1 is arranged on the gasket 3, the boss is clamped into the opening, and an anti-slip tooth iii matched with the anti-slip tooth i 1A is arranged on the side surface of the boss. Be provided with on gasket 3 with T shape spiral 2 assorted through-holes, gasket 3 passes the double-screw bolt part of T shape bolt 2 through the through-hole, and gasket 3 is connected with channel 1 through the interlock of anti-skidding tooth III and anti-skidding tooth I1A. The gasket 3 can multiply the anti-skid and locking effects of the embedded part.
The installation mode is as follows: after the embedded parts in the embodiment 1 are connected, the gasket 3 penetrates into the stud part of the T-shaped bolt 2 through the through hole, the gasket 3 is moved to the opening of the channel 1, the boss of the gasket 3 extends into the opening, the anti-skid teeth III 5 and the anti-skid teeth I1A are mutually meshed, and the boss part of the gasket 3 is fully extended into the opening by force. If the general gasket shown in fig. 9 is used, although the anti-slip effect can be effectively achieved as shown in fig. 12, the anti-slip and fastening effects are far less effective than those of the gasket of the present invention.
Compared with the prior art shown in the figures 1 and 2, although the position of the anti-skid teeth is changed, the anti-skid and fastening effects are more excellent because the groove channels and the bolts are correspondingly changed and the original dovetail hooks are reserved, and the anti-skid effect can be achieved without any special gasket.
The invention discloses an anti-skid groove type embedded part which is mainly used for mounting and fixing various devices such as contact networks, pipelines and the like on urban rail transit lines such as magnetic levitation, subways and the like, and is also suitable for fastening connection with the same requirements in other fields (such as rail transit vehicles, building pendant mounting and the like).
