DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0027] The preferred embodiment of the groove type embedded part for high-speed railway bridge pier provided by the utility model is as follows: Figures 1 to 5 As shown: a channel type embedded part for high-speed railway piers, including a channel steel 1, a tightening component 2 is arranged on one side inside the channel steel 1, an anchor cylinder 4 is fixedly connected with equal intervals on the other side of the channel steel 1, and an adjustment component 5 is arranged on one side of the anchor cylinder 4.

[0028] The clamping assembly 2 includes a fixing groove 204, which is evenly spaced on the inner wall of the channel steel 1. The inner wall of the fixing groove 204 is fixedly connected with a fixing spring 203. One end of the fixing spring 203 is fixedly connected with a sliding block 207 extending to the outside of the fixing groove 204. One end of the sliding block 207 is fixedly connected with a clamping plate 201. After the T-shaped bolt is inserted into the channel steel 1, the elastic force of the fixing spring 203 can be used to make the clamping plate 201 move to fit closely to one side of the T-shaped bolt, and make the other end of the T-shaped bolt move to fit tightly to the inner wall of the channel steel 1. Then, the sliding clamping plate 201 can be used to compensate for the distance between one side of the clamping plate 201 and the inner wall of the channel steel 1, so that the T-shaped bolt has no space to move forward and backward inside the channel steel 1, thereby improving the applicability of the channel steel 1.

[0029] In this embodiment, anti-skid grooves 202 are evenly spaced on one side of the clamping plate 201, and the anti-skid grooves 202 are inclined at an angle of twenty degrees to the vertical direction. The inclined anti-skid grooves 202 can increase the friction between one side of the clamping plate 201 and one side of the T-bolt.

[0030] In this embodiment, a limiting groove 205 is provided on the inner wall of the fixed groove 204, and both ends of one side of the sliding block 207 are fixedly connected with limiting blocks 206 that slide in cooperation with the inside of the limiting groove 205. By sliding the limiting block 206 in the limiting groove 205, the sliding block 207 drives the locking plate 201 to slide more smoothly.

[0031] In the present embodiment, the inner wall of the channel steel 1 away from the fixed groove 204 is provided with anti-skid grooves 6 at equal intervals, and one side of the inner wall of the channel steel 1 is sloped. The inner wall of the channel steel 1 is sloped, and the anti-skid grooves 6 are provided on the sloped inner wall, which can increase the friction force between the end of the T-shaped bolt away from the clamping plate 201 and the inner wall of the channel steel 1, thereby improving the firmness and stability of the T-shaped bolt and the internal engagement installation of the channel steel 1.

[0032] Example 2

[0033] On the basis of Example 1, a preferred embodiment of the groove-type embedded parts for high-speed railway bridge piers provided by the utility model is as follows: Figures 1 to 5 As shown: the adjustment component 5 includes an adjustment groove 503, the adjustment groove 503 is opened on one side of the anchor barrel 4, a reserved groove 504 is opened on one side of the top of the anchor barrel 4, the inner wall of the reserved groove 504 is movably connected with a fastening bolt 506 extending to the inside of the adjustment groove 503, the inside of the adjustment groove 503 is movably connected with an anchor bar 502 extending to the outside of the anchor barrel 4, one side of the anchor bar 502 is fixedly connected with an embedded plate 501, and the top of the anchor bar 502 is evenly spaced with bolt holes 505, by pulling the embedded plate 501 to drive the anchor bar 502 to slide to a suitable position, and then the fastening bolt 506 and the thread inside the bolt hole 505 cooperate to achieve limited fixation of the anchor bar 502 after sliding, thereby changing the overall length of the anchor bar 502 and the anchor barrel 4, and improving the firmness and stability of the installation between the channel steel 1 and the high-speed railway pier.

[0034] In this embodiment, a sliding structure is formed between the anchor bar 502 and the inside of the adjustment groove 503. The cross-sectional shape of the anchor bar 502 and the adjustment groove 503 is a cross. The sliding of the cross-shaped anchor bar 502 and the inside of the adjustment groove 503 makes the sliding adjustment of the anchor bar 502 smoother.

[0035] In this embodiment, a threaded fitting structure is formed between the fastening bolt 506 and the inside of the bolt hole 505. A regular hexagonal groove is provided at the top of the fastening bolt 506. The threaded fitting between the fastening bolt 506 and the inside of the bolt hole 505 is used to achieve limited fixation of the anchor bar 502 after sliding.

[0036] In addition, a reinforcement block 3 is fixedly connected at an equal angle to one side of the surface of the anchor tube 4. One side of the reinforcement block 3 and one side of the channel steel 1 are welded into an integrated structure. The reinforcement block 3 welded at an equal angle is used to improve the structural strength of the connection between the channel steel 1 and the anchor tube 4.

[0037] The working principle and use process of the utility model are as follows: first, when the high-speed railway bridge pier is large or the bearing capacity of the installation object is large, the fastening bolt 506 can be rotated by a tool such as an inner hexagonal wrench until it is completely disengaged from the inside of the bolt hole 505, and then the embedded plate 501 is pulled to drive the anchor bar 502 to slide to a suitable position, and then the fastening bolt 506 is rotated in the opposite direction to the inside of the suitable bolt hole 505 to achieve the limited fixation of the anchor bar 502 after sliding, and then the overall length of the anchor bar 502 and the anchor tube 4 can be changed, thereby improving the firmness and stability of the installation between the channel steel 1 and the high-speed railway bridge pier;

[0038] Then, the channel steel 1 is installed with the template, and the anchor cylinder 4, the embedded plate 501 and the anchor bar 502 are placed in the steel cage of the high-speed railway pier. After the concrete is poured and formed, the template is removed to realize the installation and fixation between the T-shaped bolt and the inside of the channel steel 1;

[0039] When the T-bolt is inserted into the channel steel 1, the clamping plate 201 is pushed forcefully so that the sliding block 207 slides inside the fixing groove 204 and compresses the fixing spring 203 to a suitable position. Then, the T-bolt is rotated and the force pushing the T-bolt is reduced. At this time, the elastic force of the fixing spring 203 is utilized to make the sliding block 207 slide and drive the clamping plate 201 to move, so that the T-bolt can move and tightly clamp against the inner wall of the channel steel 1, thereby achieving a preliminary clamping installation between the T-bolt and the inside of the channel steel 1, and then the sliding clamping plate 201 can be utilized to compensate for the distance between one side of the clamping plate 201 and the inner wall of the channel steel 1, and the anti-slip tooth groove 6 can be utilized to further increase the friction between the other end of the T-bolt and the inner wall of the channel steel 1, thereby improving the stability of the clamping installation between T-bolts of different sizes and the channel steel 1, and improving the applicability of the channel steel 1.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
