[0034] In order to make the personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor are within the scope of protection of the present application.

[0035] The anchor system provided by the embodiments of the present application can solve the technical problem that when the web piece moves out of the projection range of the cross beam along the support beam, it is usually located at the cantilever end of the support beam, at this time, the stress on both sides of the support beam bracket may be uneven, which can easily cause the support beam on the side opposite to the sliding direction of the web piece to be out of engagement with the bracket, and even accidents such as overturning of the support beam and falling of the web piece, which has a great safety risk.

[0036] Referring to Figure 1 and Figure 2 , it is an anchor system provided by the embodiments of the present application, which can include: a plurality of brackets 1, each of which is used for fixing to a pier column 2 of a bridge; a support beam 3 supported on the bracket 1 by a height-adjustable support device, and the bracket 1 and the support beam 3 are connected by a movable fixing assembly 4, and the distance between the support beam 3 and the bracket 1 can be adjusted by the height-adjustable support device; the movable fixing assembly includes a movable end plate 41 fixed to the support beam 3, and a fixed end plate 42 fixed to the bracket 1, the fixed end plate 42 is connected to the movable end plate 41, it should be understood that the movable end plate 41 will also move relative to the fixed end plate 42 as the height of the support beam 3 changes, but even if the relative movement occurs, the movable end plate 41 can still be connected to the movable end plate 41.

[0037] The embodiment of the application is supported by the height-adjustable support device on the corbel 1, so that when the truss piece 6 needs to be removed after the horizontal beam 7 is poured, the height of the height-adjustable support device can be adjusted to reduce the height of the support beam 3 to complete the disassembly. When the truss piece 6 supports the pouring of the horizontal beam 7, the top surface of the truss piece 6 will be in close contact with the bottom surface of the horizontal beam 7. After the construction of the horizontal beam 7 is completed, the truss piece 6 is inconvenient to remove even if it needs to be removed. At this time, the height of the support beam 3 can be reduced by adjusting the height-adjustable support device, so that the height of the support beam 3 in the vertical direction is reduced, so that the truss piece 6 supported on the top surface of the support beam 3 has a certain gap with the horizontal beam 7, and the truss piece 6 is more convenient to move. Further, the movable end plate 41 can move relative to the fixed end plate 42, that is, even if the height of the support beam 3 is reduced, the movable end plate 41 can be connected with the fixed end plate 42 to fix the support beam 3 relative to the corbel 1, limit the vertical relative displacement, solve the technical problem that the truss piece 6 moving along the support beam 3 in the related art may cause uneven stress on both sides of the support beam corbel, easily cause the support beam on the opposite side of the truss piece to be out of engagement with the corbel, and even cause accidents such as overturning of the support beam and falling of the truss piece, which has a great safety risk.

[0038] In some optional embodiments, the surface of the movable end plate 41 is perpendicular to the extension direction of the support beam 3, and the surface of the fixed end plate 42 is also perpendicular to the extension direction of the support beam 3. The movable end plate 41 and the fixed end plate 42 are connected by the height-adjusting assembly. It should be understood that the movable end plate 41 can move relative to the fixed end plate 42 in a direction perpendicular to the extension direction of the support beam 3. At this time, the movable end plate 41 and the fixed end plate 42 are both arranged as plates extending in a direction perpendicular to the extension direction of the support beam 3. The adjustment range between the movable end plate 41 and the fixed end plate 42 can be larger, so that the movable end plate 41 and the fixed end plate 42 can have a wider use scenario.

[0039] Referring to Figure 4As shown, in some alternative embodiments, the height adjustment assembly can include a plurality of first pin shaft holes 411 formed in the movable end plate 41 and a plurality of second pin shaft holes 421 formed in the fixed end plate 42, the plurality of first pin shaft holes 411 are arranged along the extension direction of the movable end plate 41; the height adjustment assembly further includes a fastener 43, the fastener 43 is arranged through the first pin shaft hole 411 and the second pin shaft hole 421 to connect the movable end plate 41 and the fixed end plate 42, in the embodiment of the application, the fastener 43 can be arranged as a connecting bolt, by arranging the connecting bolt through the first pin shaft hole 411 and the second pin shaft hole 421, the movable end plate 41 can be connected with the fixed end plate 42, it can be considered that the movable end plate 41 is fixed relative to the fixed end plate 42 at this time, at this time the support beam 3 can be fixed with the corbel 1 through the movable end plate 41, the truss piece 6 is moved on the support beam 3, the support beam 3 and the corbel are avoided to be out of engagement, and the risk of overturning is reduced.

[0040] Further, a plurality of first pin shaft holes 411 are arranged along the extension direction of the movable end plate 41, by using the first pin shaft hole 411 and the second pin shaft hole 421 with different heights, the position relationship between the movable end plate 41 and the fixed end plate 42 has a larger adjustment range, which can adapt to a larger range of distance changes between the support beam 3 and the corbel 1. Referring to Figure 5 and Figure 6 As shown, preferably, a plurality of rows of first pin shaft holes 411 can be formed in the movable end plate 41, each row of first pin shaft holes 411 includes at least two first pin shaft holes 411 at the same height, and the fixed end plate 42 is formed with two second pin shaft holes 421 at the same height, when the connecting bolt or the pin shaft is used to connect the first pin shaft hole 411 and the second pin shaft hole 421, two connecting bolts or pin shafts are arranged through the two groups of corresponding first pin shaft holes 411 and second pin shaft holes 421, which enhances the connection stability between the fixed end plate 42 and the movable end plate 41. By using the connecting bolt or the pin shaft to connect the movable end plate 41 and the fixed end plate 42, the anchoring of the movable end plate 41 and the fixed end plate 42 can be completed faster before the truss piece 6 is transversely moved and removed, the anchoring of the support beam and the corbel is realized, the operation is simple, the risk of high-altitude operation is reduced, the construction quality and precision are improved, and the construction period is shortened. In some other embodiments, the movable end plate 41 and the fixed end plate 42 can also be anchored by other ways, such as direct welding.

The second scale 422 can have small gaps between the scale lines. The second scale 422 can be used to judge whether the heights of the height-adjustable support devices on the plurality of corbels 1 are adjusted to be substantially consistent, which can increase the consistency of the heights of the height-adjustable support devices, so that the distances between the support beam 3 and the corbels 1 at different positions can be as consistent as possible.
