Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] refer to Figures 1 to 4 ,like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a steel casing for a building construction pier, which mainly consists of several steel casing bodies 1, stairs 3, several guide members 4, and a pier pier 5. The several steel casing bodies 1 together form a ring structure with a shape similar to a rectangle. The pier pier 5 is located inside this ring structure. The steel casing body 1 is mainly composed of a relatively outer cofferdam 11 and a relatively inner inner wall 12, and the cofferdam 11 and the inner wall 12 are parallel to each other. In order to enhance the connection reliability of the steel casing body 1, several parallel reinforcing ribs 13 are provided between the cofferdam 11 and the inner wall 12. In addition, the cofferdam 11 and the inner wall 12 are connected by several connectors 2 to further improve the reliability of the connection between the cofferdam 11 and the inner wall 12. The staircase 3 is located on the inner side of the inner wall 12 of one of the steel casing bodies 1. Several guide components 4 are spaced apart and welded to the inner wall 12. The guide components 4 slide with the pier foundation 5, so that the guide components 4 can drive the steel casing body 1 to move upward more smoothly during the pouring.

[0033] like Figure 3As shown, several first supports 31 are connected to the staircase 3, and second supports 32 are connected to the first supports 31. The first supports 31 are horizontally positioned and extend inward along the staircase 3. One end of the second support 32 is connected to the inner end of the first support 31, and the other end is connected to a limiting frame 33. The limiting frame 33 serves to connect multiple second supports 32. A hanging lug 34 is connected to the inner side of the limiting frame 33. When hoisting is required, the hook can be connected to the hanging lug 34 for hoisting operation.

[0034] like Figure 4 As shown, the guide component 4 mainly consists of an adjustment assembly and a pressing assembly. The adjustment assembly mainly consists of a fixed channel steel 41, a movable channel steel 42, and a bolt pair 43. The pressing assembly mainly consists of a wheel frame 46 and a guide wheel 47 mounted on the wheel frame 46. The outer end of the fixed channel steel 41 is welded to the inner wall 12. Both the fixed channel steel 41 and the movable channel steel 42 are C-shaped channel steels. The movable channel steel 42 is accommodated within the fixed channel steel 41 and slides in cooperation with it. The fixed channel steel 41 has several parallel first connecting grooves 411, and the movable channel steel 42 has several parallel second connecting grooves 421. The first connecting grooves 411 are located below the second connecting grooves 421. When the second connecting grooves 421 and the first connecting grooves 411 are vertically aligned, the bolt is passed downward through the second connecting grooves 421 and the first connecting grooves 411 in sequence, and then the nut is tightened at the lower end of the bolt to achieve relative fixation between the fixed channel steel 41 and the movable channel steel 42. A first connecting plate 44 is welded to the inner end of the movable channel steel 42, and a second connecting plate 45 is welded to the wheel frame 46. The first connecting plate 44 and the second connecting plate 45 are locked together by another bolt pair 43. By setting the bolt pair 43 between the first connecting plate 44 and the second connecting plate 45, the loading and unloading of the movable channel steel 42 and the wheel frame 46 can be made more convenient. The guide wheel 47 abuts against the side of the pier abutment 5. When the steel caisson body 1 rises as a whole, the guide wheel 47 rolls along the pier abutment 5, which can make the rise of the steel caisson body 1 more stable.

[0035] The bolt pair 43, consisting of a bolt and a nut, serves to connect and lock the fixed channel steel 41 and the movable channel steel 42. The structure of the bolt pair 43 makes position adjustment and locking between the fixed channel steel 41 and the movable channel steel 42 more convenient and reliable. Furthermore, by adjusting the position of the movable channel steel 42 on the fixed channel steel 41, the gap between the guide wheel 47 and the pier cap 5 can be adjusted. Therefore, adjusting the position of the guide wheel can adapt to different working conditions or compensate for installation errors.

[0036] In summary, this utility model improves the overall connection reliability of the steel casing body 1 by setting reinforcing ribs 13 and connectors 2 between the cofferdam 11 and the inner wall 12; it makes construction more convenient for workers by setting up stairs 3; it makes stairs 3 more robust and improves safety by setting up first support 31 and second support 32; and it makes the steel casing body 1 rise more smoothly by setting up guides 4, which increases construction safety and improves the accuracy of construction dimensions.
