Description

Technical Field

[0001] The utility model particularly relates to a connection structure of a bottom plate and side plates of a steel casing. Background Art

[0002] In the underwater foundation construction of structures such as bridges, steel casings are often needed as water retaining structures for foundation construction. Steel casings are divided into single-wall steel casings and double-wall steel casings. According to construction needs, the side plates and bottom plates of the steel casings are often welded together. After the underwater foundation construction is completed, the bottom plate of the steel casing is generally not removed, and only the side plates of the steel casing are removed. Since the connection positions of the side plates and the bottom plates of the steel casing are at a certain depth below the water surface and are connected by welding, if only the side plates of the steel casing are removed, underwater cutting is often required, thereby increasing construction safety risks and construction costs. In addition, only the part of the side plates of the steel casing above the water surface is removed, which reduces the recycling rate of the side plates of the steel casing. Utility Model Content

[0033] The working principle of the utility model is:

[0034] As Example 1, in order to better illustrate the design principle of the present application, the design concept of the present application is explained by the installation and removal process of the bottom plate 4 and the side plate 2 of the steel casing:

[0035] Step 1: When assembling and installing the steel casing, first install the bottom plate 4, then install the side plate 2, weld the side plate anti-pull bracket 3 on the side plate 2 of the steel casing, and weld the bottom plate anti-pull bracket 5 on the bottom plate 4 of the steel casing (the bottom plate anti-pull bracket 5 can be set under the load-bearing beam of the bottom plate 4 to facilitate reasonable force);

[0036] Step 2: Install the tie rod 1 between the bottom plate anti-tension bracket 5 and the side plate anti-tension bracket 3 (the tie rod 1 can be made of finely rolled threaded steel bars as needed). An upper lifting ring 6, a first gasket 81, and a first nut 8 are provided at the upper end of the tie rod 1, and a lower lifting ring 7, a second gasket 91, and a second nut 9 are provided at the lower end of the tie rod 1. Figure 1 As shown, the first nut 8 is threadedly locked on the upper end of the pull rod 1, and a first gasket 81 is pressed between the first nut 8 and the side plate anti-tension bracket 3; the second nut 9 is threadedly locked on the lower end of the pull rod 1, and a second gasket 91 is pressed between the second nut 9 and the bottom plate anti-tension bracket 5; thereby, the two ends of the pull rod 1 can be detachably mounted on the side plate anti-tension bracket 3 and the bottom plate anti-tension bracket 5; then a rope body 10 is connected to the upper lifting ring 6, and another rope body 10 is connected to the lower lifting ring 7, and the two rope bodies 10 are respectively connected to the top of the steel casing, and the above-mentioned rope body 10 can be realized by steel wire rope.

[0037] Step 3: lower the steel casing, pour the underwater bottom concrete, and then complete the foundation or foundation construction, and start to remove the steel casing side plate 2;

[0038] Step 4. When disassembling the side panel 2, screw the first nut 8 and the second nut 9 to remove the first nut 8 and the second nut 9 from the pull rod 1, and release the rope 10 on the upper lifting ring 6 from the top of the steel casing. Under the action of weight, the pull rod 1 moves downward to disengage from the side panel reverse pull leg 3 and the bottom panel reverse pull leg 5 and moves to the bottom of the bottom plate 4. Then, pull the rope 10 connected to the lower lifting ring 7 at the top of the steel casing. The rope 10 lifts the pull rod 1 out of the water, completing the removal of the pull rod 1. At this time, the connection between the side panel 2 and the bottom plate 4 is released.
