Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a No. 0 block bracket structure. Background Art

[0002] The bracket is a critical load-bearing structure fixed to the top of the pier column, supporting the loads of the 0# bracket, formwork, concrete, and construction. Its design loads take into account the weight of the concrete, the weight of the formwork, the weight of people and equipment, wind loads, and impact loads. Most existing brackets require multiple large steel plates to be embedded in the pier column surface, which significantly damages the pier cross-section. Furthermore, the installation process involves extensive welding, making assembly and disassembly inconvenient and welding at height dangerous. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a No. 0 block bracket structure.

[0004] The purpose of the utility model is achieved through the following technical solutions: a No. 0 block bracket structure, comprising an embedded component, a horizontal support component and a diagonal support component; two embedded components are embedded in the side of the pier body, one above and one below, and mesh sheets are provided at the bottom of the two embedded components in the pier body; one end of the horizontal support component is connected to the embedded component above; the bottom end of the diagonal support component is connected to the embedded component below, and the top end of the diagonal support component is connected to the end of the horizontal support component away from the pier body;

[0005] An anchor is also pre-embedded on the pier body, and one end of the horizontal support assembly close to the pier body is connected to the anchor.

The connecting structure facilitates connecting the diagonal braces to the horizontal support assembly.

[0012] In some embodiments, the embedded assembly includes an upper connecting plate, a lower connecting plate, and a riser;

[0013] The top and bottom of the vertical plate are connected to the upper and lower connecting plates, respectively. One end of each of the upper and lower connecting plates, as well as the vertical plate, is embedded within the pier. The end of the upper connecting plate, located outside the pier, serves as a load-bearing portion. A diagonal brace is provided between the bottom of the load-bearing portion and the vertical plate. This pre-embedded assembly minimizes damage to the pier's cross-section and can be removed later, minimizing the impact on the pier's structural strength.

[0014] In some embodiments, the horizontal support assembly further includes an auxiliary anchoring structure comprising vertical ribs and transverse ribs. The vertical ribs are disposed on the I-beam at one end near the pier shaft and perpendicular to the web and flange of the I-beam. The transverse ribs are disposed horizontally and connected to the vertical ribs and the web of the I-beam. The anchors are connected to the vertical ribs. The auxiliary anchoring structure provides a stable connection between the anchors and the horizontal support assembly.

[0015] In some embodiments, the anchor comprises a precision-rolled threaded steel bar and a precision-rolled nut. One end of the precision-rolled threaded steel bar is embedded in the pier shaft, while the other end passes through the vertical ribs and is threadedly connected to the precision-rolled nut. A pad is provided at one end of the precision-rolled nut, and the precision-rolled nut abuts against the vertical ribs via the pad. The precision-rolled threaded steel bar stabilizes the horizontal support assembly on the pier shaft.
