[0002] In bridge construction, piers and tie beams play a crucial role. A pier is a columnar structure perpendicular to the ground, typically used to carry loads transferred from the upper portion of the bridge. A tie beam is a horizontal beam that connects the piers and enhances the overall stability of the structure. Therefore, the quality of the concrete pouring at the connection between the pier and tie beam is crucial, impacting the stability, safety, and durability of the bridge.

[0003] Patent publication number CN219793651U discloses a simplified pile-column tie beam formwork, comprising a tie beam formwork body, a fastening assembly, and a reinforcement assembly. The tie beam formwork body is used to determine the position and size of concrete components. The fastening assemblies are spaced apart and mounted on the exterior of the tie beam formwork body, equidistantly arranged from bottom to top along the exterior of the tie beam formwork body. Multiple sets of reinforcement assemblies are spaced apart and mounted on either side of the tie beam formwork body. The reinforcement assemblies and fastening assemblies are bolted together. This patent significantly reduces formwork costs, avoids hoisting steps, and reduces construction accidents caused by hoisting. However, this patent also has the following shortcomings: Currently, during tie beam casting, due to the coexistence of the pier column reinforcement cage and tie beam reinforcement at the connection point between the tie beam end and the pier column, the reinforcement density is high, making it difficult for coarse aggregate to flow into the pier column. This can easily result in a thicker concrete slurry inside the reinforcement cage, affecting the quality of the pier column. Furthermore, the use of concrete pump trucks is costly.

[0004] In view of this, how to change the current situation of thick concrete slurry at the end of the tie beam and poor pouring quality has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0022] Reference Figure 1-4 The present invention provides a tool for pouring concrete into the formwork at the end of a tie beam, comprising a conical bucket 1, a tie rope 2, and a flow channel 3. The conical bucket 1 is an inverted conical ring. The bottom radius of the conical bucket 1 should be slightly larger than the radius of the steel cage 11, so that the conical bucket 1 can be conveniently placed around the steel cage 11 during use and the concrete can flow into the pier column formwork during pouring, avoiding concrete waste. The top radius of the conical bucket 1 is larger than the radius of the steel cage 11, and the top radius of the conical bucket 1 should be selected as large as possible based on the construction site conditions. Selecting a larger radius not only enhances the ability of the conical bucket 1 to guide concrete, but also makes it easier for the concrete to change its flow direction and flow into the steel cage 11.

[0023] Multiple connecting ears 4 are fixedly connected to the top surface of the conical bucket 1 by welding. The multiple connecting ears 4 are distributed at intervals in a circle. The multiple connecting ears 4 are provided with multiple tie ropes 2 in one-to-one correspondence. The connecting ears 4 are provided with through holes 5. The through holes 5 are connected to one end of the tie rope 2, which makes the operation more convenient. The other end of the tie rope 2 is used to connect to the steel cage 11 above the conical bucket 1. The conical bucket 1 is hoisted in the pouring position by cooperating with the multiple tie ropes 2.

[0024] The conical bucket 1 includes multiple conical bucket units 6, and the two ends of the conical bucket units 6 are respectively connected with extension plates 7. The multiple conical bucket units 6 are spliced into a circular array to form the conical bucket 1. The extension plates 7 of adjacent conical bucket units 6 are abutted, and the adjacent extension plates 7 are fixedly connected by multiple fasteners 12.

[0025] The material of the conical bucket body 6 can be selected from aluminum alloy. The aluminum alloy plate is easy to process and light in weight, easy to assemble and transport, and can meet construction needs. The thickness of the conical bucket body 6 is relatively thin, and multiple stiffening plates 8 can be fixedly connected to the outer wall of the conical bucket body 6. The multiple stiffening plates 8 are arranged at intervals to enhance the bearing capacity of the conical bucket body 6 and extend its service life.

[0026] A chute 3 is located above the conical hopper 1. This chute 3 has a U-shaped cross-section and is tilted to enhance concrete flow. Connecting plates 9 are fixedly attached to either side of the lower surface of the chute 3. These plates are provided with strip grooves 10, which are fixedly connected to a support frame 13 via multiple bolts. When the bolts are loose, the chute 3 can be moved along the axis of the strip grooves, adjusting the lower end of the chute 3 to be above the conical hopper 1. This ensures that concrete can be directed into the conical hopper 1 during pouring. Once the position is adjusted appropriately, the bolts are tightened one by one.

[0027] The chute 3 is detachably connected to a support frame 13, which is located on the peripheral side of the steel cage 11. The chute 3 is tilted on the support frame 13. The support frame 13 is used to provide support for the chute 3 to ensure that the chute 3 is stably injected into the conical bucket 1. The support frame 13 is detachably connected to the chute 3.

[0028] The support frame 13 includes four columns distributed in a rectangular shape and the columns are located at the four corners of the rectangle. Cross bars are set between the columns to enhance the stability of the frame. The height of the column on the side away from the conical bucket 1 is greater than the height of the column on the other side to facilitate the tilting setting of the chute. Connecting blocks are set at the top of the two columns, and bolts pass through the connecting blocks and are connected to the strip groove 10 in a lockable manner.

[0029] The inner side walls of the joints of adjacent extension plates 7 are bonded with adhesive tape (not shown in the figure) to improve the sealing of the side walls of the conical bucket 1, prevent cement slurry from flowing out of the joints, and improve construction quality.

[0030] The working principle of the present invention is as follows: a plurality of conical bucket units 6 are assembled into a conical bucket 1, which is sleeved around the steel cage 11, and the conical bucket 1 and the steel cage 11 are firmly connected with a tie rope 2. Concrete is poured into the conical bucket 1 through the flow channel 3. The conical bucket 1 changes the flow direction of the concrete and forces the concrete to flow into the steel cage 11 through the gaps between the steel cages 11, thereby increasing the concrete aggregate in the steel cage 11 and reducing the slurry thickness in the steel cage 11 at the end of the tie beam.

[0031] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0032] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
