Description

Technical Field

[0001] This utility model relates to the field of column casting technology, specifically a high-reinforcement column concrete casting device. Background Technology

[0002] In building structures, columns, as key load-bearing components, are typically reinforced with a large amount of steel to enhance the structure's load-bearing capacity and seismic performance. However, when the reinforcement ratio of a column is high, the gaps between the steel bars become very small, which significantly reduces the fluidity of the concrete. Traditional concrete pouring methods often struggle to ensure that the concrete evenly fills the interior of the column in such cases, leading to defects such as voids and cracks, which severely weaken the structural stability of the column. Utility Model Content

[0003] The purpose of this utility model is to provide a high-reinforcement column concrete pouring device to solve the problem that traditional concrete pouring methods mentioned in the background art often fail to ensure that the concrete is evenly filled inside the column under such circumstances, resulting in defects such as voids and cracks, which seriously weakens the structural stability of the column.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a concrete pouring device for high-reinforcement columns, comprising a pouring funnel, a pouring pipe fixedly connected to the bottom of the pouring funnel, a graded connection structure at the bottom of the pouring pipe, a graded pipe installed at the bottom of the graded connection structure, and a graded connection structure also provided at the bottom of the graded pipe, the graded connection structure comprising a positioning column, the positioning column fixedly connected to the bottom of the pouring pipe, and a positioning column also fixedly connected to the bottom of the graded pipe, the positioning column having an external thread on its surface, a threaded pipe threaded onto the external thread, a limit pipe fixedly connected to the bottom of the threaded pipe, a rotating rod rotatably connected to the surface of the graded pipe, and a limit block fixedly connected to the surface of the rotating rod.

[0005] Preferably, a circular hole is formed on the surface of the positioning column, the casting pipe is fixedly connected to the top of the circular hole of the positioning column, the grading pipe is inserted into the bottom of the circular hole of the positioning column, and the top of the grading pipe is connected to the bottom of the casting pipe through the circular hole of the positioning column.

[0006] Preferably, the threaded tube moves up and down on the positioning post by rotating on the external thread, and the threaded tube drives the limiting tube to move up and down synchronously.

[0007] Preferably, the limiting block rotates on the surface of the grading tube via a rotating rod, and the limiting block is in the shape of a semi-circular ring.

[0008] Preferably, the surface of the positioning post is provided with an annular groove and two sets of rectangular grooves, and the annular groove and the rectangular groove of the positioning post are connected together.

[0009] Preferably, there are two sets of rotating rods and limiting blocks. The rotating rod is engaged in the rectangular groove of the positioning post, and the limiting block is engaged in the annular groove of the positioning post.

[0010] Preferably, the positioning column restricts the position of the grading pipe at the bottom of the casting pipe by means of a rotating rod and a limiting block, and the limiting pipe can be locked onto the outer ring of the two sets of limiting blocks by descending.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This pouring device connects the pouring pipe and the grading pipe through a tiered connection structure. By continuously disassembling the bottom grading pipe and then pouring, the pouring device can perform pouring tasks at different heights of the column.

[0019] Please see Figure 1-5 One embodiment provided by this utility model:

[0020] A concrete pouring device for high-reinforcement columns includes a pouring funnel 1, a pouring pipe 11 fixedly connected to the bottom of the pouring funnel 1, a graded connection structure 2 at the bottom of the pouring pipe 11, a graded pipe 12 installed at the bottom of the graded connection structure 2, and a graded connection structure 2 also at the bottom of the graded pipe 12. The graded connection structure 2 includes a positioning post 21 fixedly connected to the bottom of the pouring pipe 11 and the bottom of the graded pipe 12. An external thread 22 is formed on the surface of the positioning post 21, and a threaded pipe 23 is threadedly connected to the external thread 22. A limit pipe 24 is fixedly connected to the bottom of the threaded pipe 23. A rotating rod 25 is rotatably connected to the surface of the graded pipe 12, and a limit block 26 is fixedly connected to the surface of the rotating rod 25. Figure 2 The grid shape is highly reinforced, and the outer side of the highly reinforced grid is a column. The pouring device is connected to multiple graded pipes 12 at the bottom of the pouring pipe 11 through the graded connection structure 2, so that the pouring funnel 1 can extend into the interior of the column through the pouring pipe 11 and the graded pipes 12 to perform graded pouring, which reduces the generation of voids and cracks, effectively improves the pouring quality of concrete, and ensures the uniformity and reliability of the column structure.

[0021] Furthermore, a circular hole is provided on the surface of the positioning post 21. The casting pipe 11 is fixedly connected to the top of the circular hole of the positioning post 21, and the grading pipe 12 is inserted into the bottom of the circular hole of the positioning post 21. The top of the grading pipe 12 is connected to the bottom of the casting pipe 11 through the circular hole of the positioning post 21. The grading pipe 12 restricts the installation position of the casting pipe 11 through the positioning post 21. The casting pipe 11 can also restrict the installation position of the bottom casting pipe 11 through the positioning post 21 at the bottom of the casting pipe 11.

[0022] Furthermore, the threaded tube 23 rotates on the external thread 22 to move up and down on the positioning post 21. The threaded tube 23 drives the limiting tube 24 to move up and down synchronously. After the rotation is completed, the threaded tube 23 will be restricted to the surface of the positioning post 21 by the external thread 22, thereby achieving automatic locking.

[0023] Furthermore, the limiting block 26 rotates on the surface of the classifier tube 12 via the rotating rod 25. The limiting block 26 is in the shape of a semi-circular ring. The rotating rod 25 and the limiting block 26 are located at the top of the classifier tube 12 and can rotate 180 degrees.

[0024] Furthermore, the surface of the positioning post 21 is provided with an annular groove and two sets of rectangular grooves. The annular groove and the rectangular groove of the positioning post 21 are connected together, so that the rotating rod 25 and the limiting block 26 can be simultaneously engaged in the rectangular groove and the annular groove of the positioning post 21, providing a reserved position for the rotating rod 25 and the limiting block 26.

[0025] Furthermore, there are two sets of rotating rod 25 and limiting block 26. The rotating rod 25 is engaged in the rectangular groove of the positioning post 21, and the limiting block 26 is engaged in the annular groove of the positioning post 21. The two sets of limiting blocks 26 are in contact and connected on the annular groove of the positioning post 21. At this time, the two sets of limiting blocks 26 form a ring and are located directly below the threaded tube 23.

[0026] Furthermore, the positioning post 21 restricts the position of the grading pipe 12 at the bottom of the casting pipe 11 by the rotating rod 25 and the limiting block 26. The limiting pipe 24 can be locked onto the outer ring of the two sets of limiting blocks 26 by descending. The inner ring of the limiting pipe 24 is slightly larger than the outer ring of the two sets of limiting blocks 26, so that the limiting pipe 24 restricts the two sets of limiting blocks 26 to the annular groove of the positioning post 21.

[0027] Working principle: The pouring pipe 11 and the grading pipe 12 are inserted through the high-reinforcement structure into the bottom of the column. Concrete is then poured into the pouring funnel 1. The pouring funnel 1 outputs concrete to the bottom of the column through the pouring pipe 11 and the grading pipe 12. After the concrete at the bottom of the column is poured, the pouring device is removed. The bottom grading pipe 12 is removed through the grading connection structure 2. Simply rotate the threaded pipe 23 on the external thread 22 to disengage the limiting pipe 24 from the surface of the limiting block 26. The limiting block 26 is removed from the annular groove of the positioning column 21 by the rotating rod 25, thereby removing the bottom grading pipe 12. At this time, the overall height of the pouring device is reduced, and the pouring device will pour concrete for the higher part of the column. This process is repeated to pour concrete at different heights of the column, which can make the concrete poured evenly in the column, realize grading pouring, reduce the generation of voids and cracks, effectively improve the quality of concrete pouring, and ensure the uniformity and reliability of the column structure.
