Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a tool for pouring concrete at the bottom of steel columns. Background Technology

[0002] Currently, in the construction of steel structures, the common practice for pouring concrete into the base of steel columns involves creating a hole on the side, transporting the concrete to the hole using a small container, and then using a shovel-like tool to gradually scoop the concrete into the steel column before vibration compaction. However, this method relies heavily on manual labor to transport the concrete to the hole, resulting in low efficiency and high labor intensity. Furthermore, the concrete is prone to spillage during the shovel-like process, further impacting construction efficiency. Utility Model Content

[0003] This utility model provides a tool for pouring concrete at the bottom of steel columns to solve the technical problems existing in the prior art. It completely solves the problem that the process of pouring concrete at the bottom of steel columns in steel structures requires a lot of manual labor and has low construction efficiency, and it can be recycled.

[0004] This utility model is implemented as follows: A tool for pouring concrete at the bottom of a steel column includes a hopper and a suspension assembly. The hopper consists of a base plate and side plates surrounding the upper three sides of the base plate. An insert plate that can be inserted into the pouring hole of the steel column extends outward from the front end of the base plate without side plates. Through holes are opened at the upper rear ends of the two opposite side plates. The suspension assembly consists of a connecting rod with threads at both ends, a limiting nut, and two barbed suspension rods. The barbed suspension rods have through holes at their tail ends. The two ends of the connecting rod pass through the two through holes of the side plates and the through holes of the barbed suspension rods. The two barbed suspension rods are movably fixed to the outside of the two side plates by the limiting nuts.

[0005] The insert is trapezoidal, with the front end of the insert having a short base.

[0006] The advantages and technical effects of this utility model are as follows: 1. By moving the pouring inlet from the side to the top using a hopper, automated pouring equipment can be used to transport concrete, improving work efficiency.

[0007] 2. The tool of this utility model has a self-suspension system. The barbed self-suspension rod can be connected to the steel column ear plate for secure fixing.

[0008] 3. The tool of this utility model avoids the process of manually shoveling concrete into the steel column through the pouring port during use, thus saving labor.

[0009] 4. The tool of this utility model has a simple installation process and can be reused repeatedly with a high turnover rate. Attached Figure Description

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0012] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0013] Furthermore, the terms “first”, “second”, etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0014] Therefore, features specified with "first," "second," etc., may explicitly or implicitly include one or more of those features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] like Figure 1-3As shown, the tool for pouring concrete at the bottom of a steel column according to this utility model includes a hopper 1 and a suspension assembly 2. The hopper consists of a base plate 1-4 and side plates 1-2 surrounding the upper three sides of the base plate. An insert 1-1 that can be inserted into the pouring hole of the steel column extends outward from the front end of the base plate without side plates. The upper rear ends of the two opposing side plates 1-2 are respectively provided with through holes 1-3. The suspension assembly 2 consists of a connecting rod 2-1 with threads at both ends, a limiting nut 2-2, and two barbed suspension rods 2-3. The tail end of the barbed suspension rod 2-3 is provided with a through hole. The two ends of the connecting rod 2-1 pass through the two through holes 1-3 of the side plates and the through holes on the barbed suspension rods 2-3. The two barbed suspension rods 2-3 are movably fixed to the outside of the two side plates 1-2 by the limiting nut 2-2.

[0017] Preferably, the insert 1-1 is trapezoidal, and the front end of the insert 1-1 is a short base.

[0018] Specifically, the side plates 1-2 of this utility model are distributed in three directions of the base plate 1-1, leaving a front insert 1-1 for easy connection with the steel column casting hole. The through hole 1-3 is located at the tail of the side plates on the left and right sides of the base plate 1-1. The suspension assembly 2 includes a connecting rod 2-1, a limiting nut 2-2, and a hook-type suspension rod 2-3. The connecting rod 2-1 is connected to the hopper 1 through the through hole 1-3 and fixed in position by the limiting nut 2-2. The two hook-type suspension rods 2-3 are connected to both ends of the connecting rod 2-1 to form a whole, and the other side is hooked to the steel column ear plate during operation.

[0019] The construction method of this utility model is as follows: A pouring hole is made on the side above the steel column to be poured. Then, the insert of the bottom plate is inserted into the pouring hole. The hook-type suspension rod is then connected to the ear plate on the upper part of the steel column, thus attaching it to the steel column. The concrete is then transported to the hopper with the insert through the concrete conveying equipment. The concrete then enters the interior of the steel column along the hopper and the pouring hole. After the required pouring height is reached, the concrete pouring is stopped. By rotating the hook-type suspension rod, the self-suspended pouring device of the steel structure is separated from the steel column, and the concrete inside the steel column is vibrated, thus completing the construction.

[0020] This invention connects a connecting rod to a hopper with insert plates and prevents it from falling off using a limiting nut. The end of the bottom plate insert is inserted into a pouring hole on the side of the steel column. Then, two hook-type suspension rods are hooked onto the ear plates on the upper part of the steel column. During pouring, concrete can be directly transported to the hopper using concrete pouring equipment such as a pump truck. The concrete flows into the interior of the steel column, thus completing the concrete pouring.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
