Description

Technical Field

[0001] This utility model relates to the field of steel column foundation installation technology, and in particular to an infeeding device for prefabricated steel column foundations. Background Technology

[0002] Steel structure buildings are a widely used type of prefabricated construction. Their components are entirely manufactured in factories, and on-site construction involves only the assembly of these components. The efficiency of on-site assembly determines the overall assembly efficiency of the building. On-site installation of steel columns includes two parts: the connection between columns and the connection between columns and the foundation. For the connection between columns and the foundation, the commonly used on-site construction methods are anchor bolt installation and column base embedding. The former is mostly used in high-rise buildings, while the latter is mostly used in single-story buildings or structures. Regardless of the method used for connecting the columns to the foundation, the anchor bolts or column base embeddings must first be accurately embedded on-site according to the axis position. After the foundation concrete is poured, the steel columns are then hoisted. During hoisting, the position and verticality of the steel columns need to be adjusted so that the column bases fall precisely at the corresponding positions of the anchor bolts or column base embeddings.

[0003] In the prior art, such as CN218437169U, an introductory device for prefabricated steel column foundations is disclosed, which includes a positioning plate installed on the anchor bolts, an introductor arranged on the positioning plate, a steel column foundation component assembled on the introductor, and the steel column foundation component being installed on the positioning plate through the introductor.

[0004] However, in the existing technology, the existing induction device may have poor overall stability due to unreasonable structural design during the process of supporting the steel column foundation and moving and adjusting it. When encountering external interference or uneven ground, it is easy to shake or even overturn, endangering construction safety. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that existing induction devices may have poor overall stability due to unreasonable structural design during the process of supporting steel column foundations and moving and adjusting them, and are prone to shaking or even overturning when encountering external interference or uneven ground, which endangers construction safety. Therefore, a prefabricated steel column foundation induction device is proposed.

[0007] Preferably, the bottom surface of the positioning plate is threaded with a locking bolt.

[0008] Preferably, a limiting hole is formed through the top surface of the fixing frame, and the inner wall of the limiting hole is movably connected to the outer wall of the guide rod.

[0009] Preferably, an adjusting bolt is threaded through the center of the top surface of the fixing frame, and the top end of the connecting plate is engaged with the outer wall of the adjusting bolt.

[0010] Preferably, the outer wall of the fixing frame is provided with a connecting groove, and the connecting plate is movably connected to the inner wall of the connecting groove.

[0011] Preferably, a limiting groove is formed through the upper outer wall of the connecting plate, and a locking bolt is movably connected to the inner wall of the limiting groove.

[0012] Preferably, one end of the second locking bolt is threaded to the inner wall of the connecting groove.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the steel column foundation base is positioned by using four sets of positioning plates and anchor bolts for clamping. Then, a crane is used to place the steel column foundation base into the connecting plate and guide it with guide wheels. Two sets of electric cylinders are activated to push the clamping plates to clamp and fix the steel column foundation to the connecting plate, thus firmly fixing the steel column foundation to the connecting plate and preventing shaking or displacement during the introduction process. Then, the crane is used to lower the steel column foundation, and the connection between the guide rod and the fixing frame guides the downward movement, thereby enabling the holes of the steel column foundation to be accurately introduced and connected with the anchor bolts, improving the stability of the introduction process.

[0015] 2. In this utility model, the setting of the first locking bolt makes it easy for the user to adjust the length of the positioning plate to adapt to steel column foundations of different specifications. By rotating the adjusting bolt and the second locking bolt, the bearing height of the connecting plate can be adjusted, making it easier for the steel column foundation to be lowered onto the connecting plate.

The clamping mechanism 5 includes an electric cylinder 51, a mounting frame 52, a clamping plate 53, an anti-slip pad 54, and a guide wheel 55. The electric cylinder 51 is fixedly connected to the inner wall of the mounting frame 52. One end of the telescopic rod of the electric cylinder 51 is fixedly connected to the clamping plate 53. The anti-slip pad 54 is fixedly connected to the outer wall of the clamping plate 53. The guide wheel 55 is rotatably connected to the top outer wall of the clamping plate 53.

[0024] The specific setup and function of this embodiment are described below. The present invention is positioned by using four sets of positioning plates 11 to engage with the anchor bolts. Then, the steel column foundation base is placed into the connecting plate 4 by a crane and guided by the guide wheel 55. The steel column foundation is clamped and fixed by activating two sets of electric cylinders 51 and pushing the clamping plate 53. The steel column foundation is firmly fixed on the connecting plate 4 to prevent shaking or displacement during the introduction process. Then, the steel column foundation is lowered by the crane. The lowering is guided by the connection between the guide rod 2 and the fixing frame 3, so that the holes of the steel column foundation are accurately introduced and connected with the anchor bolts, improving the stability of the introduction process.

[0025] Example 2: Figure 1 - Figure 4 As shown, a locking bolt 15 is threaded through the bottom surface of the positioning plate 11, a limiting hole 32 is opened through the top surface of the fixing frame 3, the inner wall of the limiting hole 32 is movably connected to the outer wall of the guide rod 2, an adjusting bolt 31 is threaded through the center of the top surface of the fixing frame 3, the top of the connecting plate 4 is snapped into the outer wall of the adjusting bolt 31, a connecting groove 33 is opened on the outer wall of the fixing frame 3, the connecting plate 4 is movably connected to the inner wall of the connecting groove 33, a limiting groove 41 is opened through the upper outer wall of the connecting plate 4, a locking bolt 34 is movably connected to the inner wall of the limiting groove 41, and one end of the locking bolt 34 is threaded to the inner wall of the connecting groove 33.

[0026] The overall effect of this embodiment is that, by setting the locking bolt 15, the user can easily adjust the length of the positioning plate 11 to adapt to steel column foundations of different specifications. By rotating the adjusting bolt 31 and the locking bolt 34, the bearing height of the connecting plate 4 can be adjusted, so that the steel column foundation can be better lowered onto the connecting plate 4.
