Description

Technical Field

[0001] This utility model belongs to the field of precast column installation technology, and in particular relates to an auxiliary device for hoisting and installing precast columns. Background Technology

[0002] A cup-shaped foundation is a type of independent concrete foundation with a cup-shaped hole at the top for inserting a precast column. After the precast column is inserted into the cup-shaped hole, the gap between the precast column and the cup-shaped hole needs to be filled and compacted with fine aggregate concrete with a strength one grade higher than that of the foundation concrete.

[0003] Currently, precast columns are typically hoisted and installed using large lifting equipment. During installation, construction workers need to manually push the precast column from its base to repeatedly adjust its position for positioning. This process is difficult and prone to accidents. Therefore, it is necessary to design an auxiliary device for hoisting and installing precast columns to solve these problems. Utility Model Content

[0004] The main purpose of this utility model is to propose an auxiliary device for hoisting and installing precast columns, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A precast column hoisting and installation auxiliary device is used to fix it to the top of a cup-shaped foundation. The device includes a lower frame and an upper frame, which are fixedly connected by four vertical angle steels. The lower frame, upper frame, and four vertical angle steels are connected to form a frame-tube structure. The diameter of the frame-tube structure is the same as the size of the precast column. The upper and lower frames cover the four sides of the precast column, and the four vertical angle steels cover the four edges of the precast column. A cup-shaped frame, which is larger at the top and smaller at the bottom, is fixed to the top of the upper frame. The upper part of the cup-shaped frame is larger than the precast column and has levers installed around its perimeter. A cylinder is fixed to the middle of the levers and is movably fitted onto the cup-shaped frame. The bottom of the levers has rollers.

[0007] Preferably, both the lower and upper frames are welded from four channel steels, wherein the lower frame is welded in a grid structure, and the protruding part is fixedly connected to the cup-mouth foundation by expansion bolts.

[0008] Preferably, a trapezoidal brace is also connected between the lower frame and the upper frame, and a trapezoidal brace is provided between each adjacent vertical angle steel.

[0009] Preferably, the cup rim frame includes a rectangular frame with a diameter larger than the precast column, and the four corners of the rectangular frame are connected to the upper frame by inclined connecting rods.

[0010] Preferably, both the rectangular frame and the connecting rod are made of round steel.

[0011] This utility model provides an auxiliary device for hoisting and installing precast columns, which has the following beneficial effects:

[0012] 1. This auxiliary device is made of materials commonly used on construction sites, such as channel steel, angle steel, and round steel. It has a simple structure and the materials are readily available.

[0013] 2. When using this auxiliary device, first position the device according to the cup opening at the top of the cup base, so that the diameter of the frame cylindrical structure is located in the center of the cup opening. Align the precast column with the diameter of the upper frame using the levers around the perimeter. Then continue to lower the precast column. The precast column is lowered along the frame cylindrical structure into the cup opening, so that the precast column is placed in the center of the cup opening. The positioning is accurate and the operation is simple.

[0014] 3. The downward lever can push the precast column to move, making the operation safe for construction personnel. The roller at the bottom of the lever supports the precast column and also prevents it from being scratched. Attached Figure Description

[0024] Example

[0025] Reference Figure 1-4A precast column hoisting and installation auxiliary device is used to fix it to the top of a cup-shaped foundation 100. The precast column hoisting and installation auxiliary device includes a lower frame 1 and an upper frame 2. The lower frame 1 and the upper frame 2 are fixedly connected by four vertical angle steels 3. The lower frame 1, the upper frame 2, and the four vertical angle steels 3 are connected to form a frame cylindrical structure. The diameter of the frame cylindrical structure is the same as the size of the precast column 200. The upper frame 2 and the lower frame 1 are used to cover the four sides of the precast column 200. The four vertical angle steels 3 are used to cover the four edges of the precast column 200. A cup-shaped frame 4 with a larger top and a smaller bottom is fixed to the top of the upper frame 2. The upper part of the cup-shaped frame 4 is larger than the precast column 200 and levers 5 are installed around its perimeter. A cylinder 51 is fixed to the middle of the lever 5. The cylinder 51 is movably fitted on the cup-shaped frame 4. The bottom of the lever 5 has rollers 52.

[0026] In one specific implementation, both the lower frame 1 and the upper frame 2 are welded from four channel steels, wherein the lower frame 1 is welded in a grid structure, and the protruding part is fixedly connected to the cup base 100 by expansion bolts.

[0027] In one specific implementation, a trapezoidal brace 6 is also connected between the lower frame 1 and the upper frame 2, and a trapezoidal brace 6 is provided between each adjacent vertical angle steel 3. The overall strength of the frame tube structure can be increased by the trapezoidal brace 6.

[0028] In one specific implementation, the cup frame 4 includes a rectangular frame with a diameter larger than that of the precast column 200, and the four corners of the rectangular frame are connected to the upper frame 2 by inclined connecting rods.

[0029] In one specific implementation, both the rectangular frame and the connecting rod are made of round steel.

[0030] This auxiliary device is made entirely of commonly used materials on construction sites, such as channel steel, angle steel, and round steel. It has a simple structure and readily available materials. In use, the auxiliary device is first positioned according to the cup-mouth hole 101 at the top of the cup-mouth foundation 100, ensuring the diameter of the frame's cylindrical structure is centered within the cup-mouth hole 101. Then, the lower frame 1 is fixed to the cup-mouth foundation 100 using expansion bolts, completing the fixation of the auxiliary device. After the auxiliary device is fixed, a crane lifts the precast column 200, which is lowered onto the cup-mouth frame 4. The upper part of the cup-mouth frame 4 is larger than the precast column 200, providing space for the lever 5 to move. Pressing down on the lever 5 moves the precast column 200, ensuring safe operation for construction personnel. The roller 52 at the bottom of the lever 5 supports the precast column 200 while preventing scratches. The precast column 200 is aligned with the diameter of the upper frame 2 using the levers 5 around it. Then, the precast column 200 is lowered down along the cylindrical structure of the frame into the cup opening 101, so that the precast column 200 is placed in the exact center of the cup opening 101. The positioning is accurate and the operation is simple. The precast column 200 is encased in the cylindrical structure of the frame, which can achieve temporary fixation. Finally, concrete is poured into the gap between the precast column 200 and the cup opening 101 to permanently fix the precast column 200.
