[0052] Example 1

[0053] This embodiment provides a basement steel column construction device, such as Figures 1 to 9 As shown, it includes: a base frame 1, a supporting structure 3, a lifting structure 4 and a mobile structure 5. The supporting structure 3 is arranged at the top of the base frame 1, and the lifting structure 4 is arranged at the top of the supporting structure 3. The mobile structure 5 is installed on the ground. Specifically, as shown in FIG. Figure 9 As shown, the movable structure 5 includes a guide rail 51 and a drive assembly 52 . The guide rail 51 is laid between the loading end and the unloading end. The drive assembly 52 is installed on the upper surface of the guide rail 51 , and the base frame 1 is fixed on the top surface of the drive assembly 52 .

[0054] When the steel column 2 needs to be moved, guide rails 51 are first laid at the loading and unloading ends, and drive components 52 are installed on the guide rails 51. The base frame 1, support structure 3 and lifting structure 4 are assembled into a whole, and the whole is moved and fixed to the drive component 52. The mobile structure 5 drives the base frame 1 to move toward the loading end. After reaching the designated position, the lifting end of the lifting structure 4 moves downward. The lifting end of the lifting structure 4 is manually hung on the top of the steel column 2. After the installation is completed, the lifting end of the lifting structure 4 moves upward to lift the steel column 2 into a suspended state. The mobile structure 5 drives the base frame 1 and steel column 2 to move toward the unloading end until they reach the construction position. The lifting structure 4 drives the steel column 2 to descend onto the installed steel column 2 for the next construction step. Through the above-mentioned arrangement, the present application lays the guide rail 51 directly in the basement, and utilizes the mobile structure 5 to drive the entire base frame 1 and the steel column 2 to be transported in the basement. Compared with the existing technology, there is no need to drill holes for the wire rope on the upper trestle board or the ceiling, so as to avoid damaging the original structure of the basement. In addition, during the entire process, the steel column 2 is always in a vertical state during the hoisting process, which does not violate the "Ten No-Hanging" principle. In addition, the present application moves the entire base frame 1 as a whole, and uses the guide rail 51 to prefabricate the route. The transport range is large and more flexible, and the overall structure is compact and high in strength. It can be recycled, improves the efficiency of on-site installation, is simple and convenient, greatly reduces costs, and has significant effects.

[0055] Furthermore, the present application can also limit the height of the entire base frame 1 to be less than the height of the basement ceiling after the basement is built, so as to facilitate subsequent maintenance matters after the basement is built.

[0056] Specifically, such as Figures 1 to 9As shown, there are two guide rails 51, which are arranged in parallel. Four drive assemblies 52 are installed on the guide rails 51. The drive assemblies 52 include a mobile platform 521 and a drive member 522. A guide portion adapted for the guide rail 51 is provided at the bottom end of the mobile platform 521. The guide portion is inserted into a groove in the guide rail 51. The drive member 522 is installed on one side of the mobile platform 521. One end of the drive member 522 is connected to the mobile platform 521, and the other end is connected to the guide rail 51. The drive member 522 is a hydraulic pusher used to push the sliding base 1. A first limiter and a second limiter are respectively provided at each end of the guide rail 51. The first limiter is provided on the side of the guide rail 51 near the loading end, and the second limiter is provided on the side of the guide rail 51 near the unloading end. If multiple steel columns 2 need to be installed at different positions, the guide rails 51 can be laid to cover all unloading ends, and second limiters can be installed at different unloading end positions. Improve on-site construction efficiency.

[0057] The four driving components 52 correspond to the four foot positions of the base frame 1, such as Figure 2 and Figure 3 As shown, four supporting tire frames 11 are provided, and the four supporting tire frames 11 are respectively arranged on two guide rails 51. Two supporting tire frames 11 are provided on each guide rail 51. The connecting line between the two supporting tire frames 11 near the loading end and the unloading end is perpendicular to the guide rail 51. Six connecting trusses 12 are provided, and the two ends of the connecting trusses 12 are respectively connected to the two supporting tire frames 11, two of which are fixed at the lower position of the two supporting tire frames 11, and the other four connecting trusses 12 are fixed at the upper ends of the two supporting tire frames 11 and are arranged between any two supporting tire frames 11 to improve the stability of the entire base frame 1.

[0058] like Figure 2 and Figure 3 As shown, the connecting trusses 12 can only be installed on both sides of the supporting cradles 11 parallel to the direction of the guide rails 51. They cannot occupy the area between a single supporting cradle 11, nor can they occupy the area between two supporting cradles 11, which would otherwise block the transportation of the steel columns 2. The top surfaces of the two connecting trusses 12 at the upper end are flush with the top surface of the base frame 1, thereby forming an annular bridging platform.

[0059] like Figure 2 and Figure 4As shown, the support frame 31 is fixed on the top surface of the annular lap platform, and two support rods 32 are provided. The two support rods 32 are relatively fixed on the annular lap platform, and the two support rods 32 are arranged in parallel. The two ends of the support rods 32 are respectively overlapped on the opposite sides of the support frame 31; the two support rods 32 are arranged in the middle of the support frame 31, that is, the two support rods 32 are at the same positive distance from the center of the support frame. Specifically, the length direction of the support rod 32 is perpendicular to the length direction of the guide rail 51. This avoids the lifting member 41 from sliding along the sliding direction during the movement, causing the steel column 2 to shake in a large range, and then causing safety problems such as the steel column 2 falling, thereby improving the safety index.

[0060] The ends of the lifting beam 33 are respectively fixed to the two support rods 32. A mounting hole is opened in the middle of the lifting beam 33. The lifting member 41 is vertically fixed to the top surface of the lifting beam 33, and can also be fixed in the mounting hole. The lifting member 41 is a hydraulic lifter, and the connecting member 42 is a thicker steel wire rope. One end of the connecting member 42 is connected to the lifting member 41, and the other end is connected to the sling body 431 of the lifting sling 43. The sling body 431 is square, with lifting ears set at the four corners of the bottom. The sling 432 is a steel wire rope with a diameter smaller than the connecting member 42. One end of the sling 432 is connected to the lifting ear, and the other end of the sling 432 is fixed to the lifting ears at the four corners of the top of the steel column 2.

[0061] In other practicable embodiments, a stiffening plate 34 may be installed between the lifting beam 33 and the support rod 32. The stiffening plate 34 is connected to the lifting beam 33 and the support rod 32, respectively. Figure 9 As shown, the two stiffening plates 34 are respectively in contact with the outer sides of the two support rods 32 to prevent the lifting member 41 from sliding along the sliding direction during the sliding process.

[0062] The implementation steps of the basement steel column construction device provided in this utility model are as follows:

[0063] S1. Assemble the basement steel column construction device; measure the distance between the loading end and the unloading end, and lay the guide rail 51 between the loading end and the unloading end; and since the locations where steel frames need to be placed in the basement are generally arranged in a linear array, the guide rail 51 can be laid at the unloading end position farthest from the loading end. Set a first limiter at the loading end of the guide rail 51, and set a second limiter at multiple unloading end positions of the guide rail 51. Figure 2 and Figure 3As shown, four support cradles 11 are placed vertically, with connecting trusses 12 fixed between them to form a base frame 1. A support frame 31 is fixed to the bridging platform at the top of the base frame 1. A support rod 32 is fixed to the center of the top of the support frame 31, and a stiffening plate 34 and a lifting beam 33 are fixed to the support rod 32. A lifting member 41 is vertically mounted on the lifting beam 33. Below the lifting member 41 is a connecting member 42, which passes through the mounting hole and extends downward. A lifting sling 43 is fixed below the connecting member 42. Finally, four drive assemblies 52 are placed on the guide rails 51, and the four legs of the assembled basement steel column construction device are installed and fixed corresponding to the four drive assemblies 52.

[0064] S2. The driving member 522 in the mobile structure 5 drives the basement steel column construction device to move toward the loading end until it abuts against the first limit member. S3. The lifting member 41 drives the connecting member 42 to move downward until the lifting sling 43 is close to the steel column 2 to be moved, and the lower end of the hanging member 432 is completely covered on the lifting lug at the top of the steel column 2. After confirming that the fixation is completed, the lifting member 41 drives the connecting member 42 to move upward, thereby raising the steel column 2 to a suspended state; S4. The mobile structure 5 drives the base frame 1 and the steel column 2 to move toward the unloading end until they abut against the second limit member; the lifting structure 4 drives the steel column 2 down to the position to be constructed. S5. After the construction is completed, the lower end of the hanging member 432 can be removed from the lifting lug at the top of the steel column 2.

[0065] This method can install the steel column 2 to be installed, which is affected by the lower part of the trestle, into place by first lifting and then sliding. It does not need to destroy the trestle structure, and there will be no oblique lifting of heavy objects. It can be recycled, improves the efficiency of on-site installation, is simple and convenient, greatly reduces costs, and has significant effects.

[0066] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
