[0002] During the construction of prefabricated high-rise buildings, steel columns and steel beams need to be hoisted using special cranes or hoists. During this hoisting operation, the core step requires installers to use walkie-talkies to direct the driver operating the hoisting equipment to gradually lower the I-beam, and to align the bolt holes at the end of the I-beam and the bolt holes on the bracket vertical plate with the bolt holes on the transition connecting plate respectively. Finally, high-strength bolts are used for bolting. During this process, the difficulties involve, firstly, high-altitude operations, with great difficulty in precise hoisting coordination, and the hoisted I-beam being prone to swaying. During this docking process, it is necessary to repeatedly adjust up and down and for personnel to repeatedly confirm, which is time-consuming and laborious, making the docking construction process relatively inefficient.

[0021] Embodiment 1

[0022] Refer to Figure 1 and Figure 2 、 Figure 3 For the auxiliary device for butt joint installation of prefabricated steel structure I-beams, it includes two symmetric clamping bodies (100, 200) on the left and right. The two clamping bodies have basically the same structure. Specifically, at the splicing and butt joint surfaces of the clamping body, there are protrusions and depressions for quick and accurate positioning. Such protrusions and depressions can be positioning pins and positioning pin holes, or other similar positioning structures. In this embodiment, they are stack-shaped protrusions and depressions.

[0023] Refer to Figure 4, the clamping body 100 is viewed from the vertical plane, with the upper part being the fixing part 110, the middle part being the clamping part 120, and the lower part being the opening part 130. The vertical plane is a T-shaped cross section, and viewed from the horizontal plane, the T-shaped slot formed by the two clamping bodies is along the horizontal plane, from one end to the other end, respectively, the fixing section A, the sliding section B, and the temporary storage section C. In the fixing section A, the fixing part 110 is matched through the stack-shaped protrusions and depressions 112, and is provided with bolt holes, and the two clamping bodies are connected into one after being fastened with the fastening bolts, that is, the cross section is a T-shaped slot, which is used for clamping and matching with the upper flange of the corbel. Furthermore, a horizontal bolt hole is provided on the fixing part, and the fixing part is fixed to the bolt hole on the upper wing plate of the corbel by bolts, that is, under the fastening action of the fastening bolts, the fixing part and the upper wing plate of the corbel are quickly locked and clamped, and the clamping body is temporarily fixed to the corbel through this structure.

[0024] The fixed section is a T-shaped structure in cross section, and part of the structure of the fixed section extends to the outside of the corbel, that is, extends to the sliding section B, forming an outwardly extending structure for bearing the I-beam end connected to the corbel.

[0025] The cross section of the sliding section B is a T-shaped sliding groove.

[0026] The temporary storage section is an upwardly open trumpet structure 111, which is a temporary support point for the I-beam, providing support for the horizontal point and also providing a horizontal reference for it. The trumpet design in the temporary storage section enables the I-beam to be quickly straightened during the docking process, improves the docking efficiency of the I-beam during the high-altitude hoisting operation, and provides a guide platform for alignment, which significantly improves the docking quality.

[0027] After the clamping body is assembled, high-strength bolts are connected on one side to form a clamping structure.

[0028] The clamping body is a steel block and is treated for corrosion resistance.

[0029] This embodiment describes a method for installing the upper flange.

[0030] The method of using the device is:

[0031] First, butt the two clamping bodies and temporarily fix them on the bracket 300. When fixing, butt the two clamping bodies through the fastening bolts 310, and use the fastening bolts 310' to butt the clamping body with the reserved bolt holes on the bracket. Fix the device temporarily on the bracket through this process. Then use a crane to hoist the I-beam 400. During the hoisting process, slowly bring the end of the I-beam close to the temporary placement section of the above device. Then, in the suspended state, slowly insert the end of the I-beam 400 into the sliding section of the clamping body. After reaching the position, use the connecting plate 500 to assist in fixing the web and lower flange of the bracket and the I-beam. During the fixing process, high-strength bolts are used. After removing the two clamping bodies, finally use the third connecting plate to assist in fixing the upper flange of the bracket and the I-beam to complete the installation of this node.

[0032] Embodiment 2

[0033] Embodiment 1 is an installation method based on the upper flange. This embodiment is an installation method based on the lower flange. Referring to the figure, butt the two clamping bodies and install them on the lower flange using fastening bolts. When installing the I-beam, first place the end of the I-beam on this temporary placement section and use the sliding method to push it into the docking point. Then use high-strength bolts and transition connecting plates to connect the vertical plate of the bracket and the web of the I-beam. After the fastening is completed, remove the two clamping bodies. Finally, use the transition connecting plate to tightly connect the flange of the I-beam and the horizontal plate of the bracket.

[0034] In this embodiment, when the clamping body 100 is viewed from the vertical plane, the lower part is the fixing part 110', the middle part is the clamping part 120', and the upper part is the opening part 130'. That is, the difference from Embodiment 1 is the installation direction.

[0035] The fixing part 110 is matched through a stack-shaped structure, provided with bolt holes, and after being fastened with fastening bolts, the two clamping bodies are connected into one body. After the two clamping bodies are enclosed, an inverted T-shaped slot is formed, that is, the clamping part 120, which is used for clamping and matching with the lower flange of the bracket. Under the fastening action of the fastening bolts, rapid locking and clamping of the fixing part and the upper flange of the bracket are achieved, and the clamping body is temporarily fixed to the bracket through this structure.

[0036] The above-mentioned sliding section B encloses to form a T-shaped chute.

[0037] The temporary placement section is a flared structure with an upward opening. This section is the temporary support point of the I-beam, providing horizontal support and also providing a horizontal reference.

[0038] The above-described embodiments are only descriptions of the preferred embodiments of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various modifications and improvements made by those skilled in the relevant art to the present utility model shall fall within the protection scope determined by the claims of the present utility model.
