Description

Technical Field

[0001] The utility model relates to the technical field of steel structure construction components, in particular to a steel structure hoisting and assembling fulcrum adjustment device. Background Art

[0002] During the construction of steel structures, the setting of fulcrums for hoisting components is a key step in ensuring construction safety and efficiency. Traditional methods of setting fulcrums usually use welding technology to connect and fix the supports to embedded parts. However, this method has some problems, such as cumbersome procedures, material waste, impact on the aesthetics of the structure, and the need to remove welded parts after construction is completed, all of which may affect the overall integrity and aesthetics of the steel structure. In addition, for components that cannot be lifted by lifting machinery, the traditional method uses lifting equipment for lifting, and the fulcrum setting is fixed and cannot be adjusted, which limits its applicability to different steel beams. Utility Model Content

[0022] The following is a clear and complete description of the technical solution of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention. Example

[0023] See also Figure 1 - Figure 4 The figure shows a prefabricated steel structure lifting fulcrum system, comprising the following components: a fulcrum rod 1, a width adjustment rod A2, a height adjustment rod B3, a vertical movable rod 4, and a transverse movable rod 5. The fulcrum rod 1 supports the lifting equipment, while the width adjustment rod A2 and the height adjustment rod B3 are connected to the fulcrum rod 1. The vertical movable rod 4 and the transverse movable rod 5 are connected to the width adjustment rod A2 and the height adjustment rod B3, respectively, to facilitate fixing to steel beams of different sizes and adjusting height and width.

[0024] The width adjustment rod A2 and the height adjustment rod B3 are connected by a sleeve 7. The vertical movable rod 4 and the transverse movable rod 5 are also connected by a sleeve 7. The sleeve 7 is made of 5mm thick steel plate. The transverse movable rod 5 is welded to the sleeve 7 by four round steel bars with a diameter of 10cm.

[0025] The height adjustment rod B3 and the fulcrum rod 1 are both made of 2.5m and 2m long I-beams, while the width adjustment rod A2 is made of 1.5m long I-beams. The ends of the vertical movable rod 4 and the horizontal movable rod 5 are connected by 5mm thick sleeves 7 and fixed with bolts through the center holes.

[0026] Width adjustment rod A2 and height adjustment rod B3 are equipped with scale holes on the I-beam to accommodate various beam sizes. Vertical movable rods typically have holes every 50 cm for height adjustment, while the center crossbar has width holes every 50 cm.

[0027] The movable rods are connected to the locating holes through the bolt holes in the connecting sleeve 7 using high-strength bolts 8. Once the assembly is in place, install the transverse movable rod 5 and secure the vertical movable rod 4, transverse movable rod 5, height adjustment rod B3, and transverse movable rod 5. This is secured by connecting the locating holes in the vertical movable rod 4 and height adjustment rod B3 to the bolt holes in the connecting sleeve 7 of the transverse movable rod 5 using high-strength bolts 8.

[0028] Finally, the diagonal brace 6 is installed on the fulcrum rod 1 and the height adjustment rod B3, and the lifting equipment is installed on the fulcrum rod 1 for trial lifting. After confirming that the device is stably stressed and there is no abnormality, the lifting operation can be carried out.

[0029] During construction, the first step is to determine the specific installation location of the device on the steel beam. This step is crucial, as it directly affects the stability of the device and the reliability of the overall structure. Once the location is determined, the positioning of the locating holes for the width adjustment rod A2 must be determined based on the actual width of the steel beam. This step requires precise measurement and calculation to ensure that the width adjustment rod A2 is accurately fixed in the predetermined position.

[0030] Once the positioning holes for width adjustment rod A2 are located, the next step is to connect the vertical movable rod 4 to the width adjustment rod A2. This step involves fastening the bolt holes in the sleeve 7 of the vertical movable rod 4 to the positioning holes in rod 2 using high-strength bolts 8. High-strength bolts 8 are selected and used to ensure a secure and durable connection to withstand the various loads that may occur during subsequent construction and use.

[0031] After the vertical movable rod 4 is connected and secured to the width adjustment rod A2, the entire assembly must be installed using a lifting device. The selection and operation of the lifting device must strictly adhere to safety regulations to ensure the safety of the construction personnel and the correct installation of the assembly. Once the assembly is in place, the installation of the transverse movable rod 5 begins. This step also requires precise operation and the use of high-strength bolts 8 to ensure a secure connection between the transverse movable rod 5, the vertical movable rod 4, and the height adjustment rod B3.

[0032] After the transverse movable rod 5 is installed, the vertical movable rod 4 and transverse movable rod 5, as well as the height adjustment rod B3 and transverse movable rod 5, need to be secured separately. This is done by connecting the positioning holes of the vertical movable rod 4 and height adjustment rod B3 to the bolt holes of the connecting sleeve 7 of the transverse movable rod 5 using high-strength bolts 8. Precise operation in this step directly affects the overall stability and safety of the device.

[0033] After the device is installed, it is necessary to install a lifting device on fulcrum rod 1 and conduct a test lift. The purpose of this test lift is to check the stability of the device under load and whether there are any abnormalities. During the test lift, the device's response must be carefully observed and any necessary adjustments made. Only after confirming that the device is stable under load and has no abnormalities can the official lifting operation be carried out. This series of construction steps ensures the safe installation and long-term stable operation of the device.

[0034] The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to specific embodiments. Obviously, numerous modifications and variations are possible based on the contents of this specification. These embodiments are selected and described in detail in this specification to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. The present invention is limited only by the claims and their full scope and equivalents.
