[0001] The utility model relates to the technical field of steel structure construction auxiliary equipment, in particular to a limiting mechanism and a limiting device for installing a steel structure longitudinal beam. Background Art

[0002] During the installation and construction of steel structure longitudinal beams, due to their long structure and heavy weight, they are generally installed through hoisting operations. During the hoisting operation, the steel structure longitudinal beams may sway left and right due to wind force, tension and other reasons, resulting in an inability to quickly stabilize and difficult to install in the designed position.

[0003] In the prior art, there are generally two methods to stabilize the longitudinal beams of steel structures. One is to stabilize them by manually pulling guy ropes, and the other is to apply supports, corner blocks, etc. for limited stabilization to meet construction requirements.

[0004] However, the method of stabilizing by manually pulling guy ropes is rather cumbersome and requires force analysis to apply tension at appropriate positions to balance the longitudinal beams of the steel structure. This has the problems of cumbersome operation and complicated balancing process. The method of applying supports and corner blocks requires welding or bolting to the existing steel structure, which may affect the existing structure. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] The embodiments of the present application provide a limiting mechanism and a limiting device for the installation of longitudinal beams of steel structures, which can solve the problem that the method of stabilizing by manually pulling wind ropes in the prior art is rather cumbersome and requires force analysis to apply tension at appropriate positions to balance the longitudinal beams of the steel structure, resulting in cumbersome operation and a complicated balancing process. The application of supports and corner blocks requires welding or bolting to the existing steel structure, which may affect the existing structure.

[0031] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, on the one hand, the present application provides a limiting mechanism for installing a longitudinal beam of a steel structure, which includes:

[0032] Adsorption connector 1, which is used to be adsorbed on the existing steel structure 2;

[0033] A mounting bracket 3 is provided on the adsorption connector 1 and extends to the outside of the mounting area of ​​the steel structure 4 to be mounted;

[0034] The limiting member 5 is provided on the portion of the mounting bracket 3 extending to the outside of the mounting area of ​​the steel structure 4 to be mounted. The limiting member 5 is used to abut against the side surface of the steel structure 4 to be mounted.

[0035] When using the limiting mechanism for installing a steel structure longitudinal beam, the adsorption connector 1 is adsorbed onto the existing steel structure 2, the mounting bracket 3 is set on the adsorption connector 1 and extends to the outside of the mounting area of ​​the steel structure 4 to be installed, and the limiting member 5 is set on the portion of the mounting bracket 3 extending to the outside of the mounting area of ​​the steel structure 4 to be installed. The limiting member 5 is used to abut the side of the steel structure 4 to be installed. At least two members with a limiting function can be used to fix the horizontal movement of the steel structure longitudinal beam. Since the adsorption connector 1 is adsorbed on the existing steel structure 2 and the limiting member 5 is used to abut the side of the steel structure 4 to be installed, the limiting function can be completed without causing structural damage to the existing steel structure 2. The operation is simple, which solves the problem of the existing technology of manually pulling the wind rope to stabilize the beam, which is relatively cumbersome and requires force analysis to apply tension at the appropriate position to balance the steel structure longitudinal beam. The problem of cumbersome operation and complicated balancing process is solved. The method of applying supports and corner blocks requires welding or bolting to the existing steel structure, which may affect the existing structure.

[0036] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, in some optional embodiments, the limit member 5 is a roller structure, the rolling surface of the limit member 5 is used to abut against the side of the steel structure 4 to be installed, and the rolling direction of the rolling surface of the limit member 5 is the same as the installation direction of the steel structure 4 to be installed.

[0037] In this embodiment, the limit member 5 is a roller structure, and the rolling surface of the limit member 5 is used to abut against the side of the steel structure 4 to be installed, and the rolling direction of the rolling surface of the limit member 5 is the same as the downward installation direction of the steel structure 4 to be installed, thereby reducing the friction between the limit member 5 and the steel structure 4 to be installed, and preventing excessive wear on the contact surface between the limit member 5 and the steel structure 4 to be installed, thereby affecting the installation effect.

[0038] like Figure 1 and Figure 2 As shown, in some optional embodiments, the mounting bracket 3 includes at least one L-shaped frame, the short side of the L-shaped frame is perpendicular to the adsorption connector 1 and connected to the adsorption connector 1, and a limit member 5 is provided on the long side of the L-shaped frame.

[0039] In this embodiment, the structure of the mounting bracket 3 is specifically described. The mounting bracket 3 includes at least one L-shaped frame. The short side of the L-shaped frame is perpendicular to the adsorption connector 1 and is connected to the adsorption connector 1. A limiting member 5 is provided on the long side of the L-shaped frame. The structure is simple and easy to implement. Multiple L-shaped frames can be arranged at intervals along the downward installation direction of the steel structure 4 to be installed, further improving the guiding and limiting effect, improving the effect of the limiting mechanism for installing the steel structure longitudinal beam, and improving stability.

[0040] like Figure 1 and Figure 2 As shown, in some optional embodiments, the sum of the projected length of the adsorption connector 1 on the long side and the length of the limiting member 5 along the axial direction is less than the length of the long side.

[0041] In this embodiment, the sum of the projected length of the adsorption connector 1 on the long side and the length of the limiting member 5 along the axial direction is less than the length of the long side, which facilitates the setting of the limiting member 5 on the long side and abutting against the side of the steel structure 4 to be installed, leaving sufficient setting space.

[0042] like Figure 1 、 Figure 2 and Figure 3 As shown, in some optional embodiments, the limiting member 5 includes at least one limiting roller, which is rotatably mounted on the long side of the L-shaped frame.

[0043] In this embodiment, the structure of the limiting member 5 is specifically described. The limiting member 5 includes at least one limiting roller, which is rotatably mounted on the long side of the L-shaped frame. The structure is simple and easy to implement, and multiple limiting rollers can be arranged at intervals on the long side of the L-shaped frame to further improve the guiding limiting effect, improve the effect of the limiting mechanism for installing the steel structure longitudinal beam, and improve stability.

[0044] like Figure 1 and Figure 2 As shown, in some optional embodiments, a limiting structure corresponding to the limiting roller is provided on the long side, and the limiting structure is used to limit the relative displacement between the limiting roller and the long side along the axial direction of the limiting roller.

[0045] In this embodiment, a limiting structure corresponding to the limiting roller is provided on the long side. The limiting structure is used to limit the relative displacement between the limiting roller and the long side along the axial direction of the limiting roller, preventing the limiting roller from moving on the long side, thereby improving the stability of the limiting mechanism used for the installation of the steel structure longitudinal beam.

[0046] like Figure 1 and Figure 2 As shown, in some optional embodiments, the limiting structure includes two limiting components 6, both of which are sleeved on the long side and can be fixed relative to the long side, and the two limiting components 6 are respectively abutted against the two ends of the limiting part 5.

[0047] In this embodiment, the structure of the limiting structure is specifically described. The limiting structure includes two limiting components 6. The two limiting components 6 are both mounted on the long side and can be fixed relative to the long side. The two limiting components 6 are respectively abutted against the two ends of the limiting part 5. The structure is simple and easy to manufacture.

[0048] In some optional embodiments, the limiting structure is a limiting groove provided on the long side, and the length of the limiting groove matches the axial length of the limiting member 5 .

[0049] In this embodiment, another setting mode of the limiting mechanism is provided. The limiting structure is a limiting groove set on the long side. The length of the limiting groove matches the axial length of the limiting member 5, and the limiting member 5 is limited in the form of a stepped shaft.

[0050] In some optional embodiments, the mounting bracket 3 includes two L-shaped frames spaced apart along the mounting direction of the steel structure 4 to be mounted.

[0051] In this embodiment, the mounting bracket 3 includes two L-shaped frames spaced apart along the installation direction of the steel structure 4 to be installed, which reduces the space occupied by the mounting bracket 3 while ensuring the effectiveness of the limiting mechanism for installing the steel structure longitudinal beam and improving stability.

[0052] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, on the other hand, the present application also provides a limiting device for installing a steel structure longitudinal beam, which includes at least four of the above-mentioned limiting mechanisms for installing a steel structure longitudinal beam.

[0053] When using the limiting mechanism for installing a steel structure longitudinal beam, the adsorption connector 1 is adsorbed onto the existing steel structure 2, the mounting bracket 3 is set on the adsorption connector 1 and extends to the outside of the mounting area of ​​the steel structure 4 to be installed, and the limiting member 5 is set on the portion of the mounting bracket 3 extending to the outside of the mounting area of ​​the steel structure 4 to be installed. The limiting member 5 is used to abut the side of the steel structure 4 to be installed. At least two members with a limiting function can be used to fix the horizontal movement of the steel structure longitudinal beam. Since the adsorption connector 1 is adsorbed on the existing steel structure 2 and the limiting member 5 is used to abut the side of the steel structure 4 to be installed, the limiting function can be completed without causing structural damage to the existing steel structure 2. The operation is simple, which solves the problem of the existing technology of manually pulling the wind rope to stabilize the beam, which is relatively cumbersome and requires force analysis to apply tension at the appropriate position to balance the steel structure longitudinal beam. The problem of cumbersome operation and complicated balancing process is solved. The method of applying supports and corner blocks requires welding or bolting to the existing steel structure, which may affect the existing structure.

[0054] In this example, four of the above-mentioned limiting mechanisms for installing steel structure longitudinal beams are included and are respectively arranged on the outside of the four corners of the steel structure 4 to be installed.
