Technical Field

[0001] The utility model belongs to the technical field of grid assembly, and in particular relates to an adjustable positioning device for grid bolt balls. Background Art

[0002] With the continuous development of large-span space structures such as airports, stadiums, and large exhibition centers, grid structures are constantly being used and presenting more and more structural forms. This type of grid structure has the advantages of small spatial force, light weight, high rigidity, and good seismic performance.

[0003] Among them, more and more buildings use L-shaped steel frame structures. During the assembly process of the bolt ball grid, due to the height difference between the two bolt balls, it is necessary to replace the tire frames of different specifications. The existing assembly devices have inaccurate positioning and poor flexibility, which makes it difficult to ensure the quality of grid assembly. Utility Model Content

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A device for adjusting the positioning of a mesh bolt ball comprises a steel pipe scaffold, a support panel is arranged on the top of the steel pipe scaffold, and the support panel moves vertically on the steel pipe scaffold; the device is characterized in that it also comprises a base and a positioning support, the base is fixed on the support panel, the base is provided with a connecting hole, the bottom of the positioning support is threadedly connected in the connecting hole, the top of the positioning support is provided with a slot, a rod is welded in the slot, the end of the rod extends out of the outside of the positioning support, the rods are fixed to each other to form a support frame, the support frame is used to support the mesh bolt ball, and a reinforcement is fixed between the positioning support and the rod.

[0007] Furthermore, the reinforcement adopts a clip, and the bottom of the clip is provided with slot one and slot two, slot one and slot two are connected, the rod is embedded in slot two, and the top of the positioning support is embedded in slot one, so that the clip and the positioning support are embedded and connected, and the clip and the rod are embedded and connected, so that the rod and the positioning support are firmly connected.

[0008] Furthermore, four slots are provided so that the rods form a cross-shaped support frame to support the entire positioning support.

When the jack does not push the support panel, the support panel is supported on the first steel pipe; when the jack pushes the support panel, the support panel moves upward by a set distance, and at the same time the guide rod moves upward in the guide hole, the guide rod plays a guiding role, making the vertical movement of the support panel more stable.

[0010] Furthermore, a connecting plate is welded to the top of the guide rod, and the connecting plate is connected to the supporting panel via fixing bolts, so that it is convenient to install or remove the supporting panel on the top of the guide rod.

[0011] Furthermore, the second steel pipe is provided with a through hole 1, the bottom of the steel plate 1 is provided with a fixing plate, the fixing plate is provided with a through hole 2, bolt rods are passed through the through hole 1 and the through hole 2, the bolt rods are threadedly connected with locking nuts, and the locking nuts are locked on the outside of the fixing plate, so that the steel plate 1 and the second steel pipe can be detachably connected, which is convenient for maintenance operations on the jack.

[0012] Furthermore, the fixing plate is provided with a groove, the groove is connected to the through hole, and the second steel pipe is embedded in the groove, so that the connection between the fixing plate and the second steel pipe is more secure.

[0013] Furthermore, a second steel plate is fixed between two parallel second steel pipes distributed along the Y-axis direction. The second steel plate is arranged below the first steel plate. The second steel plate is threadedly connected with a tightening bolt, which supports the bottom surface of the first steel plate. The tightening bolt is arranged below the jack. The tightening bolt supports the steel plates together, which can increase the force-bearing capacity of the first steel plate, so that the jack can push the supporting panel.

[0014] Furthermore, a tightening plate is fixed on the top of the tightening bolt, and the cross-sectional area of ​​the tightening plate is larger than the cross-sectional area of ​​the tightening bolt. The tightening plate is tightly attached to the bottom surface of steel plate one, increasing the contact area between the tightening bolt and steel plate one, thereby increasing the supporting area of ​​the tightening bolt on steel plate one.

[0015] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0016] The utility model first moves the support panel vertically on the steel pipe scaffolding, adjusts the height of the support panel, and makes the support frame close to the bolt ball of the grid frame. Then, a force is applied to the end of the rod, and the support frame is rotated, so that the positioning support rotates on the base, and the height of the positioning support is adjusted, and then the height of the support frame is adjusted, so that the support frame supports the bolt ball of the grid frame. The utility model can adjust the support height of the support frame, adjust it to the construction height, and enable the support frame to accurately position the bolt balls of different heights, thereby ensuring the assembly quality of the grid frame.

[0017] Moreover, considering that the thickness of the positioning support is relatively thin, when a force is applied to the end of the rod, the positioning support is prone to deformation. Therefore, the utility model fixes a reinforcement member between the positioning support and the rod to increase the connection strength between the positioning support and the rod, and the force applied to the rod can act on the positioning support through the reinforcement member, thereby avoiding deformation of the positioning support when a force is applied to the end of the rod.
