Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, and more specifically, particularly to an adjustable steel structure support positioning device. Background Art

[0002] The steel structure support node is the most critical part of the structural engineering. The accuracy of its construction positioning and the reliability of the support structure connection directly affect the smooth installation and engineering safety of the project. However, due to the limitations of construction methods and construction accuracy, it is particularly difficult to accurately install and position and effectively connect the steel structure support nodes supported on the concrete structure. The steel structure support nodes need to be anchored and connected to the concrete structure through anchor bolts or embedded parts. For the support nodes where a single anchor bolt is inserted into the concrete structure separately, the steel support is generally slightly positioned and adjusted before tightening the anchor bolt, and the 50mm thick concrete secondary grouting technology is often used to repair the connection between the support and the concrete structure. However, due to the low applicability and poor adjustability of this engineering practice, a steel structure support positioning device that is easy to adjust came into being.

[0003] The invention patent application with the publication number of CN116517121A discloses an adjustable positioning device for a steel structure support node, including a concrete structure, a positioning component and an adjustment structure. The concrete structure is connected with a plurality of positioning components, the positioning component is connected with an adjustment structure, the adjustment structure includes a positioning sleeve, the positioning sleeve is plugged with the positioning component, the positioning sleeve is rotatably connected with a transverse control bolt, the transverse control bolt is threadedly connected with a slider, the slider is slidably connected to the adjustment part through a slide groove, the bottom end of the adjustment part is threadedly connected with a vertical control bolt, the top of the vertical control bolt is rotatably connected with a bottom tray, and the top of the bottom tray is connected with a positioning sleeve. The adjustment plate can be fine-tuned by adjusting the transverse control bolt and the vertical control bolt, the support is connected to the adjustment plate and the support is fixed by cement irrigation. However, the disadvantage is that the positioning component and the adjustment structure are both located on the axial outer side of the concrete structure. When the installation and adjustment are completed and poured, cement needs to be poured inside the adjustment part, which not only complicates the process, but also increases the amount of cement and changes the original structure of the concrete structure.

[0029] In this embodiment, the longitudinal adjustment rod 4 is a screw rod, and the longitudinal adjustment assembly includes a longitudinal adjustment nut 7 and a sliding sleeve 8. The longitudinal adjustment nut 7 is sleeved on the longitudinal adjustment rod 4 and is threadedly connected to the longitudinal adjustment rod 4. The sliding sleeve 8 is arranged on the longitudinal adjustment rod 4. The sliding sleeve 8 and the longitudinal adjustment nut 7 are coaxially arranged and horizontally rotatably connected to each other. A sleeve 9 is horizontally fixed on the outside of the sliding sleeve 8.
