Description

Technical Field

[0001] This utility model belongs to the field of building construction equipment technology, specifically relating to an adjustable figure-eight support device for lightweight building construction machines. Background Technology

[0002] In the construction industry, a building construction machine is an integrated equipment platform, mainly composed of a support power system, a steel platform system, a hanging frame, and a protection system. Internally, it forms a factory-like assembly line, capable of completing tasks such as steel column hoisting, rebar tying, formwork erection, concrete pouring, and concrete curing layer by layer. To ensure comprehensive coverage of the construction area, a building construction machine typically needs to cover a construction area of ​​3 to 4 floors. Therefore, the column height of a building construction machine is relatively high.

[0003] Lightweight construction machines, compared to traditional heavy-duty machines, are significantly lighter, resulting in smaller column cross-sections, which can affect their lateral stiffness. Therefore, to ensure structural stability and construction safety, it is necessary to enhance lateral bracing measures. When installing these lateral braces, they need to accommodate errors during manufacturing and assembly, as well as variations in structural dimensions. However, traditional installation methods have relatively limited adjustability, making it difficult to meet the adjustment needs of various types and sizes of projects. This not only increases the difficulty of on-site installation and dismantling but also limits the product's versatility and reusability. Therefore, developing an adjustable lateral bracing system is crucial for improving the practicality and economic efficiency of lightweight construction machines. Utility Model Content

[0032] The adjustable figure-eight brace device provided by this utility model includes an upper figure-eight horizontal brace 4, a figure-eight diagonal brace 5, a lower figure-eight horizontal brace 6, a figure-eight brace mounting base 7, and a tower column connector 8. In this embodiment, the figure-eight brace mounting base (7) is fixed to the end of the tower column away from the tripod (2) by a detachable connection, and the tower column connector 8 is fixed to the end of the tower column 3 near the tripod 2 by welding. The tower column connector 8 includes two parallel steel plates, each with holes for connection, specifically as follows: Figure 8 As shown.

[0033] In the device provided by this utility model, the figure-eight brace mounting base 7 is detachably connected to the tower column 3 at the position where the figure-eight upper horizontal brace 4 needs to be installed. The figure-eight brace mounting base 7 provided in this embodiment is as follows: Figure 7As shown, the figure-eight brace mounting base 7 includes a base plate 71, two upright plates 72, and four stiffening plates 73.
