Description

Technical Field

[0001] The utility model relates to the technical field of novel steel structure construction, and more particularly to a novel steel structure construction support frame. Background Art

[0002] In existing steel structure construction technology, support frames are key auxiliary equipment, and their design and function directly affect the efficiency, safety, and flexibility of construction. However, most support frames on the market currently have many limitations and cannot meet the diverse needs of modern construction. These problems not only reduce construction efficiency, but may also affect project quality and safety, and thus have a negative impact on the progress and cost of the entire construction project. Traditional steel structure construction support frames usually adopt a fixed structural design, and their height and top angle cannot be changed once manufactured. This rigid design is inadequate in the face of complex and changing construction environments: it has poor adaptability and cannot adjust the support height and angle according to the requirements of different building structures, which limits its scope of application and is inefficient. When support at different heights or angles is required, the entire support frame often needs to be replaced, increasing time and labor costs. The fixed structure lacks accuracy and cannot accurately match the complex steel structure shape, which may lead to unstable support or uneven force. Inventory management is difficult, and it is necessary to stock support frames of multiple specifications, increasing warehousing costs and management difficulties.

[0003] Secondly, some manufacturers have realized this problem and started to introduce the function of adjustable top angle in the support frame design. This is undoubtedly an improvement, but new problems follow: the connection is complicated, the connection between the angle adjustment components and the support frame body is often too complicated, and the installation and disassembly require a lot of time and effort. It is tool-dependent. Many designs require the use of special tools to complete the installation and disassembly of the angle adjustment components, which increases the complexity of on-site operations and limits flexibility. When the angle adjustment function is not needed, the relevant components cannot be quickly removed, resulting in unnecessary weight and volume increase, maintenance difficulties, and complex connection structures increase the difficulty of maintenance, which may lead to a shortened equipment life and operational risks. The cumbersome installation and disassembly process increases the risk of operational errors and may affect construction safety.

[0004] Finally, some manufacturers try to solve the above problems by designing quick installation and disassembly mechanisms. However, these designs often pursue convenience too much and ignore the key factor of structural stability: insufficient strength. In order to achieve quick connection, simplified locking mechanisms are often used, which leads to reduced overall structural strength and the risk of accidental unlocking. Simple locking devices are easily loosened or fallen off due to vibration or external force, which seriously threatens construction safety and limited load-bearing capacity. Insufficient structural stability limits the maximum load-bearing capacity of the support frame, reduces its scope of application, and has a short service life. The existence of these problems seriously restricts the practicality and reliability of the new steel structure construction support frame. They not only affect construction efficiency and quality, but also may bring safety hazards. Utility Model Content

When the connecting steel 30 is adjusted to a suitable angle, all the corresponding locking bolts 35 are rotated in the opposite direction, so that the locking bolts 35 and the corresponding sliding blocks 36 press and fix the corresponding components, thereby achieving the purpose of adjusting the overall top angle of the equipment and effectively improving the applicability of the equipment.
