[0002] With the rapid development of my country's infrastructure, the level of safety management in the construction process has gradually improved. Among them, the management of sub-projects with higher risks has become more and more strict. In terms of the erection form of external scaffolding of building units, cantilever scaffolding has gradually replaced ground scaffolding; in terms of the selection of scaffolding materials, ordinary steel pipe type has been replaced by socket-type disc-type. During the construction process, the socket-type disc-type cantilever scaffolding relies on adjustable base supports to adjust the height of the scaffolding and pipe rack, which plays a role in balancing the support frame and the deadweight of the frame and the load of the working layer. It is most used in the construction process of concrete pouring of the facade and plane construction of building units. With the rapid development of new real estate construction and renovation projects in recent years, the use of adjustable base supports has also made great progress.

[0003] When the traditional cantilever scaffolding adjustable base is fixed to the I-beam, on the one hand, the base plate size of the base is fixed, which is inconvenient to adjust according to the width of the I-beam of different specifications, and is prone to slippage or even detachment. It also involves hot work such as welding, which makes it difficult to control the welding quality, and can easily lead to local damage to the I-beam and scaffolding rental materials, posing a more prominent safety hazard. On the other hand, the traditional base fixing device needs to be set in place before the buckle upright is installed, which affects the large-scale simultaneous installation of the scaffolding.

[0004] Based on this, it is necessary to propose a cantilever scaffolding base for construction. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the utility model provides a base support for a cantilever scaffolding for construction, comprising an I-beam and two groups of fixing and clamping devices, the upper side of the fixing and clamping device is a fixing steel plate, the bottom end of the fixing and clamping device is a clamping steel plate, the surface of the fixing steel plate is provided with fixing position bolt holes and a plurality of non-fixing position bolt holes, and the surface of the clamping steel plate is provided with clamping steel plate bolt holes; the fixing steel plate is in contact with the two side flange plates of the I-beam, the clamping steel plate is clamped and fixed to the two side flange plates of the I-beam by fastening bolts, and the two ends of the fixing steel plates of the two groups of fixing and clamping devices are connected by a connecting steel belt.

[0007] Furthermore, two groups of fastening bolts are provided between the fixed steel plate and the clamping steel plate, and the fastening bolts connect the fixed steel plate and the clamping steel plate through the bolt holes of the clamping steel plate and the fixing position bolt holes.

[0008] Furthermore, the two groups of fastening bolts, one group passes through the clamping steel plate bolt holes and fixed position bolt holes of the clamping steel plate and the fixed steel plate from bottom to top, and the other group passes through the clamping steel plate bolt holes and non-fixed position bolt holes of the clamping steel plate and the fixed steel plate from bottom to top. The two groups of fastening bolts are fixedly connected with nuts respectively, the nuts of the fastening bolts are positioned at the bottom, and a connecting steel belt is installed between the nuts and the fixed steel plate.

[0009] Furthermore, there are steel belt bolt holes at both ends of the connecting steel belt, and two groups of fastening bolts pass through the steel belt bolt holes to connect the two groups of fixing clamping devices to form a combined clamping device.

[0010] Furthermore, the nut is located below the clamping steel plate, and the nut is located above the fixing steel plate.
