technical field

The utility model relates to the technical field of hoisting equipment and structures, in particular to a detachable indoor crane used for buckling restraint support.

Background technique

Buckling-restrained brace is a new type of energy-dissipating brace, which is widely used in various new buildings and reinforcement projects. The hoisting and installation of the outer frame supports mostly use outdoor tower cranes for high-altitude operations, but there is currently no special lifting equipment for the hoisting of indoor small buckling restrained supports.

The existing indoor cranes mainly include bridge cranes, gantry cranes and semi-gantry cranes, which can realize the free movement of indoor components in the vertical and horizontal directions, but due to the complex structure, poor portability and high cost, they cannot be applied to many Indoor support installation of high-rise buildings.

In actual engineering, the installation of indoor small-scale buckling-restrained supports is mostly carried out by temporary and simple scaffolds equipped with electric hoists for hoisting. The stability is extremely poor, and there are great hidden dangers in construction safety.

detailed description

The utility model will be described in further detail below in conjunction with the accompanying drawings, which is an explanation of the utility model rather than a limitation.

The utility model is a detachable indoor crane for buckling restraint support, including three standardized assembly components and some connecting components, as shown in Figure 1, the upper component set on the top has a fixed electric hoist 1, and the bottom set is stable The chassis, the middle assembly is assembled by four connecting steel pipes 6 and four first reinforcing cross bars 5. It can be disassembled, easy to move, and has strong stability. By assembling different types and quantities of intermediate components, it can adapt to different indoor heights. Compared with the existing technology, it can better meet the actual needs of the installation of buckling-constrained braces for indoor frames of multi-high-rise buildings.

Specifically, as shown in Figure 2a and Figure 2b, the upper assembly is assembled from electric hoist 1, I-beam 2, first column 3 and beam 4; as shown in Figure 3a and Figure 3b, the middle assembly is made of square steel pipe The first reinforcing cross bar 5 and the connecting steel pipe 6 are connected by bolts; The arranged cross bar 10 provides stable support, and the second reinforced cross bar 7 adopting a square steel pipe is responsible for connection. The first upright column 3 in the upper assembly and the cross bar 10 on the chassis are correspondingly connected by eight chain rods 11 to strengthen the connection force between different upper assemblies and the base. The first column 3, several connecting steel pipes 6 and the second column 9 are assembled and fixed in the vertical direction successively to form a frame inside as a hoisting space.
