Description

Technical Field

[0001] The utility model relates to the technical field of cantilever external frame supports, in particular to an adjustable cantilever external frame support used in prefabricated construction. Background Art

[0002] The assembled steel cantilever external frame support system is a new energy-saving and efficient construction method in building construction technology. Because the process is direct, material-saving and easy to construct, it has gradually been recognized and applied in high-rise building construction in recent years. The steel cantilever external frame support device currently commonly used has two mounting holes for the main load-bearing component (fixed base plate) of the support, and they are set in the center, resulting in a very limited ability of the support to withstand bending moments. Moreover, when the support of the above structure encounters an uneven wall, it cannot be adjusted, resulting in the I-beam part of the cantilever external frame support not being in a horizontal state, which not only brings difficulties to construction, but also the support in a non-horizontal state has a greater safety hazard.

[0009] Furthermore, the upper suspension seat includes an upper connecting plate and a vertical lifting ear arranged on the upper connecting plate; wherein a reserved hole for connecting the longitudinal pull rod is opened on the vertical lifting ear; wherein a plurality of upper assembly holes for fixing to the upper suspension seat are symmetrically opened on the upper connecting plate.

[0010] Furthermore, the longitudinal pull rod is a basket screw, one end of which is connected to the reserved hole through an upper pull rod, and the other end of which is connected to the upper hanging seat on the I-beam through a lower pull rod.

[0011] Furthermore, two horizontal connecting seats are symmetrically arranged on the side of the I-beam, and the horizontal connecting seat includes two ear plates and a connecting shaft connecting the two ear plates.

[0012] Furthermore, the horizontal tie rod is a basket screw, one end of which is connected to the horizontal connecting seat on the adjacent I-beam side wall through the first horizontal tie rod, and the other end of which is connected to the horizontal connecting seat on another adjacent I-beam side wall through the second horizontal tie rod.
