Detachable anchor device for cantilever section steel beam

Abstract

The invention discloses a detachable anchor device for a cantilever section steel beam, which comprises a bottom plate arranged on the bottom surface of a concrete plate and a pressure plate for fixing the cantilever section steel beam on the top surface of the concrete plate. A plastic thin film is paved on the bottom plate and is isolated from the concrete plate; four screws are respectively and vertically fixed on four corners of the bottom plate; the screws pass through the concrete plate and sleeves are sleeved outside the screws to separate the screws from the concrete plate; the four corners of the pressure plate are sleeved on the screws; and nuts are screwed on the screws; and the pressure plate is pressed down by the nuts. The anchor device disclosed by the invention is detachable, can be turned around for use, has no waste and has high safety performance; and the using safety of an outer frame is ensured.

Description

technical field [0001] The invention relates to a fixing device for cantilevered steel girders. Background technique [0002] The form of construction scaffolding presents a diversified development trend, and cantilevered scaffolding is widely used for its large operating range, material saving, low cost, simple and convenient erection, safety and reliability. The traditional cantilever frame uses steel pipes as the supporting mechanism, which has poor stability. In recent years, the cantilever frames are all supported by section steel, and the fixing methods are different, which greatly affects the economy and safety of the cantilever frame support. variable. [0003] Cantilevered steel beams are usually fixed with traditional round steel collars, which are irregular in shape and I-beams are difficult to install; the collars and ribs need to be positioned by electric welding when pre-embedded; gas cutting operations by professional workers are required for dismantling; Fi...
