Wall-attaching support for building construction with falling-prevention mechanisms

Abstract

The invention discloses a wall-attaching support for building construction with falling-prevention mechanisms. The wall-attaching support comprises a vertical plate, wherein supporting bodies are fixedly connected to one side of the lower portion of the vertical plate, and the two ends of a connecting rod are fixedly installed in T-shaped gaps of the supporting bodies through locking nuts respectively; a fixed shaft is fixedly inserted in a bearing inner ring of a supporting bearing, supporting teeth are fixedly connected to the circumference of the outer side of a rotary disc, and arc supporting openings are formed in the upper portions of the supporting teeth. Arc ratchet teeth are fixedly connected to the interiors of annular grooves, reversion-prevention ratchet pawls which are matchedwith the arc ratchet teeth are fixedly connected to the surfaces of one sides of sleeves, and reset springs further sleeve hexagonal prism supporting rods. The upper and lower wall-attaching supportsare connected together, then multiple sets of falling-prevention mechanisms are added at random positions between the upper and lower wall-attaching supports, thus the safety is improved, local stress of the wall-attaching supports is changed, local overload is lowered, and protection is achieved in an all-around way. In the meanwhile, connecting rods are easy to install and detach, the arrangement density of the wall-attaching supports can be lowered, and the cost is lowered.

Description

technical field [0001] The invention relates to the technical field of a wall-attached support, in particular to a wall-attached support with a fall prevention mechanism for building construction. Background technique [0002] The wall-attached support of the climbing frame is an important safety device for the climbing frame. Both the anti-falling device and the anti-overturning device are set on the wall-attached support, which is also the component that bears the load transmission of the climbing frame. Therefore, the connection between it and the building structure is effective. , Reliability is very important. [0003] The wall-attached support has three major components: anti-tilt (guiding wheels installed on both sides), unloading (top support), and anti-fall (trigger block and anti-fall block). It is fixed on the building with a spring washer and a single nut, and all the self-weight and load of the shelf are transmitted to the building. A general wall-attached sup...

Problems solved by technology

[0004] The anti-tilt, unloading and anti-drop stress points of general wall-attached supports are all concentrated on one point, which is likely to cause excessive local stress; therefore, during construction, the distance between wall-attached supports is not easy to set If it is too large, it needs to be set closely, provide more support points, prevent insufficient support force or anti-fall setting points, and have low safety, so the operation will easily increase the construction cost and reduce the construction efficiency
