Flue hoisting clamp

Abstract

The invention relates to a clamp and in particular relates to a flue hoisting clamp. The flue hoisting clamp comprises an extension pipe, a bracket plate connected at the bottom of the extension pipe and a flue frame connected at the top part of the extension pipe, wherein the flue frame is a square hollow straight tube which has a closed upper end and is larger than a flue, and a hook is arranged on the top surface of the outside of the straight tube; the extension pipe is composed of mutually-nested straight pipes, the length of the extension pipe in an extension state is equal to the length of the flue, the upper end of the straight pipe is arranged on the top surface of the inside of the flue frame, and an air bag is arranged between the straight tube and the extension pipe; the bracket plate is composed of two straight plates of which one ends are intersected, the intersected point of the straight plates is arranged at the bottom of the extension pipe by a locating pin, one end of the straight plate is provided with a baffle plate perpendicular to the upper end surface of the straight plate, and the lower end surface of the straight plate is provided with a spring for connecting the two straight plates. The flue hoisting clamp has the beneficial effects that when the flue is hoisted, the stressed area of the clamp and the flue wall is increased, and the flue outlet is prevented from collision.

Description

technical field [0001] The invention relates to a fixture, in particular to a flue hoisting fixture. Background technique [0002] The flue refers to the pipe products used to remove the smoke generated by the cooking activities in the kitchen or the dirty air in the bathroom. It is the main component of the exhaust pipe system shared by the residential kitchen and the bathroom. It is prefabricated by alkali glass fiber mesh cloth or ordinary portland cement with steel wire mesh and other reinforcing materials. When installing the flue, the traditional method is to tie the top of the flue with a pull rope and then hoist it, but there are The problem is: the flue wall is relatively thin, so it is directly tied with a pull rope, and the stress area acting on the flue wall is small, which easily damages the flue opening; Cause gas leakage at the flue connection. Contents of the invention [0003] The object of the present invention is to provide a flue hoisting fixture whic...
