Rake type lifting frame and dismantling method for reinforced concrete groove-shaped roof boards

Abstract

The invention discloses a rake type lifting frame and a dismantling method for reinforced concrete groove-shaped roof boards. The dismantling method for the reinforced concrete groove-shaped roof boards can conveniently dismantle the roof boards. The rake type lifting frame comprises two base supports, two inclined supports, two vertical supports and a plurality of horizontal supports; the two base supports which are horizontally arranged in a mutually parallel mode are arranged on external side at opposite two ends in the length direction of the roof boards to be dismantled; one ends of the two inclined supports and one ends of the two base supports are fixed; one ends of the two inclined supports upwardly extend obliquely in a mutually parallel mode; the length of the two vertical supports is identical; the two vertical supports are fixedly connected between the fixed base supports and inclined supports to support the inclined supports; the plurality of horizontal supports are connected between the two base supports and the two inclined supports; portions of the two inclined supports, which upwardly extend obliquely from connecting points of the vertical supports, are provided with two manual hoists which are used for lifting the roof boards; the horizontal distance between the two manual hoists which are arranged on the same inclined support is less than the width of the rood boards.

Description

technical field [0001] The invention relates to the field of roof panel removal construction, in particular to a rake-type hoisting frame and a method for removing reinforced concrete trough-shaped roof panels using the rake-type hoisting frame. Background technique [0002] At present, when removing reinforced concrete roof slabs, direct crushing or self-propelled cranes are mainly used for demolition. These two demolition methods need to stop production, and the production equipment of the roof accessories needs to be shut down, and these production equipment should be removed to avoid affecting the normal demolition or damage of the roof panels, making the roof panel removal process complicated and time-consuming longer. [0003] In some cases, due to the limitation of on-site construction conditions or workmanship, it may not be possible to set up large-scale truck cranes and tower cranes and other hoisting equipment, making it difficult to remove the roof panels.
