Hidden pre-embedded hoisting device and construction method thereof

Abstract

The invention discloses a hidden pre-embedded hoisting device and a construction method thereof. The hidden pre-embedded hoisting device comprises a pre-embedded clamp, anchoring hooks, a lifting ringscrew and a sealing film, wherein the pre-embedded clamp is embedded in building roof concrete, a threaded hole is formed in the bottom of the pre-embedded clamp, an opening of the threaded hole is temporarily blocked through the sealing film, and the anchoring hooks are fixedly arranged on the pre-embedded clamp; and the anchoring hooks are anchored on building structural steel bars. Before a bottom template of the building top plate is closed, the bottom surface of the pre-embedded clamp exceeds the elevation of the bottom surface of the building top plate; after the bottom template of thebuilding top plate is assembled, the bottom surface of the pre-embedded clamp is tightly propped against the bottom template of the building top plate under the elastic action of the anchoring hooks;and after the bottom template of the building top plate is demolded and the sealing film is torn off, the bottom surface of the pre-embedded clamp is flush with the bottom surface of the building topplate, and the lifting ring bolt is mounted in a threaded hole in the bottom of the pre-embedded clamp in a threaded manner. Materials are easy to obtain, the structure is simple, manufacturing is convenient, hole reservation can be completed accurately without errors without cutting a template, and waste of manpower and material resources is avoided.

Description

technical field [0001] The invention relates to the technical field of reserved pre-embedding of the roof of a main body of a building structure, in particular to a hidden pre-embedded hoisting device and a construction method thereof. Background technique [0002] At present, in building construction projects and house decoration projects, in order to hoist equipment, install lamps, etc., it is necessary to cut the formwork to reserve holes. Increase the difficulty of its assembly, reduce its service life, reduce its turnover times, and even grout leakage occurs during concrete pouring, which not only has potential safety hazards, but also cannot accurately complete the hole reservation, resulting in a waste of manpower and material resources. Contents of the invention [0003] The purpose of the present invention is to propose a hidden pre-embedded hoisting device and its construction method to solve the above-mentioned technical problems in the background technology cau...
