Constructional column dustpan mouth chiseling prevention apparatus

Abstract

The present invention discloses a constructional column dustpan mouth chiseling prevention apparatus, comprising a constructional column template, dustpan mouths, a closing apparatus and guide apparatuses. The dustpan mouths are fixedly disposed on both sides of a casting port; the guide apparatuses are separately arranged on both sides of the casting port and fixedly connected to the constructional column template; the closing apparatus is slidably connected to the constructional column template by means of the guide apparatuses; when the closing device slides to different positions, the casting port is in a closed or open state; an assistance apparatus is fixedly provided on the constructional column template; and an output end of the assistance apparatus is fixedly connected to the closing apparatus. By providing the assistance apparatus for pushing a closing baffle plate on the constructional column template, the automatic insertion of the closing baffle plate is implemented, so that the manual pushing of the baffle plate is saved, both time and power are saved, and the safety is improved; and by providing a sealing strip between a fixed lug plate and the constructional columntemplate and leakage prevention strips at the lower ends of the dustpan mouths, the airtightness of the apparatus is improved, the dust leakage phenomenon in the casting process is effectively prevented, and building materials are saved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a chisel-free device for a dustpan mouth of a construction column. Background technique [0002] In the field of construction engineering technology, for building masonry construction, the construction of structural column concrete pouring is commonly used. The process adopts wooden beams and wood plywood to support the structural column pouring formwork, and a gap for pouring concrete is provided on the top of the pouring formwork. The concrete is poured and hardens to form the structural columns. [0003] In actual concrete pouring, in order to facilitate pouring and improve pouring efficiency, it is usually necessary to set a dustpan mouth at the concrete pouring gap on the top of the formwork. The gap of the hole falls into the formwork, and after the concrete is hardened, the formwork and the dustpan mouth are removed, and then the concrete filled in the dustp...

AI Technical Summary

Problems solved by technology

At present, there have been chisel-free structural column dustpan opening devices, including dustpan openings, baffles, guide grooves and other structures, but there are still deficiencies: (1) After the pouring is completed, the baffles need to be manually pushed, because the baffles are generally The labor intensity and potential safety hazards of construction personnel are increased at high places, which is a relatively large safety hazard point; (2) During the pouring process, due to poor sealing between the dustpan mouth and the formwork, concrete leakage often occurs, which not only affects The quality of construction can also cause waste of materials
