Concrete pouring process for large-angel sloping roof

Abstract

The invention discloses a concrete pouring process for a large-angel sloping roof, and belongs to the field of building construction. The concrete pouring process comprises the following steps: (1) laying bottom-layer wood formworks of the sloping roof; (2) fixing a plurality of guide rails to the bottom-layer wood formworks from the left ends to the right ends in sequence, wherein the guide rails are arranged from the slope bottom to the slope top and respectively composed of two pieces of U-steel, and the openings of the two pieces of U-steel of each guide rail are opposite; (3) installing steel formworks in the guide rails composed of the U-steel, wherein vibrators are installed on the steel formworks respectively; (4) arranging lifting devices on the portions, above the guide rails, of the roof; (5) pouring concrete into the two pieces of U-steel of each guide rail and starting the vibrators at the same time; (6) after pouring the concrete, starting the lifting devices to drive the steel formworks to slide upwards; (7) after the steel formworks slide upwards, secondary grinding is carried out. By means of the concrete pouring process, the traditional double-layer wood formwork construction process is improved, the concrete is easy to feed, vibrating compaction and formwork thickness control are easy, the surface is flat and does not need to be leveled secondarily, and waste of wood is reduced.

Description

technical field [0001] The invention belongs to the field of building construction, in particular to a concrete construction process for a large-angle sloping roof. Background technique [0002] Existing concrete construction technologies for sloping roofs mostly use vibration and then compaction treatment or double-layer wooden formwork. Due to the limitation of the roof angle, the existing technology cannot be vibrated, the concrete is easy to slide and accumulate, the pouring time is long, and the flatness of the surface is not easy to control , Secondary roofing mortar or fine stone concrete leveling phenomenon, labor-intensive and material-intensive. Contents of the invention [0003] The purpose of the present invention is to provide a concrete pouring process for large-angle slope roofs with easy concrete blanking, convenient vibration and compaction, control of plate thickness, smooth surface and no need for secondary leveling. [0004] The technical scheme for re...
