Pull-rod-free construction formwork for slab culvert wall body

Abstract

The invention belongs to the field of building construction, and particularly relates to a slab culvert wall body pull-rod-free construction formwork which comprises an inner formwork and outer formworks, the inner formwork and the outer formworks are vertically arranged in parallel, outer supporting frames are arranged on the sides, away from each other, of the outer formworks, gravel layers are arranged on the lower sides of the outer formworks, and the outer supporting frames are arranged on the lower sides of the outer formworks. A base layer is arranged on the lower sides of the inner formworks, supporting blocks are fixedly connected to the middles of the sides, close to each other, of the inner formworks, and each supporting block is of an isosceles trapezoid structure. The inner formwork and the outer formwork do not need to be supported and fixed through a pull rod, the supporting effect of the inner formwork and the outer formwork can be effectively guaranteed, and therefore the problem of roadbed damage caused by water leakage of a pull rod hole due to use of the pull rod is solved, and the appearance quality of concrete is improved; and furthermore, disassembly and assembly are convenient, disassembly, assembly and transportation are convenient, repeated use can be achieved, practicability is high, and application and popularization are convenient.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a tie-bar-less construction formwork for a cover plate culvert body. Background technique [0002] Cover plate culvert refers to a culvert in the form of an integral or separate foundation and a culvert body, and the cover plate and the culvert body are hinged, generally used as a water-passing culvert or a pedestrian crossing. Cover plate culvert cut-and-cover operation is suitable for geology with low groundwater level and less permeable foundation and pit wall after foundation pit excavation. The bearing capacity of the original base or the base after management meets the design requirements, and there are certain construction site and material transportation conditions. [0003] The main contents of cover plate culvert construction include: foundation pit excavation, foundation and culvert construction, steel bar processing and installation, cover p...

AI Technical Summary

Problems solved by technology

After dismantling, tie rod eyes will be left on the culvert body. After these tie rod eyes are put into use, water will leak, which will cause roadbed diseases; at the same time, it will seriously affect the appearance quality of concrete
