Novel precast concrete pipe die and construction method thereof

Abstract

The invention discloses a novel precast concrete pipe die, which is a precast concrete pipe pile of a hollow structure. The wall of the precast concrete pipe die is internally provided with annular and vertical reinforcing steel bars, the inner surface of the pipe die is provided with dowel bars connected with post-poured concrete into a whole and an electric heating wire for heating, the upper end and the lower end of the pipe die are provided with tooth-shaped connectors which are mutually matched, the wall of the pipe die is internally provided with preset pore canals for prestress reinforcing steel bars, and the pore canals are through longitudinally. A construction method of the novel precast concrete pipe die comprises the steps of: after positioning the precast concrete pipe die, switching on a power supply of the electric heating wire, and performing high-dropping self-compacting concrete pouring on the middle of the concrete pipe die; and after a first section of cylinder core of the pipe die is poured, performing hoisting positioning and concrete pouring on a second section of the concrete pipe die. The invention has the advantages that by precasting the concrete pipe die, the special requirement on the use functions of a concrete column surface and a column template can be met, and the heating functions of the novel precast pipe die can also ensure the smooth construction in winter; and the novel precast concrete pipe die and the construction method thereof have the advantages of simplicity and rapidness for construction, less required construction equipment, and capability of greatly reducing the construction cost and the comprehensive manufacturing cost.

Description

technical field [0001] The invention relates to the structure of concrete columns in construction engineering and its construction technology, in particular to a novel prefabricated concrete pipe form and its construction method. Background technique [0002] At present, in the field construction of concrete column structures in construction projects, quality problems often occur due to the control of formwork construction accuracy. In addition, for some concrete column surfaces with special requirements, such as fair-faced concrete surfaces, the cost of erecting formwork is high. Quality is not easy to guarantee. Contents of the invention [0003] The object of the present invention is to address the above existing problems and provide a new type of precast concrete pipe form and its construction method. The structural precast concrete pipe form can be used as a structural template, the construction is simple and convenient, and the construction cost of the column structu...
