Vertical integral forming mould of novel prefabricated concrete segment and forming method thereof

Abstract

The invention discloses a vertical integral forming mould of a novel prefabricated concrete segment and a forming method thereof, and the forming mould is assembled by an inside template, an outside template, a partitioning board, a bottom die, a cover plate and a positioning spigot. The forming method comprises the following steps: firstly assembling the mould, positioning and fixing reinforcing bars in the segment to the mould, reserving pre-stressed ducts, casting high-intensity and self-compaction concrete, and finally installing the cover plate on the mould to form the prefabricated concrete segment with the special shape. In the forming mould and the forming method, prefabricated concrete segments with different shapes and sizes can be manufactured as needed and are accurate in size and simple in manufacturing method, thus the forming mould and the forming method are applied to industrialization quantity production.

Description

technical field [0001] The invention relates to a forming mold and a forming method of a prefabricated concrete product, in particular to a forming mold and a forming method of a prefabricated concrete segment, and belongs to the field of prefabricated assembly. Background technique [0002] As the name suggests, precast concrete segments are the application of concrete prefabrication technology in segments, and are used in urban sewers, sewage wells and other projects. With the development of urban underground rail transit, shield tunnel segments have become the main components of precast concrete segments. App direction. The use of prefabricated concrete segments has the following advantages: factory-like assembly line operation can reduce the possibility of environmental pollution and traffic jams during on-site construction, and give full play to the advantages of factory-like operation management; quality management is easier to control, and can effectively reduce the r...

Problems solved by technology

Obviously, although this method is relatively simple and requires little investment, it is subject to manual constraints.

[0009] The above-mentioned precast concrete segment forming molds have the following disadvantages: high-precision molds are expensive and are not suitable for popularization and application in small and medium-sized enterprises; Precast concrete segments are poured in blocks, and large errors are prone to occur when ringing; in order to meet the accuracy requirements, the molds are often very heavy and inconvenient to turn over; when using low-cost manual vibration molds, they are often affected by the vibration space and Effects on worker levels, etc.
