H-shaped supporting pile die with steam curing device

Abstract

The invention discloses an H-shaped supporting pile die with a steam curing device. The H-shaped supporting pile die comprises at least one die unit, wherein each die unit comprises a bottom plate, a left side plate and a right side plate which are hinged with the bottom plate, and a hollow part is formed by the left side plate, the right side plate, a left cavity panel and a right cavity panel. The H-shaped supporting pile die further comprises an oil cylinder connected with the left side plate and the right side plate, and a base used for fixing the oil cylinder, wherein the bottom end of the oil cylinder is hinged with the base, and a plurality of support structures used for preventing the left cavity panel and the right cavity panel from deformation are arranged in the hollow part; steam channels used for steam flowing are arranged on the support structures; the die unit is connected with a steam source by a pipeline, and the hollow part is communicated with the pipeline. The H-shaped supporting pile die disclosed by the invention has the advantages of fast heat production during steam curing, short curing time, high production efficiency and steam cyclic utilization.

Description

technical field [0001] The invention relates to the technical field of concrete piles, in particular to an H-shaped support pile mold with a steam curing device. Background technique [0002] At present, reinforced concrete round piles are mostly used in foundation pit maintenance projects and slope stabilization projects. Since it is a round pile, the direction of the contact surface between it and the surrounding of the foundation pit is different, and only a single point in one direction plays a supporting role in the process of being squeezed by the foundation pit, so that each steel bar in the reinforced concrete round pile There is only one direction of force, which is easy to cause uneven force, low bending resistance and shear resistance; in addition, reinforced concrete round piles also have disadvantages such as high cost, slow construction speed, and environmental pollution from construction mud; in order to solve the above technical problems, The applicant propo...

AI Technical Summary

Problems solved by technology

For the above-mentioned existing traditional molds, after the H-shaped support piles are prepared, the mold and the support piles need to be steam-cured as a whole; in this traditional curing method, the steam needs to be heated from the outside of the mold to the H-shaped support piles. For maintenance, the steam must pass through a thick mold before it can transfer heat to the support pile for maintenance, resulting in poor heat transfer effect and long maintenance time (generally more than 41 hours), the H-type support pile per unit time The production quantity is small and the production efficiency is low; in addition, the steam in this traditional curing method cannot be recycled, resulting in low steam utilization rate and high energy consumption

[0004] Moreover, for the above-mentioned traditional mold, when a plurality of mold units are arranged along the length direction to prepare a plurality of H-shaped support piles at the same time, the solidification and forming process of the support piles will be caused by the external environment (such as temperature difference between morning and evening, steam curing, etc.) The change of thermal expansion and contraction requires a certain spatial displacement, but since each mold unit is rigidly connected, the displacement space is small, which will cause distortion and deformation of the mold and H-shaped support piles, seriously affecting the quality of the final product stability
