Abstract

The invention discloses a high-air-tightness UHPC segmental beam steam curing chamber. The chamber comprises a steam curing pedestal, a curing chamber body frame, an air-tightness protection structure, a steam curing mechanism and a heating and cooling control mechanism. The curing chamber body frame comprises a profile steel frame and a movable top cover which are arranged at the top of the steam curing pedestal; and the profile steel frame is composed of square steel and I-shaped steel. The invention relates to the technical field of ultra-high performance concrete steam curing. According to the high-air-tightness UHPC segmental beam steam curing chamber, the movable contact parts of heat preservation panels, a top cover and side walls of the curing chamber are specially designed, the air tightness of the curing chamber is guaranteed, and therefore the steam curing temperature is guaranteed, heat loss is reduced, and energy is saved; and the problems that a large-size high-temperature steam curing chamber is poor in air tightness, uneven in temperature, difficult to control the heating and cooling rate and the like can be solved, the steam curing quality is improved, and the steam curing construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ultra-high performance concrete steam curing, in particular to a highly airtight UHPC segmental beam steam curing room. Background technique [0002] UHPC is mainly composed of cement, silica fume, fly ash, water reducer, quartz sand, steel fiber and other materials; it is constructed according to the principle of maximum compactness, and the pores between material particles are filled with materials with smaller particle sizes, so that The pores and micro-cracks inside the material are minimized; it has ultra-high strength and excellent durability due to its high density. The dispersed steel fibers in UHPC can greatly slow down the expansion of micro-cracks inside the material, so that UHPC has ultra-high toughness. [0003] Coarse aggregate is not added to UHPC, and the cement used has a high grade of strength and a large amount, resulting in large shrinkage. In order to improve the strength and densi...
