Embodiment 1

[0020] Embodiment 1: a kind of production technology of PC member, comprises the following steps,

[0021] A. Concrete production. The raw materials for concrete production include coarse aggregate, fine aggregate additive and cement. The mass percentage of each component is 10% of coarse aggregate, 70% of fine aggregate, 10% of additive, and 10% of cement. Put the coarse aggregate, fine aggregate additive and cement into the mixer, add water and mix to make concrete,

[0022] Aggregate mixing includes coarse aggregate mixing, fine aggregate mixing and various aggregate mixing. The speed of the low-speed operation of the mixer is 60-120 rpm, and the speed of the high-speed operation of the mixer is 240-540 rpm.

[0023] Coarse aggregates include crushed stones and pebbles, and the mass percentages of crushed stones and pebbles are 3% crushed stones and 7% pebbles. Coarse aggregate mixing includes putting crushed stones and pebbles into the same mixer according to the mass rat...

Embodiment 2

[0033] Embodiment 2: a kind of production technology of PC member, comprises the following steps,

[0034] A. Concrete production. The raw materials for concrete production include coarse aggregate, fine aggregate additive and cement. The mass percentage of each component is 8% coarse aggregate, 62% fine aggregate, 10% additive, and 20% cement. Put the coarse aggregate, fine aggregate additive and cement into the mixer, add water and mix to make concrete,

Abstract

The invention discloses a production process for a PC component. The production method comprises the following steps: manufacturing concrete from the following raw materials in percentages by mass: 5%-15% of coarse aggregate, 65%-75% of fine aggregate, 5%-15% of an additive and 10%-20% of cement, i.e., adding the coarse aggregate, the fine aggregate additive and the cement into a stirrer, adding water, and carrying out stirring so as to prepare the concrete; cleaning a mold, carrying out assembling, then moving the mold onto a production line, putting a prefabricated part into the mold so as to complete preparation of the mold; pouring prepared concrete into the mold, flatly laying the concrete, and carrying out vibration on the concrete so as to prepare the PC component; and dissembling the mold so as to complete manufacturing of the PC component. According to the invention, the structure is reasonable; and by adjustment of the mass ratio of the raw materials, the PC component with characteristics of low density, high hardness and good curing effect can be prepared.

Description

technical field [0001] The invention relates to the field of manufacturing PC components, in particular to a production process of PC components. Background technique [0002] PC is the English abbreviation of prefabricated concrete, which is called PC component in the field of housing industrialization. Such as prefabricated reinforced concrete column foundation, prefabricated steel structure steel column foundation, street lamp billboard column reinforced concrete foundation, prefabricated floor slab. Correspondingly, traditional cast-in-place concrete requires on-site molding, on-site pouring and on-site maintenance. Prefabricated concrete is widely used in construction, transportation, water conservancy and other fields, and plays an important role in the national economy. [0003] In the production of PC components, in order to strengthen their strength, the density of PC components is often increased, resulting in high quality PC components, difficult handling, and g...
