Abstract
The invention provides a concrete steam curing kiln technology for an intelligent housing and belongs to the field of buildings. The steam curing technology of concrete comprises four phases, namely a precuring period, a temperature raising period, a constant temperature period and a temperature reducing period; the whole procedure is intelligently controlled by adopting computer program; data measured by a temperature sensor are transmitted to a computer and a PLC (Programmable Logic Controller) through a data signal cable; a computer controls switches of all valves in the steam curing kiln by the PLC according to the precompiled program, so the temperature is controlled; the steam curing procedures are finished through the precuring period, the temperature raising period, the constant temperature period and the temperature reducing period in sequence. According to the technology, the problem that the construction in winter is influenced by air temperature is solved, shrinkage cracks are avoided and the quality of members is improved; in addition, the production period is shortened, and the production efficiency is greatly improved.
Description
Technical field
The present invention relates to the concrete steam-cured kiln technology of a kind of intelligent house, belong to building field.
Background technology
Concrete in intelligence house needs to carry out steam-cured, so not only solves the problem that winter construction affects by temperature, avoids shrinkage crack, raising component quality, and shortens the production cycle, substantially increases production efficiency.
Concrete steam-cured excitation utilizes the wet effect conduction of the heat of steam to concrete, thus the hardening process of accelerate concrete, make it to reach design strength as early as possible.Concrete will carry out hot and humid area with damp-heat air in steam-cured process, concrete generation series of physical change in the process.The concrete of newly building has aggregate, cement paste, water and air to steep four kinds of compositions, and their main generation heat expansion effects in steam-cured process occur in inner " crack ", thus concrete strength is reduced.Concrete is through steam-cured, and stop input steam to lower the temperature, in the process, particularly during winter, concrete will shrink and easily occur scaling and crack.Therefore, rational technical scheme need be taked in steam-cured process.
Summary of the invention
This concrete steam-cured system includes heating system, temperature control system, aeration cooling system and curing cover system.Wherein temperature automatic control is steam-cured important step.
This concrete steam-cured technology is divided into four-stage: precuring phase, temperature raising period, constant temperature phase, cooldown period.Whole program adopts computer program Based Intelligent Control.The data of temperature sensor measurement are sent to computer and PLC by data signal line, computer is according to program (heating up time set and speed, constant temperature time and speed, temperature fall time and speed etc.) prepared in advance, to control in steaming kiln each valve switch with control temperature by PLC, thus complete steam curing process.
Accompanying drawing explanation
Fig. 1 is concrete steam-cured each stage temperature control figure in the present invention.
Detailed description of the invention
Below coordinate Figure of description and do more detailed description in conjunction with example to kiln technology concrete steam-cured in the present invention, operating process is shown in accompanying drawing 1.Concrete operation step is:
Concrete steam-cured technology is divided into four-stage: precuring phase, temperature raising period, constant temperature phase, cooldown period.Whole program adopts computer program Based Intelligent Control.The data of temperature sensor measurement are sent to computer and PLC by data signal line, and computer, according to program prepared in advance, to control in steaming kiln each valve switch with control temperature by PLC, thus completes steam curing process.
Time precuring phase is 3-6h, and temperature is 30 DEG C.
Temperature raising period is, in 3h, temperature is risen to 60 DEG C by 30 DEG C, control programming rate.Within 1st hour, be warming up to 40 DEG C, within the 2nd hour, be warming up to 50 DEG C, within the 3rd hour, be warming up to 60 DEG C.
Constant temperature phase temperature controls at 60 DEG C, and the time is about 10h.
Cooldown period is, in 3h, temperature is down to 30 DEG C by 60 DEG C, control cooling rate.Should ensure to reduce cooldown period to the damage of concrete structure, shorten curing period again as far as possible.
