Description
Technical field
The present invention relates to the technical field of winter building construction heating, particularly a kind of concreting in cold weather is electric adds
Thermal process.
Background technology
Engineering construction specification is provided：When continuous 5 days, daily mean temperature would fall to less than 5 DEG C, and engineering construction enters winter
Construction stage, engineering construction must be carried out according to the requirement of winter construction, and the construction such as build a wall, plaster must stop, and concrete is poured
Construction is built after taking measures, can be carried out.But concrete is during cryogenic temperature condensation, the hydration of cement is hindered
Hinder, influence concrete strength increases；Though concrete is endured cold initial stage, its intensity can increase, and later strength is but extremely difficult to design
It is required that.Under normal circumstances, winter construction uses hot water mixing often using no chlorine antifreezing agent is added in concrete, improves coagulation
The measures such as native label, overcome the reduction of concrete concrete actual strength caused by being cooled；Or after the completion of concreting, adopt
Take heating means, it is ensured that 5 ~ 8 days temperature of concrete continuous are more than 5 DEG C, and in practice of construction, particularly high-rise is applied
It is difficult to realize in work, conventional heating methods are to heat the space air where concrete, and heat waste is big, and heating effect is poor, and
And constructed with conventional heating methods, concrete at least improves a label than design.
The patent of Application No. 201310120315.5 discloses a kind of cold weather concrete heat tape auxiliary maintenance process,
Carry out as steps described below：（1）Support shuttering first, complete the reinforcement installation of site concrete, built-in fitting place welding job with
Afterwards, heat tape is laid in site concrete and is fixed on fixing band on reinforcing bar；（2）After detecting that heat tape is intact, pour
Concrete, in site concrete surface covering insulation material, after the completion of covering, is powered to heat tape, makes temperature to concrete heating
Degree maintains 5 ~ 8 DEG C.There are following defects in the method：1. heat tape is preset in site concrete, pour after concrete, no
It can take out, when the concrete to site concrete is heated, it is necessary to which substantial amounts of heat tape, cost is higher；2. in site concrete
Laying heat tape is simultaneously fixed on reinforcing bar, the more difficult laying of heat tape with fixing band, and electricity can be added during casting concrete
The position in the torrid zone produces influence；3. easily producing destruction during casting concrete to heat tape, it can not be repaiied after heat tape destruction
It is multiple, it is impossible to use；4. after detecting that heat tape is intact, heat tape is powered, and the time heated generally requires 5 ~ 8 days, by
It is fixed in heat tape by fixing band on reinforcing bar, heat tape can bring about greatly during heating once leaking electricity
Potential safety hazard.Here it is the weak point present in prior art.
The content of the invention
The technical problems to be solved by the invention, aiming at the deficiency present in prior art, and provide a kind of coagulation
Native winter construction electrical heating process, can meet the requirement to concrete temperature after building concrete is poured, and improve concrete
Intensity.
This programme is achieved by the following technical measures：A kind of concreting in cold weather electrical heating process, its feature
It is：Comprise the following steps：
（1）The reinforcing bar of colligation site concrete, support template presets plastic tube in site concrete and fixes plastic tube；
