Description

Extremely frigid zones concrete frame electrical heating curing means
Technical field
This utility model is related to clear-water concrete maintenance technology field and in particular to one kind is suitable to extremely frigid zones winter construction Concrete frame electrical heating curing means.
Background technology
In the area such as NORTHWEST CHINA inland construction concrete, winter temperature is low, and winter time is long, there is the longer teletostage Engineering time.Because latitude is high, winter has considerable time to be in less than -15 DEG C, and extreme weather temperature can reach -29 DEG C, And -15 DEG C is the current limiting temperature commonly using concrete antifreezer on the market, it is accomplished by taking when ambient temperature is less than -15 DEG C Corresponding measure, in order to avoid concrete is endured cold.The structures such as main building, side coal bunker are subject to height, span and construction technology restriction it is impossible to adopt Under conventional low temperature environment, the mode of erection construction brooder is constructed.
Concrete curing under Conventional cryogenic mainly has a following arrangement and method for construction:
Under Conventional cryogenic, concrete curing is mainly using brooder method, and the program has the disadvantage in that 1. due to must in brooder Must need to drain into cigarette, burning gases outside canopy in time using this scheme, if discharge not in time will be to people using the heating of multiple stage stove Body causes safely uncertain injury, poor safety performance, is unfavorable for green construction;2. brooder method is mainly used in underground coagulation Soil structure or the position of concrete concentration, the scope of application is little, is unfavorable for towering, long span building thing maintenance;3. brooder method is applied Work occupied ground is big, and construction is loaded down with trivial details, complicated, and construction cost is high, and is unfavorable for site safety civilized construction;4. brooder method is mainly fitted For more than -15 DEG C of area, and the extremely frigid zones winter construction temperature such as northwest is up to -29 DEG C, and brooder method is unfavorable for concrete Freeze proof maintenance work.
Due to disadvantage mentioned above, brooder method is unsuitable for extremely frigid zones and can not meet towering, long span building thing concrete Maintenance work.
Utility model content
Technical problem to be solved in the utility model is to provide one kind safe and reliable and be applied to extremely frigid zones clear water to mix The extremely frigid zones concrete frame electrical heating curing means of solidifying soil maintenance.
For solving above-mentioned technical problem, the technical solution of the utility model is:
Extremely frigid zones concrete frame electrical heating curing means, including power supply and the described power supply break-make of control Master control switchs, and also includes the pre- some electrical heating elements being embedded in and being connected in concrete frame post beam and with described power supply, Some described electrical heating elements are connected in parallel with each other by wire;Each described electrical heating elements has been arranged in series temperature control respectively Device processed and earth leakage protective device, described temperature controller is connected with temperature indicator by wire.
As preferred technical scheme, described electrical heating elements are electrical heating wire.
As preferred technical scheme, described electrical heating wire is evenly arranged in concrete frame trestle beam and and framework of steel reinforcement Tight colligation is together.
Due to employing technique scheme, this utility model has the advantages that
First, expense is low, and whole system materials demand amount is few, high working efficiency, and other materials is equal in addition to electrical heating wire Reusable, improve the utilization rate of product, it is to avoid cause to waste;
Secondly, easy and simple to handle, regular reinforcement work just can complete to lay work to electrical heating wire, saves staff training Put into;
Again, temperature controllability is good, according to ambient temperature, just can be completed to concrete temperature by temperature controller Regulation control, quick heating, accelerate the growth of early age strength of concrete;
In addition, environmental protection performance is high, thermal source derives from electric power, it is to avoid the harmful, discharge of pollution gas.
Brief description
The following drawings is only intended to, in this utility model is done with schematic illustration and explanation, not limit model of the present utility model Enclose.Wherein:
Fig. 1 is the arrangement schematic diagram of this utility model embodiment;
Fig. 2 is the circuit theory diagrams of this utility model embodiment.
In figure: 1- power supply;2- master control switchs;3- frame column beam;4- electrical heating elements;5- temperature controller;6- leaks Non-electricity protector;7- temperature indicator.
Specific embodiment
With reference to the accompanying drawings and examples, this utility model is expanded on further.In the following detailed description, only pass through to say Bright mode describes some one exemplary embodiment of the present utility model.Undoubtedly, those of ordinary skill in the art is permissible Recognize, in the case of without departing from spirit and scope of the present utility model, can by with various different in the way of to described Embodiment is modified.Therefore, accompanying drawing and description are inherently illustrative, rather than for limiting the protection of claim Scope.
As depicted in figs. 1 and 2, extremely frigid zones concrete frame electrical heating curing means, including 220v power supply 1 and control Make the master control switch 2 of described power supply 1 break-make, also include pre- being embedded in concrete frame post beam 3 and electric with described power supply Some electrical heating elements 4 that source 1 connects, it can adopt electrical heating wire, and some described electrical heating elements 4 pass through wire mutually simultaneously Connection connects;Each described electrical heating elements has been arranged in series temperature controller 5 (as variable resistance box) and earth leakage protective device respectively 6, described temperature controller 6 is connected with temperature indicator 7 by wire, is realized to electricity by adjusting resistance value in galvanization The control of heater strip temperature, thus be adjusted to the temperature of concrete in real time;By temperature indicator real-time monitoring concrete Temperature.
In order to improve heats and being heated evenly property of concrete, and easy construction, described electrical heating wire is evenly arranged in In concrete frame trestle beam 3 and together with colligation tight with framework of steel reinforcement.
This utility model is directed to large span, the feature of tall and slender structure, the pre-buried electrical heating elements in concrete construction, and sets Put temperature controller, temperature indicator, after concrete construction is complete, electrical heating elements are energized and heat up, rely on electrical heating elements release Heat supplement concrete loss heat, slow down concrete cooling speed, by adjust temperature controller show concrete temperature, with Shi Peihe admixture early strength agent, antifreeze simultaneously coordinate the facilities such as external insulation, make concrete temperature be reduced to -15 DEG C of concrete before Intensity meets or exceeds concrete antifreezing critical intensity, to avoid freeze injury of concrete with this, simple to operate, connection and reasonable arrangement, safety Reliability, quick heating, temperature can easily be accommodated, and solve extremely frigid zones large span, the technology of high-rise structures clear-water concrete maintenance A difficult problem.
