Abstract
The utility model provides a concrete heater for winter construction. An asbestos heat insulation layer, a reinforced concrete layer and a heat transfer layer are sequentially formed at the bottom of the heater from bottom to top, wherein a groove for paving heat supply pipelines is reserved in the reinforced concrete layer, fine sand materials are piled on the heat transfer layer, the top part and the periphery of the fine sand materials are covered with the sealed heat insulation layer. The concrete heater solves the problems of difficult assurance and low construction efficiency of winter concrete construction, and ensures the scheduled and high-quality construction completion of the winter concrete construction.
Description
Technical field
The utility model belongs to the concrete construction technology field, is specifically related to a kind of teletostage concrete construction device that is used for.
Background technology
When environment round the clock temperature on average be lower than for three days on end and enter winter construction when 5 ℃ or the lowest temperature are lower than-3 ℃.Teletostage concrete characteristics are: prolong 3 times than 15 ℃ time of setting in the time of 0～4 ℃, and concrete begins to freeze when temperature is reduced to-3～-5 ℃, and hydration reaction stops fully when reducing to-10 ℃, and concrete strength no longer increases.Water freezing under the subzero temperature condition in the concrete, volume increase make the concrete structure of sclerosis suffer frost heaving failure.
Therefore the teletostage concrete construction has shortcomings such as quality risk is big, construction cost input height, construction production efficiency is low, the engineering safety accident takes place frequently.Be to guarantee concrete winter construction quality, construction period concrete crushing strength do not reach design strength 30% before must not endure cold, concrete crushing strength must not endured cold before reaching 5MPa yet.And the present relevant report that teletostage concrete construction temperature control device is not arranged as yet.
Summary of the invention
The purpose of this utility model is to provide a kind of concrete heater that is used for winter construction, has solved the problem that teletostage concrete construction efficient is low, quality risk is big.
The utility model is achieved through the following technical solutions:
Concrete heater bottom from bottom to top is followed successively by insulating layer of asbestos, reinforced concrete floor and heat transfer layer, leaves the groove of laying heating line in the reinforced concrete floor; Stack the fine sand material on the heat transfer layer, cover sealed insulating layer around fine sand material top reaches.
Through repetition test repeatedly, the steel concrete layer thickness is best with 15cm, and groove pitch adopts 60cm, ditch groove width 6cm, and the employing seamless steel pipe is a heating line, as the thick 8mm of steel plate of heat transfer layer.
In order to guarantee to add thermal effect and reduce production costs as far as possible, adopting common thick cotton felt is sealed insulating layer; In order to guarantee to add thermal effect and easy construction, the fine sand thickness of feed layer is advisable not to be higher than 3m in the heater.
Advantage of the present utility model is:
Adopt concrete heater of the present utility model to guarantee that at low temperatures concrete is about 10 ℃, prevent under the subzero temperature condition owing to water freezing in the concrete makes the concrete structure of sclerosis suffer frost heaving failure, efficiently solve the problem that the teletostage concrete construction quality has a big risk, improved production efficiency simultaneously, won the quality time for guaranteeing the duration.

The specific embodiment
Below be preferred embodiment of the present utility model, the utility model can the described content of by specification elect any mode to implement.
Specify below in conjunction with accompanying drawing:
See accompanying drawing 1, repave insulating layer of asbestos (1) after in existing construction plant, cleaning out, the cast thick steel concrete of 15cm (2) on insulating layer of asbestos.Stay the groove (3) of 15 * 6cm in the concrete by spacing 60cm, be used to and lay seamless steel pipe heating line (4).Lay the thick steel plate of 8mm above the concrete as heat transfer layer (5), also as the track of loader; Stacking is not higher than the fines of 3m on it, the whole angle steel that adopts of device is set up, and height need satisfy the requirement of charging car discharging high safety, uses thick cotton felt (6) to go along with sb. to guard him insulation all around, with thick cotton felt movable door curtain (7) is set at charging aperture, in time closes door curtain after the charging car is gone out.Above concrete heater adopts the steam heating boiler heating, connects heating line (4) and steam valve from the boiler room.
The fines that transhipment just comes is expressed board and is indicated it is the preheating zone, in time covers after fines piles with; Open big steam valve heating, and indicate it is the thermal treatment zone; Can stop to heat up when sand material temperature reaches 10 ℃, suitably turn down steam valve, in time indicate it is heat preservation zone.The fines of heat preservation zone is adopted in the concrete configuration, and finishing using in time covers tarpaulin tightly, and steam insulation is to treat building use next time.Measure the fines temperature with energy efficient every two hours, measure fines temperature and moisture content before using.
Use in order to guarantee that heating line (4) is normal, yard piping is from inside outwards respectively rolled up one deck with asbestos, sponge, cloth, and when not heat supply Guan Lishui is drained only.
Claims (7)
