Waterproof, antiseptic property be good, investment reduction, shortens the plurality of advantages such as construction period, maintenance cost be low.And it is used at present prefabricated straight
Pipe laying is made of steel pipe, erosion resistant coating, holder, five part of protective layer, is the utilidor of monoblock type, because of steel pipe in heat supplying process
The temperature of interior hot water or steam is very high, steel pipe certainty expanded by heating, and the coefficient of expansion of steel pipe, three kinds of insulating layer, holder substances
Difference will be unable to synchronous shift between this three, will cause to generate certain cracking phenomena between insulating layer, steel pipe, holder,
I.e. between insulating layer and steel pipe, between insulating layer and holder, certain gap, this gap meat are generated between holder and steel pipe
Eye may not observe, but heat-energy losses caused by by gas heat transfer in gap are inestimable.
Utility model content
It is above-mentioned to solve the purpose of this utility model is to provide a kind of prefabricated direct-buried thermal insulation pipe preventing cold bridge heat loss
Between the insulating layer and steel pipe that are proposed in background technology, between insulating layer and holder, between being generated centainly between holder and steel pipe
Gap, this gap may with the naked eye not observe, but heat-energy losses caused by by gas heat transfer in gap can not
The problem of appraisal.
To achieve the above object, the utility model provides the following technical solutions：It is a kind of to prevent the prefabricated straight of cold bridge heat loss
Insulating tube, including transmission tube body are buried, the transmission tube body includes interior transmission steel pipe, external thermal insulation pipe and heating column, the heating column
It is uniformly connected on the outer wall of interior transmission steel pipe, the external thermal insulation pipe is coated on the outer wall of interior transmission steel pipe, the external thermal insulation
Straight slot compatible with heating column is uniformly provided on pipe, the left and right ends of the transmission tube body are welded with connecting flange, institute
It states connecting flange to be welded on the outer wall of interior transmission steel pipe, supporting sleeve is socketed in the middle part of the outer wall of the transmission tube body, it is described
The inner wall of supporting sleeve is equidistant to be equipped with four groups of supporting pads, and the supporting pad is supported on the outer wall of transmission tube body.
Preferably, polytetrafluorethylecoatings coatings are uniformly coated on the inner wall of the interior transmission steel pipe.
Preferably, the heating column is steel heating column.
Preferably, the external thermal insulation pipe is PVC insulating tubes.
Preferably, the supporting sleeve designs for open type, and the open end of supporting sleeve is connected by screw.
Compared with prior art, the utility model has the beneficial effects that：This programme is by by interior transmission steel pipe and external thermal insulation
The temperature difference between pipe is disperseed even heat by the transmission mode of heating column, the phenomenon for causing temperature difference excessive is avoided, to pipe
Road plays the role of protection, increases service life.
