Embodiment

As shown in figure 1, the thermal insulation casing component with outer protection tube includes central tube 11, heat-insulation layer 12, outer protection tube 13, wherein protecting Warm layer 12 is covered on the outer surface of central tube 11, and outer protection tube 13 is enclosed on the outer surface of heat-insulation layer 12, and the entirety of heat-insulation layer 12 is In length range in outer protection tube 13.I.e. the length of heat-insulation layer 12 is less than or equal to the length of outer protection tube pipe 13, outer protection tube 13 Length be less than central tube 11 length.Length and so that heat-insulation layer of the length of preferable outer protection tube 13 slightly larger than heat-insulation layer 11 Inside of 11 both ends all in the both ends of outer protection tube 13.The both ends of central tube 11 are exposed independent from outside the both ends of outer protection tube 13.The center Metal tube (such as steel pipe, iron pipe, stainless steel tube, compo pipe), plastic tube can be selected in pipe 11 and outer protection tube 13, heat-insulation layer 12 Material can be polyurethane foam material etc..

The main structure of the thermal insulation casing component with outer protection tube is that heat-insulation layer 12 does not cover central tube 11 above It is elongated, but only cover the part in the length of central tube 11, whole length of the covering and heat insulating layer 12 of outer protection tube 13, outer protection tube 13 both ends are concordant with the both ends of heat-insulation layer 12 or the both ends of slightly longer than described heat-insulation layer 12, to provide to heat-insulation layer 12 Good protection, central tube both ends respectively have one section to expose heat-insulation layer 12 and outer protection tube 13.This structure, both avoids waste of materials, Easily it can be connected simultaneously after the installation through walls of thermal insulation casing component with other pipe fittings.

Fig. 2 shows a kind of structure through walls using the thermal insulation casing component with outer protection tube, as shown in Fig. 2 in masonry wall Wall bushing 24 is reserved during body 31, the wall bushing can be metal tube (such as steel pipe, iron pipe, stainless steel tube, compo pipe) Or plastic tube, the body outer ring of wall bushing 24 is provided with wing ring 32, and in masonry panel 31, wing ring 32 is embedded in wall 31, with along axle To the fixation wall bushing.Wall bushing 24 (i.e. indoor and outside) inside and outside wall is provided with along wall to turn up Side 27, the flanging of indoor have certain thickness, are evenly distributed with multiple screwed holes thereon；The body inner ring of wall bushing 24 The undertaking ring 26 being interval with more than two circles.

When thermal insulation casing component with pillar is installed, first the thermal insulation casing component is passed from wall bushing 24, Outer protection tube 24 installs (carrying) on ring 26 is accepted inside wall bushing 24, and side and outside, which are exposed independent from one section, indoors includes The part of heat-insulation layer 22, outer protection tube 24.The effect that ring 26 also acts as back-up ring is accepted, elastic seal ring 25 is enclosed on by side indoors In outer protection tube 23, and it is pushed into wall and is contacted until with accepting ring 26, is afterwards enclosed on flange gland 28 from indoor side direction outer Pushed against on pillar 24 and by flange gland boss to sealing ring 25, bolt 29 is existed through the through hole on ring flange with wall bushing Screwed hole on the flanging of indoor screws, and is accepted so that sealing ring 25 is fastened on 26 on ring, after deforming it Play a part of sealing, thus can realize the sealing between outer protection tube 23 and wall bushing 24, avoid the corrosive liquid of indoor Body intrusion is polluted and corroded.

In outside, flexible pointing, such as spunyarn, modified pitch are inserted between wall bushing 24 and outer protection tube 23 Deng, and the flexible pointing is filled to the undertaking ring of outside, sealing compound 33 is filled on the outside of flexible pointing, Such as polyurethane paste for sealing in building, polysulfide rubber sealing compound, and make it that the sealing surface of sealing compound 33 and outside flanging 27 are flat Together, by above-mentioned outdoor sealing structure, good sealing effectiveness can be played.

By the utility model, the prefabricated of thermal insulation casing component can be realized, realizes that wall pipe is uninterrupted within the walls Insulation, for the utility model in installing construction, mounting process is simple, easy for construction, reduces cost, improves construction matter Amount.
