Abstract
The utility model discloses a prefabricated polyurethane foam heat-preservation joint for a trench, which is used for connecting joints of two sections of prefabricated polyurethane foam heat-preservation pipes. Polyurethane foam tile blocks are coated at the joints of the two sections of prefabricated polyurethane foam heat-preservation pipes. Heat-shrinkable tapes are arranged outside the polyurethane foam tile blocks for tightening. The prefabricated polyurethane foam heat-preservation joint for the trench adopts polyurethane foam as a heat-preservation material so as to well improve the heat-preservation performance; and simultaneously, the joint has a simple structure, is simple and convenient to operate and has remarkable effects.
Description
Technical field
The utility model relates to a kind of insulation joint, relates in particular to a kind of trench with prefabricated polyurethane foam insulation joint.
Background technique
Trench carries out prefabricated in factory with prefabricated polyurethane foam insulation pipe, after on-the-spot steel pipe welding is finished, need the docking port place to carry out on-the-spot joint insulation.
This insulation operation is higher to technological requirement, and the production time of joint also affects the whole duration of project to a great extent.
At present the thermal insulating material that uses has rock wool, glass wool, perlite watt etc., the thermal conductivity height of these thermal insulating materials, and power consumption is big, complicated operation, and also the life-span is short.
The model utility content
The utility model is at the drawback of prior art, provides a kind of trench with prefabricated polyurethane foam insulation joint.
Trench described in the utility model is with prefabricated polyurethane foam insulation joint, be used to connect the joint of two sections prefabricated polyurethane foam insulation pipes, joint at two sections prefabricated polyurethane foam insulation pipes coats the polyurethane foam tile fragment, tightens up with pyrocondensation belt outside the described polyurethane foam tile fragment.
Trench described in the utility model is with in the prefabricated polyurethane foam insulation joint, and described polyurethane foam tile fragment is a plurality of, and described a plurality of polyurethane foam tile fragment splices each other.Further, splicing place of described a plurality of polyurethane foam tile fragments is provided with the ladder platform, and the ladder platform of adjacent two polyurethane foam tile fragments cooperatively interacts.
Trench described in the utility model is with in the prefabricated polyurethane foam insulation joint, and the polyurethane foam tile fragment of described a plurality of splicings is fastened with gummed paper tapes.
Trench described in the utility model adopts the thermal insulating material of polyurethane foam as joint with in the prefabricated polyurethane foam insulation joint, has well promoted thermal insulation property, and simultaneously, joint structure described in the utility model is simple to operation, and effect is obvious.
Description of drawings
Fig. 1 is the cross-sectional schematic of trench described in the utility model with prefabricated polyurethane foam insulation joint;
Fig. 2 is trench described in the utility model another cross-sectional schematic with prefabricated polyurethane foam insulation joint.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification literal to make those skilled in the art.
As shown in Figure 1 and Figure 2, trench described in the utility model is with prefabricated polyurethane foam insulation joint, be used to connect the joint 1,2 of two sections prefabricated polyurethane foam insulation pipes, all be coated with polyurethane foam outside the joint 1,2 of these two sections prefabricated polyurethane foam insulation pipes, then only there is exposed body the end of joint.The utility model promptly is used to seal this exposed body portion.Particularly, coat polyurethane foam tile fragment 3, tighten up with pyrocondensation belt 4 outside the described polyurethane foam tile fragment 3 in the joint of two sections prefabricated polyurethane foam insulation pipes.
Be the straight line path of blocking radiant heat, in the utility model, also described polyurethane foam tile fragment 3 be set to a plurality ofly that and described a plurality of polyurethane foam tile fragment 3 splices each other.For example, splicing place of described a plurality of polyurethane foam tile fragments 3 can be provided with ladder platform 6, the ladder platform 6 of adjacent two polyurethane foam tile fragments cooperatively interacts, to guarantee the level and smooth splicing of adjacent two polyurethane foam tile fragments.
Working procedure of the present utility model is as follows:
Described polyurethane foam tile fragment 3 is prefabricated in the factory, this prefabricated tile fragment longitudinal size is slightly larger than the length of the exposed joint of two sections prefabricated polyurethane foam insulation pipes, on-the-spot section cuts tile fragment according to the actual interface situation, and tile fragment is combined closely with prefabricated polyurethane insulation coating; Difference according to caliber on the tile fragment hoop is divided into polylith, and it is step-like to utilize the linear cutting machine device to be cut into, the interlock degree when guaranteeing on-the-spot the splicing, and reduce the heat dissipation that bring in the slit.Use gummed paper tapes 5 hoops to be fastened firmly after the tile fragment assembly unit.Cut pyrocondensation belt 4 by caliber, and the position of using sand papering pyrocondensation belt 4 and prefabricated high density polyethylene (HDPE) housing contacts, use the rag wiped clean of dry oil free after the removal shell oxide layer, to carrying out the shrink belt shrinkage operation after the high density polyethylene pipe preheating, guarantee during contraction that lap-joint's sealing is closely tight again.
Trench described in the utility model adopts the thermal insulating material of polyurethane foam as joint with in the prefabricated polyurethane foam insulation joint, has well promoted thermal insulation property, and simultaneously, joint structure described in the utility model is simple to operation, and effect is obvious.
Described polyurethane foam heat insulation material can keep its performance in the working life in 30 years.And the polyurethane foam tile fragment adopts the fluorine-free and environment-friendly foaming system, and at high temperature volatile matter does not seldom influence the environment in the trench.Adapter assembly described in the utility model is prefabricated in the factory, steady quality; Site operation is easy, and construction amount reduces, and shortens the heat preservation construction cycle significantly.Simultaneously, can reduce the workload of operation maintenance, Security also is improved.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in specification and the mode of execution, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
