Technical Field
[0001] The utility model belongs to the technical field of building water heating, and particularly relates to an axial multi-position positioning device adapted to heating pipes in old residential areas in cold regions. Background Technique
[0002] The heating pipelines in old residential areas are in disrepair due to long years of use and have been in a low-temperature disaster area in recent years. To further ensure the heating safety of residents and improve the winter heating environment of residents, it is imperative to transform the heating pipelines in old residential areas. The heating pipelines in old residential areas have exceeded their service life and are severely aged, and there are problems such as running, dripping, and leaking in the pipelines. The water loss in the pipelines is large, and the conveying capacity has decreased significantly. This not only wastes energy, but also affects the heating effect and there are potential safety hazards. Solving the problems of "running, dripping, and leaking" in old heating pipe networks such as heating can improve the bearing capacity and reduce potential safety hazards. During the current renovation process of old residential areas, one of the important tasks involved is the renovation and replacement of the heating water pipes in the corridors. Inevitably, the heating water pipes need to penetrate the floor slabs of each floor. Therefore, the fixed installation structure of the heating water pipes passing through the floor slabs has attracted more and more attention from construction parties, contractors, and residents. The existing construction method is to directly drill holes in the floor slab, and the heating water pipes are arranged through the holes. After filling the gap between the holes and the heating water pipes with thermal insulation materials, it is leveled with cement mortar. However, after using this common and popular construction method in cold regions with large temperature differences between seasons and day and night, the following disadvantages are found:
[0003] First, after using for more than one year, in cold regions, due to the large temperature difference between indoor and outdoor, the temperature difference between the corridor and the outside, and the temperature difference between the corridor and the indoor of the residents, cracks will appear between the cement mortar and the floor slab. Water is likely to enter through the cracks, causing water to seep into the floor slab from the upper side of the floor slab and flow to the lower side of the floor slab, resulting in the peeling of the plaster layer of the floor slab due to water seepage.
[0004] Second, when there are water droplets on the outer wall of the heating water pipe, the water will flow down along the heating water pipe and flow out from between the heating water pipe and the thermal insulation material filled in the gap, resulting in the direct destruction of the waterproof performance.
[0005] Third, no waterproof treatment is carried out between the heating water pipe and the floor slab, and there is a potential leakage hazard in the gap between the hole and the heating water pipe, and the waterproof performance is poor.
[0006] Fourth, the heating water pipe cannot achieve its own heat preservation and anti-scalding. When the temperature is too high, the relevant filling materials filled in the corridor holes are prone to deformation and generate gaps. Seriously, caking will occur, and the filling materials in the circumferential gaps will partially or completely fall off, resulting in the lack of circumferential support for the heating water pipe and causing micro-movement deviation.
