Technical Field
[0001] The utility model belongs to the technical field of modular buildings, and in particular relates to a building unit in which heating pipes are connected between adjacent modules of a modular building. Background Art
[0002] Modular construction is a technology that has emerged when prefabricated buildings have developed to a considerable extent. It can complete the construction, structure, electromechanical, and decoration professions in the factory, and then transport the modules to the site for installation. This technology can minimize on-site operations. Among them, the hexahedral module is a box module that is prefabricated in the factory with six surfaces including the bottom surface. Radiator heating is the most commonly used form of heating. The main methods for laying the heating pipes of the radiator indoors are open laying indoors and direct burial in the cushion layer. If direct burial is used, it is usually carried out after the main structure is completed, and the heating pipes can be completed at one time. For modular buildings, after the heating pipes in the module are laid in the factory, the heating pipes of different modules need to be connected during on-site assembly, which cannot be completed at one time.
[0003] However, the current splicing of heating pipes between modules will leave connectors in the cushion layer, affecting the need to repair problems at the connectors in the future, and violating relevant design specifications. Utility Model Content

[0028] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.
[0029] like Figure 1-2 As shown, the utility model provides a building unit for connecting heating pipes between adjacent modules of a modular building, including two adjacent hexahedral modules, a connector 4, an inspection box 5 and a plurality of plastic pipe clamps 6. The hexahedral module includes a cushion layer 1 and a structural layer 7 located on its bottom surface. The cushion layer 1 is in contact with the structural layer 7 and is located above the structural layer 7. It includes a cement mortar cushion layer 11, a composite silicate thermal insulation material layer 12 and a polystyrene board thermal insulation layer 13 sequentially laid from top to bottom. The heating pipe 2 is directly buried in the composite silicate thermal insulation material layer 12.
[0030] A module joint 3 is left between the two hexahedral modules. No building cushion layer and decorative surface layer are formed at the module joint 3 on the hexahedral module to form a first notch 14. The first notch 14 is located between the cement mortar cushion layer 11 and the composite silicate insulation material layer 12 to expose part of the heating pipe 2. The first notches 14 of two adjacent hexahedral modules are symmetrical about the module joint 3 and aligned with each other to form a second notch 15. The bottom wall of the second notch 15 is a polystyrene board insulation layer 13.
[0031] The size range of the first notch 14 is: 350mm×150mm~450mm×250mm to ensure that there is sufficient operating space between adjacent hexahedral modules on site to connect the heating pipe 2.
[0032] It should be noted that the second notch 15 should be located away from the wall area of the modular building.
[0033] The material of the inspection box 5 is PVC or galvanized steel, including a bottom plate 51, a box body 52 and a top plate 55, and the top plate 55 is detachably connected to the box body 52. First, the connector 4 is sleeved on the outside of the ends of the two heating pipes 2, and the two heating pipes 2 are hot-melt connected, and then all the plastic pipe clamps 6 are sleeved on the outside of the heating pipes 2 at equal distances, and both ends of all the plastic pipe clamps 6 are fixed to the bottom wall of the second notch 15 to fix the heating pipes 2, and then the bottom plate 51 is located directly below the connector 4 and straddled on the module joint 3 and set on the bottom wall of the second notch 15.
[0034] like Figure 2 As shown, the two side walls of the box body 52 are provided with holes 53 adapted to the heating pipe 2 so that when the box body 52 and the bottom plate 51 are buckled together, the connector 4 can be wrapped to form an inspection space 54. The gap between the hole 53 and the heating pipe 2 is filled with sealant to separate the connector 4 from the cushion layer 1.
[0035] It should be noted that the height of the inspection box 5 is consistent with the height of the cushion layer 1 .
[0036] Finally, a composite silicate thermal insulation material layer 12 and a cement mortar cushion layer 11 are poured into the second notch 15 to make the structure in the second notch 15 consistent with the architectural structure of the cushion layer 1, and the completed pouring height of the cement mortar cushion layer 11 in the second notch 15 is flush with the top plate 55 to prevent the top plate 55 from being covered.
[0037] In addition, a surface layer such as a floor or a threshold stone is installed on the top plate 55 .
[0038] The specific implementation steps of the utility model are:
[0039] 1. The direct burial laying of the hexahedral module heating pipe 2 is completed in advance in the factory, and the cushion layer 1 and the decorative surface are completed at the same time, and the first notch 14 is reserved at the module joint. The specific size of the first notch 14 should be adjusted according to the floor shape.
[0040] 2. Leave a module joint 3 between two adjacent hexahedral modules to complete the splicing of adjacent hexahedral modules, so that the first notches 14 of the two adjacent hexahedral modules correspond to each other to form a second notch 15. The second notch 15 should avoid the wall area of the modular building.
[0041] 3. Sleeve the connector 4 on the outside of the ends of the two heating pipes 2, and use the connector 4 to hot-melt to connect the heating pipes 2 between the two hexahedral modules.
[0042] 4. The plastic pipe clamps 6 are equidistantly sleeved on the outside of the heating pipe 2 and both ends of all the plastic pipe clamps 6 are fixed to the bottom wall of the second notch 15 to fix the heating pipe 2.
[0043] 5. Place the bottom plate 51 below the connector 4 and straddle the bottom wall of the module joint 3 disposed at the second notch 15 .
[0044] 6. Then buckle the box body 52 onto the bottom plate 51 to complete the connection. The top plate 55 can be disassembled to prevent the connector 4 from leaking and requiring repair.
[0045] 7. Fill the composite silicate thermal insulation material layer 12 and the cement mortar cushion layer 11. It should be noted that the finished height of the cement mortar cushion layer 11 is consistent with the height of the inspection box 5 and cannot cover the top plate 55 to avoid affecting the opening of the inspection box 5.
[0046] 8. Install the floor or threshold stone for surface laying and record the position of the inspection box 5. If the heating pipe 2 leaks later, turn over the surface layer and open the top plate 55 to inspect the heating pipe 2.
