Description
Technical Field
[0001] The present application relates to the technical field of building construction, and particularly relates to a node suitable for electrical pipelines to pass through the roof of a nearly zero - energy consumption building. Background Art
[0002] With the increasing attention of people to building energy consumption problems, nearly zero - energy consumption buildings, as an efficient energy - saving building form, have received extensive attention. In nearly zero - energy consumption buildings, the design of the node where electrical pipelines pass through the roof is particularly important, which not only relates to the thermal insulation performance of the building, but also directly affects the service life and living comfort of the building. However, the existing designs of the nodes where electrical pipelines pass through the roof often have problems such as complex construction procedures and poor treatment of thermal bridges, resulting in damage to the thermal insulation performance of the building and being unable to meet the high standards of nearly zero - energy consumption buildings. Utility Model Content
[0003] In order to improve the thermal insulation performance of the node where electrical pipelines pass through the roof, the present application provides a node suitable for electrical pipelines to pass through the roof of a nearly zero - energy consumption building.
[0004] The node suitable for electrical pipelines to pass through the roof of a nearly zero - energy consumption building provided by the present application adopts the following technical solutions:
[0005] A node suitable for electrical pipelines to pass through the roof of a nearly zero - energy consumption building includes a base floor slab. A sleeve penetrates through the base floor slab. Above the base floor slab, a thermal insulation and waterproof structure is provided, and the thermal insulation and waterproof structure includes a plurality of thermal insulation and waterproof layers arranged in sequence. A thermal insulation filling layer is provided between the sleeve and the base floor slab.
[0006] By adopting the above - mentioned technical solution, setting a plurality of thermal insulation and waterproof layers can reduce the heat exchange between the two spaces above and below the base floor slab and simultaneously play a waterproof role. Moreover, when the sleeve penetrates through the base floor slab, the thermal insulation filling layer provided between the sleeve and the base floor slab can further reduce the loss of heat.
[0007] Preferably, a thermal insulation layer is sleeved on the outer side of the bottom end of the sleeve located under the base floor slab.
[0008] By adopting the above - mentioned technical solution, the thermal insulation layer provided on the outer side of the sleeve can effectively reduce the loss of heat through the gap between the sleeve and the base floor slab, thereby improving the overall thermal insulation effect.
[0009] Preferably, a concrete protective layer is provided at the top of the thermal insulation and waterproof structure away from the base floor slab.
[0010] By adopting the above - mentioned technical solution, the concrete protective layer can play a certain protective role for the multi - layer thermal insulation and waterproof structure and try to avoid damage to the thermal insulation and waterproof structure.
[0011] Preferably, sealant is filled between the casing and the concrete thermal insulation layer.
[0012] By adopting the above technical solution, the primary function of the sealant is waterproof sealing. Since there may be tiny gaps between the casing and the concrete protective layer, if these gaps are not sealed, they are likely to become channels for water penetration. The sealant can fill these gaps to form a waterproof barrier, preventing water from penetrating into the thermal insulation and waterproof structure through the gaps and ensuring the waterproof performance of the structure.
[0013] Preferably, an additional waterproof coiled material layer is further included. The additional waterproof coiled material is arranged between adjacent thermal insulation and waterproof layers and is disposed close to the casing.
[0014] By adopting the above technical solution, arranging the additional waterproof coiled material layer close to the casing can focus on protecting the waterproof weak area around the casing, thereby significantly improving the waterproof performance of the entire thermal insulation and waterproof structure.
[0015] Preferably, a waterproof and airtight film is provided at the junction of the casing and the bottom surface of the base floor slab. One end of the waterproof and airtight film is arranged outside the casing, and the other end of the waterproof and airtight film is pasted on the bottom of the base floor slab.
[0016] By adopting the above technical solution, the waterproof and airtight film itself has excellent waterproof performance and can effectively prevent water from entering the gap between the casing and the base floor slab.
[0017] Preferably, a kit is further included, and one end of the kit is sleeved on the top end of the casing away from the base floor slab.
[0018] By adopting the above technical solution, the kit provides thermal insulation ability for the casing, further reducing heat loss.
[0019] Preferably, multiple thermal insulation and waterproof layers are made of different materials.
[0020] By adopting the above technical solution, using thermal insulation and waterproof layers of different materials can optimize the thermal insulation effect according to the characteristics of each layer of material.
[0021] In summary, the present application includes at least one of the following beneficial technical effects:
[0022] 1. Using thermal insulation and waterproof layers of different materials can form multiple lines of defense, providing more reliable thermal insulation and waterproof performance. Each material has its unique thermal insulation and waterproof characteristics. By using them in combination, the loss or penetration of heat and water can be minimized, thereby improving the energy utilization efficiency and waterproof safety of the building;
[0023] 2. By providing an additional waterproof membrane layer, a waterproof air-barrier membrane and a thermal insulation filling layer, the gaps between the casing and the base floor and between the casing and the thermal insulation and waterproof structure can be insulated, thereby minimizing heat loss from the gaps.

DETAILED DESCRIPTION
[0029] The following is combined with Figures 1-4 This application is described in further detail.
[0030] An embodiment of the present application discloses a node suitable for an electrical conduit to pass through the roof of a near-zero energy building.
[0031] Reference Figure 1 A node suitable for an electrical pipeline to pass through a roof of a near-zero energy building includes a base floor 1, a sleeve 2 for guiding an electrical pipeline 100 is provided in the base floor 1, and the two ends of the sleeve 2 are respectively located in the lower floor and the upper floor. A thermal insulation and waterproof structure 3 is laid above the base floor 1, and a thermal insulation layer 4 is provided outside the sleeve 2 located below the base floor 1, so as to ensure that the energy loss of the node at the pipeline gap is reduced and improve the thermal insulation performance of the node where the electrical pipeline 100 passes through the roof.
[0032] The base floor slab 1 includes a concrete roof slab 11, a slope-forming layer 12, and a leveling layer 13. The slope-forming layer 12 is arranged above the concrete slab, and the leveling layer 13 is arranged above the slope-forming layer 12. In this embodiment, the slope-forming layer 12 is made of foam concrete, and the leveling layer 13 is formed by laying cement mortar. The slope-forming layer 12 is used to form a certain slope to facilitate drainage; while the leveling layer 13 is used to provide a more flat surface to facilitate the laying of the thermal insulation and waterproof structure 3.
[0033] Referring to Figure 1 and Figure 2 , the thermal insulation and waterproof structure 3 includes four thermal insulation and waterproof layers made of different materials arranged in sequence. The multiple thermal insulation and waterproof layers are respectively set as the first thermal insulation and waterproof layer 31, the second thermal insulation and waterproof layer 32, the third thermal insulation and waterproof layer 33, and the fourth thermal insulation and waterproof layer 34 from bottom to top. The first thermal insulation and waterproof layer 31 is set as a self-adhesive modified bitumen waterproof and vapor barrier coil with an alkali-resistant aluminum foil surface layer and fiberglass base, and the equivalent air thickness of the first thermal insulation and waterproof layer 31 ≥ 1500m. The second thermal insulation and waterproof layer 32 is formed by laying multiple graphite polystyrene boards. The graphite polystyrene boards have a microporous heat insulation structure and a low thermal conductivity, so that heat is not easily transmitted, effectively preventing heat exchange. And, the multiple graphite polystyrene boards are laid in layers, so as to ensure that the graphite polystyrene boards are evenly distributed at multiple levels, further improving the heat insulation effect. The third thermal insulation and waterproof layer 33 is set as a fiberglass base modified bitumen self-adhesive waterproof coil, which has excellent waterproof performance and a certain high-temperature resistance, and can withstand a high temperature of 90°C. The fourth thermal insulation and waterproof layer 34 is formed by laying a slate surface modified bitumen waterproof coil. On the basis of the modified bitumen waterproof coil, the surface of the slate surface modified bitumen waterproof coil is specially treated to make it have the appearance or characteristics of a slate surface.
[0034] The adjacent thermal insulation and waterproof layers are closely bonded using a professional adhesive and a heat treatment tool, ensuring the tight combination between the adjacent thermal insulation and waterproof layers, forming a roof structure with a heat transfer coefficient meeting the requirements of nearly zero energy consumption buildings, thus effectively improving the heat insulation performance of the building.
[0035] Referring to Figure 1 , preferably, a layer of concrete protective layer 5 is also laid above the thermal insulation and waterproof structure 3. By setting the concrete protective layer 5, not only can the strength of the roof be ensured, making the roof more stable to bear the load brought by human activities; at the same time, the concrete protective layer 5 also provides an additional layer of protection for the multiple thermal insulation and waterproof layers, preventing the thermal insulation and waterproof layers from being damaged by external factors as much as possible. And, a caulking paste 51 is filled between the concrete protective layer 5 and the casing 2. The caulking paste 51 can effectively fill the tiny gaps between the concrete protective layer 5 and the casing 2, preventing liquids, gases, or other impurities from penetrating through the gaps, thereby improving the overall sealing performance and waterproofness.
[0036] In addition, refer to Figure 2 , the embodiment of the present application further includes an additional waterproof roll material layer 35. The additional waterproof roll material layer 35 is disposed between the second thermal insulation and waterproof layer 32 and the third thermal insulation and waterproof layer 33, and is disposed close to the casing 2. The additional waterproof roll material layer 35 can form an additional barrier to prevent moisture from penetrating through these weak points.
[0037] Reference Figure 3 In this embodiment, the sleeve 2 is made of PVC material, and a waterproof air-proof membrane 6 is pasted at the joint between the sleeve 2 and the bottom surface of the base floor 1. One end of the waterproof air-proof membrane 6 is pasted on the outside of the pipe, and the other end is pasted on the bottom of the base floor 1, so as to prevent external water vapor from entering the gap between the sleeve 2 and the base floor 1 as much as possible. The insulation layer 4 located below the base floor 1 is set as a rock wool insulation layer 4, and the insulation layer 4 realizes the covering of the sleeve 2 and the electrical conduit 100 exposed outside the sleeve 2 below the base floor 1, thereby reducing the heat loss at the connection between the sleeve 2 and the base floor 1.
[0038] An insulation filling layer 7 is filled between the base floor 1 and the sleeve 2. In this embodiment, the insulation filling layer 7 is configured as foamed polyurethane, which can achieve thermal insulation and fill the gap between the sleeve 2 and the base floor 1 as much as possible through the foaming ability, thereby further improving the insulation and sealing capabilities of the connection between the pipeline and the base floor 1.
[0039] The outer side of the sleeve 2 along its circumference is also provided with a mounting portion 21, and the mounting portion 21 abuts against the upper side of the base floor 1. The mounting portion 21 is fixed to the base floor 1 by thermal insulation bolts 22, so that the sleeve 2 can be stably mounted on the base floor 1.
[0040] Reference Figure 4 In addition, the embodiment of the present application also includes a kit 24, which is in the shape of an arc tube as a whole. One end of the kit 24 is sleeved on the upper end of the sleeve 2, and the other end of the sleeve 2 is used for the outlet of the cable. The end of the kit 24 away from the sleeve 2 is also provided with a clamp and a sealing ring for fixing the electrical conduit 100, so as to limit the position of the cable and play a certain waterproof role. In this embodiment, the kit 24 can be made of a material with a certain elasticity such as weather-resistant rubber, so as to improve the tightness of the connection between the kit 24 and the sleeve 2, and the durability of the weather-resistant rubber is relatively high. By setting the kit 24, the formation of thermal bridges can be blocked as much as possible.
[0041] The implementation principle of a node applicable to the penetration of electrical pipelines through the roof of a nearly zero - energy building in an embodiment of the present application is as follows: A slope - finding layer 12 and a leveling layer 13 are sequentially laid on a concrete roof slab 11 to form a base floor slab 1, and then a thermal insulation and waterproof structure 3 and a concrete protective layer 5 are sequentially laid on the base floor slab 1. Moreover, a sleeve 2 is pre - embedded in the base floor slab 1. By setting an additional waterproof coiled material layer 35 and a waterproof and air - barrier film 6, the overall sealing performance can be improved. By setting a thermal insulation layer 4, a thermal insulation filling layer 7, and a kit 24, the adiabatic performance of the building can be maintained, the thermal insulation performance of the building can be improved, the temperature difference between indoors and outdoors can be reduced, and the living comfort can be improved.
[0042] The above are all preferred embodiments of the present application. Without restricting the protection scope of the present application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
