Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermal insulation building technology, specifically to a prefabricated floor slab with a door thermal break bridge. Background Technology
[0002] With the increasing severity of global climate change and energy issues, energy conservation and emission reduction in the construction industry have become a focus of social attention. In traditional buildings, floor slabs are typically made of heavy materials such as concrete. While these materials offer structural stability, they perform poorly in terms of thermal performance. Especially at the junctions between the floor slab and the building's external structure—such as walls and doors—heat is significantly lost through these "thermal bridges," leading to a decrease in the indoor-outdoor temperature difference and thus increasing the building's energy consumption. Furthermore, the inadequate sound insulation of traditional floor slabs is a major drawback, affecting the quietness and comfort of living or working spaces.
[0003] In traditional building construction, floor slabs are mostly constructed by pouring concrete on-site. This method is not only time-consuming and labor-intensive, but also prone to quality control due to numerous uncertainties during construction, which in turn affects the building's durability and functionality. Furthermore, traditional floor slabs present many inconveniences in later maintenance and renovation, such as high repair costs and difficulty in modification, which are detrimental to the long-term use and maintenance of the building.
[0004] To address these issues, the industry has gradually developed various thermal insulation and sound insulation materials, as well as prefabricated building technologies. While these new materials and technologies have improved the thermal performance and construction efficiency of buildings to some extent, problems remain, such as high cost, complex construction processes, and unsatisfactory thermal and sound insulation effects. In particular, the problem of "thermal bridges" at the connection between doors and floor slabs has long remained unresolved. Utility Model Content
[0005] The purpose of this utility model is to provide a prefabricated floor slab with a door thermal break bridge to address the problems mentioned above.
[0006] The technical solution adopted by this utility model is as follows: a prefabricated floor slab with a door thermal break bridge, including a floor slab and a door set on the floor slab, a thermal break bridge is set between the door and the floor slab, a PE board is set at the bottom of the thermal break bridge, an aerogel thermal insulation coating layer is set on the side of the door near the outside, and an aerogel felt layer is set between the floor slab and the thermal break bridge.
[0007] Furthermore, a sealing strip is provided at the corner of the thermal break bridge.
[0008] Furthermore, a silicone weather-resistant structural adhesive layer is installed at the connection between the thermal break bridge and the PE board at the end closest to the outside.
[0009] Furthermore, the thickness of the aerogel insulation coating layer is set to 2-4 mm.
[0010] Furthermore, the thickness of the PE board is set to 35mm.
[0011] Furthermore, the floor slab includes, from top to bottom, a PE board, an epoxy resin adhesive layer, a silica vacuum insulation board, another epoxy resin adhesive layer, another silica vacuum insulation board, another epoxy resin adhesive layer, sound insulation felt, waterproof membrane, metal outer shell panel, and frame steel beams.
[0012] Furthermore, the thickness of the PE board used for the floor slab is set to 20mm.
[0013] Furthermore, the thickness of the silica vacuum insulation board is set to 15mm.
[0014] Furthermore, the thickness of the sound insulation felt is set to 3mm.
[0015] Furthermore, the thickness of the waterproof membrane is set to 2mm.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0017] 1. High-efficiency thermal insulation: By setting up a thermal break bridge between the door and the floor, placing a PE board at the bottom of the thermal break bridge, and applying an aerogel thermal insulation coating layer on the side of the door facing the outside, the direct heat transfer path is effectively blocked, significantly reducing heat loss and improving the thermal insulation performance of the floor.
[0018] 2. Excellent sound insulation performance: The aerogel felt layer between the floor slab and the thermal break bridge, as well as the sound insulation felt design inside the floor slab, work together to form an effective sound insulation layer, significantly improving the building's sound insulation effect.
[0019] 3. Energy saving and environmental protection: The structural design of this utility model reduces energy loss and building energy consumption, which helps to reduce the impact on the environment and is in line with the concept of sustainable development.
[0020] 4. Easy installation and simple maintenance: The design of prefabricated floor slabs makes the installation process faster and more convenient, and also facilitates later maintenance and renovation, improving the flexibility and service life of the building. Attached Figure Description

Detailed Implementation
[0023] The present invention will now be described in detail with reference to the accompanying drawings.
[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0025] In this embodiment, as Figure 1 As shown, a prefabricated floor slab with a door thermal break bridge includes a floor slab 1 and a door 3 disposed on the floor slab 1. A thermal break bridge 2 is disposed between the door 3 and the floor slab 1. A PE board 4 is disposed at the bottom of the thermal break bridge 2. An aerogel thermal insulation coating layer 5 is disposed on the side of the door 3 near the outside. An aerogel felt layer 6 is disposed between the floor slab 1 and the thermal break bridge 2.
[0026] This invention utilizes a prefabricated floor slab system with a door 3 and a thermal break bridge 2. The thermal break bridge 2, made of 70-series outward-opening insulated aluminum alloy, is installed between the floor slab 1 and the door 3, and incorporates a PE board 4 and an aerogel insulation coating layer 5. This structure effectively blocks heat transfer through the gaps in the door 3, achieving highly efficient thermal insulation. Simultaneously, the addition of the aerogel felt layer 6 significantly improves the sound insulation performance of the floor slab 1, providing residents with a quieter and more comfortable living environment.
[0027] Furthermore, a sealing strip 7 is provided at the corner of the thermal break bridge 2.
[0028] Sealing strips 7 were added to the corners of the thermal break bridge 2 in floor slab 1 to further improve the structure's airtightness and thermal insulation. This improvement makes the overall building's insulation performance even better, especially in winter, as indoor heat is less likely to dissipate, reducing the burden on the heating system.
[0029] Furthermore, a silicone weather-resistant structural adhesive layer 8 is provided at the connection between the thermal break bridge 2 and the PE board 4 at the end closest to the outdoors.
[0030] A silicone weather-resistant structural adhesive layer 8 was used at the connection between the thermal break bridge 2 and the PE board 4, near the outdoor end. This design enhances the weather resistance of the floor slab 1 system, ensures thermal insulation performance under harsh weather conditions, and also extends the building's service life.
[0031] Furthermore, the thickness of the aerogel insulation coating layer 5 is set to 2-4 mm.
[0032] A specific thickness of aerogel insulation coating layer 5 and PE board 4 were specified. This design optimizes the thermal insulation performance of floor slab 1 while ensuring the structural strength and stability of floor slab 1, meeting the requirements for environmental comfort and durability.
[0033] Furthermore, the thickness of PE board 4 is set to 35mm.
[0034] Furthermore, the floor slab 1 includes, from top to bottom, a PE board 4, an epoxy resin adhesive layer 9, a silica vacuum insulation board 10, an epoxy resin adhesive layer 9, a thick silica vacuum insulation board 10, an epoxy resin adhesive layer, a sound insulation felt 11, a waterproof membrane 12, a metal outer shell 13, and a frame steel beam 14.
[0035] By employing materials such as silica vacuum insulation board 10, epoxy resin adhesive layer 9, sound insulation felt 11, and waterproof membrane 12, floor slab 1 not only possesses excellent thermal insulation performance but also superior sound insulation. These characteristics ensure a quiet and comfortable environment inside the library, providing users with a pleasant space.
[0036] Furthermore, the PE board 4 used in floor slab 1 is set to a thickness of 20mm.
[0037] Furthermore, the thickness of the silica vacuum insulation board 10 is set to 15mm.
[0038] The use of PE board 4 of specific thickness and silica vacuum insulation board 10 greatly shortened the construction cycle while ensuring the building's thermal insulation and sound insulation performance, thus meeting the requirements for indoor environmental quality.
[0039] Furthermore, the thickness of the sound insulation felt 11 is set to 3mm.
[0040] The sound insulation felt 11 in the floor slab system is set to a thickness of 3mm. This design effectively improves the acoustics inside the building and enhances the user experience.
[0041] Furthermore, the thickness of the waterproof membrane 12 is set to 2mm.
[0042] The 12 layers of 2mm thick waterproof membrane effectively prevented moisture penetration, ensuring that the floor structure in these high-humidity areas was not corroded by water vapor and extending the service life of the building.
[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
