Description

Technical Field

[0001] This utility model relates to the field of building roof insulation technology, specifically to an extruded polystyrene board for green building roof insulation. Background Technology

[0002] In today's society, with the concept of sustainable development gaining widespread acceptance, green building, as an important development direction for the construction industry, is receiving increasing attention. Green building emphasizes maximizing resource conservation (energy saving, land saving, water saving, and material saving), protecting the environment, and reducing pollution throughout the building's entire life cycle, providing people with healthy, suitable, and efficient living spaces, and achieving harmonious coexistence with nature. Among these, roof insulation, as a key component of energy-saving design in green buildings, plays a crucial role in improving the building's energy efficiency and reducing energy consumption.

[0003] Currently, roofing construction still uses traditional methods, requiring on-site manual labor for each step, such as laying insulation layers and pouring concrete. This makes the construction process complex, the construction period long, and requires a large number of manual workers. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] This invention provides an extruded polystyrene board for roof insulation in green buildings, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an extruded polystyrene board for roof insulation in green buildings, comprising a bottom frame, an extruded layer, a waterproof layer, a finishing layer, and several nuts. The extruded layer, waterproof layer, and finishing layer are stacked sequentially from bottom to top within the bottom frame, and the finishing layer extends above the bottom frame. The nuts are connected to the bottom frame and used to fix the extruded layer, waterproof layer, and finishing layer, thereby forming a modular roof unit structure among the bottom frame, extruded layer, waterproof layer, and finishing layer.

[0008] Preferably, the bottom frame includes an outer frame, a rib grid, positioning plates and positioning studs in equal numbers to the number of nuts. The inner cavity of the outer frame extends upward and downward through the outer frame. The rib grid is fixedly connected to the bottom opening of the outer frame. Several positioning plates are embedded in the rib grid and fixedly connected to it. The lower ends of several positioning studs pass through adjacent positioning plates, and the upper end of each positioning stud is provided with an external thread that mates with the nut.

[0009] In a further preferred embodiment, both the extruded layer and the waterproof layer are provided with positioning holes, and the extruded layer and the waterproof layer are sleeved on the outside of a plurality of positioning studs through the positioning holes. The waterproof layer is made of polyvinyl chloride board or polyethylene board, and the joint between the waterproof layer and the outer frame is provided with sealant.

[0010] In a further preferred embodiment, at least one water channel is formed on the top surface of the finishing layer, penetrating the finishing layer.

[0011] In a further preferred embodiment, when assembling several sets of modular roof unit structures, the gap between two adjacent finishing layers constitutes a pouring joint, and concrete is poured into the pouring joint.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides an extruded polystyrene board for roof insulation in green buildings, which has the following beneficial effects:

[0014] In this invention, by sequentially stacking the extruded polystyrene layer, waterproof layer, and finishing layer within the bottom frame to form a modular roof unit structure, the construction process of the roof insulation system becomes more standardized and regulated. Construction workers only need to assemble several sets of modular roof unit structures to complete the installation of the roof insulation system, greatly simplifying the construction process, shortening the construction cycle, reducing labor and material inputs, and lowering construction costs.

[0015] In addition, when the roof insulation system is partially damaged, due to the modular design, only the corresponding modular roof unit structure needs to be replaced, eliminating the need for large-scale repairs to the entire roof and greatly reducing the difficulty and cost of maintenance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 and Figure 2 An extruded polystyrene (XPS) board for roof insulation in green buildings includes a bottom frame 10, an extruded polystyrene (XPS) layer 20, a waterproof layer 30, a finishing layer 40, and several nuts 50. The XPS layer 20, waterproof layer 30, and finishing layer 40 are stacked sequentially from bottom to top within the bottom frame 10, with the finishing layer 40 extending above the bottom frame 10. The nuts 50 connect with the bottom frame 10 and are used to secure the XPS layer 20, waterproof layer 30, and finishing layer 40, forming a modular roof unit structure.

[0023] See Figure 3 The bottom frame 10 includes an outer frame 11, a reinforcing mesh 12, positioning plates 13 (equal in number to nuts 50), and positioning studs 14. The inner cavity of the outer frame 11 extends upwards and downwards through the frame. The reinforcing mesh 12 is fixedly connected to the bottom opening of the outer frame 11. Several positioning plates 13 are embedded in and fixedly connected to the mesh of the reinforcing mesh 12; in the figure, the positioning plates 13 are located in the corner meshes of the reinforcing mesh 12. The lower ends of several positioning studs 14 pass through adjacent positioning plates 13, and the upper end of each positioning stud 14 is provided with external threads that mate with the nuts 50. The positioning studs 14 can be pre-fixed to the roof during construction. Then, during the installation of the modular roof unit structure, the positioning studs 14 are used to position each modular roof unit structure. After installation, the nuts 50 are tightened onto the positioning studs 14 to complete the fixing of the modular roof unit structure.

[0024] In this embodiment, positioning holes are provided on both the extruded polystyrene layer 20 and the waterproof layer 30, so that when the modular roof unit structure is laid and placed, the extruded polystyrene layer 20 and the waterproof layer 30 can be fitted onto the outside of several positioning studs 14 through the positioning holes and placed inside the outer frame 11.

[0025] In this embodiment, the waterproof layer 30 is made of polyvinyl chloride or polyethylene board, and a sealant is provided at the joint between the waterproof layer 30 and the outer frame 11, thereby reducing the impact of water ingress on the extruded layer 20.

[0026] In this embodiment, at least one water channel penetrating the finishing layer 40 is formed on the top surface of the finishing layer 40. After several sets of modular roof unit structures are laid on the roof, rainwater can be discharged to the outer edge of the house by means of the connected water channel.

[0027] See Figure 4 After several sets of modular roof unit structures are assembled and fixed, the gaps between two adjacent finishing layers 40 can be used to form a pouring joint 60, and concrete is poured into the pouring joint 60 to make the connection of several sets of modular roof unit structures more stable and reduce water infiltration.

[0028] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as bonding, welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, bonding and welding are preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
