Description

Technical Field

[0001] This utility model relates to the field of insulation board technology, and in particular to a spliced ​​building exterior wall insulation board. Background Technology

[0002] With the acceleration of modern urbanization and the promotion of green and energy-saving concepts, the requirements for energy-saving and environmentally friendly performance in buildings are constantly increasing, and the thermal insulation effect of building exterior walls has a significant impact on overall energy consumption. To achieve effective thermal insulation of building exterior walls, exterior wall insulation panels are typically installed on the building facade, thereby reducing the conduction of hot and cold air and improving the stability of the indoor thermal environment. In addition to good thermal insulation performance, exterior wall insulation panels must also possess comprehensive properties such as weather resistance, fire resistance, and structural strength to meet the usage requirements of different building environments. To facilitate transportation, installation, and maintenance, more and more projects are adopting modular, assembled exterior wall insulation panels to improve construction efficiency and project quality.

[0003] Existing building exterior wall insulation boards mainly use polystyrene (EPS), extruded polystyrene (XPS), rigid polyurethane foam, and rock wool boards as the insulation core layer, and are usually fixed to the building exterior wall by bonding or mechanical anchoring. To improve installation efficiency and insulation continuity, some insulation boards are designed with tongue and groove, interlocking structures, or connectors on the edges to achieve rapid splicing and sealing. Some products also have a protective layer on the surface of the board to enhance weather resistance and structural strength. Although existing insulation boards can be modularly installed by splicing, due to the lack of a reliable structural reinforcement mechanism, the joints between the boards are prone to loosening or misalignment due to wind pressure or thermal expansion and contraction during long-term use, affecting the overall stability and durability of the wall. Therefore, a spliced ​​building exterior wall insulation board is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a spliced ​​building exterior wall insulation board, which aims to improve the problem that the existing technology lacks a reliable structural reinforcement mechanism and that the connection parts between the boards are prone to loosening or misalignment due to wind pressure or thermal expansion and contraction during long-term use, affecting the overall stability and durability of the wall.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A spliced ​​building exterior wall insulation board includes wall panels and I-beams. The I-beams are disposed between the wall panels, and pressure strips are fixedly connected inside the I-beams. The wall panels have grooves inside, and the sidewalls of the pressure strips are slidably connected inside the grooves. The sidewalls of the wall panels are slidably connected inside the I-beams.

[0007] As a further description of the above technical solution:

[0008] A recessed hole is provided on one side of the wall panel, and a pin is fixedly connected to the side of the wall panel away from the recessed hole.

[0009] As a further description of the above technical solution:

[0010] The pin fits into the recessed hole, and a decorative groove is provided inside the wall panel.

[0011] As a further description of the above technical solution:

[0012] The wall panel has a waterproof layer, a heat insulation layer, a thermal insulation layer, and a sound insulation layer arranged from top to bottom inside.

[0013] As a further description of the above technical solution:

[0014] The waterproof layer is made of polyethylene film and is used to prevent moisture from penetrating into the wall.

[0015] As a further description of the above technical solution:

[0016] The insulation layer is made of rock wool and is used to maintain indoor temperature.

[0017] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the I-beam and pressure strip structure set between the wall panels not only achieves a stable splicing between the panels, but also enhances the wind pressure resistance and structural strength of the entire wall. The slotted connection between the I-beam and the pressure strip can effectively prevent loosening caused by thermal expansion and contraction, and improve the overall stability and service life of the wall.

[0031] 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.

[0032] Reference Figures 1-5This utility model provides an embodiment of a spliced ​​building exterior wall insulation board, including wall panels 1 and I-beams 2. The I-beams 2 are disposed between the wall panels 1, serving to connect and stabilize them, effectively improving the overall wind pressure resistance and structural strength of the wall. Pressure strips 3 are fixedly connected inside the I-beams 2, enhancing the connection tightness of the wall panels 1 and preventing structural loosening due to thermal expansion and contraction. A groove 4 is provided inside the wall panel 1 to accommodate the sidewall of the pressure strip 3. The sidewall of the pressure strip 3 slides within the groove 4, making the splicing between the wall panels 1 smoother and providing good ease of assembly and disassembly, improving construction efficiency and reducing labor costs. The sidewall of the wall panel 1 slides within the I-beams 2, forming a stable slotted connection structure, further enhancing the overall stability of the wall. A recessed hole 5 is provided on one side of the wall panel 1, with the wall panel 1 positioned away from the recessed hole 5. The side is fixedly connected with a pin 6, which fits into the recessed hole 5 to achieve quick splicing and positioning between wall panels 1, effectively preventing misalignment or loosening of the panels and improving the airtightness and safety after installation. The interior of the wall panel 1 has a decorative groove 7, which beautifies the surface of the panel. The interior of the wall panel 1 is provided with a waterproof layer 8, a heat insulation layer 9, a thermal insulation layer 10 and a sound insulation layer 11 from top to bottom. The waterproof layer 8 is made of polyethylene film and is used to prevent moisture from penetrating into the wall, thereby extending the life of the wall and preventing mold and corrosion. The heat insulation layer 9 is made of rock wool, which has good thermal inertia and can effectively block the conduction of external heat to maintain the indoor temperature. The thermal insulation layer 10 is made of polyurethane material and is used to increase the thermal resistance of the wall and reduce the loss of indoor heat. The sound insulation layer 11 is made of sound insulation foam and is used to reduce sound transmission and improve the indoor acoustic environment.

[0033] Working principle: When splicing multiple wall panels 1, firstly, the I-beam 2 is placed between adjacent wall panels 1, allowing the side wall of the wall panel 1 to slide into the internal groove of the I-beam 2, forming a preliminary connection. At the same time, the pressure strip 3 is inserted into the pre-set groove 4 inside the wall panel 1, realizing the connection between the wall panel 1 and the I-beam 2, enhancing the tightness and deformation resistance between the panels. Next, by inserting the pin 6 set on each wall panel 1 into the recessed hole 5 of the adjacent wall panel 1, quick positioning and locking are further achieved, preventing the wall panels 1 from being misaligned or loosened during use. This connection method not only improves the structural stability and wind pressure resistance of the overall wall, but also facilitates quick assembly and disassembly on site, improving construction efficiency.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
