Description

Technical Field

[0001] This utility model relates to the field of external wall insulation technology, and in particular to an external wall insulation structure for near-zero energy consumption office buildings. Background Technology

[0002] Near-zero energy buildings are buildings that consume almost zero energy; they are a type of building that is low-carbon, environmentally friendly, energy-efficient, and highly effective.

[0003] Currently, in most building exterior wall insulation structures, the insulation layer is fixed and supported by the installation of keel. However, the connection and fixing of the insulation layer mostly adopts the method of pasting or simple anchoring, which lacks effective mechanical limiting measures. Under wind load, temperature stress or seismic action, the insulation layer is prone to slippage, misalignment or even falling off, resulting in a decrease in insulation performance and even causing safety hazards. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a near-zero energy consumption external wall insulation structure for office buildings, addressing the aforementioned problems.

[0005] The technical solution adopted in this utility model is: a near-zero energy consumption office building exterior wall insulation structure, comprising:

[0006] The support frame has multiple mounting openings inside, and a limiting structure is provided on the inner wall of the periphery of the mounting openings;

[0007] Fasteners, located on the support frame, are used to fix the support frame to the wall surface;

[0008] The inner insulation layer is located at the installation opening and is embedded in the limiting structure of the supporting frame on its periphery.

[0009] The outer insulation layer is located on the outer wall of the supporting frame and covers the outside of the inner insulation layer.

[0010] Using the aforementioned technical methods, the support frame is fixed to the wall surface using fasteners. The inner insulation layer is installed within the installation opening of the support frame. The periphery of the inner insulation layer is physically restrained by the limiting structure inside the support frame, reducing the risk of slippage and misalignment due to external factors. Simultaneously, an outer insulation layer covers the outside of the inner insulation layer, forming a multi-layer insulation structure that enhances the insulation effect.

[0011] In some embodiments, the support frame includes horizontal beams, vertical beams, and side beams. The horizontal beams, vertical beams, and side beams are all hollow structures. The horizontal beams are fixed to the wall surface by the fasteners. A pair of horizontally arranged and parallel horizontal beams are provided between a pair of horizontally arranged and parallel vertical beams. Side beams are provided at both ends of the pair of horizontal beams. The ends of the side beams are connected to the ends of the corresponding sides of the horizontal beams. The inner sides of the horizontal beams, vertical beams, and side beams are respectively provided with a first groove, a second groove, and a third groove. The horizontal beams, vertical beams, and side beams enclose each other so that the first groove, the second groove, and the third groove can cooperate to form a frame-shaped limiting structure to limit and support the sides of the inner insulation layer.

[0012] In some embodiments, the crossbeam and the vertical beam are connected by self-tapping screws, and the end of the side beam is provided with an extension platform that can be inserted and engaged with the end of the crossbeam. After the extension platform of the side beam is inserted into the end of the crossbeam, it is fixedly connected by self-tapping screws.

[0013] In some embodiments, the fastener includes an expansion bolt, the side of the beam facing away from the wall is provided with a notch, and the side of the beam near the wall is provided with a plurality of slotted holes spaced axially through the notch, so that the expansion bolt can pass through the slotted holes to fix the beam to the wall.

[0014] In some embodiments, the crossbeam, the vertical beam, and the side beam are all made of aluminum alloy.

[0015] In some embodiments, a decorative outer protective layer is also included, which is disposed on the wall surface of the support frame away from the wall and is located outside the outer insulation layer.

[0016] In some embodiments, both the inner insulation layer and the outer insulation layer are made of insulating rock wool board.

[0017] The beneficial effects of this utility model are:

[0018] 1. The support frame is fixed to the wall using fasteners. The inner insulation layer is installed at the installation opening of the support frame. The limiting structure on the inner perimeter of the support frame provides physical restraint for the inner insulation layer, reducing slippage and misalignment caused by external factors such as wind loads. Simultaneously, an outer insulation layer is applied over the inner insulation layer; the combination of the inner and outer insulation layers further enhances the insulation effect.

[0029] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0030] Combination Figures 1 to 5 As shown, this embodiment is an external wall insulation structure for a near-zero energy office building, including a support frame, fasteners, an inner insulation layer 2, and an outer insulation layer 3. The support frame is fixed to the wall surface by the fasteners. The support frame has multiple installation openings inside, and a limiting structure is provided on the inner wall of the support frame around each installation opening. The inner insulation layer 2 is located at the installation opening of the support frame, and its periphery is correspondingly embedded within the limiting structure of the support frame, which physically limits the inner insulation layer 2. The outer wall of the support frame has the outer insulation layer 3, which covers the outside of the inner insulation layer 2. The inner insulation layer 2 and the outer insulation layer 3 work together to form a multi-layered insulation and protection effect for the wall.

[0031] In some embodiments, the support frame includes horizontal beams 11, vertical beams 12, and side beams 13. All horizontal beams 11, vertical beams 12, and side beams 13 are hollow structures. The horizontal beams 11 are fixed to the wall surface by fasteners. A pair of horizontally arranged and parallel horizontal beams 11 are connected to a pair of vertically arranged and parallel vertical beams 12. Side beams 13 are provided at both ends of each pair of horizontal beams 11, and their ends are connected to the corresponding ends of the horizontal beams 11, thus sealing the ends of the horizontal beams 11. A first groove 111 is provided on the inner wall of the opposite sides of each pair of horizontal beams 11, a second groove 121 is provided on both sides of each pair of vertical beams 12, and a third groove 132 is provided on the inner side of the side beams 13 facing the vertical beams 12. When the horizontal beam 11, vertical beam 12, and side beam 13 are enclosed, the outer surfaces of the horizontal beam 11, vertical beam 12, and side beam 13 are flush, which facilitates the fixing of the outer insulation layer 3 to the outside of the horizontal beam 11, vertical beam 12, and side beam 13. This allows the adjacent first groove 111, second groove 121, and third groove 132 to cooperate to form a frame-shaped limiting structure. The first groove 111, second groove 121, and third groove 132 can all engage with the side of the inner insulation layer 2, thereby providing limiting support for the side of the inner insulation layer 2.

[0032] The limiting structure formed by the first groove 111, the second groove 121, and the third groove 132 achieves a wrapping fixation of the four edges of the inner insulation layer 2, reducing the risk of misalignment caused by wind pressure, vibration, or temperature changes. At the same time, the limiting structure provides a standardized installation benchmark for the insulation layer, ensuring its flatness and verticality.

[0033] Furthermore, the crossbeam 11 and the vertical beam 12 are connected by self-tapping screws. The end of the side beam 13 is provided with an extension platform 131 that can be inserted and engaged with the end of the crossbeam 11. After the extension platform 131 of the side beam 13 is inserted into the end of the crossbeam 11, it is fixedly connected by self-tapping screws.

[0034] Furthermore, the fasteners include expansion bolts 5, and the side of the crossbeam 11 facing away from the wall is provided with a notch. The side of the crossbeam 11 near the wall is provided with a plurality of slotted holes 112 that pass through the notch along the axial direction, so that the expansion bolts 5 can pass through the slotted holes 112 to fix the crossbeam 11 to the wall.

[0035] By setting notches and grooves on the crossbeam 11, the insertion and tightening of expansion bolts 5 are facilitated, thus improving construction efficiency. The multi-point fixing method formed by multiple expansion bolts 5 improves the wind resistance and seismic performance of the overall structure.

[0036] Furthermore, the horizontal beam 11, vertical beam 12, and side beam 13 are all made of aluminum alloy.

[0037] Because aluminum alloys have low density and high strength, they can reduce the overall structural weight and lower the load requirements on the walls.

[0038] Furthermore, both the inner insulation layer 2 and the outer insulation layer 3 are made of insulating rock wool boards.

[0039] Because of its low thermal conductivity, rock wool can effectively reduce heat transfer. The use of inner and outer double layers of rock wool forms a composite insulation system, which greatly improves the overall thermal performance.

[0040] In some implementations, the external insulation structure also includes a decorative outer protective layer 4, which is disposed on the wall surface of the supporting frame away from the wall and is located outside the external insulation layer 3.

[0041] The decorative outer protective layer 4 can create a decorative effect on the outermost side. Different colors and materials of decorative panels can be selected according to design needs to meet diverse facade requirements. It can also protect the internal insulation layer from the influence of the external environment to a certain extent.

[0042] The implementation principle of a near-zero energy office building exterior wall insulation structure is as follows:

[0043] The horizontal beams 11 are fixed to the outside of the wall using expansion bolts 5 arranged at intervals. The vertical beams 12 are fixed between the corresponding horizontal beams 11 at intervals. The ends of the horizontal beams 11 are sealed using the side beams 13. At the same time, the inner insulation layer 2 is sealed in the adjacent first groove 111, second groove 121, and third groove 132, thereby mechanically limiting the inner insulation layer 2 and preventing it from slipping and falling off. The outer insulation layer 3 is then fixed to the outermost side of the horizontal beams 11, vertical beams 12, and side beams 13, forming a multi-layered insulation and protection effect for the wall.

[0044] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
