Description

Technical Field

[0001] This utility model relates to the field of exterior wall insulation and building energy conservation technology, specifically to a wall structure that can fix photovoltaic brackets. Background Technology

[0002] Building energy consumption accounts for about 35% of my country's total energy consumption. In order to achieve my country's overall goal of carbon neutrality and carbon peaking, energy-saving technologies are becoming increasingly important.

[0003] Photovoltaic power generation is a clean energy source that my country has been vigorously promoting in recent years. Utilizing large areas of newly built and renovated walls to install photovoltaic panels for power generation is also a new technology that my country is strongly advocating.

[0004] Meanwhile, new thermal insulation and energy-saving technologies are being vigorously promoted in both new and existing building exterior wall insulation projects. However, my country's current technical measures combining wall insulation and photovoltaic walls are not yet fully developed, and are still being implemented independently, resulting in serious resource waste. Utility Model Content

[0005] This utility model overcomes the shortcomings of existing technologies that are fragmented and provides a thermal insulation technology suitable for both new and existing building walls, while also solving a series of problems related to photovoltaic panel installation.

[0006] To address the aforementioned technological defects and deficiencies, this utility model is achieved through the following technical solution: a wall structure for fixing photovoltaic brackets, wherein a keel is provided on the outer side of the building wall, and a non-removable template is provided on the outer side of the keel, with a certain distance between the non-removable template and the keel to form a grouting cavity, and the non-removable templates are connected by three-way fasteners.

[0007] The aforementioned wall structure for fixing photovoltaic brackets has an insulation layer between the building wall and the keel.

[0008] In the aforementioned wall structure for fixing photovoltaic brackets, the keel is fixed to the building wall by keel anchors.

[0009] The aforementioned wall structure for fixing photovoltaic brackets has an insulation material layer inside the cavities.

[0010] The aforementioned wall structure for fixing photovoltaic brackets has a three-way fastener structure in which the bottom plate and the top plate are symmetrically arranged, the bottom plate and the top plate are connected by two vertical plates, the top plate has an opening in the middle, the bottom plate and the top plate form a non-removable template slot with the outside of the vertical plates, and the two vertical plates form a photovoltaic bracket slot with the opening.

[0011] In the aforementioned wall structure for fixing photovoltaic brackets, a pad is provided between the three-way clip and the keel, and the clip fixing screw passes through the three-way clip, the pad, and the keel for fixing.

[0012] Compared with existing structural forms and construction techniques, the beneficial effects of this utility model are:

[0013] 1. Wide range of applications: It is applicable to both new and existing buildings;

[0014] 2. Multiple functions:

[0015] a) This invention solves the problem that the insulation layer of existing buildings does not meet the current energy-saving standards, namely: the original insulation layer thickness can no longer meet the current building exterior wall energy-saving standards and needs to be thickened. This utility model adds cavity injection or filling of insulation slurry, which increases the thickness of the building insulation layer and meets the requirements of the current national standards.

[0016] b) Solved the problem of insulation layer falling off due to years of disrepair in existing buildings; (Keel 3 reinforces the original insulation layer twice, making the connection between the original insulation layer and the external wall structure layer more solid).

[0017] c) Solves the problem of easy water seepage in building exterior walls: Because the structure of this utility model forms a cavity 9, the cavity can be continuously filled with insulation material or sealing material, so that the building exterior wall forms a sealed structure and eliminates the risk of water seepage.

[0018] d) The application of vertical clips 6, the left and right slots 6-4 fix the formwork without disassembly, and can form a cavity 9. The outer slots 6-5 can fix the photovoltaic bracket, so that the building exterior wall can not only meet the requirements of traditional building energy conservation, but also add new energy technology measures for photovoltaic power generation.

[0019] e) Dual cavity design: The inner cavity can be filled with insulation material, or it can be filled with insulation material first and then filled with insulation material; the outer cavity (the cavity between the photovoltaic panel and the non-removable template) can be conveniently arranged with pipelines, and it also serves as a heat dissipation channel for the photovoltaic panel.

[0020] 3. High safety: The force transmission path of all external loads is clear and unambiguous, namely: photovoltaic panel → photovoltaic bracket → vertical fastener → keel → wall structure layer → building foundation;

[0021] 4. Simple to manufacture: Only one type of non-standard vertical clip 6 is included; all others are standard products.

[0022] 5. Low cost: Existing buildings do not need to remove the original insulation layer, and the new insulation layer does not require secondary decoration. The photovoltaic panels serve as a curtain wall effect.
