Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, and in particular to a wall panel connection and fixing device. Background Technology

[0002] In the field of prefabricated building research, performance tests such as the connection structure between wall panels, the connection structure between wall panels and the building envelope insulation system, the airtightness and watertightness testing of wall panels, and the performance monitoring of wall panel and photovoltaic panel combinations are core aspects of ensuring building structural safety, energy efficiency, and functionality. Conducting these tests requires wall panels to meet specific conditions, including the ability to be vertically fixed to simulate actual installation conditions, the ability to move and adjust horizontally to adapt to different test scenarios, and support for various connection methods such as straight horizontal connections or corner horizontal connections, to comprehensively verify the performance of wall panels under different assembly conditions. However, existing research experiments have significant limitations in their implementation. Most experiments use horizontal placement of wall panels in a fixed test site, indirectly replacing vertical testing with theoretical calculations. This fails to accurately reflect the vertical stress and working state of the wall panels in actual buildings. Some experiments rely on scaled-down models for local performance testing, which reduces testing costs and difficulty but cannot reflect the true performance of the overall wall panel and its connection structure. These testing methods are not only inconvenient, but the test conditions also differ significantly from the actual usage conditions of the wall panels, potentially leading to discrepancies between the test results and actual engineering applications, thus affecting the accuracy of tests on the performance of prefabricated building wall panels.

[0029] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0030] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “” used herein may also indicate the inclusion of the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated, unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0031] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0032] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may also be rotated 90 degrees or in other orientations, and the spatial relative descriptors used in the text will be interpreted accordingly.
