Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated building technology, specifically to a connection structure between a prefabricated composite insulated exterior wall panel and a steel beam. Background Technology
[0002] The connection structure design between insulated exterior wall panels and steel beams primarily ensures the stability and safety of the connection between the wall panels and the steel beams, preventing cracks, deformation, or failure during use. This type of connection is commonly used in building exterior wall systems, especially in high-rise or industrial buildings.
[0003] Patent publication number CN222557852U relates to a connection structure between a prefabricated composite insulated exterior wall panel and a steel beam, belonging to the field of prefabricated building technology. This utility model includes an insulated exterior wall panel with two detachable connection mechanisms and two anti-detachment mechanisms. A steel beam is located on the rear side of the insulated exterior wall panel. Each detachable connection mechanism includes a hollow threaded rod threaded through both the insulated exterior wall panel and the steel beam. A sliding rod is slidably connected to the front inner wall of the hollow threaded rod, and the front side of the sliding rod extends slidably beyond the hollow threaded rod. This patent, by providing a detachable connection mechanism, solves the problem of existing connection structures between insulated exterior wall panels and steel beams, which make it difficult to detach the wall panel from the steel beam during use. This not only makes the exterior wall panel difficult to maintain or replace, reducing the building's service life and overall performance, but also makes it difficult to recycle and reuse the wall panel, resulting in waste.
[0004] In the aforementioned patent, by setting a detachable connection mechanism, the problem of the existing connection structure between the insulated exterior wall panel and the steel beam is solved. During use, it is not convenient to remove the wall panel from the steel beam, which not only makes the exterior wall panel difficult to maintain or replace, reducing the service life and overall performance of the building, but also makes it difficult to recycle and reuse the wall panel, resulting in waste. However, during the installation process, due to the size of the insulation board, it may be difficult for workers to align the holes on the surface of the insulation board with the holes on the surface of the steel beam, thus affecting the installation efficiency. Therefore, a prefabricated composite insulated exterior wall panel and steel beam connection structure that is easy to connect is designed. Utility Model Content
[0005] To overcome the above-mentioned defects, this utility model provides a connection structure between a prefabricated composite thermal insulation exterior wall panel and a steel beam, which solves the technical problem in the prior art that the size of the thermal insulation panel may make it difficult for workers to align the holes on the surface of the thermal insulation panel with the holes on the surface of the steel beam, thus affecting the installation efficiency.
[0006] According to one aspect, at least one embodiment of the present invention provides a connection structure between a prefabricated composite thermal insulation exterior wall panel and a steel beam, including a steel beam and a thermal insulation panel, and further including a docking device and a limiting device;
[0007] The docking device includes a pin, a rotating rod is rotatably installed inside the pin, a docking hole one is opened on the surface of the steel beam, and a docking hole two is opened on the surface of the insulation board;

The second connecting rod is rotatably mounted on the end of the first connecting rod away from the first receiving shaft. The second receiving shaft rotatably passes through the end of the second connecting rod away from the first connecting rod. The second fixing block is fixedly mounted on the surface of the pin.
[0010] For example, in a connection structure between a prefabricated composite thermal insulation exterior wall panel and a steel beam provided in at least one embodiment of this utility model, a spiral groove is provided on the surface of the rotating rod, and the sleeve is connected to the rotating rod by a thread.
[0011] Two docking devices are provided, and they are symmetrically distributed at both ends of the rotating rod.
[0012] According to another aspect, at least one embodiment of the present invention also provides a connection structure between a prefabricated composite thermal insulation exterior wall panel and a steel beam. The limiting device includes a sliding plate, a connecting plate, a fixing block three, a connecting rod three, a limiting rod, and a fixing plate. The sliding plate is slidably installed inside the rotating rod. The connecting plate is fixedly installed on the surface of the sliding plate. The fixing block three is fixedly installed above the connecting plate. The connecting rod three is rotatably installed above the fixing block three.

[0015] The beneficial effects of the embodiments of this utility model are as follows:
[0016] In this invention, by setting a gasket, the moving insulation plate allows the pin to be gradually guided to the second docking hole under the action of the gasket and complete the docking.

Detailed Implementation
[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.
[0025] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0030] like Figures 1-4 As shown, it illustrates a connection structure between a prefabricated composite thermal insulation exterior wall panel and a steel beam in one embodiment of the present invention, including a steel beam 101 and a thermal insulation panel 201, as well as a docking device and a limiting device.
[0031] The docking device includes a pin 301, a rotating rod 302 is rotatably installed inside the pin 301, a docking hole 102 is opened on the surface of the steel beam 101, and a docking hole 202 is opened on the surface of the insulation board 201.
[0032] The docking device also includes a gasket 203, which is disposed on the surface of the insulation board 201 to assist the docking of the pin 301. The gasket 203 is configured in a U-shape.
[0033] In some examples, the docking device further includes a sleeve 303, a fixing block 304, a receiving shaft 305, a connecting rod 306, a connecting rod 307, a receiving shaft 308, and a fixing block 309. The sleeve 303 is slidably mounted on the circumferential surface of the rotating rod 302. The fixing block 304 is fixedly mounted on the surface of the rotating rod 302. The receiving shaft 305 rotatably passes through the fixing block 304. The connecting rod 306 is rotatably mounted on the circumferential surface of the receiving shaft 305. The connecting rod 307 is rotatably mounted on the end of the connecting rod 306 away from the receiving shaft 305. The receiving shaft 308 rotatably passes through the end of the connecting rod 307 away from the connecting rod 306. The fixing block 309 is fixedly mounted on the surface of the pin 301.
[0034] The surface of the rotating rod 302 is provided with a spiral groove, and the sleeve 303 is connected to the rotating rod 302 by a thread.
[0035] There are two docking devices, which are symmetrically distributed at both ends of the rotating rod 302.
[0036] For example, such as Figures 1-4 As shown, the gasket 203 is adhered to the second mating hole 202 on the surface of the insulation board 201. Then, the pin 301 is installed inside the first mating hole 102 on the surface of the steel beam 101. The insulation board 201 is then moved to make it fit against the surface of the pin 301. During this process, the movement of the insulation board 201 guides the pin 301 gradually towards the second mating hole 202 under the action of the gasket 203, completing the mating. This effectively improves the mating efficiency between the insulation board 201 and the steel beam 101 and avoids issues related to visibility. The limitations make docking difficult. After docking, the rotating rod 302 is rotated and the sleeve 303 is moved closer to the steel beam 101 and the insulation board 201 through the threaded groove. During this process, the sleeve 303 will drive the receiving shaft 305 and the connecting rod 306 to rotate through the fixing block 304, and gradually make the connecting rod 307 rotate until the steel beam 101 and the insulation board 201 are in contact, thereby completing the fixation of the insulation board 201 and improving the docking efficiency between the insulation board 201 and the steel beam 101.
[0037] like Figures 1-4As shown, this invention illustrates a connection structure between a prefabricated composite thermal insulation exterior wall panel and a steel beam in another embodiment of the present invention. The limiting device includes a sliding plate 401, a connecting plate 402, a fixing block 303, a connecting rod 304, a limiting rod 405, and a fixing plate 406. The sliding plate 401 is slidably installed inside the rotating rod 302. The connecting plate 402 is fixedly installed on the surface of the sliding plate 401. The fixing block 303 is fixedly installed above the connecting plate 402. The connecting rod 304 is rotatably installed above the fixing block 303. The limiting rod 405 is rotatably installed at the end of the connecting rod 304 away from the fixing block 303. The fixing plate 406 is fixedly installed on the inner wall of the rotating rod 302.
[0038] In some examples, the connecting plate 402 slides through the fixed plate 406, and a telescopic spring rod 407 is provided between the fixed plate 406 and the sliding plate 401.
[0039] A limiting groove 408 is formed on the surface of the rotating rod 302, and the limiting rod 405 is slidably connected to the inner wall of the limiting groove 408.
[0040] For example, such as Figures 1-4 As shown, during the docking process, pressing the sliding plate 401 causes the sliding plate 401 to move, which in turn moves the connecting plate 402. The moving connecting plate 402 then moves the fixing block 403, which in turn moves one end of the connecting rod 404. This movement of one end of the connecting rod 404, through the other end, causes the limiting rod 405 to move downwards. The limiting rod 405 moves downwards, disengaging from the limiting groove 408 and releasing its obstruction of the sleeve 303. After docking is completed, the sliding plate 401 resets under the action of the fixing plate 406 and the telescopic spring rod 407, causing the limiting rod 405 to move upwards again to block the sleeve 303. This effectively limits the rotation rod 302, preventing loosening and disengagement during prolonged use, extending the equipment's lifespan, and reducing maintenance costs.
[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
