Description

Technical Field

[0001] The utility model belongs to the technical field of assembled buildings, and particularly relates to a connection structure of an assembled composite thermal insulation exterior wall panel and a steel beam. Background Art

[0002] With the rapid development of the construction industry, prefabricated composite insulation exterior wall panels have been widely used in various types of buildings due to their high efficiency and environmental protection characteristics. As an important part of the building exterior wall, the connection structure between the prefabricated composite insulation exterior wall panels and the steel beams is crucial. Its stability and convenience directly affect the overall performance and safety of the building. Therefore, the connection structure between the prefabricated composite insulation exterior wall panels and the steel beams is required to make a convenient and reliable connection between the insulation exterior wall panels and the steel beams.

[0003] However, the existing connection structure between the thermal insulation exterior wall panels and the steel beams is not convenient for removing the wall panels from the steel beams during use, which not only makes the exterior wall panels difficult to maintain or replace, thus reducing the service life and overall performance of the building, but also makes it difficult to recycle and reuse the wall panels, resulting in waste. Utility Model Content

[0004] The utility model aims to provide a connection structure of assembled composite thermal insulation exterior wall panels and steel beams. By arranging a detachable connection mechanism, the utility model solves the problem that the existing connection structure of thermal insulation exterior wall panels and steel beams is inconvenient to remove the wall panels from the steel beams during use, which not only makes the exterior wall panels difficult to maintain or replace, thus reducing the service life and overall performance of the building, but also makes it difficult to recycle and reuse the wall panels, resulting in waste.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a connection structure of an assembled composite thermal insulation exterior wall panel and a steel beam, comprising a thermal insulation exterior wall panel, on which two detachable connection mechanisms and two anti-falling mechanisms are arranged;

[0007] A steel beam is provided on the rear side of the thermal insulation exterior wall panel, and the detachable connecting mechanism includes a hollow threaded rod with threads passing through the thermal insulation exterior wall panel and the steel beam, a sliding rod 1 is slidably connected to the inner wall of the front side of the hollow threaded rod, and the front side of the sliding rod 1 slides and extends to the outside of the hollow threaded rod, a support frame is fixedly connected to the inner wall of the hollow threaded rod, and the inner wall of the support frame is slidably connected to the sliding rod 1, and a plurality of hinge blocks 1 are fixedly connected to the rear side of the support frame, and a plurality of hinge rods are hingedly provided on the rear sides of the hinge blocks 1, and a plurality of rectangular through grooves are opened on the hollow threaded rod.

[0008] Furthermore, a plurality of hinge blocks 2 are fixedly connected to the outer wall of the sliding rod 1, and a plurality of hinge blocks 2 are hingedly provided with hollow hinge rods on one side away from each other, and the plurality of hollow hinge rods are respectively matched with a plurality of rectangular through grooves, and the inner walls of the plurality of hollow hinge rods are respectively hinged with the plurality of hinge rods.

[0009] Furthermore, a telescopic rod is fixedly connected to the rear side of the slide rod 1, and the rear side of the telescopic rod is fixedly connected to the hollow threaded rod. A spring is sleeved on the outer wall of the slide rod 1, and the front and rear sides of the spring are fixedly connected to the slide rod 1 and the hollow threaded rod respectively.

[0010] Furthermore, a button is fixedly connected to the front extension portion of the sliding rod 1, and a knob is fixedly connected to the outer wall of the hollow threaded rod.

[0011] Furthermore, the anti-falling mechanism comprises circular sliding grooves provided on the hollow threaded rod and the first sliding rod, and the second sliding rod is slidably connected to the inner walls of the two circular sliding grooves.

[0012] Furthermore, the top of the second slide bar is fixedly connected with a limiting block, and the outer wall of the second slide bar is slidably connected with a hexagonal limiting block.

[0013] Furthermore, the hexagonal limit block and the second slide rod are both provided with rectangular slide grooves, and buckles are provided in the two rectangular slide grooves.

[0014] The utility model has the following beneficial effects:

[0015] 1. By setting a detachable connection mechanism, first align the threaded holes on the thermal insulation exterior wall panel and the steel beam, and then press the button, the button drives the slide bar 1 to move backward, so that the slide bar 1 drives the four hinge blocks 2 to move backward, the four hinge blocks 2 drive the hollow hinge rods to rotate, and at the same time the four hinge rods rotate, so that the four hollow hinge rods are close to each other, and then the four hollow hinge rods are retracted into the hollow threaded rods through the four rectangular through grooves. At this time, the spring and the telescopic rod are squeezed and contracted by the slide bar 1. After the hollow hinge rod is retracted into the hollow threaded rod, the telescopic rod and the spring are compressed to the limit state, and then the hollow threaded rod is screwed into the threaded holes on the thermal insulation exterior wall panel and the steel beam through the knob. After it is rotated to the appropriate position, release the button, and the spring rebounds to drive the telescopic rod and the slide bar 1 to reset. The first slide bar drives the hollow hinged rod and the hinged rod to reset through the second hinged block, that is, the four hollow hinged rods are stretched again, and then the knob is reversed to make the knob move forward with the hollow hinged rod thereon until the front sides of the four hollow hinged rods are in close contact with the rear side of the steel beam, and the rotation of the hollow threaded rod is stopped. At this time, the hollow threaded rod can no longer fall off naturally. When it needs to be taken out, just press the button again to retract the four hollow hinged rods into the thermal insulation outer wall panel, and then the hollow threaded rod can be screwed out, and the thermal insulation outer wall panel can be removed from the steel beam, so that the wall panel can be easily removed when the thermal insulation outer wall panel needs to be maintained or replaced, thereby extending the service life of the building while improving the overall performance of the building, and the wall panel can also be recycled and reused to achieve material recycling;

[0016] 2. By setting up an anti-falling mechanism, when the detachable connecting mechanism connects the thermal insulation exterior wall panel and the steel beam, the circular grooves on the hollow threaded rod and the slide rod one are just aligned, and the slide rod two is inserted to release the limit block to the hollow threaded rod. At this time, the rectangular groove on the limit block is exposed, and the hexagonal limit block is put on the slide rod two, and the two rectangular grooves are aligned, and the buckle is inserted to lock it, so that the slide rod one can no longer move, so that the connection between the assembled composite thermal insulation exterior wall panel and the steel beam can be ensured to be more firmly connected, thereby preventing the slide rod one from sliding due to accidentally touching the button, and avoiding the hollow hinged rod from being accidentally retracted, the hollow threaded rod from rotating, the wall panel from falling off, and injuring nearby people.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
