Description

Technical Field

[0001] This utility model relates to a concealed connection node for prefabricated external wall panels, belonging to the field of prefabricated building technology. Background Technology

[0002] Precast exterior wall panels refer to sound-insulating and heat-insulating boards made of certain materials that are fixed to the exterior walls of buildings on the basis of concrete or brick-wood structures, forming an airtight sound-insulating layer that enhances the building structure and provides sound insulation and heat preservation.

[0003] Currently, the main connection methods between prefabricated exterior wall panels and building structural beams are the hanging type and the pre-embedded connection steel bar and poured concrete type. The hanging type refers to the connection through metal hangers pre-installed on the wall panels and the main structure.

[0004] In the existing technology, the connection node structure of the hanging-type external wall panel will be exposed above the building structural beam or inside the external wall panel after installation, which will affect the interior layout and is not aesthetically pleasing.

[0005] In existing technologies, the top of the lower wall panel and the bottom of the upper wall panel need to be connected to the building structural beams using different brackets, which results in a large number of installation parts, difficulty in accurate installation, and low installation efficiency.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] This utility model addresses the shortcomings of the prior art by providing a concealed connection node for prefabricated exterior wall panels, which enables concealed installation of the hangers, making the installation process convenient and efficient, and does not affect the interior layout after installation.

[0008] To solve the above technical problems, the present invention adopts the following technical solution:

[0009] The prefabricated exterior wall panel uses a concealed connection node, including an exterior wall panel. The exterior wall panel has a rib on its inner side, and a fixing seat is installed on the inner side of the exterior wall panel, which is symmetrically arranged in the vertical direction. The fixing seat is fixedly installed on the outer side of the rib. The fixing seat is connected to the embedded part at the top of the structural beam through a connector. The connector is a T-shaped structure, including a vertically fixed and connected cubic tube and a horizontal tube. Both ends of the cubic tube in the vertical direction are located in the first mounting cavity of the fixing seat, and the horizontal tube is located in the second mounting cavity of the embedded part.

[0010] Furthermore, an insulation layer is filled between the ribs.

[0011] Furthermore, the fixing base includes two side plates arranged side by side, the top ends of the two side plates are fixedly connected to the horizontal plate body, and the horizontal plate body is fixedly connected to the plate rib.

[0012] Furthermore, a first mounting cavity for installing connectors is provided between the two side plates, and a first pin hole is provided on the two side plates, with the center line of the first pin hole passing through the first mounting cavity.

[0013] Furthermore, the cubic tube has a second pin hole corresponding to the first pin hole, and the center line of the second pin hole is set in the horizontal direction.

[0014] Furthermore, the embedded part is located at the angle between the top and side ends of the structural beam, with the upper end of the embedded part flush with the top surface of the structural beam and the side end of the embedded part flush with the side end surface of the structural beam.

[0015] Furthermore, the embedded part has a second mounting cavity for installing the connector. The second mounting cavity has a square structure, and a screw rod arranged vertically is fixed inside the second mounting cavity. The lower part of the screw rod is located inside the structural beam, and the upper part of the screw rod is located inside the second mounting cavity.

[0016] Furthermore, the horizontal square tube has a through hole for the longitudinal insertion of the screw, which is then fixed by a nut after passing through the through hole.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0018] The inner side of the external wall panel is equipped with a fixing seat symmetrically arranged in the vertical direction. The fixing seat is connected to the embedded part at the top of the structural beam through a connector. The connector is installed between the upper and lower external wall panels, fixing the top of the lower external wall panel while supporting the bottom of the upper external wall panel. The installation process is convenient and efficient.

[0019] The nodes in this invention can be installed in a concealed manner, so that they will not affect the interior layout after installation and are aesthetically pleasing.
