Description

Technical Field

[0001] This utility model relates to the field of profile connection technology, and more specifically, to a main beam profile connection structure. Background Technology

[0002] In the structure of a sunroom, the connection between the main beam and the front beam is a key link to ensure the overall structural stability and load-bearing capacity. Traditional methods for connecting the main beam and the front beam often involve welding, bolting, or direct riveting. While these methods can meet the connection requirements to a certain extent, they each have their own limitations.

[0003] While welded connections offer high strength, they are complex to operate and require sophisticated welding techniques. Furthermore, the thermal stress generated during welding can easily lead to material deformation, affecting connection accuracy and overall structural stability. Although bolted connections facilitate disassembly and reinstallation, bolts are prone to loosening under long-term stress or vibration, resulting in loose connections and compromising structural safety. Direct riveting often requires a large assembly space at the connection point, and stress concentration at the riveted connection point can easily become a weak link in the structure. Therefore, to address the aforementioned technical problems, a main beam profile connection structure is proposed here. Utility Model Content

[0004] The purpose of this utility model is to provide a main beam profile connection structure. By fitting the limiting member into the slot, the main beam can be embedded in the front beam to complete the mortise and tenon connection. In addition, the plate structure composed of the mounting plate and the top connecting plate realizes the stable assembly between the main beam and the front beam, which greatly improves the stability of the installation structure.

[0005] This utility model is achieved through the following technical solution:

[0006] A main beam profile connection structure includes a front beam and a main beam. The front beam has a first slot and a second slot on one side. The main beam is externally fixedly connected to a limiting member, and the bottom of the limiting member protrudes from the lower side of the main beam. The limiting member matches the first slot and the second slot. The main beam is externally fixedly connected to an overlapping strip, and the overlapping strip fits tightly with the main beam. A fastening mechanism is installed between the main beam and the front beam.

[0007] Preferably, the second slot is located at both ends of the front beam, and the first slot is located between the two sets of the second slots.

[0008] Preferably, the main beam is matched with the first slot and the second slot.

[0009] Preferably, the fastening mechanism includes a mounting plate, a top connecting plate, and a first screw. The mounting plate is fixedly connected to the main beam, and the top connecting plate is fixedly connected to the front beam.

[0010] Preferably, multiple sets of the first screws are riveted between the mounting plate and the main beam, and between the top connecting plate and the mounting plate.

[0011] Preferably, the bottom of the main beam is fixedly connected to a buckle groove, and a buckle plate is fixedly connected to the inner side of the buckle groove.

[0012] Preferably, a second screw is riveted between the bottom of the groove and the main beam.

[0013] The technical solution of this utility model has at least the following beneficial effects:

[0014] This utility model proposes a main beam profile connection structure. When assembling and connecting the main beam and the front beam, a limiting member at one end of the main beam can be inserted into the first slot. At this time, under the limiting sliding action of the limiting member in the first slot, one end of the front beam can slide into the first slot, so that the main beam and the front beam can be connected in close contact. It also controls the overlap strip installed on the top of the main beam and the top of the front beam to be fully in contact. Then, the plate-like structure composed of the mounting plate and the top connecting plate is riveted with the first screw, so that the stable assembly between the main beam and the front beam can be achieved, which greatly improves the stability and installation convenience of the installation structure.
