[0002] In the process of connecting solar photovoltaic modules, C-beams and U-beams are used for connection and installation. However, the traditional method of connecting C-beams and U-beams by right-angle splicing and welding or bolt fastening results in poor stability of the C-beams and U-beams. Some systems use connectors as the middle part to connect the two, but the production efficiency of general connectors is low, the installation is more complicated, and the fit with C-beams and U-beams is not tight, resulting in low load-bearing capacity and low overall structural stability after connection. Utility Model Content

[0003] The purpose of this utility model is to provide an installation connection structure for C-shaped beams and U-shaped beams to solve the above problems, which allows for rapid installation, tight fit, and high strength of the connection installation structure.

The U-shaped beam has an outwardly extending flange on its side. The C-shaped beam and the U-shaped beam are perpendicularly connected. One side of the connector is a first connecting part, and the other side is a second connecting part, which are used to connect the U-shaped beam and the C-shaped beam respectively. The C-shaped beam and the U-shaped beam are connected and fixed by fasteners. The upper part of the first connecting part is provided with a flange groove that mates with the flange, and the lower part is a connecting part that abuts against the U-shaped beam. The connecting part has a bolt mounting hole in the middle. The second connecting part is inserted into the C-shaped beam for connection. The upper and lower sides of the second connecting part are recessed slopes to facilitate insertion into the C-shaped beam. The second connecting part has a screw fixing hole in the middle.

[0005] Furthermore, in the aforementioned installation connection structure of C-shaped beams and U-shaped beams, the U-shaped beams have through holes on both sides, and the through holes correspond to and cooperate with bolt mounting holes.

[0006] Furthermore, in the aforementioned installation and connection structure of C-shaped beams and U-shaped beams, the two side plates at the open end of the C-shaped beam have an inward bending design.

[0007] Furthermore, in the aforementioned installation and connection structure of C-shaped beams and U-shaped beams, the C-shaped beam has through screw holes at both ends of its side surface. The through screw holes correspond to and cooperate with the screw fixing holes, and are fastened together by self-tapping screws.

[0008] Furthermore, in the aforementioned installation and connection structure of C-shaped beams and U-shaped beams, the screw through holes are equidistantly arranged at both ends of the side of the C-shaped beam.

[0009] Furthermore, in the aforementioned installation connection structure for C-shaped beams and U-shaped beams, the connecting member has a hollow structure in the middle.

[0010] Furthermore, in the above-mentioned installation connection structure of C-shaped beam and U-shaped beam, the through hole and the bolt mounting hole are fixed by bolts. The bolt is inserted into the through hole and a washer is provided between them. The bolt passes through the bolt mounting hole and a flange nut is provided inside the bolt mounting hole to tighten and fix the bolt.

[0011] Furthermore, in the aforementioned installation connection structure for C-shaped beams and U-shaped beams, the outer side of the screw fixing holes has a clearance groove design.

[0012] Furthermore, in the aforementioned installation and connection structure of C-shaped beams and U-shaped beams, the U-shaped beams, C-shaped beams, and C-shaped beams all have rounded corners at their external edges.

[0013] Furthermore, in the aforementioned installation connection structure of C-shaped beams and U-shaped beams, the sunken inclined surface has chamfered designs on both sides.

[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects: The installation connection structure of C-shaped beams and U-shaped beams described in this utility model uses connectors that fit with U-shaped beams and C-shaped beams for fixed connection, which is convenient and quick to install. The design of the first connecting part and the second connecting part of the connector corresponds to the U-shaped beam and the C-shaped beam respectively. The flange groove cooperates with the flange part, and the sunken slope facilitates the insertion into the C-shaped beam. The contour design makes the installation fit tighter and improves the stability of the connection structure. By matching the holes, the installation position can be quickly determined, which is convenient for operators to carry out construction. The connector is made of aluminum extrusion molding, and then cut into several connectors. Finally, it is chamfered and cut, which is convenient and efficient to produce, has good mechanical properties, and improves the connection strength. Attached Figure Description
