The arrangement of the first connecting post 164 and the second connecting post 165 enables the plurality of secondary purlins 160 to be connected to each other, and the number of connections can be selected according to actual needs. And the purlin 10 is more flexible and changeable in the process of assembling the purlin unit 100, and the above-mentioned connection mode is simple and convenient, and the installation efficiency is high. The fixed disk 11 installed simultaneously can play a role in strengthening positioning, can well realize the overall fixation and the positioning of any polygonal axial center position, and prevents the structure of the house purlin 10 from being changed.
As shown in fig. 1 and 2, the connection member 110 includes: a main purlin connecting part 111 for connecting with the main purlin 150 and a secondary purlin connecting part 112 for connecting with the secondary purlin 160, wherein the main purlin connecting part 111 is hollow, and the hollow part is a main purlin connecting groove 113; the secondary purlin connecting portion 112 includes a first connecting plate 112a and a second connecting plate 112b, one end of the first connecting plate 112a, one end of the second connecting plate 112b is connected with a side wall of the primary purlin connecting portion 111, the first connecting plate 112a and the second connecting plate 112b are oppositely arranged, and a first clamping cavity 114 capable of being clamped into at least a part of the secondary purlin 160 is formed between the first connecting plate 112a and the second connecting plate 112 b.
The main purlin 150 is hollow, an installation protrusion (not shown) is arranged on the inner wall of the main purlin 150 corresponding to the hollow 151, the installation protrusion is inserted into the main purlin connecting groove 113, the secondary purlin 160 comprises a third connecting plate 161, the third connecting plate 161 is clamped in the first clamping cavity 114, and the third connecting plate 161 is connected with the first connecting plate 112a and the second connecting plate 112 b. As shown in fig. 3, in this embodiment, the mounting bosses are a plurality of stainless steel pins 181 inserted through the side walls of the main purlin 150 into the main purlin attachment slots 113.
The connection member 110 has the advantages that the connection and installation of the main purlin 150 and the secondary purlin 160 are more convenient due to the specific structure arrangement of the main purlin connection part 111 and the secondary purlin connection part 112, the assembly is more efficient, the installation time of the main purlin 150 and the secondary purlin 160 can be effectively saved, and the installation efficiency is improved.
The main purlin 150 and the sub purlin 160 are connected by the connecting member 110, so that the assembly of the purlin unit 100 is convenient and efficient.
Further, the main purlin connecting portion 111 has an abutment surface 115 that contacts the main purlin 150, the abutment surface 115 is a flat plane, and the main purlin connecting groove 113 is opened in the abutment surface 115 and extends to the other surface of the main purlin connecting portion 111 opposite to the abutment surface 115. Because the inner wall corresponding to the hollow portion 151 of the main purlin 150 is generally a flat plane, when the main purlin connecting portion 111 is connected with the main purlin 150, the abutting surface 115 is a flat plane, so that the main purlin connecting portion 111 can be completely abutted with the inner wall of the main purlin 150, and the connection stability is better.
Further, in order to make the connection stability between the main purlin 150 and the main purlin connecting portion 111 better, the mounting protrusion does not move in the main purlin connecting groove 113 with respect to the main purlin connecting groove 113, and the main purlin connecting groove 113 has at least one corner, and the shape of the mounting protrusion matches the main purlin connecting groove 113.

Since the roof is generally inclined downwardly in shape, and the corresponding main purlin 150 is also inclined downwardly when installed as the house purlin 10, the abutment surface 115 is also inclined downwardly in order to correspond to the main purlin 150 and to make the connection more stable.
Further, screw holes are provided on both the first connection plate 112a and the second connection plate 112 b. The screw hole is a first through hole 117, a second through hole (not shown) is provided in the third connecting plate 161, and the first and second connecting plates 112a and 112b and the third connecting plate 161 are connected by passing through the first and second through holes 117 and 171.
Further, the secondary purlin 160 further includes a fourth connecting plate 162, a second clamping cavity 166 is formed between the fourth connecting plate 162 and the third connecting plate 161, and the first connecting plate 112a is clamped in the second clamping cavity 166. The fourth connection plate 162 is also provided with a second through hole, and when the first bolt 171 connects the secondary purlin 160 and the secondary purlin connection portion 112, the first bolt 171 passes through the first through hole 117 on the second connection plate 112b, the second through hole on the third connection plate 161, the first through hole 117 on the first connection plate 112a, and the second through hole on the fourth connection plate 162 in this order, thereby realizing connection.
Further, a convex engaging strip 118 is disposed on a surface of the first connecting plate 112a facing the second connecting plate 112 b. The third connecting plate 161 has a locking protrusion engaging groove 163 formed on a side facing the second connecting plate 112b, and the locking protrusion 118 is disposed in the locking protrusion engaging groove 163. The above arrangement makes the connection of the secondary purlin 160 to the connector 110 more secure.
