Further, the inner wall of the corresponding main purlin link slot 113 of main purlin interconnecting piece 111 is provided at least one and connect with main purlin
The parallel mounting fastener 116 of 113 depth direction of slot.Accordingly, when be arranged in main purlin link slot 113 at least one mounting fastener
When 116, the shape for the installation protrusion that main purlin 150 is arranged matches with fastener 116 is spliced, in the present embodiment i.e. stainless steel pin
The connection of main purlin 150 and main purlin interconnecting piece 111 is realized in 181 insertion mounting fasteners 116.
Further, using the depth direction of main purlin link slot 113 as vertical direction, bearing surface 115 is connected further away from secondary purlin
Portion 112 more tilts down, and the first connecting plate 112a and the second connecting plate 112b all have and be in conplane with bearing surface 115
End face.Due to when the shape on roof is general diagonally downward, corresponding main purlin 150 when being mounted to room purlin, main purlin 150 also when tilt
Down-set, in order to corresponding with main purlin 150, so that connection is more stable, therefore bearing surface 115 is also to tilt down.
Further, mounting hole is provided on the first connecting plate 112a and the second connecting plate 112b.The mounting hole is the
One mounting hole 117 is provided with the second mounting hole (figure is not marked), the connection of the first connecting plate 112a and second on third connecting plate 161
Plate 112b passes through the first mounting hole 117 and the completion connection of the second mounting hole by bolt 170 with third connecting plate 161.
Further, secondary purlin 160 further includes the 4th connecting plate 162, between the 4th connecting plate 162 and third connecting plate 161
The second clamping chamber 166 is formed, the first connecting plate 112a is arranged in the second clamping chamber 166.It is also equipped on 4th connecting plate 162
Second mounting hole, when bolt 170 connects secondary purlin 160 and time purlin interconnecting piece 112, bolt 170 sequentially passes through the second connecting plate
The first mounting hole 117 on 112b, the second mounting hole on third connecting plate 161, the first installation on the first connecting plate 112a
The second mounting hole on hole 117, the 4th connecting plate 162 realizes connection.
Further, the first connecting plate 112a is provided with card convex item 118 towards the second connecting plate 112b on one side.Third connects
The side of fishplate bar 161 towards the second connecting plate 112b are provided with card convex mating groove 163, and card convex item 118 is set to card convex item and matches
It closes in slot 163.Above-mentioned setting is so that the connection of the connector 110 of secondary purlin 160 and main purlin and time purlin is more firm.
The opposite end of secondary purlin 160 is respectively arranged with the first connecting column 164 and the second connecting column 165, the first connecting column
164 is parallel with the second connecting column 165, and the first connecting column 164 and the second connecting column 165 are in the plane parallel with its length direction
Projection without coincidence, the first connecting column 164 is arranged alternately with the second connecting column 165, and the first connecting column 164 is set along its length
It is equipped with the first connection through-hole 167, the second connecting column 165 is provided with the second connection through-hole 168 along its length.
The first connecting column 164 and the second connecting column 165 of secondary 160 both ends of purlin setting, so that multiple 160 phases of secondary purlin interconnect
The connection for realizing multiple room purlin units 100 is connect to constitute complete room purlin.Multiple secondary purlins 160 are mutually connected to incite somebody to action
Multiple secondary purlins 160 splice cyclization, connect in through-hole 167 and the second connection through-hole 168 to the first of two neighboring secondary purlin and insert simultaneously
Enter to connect the connection that bolt realizes multiple secondary purlins 160.Therefore, the setting of the first connecting column 164 and the second connecting column 165 is so that more
A secondary purlin 160 can be connected with each other, and can select the number of connection according to actual needs.So that room purlin is by room purlin unit
It is more flexible changeable during 100 assembly.
In order to guarantee the stability of connection, fixed disk is set by multiple secondary purlins 160 in the two sides up and down of multiple secondary purlins 160
Position and shape be fixed.
In conclusion the connector of main purlin provided by the utility model and time purlin, since main purlin interconnecting piece is connected with time purlin
The specific structure in portion is arranged, and so that winner's purlin is connected by main purlin with the connector of time purlin with time purlin, and be linked and packed
