[0038] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0039] The following combines Figures 1 to 3 , to describe the embodiments of the present utility model.

[0040] According to an embodiment of the present utility model, on the one hand, a connecting device is provided for connecting a first component to be supported 1 and a second component to be supported 2, including: a first fixing member 3 fixedly connected to the first component to be supported 1, and the first fixing member 3 is provided with a first hollow cavity; a second fixing member 4, one end of which is fixedly connected to the second component to be supported 2, and the other end passes through the first hollow cavity. The second fixing member 4 has a moving state of being movably connected to the first fixing member 3 and a stationary state of being fixedly connected to the first fixing member 3. In the moving state, it is used to adjust the distance and angle between the first fixing member 3 and the second fixing member 4.

[0041] By using the first fixing member 3 and the second fixing member 4 as the connecting device to connect the first component to be supported 1 and the second component to be supported 2, and passing the second fixing member 4 through the first hollow cavity of the first fixing member 3, the distance between the first component to be supported 1 and the second component to be supported 2 can be adjusted by adjusting the depth of the second fixing member 4 passing through the first hollow cavity, and the angle between the first component to be supported 1 and the second component to be supported 2 can be adjusted by adjusting the angle of the second fixing member 4 in the first hollow cavity, thereby improving the installation accuracy and installation quality of the first component to be supported 1 and the second component to be supported 2; and the connecting device has a simple structure, convenient operation and low production cost.

[0042] The first component to be supported 1 in this embodiment is the upper chord of the truss, and the second component to be supported 2 is the roof purlin. As an alternative implementation mode, the first component to be supported 1 can also be a long-span curved grid or a steel beam. As an alternative implementation mode, the first component to be supported 1 and the second component to be supported 2 can also be two other connecting structures that need to be adjusted, and no more restrictions are made here.

[0043] In this embodiment, both the first fixing member 3 and the second fixing member 4 are circular tubes. The first fixing member 3 is welded to the upper chord of the truss, and the second fixing member 4 is welded to the roof purlin. As a variant embodiment, it is also possible that the first fixing member 3 is a circular tube and the second fixing member 4 is a round bar, or that only part of the structure of the first fixing member 3 has a hollow cavity, and no further restrictions are made here.

[0044] As Figure 3 shown, the connecting device in this embodiment includes: a connecting member 5. One end of the connecting member 5 is fixedly connected to the other end of the second fixing member 4, and the other end is inserted into the first hollow cavity. Among them, the connecting member 5 is a cross-rib structure and is welded to the second fixing member 4. By inserting the connecting member 5 into the first hollow cavity, the structural strength of the first fixing member 3 can be improved. As a variant embodiment, the connecting member 5 can also be a round bar, and the cross-sectional dimension of the round bar is adapted to the cross-sectional dimension of the first hollow cavity.

[0045] As Figure 3 shown, the second fixing member 4 is provided with a second hollow cavity. One end of the connecting member 5 is inserted into the second hollow cavity, and the other end is disposed outside the second hollow cavity. By inserting the connecting member 5 into the second hollow cavity, the structural strength of the second fixing member 4 can be improved. As a variant embodiment, it is also possible that the second fixing member 4 is a round bar, the cross-sectional dimension of the connecting member 5 is smaller than the cross-sectional dimension of the second fixing member 4, but is adapted to the cross-sectional dimension of the first hollow cavity, and thus the connecting member 5 can be welded to the other end of the second fixing member 4.

[0046] In this embodiment, the cross-sectional dimensions of the first fixing member 3 and the second fixing member 4 are the same. By setting the dimensions of the first fixing member 3 and the second fixing member 4 to be the same, the overall structural strength and aesthetics of the connecting device can be improved.

[0047] As Figure 2 shown, the connecting device in this embodiment includes: a fastening member 6, which is provided with a third hollow cavity. Both the first fixing member 3 and the second fixing member 4 are inserted into the third hollow cavity. Among them, the fastening member 6 adopts a steel plate structure, and the cross-section is circular. The size of the third hollow cavity is adapted to the cross-sectional dimensions of the outer side walls of the first fixing member 3 and the second fixing member 4. By restricting the first fixing member 3 and the second fixing member 4 within the third hollow cavity, it can prevent the first fixing member 3 and the second fixing member 4 from tilting during use, resulting in a reduction in structural stability and causing danger during use.

[0048] As Figure 3As shown, the fastening member 6 is fixedly connected to the first fixing member 3 and the second fixing member 4. Specifically, the fastening member 6 is welded to the first fixing member 3 and the second fixing member 4. By fixedly connecting the fastening member 6 to the first fixing member 3 and the second fixing member 4 simultaneously, the connection tightness between the first fixing member 3 and the second fixing member 4 can be improved, thereby enhancing the integrity of the connection device.

[0049] As Figure 3 shown, the fastening member 6 in this embodiment is jointly spliced by two connecting structures. Among them, the cross-sections of the two connecting structures are both semi-circular. By splicing the fastening member 6 from two connecting structures, it is convenient to connect the fastening member 6 to the first fixing member 3 and the second fixing member 4. As a variable implementation manner, it can also be that the fastening member 6 is jointly spliced by three or four connecting structures, or the fastening member 6 is a sleeve structure. Before inserting the connecting member 5 into the first hollow cavity, the sleeve structure is sleeved on the outer side of the first fixing member 3.

[0050] According to an embodiment of the present invention, on the other hand, a support system is also provided, including: a truss upper chord; a roof purlin spaced from the truss upper chord; and the above-mentioned connecting device for connecting the truss upper chord and the roof purlin.

[0051] As Figure 1 shown, the connecting device in this embodiment includes: a support member 7, fixedly connected to the second fixing member 4 on one side and fixedly connected to the roof purlin on the other side. Specifically, as Figure 3 shown, a clamping groove is provided on the other side of the support member 7, and the roof purlin is fixed in the clamping groove. Further, the support member 7 includes a circular plate structure, and two vertical plates are spaced on the other side of the circular plate structure, and the roof purlin is fixed between the two vertical plates. By providing the support member 7, the contact area between the second fixing member 4 and the roof purlin can be increased, thereby improving the connection stability. As a variable implementation manner, it can also be that a groove is provided on the other side of the disc structure for clamping the roof purlin.

[0052] When the connecting device in this embodiment is in use, first weld the first fixing member 3 to the truss upper chord, weld one side of the support member 7 to the second fixing member 4, and weld the other side to the roof purlin; weld one end of the cross rib structure to the second hollow cavity of the second fixing member 4, and pass the other end through the first hollow cavity of the first fixing member 3, and rotate the second fixing member 4 to adjust the relative positions of the roof purlin and the truss; after the adjustment is completed, weld the other end of the cross rib structure to the first fixing member 3; finally, weld the fastening member 6 to the outer sides of the first fixing member 3 and the second fixing member 4.

[0053] Although embodiments of the present utility model have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present utility model, and such modifications and variations fall within the scope defined by the appended claims.
