[0037] like Figure 1-2 As shown, a detachable roof beam-column node structure is proposed, which is located at the overlap of the roof beam 1 and the bottom support column 2. The node structure includes: a first ear plate 3 arranged at the bottom end of the roof beam 1; a second ear plate 4 arranged on the side of the support column 2 and overlapping with the first ear plate 3, which can be arranged by welding; and a limit pin 7 arranged through the first ear plate 3 and the second ear plate 4. By removing and installing the limit pin 7, the installation and separation of the first ear plate 3 and the second ear plate 4 are realized, so that the roof can be conveniently lifted and opened, and the equipment can be conveniently lifted and transported outdoors.

[0038] Among them, Figure 2 As shown, the first ear plate 3 and the second ear plate 4 are both arranged in parallel, and the first ear plate 3 is inserted in the reserved gap between the adjacent second ear plates 4; in this specific embodiment, the second ear plates 4 have 3 arranged in parallel, and the first ear plates 3 have 2 arranged in parallel, and the two first ear plates 3 are respectively inserted in the gaps between the adjacent second ear plates 4 of the three second ear plates 4, wherein the contact surface of the second ear plate 4 is larger than the contact surface of the first ear plate 3. In other embodiments, the number of the first ear plates 3 can also be greater than the number of the second ear plates 4, so that multiple second ear plates 4 are inserted in the gaps between the adjacent first ear plates 3; and the adjacent first ear plates 3 and second ear plates 4 are arranged in close contact. The arrangement of multiple first ear plates 3 and second ear plates 4 makes the node structure more stable and not easy to shake after installation. In order to further ensure the stability of the node structure, a stiffening rib 13 located at the bottom end of the second ear plate 4 is also arranged on the side of the support column 2.

[0039] Furthermore, in order to ensure the rationality of the force, the second ear plate 4 located in the middle is located in the same plane as the middle connecting plate of the support column 2; the other second ear plates 4 are symmetrically arranged along the second ear plate 4 in the middle.

[0040] As well as Figure 2 and Figure 3As shown, in the overlapping area of ​​the first ear plate 3 and the second ear plate 4, the first ear plate 3 is provided with a first pin hole 5, the second ear plate 4 is provided with a second pin hole 6 corresponding to the position of the first pin hole 5, and the limiting pin 7 is provided through the first pin hole 5 and the second pin hole 6.

[0041] like Figure 4 As shown, the limiting pin 7 includes a rod 9 that passes through the first pin hole 5 and the second pin hole 6, one end of the rod 9 has a head 8, and the other end is screwed with a limiting bolt 10, and the first ear plate 3 and the second ear plate 4 are located between the head 8 and the limiting bolt 10; the limiting bolt 10 can specifically include a screw that passes through the rod 9 and a nut that is screwed at the end, and the rod 9 can have a groove for the limiting bolt 10 to move horizontally, so as to facilitate the clamping of the first ear plate 3 and the second ear plate 4. In order to ensure the stability of the bolt connection, the rod 9 is also sleeved with a first washer 11 and a second washer 12 that fit with the head 8 and the limiting bolt 10 respectively, and the first ear plate 3 and the second ear plate 4 are fitted between the first washer 11 and the second washer 12.

[0042] In actual use, when installing the roof, align the first pin hole 5 of the first ear plate 3 and the second pin hole 6 of the second ear plate 4, pass the rod 9 of the limit pin 7 through the first pin hole 5 and the second pin hole 6, and tighten the limit bolt 10 at the end, so that the roof beam 1 and the support column 2 can be connected. When removing the roof, unscrew the limit bolt 10 at the end of the limit pin 7, pull the limit pin 7 out of the first pin hole 5 and the second pin hole 6, lift the roof, and then the roof and the support column 2 can be disengaged to realize the removal of the roof. During the implementation of this solution, the wall is not damaged, and it is more convenient and quick to install the roof.
