DETAILED DESCRIPTION

[0019] like Figure 1-Figure 4 As shown, a 12-fold profile welding frame proposed in this embodiment includes four vertically distributed vertical beams 1, four horizontally distributed horizontal beams a2, four horizontally distributed horizontal beams b3 and eight connecting heads 4.

[0020] The vertical beam 1, the horizontal beam a2 and the horizontal beam b3 are perpendicular to each other, and the four vertical beams 1, the four horizontal beams a2 and the four horizontal beams b3 are distributed according to the positions of the twelve sides of the rectangular parallelepiped.

[0021] The eight connectors 4 are respectively distributed at the eight corners of the cuboid, and each connector 4 is welded to an adjacent vertical beam 1, a horizontal beam a2 and a horizontal beam b3.

[0022] The cross-sectional profiles of the vertical beam 1, the horizontal beam a2 and the horizontal beam b3 are the same, and the main difference is the length. Of course, they can also be designed to be equal in length, with two of the beams being equal in length, or with all three beams being equal in length, depending on the size of the overall frame to be designed.

[0023] The vertical beam 1, the horizontal beam a2 and the horizontal beam b3 are all twelve-fold profile structures, and all have an inner clamping surface 11 located on the inner side and an outer clamping surface 12 located on the outer side. The thickness of the twelve-fold profile structure is 2.5 mm, and the twelve-fold profile is rolled by a rolling line.

[0024] The connector 4 has three mutually perpendicular abutting surfaces 401 , and adjacent ends of the vertical beam 1 , the horizontal beam a2 and the horizontal beam b3 abut against the three abutting surfaces 401 of the same connector 4 , respectively. Then, eight connectors 4 can be used to firmly connect the twelve beams.

[0025] The abutting surface 401 is provided with a clamping platform a41, a clamping platform b42 and a clamping platform c43 clamped with the inner clamping surface 11, and a clamping platform d44 clamped with the outer clamping surface 12. The inner clamping surface 11 of the profile is clamped on the outer side of the clamping platform a41, the clamping platform b42 and the clamping platform c43, and the outer clamping surface 12 is clamped on the inner side of the clamping platform d44. The profile is first clamped with the connector 4 and then welded, and the overall frame structure is firmly connected.

[0026] The ends of the vertical beam 1, the horizontal beam a2 and the horizontal beam b3 are all provided with a plurality of slots 13, and the abutting surface 401 is provided with a clamping platform e45 adapted to the slots 13. By providing the slots 13 and the clamping platform e45, the stability of the connection between the beam and the connector 4 can be further improved.

[0027] In order to further improve the smoothness of profile installation, bevels are set at the outer ends of the clamping platform a41, the clamping platform b42 and the clamping platform c43 to guide the installation of the vertical beam 1, the horizontal beam a2 and the horizontal beam b3. The clamping platform d44 is a semi-cylindrical boss structure, which is convenient for clamping into the clamping slot 13.

[0028] This embodiment can improve the structural stability, reliability and earthquake resistance. During assembly, the vertical beam 1, the horizontal beam a2 and the horizontal beam b3 are respectively inserted into the clamping platform a41, the clamping platform b42, the clamping platform c43, the clamping platform d44 and the clamping platform e45 of the connector 4, and the ends are abutted against the abutting surface 401, first clamped and then welded, which can effectively improve the connection reliability and structural strength of the overall frame structure.

[0029] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
