Description

Technical Field

[0001] The utility model belongs to the technical field of greenhouses, in particular to an installation structure between a column and a truss of a greenhouse. Background Art

[0002] At present, agricultural greenhouses mostly use steel structures, which usually include multiple vertical columns and trusses erected on the columns. Agricultural greenhouses with this structure are not only low-cost and quick to build, but also have a wide range of applications and can meet the needs of early spring and late autumn production of crops.

[0003] As the instruction manual Figure 1 As shown, the mounting structure between the column (1) and the truss (2) in the prior art is usually to connect the support bar (201) at the end of the truss (2) through a fastener (3). Although this connection structure is simple, after long-term use, if the connection strength between the upper and lower chords of the truss (2) and the support bar (201) deteriorates, the upper and lower chords of the truss (2) and the support bar (201) may be separated, thereby causing the truss (2) to fall off from the column (1), thereby affecting the structural strength of the greenhouse. Therefore, it is urgent to study a mounting structure between the column and the truss of the greenhouse to solve the above problem. Utility Model Content

[0008] As a preferred technical solution of the utility model, a second convex rib is fixed to the lower surface of the limiting protrusion; and one side edge of the second convex rib is fixed to the vertical section of the positioning frame.

[0009] As a preferred technical solution of the utility model, the two load-bearing flanges are both in a "┐"-shaped structure; the upper surfaces of the horizontal sections of the two load-bearing flanges are in contact with the lower surface of the lower chord of the truss; second accommodating holes are provided on the opposite sides of the vertical sections of the two load-bearing flanges; the two second accommodating holes are connected by a second bolt member.
