Description

Technical Field

[0001] The utility model relates to the technical field of shed frames, in particular to a non-welded single-branch top support device. Background Art

[0002] In the construction of shed frames, single-branch tops are often used as support columns, and then the bottom plate at the top of the single-branch top is fixedly connected to the load-bearing plate. At present, the bottom plates at the tops of single-branch tops on the market are all connected to the tops of single-branch tops by welding. As a result, during the welding and heating process of the bottom plate and the single-branch top, the material properties change, thereby reducing the load-bearing capacity of the single-branch top. In addition, during the installation process, it is often necessary to adjust the heights of individual single-branch tops to meet the requirements of the site. In order to keep the load-bearing plate in a horizontal state, currently, construction workers need to repeatedly adjust the height by visual inspection or using a ruler until the two single-branch tops are adjusted to the same height, which is cumbersome and time-consuming.

Upper buckle pieces detachably connected to the outer tube are arranged at both ends of the first crossbar and the second crossbar.

[0014] Preferably, a clamping ring for clamping the upper buckle piece is arranged on the outer tube at the corresponding position of the upper buckle piece.

Pass the screw 133 through the installation screw hole 132 of the bottom plate 13 and abut against the outer tube 12 and tighten it

[0035] A scale 111 is provided on the circumferential surface of the inner tube 11. The scale 111 is engraved on the circumferential surface of the inner tube 11 by a pneumatic engraving process. The scales 111 of the two inner tubes 11 are of the same height, and the graduations of the scale 111 increase from bottom to top, which is convenient for construction workers to bend down and adjust the height of the outer tube 12 from bottom to top.

[0036] A fixing member 121 for adjusting the position of the outer tube 12 is provided at the bottom of the outer tube 12. The fixing member 121 is of a snap type, and its structure is a prior art and will not be elaborated here.

The end of the fixing member 121 facing the inner tube 11 is a horizontal plane, which is convenient for aligning with the scale 111 on the inner tube 11.

[0037] Both ends of the upper crossbar assembly 2 are detachably installed between the two outer tubes 12. Specifically, the upper crossbar assembly 2 includes a first crossbar 21 and a second crossbar 22 arranged in parallel, and both the first crossbar 21 and the second crossbar 22 are perpendicular to the two outer tubes 12. Two vertical rods 23 and two diagonal rods 24 are provided between the first crossbar 21 and the second crossbar 22, and the two diagonal rods 24 are distributed in an "eight" shape. The diagonal rods 24 can prevent the upper crossbar assembly 2 from deforming.

By pulling up the movable pin 251, the upper snap member 25 can be detached from the snap ring on the outer tube 12.

[0038] Both ends of the described lower crossbar assembly 3 are detachably installed between two inner tubes 11 through adjustable support sleeves 4, and the adjustable support sleeves 4 are movably sleeved on the inner tubes 11. The lower crossbar assembly 3 includes a lower crossbar 31 and lower buckle members 32 provided at both ends of the lower crossbar 31. The design of the lower buckle members 32 is the same as that of the upper buckle members 25. The adjustable support sleeve 4 includes an annular sleeve 41 movably connected to the inner tube 11, and an internal thread 42 threadedly connected to the surface of the inner tube 11 is provided on the inner side surface of the annular sleeve 41. When the adjustable support sleeve 4 is rotated, the adjustable support sleeve 4 can move up and down along the inner tube 11. A plurality of card interfaces 43 for the lower buckle members 32 to be snapped into are provided on the circumferential side surface of the annular sleeve 41.
