DETAILED DESCRIPTION

[0040] The following will be combined with the specific embodiments of the present invention to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] like Figure 1-6 As shown, a truss support structure of the present invention includes two brackets 1, a truss 2 and a support frame 3.

[0042] The bracket 1 is used to support other structural members, the trusses 2 , and the two brackets 1 are arranged in parallel and at intervals.

[0043] The truss 2 includes a lower truss beam 21, a web member 22 and an upper truss beam 23. The lower truss beam 21 is fixedly arranged on one of the brackets 1; the web member 22 is fixedly arranged on the top side of the lower truss beam 21; the upper truss beam 23 is fixedly arranged on the top side of the web member 22; Figure 6 As shown, the truss system includes two groups of lower trusses 21, web members 22 and upper trusses 23, and the truss 2 also includes a parallel connecting rod 24. After the two groups of lower trusses 21, web members 22 and upper trusses 23 are assembled, the parallel connecting rod 24 is used to connect and fix the two groups of lower trusses 21 and the two adjacent groups of upper trusses 23 to ensure the overall structural strength and verticality of the truss 2; this embodiment only describes the working conditions of two groups of brackets 1, and the working conditions of multiple groups of brackets 1 are consistent with the principles of the working conditions of two groups of brackets 1.

[0044] The support frame 3 is used to support the truss 2, such as Figure 1As shown, when one group of lower trusses 21, web members 22 and upper trusses 23 are assembled, and the other group of lower trusses 21, web members 22 and upper trusses 23 are not assembled, the parallel connecting rod 24 cannot be used to connect the lower trusses 21, web members 22 and upper trusses 23, resulting in the truss 2 being unable to maintain verticality. The support frame 3 is fixedly arranged between the other bracket 1, the lower truss 21 and the upper truss 23. The support of the lower truss 21, web members 22 and upper truss 23 by the support frame 3 can ensure the verticality of the truss 2. When the second group of lower trusses 21, web members 22 and upper trusses 23 are assembled, a parallel connecting rod 24 is set between the two groups of lower trusses 21, web members 22 and upper trusses 23, and the support frame 3 can be disassembled.

[0045] like Figure 1 and Figure 2 As shown, the support frame 3 includes an oblique rod 31, a horizontal rod 32 and a vertical rod 33. The oblique rod 31 is fixedly arranged between the upper truss 23 and another bracket 1; the horizontal rod 32 is fixedly arranged between the lower truss 21 and the oblique rod 31; the vertical rod 33 is fixedly arranged between the oblique rod 31 and the horizontal rod 32. The three form a triangle with good stability and can provide good support for the truss 2; it is preferred that the oblique rod 31, the horizontal rod 32 and the vertical rod 33 form a right-angled triangle, and the horizontal rod 32 and the vertical rod 33 are perpendicular to each other, and the axis of the horizontal rod 32 is parallel to the horizontal plane, that is, the horizontal rod 32 is arranged horizontally and the vertical rod 33 is arranged vertically, which helps to measure the verticality of the truss 2.

[0046] In order to make the support frame 3 adapt to different working conditions or trusses 2 and brackets 1 of different specifications, the length of the diagonal rod 31 can be adjusted, thereby improving the adaptability of the support structure.

[0047] like Figure 3 As shown, the diagonal rod 31 includes a bottom tube 311, a top tube 312 and a fixing bolt 313. One end of the bottom tube 311 is fixed to the bracket 1 without the truss 2; one end of the top tube 312 is fixed to the upper truss beam 23, and the end of the bottom tube 311 away from the bracket 1 is slidably set in the top tube 312, and a threaded hole 301 is provided on the side wall of the top tube 312; the fixing bolt 313 is connected to the threaded hole 301 through threaded cooperation and abuts against the bottom tube 311; when the fixing bolt 313 is tightened, the fixing bolt 313 can abut and fix the bottom tube 311, and when the fixing bolt 313 is loosened, the bottom tube 311 and the top tube 312 can slide, thereby realizing the adjustment of the length of the diagonal rod 31.

[0048] The top tube 312 and the bottom tube 311 are fixed by fixing bolts 313, which can facilitate the adjustment of the length of the diagonal rod 31, but its fixing firmness is relatively poor and it is easy to slip. In order to solve this problem, the diagonal rod 31 also includes a limiting tube 314, such as Figure 4As shown, a limiting groove 302 is provided on the circumferential side of the bottom tube 311, and a limiting tube 314 is slidably set in the limiting groove 302. The limiting groove 302 is a circular groove, and the limiting tube 314 is sleeved on the outer side of the bottom tube 311, and the fixing bolt 313 is abutted against the inner wall of the limiting groove 302; a through hole 303 is provided on the limiting tube 314, and the fixing bolt 313 is passed through the through hole 303. Even if the fixing bolt 313 becomes loose, causing the top tube 312 and the bottom tube 311 to slip, the sliding length of the top tube 312 and the bottom tube 311 can be limited by the abutment of the end side of the limiting groove 302 against the limiting tube 314, so as to prevent the entire truss 2 from overturning.

[0049] like Figure 3 As shown, there are multiple threaded holes 301, and the multiple threaded holes 301 are evenly distributed along the axial direction of the top tube 312. By utilizing the cooperation between the fixing bolts 313 and different threaded holes 301, the length of the inclined rod 31 can be adjusted in a large range, and by utilizing the sliding cooperation between the limiting tube 314 and the limiting groove 302, the length of the inclined rod 31 can be adjusted in a small range.

[0050] like Figure 2 As shown, the support frame 3 also includes a fixed plate 34 and two rotating seats 35. The fixed plate 34 is fixedly set at the end of the cross bar 32 away from the diagonal bar 31, and is detachably fixedly connected to the lower truss 21; the two rotating seats 35 are respectively rotatably set at the two ends of the diagonal bar 31, and are respectively detachably fixedly connected to the upper truss 23 and the bracket 1 without the truss 2; when the length of the diagonal bar 31 changes, the diagonal bar 31 is installed on the bracket 1 and the upper truss 23 by utilizing the rotation of the rotating seat 35 and the diagonal bar 31 to quickly realize the connection between the truss 2 and the bracket 1 and the support frame 3.

[0051] like Figure 2 As shown, the support frame 3 further includes two pipe clamps 36 , and the bottom pipe 311 and the cross bar 32 as well as the top pipe 312 and the vertical bar 33 are fixedly connected via the pipe clamps 36 .

[0052] like Figure 5As shown, the pipe clamp 36 includes a rotating shaft 361, two rotating cylinders 362 and two tightening bolts 363. The two rotating cylinders 362 are rotatably arranged at both ends of the rotating shaft 361. The bottom tube 311, the top tube 312, the cross bar 32 or the vertical bar 33 are slidably arranged in the rotating cylinder 362; the tightening bolts 363 pass through the rotating cylinder 362 and are connected to it by threaded engagement, and the two correspond one to one. The tightening bolts 363 are engaged with the bottom tube 311, the top tube 312, the cross bar 32 or the vertical bar 33 in the rotating cylinder 362. The top tube 312, the cross bar 32 or the vertical bar 33 are supported against each other; when the tightening bolt 363 is loosened, the bolt 363 is tightened to support and fix the bottom tube 311, the top tube 312, the cross bar 32 or the vertical bar 33. On the contrary, the bottom tube 311, the top tube 312, the cross bar 32 or the vertical bar 33 in the rotating drum 362 can slide, so that when the length of the inclined rod 31 changes, the positions of the cross bar 32 and the vertical bar 33 are also adjusted accordingly.

[0053] A method of using the truss support structure of the utility model is as follows:

[0054] First, fix and install the two brackets 1, then assemble one group of lower trusses 21, webs 22 and upper trusses 23 (lower trusses 21, webs 22 and upper trusses 23 on the same vertical plane) on the first bracket 1, and then fix the support frame 3 on the assembled lower trusses 21, upper trusses 23 and another bracket 1, and ensure the verticality of the assembled lower trusses 21, webs 22 and upper trusses 23, then assemble the second group of lower trusses 21, webs 22 and upper trusses 23 on another bracket 1, finally set parallel connecting rods 24 between the two groups of assembled lower trusses 21 and upper trusses 23 for connection, and remove the support frame 3.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
