Description

Technical Field

[0001] The invention relates to the technical field of tire frame tubes, and in particular to a combined supporting tire frame tube for truss assembly. Background Art

[0002] The tire frame tube is a kind of mold, which refers to the scaffolding that mainly bears the load and force. It is a special process equipment for facilitating the assembly and welding of mechanical equipment. It is widely used in formwork engineering, steel structure installation engineering, and bridge engineering. Truss refers to a lattice structure composed of round rods connected to each other at the ends. Trusses make the truss structure economical in material and light in weight. It is easy to form various shapes to adapt to different uses, such as simple supported trusses, arches, frames and towers. During the construction of trusses, tire frame tubes are needed for support and limitation.

[0003] When existing trusses are constructed, most of them use scaffolding as the frame tube, which is inconvenient to construct. If the area cannot be supported by the scaffolding, it needs to be made on site. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a combined support frame tube for truss assembly, including a bottom support member, a connecting rod, a middle support member and an upper support member. The above components can be assembled and combined, and flexibly constructed according to the construction process of the truss.

[0005] The bottom support member includes a vertical tube, and a plurality of support rods are arranged at equal angles around the vertical tube. The upper ends of the support rods are rotatably connected to the upper side walls of the vertical tube, and the middle part of the support rod is threadedly matched with a first screw rod, and the threads at both ends of the first screw rod have opposite rotation directions. The vertical tube can improve the stability of the support under the action of the support rod, and the arrangement of the first screw rod can realize the adjustment of the length of the support rod, thereby controlling the support angle of the vertical tube.

[0006] The middle support is mounted above the bottom support, and includes a first support tube, a side wall of the first support tube is provided with a plurality of threaded holes, and bolts are provided in the threaded holes. According to the need of the support height, the middle support can be built end to end.

[0007] Both ends of the connecting rod are provided with a second bayonet, and the second bayonet is matched with the bolt. The connecting rod is used to connect the adjacent middle connecting pieces, so as to improve the support stability of the entire tire frame tube, and the connecting rod can be built horizontally or diagonally as needed. After the connecting rod is placed on the bolt, the screw needs to be tightened to prevent the connecting rod from falling.

[0008] The upper end of the middle support is provided with an upper support, and the upper support includes a second support tube, the upper end of the second support tube is threadedly provided with a second screw, and the upper end of the second screw is fixedly connected to a support plate. The support plate is provided with a through hole, and the truss is placed on the support plate during support. If positioning / fixing is required, bolts / U-shaped screws can be used to pass through the through holes for fixing.

[0009] Preferably, the lower end of the support rod is rotatably connected to a support pad, thereby increasing the support area and reducing damage to the ground.

[0010] Preferably, the lower end of the vertical pipe is fixedly connected with a base. The base and the support pad have the same function, increasing the support area and reducing damage to the ground.

[0011] Preferably, a first bayonet with a regular hexagonal cross-section is provided in the middle of the first screw rod. The first screw rod can be rotated by clamping the first bayonet with a wrench, thereby adjusting the length of the support rod.

[0012] Preferably, the lower end of the first support tube is fixedly connected with a first plug section, and the first plug section is matched with the upper end of the vertical tube. That is, the lower part of the middle support member is directly plugged into the upper part of the bottom support member. This method has the advantage of convenient lifting, but it should be noted that in order to ensure the stability of the connection, the first plug section should be long enough.

[0013] Preferably, the lower end of the second support tube is fixedly connected with a second plug section, and the second plug section is matched with the upper end of the first support tube. Similarly, the upper support member is plugged into the middle support member through the second plug section, and its length is controlled to be consistent with the first plug section.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The bottom support, connecting rod, middle support and upper support are fixed by splicing, which has the advantages of flexible construction and easy use.

[0016] 2. The upper support member can be set to increase the height to meet the final support gap, and the support rod ensures the support stability of the bottom support member.

[0017] 3. A connecting rod is provided to achieve connection between adjacent middle supports, improve the overall stability of the tire frame tube, and the connecting rod is fixed with bolts. In addition, the bolts also facilitate the lifting of the middle support. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0027] like Figure 1 As shown, a combined support frame tube for truss assembly includes a bottom support 1, a connecting rod 2, a middle support 3 and an upper support 4. According to the height requirement of the support, multiple middle supports 4 can be connected end to end, and the connecting rod 2 can be built horizontally or obliquely to raise the adjacent middle supports 4.

[0028] like Figure 2 As shown, the bottom support 1 includes a vertical tube 14, and a plurality of support rods 12 are arranged at equal angles around the vertical tube 14 to support the vertical tube 14. The upper end of the support rod 12 is rotatably connected to the upper side wall of the vertical tube 14. The support angle of the support rod 12 can be adjusted according to different terrains. The middle thread of the support rod 12 is matched with a first screw rod 16, and the threads at both ends of the first screw rod 16 rotate in opposite directions. The first screw rod 16 is rotated to adjust the length of the support rod 12. First, it is used for support in different terrains. Second, it is used to ensure that the vertical tube 14 is at a correct support angle to ensure the stability of the truss support.

[0029] like Figure 3 As shown, the middle support member 3 is erected above the bottom support member 1, and the middle support member 3 includes a first support tube 32. The side wall of the first support tube 32 is provided with a plurality of threaded holes, and the threaded holes are matched with bolts 33. The installation of the bolts 33 can be coordinated according to the requirements of the construction site. All the threaded holes in the figure are matched with bolts 33. During the lifting process, the bolts 33 can be installed on the upper end of the first support tube 32, and the hook is connected to the bolts 33 for lifting.

[0030] like Figure 5 As shown, both ends of the connecting rod 2 are provided with a second bayonet 21, and the second bayonet 21 is matched on the bolt 33. After the second bayonet 21 is engaged with the bolt 33, it is necessary to tighten the bolt 33 to clamp and fix the connecting rod 2. When the connecting rod 2 is installed, it is installed horizontally or obliquely according to the installation needs. Therefore, it is necessary to customize connecting rods 2 of different lengths to meet construction requirements.

[0031] like Figure 4 As shown, an upper support member 4 is mounted on the upper end of the middle support member 3, and the upper support member 4 includes a second support tube 42. A second screw rod 43 is threadedly provided on the upper end of the second support tube 42. When the second screw rod 43 is rotated, the height of the upper support member 4 changes, which meets the support requirement of uncertain distance between the middle support member 3 and the truss. A support plate 44 is fixedly connected to the upper end of the second screw rod 43. The support plate 44 is used to support the truss from the bottom. At the same time, a through hole is provided on the support plate 44. If the truss needs to be fixed and limited, a U-shaped screw or other connecting piece can be used to fix the truss.

[0032] Furthermore, a movable connection is adopted between the upper end of the second screw 43 and the support plate 44, and a first snap-in 15 with the same structure as the first screw 16 is provided on the second screw 43, so that the second screw 43 can also be rotated when the support plate 44 is supporting, which is conducive to the removal of the tire frame tube at a later time.

[0033] like Figure 2 As shown, the lower end of the support rod 12 is rotatably connected to the support pad 11, and the lower end of the vertical pipe 14 is fixedly connected to the base 13. The support pad 11 and the base 13 have the same function, which is to increase the support area, improve the stability of the support, and reduce the damage to the support ground.

[0034] A first bayonet 15 with a regular hexagonal cross section is provided in the middle of the first screw rod 16. The first bayonet 15 is clamped with a wrench to rotate the first screw rod 16 to adjust the length of the support rod 12.

[0035] like Figure 3As shown, the lower end of the first support tube 32 is fixedly connected with a first plug section 31, and the first plug section 31 is matched with the upper end of the vertical tube 14. To ensure the stability of the connection between the bottom support member 1 and the middle support member 3, the first plug section 31 should be long enough.

[0036] like Figure 4 As shown, the lower end of the second support tube 42 is fixedly connected with the second plug section 41, and the second plug section 41 is matched with the upper end of the first support tube 32. In order to ensure the stability of the connection between the upper support member 4 and the middle support member 3, the second plug section 42 should also be long enough.

[0037] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
