Description

Technical Field

[0001] This utility model relates to the field of steel structure construction technology, and more specifically, to a single-tube support device that can quickly adjust the elevation of a space frame. Background Technology

[0002] In the field of steel structure construction, a space frame is a spatial structure composed of multiple members connected by nodes in a certain grid pattern. Conventional space frame assembly supports use single-tube bracing. The single tube is cut according to the support height, with one end welded to the floor slab embedded part and the other end supported under the space frame sphere. The support height is fixed and cannot be adjusted, requiring a large number of support tubes that cannot be reused. Furthermore, single tubes have poor resistance to lateral deformation, thus affecting stability and posing certain safety hazards. The installation of embedded parts and dismantling of devices also consumes a lot of time and materials due to the difficulty of construction. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] As shown in the figure, this utility model discloses a single tube support device that can quickly adjust the elevation of a space frame, including a circular tube support 1, which supports the entire space frame system with the bottom of the space frame sphere as the contact surface.

[0023] The bottom of the circular tube support 1 is installed in the middle of support plate 2. Support plate 2 is installed on support plate 3. Support plate 4 is located at the lower end of support plate 3. Support plate 4 is fixed here, while support plate 3 can be raised and lowered. Support plate 4 is connected to the ground by expansion bolts. After the entire grid frame is assembled, the entire device can be dismantled by removing the expansion bolts.

[0024] Two double-ear plates 5 and two single-ear plates 6 are installed at the lower end of support plate 2 3 and the upper end of support plate 3 4, respectively. Adjustable steel rods 7 are installed between the upper single-ear plate 6 and the lower double-ear plate 5. There are four adjustable steel rods 7 in total. Two adjacent adjustable steel rods 7 are connected by connecting round rods 8. The two connecting round rods 8 are parallel and each of them is equipped with a perforated nut 9. The adjusting screw 10 is threadedly connected to the two perforated nuts 9, and the threads of the two perforated nuts 9 turn in opposite directions. When the adjusting screw 10 rotates, it drives the relative position of the two perforated nuts 9 to change, thereby adjusting the position of the connecting round rods 8, adjusting the top position of the adjustable steel rods 7, and thus driving support plate 2 3 to rise and fall, and finally driving the round tube support 1 to rise and fall.

[0025] The double-ear plate 5 is composed of two parallel single-ear plates 6. The single-ear plates 6 and the double-ear plates 5 are connected to the adjustable steel rod 7 by connecting pins. The bottom of the adjustable steel rod 7 rotates around the connecting pin connected to the lower single-ear plate 6 or double-ear plate 5, and the top of the adjustable steel rod 7 is raised and lowered, ultimately adjusting the height of the circular tube support 1, thereby adjusting the height of the space frame.

[0026] In one embodiment of this utility model, each adjustable steel rod 7 includes three rod bodies 71. Both ends of the rod body 71 are provided with rod mounting holes 711. One end of one rod body 71 is located at one end of the other two parallel rod bodies 71. The connecting round rod 8 passes through the rod mounting holes 711 of the three rod bodies 71.

[0027] The bottom of the bottom rod 71 remains at a constant height and rotates only around the connecting pin. The top of the bottom rod 71 and the bottom of the top rod 71 move with the connecting round rod 8, thereby driving the top of the top rod 71 to rise and fall, and ultimately driving the round tube support 1 to rise and fall.

[0028] In one embodiment of this utility model, a washer and a nut 11 are installed at the connection between the rod 71 and the connecting round rod 8. The nut 11 serves to fix the rod 71 and prevent it from sliding along the connecting round rod 8. Of course, external threads are required on both sides of the connecting round rod.

[0029] In one embodiment of this utility model, two anti-roll bars 12 are also included. Each anti-roll bar 12 includes two anti-roll bar bodies 121. Both ends of the anti-roll bar bodies 121 are equipped with anti-roll bar body mounting holes 1211. One end of the two anti-roll bar bodies 121 is connected together. The connection point of the two anti-roll bar bodies 121 is sleeved on the connecting round rod 8. The top of the upper anti-roll bar body 121 is connected to the top of one of the adjustable steel rods 7, and the bottom of the lower anti-roll bar body 121 is connected to the bottom of the other adjustable steel rod 7. The two adjustable steel rods 7 are installed on both sides of the connecting round rod 8.

[0030] The anti-tilt bar 12 is used to connect the top and bottom of two adjustable steel rods 7 installed on the same connecting round rod 8, and prevents the overall structure from tilting when the adjustable steel rods 7 are raised or lowered.

[0031] In one embodiment of this utility model, one end of the circular tube support 1 is welded to the support plate 2, and a plurality of circumferentially distributed reinforcing ribs 13 are welded between the outer side of the circular tube support 1 and the support plate 2. The reinforcing ribs 13 serve to resist lateral deformation.

[0032] In one embodiment of this utility model, the four corners of support plate 12 and support plate 23 are connected by bolts 14.

[0033] In one embodiment of this utility model, two double-ear plates 5 and two single-ear plates 6 are diagonally distributed on the lower end of the second support plate 3 and the upper end of the third support plate 4. The single-ear plate is directly below the upper double-ear plate 5, and the double-ear plate is directly below the upper single-ear plate.

[0034] In one embodiment of this utility model, a hollow round steel bar 15 is installed at one end of the adjusting screw 10, and a round steel bar 26 is installed at the round steel bar 15. This utility model allows the round steel bar 26 to be manually driven to rotate, which in turn drives the adjusting screw 10 to rotate via the round steel bar 15.

[0035] Rotating the adjusting screw 10 changes the included angle of the adjustable steel rod 7, thereby changing the height of the circular tube support 1 and realizing the conversion of kinetic energy into gravitational potential energy.

[0036] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
