Description

Technical Field

[0001] This utility model relates to the field of formwork support technology, and in particular to a high-strength stair formwork support structure. Background Technology

[0002] A staircase formwork structure is a temporary device used to support and fix staircase formwork during building construction. It typically consists of steel pipes, connectors, and support rods. Its main function is to ensure the stability and shape of the staircase formwork during concrete pouring, preventing deformation or displacement of the formwork.

[0003] When using staircase formwork structures, sometimes it is inconvenient to make adjustments to certain parts of the structure after the formwork is erected, which leads to more time being spent on modifications and affects subsequent processing operations. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-strength staircase support frame structure.

[0005] This utility model is achieved by the following technical solution: a high-strength stair support frame structure, including a support frame, a support base fixedly connected to the lower end of the support frame, a first connecting component provided on the surface of the support frame, a reinforcing crossbar fixedly connected to the support frame through the first connecting component, a second connecting component provided on the surface of the support frame, and a reinforcing diagonal bar fixedly connected to the support frame through the second connecting component;

[0006] The first connecting assembly includes a first connecting sleeve, a rotating shaft fixedly connected to the surface of the first connecting sleeve, a second connecting sleeve rotatably connected to the surface of the rotating shaft, a first retaining plate slidably connected to the inner wall of the first connecting sleeve, a second retaining plate slidably connected to the inner wall of the second connecting sleeve, a rotating screw rotatably connected to the inner walls of both the first and second retaining plates, a limit bracket threadedly connected to the surface of the rotating screw, a connecting frame fixedly connected to the side end of the rotating screw, a fixed shaft fixedly connected to the surface of the connecting frame, a sliding sleeve slidably connected to the surface of the fixed shaft, a limit retaining shaft fixedly connected to the side end of the first connecting sleeve, a first spring sleeved on the surface of the fixed shaft, an mounting sleeve fixedly connected to the surface of the second connecting sleeve, a sliding shaft slidably connected to the inner wall of the mounting sleeve, and a second spring sleeved on the surface of the sliding shaft.

[0007] By using the above technical solution, the support frame and the reinforcing crossbar are connected by fixed shafts on both sides of the rotation, and the position is limited by parts such as limit clamps. This design makes the assembly and adjustment of the overall structure more convenient and the use of the device more convenient.

[0008] As a further improvement to the above solution, the surface of the sliding shaft is engaged with the inner wall of the rotating shaft, and the second spring is located inside the mounting sleeve.

[0009] The above technical solution provides a rotation limit for the subsequent use of the second connecting sleeve, making the subsequent use of the device more stable.

[0010] As a further improvement to the above solution, the surface of the limiting pin shaft is engaged with the inner wall of the limiting bracket.

[0011] As a further improvement to the above solution, the surface of the limiting pin shaft is slidably connected to the inner wall of the connecting frame.

[0012] As a further improvement to the above solution, the support frame is located between the first connecting sleeve and the first clamping plate.

[0013] As a further improvement to the above solution, the reinforcing crossbar is located between the second connecting sleeve and the second clamping plate.

[0014] As a further improvement to the above solution, the first connecting component and the second connecting component have the same structure.

[0015] The above technical solution enables the overall structure to easily connect the support frame, reinforcing crossbars, and reinforcing diagonal braces, thus improving the overall practicality of the device.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention involves fitting a first connecting sleeve onto the surface of a support frame and adjusting it to a suitable position. Once the first connecting sleeve is in the correct position, pulling it compresses a first spring, simultaneously causing the limiting pin to separate from the limiting bracket, thus releasing the rotational limitation on the connecting frame. At this point, the fixed shaft can be rotated to drive a rotating screw. Simultaneously, the rotating screw causes the first locking plate to press against the support frame inside the first connecting sleeve, thereby fixing the position of the first connecting sleeve. After the first connecting sleeve is fixed, the tension on the sliding sleeve is released. The sliding sleeve then rebounds under the action of the first spring, thus... The movable limit pin re-engages into the interior of the limit bracket, thereby limiting the rotation of the rotating screw and preventing it from loosening during subsequent use. After the first connecting sleeve is fixed and the angle of the second connecting sleeve is adjusted, the reinforcing crossbar is passed through the inner wall of the second connecting sleeve and positioned appropriately. At this point, the fixing steps at the first connecting sleeve are repeated to fix the reinforcing crossbar. The design of using the fixed shafts on both sides of the rotation to connect the support frame and the reinforcing crossbar, and using the limit pin and other parts to limit the position, makes the assembly and adjustment of the overall structure more convenient and the use of the device more convenient.

[0018] This invention uses a sliding shaft to compress a second spring, simultaneously separating the sliding shaft from the rotating shaft and releasing the rotation limit of the second connecting sleeve. At this point, the second connecting sleeve can be rotated to adjust its angle with the first connecting sleeve. Then, the tension on the sliding shaft is released, allowing it to re-insert into the inner wall of the rotating shaft under the action of the second spring, preventing the second connecting sleeve from rotating during subsequent use. This design, using a sliding shaft to control the limit between the rotating shaft and the second connecting sleeve, achieves the goal of conveniently changing the angle of the second connecting sleeve while preventing its rotation during operation, thus improving the practicality of the device.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0028] Please combine Figure 1-5This embodiment of a high-strength staircase formwork structure includes a support frame 1, a support base 2 fixedly connected to the lower end of the support frame 1, a first connecting component 3 provided on the surface of the support frame 1, a reinforcing crossbar 4 fixedly connected to the support frame 1 through the first connecting component 3, a second connecting component 5 provided on the surface of the support frame 1, and a reinforcing diagonal bar 6 fixedly connected to the support frame 1 through the second connecting component 5.

[0029] The first connecting assembly 3 includes a first connecting sleeve 301. A rotating shaft 302 is fixedly connected to the surface of the first connecting sleeve 301. A second connecting sleeve 303 is rotatably connected to the surface of the rotating shaft 302. A first clamping plate 304 is slidably connected to the inner wall of the first connecting sleeve 301. A second clamping plate 305 is slidably connected to the inner wall of the second connecting sleeve 303. A rotating screw 306 is rotatably connected to the inner walls of both the first clamping plate 304 and the second clamping plate 305. A limit bracket 307 is threadedly connected to the surface of the rotating screw 306. A connecting frame 308 is fixedly connected to the side end of the rotating screw 306. A fixing shaft 309 is fixedly connected to the surface of the connecting frame 308. The surface of the first connecting sleeve 301 is slidably connected to a sliding sleeve 310. The side end of the first connecting sleeve 301 is fixedly connected to a limiting pin 311. The surface of the fixed shaft 309 is sleeved with a first spring 312. The surface of the second connecting sleeve 303 is fixedly connected to a mounting sleeve 313. The inner wall of the mounting sleeve 313 is slidably connected to a sliding shaft 314. The surface of the sliding shaft 314 is sleeved with a second spring 315. By using the fixed shafts 309 on both sides to connect the support frame 1 and the reinforcing crossbar 4, and by using the limiting pin 311 and other parts to limit the position, the design makes the assembly and adjustment of the overall structure more convenient and the use of the device more convenient.

[0030] The surface of the sliding shaft 314 engages with the inner wall of the rotating shaft 302, and the second spring 315 is located inside the mounting sleeve 313.

[0031] The surface of the limiting pin 311 engages with the inner wall of the limiting bracket 307.

[0032] The surface of the limiting pin 311 is slidably connected to the inner wall of the connecting frame 308.

[0033] The support frame 1 is located between the first connecting sleeve 301 and the first clamping plate 304.

[0034] The reinforcing crossbar 4 is located between the second connecting sleeve 303 and the second clamping plate 305.

[0035] The first connecting component 3 and the second connecting component 5 have the same structure. This design allows the overall structure to be easily connected between the support frame 1, the reinforcing crossbar 4 and the reinforcing diagonal bar 6, thus improving the overall practicality of the device.

[0036] The implementation principle of a high-strength staircase formwork support structure in this application embodiment is as follows: When using this structure, the support frame 1 is first fixed to the required position by the support base 2. Then, the first connecting sleeve 301 is put onto the surface of the support frame 1 and adjusted to a suitable position. After the first connecting sleeve 301 reaches the suitable position, the first connecting sleeve 301 is pulled to drive the first spring 312 to compress, and at the same time, the limiting pin 311 is separated from the limiting bracket 307, thereby releasing the rotation limit on the connecting frame 308. At this time, the fixed shaft 309 can be rotated to drive the rotating screw 306 to rotate. While the rotating screw 306 is rotating, the first spring 312 is also rotated. The clamping plate 304 presses against the support frame 1 inside the first connecting sleeve 301 to fix the position of the first connecting sleeve 301. After the first connecting sleeve 301 is fixed, the tension on the sliding sleeve 310 is released. At this time, the sliding sleeve 310 rebounds under the action of the first spring 312, thereby driving the limiting clamping shaft 311 to re-clamp into the limiting bracket 307, thus providing a limit for the rotation of the rotating screw 306 to prevent the rotating screw 306 from loosening in subsequent use. After the first connecting sleeve 301 is fixed, the sliding shaft 314 is pulled to drive the second spring 315 to press, and at the same time, the sliding shaft 314 and... The rotating shaft 302 is separated, and the rotation limit of the second connecting sleeve 303 is released. At this time, the second connecting sleeve 303 can be rotated to adjust the angle between it and the first connecting sleeve 301. Then, the tension on the sliding shaft 314 is released, and it is reinserted into the inner wall of the rotating shaft 302 under the action of the second spring 315 to prevent the second connecting sleeve 303 from rotating in subsequent use. After the angle of the second connecting sleeve 303 is adjusted, the reinforcing crossbar 4 is passed through the inner wall of the second connecting sleeve 303 and moved to the appropriate position. At this time, the fixing steps at the first connecting sleeve 301 are repeated to fix the reinforcing crossbar 4. After completion, the second connecting component 5 is fixed to the reinforcing diagonal bar 6 and the support frame 1 in the same way as the first connecting component 3, thereby completing the assembly of the structure. This device uses multiple sets of first connecting components 3 and second connecting components 5 to connect the support frame 1 with the reinforcing crossbar 4 and the reinforcing diagonal bar 6, and can adjust the position between each support. This design achieves the purpose of conveniently assembling the structure and conveniently adjusting the position of parts such as the rotating screw 306 when there are problems with the position of parts in the structure, making the device more convenient to use and improving its practicality.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
