Description

Technical Field

[0001] This application relates to the field of building construction, specifically to a standardized support frame. Background Technology

[0002] In construction engineering, large-span structures are typically constructed using assembly (welding) and hoisting methods, with support frames being widely used during the assembly (welding) process. Conventional support frames are welded from steel, angle iron, and reinforcing bars, and their dimensions are fixed, suitable only for a specific assembly condition. Especially for large-span structures with suspended components, when the support frame height is insufficient, re-welding or lengthening is required, resulting in low construction efficiency and difficulty in controlling the support height accuracy. To improve compressive strength, overturning resistance, and anti-displacement effects, some support frame bases are large, even anchored to the ground, which easily leads to difficulties in installation and dismantling and affects the ground waterproofing. Furthermore, some support frames are assembled, but only support certain specific heights, unable to achieve dynamic adjustment of angle and height, and have poor seismic resistance and stability, limiting their applicability.

[0023] Example 1

[0024] A standardized support frame, such as Figures 1-6 As shown, the device includes a standard support frame unit and energy-dissipating rods 1 connected between the standard support frame units. The standard support frame unit includes a bottom support 2, a middle standard support 3, and a top support 4 arranged sequentially from bottom to top. The middle standard support 3 includes a steel pipe support 31 and an annular steel plate 32 located in the middle of the steel pipe support 31. Pressure-bearing members 33 are sleeved on the steel pipe support 31, above and below the annular steel plate 32. The pressure-bearing members 33 include a middle sleeve pipe and a pressure-bearing plate located on the outer facade of the middle sleeve pipe. The steel pipe support 31 passes through the center of the annular steel plate 32 and is welded and fixed to the annular steel plate 32. The annular steel plate 32 is provided with perforations at intervals for connecting the energy-dissipating rods 1 on both sides.

[0025] The energy-dissipating rod 1 includes a central connecting rod 11, a spring 12 located on the central connecting rod 11, and a hook 13 for connecting the annular steel plate 32.

[0026] Several pressure plates are circumferentially spaced on the outer wall of the central sleeve pipe. The width of the pressure plates narrows from the middle to both sides. Preferably, there are four pressure plates. The bottom support member 2 includes a bottom support panel, a two-section angle-adjustable support on the bottom support panel, and a stiffening plate between the two-section angle-adjustable support and the support panel. The top support member 4 includes a top support panel, a two-section angle-adjustable support on the top support panel, and a stiffening plate between the two-section angle-adjustable support and the top support panel. The upper and lower two-section angle-adjustable supports are threadedly connected to the steel pipe support 31. The upper and lower parts of the steel pipe support 31 are provided with internal thread joints and external thread joints.

[0027] Example 2

[0028] Based on Embodiment 1, the middle connecting rod 11 is an adjustable support rod formed by at least two steel pipes connected by threads. The two-section angle adjustable support includes an upper support rod 6, a spherical rotating shaft 7, a spherical cavity 8 for limiting the spherical rotating shaft 7, and a lower support rod 9 arranged in sequence. The diameter of the upper circular opening of the spherical cavity 8 should be smaller than the diameter of the spherical cavity 8. The bottom surface of the bottom support member 2 is provided with a groove, and the top support panel is provided with a circular or rectangular limiting groove 5.

[0029] Example 3

[0030] The standardized support frame in this embodiment uses the following components: a top support (with steering function), a standard support, a bottom support (with steering function), a self-adjusting tie rod, and a stress sensor (with Bluetooth transmission function). The performance and parameter requirements of each component are as follows:

[0031] The top support component includes a panel, supporting steel pipe (internal thread), stiffening plate, and universal joint. The panel can be made with square, circular, or other shaped grooves and can be replaced to facilitate the limiting of the upper structure and prevent slippage. The standard support component consists of a supporting upright, a ring-shaped steel plate, and a pressure-bearing component. The pressure-bearing component has a circular cavity, and the remaining parts are supplemented with supporting steel components as needed to increase rigidity and bearing strength. The bottom support component includes a panel, supporting steel pipe (external thread), stiffening plate, and universal joint. The bottom of the panel has grooves to improve its anti-slip and anti-deviation effects. The self-adjusting tie rod is mainly used to improve the overturning resistance of the jig and reduce energy consumption under vibration loads. The thread adjustment length should be controlled within 0-100mm. The stress sensor is mainly used to monitor the top load borne by the jig and to fine-tune the jig according to the load deviation to ensure uniform stress at each support point. To ensure the overall support strength of the jig and avoid bending and shear failure, the thread adjustment height range of the top and bottom support components should be controlled within 0-100mm.

[0032] The installation process for this standardized support frame is as follows: frame positioning → assembly of standard support components and stress sensors → assembly of bottom and top support components → frame positioning and leveling → installation of self-adjusting tie rods.

[0033] The installation process requirements are as follows:

[0034] (1) Carrier positioning

[0035] Based on the longitudinal and transverse dimensions of the superstructure, the nodes of the components requiring support are laid out using planar projection. The three-dimensional coordinates of the supporting components can be extracted using the BIM model to generate a cloud data of the support frame points. The support frame points are then located using surveying instruments such as a total station, with the center point or four corners serving as positioning markers. If the ground is not flat enough, high-strength polymer grouting can be used for leveling to reduce the initial error of the support frame.

[0036] (2) Assembly of standard support components and stress sensors

[0037] Before assembling the standard support components, the stress sensor is installed close to the outer wall of the standard support component near the annular steel plate. It primarily monitors the minute deformation of the standard support component under stress and converts this deformation into a bearing load, which is then transmitted to the back-end system. The standard support components are then assembled on the ground. Two bearing components are sequentially passed through the uprights of the standard support component. A cavity needs to be pre-reserved in the bearing component where the stress sensor is installed. If extension is required depending on the support height, the two standard support components are tightened using internal and external threads, ensuring that the extended bearing component is firmly secured.

[0038] (3) Assembly of bottom support and top support

[0039] Install the support components in the following order: first the bottom support, then the top support. During the installation of the bottom support, adjust the universal joint according to the flatness or slope of the ground and monitor its level to prevent instability of the support frame due to eccentric stress. When installing the top support, select and replace the appropriate panel according to the shape of the top structure to ensure maximum fit of the support surface. Connect the bottom support, top support, and standard support components sequentially using internal and external threads, and adjust the height of the entire support frame to near the support height.

[0040] (4) Positioning and leveling of the tire frame

[0041] Erect the support frame and move it to the frame positioning point. One person adjusts the thread length of the bottom or top support component of the frame and fine-tunes and fixes the angle of the universal joint, while another person verifies the support height and angle of the frame. After all frames are leveled, place the superstructure on top of the top support panel of each support frame. Analyze the load data transmitted via Bluetooth from the stress sensor. If the load deviation between adjacent frames exceeds 5%, the height and angle of the frame need to be adjusted and leveled again to ensure that all support frames are under the same stress state.

[0042] (5) Installation of self-adjusting tie rod

[0043] Based on the installation height of the support frame, the weight of the superstructure, and on-site conditions (wind power, etc.), self-adjusting tie rods are installed accordingly. The tie rod ends are sequentially connected to the annular holes of the adjacent standard support ring steel plates, enabling 360° omnidirectional adjustment. If the tie rod length is insufficient, an extension rod (threaded at both ends) can be used to lengthen it. Once the ends are connected, the energy-dissipating spring of the self-adjusting tie rod is in a taut state and the deformation value reaches more than 5% of its original value.

[0044] When removing the support frame, simply reverse the steps 2-5 of the installation process.

[0045] (1) The groove shape and size of the top support panel can be made according to actual needs, and can be replaced according to the shape of the upper support structure during use.

[0046] (2) The width of the annular hole of the ring steel plate is slightly larger than the size of the self-adjusting tie rod ring, which makes it easier to tie the tie rod. The tie rod can be tied 360° through the annular hole, which is more convenient.

[0047] (3) The module of the standard support can be adjusted according to actual needs, and the height of the two pressure-bearing parts plus the thickness of the annular steel plate is consistent with the length of the standard support except for the thread.

[0048] (4) The energy-consuming spring of the self-adjusting tie rod is mainly aimed at reducing the energy consumption of vibration load. In addition to improving the overall stability and anti-overturning effect of the frame, it also plays a certain role in earthquake resistance.

[0049] (5) The installation form of the support frame is not limited to the above three types, and can be adjusted according to the actual application situation on site.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
