[0042] The embodiments of the present invention are described below with reference to the accompanying drawings.

[0043] like Figure 1 As shown, the present invention proposes a modular temporary support device, including a temporary support 20 and a lifting device 10; the temporary support 20 includes a plurality of support modules 21, and the support modules 21 are detachably connected to each other; the lifting device 10 is arranged around the temporary support 20, and is provided with a lifting mechanism 16 and a movable corbel 13, the lifting mechanism 16 is used to lift the support module 21 or a combined module formed by combining a plurality of the support modules 21 within the height range of the lifting device 10, and place it on the movable corbel 13, thereby realizing the top-down installation of the temporary support 20 in a limited space.

[0044] Specifically, the above-mentioned support module 21 is prefabricated in the factory. When in use, several support modules 21 are connected in alignment according to the support height requirements to form a temporary support 20; when in use, the support module 21 is lifted by the lifting device 10 and placed on the movable corbel 13, and then the next support module 21 is lifted and connected in alignment with the support module 21 located on or on the movable corbel 13 to form a combined module, and the combined module is continued to be lifted and the support module 21 located at the bottom is placed on the movable corbel 13, and the above operations are repeated until the installation of the overall temporary support 20 is completed. The overall installation process is simpler and more efficient; the top-down installation method is adopted, which occupies a smaller area and can be applied to a small space; through the combination of support modules 21, it can be applied to different support height requirements and is more flexible; at the same time, the support modules 21 are connected in alignment, which is easy to install and disassemble, and convenient for turnover, reducing material waste and saving construction costs.

[0045] Furthermore, the lifting device 10 also includes a column 12, a rotating shaft 14 is provided in the middle of the column 12, and one end of the movable bracket 13 is connected to the rotating shaft 14, and can rotate around the rotating shaft 14 to be perpendicular to the column 12. When in use, a plurality of lifting devices 10 are arranged around a circle, and an area where the temporary support 20 is to be installed is formed inside. One end of the movable bracket 13 is hinged to the column 12, and when in use, the movable bracket 13 is rotated so that the other end thereof extends to the inner side of the area surrounded by the lifting device 10, and the lifting and temporary placement of the support module 21 are realized by cooperating with the hoisting mechanism 16.

[0046] Specifically, when the lifting mechanism 16 performs the lifting operation, the movable corbel 13 is retracted so that the size of the area surrounded by the lifting device 10 can accommodate the support module 21 to pass through; when the lifting mechanism 16 drives the support module 21 to a certain height, the movable corbel 13 is lowered to make it perpendicular to the column 12, and the support module 21 is placed on the movable corbel 13 through the lifting mechanism 16; when the lifting mechanism 16 lifts the next support module 21 and aligns it with the support module 21 on the movable corbel 13, the movable corbel 13 is opened. At this time, the overall weight of the combined module formed by the two support modules 21 is borne by the lifting mechanism 16, and the lifting mechanism 16 continues to lift the combined module upward to a height, lowers the movable corbel 13, and temporarily places the combined module on the movable corbel 13.

[0047] Furthermore, the present application also proposes a specific structure in which a movable bracket 13 is hingedly arranged on the column 12: Figure 2 As shown, the rotating shaft 14 is arranged on one side of the column 12 through a mounting seat, and is arranged in a horizontal direction as a whole; a position corresponding to the rotating shaft 14 of the column 12 is provided with a limit snap-in 15, and the movable corbel 13 is a plate-like structure, and its width is not greater than the corresponding width of the limit snap-in 15; the middle part of the movable corbel 13 is movably connected with the rotating shaft 14 and can rotate around the rotating shaft 14; when the movable corbel 13 rotates to be perpendicular to the column 12, one end thereof extends into the interior of the limit snap-in 15, and its upper end face abuts against the upper inner wall of the limit snap-in 15, so as to realize the engagement with the limit snap-in 15, so that the movable corbel 13 can only rotate upwards, but cannot continue to rotate downwards, so that the movable corbel 13 can be folded up and put down; preferably, a torsion spring is provided between the rotating shaft 14 and the movable corbel 13, and the two straight sections of the torsion spring are respectively fixed to the rotating shaft 14 and the movable corbel 13. When the movable corbel 13 is put down, the torsion spring is in a twisted state and is perpendicular to the column 12 under the load pressure of the support module 21; when the hoisting mechanism 16 continues to lift upwards, the pressure on the movable corbel 13 disappears, and the torsion spring drives the movable corbel 13 to automatically reset, providing enough space for the lifting of the support module 21. The torsion spring is a commercially available product, and its specific structure is not described here.

[0048] Furthermore, if Figure 3 As shown, the present application proposes a structure of a lifting device 10, including a base 11, a column 12, a lifting mechanism 16 and a movable bracket 13; the base 11 is arranged at the bottom of the column 12, and the column 12 is stably fixed at a set position on the ground to prevent it from tipping over; the lifting mechanism 16 is arranged at the top of the column 12, and includes a fall chain 162 and a driving device 161, and one end of the fall chain 162 is provided with a hook for connecting the hoisting object, and the fall chain 162 can be extended or shortened by the driving device 161 to achieve the lifting of the hoisting object; the movable bracket 13 is arranged in the middle of the column 12. At the same time, the support module 21 is provided with a lifting ear that matches the hook.

[0049] The main function of the above-mentioned support module 21 is to form a temporary support 20 through a counter-connection, and to bear the pressure load transmitted by its upper support structure. Therefore, its specific shape and structure can be set according to the needs, as long as it can meet the requirements of bearing capacity; in this embodiment, the support module 21 is formed into a whole by connecting a number of rod-shaped, strip-shaped or plate-shaped components, and the whole is square, and the lifting lugs are arranged in the middle of the vertical components at the four corners of the support module 21; correspondingly, the number of lifting devices 10 is four, which are respectively arranged corresponding to the positions of the lifting lugs, and a square area that can accommodate the support module 21 is formed to facilitate lifting the support module 21. In some other embodiments of the present application, the support module 21 can also be other shapes, and the lifting device 10 is arranged corresponding to the specific shape of the support module 21. Preferably, the support module 21 is made of commonly used construction materials, and has a simple structure and is easy to make.

[0050] Furthermore, the support module 21 includes a top module 22, a standard module 23 and a bottom module 24, which are connected in position by a connection flange 25; the connection flange 25 is respectively arranged at the bottom of the top module 22, the top and bottom of the standard module 23 and the top of the bottom module 24. The top module 22, the standard module 23 and the bottom module 24 are connected in position from top to bottom to form a temporary support 20, the top module 22 is located at the top of the temporary support 20, the bottom module 24 is located at the bottom of the temporary support 20, and the standard module 23 is located between the top module 22 and the bottom module 24, and the number of the standard modules 23 can be selectively set according to the requirements of the support height.

[0051] like Figure 4 As shown, the connecting flange 25 is a plate-like structure with a threaded hole. After the upper and lower support modules 21 are aligned, the connecting flanges 25 fit together and the threaded holes form a through hole. Preferably, the through hole is located on the outside of the outer edge of the support module 21, so that it is convenient to use a fastener to pass through the through hole, and then tighten it by bolts to achieve the alignment connection of the two support modules 21; the number of connecting flanges 25 is not limited here. Preferably, there are more than two connecting flanges 25 to make the connection of the support module 21 more stable.

[0052] Furthermore, since both the top module 22 and the standard module 23 need to be temporarily placed on the movable corbel 13 during the installation process, the bottom of the top module 22 and the standard module 23 are provided with a connecting piece 26 protruding in the circumferential direction thereof to overlap with the movable corbel 13.

[0053] Preferably, if Figure 4As shown, the connecting flanges 25 are arranged at the four corners of the bottom of the top module 22 and the top and bottom corners of the standard module 23. The connecting flanges 25 located at the bottom of the two extend outward by a sufficient length so that they can simultaneously connect the upper and lower support modules 21 and can overlap the movable corbels 13, so that the structure of the support module 21 is simpler and easier to manufacture.

[0054] Furthermore, the bottom of the bottom module 24 is also provided with an adjustable foot 40 for adjusting the height of the temporary support 20. When the temporary support 20 can fully contact the upper structure it supports, an effective support is formed. Specifically, the adjustable foot 40 can be in the form of a stud and a support threadedly connected to the stud or a hydraulic jack, etc., which is not limited here.

[0055] Furthermore, an adjustable pad 30 is provided on the top of the top module 22 to support the upper support structure. In a specific embodiment, the support module 21 is factory-customized and has fixed specifications; when the combination of the support module 21 and the adjustment of the adjustable support foot 40 cannot meet the support height requirement, the adjustable pad 30 is provided to make the temporary support 20 press against the upper structure.

[0056] The present application also provides a method for installing a modular temporary support device, which is used to install the modular temporary support device as described above. Figure 5 As shown, the following steps are included:

[0057] (1) Install the lifting device 10 at the set position and connect and fix them together;

[0058] By connecting the lifting devices 10 together, the stability of the lifting devices 10 can be improved, and the safety of its use can be improved; the specific connection method is not limited here, such as using a connecting rod to connect the columns 12 of two adjacent lifting devices 10 respectively.

[0059] (2) Connect the lifting mechanism 16 to the top module 22, lift the top module 22, and place it on the movable bracket 13;

[0060] Specifically, the hook of the fall chain 162 is connected to the lifting ear of the top module 22, and the driving device 161 is operated synchronously to make the top module 22 smoothly lifted to a height higher than the movable corbel 13, and then the movable corbel 13 is opened, and the top driving device 161 places the top module 22 on the movable corbel 13.

[0061] (3) lifting a standard module 23, aligning and connecting the standard module 23 and the top module 22 to form a combined module; lifting the combined module and placing it on the movable corbel 13;

[0062] Specifically, a standard module 23 is placed under the top module 22, the fall chain 162 is removed from the top module 22 and connected to the lifting lug of the standard module 23, and the driving device 161 is synchronously operated to smoothly lift the standard module 23 to the lower part of the top module 22, and the connecting flange 25 at the bottom of the top module 22 and the top of the standard module 23 are connected by bolts so that the two are aligned and connected together to form a combined module; the driving device 161 is continued to be operated, and at this time the connecting flange 25 at the bottom of the top module 22 is separated from the movable corbel 13, and the movable corbel 13 is automatically reset; after the combination is lifted to a height higher than the movable corbel 13, the corbel is lowered again so that the connecting flange 25 at the lower part of the standard module 23 overlaps the movable corbel 13.

[0063] In a specific embodiment, a plurality of standard modules 23 need to be arranged according to the support height requirement, and the installation of all standard modules 23 can be completed by repeating the method in this step.

[0064] (4) lifting the bottom module 24 and aligning and connecting the bottom module 24 and the standard module 23;

[0065] Specifically, the bottom module 24 is placed under the standard module 23, the fall chain 162 is removed from the standard module 23 and connected to the lifting lug of the bottom module 24, and the driving device 161 is synchronously operated to smoothly lift the bottom module 24 to the lower part of the standard module 23, and the connecting flange 25 at the bottom of the standard module 23 and the top of the bottom module 24 are bolted to connect the two so that they are aligned and connected together, thereby completing the alignment connection of the temporary support 20.

[0066] (5) Install the adjustable feet 40 on the bottom module 24 and lower the adjustable feet 40 to the ground;

[0067] Specifically, after the adjustable foot 40 is installed, the driving device 161 is first operated to lift the temporary support 20, so that the standard module 23 located above the bottom module 24 is separated from the movable corbel 13, so as to facilitate the folding of the movable corbel 13; then the driving device 161 is operated to lower the temporary support 20 to the ground, and the height of the adjustable foot 40 is adjusted so that the top module 22 is against the upper support structure.

[0068] In a specific embodiment, the support height is measured before installation, and the number of standard modules 23 that need to be installed is calculated based on the support height; when the support height does not match the height of the temporary support 20 after alignment and connection, and the adjustable feet 40 cannot meet the requirements, before installing the top module 22, an adjustable pad 30 is set on the top of the top module 22, and then the top module 22 and the adjustable pad 30 are lifted synchronously to ensure that after the temporary support 20 is fully installed, the adjustable feet 40 can be adjusted to make it press against the upper structure.

[0069] The present application also proposes a method for dismantling a modular temporary support device, which is used to dismantle the modular temporary support device as described above, comprising the following steps:

[0070] (1) Connect the lifting mechanism 16 to the bottom module 24. At this time, the weight of the temporary support 20 is borne by the lifting mechanism 16. Then remove the adjustable feet 40.

[0071] (2) lowering the temporary support 20 to the ground, releasing the connection between the bottom module 24 and the standard module 23 above it; lifting the combined module, and removing the bottom module 24;

[0072] Preferably, since the bottom module 24 has a certain weight, in order to facilitate its movement, after removing the adjustable bracket, a moving mechanism is set under the temporary support 20, and the temporary mechanism is placed on the moving mechanism through the lifting mechanism 16, so that the removed bottom module 24 is directly placed on the moving mechanism, making it more convenient to move;

[0073] In a specific embodiment, in order to improve the safety of the dismantling operation, after the connection between the bottom module 24 and the combined module above it is released, the combined module is temporarily placed on the movable corbel 13 .

[0074] (3) Repeat the previous operation to dismantle the standard module 23, lower the top module 22 to the ground, and remove the top module 22;
