[0002] In engineering construction, building temporary residences for workers and warehouses for storing items is an indispensable project. Generally, temporary residences for workers and warehouses for storing items are built on flat ground. However, in some areas where flat land cannot meet the construction needs, it is necessary to build a platform as the ground foundation of the temporary building. The platform is a carrier for personnel and equipment, and its structure needs to be stable and reliable to ensure the safety of personnel and equipment.

[0003] At present, in engineering construction, the following problems often exist in the construction and use of platforms. Since the foundation of the temporary platform in the area cannot be fully hardened, the support will sink more or less during the use of the platform. Once the sinking occurs, it will cause the pressure imbalance of multiple support columns. In continuous use, it will cause deformation of steel structure components, affecting secondary use. At the same time, there are also hidden dangers of unsafety. Therefore, it is necessary to invent a support that can prevent sinking. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0020] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1-Figure 7 As shown, a preassembled umbrella-shaped support column includes a support rod 1, one end of the support rod 1 is provided with a mounting groove, and an umbrella-shaped support 2 is matched in the mounting groove. The support rod 1 is a hollow pipe pile, and a docking groove is provided at its end for docking with the end of the pre-assembled umbrella-shaped support 2 to form a whole, and also includes an umbrella rib assembly 4, and multiple umbrella rib assemblies 4 are arranged in an inverted umbrella shape around the umbrella-shaped support 2 for auxiliary support; the connection end of the entire support column and the bottom surface of the platform is in an inverted umbrella shape, which increases the support force surface and allows the pressure generated by the platform to be better transmitted to the support rod 1.

[0021] The rib mounting plate 3 is fixed on the side of the umbrella-shaped support 2 and is used to install multiple rib assemblies 4. The umbrella-shaped support 2 is provided with slots for accommodating the rib assemblies 4 on all sides, and the rib mounting plate 3 is fixedly welded on both sides of the slots.

[0022] The settlement compensation assembly 5 is arranged at the center of the umbrella-shaped support 2, and is provided with a pre-pressure device for compensating the settlement of the support rod 1. A pressure device is provided in the settlement compensation assembly 5, and the device is in a compressed state under normal conditions. When the support rod 1 settles, the device is triggered to release the pressure to cope with the situation where the support force of the support rod 1 on the platform is reduced due to the settlement of the support rod 1.

[0023] As an embodiment of the present invention, Figure 1-3 As shown: the umbrella-shaped support 2 includes a support body 21 flange-connected to the support rod 1, a connecting protrusion 22 is provided at the bottom of the support body 21, and the connecting protrusion 22 is engaged with the support rod 1 to limit the position, the connecting protrusion 22 is used to enhance the connection strength between the support body 21 and the support rod 1, and a fixing bolt 23 for fixing the support rod 1 and the umbrella-shaped support 2 is provided on the connecting protrusion 22.

[0024] As an embodiment of the present invention, Figure 3-4As shown, the rib assembly 4 includes an rib plate 41 for auxiliary support, the bottom of the rib plate 41 is rotatably matched with a rotating shaft 43, and the rib plate 41 is rotatably matched with the rib mounting plate 3 through the rotating shaft 43. Four rib plates 41 are symmetrically arranged in pairs, and their bottoms rotate around the rotating shaft 43. The matching part of the rib plate 41 and the rib mounting plate 3 is provided with a torsion spring 44 for folding the rib plate 41, and the top of the rib plate 41 is hinged with a hinge support 42. The torsion spring 44 is provided to make the multiple rib plates 41 have a torsion force to deflect in the middle, and can provide an upward pushing stress when working.

[0025] During specific operation, after the support rod 1 and the umbrella-shaped support 2 are installed, the hinged ends of the multiple umbrella rib assemblies 4 arranged on the umbrella-shaped support 2 are respectively fixed to the platform to be built, and the multiple umbrella rib assemblies 4 are unfolded at a certain angle to maintain a stable state. In this process, the settlement compensation assembly 5 plays a major load-bearing role. The multiple umbrella rib assemblies 4 assist the settlement compensation assembly 5 in bearing the load under the torsion of the torsion spring 44. When the support rod 1 itself settles, the supporting force of the settlement compensation assembly 5 on the platform is reduced, and the settlement compensation assembly 5 settles downward with the support rod 1. At this time, the multiple umbrella rib assemblies 4 gather toward the center to jointly bear the load, so that the support at this point of the platform still maintains a relatively stable height, avoiding slow deformation and damage to the overall structure.

[0026] As an embodiment of the present invention, Figure 5-6 As shown, the settlement compensation component 5 includes a sliding groove 54 fixed at the center position of the upper end surface of the umbrella-shaped support 2, a sliding top block 51 is slidably fitted in the sliding groove 54, and a compression spring 52 is provided between the bottom of the sliding top block 51 and the sliding groove 54.

[0027] As an embodiment of the present invention, Figure 3 As shown: an elastic touch plate 53 for load balancing is provided at the top of the sliding top block 51. The settlement compensation component 5 bears the main load, and the elastic release of the settlement compensation component 5 and the platform is achieved through the elastic touch plate 53, thereby enhancing the impact resistance of the supporting overall structure and reducing the influence of the platform vibration on the supporting structure.

[0028] As an embodiment of the present invention, as shown in the figure: it also includes a limit assembly 6, which is arranged between the bottom of the umbrella rib plate 41 and the sliding top block 51, and is used to limit the sliding top block 51 and control the pressure released. A compression spring 52 is arranged between the sliding top block 51 and the sliding groove 54. The compression spring 52 is compressed before installation and is limited and fixed by the limit assembly 6. When the support rod 1 sinks, the sinking amplitude is too large, which causes the umbrella rib assembly 4 to fail, then the limit assembly 6 is controlled to release the elastic force of the compression spring 52, thereby reducing the damage to the overall structure of the platform when the support rod 1 sinks.

[0029] As an embodiment of the present invention, Figure 5-6 As shown: a notch for installing the limiting assembly 6 is provided at the bottom of the rib plate 41, a rectangular groove is provided at the position corresponding to the notch of the rib plate 41, and a limiting groove 61 is provided at the position corresponding to the rectangular groove of the sliding top block 51, and the limiting assembly 6 includes an anti-slip bushing 63 fixedly sleeved on the inner wall of the rectangular groove, and the anti-slip bushing 63 is slidably matched with the limiting tooth 62, and the function of the anti-slip bushing 63 is to increase the friction between the limiting tooth 62 and the side wall, so that the state of the limiting tooth 62 is not easy to change, and the stability of the switch structure is increased. A fixed pull rod 64 is provided at one end of the limiting tooth 62, and the fixed pull rod 64 and the rib plate 41 are a matching mechanism, and an adjusting nut 65 is provided at one end of the fixed pull rod 64 passing through the rib plate 41. The limiting groove 61 serves as a lock buckle for limiting the sliding top block 51, and the limiting tooth 62 is a sliding lock tooth, and the sliding top block 51 is limited by the limiting tooth 62.

[0030] When the rib assembly 4 is installed on the bottom of the platform, the compression spring 52 is compressed, and the support spring 66 is compressed and the limit tooth 62 is pushed to engage with the limit groove 61 by adjusting the adjusting nut 65, so that the sliding top block 51 is locked. When the support rod 1 sinks by itself, the support force of the settlement compensation component 5 at its top on the platform is reduced. At this time, the rib plate 41 continues to deflect toward the center under the action of the torsion spring 44 to compensate for the lack of support force. During the deflection of the rib plate 41, the bottom of the rib plate 41 rotates around the rotating shaft 43, thereby gradually pulling the fixed pull rod 64 outward. When the settlement of the support rod 1 exceeds a certain limit, the deflection angle of the rib plate 41 is too large, which will pull the limit tooth 62 to separate from the limit groove 61. At this time, the pressure accumulated in the elastic touch plate 53 is released, thereby pushing the sliding top block 51 to support the platform and slowing down the further deterioration of the situation.

[0031] During specific operation, as shown in the limit assembly 6 in the figure, the contact point between the limit groove 61 and the limit tooth 62 is provided with an inclined surface. When the support rod 1 is pressed down by gravity and sinks, the sliding top block 51 and the umbrella rib assembly 4 are both in a downwardly pressed state. When the sliding top block 51 is pressed and moved, the inclined surface of the limit groove 61 squeezes the limit tooth 62, causing the limit tooth 62 to retract. When the limit tooth 62 is fully retracted, it remains in a retracted state under the action of the anti-slip bushing 63. At this time, the elastic force of the compression spring 52 is completely released to counteract the pressure, thereby slowing down the settlement of the support column at that location, thereby achieving the purpose of protecting the platform structure.

[0032] Working principle: When the support rod 1 itself sinks slightly, multiple rib assemblies 4 assist the settlement compensation assembly 5 to bear the load under the torsion of the torsion spring 44. When the support rod 1 itself sinks, the supporting force of the settlement compensation assembly 5 on the platform is reduced, and the settlement compensation assembly 5 sinks downward with the support rod 1. At this time, multiple rib assemblies 4 gather toward the center to bear the load together, so that the support of the platform at this point still maintains a relatively stable height, avoiding slow deformation and damage of the overall structure.

[0033] When the settlement amplitude of the support rod 1 itself increases, the support force of the settlement compensation component 5 at its top on the platform decreases. At this time, the rib plate 41 continues to deflect toward the center under the action of the torsion spring 44 to compensate for the lack of support force. During the deflection of the rib plate 41, the bottom of the rib plate 41 rotates around the rotating shaft 43, thereby gradually pulling the fixed pull rod 64 outward. When the settlement of the support rod 1 exceeds a certain limit, the deflection angle of the rib plate 41 is too large, which will pull the limit tooth 62 to separate from the limit groove 61. At this time, the pressure accumulated in the elastic touch plate 53 is released, thereby pushing the sliding top block 51 to support the platform and slow down the further deterioration of the situation.

[0034] When the support rod 1 is compressed and sinks as a whole, the sliding top block 51 and the umbrella rib assembly 4 are both in a state of being pressed downward. When the sliding top block 51 is pressed and moved downward, the inclined surface of the limiting groove 61 squeezes the limiting tooth 62, causing the limiting tooth 62 to retract. When the limiting tooth 62 is fully retracted, it remains in a retracted state under the action of the anti-slip bushing 63. At this time, the elastic force of the compression spring 52 is completely released to resist the pressure, thereby slowing down the settlement of the support column at that location, thereby achieving the purpose of protecting the platform structure.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
