Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a beam bottom support device that can be quickly installed and disassembled. Background Technology

[0002] Beam bottom support usually refers to the temporary or permanent structure used to support the bottom of a beam during the construction of a building or bridge, in order to ensure the stability and safety of the beam during the construction or use phase. This support system can include scaffolds, formwork, support columns or jacks, etc.

[0003] Traditional beam-bottom support structures often use spliced ​​rigid supports. When bearing heavy objects, the stress is concentrated and lacks elastic adjustment capabilities, which can easily lead to bending or breakage of the support structure due to overloading, thereby affecting construction safety and structural stability.

[0004] In addition, such rigid supports are usually unable to sense load changes in real time, lack effective overload protection functions, and cannot actively adjust or distribute loads under extreme stress conditions, resulting in reduced overall structural reliability and significant safety hazards during construction. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the tendency of traditional rigid supports to bend and fail, lack of overload protection, impact on safety and stability, and the need to optimize and improve load-bearing and adjustment capabilities.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a beam bottom support device that can be quickly installed and disassembled, comprising a support column, and further comprising: an upper support assembly fixed to the upper part of the support column; a lower support assembly fixed to the lower part of the support column, wherein the lower support assembly includes a support seat for placement on the ground, a hydraulic rod slidably mounted on the upper part of the support seat and fixedly mounted on the support column, and a cavity for placing hydraulic oil is provided between the support seat and the support column; a hydraulic control assembly fixed to one side of the support seat, the hydraulic control assembly communicating with the cavity, wherein when the upper support assembly carries an overweight object, the hydraulic rod is forced downward and slowly releases the hydraulic oil in the cavity into the hydraulic control assembly.

[0007] In at least some embodiments, a screw hole is provided on the side of the hydraulic rod away from the support base, the support column is screwed to the hydraulic rod, a guide rod is fixedly connected to the outside of the hydraulic rod, and the hydraulic rod is slidably mounted on the upper part of the support base through the guide rod. The upper support assembly and the lower support assembly have the same structure.

[0008] In at least some embodiments, the hydraulic control assembly includes a storage tank fixed to one side of the support base. Multiple storage tanks are provided and are evenly arranged circumferentially outside the support base. The hydraulic pressure inside each storage tank is adjustable to adapt to the current operating load intensity.

[0009] In at least some embodiments, a first piston plate is provided inside the storage tank, and the lower part of the first piston plate is connected to a second piston plate slidably installed inside the storage tank by a helical spring. When the cavity transmits hydraulic oil to the storage tank, the second piston plate moves upward under force.

[0010] In at least some embodiments, a lead screw is rotatably mounted on the upper part of the storage tank, and a first piston plate slidably mounted inside the storage tank is screwed to the lead screw. The upper part of the lead screw extends through the storage tank to the outside and is fixedly connected to a turntable. A central channel through which the lead screw can pass is opened in the middle of the second piston plate. When the second piston plate moves upward, the lead screw is movably inserted into the central channel. The storage tank has a transmission channel that communicates with the support cavity.

[0011] In at least some embodiments, the beam bottom support device further includes an auxiliary support assembly. The auxiliary support assembly includes a base plate fixed to the outside of the support base. Multiple base plates are arranged in a circumferentially uniform array outside the support base. Each base plate has a groove on its outside. A support plate is slidably installed inside the groove of the base plate. When the connection between the support plate and the base plate slides to the bottom, a spring clip fixed in the inner wall of the base plate retracts and pushes out, thus limiting the position of the support plate.

[0012] In at least some embodiments, a central pad is fixedly connected to the lower center of the support base, and a first edge pad is fixedly connected to the lower edge support leg of the support base. The support plate is bent, and a second edge pad is fixedly connected to the bottom bend of the support plate. When stored, the connection between the support plate and the base plate moves to the highest point of the slide groove, the main body of the support plate fits into the slide groove, and the spring clip presses against the support plate to perform another limiting action.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0014] 1. In this invention, efficient buffering and load-bearing safety are achieved through hydraulic buffering, preventing overload fracture of the support column; multiple independently adjustable storage tanks distributed circumferentially achieve adaptive leveling and anti-eccentric load, and uneven loads are automatically balanced by hydraulic pressure; a mechanical self-locking structure with sliding grooves and spring clips and a threaded connection hydraulic rod design are adopted, allowing the support plate to be unfolded and locked with one click and the hydraulic rod to be tightened quickly, achieving rapid disassembly and convenient storage; the triangular support layout of the central pad, edge pads and auxiliary support plates enhances structural stability and expands the bearing area to cope with large-span beam support; and the screw adjustment mechanism in the storage tank flexibly changes the spring preload to achieve adjustable load-bearing capacity, thereby comprehensively solving the problems of stress concentration and adjustment difficulties of traditional rigid supports, and combining safety, adaptability and construction efficiency.

[0025] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example, according to Figures 1-6 ,like Figure 1 As shown in the figure, an embodiment of the present invention provides a beam bottom support device that can be quickly installed and disassembled, including a support column 2, and further including: an upper support assembly 3 fixed to the upper part of the support column 2; and a lower support assembly 1 fixed to the lower part of the support column 2, wherein the lower support assembly 1 includes a support seat 101 for placing on the ground, and a hydraulic rod 102 slidably installed on the upper part of the support seat 101 to fix the support column 2, and a cavity for placing hydraulic oil is left between the support seat 101 and the support column 2; when installing the device, firstly, the support seat 101 is accurately positioned to the ground bearing point, and then... Adjusting the verticality of the support column 2 ensures that the axis of the device coincides with the load direction. The upper support component 3 forms a three-dimensional pressure distribution with the bottom surface of the beam through the adaptive leveling mechanism, avoiding the local stress concentration phenomenon of traditional rigid support. The hydraulic control component 5 is fixed on one side of the support seat 101 and is connected to the cavity. At this time, the hydraulic control component 5 and the cavity are pre-filled with high viscosity anti-pressure hydraulic oil and an initial pressure balance is established. When the upper support component 3 carries an overweight object, the hydraulic rod 102 is forced to move downward and slowly releases the hydraulic oil in the cavity into the hydraulic control component 5.

[0028] Specifically, when the beam load increases, the upper support assembly 3 transmits pressure to the support column 2, pushing the hydraulic rod 102 to slowly move down along the inner wall of the support seat 101. The cavity volume shrinks, forcing the hydraulic oil to generate flow resistance, thus forming a gradual buffer.

[0029] In this embodiment, a screw hole 104 is provided on the side of the hydraulic rod 102 away from the support base 101. The support column 2 is screwed to the hydraulic rod 102. During installation, the screw hole 104 of the hydraulic rod 102 is threadedly connected to the bottom end of the support column 2 and tightened to ensure the precise fit between the guide rod 103 and the support base 101. The guide rod 103 is fixedly connected to the outside of the hydraulic rod 102. The hydraulic rod 102 is slidably installed on the upper part of the support base 101 through the guide rod 103. When bearing load, the beam load is transmitted to the support column 2 through the upper support assembly 3. The hydraulic rod 102 is pressed down by the threaded connection, and the guide rod 103 slides smoothly along the support base 101 to ensure vertical force. The upper support assembly 3 and the lower support assembly 1 have the same structure.

[0030] In this embodiment, the hydraulic control component 5 includes a storage tank 501 fixed to one side of the support base 101. Multiple storage tanks 501 are provided and are evenly arranged around the outside of the support base 101. The hydraulic pressure inside the storage tanks 501 is adjustable to adapt to the current working load intensity. The multiple storage tanks 501 are evenly fixed around the outside of the support base 101 to form a ring hydraulic buffer system.

[0031] The storage tank 501 is equipped with a first piston plate 504. The lower part of the first piston plate 504 is connected to a second piston plate 506 that is slidably installed inside the storage tank 501 via a helical spring 505. When the cavity transmits hydraulic oil to the storage tank 501, the second piston plate 506 moves upward under force.

[0032] When the support column 2 bears a load, the hydraulic oil in the cavity is forced into the storage tank 501. Within the normal load range, the hydraulic oil slowly enters the storage tank 501, and the second piston plate 506 moves smoothly upward under the action of oil pressure, compressing the helical spring 505 to store elastic potential energy; when the load is reduced, the spring releases energy to push the second piston plate 506 downward, pressing the hydraulic oil back into the cavity to complete the automatic reset.

[0033] The coordinated operation of multiple storage tanks 501 can adapt to load changes in different directions: when there is an off-center load, the storage tank 501 on the side of the load will receive more hydraulic oil, and adaptive balance is achieved by the independent operation of each tank.

[0034] In this embodiment, a lead screw 502 is rotatably mounted on the upper part of the storage tank 501. A first piston plate 504, which is slidably mounted inside the storage tank 501, is screwed to the lead screw 502. The upper part of the lead screw 502 extends through the storage tank 501 to the outside and is fixedly connected to a turntable 503. The operator drives the lead screw 502 to rotate by rotating the turntable 503. Since the first piston plate 504 is threadedly engaged with the lead screw 502 and is restricted from circumferential rotation, the rotation of the lead screw 502 will drive the first piston plate 504 to move up and down along the inner wall of the storage tank 501, thereby changing the initial compression of the helical spring 505 and realizing the preset adjustment of the system's load-bearing capacity.

[0035] The second piston plate 506 has a central channel 507 through which the lead screw 502 can pass. When the second piston plate 506 moves upward, the lead screw 502 movably inserts into the central channel 507. The storage tank 501 has a transmission channel 508 that communicates with the cavity of the support base 101. The inner diameter of the central channel 507 of the second piston plate 506 is slightly larger than the outer diameter of the lead screw 502. When the hydraulic oil pushes the second piston plate 506 upward, the lead screw 502 acts as a fixed guide shaft through the channel without causing mechanical interference, ensuring that the piston plate moves in a straight line. This prevents the adjustment mechanism of the lead screw 502 from interfering with the piston buffer system. During adjustment, the lead screw 502 drives the first piston plate 504 to change the spring preload. During operation, the second piston plate 506 can slide freely, and the hydraulic oil circulates between the cavity and the storage tank 501 through the transmission channel 508.

[0036] In this embodiment, the auxiliary support component 4 of the beam bottom support device achieves dynamic support and self-locking functions through the collaboration of multiple components: its core is composed of multiple base plates 401 that are uniformly fixed to the outside of the support base 101 in the circumferential direction, and each base plate 401 has a sliding groove 402 on its outer side with a vertically sliding support plate 403 embedded in it.

[0037] Specifically, the beam bottom support device also includes an auxiliary support assembly 4. The auxiliary support assembly 4 includes a base plate 401 fixed to the outside of the support base 101. Multiple base plates 401 are arranged in a uniform array around the outside of the support base 101. Each base plate 401 has a groove 402 on its outside. A support plate 403 is slidably installed inside the groove 402 of the base plate 401. When the connection between the support plate 403 and the base plate 401 slides to the bottom, the spring clip 404 fixed in the inner wall of the base plate 401 retracts and pushes out, limiting the support plate 403. Then, when the support plate 403 is moved down by the beam pressure, it slides down along the groove 402 to the preset lowest position, usually completely fitting the contact surface. At this time, the spring clip 404 pre-installed in the inner wall of the base plate 401 is mechanically deformed due to the displacement of the support plate 403, and quickly retracts and releases the elastic force to pop out radially, locking into the limiting groove on the side wall of the support plate 403 or abutting its bottom surface to form a rigid stop.

[0038] The process achieves automatic locking through the elastic deformation and reset mechanism of the spring clip 404, which not only ensures that the support plate 403 maintains a stable support posture under load conditions and prevents retraction failure, but also allows manual pressing of the spring clip 404 to release the limit after unloading, facilitating the reset of the support plate 403.

[0039] In this embodiment, the support base 101 of the beam bottom support device achieves stable load-bearing and convenient storage through multi-level pads and an adjustable support structure. Specifically, a central pad 6 is fixedly connected to the lower center of the support base 101, and a first edge pad 7 is fixedly connected to the lower edge support leg of the support base 101. The central pad 6 fixedly connected to the lower center of the support base 101 serves as the main bearing surface, directly transferring the vertical load to the foundation, while the first edge pad 7 at the edge support leg enhances the anti-overturning capacity.

[0040] The support plate 403 is bent, and a second edge pad 8 is fixedly connected to the bent part of the bottom of the support plate 403. The support plate 403 adopts a bent design, and the second edge pad 8 extending from the bottom forms a triangular support layout with the first edge pad 7 in the unfolded state, which expands the bottom contact area to distribute pressure. When stored, the connection between the support plate 403 and the base plate 401 moves to the highest point of the slide groove 402. The main body of the support plate 403 is fitted into the slide groove 402, and the spring clip 404 presses against the support plate 403 to perform another limiting action. Specifically, the support plate 403 slides up the slide groove 402 of the base plate 401 to the highest position, and its bent section is completely embedded in the slide groove 402. At this time, the spring clip 404 is deformed by pressure and is locked into the corresponding groove of the support plate 403, realizing double limiting. The slide groove 402 structure constrains the lateral displacement, and the spring clip 404 is used to fix the vertical position by elastic pressing, ensuring stable storage.

[0041] The working principle of this invention is as follows:

[0042] The support column 2 is threadedly connected to the hydraulic rod 102, which slides within the support base 101. The cavity is pre-filled with high-viscosity hydraulic oil. When the load on the beam increases, the hydraulic rod 102 presses down, and the hydraulic oil is squeezed into the circumferentially distributed storage tanks 501, pushing the second piston plate 506 to compress the spiral spring 505 to store energy, forming a gradual buffer. When the load decreases, the spring rebounds and pushes the piston plate to press the oil back into the cavity, achieving automatic reset. The initial pressure of multiple storage tanks 501 can be independently adjusted to adapt to off-center load conditions, solving the overload bending problem in the background technology. The base plate 401 on the outer periphery of the support base 101 is embedded with a sliding support plate 403. When unfolded, the support plate 403 slides down to the working position, and the spring clip 404 pops out and locks it. The second edge pad 8 at its bottom and the first edge pad 7 of the support base 101 form a triangular support to distribute the pressure. When stored, the support plate 403 slides up to the top of the slide groove 402, and the spring clip 404 locks it again to ensure compact storage.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
