Description

Technical Field

[0001] This utility model relates to the field of building structure accessories technology, and in particular to a high-strength column cap buffer protection component. Background Technology

[0002] Column capitals, as a common structural component, are widely used in construction, bridges, and large equipment support. Their main function is to connect the supporting column to the upper bearing plate or beam and effectively transfer loads. In practical applications, the top of the supporting column, in addition to bearing static pressure, is often subjected to dynamic impacts or sudden high-intensity loads. To protect the main structure and the supporting column itself from impact damage, existing column capitals usually integrate a buffer structure. These existing buffer structures are typically quite simple, such as a single-layer rubber buffer pad or spring inside the column capital. While this single buffer method is adequate for small impacts, it becomes insufficient when facing high... During a high-intensity impact, the pressure instantly concentrates in a localized area of ​​the buffer pad, failing to be effectively dispersed. This easily leads to the rapid failure or cracking of the buffer material due to excessive local stress, causing the impact force to act directly on the main structure and failing to provide effective protection. Furthermore, in terms of the installation and fixing of column caps and support columns, existing technologies typically use fixed sleeves or flanges that match the diameter of the support column for connection. This fixed-size connection method lacks flexibility. When it is necessary to install support columns of different diameters, column caps of the corresponding specifications must be replaced. This not only increases the variety and cost of spare parts inventory but also makes on-site installation and replacement work cumbersome and lacks versatility.

[0003] Therefore, this utility model proposes a high-strength column cap buffer protection component to overcome the shortcomings of the prior art. Utility Model Content

[0005] This utility model provides a high-strength column cap buffer protection assembly, including: a support plate, a fixing cover, a telescopic column one, a telescopic column two, a buffer plate one and a buffer two; and a protection adjustment mechanism.

[0006] Both the buffer plate one and the buffer two are provided with multiple honeycomb holes, and buffer pads are filled in the honeycomb holes; the protection adjustment mechanism includes a protective sleeve, an arc-shaped shell that can be detachably installed on the outer wall of the protective sleeve, and studs, rotating rings and fastening rings for locking the arc-shaped shell.

[0007] Furthermore, the first telescopic column and the second telescopic column are arranged vertically between the support plate and the first buffer plate, the protective adjustment mechanism is located at the bottom of the fixed cover, and the arc-shaped shell is used to encircle and fix the external support column.

[0008] Preferably, the support plate has fixing holes around its perimeter for fixing.

[0009] Preferably, the arc-shaped shell includes a connecting plate, and the inner wall of the connecting plate is provided with connecting posts and circular holes for mutual fitting and alignment.

[0010] Preferably, the arc-shaped shell is formed by splicing two separable half-shell structures, and the stud passes through the two half-shell structures.

[0011] Preferably, the rotating ring and the fastening ring are threaded onto the outer wall of the stud to tighten or loosen the arc-shaped shell.

[0012] Preferably, the cushioning pad is made of elastic rubber or polyurethane material.

[0014] Preferably, the honeycomb holes are through holes that penetrate the thickness direction of the first buffer plate and the second buffer plate.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem that the existing column cap buffer structure is simple and easily causes stress concentration and local cracking when subjected to high-intensity pressure.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0026] Example:

[0027] Please refer to Figures 1 to 4 As shown, the high-strength column cap buffer protection assembly is installed on the top of the support column 4. The overall structural frame of the assembly includes a support plate 1 that serves as the top bearing surface. Multiple fixing holes 5 are evenly distributed around the perimeter of the support plate 1. These fixing holes 5 are used to install and fix the entire assembly to the external equipment using bolts or rivets. A downwardly extending hollow fixing cover 3 is fixedly connected to the center of the bottom surface of the support plate 1 by welding or integral molding. The interior of the fixing cover 3 forms a cavity for accommodating a multi-stage buffer system. A protective adjustment mechanism 2 is connected to the bottom of the fixing cover 3. (Refer to...) Figure 3The multi-stage buffer system set inside the fixed cover 3 includes telescopic column 6, telescopic column 7, buffer plate 8, and buffer 9. Telescopic column 6 and telescopic column 7 are telescopic sleeve structures or micro hydraulic damping columns with built-in springs. The top of telescopic column 6 and telescopic column 7 abuts against the bottom surface of the support plate 1, and the bottom abuts against the top surface of buffer plate 8. They are used to provide initial elastic or damping buffering of vertical impact force. Buffer plate 8 and buffer 9 are stacked tightly vertically and are located below telescopic column 6 and telescopic column 7. Buffer plate 8 and buffer 9 are densely provided with multiple honeycomb holes 10. The honeycomb holes 10 are through holes that penetrate the thickness of buffer plate 8 and buffer 9. Each honeycomb hole 10 is filled with a replaceable buffer pad 11. The buffer pad 11 is made of high elastic rubber or polyurethane foam material. The structure of the honeycomb holes 10 and the buffer pad 11 work together to effectively disperse the pressure after initial buffering and perform secondary flexible absorption.

[0028] Please refer to Figure 1 , Figure 2 and Figure 4 The protective adjustment mechanism 2 includes a protective sleeve 201 serving as a connecting base. The protective sleeve 201 is fixedly connected to the lower opening of the fixed cover 3 by means of threads or snap-fit. The protective adjustment mechanism 2 also includes a detachable arc-shaped shell 202, which is composed of two separable half-shell structures spliced ​​together. When the two half-shell structures are closed, they form an inner cavity that can encircle the support column 4. The outer wall of the arc-shaped shell 202 is slidably fitted or snap-fitted to the outer surface of the protective sleeve 201. To ensure that the two half-shell structures can be accurately aligned when closed, each half-shell structure has a connecting plate 205 on its splicing surface. One connecting plate 205 has a protruding connecting column 204, and the other connecting plate 205 has a corresponding connecting column 204 for... The circular hole 203 accommodates the connecting post 204. Through the insertion and engagement of the connecting post 204 and the circular hole 203, the arc-shaped shell 202 can be quickly aligned. In order to lock the arc-shaped shell 202, an integrally formed lug is provided on the arc-shaped shell 202. The lug has a through hole. The stud 206 passes through the lug corresponding to the two half-shell structures. The rotating ring 207 and the fastening ring 208 are screwed together on the outer wall of the stud 206 through internal threads. By tightening the rotating ring 207, the rotating ring 207 and the fastening ring 208 can be driven to move axially along the stud 206, thereby tightening the two half-shell structures and making them firmly clamp the support post 4. This clamp-type fastening structure ensures that the component can easily adapt to support posts 4 with different outer diameters and provide reliable radial protection.

[0029] As a preferred embodiment, in order to improve the installation stability and reliability of the entire component, multiple fixing holes 5 are evenly provided around the perimeter of the support plate 1. The fixing holes 5 are used to firmly fix the support plate 1 to the surface of the equipment to be installed by bolts, thereby ensuring that the entire high-strength column cap buffer protection component will not be displaced when subjected to huge impact forces.

[0030] As a preferred embodiment, in order to ensure that the arc-shaped shell 202 can be quickly and accurately aligned when closed, the arc-shaped shell 202 is composed of two separable half-shell structures spliced ​​together. The mating surfaces of the two half-shell structures are provided with integrally formed connecting plates 205. One connecting plate 205 is provided with a protruding connecting post 204, while the other connecting plate 205 is provided with a corresponding circular hole 203 for accommodating the connecting post 204. During assembly, the connecting post 204 is inserted into the circular hole 203, realizing the guidance and positioning of the two half-shell structures.

[0031] In a preferred embodiment, in order to lock and unlock the arc-shaped shell 202, the rotating ring 207 and the fastening ring 208 are screwed together on the outer wall of the stud 206 through internal threads. The outer surface of the rotating ring 207 is provided with a knurled or polygonal structure, which facilitates manual or tool-assisted rotation. By rotating the rotating ring 207, the fastening ring 208 can be moved along the axial direction of the stud 206, thereby tightening or loosening the arc-shaped shell 202.

[0032] As a preferred embodiment, in order to further improve the cushioning effect and service life, the cushioning pad 11 is preferably made of closed-cell polyurethane foam or silicone rubber material with a moderate elastic modulus. This material has excellent resistance to compression deformation and aging resistance.

[0033] As a preferred embodiment, in order to make the effect of the initial buffering stage more stable and controllable, the first telescopic column 6 and the second telescopic column 7 are preferably spring buffer columns with pre-tension or small one-way hydraulic damping columns, which can absorb instantaneous impact energy and avoid rigid collisions.

[0034] In a preferred embodiment, in order to maximize the stress dispersion effect of the buffer plate, the honeycomb holes 10 are regular hexagonal through holes that penetrate the thickness direction of the first buffer plate 8 and the second buffer plate 9, and are evenly arranged. At the same time, the first buffer plate 8 and the second buffer plate 9 are stacked and fixed together vertically by positioning pins or adhesives to form an integral buffer unit.

[0035] Working principle:

[0036] In use, firstly, the entire assembly is fixed to the external equipment using bolts through the fixing holes 5 around the support plate 1. Then, the support column 4 is installed. The installation and adjustment process involves the operator rotating the rotating ring 207 on the protection adjustment mechanism 2 counterclockwise, causing the rotating ring 207 and the fastening ring 208 to unscrew outwards along the external thread of the stud 206, thereby loosening the locking force on the arc-shaped shell 202. At this point, the two separable half-shell structures constituting the arc-shaped shell 202 can be opened to both sides. After placing the support column 4 to be installed between the two half-shell structures, the two half-shell structures are then reassembled. During the closing process, the connecting post 204 on the connecting plate 205 of one half of the shell structure is inserted into the circular hole 203 on the connecting plate 205 of the other half of the shell structure. The insertion and engagement of the connecting post 204 and the circular hole 203 achieves guiding alignment, ensuring that the arc-shaped shell 202 accurately surrounds the support column 4. Then, the rotating ring 207 is rotated clockwise, causing the rotating ring 207 and the fastening ring 208 to screw inward along the stud 206, thereby firmly tightening the two half-shell structures and completing the clamping and fixing of the support column 4. The entire protective adjustment mechanism 2 uses the protective sleeve 201 as the connecting base. The openable and fastening design of the arc-shaped shell 202 enables wide compatibility and convenient installation of support columns 4 with different diameters. After installation, the high-strength column cap buffer protection assembly enters the pressure-bearing working state. When the top surface of the support plate 1 is subjected to vertical impact pressure from above, the pressure is first transmitted to the telescopic columns 6 and 7 located inside the fixed cover 3 and whose tops abut against the bottom of the support plate 1. The telescopic columns 6 and 7, acting as spring buffer columns or hydraulic damping columns, will undergo compression deformation to initially absorb and buffer the impact energy. The remaining pressure after the initial buffering continues to be transmitted downwards to the upper... On the stacked buffer plates 8 and 9, multiple honeycomb holes 10 are densely arranged on the buffer plates 8 and 9. The pressure is evenly distributed along the structural wall of the honeycomb holes 10, avoiding stress concentration in local areas. At the same time, the buffer pads 11 filled inside each honeycomb hole 10 are compressed and undergo elastic deformation, which absorbs the dispersed pressure in a secondary flexible manner. Through the synergistic effect of the multi-level buffer system formed by the telescopic column, the honeycomb holes 10 and the buffer pads 11, the high-intensity impact force can be effectively dissipated, thereby protecting the safety and stability of the support column 4 and the upper structure.
