Description

Technical Field

[0001] This invention relates to the field of building column anti-collision technology, specifically to a prefabricated column with protective devices for impact and earthquake resistance. Background Technology

[0002] In the context of new industrialization, the use of prefabricated assembly construction methods for buildings and bridges has been vigorously developed and promoted. Prefabricated engineering structures need to withstand numerous loads during their service life, with seismic loads being one of the primary considerations. The impact loads that buildings may experience vary depending on the site environment. For example, in mountainous areas, buildings and bridges may be impacted by falling rocks, rolling stones, and debris flows; buildings and bridges near roads may be impacted by vehicles; and urban buildings may be affected by indoor natural gas explosions. Particular consideration is given to the fact that earthquakes in mountainous areas can easily trigger secondary disasters such as debris flows, causing earthquake-damaged structures to suffer further impact loads. With the rapid development of prefabricated construction, many important buildings and bridges face the risk of structural collapse due to component failure when prefabricated frame columns and piers, which are crucial load-bearing components, are subjected to sudden impact loads, posing a significant safety hazard. Therefore, installing protective devices on building columns and bridge piers is particularly important.

[0003] Not only do buildings and bridges require impact-resistant protective devices, but onshore and offshore wind turbine columns and offshore platforms also need such devices. Onshore wind turbine columns are subjected to wind loads, earthquake impacts, and foreign object impacts; offshore wind turbine columns are subjected to sea ice impacts, ship collisions, wind load impacts, earthquake impacts, and impacts from marine organisms; and offshore platforms are subjected to sea ice, ship impacts, and earthquake impacts. Prefabricated columns can be used for onshore and offshore wind turbine columns and offshore platforms. These columns are prefabricated in a factory, transported to the site by large transport vehicles, and quickly installed using cranes. Their connection points are specially designed to ensure the integrity and stability of the structure and facilitate later maintenance.

[0004] Protective devices are already being used on bridges and wind turbine columns. Chinese patent (publication number CN118911082A) discloses a collision protection device for bridge piers on water, comprising multiple sets of collision protection units, which are fitted onto the piers and provide protection. The units are arranged vertically. Each collision protection unit includes a support sleeve fitted onto the pier, with multiple support plates rotatably mounted on the outer wall of the sleeve. Each support plate has a rotatably mounted collision protection plate. The support sleeve also includes a synchronization structure and a buffer structure. The synchronization structure enables the multiple support plates to move synchronously, and the buffer structure provides a cushioning effect. Existing protective devices are ring-shaped structures, entirely fitted onto the outside of the bridge pier, using a mechanical structure for cushioning and collision protection. However, these devices have poor energy absorption and are difficult to use in the event of mechanical failure, easily leading to pier damage. They are also costly to manufacture. Furthermore, after damage from an impact, the entire protective device needs to be replaced, resulting in high replacement costs, difficulty in disassembly and installation, and an inability to achieve rapid replacement. Therefore, the existing technology needs further improvement. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to propose an impact-resistant and earthquake-resistant prefabricated column with a protective device, which solves the problems of poor energy absorption effect of existing protective devices, easy damage to the pier, need for complete replacement after impact damage, high replacement cost, difficulty in disassembly and installation, and inability to achieve rapid replacement.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An impact- and seismic-resistant prefabricated column with protective devices includes a foundation plate, an annular bearing body, a seismic plate, an impact-resistant module one, an impact-resistant module two, and a concrete square column with a reinforcing cage.

The upper surface of the right-angle flange and the main body of the seismic plate have multiple stiffening ribs arranged laterally. In addition, the seismic plate has pin holes that are equal in number and correspond one-to-one with the number of threaded sleeves. Each pin hole is equipped with a fastening bolt.

[0018] Furthermore, a long strip-shaped mounting plate is fixed to the lower back of the first housing. The mounting plate has slots on the side away from the first housing, which are equal in number and correspond one-to-one with the stiffening ribs.

[0019] The mounting plate is placed above the right-angle flange, and each stiffening rib is located in its corresponding slot. The mounting plate is fixedly connected to the right-angle flange bolt below it.

[0020] Furthermore, the first housing includes a first bottom plate, a front side plate, a rear side plate, a left side plate, a right side plate, and a first top plate. The front side plate and the rear side plate are fixed to the front and rear sides of the first bottom plate, and the left side plate and the right side plate are fixed to the left and right sides above the first bottom plate.

[0021] The first box has two partitions symmetrically arranged on the inner side, and both partitions are arranged vertically, dividing the internal space of the first box into a middle cavity and two side cavities.

[0022] The first top plate is embedded inside the first box. The top plate is bolted to the upper end of the two partitions, and its left and right ends are respectively fixed to the left side plate and the right side plate.

[0023] Furthermore, the first buffer assembly includes a first corrugated plate and two sets of springs. There are multiple first corrugated plates, and each first corrugated plate is arranged in the middle cavity from front to back at intervals. The left and right ends are respectively detachably and fixedly connected to two partitions.

[0024] Two sets of springs are respectively installed inside the two side cavities. Each set of springs includes multiple springs arranged in parallel from top to bottom. The two ends of each spring are detachably and fixedly connected to the front side plate and the rear side plate, respectively, and the spring is kept in a tensioned state.

[0025] The interior of the central cavity and the two side cavities are filled with elastic fillers formed by the solidification of POZD material.

[0026] Furthermore, each of the first corrugated plates has a connecting seat at its left and right ends respectively. The two connecting seats located at the same end of the first corrugated plate are arranged opposite each other and fixed to the two partitions respectively. The left and right ends of the first corrugated plate are respectively bolted to the two connecting seats.

[0027] Each spring is fitted with a bellows, and a flange seat is provided at each of its front and rear ends. Each flange seat has multiple studs integrally formed on the opposite side. The end of each stud protrudes through the front or rear side plate of the first housing and is equipped with a locking nut.

[0028] Furthermore, the second housing includes a second bottom plate, an inner arc plate, an outer arc plate, and a second top plate. The inner arc plate and the outer arc plate are both 1 / 4 arc plates and are coaxially arranged above the second bottom plate. Their lower ends are fixedly connected to the second bottom plate. The corresponding ends of the inner arc plate and the outer arc plate are fixedly connected by an end plate.

[0033] By adopting the above technical solution, the beneficial technical effects of this invention are as follows: The protective part of this invention is constructed using impact-resistant modular assembly. The modular structure facilitates mass manufacturing and assembly. Arc-shaped impact-resistant modules are used at the corners of the square column, resulting in good overall integrity and easy, rapid repair after damage. This invention utilizes a combination of corrugated steel plates and POZD elastic materials to improve the buffering and energy absorption effect, significantly enhancing seismic and impact resistance. The protective device is modularly connected; the overall form of the impact-resistant protective device is a ring surrounding the outside of the reinforced concrete column, connected in box-type modules. The four corners of the column are arc-shaped box-type modules, which can buffer impacts. Individual impact-resistant modules of the impact-resistant protective device are detachable, and the combination of corrugated plates and POZD elastic materials is replaceable, thus increasing the service life and facilitating device inspection and maintenance. The impact-resistant modules are installed through annular bearings pre-embedded in the outer wall of the column. The column is connected to the foundation through the annular bearings, improving the overall seismic and impact resistance. Attached Figure Description

[0044] To make the advantages and technical solutions of the present invention clearer and more explicit, the present invention will be described in detail below with reference to specific embodiments.

[0045] Combination Figures 1 to 9 An impact- and seismic-resistant prefabricated column with protective devices includes a foundation plate 1, an annular bearing body 2, a seismic plate 3, an impact-resistant module one, an impact-resistant module two, and a concrete square column 6 with a reinforcing cage. The foundation plate 1 has a square opening 11. The foundation plate 1 is fitted on the outside of the concrete square column 6 and is fixedly connected to the base 101 below the concrete square column 6. The size of the square opening 11 is slightly larger than the cross-sectional size of the concrete square column 6. Before the concrete square column 6 is poured, the foundation plate 1 is placed on the upper surface of the already formed and cured base 101. The tied reinforcing cage is located inside the square opening 11, and the lower end of the reinforcing cage is fixed inside the base 101.

[0046] The annular bearing 2 is fitted on the outside of the concrete square column 6 and located above the foundation plate 1. The annular bearing 2 is fixedly connected to the four side walls of the concrete square column 6. Before pouring the concrete square column 6, the annular bearing 2 needs to be installed in place and a template needs to be installed on the top of the annular bearing 2.

[0047] The ring-shaped support body 2 includes a pre-embedded plate 21 and a right-angle connecting assembly. The pre-embedded plate 21 is a square steel plate and there are four of them. The four pre-embedded plates 21 are arranged vertically adjacent to each other on the outside of the four side walls of the concrete square column 6. The back of each pre-embedded plate 21 is fixedly connected to the concrete square column 6 through the pre-embedded assembly.

[0048] The embedded component includes four fasteners 22 and multiple threaded sleeves 23. These four fasteners 22 are arranged in a square array. One end of each fastener 22 is fixedly welded to the embedded plate 21, and the end furthest from the embedded plate 21 has a U-shaped groove that mates with the stirrups of the concrete square column 6. The function of the fasteners 22 is to fix the embedded plate 21 to the outside of the reinforcing cage. The U-shaped groove at the end of the fastener 22 engages with the stirrups. After the concrete square column 6 solidifies, all fasteners 22 and all threaded sleeves 23 are fixedly embedded inside the concrete square column 6, and the four embedded plates 21 are firmly fixed to the four side walls of the concrete square column 6.

[0049] All threaded sleeves 23 are distributed in a matrix and arranged perpendicularly to the embedded plate 21. One end of the embedded plate 21 is fixedly welded. The embedded plate 21 has through holes 211 that are equal in number and correspond one-to-one with the threaded sleeves 23. Each through hole 211 communicates with the interior of the corresponding threaded sleeve 23.

[0050] The corresponding sides of any two adjacent embedded plates 21 are fixedly connected by a right-angle connecting assembly. Specifically, the right-angle connecting assembly includes an angle iron 24, a first connecting plate 25, and a second connecting plate 26. The angle iron 24 is vertically arranged and fastened to the right-angled outer wall of the concrete square column 6. Its inner side has multiple clamping plates 27 arranged at intervals along its length. The clamping plates 27 have slots that mate with the longitudinal reinforcement of the concrete square column 6. The function of the right-angle connecting assembly is to achieve a fixed connection between adjacent embedded plates 21, connecting the four vertically arranged embedded plates 21 into a ring structure.

[0051] The first connecting plate 25 and the second connecting plate 26 are arranged on the outer side wall of the angle iron 24 and fixedly welded to it to form an integral structure. The first connecting plate 25 and the second connecting plate 26 are respectively bolted to the corresponding ends of the two adjacent embedded plates 21 of the angle iron 24.

[0052] Each embedded plate 21 is provided with an anti-seismic plate 3 on the side away from the concrete square column 6, and the embedded plate 21 is detachably and fixedly connected to the foundation plate 1 through the corresponding anti-seismic plate 3.

[0053] Specifically, the front sidewall of the embedded plate 21 has a plurality of regularly distributed positioning hooks 212, and the anti-seismic plate 3 has hanging holes 31 that are equal in number and correspond one-to-one with the positioning hooks 212. The anti-seismic plate 3 is arranged adjacent to the front sidewall of the anti-seismic plate 3 through the positioning hooks 212.

[0054] The lower end of the seismic plate 3 is bent outward to form a right-angle flange 32. The upper surface of the right-angle flange 32 and the main body of the seismic plate 3 have multiple stiffening ribs 33 arranged laterally at intervals. In addition, the seismic plate 3 has pin holes 34 that are equal in number and correspond one-to-one with the threaded sleeves 23. Each pin hole 34 is equipped with a fastening bolt.

[0055] After the concrete square column 6 is formed, an anti-seismic plate 3 is hung on the outer wall of each embedded plate 21. The positioning hook 212 can quickly position the anti-seismic plate 3 on the outer wall of the embedded plate 21. Then, the fastening bolts are inserted into the pin hole 34, the through hole 211 and the corresponding threaded sleeve 23 in sequence and tightened. The four anti-seismic plates 3 are fixedly connected to the four embedded plates 21 respectively. Then, an impact-resistant module 1 is fixedly installed on the outside of each anti-seismic plate 3 and connected to form a ring-shaped protective device around the concrete square column 6 through the four impact-resistant modules 2.

[0056] The first impact-resistant module is provided in four parts. The first impact-resistant module includes a first housing 4 and a first buffer component. The first housing 4 is a rectangular shell structure. The first buffer component is located inside the first housing 4. The four first impact-resistant modules are respectively located on the side of the four anti-vibration plates 3 away from the annular bearing 2. Each first impact-resistant module is detachably and fixedly connected to the corresponding anti-vibration plate 3.

[0057] The first housing 4 includes a first bottom plate, a front side plate 41, a rear side plate 42, a left side plate 43, a right side plate 44, and a first top plate 45. The front side plate 41 and the rear side plate 42 are fixed to the front and rear sides of the first bottom plate, and the left side plate 43 and the right side plate 44 are fixed to the left and right sides above the first bottom plate.

[0058] A long strip-shaped mounting plate 46 is fixed to the lower back of the first housing 4. The mounting plate 46 has slots 461 on the side away from the first housing 4, which are equal in number and correspond one-to-one with the stiffening ribs 33. The mounting plate 46 is placed above the right-angle flange 32, and each stiffening rib 33 is located in the corresponding slot 461. The mounting plate 46 is bolted to the right-angle flange 32 below it.

[0059] The inner side of the first housing 4 is symmetrically provided with two partitions 47, both of which are arranged vertically, dividing the internal space of the first housing 4 into a middle cavity and two side cavities. The first top plate 45 is embedded in the inner side of the first housing 4, and is bolted to the upper end of the two partitions 47. Its left and right ends are respectively fixedly connected to the left side plate 43 and the right side plate 44.

[0060] The first buffer assembly includes a first corrugated plate 61 and two sets of springs 62. There are multiple first corrugated plates 61, and each first corrugated plate 61 is arranged in the middle cavity from front to back at intervals. The left and right ends are respectively detachably and fixedly connected to two partitions 47.

[0061] Specifically, each of the first corrugated plates 61 has a connecting seat 63 at its left and right ends. The two connecting seats 63 located at the same end of the first corrugated plate 61 are arranged opposite to each other and fixed on the two partition plates 47 respectively. The left and right ends of the first corrugated plate 61 are bolted to the two connecting seats 63 respectively.

[0062] Two sets of springs 62 are respectively installed inside the two side cavities. Each set of springs 62 includes multiple springs 62 arranged in parallel from top to bottom. The two ends of each spring 62 are detachably and fixedly connected to the front side plate 41 and the rear side plate 42, respectively, and the spring 62 is kept in a tensioned state. Each spring 62 is fitted with a bellows, and a flange seat 64 is provided at each of its front and rear ends. The opposite sides of the two flange seats 64 have multiple studs integrally formed with them. The end of each stud protrudes from the front side plate 41 or the rear side plate 42 of the first housing 4 and is equipped with a locking nut.

[0063] The interior of the intermediate cavity and the two side cavities are filled with elastic fillers 9 formed by solidification of POZD material. After the first corrugated plate 61 and the two sets of springs 62 are installed inside the first housing 4, POZD material is filled into the first housing 4. After solidification, the elastic filler 9 in the intermediate cavity is integrated with all the first corrugated plates 61. Since the springs 62 are covered with corrugated tubes, the elastic filler 9 in the side cavities is integrated with the outer wall of the corrugated tubes, thereby improving the impact and seismic resistance of the first housing 4.

[0064] Any two adjacent shock-resistant modules 1 are detachably and fixedly connected by a shock-resistant module 2. Specifically, the shock-resistant module 2 includes a second housing 5 and a second buffer assembly. The second housing 5 is a 1 / 4 circular shell structure, and the second buffer assembly is located inside the second housing 5.

[0065] The second housing 5 includes a second bottom plate 51, an inner arc plate 52, an outer arc plate 53, and a second top plate 55. The inner arc plate 52 and the outer arc plate 53 are both 1 / 4 arc plates and are coaxially arranged above the second bottom plate 51. Their lower ends are fixedly connected to the second bottom plate 51. The corresponding ends of the inner arc plate 52 and the outer arc plate 53 are fixedly connected by an end plate 54. The second top plate 55 is fixedly embedded in the upper part of the inner side of the second housing 5.

[0066] The upper ends of each left side plate 43 are fixedly connected to the upper ends of the adjacent end plates 54 by means of clips 7 with bolts, and the upper ends of each right side plate 44 are also fixedly connected to the upper ends of the adjacent end plates 54 by means of clips 7 with bolts.

[0067] The second buffer assembly includes at least two second corrugated plates 8, all of which are equally spaced on a circumference centered on the axis of the inner arc plate 52 or the outer arc plate 53. Each second corrugated plate 8 has a connecting seat 81 at both ends. The two connecting seats 81 located at the ends of the same second corrugated plate 8 are fixed to the inner arc plate 52 and the outer arc plate 53 respectively, and are arranged opposite to each other. The second corrugated plate 8 is bolted to the two connecting seats 81.

[0068] The interior of the second housing 5 is filled with an elastic filler 9 formed by solidification of POZD material. It should be emphasized that the elastic filler 9 also fills the space between any two adjacent second corrugated plates 8 and is integrated with each second corrugated plate 8 to improve the impact resistance and seismic resistance of the second housing 5.
