Description

Technical Field

[0001] This utility model relates to the technical field of port terminal accessories, specifically to a prefabricated berthing component for a terminal. Background Technology

[0002] Precast berthing components are an important part of wharf construction, ensuring normal berthing of ships and the structural safety of the wharf during low water levels. At the same time, the installation of these precast berthing components is a critical stage in wharf construction, directly impacting the construction progress and quality.

[0003] The existing prefabricated berthing components at wharves generally adopt vertical cantilever beam prefabricated reinforced concrete structures. Typically, the installation and joint pouring are completed on the water. During the installation process, the cantilever beam needs to be hoisted to the corresponding installation position and installed. Because the prefabricated cantilever beam is large in size and heavy in weight, hoisting is difficult, construction is challenging, and installation accuracy is not high.

[0004] In summary, there is an urgent need for a prefabricated berthing component for wharves to solve or at least partially solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated berthing component, which aims to solve the problems of heavy weight, difficult installation, and high construction difficulty of existing berthing components. The specific technical solution is as follows:

[0006] A prefabricated berthing component for a wharf includes a hollow beam and a connector. The hollow beam is a prefabricated component and is arranged in a hollow manner. The connector is arranged on the top of the hollow beam and is used to connect the hollow beam to the lower part of the protruding end of a pre-embedded part in the wharf.

[0007] Furthermore, the hollow beam includes a base, a lifting ring, and a post-cast cover. A weight-reducing groove is provided on the base, facing upwards, and the upper end of the weight-reducing groove is open. The post-cast cover is arranged on the upper part of the base and closes the opening of the weight-reducing groove. The lower end of the connector passes through the post-cast cover and is embedded in the base, while the upper end of the connector extends out of the post-cast cover. The first end of the lifting ring passes through the post-cast cover and is embedded in the base, while the second end of the lifting ring extends out of the post-cast cover.

[0008] Furthermore, the hollow beam also includes a precast cover, with a cover plate groove arranged on the base. The cover plate groove is located at the opening of the weight reduction groove, and the precast cover is closed in the cover plate groove. The post-cast sealing cover is arranged on the top of the precast cover.

[0009] Preferably, the hollow beam includes a base and a lifting ring. The base has a weight-reducing groove with an open upper end. The lifting ring is arranged at the upper end of the base and is embedded in the base. The lower end of the connector is embedded in the base.

[0010] Furthermore, the lifting ring is an inverted U-shaped lifting ring, with its two free ends embedded in the base, and its bent end extending out of the base to form a closed annular lifting ring with the base.

[0011] Furthermore, the substrate is arranged with a larger top and a smaller bottom.

[0012] Furthermore, the connector includes a first screw, a second screw, two first nuts, two second nuts, a lower pressure plate, and an upper pressure plate. The first and second screws are arranged vertically side by side, with their lower ends embedded in the hollow beam and their upper ends extending out of the hollow beam. The lower and upper pressure plates are both threaded onto the extended ends of the first and second screws, with the upper pressure plate positioned above the lower pressure plate. The two first nuts are threaded onto the extended ends of the first and second screws, respectively, and are positioned below the lower pressure plate. The two second nuts are threaded onto the first and second screws, respectively, and are positioned above the upper pressure plate. The hollow beam is clamped to the extended ends of the embedded parts in the dock by the upper and lower pressure plates on the connector.

[0013] Furthermore, the connector also includes two limiting blocks, which are fixedly connected to the lower ends of the first screw and the second screw, respectively.

[0014] Furthermore, four sets of connectors are arranged, with each set positioned at one of the four corners of the hollow beam. These four sets of connectors connect the hollow beam to the embedded parts of the wharf.

[0015] The application of the technical solution of this utility model has the following beneficial effects:

[0016] When installing hollow beams, because they are hollow and lightweight, smaller hoisting equipment can be used, making hoisting easier. In addition, because of their light weight and relatively small inertia, less force is needed for manual assistance during the positioning process, making installation easier. This design reduces the difficulty of construction and improves installation accuracy and efficiency.

[0029] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] Example 1:

[0032] See Figures 1-7 The existing wharf includes pile foundation 1, pile cap 2 and precast berthing components 3. Pile cap 2 is arranged on pile foundation 1. Pile cap 2 includes a pre-cast part 21, embedded part 22 and a post-cast part 23. The pre-cast part 21 is arranged on pile foundation 1. The embedded part 22 is embedded at one end of the pre-cast part 21 and partially extends out of the end of the pre-cast part 21. The post-cast part 23 is cast above the hollow beam 31 and wraps the embedded part 22 and the connector 32. Specifically, the pile foundation 1 includes two piles. The first-cast portion 21 is arranged on the two piles through a casting construction method. Before casting the first-cast portion 21, the embedded part 22 is pre-embedded in the first-cast portion 21 and partially protrudes from one end of the first-cast portion 21. After the first-cast portion 21 is completely solidified, the hollow beam 31 is hoisted to the protruding end of the embedded part 22 in the first-cast portion 21 and installed with the embedded part 22 through the connector 32. Columns, a wharf platform, and corresponding crane rails are erected on the pile cap 2.

[0033] See Figures 1-7 This embodiment provides a prefabricated berthing component 3 for a wharf. The prefabricated berthing component 3 is applied in the aforementioned wharf. The prefabricated berthing component 3 includes a hollow beam 31 and a connector 32. The hollow beam 31 is a prefabricated component and is arranged in a hollow manner. The connector 32 is arranged on the top of the hollow beam 31. The connector 32 is used to connect the hollow beam 31 to the lower part of the protruding end of the embedded part 22 in the wharf, so as to cantilever downward to ensure the normal berthing of ships and the safety of the wharf structure when the water level is low.

[0034] It is known that during the installation of the hollow beam 31, because of its hollow structure and light weight, smaller hoisting equipment can be used, facilitating hoisting. Furthermore, its light weight and relatively low inertia reduce the force required for manual assistance during positioning during hoisting, making construction easier. This design reduces construction difficulty and improves installation accuracy and efficiency. While ensuring design strength, measurements from the existing construction site show that the hollow beam 31 reduces the total weight of the original cantilever beam by approximately 3.5 tons, about 35% of its own weight, significantly reducing the requirements for hoisting equipment.

[0035] Furthermore, the hollow beam 31 includes a base 311, a lifting ring 312, and a post-cast cover. The base 311 is provided with a weight-reducing groove 3111, which is arranged facing upwards and has an open upper end. The post-cast cover 313 is arranged on the upper part of the base 311 and closes the opening of the weight-reducing groove 3111. The lower end of the connector 32 passes through the post-cast cover 313 and is embedded in the base 311, while the upper end of the connector 32 extends out of the post-cast cover 313. The first end of the lifting ring 312 passes through the post-cast cover 313 and is embedded in the base 311, while the second end of the lifting ring 312 extends out of the post-cast cover.

[0036] It is understood that during construction, the lower ends of the lifting ring 312 and the connector 32 are first pre-embedded in the casting mold of the base 311. The base 311 is then poured. After the base 311 has cured, it is flipped so that the groove of the weight-reducing groove 3111 faces downward. The casting mold is then used to support the base 311 to the height of the post-cast cover 313. The post-cast cover 313 is then poured from below. After the post-cast cover 313 has completely cured, a hollow beam 31 is formed. At this point, the hollow beam 31 is flipped again for hoisting. Through this arrangement and construction method, the hollow beam has a hollow internal structure.

[0037] Furthermore, the lifting ring 312 is an inverted U-shaped lifting ring. The two free ends of the inverted U-shaped lifting ring are embedded in the base 311, and the bent end of the inverted U-shaped lifting ring extends out of the base 311, forming a closed annular lifting ring with the base 311. It can be seen that the closed lifting ring facilitates the lifting of the hollow beam 31. The inverted U-shaped lifting ring can be made of bent steel bars, the length of the lifting ring 312 is easily adjustable, and the cost is low, which helps to reduce costs.

[0038] Furthermore, the hollow beam body 31 also includes a precast cover 314, a cover plate groove 3112 is arranged on the base body 311, the cover plate groove 3112 is arranged at the opening of the weight reduction groove 3111, the precast cover 314 is closed in the cover plate groove 3112, and the post-cast sealing cover 313 is arranged on the upper part of the precast cover 314.

[0039] It should be noted that the hollow beam 31 is constructed on the ground and then hoisted to the site for installation. When constructing the hollow beam 31, if the base 311 is arranged facing upwards, the weight-reducing groove 3111 will also face upwards. If concrete is poured directly onto the base 311, the concrete will directly enter the weight-reducing groove 3111, filling it completely and failing to achieve the weight-reducing effect. If the base 311 is inverted, with the weight-reducing groove 3111 facing downwards, the base 3111 needs to be supported before pouring concrete, and the base 3111 needs to be turned over multiple times, making construction inconvenient. With the installation of the cover plate groove 3112 and the precast cover 314, when pouring the post-pouring sealing cover 313, the precast cover 314 is first placed inside the cover plate groove 3112 to seal the opening of the weight reduction groove 3111, and then the post-pouring sealing cover 313 is poured. The entire construction process does not require the base 311 to be turned over, which facilitates construction.

[0040] Furthermore, the base 311 is arranged with a larger upper section and a smaller lower section. It can be seen that when the ship docks, the upper part of the base 311 bears a larger torque, and the lower part bears a smaller torque. By arranging the base with a larger upper section and a smaller lower section, materials are saved while meeting the strength requirements.

[0041] Furthermore, the embedded part 22 includes two horizontally arranged connecting rods, which are arranged side by side and along the length of the first-cast portion 21, to facilitate the installation of the hollow beam 31. In this embodiment, the connecting rod is an I-beam. In some other embodiments of this application, the connecting rod can also be a channel steel, square steel, rail steel, or other rod-type steel.

[0042] Furthermore, the connector 32 includes a first screw 321, a second screw 322, two first nuts 323, two second nuts 324, a lower pressure plate 325, and an upper pressure plate 326. The first screw 321 and the second screw 322 are arranged vertically side by side, and the lower ends of the first screw 321 and the second screw 322 are both embedded in the hollow beam 31, while the upper ends extend out of the hollow beam 31. The lower pressure plate 325 and the upper pressure plate 326 are both inserted through the extended ends of the first screw 321 and the second screw 322, with the upper pressure plate 326 arranged in a specific manner. On the upper part of the lower pressure plate 325, two first nuts 323 are threadedly connected to the protruding ends of the first screw 321 and the second screw 322, respectively, and both first nuts 323 are arranged below the lower pressure plate 325; two second nuts 324 are threadedly connected to the first screw 321 and the second screw 322, respectively, and both second nuts 324 are arranged above the upper pressure plate 326; the hollow beam 31 is clamped on the protruding end of the embedded part 22 in the dock by the upper pressure plate 326 and the lower pressure plate 325 on the connecting member 32. Specifically, the connecting rod is embedded between the first screw 321 and the second screw 322, and the connecting rod is clamped between the upper pressure plate 326 and the lower pressure plate 325.

[0043] It is known that the lower ends of the first screw 321 and the second screw 322 are pre-embedded and fixed in the base 311. During the subsequent installation, the rod is clamped between the upper pressure plate 326 and the lower pressure plate 325 to fix the base 311 to the connecting rod. By adjusting the relative positions of the first nut 323 and the second nut 324 with respect to the first screw 321 and the second screw 322, the height of the base 311 relative to the connecting rod can be adjusted, thereby facilitating the adjustment of the relative position of the hollow beam 31, including leveling the hollow beam 31.

[0044] Furthermore, the connector 32 also includes two limiting blocks 327, which are respectively fixedly connected to the lower ends of the first screw 321 and the second screw 322. Specifically, the two limiting blocks 327 are fixedly connected to the lower ends of the first screw 321 and the second screw 322 by welding, riveting, or threaded connection.

[0045] It is understood that by setting the limiting block 327, the connection stability of the first screw 321 and the second screw 322 embedded in the hollow beam 31 is improved, and the first screw 321 and the second screw 322 are prevented from being pulled out when subjected to force.

[0046] Furthermore, four sets of connectors 32 are arranged, with each set positioned at one of the four corners of the hollow beam 31. The hollow beam 31 is then connected to the embedded parts 22 of the wharf via these four sets of connectors 32. Specifically, two of the four sets of connectors 32 are fixedly connected to one of the connecting rods, while the other two are fixedly connected to the other connecting rod.

[0047] The hollow beam 31 is securely connected to the connecting rod by means of the connector 32. In this embodiment, there are four connectors 32. In some other embodiments of this application, there may be two, three, or more than four connectors 32.

[0048] The construction process and basic working principle of this utility model are as follows:

[0049] During the construction of the wharf, the pile foundation 1 is constructed first, followed by the pre-cast portion 21 on the pile foundation 1. When constructing the pre-cast portion 21, the embedded parts 22 are placed in the casting mold of the pre-cast portion 21 beforehand. While constructing the pile foundation 1 and the pre-cast portion 21, the hollow beam 31 can be constructed simultaneously on the ground. During the construction of the hollow beam 31, the base 311 with a weight-reducing groove 3111 and a cover plate groove 3112 is cast first. When casting the base 311, the connecting... The connector 32 and the lifting ring 312 are embedded in the base 311. Then, the precast cover 314 is placed in the cover plate groove 3112, and the post-cast cover 313 is poured. After the post-cast cover 313 is completely solidified, a hollow beam 31 is formed. The hollow beam 31 is lifted to the embedded part 22 by lifting equipment through the lifting ring 312 for installation. Finally, the post-cast part 23 is constructed. The post-cast part 23 completely covers the connector 32 and the protruding embedded part 22, thus completing the construction.

[0050] Example 2:

[0051] Reference Figure 8 and Figure 9 The difference between this embodiment and embodiment 1 is that, in this embodiment, the hollow beam 31 includes a base 311 and a lifting ring 312. A weight-reducing groove 3111 is arranged on the base 311, and the upper end of the weight-reducing groove 3111 is open. The lifting ring 312 is arranged at the upper end of the base 311 and is embedded in the base 311. The lower end of the connector 32 is embedded in the base 311.

[0052] It is known that for some wharves with higher strength requirements, or when the size of the hollow beam 31 is too small to meet the strength requirements, this setting method is used to lift the base 311 to the installation position using the lifting ring 312, and then install the base 311 onto the embedded part 22 using the connector 32. At this time, the opening of the weight reduction groove 3111 on the base 311 faces upward. When the post-cast part 23 is poured, the weight reduction groove 3111 is filled at the same time, thereby transforming the hollow beam 31 into a solid beam, thus reducing the construction difficulty while fully ensuring the strength of the entire structure.

[0053] The remaining aspects are basically the same as in Example 1, and will not be repeated here.

[0054] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
