Description

Technical Field

[0001] The utility model relates to the technical field of building structure equipment, in particular to a berth lower crossbeam reinforcement structure. Background Art

[0002] Berth is a special term in navigation, which refers to the location in the port area where ships can dock. The lower beam of the berth is one of the important load-bearing building structures in the berth. After the berth load-bearing columns are completed, the lower beam will be cast. At the same time, the completion of the casting of the lower beam also means that the support structure of the building is completed.

[0003] In the existing technology, when the berth lower beam is actually put into use, it not only meets the load-bearing requirements, but is also severely eroded by sea breeze. If it is put into use directly after pouring, it will suffer from severe erosion, making it difficult to meet the requirements of the specifications and its service life will be difficult to reach the designed life. Therefore, we propose a reinforcement structure for the berth lower beam to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the prior art and to propose a berth lower beam reinforcement structure.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A berth lower beam reinforcement structure includes hanging steel bars, on which a protective structure is provided;

[0007] The protective structure includes a reinforced steel plate, which is coated with steel glue. The reinforced steel plate is also covered with a U-shaped guard plate. A plurality of steel bars are arranged between the U-shaped guard plate and the reinforced steel plate. The U-shaped guard plate is fixedly connected to the hanging steel bars by a basket screw. Sealant is arranged between the edge of the U-shaped guard plate and the reinforced steel plate, and a connecting strip is arranged inside the U-shaped guard plate. A colored reagent is filled between the connecting strip and the sealant.

[0008] Preferably, the U-shaped guard plate includes a main body, a connecting plate is provided at the upper end of the main body, a reinforcing block is provided between the connecting plate and the main body, a traction hook is provided at the upper end of the connecting plate, and the traction hook is rotatably connected to the basket screw.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The present invention, by providing a reinforcing steel plate in combination with a U-shaped guard plate, can not only indicate the supporting strength of the entire lower crossbeam and share the load borne by the concrete portion of the lower crossbeam, but also provide a covering and protection for the reinforcing steel plate and concrete. By providing a reinforcing rod in combination with a sealant, when the reinforcing rod loses its sealing due to damage to the U-shaped guard plate, the reinforcing rod rusts and expands, causing the colored reagent to flow out, thus providing a warning to the management personnel before the reinforcing steel plate and the inner wall concrete are corroded;

[0014] 2. The utility model provides a U-shaped guard plate composed of a main body, a connecting plate and a reinforcement block. On the one hand, the main body is used to cover both sides of the lower cross beam and the reinforcement steel plate to prevent erosion by sea breeze and damage to the strength.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-3 , a berth lower beam reinforcement structure, comprising a hanging steel bar 1, on which a protective structure is provided;

[0021] The construction method of the hanging steel bar 1 is to chisel the concrete on the side wall of the lower crossbeam 10 after the pouring is completed until the internal steel bars of the lower crossbeam 10 are exposed, and the hanging steel bar 1 is fixedly connected to the internal steel bars, and then the area is repaired;

[0022] The protective structure includes a reinforcing steel plate 2, which is coated with steel glue, and the reinforcing steel plate 2 is also covered with a U-shaped guard plate 3, and a plurality of steel bars 5 are arranged between the U-shaped guard plate 3 and the reinforcing steel plate 2, wherein the steel bars 5 are steel bar residues at the construction site, and the steel bars 5 are not treated with anti-corrosion. The steel bars 5 are mainly used for rust expansion of the inner wall of the U-shaped guard plate 3, driving the U-shaped guard plate 3 to expand outward to achieve an indication effect, and the U-shaped guard plate 3 is fixedly connected to the hanging steel bar 1 by a basket screw 4, and a sealant 6 is provided between the edge of the U-shaped guard plate 3 and the reinforcing steel plate 2, and a connecting strip 7 is provided in the U-shaped guard plate 3, and a colored reagent is filled between the connecting strip 7 and the sealant 6;

[0023] In the above design, before the construction of the reinforcement steel plate 2, it is necessary to first grind the bottom of the lower crossbeam 10 and then roughen the bottom to ensure that the steel glue can tightly adhere the reinforcement steel plate 2 to the lower crossbeam 10. After the reinforcement steel plate 2 is fixed with a U-shaped hoop until the steel glue is completely cured, the U-shaped guard plate 3 is constructed and installed. After the installation is completed, the sealant 6 is used to fill the seams. After the sealant 6 is filled, the colored reagent is injected inward from the uppermost end of the cured sealant 6.

[0024] In this design, the reinforcing steel plate 2 is mainly used to improve the supporting strength of the lower cross beam 10, and the external implanted steel bars assist in strengthening the supporting strength of the lower cross beam 10. The U-shaped guard plate 3, on the one hand, covers the side of the lower cross beam 10 to prevent erosion of the lower cross beam 10, and on the other hand, connects the internal steel bars of the lower cross beam 10 with the external reinforcing steel plate 2 to separate the lower cross beam 10 from bearing the load. In addition, by arranging colored reagents and steel bars 5, after the sealing of the U-shaped guard plate 3 is damaged, the steel bars 5 will rust before the U-shaped guard plate 3 and the reinforcing steel plate 2. The rusted and expanded steel bars 5 can drive the sealant 6 to crack, causing the colored reagent to flow out, thereby providing an extremely obvious reminder to the management personnel.

[0025] Furthermore, the U-shaped guard plate 3 includes a main body 31, a connecting plate 32 is provided at the upper end of the main body 31, and a reinforcing block 33 is provided between the connecting plate 32 and the main body 31, and a traction hook 34 is provided at the upper end of the connecting plate 32, and the traction hook 34 is rotatably connected to the basket screw 4;

[0026] In this design, the connecting plate 32 is in contact with the lower cross beam 10 , and the reinforcing block 33 ensures that the pulling force of the connecting plate 32 on the main body 31 is directed upward, thereby stabilizing the direction of the force.

[0027] Furthermore, both ends of the reinforcing steel plate 2 are fixedly connected with vertical plates 8, and fixing holes are set on the vertical plates 8, and the vertical plates 8 are fixedly connected with obliquely arranged support rods 9;

[0028] In this design, the fixing holes are used to fix the vertical plate 8 to the vertical beam, and then the inclined support rods 9 are used to support the middle part of the lower cross beam 10, thereby improving the supporting effect of the vertical beam on the middle part of the lower cross beam 10 and dispersing the load of the lower cross beam 10.

[0029] Furthermore, the main body 31 is coated with a brittle coating. When the steel bar 5 rusts and expands and the main body 31 is damaged by erosion, the brittle coating will show obvious cracking and peeling. This is significantly different from the appearance of the coating itself peeling off due to weathering and other factors. It can make it more convenient for management personnel to inspect the pipelines of the lower beam 10 and the U-shaped guard plate 3.

[0030] Furthermore, the main body 31 is made of Q355B carbon steel plate, and the surface of the main body 31 is hot-dip galvanized;

[0031] Among them, Q355B steel plate is a low-alloy high-strength structural steel plate, whose chemical composition contains a certain proportion of carbon, silicon, manganese, sulfur, phosphorus and other elements. It is produced by controlled rolling and controlled cooling process. After heat treatment, it has good toughness and strength, and meets the same construction standards as the building materials of the lower crossbeam 10 main body 31. At the same time, as external steel, hot-dip galvanizing treatment can further enhance the anti-corrosion ability of the main body 31.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
