Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a reinforced steel structure at a joint of steel structures. Background Art

[0002] In the construction industry, it is very common to use steel structures to build buildings. During construction, multiple steel structures are spliced ​​together, and then assembled together to form a main frame before construction continues. To ensure that the spliced ​​steel structures can be used stably, auxiliary connecting structures will be installed at the joints so that the two steel structures can be stably connected together for use.

[0003] At present, most of the ways to connect the joints of steel structures are to use connectors to connect the ends of two steel structures together through connectors to form a whole for use, or to directly weld the joints of two steel structures to form a whole for use.

[0004] Although the above two methods can connect two steel structures together for stable use, the ends of the two steel structures are installed inside the connecting parts when the connecting parts are used. In actual use, for vertically connected steel structures, when one of the steel structures is subjected to external force, one end of the steel structure tends to rotate easily. If this continues for a long time, it is easy to cause the steel structure to move slightly and damage the connecting parts, thereby affecting the connection stability of the two steel structures. For the welding method, the steel structure is used outdoors for a long time, and external environmental factors will cause cracks in the welding position, which makes the two steel structures unable to be stably connected and used. Therefore, a reinforced steel structure at the joint of the steel structure is proposed to solve the above problem. Utility Model Content

[0029] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 4 The utility model provides a technical solution: a reinforced steel structure at the joint of a steel structure, comprising a first steel column 1 and a second steel column 2, a connecting mechanism 4, and mounting holes 3 are opened on the outer surfaces of the first steel column 1 and the second steel column 2, the connecting mechanism 4 comprises a mounting bin 41, the mounting bin 41 is clamped at the connection between the first steel column 1 and the second steel column 2, one end of a limiting plate 42 is rotatably installed inside the mounting bin 41, a positioning hole 421 is opened on the outer surface of the limiting plate 42, a connecting block 43 is fixedly installed at one end of the limiting plate 42, and a connecting plate 44 is rotatably installed on the outer side surface of the limiting plate 42.

[0031] In a preferred embodiment, the mounting bin 41 and the connecting block 43 are respectively connected to the first steel column 1 and the second steel column 2 at their corresponding positions by bolts 5. One side of the mounting bin 41 is set as an opening. To ensure that the mounting bin 41 can be stably installed on the first steel column 1 and the second steel column 2, the mounting bin 41 is fixedly installed on the first steel column 1 and the second steel column 2 by bolts 5 to meet actual use.

[0032] In a preferred embodiment, a through hole 6 is opened on one side of the connecting plate 44, and the bolt 5 on the mounting bin 41 passes through the interior of the through hole 6. Two connecting plates 44 are provided, and are respectively located on both sides of the limiting plate 42. In actual use, when one end of the second steel column 2 moves upward, it is easy to support the mounting bin 41, which is easy to lift up the mounting bin 41 for a long time. Therefore, in order to ensure that the mounting bin 41 can be stably installed on the first steel column 1 and the second steel column 2, a connecting plate 44 is installed between the mounting bin 41 and the limiting plate 42. The pulling of the connecting plate 44 can prevent the mounting bin 41 from being lifted up.

[0033] In a preferred embodiment, the inside of the installation bin 41 is fixedly connected to the round rod 7, and the outside of the round rod 7 is rotatably connected to the limit plate 42. The device is provided with a rotatable limit plate 42 on one side of the installation bin 41, and a triangle is formed with the limit plate 42, the first steel column 1 and the second steel column 2. The triangle is stable and can improve the connection stability of the first steel column 1 and the second steel column 2.

[0034] This device installs the connecting block 43 on the first steel column 1 to realize the positioning of the limit plate 42. In order to improve the stable installation effect of the limit plate 42, a reinforcing mechanism 8 is installed on the outside of the limit plate 42. The reinforcing mechanism 8 includes a U-shaped rod 81, a nut 82 and a fixing plate 83. The outer side surface of the limit plate 42 is fixedly connected to the fixing plate 83. A threaded column 9 is arranged inside the fixing plate 83. The threaded column 9 is fixedly connected to the U-shaped rod 81. The threaded column 9 passes through the inside of the fixing plate 83. The threaded column 9 is threadedly connected to the nut 82. The outer side surface of the limit plate 42 is fixedly connected to the rectangular plate 11. A plug hole 10 is opened on one side of the rectangular plate 11.

[0035] In actual use, after positioning the limit plate 42, the threaded column 9 on the U-shaped rod 81 is passed through the interior of the fixed plate 83, and then the nut 82 is screwed onto the outer end of the threaded column 9. The connecting block 43 is positioned through the U-shaped rod 81. The connecting block 43 and the limit plate 42 are integrated, so the limit plate 42 can be positioned, thereby improving the installation stability of the limit plate 42, thereby indirectly improving the connection stability of the first steel column 1 and the second steel column 2.

[0036] Specifically, the working process or working principle of a reinforced steel structure at a steel structure joint is: currently, the connection method of the steel structure joint is mostly to use a connector, connect the ends of the two steel structures together through the connector to form a whole, or directly weld the connection of the two steel structures to form a whole.

[0037] Although the above two methods can connect two steel structures together for stable use, the ends of the two steel structures are installed inside the connecting parts when the connecting parts are used. In actual use, for vertically connected steel structures, when one of the steel structures is subjected to external force, one end of the steel structure tends to rotate easily. If this continues for a long time, it is easy to cause the steel structure to move slightly and damage the connecting parts, thereby affecting the connection stability of the two steel structures. For the welding method, the steel structure is used outdoors for a long time, and external environmental factors will cause cracks to appear at the welding point, which makes the two steel structures unable to be stably connected and used. Therefore, this device is designed to solve this problem.

[0038] Reference Figure 1-Figure 3 , the device can stably connect the first steel column 1 and the second steel column 2 for stable use. The specific operation is to vertically connect the first steel column 1 and the second steel column 2, and the outer side surface of the second steel column 2 is flush with the end surface of the first steel column 1. After maintaining this shape, the installation bin 41 is clamped at the connection between the first steel column 1 and the second steel column 2, and the installation bin 41 is fixedly installed on the first steel column 1 and the second steel column 2 by bolts 5, so that the first steel column 1 and the second steel column 2 are stably connected together, and then the limiting plate 42 is rotated so that the connecting block 43 on the end of the limiting plate 42 can be attached to the outer surface of the first steel column 1 and is also fixedly connected to the first steel column 1 by bolts 5, and a triangle is formed with the limiting plate 42, the first steel column 1 and the second steel column 2. The triangle has stability and can improve the connection stability of the first steel column 1 and the second steel column 2.

[0039] After positioning the limit plate 42, rotate one end of the connecting plate 44 on the limit plate 42 to a position outside the mounting bin 41, and use the bolt 5 to position the connecting plate 44 outside the mounting bin 41. Limiting the mounting bin 41 by the connecting plate 44 can increase the installation stability of the mounting bin 41, and effectively prevent the upward movement of one end of the second steel column 2 from causing damage to the mounting bin 41.

[0040] In order to improve the installation stability of the limit plate 42, after positioning the limit plate 42, the threaded column 9 on the U-shaped rod 81 is passed through the interior of the fixed plate 83, and then the nut 82 is screwed on the outer end of the threaded column 9. The connecting block 43 is positioned by the U-shaped rod 81. The connecting block 43 and the limit plate 42 are integrated, so the limit plate 42 can be positioned, and the installation stability of the limit plate 42 is improved, thereby indirectly improving the connection stability of the first steel column 1 and the second steel column 2.

[0041] Reference Figure 4 When the first steel column 1 and the second steel column 2 are vertically connected, the device can be sleeved on the outside of the second steel column 2 and slid down to the connection position of the first steel column 1 and the second steel column 2. In this state, the limit plate 42 rotates to a vertical state and fits the side of the installation bin 41, and then the bolts 5 are used to fix the installation bin 41 and the limit plate 42 on the first steel column 1 and the second steel column 2, so that the first steel column 1 and the second steel column 2 are stably connected together, and then the U-shaped rod 81 is sleeved on the outside of the installation bin 41. The U-shaped rod 81 is selected to be of an appropriate size and can be sleeved on the outside of the installation bin 41. The U-shaped rod 81 is connected to the rectangular plate 11 by a nut 82, so that the installation bin 41 and the limit plate 42 can be limited, thereby improving the connection stability of the first steel column 1 and the second steel column 2.
