Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a steel structure beam for building construction. Background Art

[0002] Steel structural beams for construction refer to steel structural members used for support and load-bearing in construction, and are usually used in large-span buildings or construction projects that need to bear large loads. Steel structural beams are usually composed of main beams (cross beams) and secondary beams (longitudinal beams): the main beam is located in the horizontal direction, bears the main horizontal load and self-weight load, and is usually a steel structural member with a larger span in the building; the secondary beam is located in the longitudinal direction, supports the main beam, and bears part of the horizontal load and self-weight load. The secondary beam usually intersects with the main beam vertically to form the overall structural frame.

[0003] The main beam and the secondary beam are usually connected by welding and bolting. That is, the side wall edges of the secondary beam corresponding to the two main beams are provided with multiple mounting holes. When installing, firstly, the connecting plate with multiple mounting holes is welded to the corresponding end of the two main beams, and then the secondary beam is placed between the two main beams with the help of lifting equipment, and then the secondary beam is connected to the connecting plates on the two main beams by bolts and mounting plates, and the fasteners are used to ensure the firmness of the connection to form a solid connection.

[0004] However, during the connection and fixing operation, since the secondary beam is in a suspended state, it is easy to move, which not only brings potential operation risks to the workers, but also brings inconvenience to the connection and fixing operations of the workers, and often requires the cooperation of multiple people to ensure that the secondary beam remains fixed, which affects the installation progress and has low installation efficiency. To this end, we propose a steel structure beam for construction. Utility Model Content

[0023] See also Figure 3-Figure 5In the figure, the adjustment mechanism includes a square plate 9 and a plurality of sockets 12. The square plate 9 is fixedly connected to the upper edge of the concave plate 6 away from the main beam 1, and the lower end of the square plate 9 is fixedly connected to a cylindrical tube 10.

One of the sockets 12 is slidably matched with the plug column 13. An elastic member and a pulling member are respectively provided between the plug column 13 and the cylindrical tube 10.

[0024] See also Figure 4 In the figure, the elastic member includes an annular plate 14, which is fixedly mounted on the outer wall of the plug column 13, and the upper end of the annular plate 14 is in contact with the inner upper end of the cylindrical tube 10, and a spring 15 is fixedly connected between the lower end of the annular plate 14 and the inner lower end of the cylindrical tube 10, and the spring 15 is slidably mounted on the outer wall of the plug column 13.

[0026] Working principle: When installing the secondary beam 2 between the two main beams 1, firstly suspend the secondary beam 2 between the two main beams 1 with the help of lifting equipment, and adjust the position relationship between the secondary beam 2 and the two main beams 1 so that the two concave plates 6 on the secondary beam 2 correspond to the positions of the connecting plates 3 on the two main beams 1 respectively, and then pull one of the pulling blocks 11 downward, the pulling block 11 will drive the plug column 13 to slide downward in the inner walls of the square plate 9 and the cylindrical tube 10, and the plug column 13 will drive the annular plate 14 to slide downward in the cylindrical tube 10 (in this process, the spring 15 between the cylindrical tube 10 and the annular plate 14 will slide downward on the outer wall of the plug column 13), and the plug column 13 will also slide downward in a corresponding socket 12 on the secondary beam 2 and completely slide out of the socket 12.

[0027] Then, while pulling the pull block 11 downwards without releasing it, the concave plate 6 is moved toward the main beam 1, and the concave plate 6 will slide on the secondary beam 2 toward the main beam 1 (during this process, the two T-shaped plates 7 on the concave plate 6 will slide in the T-shaped grooves 8 on the corresponding secondary beams 2 toward the main beam 1), and the concave plate 6 will slide on the outer wall of the corresponding connecting plate 3, and the lower end of the concave plate 6 is located directly above the inner bottom end of the main beam 1. Then, the pull block 11 is released, and under the action of the spring 15, the plug 13 is inserted into another plug hole 12 on the corresponding secondary beam 2, and the concave plate 6 and the secondary beam 2 can be fixed again. Similarly, according to the same operation, the lower end of another concave plate 6 can be located directly above the inner bottom end of another main beam 1. Then, the secondary beam 2 is moved downward with the help of lifting equipment until the two concave plates 6 on the secondary beam 2 are in contact with the inner bottom ends of the corresponding main beams 1. At this time, the secondary beam 2 can maintain a preliminary fixed state with the two main beams 1. Figure 1 Finally, the subsequent installation work can be carried out.

[0028] It should be noted that when installing the steel structure beam, the secondary beam 2 can be initially fixed between the two main beams 1, which avoids the possibility of displacement compared to the existing suspended secondary beam 2, not only reduces the operating risks of the staff, but also brings convenience to the staff's connection and fixing operations, which is conducive to improving the installation progress and efficiency.
