They are a new type of sustainable development construction production method that can achieve energy conservation, environmental protection and maximization of the value of building materials throughout their life cycle.

[0003] In order to ensure the overall firmness of the building, a steel structure is required for assembly. For example, Chinese patent CN219690882U discloses an assembled steel structure beam, which specifically relates to the field of beam technology, including a beam body, grooves are provided at both ends of the beam body, a clamping block is provided inside the groove, a mounting plate is provided on one side of the clamping block, a mounting groove is provided on a side of the mounting plate contacting the beam body, a vertical beam is provided on one side of the mounting plate, a plurality of first bolts are evenly provided on the outside of the mounting plate, one end of each of the plurality of first bolts passes through the mounting plate and the beam body in sequence and extends into the beam body, and a mounting mechanism is provided on the top of the mounting plate.

This installation method facilitates the installation of the beam body.

[0004] However, there are still problems. When the steel structure is installed, it is only assembled and fixed by multiple bolts, and it is impossible to install the beams and columns more stably. It is not only time-consuming and labor-intensive, but also has poor supporting stability. Therefore, an assembled building steel structure is proposed to solve the above problems.

[0019] Furthermore, a connecting plate is fixed on the front sides of the two cross beams.

[0020] By adopting this technical solution, the connecting plate can connect and fix the two beams, so that the beams will not loosen after being connected to the columns, and the stability is higher.

[0021] Furthermore, the front surface of the connecting plate is threadedly connected with four screws that penetrate into the inner cavity of the beam, and the connecting plate is fixed to the two beams by the screws.

A connecting plate 6 is fixed on the front of the two beams 2. The connecting plate 6 can connect and fix the two beams 2 so that the beams 2 will not loosen after being connected to the column 1, and the stability is higher. The front of the connecting plate 6 is threaded with four screws that penetrate into the inner cavity of the beam 2. The connecting plate 6 is fixed to the two beams 2 by screws. The tops of the two beams 2 are fixed with fixing components 3 that penetrate into the inner cavity of the column 1 and are used to connect and fix the beams 2 to the column 1. The bottom of the beam 2 is fixed with a screw that penetrates into the column 1. The inner cavity connection component 5 consists of a mounting plate and four No. 2 bolts. The mounting plate is located between the crossbeam 2 and the column 1. The mounting plate is L-shaped. Setting the mounting plate into an L-shape can maximize the use of the installation space, reduce unnecessary space waste, and make the connection between the column 1 and the crossbeam 2 tighter. The four No. 2 bolts are all threadedly connected to the outer surface of the mounting plate and penetrate into the inner cavity of the crossbeam 2. The bottom of the crossbeam 2 is provided with a threaded hole compatible with the No. 2 bolts. The connection component 5 can further enhance the stability between the crossbeam 2 and the column 1. The top of the column 1 is plugged with a limit block 4 for limiting the fixing component 3.

[0032] In this embodiment, after the column 1 and the beam 2 are connected and fixed by the fixing assembly 3, the connecting assembly 5 and the connecting plate 6 are used for auxiliary fixing, and finally the steel structure is assembled as a whole, thereby achieving the purpose of good connection stability.

[0033] See also Figure 3-4In order to achieve good connection stability, the fixing assembly 3 in this embodiment includes a fixing block 301, a connecting rod 302, a worm 303, a driving rod 304, two limiting parts 305 and two worm wheels 306. The fixing block 301 is fixed to the top of the beam 2, the connecting rod 302 is fixed to the top of the fixing block 301, the worm 303 is rotatably connected to the left side wall of the inner cavity of the connecting rod 302, the worm 303 is rotatably connected to the ball inner cavity of the connecting rod 302 through a bearing, and the driving rod 304 Fixed on the right side of the worm 303 and extending to the outside of the connecting rod 302, the two limiting parts 305 are rotatably connected between the front side wall and the rear side wall of the inner cavity of the connecting rod 302, and the top and bottom of the connecting rod 302 are provided with movable holes for the limiting parts 305 to move as a whole.
