Summary of the invention The purpose of the present invention is to solve the shortcomings of the prior art and to propose a new modular assembled earthquake-resistant steel structure.

[0003] To achieve the above objectives, the present invention provides a modular assembled new earthquake-resistant steel structure, comprising a first connecting frame and a second connecting frame, one end of the second connecting frame is fixedly connected to a connecting plate, the surfaces of the connecting plate and the first connecting frame are both provided with connecting holes, the surface of the connecting plate is provided with a connecting mechanism for connecting with the first connecting frame, and a reinforcing plate is fixedly connected at an angle between the surface of the connecting plate and the second connecting frame; The connection mechanism comprises an anti-loosening component and a reinforcing component arranged on the surface of the connection plate; Among them, the reinforcement component includes a mounting column fixedly connected to the surface of the connecting plate, a mounting cavity is opened inside the mounting column, a docking hole connected to the mounting cavity is opened on one side of the connecting plate close to the first connecting frame, and a connecting cavity is opened on the inner wall of the mounting cavity.

[0004] In the above technical solution, further, the reinforcement assembly also includes a connecting rod fixedly connected to the surface of the first connecting frame, and the other end of the connecting rod passes through the docking hole and extends to the interior of the installation cavity.

[0005] In the above technical solution, further, the inner wall of the connecting rod is rotatably connected to a rotating shaft, and a locking block is fixedly connected to the middle of the surface of the rotating shaft. The cross-sectional shape of the locking block is drop-shaped, and one end of the locking block passes through the connecting rod and extends to the inside of the connecting cavity.

[0006] In the above technical solution, further, two symmetrically distributed mainsprings are fixedly connected to the surface of the rotating shaft, and the other ends of the mainsprings are fixedly connected to the inner wall of the connecting rod.

[0007] In the above technical solution, further, the anti-loosening component includes a bolt arranged on the inner side of the first connecting frame, one end of the bolt passes through two interconnected connecting holes in sequence and a nut is threadedly connected to the surface, and one end of the bolt away from the nut is fixedly connected to a connecting block.

[0008] In the above technical solution, further, a groove coaxially arranged with the connecting hole is provided on the surface of the connecting plate, and a resistance-increasing pattern is provided on the inner wall of the groove. The nut covers the groove, and a resistance-increasing block is slidably connected to the inner wall of the nut.

DETAILED DESCRIPTION

[0015] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1-Figure 6 A modular assembled new earthquake-resistant steel structure is shown, comprising a first connecting frame 1 and a second connecting frame 101, one end of the second connecting frame 101 is fixedly connected to a connecting plate 2, the surfaces of the connecting plate 2 and the first connecting frame 1 are both provided with connecting holes 102, the surface of the connecting plate 2 is provided with a connecting mechanism for connecting with the first connecting frame 1, and a reinforcing plate 201 is fixedly connected at an angle between the surface of the connecting plate 2 and the second connecting frame 101; The connection mechanism includes an anti-loosening component 4 and a reinforcement component 3 arranged on the surface of the connection plate 2; Among them, the reinforcement component 3 includes an installation column 301 fixedly connected to the surface of the connecting plate 2, and an installation cavity is opened inside the installation column 301. A docking hole connected to the installation cavity is opened on the side of the connecting plate 2 close to the first connecting frame 1, and a connecting cavity 303 is opened on the inner wall of the installation cavity.

[0017] like Figure 1-Figure 6 As shown, the reinforcement assembly 3 further includes a connecting rod 302 fixedly connected to the surface of the first connecting frame 1, and the other end of the connecting rod 302 passes through the docking hole and extends to the interior of the installation cavity.

[0018] The inner wall of the connecting rod 302 is rotatably connected to a rotating shaft 306 , and a locking block 304 is fixedly connected to the middle of the surface of the rotating shaft 306 . The cross-sectional shape of the locking block 304 is teardrop-shaped, and one end of the locking block 304 passes through the connecting rod 302 and extends to the inside of the connecting cavity 303 .

[0019] Two symmetrically distributed mainsprings 305 are fixedly connected to the surface of the rotating shaft 306 , and the other ends of the mainsprings 305 are fixedly connected to the inner wall of the connecting rod 302 .

[0020] When the second connecting frame 101 is installed on the first connecting frame 1, first press the locking block 304 to make it shrink into the inside of the connecting rod 302, and then align the connecting rod 302 with the docking hole on the connecting plate 2 and insert it. During this process, the inner wall of the docking hole can squeeze the locking block 304 to keep it shrinking into the inside of the connecting rod 302 until it is installed in place. At this time, the locking block 304 can be located in the connecting cavity 303, and under the resetting action of the spring 305, the rotating shaft 306 drives the locking block 304 to flip and insert into the inside of the connecting cavity 303. At this time, when the connecting plate 2 is pulled in the opposite direction to separate from the first connecting frame 1, since the locking block 304 flips in the opposite direction and cannot shrink as a whole into the inside of the connecting rod 302, it can cooperate with the connecting cavity 303 under the action of the locking block 304 to prevent the two from separating, thereby achieving preliminary positioning, facilitating subsequent installation, and strengthening the connection strength between the two.

[0021] like Figure 1-Figure 6 As shown, the anti-loosening component 4 includes a bolt 401 arranged on the inner side of the first connecting frame 1, one end of the bolt 401 passes through two interconnected connecting holes 102 in sequence and a nut 402 is threadedly connected to the surface, and the end of the bolt 401 away from the nut 402 is fixedly connected to a connecting block 405.

[0022] A groove coaxially arranged with the connecting hole 102 is provided on the surface of the connecting plate 2, and a resistance-increasing pattern is provided on the inner wall of the groove. The nut 402 covers the groove, and a resistance-increasing block 404 is slidably connected to the inner wall of the nut 402. The resistance-increasing block 404 is a rubber material component, and one end of the resistance-increasing block 404 passes through the nut 402 and extends to the inside of the groove.

[0023] One end of the resistance increasing block 404 away from the connecting plate 2 is fixedly connected to the first spring 403 , and the other end of the first spring 403 is fixedly connected to the inner wall of the nut 402 .

[0024] An adjustment cavity is provided on the inner wall of the connecting block 405, and a locking rod 407 is slidably connected to the inner wall of the adjusting cavity. A second spring 406 is fixedly connected between one end of the locking rod 407 and the inner wall of the adjusting cavity. The inner wall of the first connecting frame 1 is fixedly connected with evenly distributed mounting blocks 408, and locking holes are provided on the surface of the mounting blocks 408. The other end of the locking rod 407 passes through the connecting block 405 and extends to the interior of the adjacent locking hole.

[0025] During the installation process, after the initial positioning is achieved through the reinforcing component 3, the bolt 401 is passed through the two connected connecting holes 102 and the nut 402 is installed. During this process, as the nut 402 approaches the connecting plate 2, the resistance-increasing block 404 can be inserted into the interior of the groove and tightly fit against the resistance-increasing pattern. As the nut 402 approaches the connecting plate 2, the resistance-increasing block 404 can be squeezed under the obstruction of the inner wall of the groove and gradually retracted into the interior of the nut 402 and the first spring 403 is compressed until the nut 402 is tightly against the surface of the connecting plate 2. The squeezed first spring 403 can drive the resistance-increasing block 404 to be tightly against the inner wall of the groove under the elastic force, increasing the friction between the two, thereby reducing the loosening of the nut 402 due to the influence of vibration. During the installation of the bolt 401, the locking rod 407 is pressed to shrink into the inside of the adjustment cavity. During this process, the second spring 406 can be squeezed until the locking rod 407 corresponds to the locking hole provided on the mounting block 408 after the bolt 401 is installed in place. After the locking rod 407 is loosened, the locking rod 407 can be driven to pass through the locking hole under the action of the second spring 406, so that the position of the mounting block 408 can be limited, so that the bolt 401 can be limited to prevent its self-rotation, thereby avoiding the loosening phenomenon caused by the self-rotation of the bolt 401 due to vibration, and improving the anti-seismic effect; Furthermore, under the action of the reinforcing component 3, when the bolt 401 breaks, the connecting rod 302 cooperates with the connecting cavity 303 as a support to enhance the stability of the overall connection, compared with the existing structure in which the first connecting frame 1 and the second connecting frame 101 are separated after the bolt 401 breaks.

[0026] After the first connecting frame 101 is installed on the second connecting frame 101, the locking block 304 is first pressed to make it retract into the interior of the connecting rod 302, and then the connecting rod 302 is aligned with the docking hole on the connecting plate 2 and inserted into the connecting rod. During this process, the inner wall of the docking hole can squeeze the locking block 304 to keep it retracted into the interior of the connecting rod 302 until it is installed in place. At this time, the locking block 304 can be located at the connecting cavity 303, and under the resetting action of the spring 305, the rotating shaft 306 drives the locking block 304 to flip and insert into the interior of the connecting cavity 303. At this time, when the connecting plate 2 is pulled in the opposite direction to separate from the first connecting frame 1, the locking block 304 cannot be retracted into the interior of the connecting rod 302 as a whole due to the reverse flipping, and can cooperate with the connecting cavity 303 to prevent the two from separating, thereby achieving preliminary positioning, facilitating subsequent installation, and strengthening the connection strength between the two. After the preliminary positioning is achieved through the reinforcing component 3 during the installation process, the bolt 401 is passed through the two connected connecting holes 102 and the screw Cap 402. During this process, as nut 402 approaches connecting plate 2, resistance increasing block 404 can be inserted into the interior of the groove and fit tightly against the resistance increasing pattern. As nut 402 approaches connecting plate 2, resistance increasing block 404 can be squeezed and gradually retracted into nut 402 and first spring 403 can be compressed under the obstruction of the inner wall of the groove until nut 402 fits tightly against the surface of connecting plate 2. The squeezed first spring 403 can drive resistance increasing block 404 to fit tightly against the inner wall of the groove under the elastic force, increasing the friction between the two and reducing the loosening of nut 402 due to vibration. After installation, locking rod 407 corresponds to the locking hole on mounting block 408. After locking rod 407 is loosened, locking rod 407 can be driven through the locking hole under the action of second spring 406, thereby limiting the position of mounting block 408, realizing limiting the bolt 401 to prevent its rotation, avoiding the loosening caused by rotation of bolt 401 due to vibration, and improving the anti-seismic effect.
