[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] like Figure 1-7 As shown, a reinforcement structure of a steel structure crossbeam includes a crossbeam 1 and a longitudinal beam 2, and a socket 24 is opened on the longitudinal beam 2;

[0028] An angle bracket 3 is provided at the connection between the cross beam 1 and the longitudinal beam 2, and is provided with an insertion rod 31 which is plugged into the socket 24;

[0029] The pressing rod 33 disposed on the insertion rod 31 is rotated. In the plugged state, the pressing rod 33 is pressed and deflected by the socket 24 to abut against the inner wall of the longitudinal beam 2 .

[0030] Specifically, a plurality of threaded holes are provided on the angle code 3, and a wide opening 241 for accommodating the pressure rod 33 is provided on the socket 24. When reinforcing the cross beam 1 and the longitudinal beam 2, the staff can hold the angle code 3 with one hand, so that the insertion rod 31 is inserted into the longitudinal beam 2 along the socket 24, and the pressure rod 33 enters the interior of the longitudinal beam 2 along the wide opening 241. At the same time, the pressure rod 33 is blocked by the socket 24 during the insertion process, so the pressure rod 33 is deflected to pass through the socket 24. At the same time, the pressure rod 33 presses the inner wall of the longitudinal beam 2, so that the position of the angle code 3 is fixed. The staff does not need to continue to hold it, and can free both hands to align the bolts with the threaded holes on the angle code 3, and tighten the bolts to fix them.

[0031] In the above technology, through the design of the pressure rod 33, the staff can insert the angle code 3 into the longitudinal beam 2 with one hand. During the insertion process, the pressure rod 33 is deflected to press the inner wall of the longitudinal beam 2, so that the position of the angle code 3 is fixed. The staff does not need to continue to hold it, and can free both hands to align the bolt with the threaded hole on the angle code 3, and tighten the bolt to fix it.

[0032] As an embodiment further provided by the present invention, a transmission rod 34 is arranged on the rotation shaft of the pressure rod 33 , and the transmission rod 34 and the pressure rod 33 are perpendicular to each other and staggered along the axis of the rotation shaft.

[0033] Specifically, a torsion spring 35 is provided on the transmission rod 34 to maintain a predetermined angle with the side wall of the angle code 3, so that the transmission rod 34 remains perpendicular to the outer wall of the insertion rod 31. During the plugging process, the transmission rod 34 moves with the insertion rod 31 toward the socket 24, so that the transmission rod 34 is blocked by the socket 24 and deflected, so that the transmission rod 34 is deflected from being perpendicular to the outer wall of the insertion rod 31 to being close to the outer wall of the insertion rod 31, so that the transmission rod 34 can pass through the socket 24 and drive the pressure rod 33 to deflect and press the inner wall of the longitudinal beam 2. Since an elastic metal piece 331 is provided at the end of the pressure rod 33, it bends and deforms as the pressure rod 33 presses the inner wall of the longitudinal beam 2. At this time, the elastic force of the elastic metal piece 331 increases the force on the longitudinal beam 2, further fixing the position of the angle code 3, and a plurality of rollers 242 are provided on the socket 24 to prevent the socket 24 from causing damage to the pressure rod 33.

[0034] As another embodiment further provided by the present invention, a slot 21 for slidingly assembling with the insertion rod 31 is fixedly provided inside the longitudinal beam 2 .

[0035] Specifically, when the angle bracket 3 is inserted into the longitudinal beam 2 along the socket 24 , the insertion rod 31 is slidably assembled in the slot 21 , and the friction between the insertion rod 31 and the slot 21 prevents the insertion rod 31 from falling out, thereby limiting the position of the angle bracket 3 .

[0036] As another embodiment further provided by the present invention, a push plate 22 which can be pushed out by the insertion rod 31 is inserted into the slot 21 , and the push plate 22 is used to limit the pressing rod 33 .

[0037] Specifically, as the insertion rod 31 is inserted into the slot 21, the inclined surface set at the end of the insertion rod 31 slides into the slot 21, and the push plate 22 is pushed by the inclined surface and slides along the inclined surface to extend along the width direction of the slot 21. At this time, the pressure rod 33 has been pressed against the inner wall of the longitudinal beam 2. Therefore, the push plate 22 is pressed against the pressure rod 33 during the extension process, so that the position of the pressure rod 33 is restricted, thereby preventing the pressure rod 33 from rotating.

[0038] As another embodiment further provided by the present invention, a locking groove 32 is provided on the insertion rod 31 , and an inclined block 23 for mutually locking with the locking groove 32 is provided on the push plate 22 .

[0039] Specifically, a plurality of springs are arranged between the push plate 22 and the slot 21. The inclined surface at the end of the insertion rod 31 pushes the inclined block 23, so that the inclined block 23 slides along the inclined surface and drives the push plate 22 to extend along the width direction of the slot 21. The spring is stretched and elastic energy is stored. Then the inclined block 23 moves into the locking groove 32. When the inclined block 23 is not blocked by the inclined surface, it rebounds under the elastic force of the spring and makes the inclined block 23 enter the locking groove 32, so that the slot 21 and the insertion rod 31 are locked with each other, thereby achieving the fixation of the diagonal code 3.

[0040] Working principle: When reinforcing the cross beam 1 and the longitudinal beam 2, the staff can hold the angle code 3 in one hand, so that the insertion rod 31 is inserted into the longitudinal beam 2 along the socket 24. During the insertion process, the transmission rod 34 moves along the insertion rod 31 toward the socket 24, so that the transmission rod 34 is blocked by the socket 24 and deflected, so that the transmission rod 34 is deflected from being perpendicular to the outer wall of the insertion rod 31 to being close to the outer wall of the insertion rod 31, so that the transmission rod 34 can pass through the socket 24 and drive the pressure rod 33 to deflect and press the inner wall of the longitudinal beam 2. Since the end of the pressure rod 33 is provided with an elastic metal piece 331, it bends and deforms as the pressure rod 33 presses the inner wall of the longitudinal beam 2. At this time, the elastic force of the elastic metal piece 331 increases the force on the longitudinal beam 2. The rod 31 is then slidably assembled in the slot 21, and the friction force between the rod 31 and the slot 21 plays a role in preventing the rod 31 from falling off. The inclined surface at the end of the rod 31 pushes the bevel block 23, causing the bevel block 23 to slide along the inclined surface and drive the push plate 22 to extend along the width direction of the slot 21. The spring is stretched and elastically stores energy, and then the bevel block 23 moves into the locking groove 32. When the bevel block 23 is not blocked by the inclined surface, it rebounds under the elastic force of the spring, and causes the bevel block 23 to enter the locking groove 32, so that the slot 21 and the rod 31 are locked with each other, thereby achieving the fixation of the diagonal code 3. The staff does not need to continue to hold it, and can free both hands to align the bolts with the threaded holes on the angle code 3, and tighten the bolts to fix it.

[0041] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
