9. A method for using a prefabricated steel structure component, comprising the prefabricated steel structure component according to any one of claims 1 to 8, characterized in that: When in use, when fixing the support plate 1 (1) and the support plate 2 (11), the worker aligns the fixing plate (22) fixedly connected to one end of the outer surface of the support plate 2 (11) with the notch 2 (21) provided on the outer surface of the support plate 1 (1), and then controls the movement of the latch (42) and the control plate (35) to achieve the fixing and release of the support plate 1 (1) and the support plate 2 (11). The operation is simple, the use is convenient, and the support plate 1 (1) and the support plate 2 (11) can be reused for subsequent use. When it is necessary to fix the positions of the support plate 1 (1) and the support plate 2 (11), the support plate 2 (11) is pushed to make the fixing plate (22) slide to the inside of the slot 2 (21) and contact the inclined surface of the fixing block (25), and the support plate 2 (11) is continued to be pushed to drive the fixing block (25) to slide to the inside of the slot 3 (23). When the fixing plate (22) contacts the plane position of the fixing block (25), the fixing block (25) is reset under the elastic force of the slot 3 (23), thereby fixing the position of the fixing plate (22), and then achieving the fixing of the positions of the support plate 1 (1) and the support plate 2 (11). When it is necessary to release the fixing of the support plate 1 (1) and the support plate 2 (11), the latch (42) is pulled to make the latch (42) disengage from the inside of the socket (43) and compress the spring 3 (41), and then The sliding control plate (35) drives the slide plate (31) and the control block (32) fixedly connected to the slide plate (31) to slide synchronously and stretch the second spring (33), the control block (32) contacts the inclined surface of the fixed block (25), and then pushes the fixed block (25) to slide into the inside of the third notch (23), so that the fixed block (25) and the inner side surface of the third notch (23) are fitted together, and the latch (42) is inserted into the inside of the right plug hole (43) under the elastic force of the third spring (41), thereby achieving the fixation of the relative position of the control plate (35) and the fixed plate (22), at which time the vertex of the inclined surface of the fixed plate (22) contacts the vertex of the inclined surface of the fixed block (25), pulling the second support plate (11) to drive the fixed plate (22) to slide out from the inside of the second notch (21), thereby releasing the fixation of the first support plate (1) and the second support plate (11); When it is necessary to reinforce the support plate 1 (1) and the support plate 2 (11), the latch (42) is pulled to disengage the latch (42) from the inside of the socket (43) and compress the spring 3 (41), and then the control plate (35) is pushed to drive the connecting rod (513) to move synchronously to the left. Because the rotating block 2 (510) is slidably connected to the limiting rod 2 (59), and the connecting rod (513) is slidably connected to the sliding groove 3 (512), the movement of the connecting rod (513) drives the rotating plate 2 (511) and the rotating block 2 (510) to rotate around the center of the rotating block 2 (510), so that the rotating block 2 (510) is The plane of the rotating block (510) is rotated to a horizontal position, and the rotation of the rotating block (510) drives the plane of the rotating block (53) to rotate to a horizontal position and compress the tension spring (56), and the latch (42) is released so that the latch (42) is inserted into the inside of the right plug hole (43) under the elastic force of the spring (41), and the position of the control plate (35) is fixed, thereby fixing the relative positions of the rotating block (510) and the control block (32) and the fixed plate (22), and then the supporting plate (11) is pushed to drive the fixed plate (22) to be inserted into the notch (21), and the connecting block (57) is inserted. The first connecting block (5) is inserted into the fixing hole in the support plate (1), and the second connecting block (57) is inserted into the fixing hole on the surface of the second connecting block (57). The latch (42) is pulled to release the fixation of the control plate (35). The fixing block (25) is reset under the elastic force of the first spring (24). At the same time, the slide plate (31) drives the control plate (35) to move in the opposite direction to reset under the elastic force of the second spring (33). The first connecting block (54) drives the rotating block (53) to rotate in the opposite direction under the elastic force of the tension spring (56). The rotation of the rotating block (53) drives the rotating block (510) to rotate synchronously. The plane positions of the rotating block 1 (53) and the rotating block 2 (510) that are in contact with each other are rotated to a certain angle, thereby fixing the connecting block 1 (5) and the connecting block 2 (57) inside the fixing hole. At this time, the position of the latch (42) coincides with the position of the left insertion hole (43). Under the elastic force of the spring 3 (41), the latch (42) is inserted into the inside of the insertion hole (43) to fix the position of the control board (35), thereby achieving the fixing effect of the supporting plate 1 (1) and the supporting plate 2 (11). When it is necessary to release the reinforcement of the supporting plate 1 (1) and the supporting plate 2 (11), the reverse operation can be performed.
