8. A construction method for a steel structure roof structure with a replaceable waterproof layer according to claim 7, characterized in that, Includes the following steps: Step 1: Install the roof frame Multiple support rods (2) and connecting rod 1 (4) are spliced ​​together. The support rods (2) and connecting rod 1 (4) are fixed together by the first bolt (5). A support column (3) is fixedly connected below the support rod (2) to support the frame structure. Mounting rods (10) are installed at both ends of the support rod (2). A fixed shaft (11) is snapped onto one side of the mounting rod (10). The mounting rod (10) and the fixed shaft (11) are snapped and fixed onto the support rod (2) by the snapping mechanism. The upper ends of the two fixed shafts (11) are provided with rails (8). When the fixed shaft (11) and the mounting rod (10) are connected to the support rod (2), the L-shaped block (26) is directly passed through both sides of the fixed shaft (11) and mounted on the surface of the mounting rod (10). The protrusion (30) on the inner wall of the L-shaped block (26) is engaged with the groove (29) and fixed. The I-shaped block (27) is installed from below the support rod (2). The two ends of the I-shaped block (27) are engaged with the side of the U-shaped block (31) and the side of the L-shaped block (26) respectively. Finally, the threaded shaft (28) is threaded through the I-shaped block (27), the U-shaped block (31), and the L-shaped block (26). The nut is used to fix the connection between the fixed shaft (11), the mounting rod (10), and the support rod (2). Step 2, Installation of waterproof membrane (1) and connecting rod 2 (7) Connecting rods 2 (7) are attached to both ends of the waterproof membrane (1), and one of the connecting rods 2 (7) is attached to the arc groove at one end of the track (8). The two ends of the other connecting rod 2 (7) are fitted with connecting sleeves (12) and rotatedly connected with the connecting rod 2 (7). The slot 1 (13) is fixed at one end of the connecting sleeve (12). Step 3: Installation of drive mechanism and connecting mechanism Two rollers (17) are mounted on the movable block (15) via bearings (18). The rollers (17) are rolled on the lower inner wall of the slide groove (9). A top shaft (16) is mounted on the movable block (15) and the top shaft (16) is slidably fitted on the upper inner wall of the slide groove (9). A micro motor is placed on the bottom block (32) of the moving block (15). The micro motor deflects the top of the two clamping blocks (22) by acting on the bottom of the two clamping blocks (22). Finally, the micro motor is clamped by the spring piece (25). After the drive end of the micro motor is inserted into the second slot (23), the second bolt (24) is threaded through to fix and limit the position. Step 4, Install the waterproof membrane (1) The drive end of the micro motor drives the second slot (23) to rotate, the second slot (23) drives the second gear (21) to rotate, the second gear (21) meshes with the first gear (20), the second gear (21) will drive the first gear (20) to rotate, the first gear (20) will drive the connected roller (17) to rotate, the two rollers (17) are connected together through the linkage shaft (19), so the two rollers (17) will rotate synchronously, realizing the movement effect of the moving block (15) relative to the slide (9), and then the connecting rod (7) can be driven to move from one end of the track (8) to the other end, covering the entire upper position of the frame with the waterproof membrane (1). When the moving block (15) moves to the last position, the connecting rod (7) will be locked in the arc groove opened on the track (8) for fixation. After the waterproof membrane (1) is laid, the connecting sleeve (12) and the first slot (13) are removed from both ends of the connecting rod (7). Step 5, Replace the waterproof membrane (1): The drive end of the micro motor drives the second slot (23) to rotate in the opposite direction, thereby removing the waterproof membrane (1) and the second connecting rod (7) from the track (8), reinstalling the second connecting rod (7) with the waterproof membrane (1), inserting one of the second connecting rods (7) into the arc groove at one end of the track (8), fitting the two ends of the other second connecting rod (7) with the connecting sleeve (12) and rotating it with the second connecting rod (7), fixing the first slot (13) at one end of the connecting sleeve (12), and repeating step 4 to complete the replacement operation.
