Spring 2043, a clamping rod 2044 is installed on the second assembly plate 103, and the clamping rod 2044 and the clamping block 2041 correspond horizontally, and the surface of the clamping block 2041 is chamfered; the rotation of the bidirectional screw shaft drives the screw sleeve to slide, and the synchronous plate and the push plate on the screw sleeve drive the push rod to move toward the second assembly plate as a whole. After the clamping block on the push rod touches the clamping rod, the clamping block moves up by itself. When the clamping block passes over the clamping rod, the clamping block is driven to move down by the internal extrusion spring to lock the clamping rod, so that the X-axis direction of the first assembly plate and the second assembly plate are positioned and locked.

[0046] The Z-axis direction positioning unit 300 includes a guide plate 301, which is rotatably mounted on the first assembly plate 102, a guide protrusion 3012 is mounted at an eccentric position of the guide plate 301, and a strip plate 302 is slidably mounted on the guide protrusion 3012, a rocker arm 3023 is movably mounted at the end of the strip plate 302, and the end of the rocker arm 3023 is movably connected to the screw sleeve 202, a guide plate 303 is mounted on the side wall of the guide plate 301, and a slope 3031 is mounted on the guide plate 303, a fixed block 304 is slidably mounted on the slope 3031, a top column 305 is mounted on the fixed block 304, and the top of the top column 305 is vertically mounted on the second assembly plate 103. Corresponding to plate 3051, a cover 3053 is installed on the surface of the second assembly plate 103, and the cover 3053 covers the outer side of the first assembly plate 102; during the sliding process of the screw sleeve, the position of the rocker arm on the screw sleeve changes, pulling the synchronization rod at the end of the rocker arm to move inward, and the strip plate on the synchronization rod pushes the eccentric guide protrusion to move, thereby driving the guide plate to rotate as a whole, and the position of the guide plate on the guide plate changes, thereby lifting the fixed block as a whole to move upward, and the top column on the fixed block and the L-shaped plate on the second assembly plate fit tightly and squeeze each other, and at this time the cover is synchronously covered on the first assembly plate, thereby completing the Z-axis direction positioning and locking of the first assembly plate and the second assembly plate.

[0047] The Y-axis direction positioning unit 400 includes a squeeze plate 401, which is connected to the synchronization rod 3022.

The convex rod drives the insert block at the end to be inserted into the gap between the two positioning blocks, completing the Y-axis direction locking operation of the first assembly plate and the second assembly plate.

[0048] like Figure 1 and Figure 2 As shown, in a specific embodiment, a support column 1011 is installed on the base 101, and a flat plate 1012 is installed on the top of the support column 1011, a mounting plate 104 is provided on the first assembly plate 102 and the second assembly plate 103, and the mounting plate 104 and the flat plate 1012 are screwed together and connected by bolts, and a water guide groove 1041 is provided at the bottom of the first assembly plate 102 and the second assembly plate 103. The mounting plate 104 and the flat plate 1012 are installed with each other to ensure that the first assembly plate 102 and the second assembly plate 103 are connected with the base 101, and the water guide groove 1041 is used to facilitate the discharge of water.

[0049] Embodiment 2: Based on the above embodiment 1, the difference between this embodiment and the present embodiment is as follows: Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, mounting seats 2011 are rotatably installed at both ends of the bidirectional screw shaft 201, and the mounting seats 2011 are welded to the back of the first assembly plate 102, a turntable 2012 is installed at the end of the bidirectional screw shaft 201, a knob 2013 is installed on the turntable 2012, and an anti-slip groove is arranged on the surface of the knob 2013, a slide plate 2021 is installed on the screw sleeve 202, a limit rod 2022 is arranged inside the slide plate 2021, and both ends of the limit rod 2022 are installed on the side walls of the mounting seat 2011, and a protective cover 1021 is installed at the bottom of the first assembly plate 102. Then the operator needs to turn the knob 2013, and the knob 2013 drives the turntable 2012 to rotate. The anti-skid groove on the knob 2013 increases the friction force, making the rotation easier. After the turntable 2012 rotates, the bidirectional screw shaft 201 is driven to rotate on the mounting seat 2011, and the rotation of the bidirectional screw shaft 201 drives the screw sleeve 202 to slide (because the slide plate 2021 at the bottom of the screw sleeve 202 slides on the limit rod 2022 at this time, and then the rotation of the screw sleeve 202 is limited, and then the screw sleeve 202 slides horizontally at this time.

[0050] like Figure 8 , Fig. 9 and Fig.10 As shown, further, a baffle 2042 is slidably provided inside the push rod 204, one end of the baffle 2042 is interconnected with the block 2041, and an extrusion spring 2043 is clamped between the other end of the baffle 2042 and the inner cavity of the push rod 204, the compression direction of the extrusion spring 2043 and the moving direction of the block 2041 are on the same straight line, and a push plate 2032 is installed on the back of the push rod 204, and the push plate 2032 and the push rod 2031 are interconnected. The synchronous plate 203 and the push plate 2032 on the screw sleeve 202 drive the push rod 204 to move as a whole toward the second assembly plate 103. After the inclined surface of the block 2041 on the push rod 204 touches the clamping rod 2044, the block 2041 moves up by itself, and the baffle 2042 on the block 2041 slides upward synchronously, which can squeeze the extrusion spring 2043. When the block 2041 passes over the clamping rod 2044, the internal extrusion spring 2043 drives the block 2041 to move down, and the clamping rod 2044 is locked, so that the X-axis direction of the first assembly plate 102 and the second assembly plate 103 are positioned and locked.

[0051] Embodiment 3: Based on the above embodiment 2, the difference between this embodiment and the present embodiment is as follows: Figure 4 , Figure 5 and Figure 6 As shown, a rotating shaft 3011 is installed at the center of the guide plate 301, and the rotating shaft 3011 is rotatably installed on the first assembly plate 102, a strip groove 3021 is provided on the strip plate 302, and the strip groove 3021 and the guide protrusion 3012 are slidably connected, and a limit seat 3024 is movably inserted on the synchronization rod 3022, and the limit seat 3024 is installed on the first assembly plate 102. When the synchronization rod 3022 moves inward, the synchronization rod 3022 slides toward the center along the limit seat 3024, and the position of the strip plate 302 on the synchronization rod 3022 changes synchronously, and the strip groove 3021 on the strip plate 302 pushes the guide protrusion 3012 to move, and the guide protrusion 3012 slides on the strip groove 3021, and then the guide protrusion 3012 installed eccentrically can drive the guide plate 301 to rotate around the rotating shaft 3011 as a whole.

[0052] like Figure 4 , Figure 5 and Figure 6As shown, in a specific embodiment, a connecting rod 3041 is installed at the bottom of the fixed block 304, a guide wheel 3042 is installed at the end of the connecting rod 3041, the guide wheel 3042 is slidably connected to the guide plate 303, a positioning sleeve 3052 is movably inserted at the bottom of the top column 305, and the positioning sleeve 3052 is welded and set on the first assembly plate 102, and bolt holes are vertically opened on the top column 305 and the L-shaped plate 3051. During the rotation of the guide plate 301, the position of the guide plate 303 on the guide plate 301 changes, and the guide plate 303 moves to the bottom of the guide wheel 3042. At this time, the slope 3031 can continuously lift the connecting rod 3041 and the fixed block 304 to slide upward, and the top column 305 on the fixed block 304 and the L-shaped plate 3051 on the second assembly plate 103 are closely fitted and squeezed against each other, and bolts are installed in the bolt holes to complete the fixing operation.

When the fixed block 304 slides, the positioning plate 3043 on the side wall of the fixed block 304 slides on the positioning rod 3044, and the limiting plate 3045 can ensure that the positioning plate 3043 and the positioning rod 3044 are not separated, and when the positioning plate 3043 slides, the return spring 3046 can be compressed, and the return spring 3046 is convenient for the later reset process.

A protrusion 4031 is installed on the convex rod 403, and the protrusion 4031 is slidably arranged in the combination groove 402, and a positioning seat 4032 is slidably arranged on the side wall of the convex rod 403, and the positioning seat 4032 is welded on the first assembly plate 102, and the bolt holes opened on the surfaces of the plug block 404 and the positioning block 4041 correspond to each other. When the synchronization rod 3022 slides inward, the synchronization rod 3022 drives the extrusion plate 401 to move. At this time, the extrusion plate 401 slides along the insertion rod 4011 and squeezes the positioning spring 4012. The positioning spring 4012 facilitates the later resetting operation. At this time, the protrusion 4031 on the protruding rod 403 slides on the inclined groove 4021 of the combination groove 402. Through the guiding effect of the inclined groove 4021, the protruding rod 403 is pushed to move outward along the positioning seat 4032 as a whole. The protruding rod 403 drives the plug block 404 at the end to be inserted into the gap between the two positioning blocks 4041, and the locking operation is performed by the bolt, completing the locking operation of the first assembly plate 102 and the second assembly plate 103 in the Y-axis direction.

[0055] The present invention also discloses a construction method of a prefabricated assembled slope roof system, the steps of which are as follows:

[0056] Step 1: Connect the side walls of the first assembly plate 102 and the second assembly plate 103 to each other;

[0057] Step 2: Rotate the bidirectional screw shaft 201, the rotation of the bidirectional screw shaft 201 drives the screw sleeve 202 to slide, and the synchronous plate 203 and the push plate 2032 on the screw sleeve 202 drive the push rod 204 to move toward the second assembly plate 103 as a whole, and after the block 2041 on the push rod 204 touches the card rod 2044, the block 2041 moves up by itself, and when the block 2041 passes over the card rod 2044, the block 2041 is driven to move down by the internal extrusion spring 2043, and the card rod 2044 is locked, so that the X-axis direction positioning of the first assembly plate 102 and the second assembly plate 103 is locked;
