[0043] The bottom of the laminated floor 21 is provided with two groups of second guide grooves 28, and the two groups of second guide grooves 28 are symmetrically arranged with the center axis of the laminated floor 21 as the center. The bottom of the laminated floor 21 is slidably connected with a partition plate 29, the cross-sectional size of the partition plate 29 is the same as that of the first guide groove 26, and the partition plate 29 is slidably connected to the inner wall of the first guide groove 26. The surface of the partition plate 29 is provided with a polyurethane coating. The top of the partition plate 29 is fixedly connected with two groups of linkage blocks 210, and the two groups of linkage blocks 210 are both penetrated by a guide rod 211. A spring is sleeved on the guide rod 211, and the spring is in abutting connection between the inner wall of the second guide groove 28 and the linkage block 210. One end of the guide rod 211 is fixedly connected to the inner wall of the second guide groove 28. The two groups of linkage blocks 210 are slidably connected to one side of the inner wall of the second guide groove 28. The outer walls of the two groups of linkage blocks 210 are both fixedly connected with a limiting block 212, and the end of the limiting block 212 is not in contact with the other side of the inner wall of the second guide groove 28.

[0055] After the cast-in-place layer concrete 5 is solidified, the screws in the screw embedded holes 14 are sequentially removed at the bottom of the aluminum formwork 11, then the end of the reset pull rope 216 is pulled to move the isolation plate 29 to the bottom of the laminated floor 21, and the laminated floor 21 is pushed in the direction of the end of the steel bar body 6 to separate the laminated floors 21 on both sides from the rectangular groove 12 and the hollow sliding cavity 13, so that the aluminum formwork leak-proof structure can be taken out after the cast-in-place layer concrete 5 is solidified, and the steel bar body 6 is embedded in each other after the cast-in-place layer concrete 5 is solidified, so that the aluminum formwork leak-proof structure can be repeatedly used.

A method of constructing an aluminum form leakproofing paste construction of the fabricated building according to claim 1, characterized by: The construction method comprises: The positioning plate is slidably connected to the inner wall of the rectangular groove and the hollow sliding cavity through the laminated floor; The end of the screw is threadedly and tightly connected to the internal threaded hole in the positioning plate through the screw-embedding hole for placing the screw; The tool for rotating the bolt is inserted into the internal multi-rib hole at the end of the bolt, so that the first sliding block and the second sliding block are moved in opposite directions when the bolt is rotated; When the first sliding block and the second sliding block move in opposite directions, the limiting rod is driven to separate the end of the limiting rod from the limiting block, and the spring tension of the guide rod elastically abuts against the linkage block, so that one end of the isolation plate penetrates through the first guide groove and extends to the upper surface of the aluminum formwork to seal the hollow sliding cavity and the plurality of screw-embedding holes; The two groups of laminated floor mechanisms are symmetrically arranged on both sides of the aluminum formwork, and the spring tension of the guide rod in each laminated floor mechanism maintains the sealing property of the spliced ends of the two isolation plates; The screws in the screw-embedding holes at the bottom of the aluminum formwork are sequentially disassembled, the end of the reset pull rope is pulled, the isolation plate is moved to the bottom of the laminated floor, the laminated floor is pushed in the direction of the end of the reinforcing bar body, the laminated floors on both sides are separated from the rectangular groove and the hollow sliding cavity, the aluminum formwork leak-proof structure is removed after the cast-in-place layer concrete is solidified, and the cast-in-place layer concrete is embedded with the reinforcing bar body after being solidified.
