The upper frame is correspondingly provided with an ear plate with a notch, the lower frame is correspondingly hinged with a screw and nut assembly, and a screw of the screw and nut assembly is screwed into the notch of the ear plate and is locked through a nut.

The grout stopping ring is formed by welding reinforcing steel bars, and is evenly divided into four sections at intervals at the lower die hole, and the intervals correspond to the lower rope penetrating holes one by one.

The utility model relates to a can end D type concrete interlocking piece prefabricated template of thick liquid has following technological effect: by arranging the grout stopping ring, the grout leakage problem caused by untight closing caused by the deformation of the die can be improved, the grout leakage rate is greatly reduced, and the grout stopping effect is obvious. Furthermore, due to no slurry leakage, the generation of concrete block fins is reduced, and the overall prefabrication quality of the concrete interlocking block is effectively improved. The improved point has low cost, can be completed only by welding, greatly improves the production efficiency and reduces the production cost.

Detailed Description

As shown in fig. 1-2, a D-shaped precast concrete interlocking block formwork capable of stopping grout comprises an upper die 1 and a lower die 2.

As shown in fig. 3-4 and 7, the upper die 1 includes an upper frame 3, an upper die plate 4 is arranged in the upper frame 3, the upper die plate 4 is formed by splicing a plurality of unit blocks, an upper die hole 5 is formed in the center of each unit block, and an upper rope passing hole 6 with a semicircular cross section is formed in the lower bottom surface of each unit block and transversely and longitudinally passes through the center of the upper die hole 5.

As shown in fig. 5-6, the lower die 2 includes a lower frame 7, a lower die plate 8 is disposed in the lower frame 7, the lower die plate 8 is formed by splicing a plurality of unit blocks, a lower die hole 9 is formed in the center of each unit block, a lower rope passing hole 10 with a semicircular cross section is formed in the center of the lower die hole 9 in the horizontal and longitudinal direction in the upper bottom surface of each unit block, and the upper rope passing hole 6 and the lower rope passing hole 10 are in one-to-one correspondence and are combined into a circular hole. The round hole can be penetrated by the rope.
