Detailed description of the invention:
Embodiment: see Fig. 2, 3, shown in 4, a kind of L shape anticracking plastic sheet be applied in L shape concrete prefabricated board, comprise the plastics main leaf 1 of L-type, two lateral surfaces of plastics main leaf 1 are fixed with several T-shaped anchor poles 2, splinter bar 3 is provided with between the anchor pole 2 of two lateral surfaces of plastics main leaf 1, splinter bar 3 is by backstay 31, first point of pole 32 and second point of pole 33 form, on the lateral surface that backstay 31 is fixed on position, plastics main leaf 1 right angle and with two lateral surfaces of the plastics main leaf 1 at place all in 135 ° of angles, first point of pole 32 and second point of pole 33 are separately fixed in the middle part of backstay 31 with on the two side of outer end.
The length of the dual-side of described plastics main leaf 1 is equal, plastics main leaf 1 is provided with many row's anchor poles 2 and splinter bar 3, anchor pole 2 and splinter bar 3 are vertically evenly distributed on plastics main leaf 1, and anchor pole 2 is provided with multiple row, and anchor pole 2 is laterally evenly distributed on plastics main leaf 1 lateral surface at anchor pole 2 place.
Described anchor pole 2 is perpendicular with plastics main leaf 1 lateral surface at anchor pole 2 place.
First point of pole 32 and second point of pole 33 of described splinter bar 3 are all T-shaped and perpendicular with backstay 31, and the length of first point of pole 32 is less than the length of second point of pole 33.
The two sides of described anchor pole 2 are perpendicular or form several sawtooth, and the two sides of first point of pole 32 and second point of pole 33 are perpendicular or form several sawtooth.
Operating principle: shown in composition graphs 5, its L shape anticracking plastic sheet is arranged in L-type concrete slab 4, its plastics main leaf is positioned at the L shape angle of cut mouth place of L-type concrete 4, the bonding strength at L-type concrete L shape angle of cut mouth place can be improved, and anchor pole 2 can reduce the relative displacement in both directions of L shape concrete slab side, splinter bar 3 can offset the tensile stress of a part of inside concrete, thus the crack 41 shown in Fig. 1 can be prevented, simultaneously at anchor pole 2, in there being sawtooth on the side of first point of pole 32 and second point of pole 33, increase anchor pole 2, first point of pole 32 and second point of pole 33 and concrete contact area, indirect reinforcement and concrete bonding strength.
