The specific embodiment
First embodiment
As shown in Figure 1 to Figure 3, shearing resistance part of the present utility model is a steel plate that thickness is 4-8mm, the upper end of steel plate has several to the staggered tooth wing 1 that curves an angle of 90 degrees of two edges of plate, there are several through holes that is arranged in a row 2 middle part of steel plate, the reinforced hole 3 of one row's circle is arranged in the zone of distance steel plate lower end 1/3, and its diameter is bar diameter+20mm to be worn, and its spacing is 100-250mm, the tooth wing 1 is a rectangle, and the width that curves the tooth wing of an angle of 90 degrees is 20-40mm.
Second embodiment
As shown in Figure 4, this embodiment and first embodiment are basic identical, and same section repeats no more.Different is that reinforced hole 3 is arranged in the steel plate lower end, and reinforced hole 3 is shaped as the arched door shape, its upstanding edge height 15～30mm, and semicircle diameter is bar diameter+20mm to be worn.
The 3rd embodiment
As shown in Figure 5, this embodiment and first embodiment are basic identical, and same section repeats no more.Different is that the tooth wing 1 is zigzag.
The 4th embodiment
As shown in Figure 6, this embodiment and first embodiment are basic identical, and same section is not repeated.The different tooth wings 1 be circular arc.
Though Fig. 1, Fig. 5 and Fig. 6 have only shown the tooth wing 1 of rectangle, zigzag and circular arc, in fact, the tooth wing 1 can be different shape, as: circular, oval or trapezoidal.
Though Fig. 1, Fig. 3 show reinforced hole 3 and are shaped as circle and arch door shape that in fact reinforced hole 3 shapes can be different shape, can be slotted hole shape, ellipse, the shape of a saddle etc.
