自动回弹马凳
摘要：
自动回弹马凳，用于将混凝土板中的上层钢筋网片支撑于下层钢筋网片上；所述的马凳包括第一支撑臂和第二支撑臂，第一支撑臂和第二支撑臂分别包括相对的第一端和第二端；第一支撑臂的第一端与第二支撑臂的第一端相互连接，并形成夹持槽；第一支撑臂的第二端设有第一支撑脚，第二支撑臂的第二端设有第二支撑脚，所述第一支撑脚与第一支撑臂之间的夹角及第二支撑脚与第二支撑臂之间的夹角都为20°～45°，第一支撑脚和第二支撑脚抵接于下层钢筋网片上，以使所述第一支撑臂与第二支撑臂支撑所述第二钢筋。该自动回弹马凳能够安全稳固地支撑混凝土板中上层钢筋网片，而且混凝土浇筑时踩踏下去后还能自动回弹起来，且后续混凝土浇筑后没有外露点。
摘要（英）：

Automatic resilience split heads for support the upper layer steel bar net piece among the concrete slab on lower floor's reinforcing bar net piece, the split heads include first support arm and second support arm, first support arm and second support arm include relative first end and second end respectively, the first end of first support arm and the first end interconnect of second support arm to form the centre gripping groove, the second end of first support arm is equipped with first supporting legs, and the second of second support arm is held and is equipped with the second supporting legs, contained angle between first supporting legs and the first support arm and the contained angle between second supporting legs and the second support arm all are 20~45, first supporting legs and second supporting legs butt on lower floor's reinforcing bar net piece so that first support arm supports with the second support arm the second reinforcing bar. This automatic resilience split heads upper layer steel bar net piece among the mounting spur concrete slab that can stabilize safely can also kick -back voluntarily after trampling down during concrete placement in addition, and not have outer dew point behind the follow -up concrete placement.
