一种钢筋保护层厚度和钢筋间距控制的混凝土垫块
摘要：
本实用新型公开了一种钢筋保护层厚度和钢筋间距控制的混凝土垫块，包括条形混凝土垫块，预埋钢丝和半圆钢筋定位槽3。其特征在于：在条形混凝土垫块（1）上面沿长度方向均布半圆钢筋定位槽（3），每个半圆钢筋定位槽附近预埋钢丝（2），预埋钢丝（2）将钢筋绑扎在半圆钢筋定位槽（3）内，固定钢筋半圆钢筋定位槽（3）的直径与将要固定的钢筋直径相同，半圆钢筋定位槽（3）之间的间距与将要固定的钢筋的间距相同。半圆钢筋定位槽（3）最低点至条形混凝土垫块（1）对边的宽度为钢筋保护层厚度。本实用新型不仅准确的控制钢筋保护层厚度，还能准确控制钢筋之间的间距，成本低，安装方便，施工速度快。
摘要（英）：

The utility model discloses a concrete cushion of cover to reinforcement thickness and bar spacing control, including bar concrete cushion, pre -buried steel wire and semicircle steel bar locating groove 3. Its characterized in that: along length direction equipartition semicircle steel bar locating groove (3) on bar concrete cushion (1), near every semicircle steel bar locating groove pre -buried steel wire (2), pre -buried steel wire (2) with reinforcement in semicircle steel bar locating groove (3), fixed reinforcing bar semicircle steel bar locating groove's (3) diameter is the same with the bar diameter that will fix, the interval between the semicircle steel bar locating groove (3) is the same with the interval of the reinforcing bar that will fix. The width of semicircle steel bar locating groove (3) minimum to bar concrete cushion (1) opposite side is cover to reinforcement thickness. The utility model discloses accurate control cover to reinforcement thickness not only, interval between can also accurate control reinforcing bar, it is with low costs, simple to operate, construction speed is fast.
