Embodiments of the reinforcement spacer of the present utility model are shown in fig. 1-3.
Example 1
The reinforcing steel bar cushion block of the embodiment is formed by mortar reverse molding. The steel bar cushion block comprises a supporting table 1 for separating an upper layer of steel bar and a lower layer of steel bar, wherein the supporting table 1 is formed by mortar reverse molding. The supporting table 1 is a round table with a small upper part and a large lower part, and the ratio of the diameter of the upper surface of the supporting table 1 to the diameter of the lower surface of the supporting table 1 is 2:3, so that the supporting table 1 is more stable. Two mutually perpendicular grooves I2 are formed in the upper surface of the supporting table 1 to accommodate upper-layer bidirectional reinforcing steel bars, and four grooves II 3 are formed in the lower surface of the supporting table 1 to avoid lower-layer bidirectional reinforcing steel bars so as to keep the supporting table 1 stable. The first groove 2 is an arc-shaped groove. The first groove 2 and the second groove 3 are blind grooves extending along the diameter direction of the upper surface and the lower surface of the supporting table 1, and the first groove 2 and the second groove 3 are respectively positioned at the corresponding positions of the upper surface and the lower surface of the supporting table 1. The first grooves 2 penetrate through the supporting table 1 in the left-right direction and the front-back direction respectively, the second grooves 3 are respectively positioned at two ends of two mutually perpendicular diameters of the lower surface of the supporting table 1, and the lengths of the second grooves 3 are consistent with the thickness of the hollow table 5 at the lower part of the supporting table 1.
The upper part of the supporting table 1 is a solid table 4, and the lower part is a hollow table 5 so as to reduce mortar required for pouring the reinforcing steel bar cushion blocks. The height of the upper solid table 4 of the supporting table 1 is adjusted according to the requirement, and the thickness of the lower hollow table 5 of the supporting table 1 is more than or equal to 10mm. The hollow part of the lower part of the supporting table 1 is in a round table shape 。
