Detailed Description

The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic views illustrating the basic structure of the present utility model by way of illustration only, and thus show only the constitution related to the present utility model.

Referring to fig. 1-4, a reinforcement protection layer spacer block comprises a spacer block body 1 and a reinforcement 3, wherein the elastic limiting component 2 above the spacer block body 1, the elastic limiting component 2 comprises an extending portion 21, an annular portion 22 and an elastic plastic clamp 23, the extending portion 21, the annular portion 22 and the elastic plastic clamp 23 are integrally formed and are fixed on the spacer block body 1 through the extending portion 21, and the reinforcement 3 is placed inside the annular portion 22 and the elastic plastic clamp 23 and is clamped by the annular portion 22 and the elastic plastic clamp 23. The cushion block body 1 is a concrete block and is integrally in an inverted prismatic table shape, the extension part 21 is poured in the cushion block body 1, the extension part 21, the annular part 22 and the elastic plastic clamp 23 are integrally formed, and the annular part 22 and the elastic plastic clamp 23 are arranged above the cushion block body 1.
