Detailed Description
The present invention will be further described with reference to the following examples and the accompanying drawings.
Example 1
The double-layer bidirectional concrete cushion block comprises a concrete triangular table and side edges 1 of the triangular table.
Referring to fig. 1, fig. 1 is a schematic view illustrating a structure of a double-deck bidirectional concrete pad according to an embodiment of the present invention. As shown in the figure, the concrete triangular table is an atypical triangular table, the top surface and the bottom surface of the triangular table are triangular, the triangular shape of the top surface is small, and the triangular shape of the bottom surface is large; two adjacent side surfaces of the atypical triangular table are respectively provided with an arc-shaped groove capable of holding a steel bar, and the axes of the two arc-shaped grooves are mutually vertical. Wherein: the width of the steel bar placing part of the upper layer and the lower layer is 15mm, and the concrete surface slightly sinks downwards by 2-3mm, so that the steel bars do not fall off after being placed. During manufacturing, the smooth round steel bar is pressed and formed. The total height of the cushion block is set according to the thickness of a floor slab, in the thickness of 120mm, the height of the cushion block is 100mm, the placing position of the lower steel bar is 15mm away from the lower slab surface, and the placing position of the upper steel bar is 10mm away from the top surface of the cushion block; the whole height of the cushion block is 20mm smaller than the thickness of the structural concrete floor slab, and the thickness of a protective layer of the upper-layer steel bar is ensured.
