[0002] A building is a structure of two or more stories, and during its construction, various reinforcement bars, structural bars, and negative reinforcement are used. Negative reinforcement, also known as negative moment reinforcement, is used to resist negative bending moments in reinforced concrete structures. These bars typically refer to the upper edges of floor slabs. Due to their size, these bars can easily come into contact with other reinforcement bars, leading to errors.

[0003] Currently, various types of spacers have been designed to facilitate the separation of rebar at different locations. For example, the utility model patent with authorization announcement number CN205743031U discloses a multi-interface negative reinforcement spacer, which secures rebar at different locations via two stepped fixing holes at the upper end of the main body. However, due to the small size and weight of the spacer itself, and the shallow depth of the fixing holes on the side of the spacer, it is easy for the spacer to tilt or fall sideways during actual construction, causing unnecessary trouble and affecting the construction progress.

[0004] Therefore, it is urgent to design a stirrup pad with a simple structure and good stability. Utility Model Content

[0007] Furthermore, the notch step surface, the intersection between the upper groove surface and the side wall of the pad block body, and the intersection between the upper groove surface and the lower groove surface are all set as arc transition surfaces.

[0008] Furthermore, the outer contour of the longitudinal section of the pad block body is a trapezoidal structure, and the pad block body is integrally cast by concrete.

[0009] Furthermore, the height of the cushion block body is 65-85 mm, and the height between the lower groove surface and the bottom surface of the cushion block body is 20-25 mm.

[0010] The utility model also discloses a block mold for making a two-in-one stirrup block, comprising a lower mold and an upper mold for casting a block body, wherein the lower mold is provided with a plurality of block mold grooves matching the block body, and the plurality of block mold grooves are evenly distributed in multiple rows; the arrangement direction of the plurality of block mold grooves in the same row and in alternate rows is consistent, and the arrangement direction of the two corresponding block mold grooves in adjacent rows is rotated 180 degrees;
