Detailed Description
The principles and features of the present invention are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the invention and are not to be construed as limiting the scope of the invention.
A spacer block (see fig. 1 and 2) for controlling the thickness of a reinforcement cover and a floor slab, comprising an H-shaped prefabricated block and two plastic clips 3; the precast block is formed by two symmetrical side plates 1 and a transverse plate 2 which are integrally cast by mortar or concrete; the transverse plate 2 is arranged in the middle between the two side plates 1, and an upper steel bar groove and a lower steel bar groove are formed between the two side plates 1 and the transverse plate 2; the plastic clamp 3 comprises a bottom plate 3.1, an inclined plate 3.2 connected with the bottom plate 3.1, a clamping plate 3.3 on the same side of the top of the inclined plate 3.2 and the bottom plate 3.1, a clamp limiting plate 3.4 arranged in the middle of the inclined plate 3.2, and an embedded plate 3.5 arranged on the bottom plate 3.1; the pre-buried board 3.5 is pour in the bottom of prefabricated section, and swash plate 3.2 is located the lower steel bar inslot of prefabricated section, and two plastics clamp symmetry are installed.
On the basis of the embodiment, the cushion block can be further improved and the data parameters are limited:
At least two embedded plates 3.5 are arranged.
