Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The utility model provides a blocking device for a cantilever steel beam through-wall hole, which comprises an inner side template 1, an iron wire 3 and a prefabricated plate 4, wherein the inner side template 1 and the prefabricated plate 4 are respectively positioned on the inner side wall and the outer side wall of a hole 6 and are connected together through the iron wire 3, as shown in figures 1, 2 and 3. Adopt iron wire 3 to draw and connect, have the advantage of being convenient for draw materials, practice thrift the cost. The outer side wall of the hole 6 is provided with an inward concave rabbet 7, and the precast slab 4 is placed in the rabbet 7.

The inner side template 1 comprises a vertical section and an inclined section, the inclined section is integrally formed at the top of the vertical section, and as shown in figure 1, the vertical section is provided with a through hole for accommodating an iron wire 3; the tip is less than entrance to a cave 6 under the slope section, the upper end of slope section is higher than entrance to a cave 6, and its effect is convenient for to pouring concrete in entrance to a cave 6, prevents the concrete outflow.
