Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
The utility model provides a pre-buried part of fixed stair rail, as shown in figure 1, including pre-buried board 1 and fixed sleeve 2, a plurality of fixed sleeve 2 are fixed admittedly to the inboard of pre-buried board 1, the pre-buried board 1 cross-section is the L type; the tail end of the fixed sleeve 2 is of a closed structure; a plugging piece is hermetically arranged at the port of the fixed sleeve 2; the embedded plate 1 is fixedly connected with the stair template 5 through a connecting piece. During construction, a stair template 5 is installed firstly, then the embedded plate 1 is fixedly installed in the stair template 5, and after the embedded plate 1 is fixed, a stair is poured; the sealing and blocking piece is arranged in the fixed sleeve 2, so that the concrete slurry can be prevented from flowing into the fixed sleeve 2 to cause blockage; preferably, the number of the fixing sleeves 2 is two; preferably, the fixing sleeve 2 is welded on the embedded plate 1. And after pouring is finished, the plugging piece in the fixed sleeve 2 is taken out, and the stair fence is fixed on the outer end face of the embedded plate 1 through the fixed bolt. In the pouring process, the embedded plate 1 is fixed with the stair template 5, so that firm positioning is realized, the positioning accuracy is improved, the subsequent stair fence can be conveniently installed, and the embedded plate 1 is effectively prevented from deviating under the extrusion of concrete slurry. The embedded plate 1 is installed on the front end face of the stair, is high in shearing resistance, and can firmly fix the stair fence on the stair, so that the stair fence is effectively prevented from loosening, and potential safety hazards are avoided.
