Among the above-mentioned technical scheme, the base is U type structure, including connecting portion and supporting part, the connecting hole has been seted up on the connecting portion, the both ends of connecting portion respectively with two supporting part transitional coupling, two the supporting part laminates and fixed connection with prefabricated staircase mould baffle, the base is the integrated into one piece structure.
Among the above-mentioned technical scheme, the backing plate includes the straight portion of both ends and two base laminatings to and the middle arch portion that is used for connecting fixed positioning element, arch portion is domes, and with straight smooth and smooth transitional coupling of portion, the connecting hole has all been seted up with two straight portions to arch portion, and setting element fastening bolt, backing plate fastening bolt all pass it and correspond the connecting hole and fix backing plate and setting element locking on the base, the backing plate is the integrated into one piece structure.
In the above technical solution, the lower portion of the positioning member further has a tapered shoulder.
In the above technical scheme, the positioning piece is a nylon rod.
In the technical scheme, the base is fixed on the stair mold baffle by welding or bolt connection.
In the technical scheme, the gasket is arranged at the large end of the cross section of the positioning piece, the gasket is a disc with a bolt through hole in the center, the diameter of the disc is larger than that of the large end of the cross section of the positioning piece, and the gasket and the positioning piece can be of an integrally formed structure.
The utility model has the advantages that:
because the mounting hole of prefabricated stair is reserved to the mode that adopts pre-buried rod iron when prefabricated stair in prior art, but the rod iron is stronger to the concrete adsorptivity, so after the prefabricated stair concrete sets up the shaping, the rod iron can only be knocked out from the top with the sledge hammer, and intensity of labour is big, and the rod iron drawing of patterns is difficult, and the rod iron is knocked out the back and reserves the mounting hole collapse edge and fall the angle phenomenon seriously moreover, not only influences the product quality of prefabricated stair, need increase repair man-hour moreover. The utility model discloses at first the design has the base, with base welding or bolt fastening on the mould flange of prefabricated stair, then pass through setting element fastening bolt with setting element and backing plate and lock on the base, when will prefabricated stair cast concrete initial set simultaneously, be about to the mould flange of prefabricated stair with the utility model discloses a base leaves, then easily takes out the setting element. Therefore, the utility model discloses a setting element drawing of patterns is easy, and the mould not damaged, the fashioned installation hole of drawing of patterns is smooth not have the limit that collapses and fall the angle, and pleasing to the eye of high quality need not the repair, has saved man-hour, has improved efficiency.
