Detailed Description
The invention will be further explained with reference to the drawings and the specific embodiments.
Referring to the attached drawings 1 and 3, the post-pouring vertical seam stressed key for the prefabricated ring plate of the wind power tower barrel comprises a stressed key main body groove 1 and a groove 2; the stress key main body groove 1 is concavely arranged on the vertical joint splicing surface of the ring piece 3, and the stress key main body groove 1 vertically penetrates through the ring piece 3 along the height direction of the ring piece 3; the grooves 2 are concavely arranged on the vertical joint splicing surface of the ring piece 3, and the grooves 2 are distributed at intervals along the radial direction of the stress key main body groove 1 and are communicated with the stress key main body groove 1; after the adjacent ring pieces 3 are spliced, the stress key main body grooves 1 and the grooves 2 on the adjacent ring pieces 3 are correspondingly spliced into stress key groove bodies respectively, and the stress keys are formed after slurry is poured into the stress key groove bodies, so that the stress keys and the ring pieces 3 are connected into an integral structure.
Referring to fig. 2 and 4, the cross section of the groove 2 is a polygonal structure, and the surface of the groove 2 is provided with a first inclined surface structure 4, so that demolding is facilitated.
The upper end and the lower extreme of atress key main part groove 1 all be equipped with the constant head tank, a pair of registration arm 6 of assembling matches respectively and inlays the dress in the constant head tank, is convenient for play the positioning action when adjacent ring piece 3 is assembled, makes to assemble more accurately.
The cross section of constant head tank be semi-circular structure, and the internal diameter of constant head tank is equivalent with the external diameter of assembling registration arm 6, make to assemble registration arm 6 and inlay the dress just in two cylindrical grooves that the constant head tank concatenation formed, be convenient for assemble the location.
The cross section shapes of the stress key main body groove 1 and the groove 2 can be adjusted according to the actual splicing requirement, and the setting of a die is convenient.
Referring to fig. 1 and 2, example 1:
preferably, the cross section of the stress key main body groove 1 is of a semicircular structure, so that the stress key main body grooves 1 of the adjacent ring pieces 3 are spliced to form a cylindrical main body groove structure, a mold is convenient to match, and post-pouring of slurry is convenient.
Referring to fig. 3 and 4, example 2:
preferably, the cross section of the stress key main body groove 1 is of a rectangular structure, so that the stress key main body grooves 1 of the adjacent ring pieces 3 are spliced to form the rectangular main body groove structure, the matching of a mold is facilitated, and post-pouring of slurry is facilitated.
