Abstract

The invention discloses a precise centring die device for a prefabricated concrete structure grouting sleeve. The precise centring die comprises a slideway, two sets of steel frames, a sleeve positioning shaft roller, a protruding bar positioning shaft roller and fixing nuts. The two sets of steel frames are oppositely arranged on the prefabricated part production line slideway in a parallel manner. Each steel frame set comprises two side steel plates and a cross steel plate, wherein the cross steel plate is arranged between the two side steel plates, and the cross steel plate is provided with a plurality of rows of small holes. One end of the sleeve positioning shaft roller penetrates the small holes of the cross steel plate of one steel frame set and is fixed to the corresponding cross steel plate through the corresponding fixing nut, and the other end of the sleeve positioning shaft roller extends into the grouting sleeve. One end of the protruding bar positioning shaft roller penetrates the small hole of the cross plate of the other steel frame set and is fixed to the corresponding cross steel plate through the corresponding fixing nut, and the other end of the protruding bar positioning shaft roller is in a tubular shape and is inserted into a protruding bar. The precise centring die device can ensure centring of the prefabricated concrete unit sleeve and the protruding bar in a high-precision manner, the site construction difficulty is lowered, and the connection quality of the prefabricated concrete structure grouting sleeve is practically guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of production and installation of building concrete components, and in particular relates to a precise centering mold device for an assembled concrete structure grouting sleeve. Background technique

[0002] At present, in my country's prefabricated prefabricated concrete building structures, grouting sleeve connection is one of the main forms of connection of various components. recommend. In actual engineering practice, the alignment accuracy of the grouting sleeve connection in the production process of prefabricated components is insufficient, which easily leads to the difficulty of prefabricated construction. According to statistics, the accurate alignment ratio of the sleeve and the extended steel bar in the actual project is about 20% or so.

[0003] The centering accuracy of the sleeve and the corresponding connecting extended steel bar is too low, which may cause two problems. First, it is difficul...
