Problems solved by technology

[0002] The steel strand tensioning of pre-tensioned prestressed components must be constructed on prefabricated pedestals with top columns. The construction of pedestals requires a lot of work and a large one-time investment. Therefore, fixed pedestals are generally used in prefabricated factories and cannot be relocated. The application is limited by the transportation radius of heavy components, resulting in small service radius, poor production balance of components, and high amortization cost of prefabrication plants, so the production cost of components is generally high
A pre-tensioned prestressed goose-shaped slab mold with a removable top column and side formwork has not been reported yet.

Embodiment Construction

[0022] see Figure 1 to Figure 6 , The present invention provides an embodiment of a pre-tensioned prestressed geese plate mold, including a side form 1, a bottom form 3, and an end prestressed anchor beam 2 and an anchor plate 4. The side form 1 is formed by longitudinal splicing of several block-shaped special-shaped side forms, the special-shaped side form is a composite plate of steel plate and concrete, and the bottom form 3 is formed by longitudinally segmented splicing of several rectangular reinforced concrete beams. The present invention is used to manufacture the pre-tensioned prestressed geese-shaped slab by the long-line method, and the side mold 1 and the bottom mold 3 in the geese-shaped slab mold are both used as the bottom mold 3 of the prefabricated geese-shaped slab and as the tensioning part of the prestressed steel strand. For the top column, due to the long length of the overall formwork, the side form 1 and the bottom form 3 are assembled in sections for ...

Abstract

The invention provides a pretensioning method prestressed bird-shaped plate die which comprises a side die, a bottom die, an end prestressed reinforcement anchoring beam and an prestressed reinforcement anchoring plate and is characterized in that the side die is longitudinally spliced by a plurality of heteromorphic side plates, the heteromorphic side plates are composite plates of steel plates and concrete, and the bottom die is longitudinally spliced by a plurality of rectangular reinforced concrete beams in a segmented way. According to the pretensioning method prestressed bird-shaped plate die provided by the invention, the side die adopts a high-strength steel-concrete combination plate, and the bottom die adopts reinforced concrete, so that the plate die can be used as templates of the bird-shaped plate and can be also used as prestress tensioning support pillar; and as a prefabricated tensioning pedestal which can be detachably transported is adopted, the pretensioning method prestressed bird-shaped plate die can be conveniently transported according the business needs.

Description

technical field [0001] The invention relates to a concrete prefabricated component mold, in particular to a movable mold for manufacturing pretensioned prestressed geese-shaped slabs. Background technique [0002] The steel strand tensioning of pre-tensioned prestressed components must be constructed on prefabricated pedestals with top columns. The construction of pedestals requires a lot of work and a large one-time investment. Therefore, fixed pedestals are generally used in prefabricated factories and cannot be relocated. The application is limited by the transportation radius of heavy components, resulting in small service radius, poor production balance of components, and high amortization cost of prefabrication plants, so the production cost of components is generally high. A pre-tensioned prestressed geese-shaped slab mold with a removable top column and side mold has not been reported yet. Contents of the invention [0003] The technical problem to be solved by th...
