Abstract

A height-adjustable assembly-type prefabricated concrete composite floor slab comprises angle steel, steel bar trusses, L-shaped screw rods, concrete and nuts. A component A1 is composed of the anglesteel, the concrete and the steel bar trusses jointly, and holes are reserved in the two sides of the beam direction of a prefabricated plate; the component A1 is manufactured in a factory and assembled on site in a lifted mode; transverse rods of the L-shaped screw rods are hung on the upper surface of a beam, and vertical rods penetrate through the holes in the prefabricated plate and are screwed through the nuts; after lifting, the height of the prefabricated plate can be adjusted by adjusting the nuts on the L-shaped screw rods, the relative positions of floor slab bodies and the beam areadjusted, it is guaranteed that the lower surfaces of all the floor slab bodies are flush, and the lifting problem caused by the uneven surface of a concrete composed is solved; through the connectingmode, part of the beam depth is hidden, and the clear height of a structural layer is increased; the adhesive force of new and old concrete layers is increased through the steel bar trusses in the prefabricated plate, and the overall performance of the composite floor slab is improved; and the prefabricated plate and the beam are lifted on site through the L-shaped screw rods and the nuts, and the height-adjustable assembly-type prefabricated concrete composite floor slab conforms to the concept of assembly-type buildings.

Description

technical field

[0001] The invention belongs to the field of building structural components and is suitable for prefabricated concrete buildings. Background technique

[0002] Since 2015, the planning of prefabricated buildings has been intensively introduced. The "Industrialized Building Evaluation Standards" released at the end of 2015 decided to fully promote prefabricated buildings in 2016 and made breakthrough progress. The "Guiding Opinions on Vigorously Developing Prefabricated Buildings" issued by the State Council in 2016 requires the development of prefabricated concrete structures, steel structures and other prefabricated buildings according to local conditions to promote the adjustment and upgrading of industrial structures.

[0003] Precast concrete laminated slab refers to an assembled integral floor slab formed by superimposing the upper cast-in-place layer with precast concrete thin slabs at the bottom. This laminated floor slab has good integrity, high rigid...
