Aiming at the problems, the embodiment of the utility model provides a top preformed structure for a constructional column reinforcement-free construction.
In one aspect of the embodiment of the utility model, a top preformed structure for a constructional column reinforcement-free construction is provided, and the top preformed structure comprises a precast concrete block and embedded bars which are arranged through the top surface and the bottom surface of the precast concrete block, wherein the bottom surface of the precast concrete block has the same size as the cross section of the constructional column; the upper half part of the precast concrete block, which upwards penetrates out of the embedded bars, is embedded in the main body structure floor slab, and the top surface of the precast concrete block is attached to the bottom surface of the main body structure floor slab.
Compared with the prior art, the utility model has the beneficial effects that: the top forming structure and the main structure floor slab are integrally constructed, so that a construction mode of embedding the constructional column steel bars in a non-planting manner is realized; and the pre-buried top forming structure forms a top space, which is a construction column top dustpan opening supporting and concrete pouring manufacturing operation space.
Optionally, the middle part and the upper half part of the embedded bar which are arranged in the precast concrete block are bent.
Optionally, the upper parts of a group of opposite side surfaces in the precast concrete segments are retracted inwards by a predetermined dimension to form an inner shrinkage surface, and a transition surface is obliquely arranged between the inner shrinkage surface and the lower part of the side surface.
Optionally, a constructional column steel bar framework is bound below the precast concrete block, and a vertical main bar and an embedded bar in the constructional column steel bar framework downwards penetrate out of the lower half part of the precast concrete block to be in lap joint.
