Detailed Description
Examples
As shown in fig. 1 to 3, a cantilever type prefabricated parapet connection construction; the prefabricated parapet comprises a prefabricated parapet 1 positioned on a roof, a prefabricated beam 2, a composite floor slab 3 and a prefabricated column 4;
the prefabricated parapet 1 is arranged on the prefabricated beam 2, between the two prefabricated columns 4, the lower part of the prefabricated parapet is in a step-shaped structure which is provided with a parapet lower outer leaf plate 5 towards the outer side and is provided with an inwards concave cast-in-place area towards the inner side;
the cast-in-place area is provided with a plurality of ribs 6 extending downwards to the precast beam 2;
a plurality of inclined reinforcing ribs 7 are arranged at the positions, close to the cast-in-place area, of the inner side surface of the prefabricated parapet 1;
one end of each oblique reinforcing rib 7 is pre-embedded in the prefabricated parapet 1, and the other end of each oblique reinforcing rib is poured on a superposed cast-in-place layer 11 of the superposed floor slab 3;
a plurality of matched drawing die embedded parts 8 are uniformly distributed at the joint between the bottom of the outer side of the outer leaf plate 5 at the lower part of the parapet wall and the upper part of the outer side of the precast beam 2;
the positions of the inner side of the prefabricated parapet 1, which are close to the two ends, are connected with the prefabricated columns 4 which extend upwards out of the prefabricated beam 2 through temporary angle steel and temporary fixing embedded parts 9.
The principle of the invention is as follows:
because the parapet is low in height and long in the longitudinal direction, the cantilever type stress mode is the most economical and reasonable scheme, the conventional prefabricated parapet scheme usually adopts a single-row steel bar sleeve connection at the lower part, and adopts a three-edge stress mode of a cast-in-place constructional column at two sides, so that the parapet is complex in stress, and the parapet is difficult to meet the requirement of larger subsection due to small thickness, thereby causing the parapet to be small in subsection and dense in cast-in-place constructional column, needing constructional column steel bar binding and field grouting on the spot, and increasing the field construction cast-in-place workload and the construction difficulty.
The invention starts from an economic and reasonable stress mode of the parapet, realizes the cantilever stress mode of the prefabricated parapet, realizes large segmentation of prefabricated components, and reduces the workload of site cast-in-place and the construction difficulty.
In some embodiments, a PE rod and waterproof sealant 10 is provided between the upper surface of the precast beam 2 and the lower end surface of the parapet lower outer leaf panel 5.
In some embodiments, a plurality of U-shaped tendons 12 are provided in the cast-in-place area.
In some embodiments, the plurality of ribs 6 and the plurality of U-shaped ribs 12 are staggered with respect to each other.
In some embodiments, the upper ends of both prefabricated columns 4 at both ends of prefabricated parapet 1 are flush with prefabricated parapet 1.
In some embodiments, prefabricated parapet 1 is provided with a plurality of stripper inserts 13 on the inside.
In practical application, after the prefabricated columns 4 on the roof, the prefabricated beams 2 and the composite floor slabs 3 are installed in place, the cantilever type prefabricated parapet 1 is hoisted, after the position and the verticality of the prefabricated parapet 1 are adjusted, the prefabricated parapet is placed in place, the lower part ribs 6 of the prefabricated parapet 1 are inserted into the U-shaped inserting ribs on the upper part of the prefabricated beams 2, the end parts of the prefabricated parapet 1 and the side surfaces of the prefabricated columns 4 on two sides are fixedly connected through temporary angle steel and temporary fixing embedded parts 9, the prefabricated beams 2 and the outer side die drawing embedded parts 8 of the prefabricated parapet 1 are connected through temporary channel steel, the reinforcing steel meshes of the composite floor slabs 3 on the roof are bound, oblique reinforcing steel bars on the lower part of the prefabricated parapet 1 and the reinforcing steel meshes of the composite floor slabs 3 are bound together, and then concrete of the composite floor slabs 3 is poured, so that the lower part reinforcing steel bars of the prefabricated parapet, the prefabricated beams 2 and the composite floor slabs 3 form an integral structure.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts.
