Description
Technical Field
The invention relates to the field of buildings, in particular to a connecting process of an inner push bolt type coated concrete composite shear wall.
Background
China vigorously pushes the traditional building to be transformed into an industrialized building. In the traditional building, most of work needs to be finished on a construction site, and the problems of long construction period, serious environmental pollution, large stacking field, shortage of constructors and the like become barriers for inhibiting the progress of the building industry. The partially-coated concrete composite shear wall (PEC shear wall) is produced by an industrial production line, concrete is directly poured into a semi-open cavity defined by a steel flange and a steel web, no additional template is needed for pouring on a mold table, and the construction speed is high. The straight shear wall has weaker external stability, so that the shear walls adopted in practical engineering are mostly L-shaped and T-shaped, so that the wall limbs mutually provide external constraint to ensure the stability, and the PEC combined shear wall limb splicing part with the special shape can bring greater difficulty for pouring if an integral prefabrication process that all the wall limbs are welded firstly and then poured is adopted. The special-shaped PEC shear wall aims to solve the processing difficulty of the special-shaped PEC shear wall and avoid the weak point of stability outside the wall surface of the straight shear wall, so that the special-shaped PEC shear wall is convenient to process, produce and splice on site, meets the structural design performance requirements, and is beneficial to the development of a PEC shear wall structural system. Therefore, the inventors of the present invention have further studied this and developed a connecting process of an inner push bolt type clad concrete composite shear wall, and the present invention has been made from the above.

a technology for connecting the internal push bolt type composite shear wall coated with concrete features that the web plate and wing plate are sequentially welded together to form an I-shaped steel skeleton, the long wall limb and the short wall limb are formed by pouring and filling concrete in the cells formed by the wing plates and the web plates, the web plate of a certain cell of the long wall limb and the wing plate at the side edge of the short wall limb are provided with a plurality of corresponding connecting holes, the positions of the connecting holes of the long wall limb and the connecting holes of the short wall limb are calibrated for a plurality of times during manufacture, and after the wing plate of the short wall limb is arranged in the cell of the long wall limb, the connecting holes of the long wall limb web plate and the connecting holes of the short wall limb wing plate can be connected through bolts, after the long wall limb and the short wall limb are transported to a construction site, and (4) carrying out on-site hoisting and splicing, aligning the flange of the short wall limb with the embedded bolt to the reserved position of the connecting hole of the long wall limb, pushing the flange inwards until no gap exists, fastening the bolt, and finally pouring concrete on the other side of the web plate.
Can accomplish long wall limb and the prefabricate earlier of short wall limb in the mill, keep a style of calligraphy wall to lie flat during the transportation and pile up and transport, transport and hoist the concatenation after the scene to pour newly formed district check can.
Furthermore, the connecting holes of the long limb web plate and the connecting holes of the short limb wing plate are distributed in a plurality of areas with uniform intervals, the connecting holes in each area are two rows, and each row is provided with 4 connecting holes.
Too close spacing between the attachment holes will reduce the strength of the panels themselves, while too few attachment holes will reduce the strength of the attachment between the panels.
Furthermore, the push-in bolt type coated concrete combined shear wall comprises a long wall limb and a short wall limb, wherein the long wall limb and the short wall limb comprise a web plate and wing plates, the wing plates are vertically and fixedly arranged on two sides of the web plate, and the cells formed by the wing plates and the web plate are filled by pouring concrete; the web plate of a certain cell of the long limb and the wing plate at the side edge of the short limb are provided with a plurality of corresponding connecting holes, the wing plate of the short limb can be arranged in the cell of the long limb, and the connecting hole of the web plate of the long limb and the connecting hole of the wing plate of the short limb are connected through a connecting piece.
After adopting the scheme, compared with the prior art, the invention has the following advantages:
the long wall limb and the short wall limb can be prefabricated in a factory, the long wall limb and the short wall limb are hoisted and spliced on site, and the newly formed cells are poured, so that the key difficulty in manufacturing is solved, the manufacturing and transportation cost is reduced, and the processing, production and field splicing are facilitated.
