Description
Technical Field
The invention relates to the field of buildings, in particular to a connection process of a reserved open-hole type partially-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. In order to solve the processing difficulty of the special-shaped PEC composite shear wall and avoid the weak point of the external stability of the wall surface of the straight shear wall, so that the special-shaped PEC composite shear wall is convenient to process, produce and splice on site and meets the structural design performance requirements, therefore, the inventor further researches the special-shaped PEC composite shear wall and develops a connection process of a reserved open-cell type partially-coated concrete composite shear wall, and the scheme is generated.
Disclosure of Invention
In order to achieve the purpose, the technical scheme of the invention is as follows:
a reserved hole type connecting process of a partially-coated concrete combined shear wall comprises the steps of welding a web plate and a wing plate to form an I shape serving as a long wall limb and a steel skeleton of a short wall limb in a factory, welding a bottom plate and side edges to form a U-shaped channel steel serving as a connecting beam, vertically arranging one side plate of the connecting beam and the web plate of the short wall limb and welding and fixing the side plate and the web plate of the short wall limb, arranging bolt holes in the long wall limb side wing plate and the connecting beam bottom plate after multiple times of calibration, transporting the long wall limb, the short wall limb and the connecting beam to a construction site, carrying out site hoisting and splicing, aligning connecting holes between the wing plate of the long wall limb and the bottom plate of the connecting beam, fastening bolts, spot-welding and reinforcing at a splicing part and a contact part, and finally pouring.
The long wall, the short wall and the connecting beam can be prefabricated in a factory, then the wing plates of the long wall and the connecting holes between the bottom plates of the connecting beams are aligned when the site construction is carried out, the bolts are fastened, the weak point of external stability of the straight-line-shaped shear wall is avoided, the straight-line-shaped shear wall is convenient to process, produce and splice on site, the structural design performance requirements are met, and the straight-line-shaped wall can be kept lying flat and stacked for transportation during transportation.
Furthermore, the connecting holes on the wing plate of the long wall limb are uniformly distributed on two sides of the web plate.
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 reserved open-hole type partially-coated concrete combined shear wall comprises a long wall limb, a short wall limb and a connecting beam, 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 to form an I shape, and a cell formed by the wing plates and the web plate is filled by pouring concrete; the connecting beam comprises a bottom plate and side plates, the bottom plate and the side plates on the two sides form a U-shaped structure, connecting holes which correspond to each other are formed in the bottom plate of the connecting beam and the wing plates on the side edges of the long wall limbs, and the bottom plate of the connecting beam and the connecting holes in the wing plates on the side edges of the long wall limbs are connected through connecting pieces; one side plate of the connecting beam and the web plate of the short wall limb are vertically arranged and welded and fixed.
After adopting the scheme, compared with the prior art, the invention has the following advantages:
the processing difficulty of the special-shaped combined shear wall is solved, the outer stability weakness of the wall surface of the straight shear wall is avoided, the processing production and the field splicing are facilitated, and the structural design performance requirement is met.
