Description
Technical Field
The utility model relates to a building field refers in particular to a reservation trompil formula partial cladding concrete composite shear wall's joint construction.
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, the inventor of the invention further researches the special-shaped PEC composite shear wall and develops a connection structure of a reserved open-cell type partially-coated concrete composite shear wall and a construction method thereof.
SUMMERY OF THE UTILITY MODEL
In order to achieve the above purpose, the technical solution of the present invention is as follows:
a connection structure of a reserved open-hole type partially-coated concrete combined shear wall comprises a long wall limb, a short wall limb and a connection 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.
The long wall limb, the short wall limb and the connecting beam can be prefabricated in a factory, then the connecting holes between the wing plates of the long wall limb and the bottom plates of the connecting beams are aligned when the site construction is carried out, the through bolts are fastened, and finally the splicing part and the contact part are reinforced by spot welding.
Further, the connecting piece is a bolt.
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.
After the scheme is adopted, compared with the prior art, the utility model, have following advantage:
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.

The wall comprises a long wall limb 1, a short wall limb 2, a connecting beam 3, a web plate 4, wing plates 5, a bottom plate 6, side plates 7 and connecting holes 8.
Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in the figure, the connection structure of the reserved open-hole type partially-coated concrete combined shear wall comprises a long wall limb 1, a short wall limb 2 and a connecting beam 3, wherein the long wall limb 1 and the short wall limb 2 both comprise a web plate 4 and wing plates 5, the wing plates 5 are vertically and fixedly arranged (or formed by welding or integral pouring and forging forming) to form I shapes on two sides of the web plate 4, the wing plates 5 and the web plate 4 form a plurality of cells, and the cells are filled with concrete through pouring.
The connecting beam 3 comprises a bottom plate 6 and side plates 7, the bottom plate 6 and the side plates 7 on two sides form a U-shaped structure, connecting holes 8 which correspond to each other are formed in the bottom plate 6 of the connecting beam 3 and the wing plates 5 on the side edge of the long wall limb 1, and the bottom plate 6 of the connecting beam 3 and the connecting holes 8 on the wing plates 5 on the side edge of the long wall limb 1 are connected through bolts; one side plate 7 of the connecting beam 3 and the web 4 of the short wall limb 2 are vertically arranged and welded, so that the long wall limb 1 and the short wall limb 2 form an L-shaped structure. The connecting holes 8 on the wing plates 5 of the long wall limbs 1 are uniformly distributed on two sides of the web plates 4, the strength of the plates is reduced when the connecting holes 8 are spaced too close, and the connecting strength between the plates is reduced when the connecting holes 8 are too few.
A construction method of a reserved open-hole type combined shear wall comprises the following steps:
