Referring to fig. 50, according to the embodiment of the present application, a plurality of transverse holes 211 may also be longitudinally disposed on the front wall of the second preform 200, and the transverse holes 211 communicate with the front wall and the rear wall of the second preform 200 for achieving a connection function opposite to the opening of the first gap of the first preform.

51-52 illustrate a splice schematic of a cruciform shear wall assembly according to an example embodiment of the present application.

As shown in fig. 51 to 52, according to the present embodiment, the connection between the first preform 100 and the second preform 200 may be performed in various ways, and the first preform and the second preform having at least one pair of tie bars 103 may be connected to the preform having a single tie bar by at least one third connecting member 107. Or the first prefabricated member and the second prefabricated member with at least one pair of tie bars 103 are connected through at least one third connecting piece 107, wherein 1 third connecting piece is arranged on two pairs of tie bars in the first prefabricated member 100 and the second prefabricated member 200, or 2 third connecting pieces are arranged on two pairs of tie bars in the first prefabricated member 100 and the second prefabricated member 200, and then 2 third connecting pieces are bound together by a plurality of longitudinal bars 105.

Referring to fig. 52, one aspect of the splicing process of the cross-shaped shear wall assembly is described as follows, first preparing the first prefabricated member 100 and the second prefabricated member 200, clamping at least one pair of tie bars 103 of the first prefabricated member 100 to hide at least one third connecting member 107 in the first gap 101 of the first prefabricated member so that the at least one third connecting member does not extend out of the side wall of the first prefabricated member, pushing the at least one third connecting member 107 out of the first gap 101 after the openings of the first gap 101 and the second gap 201 are oppositely arranged, entering the second gap of the second prefabricated member to rest on the tie bars, and if necessary, arranging at least one longitudinal bar between the at least one third connecting member 107 and the at least one pair of tie bars (not shown); pouring concrete into the first gap and the second gap, wherein the distance between the first prefabricated part and the second prefabricated part is 0-30 mm, or 30-100 mm, or the other distance; the specific size of the third gap is determined according to the stress requirement, the construction convenience and the like.
