Embodiment
[0027] The vertical main reinforcement connecting device of the assembled wall column member provided in this embodiment is arranged on two opposite vertical main reinforcements of the assembled wall column, and is used for connecting the two vertical main reinforcements. Specifically, such as figure 1As shown, the wall column components in this embodiment include an upper wall column component and a lower wall column component, and a plurality of upper vertical steel bars are correspondingly provided in the upper wall column component 1 and the lower wall column component 2 respectively. 3 and the lower vertical reinforcement 4 (i.e. the vertical main reinforcement), there are a plurality of reserved blind holes corresponding to the upper vertical reinforcement 3 in the upper wall column member 1, and each lower end of the upper vertical reinforcement 3 1. The upper end of each lower vertical steel bar 4 is provided with a prefabricated thread of the same specification; each ...

The invention discloses a vertical main rib connection device of an assembled wall column component and an installation method thereof. The connection device comprises an inner sleeve with a first thread on the inner wall and an outer sleeve with a second thread on the inner wall; the The inner sleeve is cylindrical, and the outer wall of the inner sleeve is provided with arc-shaped protrusions with the same tooth pattern at axial intervals; An arc-shaped groove for the arc-shaped protrusion to slide up and down is formed between each two adjacent inner-cylinder connecting parts, which can be engaged with the inner cylinder connecting part through the tooth pattern; when the arc-shaped protrusion and the arc-shaped groove are connected When there is a one-to-one correspondence, the outer sleeve and the inner sleeve are in an unlocked state. When the arc-shaped projections are in one-to-one correspondence with the inner cylinder connecting portion and engaged, there is a gap between every two adjacent arc-shaped projections and the inner cylinder connecting portion. An arc-shaped through groove is formed, and an arc-shaped clamping piece tightly matched with the arc-shaped through groove is arranged in the arc-shaped through groove, so that the outer sleeve and the two inner sleeves are in a locked state.
Description
technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a vertical main reinforcement connecting device of a prefabricated wall column component and an installation method thereof. Background technique [0002] The prefabricated shear wall is generally composed of an upper wall column member and a lower wall column member, and the upper and lower wall column members are connected by vertical steel bars arranged in the upper wall column member and the lower wall column member. During production, a plurality of reserved holes are provided in the upper wall column member, and the vertical steel bars in the lower wall column member are inserted into the corresponding reserved holes, and are sealed by grouting after welding or socket fitting. The method of grouting after the sleeve connection has high requirements for the construction workers, and it is inconvenient to promote. The structural strength of the welded connection is gua...
