Embodiment Construction

[0020] see figure 1 , figure 2 In this embodiment, the structural form of the wall tie-bar member that is pre-embedded and then mechanically cold-connected is to set a pre-embedded structure in the concrete member 5, and the pre-embedded structure is fixed and welded on the member stressed steel bar 2 in the member 5. A pair of positioning steel bars 1, the wire sleeve 3 is spot welded and fixed between the pair of positioning steel bars 1; the tie bar 6 is connected with the wire sleeve 3 by the end of the wire; the matching device is composed of a cap and a plug head The plastic blocking member 4 is blocked on the outer end of the threaded sleeve 3 by the plastic blocking member 4 and can be disassembled.

[0021] In this embodiment, the wall tie-bar members that are pre-embedded and then mechanically cold-connected are installed according to the following process:

[0022] 1. Reliably weld the positioning steel bar 1 and the structural member stressed steel bar 2, and th...

Abstract

The invention discloses an after-embedding mechanical cold connection wall body drawknot rib construction member and an installation method. The installation method is characterized in that an embedding structure is arranged in a concrete construction member; the embedding structure is characterized in that one pair of spacer bars is fixedly welded on the stressed reinforcement of the construction member in the construction member; a threading sleeve is fixedly arranged between the pair of spacer bars in a spot welding mode; the drawknot rib is in screwed connection with the threading sleeve by the end thread of the drawknot rib; a plastic plugging piece formed by a nut cap and a plug is arranged for matching; and the drawknot rib is plugged on the outer end of the threading sleeve by the plastic plugging piece and is detachable. According to the invention, the construction quality of the drawknot rib can be effectively controlled, and the embedding work is easier to implement.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a wall tie-bar member which is pre-embedded and then mechanically cold-connected and an installation method thereof. Background technique [0002] During construction, especially in areas with significant earthquake loads, the specification stipulates that tie bars are used to connect the infill wall and its surrounding related components, including beams, columns and other structural components. Its function is to connect the infill wall with the surrounding components as a whole to improve the lateral stiffness of the structure, and rely on the tie bars to constrain the infill wall to effectively resist earthquakes. At present, there are two commonly used methods in wall construction. One is the method of pre-embedding the tie bars: one end of the tie bars is pre-buried in the concrete, then drilling holes are drilled on the side formwork of the column, and the other end...
