As shown in the figure, the utility model provides a horizontal bending-resistant beam joint structure for bolted-connected assembled reinforced concrete wall panels; the beam end steel plates (mostly convex) that are anchored with the concrete part and have the same shape as the beam section are used. As the basic plate for mechanical conversion, it is tightly anchored with the concrete part of the beam through the anchoring structure. The connection of the connecting plate (ie the connecting assembly) is integrated into a whole by bolting the cover plate.

The most basic form of anchoring is welding the end of the longitudinally stressed steel bar in the beam and the steel plate at the beam end; 2. If all the welded joints formed by the longitudinal steel bars provide If the anchoring capacity is insufficient, the anchoring steel bar is directly welded to the steel plate at the beam end, and the welding length and number of settings are determined by design; 3. When the beam end bears a large load and the above two methods cannot meet the bearing capacity requirements, it can be The anchoring reinforcing plate is welded with the steel plate at the beam end, and then the anchoring steel bar is welded with the two sides of the anchoring reinforcing plate and the steel plate at the beam end to improve the anchorage performance.

The outside of the steel plate at the beam end is the connection part between the beam end and the beam end.

The width of the upper horizontal connecting steel plate and the lower horizontal connecting steel plate is the same as the width of the beam section at this place or the surface decoration layer needs to be slightly narrower, as a whole plate welded on the upper and lower ends of the vertical connecting plate, and the middle horizontal connecting steel plate is welded in the vertical direction. Connecting the two sides of the steel plate, the outer width can be the same width as the outer side of the beam section, or the surface decoration layer needs to be slightly narrower. At the same time, the horizontal connecting steel plates are closely welded with the beam end steel plates. The upper horizontal connecting steel plate and the lower horizontal connecting steel plate are each one, and the number of the middle horizontal connecting steel plate is determined according to the design, and is arranged in parallel between the upper horizontal connecting steel plate and the lower horizontal connecting steel plate. The number, arrangement, size and shape of bolt holes on the horizontal connection steel plate are determined by design. The horizontal connecting steel plate is connected with high-strength bolts through the bolt cover plate, connecting the two beams into a whole. Of course, according to the design needs, the vertical bolt cover plate commonly used in steel structure construction can also be used to directly connect the vertical steel plate with high-strength bolts between the horizontal connection steel plates. Holes should be reserved for vertical connecting steel plates at the positions of floor connecting bolts. In the example of this patent, the shape of the reserved holes is semi-circular, and shapes such as elliptical holes can also be used according to factors such as processing, ease of construction and anchoring capacity.
