The embodiment discloses an externally-hung prefabricated wall panel connecting node convenient for installation position adjustment, as shown in fig. 1 to 8, comprising a prefabricated wall panel 1, a PEC beam 4, an embedded part 2, a connecting hanging seat 3 and a pi-shaped member 5. The PEC beam 4 is of a concrete-coated H-shaped steel structure, an embedded part 2 is embedded in the connection point of the prefabricated wall board 1, and part of the embedded part 2 is exposed out of the outer surface of the prefabricated wall board 1; the connecting hanging seat 3 adopts an L-shaped steel structure, namely comprises a vertical wing plate 31 and a transverse wing plate 32, and the vertical wing plate 31 and the transverse wing plate 32 are connected by a stiffening rib 33; the vertical wing plate 31 is welded with the exposed end of the embedded part 2, and the transverse wing plate 32 is provided with a first through kidney-shaped hole 34. The pi-shaped member 5 comprises a top plate 51 and two legs 52 connected with the top plate 51 at the lower part of the top plate 51, the bottoms of the two legs 52 are welded on the top of the upper flange of the PEC beam 4, a second waist-shaped hole 53 penetrating through the top plate 51 of the pi-shaped member 5 is formed, the length direction of the first waist-shaped hole 34 is perpendicular to the length direction of the second waist-shaped hole 53, so that the positions of the two different directions can be adjusted, and the transverse wing plate 32 is connected with the top plate 51 of the pi-shaped member 5 by a bolt 6.
The prefabricated wall panel 1 usually adopts many light wall panels, and the wall panels mostly adopt regular structures, but for pursuing visual aesthetics and design for the outer wall in many buildings, the external wall panel also adopts irregular special-shaped structures, and in this embodiment, the irregular special-shaped structure wall panel is taken as an example for display, and the advantages of the connection node disclosed in this embodiment to the special-shaped wall panel are explained. Of course, the connection node of the present embodiment is also applicable to regular prefabricated wall panels.
When the prefabricated wall panel 1 has a structure with a cross section as shown in fig. 1, which is thick at the top and narrow at the bottom, the outer vertical surface (i.e., the outer wall surface) of the prefabricated wall panel 1 should be a flat surface, and the inner wall surface should be a non-flat surface, since the prefabricated wall panel is mostly formed as an outer wall panel by splicing. The outer wall plate and the beam are usually connected with the upper flange of the beam in a hanging mode, so that the thickness of the wall plate at the hanging point is larger than that of the lower portion of the hanging point, and the outward inclination caused by unstable gravity center due to the fact that the upper portion is light and the lower portion is heavy is avoided. Therefore, the embedded part 2 should be arranged inside one end with a thicker thickness, and the lower part of the inner wall surface of the exposed end of the embedded part 2 is concaved inwards to reduce the thickness of the lower part. In consideration of the stability of the stress of the connection node, the embedded part 2 in this embodiment is structured as shown in fig. 2 and 3, the embedded part 2 includes a first steel plate 21 and a second steel plate 22 which are arranged in parallel, the first steel plate 21 and the second steel plate 22 are connected into a whole through a connection rod 23 at a certain distance, and the outer surface of the first steel plate 21 is exposed out of the surface of the prefabricated wall panel 1. In order to increase the connection area between the embedded part 2 and the connection hanging seat 3, the first steel plate 21 and the second steel plate 22 are designed to be rectangular, a square is used as a good, the four corners of the square steel plate are respectively provided with a connecting rod 23, and the embedded part with the structure is strong in stress and not prone to deformation.
The structure of the connection hanging seat 3 for connecting the prefabricated external wall 1 and the PEC beam 4 is also very critical, and the connection hanging seat needs to have strong stress and tensile resistance, otherwise, the outward inclination of the wallboard is easily caused. In this embodiment, the connecting hanging seat 3 is additionally provided with a reinforcing rib 33, as shown in fig. 4 and 5, the reinforcing rib 33 is made of a steel plate, the reinforcing rib 33 is respectively perpendicular to the transverse wing plate 32 and the vertical wing plate 31, the transverse wing plate 32 and the vertical wing plate 31 can be bent to form an L-shaped structure, one side edge of the reinforcing rib 33 is welded to the vertical wing plate 31, and the other side edge is welded to the transverse wing plate 32, and it is suggested that two reinforcing ribs 33 are provided, and the two reinforcing ribs 33 are spaced apart and respectively provided at two sides near the edges, so that a better tensile effect is achieved, and the first kidney-shaped hole 34 is provided between the two reinforcing ribs 33. Considering that the temporary fixation of the prefabricated wall panel 1 needs to provide convenience for welding operation, the embedded part 2 and the vertical wing plate 31 can be pre-fixed through the bolt fastener, namely, a threaded hole is formed in the exposed end (the first steel plate 21) of the embedded part 2, a corresponding hole is formed in the vertical wing plate 31, the two parts are connected through a bolt after being adjusted in position, and then the edge seam of the edge is welded.
Two legs 52 at the lower part of the top plate 51 of the pi-shaped member 5 are arranged in parallel and at intervals, two legs 52 are made of steel plates with the width equal to that of the top plate 51, the tops of the legs 52 are welded on the bottom surface of the top plate 51, the bottoms of the legs 52 are welded on the top surface of the upper flange of the PEC beam 4, and a second kidney-shaped hole 53 is arranged between the two legs 52. The steel plate surface used by the supporting leg 52 and the steel plate surface used by the stiffening rib 33 are arranged in the direction perpendicular to each other, so that better stress effect is achieved. By taking the length direction of the upper flange of the H-shaped steel inside the PEC beam 4 as a reference direction, when the prefabricated wall panel 1 is of a structure with a thick upper part and a narrow lower part as shown in figure 1, the length direction of the first waist-shaped hole 34 is perpendicular to the length direction of the upper flange of the H-shaped steel, and the length direction of the second waist-shaped hole 53 is consistent with the length direction of the upper flange of the H-shaped steel, so that the distance between the prefabricated wall panel 1 and the web side of the PEC beam 4 can be adjusted and corrected conveniently according to an actual assembly position, and the position of the prefabricated wall panel 1 along the length direction of the upper flange of the PEC beam 4 can be adjusted and corrected conveniently.
