Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the scaffold wall connecting member of this embodiment mainly includes an anchor ear 1, a cross beam 2, and three connecting rods 7 hinged to the cross beam 2.
The hoop 1 is made of flat steel and is used for semi-surrounding the column 6. The cross section of the flat steel is 50 x 5mm, and the length is 4.3 m. Screw rods 4 are welded and fixed at two ends of the flat steel. The diameter of the screw is phi 16mm, the length of the screw is not less than 320mm, and the length of the screw thread is not less than 80 mm. Double-sided welding is adopted between the screw and the flat steel, and the length of a welding line is not less than 160 mm.
Crossbeam 2 adopts 12 channel-section steels, and its physical properties: as =1536.2mm2，Ix=3.46*106mm4，Wx=5.77*104mm3(ii) a d =5.5mm, t =9.0 mm; the length of the channel steel is 3.4 m. A through hole for the screw rod 4 to pass through is arranged, and the screw rod 4 is tightened by the nut 5 so that the hoop 1 and the cross beam 2 are fixed on the column 6.
The back of the crossbeam is provided with a supporting block 8 for abutting against the cylinder 6, and the inner end of the supporting block is arc-shaped and is matched with the shape of the circular tube. The front of the beam 2 is welded with a plurality of pin joint connecting plates 9.
The connecting rod 7 is a scaffold tube with the diameter of 48 mm. The inner end of the connecting rod is spliced and welded with a rotating connecting plate 10. The pin connection plate 9 and the rotation connection plate 10 are rotatably connected through a pin or a bolt. The connecting rod 7 is fixed with the scaffold through a fastening connector.
The scaffold wall connecting piece is suitable for being manufactured and installed on site, and specifically comprises the following steps:
and (4) according to the CAD graph obtained by the calculation result, making model graphs of all the components, and explaining the installation flow of all the components in a picture intersection mode.
The 5mm connection steel plate of connecting rod 7 one end adoption steel pipe vertical grooving welding in the middle of, connection steel plate (rotation connecting plate 10) width is 80mm, and length is 120mm, wherein is 60mm with steel pipe incision connected segment length, and the embedding section adopts 5mm welding seam with the steel pipe, and full length welded connection targets in place. The connecting steel plate is provided with phi 14 holes and is connected with the profile steel side connecting pin ring by adopting phi 12 bolts.
