The basic forms of the fabricated scaffold are divided into a clamp type and a horse board welding type. The assembled scaffold has the following advantages: the scaffold is not required to be erected layer by layer from bottom to top, and is only erected at a required place, so that a large amount of material cost and labor cost can be saved, and the erecting efficiency of the scaffold is improved; the subsection presetting can be realized, and the scaffold is preset in the subsection stage, so that the time for setting up the scaffold in the dock can be reduced, and the shipbuilding period is shortened; the occupation of the operation space can be reduced to the maximum extent, and a wider and comfortable working environment is provided for the construction of field workers; the coating damage can be reduced to the maximum extent, the coating protection is facilitated, and the coating material and labor cost are reduced.
The assembled scaffold comprises a railing upright post, a supporting cross rod, a railing cross rod, a clamping head and the like. The railing upright post, the supporting cross rod and the railing cross rod are all round tubes, and the bottom, the middle and the upper part of the railing upright post are respectively welded with a U-shaped clamp; the middle chuck is used for clamping the support cross rod and is fixed through a chuck bolt; the upper clamp is used for clamping the railing cross rod and is fixed through a clamp bolt; the bottom chuck is used for clamping the hull plate and is fixed through a chuck bolt; when the assembled scaffold is erected, the bottom clamp is clamped at the outer end of the ship body plate, and then the clamp bolt is screwed down to fix the scaffold on the ship body plate. Because the outer wall of railing post is the rear end face welding of direct and bottom chuck, two following problems easily appear in the long-term use of this kind of assembled scaffold: the lower end of the railing post is bent and deformed; the weld between the railing post and the bottom chuck is prone to cracking. Above-mentioned two problems not only influence the life of scaffold frame, still have very big potential safety hazard.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's defect and provide a connection structure of assembled scaffold railing stand and bottom chuck, it can improve the joint strength of railing stand and bottom chuck to the life and the security of scaffold have been improved.
The purpose of the utility model is realized like this: a connecting structure of an assembled scaffold railing upright post and a bottom chuck comprises a circular tube-shaped railing upright post, a first rib plate and a second rib plate of the bottom chuck; wherein,
the bottom chuck is a U-shaped clamping plate with a certain width and is arranged horizontally in a mode that the opening faces away from the railing post, and the middle part of the back face of the bottom chuck is welded on the outer wall surface of the bottom of the railing post along the axial direction of the railing post;
the first rib plate is a right-angle triangular plate and is vertically arranged, the short right-angle edge of the first rib plate is longitudinally welded in the middle of the top surface of the bottom chuck, and the long right-angle edge of the first rib plate is welded on the outer wall surface of the railing stand column along the axial direction of the railing stand column;
the second rib plates are in an isosceles trapezoid shape and are horizontally arranged, the top surfaces of the second rib plates are welded to the bottom surface of the bottom chuck, and the upper bottom edges of the second rib plates are welded to the outer wall surface of the bottom of the railing stand column.
In the connection structure of the assembled scaffold railing column and the bottom chuck, the first rib plate is an L-shaped plate, and the bending part of the L-shaped plate is rounded.
According to the connecting structure of the assembled scaffold railing stand column and the bottom chuck, the height of the second rib plate is at least one half of the depth of the bottom chuck, the length of the lower bottom edge of the second rib plate is matched with the width of the bottom chuck, and the upper bottom edge of the second rib plate is a concave arc edge matched with the outer wall surface of the railing stand column.
The utility model discloses a connection structure of assembled scaffold railing stand and bottom chuck has following characteristics: because first gusset and second gusset have been increased between bottom chuck and railing stand for the bottom of railing stand is difficult to produce bending deformation, and the welding seam between railing stand and the bottom chuck is difficult to be torn by the atress and destroys, has improved the joint strength of railing stand and bottom chuck, thereby has improved the life and the security of scaffold frame.
