Abstract
The utility model relates to a standard joint of construction lift, comprising main chord pipes (1), horizontal beams (2) and a rack (3), wherein the horizontal beams (2) are fixed between the main chord pipes (1) and are slotted structure bodies formed by bending a plate material, welding surfaces of the two ends of each horizontal beam (2), in contact with the main chord pipes (1), are in shapes of circular arcs adaptive to the peripheries of the main chord pipes (1), and the rack (3) is vertically fixed in the middles of the horizontal beams (2). The standard joint disclosed by the utility model has the advantages of stable structure, operation reliability, large welding strength, easiness for forming, simple process, convenience for welding operation and the like; the appearance of a frame formed by bending a steel plate is attractive, the frame is painted without dead angles; the welding thermal deformation is smaller, and interchangeability between standard joints is good; and a driving rack is arranged on a central line of the side surface of the standard joint, and is more uniform under stress.
Description
Technical field
The utility model relates to vehicle for construction, is specifically related to the building hoist standard knot.
Background technology
In the elevator for building, as the standard knot that the track that climbs is used, what all adopt is that seamless tube is as main chord; Angle steel is welded into closed-in construction, and welding becomes standard knot, and there is certain defective in this design in actual fabrication; Because main chord is a pipe; And angle steel blanking aft end face is the plane, thereby makes the contact surface of these two parts become a contact, influence welding and moulding.If with shape in the arc-shaped under the angle steel end face, can make manufacture craft more complicated, also can reduce production efficiency to a great extent.
Summary of the invention
The utility model technical matters to be solved is: provide that a kind of technology is simple, Stability Analysis of Structures and reliable building hoist standard knot.
The technical solution of the utility model is: it comprises main chord tube, is fixed on horizontal beam and tooth bar between the main chord tube; Said horizontal beam is the bathtub construction body that is formed by the sheet material bending; The face of weld that the horizontal beam two ends contact with said main chord tube is the circular arc that adapts with the main chord tube periphery, and said tooth bar vertically is fixed on the horizontal beam position intermediate.
The technique effect of the utility model is: it has Stability Analysis of Structures, reliable, advantage such as weld strength is big, moulding is easy, technology is simple, welding operation is convenient.Adopt the outling of truss of steel plate bending elegant in appearance, japanning does not have the dead angle.The welding heat distortion is little, and interchangeability is good between the standard knot.Drive tooth bar and be placed in standard knot side position of center line, stressed more even.
Description of drawings
Fig. 1 is the constructional drawing of the utility model;
Fig. 2 is the constructional drawing of the utility model main chord tube and horizontal beam.
The specific embodiment
As illustrated in fig. 1 and 2; It comprises main chord tube 1, is fixed on horizontal beam 2 and tooth bar 3 between the main chord tube 1; Said horizontal beam 2 is the bathtub construction bodies that formed by the sheet material bending; The face of weld that horizontal beam 2 two ends contact with said main chord tube 1 is the circular arc that adapts with main chord tube 1 periphery, and said tooth bar 3 vertically is fixed on horizontal beam 2 position intermediate.
The utility model connecting frame is by steel plate bending punching, utilizes the advantage on the equipment, and blanking, bending, punching are all accomplished on one procedure, has not only improved work efficiency, and has been greatly improved in the quality of aspects such as moulding, welding.
Optimize on the mounting means, tooth bar is installed in standard knot side position of center line, the distribution of load that elevator is born is more reasonable, has increased the product durability, and the old-fashioned elevator of operating ratio is also steadily many.
Claims (1)
