Abstract
The utility model discloses a kind of dish buckle type scaffold cat ladder hook, comprise hanger bulk and be connected to the snap close in hanger bulk, on the downside of the outer end of hanger bulk, have mounting curved surface.Mounting curved surface comprises planarea and the symmetrical arc surface being positioned at planarea both sides, makes hook have former and later two mounting confined planes.The difference of the center to center distance between the both sides vertical rod of different size scaffold is regulated by planarea, a kind of cat ladder of specification is made to be applicable to the dish buckle type scaffold of obstructed specification, thus make the cross bar length of different size disc buckle type scaffold identical, the object that the cat ladder of model dish buckle type scaffold not of the same race and cross bar can be general can be realized, reduce the input cost of scaffold.
Description
Technical field
The utility model relates to a kind of hook, is specifically related to a kind of dish buckle type scaffold cat ladder hook.
Background technology
Scaffold steel cat ladder widely uses along with dish buckle type scaffold, is also applied to the projects such as decoration of exterior wall, Bridge High-pier construction operation, industrial chimney.And in the middle of building operations, the operation path, escape way, passageway for fire apparatus etc. of constructor also play vital effect in construction operation process.The specification of dish buckle type scaffold has 48 types and two kinds, 60 types substantially, two profiles dialer buckle type scaffold cross bar length difference 12mm, for reducing cross bar specification, two kinds of system product cross bars are adopted same length specification, between the cross bar of then general latter two system, center to center distance difference 12mm, also just makes the cat ladder length of matching used scaffold with it also differ 12mm, makes so easily to occur the situation that materials are obscured when making, reduce operating efficiency, increase cost of manufacture.
Utility model content
The purpose of this utility model is to provide a kind of hook of adjustable cat ladder mounting length, makes the cat ladder of model dish buckle type scaffold not of the same race and cross bar can be general, lowers cost of manufacture.
The utility model discloses a kind of dish buckle type scaffold cat ladder hook, comprise hanger bulk and be connected to the snap close in hanger bulk, on the downside of the outer end of hanger bulk, have mounting curved surface.Mounting curved surface comprises planarea and the symmetrical arc surface being positioned at planarea both sides, is regulated the difference of the center to center distance between the both sides vertical rod of different size scaffold by planarea.
The arc surface bend radius of described mount surface is 24mm, planarea length is 6mm, to make the cat ladder of the general a kind of specification of the dish buckle type scaffold of 48 types and 60 types energy.
Described snap close offers arcuate socket along its length, by being riveted on the inner of mount surface in described hanger bulk through the flat head rivet of arcuate socket.
The rear end of described hanger bulk offers the bolt hole for being connected with cat ladder frame.
Mount surface between cat ladder hook and cross bar is designed to the combination of arc surface and planarea by the utility model, hook is made to have former and later two mounting confined planes, the range difference between the cross bar of different model scaffold both sides is regulated by planarea, a kind of cat ladder of specification is made to be applicable to the dish buckle type scaffold of obstructed specification, thus make the cross bar length of different size disc buckle type scaffold identical, the object that the cat ladder of model dish buckle type scaffold not of the same race and cross bar can be general can be realized.
Compare with prior art, the bilateral symmetry that the mount surface of hanger bulk is improved to middle planarea by one section of arc surface is connected arc surface by the utility model, the difference of the center to center distance between different shaped dialer buckle type scaffold offside cross bar is regulated by planarea, make the cat ladder of different shaped dialer buckle type scaffold and cross bar can be general, reduce the input cost of scaffold.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
As shown in Figure 1, present embodiment discloses a kind of dish buckle type scaffold cat ladder hook, comprise hanger bulk 1 and snap close 2, the mounting curved surface surrounded by planarea 11 and the symmetrical arc surface 12 being positioned at planarea 11 both sides is had on the downside of the outer end of hanger bulk 1, snap close 2 offers arcuate socket 21 along its length, by being riveted on the inner of mount surface in hanger bulk 1 through the flat head rivet of arcuate socket 21.The rear end of hanger bulk 1 offers bolt hole 13, is connected with cat ladder frame by bolt.
For 48 types and 60 type dish buckle type scaffolds, when making the cross bar length of two profiles number equal, two cross bar center to center distance difference 12mm of offside.Because the two ends of cat ladder are all connected with hook, so the planarea length of hanger bulk mount surface to be defined as the half 6mm of two model scaffold offside cross bar center to center distance, the arc surface bend radius of planarea both sides is consistent with the radius of cross bar 24mm is namely by linking up with the difference of the center to center distance regulated between two profiles scaffold offside cross bar: when cat ladder is used in 48 type buckle type scaffold, the inner arc face of hook mount surface is the confined planes with cross bar, when cat ladder is used in 60 type buckle type scaffold, the outer arc face of hook mount surface is the confined planes with cross bar.Namely hook between cross bar by different confined planes locate mount to regulate cat ladder both sides link up with between center to center distance, this adjustment is realized by the planarea between arc surface.
