Detailed description of the invention
Embodiment 1:
A kind of packaged type scaffold bowl fastening type fastener, as Fig. 1, shown in Fig. 2 and Fig. 3, described scaffold bowl fastening type fastener is used for the connection of scaffold vertical tube 1 and transverse tube 2, comprise bowl button 3 and lower bowl button 4, described upper bowl button is docked by two cramps and is formed, wherein: described lower bowl button is also docked by two cramps and formed, on described, the shape and structure of lower bowl button is substantially close, as shown in Figures 2 and 3, on described, the cramp of lower bowl button comprises the first arc surface 5 and the second arc surface 6 of two different radiis up and down be mutually connected, the arc radius of the first arc surface is greater than the arc radius of the second arc surface, described first arc surface is the arc surface that outward opening tilts, as shown in Figure 1, described first arc surface connects the brace 2-1 of transverse tube for fastening, described second arc surface is used for encasing scaffold vertical tube 1, engaging lug 7 is respectively arranged with in the two side ends of the second arc surface, engaging lug is provided with bolt connecting hole 8, described scaffold bowl button also comprises a locating ring 9, described locating ring is relative by two and half ring plates, connected to form by bolt 10 locking, during use, locating ring is bolted on the scaffold vertical tube on bowl button, locating ring towards on bowl buckle end face face on be provided with positioning convex 9-1, described upper bowl button cramp upper surface is a spiral end face 3-1 with lead angle, bowl button in left rotation and right rotation, because spiral end face is subject to the spacing of positioning convex, described upper bowl button cramp is by the locking of the brace of transverse tube or unclamp.
Wherein: the angle of described lead angle is 10 degree to 30 degree.
In embodiment, upper bowl button can have two kinds of structures to the locking of transverse tube brace, the first: described two spiral end face cramps with lead angle docking formation continuous helical end face, the locating ring positioning convex that arrange corresponding to described continuous helical end face is one, the angle of this kind of its lead angle of structure can be smaller, such as 10 degree.It two is: as shown in Figure 1, described two spiral end face cramps with lead angle docking formation two symmetric helix end faces, the locating ring positioning convex that arrange corresponding to described two symmetric helix end faces is two, and the angle of this kind of its lead angle of structure can be larger, such as 20 degree.
In using: just can split out transverse tube to only unclamp upper bowl button, the spiral highest point height that end spiral end face buckled by described upper bowl is greater than height 1 to the 2mm being fastened transverse tube brace.
In embodiment, the surface that the second arc surface detained by described lower bowl is provided with stupefied tooth 6-1, described stupefied tooth prevents from described lower bowl to be buckled on scaffold vertical tube sliding after locking.Described stupefied tooth is the horizontal stupefied tooth of level triangle, can certainly be vertical or oblique stupefied tooth, and the stupefied tooth of level triangle is a kind of preferred plan.
In embodiment: in order to fixation, must ensure that the height that the first arc surface detained by described lower bowl is at least 30mm, the height that the second arc surface detained by described lower bowl is at least 50mm.
In using: the second arc surface of described upper bowl button only need first embrace scaffold vertical tube, rotational lock transverse tube brace is also needed in using, again upper bowl is detained two cramps afterwards and embrace the locking of scaffold vertical tube, the arc radius of its arc surface equals scaffold vertical tube radius or radius 1 to the 2mm slightly larger than scaffold vertical tube, and the circular arc that arc length is less than scaffold vertical tube 1/2nd circle is long; And lower bowl button will firmly be fixed on scaffold vertical tube, therefore, described in order to bolt fixation, the arc radius that the second arc surface detained by described lower bowl necessarily equals the radius of scaffold vertical tube, and, in order to make lower bowl button and the fixation of scaffold vertical tube, the circular arc that the arc length of described second arc surface is less than scaffold vertical tube 1/2nd round is long.
In embodiment: as a prioritization scheme, the arc length that the second arc surface detained by described lower bowl is that the circular arc of 3/4ths scaffold vertical tube 1/2nd circles is long.
Embodiment 2:
A method of operating for packaged type scaffold bowl fastening type fastener, comprise packaged type scaffold bowl fastening type fastener described in embodiment 1, the content in embodiment 1 also should be the present embodiment content; Its method of operating is: first cramp is connected to form lower bowl button, upper bowl button, two and half ring plate docking form locating ring, by locating ring, upper bowl button, lower bowl button along being inserted in sequence scaffold vertical tube, according to the position locking described lower bowl button of scaffold transverse tube on vertical tube, after connecting component of transverse pipe being inserted lower bowl button, upper bowl retaining ring is lived connecting component of transverse pipe, then by locating ring locking positioning, in rotation, bowl button locks upper bowl button after being compressed by connecting component of transverse pipe; If want to adjust the position of scaffold transverse tube on vertical tube, Zhi Xutiao Panasonic bowl button, upper bowl button and locating ring, lower bowl button is slided into desired location and repeat above-mentioned action and complete displacement.
Any position that the present embodiment scaffold bowl fastening type fastener can be implemented in scaffolding pole is connected with cross bar, overcomes the deficiency of existing scaffold bowl button, and convenient disassembly.
Be used for house top plate supporting system as bowl buckle scaffold, this support system is generally by the thick template of 20mm, 50x100mm secondary joist, and 100mmx100mm main joist, U-shaped holder, the vertical rod of bowl buckle frame, bowl buckle frame cross bar form.House floor height is generally 2800mm-3000mm, the height that general vertical rod is selected is that (physical length is 2200 to 2100 models, this model vertical rod is extensively present in scaffold leasing market) the vertical rod of bowl buckle frame, this model vertical rod has three bowl button nodes, go up most nodal point separation masthead 650mm, therefore this bowl of button bar is all standard component, and bowl button bit is put and cannot be changed.
According to Force Calculation and code requirement, after requiring vertical rod egress, length is not more than 500mm.Therefore, in construction or abandon a bowl buckle frame support system, or adopt the mode of common fastener to increase one deck girt in vertical rod more than the position of 500mm.
And use the present embodiment scaffold bowl button, can install in former 2100 model vertical rod optional positions, do not retrain by vertical rod stationary nodes, the vertical layer distance of girt can be adjusted arbitrarily.The advantage of the program is apart from slightly increasing, on basis that fastener node moves, meet code requirement (vertical rod egress is not more than 500mm) at horizon bar layer; And singly need not add one deck horizon bar (namely saving one deck horizon bar, fastener and corresponding human expenses of labour than original).The method does not change vertical rod structure, therefore neither affects the use of vertical rod at Other Engineering, does not need to drop into the special vertical rod of wholesale fund processing customization yet.
