- the wedge-end surface 500 of the lower wedge end portion 501 is rounded with a radius 504, the RESIZE ⁇ SSER than half of the lower wedge width 498, or in wel ⁇ cher the wedge 362 497 of the rear from the rear vertical surface
- the first wedge front edge 462 and the front, parallel thereto vertical surface 505 of the front and second wedge front edge 463 is limited.
- the wedge end surface 500 rises slightly rearward 52 beyond said rearward vertical surface 497 such that there is an increase 506 formed.
- This is provided in order to ensure that the wedge 362, when inserted through the upper wedge opening 80 and captively secured to the terminal head 361 by means of the captive 203, is secured in an upward pull-up condition in the course of a back 52 and 115 down to the contact of the wedge 362 with its rear or first wedge front edge 462 in the region of the upper wedge end 481 on the outer surface 155th a fixed to the connection part 364 of the connection head 361 verbun ⁇ which rod element, preferably a round tube 78, pro- can be handled without a problem.
- the rounded wedge End surface 500 of the lower wedge-end part 501 merges tangentially into the front contact surface 466 of the front and second wedge front edge 463, respectively, in a partial region assigned to the front, second wedge-front edge 463.
- the wedge 362 has a rearwardly facing outward 52 and a first wedge leading edge 462, respectively, which are a substantially planar, obliquely outwardly 52 and 115 at an inclination angle 470 to the vertical axis 148 along a Has oblique axis 469 extending contact surface 468.
- the contact surface 468 of the first wedge-front edge 462 is located when the wedge 362 is in the locking position 388 and the terminal head 361 is braced by means of the wedge 362 with the vertical framework member 41, or when the wedge 362 in the locked position 388, only locally in the region of the upper recess edge 580 of an opening 55; 55.1 of the projection or the perforated disc 44 on the inward and forward facing 79 vertical wedge support surface 229 of the outer projection portion 97 at.
- the wedge 62 furthermore has a front edge or second wedge end edge 463 which points in the transverse direction 118 forwards or inwards 79 and which has a substantially planar vertical contact surface 366 extending parallel to the vertical axis 148 or rectilinearly.
- This Kon ⁇ clock area 366 corresponds both with the upper wedge supporting surface 525 of the upper head portion 374 and with the lower wedge supporting surface 531 of the lower head portion 375 such that the vertical contact surface 366 of the wedge 362 and the vertical wedge Support surfaces 525, 531 of the connection head 361 parallel to each other and flat against each other the adjacent, relative to each other along or in the direction of the vertical axis 148, are displaceable.
- the wedge is 362 of the terminal head 361, when the connection head 361 is intended placed on a pre ⁇ jump or a perforated disc 44 of a vertical Ge ⁇ rüstelements or scaffold stem 41 such that the wedge through the top in the header 374 and formed in the lower head portion 375 passage 384, crossing the slot 67 through an opening 55; 55.1 of the projection or the perforated disc 44 is inserted therethrough and is accordingly in a locking position 388, with its front, in the direction of the vertical frame element or scaffold post 41 facing, straight leading edge 463 or with their contact surface 466 to the kor ⁇ responding wedge support surfaces 525, 531 of the straight inner edges of the connection head 361, while the wedge 362 at the same time with its rear, away from the vertical framework element or the scaffold stalk 41 away, obliquely trailing edge 362 and their contact surface 468 point or horizontally-line-shaped at the vertically or vertically extending inner edge or its wedge support surface 229 ei ⁇ ner opening 55; 55.1, 5
- connection head 361 differs from connection head 61 in that it is made of malleable or chilled cast iron, the risk of damage or even a breakage of Zentrierlappen 550.1, 550.2, 550.3 when handling the same or in a Dropping the same, for example, on a conveyor belt, minimized.
- the Zentrierlappen 550.1, 550.2, 550.3 in the second embodiment shown now no longer designed the same and no longer offset in the same circumferential angles to each other.
- the two Zen ⁇ trier lobes 550.1 and 550.3 are arranged offset in a circumferential angle 551.1 of about 180 degrees to each other.
- the ⁇ difference to the in circumferential direction viewed between these two centering tabs 550.1 and 550.3 are arranged further to the adjacent centering tabs Zentrierläppen 550.2 550.1, 550.3 arranged in each case offset at an equal circumferential angle 551.2 of only about 90 degrees (Figure 46).
- the said further centering tab 550.2 is assigned to the lower head part 375 of the connection head 361.
- the tilt angle 436 of the zinc discharge opening 447 in the terminal head 361 according to the second exporting ⁇ approximately, for example with respect to the inclination angle 136 of the Zinkaus ⁇ overflow aperture 447 is ver enlarges ⁇ at the connection head 361 according to the first embodiment of about 57 degrees to about 75 degrees.
- the cross-sectional area of the wedge support body 385 formed or shown in the vertical section according to FIG. 18 is correspondingly increased. This in turn resulting casting technology advantages and also an IMP EXP ⁇ including higher load capacity of the connection head 361 against ⁇ on the connection head 61.
- connection head 61 according to the first exporting ⁇ approximately, for example, is also in the terminal head 361 according to the second embodiment, the slot 67 in the region of its Schlitzcampuses 103.1, 103.2 with an after ⁇ half of in the insertion area 93; 93.1 formed horizontal horizontal upper slot surfaces 95.1 of the slot 67 extending paragraph 400 of the upper head portion 374 which is limited down 115 with a horizontal upper paragraph slot surface 107 of the slot 67 and the paragraph 400.
- the shoulder 400 of the connection head 361 is delimited to the front 79, ie towards the insertion region 93 of the slot 67, with an oblique surface 113 of a front insertion bevel 282. This extends obliquely downward 115 and rear or outside 52 to the slot bottom 103.1, 103.2 out and transitions outwardly or rearwardly 52 into the horizontal heel slot surface 107 of the heel 400.
- the inclined surface 113 includes with the horizontal 274 and the paragraph slot surface 107 a, preferably about 20 degrees amount, inclination angle 283 a.
- the wedge support surfaces 108 of the wedge support body 385 located in the region adjacent to the front release edge 128 are in a small vertical one Distance 429 above the paragraph slot surface 107 is arranged.
- the distance 429 is smaller than half the slot height 98 or width in the insertion region 93 of the slot 67.
- the distance 429 is slightly larger than the distance 129, so that in this region of the shoulder 400 or of the wedge Support body 385 a greater Materialanphaseu ⁇ tion or a greater material thickness is reached. As a result, correspondingly improved static characteristics of this connection head 361 can be achieved.
- the paragraph 400 is additionally provided with lateral insertion bevels 585.1, 585.2.
