Definitions

  • the invention relates to a mast anchor for fixing the mast of a construction hoist to a wall or the like. According to the preamble of claim 1.
  • construction lifts of various types are used, which basically consist of a mast to be erected in front of the building and a car or other load suspension device that can be moved along this mast. If the permissible free-standing mast height - usually up to 9 m - is exceeded, the mast must be anchored to the building so that the occurring driving forces and in particular wind forces are reliably diverted into the structure.
  • the invention is therefore based on the object of designing the mast anchor of the generic type in order to eliminate the disadvantages described in such a way that it allows a quick and secure anchorage of the mast with simultaneous insolation and allows a varied adaptation of the anchor to different conditions on site.
  • the mast anchor designed according to the invention allows the mast to be anchored quickly and securely to the structure. This not only ensures a high level of operational safety, but also helps to save time and costs at the construction site in question, which is a major advantage.
  • mast anchor according to the invention can dissipate very high forces into the structure, so that the anchoring distances between two anchors can be increased considerably, for example up to 16.5 m and more. This also results in a reduced installation effort due to the reduced number of fastening points required.
  • the mast anchor according to the invention which is designed in the form of an angled anchor with two legs, preferably in the form of an L-anchor with a longer and a shorter anchor leg, has the essential advantage that, on the one hand, it is basically like a rigid angular anchor - with which it results resulting advantageous consequences - is formed, on the other hand, however, because of the detachable, in particular adjustable connection provided between his legs, a diverse adaptation of the anchoring to different conditions on site enables.
  • the rigid connection of the mast anchor is retained, but if the wall of the building, as is often the case, deviates from the vertical and lies in a tilted and / or rotated plane, the anchoring can nevertheless be adapted accordingly without further ado.
  • the elevator mast always remains anchored in the vertical in the desired manner as well as held, while it is also secured against torsion.
  • the mast anchor In order to achieve this fixability of the mast anchor, it is preferably designed such that the connection point of its two legs can be adjusted at least along one leg. This can be done continuously or in stages. In the latter case, it is advantageous if that leg of the mast anchor, which serves as an anchor bracket and is provided for fixing to the wall, has at least part of its length of a row of holes, by means of which the anchor bracket via a screw connection at any point on the anchor bracket is definable.
  • This row of holes is preferably designed as a pair of rows of holes and can also be provided on the opposite side of the anchor bracket.
  • the other leg of the mast anchor which serves as an arm bracket and is provided for fixing to the mast, can be optionally fixed on one of the two sides of the anchor carrier. It is within the scope of the invention that the armature arm can also act with its other end either on either side of the mast, either on-site or away from the site.
  • the mast can still be corrected to a certain extent via an adjusting element after the mast anchor has been attached. This can be done, for example, by means of a spindle, by means of which the armature arm is fixed to the mast, and / or by means of corresponding tightening of the screw connection which engages in a desired hole pattern of the armature carrier and fixes the armature arm thereon.
  • the mast anchor With the mast anchor according to the invention, it is possible for the first time to correct deviations of the mast from the plumb to a certain extent without further aids when the next anchor is set, if the longer anchor leg is first mounted on the wall according to the deviation. It does not matter whether the wall is at an angle or at right angles to the construction elevator or whether it jumps forward or back.
  • the free mast tip which is slightly bent in the direction of the load handler, can be brought back into position by means of the screw connections over the shorter leg and the longer leg that was precisely mounted beforehand. Likewise, the free mast tip can be adjusted in the event of a deviation towards or away from the building via a suitable selection of the connecting holes and by means of the spindle provided at the free end of the shorter leg.
  • the movable linkage which is provided between the shorter anchor leg and the mast belt facing away from the load suspension device, enables an always adaptable connection to the torsion protection of the mast even when the mast anchor is not used at right angles to the construction. All of this simplifies, facilitates and accelerates mast assembly considerably.
  • the anchor by means of at least one fixed frame which can be inserted between the anchor support and the wall.
  • Such an increase in the length of the mast anchor can be carried out in the manner indicated, without the anchor losing its original flexibility or rigidity.
  • a building lift mast 2 is erected in front of a building 1, on or in which construction work is to be carried out, which is assembled in a conventional manner from individual mast elements 3 and along which a car 4 or another load suspension device can be moved.
  • the construction mast 2 is anchored to the outer wall 6 of the building 1 by means of various mast anchors 5, which are provided at desired or required intervals.
  • the arrangement is such that the mast anchors 5 engage with their respective on-site end at such a point on the building wall 6 that lie on concrete ceilings 7 or the like.
  • the mast anchor 5 is in the form of a rigid angular anchor - in the illustrated embodiment in the form of an L-shaped anchor - which has two legs 8, 9.
  • the longer leg 8 serves as an anchor bracket, which is to be fixed on the wall 6 of the building 1
  • the shorter leg 9 serves as an anchor bracket, which acts on the mast 2.
  • the armature legs 8, 9 arranged at right angles to one another are rigid, but releasably connected to one another, namely by means of a screw connection 10, not shown in detail.
  • the connection point of the two legs 8, 9 can be adjusted in steps along the longer leg 8.
  • the anchor carrier 8 has a row of holes 11 on both sides over part of its length, which in each case receives the screw connection 10 between the two legs 8, 9 at any desired location. This makes it possible to change the effective length of the anchor bracket 8 in a fast but at the same time safe manner and thereby adapt the overall dimension of the mast anchor 5 to the respective conditions on site.
  • the armature arm 9 can optionally be fixed on either side of the armature support 8, this fixation taking place in the illustrated embodiment according to FIG. 2 on the left side of the armature support 8, viewed in plan view, in such a way that the armature arm 8 is provided by the customer on Mast 2 attacks.
  • the relevant mast element 3 of the building lift mast 2 is provided with an internal holding tube 12, on which the armature arm 9 engages, for example by means of a quick coupling 13, in particular in the form of a pipe clamp or the like.
  • a screw spindle 14 is provided, which passes through a nut 15 fastened to the free end of the arm bracket 9 and is fixed with its free end in the manner described to the inner holding tube 12 of the mast 2.
  • the mast 2 can still be continuously corrected to a certain extent after the mast anchor 5 has been fastened, specifically by adjusting the screw spindle 14 serving as an adjusting element until the building mast 2 is exactly vertical. Further adjustment options are of course given by appropriate selection of the hole pairs of the hole pair row 11.
  • FIG. 2 there is a further connection between the anchor bracket 9 and mast 2 given that the mast belt facing away from the load-carrying means is connected to the armature boom 9 by means of a further quick coupling 16.
  • a holding tube 20 is provided, which is connected to the quick coupling 16 at one point of its length and engages at one end on the armature cantilever 9.
  • the anchor carrier 8 is connected to the wall 6 of the building 1 via an anchor plate 17 which is fastened in the manner already mentioned at the level of a concrete ceiling 7 of the building 1, for example by means of through screws and counter plate.
  • the mast anchor 5 is also provided with a support 18 in the form of a suitable strut tube or profile. This extends on the mast side between the anchor bracket 8 and the wall 6 and, as indicated by dashed lines in FIG. 2, can also be arranged on the side of the mast anchor 5 facing away from the mast 2.
  • the modified example of use of the mast anchor 5 according to FIG. 3 differs from the previously described embodiment in that the anchor bracket 9 is rotated by 180 ° in its longitudinal axis and is fastened to the right side of the anchor carrier 8, as seen in plan view, and not on site, but attacks from the side facing away from the mast 2, ie So grips the mast 2.
  • the support 18 is always arranged on the side of the anchor carrier 8 facing away from the mast 2.
  • the entire mast anchor 5 is increased in length in that it is extended by a fixed frame 19 which is inserted or fastened between anchor bracket 8 and wall 6.
  • This type of arrangement is always of particular advantage if, for local reasons, For example, unloading above a glass facade, the construction hoist must be installed in such a way that the drive of the load handling device 4 is located between the mast 2 and the structure 1.
