Definitions

  • ABSTRACT An elevator system in which a temporary hoistway is formed in an open air shaft of a building under con struction.
  • the hoistway members which in turn support the guide rails, are connected to the building members in a manner that, upon forces being exerted on the guide rails, these forces are distributed to several levels of thebuilding.
  • the buffer assembly for protection against downward overtravel is connected to-the rails and is movable upward as construction progresses. A method of using this arrangement to provide passenger elevator service into unaligned steelwork of a building under construction is also described.
  • the guide rails might be supported in a temporary manner from unaligned steel whereby the final rail alignment might possibly be postponed until all the building steel is finally aligned. This, however,
  • Another object is to provide an elevator which is capable of carrying workmen up into the unaligned steelwork portion of a building.
  • a feature of the present invention is that the lower terminal of the elevator can be shifted upwards as the building progresses.
  • Another feature of the invention is that the forementioned temporary hoistway arrangement lends itself to the utilization of preassembled units. This reduces installation labor resulting in a consequent saving in time and money over the installation of nonassembled units in a permanent hoistway.
  • an elevator is provided which is suitable for use in a building under construction by erecting within a vertical air shaft of the building a temporary hoistway that has its lower terminal adjustably determined by a movable buffer assembly.
  • the air shaft at a location that differs from the permanent elevator hoistway, is defined by horizontal structural members which form the floor levels of the building.
  • the temporary hoistway therein is formed by a plurality of pairs of vertically flexible members, each pair of which for convenience may be included within a frame, secured to the horizontal structural members in a predetermined manner about a vertical axis and by elevator car guide rails that are fixed to and interconnect the pairs of vertically flexible members or buffer frames.
  • a buffer assembly is releasably engaged to the rails below the lower terminal and supports the buffer thereon.
  • the points at which the rails are attached are located on the vertically flexible members so that forces exerted on the rails are transmitted to the horizontal structural members on several floor levels of the buildmg.
  • FIG. 1 is a pictorial view showing the application of the invention to an elevator system useful during the construction of a building;
  • FIG. 2 is an isometric view showing a movable elevator car buffer assembly and the underside of an elevator car;
  • FIG. 3 is a fragmentary view showing details of the movable buffer assembly of FIG. 2;
  • FIG. 4 is an isometric view showing a frame member used in assembling the temporary hoistway of the system of FIG. 1;
  • FIG. 5 is a fragmentary view showing details of a unit used in securing the frame member of FIG. 4 to a building structure
  • FIG. 6 is a fragmentary view showing details of another unit used in securing the frame member of FIG. 4 to a building structure.
  • an elevator system having a plurality of like rectangular frames 21 (FIG. 4), each mounted atop and secured to horizontal structural first members 22 of a building framework. These first members together form a suitable vertical air shaft extending through several floor levels of a building.
  • Each of frames 21 may be disposed in the same relative position about the longitudinal axis 23 of the air shaft.
  • Frames 21 are interconnected by being connected to elevator car guide rails 24 in any satisfactory manner such as by typical rail clips.
  • Guide rails 24 comprise a plurality of rail sections suitably joined together. These guide rails 24 guide elevator car 25 which is equipped with overspeed safety mechanism (not shown) in the normal fashion. Frames 21 and a pair of vertically extending guide rails 24 together form a temporary'hoistway for the elevator car. The upper and lower terminals within this temporary hoistway are defined by the positions of movable car buffer assembly 31 and portable machine room 32.
  • Elevator car buffer assembly 31 (FIG. 2) is connected across guide rails 24.
  • a second typical elevator car safety mechanism is modified to mount the buffer.
  • This arrangement includes buffer frame 35 and a pair of rail engagement assemblies 36.
  • Mounted atop the buffer frame 35 is at least one buffer 34 which in this particular embodiment is illustrated as a pair of spring buffers 34 although oil buffers are also suitable. While any sufficiently strong crosspiece connected between guide rail 24 might be satisfactory for mounting the buffer, the modified safety mechanism disclosed herein is particularly convenient.
  • Counterweight 45 is guided by counterweight guide rails 46 (FIG. 1) which are suitably attached to hoistway frames 21.
  • counterweight 45 is roped 2:1 (as is car 25) by means of detachable sheave assembly 49 which is also guided by rails 46.
  • a counterweight buffer assembly (not shown) is provided for the counterweight 45 but is not described in detail as it is similar to elevator car buffer assembly 31, except for being adapted to the dimensions of rails 46.
  • Each spring buffer 34 (FIG. 2) of elevator car buffer assembly 31 comprises buffer spring 60 and spring mount 61. These are supported atop upper channel beam 62, the uppermost element of a substantially rectangular buffer frame 35. Buffer frame 35 also includes lower frame beam 63. At each corner of the buffer frame 35 and extending outwardly therefrom is a notched guide shoe 64 for cooperation with its respective rail 24.
  • each side of upper channel beam 62 is a pair of rail engagement assemblies 36 for releasably attaching buffer assembly 31 to guide rails 24.
  • Each of these assemblies comprises spring-loaded lever arm 65, linkage rod 66, roller 67 (FIG. 3), and safety block 68 (FIG. 3).
  • Vertical supports 69 of buffer frame 35 are fastened between upper channel beam 62 and lower frame beam 63.
  • Cross brace 70 is connected between supports 69.
  • Each lever arm 65 is pivotally connected at a point intermediate its two ends to a different one of vertical supports 69.
  • One end of each lever arm is connected to spring biasing unit 71, each of which is attached to cross brace 70.
  • the other end of each lever arm 65 is connected through linkage rod 66 to roller 67 retained within roller-retaining cavity 72 of safety block 68.
  • roller 67 is urged into engagement with its associated rail 24 by being forced up the wedge-shaped channel formed by the inclined surface 73 of safety block 68 and the surface of guiding web 74 of guide rail 24.
  • This wedging of the roller between safety block and rail at a predetermined vertical location along the guide rail 24 is achieved by the force of spring biasing unit 71 being applied to the roller 67 through arm 65 and rod 66.
  • Engagement releasing brackets 75 are attached to the underside of upper channel beam 62, a different one for cooperating with each lever arm 65.
  • Each lever arm can be detachably coupled to its respective bracket whereby the associ ated rail engagement assembly 36 is retained in a released position with its roller 67 out of engagement with the associated rail 24 so that buffer assembly 31 may be readily moved to changeits vertical location.
  • upper channel beam 62 is also adapted to engage eyebolts 76 which may be attached to the underside of car 25 by means of brackets 77 and pins 78.
  • An illustrative one of frames 21, shown in detail in FIG. 4, includes a pair of horizontally disposed I-beams 80. These I-beams rest on and are suitably fastened to short I-beam sections 79 which are mounted on horizontal structural first members 22. Suitably, I-beams 80 and horizontal structural members 22 are at right angles to each other. I-beam sections 79 may be secured to the building by any of several suitable attaching means which would satisfactorily join them to horizontal structural members 22.
  • Each frame 21 includes a pair of horizontally disposed vertically flexible second members 81, which second members are disposed in substantially the same relative position to the longitudinal axis 23 of the air shaft.
  • vertically flexible second members 81 comprise channel beams on opposite sides of the frame 21 having longitudinally extending upwardly disposed plates 82 welded thereto.
  • Each of vertically flexible second members 81 is mounted atop a respective l-beam 80 and is in substantial vertical alignment with corresponding ones of other frames 21 in that the longitudinal axes of corresponding second members 81 are parallel to and coplanar with each other.
  • the corresponding substantially vertically aligned second members 81 are thereby formed into two sets, of which each set is in a separate plane, which in turn has longitudinal axis 23 parallel to it.
  • Each vertically flexible second member 81 is separated from its respective I-beam 80 a predetermined amount by a pair of securing means of the type illustrated in FIG. 5.
  • each side'member 81 provides it with its vertically flexible characteristic and determines the amount the member will deflect under a given amount of force applied thereto.
  • Each elevator car guide rail 24 (FIGS. 1 and 2) is connected in any suitable manner to members 81 at approximately the midpoint of their active spans.
  • Frame members 83 and 84 joining the members 81 at the front and rear thereof, which may take any suitable shape, are fastened to the ends of each side member 81 by endplates 85 which are welded to their respective front and rear members.
  • Angles 86 and braces 87 are attached to the underside of rear frame member 84 in predetermined locations to form rail mounting brackets enabling counterweight rails 46 (FIGS. 1 and 2) to be supported thereon and to interconnect rear frame members 84.
  • the securing means shown in FIG. 5 secures members 81 to l-beams 80 at each end of the active span of each member 81.
  • L-shaped strap 91 is bolted to side member 81 through plate 82.
  • Spacer 92 between the bottom of member 81 and the top of I-beam' 80 is bolted to the leg of strap 91 and clamped to the flange of beam 80 by clamping plate 93.
  • the rear ends of members 81 are secured to beams 80 through the use of flat straps 94 (F IG. 6) which are located above and below the top and bottom flanges of I-beam 80.
  • Car bufier assembly 31 and the counterweight buffer assembly are positioned between their respective rails 24, 46 at the desired lower end of travel and their modified safety mechanisms are released causing both buffer assemblies to engage their respective guide rails.
  • Preassembled elevator car 25 and counterweight 45 are hoisted into place and landed on their respective bufier assemblies.
  • Portable machine room 32 including the typical traction drive equipment, is lifted into place by the contractors crane and is suitably positioned on machine beams on the fourth floor level. As additional steel is erected floor by floor, workers install additional frames 21 together with their associated beam sections and I-beams. With the installation of each group of two frames 21, rails 24 and 46 are installed and roughly aligned. Suitable hoistway enclosing panels are installed to protect personnel from the otherwise open shaft.
  • the elevator system is extended by hoisting up the portable machine room 32 to that new level and paying out the ropes as described in the aforementioned patent.
  • This extension procedure may be followed until normal elevator service is available at the lower landings of the building and the need to service these lower landings with the herein disclosed system no longer exists.
  • the rise can either be shortened or the entire elevator system can be raised as a unit.
  • the hoist may be used to raise to the desired level the portable machine room 32 with its elevator car 25 attached as in U.S. Pat. No. 3,519,101 and with buffer assembly 31 attached to car 25 by eyebolts 76 together with counterweight 45 and its buffer assembly attached thereto in similar fashion.
  • counterweight 45 may be positioned on and attached to its buffer assembly and detached from sheave assembly 49.
  • the counterweight and its buffer assembly may then be raised after the other equipment in a separate hoisting operation. Reattachment of the counterweight to sheave 49 takes place after its buffer assembly is repositioned and it is disconnected therefrom.
  • portions of the temporary hoistway are removed and floor areas in the vertical air shaft are completed.
  • a previously unmentioned feature of the invention is the ability of the temporary hoistway structure to distribute vertical forces transmitted to the rails from buffer assembly 31 in the event of overtravel or from the normal car safety (not shown) in case of operation thereof in the event of overspeeding.
  • This distribution is through a plurality of frames 21 to the building's structural elements 22 on a plurality of floors.
  • the distribution permits the frames to be of lighter weight than they could be if such forces are not distributed since no single frame has to sustain the maximum safe load for which the rails are rated.
  • the frames are designed so that the maximum force any frame will have to sustain is predetermined. This is accomplished, as desired, by selecting the deflection per unit of force of the active span of each vertically flexible member 81 accordingly.
  • guide rails 24 are No. 1 rails with a maximum rated safe loading of 15,000 lbs. and if it is desired that no frame 21 and therefore no building floor level sustain more than an 8,000 lb. load notwithstanding a 15,000 lb. vertical force may be applied to each of rails 24, member 81 should be provided with an active span which will deflect sufficiently so that in conjunction with the elongation of the guide rails 11/15 or 73% percent of any load applied to any one frame through a rail will be transmitted to the other frames of the structure.
  • the design of structural members to accomplish this purpose is performed by straightforward structural design techniques well known to any structural designer and, for purposes of brevity, will not be explained herein.
