Description

BUILDING CONSTRUCTION This invention relates to building constructions and in particular the construction of multi-level buildings and the provision of lifting facilities in such buildings during the construction phase.
During the construction of multi-level buildings, there is a need to transport construction and other personnel, and materials from ground level to the various floors of the building. With such building constructions it is usual to utilise one or more partially constructed lift wells in the transportation of personnel and materials. Typically, a lift car is located in each partially complete lift well being used for such purpose and a control facility (which includes a lift motor) is temporarily installed within and towards the upper end of the lift well for raising and lowering the lift car as required. As the building progresses upwardly, the control facility is progressively elevated within the lift well so as to provide access to additional levels within the building.At or towards the end of the construction stage of the building, the control facility within the lift well is removed and replaced b a permanent control facility located over the top of the lift well.
There are several disadvantages with the usual arrangement of temporarily locating a control facility in a lift well. One such disadvantage is that there is a limitation to the size of the control facility that can be installed in the lift well owing to space limitations within the lift well, and so there can be no possibility of later employing that control facility on a permanent basis at the top of the lift well. A further disadvantage is that access within the lift well is somewhat limited and the removal of the temporary control facility from within the lift well conflicts with operation of the permanent lift. A still further disadvantage is that the presence of the controls facility within the lift well provides an obstructions which limits the upper extent of travel of the lift car within the well.
It is an object of the present invention to overcome or at least reduce the above disadvantages by locating the control facility outside of the lift well.
Throughout the specification shaft equipment shall be taken as referring to all facilities normally provided in a lift shaft or lift well to support, guide, control and limit the movement of a lift car while the term lift car shall be taken as referring to any form of platform which can be installed in a lift shaft for the transportation of goods and material in that shaft.

The invention will be more fully understood in the light of the following description of several specific embodiments. The description is made with reference to the accompanying drawings of which: Figure 1 is a schematic view showing a control facility according to the first embodiment supported on a completed portion of a lift well of a building prior to the control facility being raised; Figure 2 is a schematic view of the embodiment of Figure 1 subsequent to the raising of the control facility; Figures 3a,b,c,d,e,f,g,,h,i,j,k,l and m indicate the procedures involved in utilising the first embodiment in the construction of a multi-level building; Figures 4 and 5 are schematic views of a third and fourth embodiment respectively which is utilised with a form of jump forming technique for forming the lift well;; Figure 6 is a schematic view showing a control facility according to a further embodiment supported on a completed portion of a lift well of a building, prior to the control facility being raised; and Figure 7 is a schematic view of the embodiment of Figure 6 subsequent to raising of the control facility.
The first embodiment, which is shown in Figures 1 and 2 of the drawings, is directed to provision of lift facilities in a multi-level building which is under construction and in which there is a lift well constructed from reinforced concrete.
The building is shown (schematically) in a partially constructed condition in Figures 1 and 2 of the drawings and includes floors 11 and a plurality of lift wells 1 extending between the floor in conventional manner. Each lift well is defined by walls 15. At each floor level 11 there is a lobby 17 onto which each lift well 13 opens by way of opening 19 in the adjacent wall 15 of the lift well.
The walls 15 are formed from reinforced concrete and have columns 21 of steel or other suitable material embedded therein.
In the construction of each lift well, the lower portion of the lift well corresponding to the basement and ground floor levels of the building, is first formed with the columns 21 embedded in, and extending upwardly beyond, the completed section of reinforced concrete defining the walls of the lower portion of the lift well.
A control facility 23 is positioned over, and supported by, the lower portion of the lift wells. The control facility 63 can be fabricated in position on top of the lower portion of the lift wells or can be prefabricated as a module and then installed on the lift wells. The control facility comprises a plant room 25 which is weatherproof and which remains in place over the lift wells upon completion of the building. The plant room 25 comprises lower and upper portions 27 and 29 respectively each of which has a height of approximately one floor level. The lower portion 27 of the plant room accommodates a lift control mechanism (not shown) for raising, lowering and generally controlling movement of a lift car 31 positioned within each lift well. The upper portion 29 of the control facility accommodates the upper sections of the columns 21, as will be explained in more detail later.The lift control mechanism includes a drive motor corresponding to each lift well to which the lift car 31 is connected by means of a cable 33 in conventional manner. Guards (not shown) are provided around the cable at locations within work spaces in the lift well. The drive motor may be either a permanent motor intended to continue to operate as part of the lift control mechanism after completion of the building or a temporary motor intended to be replaced by a permanent motor later in the course of construction of the building.
A raising means 37 is connected to the control facility 23 and is operable to raise the control facility above the lower portion of the lift wells a predetermined extent corresponding approximately to the level of one floor. In this embodiment, said raising means 37 comprises the columns 21 and a jacking means 39 co-acting with each column 21. Each jacking means 39 comprises a pair of hydraulic rams 41 arranged to co-act with the upper section of the respective, which upper section is column accommodated within the upper portion 29 of the plant room. The hydraulic rams 39 are positioned on opposing ends by a saddle 45 which can be positioned over the support end of the column. the hydraulic rams 39 are fixed to part 43 of the plant room. With this arrangement, the control facility is raised relative to the lower portion of the lift wells upon contraction of the hydraulic rams. The hydraulic rams are contracted at a controlled rate and elevation of the control facility is monitored to ensure that there is no excessive tilting of the control facility during its elevation.
When at the upper extent of its elevation, the control facility is releasably locked to at least one of the columns 21 by way of locking means (not shown) such as locking bolts which can be used to securely fix the control facility to the column.
The walls 15 of the lift wells are extended upwardly towards the control facility after completion of such elevation.
The columns 21 are extended upwardly each time the control facility is raised. This is accomplished by mounting an extension piece 21a on top of each column.
This procedure is carried out in the upper portion 29 of the plant room. The extension pieces 21a are connected to the columns 13 in any suitable manner such as bolt splicing. The hydraulic rams can then be connected to the upper end of the extension pieces 21a by way of the saddle 45 and then operated to again elevate the control facility, but of course only after the locking means have been released so that the control facility is no longer fixed to the columns 21. A further upward extension of the lift well can then be formed. The control facility is elevated upwardly relative to previously formed extensions of the lift wells on a number of successive occasions and an upward extension of each lift well is formed on each such occasion until such time as the lift well reaches its required height.
The floors 11 of the building are formed progressively one above another as formation of the lift wells progresses upwardly.
The control facility 23 supports a canopy or other cover 44 which extends from its sides to overlie the lift wells and so provide shelter for the work platform.
The cable 33 connecting the lift car 31 to the lift control mechanism in the plant room is adjusted from time to time to extend the upper limit of travel of the car with upward movement of the control facility.
Shaft equipment can be installed in the lift well as it is being extended upwardly to facilitate access to floor levels formed below.
With this arrangement, access to the floor levels of the building is achieved relatively early in the development of each floor level b means of the lift cars to facilitate transportation of personnel and materials to the floor. This earlier provision of the lift facilities reduces the reliance which is normally required on temporary hoisting facilities for the transportation of personnel and materials to the partially completed floors.
As each floor 11 is formed, an opening 53 is provided in the lobby 17 of the floor. The opening 53 provides access between the lobby 17 of the floor formed most recently and the lobby of the floor immediately below, to facilitate transfer of personnel and materials between the two floors. The opening is advantageous because at this stage, access between these two floors is not possible by means of the lift cars owing to limitations to the extent of their upward movement. A hoist (not shown) mounted on the underside of the control facility can be utilised to facilitate transfer of personnel and materials through the opening between the two floors.
Access for personnel between the uppermost floor and the control facility can be provided by any suitable means such as stairs, temporary staging, scaffolding, temporary hoists or the like while raising of materials to the form work can be achieved by use of conventional temporary lifting facilities.
While in this embodiment the columns 21, which form part of the raising means 37, are embedded in the walls of the lift well, it should be understood that they can be positioned in any other suitable location, such as externally of the lift wells.
The upward extensions of the lift wells may be formed using any suitable forming technique such as "jump forming" ring" or "slip forming". . In this embodiment, a formwork structure 46 is employed for such purpose. The formwork structure includes external and internal forms 47 and 49 respectively. The formwork structure defines an upper work platform 51 for workmen and has a retention means (not shown) for releasably engaging the walls of the lift wells to support the formwork in position. The formwork is raised in step-by-step fashion as required to facilitate formation of the upward extensions of the lift wells.
Figures 3(a) to 3(m) illustrate the fashion in which a building of six levels can be constructed utilising the lifting techniques provided by the first embodiment using a slip form or jump form technique whereby the lift wells 13 are constructed by conventional techniques for the basement, ground level and first level as shown at Figure 3(a) and has upstanding columns 21 installed therein which are provided with temporary bracing 59 at their upper ends. The second level is then formed by conventional techniques as shown at Figure 3(b) and the bracing 61 is removed. The control facility is then installed over the top of the lift well as shown at Figures 3(c) and 3(d). The control facility is then installed over the top of the lift well as shown at Figures 3(c) and 3(d).The control facility is then raised from the lift well as shown at Figure 5(e) to enable formation of the next level of the lift well as shown at Figure 3(f). The control facility is again raised as shown at Figure 3(g) to enable formation of the next level of the lift well as shown at Figure 3(h). The control facility is again raised to the next level as shown at Figure 3(i) to enable formation of the next level of the lift well as shown at Figure 3(j).The control facility is then raised to its upper most level as shown at Figure 3(k) to enable completion of the lift well to its upper most level as shown at Figure 3(1) and on completion of that level the formwork is removed using lifting means (not shown) supported on a track assembly overlying the lift well, and the lift plant room is lowered onto the upper most level of the lift well as shown at Figure 3 (m). During the construction phase of the lift well the floors below the lift well are formed progressively one above the other and the lift cars are utilised to service the formed floors on the completion of the installation of the shaft equipment within the lift wells as the lift well is increased in height.
In the first embodiment, the control facility is elevated in step-by-step fashion by means of a jacking system which co-acts with the columns 21 extending upwardly of the walls of the lift wells. It is possible, however, to elevate the control facility in such fashion by means of a jacking system which co-acts with the walls of the lift wells. The second and third embodiments of the invention are directed to such an arrangement.
In the second embodiment, which is shown in Figure 4 of the drawings, the walls of the lift wells are formed using a jump-forming technique known as "VSL" system which is the subject of Australian Patent No. 502680.
With the VSL jump forming technique, a formwork structure 61 for the walls of the lift wells is progressively elevated under the influence of a plurality of vertically extending members 63 such as hydraulic cylinders. The formwork structure is adapted to receive and support the control facility 23. With this arrangement, the control facility is raised concurrently with the formwork as it is moved upwardly.
In the third embodiment, which is shown in Figure 5 of the drawings, the walls 15 of the lift wells 13 are formed using a jump forming technique known as "LUBECCA" system which is the subject of Australian Patent Application No. 18541/88. With the LUBECCA jump forming technique, a formwork structure 67 for the walls of the lift well is progressively raised under the influence of a jacking means 69 in the form of hydraulic rams, at least two hydraulic rams in each lift well. Each hydraulic ram 69 has a cylinder portion 70 and a piston portion 72. The jacking means 69 support a frame 71 from which forms 73 are suspended, and to which the piston portion 72 of each ram is connected.Each cylinder portion 70 is supported on, and fixed to, a jack support 75 which extends between two opposed walls of the lift well and is provided with engaging means such as retractable feet 77 for releasably engaging means such as pockets 79 provided in the opposed walls of the lift well. The feet 77 are biased into an engaging position with respect to the pockets 79.
A support means 76 is positioned above the jack support 75 and is connected to the frame 71 by way of rigid posts 74.
The support means 70 is provided with engaging means 78 such as feet for releasably engaging pockets 79 not occupied by the feet 77 while the jack support is subsequently disengaged and raised by contract of the jack means to the position close to the support means 76 to engage the same pockets occupied by the feet of the support means. Concrete for an upward extension of the walls of the lift well can then be poured into the spaces between the forms and the jacking means subsequently extended to raise the forms into position for pouring of the next upward extension of the lift well.
The control facility 23 is mounted on top of the formwork and is elevated as the formwork is moved upwardly. The need for a separate mechanism for raising the control facility is therefore avoided.
The next embodiment, which is shown in Figures 6 and 7 of the drawings, is directed to the provision of lifting facilities during the construction of a multilevel steel framed building in which the core of the lift well 13 is formed of a steel frame which may if desired be formed of intermediate modular frames.
According to the embodiment the basement and ground level portions of the lift wells 13 are constructed and the associated floors are also constructed. Each lift well is then constructed such that it extends at least one floor level above the existing floor. The control facility for lifts in the building is then fabricated over the existing top of the completed portions of the lift wells. Alternatively, the control facility is prefabricated and lowered into position over the existing top of the lift wells 11. The top of the completed portion of the lift well is formed with a plurality of upstanding columns 81 over which the control facility 23 is located whereby the columns are received within the control facility.As with the previous embodiments, the control facility comprises a plant room having lower and upper portions 27 and 29 respectively each of which having the height of approximately one floor level. The lower portion accommodates the lift control mechanism 83 required for raising and controlling the movement of the lift cars within the lift wells. The upper portion of the lift plant room receives the upper portions of the columns. Lift cars 31 are installed in the bottom of the lift wells either prior to, or subsequent to, installation of the control facility. The lift cars are connected to the lift control mechanisms provided in the lift plant room and the appropriate lift shaft equipment is installed within the lower portion of t he lift wells.
The lift plant room is associated with a set of jacking devices 85 (shown schematically in the drawings) which are provided between the more recently formed floor level and the lower edge of the sides of the lift plant room.
On completion of the most recently formed floor 11a and the installation of the columns 83 within the upper portion of the lift plant room, the jacking devices 85 are extended to raise the lift plant room to a new floor level as shown at Figure 7. Locking means (not shown) are provided between the lift plant room and the columns, and are operable to retain the lift plant room in position on the upper most portions of the columns. When at that position the next floor level is constructed, extension pieces 81a are installed to the upper ends of the columns 81 in the upper portion 29 of the lift plant room.In addition the shaft equipment can be installed in the newly formed portion of the lift well in order to provide access between the floor levels completed and the lift cars 33 to facilitate transportation of goods and personnel between ground level and the floors. The sequence described above is continued until the upper level of the lift well has been reached and until completion of the uppermost floor level. On completion of the uppermost floor level the jacking devices 85 are removed and the lift plant room is fixed in position to the top of the lift well as a permanent fixture.
