ABSTRACT F THE DISCLOSURE A novel method of providing lateral guidance to floors Iduring ltheir lifting Ifor the erection of build-ings, by means `of a removable, vertically extended, stiifening structure.
This invention relates to a method 1of providing lateral guidance |to iloors dur-ing their lifting for the erection of buildings by using `a vertically extended structure.
In conventional methods for lifting lloors attention was not paid suii'ciently to providing lateral stabilization. Acccrding to one method, however, the llo ors are Ilifted while being 4guided by constructions remaining as permanent components in the building, as for example elevator shafts and staircases which in such la case fare erected prior 'to the lifting of the floors. According to another method, the yguidance is effected by iron stands which are not intended to remain as permanent components in 'the building but can be placed in the spaces provided to serve for staircases and elevator shafts.
This invention is substantially characterized in that the method comprises a first operation phase wherein a laterally stiifening structure is lanchored in a cast base plate `and serves as guiding means during the lifting ci the basement lfloor and of one or some more iloors until said floors have reached their level of mounting and `are supported by vertical building elements, and la second operation phase wherein 'the structure is separated from the base plate and is secured to the next ilo'or to be lifted with which it follows during its lifting while at t-he same time being guided by the basement floor and the irs't floor or, alternatively by the irst doors already in position.
This invention relates to `a novel method of providing lateral guidance to floors during 'the erection of building structures. The method essentially comprises forming a base plate, providing a vertically extending guiding and stilfening structure, ancho-ring the lower end of said stiffening structure in said base plate, forming at least one iloor on said base plate with portions `thereof engaging 'the stilening structure in guiding relationship, sequentially lifting each iloor to its final position in the building and positioning substantially vertically extending supporting means intermediate the floors, forming at least lone additional floor yon 'the uppermost supported floor with portions engaging the stiifening structure in guiding relationship wherein said s'tiifening structure is of -a length 'at least equal t-o the *thickness 'of the floor stack increased by two storey heights, separating the lower end of the stiffening 4structure from the base plate and attaching the upper end of the stiffening structure to the upper surface of the uppermost of said additional floors and raising the lowerm'ost additional floor into position with the stitfening structure being guided by the previously supported floors.
The method according to the invention will be described in greater detail in the following, reference being had to the accompanying drawings whereon AFIGS. 1-4 show in a schematical manner diferen't operation phases of the method, and
FIGS. 5 and 6 show by way 'of example some placements of the structure.
ICC
According to the method of the invention, the irst step is 'to pour in conventional manner a base plate 9 and to pour thereon the basement iloor 2a. Prior to the lifting `of the latter by jacks in known manner, a first part of a laterally stitfening structure 3 is mounted on the base plate on the foundation, preferably of storey height. The said structure may comprise two separate sec-tions each placed on one of the outer surfaces of the basement iloor 2a, or the structure may comprise different parts placed in openings provided in 'the basement iloor 2a as shown in FIG. 5, or i-t may be a single section dis-posed directly in 'the centre of the basement oor as shown in FIG. 6. This structure and these structures respectively may, for example, Ibe iron pillars adapted to take up possible lateral forces in the floors. When the laterally stitfening structure sections are placed at the edges of the iloors, iron guides Aare bolted in the iloors to guide the floors along 'the structure sections.
After the basement floor 2a is lifted 'by jacks to its level of mounting, forms are made for the future staircases, elevators shafts and/or stiffening walls 6 whereafter these elements are poured. As an alternative, the said elements may be pre-fabricated units to be mounted in their positions. This part of the method is shown in FIG. l.
T-he basement floor 2a being fixed in the same manner, a plurality `of floors 2b is poured upon the same, whereafter the jacks 1 are placed below the basement -floor 2a yand provided with extension rods to extend through openings in the basement floor. The jacks 'and rods press the iloor stack upwards by one storey, after the laterally stilfening structure 3, 4 has been lengthened by an additional storey height. The form side which has no contact with the floors 2b at the walls of the stiffening elements, tha-t is staircase walls elevator shaft walls and/ or `other walls is lifted in connection with the floor lifting in that it is anchored in the floor stack.
After 'the lifting lof the iioor stack, the lowermost iloor is ixed on bearing elements whereafter laterally stiffening walls 6 are poured a further storey height. The described part of the method constitutes the first operation phase of the method `and is carried out according to FIGS. 2 and 3 until the structure comprises the three parts 3, 4 and 5. As appears from the said figures, laterally stiftening walls `are poured and inserted respectively at the end of said operation between the base plate 9 and the basement o'or 2a as well as between the latter and the rst of the floors 2b.
Thereafter follows the second operation phase of the method wherein the structure 3, 4 and 5 is separated from its foundation on the Ibase plate 9 land lsecured to the uppermost floor 2b Yof the remaining floor stack, for example by means of a beam 8. Upon lifting the iloor stack the structure follows along lone storey, as shown in FIG. 4, and is guided by the stiffened part of the building, i.e. both in the basement floor 2a and in the first hoor 2b.
The pouring and insert-ing respectively of laterally stiiening walls 6 is then carried out in the above-described way. As the erection of the building continues, the structure follows along storey by storey until |the building is completed. The structure can then be dismantled for use on another building site.
The laterally stilfening structure need not be higher than the thickness of the floor stack increased by two storey heights. The structure may, of course, be higher in cases where it is practical `and necessary, for example, to pour the walls one storey later than described above. The structure may also be constructed such, that walls for two s'toreys can be poured simultaneously, for example for lthe second and third storey, for the fourth and fifth storey, and so on. The same constructions for lateral stiifening may also be used even 4if no permanent walls are poured before the iloors were lifted to full height in all storeys. In such a case, however, the laterally stiftening constructions must `be made substantially stronger than otherwise required.
