Abstract
Description
- The present invention concerns a method and a device for mounting floor-carrying horizontal beams between multi-storey steel columns.
- The invention deals with erection of multi-storey buildings and particularly the design of columns of preferably orthogonal structural frameworks of such buildings, said frameworks including multi-storey columns of steel and joining beams of concrete or steel. Normally, such frameworks are made with steel columns which, prior to mounting, are provided with weld-connected shoulders, steel plates or brackets for supporting and holes for bolt-connecting the beams, respectively. Often the beams, whether they are made of steel or concrete, are pivotably supported on the column supports, combined with a certain torsional restraint however in relation to the columns. In other cases there is a need to make the orthogonal framework stiff, e.g., in a façade having capacity to transmit horizontal forces in the plane of the framework. The beam ends are then fixed to the columns, involving that beam and column must be rigidly connected in regard of momentum.
- Examples of the above mentioned art appears from SE-B-8700147-5 in which are described and shown frameworks comprising multi-storey steel columns, horizontal concrete spandrel beams and precast concrete floor elements. To the columns, which normally have H- or I-sections, supporting steel plates are attached in advance between the column flanges. Apart from the strict requirement of accurate location of such plates, since they define the floor level their mere existence between the column flanges leads to difficulties when a façade spandrel beam shall be lowered between the column flanges, particularly when the façade beam has such dimensions that it cannot simply be inclined suffiently to pass support plates at a higher level.
- The object of the present invention is to avoid said disadvantages as well as to further develop the state of art. This is achieved in that the invention has been given the characteristic features stated in the claims below.
- According to one aspect of the invention, the previously utilized supporting steel plates, which were attached at defined levels along a column, have been replaced by supporting means having a fixed length, said supporting means obtaining a direct bottom support at an already defined level and providing an upward support for a horizontal beam at a supporting level which, thus, is likewise pre-defined. By prefabrication of supporting means, as well as horizontal beams, and the dimensional accuracy resulting therefrom, each floor level will be most accurately defined by addition of the respective heights of supporting means and beams.
- As a variation, supporting means can be used having lengths shorter than but close to the one defined as above, said supporting means by means of height adjusting means obtaining an indirect support at the level already defined and providing an upward support for a horizontal beam at a level which is adjustable by means of said height adjusting means to be the correct support level for a horizontal beam. In this way a simple possibility of adjustment is achieved under maintenance of the other advantages of the invention.
- According to another aspect of the invention, each steel column is composed from a multi-storey high column having a constant cross-section (here denoted core-column) and supporting means connected thereto, said supporting sections extending from the bottom surface of a beam at one floor level to the corresponding top surface of a beam at the underlying floor level, or, in case of a foundation to that foundation, so that, when mounting a framework, after the core-columns have been erected, supporting means and beams can be stacked on top of each other in pace with the supporting means being connected to the core-columns.
- Whichever aspect of the invention is considered, a number of important advantages are being achieved, such as an essentially simplified art of assembly resulting in great possibilities to obtain high dimensional accuracy in the vertical direction. Additionally, the steel columns will be imparted an essentially increased stiffness and load bearing capacity along their free zone between the connected beams due to the supporting means connected thereto along these zones. Also, new possibilities are created to provide rigid connection of horizontal beams to the column composed of core-column and supporting means at the top edge of the beam as well as at its bottom edge. Further, possibilities to achieve composite co-action with concrete are provided when the supporting means are connected such that laterally closed channel-like spaces are created between the supporting means and the core-columns, and into said spaces is injected a hardening casting composition.
- When erecting multi-storey columns it is an advantage if these can be brought directly to the building site in pre-cut lengths without first needing to be prepared at a welding workshop for accurate attachment of support devices. Since the supporting means according to the present invention sets aside the need of such preparation of columns, the preparation at the welding workshop is limited to the supporting means which are substantially more easy to handle, but require high dimensional accuracy. The sum of the heights of the supporting means and the beam ends define the storey hight at so called "drop in" assembly, if such is utilized without particular level adjustments being done storey-wise. After the core-columns have been located and connected to the foundation the supporting means are placed against the support, which, after the first floor, is constituted by the top surfaces of the beams.
- Before mounting of the beams the supporting means are provisionally connected to the column by means of clamps, bolts or spot welds. Connection by strength weld at this stage normally takes place only at those locations of attachment that are not accessible after mounting of the beams, this in order to make the main welding work independent of the mounting. After mounting of the beams of the first floor level follows the mounting of at least the floor slabs closest to the columns and thereafter the final (weld) connection of the underlying supporting means to the core-column. Using the floor as a platform the erection procedure is then repeated floor by floor.
- An essential technical effect arises when the supporting means by welding along their entire lengths or parts thereof are connected to the core-columns, whereby the cross-section, bending stiffness and capacity to withstand normal forces of the free cross-sections of the composite parts of the columns are considerably increased as compared to the corresponding capacities of the core-column. If buckling is a critical design criteria the cross-sectional area of the core-column therefore may be reduced correspondingly. If, on the other hand, the compressive stress in the steel cross-section is decisive, the cross-section of the core-column can be reduced only to the extent a part of the normal force is channeled through the beam ends connected to the core-column between the supporting means. Thus, if the beam ends and their connections to the composite parts of the columns are made such that the beam is rigidly connected to the columns, i.e., rigidly connected at its upper edge as well as at its bottom edge, the function of the beam ends as parts of the columns is ensured. The fixation of the beam ends to the columns in turn leads to an orthogonal framework having a considerable in plane diaphragm capacity as regards the transfer of horizontal forces. In certain cases it may be difficult to perform sufficient weld connections at the interface between the beam top surface and the supporting means so as to be in parity with the moment capacity of the rest of the composite column. In such cases, the supporting means may be completed with a reinforcement bar or a bolt connected thereto which is anchored by injected grout fill or a screw, respectively, in the underlying beam.
- To the extent the supporting means are connected to the core-column in such a way that they, together with core-column, define a laterally closed, vertically extended space along parts of the column, the invention offers another technical effect of importance, viz., in that this space may be injected with a concrete grout which after its hardening will act composite with the column, the load capacity and stiffness thereof being further essentially increased. In case the façade beams are of concrete a space is advantageously left between the beam ends and the web of the columns such that also at that location is formed a vertical, laterally closed space which may be injected with a concrete grout. Also in cases where a façade beam is of steel the beam ends may be designed such (e.g. by transverse web stiffening plates) that corresponding spaces are formed between the beam ends and the core-column. In both cases it is possible to perform the grouting operation in one sequence after the whole or a part of the building has been mounted, especially if it is monitored that the spaces between supporting means and core-columns have connection to adjacent spaces between the beams and core-columns. In addition to the load carrying advantages of grouting said spaces, also considerable heat and noise insulation is achieved.
- The invention will be discribed in the following, reference being made to the accompanying drawings, wherein:
- - Fig. 1 is a prespective view of a part of a framework of a multi-storey building seen from inside,
- - Fig. 2 is a view showing at an enlarged scale a detail of a framework similar to the one according to Fig. 1,
- - Fig. 2a is a view showing a detail similar to the one according to Fig. 2 but concerning an alternative method of mounting a supporting means,
- - Figs 3 and 4 are views showing at a further enlarged scale a vertical and a horizontal section, respectively, through the column of Fig. 2 in the area of a beam support, and
- - Figs. 5 and 6 are views showing a vertical and a horizontal section, respectively, through a portion located at a higher level of the column of Fig. 2 in the area of the upper side of a façade beem.
- Fig 1 shows composite frameworks comprising vertical, multi-storey
high steel columns horizontal façade beams horizontal beams 4 of the frontal façade have supportingsurfaces 6 for floors 7, comprisingprefabricated floor elements 8, and thefaçade elements 5 of the gable façade of the building have a longitudinally extendingrecess 9 at floor level adapted for jointing of afloor element 8 for transmittal of shear forces. Thefaçade beams section columns corner column 3, comprising two inter-connected U-sections. In any case each column has twoopposed flanges web portion 13. - According to the state of art the ends of the
beams flanges - The principle of the invention appears more closely from Fig. 2 showing a portion of a core-
column 2 of Fig 1 partly cut off, portions of twofaçade beams 4 connected thereto and somefloor slabs 8 supported on one of thefaçade beams 4. Thefaçade beam 4 to the right of Fig 2 is connected at its right-hand end to thecorner column 3 of Fig. 1 while theleft façade beam 4 is connected with its left-hand end tocolumn 1 of Fig 1. In Fig 2 are shown two supportingmeans 14 of which the lower one 14a with its non-shown bottom end supports against a fixed bedding, e.g., in the shape of the upper surface of anunderlying façade beam 4. In the example shown, the supportingmeans 14 have the shape of U-sections, theflanges flanges column 2 and theweb portions 17 of which are turned away from theweb portion 13 of the core-column. Preferably, the supportingmeans 14 are provided at both ends with supportingplates plate 18 of the lower supporting means 14a is resting the lower edge of afaçade beam 4 on which in turn rests the upper supporting means 14b with its supportingplate 19. - In practice, mounting is performed such that one supporting
means 14 is erected on the bedding in question and is provisionally connected to the core-column. This, e.g., can be achieved by means ofspot welds 20 against theflanges façade beam 4 is lowered onto the supportingmeans 14 and the entire orparts 8 of a floor are placed on the supportingsurface 6 of the façade beam. Final connection of a supportingmeans 14 to a core-column takes place by means ofstrength weld 21, as is shown at the supportingmeans 14a which is loaded by afaçade beam 4 and at leastparts 8 of a floor 7. - As previously mentioned, the supporting
means 14 are suitably prefabricated to obtain accurate dimensions. When the façade beams, as in the example shown, comprise concrete beams, also these beams at manufacture are provided with accurately located lower supporting plates 22 (Figs. 3 and 4) and upper supporting plates 23 (Figs 5 and 6). In addition, a U-section 24 against which the supportingplates - If, for manufacturing reasons, it should be impossible to make all supporting
means 14 of an exactly equal length, it is preferred to make all supporting means shorter than the fixed length. One reason for this, of course, is that a too great length would make the supporting means unusable without cutting. For certain mounting reasons it may also be suitable to make the supporting means shorter than the fixed length. In Fig. 2a is shown how the mounting of a supporting means 14′ is performed in such cases. On the upper surface of afacade beam 4 is placed awedge 40 on which a supporting means 14′ is erected. By means of thewedge 40 the level of the upper side of the supporting means 14′ is adjusted such that said upper surface is located at the correct level to serve as a support for ahorizontal beam 4 placed thereon. When the supporting means 14′ has been adjusted at the correct level it is welded to theflanges column 2 in a similar way as described above, thereafter thewedge 40 is removed. - For connection between a
façade beam 4 and an underlying supporting means 14a ahole 25 may be provided in the supportingplate 18 of the supporting means, said hole being adapted to co-operate with a stud 26 (Figs. 3 and 4) projecting from the underside of the façade beam, said stud being threaded into a threaded hole in thesupport plate 22 at mounting. At its top thefaçade beam 4 is connected by welding of its supportingplate 23 and by intermedience of around iron 27 to theweb portion 13 of the core-column before an upper supporting means 14b is arranged on the supportingplate 23 of the façade beam (Figs 5 and 6). In order to obtain satisfactory connection between the supportingmeans 14 and thefaçade beam 4 also in this area if accessibility for welding is bad a hole and a stud (not shown), or, a bolt joint may be provided between them in a similar way as at the upper side of the supporting means. - As shown in Fig 2, between a supporting
means 14 and theweb portion 13 of a core-column a laterally closed space is formed having the shape of avertical channel 28 between the supporting means and the column. This channel may suitably be injected with a hardening grout, such as concrete, in order to obtain composite action with the supporting means and the core-column. In such case it is of course advantageous if the stud orstuds 26 projecting into thechannel 28 are of the finned reinforcement bar kind for improved co-action with the injected grout. - In order to keep the supporting means levelled with the
flanges vertical channel 28 and the end areas of over and/or underlying façade beams some kind of spacing means may be arranged between the supporting beams and the core-column. One example of such a spacing means 29 is shown in Figs. 3 and 4 to be arranged between the supportingplate 18 of the supporting means and theweb portion 13 of the core-column. - As appears from at least Figs. 3-6 there is also a
vertical space 13 between the ends of the façade beams and theweb portion 13 of the core-column. According to the present invention thisspace 30 is in communication with the over and/or underlyingvertical channel 28, such that a plurality of channels and spaces can be injected simultaneously. - At its ends the
façade beam 4 is thinner than the distance between theflanges flange 11. In such case, the U-section 24 can be welded (at 32) to theflange 11 so that also the beam end is effectively incorporated in the composite column including also the core-column and the supportingmeans 14. For the sake of continuity in the composite column also the upper supportingplates 18 are welded (at 33) to the lower supporting plate 22 (Fig. 3) of the superposedfaçade beam 4 and the lower supportingplates 19 of the supportingmeans 14 are welded to the upper supportingplate 23 of the underlying façade beam 4 (Fig. 5). - The space formed between the beam end and the
flange 12 of the column can easily be sealed so that no injection grout leaks out. - In order to obtain the desirable channel forming space between a supporting means and a core column the supporting means may, of course, have other cross-sections than U-shaped ones, particularly if the core-column itself has flanges as in the example described. As the most simple case, thus, a plane plate can be contempled, said plate being welded to the flanges of the core-column.
- Even if the invention has been described in connection with columns having H- or I-section, it may as well as be applied to columns having a closed cross-section, for instance □-section.
