Definitions

  • This invention relates to a connection arrangement for connecting a vertical element, such as a column or a wall element, and a horizontal element, such as a beam, to each other according to claim 1.
  • the invention also relates to a connection comprising a vertical element, such as a column or a wall element, and a beam.
  • the hidden bracket is very challenging, because it must transfer very high loads from the beam to the column in a very small space.
  • the bracket connection transfers a vertical load of the beam to the column. This load acts in the different construction stages at different magnitudes. The load acts in general in the downward direction but in the installation situation it may momentarily be also directed upwards.
  • the bracket connection is also subject to a horizontal load in the longitudinal direction of the beam, which horizontal load may act in opposite directions. Additionally, a torsional moment tending to rotate the beam acts on the bracket connection. The bending moment of the end of the beam is not in general transferred by hidden brackets, as it constitutes a very challenging structure for which a well-functioning application has not yet been developed.
  • the column in general comprises a column part fastened to the column, which column part transfers and fixes the forces from the beam to the column.
  • a beam part is fastened to the beam, which beam part transfers the loads of the beam to a tongue part of the column part.
  • the tongue part forms the most challenging structure of the connection, because it is subject to the highest loads and it is required to have many functional properties especially in the installation stage of the connection.
  • bracket structure As the bracket must be suitable for frame structures in the connections of which the material of the beam and the column may change even within the building and even at different ends of the same beam.
  • the hidden bracket system must therefore adapt to the requirements of the building frame. Therefore, it has become a general requirement that the beam part of the bracket connection must fit a concrete, composite and steel column without the structure of the beam part being changed. This requirement is not met by the current commercial bracket systems, as they are frame material specific.
  • connection arrangement is presented, by means of which connection arrangement a concrete beam or a composite beam may be connected to a composite column or a steel column using the same connection arrangement.
  • the frame material of the building thus no longer poses an obstacle to the use and fitting of the bracket connection together with different frame structure materials.
  • the vertical load of the beam is transferred from an end plate of the beam part by the tongue part of the bracket, wherein the surface of the column is provided with a metallic projection, generally a rectangular-shaped plate, over which the bracket parts of the end plate of the beam are supported.
  • This structure functions in general quite well and transfers the vertical loads reliably to the column.
  • the beam is always installed by lowering from above onto the tongue part of the bracket, and the beam is not fastened in any way to the tongue part, but the weight of the beam and the projection parts of the tongue part hold the beam in its place.
  • the continuity of the beams forms a situation where, in the installation situation, the end of the beam is also subject to lifting forces.
  • the lifting force has in general been removed by installation support.
  • locking of the bracket also for the force lifting the end of the beam is introduced, whereby the installation support is not needed.
  • Horizontal forces of the beam are transferred by the projections of the tongue part of the bracket, behind which projections the abutment parts of the beam part are supported.
  • These abutment parts function generally well, but they all have one problem: the beam must move to the extent of the tolerance clearance of the connection before the abutment parts are supported to each other and begin to transfer the horizontal load.
  • locking of the bracket immoveable for forces in the longitudinal direction of the beam is introduced. The locking is also used for transferring the lifting force.
  • the transfer of torsional moment of the beam to the column is the most challenging property of the hidden bracket connection.
  • the installation clearance is required because the abutment surfaces of the beam part must fit the tongue part as the beam is installed from above onto the support surfaces of the tongue part.
  • the beams, the columns and the bracket parts generally have small manufacturing variations, whereby the parts are not fully in the designed dimensions. Therefore, between the abutment surfaces of the connection, there must be an installation clearance compensating for these variations and allowing the connection to be installed.
  • the torsional moment of the beam is transferred by these very same abutment connection parts, requiring that the connection parts should be in contact with each other. If some clearance remains in the connection, it may still transfer the torsion, but it causes at the same time harmful rotation in the beam, which is often not allowable or desirable.
  • the requirements are thus mutually exclusive, because transfer of the torsional moment requires contact between the connection parts, while installation of the connection requires a clearance between the same parts.
  • a solution is presented, by which solution the clearance for the abutment parts of the connection and the transfer of the torsional moment are solved in such a way that there is a sufficient installation clearance in the connection in the installation situation, but at the end of installation the connection parts come into contact against each other as needed for transferring the torsional moment, such that a small clearance is provided between them. Thereby no harmful rotation is caused in the connection in the end situation, and it is also locked for the torsional moment.
  • bracket structure is formed, by which bracket structure the beam-column connection may be made with a hidden bracket which does not need installation support removing the torsional moment and at the same time it transfers the torsional moment without harmful rotation of the beam.
  • Patent FI83358 discloses a rectangular-shaped tongue part, wherein between the tongue part and a slot of the end plate of the beam part there are vertical abutment surfaces, according to the patent transferring the torsional moment. This is true, but only theoretically, if the abutment surfaces of the beam part and the support surfaces of the tongue part are in tight contact with each other. However, the installation tolerance problem has not been solved in the patent, i.e. how the abutment surfaces of the slot of the beam part and the tongue part can be installed tightly against each other, when there is manufacturing variation in the structures.
  • Patent EP 1334244 discloses a rectangular-shaped tongue part (like patent FI83358 ), but this bracket has not been designed for transferring torsional moment.
  • the commercial applications of the patent and its bracket do not allow torsional moment for the bracket, and no abutment surfaces receiving the torsional moment have been formed in it due to large clearances of the connection surfaces of the bracket.
  • the commercial application of the patent uses installation support that removes the torsional moment.
  • connection arrangement for a vertical element, such as column, and a beam to each other.
  • the connection arrangement comprises a beam part to be fastened to the end of the beam and comprising an end plate having a downwardly open slot, at the bottom of which there is an abutment surface.
  • the connection arrangement further comprises a column part to be fastened to the vertical element, which column part comprises a tongue part having a support surface against which the abutment surface of the slot is arranged to be supported to receive a vertical load.
  • the object of this invention is to provide an improved connection arrangement for connecting a vertical element, such as a column, and a horizontal element, such as a beam, to each other.
  • connection arrangement comprising a beam part to be fastened to an end of the beam, which beam part comprises an end plate in which there is a downwardly open slot, at the bottom of which there is an abutment surface, and a column part to be fastened to the vertical element, which column part comprises a tongue part having a support surface against which the abutment surface of the slot is arranged to be supported in order to receive a vertical load when the beam part has been installed onto the column part.
  • the lower abutment surfaces of the slot are partly vertical and the lower support surfaces of the tongue part are partly vertical.
  • the column part comprises a fastening part provided with an internal thread and the beam part comprises a horizontal plate provided with a screw hole, through which a screw is turned onto the thread of the fastening part to prevent horizontal and vertical movement between the column part and the beam part.
  • the beam part comprises a U-shaped housing, the ends of its sides being fastened to the back surface of the end plate on either side of the slot, and the horizontal plate is arranged in a space defined by the housing and the end plate and fastened to the housing and to the back surface of the end plate.
  • connection arrangement according to the invention, there are normal installation clearances required during installation. At the end of installation the connection arrangement can be locked by the connection surfaces transferring the torsional moment without harmful rotation occurring in the beam.
  • One embodiment of the invention specifically relates to a bracket connection between composite and steel columns and composite beams.
  • the connection may also be used for connecting concrete beams.
  • a new kind of tongue part of the column part is used, onto which tongue part the beam part is lowered.
  • the slot of the end plate of the beam part and the internal structure of the beam part have been formed in such a way that the requirements relating to the installation clearances and to the torsional moment may be reliably satisfied.
  • the tongue part and the beam part of the connection are shaped in such a way that different beam and column materials may be connected by means of the connection. The implementation of the tongue part and the end plate of the beam part thus allows different frame materials got the beam and the column with one and the same configuration of the tongue part.
  • the installation tolerances and clearance of the connection in the installation situation i.e. in a situation where the connection arrangement has not been locked immovable, are achieved such that the shape of the tongue part of the column part and the shape of the slot of the beam part form the clearance of the connection which is required at the beginning of installation as the beam part is installed from above onto the column part.
  • the width of the lower part of the slot of the beam part is greater than the width of the upper part of the tongue part, whereby the tongue part has space in the horizontal direction inside the slot at the beginning of installation.
  • the clearances of the connection are removed due to the shape of the tongue part and the shape of the slot of the beam part, and at the end of installation the support surfaces of the tongue part and the abutment surfaces of the slot come against each other or to a distance of the installation clearance from each other, thus allowing the transfer of torsional moment and preventing rotation of the beam part about the longitudinal axis of the beam.
  • the tongue part comprises a support surface onto which the beam part is supported.
  • the support surface receives the vertical load of the beam.
  • the side surfaces of the tongue part are partly vertical and partly inclined in such a way that the upper part of the tongue part is narrower than the lower part, whereby the width of the tongue part increases in the downward direction.
  • In the end plate of the beam part there is a slot, the shape of which corresponds to the shape of the sides of the tongue part, whereby the width of the slot increases in the downward direction.
  • the torsional moment transferring support surfaces of the tongue part and the abutment surfaces of the slot of the beam part are not supported to each other until the beam part has been lowered onto the tongue part. This way, additional play does not need to be formed in the connection for installation tolerances, but this play is provided by the downwardly widening structural design of the tongue part and the slot of the beam part.
  • connection has two vertical abutment surfaces located in the horizontal direction on opposite sides of the connection.
  • the surfaces must be located at a different height in the vertical direction. It is always more advantageous for the transfer of torsional moment the more there is height difference between the abutment surfaces in the vertical direction.
  • a vertical upper support surface for transferring the torsional moment.
  • a vertical lower support surface for transferring the torsional moment.
  • the horizontal distance between the symmetrical abutment surfaces of the upper part is smaller than the horizontal distance between the abutment surfaces of the lower part.
  • connection parts of the beam part are connected together by means of the same housing structure.
  • the housing of the beam part may be manufactured from a steel plate bent into a U-shape, which steel plate has been manufactured for example by rolling, which provides very small manufacturing tolerances.
  • a U-shaped housing is also from the manufacturing point of view the most economical solution, the like of which there is none in the prior art.
  • a clearance in the longitudinal direction of the beam as required for installation.
  • This clearance is needed because of the installation tolerances of the frame of the building.
  • This clearance for displacement in the longitudinal direction of the beam and at the same time an upwardly directed force may be locked by providing the tongue part with a vertical screw connection, the screw of which prevents a horizontal and vertical displacement of the beam part after installation.
  • Fig. 1-5 illustrate a connection arrangement according to one embodiment of the invention for connecting a vertical element, such as a column 2 or a wall element, and a beam 3 to each other.
  • the connection arrangement is a so-called hidden bracket in which the connection is disposed inside the beam 3 and the column 2.
