Description

[0001] This invention relates to a joint arrangement according to claim 1 for connecting a glued-laminated-timber horizontal brace and / or at least one glued-laminated-timber diagonal brace of a glued laminated timber frame to a frame part of the glued laminated timber frame for stabilizing the glued laminated timber frame. The invention also relates to a glued laminated timber frame of a building or a structure.

[0002] Traditionally, the stabilizing bracing of a glued laminated timber frame of a building is made of steel tension bars, whereby the tension bar is installed into a hole drilled through a glued laminated timber column or a glued laminated timber beam and anchored by a screw thread and a nut to a back surface of the timber structure. The joints of glued laminated timber structures may be achieved with many different techniques, and some of them are also suitable for worksite conditions and some of the joints are only suitable for factory conditions. Usually, the joints are different kinds of steel-constructed parts, plates, screws, nail plates, etc., that are fastened to the wood using various techniques. In the known joint solutions the problem is a low prefabrication level of the steel structures to be used, whereby on the worksite there are many structures and joints to be made on-site. Consequently, the joint solution is labour-intensive and often expensive and may not be automated. Document JPH08120790A discloses a joint arrangement comprising all the features of the preamble of claim 1.

[0003] It is an object of this invention to provide a glued laminated timber frame joint arrangement and a glued laminated timber frame by which the problems described above may be mitigated.

[0004] The object according to the invention is achieved by the joint arrangement according to claim 1 and by the glued laminated timber frame according to claim 6.

[0005] A joint arrangement according to the invention for connecting a horizontal brace made of glued laminated timber and / or a diagonal brace made of glued laminated timber to a frame part, such as a glued laminated timber column or glued laminated timber beam, of a glued laminated timber frame comprises a coupling part fastenable to the frame part, which coupling part comprises a front plate to be arranged against a front surface of the frame part, with sockets having an internal thread fastened to a rear surface of the front plate and thread bars arrangeable into holes extending through the frame part screwed into the sockets, a back plate to be arranged against a back surface of the frame part and having fastening holes through which the thread bars are insertable, and nuts to be screwed onto the thread bars for fastening the front plate and the back plate to the frame part. Further, the joint arrangement comprises a connecting part to be fastened to the front plate and comprising an end plate fastenable to a front surface of the front plate by fastening screws to be screwed into the sockets, and a connecting element fastened to the end plate, and a brace part for each diagonal brace and / or horizontal brace, which brace part is fastenable to an end of the diagonal brace and / or the horizontal brace and to the connecting element.

[0006] A glued laminated timber frame according to the invention comprises a frame part made of glued laminated timber, such as a glued laminated timber column or glued laminated timber beam, a horizontal brace made of glued laminated timber and / or one or two diagonal braces made of glued laminated timber. The horizontal brace and / or each diagonal brace are connected to the frame part with a joint arrangement according to the invention, a coupling part of which is fastened to the frame part and a brace part is fastened to an end of each diagonal brace and / or horizontal brace and to a connecting element of a connecting part.

[0007] The invention may provide significant advantages.

[0008] At present, the fabrication of glued laminated timber structures is automated, and very dimensionally accurate holes and grooves may be made in glued laminated timber by CNC machining tools. This also enables the prefabrication of the prefabricated glued laminated timber structure joint arrangements according to the invention, whereby the work to be done on the worksite may be allocated to industrial prefabrication. The work may be allocated to the factory and automated, providing cost savings.

[0009] Steel-constructed connecting parts may be used in the invention, which may be connected to the parts of the glued laminated timber frame by gluing for example with epoxy-based glues, whereby the solution requires warm factory conditions. Gluing methods may be applied in the solution according to the invention because by gluing, also high loads may be transferred, which are present in stabilizing structures of the frames of buildings. The solution requires the positioning of the joints to have high dimensional accuracy, which is only achieved in factory conditions by CNC machining tools.

[0010] The glued laminated timber structure as a material is non-homogeneous in terms of strength. This means that a glued laminated timber material withstands, in the direction of the wood grain, a compression force that is 5-10 times higher than in a direction that is perpendicular against the wood grain. This property is utilized in the joint arrangement and the glued laminated timber frame according to the invention, wherein the forces to be transferred are to be transferred in the direction of the wood grain or, in the transfer of a force in a direction that is transverse to the grain, a wider structure is used that is able to receive the same loading over a larger area. The strength of the joint is therefore dependent on the direction of the grain of the glued laminated timber, which is taken into account in the structure of the joint.

[0011] In the traditional glued laminated timber joint technique the braces of the stabilizing bracing are made of steel parts. In this invention the stabilizing bracing is implemented by horizontal and / or diagonal braces made of glued laminated timber that are connected to column parts fastened to glued laminated timber columns and being typically made of steel. The steel parts of the joint arrangement are sized in such a way that they may be installed into holes and grooves formed in the glued laminated timber column and in the glued laminated timber braces. The functioning of the stabilizing bracing is similar to the traditional concrete element frame, but the joint arrangements are designed entirely according to the requirements of the glued laminated timber frame, because the connecting parts fabricated in a concrete frame may not be used as such. In the traditional concrete frame technique, every brace may be fastened to concrete by a respective connecting part. The joints may be located adjacently and at a distance from each other. With wood, this technique is not advantageous, because the circulation of internal forces of the braces of the stabilizing bracing through wood introduces rather high internal forces into the joint and the transfer of those forces through the "weak" wood increases the connecting parts to a significant degree and is consequently very uneconomical. In concrete structures this circulation of forces through concrete is not a problem because of the higher strength of concrete.

[0012] In the solution according to the invention the traditional stabilizing bracing structure is implemented such that the horizontal and / or the diagonal braces of the stabilizing bracing are fastened at their ends to the same connecting part of a coupling part, which connecting part is outside of the joint disposed in the glued laminated timber column. The connecting part now transfers internal forces of the braces introduced to the node point of the stabilizing bracing via the steel structure of the joint. With the solution, also high forces can be transferred that do not circulate in the joint through the weak glued laminated timber. Only an external force to the brace system is transferred to the horizontal brace of the stabilizing bracing, whereby the forces introduced in the glued laminated timber may be minimized compared to the traditional bracing structure.

[0013] In the solution according to the invention, the joint within the glued laminated timber column transfers forces in two directions, for which forces the connecting parts have been designed in such a way that the best properties of glued laminated timber may be efficiently utilized. Due to the positioning of the horizontal and the diagonal braces of the stabilizing bracing outside the glued laminated timber column, two forces are exerted on the actual joint within the glued laminated timber column that are at an angle of 90 degrees against each other. A perpendicular compressive or tensile force to the surface of the glued laminated timber column is exerted on the joint from the direction of the diagonal braces. The second force is a shear force parallel to the surface of the glued laminated timber column that is transferred from the joint into the glued laminated timber column as a force parallel to the column. The magnitude of these two forces relative to each other varies according to the loading of the frame and the bracing structure.

[0014] From the bracing joint a shear force parallel to the surface of the glued laminated timber column is transferred via the screws of the column part to the internal thread sockets welded to the front plate embedded in the surface of the joint. The external surface of the internal thread socket transfers the force to the glued laminated timber as a compressive force parallel to the grain. In one embodiment of the invention, plate-shaped shear studs welded to the back surface of the front plate also transfer the shear force to the glued laminated timber, in case the load of the stabilizing bracing is high. The number of the shear studs is selected depending on how high the shear force is and whether the sockets are able to transfer the entire shear force. The shear studs are therefore not necessarily needed in all cases, but if needed, the sockets and the shear studs function together as a shear force transferring structure. In this invention, the internal thread sockets function as a structure transferring the tensile force to the back plate of the joint, and the external surface of the socket also transfers the shear force to the glued laminated timber column. Thereby the sockets participate in the transfer of two force components of different directions in the glued laminated timber, which makes the structure of the joint arrangement very beneficial.

[0015] A horizontal compressive force introduced from the bracing joint perpendicularly against the surface of the glued laminated timber column is transferred via the front plate of the coupling part to the glued laminated timber in a direction perpendicular against the grain. The front plate has a wide surface area, and the force may therefore be transferred through the glued laminated timber. If a tensile force is exerted on the same point from the stabilizing bracing, it is transferred via the fastening screws to the sockets and from there to the thread bars passing through the glued laminated timber column, and the force is anchored to the back plate arranged against the back surface of the glued laminated timber column, from where it is transferred to the glued laminated timber column as a compressive force. This way, the forces are transferred to the glued laminated timber column as a compressive force either to the front or to the back surface. The force may be transferred over a wide area, because it is now exerted in a direction perpendicular against the grain of the glued laminated timber column. Due to the weaker structure of wood, the force requires a wider surface area for transferring the force to the wood.

[0016] The brace part at an end of the horizontal and the diagonal brace may be fastened to the wood by means of a brace plate of the brace part to be arranged against the end of the brace. Straight reinforcing bars are fastened to the brace plate either by screws or by welding. The reinforcing bars are fastened by gluing into holes drilled in the brace. A tensile force of the brace is transferred from the reinforcing bars to the glued laminated timber as a compressive or tensile force exerted through its grain via the glued joint. In case the force is a compressive force, the force is transferred directly from the brace plate at the end of the brace to the wood. That is, in each case, the transfer of the force takes place parallel to the grain of the glued laminated timber. The same brace part may transfer forces in two directions, but it is achieved by different parts of the brace part.

[0017] Between the glued laminated timber column and the braces there is a connecting part that joins the glued laminated timber column and the diagonal braces of the stabilizing bracing to each other. The connecting part may be made of a steel plate and shaped according to the requirements of the positions and angles of the glued laminated timber column and the braces for each separate case. The connecting part may therefore not be a standard product in terms of dimensions, but it enables the parts connected to the glued laminated timber column and to an end of the brace to be made with a standard structure and productized. The connecting part also ties the diagonal braces of the bracing to each other and fastens them to the glued laminated timber column. This part circulates the axial forces of the diagonal braces directly forward in the stabilizing bracing and only those forces are transferred to the glued laminated timber column which remain in this node of the bracing structure as a horizontal force. With the connecting part the excessive eccentric forces within the joint can thus be removed from the glued laminated timber column, which forces would otherwise circulate through the "weak" glued laminated timber.

[0018] By the joint arrangement according to the invention and by its design and positioning the external forces introduced to the stabilizing bracing as well as the internal forces transferred in the stabilizing bracing may be transferred via such structures that are able to best transfer it in terms of the material properties of the structure. Therefore, in the area of the joint, as small amount of forces as possible are circulated through the glued laminated timber, and the forces are distributed in directions parallel to the grain and perpendicular against the grain, because in these cases there is a 10-fold difference in the strength of the wood in favour of the wood grain direction.

[0019] The invention will now be described in more detail by way of examples with reference to the accompanying drawings, in which Fig. 1 illustrates a side view of a joint arrangement according to one embodiment of the invention that is fastened to a glued laminated timber column and to a glued-laminated-timber horizontal brace and to glued-laminated-timber diagonal braces of a glued laminated timber frame, Fig. 2 illustrates the joint arrangement according to Fig. 1 as seen from above and as a sectional view.

In the known glued laminated timber frames a stabilizing bracing is connected to adjacent frame parts, which bracing comprises a horizontal brace made of steel connected to the frame parts, and two crossed diagonal steel braces (tension bars) that are connected at their ends to the frame parts. In the glued laminated timber frame according to the invention, the stabilizing structure may comprise only one glued-laminated-timber diagonal brace 2, 4, because the glued-laminated-timber diagonal brace is able to receive both tension and compression.
