Definitions

  • the invention relates to a method for forming a connecting structure between a pillar and beam, in which method multi-storey reinforced concrete pillars or multi-storey composite pillars and single-span beams are prefabricated and transported to the construction site, the pillars are mounted in place, and the beams and pillars connected at the construction site to form a connection.
  • the invention further relates to a connecting structure between a pillar and beam.
  • framework systems are continuously developed that differ from each other in the dimensions of components, materials, prefabhcation degree, mounting manner, load transmission manner, and various other matters.
  • the invention relates to a framework system having as load-bearing structures pillars, beams, and slabs.
  • Such frameworks may be constructed entirely at the construction site, constructed entirely from prefabricated elements or by using composite structures, whereby cast-in-place structures, that is, structures obtained by concreting at the construction site, are connected to prefabricated elements that also serve as moulds.
  • On-site casting generally means slow moulding work, reinforcement work, lots of supporting work, and other corresponding work phases, which means that a completely cast-in-place structure is today rare owing to its expensiveness.
  • Pillars are vertical structures to which primary horizontal structures, or beams, supporting secondary horizontal structures, or slabs, are supported.
  • the pillars may be of different lengths, as high as one storey, that is, single-storey pillars, or as high as several storeys, that is, multi-storey pillars.
  • the beams may also be of different lengths, in other words, single-span beams that extend to adjacent pillars at both ends or continuous beams that extend over several pillars.
  • a double-span beam extends from one pillar over an adjacent pillar to a third one.
  • single-span beams are generally used, and they support themselves to consoles in the pillars and are, thus, disposed between the pillars.
  • An advantage of the multi-storey pillars is that the number of pillars is small and there are no extension connectors.
  • their disadvantages are the consoles that cause extra costs and also the fact that static dimensioning of multi-storey pillars is arduous.
  • An advantage of the single-storey pillars is that there are no consoles and static dimensioning is simple. Their disadvantages are in turn the extension connectors of the pillars and the large number of pillars.
  • An advantage of a continuous beam is that its structure is lower and the fact that less beams are required. Another advantage is a good dynamic damping capacity of the structure. A disadvantage is in turn the fact that static dimensioning is arduous and also that a continuous beam requires reinforcements at the pillar.
  • An advantage of a single-span beam is that static dimensioning is simple and that no reinforcements are required at the pillar.
  • a disadvantage is that the beam is higher and the number of beams is high.
  • a structure formed by a single-span beam also has a poor damping capacity.
  • extension connectors of pillars are generally bolts and pillar shoes or steel plates.
  • extension connectors When using extension connectors, the amount of steel in the pillar increases, which adds to the costs.
  • the consoles in the pillar are either concrete consoles protruding from the pillar or steel consoles protruding from the pillar that are fas- tened after casting.
  • openings need to be made in the mould of the pillar, and the console protruding from the pillar needs to be moulded separately. This is slow and, therefore, also expensive.
  • steel consoles no holes need necessarily be made in the mould, but the amount of steel in the pillar increases, thus increasing the costs of the pillar.
  • consoles also affects the strain of the pillars. When a support reaction of a beam arrives at a console protruding from a pillar, its point of action is outside the cross-section of the pillar.
  • This eccentricity in other words, the distance between the point of action of the load and the centre of gravity of the pillar, causes a bending moment in the pillar, which needs to be taken into consideration in the static dimensioning of the pillar.
  • the pillar has to endure this bending moment without buckling, for example.
  • the bending moment increases the strain on the pillar and, thus, increases the cross-section and/or amount of steel in the pillar. This, in turn, increases the costs of the pillar.
  • Many console solutions of pillars are also so high that they often extend below the bottom surface of the beam. This is an architecturally poor solution and also complicates piping and partition wall work in the building.
  • Static dimensioning of a multi-storey pillar is somewhat more arduous than the dimensioning of a single-storey pillar. This is due to the increase in the number of load alternatives and a more complex operational model of the pillar.
  • a hinge-supported single-span beam is able to turn freely when bending on a support. This leads to needing a sufficiently rigid cross- section for the beam so that the bending in the middle of the beam does not become too large for the use of the building. This is why single-span beams are high.
  • An increase in the height of the beam affects not only material consumption and increases the weight of the structure, but also increases the total building height and the space to be heated.
  • a high beam extends below the floor and impedes piping and partition wall work and other mounting work in the building. All these add to the costs of the building.
  • beams extending below the floor impede later alteration work in the building, thus reducing its adaptability to change.
  • the damping capacity of a structure refers to the ability of the structure to absorb vibration energy. If the damping capacity of a structure is low, the movements of the structural parts may during vibration become stronger in the building when the frequency of the vibration is in range with the frequency of the structure. In such a case, the structures may be damaged or collapse.
  • the damping capacity of a structure is significant when building in an area where tremors and vibration may take place.
  • a continuous beam generally needs reinforcements at the pillar line so that loads from the pillar above can be transmitted to the pillars below through the beam. This usually means additional steel parts in the beam. These increase the cost of the beam. Additional steel parts also cause local stress centres in the pillars which, therefore, need additional reinforcing fittings, for instance, to prevent splitting.
  • Static dimensioning of single-span beams is somewhat simpler than that of continuous beams. This is due to the fact that single-span beams are generally designed hinge-supported at their ends.
  • console solution discloses in Finnish patent application No. 20060075, in which a concrete console mounted later on the pillar is used.
  • the drawbacks of this solution are steel parts in the console that add to the cost of the pillar.
  • the load coming to the console is also far from the centre of gravity of the pillar and, thus, adds to the loads coming to the pillar. This results in an increase in the cross-section and cost of the pillar.
  • the solution is also only suitable for use with hinge-supported single-span beams.
  • Continuous beams are made either very long or else by connecting shorter beams to each other with bolted joints, for instance, at the construction site. Extensions are slow to make at the site and require exact manufacturing and mounting tolerances. A connecting joint often also remains visible as an aesthetic flaw and causes a special point for fire protection. A connection may also be done at the site by welding, which is slow and expensive and requires good quality assurance. Continuous structures are also made by on-site casting, whereby the work is very slow with many work phases including moulding, reinforcing, supporting, casting, and the like.
  • the method of the invention is characterised in that the reinforcing steel fittings (6) are arranged to extend into a hole/notch at the end of the beam and to support on its rim.
  • the connecting structure of the invention is, in turn, characterised in that the reinforcing steel fittings (6) are arranged to extend into a hole/notch at the end of the beam and to support to its rim.
  • the invention provides a structure made of a multistorey pillar without consoles and a continuous beam made of single-span beams, and a method for forming it.
  • the invention has the advantages of a multi-storey pillar without the drawbacks caused by the consoles and the advantages of a continuous beam without reinforcements at the pillars.
  • the invention provides the advantage that the number of pillars remains low and there are no extensions and consoles.
  • the structure of the invention is also low. There are only a few beams at the site, and the damping capacity of the structure is good.
  • the solution of the invention also does not require reinforcements at the pillar.
  • Figure 1 is a general perspective view of a possible pillar of a connection of the invention
  • Figure 2 is a general side view of the basic principle of a connecting structure of the invention
  • Figures 3 to 4 are general perspective views of a connecting structure of the invention with several different solutions for supporting a beam

  • Figures 6 to 8 are general perspective views of various embodiments of a connecting structure of the invention.
  • the invention relates to a method for forming a connecting structure between a pillar and beam, and to a connecting structure.
  • multi-storey reinforced concrete pillars or multi- storey composite pillars and single-span beams are prefabricated and transported to a construction site, the pillars are mounted in place, and the beams and pillars are connected to each other at the construction site to form a connection.
  • the invention is a combination of a multi-storey pillar without consoles and a continuous beam made of single-span beams. This solution provides the advantages of a multi-storey pillar without the drawbacks caused by the consoles and the advantages of a continuous beam without reinforcements at the pillars.
  • FIG. 1 is a general view of an embodiment of the above-mentioned pillars.
  • the pillar is marked with reference number 1.
  • the connecting point of the beams is marked with reference number 2.
  • the reinforcement and/or other steel parts visible at the connecting point are marked with reference number 3.
  • the reinforcement and/or other steel parts of the pillar are completely visible, in other words, the connecting point only has the reinforcement and/or other steel parts.
  • the connecting point In large pillars, there may be a concrete neck in the middle of the pillar.
  • the connecting points 2 of the pillar and beam have not been concreted when they are brought to the construction site.
  • Single-span beams 4 with a connector 5 at both ends are also brought to the construction site.
  • the connector 5 may be made of a metal material, such as a steel material.
  • the beam may be a reinforced concrete composite beam.
  • the figures show the steel part of the beam. The basic principle of the connecting structure of the invention is shown in Figure 2.
  • the method comprises steps for prefabricating multi-storey reinforced concrete pillars or multi-storey composite pillars 1 in such a manner that there is only reinforcement 3 at the connecting point 2 of the beam and pillar.
  • Single- span beams 4 are prefabricated in such a manner that both ends of the beams have a connector 5.
  • the beams are mounted and supported between stationary pillars 1 in such a manner that the connectors 5 at the ends of the beams or their action extend inside the pillar 1 at the connecting point 2 of the beam and pillar.
  • Reinforcing steel fittings 6 extending through the pillar 1 at the con- necting point 2 are mounted in the area of the beam end.
  • the beam 4 and connecting point 2 are concreted together.
  • the beams 4 are mounted between the pillars 1 at a correct height on a support in such a manner that the ends of the beams are in a way embedded into the pillar 1.
  • the support of the beam 4 may be a part 7 fastened to the pillar 1 and later removed, as shown in Figure 3, for example.
  • the beam may also be supported from below by means of support members 8, as shown in Figure 4.
  • the beam 4 is only supported at its ends.
  • Reinforcing steel fittings 6 extending through the pillar at the connecting point are mounted at the connecting point of the pillar and beam to provide a connection.
  • the above-mentioned reinforcing steel fittings 6 extending through the beam and parallel thereto are separate elements to be mounted on site, for instance deformed reinforcing steel bars.
  • the reinforcing steel fittings 6 may extend through a hole or notch at the end of the beam and support on its rim as shown in Figures 6 to 8, for instance.
  • the holes or notches may either be in the connector 5 or in a flange at the end of the beam or in both as shown in the figures.
  • the reinforcing steel fittings 6 may also extend to the side of the beam 4 as shown in Figure 7, or inside the beam as shown in Figure 8. At this stage, it is also possible to mount slabs 9 on the beam as shown in Figures 5 and 6.
  • the reinforcing steel fittings 6 may preferably be bound to the reinforcements and/or structures of the pillar 1 and beam 4.
  • the beam 4 is concreted at the same time as the slabs 9, in other words, the steel part of the beam 4 is also filled with concrete and, at the same time, the connecting point 2 is concreted. After the concrete is hardened, the mounting supports of the beam may be removed. After this, the reinforcing steel fittings 6 extending through the pillar at the end of the beam serve as extension steel fittings and form continuous structures of the beams 4. The above-mentioned reinforcing steel fittings mounted on site do not require any special skills or conditions.
  • connection between the pillar 1 and beam 4 remains completely hidden inside the concreting, so it is already fire protected by concrete and a separate protecting phase with special materials is not needed.
  • the connection is also invisible, so the visible structure is neat and clean and does not require covering.
  • the bottom surface of the beam is uniform along the entire length of the beam. It does not have a downward-opening slot for a console, for instance, which would be visible from a finished structure as an irregularity.
