Detailed description of the invention

First the corbel 1 for supporting a first structural element 2 comprising concrete at a second structural element 3 comprising concrete and some variants and embodiment of the corbel will be described in greater detail.
The corbel 1 comprises a first support part 4 configured to be cast at least partly into concrete of the second structural element 3 comprising concrete.
In the embodiments illustrated in the figures the second structural element 3 comprising concrete is in the form of a reinforced concrete column.
In the embodiments illustrated in the figures the first structural component 2 comprising concrete is in the form of a steel-concrete composite beam having an outer steel shell structure 15 limiting an inner space 16 filled with or configured to be filled with concrete.
The corbel 1 comprises a second support part 5 that is fastened by bolts 6 to the first support part 4 so that a first face 7 of the first support part 4 abuts a second face 8 of the second support part 5 and on which second support part 5 the first structural element 2 is configured to be supported. The first support part is preferably, but not necessarily, provided with threaded holes (not shown in the figures) configured to receive and cooperate with the bolts 6 and the second support part 5 is preferably, but not necessarily, provided with through holes (not shown in the figures) configured to receive and be penetrated by the bolts 6 when the second support part 5 is fastened by the bolts 5 to the first support part. Said trough holes have preferably, but not necessarily, an inner diameter that is larger than the outer diameter of the bolts 6 so as to enable to adjust the fastening position of the second support part 5 with respect to the first support part 4 so at to in result adjust the relative position between the first structural element 2 comprising concrete and he second structural element 3 comprising concrete.
The corbel 1 comprises additionally preferably, but not necessarily, a stopper 20 configured to provides additional securing of the second structural element 3 comprising concrete on the corbel 1. The stopper 20 can for example have larger lateral extensions than the second support element 5. Such possible stopper 20 is preferably, but not necessarily, fastened by means of the bolts 6 at a free end of the corbel 1 so that the second support part 5 is arranged between the first support part 4 and the stopper when the second support part 5 and the stopper 20 is fastened by means of the bolts 6 to the first support part 4.
The first structural element 2 has preferably, but not necessarily, a recess 19 at the end of the first structural element 2 into which the second support part 2 of the corbel 1 is configured to penetrate so that the first structural element 2 is configured to be supported on the second support part 2 of the corbel 1 inside the recess 19. The recess 19 extends preferably, but not necessarily, from a lower edge (not marked with a reference numeral) of the end of the first structural element 2.
The corbel 1 comprises reinforcement rods 9 attached to the first support part 4 and extending from the first support part 4 on opposite sides of the second support part 5 beyond the second support part 5 so that the reinforcement rods 9 are configured to extend into concrete of the first structural element 2 comprising concrete. This provides for increased robustness in the connection between the first structural element 2 and the second structural element 3 because the reinforcement rods 9 connects the first structural component 2 directly to the corbel's 1 first support part 4 that is anchored by casting at least partly into concrete of the second structural component 3. The reinforcement rods 9 can also function as tensile reinforcement against disproportional collapse.

This makes the supporting of the first structural element 2 on the second support part 5 of the corbel 1 easier especially in cases where the first structural element 2 is in the form of a composite steel-concrete beam having an inner space 16 intended to be filled with concrete first after that the first structural element 2 has been supported on the second support part 5 of the corbel 1. In such cases the reinforcement rods 9 can be fastened to the sockets 10 after that the first structural element 2 has been supported on the second support part 5 of the corbel 1 by utilizing the inner space 16 of the first structural element 2 i.e. from the inner space 16 of the first structural element 2 and after that the reinforcement rods 9 have been fastened to the sockets 10, the inner space 16 of the first structural element 2 is at least partly filled with concrete resulting in that the reinforcement rods 9 will extend into the concrete of the first structural element 2. Additional reinforcement rods 11 are preferably, but not necessarily, fastened to the sockets 10 and extending in the opposite direction from sockets 10 in relation to the reinforcement rods 9. This provides for increased robustness. The optional additional reinforcement rods 11 are preferably, but not necessarily, provided with a headed end 12 configured to anchor the additional reinforcement rods 11 in concrete of the first structural element 2.
The reinforcement rods 9 can alternatively be fastened to the first support part 4 by welding.
The reinforcement rods 9 are preferably, but not necessarily, provided with a headed end 12 configured to anchor the reinforcement rods 9 in concrete of the first structural element 2.
The first support part 4 of the corbel 1 is preferably, but not necessarily, additionally provided with first anchoring studs 13 extending from the first support part 4 transversely in relation to the first face of the first support part 4.
The first support part 4 of the corbel 1 is preferably, but not necessarily, additionally provided with second anchoring studs 14 extending from the first support part 4 partly inclined and partly in parallel in relation to the first face 7 of the first support part 4.
