Abstract

Precast concrete column (1) for the support of structural modular floor, preferably dry assembled, comprising in its upper part a capital for the support (2) of beams (3), having the support capital (2) a square or quadrangular plan in such a way that four sides (21, 22, 23, 24) are defined for the support of the beams (3), in which each of the sides (21, 22, 23, 24) comprises concave recesses (4) of sides parallel to the axis of the beams (3) that define convex protrusions (5) which sides comprise bearing surfaces (6) such that when laying a beam (3), which ends are complementary to said recesses (4), the bearing forces have directions contained in a plane (41, 42, 43, 44) perpendicular to the axis of the beam (3), having said directions a horizontal component. The invention also refers to a beam complementary to this column and to slab segments, as well as to a structure provided with said columns, said beams and optionally also said slab segments.

Claims

1. Precast concrete column (1) for the support of structural modular floor, preferably dry assembled, comprising on its upper part a capital for the support (2) of beams (3), having the support capital (2) a square or quadrangular plan in such a way that four sides (21, 22, 23, 24) are defined for the support of the beams (3), wherein each of the sides (21, 22, 23, 24) comprises concave recesses (4) of sides parallel to the axis of the beams (3) that define convex protrusions (5) which sides comprise bearing surfaces (6) such that when laying a beam (3), which ends are complementary to said recesses (4), the bearing forces have directions contained in a plane (41, 42, 43, 44) that is perpendicular to the axis of the beam (3), said directions having a horizontal component.

2. Column according to claim 1, in which the concave recesses (4) are triangular or trapezoidal.

3. Column according to claim 1, in which the support capital includes passing through duct segments (11) in such a way that they allow threading the post-tensioning tendons.

4. Column according to claim 1, comprising at least two recesses (4).

5. Column according to claim 1, in which all four sides (21, 22, 23, 24) for the support of beams (3) comprise a protruding flap (14) in its bottom side intended to contain the grouting of the joints between the beams and the column.

10. Structure (50) composed by at least two columns (1) according to claim 1, and at least one beam (3) made of prestressed concrete for modular structural floor, preferably dry assembled, in such a way that four sides (31, 32, 33, 34) are defined, two of them being end sides (31, 33) for bearing the columns (1), wherein each of the end sides (31, 33) comprises convex recesses (7) of sides parallel to the axis of the beam that comprise bearing surfaces (8) such that, when laying the beam (3) on the bearing capital (2) of a column (1) provided with protrusions (5) complementary to said recesses (7), the bearing forces have directions contained in a plane (41, 42, 43, 44) perpendicular to the axis of the beam (3), having said directions a horizontal component.

11. Structure according to claim 10, comprising slab segments (12) provided with convex recesses (13) for support over the long sides (32, 34) of the beams.

12. Structure according to claim 11 in which the slab segments (12) include passing through duct segments (11) in such a way that they allow the threading of the post-tensioning tendons.

13. Structure according to claim 11 in which the bottom sides of the slab segments (12) comprise protruding flaps (14) intended to contain the grouting of the joints between the slab segments or with the beams parallel to them.

14. Structure according to claim 10 which includes on site threading of post-tensioning tendons, and their subsequent tensioning, anchoring, and injecting of the ducts.

6. Rectangular or quadrangular plan precast wide beam (3) made of prestressed concrete for modular structural floor, preferably dry assembled, in such a way that four sides (31, 32, 33, 34) are defined, two of them being end sides (31, 33) for bearing the columns (1), wherein each of the end sides (31, 33) comprises convex recesses (7) of sides parallel to the axis of the beam that comprise bearing surfaces (8) such that, when laying the beam (3) on the bearing capital (2) of a column (1) provided with protrusions (5) complementary to said recesses (7), the bearing forces have directions contained in a plane (41, 42, 43, 44) perpendicular to the axis of the beam (3), having said directions a horizontal component.

7. Beam (3) according to claim 6, in which at least one of the long sides (32, 34) comprises concave recesses (9) of sides parallel to the axis of the slab segments (12) that comprise bearing surfaces (10) such that, when laying on the beam (3) the slab segments (12), which ends are complementary to said recesses (9), the bearing forces have directions contained in a plane (41, 43) perpendicular to the axis of the slab segments (12), said directions having a horizontal component.

8. Beam according to claim 6 that includes passing through duct segments (11) in such a way that they allow the threading of the post-tensioning tendons.

9. Beam according to claim 6 in which one or two of its long side(s) comprise in its (their) bottom side a protruding flap (14) intended to contain the grouting of the joints between the slab segments and the beam.

15. Precast concrete column (101) for the support of structural modular floor, preferably dry assembled, comprising on its upper part, a capital (102) for the support of beams (103), having the support capital (102) a square or quadrangular plan in such a way that four sides (121, 122, 123, 124) of support of the beams (103) are defined, wherein each of the sides (121, 122, 123, 124) includes a rigid protruding flap (105) and is joined to the bottom side of the capital (102) and rigid rails (104) flat and parallel to the axis of the beam (103) that is supported on that side, which end comprises rigid flat plates (107) that fit in the rails (104) of the capital (102).
