Definitions

  • the invention relates to a strip-shaped composite element for a steel-concrete composite according to the preamble of claim 1.
  • Composite ceilings combine different materials in their load-bearing capacity. Through the Coupling different materials, their advantages are not only activated additively, but can achieve above-average quality increases with optimal utilization achieve.
  • WO 89/00223 describes a composite ceiling consisting of Steel beams, trapezoidal sheets, composite elements and structural concrete, known. From composite elements made of strip-shaped trapezoidal sheets serve to accommodate Lateral forces that occur in the composite floor when there are essentially vertical forces act on the composite ceiling from the outside. The absorption of these transverse forces is only then possible if the building concrete completely encloses the composite elements and if a good adhesive bond between the composite elements and the building concrete consists.
  • the composite element known from WO 89/00223 has large-area, Roof surfaces and large leg surfaces that run parallel to the contact surfaces on, which are arranged at an angle to the support surfaces or the roof surfaces are.
  • the invention has for its object to provide a composite element with which the shear forces arising from the composite ceiling, which are essentially perpendicular to the The forces acting on the composite ceiling are absorbed well and safely can be.
  • the composite element should be designed so that even "dry” applied concrete securely encloses the composite element so that it is a good one Adhesive connection between the composite element and the building concrete is created.
  • the construction concrete due to the passage openings according to the invention in at least one of the exposed surfaces of the sheet completely enclose it and better to the surface of the ceiling reach. In this way, a safe static friction between the building concrete and reached the sheet and prevented the formation of air pockets.
  • the leg surfaces around are somewhat larger than the roof areas. So that the building concrete is well under the Roof surfaces and the leg surfaces can expediently be the exposed surfaces formed by the leg surfaces.
  • the composite element In order to have a sufficiently high tensile strength for the absorption of the transverse forces to be able to retain the composite element is preferably the total Cross-sectional area of the passage openings arranged in the leg surfaces, at most 75% of the total thigh area.
  • the tensile forces acting on the composite element in the composite element Do not overload area of one of the two long sides, suitably corresponds in a parallel to the contact surfaces and perpendicular to the longitudinal extent of the sheet extending direction, one between an outer contour of the sheet and one Passage-extending, remaining width at least 0.05 to 0.3 times Overall width of the composite element.
  • the cross-sectional areas of the passage openings can be circular or of one circular shape may be different. Deviating from the circular shape means that the cross-sectional areas of the passage openings are, for example, square, rectangular, oval, elliptical, etc. are formed.
  • the rectangular ones Through openings can also have the shape of narrow slots, for example and, starting from a support surface, over the entire length of the Extend leg surfaces up to a roof surface. It is also possible that in the Leg surface one or more slots are arranged that are opposite the length of the Leg surface are arranged at an angle. So that no notch effects in the Corners of the passage openings can occur, for example, with the corners with a radius.
  • the shape and size of the cross-sectional area of the passage openings and the The number of openings depends very much on the grain size of the building concrete and the wetness with which the building concrete on the ceiling formed by the trapezoidal sheets is applied.
  • composite elements are used, for example, in the area of Leg surfaces and / or the roof surface over only one, for example larger Have passage opening. This "large" passage opening can be from the building concrete be enforced very well. If, for example, building concrete is used, whose pebbles have a small grain and the application of this building concrete on the blanket "very wet", it is sufficient if the individual Passages in the composite elements have a small cross-sectional area.
  • the angle between the Contact surface and the leg surface 60 ° to 90 ° is preferably the angle between the Contact surface and the leg surface 60 ° to 90 °. Take at an angle of 90 ° mainly the contact surfaces and the roof surfaces on the composite element acting tensile stresses. But if the thigh surfaces opposite the Support surfaces and the roof surfaces, for example at an angle of 60 ° are arranged, so the leg surfaces next to the bearing surfaces and the Roof areas for absorbing tensile stresses. Especially when forces For example, it acts constantly on the composite ceiling at an angle possible to form the composite elements in such a way that two adjacent to each other Leg surfaces opposite the bearing surfaces, or the roof surfaces below are arranged at different angles.
  • the wall thickness of the sheet mainly depends on the size of the Composite ceiling vertically acting forces that with the help of the composite elements in the Composite ceiling can be initiated.
  • the wall thickness of the sheet is advantageously 0.75mm to 3mm.
  • Corrosion of the composite element can be prevented by the sheet is coated with a zinc layer.
  • the composite element has, for example Overall width from 30 mm to 300 mm.
  • the invention is based on a drawing, the composite element according to the invention reproduces, explained in more detail.
  • a double T-beam 2 is shown, on which part of a ceiling 9 is shown, which is formed by several trapezoidal sheets. There is only one in the drawing Trapezoidal sheet shown.
  • a composite element is arranged just above the carrier 2, which consists of a strip and Trapezoidal sheet 1 is made.
  • the leg surfaces 5 of the composite element are longer formed so that the roof surfaces of the composite element from the roof surfaces of the trapezoidal sheet forming part of the ceiling are spaced.
  • the in relation to one Longitude of the composite element parallel length L1 of Contact surfaces 3 of the composite element are shorter than the length L2 of the roof surfaces 4 of the composite element and shorter than the contact surfaces of the trapezoidal sheet.
  • the Roof surfaces 4 can be made longer than the contact surfaces of the Composite element and the trapezoidal sheet. This is the case, for example, if the contact surfaces of the composite element only with every second contact surface of the Interact trapezoidal sheets.
  • the attachment of the ceiling 9 and the composite element on the carrier 2 serve for example, not shown, nail-shaped fasteners 6, 7 which Push through the contact surfaces of the sheet 1 and the ceiling 9 and in the double-T beam are driven in.
  • Driving these nail-shaped fasteners into the Double-T beam 2 serves, for example, a gas, pressure or also not shown powder-operated setting tool.
  • a connection between the composite element and the ceiling can also be welded or with the help of a screw connection can be achieved.
  • the leg surfaces 5 of the composite element run with respect to the contact surfaces 3 and the roof surfaces 4 at an angle W of 60 ° to 90 °.
  • openings 10, 11, 12, 13, 14, 15, 16, 17 arranged, which differ from one another by their cross-sectional shape and size differentiate.
  • the cross-sectional areas of these passage openings 10, 11, 12, 13, 14, 15, 16, 17 are, for example, circular, square, rectangular, oval, elliptical, etc. and instead of only one passage opening 10, 11, 12, 13, 14, 15, 16, 17 in the leg surface 5 or the roof area 4, two or more passage openings 10, 11, 12, 13, 14, 15, 16, 17 be present.
  • the cross-sectional areas of the passage openings 10, 11, 12, 13, 14, 15, 16, 17 can be uniform in shape and size per composite element; uniformly in shape, but different in size; different in shape and size or be different in shape and uniform in size.
  • the total width B1 of the Sheet 1 can be 30 mm to 300 mm.
  • the direction of the sheet metal 1 corresponds to that between an outer contour 18 of the sheet 1 and a passage opening 10, 11, 12, 13, 14, 15 remaining width B2 at least 0.05 to 0.3 times the total width B1 of the composite element.
