Definitions
- the present invention relates to steel components that can replace predetermined areas of intended for load bearing reinforced concrete components, in particular reinforced concrete beams, and which can be designed structurally less tight without loss of load-bearing capacity to create space for technical installation elements such as lines, cables and channels .
- the aim of the general prior art is not to have to arrange technical installation elements below a supporting structure but within the construction level in order not to reduce the ceiling height of a building for technical installation at the same floor height or not to have to increase the floor height at the same clearance height .
- load-bearing bars must be provided with openings through which installation elements can be guided.
- the load-bearing capacity of webs is, however, reduced by the introduction of openings that are too close together. For this reason, openings must be spaced so far that the load-bearing capacity defined for the building in question is not undershot.
- the published patent application DE 198 60 340 A1 already deals with the problem of the high installation density that is to be made possible within the construction level. It proposes a composite girder for structures with a web for absorbing transverse forces and with web openings for the passage of installation elements, the web openings being formed in a predetermined area of the carrier in which comparatively low transverse forces act on the overall carrier. Such an area is regularly arranged centrally within the entire girder in uniformly loaded single-span girders, since the transverse forces within a girder decrease from its ends to the center, while the load from the global moment acts most strongly in the middle. In the case of multi-span girders, especially those with different spans or uneven loads, other conditions may prevail,
- the composite beam proposed in DE 198 60 340 A1 has the disadvantage that the predetermined area in which relatively low transverse forces act is surrounded by areas of the composite beam in which larger transverse forces act.
- Such a composite beam typically runs over the entire area to be underpinned.
- the entire composite beam i.e. both the areas that are exposed to high transverse forces and the area provided with web openings, are made of steel, with a one-piece compression belt running through the entire length of the beam above the web openings, with the disadvantage of increased amounts of steel to be installed and correspondingly high costs.
- the task is therefore to provide the function of the named composite girder of the prior art and at the same time to significantly reduce the amount of steel to be built.
- a steel insert is proposed for buildings to replace predetermined areas of reinforced concrete components intended for load bearing, in particular reinforced concrete beams, which has a recess support having two longitudinally spaced connection surfaces with one of the connection surfaces different upper, lower, front and rear sides as well as one or more carrier openings of the recess carrier which are provided for the passage of installation elements and lead from the front to the rear and whose distance from the respective adjacent connection surface is less than their respective height between the top and bottom.
- the connection surfaces are accordingly arranged on the end faces of such a bar, while the ceiling to be underpinned directly or indirectly rests on the upper side.
- the respective sides are designed flat.
- connection surfaces of the recess support are not to be set equal to the ends defining the length of the steel component. Rather, the term connection surface denotes those surfaces of the recess support that are provided for the length of the concrete-free area of the supporting structure made of reinforced concrete component and To limit steel insert by the concrete of the reinforced concrete component is guided in the longitudinal direction of the recess beam up to these surfaces.
- connection surface is initially considered to be the connection surface, with the same size being the surface which is closer to the carrier opening.
- connection means which protrude in the longitudinal direction beyond these surfaces or their planes or are arranged on them can be present as parts of the steel component, which are encased by concrete for connection purposes.
- the distance between a carrier opening and an adjacent connection surface is defined for each of the connection surfaces as the shortest distance between the respective connection surface and the closest carrier opening, the height of which is the largest dimension between the top and bottom of the recess carrier parallel to the shortest connection path between its upper and bottom is determined.
- the goal of saving steel as a carrier material by means of the proposed steel insert can be achieved more easily in that at least one carrier opening is delimited at its lower edge by one of the broad sides of a steel strip.
- the steel strip has a cross section that is wider than it is high, so that a distinction can be made between broad sides, which extend along the width of the cross section in the longitudinal direction of the steel strip, and narrow sides which extend analogously along the height of the cross section.
- broadside is also used for other components or elements and thus refers analogously to the fact that their cross-section is wider than it is high.
- the steel component is preferably positioned in such a way that the steel band acts as a tension band when there is a positive moment.
- a positioning is also possible in which the steel belt takes on the function of a compression belt, if at all with a comparatively small negative moment.
- the recess carrier of the steel component may be formed not only with one but with more than one carrier opening, the distance between adjacent carrier openings being less than the height of the higher carrier opening. As a rule, all carrier openings will have the same height.
- a carrier opening can advantageously be divided into separate sections by one or more stiffeners extending between the top and bottom, the extent of which extends in the longitudinal direction of the recess carrier is less than the height of the relevant carrier opening.
- stiffeners extending between the top and bottom, the extent of which extends in the longitudinal direction of the recess carrier is less than the height of the relevant carrier opening.
- steel sheets will prove their worth here as stiffeners, the broad sides of which are arranged orthogonally to the longitudinal alignment of the recess support.
- the steel component has a profile intended for sheathing with concrete for transmission of transverse forces on the top of the recess support.
- a profile is preferably designed as a bar, as a T-profile or as a double-T-profile and is arranged parallel to the longitudinal alignment of the recess carrier.
- the recess support has a support plate to which the top of the recess support is associated, which protrudes from under the profile and for the support of the structure (A), for example a floor ceiling, on the one not covered by the profile Areas is provided.
- the profile for transverse force transmission has holes which are provided for penetration with reinforcing bars transversely to the longitudinal alignment of the recess support.
- the concrete is brought up to the top of the recess support or up to the support plate.
- bolts preferably headed bolt dowels, protrude from the profile for shear force transmission parallel to the shortest connecting distance between the top and bottom of the recess support, which are also provided for encasing with concrete.
- a preferred embodiment of the steel insert has on one or both sides an extension of the recess support on the underside in the longitudinal direction.
- Such an extension is advantageously designed as a continuation of the steel strip beyond the plane of the respective connection surface. It is preferably provided that the concrete is guided both up to the end face of the recess carrier and up to the end face of the continuation of the steel strip.
- the face of the recess carrier is considered to be the connection surface, since it is larger than the face of the continuation of the steel strip.
- the steel insert has a shear reinforcement provided for sheathing with concrete for the transmission of transverse forces on at least one connection surface, the broad sides of which are aligned parallel to the longitudinal direction of the recess support and to the shortest connecting distance between its top and bottom.
- Anchoring the shear reinforcement in concrete can be advantageous are reinforced by the fact that it is designed as a thrust plate with transversely protruding bolts arranged on one or both sides, preferably with welded-on head bolt dowels.
- the profile and the shear reinforcement are rigidly connected to one another, for example by welding.
- the parts connected in this way preferably comprise the recess carrier, with the exception of the underside, in a frame-like manner.
- connection of reinforced concrete to the connection surfaces can advantageously take place in that on the connection surfaces, parallel to the longitudinal alignment of the recess carrier, reinforcing rod sections are arranged to connect the steel reinforcement of the reinforced concrete component, for example by means of screw joint or lap joint.
- Bolts provided for sheathing with concrete preferably head bolt dowels, can, if appropriately positioned, contribute advantageously to better embedding of the steel component in reinforced concrete, especially if they protrude from a connection surface parallel to the longitudinal orientation of the recess support or from the top of the recess support.
- the steel component forms a supporting structure by completely or partially replacing the reinforced concrete in an area in which the effect of relatively low transverse forces is preferably provided.
- the reinforced concrete is brought up to the connection surfaces in the longitudinal direction of the recess support.
- the reinforced concrete runs above and / or below the steel insert in the longitudinal direction of the recess carrier over the entire length to be underpinned.
- the steel component can be arranged to form the supporting structure in various positions with respect to the reinforced concrete component. In this way, the top and / or the bottom of the recess support can end flush with the reinforced concrete component. Knows If the profile has a support plate, this can be flush with the reinforced concrete component. If an area of the reinforced concrete component is only partially replaced, the underside of the recess support can rest on a reduced cross-section of the reinforced concrete component, it being advantageous if the reinforcement of the reinforced concrete is continuously arranged below the steel component.
- the steel component has an extension of the recess support on the underside in the longitudinal direction thereof, which is preferably designed as a continuation of the steel strip beyond the plane of a connection surface, the continuation can be encased with concrete when the underside rests on a reduced cross-section. It is also possible, however, for the underside of the recess support including the underside of the continuation to be kept free of concrete and for the concrete to be guided up to the front sides of the continuation and the connection surfaces of the steel component.
- Fig. 1 shows the steel component (1) in a front view.
- the recess carrier (5) here has a steel band (12) on its underside (7), which is guided as an extension (20) beyond the planes of the connection surfaces (4).
- On the top (6) of the recess support (5) is a bar-shaped profile (16) for the transmission of transverse forces, which has holes (18) which are provided for penetration with reinforcing rods (Fig. 3rd point 26).
- Reinforcing bar sections (23) are welded onto the projections (20) and can be connected to the reinforcement of the reinforced concrete component (Fig. 3, item 3) by means of a screw joint, shown as a thickening of the reinforcing bar sections (23).
- Shear reinforcements (21) designed as thrust plates are arranged on the connection surfaces (4), the broad sides (22) of which are parallel to the longitudinal direction of the recess support (5) and to the shortest connecting path between the top (6) and the bottom (7) are aligned, here so parallel to the front (8) or back (9) of the recess support (5), and are welded to the profile (16) so that the recess support (5) with the exception of its underside (7) comprises a frame is.
- Bolts (19), here designed as headed bolt dowels, protrude from the shear reinforcements (21) from the image plane in the direction of the viewer. They are arranged on both sides transversely to the shear reinforcements (21) and welded to them.
- the recess carrier (5) here has a carrier opening (10) which is divided into separate sections (14) by stiffeners (15) and has a height (h) between the top (6) and underside (7) of the recess carrier (5) which is greater than the distance between the carrier opening (10) and the connection surfaces (4).
- the carrier opening (10) is delimited at its lower edge (11) by one of the broad sides (13) of the steel strip (12).
- Fig. 2 shows the supporting structure (24) made of the steel component (1) and the here beam-shaped reinforced concrete component (3) under the ceiling of a structure (A) obliquely from below.
- the reinforced concrete is completely replaced by the steel component (1), which is flush with the reinforced concrete component (3) at the top and bottom.
- the steel band (12) of the steel component (1) is exposed to tensile forces resulting from the positive global moment in the area (2) of low transverse forces and functions as a tension band.
- the carrier opening (10) is divided into three sections (14) by two stiffeners (15).
- the concrete of the reinforced concrete component (3) is brought up to the connection surfaces (4) and the end faces of the extensions (20) of the steel strip (12), the lower broad side (13) of which can be seen from below.
- the carrier opening (10) with its sections (14) is so large here that there is a lot of space available for the installation elements and at the same time comparatively little steel is built in, since the distance between the carrier opening (10) to the connection surfaces (4) in relation to the height (h) of the carrier opening (10) is small.
- Fig. 3 shows the supporting structure (24) similar to FIG. 2 diagonally from below with the difference that the reinforced concrete component (3) and the ceiling of the structure (A) are shown partially transparent, so that the reinforcing bars (26) can be seen, which are parallel to the longitudinal alignment of the recess beam (5) over the Reinforcing bar sections (23) are connected to the steel component (1) and are guided transversely to the longitudinal alignment of the recess support (5) through the holes (18) of the profile (16), which is here bar-shaped and alone or in combination with the ceiling picks up local moments and forms the pressure belt for the global moment.
- Fig. 4 shows an embodiment of the supporting structure (24) below the ceiling of the building (A) obliquely from below, in which the reinforced concrete component (3) in the area (2) is only partially replaced by the steel component (1) and the reinforced concrete component (3 ) is designed continuously above the top (6) with a reduced cross-section (25).
- Fig. 5 shows an embodiment of the supporting structure (24) below the ceiling of the building (A) obliquely from below, in which the reinforced concrete component (3) in the area (2) is only partially replaced by the steel component (1) and the reinforced concrete component (3 ) is designed continuously below the bottom (7) with a reduced cross section (25).
- Fig. FIG. 6 shows part of the FIG. The embodiment shown in FIG. 5 without concrete, so that the continuous reinforcing bars (26) of the reinforced concrete component (FIG. 5, item 3) passing underneath the underside (7) are visible.
- Fig. 7 shows part of the steel component (1) in which the shear reinforcement (21) is designed as a shear lug.
