Definitions

• the invention relates to a carrier arrangement with a substantially rectilinear carrier arranged between two bearings, which extends along a longitudinal direction and is composed of at least three longitudinally successive segments connected to one another via two top plate joints, namely a middle segment and two outer segments, wherein Bearings are hampered by the displacement in the longitudinal direction.
• the invention further relates to a constructed with such a carrier assembly construction, in particular a steel structure.
• Steel girders often can not be made in one piece in the length required for the intended use and transported to the jobsite. Rather, prefabricated segments of lesser length are connected to each other on site at the construction site. This is often done via so-called head or face plate joints, in which the front side of the actual carrier profiles molded or attached head plates are bolted together. As a rule, such head plates are aligned perpendicular to the longitudinal direction of the carrier.
• the invention has for its object to provide an alternative support arrangement, which allows a controlled reduction of thermal constraining forces while maintaining the load-bearing function and with a uniform distribution of external forces within the structure.
• the middle segment has at each of its two ends a middle segment head plate and each of the two outer segments has an outer segment head plate at its end directed towards the middle segment,
• the respective outer segment head plate is aligned in such a way that it is complementary to the middle segment head plate opposite it, that together they form a head plate impact,
• the two head plates of each headstock joint are interconnected via connecting bolts or connecting bolts which are guided through recesses in the head plates,
• the recesses in at least one of the top plates of each top plate joint are designed as elongated holes, and
• Both topplates are tilted in opposite directions to a normal plane in the longitudinal direction and the slots are arranged and aligned such that upon thermal expansion or contraction the segments a lateral displacement of the central segment relative to the two outer segments, that is transverse to the longitudinal direction, is possible.
• Screws in a slot connection required, no special components.
• a simple combination of the above-named components achieves a reduction-reducing bearing under the effect of temperature and at the same time maintaining the load capacity for external loads.
• the axial extent of the segments under thermal stress is compensated by lateral deflection of the structure perpendicular to the longitudinal direction.
• the high constraining forces overcome the static friction between the top plates, which is realized by a partial prestressing of the screw connection.
• the lateral deflection of the central segment of the carrier due to external static and / or dynamic loads is not possible for structural reasons.
• the segments contract again, whereby a laterally directed restoring force is automatically generated, which pushes the middle segment back to the starting position.
• the rule of the design will be that the segments of the carrier lie in a line / flight at normal ambient temperature, and that the middle segment shifts sideways when there is a significant increase in temperature. But it can also be based on a system design, which responds in a corresponding manner to temperature drops and thus to contractions of the segments, and in a sense the shifted state is the ground state. If the connecting bolts or connecting bolts are in the ground state approximately in the middle of the slots and the middle segment is pushed out accordingly a little out of alignment, there is - depending on the nature of the temperature change - freedom of movement in both directions.

• the connecting bolts can also be formed or joined (for example welded) on at least one of the two head plates of a top plate joint, inserted through the land holes in the other top plate and secured from the outside by a nut.
• the elongated holes are closed over the entire circumference, that is surrounded on all sides by the top plate, and not open to the outer border out.
• the lateral displacement of the central segment is limited, and the central segment can not fall laterally out of the carrier.
• the maximum lateral displacement of the middle segment is in a structurally realizable area. This ensures that the stability and load-bearing capacity of the carrier is not lowered below a critical value.
• the two head plates of a headstock joint are expediently clamped or clamped against each other during the mounting of the carrier by releasable frictional connection elements.
• connecting bolts are used, in particular in the form of bolts or threaded bolts and / or in the form of cap screws or similar, suitable for forming a screw elements with substantially cylindrical shaft, in the usual way by means of associated nuts - possibly in combination with washers - Or alternatively secured by means of dowel pin or the like and thereby loaded on train.
• the two head plates are braced against each other, for example by appropriately tightening the screws or nuts that the lateral displacement of the central segment is maintained under the influence of temperature (partial bias).
• the carrier is a steel carrier whose individual segments are produced, for example, as rolled profiles with end plates molded or attached, in particular welded head plates.
• the carrier or at least some of its components can also be made of other materials, in particular of modern composite materials (composite materials) or the like.
• the individual carrier segments can in turn be segmented in a conventional manner, that is to say composed of originally separate subsegments - for example with head plate joints oriented perpendicular to the longitudinal direction.
• the combination of the first to third segments or the combination of the third to fifth segments can be regarded as a single segment, such a configuration is covered by the wording of the claims.
• the top plates preferably have flat contact surfaces, which allow a tilt-stable and torsionally rigid support and connection with their respective connection partner, and which form in the lateral displacement of the central segment of the wearer sliding surfaces.
• the contact surfaces may also have a step, which is aligned along the direction of displacement, so that a guide rail for the lateral displacement is realized.
• the head plates may, in particular in the case of solid beams or with closed box profiles have laterally beyond the support profiles flanges to facilitate the attachment of the fasteners and access to them during installation and maintenance. Alternatively, with closed and / or solid profiles, corresponding access openings can also be introduced into the material.
• the support arrangement described is expediently part of a steel construction or a structure, in particular a steel platform or a supporting framework, for example in a nuclear facility or in any other industrial plant.
