Beam assembly and construction erected therewith

Abstract

A beam assembly contains a substantially straight beam, which is arranged between two bearings and extends in a longitudinal direction. The beam assembly contains at least three segments, which are arranged one behind the other in the longitudinal direction and which are connected to each other by two head plate joints. The three segments include a middle segment and two outer segments. The bearings are prevented from moving in the longitudinal direction. The beam assembly permits controlled relief of thermal constraining forces while the load-transferring function is simultaneously maintained and while external dynamic forces are evenly distributed within the construction. Accordingly, this is achieved in that the middle segment has a middle segment head plate at each of the two ends of the middle segment and each of the two outer segments has an outer segment head plate at the end of the outer segment directed toward the middle segment.

1 . A beam assembly, comprising:
 two bearings being obstructed from displacement in a longitudinal direction;   a generally rectilinear beam disposed between said two bearings, and extending along the longitudinal direction, said rectilinear beam having two head plate joints and at least three segments including a central segment and two outer segments, disposed one behind the other in the longitudinal direction and connected to one another via said two head-plate joints, and wherein:
 said central segment having a central-segment head plate at each of its two ends; 
 each of said two outer segments having an outer-segment head plate at an end directed toward said central segment; 
 each said outer-segment head plate being oriented in a complementary manner in relation to said central-segment head plate disposed opposite said outer-segment head plate, such that, together, they form one of said head-plate joints; 
 said central-segment head plate and said outer-segment head plate of each of said head-plate joints having apertures formed therein and connected to one another via connecting bolts guided through said apertures in said head plates; 
 said apertures in at least one of said head plates of each of said head-plate joints configured as slots; and 
 said two head-plate joints are inclined in opposite directions in relation to a plane normal to the longitudinal direction and said slots are disposed, and oriented, such that, in a case of thermal expansion or contraction of said segments, said central segment can be displaced laterally relative to said two outer segments. 
   
     
     
         2 . The beam assembly according to  claim 1 , wherein each of said central-segment head plates has an inclination axis oriented perpendicularly to the longitudinal direction. 
     
     
         3 . The beam assembly according to  claim 2 , wherein the inclination axes of said two central-segment head plates are oriented parallel to one another. 
     
     
         4 . The beam assembly according to  claim 3 , wherein said two central-segment head plates are at an equal angle of inclination in relation to a plane normal to the longitudinal direction. 
     
     
         5 . The beam assembly according to  claim 4 , wherein the angle of inclination ranges between 30° and 60°. 
     
     
         6 . The beam assembly according to  claim 3 , wherein said slots are oriented perpendicularly to the inclination axis of said central-segment head plate. 
     
     
         7 . The beam assembly according to  claim 1 , wherein said apertures in said central-segment head plates are configured as slots and said apertures in said outer-segment head plates are configured as round holes. 
     
     
         8 . The beam assembly according to  claim 1 , wherein said slots are closed over an entire circumference. 
     
     
         9 . The beam assembly according to  claim 1 , wherein said connecting bolts are selected from the group consisting of threaded bolts and cap screws. 
     
     
         10 . The beam assembly according to  claim 1 , wherein said two head plates of one of said head-plate joints, in a definitively installed state, are braced against one another so as to maintain a lateral displaceability of said central segment under an action of temperature. 
     
     
         11 . The beam assembly according to  claim 1 , wherein said rectilinear beam is a steel beam. 
     
     
         12 . The beam assembly according to  claim 1 , wherein said rectilinear beam is oriented vertically. 
     
     
         13 . The beam assembly according to  claim 4 , wherein the angle of inclination is 45°. 
     
     
         14 . A construction, comprising:
 a beam assembly according to  claim 1 .   
     
     
         15 . The construction according to  claim 14 , wherein said beam assembly is a steel platform.
