Shaped steel combination structure

Abstract

A shaped steel combination structure includes at least two shaped steels. Each of the shaped steels is a long strip-shaped structure integrally formed from a steel plate by a stamping press. Each of the shaped steels has a back plate having a plurality of welding points and at least one side plate connected to the back plate. The shaped steels are arranged symmetrically with each other, and each of the back plates of the shaped steels is welded to each other at the welding points thereof; wherein the welding points are separated by a distance of 200˜300 mm.

1 . A shaped steel combination structure, comprising:
 a shaped steel, which is a long strip-shaped structure integrally formed from a steel plate by a stamping press, the shaped steel having a back plate and at least one side plate connected to such back plate;   wherein, the number of the shaped steels is at least two, the shaped steels are symmetrically arranged with each other, and each of the back plates of the shaped steels is welded to each other via a plurality of welding points; and   wherein, the welding points are separated by a distance of 200˜300 mm.   
     
     
         2 . The shaped steel combination structure according to  claim 1 , wherein the number of the welding points is from 12 to 35. 
     
     
         3 . The shaped steel combination structure according to  claim 1 , wherein the shaped steel is C-shaped steel, L-shaped steel, H-shaped steel, or square steel. 
     
     
         4 . The shaped steel combination structure according to  claim 1 , wherein the length of the shaped steel is 3000˜10000 mm. 
     
     
         5 . The shaped steel combination structure according to  claim 1 , wherein each welding points is 20˜40 mm long. 
     
     
         6 . The shaped steel combination structure according to  claim 1 , wherein the closest distance of the welding point from the front end of the shaped steel is 10˜30 mm and the closest distance from the rear end of the shaped steel is 10˜30 mm.
