Connector for steel structures

Abstract

A steel structural connector, comprising a vertically-oriented connecting body for connecting to columns and a horizontally-oriented connecting body for connecting to beams, where one end of the horizontally-oriented connecting body is connected to the vertically-oriented connecting body. The vertically-oriented connecting body further includes sequentially arranged front sidewall, left sidewall, rear sidewall, and right sidewall. On at least one end of the vertically-oriented connecting body, there are several installation through-holes for connecting to columns. The vertically-oriented connecting body has installation through-holes on one end of each sidewall with an inwardly extending concave portion along the length direction of the vertically-oriented connecting body. The installation through-holes are placed within the concave portion. The present invention enhances the stability and structural strength of connections when used at locations with installation through-holes for external vertical components, while simultaneously connecting both horizontal and vertical components.

What is claimed is: 
     
         1 .

         2 . The connector for steel structures according to  claim 1 , wherein the inward concave portion ( 3 ) is distributed along the length direction of the vertically-oriented connecting body ( 100 ) and is located at the center of each sidewall. 
     
     
         3 . The connector for steel structures according to  claim 1 , wherein the horizontally-oriented connecting body ( 200 ) is provided in a range of 1 to 4, with each horizontally-oriented connecting body ( 200 ) being welded to one sidewall of the vertically-oriented connecting body ( 100 ). 
     
     
         4 . The connector for steel structures according to  claim 1 , wherein the horizontally-oriented connecting body ( 200 ) is selected from the group consisting of steel pipe connectors, I-beam connectors, or C-section steel connectors. 
     
     
         5 . The connector for steel structures according to  claim 1 , wherein the installation through-holes ( 2 ) are located at one end of the vertically-oriented connecting body ( 100 ), and at least two sidewalls of the other end of the vertically-oriented connecting body ( 100 ) are each connected to one of the horizontal connecting bodies ( 200 ). 
     
     
         6 . The connector for steel structures according to  claim 1 , wherein at least two of the horizontal connecting bodies ( 200 ) are each connected to two sidewalls in the middle region of the vertically-oriented connecting body ( 100 ), and the vertically-oriented connecting body ( 100 ) has installation through-holes ( 2 ) at both ends. 
     
     
         7 . The connector for steel structures according to  claim 1 , wherein the front sidewall ( 11 ), left sidewall ( 12 ), rear sidewall ( 13 ), and right sidewall ( 14 ) are sequentially connected. 
     
     
         8 . The connector for steel structures according to  claim 1 , wherein sidewalls of the same width for the front sidewall ( 11 ), left sidewall ( 12 ), rear sidewall ( 13 ), and right sidewall ( 14 ) are interconnected by right-angled wall plates ( 4 ) that are inwardly bent. 
     
     
         9 . The connector for steel structures according to  claim 1 , wherein the front sidewall ( 11 ), rear sidewall ( 13 ), and right sidewall ( 14 ) have the same width and are all smaller than the width of the left sidewall ( 12 ), and the right sidewall ( 14 ) positioned opposite the left sidewall ( 12 ) is interconnected to the front sidewall ( 11 ) and rear sidewall ( 13 ) through right-angled wall plates ( 4 ) that are inwardly bent. 
     
     
         10 . The connector for steel structures according to  claim 1 , wherein the width of the front sidewall ( 11 ) and the right sidewall ( 14 ), both of which have the same width, is smaller than the width of the left sidewall ( 12 ) and the rear sidewall ( 13 ), and the front sidewall ( 11 ) connected to the left sidewall ( 12 ) and the right sidewall ( 14 ) connected to the rear sidewall ( 13 ) are interconnected through right-angled wall plates ( 4 ) that are inwardly bent.
