Joint structure of steel plate concrete structure

Abstract

Although a steel plate concrete structure (SC structure) is generally provided with extremely excellent performance in view of the structure, in view of building operation, it is necessary to weld and joint SC steel plate units at a building site. It is an object of the invention to provide a mechanical joint structure of SC steel plate units comprising surface steel plates or surface steel plates and constituent members thereof by omitting field welding which has been needed conventionally in view of a building procedure. According to the invention, as a joint structure for achieving the above-described problem, there is provided a joint structure of a steel plate concrete structure, in which a joint member of an H type or an I type comprising a steel plate or steel bar is arranged at a position of riding over SC steel plate units and a stress produced at a surface steel plate of the SC steel plate unit is transmitted by concrete cast into a space of the SC steel plate unit after installing the SC steel plate unit.

What is claimed is:  
     
         1 . A joint structure of a steel plate concrete structure, wherein a joint member of an H type or an I type comprising a steel plate or steel bar is arranged at a position of riding over SC steel plate units and a stress produced at a surface steel plate of the SC steel plate unit is transmitted by a concrete cast into a space of the SC steel plate unit after installing the SC steel plate unit.  
     
     
         2 . The joint structure of a steel plate concrete structure according to  claim 1:   wherein a steel plate formed with a pertinent number of pieces of studs is formed to project to a portion of the space substantially at a central portion of a member for constituting a web of the joint member.    
     
     
         3 . The joint structure of a steel plate concrete structure according to  claim 1:   wherein a pertinent number of pieces of projections are formed at a member of constituting a web of a joint member.    
     
     
         4 . The joint structure of a steel plate concrete structure according to  claim 1:   wherein a steel plate formed with a pertinent number of pieces of cylindrical projections is formed to project to a portion of the space substantially at a center portion of a member for constituting a web of a joint member.    
     
     
         5 . The joint structure of a steel plate concrete structure according to  claim 1:   wherein a plurality of pieces of steel plates each formed with a pertinent number of pieces of studs or cylindrical projections are formed to project to a portion of the space at a member for constituting a web of a joint member.    
     
     
         6 . A joint structure of a steel plate concrete structure, wherein a joint member comprising a steel plate with a stud is arranged at a position of riding over SC steel plate units, the joint portion is covered and a stress produced at a surface steel plate of the SC steel plate unit is transmitted by a concrete cast into a space of the SC steel plate unit after installing the SC steel plate unit.  
     
     
         7 . A joint structure of a steel plate concrete structure, wherein SC steel plate units are jointed by stepped difference portions or recessed and projected portions formed at end portions thereof, the SC steel plate units are mechanically jointed by a connection piece of a bolt or the like from an outer side of the joint portion and a stress produced at a surface plate of the SC steel plate unit is transmitted by a concrete cast into a space of the SC steel plate unit after installing the SC steel plate unit.  
     
     
         8 . A joint structure of a steel plate concrete structure, wherein SC steel plate units constituting a recessed and projected shape to constitute end portions thereof in a mesh shape, are arranged by integrating the recessed and projected portions of the SC steel plate units to each other and a stress produced at a surface steel plate of the SC steel plate unit is transmitted by a concrete cast into a space of the SC steel plate unit.
