Abstract
A flooring system has at least one girder, a first joist coupled to a first side of the girder, and a second joist coupled to a second side of the girder. The flooring system further comprises a joist tightening system that has a first end coupled to the first joist and a second end coupled to the second joist, the joist tightening system pulls the first joist and the second joist toward the girder thereby tightening the first joist and the second joist.
Claims6
A flooring system, comprising:
- at least one girder;
- a first joist coupled to a first side of the girder;
- a second joist coupled to a second side of the girder;
- and
- a joist tightening system having a first end coupled to the first joist and a second end coupled to the second joist, the joist tightening system configured to pull the first joist and the second joist toward the girder thereby tightening the first joist and the second joist,
- wherein the first joist and the second joist are coupled to the girder via brackets, the joist tightening system comprises a bar wherein a first end of the bar is threaded and a second end of the bar is threaded, the joist tightening system comprises a first bracket coupled to a first plate, and the first plate is coupled to the first joist and comprises a second bracket coupled to a second plate, and the second plate is coupled to the second joist, and the joist tightening system comprises a second bracket coupled to a second plate.
