Description
- This invention relates generally to the construction of buildings having a corrugated steel floor panel and, more specifically, to methods of reinforcing such corrugated steel floor panel.
- Steel framed buildings typically have upper story flooring built upon a corrugated steel floor panel spanning the distances between opposed steel framing beams.
- In many situations, especially where the building is being constructed in an earthquake-prone area, the corrugated steel floor panel must be reinforced. In a typical case, the corrugated steel floor panels must be specifically reinforced to withstand sheer forces generated in an earthquake.
- One commonly employed method to reinforce a corrugated steel floor panel is to place channel sections over the top of selected corrugations along the steel floor panels and then weld the downwardly depending channel section ends to base areas on either side of the raised corrugation center. However, the procedures involved in properly welding the channel sections over the corrugations are difficult, awkward and expensive.
- Accordingly, there is a need for an alternative method of reinforcing a corrugated steel floor panel which avoids these problems inherent in the prior art.
- The invention satisfies this need. The invention is a method of reinforcing a corrugated steel floor panel comprising the steps of (a) providing a plurality of steel channel sections, each channel section having a length, a rectangular flat central portion with a pair of opposed long sides and a pair of opposed end sides, and a pair of opposed side walls depending downwardly from each of the long sides of the central portion; and (b) placing the channels sections along the corrugations of the floor panel such that the central portion of each channel section is proximate to the upper area of a corrugation and such that the pair of opposed side walls on each channel section depend downwardly towards a base area of a corrugation, and mechanically attaching the central portion of each channel section to an upper area of a corrugation with retainer pins.
- These and other features, aspects and advantages of the present invention will become better understood with reference to the following description, appended claims and accompanying drawings where:
-
FIG. 1 is a side cut away view of a reinforced corrugated steel panel according to the invention showing a channel section attached to a corrugated panel with retainer pins; -

FIG. 3 is a front cut away view of a reinforced floor panel, according to the invention, showing a corrugated steel floor panel spanning opposed framing beams and a steel channel section attached to the corrugated steel floor panel with retainer pins; -
FIG. 4 is a top front perspective view of a reinforced floor panel according to the invention; and -
FIG. 5 is a top side view of the channel section shown inFIG. 4 . - The invention is a method of reinforcing a corrugated steel floor panel, also referred to as a steel floor system or steel floor assembly. According to the invention, a corrugated steel floor panel is reinforced by mechanically attaching a plurality of steel channel sections to corrugations in the steel floor panel with retainer pins. The invention is a lower cost and faster alternative than traditional methods of reinforcing a corrugated steel floor, which require labor intensive, time consuming, and expensive methods of welding steel.
