Benefits of technology

"The present invention is a method for making a structural support, such as a floor or bridge deck, using open core elements faced with upper and lower steel skins that are welded together and over which a layer of concrete is poured. The invention includes the modules, the overall structural support, and the method of making the same. The technical effects of the invention include increased strength and durability of the structural support, as well as reduced labor and materials costs. Additionally, the invention allows for the inclusion of steel projections and utility connections in the structural support, further increasing its strength and durability."

Problems solved by technology

However, the use of such hollow core panels has been inhibited because of difficulties in fabricating the panels in an efficient and cost effective manner.

Embodiment Construction

[0010]Referring first to FIG. 1, there is shown a portion of a deck 10 or floor useful, for example, in the construction of a bridge or a building, in which a series of long and relatively narrow modules 11 are joined together and covered with a poured concrete slab 12. Each of the modules 11 could be made of any desired dimensions, but for use in a floor deck, for example, module 11 could have a depth or thickness of 16 in., a width of 8 ft. and a length of 50 ft. To fabricate a deck 10 50 ft. long and 64 ft. wide, eight modules 11 would be joined along their long edges, as partly shown in FIG. 1.

[0011]Each deck module 11 includes a hollow core element 13 of the type described and manufactured in accordance with the method disclosed in my above identified patent application. The hollow core element 13 includes a stack of long, narrow corrugated paperboard strips 14, each of which in the embodiment shown comprises a fluted web 15 and a smooth web 16 joined with a suitable adhesive. ...

Abstract

A composite structural support which may be utilized as a beam or assembled with similar supports to form a building floor or a bridge deck utilizes an open core element, made preferably of suitably treated fluted paper, upper and lower thin steel skins, and a layer of concrete poured over the top skin. Modules comprising the hollow core element and the upper and lower steel skins are fabricated to lengths required for building floor and bridge spans and, when joined by welding the upper and lower skins of adjacent elements along their full lengths, provide a floor or deck structure of a large span

Description

BACKGROUND OF THE INVENTION[0001]The present invention pertains to a lightweight hollow core structural building element which can be used as a beam or can be joined with other elements to form a floor or deck panel.[0002]The potential for the use of hollow core elements in the construction of buildings and other structures has been known for many years. Hollow cores of corrugated or honeycomb paper or metal sheet material, enclosed by upper and lower skin panels or sheets, have long been used or proposed for use as floor, wall and roof panels for buildings. However, the use of such hollow core panels has been inhibited because of difficulties in fabricating the panels in an efficient and cost effective manner.[0003]In my co-pending patent application Ser. No. 11 / 476,474, entitled “Method and Apparatus for Manufacturing Open Core Elements from Web Material”, filed Jun. 28, 2006, which application is incorporated by reference herein, there is disclosed a system for manufacturing holl...
