Lightweight Crane-Set Forming Panel

Abstract

A forming panel is provided which is particularly useful as a large, crane-set forming panel for forming concrete walls. The forming panel includes a face plate and a frame, the frame including channels having a slot extending longitudinally therealong. The slot is adapted to receive a filler insert having a bushing which includes a flexible barrier having a brush-like element with a plurality of filaments extending into a passage configured to receive either a tie bar or a tie rod. The forming panel preferably includes a shiftably mounted bracket for supporting a waler, scaffold or strongback thereon, wherein the bracket includes an arm which may be pivoted to a position substantially parallel to the frame and its mounting plate for transport and/or storage. The face plate may be provided as a multilayered composite panel and the frame may include rails having grooves on the side opposite the face plate which receive flexible barriers for inhibiting the passage of fine particles of concrete therepast.

Description

[0001]This application claims the benefit of U.S. Provisional Application No. 60 / 885,587, filed Jan. 18, 2007.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention concerns a lightweight metal forming panel used in the construction of concrete or other cementations walls. More particularly, the present invention concerns a forming panel which is constructed with dimensions typical of a crane-set forming panel but lighter in weight, may include a composite face plate and a frame including a resilient barrier, and may feature a reinforcing spine adapted to receive a shiftable bracket which permits sealing against internally placed form connecting elements such as ties bars or tie rods of different configurations and includes a retractable support bracket.[0004]2. Description of the Prior Art[0005]Forming panels are well known in the construction industry as providing a system for retaining flowable cementatious material such as concrete in a desired sha...

AI Technical Summary

Benefits of technology

[0008]These and other objects have largely been addressed by the lightweight crane-set forming panel of the present invention. That is to say, the forming panel of the present invention presents significant improvements over prior art in regard to providing a lightweight panel of a size typical of crane-set forming panels, but presents improved capabilities for inhibiting the passage of fine particles of concrete around the frame or through openings in a face ...

Problems solved by technology

Such loose parts are problematic at a construction site, being broken, misplaced or lost as the forming walls are disassembled or moved.

Moreover, the location for receipt of these attachment members were limited and by necessity often were between reinforced areas of the forming panels and thus placed stress on portions of the panels in locations least configured to accept such stresses and strains.

However, the use of the “O” ring as a sealing member requires relatively frequent replacement and provides limited tolerances to differences in the diameters of the tie rod against which it seals.

Furthermore, the use of the “O” ring ...
