A steel tube supporting construction structure for beam transfer floor in high-rise building and a construction method therefor are provided. The construction structure includes an upper beam formwork, a lower beam formwork, and a stand. The lower beam formwork is provided with a first column formwork on a top wall thereof, the upper beam formwork is detachably provided with a second column formwork on the bottom wall thereof. The second column formwork is detachably provided with a bottom formwork on a lower end of the second column formwork. The second column formwork is provided with a connecting member respectively on an upper end and a lower end thereof for connecting with the upper beam formwork, the lower beam formwork and the bottom formwork. The first column formwork and the second column formwork are each detachably provided with an upright barrel formwork in the vertical direction.

The invention relates to a unit that comprises a closing piece arranged on a horizontal surface onto which side panels are secured, for which purpose the closing piece has side perforations arranged longitudinally and in line with projections that the side panels have on their lower edge. The side panels are vertically secured onto the closing piece via clips or the like secured onto the closing pieces. Thanks to the structural features of the parts and their engaging design, an assembly is obtained which is easy to assemble and dismantle, allowing girders to be built directly on site, as well as allowing the removal of forms from girders with complex geometries (holes, section reductions, etc.).

A metal concrete form panel having a face sheet secured to a perimeter flange that includes side rails and end rails. One or more tie ribs extend between the end rails. A bolt block is secured in each corner to the perimeter flange where the side rails meet the end rails. A bar is located spaced inside each side rail and extended between and secured to each of the pair of opposing bolt blocks of the associated end rail and also secured to each intervening tie rib and to the face sheet.

A stacking clip suitable for use with a concrete forming system having one or more frame elements having one or more ribs formed on a rail. The stacking clip allows an extension component to be coupled to the stacking clip and to hence extend the height or the width of the frame element.

A system and a method for concrete forming uses a self-driven formwork machine. The self-driven machine is provided with a lifting system, for lifting objects from the ground like a rebar reinforcing cage. The present invention avoids the use of cranes, such that construction cost and execution time, are greatly reduced. The present invention is preferably used for constructing a capital or lintel on top of a pillar, although it can also be used for constructing other overhanging concrete structures.

A lightweight concrete nailer form preferably includes a semi-tubular member and a plurality of cross members. The semi-tubular member includes a bottom wall, a first sidewall, a second sidewall, a first upper flange and a second upper flange. A height of the first and second sidewalls may also increase over a length of the semi-tubular member to form a tapered semi-tubular member. A plurality of openings are preferably formed through the bottom wall and the first side wall for the flow of lightweight concrete. The cross member preferably includes a bottom flange, an upright member and a top flange. An opening is formed through the upright member for the flow of lightweight concrete. The plurality of cross members fit inside the semi-tubular member. The semi-tubular member may be stacked with a second semi-tubular member. A cover plate may be attached to a top of the semi-tubular member.

In summary the invention described herein is broadly directed to a module for forming a reinforced concrete structure comprising (a) a formwork member that defines a cavity, (b) a reinforcement structure in the cavity, and (c) at least one formwork brace interconnecting the formwork member and the reinforcement structure.

A device for assisting to secure a bridge support bracket to a beam, the device comprising: a support frame, a hook to secure the support frame to the beam, a clamp to grasp and hold the bracket, and a pivot axle to pivotally connect the clamp to the support frame. When attaching at least two spaced apart such devices to the beam, then clamping a support bracket in each of the at least two spaced apart devices, both support brackets can be pivoted to a position where wood boards attached to the top of the support brackets are held in a not horizontal position. By then placing a wood stud in a position where it spans the two support brackets and attaching the wood stud to the respective bracket wood boards, a workman can then further pivot the support brackets to where the wood boards extend horizontally away from the beam.
