摘要:
The present invention relates to a method of forming a reinforced hollow member. The method comprises the step of inserting a structural reinforcement insert into a hollow member. The structural reinforcement insert is then positioned in the hollow member such that the structural reinforcement insert and hollow member define at least one fluid passageway. A structural adhesive is applied in the fluid passageway to lock the structural reinforcement insert in the hollow member.

A fire in an enclosed space in an aircraft is, for example, visually detected early since smoke generated by a beginning fire is initially permitted to escape from the enclosed space. The enclosed space is, for example, an overhead luggage bin or a goods container holding food or freight. The smoke can pass through a flow passage either in the form of a gap or a leak between a lid and walls, or between a door and a door frame, or between walls and other walls joined together. Intumescent material is installed along the gaps or leaks and expands into the gaps or leaks when the fire has generated a temperature sufficient for causing the expansion of the intumescent material. Preferably a guide surface assures that the intumescent material expands into the gaps and leaks and cannot expand away from gaps and leaks.

Plasterboard panels (A,B) formed by layers of cardboard (1,3) with a sandwiched plaster sheet (2) and by layers of cardboard (4,6) with a further sandwiched plaster sheet (5), are clamped between a female half mold part (C) and a male half mold part (D) of a forming press, are spread with vinyl adhesive or other suitable water-based adhesive at the layers of cardboard (3,4). In each one of the two panels, the plaster sheet (2,5) is fractured radially and the layer of cardboard (3) on the outside of the curvature is stretched and the layer (4) on the inside is compressed. The bonding of the layer of cardboard (3) of the first panel (A) to the layer of cardboard (4) of the second panel (B) forces the two panels to a permanent, stable, equilibrium of the respective opposite curving tensions.

Site cast or pre-cast columns aligned and braced by pre-cast pre-stressed floor beams are used to erect a concrete skeleton structure for a building. The ends of the horizontal beams are imbedded in the columns at floor levels to stabilize and complete the skeleton. The horizontal beams are pre-stressed and are cast with passages that permit insertion of continuous reinforcing tendons into a network throughout each floor level. The tendons are subsequently post-tensioned so to tie the beams together and to the columns to reinforce the skeleton. Slab drop-forms starting at the roof and progressing floor-by-floor downward allow monolithic post-tensioned floor slabs to be cast to tie the skeleton into a unitary structure. The beams are usually integrated (buried) into each monolithic floor slab, keyed, doweled and bonded with bonding agent at cold joints to become a part of the slab structure.

Disclosed are a panel for repairing and reinforcing a concrete body, a multi-purpose anchor, an anchor for level adjustment and injection a method for repairing and reinforcing the concrete body using the same, which can connect adhesives and anchors at weak parts of the concrete body, which is neutralized, aged, deteriorated, cracked due to water leakage, or segregated, or at parts requiring the repair and reinforcement due to a change in use environment. The composite reinforced panel includes lightweight concrete, high strength concrete or a steel plate and reinforcing means, thereby being effectively prevented from bad environments causing a drop of reinforcing capacity, providing good heatproof and fireproof properties, and maximizing merits of materials used as the reinforcing means. The multi-purpose anchor has a bolt and an injection pipe, fixes the panel to the concrete body effectively, serves as a spacer maintaining a prescribed interval between the panel and the concrete body, and serves to inject filler and discharge the inside air to the outside, thereby improving construction efficiency. The anchor for level adjustment and injection has a male screw and a female screw at an end and an injection pipe of a straw type, thereby improving the construction efficiency when the concrete panel is installed.

One embodiment of the present invention provides for a method of placing a concrete structure in a generally horizontal position. The method includes building the concrete structure in an essentially vertical position, the concrete structure being defined by a first end. The concrete structure is pivotably supported at a support location proximate the first end while the concrete structure is in the essentially vertical position. The concrete structure is then pivoted about the support location to move the concrete structure from the essentially vertical position to the generally horizontal position.

A method for sealing a roof is disclosed herein. The roof is of the type comprising an inclined substrate and a first layer of shingles. The first layer of shingles has a first side and a second side wherein the first layer of shingles first side is attached to the substrate. The method comprises a first party selecting a second party to seal the roof. The first party provides a waterproof membrane having a first side and a second side to the second party. The second party positions the membrane first side adjacent at least a portion of the first layer of shingles second side. The second party attaches a second layer of shingles to the substrate, wherein the second layer of shingles is adjacent the membrane second side.

A portable roof panel structure assembly mechanism that may be transported to a construction site and that is used to automatically assemble roof panel structures at the site. The assembly mechanism includes a purlin feeder, subpurlin clamping mechanisms and feeders, and a diaphragm feeder. The purlin feeder lifts a purlin into position, and advances the purlin into an assembly station. The subpurlin feeders insert a subpurlin into each of a plurality of subpurlin clamping mechanisms, and the clamping mechanisms advance into the assembly station and hold the subpurlins against the section of the purlin that has been advanced. The diaphragm feeder places a diaphragm onto the subpurlins and the purlin at the assembly station. The components are attached by automatic nailers.
