Abstract
A structural member comprises an elongated hollow case including at least two thin metal shells , each side end of the shells having a flange along its entire length and the flanges facing each other to form the hollow case, at least one of reinforcing end piece to be engaged with an end portion of the case, and a filler moulded into the case. A reinforcing plate is attached by using an adhesive such as epoxy resin to an inner surface of each of the thin metal shells to improve a tensile strength of the structural member. In addition, the reinforcing plate is provided with at least one cut-out portion and an appropriate number of projections formed on a side of the cut-out portion. The adhesive filling the cut-out portions functions as an additional means for improving the tensile strength of the structural member.
Description
Invention field
The present invention relates to a kind of structural element, it has a thin metal-back of elongate hollow that is full of filler; Particularly relate to a kind of new-type structural element, it has attached to the stiffener on the thin metal-back inwall of elongate hollow, to improve the hot strength of structural element.
Background technology
In general, be to utilize timber, concrete, metal or their synthetic to make such as structural element such as pillar, column, bearing, staking out, crossbeams according to special-purpose.
Specifically, the structural element of being made by concrete is owing to having high compression-strength and economy is widely used in building field.In addition, another advantage of this structural element is easily to obtain the structural element of different shape by designing various models.Yet column of Xing Chenging and bearing generally are unsuitable for as decorative articles like this, and this is because they have rough surface features and non-aesthetic appearance.Therefore, need to utilize rough surface, so that member can be used in exquisite occasion by timber and/or metal additional modified elements trimming concrete component.
Therefore, the hollow metal structural element that materials such as utilization such as aluminium, aluminium alloys, stainless steel, galvanized steel, special steel, copper and copper alloy are made is owing to have moving outward appearance, high anti-corrosive properties and easy application property, thereby be used for various structural element more and more, in support post, tie-beam, decoration bearing and similar item.In this hollow metal member, need relatively large thickness bearing, thereby cause material/manufacturing cost to increase to fixed load.
So, once attempted to utilize structural sections bending or that inwardly be flute profile reducing the hollow metal thickness of structure, thereby improve the buckling strength of metal construction and reduce dynamic moment of inertia.Yet because the shaping of the given shape of hardware can increase manufacturing step, therefore the manufacturing cost of this hardware still keeps higher relatively.In addition, may run counter to desire with the method that reduces cost by reducing hardware thickness, because member damages when being subjected to foreign impacts easily.
Therefore, for the specific purpose that improves stretching and compressive strength, various structural element have been developed.
Promulgation discloses a kind of structural element of using with a base combination of being suitable for for the applicant's United States Patent(USP) Nos. 5,263,297 and 5,457,929, and this structural element comprises: the thin metal-back of elongate hollow; An end of shell in the interlock of a reinforcement extremity piece, has a through hole on this reinforcement extremity piece; And a kind of filler is molded in the through hole of hollow shell and reinforcement extremity piece.Disclosed reinforcement extremity piece can embed in the concrete fill in the above-mentioned patent, thereby prevents the two ends distortion of shell in the process of concrete grout being injected shell, and prevents that in the transportation of structural element and work progress the two end portions of structural element from breaking or rupturing.
A major defect of said structure member is that they can only support medium load basically.In other words, they can not be used to bear the structure that the occasion of big load, particularly bridge railing, house, building etc. bear big tensile load.
Summary of the invention
Therefore, a main purpose of the present invention provides a kind of structural element, and it has a thin metal-back, even this metal-back can bear very big tensile load.
Above-mentioned and other purpose of the present invention can realize that this structural element comprises by a kind of like this structural element is provided:
An elongate hollow cover, it comprises at least two thin metal-backs, and described metal-back has a flange that bends inwards along whole length respectively on their every side end, and the bending flange is faced and the formation hollow cover each other mutually;
A pair of stiffener, they are respectively on the inner surface attached to each metal-back; And
A kind of filler, it is molded in the hollow cover.
