Abstract

The invention aims at overcoming the defects existing in the prior art and aims at providing an explosionproof energy-consumption lightweight steel construction column which has the capabilities of improving the explosionproof capability of a lightweight steel column, reducing the bearing capacity reduction caused by buckling failure of the lightweight steel column and preventing whole structure collapse caused by toppling of the lightweight steel column, thus avoiding person casualty accidents. A technical solution adopted by the invention is an explosionproof energy-consumption lightweight steel structure column which comprises the lightweight column, a foamed aluminum layer enclosed by steel plates, and a lightweight steel cover plate, wherein the steel column is positioned in an intermediate layer of the explosionproof energy-consumption lightweight steel structure column; the foamed aluminum layer enclosed by the steel plates comprises a first foamed aluminum filling layer and a steel sleeve, wherein the steel sleeve consists of mutually connected steel plates which encircle a steel column; the first foamed aluminum filling layer is arranged between the steel sleeve and the steel column.

Description

Antiknock power consumption lightweight steel construction post
Technical field
The invention belongs to technical field of buildings, particularly relate to a kind of antiknock power consumption lightweight steel construction post.
Background technology
In China, light section steel structure is used for individual layer, multi storied factory building, the light section steel structure hotel of 2 ~ 3 layers, the multilayer residential construction etc. of office building and earthquake-stricken area.But LIGHT WEIGHT STEEL STRUCTURES is more responsive to Blast Load effect, and the capability of antidetonance is reported to the leadship after accomplishing a task relatively.As the light steel column of the most important supporting member of light section steel structure, under Blast Load effect, drag obviously reduces, once destroy, may chain reaction be caused and cause whole building structure across collapsing.Therefore, the anti-explosion design of light steel column is very important.
Summary of the invention
The defect that the present invention exists to overcome prior art, the object of this invention is to provide a kind of antiknock ability that can improve light steel column, reduce the supporting capacity decline that light steel column buckling failure causes, prevent light steel column topple and cause overall structure to collapse, thus avoid the antiknock power consumption lightweight steel construction post of personnel casualty accidents.
The technology used in the present invention solution is a kind of antiknock power consumption lightweight steel construction post, comprise light steel column, foamed aluminium layer that steel plate is gone along with sb. to guard him and light steel deck-plate, described steel column is positioned at the intermediate layer of antiknock power consumption lightweight steel construction post, the foamed aluminium layer that described steel plate is gone along with sb. to guard him comprises the first filled with foam aluminum layer and steel bushing, described steel bushing is made up of the steel plate that is interconnected of going along with sb. to guard him at steel column, and the first described filled with foam aluminum layer is arranged between steel bushing and steel column.
The span centre H/3 intra-zone of described light steel column is filled with the second filled with foam aluminum layer, and the two ends section in this region is provided with light steel deck-plate.
Described light steel deck-plate comprises welding point and Light steel sheet, and the foamed aluminium layer that the second filled with foam aluminum layer adopting light steel deck-plate to be filled by light steel column span centre H/3 intra-zone by the welding point being arranged on Light steel sheet corner and steel plate are gone along with sb. to guard him is welded to connect.
Compared with prior art, the beneficial effect that the present invention has is: by the physical characteristic ability of the power consumption energy-absorbing of foamed aluminium layer, the resistance to tension of steel bushing, foamed aluminium energy-absorbing material is added in light steel column span centre H/3 region, be combined into the light steel column of antiknock energy-absorbing rectangle of " sleeve parcel sandwich " formula, the bending rigidity adding the light steel column of rectangle effectively stops the span centre region of rectangle light steel column that buckling failure occurs, thus improve its vertical bearing capacity, avoid personnel and facility cause damage and fracture within doors.
