Abstract

The utility model relates to a compound force-shearing drum with a steel structure, belonging to building materials. The force-shearing drum is mainly characterized in that thick steel bars are crossed and braided together in a spiral form to be a meshed drum wall and straight bars are longitudinally welded along crossed points to strengthen the strength of the drum wall; then web members are respectively welded and tied at each crossed point of the drum wall to form drum cores with the Chinese character of mi in a longitudinal arrangement. Compared with the existing steel frame structure through a great number of tests, the utility model has the advantages of superior strength and stiffness, local stability, overall stability, low cost, easy process and high-speed construction progress, and is an ideal product for the high layer and super-high layer buildings.

Description

Reinforcing bar structure complex shear tube

The utility model belongs to technical field of buildings

At present, the reinforced concrete structure Building technology, can not resemble and be widely used in the super highrise building technical field steel work and steel one reinforced concrete composite structure, its reason is unreasonable the causing of metallic framework mechanical property in the existing reinforced concrete technology, in existing building, mostly adopt concrete structure to be, bar reinforcement upright (vertically) is parallel to each other and surrounds tubular, fine steel rib is then pricked knot or welding with the form vertical surrounding of stirrup in the periphery of thick muscle, its intensity of skeleton made from this structure, rigidity is all lower, and rolled steel dosage is bigger, Japan's " Nikkei Business Daily " reports that recently long Gu Gong company has developed X type cross wise reinforcement structure, can be used for building 400-500 meters high super highrise building.The major defect of this structure is that the X crosspoint is skewness in the axial direction, and the prismatical structure of X type is prolonged axially not isometrical, and stirrup and X structural column do not form organic whole.

The utility model purpose is, according to having weak point in the present building superelevation floor room, ad hocly counted a kind of steel work complex shear tube, it has overcome the weak point of the X type cross wise reinforcement structure of Japanese long Gu Gong company exploitation, this product easily is processed into overall structure in plant produced simultaneously, adopt both while shearing stress of barrel and web member, the mechanics principle that provides confining pressure to the tube inner concrete has been given full play to the high characteristic of steel tensile strength to remedy the major defect of existing reinforced concrete structure again.

Fig. 1 is the utility model structural representation

The compound steel structure shear drum that the utility model is designed, it mainly is this shear tube Formed by barrel, tube stamen two large divisions; Barrel adopts bar reinforcement (1) with spiral form Intersect woollen yarn knitting, the crosspoint adopts the mode of welding, butting to be fixed. Make its one-tenth Be netted barrel, prolong vertically welding straight muscle (3) of crosspoint, to strengthen this shear tube barrel Intensity; Two of web member (2) fine steel rib in the tube stamen, welding, butting are at barrel respectively Each crosspoint on, form " rice " character form structure of longitudinal arrangement, barrel and a stamen abdomen Bar between each the angle in crosspoint be 25 °-65 °. The steel knot that the utility model is designed The diameter of structure complex shear tube, the density of crossbar contact, net string and web member diameter and each Between angle be to determine complex shear tube intensity, rigidity, stable, the monolithic stability of office's cloth Major parameter. Through a large amount of its intensity of test, rigidity, local stability, whole steady Establish a capital well beyond existing steel structure framework, can build 500-600 meters high building, Adopt the designed compound steel structure shear drum of the utility model, the overall weight of its building But decrease, cost also reduce greatly, and this product is easily manufactured in factory simultaneously, fortune Defeated convenient, not yielding in the cargo handling process, can adopt unified standard, broken through in the past The shortcoming that reinforced concrete structure is in layer constructed, and can greatly improve speed of application.

Embodiment:

The designed steel work complex shear tube of the utility model is in manufacturing process, at first intersect with spiral form and knit into barrel with bar reinforcement, then according to the distance between the crosspoint, the web member fine steel rib is welded on respectively on each crosspoint of barrel, form the tube stamen of " rice " font structure of vertically arranging, the angle in each crosspoint is an optimum state for 45 °, prolongs the straight muscle of the vertical welding in each crosspoint on the barrel again, to strengthen the intensity of barrel.In construction, will make ready-made steel work complex shear tube and install and fix, and carry out the monolithic concrete casting then and get final product, and adopt this shear tube greatly to improve speed of application, reduce construction cost according to required quantity.

Claims

1, a kind of metallic framework steel work complex shear tube that is used for high level, super highrise building, it is characterized in that, this shear tube is by barrel, the tube stamen two large divisions form; Barrel adopts bar reinforcement (1) to intersect woollen yarn knitting with spiral form, and the crosspoint is adopted and welded, the mode of butting is fixed; Prolong vertically welding straight muscle (3) of crosspoint; Weld respectively at two of web member (2) fine steel rib in the tube stamen, and butting forms " rice " font structure of vertically arranging on each crosspoint of barrel.

2, steel work complex shear tube according to claim 1 is characterized in that the angle in crosspoint was 25 °-65 ° between barrel and tube stamen web member were respectively.
