Description
Technical field
A kind of concrete and shaped steel combination construction member relate to the civil engineering structure field of engineering technology, are specifically related to a kind of concrete and shaped steel combination construction member with antihunt action and energy-saving and emission-reduction.
Background technology
Modern age the concrete structure buildings' features amount of being big, wide, tall and big, to expend natural resource, the energy, soil etc. a lot, brought a series of secondary face problems accordingly, as it are big to expend natural resource, environment pollution is many, influences sustainable development etc.For this requirement to concrete structure improves accordingly, deepen and comprehensively scientific development.Reinforced concrete frame structure is the building structure that has a large capacity and a wide range.Make useful contribution to society recent decades, but it has fat beams and columns, from great, and the earthquake earthquake that mostly occurs, shortcoming such as it is cumbersome to construct.The high level of civil engineering structure, stride greatly, heavy duty, use simple concrete structure to be difficult to be competent at.Because concrete tensile strength is small in ignoring, therefore structure, the member employing concrete for the Duola district also is irrational.Concrete structure is from great, and it is light to be not so good as steel work.For this reason, break the system of simple concrete structure self.Development steel and concrete structure combination or the structural system of mixing.Steel and concrete respectively have the merits and demerits of self, and the advantage of steel work is the intensity height, from heavy and light, and its shortcoming is a pressurized unstability and not fire-resistant.Steel is applicable to tension, superelevation layer, strides greatly; The rigidity of concrete component is big, and is fire-resistant, be applicable to resistance to compression and be unsuitable for tension, shortcoming be conduct oneself with dignity very big.The earthquake of many reinforced concrete posts, be mostly because during earthquake because terminal anchoring inefficacy of stirrup or stirrup are broken concrete fragmentation, slump.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, and a kind of concrete and shaped steel combination construction member with antihunt action is provided, but industrialized construction easy to use improves efficiency of construction, the reduction of erection time.Technical solution of the present utility model is: a kind of concrete and shaped steel combination construction member, form by high-strength concrete column and the steel and the concrete combination beam that are positioned at its top, high-strength concrete column uses the Materials with High Strength composite spiral reinforcement stirrup, compound beam is combined by concrete floor and shaped steel, and concrete column is connected by bolt, reinforcing bar or angle steel with compound beam.
The node of above-mentioned a kind of concrete and described concrete column of shaped steel combination construction member and compound beam, a kind of in end plate nut connected node, steel bar connecting joints or the truss of angle steel node.
Above-mentioned a kind of concrete and the described concrete column of shaped steel combination construction member are made of vertical muscle of post and composite spiral reinforcement stirrup.
Above-mentioned a kind of concrete and the described compound beam of shaped steel combination construction member for i iron is connected with concrete floor, or use profile iron; Concrete floor is stretched on the web top of profile iron, and welds snakelike reinforcing bar replacement worker shaped steel top flange in shaped steel web upper vertical direction.
The beneficial effects of the utility model are:
(1) alleviates dead load, growth usage space.Reinforced concrete beam tensile region concrete can not be worked, and very big weight is but arranged.Remove and draw the concrete in district to replace with shaped steel, and consider that concrete building plate participates in the pressurized work of beam, so form the compound beam of shaped steel and concrete combination, reduce beam and conduct oneself with dignity about 70%, the pillar cross section reduces and beam itself highly reduces the building gross weight is reduced, and enlarges usage space.
(2) geological process is little, and the middle and high strong spiral stirrup confined concrete post of this novel employing improves concrete column intensity, overcomes the fragility of High Strength Concrete, improves the ability of elastic-plastic deformation of post.
(3) quake-resistant safety is reliable, adopts the compound hoop of high-strength spiral, and stirrup spacing is closeer, and then stirrup does not collapse out and breaks, and concrete just can fragmentation or slump, thereby has avoided collapsing of house.
(4) save building materials, energy-saving and emission-reduction such as following table (actual engineering design with material relatively)
| The concrete column compound beam | Shaped pile frame | Difference |
| Concrete | 567.3m 3 | 851.7m 3 | 284.4m 3 |
| Steel | 220T | 239.2T | 19.2T |
| Economize coal | Reducing emission of carbon dioxide |
| 30N/m 2 | 133N/m 2 |
| 3.53T | 115.6T |
(5) improve efficiency of construction
