Description

A kind of prefabricated assembled steel-concrete composite beam that adopts peg to connect
Technical field
The utility model belongs to the connection structure field of building element, and the beam-plate that is specifically applicable to how high-rise steel-concrete combined structure assembled-type house connects in structure.
Background technology
China starts to realize the application of building industrialization in the 1950's, uses for reference the technical system of the former Soviet Union, Popularization And Development prefabricated components and prefabrication in industrial premises and house. To the eighties in 20th century, precast concrete was once being obtained good achievement in research and development trend, but was limited to economic condition and technical merit at that time, and prefabrication does not obtain large-scale promotion and uses. After the nineties in 20th century, because cheap labour occurs in a large number, the reasons such as commerical ready-mixed concrete technical development, prefabrication is applied constantly and is reduced in civil buildings, and development has entered the low ebb phase. And in recent years, along with domestic economy grows continuously and fast, labor cost improves constantly, the consciousness of energy-conserving and environment-protective becomes main flow, China also increases gradually in the structural research of prefabrication and application, many relevant policies regulations that country puts into effect encourage business enterprise expand to use prefabrication, and this all makes building industrialization march toward a new stage.
In prefabrication structure, prefabricated assembled steel-concrete combined structure occupies more and more consequence. It can alleviate deadweight compared with prefabricated assembled concrete structure, reduces geological process, shortens construction period, increases structure ductility etc., compared with steel construction, can reduce steel using amount, increases the rigidity of structure, stability and globality etc.
Prefabricated assembled steel-concrete composite beam is a kind of novel combination beam structural form, and wherein H section steel beam and armoured concrete slab are prefabricated components, can be linked and packed fast, and composition overall structure. The connecting elements speed of application of prefabricated assembled concrete floor and H section steel beam is very fast and structure manufacture quality is higher, can effectively economize on resources and the energy, improve material in the effect realizing aspect building energy conservation and structural behaviour, reduced building waste for the impact of environment and job site for place environmental demand, improve building function and structural behaviour, meet China's building trade Green Development requirement, can promote to reach predetermined target for energy-saving and emission-reduction.
Traditional concrete floor and H section steel beam be connected structure and cast-in-situ steel reinforced concrete and beam to be connected structure difficulty of construction larger, working procedure complexity, material usage is many, construction quality is unstable, building complete period energy consumption is high. Therefore develop the shortcoming that is connected structure that is connected structure and cast-in-situ steel reinforced concrete and beam that a kind of prefabricated assembled steel-concrete composite beam overcomes traditional concrete floor and H section steel beam, significant and be worth.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model proposes a kind of prefabricated assembled steel-concrete composite beam that adopts peg to connect, its simple structure, excellent earthquake resistance, energy-conserving and environment-protective, and there is higher efficiency of construction and construction quality.
The technical scheme the utility model proposes is:
A kind of prefabricated assembled steel-concrete composite beam that adopts peg to connect, mainly comprise prefabricated reinforced concrete floor, H section steel beam and peg shear connector, it is characterized in that correspondence position welding shearing resistance peg on described H section steel beam, precast rc slab docks with the H section steel beam of laying by the reserved through hole in the position at corresponding peg, finally fills reserving hole by perfusion without contraction self-compacting high-strength concrete inserts and is linked to be entirety.
Described H section steel beam top flange is welded shearing resistance peg in advance, and peg is welded on the symmetrical position in center, top flange or center, top flange along girder steel axis direction.
Described prefabricated reinforced concrete floor is inner reserved corresponding with girder steel weld stud position for placing the through hole of shearing resistance peg, and through hole can be reserved as circular opening or square hole.
The described concrete fill that the inner reserved through hole of prefabricated reinforced concrete floor is poured into is nothing contraction self-compacting high-strength concrete inserts.
Described girder steel and prefabricated reinforced concrete floor can be realized factory's preprocessing, assemble fast at the construction field (site) the function of moulding.
Compared with prior art, the utlity model has following beneficial effect:
1, the utility model adopts the prefabricated assembled steel-concrete composite beam that peg connects, and boxes out and all can complete according to on-the-spot actual demand on girder steel on the welding of peg and prefabricated concrete floor, has ensured construction precision and quality.
2, in the through hole that the utility model is connected with girder steel on precast slab, build without shrinking self-compacting high-strength concrete inserts, this type of inserts and peg have good adhesive property, make peg there is good opposing horizontal shear and the performance of pulling capacity, improve the globality of structure, there is good ductility and anti-seismic performance.
3, the member such as precast slab and girder steel that the utility model adopts is all prefabricated in the factory, and making quality is high, and assembly connection at the construction field (site), has reduced situ wet job execution. After lifting docking, fast pouring, without shrinking self-compacting high-strength concrete inserts, has shortened the engineering time, has improved building industrialization efficiency of assembling, has good promotional value.
