Description
Technical field
The present invention relates to field, prefabricated dwelling house, particularly to the attachment structure of steel construction Yu precast slab.
Background technology
Assembled-type house (pin-connected panel house) refers to build house with industrialized production, i.e. the stair, outer in house Wall, balcony, air-conditioning plate etc. are all after the prefabrication of off-site, then transport building site " assembled " to.Wherein steel construction and prefabricated mixed The application of concrete board assembled-type house is relatively broad, and its concrete structure is that the column of steel, crossbeam are assembled into steel frame construction, prefabricated mixed Concrete board makes body of wall, then steel frame construction and precast slab body of wall are carried out rigid assembly.At present, precast slab is solid Being scheduled on column, crossbeam is bearing directly against on precast slab, owing to crossbeam and precast slab are two single parts, There is no between the two and be fastenedly connected.Use for a long time between rear cross beam and precast slab and crack, serious shadow easily occur Ring wall quality.
Summary of the invention
It is an object of the invention to provide one effectively prevents crack from occurring, the company of the high girder steel of quality and precast slab Access node structure.
For achieving the above object, present invention employs techniques below scheme: the company of a kind of steel construction and precast slab Access node structure, steel construction includes column and crossbeam, and the end face of its middle cross beam is fixed on column, and the beam body of crossbeam is partially disposed in advance The inside of concrete slab processed, described precast slab includes bubble concrete layer and reinforced concrete floor, foam concrete Layer is filled in around crossbeam, and reinforced concrete floor is wrapped in around bubble concrete layer and crossbeam, crossbeam and being positioned under it Between the reinforced concrete floor of side, elasticity transition layer is set.
Owing to using above technical scheme, the crossbeam of steel construction and precast slab are fabricated to integrative-structure, and foam mixes Solidifying soil layer can allow crossbeam to produce certain deformation, it is to avoid the load on crossbeam is directly delivered on precast slab, bullet Property transition zone can be with the load being delivered on buffering transverse beam on precast slab, it is achieved the weak company of crossbeam and precast slab Connect, avoid the load on crossbeam to be directly delivered on precast slab further.The most both can effectively ensure that girder steel existed Deformation under work load effect is not retrained by its underpart body of wall, prevents from producing between crossbeam and precast slab splitting simultaneously Seam.Bubble concrete layer and the double buffering of elasticity transition layer, can effectively prevent from producing between crossbeam and precast slab Crack, also reduces the requirement of strength to precast slab simultaneously.Also have crossbeam and precast slab to be made of one structure, spell During dress, it is only necessary to once lift, reduce hoisting difficulty, accelerate work efficiency.

Detailed description of the invention
A kind of steel construction and the attachment structure of precast slab, steel construction 10 includes column 11 and crossbeam 12, wherein horizontal The end face of beam 12 is fixed on column 11, and the beam body of crossbeam 12 is partially disposed in the inside at precast slab 20, and described is pre- Concrete slab 20 processed includes bubble concrete layer 21 and reinforced concrete floor 22, and bubble concrete layer 21 is filled in the week of crossbeam 12 Enclosing, reinforced concrete floor 22 is wrapped in bubble concrete layer 21 and crossbeam 12 around, crossbeam 12 and the reinforcing bar being disposed below Elasticity transition layer 30 is set between concrete layer 22.
Crossbeam 12 and the precast slab 20 of steel construction are fabricated to integrative-structure, and bubble concrete layer 21 can allow horizontal stroke Beam 12 produces certain deformation, and crossbeam 12 absorbs and undertakes a large amount of load, it is to avoid the load on crossbeam 12 is directly delivered to prefabricated On concrete slab 20, elasticity transition layer 30 can also be delivered to the load on precast slab 20 on buffering transverse beam 12, it is achieved Crossbeam 12 and the Weak link of precast slab 20, avoid the load on crossbeam 12 to be directly delivered to precast slab further On 20.Bubble concrete layer 21 and the double buffering of elasticity transition layer 30, can effectively prevent crossbeam 12 and precast slab Produce crack between 20, also reduce the requirement of strength to precast slab simultaneously.Crossbeam is also had to make with precast slab Integrative-structure, time assembled, it is only necessary to once lift, reduces hoisting difficulty, accelerates work efficiency.
Being provided with connector 40 on described crossbeam 12, one end of this connector 40 is fixed on crossbeam 12, and the other end waters Build the inside at reinforced concrete floor 22.Connector 40 is the equal of that one end hauls crossbeam 12, and the other end hauls armored concrete Layer 22, improves the connection reliability between crossbeam 12 and reinforced concrete floor 22.
Described reinforced concrete floor 22 includes armored concrete shell 221 and solid concrete layer 222, the most solid mixed Solidifying soil layer 222 is positioned at the lower section of crossbeam 12, and elasticity transition layer 30 is arranged between crossbeam 12 and solid concrete layer 222；Described The lower section of solid concrete layer 222 be provided with the second bubble concrete layer 23, described armored concrete shell 221 is wrapped in Bubble concrete layer 21, solid concrete layer 222 and the outside of the second bubble concrete layer 23.Change a kind of form of presentation, prefabricated It is mixed that concrete slab 20 includes bubble concrete layer 21, solid concrete layer 222 and the second foam being sequentially arranged from top to bottom Solidifying soil layer 23, and at the outer wrap armored concrete shell 221 of three layer concretes, armored concrete shell 221 is by reinforcing bar Skeleton 223 and concrete composition.Wherein solid concrete layer 222 and the thickness of the second bubble concrete layer 23 in the vertical direction Ratio is 1:8～12.Solid concrete layer 222 can meet the requirement of strength of precast slab, the second bubble concrete layer 23 Body of wall deadweight can be alleviated, thus reduce hoisting difficulty.
Described crossbeam 12 is I-steel, and its I-shaped end face is fixed on column 11, described bubble concrete layer In 21 vallecular cavities being placed in I-steel both sides.
The cross section of described connector 40 takes the shape of the letter U, and its notch is fixed on the work of crossbeam 12 towards crossbeam 12 and side cell wall On the lower wing plate of word steel, the opposite side cell wall of connector 40 is positioned at the inside of solid concrete layer 222.One side channel of connector 40 Wall is stuck in I-shaped lower wing plate and the junction of web of crossbeam 12, is the equal of to hang on crossbeam 12, then welds both Connecing fixing, the link stability of this structure is the highest.
The both sides of described crossbeam 12 are equipped with connector 40, and the connector 40 of its both sides is arranged symmetrically with.At crossbeam 12 The connector 40 that lateral symmetry is arranged so that crossbeam 12 uniform force, thus ensure that the deformation of crossbeam 12 is uniform.
Described connector 40 is bent, by thin bar part, the structure that takes the shape of the letter U, and described connector 40 is along the length side of crossbeam 12 Multiple to being interval with.Spaced connector 40 foot can ensure that and connects by force between crossbeam 12 and solid concrete layer 222 Degree, this structure is lightweight relative to all-in-one-piece connector 40, it is also possible to cost-effective.
The thickness of described elasticity transition layer 30 is 0.5～3cm.Described elasticity transition layer 30 is rock wool or the poly-ammonia that foams Ester.The preferred thickness of elasticity transition layer is 1cm.
