Description
Technical field
The utility model relates to building structure technology field, particularly the connecting structure of a kind of precast concrete plank and girder steel.
Background technology
For the connection of the precast concrete board members such as such as SP prestressed cored slab and girder steel, mostly traditional method is to arrange steel plate or angle steel built-in fitting at the bottom of plate, by with girder steel weld the connection realizing precast plate and girder steel.The built-in fitting of this kind of method need be pre-buried when plate makes, and it is larger by the impact of plate manufacture craft and main muscle layout, especially for precast hollow slabs such as SP plates, because the restriction of precast plate production technology, burying underground of built-in fitting is very restricted, cause during site operation and need overhead welding, all have larger adverse effect for speed of application and welding quality.
Summary of the invention
The purpose of this utility model is the connecting structure providing a kind of precast concrete plank and girder steel, it has flexible arrangement, it is simple to make, construction fast, good economy performance, anti-seismic performance are good and can improve the feature of floor shear resistance.
For achieving the above object, the technical solution of the utility model is:
A connecting structure for precast concrete plank and girder steel, is characterized in that, comprises, precast concrete plank, girder steel, anchor bar; Described precast concrete plank side is positioned on girder steel; Described anchor bar top is anchored in described precast concrete plank, and bottom is connected with described girder steel by welding.
Further, described anchor bar is bent into fold-line-shaped by reinforcing bar, and its top is the linear extended along described precast concrete plank length direction, and anchor bar bottom is and the parallel plane straightway in described girder steel top flange.
Again, described precast concrete plank plate end is close in described anchor bar bending place.
In addition, described anchor bar is when described precast concrete plank makes or be anchored in the lump in precast concrete plank after completing.
Further, described anchor bar upper weld has the transverse reinforcement vertical with described precast concrete plank length direction.
Further, described precast concrete plank two pieces is oppositely arranged, two pieces of precast concrete plank sides are held on girder steel top flange, the longitudinal reinforcement parallel with described precast concrete plank length direction is placed in the plate seam that between the precast concrete plank be disposed adjacent side by side, concreting is formed and plate latasuture, and concreting.
Again, the transverse reinforcement vertical with described precast concrete plank length direction is placed in the seam (plate end seam) between the described precast concrete plank plate end being shelved on described girder steel top flange.
There is cast-in-situ concrete layer above described precast concrete plank, form superimposed sheet, in described cast-in-situ concrete layer, have steel mesh reinforcement.
Described girder steel top flange plane be vertically provided with along its length some pegs or vertically weld some shear reinforcements.
Precast concrete plank described in the utility model is hollowcore slab or solid slab.
Described precast concrete plank is hollowcore slab, and described anchor bar is arranged in the core bore of this hollowcore slab, and concrete perfusion.
The beneficial effects of the utility model:
1. connecting structure of the present utility model, anchor bar welds with girder steel in plate end seam, the problems such as the site operation speed that the traditional method solving the prefabricated assembled floors such as such as SP plate and steel beam connecting joint exists is slow, welding quality should not ensure, the popularization for prefabricated assembled floors such as SP plates has great importance.
2. connecting structure of the present utility model, makes simple, only needs an anchor bar to complete; Flexible arrangement, can according to typesetting and concrete condition adjustment, and because it can carry out after the hollowcore slabs such as SP plate complete, the manufacturing schedule for hollowcore slabs such as SP plates does not affect; Be easy to adjustment, when the out-of-flatness of steel beam surface local, can suitably adjust rear welding, applicability is strong, has very large promotional value.
3. connecting structure of the present utility model, for hollow pre-fabricated panels, because concrete perfusion carrys out anchor bar in core bore, therefore, can improve the shear-carrying capacity of precast plate.
4. connecting structure of the present utility model, has certain flexibility under stronger geological process, fragility can not occur and disconnect, and connects simultaneously reliable, can consume geological process, namely have good anti-seismic performance in guarantee.
