Abstract
The utility model discloses a kind of structure of open pore steel plate shear force, comprise the girder steel be made up of steel beam flange plate (1) and steel beam web plate (2), steel beam flange plate (1) is welded with T-shaped shear connector, described T-shaped shear connector comprises shear connector frange plate (4) and offers the shear connector web (5) of U-lag, U-lag on shear connector web (5) and steel beam flange plate (1) are formed one closed " door opening ", in this " door opening ", be provided with main muscle (6), main muscle (6) is provided with closed stirrup (7).The utility model adopts T-shaped shear connector that concrete slab and girder steel are connected to form entirety, not only have that structure is simple, easy construction, good integrity advantage, and resistance to plucking is effective, and longitudinal shear resistance sexuality by force, is particularly useful for hogging moment region.
Description
Technical field
The utility model relates to a kind of structure of open pore steel plate shear force, belongs to civil works building technology field.
Background technology
Open pore plate shear force key has the people such as Leonhardt to propose in 1987, and it is a kind of steel plate arranging circular hole is embedded in concrete shear connector along force direction.Open pore plate shear force key relies on the concrete in circular hole to resist active force between Steel concrete, and test show that aerial concrete has very large dowel action, and it finally destroys is concrete shearing in hole, and there is not fatigue problem.Therefore, open pore plate shear force key is that concrete slab and girder steel are connected to form entirety, and key constructs cooperative with concrete, be one of critical component of steel-concrete combined structure.
Traditional open pore steel plate shear force gets out circular opening in steel plate, and this hole distance i beam top flange plate and concrete slab all have certain distance.This kind of open pore steel plate shear force also exists self weak point, such as, concrete tenon in shear connector can not repeat to play a role to longitudinal shear resistance, bearing hogging moment region can cause concrete slab along the crack in open pore steel plate shear force main stress direction, destroy globality, and the construction of perforated rebar is more difficult.
Utility model content
The purpose of this utility model is: provide that a kind of structure is simple, easy construction, good integrity, anti-on pull out ability strong, there is good longitudinal shear resistance performance, be applicable to the structure of the open pore steel plate shear force of hogging moment area, to overcome the deficiencies in the prior art simultaneously.
The structure of a kind of open pore steel plate shear force of the present utility model, comprise the girder steel be made up of steel beam flange plate and steel beam web plate, steel beam flange plate is welded with T-shaped shear connector, described T-shaped shear connector comprises shear connector frange plate and offers the shear connector web of U-lag, U-lag on shear connector web and steel beam flange plate are formed one closed " door opening ", in this " door opening ", be provided with main muscle, main muscle is provided with closed stirrup.
The thickness of described shear connector web is 10 ~ 20mm, is highly 60 ~ 120mm.
On described shear connector web, the A/F of U-lag is 20 ~ 40mm, and the spacing between U-lag is 100 ~ 300mm.
Compared with prior art, the utility model has the advantage of: the utility model adopts T-shaped shear connector that concrete slab and girder steel are connected to form entirety, U-lag on shear connector web and steel beam flange plate are formed one closed " door opening ", it is more convenient that this " door opening " runs through main muscle, and after T-shaped shear connector is combined with concrete slab, the contact area of concrete tenon and steel plate can be increased, increase the longitudinal shear resistance ability of combined interface, and the shear connector frange plate on T-shaped shear connector can replace reinforcing bar to resist hogging moment, effectively prevent concrete slab from resisting hogging moment and producing cracking phenomena.In addition, T-shaped shear connector structure of the present utility model is simple, simple for production, directly be welded on during use on steel beam flange plate, and shear connector top UNICOM, stressed coordination can be ensured, be conducive to equilibrium assignment shearing, prevent crucial section stress severe overweight and the less situation of other section stresses.Therefore, of the present utility modelly not only have that structure is simple, easy construction, good integrity advantage, and resistance to plucking is effective, and longitudinal shear resistance sexuality is strong, is particularly useful for hogging moment region.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment
See Fig. 1 ~ 3, the structure of a kind of open pore steel plate shear force of the present utility model, comprise the girder steel be made up of steel beam flange plate 1 and steel beam web plate 2, steel beam flange plate 1 is welded with T-shaped shear connector, described T-shaped shear connector comprises shear connector frange plate 4 and offers the shear connector web 5 of U-lag, and the thickness of described shear connector web 5 is 10mm, is highly 100mm, and the A/F of U-lag is 20mm, the spacing between U-lag is 200mm.U-lag on shear connector web 5 and steel beam flange plate 1 are formed one closed " door opening ", in this " door opening ", be provided with main muscle 6, and main muscle 6 is provided with closed stirrup 7.
During construction, first girder steel is laid by designing requirement, then on girder steel steel beam flange plate 1, T-shaped shear connector is welded, as shown in Figure 1, the shear connector web 5 of T-shaped shear connector is parallel with steel beam web plate 2 and shear connector web 5 is positioned at directly over steel beam web plate 2, the U-lag on shear connector web 5 and steel beam flange plate 1 is made to form closed " door opening ", and then adopt main muscle 6 through being somebody's turn to do " door opening ", and closed stirrup 7 is bundled on main muscle 6, finally set up template and concreting, make shaping after concrete slab 3 be connected as a whole with girder steel by T-shaped shear connector.
