It is used for for a kind of component in steel construction and cast-in-place concrete structure.
In recent years, country carries forward vigorously building industrialization, the development of A clear guidance prefabrication.Laminated floor slab is made
For the important feature component in the structural system, there is very high industrialization degree, be a kind of green building structure mould
Formula, it is the developing direction of China's building industrialization.Laminated floor slab is formed by stacking by pre-erection and cast-in-place part, and it possesses prefabricated
The characteristics of assembled industrialization degree height and full cast-in-place structural good integrity.At present, conventional laminated floor slab is steel bar girder building
Board, due to prefabricated board rough surface, and there is truss bars stretching, the bonding of after-pouring concrete folding layer can be fully ensured that
Power transmission.But its cost is higher, close to 2 times of common profiled sheet, the processing of steel bar girder needs Special Equipment, prefabricated portion
There is the defects of complex process in the reinforcing bar colligation positioning divided, and steel bar truss floor support plate in general is left in 5m without support spacing
The right side, for the bigger building of span, it is still desirable to support scaffolding, limit its application to a certain extent.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of embedded laminated floor slab of T-steel, this laminated floor slab
Overcome conventional steel bar truss floor support plate processing and fabricating complexity, using the defects of span is smaller, bearing capacity is not high, easy to crack, have
Effect improves bending rigidity and bearing capacity, is advantageous to the industrialized production of floor construction.
In order to solve the above technical problems, the embedded laminated floor slab of T-steel of the present invention is including between some directions along plate face span
T-steel beam, bottom every arrangement reinforced mesh, top reinforced mesh, the concrete prefabricated layer in bottom and top coagulation in length and breadth in length and breadth
Native in-situ layer, the web lower edge interval of the T-steel beam open up some trapezoidal notches, and reinforced mesh is embedded in length and breadth for the bottom
Some trapezoidal notches, reinforced mesh is layed in the flange surfaces of the T-steel beam in length and breadth on the top, and the bottom is in length and breadth
The part web of reinforced mesh and T-steel beam is located in the concrete prefabricated layer in the bottom, the other part abdomen of the T-steel beam
Reinforced mesh is located in the top concrete cast-in-situ layer in length and breadth for plate, the edge of a wing and top.
Further, the reinforcing bar of bottom reinforced mesh in length and breadth is arranged in the corner of the trapezoidal notch.
Further, the web of the T-steel beam is set perpendicular to plate face.
Because the embedded laminated floor slab of T-steel of the present invention employs above-mentioned technical proposal, i.e., this laminated floor slab along plate face across
The degree spaced apart T-steel web lower edge interval in direction opens up some trapezoidal notches, if reinforced mesh is embedded in length and breadth for bottom
Dry trapezoidal notch, reinforced mesh is layed in the flange surfaces of T-steel beam in length and breadth on top, bottom reinforced mesh and T-steel beam in length and breadth
Part web be located in the concrete prefabricated layer in bottom, other part web, the edge of a wing and the top of T-steel beam reinforced mesh in length and breadth
In the concrete cast-in-situ layer of top.This laminated floor slab overcome conventional steel bar truss floor support plate processing and fabricating it is complicated, using across
The defects of degree is smaller, bearing capacity is not high, easy to crack, effectively improves bending rigidity and bearing capacity, is advantageous to the industry of floor construction
Metaplasia is produced.
