Description
Technical field
The present invention relates to a kind of assembled two-way concrete slab truss floors, belong to construction engineering technical field.It can be extensive
Among all kinds of building structure.
Background technique
The speed of application of steel construction or prefabricated concrete structure is fast, in order to cooperate steel construction and prefabricated concrete structure
Progress, the form of the common industrialization floor of floor.There are commonly steel bar truss floor support plates, concrete floor slab (not band plate
Face reinforcing bar).
Steel bar truss floor support plate is that the steel bar stress in floor is welded into steel bar girder in factory, and galvanized steel plain sheet is in factory
Floor support plate is formed with steel bar truss welding.Type steel bar truss floor support plate is to be welded into the steel bar stress in floor in factory
Steel bar girder, galvanized steel plain sheet forms normalized template in factory's punching, or uses the conducts such as wood glue plate, bamboo slab rubber, plastic formwork
Template.Steel bar girder, template and connector are assembled into floor support plate by connector factory automation production and assembly, scene.Concrete
After pouring molding, template and connector are dismountable and reuse.Steel bar truss floor support plate and type steel bar truss floor support plate
Have many advantages, such as that rigidity is big, speed of application is fast, board bottom Forming Quality is good, is well used in engineering.
Current steel bar girder is mostly that the reinforcing bar that winds up, two lower edge reinforcing bars and two web member reinforcing bars are composed, and is in
Triangular truss.The advantages of English truss is to form spatial stability structure, the disadvantage is that lower edge reinforcing bar and web member reinforcing bar steel using amount
Greatly；Floorslab concrete pours smash before, the triangular reinforced bar truss stress performance in single direction is limited, under construction loads effect be easy
Form biggish downwarp；Under normal use load action, arrangement reinforcing bar, this part reinforcing bar are also required to steel bar girder vertical direction
Building-site is needed to be arranged, construction is inconvenient；Without the concrete floor slab of plate face reinforcing bar, the concrete floor of pre-erection
Rigidity is poor, is easy cracking, and when site operation needs to add plate face reinforcing bar.
Summary of the invention
In order to solve the existing problems, the invention proposes a kind of assembled two-way concrete slab truss floors.
Technical scheme is as follows:
The present invention includes two groups of plane steel bar girders and end template or bottom prefabricated concrete floor, every group of plane reinforcing bar purlin
