Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples：The floor of the prior art needs as needed
Shape is pointedly prefabricated or only single structure size is integrally connected across on the beam of both sides, cannot completely match somebody with somebody in building structure
During conjunction, installation and construction are all relatively complicated.The utility model tries hard to solve the problems, such as this.
The precast splice type floor as shown in Fig. 1,2, the whole on-gauge plate by rectangular module of floor connect in same plane
Continuous to be spliced, the length of side of on-gauge plate is 0.3 ~ 2.4m, can set the on-gauge plate of different size, select as needed.
The on-gauge plate lower floor is steel frame 5, and the top surface of steel frame is equipped with concrete layer 1, the side face edge of concrete layer
Edge inside contracts 25 ~ 150mm with respect to the side of steel frame.Bar-mat reinforcement 2, reinforcing bar are parallelly embedded with concrete layer in concrete layer
Net 2 stretches out 50 ~ 250mm of side of concrete layer.In order to the bar connecting between adjacent modular on-gauge plate.
The lateral location of concrete layer is stretched out in bar-mat reinforcement, concrete layer is equipped with the link slot of multiple 40 ~ 125mm that concave
9.It is equally easy for the bar connecting between adjacent modular plate and larger connection space is provided.
The steel frame 5 surrounds hollow entirety for four sides channel steel, and the web 6 of channel steel is vertical with concrete layer 1, notch to
Interior, the wing plate 8 of channel steel top surface is fixedly connected with concrete layer；It is equipped with to fix with steel frame in the range of concrete layer covering and connect
The peg 4 connect.To enhance the attachment force between steel frame and concrete layer.
The web 6 of channel steel is equipped with bolt hole 10, and installation or standard are connected with building girder or column from side for floor to be whole
Splicing between plate.When being connected between adjacent modular plate, the web 6 of channel steel contacts directly, and bolt hole aligned in position can be direct
