The die carrier connecting block 5 and the die plate connecting block 6 are connected with the bottom die plate 1 into a whole from bottom to top through countersunk screws 10 (preferably plastic pieces).
The two ends of the top beam 3 are plugged, the cross section of the top beam 3 is an isosceles trapezoid structure with an open top, the length of the upper bottom of the isosceles trapezoid structure is smaller than that of the lower bottom, the left waist top of the isosceles trapezoid structure is bent right and then downwards to form a first left L-shaped reinforcing strip plate 11, the right waist top of the isosceles trapezoid structure is bent left and then downwards to form a first right L-shaped reinforcing strip plate 12, and a gap for pouring concrete into the isosceles trapezoid structure is reserved between the right side of the first left L-shaped reinforcing strip plate 11 and the left side of the first right L-shaped reinforcing strip plate 12.
Embodiment two: as shown in fig. 3, the difference between this embodiment and the first embodiment is that the cross section of the top beam 3 is an isosceles trapezoid structure with an open bottom, the left waist bottom of the isosceles trapezoid structure is bent first to the right and then upwards to form a second left L-shaped reinforcing slat 13, and the right waist bottom of the isosceles trapezoid structure is bent first to the left and then upwards to form a second right L-shaped reinforcing slat 14.

Fifth embodiment: this embodiment differs from the first embodiment in that the top beam 3 is a steel bar, a round steel pipe or a rectangular steel pipe. When the top beam 3 is a steel bar, concrete or mortar does not need to be poured. When the top beam 3 adopts a round steel pipe or a rectangular steel pipe, the lower end of the steel pipe is blocked, grout or concrete enters through a buckle at the upper end of the steel pipe, grouting operation is directly carried out, and the upper end opening of the steel pipe is blocked after completion.

The L-shaped reinforcing strip plate not only plays a role in enhancing the strength of the top beam 3, but also plays a role in limiting concrete or mortar poured in the U-shaped structure or the isosceles trapezoid structure, and further enhances the strength of connection with the concrete. The length of the upper bottom of the isosceles trapezoid structure is smaller than that of the lower bottom, so that concrete poured inside and the top beam 3 are easier to form a whole when bearing pressure, and the compression resistance of the top beam 3 is enhanced. The whole compressive strength of the steel bar truss 2 can be improved by pouring concrete or mortar in advance in the top beam 3, so that the span of the floor support plate is larger.

Concrete is poured on the upper surface of the bottom template 1, and the top beam 3 is also poured in the concrete, so that a cast-in-place floor carrier plate is formed after solidification. The floor form 1 is used as a ceiling without dismantling. Because the application adopts the cast-in-place, compared with the laminated floor slab (cast-in-place once in factory), the application has fewer working procedures, better integrity and larger bearing strength, and the weight of the hoisted component is lighter during the cast-in-place operation.
