Problems solved by technology

In the preparation process, it takes a lot of time to lay out the bottom formwork to form the construction work surface, and this part of the construction consumes a lot of manpower and time
In addition, the on-site reinforcement mesh binding also requires manual connection of the horizontal and vertical reinforcement bars with tie wires. The workload is heavy and cumbersome, which not only consumes a lot of manpower, but also seriously affects the progress of the project.
In the concrete cast-in-place slab structure with a large load, in order to increase the bending resistance of the structure, it is often necessary to equip steel bars with a larger diameter during design, resulting in an increase in cost

Embodiment 1

[0044] see Figure 1-3 as well as Figure 8 As shown, the rib frame concrete cast-in-situ slab provided by the embodiment of the present invention includes a rib frame 1 , a bottom plate 2 and concrete 3 .

[0045] see figure 1 and figure 2 As shown, the rib frame 1 includes a plurality of upper ribs 13, a plurality of lower ribs 11 and a plurality of connecting ribs 12, wherein:

[0046] see Figure 6 As shown, the lower side of each upper rib 13 is provided with a plurality of upper interlocking grooves 131 at intervals along the length direction of the upper rib 13 . see Figure 4 As shown, the upper side of each lower rib 11 is provided with a plurality of lower interlocking grooves 111 at intervals along the length direction of the lower rib 11 . see Figure 5 As shown, the upper side of each connecting rib 12 is provided with a plurality of upper connecting grooves 122 at intervals along the length direction of the connecting rib 12 , and the lower side is provid...

Embodiment 2

[0066] The second embodiment is basically the same as the first embodiment, and the similarities will not be repeated. The difference lies in: see Figure 9 As shown, at least one flange 151 is provided on the edge of the connecting channel 15 , and the flange 151 extends into any pouring unit 14 located at both ends of the connecting channel 151 . In this embodiment, the flange 151 can effectively increase the connection strength between the concrete 3 and the rib frame 1 , and further improve the bonding strength of the rib frame concrete cast-in-place slab.

[0067] Preferably, a plurality of flanges 151 are provided around the connecting channel at the edge of the connecting channel 15, wherein a part of the flanges 151 extend into one of the casting units 14 at both ends of the connecting channel 15, and the other part of the flanges 151 extend into the two ends of the connecting channel 15. Another pouring unit 14. Further preferably, a plurality of flanges 151 extend i...

Embodiment 3

[0070] On the basis of any one of the embodiments in Embodiment 1 or Embodiment 2, this embodiment 3 provides a rib-skeleton concrete cast-in-place slab with a connecting part 4, which facilitates the connection between adjacent rib-slab skeleton concrete cast-in-situ slabs. Connection or connection between rib-framed concrete cast-in-place slabs and load-bearing beams. In one embodiment, see Figure 10 and Figure 11 As shown, a plurality of connecting parts 4 are arranged on the side of the rib-frame concrete cast-in-place slab, and after pouring concrete, at least a part of each connecting part 4 protrudes from the rib-plate skeleton concrete cast-in-place slab.

[0071] In some embodiments, the connection part 4 can be a structure such as a straight steel bar, a U-shaped steel bar, a straight-line plate or a U-shaped plate, and its uniform end is fixedly connected to the rib frame 1, and the other end protrudes from the rib frame to cast in-situ concrete. plate. Prefera...

Abstract

The invention relates to the technical field of cast-in-place concrete slabs, in particular to a cast-in-place concrete slab with a rib plate skeleton. The concrete cast-in-place slab includes a rib frame, a bottom plate and concrete, wherein the rib frame includes a plurality of interlocking and staggered upper ribs, connecting ribs and lower ribs to form multiple pouring units, and adjacent pouring There is a connecting channel between the units to communicate with two adjacent pouring units, the lower end of the rib frame is fixed to the bottom plate, concrete fills each pouring unit, covers the rib frame and is fixed to the bottom plate. The rib frame concrete cast-in-place slab, the bottom plate can be used as the bottom form, which reduces the time for laying the bottom form, saves manpower and time, and forms the rib frame by using the rib plate interlocking installation, which is convenient and quick to install. The connecting channels of the adjacent pouring units are connected, and the rib frame is fixedly connected with the bottom plate, so that the entire rib frame concrete cast-in-place slab has a high bending bearing capacity.

Description

technical field [0001] The invention relates to the technical field of cast-in-place concrete slabs, in particular to a cast-in-place concrete slab with a rib plate skeleton. Background technique [0002] In civil engineering, traditional cast-in-place slabs consist of steel and concrete. During construction, the wooden formwork at the bottom is erected first, then steel bars are laid and bound on the working surface formed by the wooden formwork, and finally concrete is poured to form a concrete cast-in-place slab. In the preparation process, it takes a lot of time to lay out the bottom formwork to form the construction work surface, and this part of the construction consumes a lot of manpower and time. In addition, on-site binding of steel mesh also requires manual connection of horizontal and vertical steel bars with tie wires. The workload is heavy and cumbersome, which not only consumes a lot of manpower, but also seriously affects the progress of the project. In the ...
