Embodiment 1
[0033] Such as figure 1 As shown, the fasting small ribbed floor of the present invention includes a solid densely ribbed beam 1 with reinforced concrete, a panel 2 with reinforced concrete, a composite thin-walled box 3, and a thin bottom plate 4 integrated at the lower end of the box 3 , the thin bottom plate 4 is a board formed by diamond-shaped steel wire mesh or other shaped steel wire mesh, alkali-resistant glass fiber cloth or alkali-resistant glass fiber cloth or plastic mesh cloth and cement mortar 5, when the reinforced concrete hollow ribbed floor When cast-in-place, the bottom plate of the composite thin-walled box 3 and the reinforcing material 5, under the action of the vibrator, make the cement mortar infiltrate into the bottom of the composite thin-walled box, and the bottom panel of the composite thin-walled box 3 and the infiltrated cement mortar Organically combined to form a thin bottom plate 4 that closes the cavities of the ribs. And because the newly fo...
Embodiment 2
[0036] Such as figure 2 As shown, on the same basis as Embodiment 1, the difference of this embodiment is that the water chestnut of the composite thin-walled box body 3 is an inverted water chestnut (such as Pic 4-1 , 4-2 Shown), the book base plate 4 that is arranged on casing 3 lower ends is segmental type, only is provided with by this type book base plate 4 at the lower end corresponding position of each casing 3, saves material again while reaching the object of the present invention.
Embodiment 3
[0038] Such as image 3 As shown, on the same basis as that of Embodiment 1, the difference of this embodiment is that the box body 3 is an integral box body, and the water chestnut of the composite thin-walled box body is an inverted water chestnut, as Figure 4-3 shown.
[0039] The manufacturing method of the above-mentioned embodiment mainly includes the following steps
[0040] a) Beams, columns and small ribbed steel bars laid and bound on the floor formwork;
[0041] b) At the same time, lay diamond-shaped or other shaped steel wire mesh and other reinforcing materials for the bottom panel;
[0042] c) Place and fix the manufactured composite thin-walled box;
[0043] d) Binding panel reinforcement;
[0044] e) When the buoyancy is generated, use 12# iron wire to tie the steel bar at the bottom of the densely ribbed beam through the formwork and tie it to the support rod, or use 12# iron wire to tie the support rod, penetrate the formwork, and tie it to the bottom s...
