Problems solved by technology

[0002] The cast-in-place concrete hollow floor that is popularized and applied at present is developed on the basis of traditional prefabricated hollow slab and solid beamless floor. I invented the ZL98231113.3 invention patent "concrete thin-walled cylinder component" in 1998, which solved the problem of The technical problems of the non-centering hole-forming process of the cast-in-place hollow floor cover overcome the problems of poor overall structural performance of the building caused by the prefabricated hollow-core slab, the floor is easy to crack, the span is small, and the problem of low bearing capacity is solved. The beamless floor uses a large amount of reinforced concrete, the building itself is heavy, the foundation cost is high, and the cost is increased.
Although the cast-in-place concrete hollow floor has the above-mentioned advantages, it also has unclear two-way force design, and the hollow rate of the floor is low (generally 20%-40%). Considering the problems of "concrete thin-walled cylinder components" single component fixing, single component anti-floating and overall floor anti-floating, there are certain limitations in large-scale use in buildings

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...

Abstract

The hollow floor slab includes column, solid belt, solid reinforced beam with dense ribs, reinforced facing board, and composite box with lower thin bottom board. The production process includes: a) laying and tying reinforcing steel bar in the floor slab formwork; b) laying the steel wire net and other reinforcing material; c) setting and fixing made composite thin box; d) tying reinforcing steel bar for the facing board; e) fixing reinforcing bars with iron wire; and f) embedding prefabricated pipeline inside the facing board and the dense ribs. The present invention may produce flat sealed floor slab cavity with dense ribs in once deposition.
