Problems solved by technology

When the thickness of the hollow slab is less than 350mm, binding hidden beam reinforcement (stirrups) in the slab will add a lot of unnecessary workload to the construction; when the slab is a two-way slab, if there are hidden beam reinforcements (stirrups) ), the construction is especially troublesome

Embodiment Construction

[0037] The present invention is realized in the following manner:

[0038] exist figure 1 Among them, the thickness of the hollow slab is 180-350mm. The hollow slab includes the upper steel bar (1), the lower steel bar (2), concrete (3), and the combined module (4). The combined module (4) is located between the upper steel bar (1) and the Between the steel bars (2) of the lower layer, they are permanently buried in the concrete (3). When the span of the hollow slab is large or the load is large, prestressed tendons (5) can be arranged in the inter-block ribs (9).

[0039] exist figure 2 , image 3 In the shown embodiment, the combined module (4) is formed by combining rod-shaped fillers (6) and grids (7). In each combined module (4), between adjacent rod-shaped fillers (6) An inner rib (8) is provided, the width of the inner rib (8) is 40-100 mm, and the rod-shaped filler (6) is solid or hollow.

[0040] exist Figure 4 In the shown embodiment, inter-block ribs (9) are pr...

Abstract

The invention discloses a hollow floor with permanent composite modules and its implementation method. The hollow floor includes upper steel bars, lower steel bars, concrete and composite modules. The composite modules are located between the upper steel bars and the lower layer steel bars. Permanently buried in the concrete, place the composite module in the specified position according to the shear force transmission direction, the orientation of the composite module is consistent with the shear force transmission direction in the slab where it is located, and the orientation of the composite module is the direction of the combination In the length direction of the rod-shaped filler in the module, the present invention is suitable for one-way slabs and two-way slabs. The hollow slabs of the present invention are light in weight, good in sound insulation and heat insulation, and have better structural reliability, shock resistance and crack resistance. Good, convenient construction, good economy and applicability.

Description

(1) Technical field [0001] The invention relates to a floor system in a reinforced concrete structure, in particular to a permanent filler in a cast-in-place reinforced concrete hollow floor and a construction method thereof. (2) Background technology [0002] In the field of construction, with the increasing number of long-span concrete structures, more and more floor slabs adopt hollow-core floor structure technology, and many innovative technologies have also emerged in the field of hollow-core floors. The patented technology "Thin-walled tube-filled cast-in-place concrete hollow floor" (ZL99232922.1) discloses a technology for the application of thin-walled tubes in cast-in-place concrete; "A reinforced concrete tubular hollow floor" (ZL01140463.9) , "A reinforced concrete tubular lightweight floor slab" (ZL01140466.3) and "A kind of cast-in-place concrete hollow slab" (application number 200510067584.5) continue to innovate the application of tubular fillers in hollow f...
