Problems solved by technology
However, whether it is a hollow tube or a box, after it is applied to the floor as a permanent lightweight component, the formed floor includes reinforced concrete and lightweight components, and the lightweight components are wrapped in reinforced concrete. Force-transmitting components, especially when the size of lightweight components is large, the performance is more obvious. At the same time, the strength and stiffness of the corresponding cast-in-place floor slabs are relatively poor. Therefore, a new type of cast-in-place concrete hollow slab is developed , to improve the mechanical properties of the hollow plate, has been urgently needed

Embodiment Construction
[0056] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0057] As shown in the accompanying drawings, the present invention includes reinforced concrete 1 and lightweight components 2, and the lightweight components 2 are contained in the reinforced concrete 1, and is characterized in that the lightweight components 2 have at least one through pouring hole 3, and the concrete or steel bars Concrete is filled in the hole 3 to form a superimposed column or pier 4. At the same time, there is at least one groove 5 connected with the pouring hole 3 on the outer surface of the component, and concrete or reinforced concrete is filled in the groove 5 to form a concrete reinforcing rib or bar 6 . figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In each drawing, 1 is reinforced concrete, 2 is lightweight component, 3 is pouring hole, 4 is column or pier, 5 is groove, 6 is reinfo...

The in-situ cast hollow concrete board includes reinforced concrete and light member coated inside the reinforced concrete. The present invention features that the light member has at least one through hole, into which concrete or reinforced concrete is cast to constitute superposing column or pier, and at least one groove communicated with the through hole in the outer surface of the member, into which concrete or reinforced concrete is cast to constitute reinforcing rib or rib. These column or pier and reinforcing rib or rib improve greatly the mechanical performance of the hollow board and raise the strength and rigidity. The hollow board has also the features of simple structure, convenient construction, low cost, etc. and is suitable for hollow floor slab, roofing, base slab, wall and open web bridge of in-situ or pre-stressed reinforced concrete.
Description
(1) Technical field [0001] The invention relates to a cast-in-place concrete hollow slab. (2) Background technology [0002] Beamless floor is currently the most widely used floor structure for cast-in-place concrete floors. It has the advantages of fast construction speed, small structural height, flexible division of indoor areas, and no need for ceiling decoration. A hollow tube and box, the box is hollow or solid. For example, the patent No. ZL99232921.3, which the applicant applied for on March 10, 1999, is a utility model patent named "thin-walled tube for filling cast-in-place reinforced concrete", which consists of a hard thin-walled tube and two plugs. It is used as a lightweight component in beamless floors. Another example is Liang Jun of Shijiazhuang City, Hebei Province. The patent No. ZL00203695.9 applied for on February 23, 2000, the formwork used in the utility model patent named "combined concrete concealed rib floor cover", is described in No. 2 of the sp...
