Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing.

[0020] The invention is attached Figure 1-9 As shown, a reinforced concrete hollow floor slab includes cast-in-place dense ribs 1, prefabricated side walls 2, prefabricated bottom slab 3, and cast-in-place roof 4. The hollow floor slab consists of prefabricated side walls 2, prefabricated bottom The dense ribs 1 form a cavity 5, and the prefabricated floor 3 has a groove 16 on the top, and the groove 16 is filled with a polystyrene board 17 or lightweight concrete or lightweight materials. figure 1 It is a schematic diagram of filling the polystyrene board 17 in the groove 16 of the prefabricated base plate 3 .

[0021] There are longitudinal ribs or transverse ribs or both longitudinal ribs and transverse ribs in the groove 16 of the prefabricated floor 3, and polystyrene boards 17 or lightweight concrete or lightweight materials are covered on the ribs 13, so that the w...

Abstract

The invention discloses a reinforced concrete hollow floor which comprises an in-situ rib (1), a precast side wall (2), a precast bottom plate (3) and an in-situ top plate (4), wherein the top of the precast bottom plate (3) is provided with a groove (16), and the inside of the groove (16) is filled with polystyrene plates, lightweight concrete or lightweight materials (17). The method for constructing the hollow floor comprises the following steps of: mounting a template (11), binding ribbed steel bars (12), and placing the precast side wall (2); placing the precast bottom plate (3) on a resting component (9) on the precast side wall (2), then casting concrete, after the concrete reaches a certain strength, removing the resting component (9), and placing the precast bottom plate (3) on abottom convex block (7) of the precast side wall (2); and painting mortar (15) below the precast bottom plate (3), thereby forming an integral hollow floor. The hollow floor disclosed by the invention is good in stressing property, integrity and impermeability; and because the inside of the precast bottom plate is filled with polystyrene plates, lightweight concrete or lightweight materials, the hollow floor is light in weight, low in cost, good in thermal insulation performance and convenient in construction.

Description

Technical field: [0001] The invention relates to the field of building construction, in particular to a reinforced concrete hollow floor slab. Background technique: [0002] Reinforced concrete cast-in-place hollow slabs consume less material than reinforced concrete solid slabs, and the slabs are lighter in weight. Some hollow slabs are assembled from multiple reinforced concrete prefabricated hollow components (patent application number 200420035588.6). On the bottom reinforced concrete, the gaps between the vertically and horizontally arranged hollow members are filled with reinforced concrete to form dense ribs to form an assembled hollow floor slab. This kind of hollow floor slab needs to be poured with a bottom slab to form a hollow slab. the cost of the floor. [0003] A reinforced concrete assembled floor slab (the publication number is CN1670324A), including reinforced concrete prefabricated slabs and dense ribs. During construction, the formwork is first supported...
