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 a bottom 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:
The present invention relates to the realm of building construction, specifically refer to a kind of reinforced concrete hollow floor.
Background technology:
Reinforced concrete cast-in-situ hollow floor plate than steel concrete solid floor feed consumption lack, floor is in light weight, the cassette ceiling that has is assemblied to form (number of patent application 200420035588.6) by the reinforced concrete prefabricated hollow unit of polylith, a plurality of precast hollow members are arranged in length and breadth, be placed on the bottom layer of the reinforcing steel concrete, filling out with steel concrete at the hollow unit gap location of arranging in length and breadth becomes close rib, form the assembly unit cassette ceiling, this cassette ceiling needs bottom board can form cassette ceiling, reinforcing bar, concrete feed consumption are many, Bai Chongda has increased the cost of floor.
A kind of floor spiced by steel reinforced concrete (publication number is CN1670324A), comprise reinforced concrete prefabricated board, close rib, during construction, a good template is arranged a plurality of reinforced concrete floors in length and breadth earlier, be placed on the template, put carriage or back-up block on the base plate, compress reinforced concrete prefabricated top board on carriage or the back-up block, filling out with steel concrete at the precast plate gap location of arranging in length and breadth becomes close rib, top board, base plate, close rib water and build up integral body, form floor spiced.The top board of this cassette ceiling, base plate, carriage are not tight with being connected of cast-in-place close rib, and the globality of floor is bad, and the floor end face is that prefabricated units and cast-in-place member are formed jointly, and the anti-permeability performance of floor is not good.
Summary of the invention:
The object of the present invention is to provide that a kind of feed consumption is few, floor is in light weight, cost is low, good integrity, impermeability is good, heat insulation property is good, the reinforced concrete hollow floor of easy construction.
The object of the present invention is achieved like this, a kind of reinforced concrete hollow floor, comprise cast-in-place close rib, prefabricated sidewall, prefabricated panel, cast-in-place top board, cassette ceiling forms cavity by prefabricated sidewall, prefabricated panel, cast-in-place top board and cast-in-place close rib, described prefabricated panel top is fluted, is filled with polyphenyl plate or light weight concrete construction or light material in the groove.
Vertical rib or cross rib are arranged in the groove of prefabricated panel or vertical rib and cross rib are arranged simultaneously, on rib, be coated with polyphenyl plate or light weight concrete construction or light material, like this, both alleviated the weight of prefabricated panel, also can guarantee the rigidity of prefabricated panel.
During construction, prop up good template earlier, colligation girt strip reinforcing bar on template, between the girt strip reinforcing bar, place prefabricated sidewall then, prefabricated side wall upper part has hold item, prefabricated panel is placed on the hold item on the prefabricated sidewall, on prefabricated panel, cover one deck separation layer, between the prefabricated sidewall of arranging in length and breadth, reach prefabricated panel top concreting then, form cast-in-place close rib and cast-in-place top board, after treating that concrete reaches certain intensity, stripping, hold item is placed on prefabricated panel on the bottom projection of prefabricated sidewall prefabricated sidewall, prefabricated panel, cast-in-place top board and cast-in-place close rib form cavity, whitewash mortar under prefabricated panel forms whole cassette ceiling.Owing to be filled with polyphenyl plate or light weight concrete construction or light material in the groove of prefabricated panel, alleviated the weight of prefabricated panel, it is safer, convenient to construct, and insulation, the thermal insulation of floor are better.
Before prefabricated panel top pouring cast-in-situ concrete, the separation layer on the prefabricated panel can prevent cast-in-place top board and prefabricated panel bonding, and like this, prefabricated panel is easy to separate with cast-in-place top board.Top projection and bottom projection are arranged on the prefabricated sidewall, and the top projection can make prefabricated panel end and prefabricated sidewall side plate that certain distance is arranged, and like this, has guaranteed that prefabricated panel can not be stuck in the process that is placed into prefabricated sidewall bottom projection; The bottom projection can be used to support prefabricated panel, makes prefabricated sidewall and prefabricated panel form integral body; Prefabricated top side wall is provided with anchor rib simultaneously, and behind the concreting, anchor rib and cast-in-situ concrete bonding, build-in make that the collaborative work between prefabricated sidewall and the cast-in-situ concrete is stronger, and stress performance, the globality of cassette ceiling are better.
