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 technology that existing reinforced concrete hollow floor (number of patent application 200420035588.6) adopts is with hollow prefabricated steel bar reinforced concrete, arrange in length and breadth and be placed on the bottom layer of the reinforcing steel concrete, fill out with steel concrete at the hollow prefabricated gap location of arranging in length and breadth and to become close rib, form cassette ceiling.This cassette ceiling has following deficiency: reinforcing bar, concrete feed consumption are many, great in vain, have increased the cost of floor, and the globality of floor, impervious bad.
Summary of the invention:
The object of the present invention is to provide a kind of good integrity, impermeability is good, feed consumption is few, floor is in light weight, cost is low, 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, this cassette ceiling comprises cast-in-place close rib, prefabricated sidewall, prefabricated panel, cast-in-place top board, prefabricated sidewall is assembled by the precast plate more than two or two, precast plate one end has projection, one end is fluted, hole is arranged on the projection, the projection of a precast plate is corresponding mutually with the groove of another piece precast plate, bolt or latch or reinforcing bar or steel wire pass hole and connect two or two above precast plates, are assembled into integral prefabricated sidewall.Integral side walls is made, transportation is inconvenient, and prefabricated sidewall adopts precast plate assembled, and precast plate can be produced in batches, easy construction has hole on the precast plate, during the prefabricated sidewall of assembly unit, in bolt or latch or reinforcing bar or steel wire insertion hole, connect precast plate, form prefabricated sidewall.
The projection of described precast plate is in the plane of precast plate or outside the plane.Precast plate various informative can be selected easy construction according to different designs and construction.
The job practices of this reinforced concrete hollow floor comprises the steps:
(1) precast plate is assembled into prefabricated sidewall;
(2) prop up template, colligation girt strip reinforcing bar is placed the prefabricated sidewall of being with hold item on template, prefabricated panel is placed on the hold item;
(3) between the prefabricated sidewall of arranging in length and breadth and the concreting of prefabricated panel top;
(4) treat that concrete reaches certain intensity after, remove hold item, prefabricated panel is placed on the brace rod of prefabricated sidewall bottom, cast-in-place close rib, prefabricated sidewall, prefabricated panel and cast-in-place top board form cavity;
(5) at prefabricated panel bottom whitewash mortar, form whole reinforced concrete hollow floor.
The prefabricated side wall upper part of cassette ceiling has the hole of settling hold item, be assembled into prefabricated sidewall with precast plate after, hold item is inserted in the hole.Hold item can be used for shelving prefabricated panel, and prefabricated panel places on the hold item, plays the effect of template.After treating that concrete reaches certain intensity, remove hold item, prefabricated panel is placed on the brace rod, brace rod can make prefabricated sidewall and prefabricated panel be connected to form integral body, can also strengthen the crack resistance of whole cassette ceiling.
Not tight for preventing that prefabricated sidewall is connected with cast-in-situ concrete, be provided with anchor rib at the precast plate top, after precast plate is assembled into prefabricated sidewall and concreting, anchor rib and cast-in-situ concrete bonding, build-in, the collaborative work between prefabricated sidewall and the cast-in-situ concrete is stronger.
Before the concreting, for preventing cast-in-situ concrete and prefabricated panel bonding, lay one deck separation layer on prefabricated panel top, it is too tight that separation layer can prevent that prefabricated panel and cast-in-place top board from boning, and simultaneously, hole is set on prefabricated panel, settle bolt in the hole, cast-in-situ concrete turns bolt after reaching certain intensity, utilizes bolt force that prefabricated panel is separated with cast-in-place top board.
