Description
Technical field
The utility model belongs to building aseismicity reinforcing technique field, is specifically related to a kind of prefabricated hollow floor antidetonation fall arrest girth member.
Background technology
In Wenchuan earthquake, a large amount of prefabricated hollow floors break away from bearing and fall, and have caused great casualties and property loss.A large amount of analysis reports are all thought: falling of precast floor slab is one of house main reason of caving in earthquake.Although the construction bureau of present many local governments has all required floor to use cast-in-place plate instead, can not reconstruct by complete removal for having built up the precast floor slab building in a large number, thereby the reinforcing of the antidetonation fall arrest of precast floor slab is the major tasks in the present seismic hardening.Solution commonly used at present is to lay steel mesh reinforcement to remake the thick pea gravel concreten whole casting layer of 30～40mm on flooring, but is difficult to before the enforcement of this method the leveling layer of original flooring is cut fully, so must increase dead load 0.75KN/m
2～1.0KN/m
2And the supporting capacity of the old building that will reinforce own is just not enough, and increasing this imposed load more obviously has adverse effect to structural safety.And dead load increase back geological process also strengthens.In addition, watering the reinforced mesh whole casting layer after is difficult to penetrate body of wall and whole architectural plane is fused.Just play mass action in single house interior, this can not solve the root problem that floor falls.
Summary of the invention
The purpose of this utility model is to provide a kind of prefabricated hollow floor antidetonation fall arrest girth member.
The prefabricated hollow floor antidetonation fall arrest girth member that the utility model proposes, by porous preforming plate 2, reinforced concrete bar 3, connector 4, stretching screw 5, foam plug 6 and quadrature constitute to pull bar 10, porous preforming plate 2 is positioned at collar tie beam 8 both sides of steel concrete ledger beam 1 or body of wall 7, wherein: vertically have groove in the porous preforming plate 2, be provided with reinforced concrete bar 3 in the groove, be embedded with connector 4 in the reinforced concrete bar 3, two connectors connect by stretching screw 5, stretching screw 5 one ends connect the connector 4 of the porous preforming plate 2 that is positioned at a side, the other end passes two blocks of porous preforming plates 2 and steel concrete ledger beam 1 or body of wall 7, connects the connector 4 of the porous preforming plate 2 that is positioned at opposite side; Reinforced concrete bar 3 two ends and porous preforming plate 2 junctions are provided with foam plug 6, connect to pull bar 10 by quadrature between the connector in same porous preforming plate 2, and quadrature extends in the porous preforming plate 2 of both sides to pull bar 10 simultaneously.
In the utility model, when porous preforming plate 2 was connected with body of wall 7, stretching screw 5 was provided with banking stop 9 with body of wall 7 junctions.
The utility model has the advantages that:
(1) increases dead load hardly, so do not increase geological process;
(2) solved floor and under geological process, broken away from the problem that bearing falls drawing by floor;
(3) can also by be orthogonal to floor length to horizontal drawknot, increase between the floor that antiskid moves ability in the plane, reduce in the floor level changing of the relative positions and be out of shape;
(4) bolt increases the ability of floor opposing vertical load simultaneously as seat shoulder bar;
(5) the stabilization works amount is little, reinforces expensive few.

The specific embodiment
The utility model is described in further detail in conjunction with the accompanying drawings below by embodiment.
Embodiment 1: the utility model is vertically to hole in the groove position of the prefabricated porous plate 2 of the both sides correspondence of steel concrete ledger beam 1 (body of wall 7), in the drill hole groove, pour into the reinforced concrete bar 3 of certain-length, and built-in connection 4 therein, cross over steel concrete ledger beam 1 or body of wall 7 then, connect with the connector 4 of bolt both sides, and, with cement mortar groove is filled and led up at last stretching screw 5 tensionings (screw rod is installed in the groove in h * b=30 * 40 cross sections of opening on original leveling layer).Wherein water the cement mortar of smashing reinforced concrete bar 3 and filling out groove and all use the microdilatancy material.Every is fallen precast plate 2 two ends in advance and respectively links to each other with two blocks of prefabricated porous plates 2 of two stretching screws 5 and other.Tie point 4 is located at 1/4 span place, both can be anti-fall, also can increase the ability of floor opposing vertical load.
