Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-4 is please referred to, the present invention is the following technical schemes are provided: a kind of gasbag-type for building structure floor slab construction seam
Concrete blocking apparatus, including including construction joint air bag 1, the construction joint air bag 1 is internally provided with air bag liner 101, institute
The outer wall for stating air bag liner 101 is provided with the outer gallbladder 102 of air bag, and the inflating catheter 103 for inflation is through gallbladder 102 outside the air bag
One end be accommodated in the inside of the air bag liner 101；The horizontally arranged of construction joint air bag 1 has multiple horizontal fixed drag hooks
501, the unilateral vertical plane of construction joint air bag 1 is provided with multiple mobile fixed drag hooks 502；The outer gallbladder 102 of air bag is evenly equipped with multiple circles
Bore bulge-structure.
Further, the thickness of the outer gallbladder 102 of air bag is not less than 3mm, and conic convex structure and the outer gallbladder 102 of air bag are all made of
Compounded rubber material, so that conic convex structure and the outer gallbladder 102 of air bag have puncture resistance and flexibility simultaneously.Conic convex
Structure can prevent the outer thin place of gallbladder 102 of air bag directly frayed, and outer surface generally has the compounded rubber material of puncture resistance
Matter, and there is ductility, it can be when construction joint air bag 1 be constructed and is inflated, after bulk expansion, the outer gallbladder 102 of air bag does not rupture.
Further, upper row longitudinal reinforcement 3 of the diameter not less than steel mesh on concrete floor after air bag liner 101 is inflated
With the height of lower row's longitudinal reinforcement 4, the length is 8m-10m.
As example: the filling construction of construction joint air bag 1 gap after inflation carries out interception barrier to concrete slurry, subtracts
Few concrete waste, while construction joint Forming Quality is good, reduces the secondary cost for picking chisel.
The present invention also provides a kind of uses of gasbag-type concrete blocking apparatus for building structure floor slab construction seam
Method, which comprises the following steps:
S1, first install floor slab bottoms template 7, steel mesh be set in floor slab bottoms template 7, the opposite sides of construction joint with
Upper row's longitudinal reinforcement 3 of steel mesh and lower row's longitudinal reinforcement 4 are corresponding, and construction joint air bag 1 runs through steel at the lamination of steel mesh
Gap between upper row's longitudinal reinforcement 3 of muscle net and lower row's longitudinal reinforcement 4, and the both ends of construction joint air bag 1 are connected using iron wire
It is fixed on reinforcing bar；Meanwhile setting intercepts steel wire 2 at beam slab；
S2, fixed supervisor 8 is equipped on upper row's longitudinal reinforcement 3, the fixed drag hook 501 of the level of construction joint air bag 1, which is hung, to be closed
Corresponding fixation is responsible on 8, and the both ends of the mobile fixed drag hook 502 of construction joint air bag 1, which hang to close, is responsible for 8 under in corresponding fixation
It arranges on longitudinal reinforcement 4；
After S3, the both ends for completing construction joint air bag 1 and outside are fixed, filled by inflating catheter 103 to air bag liner 101
Gas, air bag 102 forced expansion deformation of outer gallbladder, the gap between the row's of being crowded with longitudinal reinforcement 3 and lower row's longitudinal reinforcement 4；
S4, casting area is poured and is cooled and shaped, after to be formed, by the gas in air bag liner 101 by filling
103 outlet of airway restores the original shape of the construction joint air bag 1, removes fixed upper row's longitudinal reinforcement 3, lower row longitudinal direction
Reinforcing bar 4 and iron wire are extracted construction joint air bag 1 out by reinforcing bar mesh, i.e. the intercept process of completion mixed mud floor slab construction seam.
Further, 1 outer wall of construction joint air bag is equal respectively close to the end face of upper row's longitudinal reinforcement 3 and lower row's longitudinal reinforcement 4
Matcoveredn is set and intercepts sheet rubber 6, protective layer intercepts sheet rubber 6 will 3 He of the row's of wrapping longitudinal reinforcement by compressional deformation
Lower row's longitudinal reinforcement 4, protective layer intercept sheet rubber 6 and play to concrete interception function.
Further, horizontal fixed drag hook 501 and mobile fixed drag hook 502 are in the interval of 500mm on fixed supervisor 8
Setting.
In summary: the invention by utilize construction joint air bag 1 itself flexible concertina filling capacity, gassy or
Gap (the present embodiment is filled using gas) after liquid between the row's of being crowded with longitudinal reinforcement 3 and lower row's longitudinal reinforcement 4, construction joint
After concrete setting, by discharge gas or liquid, directly go out to extract out from steel wire, construction reinforcement is convenient and efficient, has saved people
Between working hour and material cost, guarantee quality are environmentally protective.
Specifically, the row's of being equipped with longitudinal reinforcement 3 and lower row's longitudinal reinforcement 4 at construction joint, steel wire 2 is mounted at beam slab
Side to casting area forms baffling device；Steel wire 2, upper row's longitudinal reinforcement 3 and lower row's longitudinal reinforcement 4 can be using normal
General improving bud grafting is fixed, and horizontally disposed fixed supervisor 8 is laid on upper row's longitudinal reinforcement 3.The outer wall of fixed supervisor 8 is hitched
Equipped with multiple moveable horizontal fixed drag hooks 501 and moveable vertically fixed drag hook 502, level is fixed drag hook 501 and is erected
To the fixed mating arrangement of drag hook 502, the fixed drag hook 501 of level, which is fixed, arranges longitudinal reinforcement 3, under vertical fixed drag hook 502 is fixed
Arrange longitudinal reinforcement 4.Spacing distance is 500mm between the horizontal fixed drag hook 501 of adjacent two or mobile fixed drag hook 502, left
The mobile fixed drag hook 502 and 1 lateral wall interval of construction joint air bag that the fixed drag hook 501 of the level moved right and left and right move up and down
It is fixed.
Meanwhile construction joint air bag 1 is controlled by the fixed drag hook 501 of sliding level and is moved left and right in 2 interlayer of steel mesh；It is logical
It crosses mobile fixed drag hook 502 and controls the left and right multi-direction movement up and down in 2 interlayer of steel mesh of construction joint air bag 1.
It is worth noting that, the end face of construction joint air bag 1, which is embedded with the protective layer with deformation nature, intercepts sheet rubber 6,
Construction joint air bag 1 can be crowded with the gap between two layers of steel mesh 2, while construction joint air bag 1 leans on the protection up and down of concrete side
Layer intercept sheet rubber 6 by squeeze will the row's of wrapping longitudinal reinforcement 3 and lower row's longitudinal reinforcement 4, the sheet rubber between reinforcing bar rises
To concrete interception function, concrete and rebar mixed-forming is prevented to be difficult to remove, while can be by lower protective layer on reinforcing bar
Gap intercepts, and reduces the loss of concrete slurry, reduces the secondary of concrete construction joint facade and picks chisel.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
