Background technique
Nowadays, prefabricated assembled concrete structure is a kind of common building structure, in recent years, in China, prefabrication and assembly construction
Formula concrete structure has become the principal mode of new building, and will play an increasingly important role.
For prefabricated assembled concrete component, the most weak place of structural behaviour is the faying face of component.Many structures
Before distress in concrete appearance, faying face just cracks.
Existing prefabricated assembled concrete component faying face almost all is mill finished form, prefabricated assembled concrete structure
Cohesive force between part and rear pouring concrete is insufficient.
Existing makes the roughened technology of prefabricated assembled concrete component faying face, using traditional bellows or
The template of person's PVC material causes installation, transport all inconvenient since volume is big, self weight is larger, and bellows place after cannot take
Out, and concrete joint surface by bellows carrys out transfer bond, and adhesion strength is relatively low.

It is detachably connected.In the present embodiment, one end of membrane body 10 is threadedly coupled by the way that threaded fittings are arranged with fixed plate 20, the other end
It is Nian Jie with fixed plate 20 by seccotine.
The application method of gas-filled formwork 100 applied to prefabricated assembled concrete component is used for by using gas-filled formwork
100 construct special-shaped penetration type joint face in prefabricated assembled concrete component inside.As shown in Fig. 2, including the following steps:
The gas-filled formwork C10 of unaerated is passed through 40 two end side panels of forming panel before casting concrete component by step S1
42 reserved through hole；
Two fixed plates 20 are connected in the two end side panels 42 of forming panel 40 by step S2, at this point, membrane body 10 is solid
Fixed is connected across between two blocks of side plates 42.In the present embodiment, fixed plate 20 is to be threadedly coupled with the connection type of side plate 42；
10 gassy of membrane body is obtained the membrane body 10 with certain rigidity by step S3；
Step S4, the casting concrete component in forming panel 40, membrane body 10 and pouring molding with certain rigidity
Contact surface inside concrete component is the penetration type joint face of concrete component；
Step S5 connects 40 both ends of forming panel to concrete component initial set, that is, when concrete component loses plasticity
The fixed plate 20 connect is removed, and in the present embodiment, removing fixed plate 20 is specially to release the company of fixed plate 20 and forming panel 40
It connects, one piece of fixed plate 20 is removed from gas-filled formwork 100；And
Step S6 deflates membrane body 10, and soft membrane body 10 is extracted out from forming panel 40.Membrane body 10 is from forming panel
After removing in 40, the bulge-structure 12 of spiricle shape opens up that leave spiricle shape recessed on the penetration type joint face surface of concrete component
Hole forms the concrete component with special-shaped penetration type joint face.Shaped face can significantly increase rear pouring concrete and concrete
The contact area of native component improves the cohesive force of the two, enhances the mechanical property of the area Hou Jiao concrete.
In addition, in step s 6, can not also deflate to membrane body 10, directly be rotating membrane body 10 from forming panel 40
Extraction.Specific practice are as follows: keep the connected state of valve 33 to be in off state, by air inlet pipe 32 and exhaust pipe 35 from valve 33
Upper dismounting rotates the fixed plate 20 that do not remove on membrane body 10, so that membrane body 10 is rotated pumping from membrane body 10 from forming panel 40
Out.At this point, the penetration type joint face of concrete component by there are 10 perficial helical line shape bulge-structure 12 of membrane body open up out it is a plurality of
The helically pit of line shape, and due to membrane body 10 during rotating extraction bulge-structure 12 and penetration type joint face it is mutual
Spin friction, the pit surface resulted in is rougher, so that penetration type joint face becomes the abnormity of rougher spiricle shape
Face.Both rougher shaped face can significantly increase the contact area of rear pouring concrete and precast concrete, greatly improve
Cohesive force, enhance the area Hou Jiao concrete mechanical property.
In addition, can also by change 10 surface bulge structure 12 of membrane body shape and arrangement mode, such as: bulge-structure 12
Shape be also possible to calabash shaped, droplet shape, twill-like etc., arrangement mode be also possible to it is arranged in parallel, be staggered；According to
Practice of construction needs to form the shaped face with the various constructions of different mechanical properties in the penetration type joint face of concrete component,
And then gas-filled formwork 100 is enable to make flexibly adjustment according to actual needs.
Alternatively, it is also possible to which membrane body 10 is fabricated to after gassy in the membrane body 10 after different shape, such as gassy
It is also possible to cuboid, frustum, terrace with edge etc..Form the penetration type joint face of concrete component with of different shapes various different
Shape face, and then gas-filled formwork 100 is enable to make flexibly adjustment according to actual needs.
The action and effect of embodiment
A kind of user of the gas-filled formwork applied to prefabricated assembled concrete component according to involved in the present embodiment
Method, because using a kind of inflatable gas-filled formwork for obtaining rigidity, and gas-filled formwork surface has bulge-structure, is pouring coagulation
Gas-filled formwork is put into the forming panel of casting concrete component before native component, after concrete component initial set, then will inflation
Template, which deflates to extract out or do not deflate, rotates the application method of extraction.So one kind of the invention is applied to prefabricated assembled coagulation
The application method of the gas-filled formwork of native component has the characteristics that make prefabricated assembled concrete component faying face to become shaped face, into
And the contact area of rear pouring concrete and precast concrete is significantly increased, the cohesive force of the two is improved, the enhancing area Hou Jiao is mixed
Coagulate the mechanical property of soil.And the gas-filled formwork of this method also has the characteristics that detachable, small in size and self weight is small, therefore pacifies
Dress, transport are all very convenient, and the gas-filled formwork of this method can be reused, and have stronger economic and practical, in addition our
Method reduces significantly compared with the difficulty of construction of traditional such as punching block, wooden model.
Above embodiment is the preferred case of the present embodiment, is not intended to limit the protection scope of the present embodiment.
