Outboard template 23.
The present embodiment provides a kind of cornice form removable methods under racing track, since formwork erection injection is sprayed with no formwork erection
It penetrates, can have some faulting of slab ends in joint face causes layering situation obvious, therefore it is required that template is removed before initial set, and
Shi Jinhang seam surface treatment, reaches overall effect, specifically, in the levelling completion of the inner surface of concrete ejection, lower cornice 20
Afterwards, before concrete initial set, first the support bar 24 and the inner side template 22 are removed simultaneously, to be conducive to avoid to mixed
Coagulate the influence of soil；It is further continued for removing the levelling pipe 21, is not only advantageous to be influenced minimum, Er Qiebao by external force to cornice concrete
Card cornice concrete integral structure is not destroyed, and after the completion of the levelling pipe 21 is removed, is reached usually to racing track gunite concrete
It is further continued for removing the outboard template 23 after collapsible die intensity, to advantageously ensure that the stabilization of the concrete in demolishing process.
When in addition removing, third self-tapping screw and the second self-tapping screw are first exited, finally exits first self-tapping screw,
It thereby may be ensured that and remove the inner side template 22 and the support bar 24 simultaneously, guarantee is influenced cornice concrete by external force
It is minimum.Furthermore the levelling pipe 21 will carry out feed supplement to the position where it after removing, to advantageously ensure that whole device
Globality, it is specifically, smooth closely knit to being clogged at the levelling pipe 21 using the jetting material of same material, reach normal wait conserve
The outboard template 23 is removed after intensity again.
Obviously, the above embodiments are merely examples for clarifying the description, does not limit the embodiments.For
For those of ordinary skill in the art, other different form variations can also be made on the basis of the above description or are become
It is dynamic.There is no necessity and possibility to exhaust all the enbodiments.And obvious variation extended from this or change
It moves still within the protection scope of the invention.
