8 steel pins 6 of φ of 600mm are realized the splicing of template 1, are removed.
Template 1 of the present invention is spliced, in demolishing process, only needs directly install steel pin 6, remove, you can reach quick
Spell the purpose of form removal 1；The installation of stainless steel countersunk head screw component 5, using the inside of shear wall formwork 1 stay set horn mouth (or
The small structure of the outer imperial palace of person), countersunk head screw is installed by horn mouth side, passes through the side of installation nut after shear wall formwork 1 and angle steel 4
Formula had not only realized being fastenedly connected for angle steel 4 and template 1, but also can avoid after shear wall concrete formation that there are installation stainless steel spiral shells
The trace of bolt assembly influences shear wall concrete impression quality.
The present invention at least has the advantage that：
1, angle steel 4 of the present invention reinforces external member and small, high recycling rate is lost, and consolidation effect is apparent, can guarantee shear wall
Concrete formation quality.The angle steel 4 that a set of higher suitable splicing of shear wall different parts template 1 of reuse rate is reinforced fills
It sets, reaches and 1 stitching portion of shear wall formwork is reinforced, and the spelling of template 1 is torn open conveniently, not because splicing, removing the purpose being damaged.
2, angle steel 4 of the present invention reinforces the use of external member and can effectively accelerate the spelling of template 1 and tear speed open, accelerates construction progress, reduces
Construction cost.
3, the use of 4 rigidized cover of angle steel of the present invention can reduce the damage of template 1, improve shear wall concrete formation quality,
Template 1 is set to install more standardized, it is more beautiful.
The spelling of shear wall formwork 1 that the avoidable traditional reinforcing mode of the present invention is brought is torn time-consuming and laborious and template 1 open and is being spelled
It connects, be damaged in demolishing process, influence shear wall concrete formation quality.Reach and improve 1 recycling rate of waterused of template, raising is cut
Power wall concrete formation quality, while accelerating the spelling of template 1 and tearing construction speed open, reduce the effect of construction cost.It can generate larger
Social benefit has higher application value.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, it is noted that all
All any modification, equivalent and improvement made by within the spirit and principles in the present invention etc. should be included in the guarantor of the present invention
Within the scope of shield.
