More solid firm.
Embodiment of the present invention Main Basiss below equation adjusts cap（Without setting cap, then refer to cylinder）Size
And its periphery superstructure solid area（It is not embedded with the region of core 13）Scope, increase cap（Cylinder）The Punching Shear of periphery
Region, makes cap（Cylinder）The superstructure of periphery meets the requirement by punching bearing capacity：
Fl≤(0.7βhft+0.25σpc,m)ηumh0；
η=min (0.4+1.2/ βs,0.5+αsh0/4um)；
In above formula, FlFor concentrating counter-force design load；βhFor influential factor of sectional height；σpc,mFor calculating two on perimeter of section
Concrete effective compressive pre-stress in individual direction presses the weighted mean of length；umFor calculating the girth in section, take counter-force in distance set
Active area periphery h0The least favorable girth of plate vertical cross-section at/2；h0For effective depth of section；η1For concentrating counter-force active area
The impact coefficient of shape；η2For calculating the impact coefficient of perimeter of section and the ratio of plate effective depth of section；βsFor Local Loads or collection
Middle counter-force active area is the ratio on long side during rectangle and short side dimension；αsAffect coefficient for post position.
It is computed and finite element analyses, the cap width for having beam superstructure, in the embodiment of the present invention（Length）
Being generally this has beam superstructure B-C post width（Length）1.05～1.15 times.Under equal conditions, without beam hollow building cover with have
Beam hollow building cover is compared, and supports the solid area of pole unit 2 periphery in without beam hollow building cover（It is not embedded with the area of core 13
Domain）Width（Length）For there being 1.03～1.15 times of beam hollow building cover.
Following table is different spans, the different actual plate thickness using without beam hollow building cover under function, different load situation and post
Cap dimensional conditions：
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Any modification, equivalent or improvement made within god and principle etc., should be included within the scope of the present invention.
