Anonymous users2024-01-24The concrete strength of the cantilevered structure must reach 100% of the design strength before the formwork can be removed.
upper part 3 - diameter 25 steel bars, protruding into the side wall beam or frame beam 2 meters; >>>More
It has nothing to do with the length, it is the tendon in the width direction! One end extends into the inner floor slab of the beam 500 anchorage, the anchor end is 90 degrees hooked, the balcony outside 180 degrees hook, 16 threaded steel bars 150 are evenly distributed at intervals, the distribution of steel bars in the length direction is not subject to any force, 12 reinforcing bars are evenly distributed at intervals, and the reinforcing bars are arranged near the upper surface of the balcony slab, the thickness of the protective layer is 25, and the rebar grade is HRB335.
To carry out the overturning calculation, there is no ring beam addition, generally extend into the wall 2-3 times the length of the pick-out.
The beam size is unknown, the load is unknown. In general, if the beam of the residential building is 400 high, the gluten of the beam is matched with 2 16, the gluten of the balcony slab extends from the floor surface, and the rest of the steel bars are matched according to the structure.
The cantilever 2 meters mentioned by the subject, the balcony with a span of 4 meters, the cantilever beam with a cross-section of 250x500, the upper reinforcement adopts 5C20 3 2, the bottom reinforcement is 3C16, the stirrup is C8@100, and the waist reinforcement is 2C12, so the configuration is sufficient. Here's a simple calculation for you through the model, as shown in the figure below: >>>More
