How is the arrangement of the slab type balcony slab and the wall beam cast in situ, since there are

The structural arrangement of the balcony includes wall-mounting, beam-lifting and slab-lifting.

1. The wall-bearing type is to put the balcony slab directly on the wall, and its plate shape and span are consistent with the room floor, which is mostly used for concave balconies. Beams are raised from the inside and outside of the transverse wall, on which prefabricated floor slabs are placed, this structure is simple to arrange, the force transmission is direct and clear, and the length of the balcony is consistent with the room bay. The cross-sectional height H of the root of the pick beam is (1 5-1 6)L, L is the net length of the cantilever and the cross-sectional width is (1 2--1 3)h.

For the sake of aesthetics, a face beam can be set at the end of the pick beam, which can not only cover the head of the pick beam, but also bear the weight of the balcony railing, and can also strengthen the integrity of the balcony.

2. The beam type is to extend the beam at both ends of the balcony, and the balcony board is rested on the beam. When the floor slab is a cast-in-place floor slab, you can choose the pick plate type, and the cantilevered length is generally 1About 2m.

That is, the slab is picked out from the extension of the floor slab, the bottom of the slab is flat and beautiful, and the balcony plane form can be made into various shapes such as semicircular, arc, trapezoidal, oblique triangle and so on. The thickness of the pick plate is not less than 1 12 of the length of the pick.

3. The cross-section of the wall beam should be larger than that of the ring beam to ensure the stability of the balcony, and the balcony cantilever should not be too long, generally 1About 2m, and set drag beams at both ends of the wall beam to press into the wall.

Is this beam at the root of the balcony?
