In the case of no column, how to deal with the beam frame on the slab wall?

Model the cast beam directly on the slab wall.

Summary. Hello, the beam plate can be reinforced with independent columns. Column, beam plate concrete strength is not the same then can only be poured separately, if the wall column, beam plate at the same time formwork, then do not have to wait for the day after pouring the beam plate, special frame structure after pouring a part of the column can be poured beam plate, just pay attention to distinguish the concrete mark.

As for the production of cold joints, the top of the column at the bottom of the beam itself is allowed to set up the construction joints, which is completely possible. From the consideration of the construction period, it is most economical and feasible to support the formwork at one time, and pour a part of the column and then pour the beam plate.

Can it be used independently?

Columns, beams and slabs concrete strength is not the same, then can only be poured separately, if the wall columns, beams and slabs at the same time formwork, then do not have to wait for the day after the line of silver fingers pouring beams and plates, special gear with different frame structure after pouring a part of the column can be poured beams and plates, just pay attention to distinguish the concrete number.

Can I add it after it has been poured?

OK. How to construct it.

It is definitely not possible to directly pour the wide annihilation, you can punch holes on the sides of the walls and floor slabs, and install a tripod made of angle iron. The steel bar is drilled on the side of the floor slab, and the steel bar is best to hook the steel bar inside the hole. Then rely on these steel bars to tie the net, and then pour cement.

The tripod is poured there into a triangular solid structure.

Theoretically, the problem is not big, because both the stability and strength of the steel column are caused by load. If the steel beam is not erected and the roof is not installed, then basically the steel column is not loaded, so there should be no problem.

However, it should be ensured that the steel structure is static if the steel beams are not installed, that is, the steel columns themselves can stand (just connected to the column foot, or supported by other floor beams).

The steel structure beam does have the effect of lateral support on the steel column, so as to improve the lateral stability of the steel column and reduce the displacement of the column top. But it's not that all steel columns need to have beams. In China's steel gauge (GB50017-2003) and anti-gauge (GB50011-2010), the allowable slenderness ratio of each member is given.

As long as the requirements are met, the steel beam can be omitted.
