2. the prefabricated column of stairwell is prefabricated as a whole, but the reinforced bar at the half-layer high stair platform is full length and concrete is poured later, the reinforced bar of the ladder beam is inserted into the post-pouring section of the prefabricated column to be anchored during site construction, the construction is difficult, meanwhile, the post-pouring concrete between the upper section and the lower section of the prefabricated column is added with a column template, and the pouring quality is difficult to guarantee.
Disclosure of Invention
The utility model aims to provide a node structure for connecting a prefabricated column and a cast-in-situ ladder beam in a stairwell, which ensures the integrity of the prefabricated column, reduces the number of prefabricated components and the number of column construction templates, and reduces the construction difficulty.
The purpose of the utility model is realized in the following way:
the utility model provides a node structure that prefabricated post of stair room and cast-in-place ladder beam are connected, includes the prefabricated post of stair room, prefabricated post of stair room has pre-buried ladder beam reinforcing bar, ladder beam reinforcing bar one end stretches out towards the ladder beam direction, and the prefabricated post of stair room still is provided with the keyway simultaneously, and the keyway embeds there is the connecting piece, the concrete has been pour in the ladder beam position, and ladder beam reinforcing bar and connecting piece insert in the concrete simultaneously, form cast-in-place ladder beam after the concrete air-dries.
The stairwell corner post leads to high whole prefabrication, and stairwell corner post pre-buried ladder beam reinforcing bar of half-layer high landing department stretches out certain length and carries out the reinforcing bar and connect, and stairwell corner post and ladder beam contact department increase the keyway moreover, have guaranteed the wholeness of frame post, satisfy the bearing capacity of cutting, have reduced prefabricated component quantity and post construction template, have reduced the construction degree of difficulty.
The aim of the utility model can be also solved by adopting the following technical measures:
further, the stair beam reinforcing steel bars are arranged at the positions of the stair well precast columns corresponding to the half-layer high stair platform.
Further, the ladder beam steel bars comprise ladder beam gluten and ladder beam bottom gluten.
Further, concrete is poured between the ladder beams, and a cast-in-place platform plate is formed after the concrete is air-dried.
Further, the cast-in-situ stair further comprises a prefabricated stair, the cast-in-situ stair beam is provided with steps, and one end of the prefabricated stair is fixed on the steps.
The beneficial effects of the utility model are as follows:
the stairwell corner post leads to high whole prefabrication, and stairwell corner post pre-buried ladder beam reinforcing bar of half-layer high landing department stretches out certain length and carries out the reinforcing bar and connect, and stairwell corner post and ladder beam contact department increase the keyway moreover, have guaranteed the wholeness of frame post, satisfy the bearing capacity of cutting, have reduced prefabricated component quantity and post construction template, have reduced the construction degree of difficulty.
