This stair spare unit creativity all is connected with the bracket on outer wall and inside support piece, stair and half space formula structure as an organic whole in the stair prefab, and the back is connected with the bracket to the half space of tip department, enables the stable connection in outer wall and inside support piece department in both ends of whole stair prefab.
The bracket is a metal piece fixedly connected to the side part of the outer wall. Of course, it is also possible that the bracket is a block of concrete material, in which case the bracket is connected to the outer wall by means of fasteners.
In the above staircase unit, the interior support is an interior wall.
In the above staircase unit, the inner support is a ladder beam.
In the above staircase unit, the bracket is fixedly connected with the staircase prefabricated member through the dowel bars.
In the above staircase unit, the joint bars are provided with concrete grout.
The dowel bars play the pre-positioning role, and the connection part of the stair prefabricated member and the outer wall or the internal supporting piece is compact in structure after grouting.
In the above staircase unit, the outer wall is a prefabricated member.
In the above staircase unit, the staircase preform has a chamfer at the end.
Such a structure enables smooth and stable connection of the stair preform at the corbel.
The second object of the present invention can be achieved by the following technical solutions:
a method of constructing a staircase unit, the method comprising the steps of:
A. preparing: the bracket and the stair prefabricated member are reserved;
B. the bracket is connected: a plurality of evenly distributed brackets are connected to the outer wall along the up-down direction, and a plurality of evenly distributed brackets are connected to the inner supporting piece along the up-down direction;
C. pre-connection: connecting one end of the stair prefabricated member to a bracket of the outer wall, and connecting the other end of the stair prefabricated member to a bracket of the internal support member;
D. positioning and connecting: the end part of the stair prefabricated member is connected with the bracket through the dowel bars, concrete grouting is adopted at the joint, and the concrete is solidified and formed to form the integral stair member unit.
It can be seen that, because the bracket is connected to the outer wall or the inner support member in advance, the end of the stair prefabricated member can be stably connected to the outer wall or the inner support member after being connected with the bracket.
After the positioning connection, because the concrete grouting is arranged at the joint, the connection stability can be further improved, and the structure is compact.
In the above construction method of the staircase unit, the inner supporting member in the step B is an inner wall.
In the above construction method of the staircase unit, the inner support in step B is a ladder beam.
In the construction method of the staircase units, gaps are formed at the joints of the staircase prefabricated members and the brackets in the step D, steel bar meshes are laid at the gaps, then glue sealing slurry is applied, and finally the gaps are filled with the mortar.
Therefore, the structure of the joint is more compact, and the joint has proper strength.
Compared with the prior art, this staircase unit just can make the stable connection of stair prefab between outer wall and inside support piece behind the stair prefab end connection on the bracket, consequently, the construction is quick simple and convenient, and efficiency is higher.
Meanwhile, the construction method can also ensure that the joint of the stair prefabricated member has enough strength and compact structure, and has very high practical value.
