Embodiment 1

[0032] A kind of prefabricated assembled concrete stairwell outer wall assembly structure designed by the present invention, its schematic diagram is as follows figure 1 , image 3 , Figure 4 and Figure 5 shown. Including prefabricated load-bearing longitudinal shear wall panels 1.1, prefabricated load-bearing transverse shear wall panels 1.2, prefabricated beams 2, non-load-bearing external wall panels 3 and hanging panel connectors 4, the prefabricated load-bearing longitudinal shear force Wall panels 1.1 and prefabricated load-bearing transverse shear wall panels 1.2, the prefabricated beam 2 and non-load-bearing external wall panels 3 are used on the outer part of the tread plate 8 (the horizontal joints of the upper and lower non-load-bearing external wall panels 3 are located at the prefabricated beam 2 The upper edge of the upper edge of the left and right non-load-bearing external wall panels is located in the middle of the prefabricated beam 2); the prefabricated...

Embodiment 2

[0038] like figure 2 , Image 6 As shown, the structure and construction method of the prefabricated concrete stairwell exterior wall assembly structure are similar to those of Embodiment 1, the main difference is that: the prefabricated beam 2 and the non-load-bearing external wall panel 3 on the outer part of the tread plate 8, the upper and lower two non- The horizontal joint of the load-bearing external wall panel 3 is located in the middle of the beam body of the prefabricated beam 2 . So no more details.

Abstract

The invention relates to an assembly type concrete stairwell external wall structure and a construction method thereof. The structure comprises prefabricated bearing longitudinal shear wallboards, prefabricated bearing transverse shear wallboards, a prefabricated beam, a non-bearing out-hung wallboard and hanging board connection pieces. The prefabricated bearing longitudinal shear wallboards and the prefabricated bearing transverse shear wallboards are adopted for the outer side part of a rest platform, and the prefabricated beam and the non-bearing out-hung wallboard are adopted for the outer side portion of a step plate. One side of each prefabricated bearing longitudinal shear wallboard is connected with a stairwell cast-in-situ edge component through a lateral connection rebar, and the other side of each prefabricated bearing longitudinal shear wallboard is connected with the prefabricated beam through a reserved rebar overlapping region, and the prefabricated bearing longitudinal shear wallboards are connected with stair beams and rest platform floors in the vertical direction of the prefabricated bearing longitudinal shear wallboards. The left sides and the right sides of the prefabricated bearing transverse shear wallboards are connected with the stairwell cast-in-situ edge components through lateral connection rebars. The assembly type concrete stairwell external wall structure is light in weight, good in wall limb stability, good in structural antitorque effect, easy and convenient to construct and low in cost.

Description

technical field [0001] The invention relates to an exterior wall structure of an assembled concrete stairwell and a construction method thereof, belonging to the technical field of reinforced concrete structure engineering. Background technique [0002] At present, the assembly structure of the external wall of the prefabricated concrete stairwell either uses prefabricated load-bearing shear wall panels or all uses external non-load-bearing external wall panels. These two structures have the following problems: [0003] 1. The construction of all prefabricated load-bearing shear wall panels has the following problems: a. The outer wall is long and rigid, but the connection between the large hole at the step position and the main structure is weak; the unsupported length is long, and the wall is stable and has hidden dangers; it only bears its own weight , the material does not fully exert its strength. b. Scissor ladders commonly used in high-rise residential buildings gene...
