Embodiment 1

[0030] like figure 1 and figure 2 As shown in the figure, the splitting and installation method of the high connecting beam type precast concrete wall includes the following steps:

[0031] Splitting the high connecting beam into independent upper connecting beam 2 and lower connecting beam 1 along the floor elevation 101;

[0032] Splitting the prefabricated concrete wall into one-piece concrete wall bodies 5 along each of the floor elevations 101 in the height direction;

[0033] Lay the seat slurry layer 4 below the upper connecting beam 2 above the floor elevation 101;

[0034] A filling layer 6 is arranged at the inner bottom of the concrete wall 5 along the length direction of the precast concrete wall, so that the filling layer 6 is located above the slurry layer 4;

[0035] Make supports 3 on both sides of the filling layer 6;

[0036] The concrete wall 5 is hoisted and fixed to the floor slab 100, and is poured integrally with the floor slab 100 on the same floor...

Embodiment 2

[0038] like figure 1 and figure 2 As shown, in the method for disassembling and installing a high-coupling beam-type precast concrete wall described in Embodiment 1, it is also possible to specifically split the high-coupling beams into independent upper coupling beams 2 and lower coupling beams 1 along the floor elevation 101. , first measure the height h1 of the high connecting beam below the floor elevation 101; set the height of the lower connecting beam 1 as h1.

[0039] It is also possible to specifically measure the height h2 of the high connecting beam beyond the floor elevation 101 before splitting the high connecting beam into the independent upper connecting beam 2 and the lower connecting beam 1 along the floor elevation 101; The height of 2 is set to h2.

[0040] Specifically, before splitting the high coupling beam into independent upper coupling beam 2 and lower coupling beam 1 along the floor elevation 101 , first measure the total height h of the high coupl...

Embodiment 3

[0043] like figure 1 and figure 2 As shown, the high coupling beam split node is used to realize the split installation method of the high coupling beam type precast concrete wall described in any one of Embodiment 1 or Embodiment 2, and the high coupling beam split node includes a slurry layer 4 and a filling layer 6, the seat The slurry layer 4 is laid above the floor elevation 101 and below the upper connecting beam 2; the filling layer 6 is arranged in the concrete wall 5 along the length direction of the precast concrete wall, and the filling layer 6 is located above the seat slurry layer 4; Supports 3 are provided on both sides of the filling layer 6 .

Abstract

The invention discloses a method for splitting and installing a high connecting beam type prefabricated concrete wall, a split node of a high connecting beam, and a high connecting beam and a high connecting beam type precast concrete wall. The lower connecting beam; the prefabricated concrete wall is split into a whole piece of concrete wall along the elevation of each floor in the height direction; the seat slurry layer under the upper connecting beam is laid above the elevation of the floor; The filling layer is arranged in the length direction of the precast concrete wall, so that the filling layer is located above the seat slurry layer; supports are made on both sides of the filling layer; the concrete wall is hoisted and fixed to the floor, and the concrete is poured with the same floor to form a whole; It avoids the disconnection of the shear reinforcement in the high coupling beam due to splitting, thereby ensuring the stability of the shear bearing capacity of the high coupling beam, solving the structural safety problems caused by the splitting problem, and improving structural safety.

Description

technical field [0001] The invention belongs to the technical field of disassembly and installation of prefabricated concrete buildings, and in particular relates to a disassembly and installation method of a high-coupling beam type precast concrete wall, a high-coupling beam split node, and a high-coupling beam and a high-coupling beam type prefabricated concrete wall. Background technique [0002] Prefabricated buildings have developed rapidly in recent years, and the construction industry everywhere is undergoing transformation and upgrading. Two-fabricated buildings are the main development direction. At present, prefabricated concrete structures are mainly used in prefabricated concrete shear wall structures, while prefabricated concrete shear wall structures are mainly used in high-rise residential buildings with shear walls. In the 30-story shear wall structure, most of the coupling beams are high in height, and even due to the limitation of windows, the coupling beam...
