The wall vertical reinforcement U-shape structure at top builds the second support system in being staggered in bonding pad, while for horizontal member;
4) rib mould is installed on the outside of the plate in-situ layer of horizontal member;
8) the wall in-situ layer of wall, the plate in-situ layer of horizontal member and bonding pad are overlapped with concreting second;
9) rib mould on the outside of the plate in-situ layer of horizontal member is removed;
10) overlapping of lifting first wall, and being placed into installation site vertically makes the other end of vertical connection reinforcing bar stretch into first
Overlap in the stiffener hoop in the wall in-situ layer of wall, while the 3rd support system is built for the first overlapping wall;
11) the wall in-situ layer of wall is overlapped with concreting first, makes to overlap wall positioned at the first and second of bonding pad periphery
The plate in-situ layer of wall in-situ layer and horizontal member forms integrative-structure, you can.
Feature and effect:
The both walls preformed layer and its pre-buried various reinforcing bars of the overlapping wall of the present invention first and second are all prefabricated by plant produced,
Standardized work, high-efficiency high-quality is made, avoiding site operation needs a large amount of templates, scaffold, fastener, cement, sandstone, building materials
And environmental pollution, the processing that construction is brought waste problem low with long in time limit, efficiency.Again due to the wall of first and second overlapping wall
For laminar product, its internal links structural strength and overall performance all need further to be strengthened, and for building element, its
Structural strength and overall performance are vital, and therefore, the present invention not only pre-buried is within the walls disposed with wall water in first and second overlapping
Flat reinforcing bar, wall vertical reinforcement, also especially set up in both walls preformed layer and wall in-situ layer bridge the three square stirrup and
Truss bars, and square stirrup and truss bars are multiple, and parallel spaced-apart arranged is folded whole first and second from top to bottom
Close within the walls, so as to greatly improve first and second overlapping portion connects within the walls structural strength, overall performance and reliability.In addition, this
Elongated vertical connection reinforcing bar is had additional in the wall in-situ layer of first and second overlapping wall of invention, it is cast-in-place also further to strengthen wall
Structural strength, stress performance and the overall structural behaviour for overlapping wall of layer.The present invention is also prefabricated in the both walls of the second overlapping wall
Layer end is reserved with the wall vertical reinforcement of U-shape structure, when the wall vertical reinforcement of the U-shape structure and the first overlapping wall are connected,
Significantly enhance the structural strength and reliability of connecting node.
