Description
Technical Field
The invention belongs to the technical field of buildings, and particularly relates to an energy consumption connection node of a prefabricated sandwich concrete wallboard and a steel frame and an installation method.
Background
The national energy-saving technology and the building industrialization are greatly promoted, and compared with the common external wall, the sandwich heat-insulating external wall panel with the double functions of building energy saving and assembly modularization is more in line with the national policy and the adjustment of the industrial structure. At present, the sandwich heat-insulating external wall panel is mainly structurally characterized in that the inner side and the outer side are both inner and outer leaf plates of reinforced concrete sheets, the middle is a sandwich heat-insulating layer, and in order to strengthen the integrity of the combined action, independent connecting pieces or long steel bar trusses are also arranged in the structure to strengthen the effect of the combined action; however, in practical applications, this form of construction and structural connection has the following problems:
1) The independent connecting piece or the through long steel bar truss is adopted to strengthen the connection and the integrity between the inner leaf plate and the outer leaf plate, so that the connection and the integrity are fixed in the heat insulation layer material in a penetrating way, the tightness of the heat insulation layer is damaged, and the heat insulation performance is affected;
2) Because the inner leaf plate and the outer leaf plate are thinner, the hoisting and temporary supporting points of the two leaf plates are required to be embedded with hoisting supporting connecting pieces, and the connecting pieces and the concrete have the requirement of being sufficiently bonded and fixed, but in the thickness direction of the thin plate, the concrete cannot meet the requirement, the concrete entity range is increased in the hoisting point or supporting point area, and the inner leaf plate and the outer leaf plate are generally connected into a local integral structure, but the cold and hot bridge channels of the concrete are communicated, so that the heat preservation performance is influenced.
3) The installation of the connecting piece or the steel bar truss and the installation of the insulating layer material are crossed, and only manual operation is needed, so that the labor efficiency is low, the construction is complex, and the quality is difficult to ensure.
The prefabricated concrete externally-hung wallboard is used as a non-structural member, and only the dead weight of the prefabricated concrete externally-hung wallboard and the wind load and the earthquake outside a plane are required to be considered in design; the external wall board and the main body structure are often connected in a four-point flexible connection mode, and in the anti-seismic design, the external wall board can swing and deform or slide and deform in earthquake to adapt to the deformation of the main body structure, so that the external wall board is an important measure for reducing the interaction between the external wall board and the main body structure.
The application time of the precast concrete external wall panel in China is short, and the conventional connection mode between the single-layer whole precast concrete external wall panel and the main body structure in China is that the top is connected with an upper layer beam slab line through steel bars, and the bottom is connected with a lower layer beam slab by adopting lateral angle steel; in the rigid connection mode, two rows of steel bars reserved at the top of the externally hung wallboard extend into the floor cast-in-situ layer, solid end constraint is formed under the out-of-plane load action, and the construction quality and the safety under the earthquake action are easy to ensure; in order to reduce the influence on the damage mode of the main structure under the earthquake action, the connecting steel bars at the top should avoid the plastic hinge area at the beam end, and the horizontal sliding deformation is mainly used between the external wall panel and the main structure under the horizontal earthquake load action.
Research shows that no matter flexible point connection or rigid line connection is adopted, larger interaction exists between the externally hung wallboard and the main body structure; this interaction has a non-negligible effect on the stressing performance of the components directly connected to the wall panel, the dynamic characteristics and damage mechanism of the overall body structure, and the stressing performance of the external wall panel itself.
