The utility model discloses the shear wall can reduce lateral stiffness, improve the thermal -insulating, sound insulation effect.

The invention relates to the technical field of constructional engineering, in particular to an ultrahigh light composite partition wall system with the fire endurance larger than or equal to 5 h and a construction method thereof.According to the system, a 200 mm composite wall core is formed by clamping calcium silicate fireproof plates between double-layer foamed ceramic battens, and the exterior of the composite wall core is coated with an expansion type fireproof coating; the steel structure joints are connected in a composite mode through U-shaped clamps and fireproof glue, and the steel beams and the steel columns wrap fireproof plates and are sprayed with fireproof coatings. Constructional columns are arranged on the wall body with the length larger than or equal to 6 m, and vertical connecting plates are arranged twice; the normal-temperature, soaking and compression-shear strength of the special fire-resistant rubber is greater than or equal to 1MPa. Standardized construction comprises the steps of paying off, steel structure installation, U-shaped clamp fixing, single-side batten installation, fireproof plate embedding, other-side batten installation, correction, steel structure fireproof coating, joint sealing and acceptance inspection. The ultrahigh light composite partition wall system and the construction method thereof have the characteristics that the fire-resistant integrity is larger than 300 min, the surface density is smaller than or equal to 600 kg / m < 2 >, and no crack exists when a single wall reaches the top by 9 m at a time, can be widely applied to first-level fire partitions of museums, data centers and the like, and are light, high in strength, fast to mount and low in comprehensive cost.

A connecting joint of a constructional column, a ring beam and a frame shear wall structure in a high earthquake area comprises a masonry structure part composed of masonry, a concrete ring beam and a concrete constructional column and a main body structure part composed of a frame beam and a frame column or a shear wall, and a transverse connecting structure is arranged between the concrete ring beam and the frame column or the shear wall. And a vertical connecting structure is arranged between the concrete constructional column and the frame beam. The transverse connecting structure comprises a transverse steel bar, one end of the transverse steel bar is embedded in the frame column or the shear wall, a transverse PVC sleeve is arranged in the concrete ring beam, and the other end of the transverse steel bar is inserted and embedded in the PVC sleeve. The vertical connecting structure comprises a vertical steel bar, one end of the vertical steel bar is embedded in the frame beam, a vertical PVC sleeve is arranged in the concrete constructional column, and the other end of the vertical steel bar is inserted into the vertical PVC sleeve embedded in the concrete constructional column.

The invention discloses a design method for controlling force flow of a building structure based on staged hinging. The design method comprises the steps that firstly, an overall simulation model of the building structure is constructed, the ends of all components are set to be in rigid connection, the self weight and additional dead load of the structure are input, and the stress conditions of all the components are analyzed; secondly, calculating the bending moment of each component under different influence factors, analyzing the big bending moment cause of the end part of each component, and determining the end part of the component needing to be adjusted and connected; after the initial simulation model is restored, the ends of the components needing to be adjusted and connected are arranged to be hinged, the self weight of the structure and the additional dead load are applied again, and the bending moment of each component is calculated; and finally, under the condition of keeping the internal force state of the component when the dead load is applied, defining the end part of the hinged component as rigid connection, applying different influence factors, calculating the internal force of the component, and checking the strength and the stability of the component. By means of the design method, the bending moment borne by the specific component is reduced, the structure redundancy is not reduced, and the anti-seismic performance of the structure is not changed.
