Description

Assembled building shear wall assembly connection structure Technical Field The invention relates to an assembled building shear wall assembly connection structure, which is applied to the technical field of assembled shear wall assembly. Background As is known, prefabricated building is mainly referred to as a building formed by directly transporting prefabricated building elements to a construction site of a project and through a specific element connection mode, and compared with a traditional building, the connection mode of the building and the stability of the building have strict requirements. Compared with the cast-in-situ construction method, the assembly structure is beneficial to green construction, because the assembly construction can better meet the requirements of land saving, energy saving, material saving, water saving, environmental protection and the like of the green construction, reduces the negative influence on the environment, including noise reduction, dust emission prevention, environmental pollution reduction, clean transportation, site interference reduction, water saving, electricity, material and other resources and energy sources, and follows the principle of sustainable development. Because its bottom surface can not guarantee completely when prefabricated shear force wall is prefabricated to be leveled, the top surface of floor simultaneously probably has the burr pothole equally, need carry out vertical positioning and fixed connection through certain connection structure with the floor that has installed when prefabricated shear force wall is installed, and current operation mode is through the adjustment of wall position and straightness that hangs down is carried out to crane hoist and mount shear force wall and by means of instrument such as simple and easy crowbar of manual operation, and not only the operation degree of difficulty is big, and the efficiency of construction is low moreover. The application patent with the publication number of CN106760052A discloses a horizontal seam type steel welding connection device for an assembled prefabricated shear wall, and particularly discloses a horizontal seam type steel welding connection device which mainly comprises an upper connecting steel bar, a lower connecting steel bar, an upper steel bar, a lower steel bar, an upper connecting steel plate and a lower connecting steel plate, wherein the connection of the steel bars and the connecting steel bars and the manufacture of the prefabricated shear wall are all manufactured in factories in advance, and the assembly of the upper and lower prefabricated shear walls can be completed by only hoisting and splicing the upper and lower prefabricated shear walls on site and temporarily fixing the upper and lower steel bars.
