Abstract

The invention discloses a construction method for hanging and connecting prefabricated concrete external retaining sandwich type wall panels. The method includes the steps that the upper portions and the lower portions of the multiple prefabricated concrete sandwich type wall panels to be hung on floor slab edges of a concrete main body structure are connected with connecting parts in the transverse direction correspondingly; as for the two prefabricated concrete sandwich type wall panels adjacently arranged left and right, foamed rubber strips are fixed to two side surfaces of one wall panel correspondingly, and a foamed rubber strip is fixed to one side surface of the other prefabricated concrete sandwich type wall panel; A-level fireproof insulation materials are laid in a set position of a ground beam on the outer side of a main body outer edge beam cornice at the lowest layer in a through mode; and then the connecting parts are used for installing the prefabricated concrete sandwich type wall panels. By the adoption of the method, the installation speed is high, the adjustment precision is high, the appearance effect is good, and the connecting strength is high.

Description

technical field [0001] The invention relates to a construction method for connecting prefabricated concrete external protection sandwich wall panels, in particular to a construction method for hanging and connecting prefabricated concrete external protection sandwich wall panels. Background technique [0002] The prefabricated building is assembled on the construction site with prefabricated components. It has a high degree of factoryization and standardization, fast construction speed, energy saving and land saving, and good economy. It has become an important direction for my country to promote the development of construction industrialization. The current construction method of hanging and connecting precast concrete external protection sandwich wall panels generally adopts the method of direct hanging and welding, and manually adjusts. The position of the wall panels is difficult to control, and bumps are prone to occur during the installation and adjustment process, whic...
