Assembled external wall structure and construction method

Abstract

The invention relates to an assembled external wall structure and construction method. The external wall structure comprises a vertical keel, a transverse keel, a holding-plate element, a supporting plate, an external wall plate unit, a water-conducting strip and a sealing joint strip. The vertical keel is arranged on the building main body and the transverse keel is connected with the vertical keel. The holding-plate element is adjustably arranged at the transverse keel and the transverse supporting plate is arranged at the holding-plate element. The external wall plate unit is sandwiched between the supporting plates. The vertical joint between the external wall plate units corresponds to the vertical keel. The water-conducting strip is arranged at the vertical joint and the water-conducting strip is sleeved on the vertical keel. The sealing joint strip is blocked at the outer end of the water-conducting strip. The assembled external wall structure sets up two waterproof devices which prevents outdoor rainwater leakage by utilizing the blocking and discharging method in the slab joint, namely the water-conducting strip and the sealing joint strip. When the aging of the sealing joint strip happens because of the longstanding utilization of the sealing joint strip, the rainwater can be derived by the water-conducting strip arranged in the slab joint and not be let in the room, which has a good waterproof effect.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to an assembled exterior wall structure and a construction method thereof. Background technique [0002] The prefabricated assembly process is more and more widely used in construction engineering. In the prefabricated assembly process, connectors are used to assemble various prefabricated components to form the required structure. In the prefabricated building, the exterior wall panels are produced in a prefabricated manner, and then assembled on site, so that standardization can be achieved, and the quality is controllable, efficient and fast. [0003] At present, prefabricated exterior wall panels are installed by integral hoisting. Due to the overall weight of prefabricated exterior wall panels, they need to be embedded between steel beams and steel columns during assembly, which has the problems of difficult hoisting and low efficiency. In addition, in the assem...
