Technical Field

The invention relates to the technical field of building structure engineering, in particular to a reinforced wall frame structure and a construction method thereof.

Background

At present, in the building structure of China, a masonry wall frame structure is still one of the widely applied forms, and a wall body is mainly used as a non-structural member with the functions of separation and enclosure and is generally built by concrete blocks, hollow brick masonry and light environment-friendly material blocks. Earthquake damage shows that the wall body and the frame are complex in interaction, the wall body is restrained by the frame, and meanwhile the frame is also restrained. In the early stage of earthquake, the wall body has large section, so that the rigidity is also large, but the strength is lower, so that the damage is more serious than that of the frame. In Wenchuan earth earthquake, the frame wall body is damaged and collapsed outside the plane. Because the wall body is not reliably connected with the frame beam and the frame column, the wall body is damaged and collapsed outside the whole plane under the action of an earthquake. Although the wall is susceptible to earthquake damage, domestic and foreign researches show that the masonry wall adopting certain earthquake-resistant construction measures can meet the earthquake-resistant requirements of the current specifications on building structures. The wall structure house has good anti-seismic performance after being provided with the constructional columns and the transverse tie beams, and can realize the goal of fortification without toppling over in large earthquakes. However, in the existing constructional column and transverse tie beam construction method, enough time needs to be reserved to wait for the concrete strength of the constructional column and the transverse tie beam to reach the expectation, and the problems of long construction period and complicated construction exist.
