Parapet wall anti-seismic integral reinforcing method and structure

Abstract

The invention discloses a parapet wall anti-seismic integral reinforcing method and a structure. The parapet wall anti-seismic integral reinforcing method is characterized in that a reinforced concrete reinforcing depression bar is additionally arranged at the top of a parapet wall body, and fixing anchor bolts are pre-embedded in the inner side and the outer side of the reinforced concrete reinforcing depression bar; flat steel bars arranged on the outer side of the parapet wall body and the vertical angle steel and the horizontal angle steel which are arranged on the inner side of the parapet wall body are connected into an integral steel structure frame through the fixing anchor bolts and through bolts penetrating through the parapet wall body to hoop the parapet wall body; and meanwhile, the overall steel structure frame and an embedded steel plate of a building roof are welded into a whole, so that the anti-seismic property of the parapet wall is improved. According to the parapet wall anti-seismic integral reinforcing method, the anti-seismic performance of the parapet wall is effectively improved, and the original brick-concrete structure parapet wall can meet the standard anti-seismic requirement; and according to the method, construction is convenient, too many construction facilities do not need to be prepared on site during construction, the safety of the parapet wall is improved, and the method is particularly suitable for conducting anti-seismic reinforcement on existing buildings with parapet walls which do not meet the anti-seismic standard design and has very high social benefits.

Description

technical field [0001] The invention relates to an anti-seismic integral reinforcement method and structure of a parapet wall, belonging to the technical field of assembled building molds. Background technique [0002] The parapet is the low wall around the roof of the residential buildings in our country. In addition to the roof maintenance and safety, the parapet also has the function of waterproofing the bricks to prevent the waterproof layer from seeping or the roof rainwater from overflowing; the parapet also has a role in building facades Decorative effect. The height of the parapet wall is generally between 1.2m and 1.5m, and the parapet wall is basically made of brick-concrete structure. Especially for the buildings built before the 1990s, no relevant seismic structural measures were taken for the parapet wall, resulting in the damage of the parapet wall. The anti-seismic performance is poor, and incidents of parapet falling off and collapsing during earthquakes fre...

AI Technical Summary

Problems solved by technology

The height of the parapet wall is generally between 1.2 meters and 1.5 meters. The parapet wall is basically made of brick-concrete structure. Especially for the buildings built before the 1990s, no relevant earthquake-resistant structural measures have been taken for the parapet wall, which leads to the damage of the parapet wall. The anti-seismic performance is poor, and incidents of parapet falling off and collapsing during earthquakes frequently occur
