Anti-seismic strengthening device of prefabricated hollow floorslab brick mixed structure building floor

Abstract

The invention relates to an anti-seismic strengthening device of a prefabricated hollow floorslab brick mixed structure building floor, comprising a bearing steel frame and an I-shaped steel band, wherein the bearing steel frame is a right-angle frame on which a catch spring plate and a catch spring shaft are arranged; the I-shaped steel band comprises a top flange plate, a web plate and a lower flange plate, wherein an installation slot is installed in the position in which an interval of 1200-1360 mm is formed between the lower flange plate and the web plate, and bolts, a catch spring sheetand a spring shaft sleeve are arranged in the installation slot. The invention has the following construction installation steps: installing the bearing steel frame on the side surface of a building ring beam in every 1.2 m by expansion bolts; splicing the top flange plate of the I-shaped steel band by engineering structural glue below the prefabricated hollow floorslab and above the bearing steel frame; putting the lower flange plate of the I-shaped steel band on the bearing plate of the bearing steel frame; and fixing the top flange plate between high-strength springs of the bearing steel frame by bolts. The hollow floorslab is elastically connected with the bearing steel frame by the I-shaped steel band and consumes seismic energy during the earthquake, preventing the hollow floorslab from falling off, preventing buildings from collapsing and ensuring safety of life and property of personnel.

Description

Prefabricated Hollow Slab Brick Concrete Structure Floor Seismic Strengthening Device technical field The invention relates to an anti-seismic reinforcement device for a prefabricated hollow floor brick-concrete structure building floor. Background technique Looking at the strong earthquakes in the world since the 20th century, the Alaska earthquake in the United States (March 28, 1964) was 8.8 on the Richter scale and 125 people died; on January 17, 1995 in Japan, a 7.3-magnitude earthquake occurred in the Hanshin area, killing 6434 people. ..... Among the previous earthquakes, my country suffered the most severe losses. More than 300,000 people were killed in the Tangshan earthquake and this Wenchuan earthquake. Beginning in 1996 after the Hanshin earthquake, Japan revised the "Building Standards Law" three times to raise the seismic standards of all types of buildings to the highest level, especially requiring the seismic capacity of commercial buildings to reach level ...
