Problems solved by technology

[0006] 4. Since the hole opening of the pin-key beam cannot be very standard, but the concrete of the pin-key beam must fill the hole without leaving any gaps, which also causes difficulties in concrete construction
[0007] 5. Due to the large number of pin-key beams, there are also many problems in the construction, which seriously affects the quality control difficulty of seismic isolation reinforcement and prolongs the construction period

Abstract

The invention relates to a brick and concrete reinforcement structure for a shock insulation support and a mounting and underpinning method thereof, mainly uses concrete-filled steel tube cylindrical precast pin key beams to perform shock insulation treatment on the foundation, and belongs to the aseismatic reinforcement field. The structure comprises a patand, a precast pin key beam, an upper shoulder beam, a lower shoulder beam, an upper seal plate and a shock insulation support. According to the brick and concrete reinforcement structure for the shock insulation support and the mounting and underpinning method thereof, concrete-filled steel tube cylindrical precast pin key beams are used to replace traditional reinforced concrete rectangular cast-in-place pin key beams to perform shock insulation treatment on the foundation. By means of the concrete-filled steel tube cylindrical precast pin key beams, the structural strength is high, the integrity is good, and the construction is fast. The foundation shock insulation method is economic and reasonable and safe and reliable, and has broad application prospects.

Description

technical field [0001] The invention relates to a brick-concrete reinforcement structure for an earthquake-isolating bearing and an installation underpinning method thereof, which mainly utilizes concrete-filled steel tubular cylindrical prefabricated pin key beams to perform seismic isolation treatment on the foundation, and belongs to the field of seismic reinforcement. Background technique [0002] The pin-key beam is equivalent to the pin-key inserted in the load-bearing wall, through which the vertical load of the structure is transmitted to the shoulder beam. The cross-sectional shape of the pin-key beam in the traditional method is a rectangle, and the cast-in-place concrete construction process is used. In order to ensure the connection between the pin key beam and the shoulder beam, steel bar joints should be left outside; in order to ensure construction and formwork installation, the size of the pin key beam opening should be larger. It has the following disadvant...
