Problems solved by technology

[0003] In the prior art, Indirli used a prestressed steel rod device to prevent earthquakes from a masonry bell tower in Italy. However, on the one hand, the device still needs to be directly anchored to the top of the bell tower, affecting the cultural relic itself; The prestressed cable system cannot limit the failure modes such as local out-of-plane instability of the structure and tension cracking of the opening
China has carried out research and practical work on the protection of the main body of ancient masonry pagodas, but the existing reinforcement methods "Integral Seismic Reinforcement Method of Masonry Ancient Pagodas (Publication Number: 104153596B)" and "Reinforcement of Ancient Brick Pagodas with Prestressed Carbon Fiber Board Hoops" The method and device (publication number: 103541558B)" require large-scale slotting for the overall height of the tower body and / or prestressed hoops and other parts, which will cause irreversible impact on the cultural relics

specific Embodiment 1

[0032] Such as figure 1 As described above, an anti-seismic prestressed cable system for masonry ancient pagoda cultural relics includes a top fixing component 2, a vertical prestressing component 3, a circumferential prestressing component 4, and an anchoring end component 5, and is characterized in that: the top fixing component 2 The bottom is a card-groove structure, and it is connected with the top of the main body of the masonry ancient pagoda cultural relics by a card. The upper end of the vertical prestressing component 3 is hinged to the top fixing component 2 in a plane, and after the vertical prestressing is applied, the lower end of the vertical prestressing component 3 is hinged to the anchoring end component 5 in a plane. The hoop prestressed component 4 is located at the elevation of each floor of the main body of the masonry ancient pagoda cultural relics, and is connected with the vertical prestressed component 3 by bolts. . The anchoring end assembly 5 is l...

specific Embodiment 2

[0039] Such as figure 1 As mentioned above, the anti-seismic performance improvement device for the ancient masonry pagoda cultural relic body 1 in this embodiment includes a top fixing assembly 2 , a vertical prestressing assembly 3 , a circumferential prestressing assembly 4 and an anchoring end assembly 5 . The main body of the masonry pagoda cultural relics 1 is a three-story hollow ancient pagoda with a regular hexagonal cross-section and a top wall thickness of 400mm. The bottom of the top fixing component 2 is a card groove structure, and is connected with the top of the main body of the masonry ancient pagoda cultural relic 1 by a card. There are 6 sets of vertical prestressing components 3, the upper end of each set of vertical prestressing components is hinged with the top fixing component 2, and after the vertical prestressing is applied, the lower end of each set of vertical prestressing components is hinged with the anchoring end component 5. The hoop prestressed...

Abstract

An anti-seismic prestressed cable system for masonry ancient pagoda cultural relics and a prestressed determination method, the cable system includes a top fixing component, a vertical prestressed component, a circumferential prestressed component and an anchoring end component; the vertical prestressed component is located at Between the top fixing component and the anchoring end component, the hoop prestressed component is installed horizontally at the level of each floor of the masonry ancient pagoda cultural relics, and two-way cable clamps are set at the intersection of the double cables for connection; the two-way cable clamps include The inner backing plate, the middle cover and the outer cover are arranged vertically in sequence; the vertical cable is clamped in the channel formed by the fastening of the inner backing plate and the middle cover, and the hoop is sandwiched between the middle cover and the outer cover In the formed channel, prestress is applied to the double cables respectively. The prestress is determined on the premise of the principle of minimum intervention in the protection of cultural relics, and based on the pushover analysis of the discrete body model, the aseismic performance of the masonry ancient pagoda cultural relics is evaluated. The invention does not need to slot or break holes in the cultural relic body, has strong reversibility, and completely preserves the historical information of the masonry ancient pagoda cultural relics.

Description

technical field [0001] The invention belongs to the field of anti-earthquake protection of cultural relics, and in particular relates to an anti-earthquake prestressed cable system for ancient masonry pagoda cultural relics, which is suitable for anti-seismic protection of the main body of ancient masonry pagoda cultural relics that are becoming increasingly loose. Background technique [0002] The main body of ancient masonry pagodas is very fragile in the face of earthquake disasters. Earthquake action is likely to cause the overall structural collapse of the main body of the masonry ancient pagoda cultural relics, partial collapse, or cracks in the vertical weak zone between the holes in each layer. Once the ancient tower is damaged, the cultural relics collected in the tower will also suffer huge losses. Therefore, it is an urgent task to develop an effective anti-seismic performance improvement device for the main body of the masonry ancient pagoda cultural relics. ...
