Embodiment Construction

[0035] The application will be described in detail below with reference to the drawings and embodiments.

[0036] In this embodiment, the relative rotation between the steel plates is used to realize the function of helping the frictional energy consumption of the tenon-and-mortise joint. Such as figure 1 As shown, the ancient-built wooden frame tenon-and-mortise joint friction damper includes a first steel plate part connected with a column 1, a second steel plate part connected with a beam 2, a friction plate between the plates 3, bolts and washers 4, used for the first steel plate The first hoop 5 for connecting the part 1 and the column, and the second hoop 6 for connecting the second steel plate part 2 and the beam. The first steel plate portion 1 includes a first substrate 8 and three perforated connecting pieces 9 fixedly connected to the plane of the substrate. The three perforated connecting pieces are spaced apart and parallel to each other; the second steel plate porti...

Abstract

The invention discloses a friction damper for ancient timber structure tenon-mortise joints, comprising a first steel plate portion (1) connected with a column, a second steel plate portion (2) connected with a beam, an inter-plate friction lining (3), a tightening bolt and washer (4), a first hoop (5) for connecting the first steel plate portion (1) with the column, a second hoop (6) for connecting the steel plate portion (2) and the beam, and a bolt hole (10). After assembly, the first steel plate portion (1) and second steel plate portion 92) connected with the beam and column can rotate relative to each other, coefficients of friction between all contact faces are equal, and a certain precompression is applied to a tightening bolt to control frictional amplitude. By making use the feature of a tenon-mortise joint dissipating energy by friction, the damper enables improved the ability of the tenon-mortise joint to dissipate energy and reduced secondary damage to an original structure and is small in size, easy to mount, maintain and replace and especially suitable for wide application in ancient timber structures.

Description

Technical field [0001] The invention belongs to a civil engineering component, and in particular relates to a friction damper device of an ancient wooden frame structure, which is mainly used for the reinforcement of the tenon-and-mortise joint of the wooden structure of the ancient building. Background technique [0002] The biggest feature of the wooden structure of ancient buildings is the tenon and tenon connection between beams and columns, which makes the structure very stable without one nail and one iron. Tenon-and-mortise joints have certain bending resistance and frictional energy dissipation capacity. However, due to their special connection methods, wooden frames are prone to joint pullouts and structural flashes in previous earthquakes. The reinforcement of tenon-and-mortise joints is imminent. . [0003] At present, the most common methods in the reinforcement of tenon-and-mortise joints are iron reinforcement, flat steel reinforcement, CFRP reinforcement and tinplat...
