Example Embodiment

[0016] The preferred embodiments of the present invention will be described in detail below with reference to the drawings.

[0017] Such as figure 1 As shown, the outer wall of the inner tube 1 is attached to the inner wall of the outer tube 2 and inserted into the outer tube to form an inner tube insertion section 3 and an inner tube exposed section 5. The cover plate 4 is located at the inner end of the inner tube insertion section and covers the inner tube The end of 1. figure 2 for figure 1 A-A section view, such as figure 2 As shown, the inner tube is formed by splicing two tube walls 9 with a semicircular cross section. At the same time, as image 3 As shown, the cover plate is formed by splicing two semicircular cover plate dividing blocks 10, and the arc edge of each cover plate dividing block 10 is connected to one of the two pipe walls. The diameter sides are spliced ​​with each other to form the whole cover plate. Such as figure 1 As shown, the expanded cement slur...

Abstract

The invention relates to an energy dissipating element of a grouting sleeve, which belongs to the field of structural engineering for fixing buildings and comprises an inner tube and an outer tube. A cover plate is arranged at one end of the inner tube, the inner tube together with the cover plate is divided into a plurality of independent single blocks along the axis direction of the inner tube, each single block consists of a tubular wall and a cover plate block, the outer wall of the inner tube which is divided into blocks is attached onto the inner wall of the outer tube and inserted into the outer tube so that an inner tube insertion section and an inner tube exposed section are formed, the cover plate which is divided into blocks is disposed in the end of the inner tube insertion section, and expanding cement grout is injected into the inner tube insertion section through the inner tube exposed section, so that an expanding cement grout body is formed. The energy dissipating element of the grouting sleeve is capable of guaranteeing construction quality and increasing friction among sleeves effectively, has the advantages of convenience in processing and mounting, economy and reliability, and can be used as a structural load-bearing component when in an earthquake non-resistant state.

Description

technical field [0001] The invention relates to the field of structural engineering of fixed buildings, in particular to an energy-dissipating support for reducing damage to buildings or structures caused by earthquake load effects. Background technique [0002] Structural control technology for earthquake resistance has become the main research object of building structure design. Structure control technology includes active structure control technology and passive structure control technology. Energy-dissipating bracing technology is one of the more common passive control technologies, and it is a very practical way to improve the seismic performance of structures in the seismic fortification of new buildings and the seismic reinforcement of existing buildings. The commonly used energy-dissipating supports in the existing passive control technology mainly include frictional energy-dissipating shock-absorbing supports, viscous and viscoelastic damper energy-dissipating sho...
