Shock-proof bundled energy clearing slope support

Abstract

The inclined piece is composed of main stress unit and tying and binding unit mainly. The main stress unit is composition of steel members possessing mono symmetrical or bisymmetric sections in any shapes in open or close types. Sections at end parts larger than section at middle part are sheathed to the tying and binding unit. Being assembled from components of single or multiple steel tubes with concrete, sand-cement slurry or stiffened members being filled or installed inside tubes, the tying and binding unit as a body of outline border is in use for tying and binding the main stress unit. Being matched to end part of the inclined piece in modes of lap joint or socket joint, the tying and binding unit is connected to structure. The inclined piece is steady no mater stress or pull are applied. The disclosed inclined piece increases capability of anti plastic deformation so as to reach effect of reducing vibration and earthquake force.

Description

technical field [0001] The invention relates to a building material component, in particular to an anti-seismic bundle energy-dissipating diagonal brace which can improve the plastic deformation capacity of the diagonal brace, reduce vibration and earthquake force. Background technique [0002] When the traditional diagonal bracing member is subjected to axial pressure, it will produce overall deformation and local deformation, and its hysteretic curve shows the behavior of gradually decreasing strength and shrinkage. Concentrated and broken. Over the years, earthquake engineering researchers have started to improve the performance of traditional diagonal braces, and some units have successively published bundled braces that can prevent deformation to replace and improve the function of traditional diagonal braces. [0003] see figure 1 As shown, the braced brace is composed of the main stress unit 11 and the brace unit 12, the axial force (tension and compression) of the ...

[0006] However, this butt joint method not only increases a large number of joint welding operations, but also makes the joint part quite complicated and crowded; in addition, under the premise that the joint transmits an equal amount of axial force, the bolts required for the butt joint are used Quantity will be double that with lap joints

As a result, when installing this kind of brace, it may be very labor-intensive and time-consuming, the work efficiency will be reduced, and the quality will not be easy to control

[0007] see Figure 2~4 As shown, some people have researched and proposed a plug-in energy-dissipating diagonal brace. Although this plug-in energy-dissipating diagonal brace reduces the use of bolts and the use of butt steel plates, this plug-in energy-dissipating diagonal brace The cross-section configuration of the brace is to insert two strip-shaped steel plates 21 of equal cross-section with a fixed parallel distance into a bundle unit 22 composed of a steel pipe and concrete. The distance between the strip-shaped steel plates 21 is not easy to locate, nor is it easy to control its precision, and the installation of the plug-in joint surface 23 and the joint corner plate 24 is directional. If the distance between the two strip-shaped steel plates 21 is positioned Poor, and if the length of the diagonal brace is often greater than the beam span or column height when it is installed in a single oblique direction, the installation efficiency will definitely be reduced, and it will even be impossible to insert and install
