Embodiment 1

[0021] Embodiment 1: as figure 1 Shown is an embodiment of a new masonry structure device of the present invention that can resist the impact of debris flow, which mainly includes a steel grid 1 , a damping sandwich layer 2 , a nonlinear damping alloy sheet 3 and a rubber pad 4 .

[0022] The device is installed on the side elevation of the masonry exterior wall, and the outermost layer is a steel grid mesh 1, which is fixed to the floor slab and the foundation by means of cables or the like. Between the steel grid mesh 1 and the side elevation of the masonry exterior wall is a damping sandwich layer 2, and the damping sandwich layer 2 is equidistantly intersected with holes, and the cross-section of the holes is square, which is used to install the nonlinear damping alloy sheet 3. A rubber pad 4 is arranged between the nonlinear damping alloy sheet 3 and the outer facade of the masonry wall. Square holes are spaced three times the hole size. The length and width of the nonl...

Abstract

The invention relates to a novel masonry structure device capable of resisting debris flow impact. The novel masonry structure device capable of resisting debris flow impact comprises a steel grid network, a damping sandwich layer, non-linear damping alloy sheets and rubber cushion blocks. The device is wrapped outside a wall body of a masonry structure, and the steel grid network is connected with a foundation and a floor plate through modes of an inhaul cable and the like. The damping sandwich layer is arranged between the steel grid network and the wall body, a plurality of square holes are formed in the damping sandwich layer, and a non-linear damping alloy sheet and a rubber cushion block are arranged in each square hole. The steel grid network intercepts the debris flow to avoid a horizontal fury impact on the masonry structure under the impact effect of the debris flow. Because the steel grid network bears giant impact force, the steel grid network is deformed, and squeezes the non-linear damping alloy sheets and the damping sandwich layer. The non-linear damping alloy sheets are buckled and then absorb the impact energy, and alloy sheet buckling has the characteristic of sharp declination of rigidity to have a buffering effect on the masonry structure. The novel masonry structure device has a good protective effect on the masonry structure, so that horizontal impact resistance performance of the masonry structure is obviously improved.

Description

technical field [0001] The invention relates to a new masonry structure device that can resist the impact of debris flow. Steel grids, damping sandwich layers and nonlinear damping alloy sheets are arranged on the outer facade of the masonry structure. Under the impact of debris flow, the steel grids directly Under the impact of debris flow, the impact energy is absorbed by the deformation of the damping sandwich layer and the buckling of the nonlinear damping alloy sheet, which plays a good role in protecting the masonry structure, and belongs to the field of disaster prevention of civil engineering structures. Background technique [0002] In the field of disaster prevention, debris flow is a natural disaster that cannot be ignored. Debris flows occur frequently in mountainous areas with low vegetation coverage. Our country has a vast territory and a large area of ​​mountains. In addition, the terrain is complex and the tectonic movement is strong. Debris flows are very p...
