Abstract
The utility model discloses a damper. The damper is a steel plate, a circular hole is formed on the steel plate, two sides of the steel plate are in a shape of a concave arc, and the two concave arc shaped sides are opposite. According to the damper disclosed by the utility model, the principle that the plane of the steel plate is stress yielded is used, and a simple construction mode is adopted; the damper in a shape of Chinese character Hui disclosed by the utility model can be obtained by directly cutting the steel plate, and the damper is convent to machining and manufacturing, easy to be massively produced and relatively low in cost.
Description
Technical field
The utility model relates to a kind of auxiliary part for building, is specifically related to a kind of damper.
Background technology
Damper in the building can directly absorb seismic energy, when earthquake occurs, the geological process power that acts on the building at first acts on the energy-consumption damper, reasonably damper arrangement can consume mostly brisance, the geological process power that acts directly on like this on the building will greatly reduce, reduce structure shift, improved significantly the anti-seismic performance of building.
Existing damper can be divided into two kinds according to the difference of power consumption principle: a kind of the equal thickness place surrenders earthquake energy simultaneously outside the damping steel plate plane in order to utilize; Another kind of for utilizing stressed surrender power consumption in the damping steel plate plane.
Using at present more be the first, and the initial stiffness of this damper is very little, easily is out of shape, and supporting capacity is lower, and will change this situation, the quantity of increase damper that will be artificial, so that implement unusual inconvenience, and extremely uneconomical.The second damper has higher initial stiffness, can strengthen integrally-built stability, yield strength is larger, can consume more geological process power, but existing the second metal damper structure is more complicated all, in processing and making process, easily produce error, thus subjective impact the energy-dissipating property of metal damper.
Summary of the invention
For defective or the deficiency of prior art, the purpose of this utility model is to provide that a kind of processing cost is low, simple in structure, the damper of reasonable stress.
For realizing above-mentioned technical assignment, the utility model is taked following technical solution:
A kind of damper is characterized in that, this damper is a steel plate, offers circular hole on this steel plate, and it is concave arc shape that two sides are arranged on the steel plate, and two concave arc shape sides on the steel plate are relative.
Described steel plate is square shape steel plate or oblong-shaped steel plate.
The side of intersecting with the concave arc shape side of described steel plate is plane.
Damper of the present utility model utilizes the principle of stressed surrender in the steel plate plane, adopts simple make, steel plate is directly cut just can obtain three-back-shaped damper of the present utility model, and processing and fabricating conveniently is easy to produce in enormous quantities, and cost is lower.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the damper mounting structure schematic diagram under construction of embodiment.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.
Specific implementation method
With reference to figure 1, according to the technical solution of the utility model, the damper of this embodiment is a square steel plate 1, offer circular hole 2 on this steel plate 1, and it is concave arc shape that two sides are arranged on this steel plate 1, and the side of two concave arc shapes is relative, and the side of intersecting with concave arc shape side 3 of steel plate 1 is plane.
The damper material therefor of this embodiment is Q235, specifically is of a size of the steel plate length of side: 600mm, circle hole radius: 210mm, the radius of side concave arc: 450mm; The thickness of damper of the present utility model is indefinite, and the damper of different-thickness has energy dissipation capacity in various degree, can select the damper of suitable thickness to add in the structure according to actual conditions in engineering, and the damper thickness of this embodiment is 10mm.
With reference to figure 2, the damper of this embodiment is used for having the frame wall filled with masonry of weak floor, during Specific construction, build first beam column frame 5; Then damper 4 is joined with beam by supporting 6, support 6 and can adopt inverted v-shaped or 1 font, damper 4 can adopt Type of Welding with contact of beams; Build at last infilled wall by laying bricks or stones.
From structure, the circular opening in the middle of the damper can well be avoided under the geological process power damper to produce stress concentrating; Because geological process power is level, the damper left and right sides are the circular-arc surrender power consumption that is easier to; Damper up and down the side be the plane convenient with being connected of beam, support.
Be equipped with the framework of this damper structure, the convex structure of damper the right and left is first stressed when earthquake occurs, and plane internal deformation occurs, the surrender power consumption, and then the destructive power that acts on the framework will reduce.
Impaired in earthquake such as damper, as can more to renew under the prerequisite that does not change former frame construction damper conveniently plays the repair of shake post-reinforcing effectively.
Claims (3)
