Problems solved by technology

In the process of application and popularization of these two technologies, the primary difficulty is still the cost
The existing theoretical analysis and experimental research show that the use of these two technologies can improve the seismic performance of the structure, but in the engineering practice of our country, the problem exposed is that compared with the traditional seismic system, the two technologies are in No advantage in terms of cost

Embodiment 1

[0034] Example 1: see image 3 . The middle part of the X-shaped reinforced concrete member 1 has an upper platform 2 and a lower platform 3, and there is a space between the two. There are two energy dissipating units, and each dissipating unit is provided with three steel plates 4 and two rubber sheets 5 clamped in the steel plates 4 at intervals. The fastening force applying mechanism of each energy dissipator unit is two bolts 6 vertically passing through the upper platform 2 of the reinforced concrete bar 1 and one end of which can press against the uppermost steel plate 4 . A steel plate 7 is pre-embedded in the lower platform 3 of the reinforced concrete member, and the lowermost steel plate 4 in each energy dissipation unit is directly welded and fastened to the pre-embedded steel plate 4 . 8 in the figure is the embedded steel plate embedded in the upper platform 2, and the bolt 6 also passes through the embedded steel plate 8. In this embodiment, when on-site inst...

Embodiment 2

[0035] Example 2: see Figure 4 . An energy consumer unit is installed, and the energy consumer unit is provided with three steel plates 9 and two rubber sheets 10 clamped between the steel plates 9 . The fastening force applying mechanism of the energy dissipator unit is three bolts 11 that vertically pass through all the steel plates 9 and rubber sheets 10 and can be tightened. A steel plate 12 is pre-embedded in the lower platform 3 of the reinforced concrete member 1, and the extension of a steel plate 9 in the middle of the energy dissipation unit is fastened to the pre-embedded steel plate 12 with a large bolt 12 . 13 in the figure is the pre-embedded steel plate embedded in the upper platform 2, one end of the two connecting steel parts 14 is fastened to the steel plate 9 of the energy dissipation unit, and the other end is welded and fastened to the pre-embedded steel plate 13. In this embodiment, the vertical tightening force is applied to the steel plate and the ru...

Embodiment 3

[0036] Embodiment 3: see Figure 5 . The energy dissipator unit has two upper and lower steel plates 15, a middle steel plate 19, and two rubber sheets 16 respectively clamped between the three steel plates. The fastening force applying mechanism of the energy dissipator unit is four bolts 17 that vertically pass through the upper and lower two steel plates 15 and can be tightened. The extended part of the middle steel plate 19 is provided with two notches, and the two sides of the main body of the energy dissipation unit are also provided with two notches, and correspondingly equipped with four fastening steel plates 18 that can be embedded in the above four notches , one end of each steel plate 18 has a slope. When installing the energy dissipator unit, insert the fastening steel plate 18 into the corresponding notch, with the slopes of the two steel plates 18 facing upwards and the slopes of the two steel plates 18 facing downwards, and respectively connect the top of the...

Abstract

The invention relates to a damping method with low cost and energy consumption, relative device and method, wherein the invention uses X-shape steel bar concrete rod as support element; uses steel plate clamp rubber sheet as friction energy consumer; connects four ends of steel bar concrete rod to the beam nodes of building frame; in said energy consumer, functions some fixing force on the steel plate of clamp rubber sheet, to generate stable friction between the rubber sheet and steel plate as the starting force of energy consumer that absorbs output kinetic energy; and adjusts the fixing force to adjust the starting force. The invention has low cost, high appearance, simple production and easy operation. Compared with traditional structure, the concrete and steel bar consumptions are reduced most.

Description

technical field [0001] The invention belongs to the field of anti-seismic technology of buildings. Background technique [0002] As we all know, in high-intensity earthquake areas, after the building height reaches a certain level, the frame structure commonly used in multi-storey buildings can no longer meet the requirements of earthquake resistance. The traditional solution is to use frame-shear wall, shear wall, frame-tube and other structural forms, the common feature of which is to use reinforced concrete anti-seismic wall as the main anti-lateral force member to meet the needs of structures under earthquake action. strength and stiffness requirements. Over the years, this solution has been widely recognized and adopted in engineering practice, and has also experienced the test of small earthquakes to strong earthquakes. Do not fall" required. However, with the continuous improvement of the level of social and economic development, the characteristics of the losses c...
