Description

Technical Field

[0001] The present invention relates to the technical field of earthquake-resistant buildings (E04B1 / 98), and in particular to a building and a design method for dual mobile end units using a single track. Background Art

[0002] In architecture, the "prefabricated frame + viscous damping" structural system is a development trend in this field. For example, "http: / / www.cnr.cn / shanghai / tt / 20180702 / t20180702_524288736.shtml" reports that viscous dampers can significantly mitigate earthquake impacts on building structures by dissipating energy and vibration through the relative motion between a piston and a cylinder. In the future, buildings will grow taller, even exceeding 100 meters. The large-scale application of viscous dampers in architecture will improve the quality of domestic buildings.

[0003] According to regulations from the Shanghai Municipal Housing and Urban-Rural Development Commission, starting in 2016, the prefabrication rate for new residential and industrial buildings in Shanghai must be no less than 40%. The use of viscous dampers can reduce the size of conventional prefabricated components, increasing the prefabrication rate to 47%, reducing concrete usage by over 7%, and lowering structural construction costs. As a result, the two buildings were recognized by the Ministry of Housing and Urban-Rural Development as "2017 Building Technology Demonstration Projects." The Lingang New Overseas Chinese Emerging Industrial Park, with a construction area of ​​approximately 206,000 square meters, comprises 24 individual buildings. Twenty-two of the buildings are 4- to 12-story R&D centers and workshops, one is a 4-story shared lobby, one is a garbage room, and a centralized underground garage is located on the first floor. All buildings were constructed using prefabricated construction technology, and five of the individual buildings were shortlisted as "Shanghai Building Demonstration Projects."

[0004] Reference: CN112832575A proposes a building using a single mobile end unit. The core structural features of the single mobile end building are: wherein, the end of the piston rod is hinged to the lower hinged plate assembly; the end connecting rod is hinged to the first cylinder of the first cylinder; wherein, the end of the connecting rod is hinged to the upper hinged plate assembly; the other end of the connecting rod is hinged to the second cylinder of the second cylinder; the track plate component is pre-set with a slotted hole, and the third cylinder is arranged in the slotted hole.

[0005] The difference between a single mobile terminal unit and a dual mobile terminal unit is not just a change in the number of mobile terminals. The inventors' research has shown that the design rules for a dual mobile terminal unit completely change. With a dual mobile terminal unit, the rules of change are even more complex. In particular, it's difficult to achieve a "variable damping" design using the same zigzag holes as with a single mobile terminal unit (that is, the zigzag holes are meaningless in a dual mobile terminal unit). However, judging by dU / dx, the dual mobile terminal unit achieves significantly higher results than a single mobile terminal unit.

[0006] However, the above-mentioned dual mobile end units use dual tracks. During the research and development process, the inventors accidentally thought of "whether it is possible to use dual mobile end units on the same track." Summary of the Invention

[0007] The object of the present invention is to provide a construction and design method of dual mobile end units using a single track, which overcomes the shortcomings of the prior art.

[0009] The single-track dual-moving unit comprises: a first hinged plate component, a second hinged plate component, a cylinder viscous damper, a cylindrical rod A, a cylindrical rod B, a plurality of parallel connecting rods A, and a plurality of parallel connecting rods B; the first hinged plate component and the second hinged plate component are both fixedly mounted on the lower surface of the upper structure;

[0010] The connection relationship between the connecting rod A and the first hinge plate component and the cylindrical rod A is: one end of the connecting rod A is hinged to the first hinge plate component, and the other end is hinged to the cylindrical rod A;

[0011] The connection relationship between the connecting rod B and the second hinge plate component and the cylindrical rod B is: one end of the connecting rod B is hinged to the second hinge plate component, and the other end is hinged to the cylindrical rod B;

[0012] The connection relationship between the cylinder viscous damper and the cylindrical rods A and B is as follows: the cylinder viscous damper includes a piston rod, a cylinder body, viscous damping fluid inside the cylinder body, and an end connecting rod; the end of the piston rod is hinged to the cylindrical rod A, and the end of the end connecting rod is hinged to the cylindrical rod B;

[0013] The "connection relationship between cylindrical rod A, cylindrical rod B and track plate components" is: two parallel track plate components are fixedly arranged on the upper surface of the lower structure, and a vertical track groove is provided on each track plate component, and the third cylinder of the cylindrical rod A and cylindrical rod B is arranged in the vertical track groove.

[0014] Furthermore, there are multiple viscous dampers in the oil cylinder, and they are arranged in parallel.

[0016] The coordinate system is established as follows: the horizontal axial direction of the beam is the X-axis, the vertical upward direction is the Y-axis; point A in the initial state is the coordinate point O, and the projection direction of point A to point B in the X-axis direction is the positive direction of the X-axis;

[0017] x B0 、y B Indicates the X-axis and Y-axis coordinates of point B in the initial state;

[0018] x D0 、y D Indicates the X-axis and Y-axis coordinates of point D in the initial state;

[0019] x max represents the maximum displacement along the positive x direction; x min Indicates the maximum displacement along the negative x direction;

[0020] L1 represents the length of the connecting rod B, that is, the length between the hinge points at both ends of the connecting rod B;

[0021] L2 represents the length of the connecting rod A, that is, the length between the hinge points at both ends of the connecting rod A;

[0022] Known: x B0 、y B 、x D0 、y D 、x max 、x min , L1, L2, the maximum length of the cylinder viscous damper is I max , the minimum length is I min , need to meet the following requirements:

[0023]

[0024] Furthermore, in the initial state, point B and point D are respectively arranged on both sides of the line formed by point A and point C (i.e., in the initial state, the hinge point between the connecting rod A and the first hinge plate component and the hinge point between the connecting rod B and the second hinge plate component are respectively on both sides of the vertical track groove).

The design of the present application is better than the design with a single movable end (but it is more difficult to implement variable damping).
