Description

An intelligent support system

technical field

The utility model belongs to the technical field of anti-seismic and structural vibration control of civil engineering such as buildings and bridges, and relates to an intelligent bearing system.

Background technique

The support is an important node component used to connect the upper structure and the lower structure in the building structure and bridge structure. It must have sufficient bearing capacity to ensure the safe and reliable transmission of the support reaction force, including vertical pressure, tension and horizontal shear force. ; The constraints on the displacement and corner deformation of the upper structure must be as small as possible to meet the needs of free expansion and rotation of the upper structure, and the support should also be easy to install, maintain and repair.

my country is an earthquake-prone country with vast and scattered earthquake areas and frequent and strong earthquakes. Since 1900, there have been 12 strong earthquakes with a magnitude equal to or greater than 8. Among them, those that occurred in densely populated places caused heavy damage, such as the Tangshan earthquake on July 28, 1976, and May 12, 2008. Wenchuan Earthquake. The survey of actual earthquake damage shows that: the failure of node support is one of the most common failure forms that lead to the failure of building structures or superstructures of bridge structures. Under the action of earthquake, the seismic damage of the support joints mainly shows that the support is tilted and sheared; the anchor bolts are pulled out; the sliding support falls off and the structural damage of the support itself. At the same time, in the daily use of buildings, bridges and other structures, structural damage and collapse accidents caused by the quality problems of the bearings also occur from time to time. collapse under stress.

Once the support as an important node in the structure fails, it will lead to changes in the force transmission mode in the structure, which will adversely affect the seismic performance of other parts of the structure and further aggravate the structural damage or earthquake damage. In the past, the safety evaluation of bearings was carried out by dismantling and inspecting one by one. This is a time-consuming and laborious method for large-scale projects, and it is difficult to know the damage of bearings in time after an emergency.

Utility model content

The technical problem to be solved by the utility model is to provide an intelligent support system capable of monitoring the health status of the support in real time.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

An intelligent support system is composed of a support embedded with intelligent sensing materials, a data acquisition instrument 10 and a monitor 11; the support embedded with intelligent sensing materials is composed of a three-way displacement sensor 2, a load cell 3, an upper The bearing plate 4, the plane stainless steel plate 5, the plane slide plate 6, the spherical crown lining plate 7, the spherical slide plate 8 and the load-bearing body 9 are composed of the upper part of the load-bearing body 9 inserted into the slotted part of the lower part of the upper bearing plate 4, and the top of the load-bearing body 9 is provided with A circular groove, one side of the spherical crown lining plate 7 is a plane, and the other side is an arc surface, the arc surface of the spherical crown lining plate 7 is located in the groove of the bearing body 9 through the spherical slide plate 8, the plane of the spherical crown lining plate 7 There is a groove partly, and the plane slide plate 6 is embedded in the groove, and the top of the plane slide plate 6 is connected to the slotted part of the upper bearing plate 4; There is a three-way displacement sensor 2, and a force sensor 3 is provided at the connection between the bearing body 9 and the spherical slide 8; the three-way displacement sensor 2 and the force sensor 3 are respectively connected to the data acquisition instrument 10, and the output end of the data acquisition instrument 10 is connected to the monitoring Device 11.

In the present utility model, the quantity of the three-way displacement sensor 2 is two.

In the utility model, described monitor 11 adopts the computer that installs the monitoring software program that assembler language Visual Basic writes.

The beneficial effect of the utility model is that: the intelligent bearing system provided by the utility model can monitor the stressed state (including force, deformation, etc.) The defect of the unknown stress state of the support further avoids the sudden damage of the support as an important node in the structure under the action of use or strong earthquake, which is conducive to improving the safety of the structure, has high practical value and economic benefit, and can be widely used in The daily use of civil engineering structures such as buildings and bridges releases temperature deformation and design requirements such as earthquake resistance and wind resistance.
