Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a vibration isolation foundation structure for an XPS electron microscope laboratory room. Background Art

[0002] Most modern electron microscopes use electromagnetic lenses. The strong magnetic field generated by a very stable DC excitation current through a coil with a pole shoe focuses the electrons. Since the electron scattering ability is extremely strong, secondary diffraction is prone to occur. Therefore, the electron microscope laboratory has relatively high requirements for the anti-magnetic properties of the room. At the same time, the experimental process of the electron microscope laboratory is extremely precise and has relatively high requirements for the environment. The electron microscope is a high-precision electronic instrument. From the perspective of instrument maintenance, the instrument has high requirements for the room temperature. If the space control of water vapor is not in place, it will affect the accuracy of the experimental results at the least, and even cause instrument failure and reduce the service life.

[0003] In terms of working performance, the electron microscope always maintains high precision during operation. It is required that after the transformation, under the condition that other environments maintain normal operation of the equipment, the vibration value at the 0-100Hz frequency band of one-third times the frequency point in three orthogonal directions on the ground corresponding to the electron microscope tube to be placed is less than or equal to the value of the corresponding frequency point before the transformation. Therefore, the stability and relative independence of the room are particularly important. Slight vibration may affect the clarity of the instrument results.

[0004] In summary, in addition to meeting the basic load conditions of the equipment room, the on-site construction unit must also take into account anti-magnetic and anti-micro-vibration, and strictly control the room temperature and humidity. Conventional vibration isolation foundations cannot meet the high stability requirements of the XPS electron microscope laboratory.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art. Utility Model Content

[0006] In order to overcome the defects of the prior art, a vibration isolation foundation structure for an XPS electron microscope laboratory room is provided to solve the problem that the conventional vibration isolation foundation cannot meet the high stability requirements of the XPS electron microscope laboratory.

[0007] To achieve the above object, a vibration isolation foundation structure for an XPS electron microscope laboratory room is provided, comprising:

[0008] The beneficial effect of the utility model is that the first-level foundation plate in the vibration isolation foundation structure for the XPS electron microscope laboratory room of the utility model is connected to the raft plate, and the flaps are made around to form a accommodating groove, and the second and third-level foundation plates are wrapped inside. The first-level foundation plate mainly plays the role of stabilizing the whole and carrying the upper structure. Secondly, the first, second and third-level foundation plates are treated with seismic joints to separate each level of foundation into an independent individual. A certain space is reserved between the foundations of each level to avoid mutual interference between the rooms. At the same time, coarse sand and ceramsite materials are added between the first-level foundation plate and the second and third-level foundation plates, and the entire system is transformed into a sliding support system, which reduces friction, reduces vibration transmission, and allows the room to have a certain displacement space in the lateral direction, thereby ensuring that each level of foundation is relatively independent, effectively reducing the impact between the entire system and the individual room, and the system reduces the impact of the room under the action of external forces from the lateral force. The vibration isolation foundation structure for the XPS electron microscope laboratory room of the utility model increases the overall resistance performance of the mechanism, enhances the stability of the structure, and creates an independent system in the structure.

[0016] Reference Figures 1 to 4As shown, the utility model provides a vibration isolation foundation structure for an XPS electron microscope laboratory room, comprising: a primary foundation plate 1, a secondary foundation plate 2, a small frame structure 3, a tertiary foundation plate 4, and shock-absorbing granular materials 5.

[0017] Combination Figure 1 and Figure 4 As shown, the main structure raft slab 7 is formed with a first hole arranged vertically. The primary foundation slab 1 is cast in the first hole. A first gap is formed between the periphery of the primary foundation slab 1 and the hole wall of the first hole. The primary foundation slab is relatively independent from the main structure raft slab.

[0018] A receiving groove is formed on the upper part of the primary foundation plate 1. Support piles are driven into the soil below the primary foundation plate 1. The support piles are supported on the primary foundation plate 1.

[0019] In this embodiment, the bottom of the support pile is embedded in the rock layer of the soil below the first-level foundation class.

[0020] The secondary base plate 2 is arranged in the receiving groove. A second hole arranged vertically is formed in the secondary base plate 2. A second gap is formed between the secondary base plate 2 and the groove wall of the receiving groove.

[0021] The small frame structure 3 is cast on the secondary foundation plate 2.

[0022] Specifically, the small frame structure 3 includes a plurality of first frame columns 31 and a first frame beam 32. The plurality of first frame columns 31 are arranged along the circumferential direction of the second hole. The first frame beam 32 is connected to the plurality of first frame beams 32.

[0023] The third-level base plate 4 is arranged in the second hole. A third gap is formed between the third-level base plate 4 and the hole wall of the second hole. The third-level base plate 4 is used to install the electron microscope equipment.

[0024] Shock-absorbing granular materials 5 are respectively arranged in the bottom of the accommodating groove, the second gap and the third gap.

[0025] As a preferred embodiment, the shock-absorbing granular material 5 includes coarse sand and ceramsite.

[0026] Furthermore, the first gap may also be filled with damping granules.

[0027] The vibration isolation foundation structure for the XPS electron microscope laboratory room of the utility model further comprises a large frame structure 6 .

[0028] The raft 11 is cast at the bottom of the primary foundation plate 1. The large frame structure 6 includes a plurality of second frame columns 61 and a second frame beam 62. The plurality of second frame columns 61 are cast on the outer edge of the raft. The second frame beam 62 is connected to the plurality of second frame columns 61. The top elevation of the second frame column 61 is higher than the top elevation of the first frame column 31.

[0029] In this embodiment, in order to prevent micro-vibration and anti-vibration characteristics of the electron microscope laboratory, the vibration isolation foundation structure used for the XPS electron microscope laboratory room of the utility model adopts a three-level vibration isolation foundation to maintain the overall stability of the structure and ensure the relative independence of the room.

[0030] Perform an overall stress analysis on the entire building structure, keep its frame structure unchanged, and increase the stability of the structure itself. The stability of the structure is divided into horizontal stability and vertical stability. The focus of structural stability is the stability of the building in the vertical direction. The vertical stress of the building mainly comes from the building itself and the load generated to meet the use requirements. In the actual operation process of construction, in order to enhance the vertical stability, the usual solution is to increase the bearing capacity of the foundation, set separation seams and other basic measures. The vibration isolation foundation structure of the XPS electron microscope laboratory room of the utility model adopts a pile foundation raft foundation for the first-level foundation plate to ensure the stability of the building structure. While enhancing the lower bearing capacity, it disperses the building's own load and avoids the impact of uneven settlement on the building.

[0031] The vibration isolation foundation structure of the XPS electron microscope laboratory room of the utility model, while satisfying the basic vertical stability, also needs to consider the horizontal direction influence, especially the mutual interference between two adjacent rooms, and adopts a three-level foundation to solve it. The first-level foundation plate is connected to the pile foundation raft foundation, the second-level and third-level foundation plates are within the first-level foundation plate, and the three foundation plates constitute an integral structure. The contact points are filled with materials such as expanded clay to ensure that the three foundation plates are independent of each other and do not affect each other, thereby ensuring the anti-interference performance of the structure in the horizontal direction.

[0032] The vibration isolation foundation structure of the XPS electron microscope laboratory room of the utility model adopts a pile foundation raft foundation. The relatively high-density pile foundation is embedded in the rock layer, which increases the rigidity of the entire building system, provides reliable support for the building, and generally reduces the settlement of the building. The raft foundation can reduce the uneven settlement of the building and reduce the microscopic changes in the building. The two systems are combined to provide doubly insured for the system of the building itself, maintain the stability of the entire system, disperse the load in the building, and reduce the influence of the building itself and the outside world on the entire system.

[0033] The utility model is used for the first-level foundation plate in the vibration isolation foundation structure of the XPS electron microscope laboratory room, and the first-level foundation plate is connected to the raft plate, and the flaps are formed around to form a containing groove, and the second and third-level foundation plates are wrapped inside. The first-level foundation plate mainly plays the role of stabilizing the whole and carrying the upper structure. Secondly, the first, second and third-level foundation plates are treated with earthquake-resistant joints to separate each level of foundation into an independent individual, and a certain space is reserved between the foundations of each level to avoid mutual interference between the rooms. At the same time, coarse sand and expanded clay materials are added between the first-level foundation plate and the second and third-level foundation plates to change the entire system into a sliding support system, reduce friction, alleviate vibration transmission, and allow the room to have a certain displacement space in the lateral direction, thereby ensuring that each level of foundation is relatively independent, effectively reducing the impact between the entire system and the individual room, and the system reduces the impact of the room under the action of external forces in terms of lateral force.

[0034] The utility model provides a vibration isolation foundation structure for an XPS electron microscope laboratory room, which increases the overall resistance performance of the mechanism, enhances the structural stability, and simultaneously creates an independent system within the structure to avoid "a single move affecting the entire body".

[0035] The utility model is used for the vibration isolation foundation structure of the XPS electron microscope laboratory room. Glass fiber reinforcement (GFRP) is a kind of fiber reinforced composite material. The fiber reinforced composite material is a material formed by high-performance fiber, synthetic resin matrix and curing agent using appropriate molding process; high-performance fiber is the reinforcing material and synthetic resin is the matrix material. Fiber has high tensile strength and is the main provider of strength of fiber reinforced composite materials. It mainly plays the role of bearing load. It is mainly divided into carbon fiber, aramid fiber, basalt fiber, glass fiber, etc. The matrix material has the function of bonding and transmitting shear force, and its physical properties can affect the physical properties of fiber reinforced materials. Its characteristics include the characteristics of glass fiber reinforcement: high load-bearing capacity, strong tensile capacity, the rod strength is twice that of threaded steel bars of the same diameter, but the mass is only 1 / 4 of steel bars; the elastic modulus is stable, about 1 / 3 to 2 / 5 of steel bars; electric and thermal insulation, the thermal expansion coefficient is closer to cement than steel bars.

[0036] The vibration isolation foundation structure used in the XPS electron microscope laboratory room of the utility model should pay attention to its characteristics during the construction process, namely, anti-magnetic and anti-micro-vibration. The characteristics of the glass fiber reinforcement can be highly compatible, while increasing the overall performance of the structure, reducing the self-load of the building, greatly improving the stability of the building. Secondly, the glass fiber reinforcement is electrically and thermally insulated, which can avoid the influence of electromagnetics during the operation of the electron microscope laboratory, and can also prevent electromagnetics from being transmitted to the foundation system through the steel bars, thereby interfering with the electromagnetic stability of the entire building.

[0037] The vibration isolation foundation structure of the XPS electron microscope laboratory room of the utility model is of great significance in modern times. Its working conditions are relatively harsh. During the construction process, its main characteristics, namely, anti-magnetic and anti-micro-vibration, must be always grasped for the electron microscope laboratory.

[0038] In order to prevent micro-vibration in electron microscope laboratories, the vibration isolation foundation structure for XPS electron microscope laboratory rooms of the utility model first increases the macroscopic stability of the frame structure and reduces the unstable factors caused by self- or external interference. The vibration isolation foundation structure for XPS electron microscope laboratory rooms of the utility model adopts pile foundation raft foundation for structural stability to increase the vertical bearing capacity of the building.

[0039] Secondly, in order to strictly control the vibration isolation effect of the room, the building still needs to be regulated at the micro level. For the micro-vibration of the room, the vibration isolation foundation structure used in the XPS electron microscope laboratory room of the utility model adopts a three-level vibration isolation foundation, and the first-level foundation plate and the second and third-level foundation plates are made into a sliding support system, which reduces the interference of vibrations generated by the building itself on the electron microscope laboratory, and greatly improves the stability of the electron microscope laboratory.

[0040] Regarding anti-magnetic measures, the vibration isolation foundation structure of the XPS electron microscope laboratory room of the utility model fully considers its characteristics and replaces the traditional reinforcement of the structure with glass fiber reinforcement, which not only increases the structural stability but also effectively reduces the conduction of indoor electromagnetic radiation into the building through the foundation.

[0041] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical solution.
