Abstract
Description
Technical Field
[0001] This application relates to the technical field of workshop environment structures, and in particular to a workshop vibration isolation trench structure. Background Technology
[0002] Vibration isolation trenches are engineering techniques used to reduce the impact of equipment vibration on the workshop environment by setting up specific trench structures around the equipment foundation to block the transmission path of vibration waves. They are based on the elastic wave scattering and energy dissipation mechanism, achieving vibration reduction by blocking the transmission path of vibration waves through trenches.
[0003] In the existing technology, the structure of the vibration isolation trench in the workshop generally adopts a U-shaped cross section. This type of vibration isolation trench needs to ensure that no objects are filled in the trench and that an air layer is maintained in order to have a good vibration isolation effect. However, in actual use, in order to facilitate workshop use, the U-shaped end face is usually filled with loose materials such as sand and gravel and slag, which leads to a deterioration of the vibration isolation effect.
[0004] Therefore, there is an urgent need to develop a new type of vehicle-mounted seismic isolation trench structure. Utility Model Content
[0005] The purpose of this application is to provide a vehicle vibration isolation trench structure to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this application provides a vehicle vibration isolation trench structure, employing the following technical solution: A seismic isolation trench structure for vehicles includes a bottom foundation layer, a middle support layer, and a top surface layer. The bottom foundation layer includes symmetrically arranged concrete foundations with a gap between the two sides of the concrete foundations. A damping layer is installed in the gap. The middle support layer includes a central damping wall and brick foundation walls symmetrically arranged on both sides of the central damping wall. The top surface layer includes symmetrically arranged concrete base layers with a damping joint between the two sides of the concrete base layers. The damping joint is filled with a deformation-resistant seismic isolation layer.
[0007] The concrete base layer is equipped with a single-layer bidirectional steel mesh.
[0008] Preferably, in order to reduce the damage to the concrete base layer on both sides of the vibration joint caused by vehicle rolling, an angle iron is installed in the concrete base layer corresponding to the vibration damping joint. The angle iron includes a horizontal part and a vertical part that are perpendicular to each other. The upper surface of the horizontal part is on the same horizontal plane as the upper surface of the concrete base layer, and the outer surface of the vertical part is on the same horizontal plane as the side wall of the anti-deformation vibration isolation layer. Multiple hooks are evenly inclined and fixed inside the angle iron, and the hooks are fixed inside the concrete base layer.
[0009] Preferably, the damping layer and the intermediate damping wall are both made of extruded polystyrene board, and the deformation-resistant isolation layer is made of asphalt-impregnated hemp fiber grease.
[0010] By adopting the above technical solutions, extruded polystyrene (XPS) boards are widely used in dry wall insulation, insulation of flat concrete roofs and steel structure roofs, moisture-proof insulation of low-temperature storage floors, under low-temperature floor radiant heating pipes, parking platforms, airport runways, highways and other fields, and control of ground frost heave. They are a cost-effective and high-quality heat insulation and moisture-proof material in the construction industry.
[0011] Asphalt-impregnated hemp fiber sealant is a waterproof sealant formed by impregnating hemp fibers with asphalt. It serves to fill, waterproof, and prevent corrosion in expansion joints and settlement joints.
[0012] The rigid structure of the seismic isolation trench is completely broken from top to bottom, and the flexible structure (asphalt hemp fiber layer and extruded polystyrene board layer) effectively blocks the propagation of seismic waves on both sides.
[0013] The damping layer and the deformation-resistant isolation layer have the same thickness, and the thickness of the intermediate damping wall is five times the thickness of the damping layer.
[0014] The bottom foundation layer and the top surface layer are at the same height, and the height of the middle support layer is five times the height of the top surface layer.
[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. The seismic isolation trench structure consists of a bottom foundation layer, a middle support layer, and a top surface layer, which together form an I-shaped cross section. The bottom foundation layer, the middle support layer, and the top surface layer are made of brick-concrete structure, which not only makes construction more convenient but also provides better structural stability and seismic isolation effect. 2. The rigid structure of the seismic isolation trench is completely broken from top to bottom, and the flexible structure (asphalt hemp fiber layer, extruded polystyrene board layer) effectively blocks the propagation of seismic waves on both sides; 3. The surface of the vibration isolation trench structure is flush with the workshop floor, which also facilitates the use of mechanical equipment in the workshop. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0020] This application discloses a vehicle separation trench structure, referring to... Figure 1 The structure includes a bottom foundation layer 1, a middle support layer 2, and a top surface layer 3. The bottom foundation layer 1 includes symmetrically arranged concrete foundations 11, with a gap between the two concrete foundations 11. A damping layer 111 is installed in the gap. The middle support layer 2 includes a middle damping wall 21 and brick foundation walls 22 symmetrically arranged on both sides of the middle damping wall 21. The top surface layer 3 includes symmetrically arranged concrete base layers 32, with a damping joint between the two concrete base layers 32. The damping joint is filled with a deformation-resistant isolation layer 31.
[0021] Both the damping layer 111 and the intermediate damping wall 21 are made of extruded polystyrene (XPS) board. XPS board is widely used in wall insulation, insulation of flat concrete roofs and steel structure roofs, moisture-proof insulation of low-temperature storage floors, under low-temperature floor radiant heating pipes, parking platforms, airport runways, highways and other fields, and to control ground frost heave. It is a cost-effective and high-quality heat insulation and moisture-proof material in the construction industry. The deformation-resistant damping layer 31 is formed by embedding asphalt-impregnated hemp fiber sealant into the damping joint. Asphalt-impregnated hemp fiber sealant is a waterproof sealant formed by impregnating hemp fibers with asphalt. It plays a role in filling, waterproofing and anti-corrosion in expansion joints and settlement joints.
[0022] The rigid structure of the seismic isolation trench is completely broken from top to bottom, and the flexible structure (asphalt hemp fiber layer and extruded polystyrene board layer) effectively blocks the propagation of seismic waves on both sides.
[0023] Reference Figure 1-2 To ensure good strength of the top surface layer 3, a single-layer bidirectional steel mesh 321 is installed inside the concrete base layer 32. Angle irons 4 are installed in the concrete base layer 32 at the positions corresponding to the vibration damping joints. Angle irons 4 include a horizontal part and a vertical part that are perpendicular to each other. The upper surface of the horizontal part is on the same horizontal plane as the upper surface of the concrete base layer 32, and the outer surface of the vertical part is on the same horizontal plane as the side wall of the anti-deformation and vibration isolation layer 31. Multiple hooks 5 are evenly inclined and fixed inside the angle iron 4. The hooks 5 are fixed inside the concrete base layer 32 and welded between the horizontal part and the vertical part. The ends of the hooks 5 have bent hooks. After the concrete solidifies, the hooks 5 can ensure that the angle irons 4 are firmly fixed to the concrete base layer 32 and will not be damaged by vehicle crushing.
[0024] Reference Figure 1 The thickness of the damping layer 111 and the deformation-resistant isolation layer 31 is the same. The thickness of the middle damping wall 21 is five times the thickness of the damping layer 111. The height of the bottom foundation layer 1 and the top surface layer 3 is the same. The height of the middle support layer 2 is five times the height of the top surface layer 3.
[0025] The implementation principle of a vehicle vibration isolation trench structure in this application embodiment is as follows: The seismic isolation trench structure consists of a bottom foundation layer 1, a middle support layer 2, and a top surface layer 3, forming an I-shaped cross-section. The bottom foundation layer 1, the middle support layer 2, and the top surface layer 3 are made of brick-concrete structure, which allows for construction using a digging and erecting method, greatly reducing construction difficulty. First, a concrete foundation 11 is poured at the bottom to ensure the compaction coefficient. Then, a brick foundation wall 22 is used to enhance the stability of the trench structure. Finally, the top surface layer 3 can also be integrated with the workshop floor, which not only provides better structural stability and seismic isolation effect, but also facilitates the use of the workshop.
[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
