Description

Technical Field

[0001] This utility model relates to the field of architectural surveying engineering technology, and in particular to a foundation for a coordinate measuring machine. Background Technology

[0002] Coordinate measuring machines (CMMs) are widely used in industries such as machinery, electronics, instrumentation, and plastics. They are one of the most efficient methods for measuring and obtaining dimensional data because they can replace various surface measuring tools and expensive combination gauges, reducing the time required for complex measurement tasks from hours to minutes. As precision instruments, CMMs are highly sensitive to ground vibration; if the installation location is subject to significant vibration, they cannot function properly. Therefore, a dedicated foundation is required to isolate them from vibration.

[0003] Please see the appendix Figure 1 In existing technology, an equipment foundation 2 is directly constructed on the structural floor slab 1, and a coordinate measuring machine (CMM) 3 is fixedly installed on the equipment foundation 2. Since the equipment foundation 2 is cast synchronously with the structural floor slab 1, vibrations from the structural floor slab 1 are directly transmitted to the CMM 3 through the equipment foundation 2, affecting the operation of the CMM 3. Furthermore, because the equipment foundation 2 is higher than the structural floor slab 1, it may require increasing the building's net height. Therefore, a CMM foundation is needed that can solve the problems of the existing technology where the equipment foundation directly transmits structural floor slab vibrations to the CMM, affecting its operation, and the problem of the equipment foundation being higher than the structural floor slab, thus increasing the building's net height. Summary of the Invention

[0004] The purpose of this utility model is to provide a foundation for a coordinate measuring machine (CMM) that can solve the problems in the prior art where the equipment foundation directly transmits the vibration of the structural floor slab to the CMM, thus affecting the use of the CMM, and where the equipment foundation is higher than the structural floor slab, thus increasing the net height of the building.

[0005] This utility model is implemented as follows:

[0006] A coordinate measuring machine (CMM) foundation includes a base layer structure, a lower CMM foundation slab, a vibration damping structure, and an upper CMM foundation slab. The base layer structure is constructed within a pre-reserved installation groove in the structural floor slab. The lower CMM foundation slab is constructed on the base layer structure, and the vibration damping structure is laid on the lower CMM foundation slab. The upper CMM foundation slab is constructed on the vibration damping structure, thus isolating the upper CMM foundation slab from the structural floor slab through the vibration damping structure. A CMM mounting groove is formed at the top of the upper CMM foundation slab, allowing the bottom of the CMM to be fitted into the mounting groove.

[0007] The aforementioned subbase structure includes a bottom subbase, a brick formwork, and side subbases. An inverted "U"-shaped installation groove is pre-reserved within the structural floor slab. The planar bottom subbase is horizontally constructed on the bottom surface of the installation groove, the annular brick formwork is circumferentially constructed on the side surface of the installation groove, and the annular side subbase is circumferentially constructed on the top side surface of the installation groove and connected to the floor slab structure. The brick formwork is connected between the edge of the bottom subbase and the inner edge of the side subbase.

[0008] The coordinate measuring machine foundation lower slab includes a bottom lower slab, a side lower slab, and a side lower slab; the bottom lower slab of the planar structure is horizontally constructed on the bottom cushion layer of the cushion layer structure, the side lower slab of the annular structure is circumferentially constructed on the inner side of the brick formwork of the cushion layer structure, and the side lower slab of the annular structure is constructed on the side cushion layer of the cushion layer structure and connected to the floor slab structure; the side lower slab is connected between the edge of the bottom lower slab and the inner edge of the side lower slab.

[0009] The top surface elevation of the lower side panel is lower than that of the top surface elevation of the structural floor slab. An annular mounting protrusion is formed on the inner ring of the top surface of the lower side panel, and the top surface elevation of the mounting protrusion is consistent with that of the top surface elevation of the structural floor slab.

[0010] The inner ring surface of the mounting protrusion is flush with the inner wall of the lower side plate, and the outer ring surface of the mounting protrusion forms a sloping structure in the direction away from the coordinate measuring machine and connects with the structural floor slab.

[0011] The vibration damping structure includes vibration damping pads and vibration damping filler. Several vibration damping pads are laid at intervals on the bottom layer of the lower layer of the coordinate measuring machine foundation, and the vibration damping filler is filled in the gaps between the vibration damping pads. The vibration damping pads and vibration damping filler are constructed on the same horizontal plane.

[0012] The coordinate measuring machine (CMM) foundation upper plate includes a bottom upper plate and a side upper plate; the planar bottom upper plate is constructed on the damping pads and damping fillers of the damping structure, and mounting holes and embedded parts are formed on the bottom upper plate; the annular side upper plate is circumferentially constructed on the inner side of the side lower plate of the CMM foundation lower plate of the CMM foundation upper plate; the bottom of the side upper plate is connected to the edge of the bottom upper plate, forming a sunken CMM mounting groove between the side upper plate and the bottom upper plate.

[0013] The top surface elevation of the upper side panel is consistent with the top surface elevation of the structural floor slab.

[0014] The top surface of the upper side plate and the top surface of the mounting protrusion both have concave structures, and fixed angle steel is installed in the concave structure by pre-embedded parts. The cover plate overlaps the upper side plate and the fixed angle steel of the mounting protrusion, so that the cover plate covers the gap between the upper side plate and the lower side plate.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] 1. This utility model has a lower base plate for the coordinate measuring machine, a shock-absorbing structure, and an upper base plate for the coordinate measuring machine. The upper base plate is isolated from the lower base plate by the shock-absorbing structure, thereby preventing the vibration force of the structural floor slab from being directly transmitted to the coordinate measuring machine fixedly installed on the upper base plate. The shock-absorbing structure has good energy dissipation and vibration reduction properties, thus ensuring the normal operation of the coordinate measuring machine.

[0017] 2. This utility model, with its subfloor structure, lower base plate of the coordinate measuring machine (CMM) foundation, shock-absorbing structure, and upper base plate of the CMM foundation, allows the entire foundation to be sunken and installed in the pre-reserved installation groove in the structural floor slab. This solves the problem in the prior art where the equipment foundation is higher than the structural floor slab, thus increasing the net height of the building. The top surface of the entire foundation is flush with the top surface of the structural floor slab, and the subfloor structure and lower base plate of the CMM foundation are connected to the structural floor slab. This results in good integrity and aesthetics between the foundation and the structural floor slab, and the foundation can be adapted to the size of the CMM. The foundation has strong load-bearing capacity, ensuring the safe and stable installation of the CMM. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Please see the appendix Figure 2 To be continued Figure 8 A coordinate measuring machine (CMM) foundation includes a base structure 4, a lower CMM foundation slab 5, a damping structure 6, and a higher CMM foundation slab 7. The base structure 4 is constructed within a pre-reserved installation groove in the structural floor slab (not shown in the figure). The lower CMM foundation slab 5 is constructed on the base structure 4, and the damping structure 6 is laid on the lower CMM foundation slab 5. The higher CMM foundation slab 7 is constructed on the damping structure 6, thus isolating the higher CMM foundation slab 7 from the structural floor slab through the damping structure 6. A CMM mounting groove 71 is formed on the top of the higher CMM foundation slab 7, allowing the bottom of a CMM (not shown in the figure) to be fitted into the mounting groove 71.

[0030] An installation slot is reserved at the installation location of the coordinate measuring machine on the structural floor slab. The entire foundation construction takes place within the reserved installation slot in the structural floor slab, allowing the coordinate measuring machine to be installed by sinking through the coordinate measuring machine installation slot 71. This avoids the problem of increasing the net height of the building due to the high pressure on the structural floor slab for equipment foundation in the existing technology.

[0031] The coordinate measuring machine (CMM) foundation lower slab 5, the vibration damping structure 6, and the CMM foundation upper slab 7 form a double-layer structure. The CMM foundation upper slab 7 is separated from the CMM foundation lower slab 5 and the structural floor slab by the vibration damping structure 6, and buffers and dissipates external forces such as vibration, thereby avoiding the problem of the structural floor slab vibration being directly transmitted to the CMM and affecting the use of the CMM.

[0032] Please see the appendix Figure 3The cushion structure 4 includes a bottom cushion 41, a brick formwork 42, and a side cushion 43; an inverted "U"-shaped installation groove is reserved in the structural floor slab; the planar bottom cushion 41 is horizontally constructed on the bottom surface of the installation groove; the annular brick formwork 42 is circumferentially constructed on the side surface of the installation groove; the annular side cushion 43 is circumferentially constructed on the top side surface of the installation groove and connected to the floor slab structure; the brick formwork 42 is connected between the edge of the bottom cushion 41 and the inner edge of the side cushion 43.

[0033] The bottom pad 41 bears vertical loads, ensuring the stability of the coordinate measuring machine's installation and operation. The brick formwork 42 bears lateral loads, reducing the impact of lateral vibrations on the coordinate measuring machine. The side pads 43 form circumferential protection around the coordinate measuring machine and are integrated with the floor structure, further reducing the impact of lateral vibrations. The pad structure 4 ensures the structural strength and load-bearing capacity of the entire foundation.

[0034] Please see the appendix Figure 4 The coordinate measuring machine foundation lower plate 5 includes a bottom lower plate 51, a side lower plate 52, and a side lower plate 53. The planar bottom lower plate 51 is horizontally constructed on the bottom pad 41 of the pad structure 4. The annular side lower plate 52 is circumferentially constructed on the inner side of the brick formwork 42 of the pad structure 4. The annular side lower plate 53 is constructed on the side pad 43 of the pad structure 4 and connected to the floor slab structure. The side lower plate 52 is connected between the edge of the bottom lower plate 51 and the inner edge of the side lower plate 53.

[0035] The bottom lower plate 51 is used to bear vertical loads, further ensuring the stability of the coordinate measuring machine's installation and operation. The side lower plates 52 are used to bear lateral loads, further reducing the impact of lateral vibration on the coordinate measuring machine. The side lower plates 53 form circumferential protection around the coordinate measuring machine and are connected to the floor structure as a whole, further reducing the impact of lateral vibration on the coordinate measuring machine. The lower plates 5 of the coordinate measuring machine foundation further ensure the structural strength and load-bearing capacity of the entire foundation.

[0036] Please see the appendix Figure 4 The top surface elevation of the lower side plate 53 is slightly lower than the top surface elevation of the structural floor slab. An annular mounting protrusion 54 is formed at the inner circle of the top surface of the lower side plate 53. The top surface elevation of the mounting protrusion 54 is consistent with the top surface elevation of the structural floor slab.

[0037] The lower side slab 53 can be concealed within the structural floor slab after its pouring, ensuring that the entire foundation does not exceed the structural floor slab, thus avoiding an increase in floor height and enhancing the aesthetics of the structural floor slab. The protrusion 54 is used for the subsequent installation of the cover plate 8. After the structural floor slab is poured, the protrusion 54 is flush with the slab, ensuring the integrity and aesthetics of the entire foundation and structural floor slab.

[0038] Please see the appendix Figure 4 The inner ring surface of the mounting protrusion 54 is flush with the inner wall of the lower side plate 52, and the outer ring surface of the mounting protrusion 54 forms a sloping structure in the direction away from the coordinate measuring machine and is connected to the structural floor slab.

[0039] The inner surface of the mounting protrusion 54 is vertical and flush with the inner wall of the lower side plate 52, avoiding interference with the installation of the upper plate 7 of the coordinate measuring machine foundation. The outer surface of the mounting protrusion 54 increases the contact area with the concrete of the structural floor slab through a sloping structure, thereby improving the reliability of the connection between the mounting protrusion 54 and the structural floor slab.

[0040] Preferably, the mounting protrusion 54 can be made of reinforced concrete and cast synchronously with the lower slab 5 of the coordinate measuring machine foundation.

[0041] Please see the appendix Figure 4 The vibration damping structure 6 includes vibration damping pads 61 and vibration damping filler 62. Several vibration damping pads 61 are laid at intervals on the bottom lower plate 51 of the foundation lower plate 5 of the coordinate measuring machine. The vibration damping filler 62 fills the gaps between the several vibration damping pads 61. The vibration damping pads 61 and the vibration damping filler 62 are constructed on the same horizontal plane.

[0042] The damping pad 61 and damping filler 62 are used to provide isolation and damping, dissipate the vibration force of the structural floor slab, and prevent the vibration force of the structural floor slab from being directly transmitted to the coordinate measuring machine, thereby ensuring the normal use of the coordinate measuring machine installed on the upper plate 7 of the coordinate measuring machine foundation.

[0043] Please see the appendix Figure 5 The coordinate measuring machine base upper plate 7 includes a bottom upper plate 72 and a side upper plate 73. The planar bottom upper plate 72 is constructed on the damping pad 61 and damping filler 62 of the damping structure 6, and mounting holes and embedded parts 74 are formed on the bottom upper plate 72. The annular side upper plate 73 is circumferentially constructed on the inner side of the side lower plate 52 of the coordinate measuring machine base lower plate 5 of the coordinate measuring machine base upper plate 7. The bottom of the side upper plate 73 is connected to the edge of the bottom upper plate 72, and a sunken coordinate measuring machine mounting groove 71 is formed between the side upper plate 73 and the bottom upper plate 72.

[0044] The bottom upper plate 72 supports the coordinate measuring machine (CMM) and is fixedly mounted on it via mounting holes and embedded parts 74, facilitating quick assembly and disassembly of the CMM. The number, structure, and arrangement of the mounting holes and embedded parts 74 can be adaptively adjusted according to the actual installation requirements of the CMM. The bottom upper plate 72 is isolated from the bottom lower plate 51 by a shock-absorbing structure 6, which effectively ensures the stable and reliable installation of the CMM on the bottom upper plate 72.

[0045] The upper side plate 73 is used to bear the lateral load, further reducing the impact of lateral vibration on the coordinate measuring machine.

[0046] The top surface elevation of the side upper layer plate 73 is consistent with the top surface elevation of the structural floor slab, ensuring that the side upper layer plate 73 is flush with the structural floor slab after construction, improving the aesthetics of the structural floor slab and avoiding the problem of increased floor height caused by equipment foundation protrusion in the prior art.

[0047] Please see the appendix Figure 7 and attached Figure 9 The top surface of the upper side plate 73 and the top surface of the mounting protrusion 54 are both formed with concave structures, and a fixed angle steel 82 is installed at the concave structure through a pre-embedded part 81. The cover plate 8 overlaps the upper side plate 73 and the fixed angle steel 82 of the mounting protrusion 54, so that the cover plate 8 covers the gap between the upper side plate 73 and the lower side plate 52.

[0048] The cover plate 8 covers the gap between the upper side panel 73 and the lower side panel 52, preventing concrete, debris, and other contaminants from falling into the gap. The recessed structure ensures that the cover plate 8 is flush with the surface of the structural floor slab after installation, guaranteeing aesthetics. Simultaneously, the embedded part 81 secures the angle steel 82, facilitating the lap welding of the cover plate 8 onto the angle steel 82 and ensuring a firm and reliable installation.

[0049] Please see the appendix Figure 2 To be continued Figure 9 The construction process of this utility model is as follows:

[0050] At the installation location of the coordinate measuring machine, the bottom cushion layer 41, the brick formwork 42, and the side cushion layer 43 are constructed sequentially. The bottom cushion layer 41 and the side cushion layer 43 can be formed by concrete pouring, and the brick formwork 42 can be formed by brick masonry, forming the cushion layer structure 4.

[0051] A bottom lower slab 51 is constructed on the bottom cushion layer 41. A side lower slab 52 is constructed on the inner side of the brick formwork 42 and the edge of the bottom lower slab 51. A side lower slab 53 is constructed on the outer side of the side lower slab 52 and on the side cushion layer 43. A mounting protrusion 54 with a right-angled trapezoidal cross-section (narrower at the top and wider at the bottom) is circumferentially provided at the inner edge of the side lower slab 53. The bottom lower slab 51, side lower slab 52, side lower slab 53, and mounting protrusion 54 can be constructed of reinforced concrete and cast as a single unit to form the foundation lower slab 5 of the coordinate measuring machine.

[0052] Vibration damping pads 61 are laid at intervals on the bottom lower plate 51, and the gaps between the vibration damping pads 61 are filled with vibration damping filler 62 to form a vibration damping structure 6. The vibration damping pads 61 can be made of rubber, and the vibration damping filler 62 can be yellow sand, which is compacted when filling.

[0053] A bottom upper plate 72 is constructed on the vibration damping structure 6. A side upper plate 73 is constructed on the edge of the bottom upper plate 72 and the inner side of the side lower plate 52. The bottom of the side upper plate 73 is connected to the edge of the bottom upper plate 72 to form a coordinate measuring machine foundation upper plate 7 with a coordinate measuring machine mounting groove 71. The bottom upper plate 72 and the side upper plate 73 can be made of reinforced concrete and cast as a whole to form the coordinate measuring machine foundation upper plate 7.

[0054] Mounting holes and embedded parts 74 are reserved on the bottom upper plate 72 according to the installation requirements of the coordinate measuring machine.

[0055] A cover plate 8 is installed between the top surface of the mounting protrusion 54 and the top surface of the side upper plate 73 by means of a pre-embedded part 81, and the top surface of the fixed angle steel 82 is connected to cover the gap between the side upper plate 73 and the side lower plate 52.

[0056] The structural floor slab is constructed, connecting to the mounting protrusion 54 and the lower side slab 53, with the top surface of the structural floor slab flush with the top surface of the upper side slab 73, forming a unified foundation with the structural floor slab. The bottom of the coordinate measuring machine (CMM) is installed into the CMM mounting slot 71 and secured with mounting hardware via mounting holes and embedded parts 74, ensuring a firm and reliable installation. The CMM is ready for use after installation.

[0057] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
