Description

Technical Field

[0001] This invention relates to the field of equipment installation and construction technology, and specifically to a construction method in which the stress point of the equipment falls in the core stress area of ​​the equipment foundation. Background Technology

[0002] During the installation of various equipment such as industrial equipment and heavy machinery, whether the stress points of the equipment can be accurately located in the core stress area of ​​the equipment foundation directly determines the stress stability of the foundation and the long-term operational safety of the equipment. Traditional equipment installation methods often involve directly fixing the equipment to the foundation. However, existing equipment installation methods have the following shortcomings in practice:

[0003] 1) Traditional installation methods directly fix the equipment foundation, which cannot effectively adjust the position of the equipment's stress points and is difficult to adapt to the equipment foundation design or equipment installation position. Especially when there are deviations in the equipment foundation design or equipment installation position, the equipment's stress points may not fall accurately in the core stress area. This may lead to uneven stress on the equipment foundation, increasing the risk of equipment foundation cracking and failure, thereby affecting the safe operation and service life of the equipment.

[0004] 2) When the stress point of the equipment deviates from the core stress area, the uneven stress on the equipment foundation may lead to foundation damage and unstable equipment operation, potentially causing safety hazards.

[0005] 3) When equipment is upgraded, the new equipment size and stress characteristics are often incompatible with the original equipment foundation. Traditional installation methods require the reconstruction of the equipment foundation, which not only increases project costs but also prolongs the construction period and affects production progress. Summary of the Invention

[0006] The technical problem this invention aims to solve is to address the shortcomings of existing technologies by providing an extendable support frame assembled from an outer component and two inner components. This support frame allows for flexible length adjustment, enabling precise adjustment of the equipment's stress point position. It can adapt to various scenarios, including deviations in equipment foundation design and installation location, ensuring that the stress point always falls within the core stress area of ​​the foundation. This improves equipment installation flexibility, ensures uniform stress on the foundation, reduces safety hazards, and saves on foundation modification costs.

[0007] Construction methods.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A construction method for placing the stress point of the equipment in the core stress area of ​​the equipment foundation, the construction method comprising the following steps:

[0010] Step S1) Determine the core stress area of ​​the equipment foundation for the equipment to be installed: Based on the length X and width Y of the equipment foundation, calculate the range of the core stress area of ​​the equipment in the X direction of the equipment foundation as 70%X to 85%X, and calculate the range of the core stress area of ​​the equipment in the Y direction of the equipment foundation as 70%Y to 85%Y. The distance between the edge of the equipment support and the side of the equipment foundation shall not be less than a set threshold, and the equipment support shall not be located at the four corners of the equipment foundation. The equipment support shall be symmetrically arranged along the center line of the equipment foundation, and the support surface shall cover more than a set proportion of the bottom area of ​​the equipment.

[0011] Step S2) Fabricate the outer layer component: Based on the distance between the two stress points of the equipment in the Y direction, fabricate the outer layer component and reserve the first bolt positioning hole on it;

[0012] Step S3) Fabricate inner layer components: Determine the length of the inner layer components based on the shortest distance from the stress point of the equipment to the core stress area, and reserve second bolt positioning holes on the inner layer components;

[0013] Step S4) Assemble the extension bracket: Insert the two inner layer components into the outer layer components from both ends and connect and fix them with high-strength bolts to assemble an adjustable length extension bracket.

[0014] Step S5) Adjust the position of the equipment stress point: Place the outer component on the equipment foundation, loosen the high-strength bolts, adjust the depth of the two inner components extending into the outer component, so that the ends of the two inner components away from the outer component are accurately located in the stress core area of ​​the equipment foundation, and then fix the inner component and the outer component with high-strength bolts.

[0015] Step S6) Install H-beam steel components: Lay several spaced spring shock absorbers above the equipment foundation, hoist the H-beam steel components to the top of the spring shock absorbers, so that the web of the H-beam steel components is perpendicular to the surface of the equipment foundation, and fix the assembled and adjusted extension bracket above the H-beam steel components.

[0016] Step S7) Fix the equipment: Fix the equipment above the extension bracket and lay a rubber shock-absorbing pad between the extension bracket and the equipment to form a double shock-absorbing structure with the spring shock absorber.

[0017] Further, the threshold value set in step S1) is 150mm, and the set ratio is 70%.

[0018] Further, in step S2), the outer component is formed by welding two channel steels face to face to form a box-shaped cross-section structure. The interior of the outer component is a hollow structure. The two ends of the outer component are provided with openings. Several first bolt positioning holes are provided on the outer component. The several first bolt positioning holes are arranged on the outer component at intervals. The diameter of the first bolt positioning holes is φ12.

[0019] Furthermore, in step S4), the two inner components are inserted from both ends of the outer component and can slide along the axial direction of the outer component. The high-strength bolt passes through the first bolt positioning hole of the outer component and the second bolt positioning hole of the inner component to fix them in place.

[0020] Furthermore, a limiting steel plate is fixedly connected to the end of the inner layer component that is away from the interior of the outer layer component.

[0021] Furthermore, both inner side walls of the inner layer component are fixed with reinforcing steel plates, which extend along the length of the inner layer component and are completely fitted to the inner side walls of the inner layer component.

[0022] Furthermore, the device described in step S7) is fixed to the rubber shock-absorbing pad above the extension bracket by connecting bolts.

[0023] Furthermore, the outer component is a rectangular steel tube.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1) The construction method of this invention includes determining the core stress area of ​​the equipment foundation, fabricating outer components, fabricating inner components, assembling the outer and inner components into an extension bracket, adjusting the position of the equipment stress point, installing H-beam steel components, and fixing the equipment. This invention, by pre-determining the core stress area and using an extension bracket for fine-tuning, ensures that the equipment load is accurately transferred to the strongest area of ​​the equipment foundation through the bracket, avoiding stress concentration and protecting the equipment. The extension bracket, assembled from the outer component and two inner components, allows for flexible length adjustment, thereby precisely adjusting the position of the equipment stress point. It can adapt to various scenarios such as equipment foundation design deviations and equipment installation position deviations, ensuring that the stress point always falls within the core stress area of ​​the foundation and improving the flexibility of equipment installation.

[0026] 2) In this invention, a limiting steel plate is fixedly connected to the outside of the end of the inner layer component that is away from the inside of the outer layer component. When the length of the extension bracket is adjusted, the limiting steel plate can prevent the inner layer component from being excessively inserted into the outer layer component, thus ensuring the structural stability of the extension bracket.

[0044] The present invention will now be described in detail with reference to the accompanying drawings, which form part of this specification. The principles of the invention are illustrated by means of embodiments, and other aspects, features, and advantages of the invention will become apparent from this detailed description. In the accompanying drawings, the same or similar parts in different figures are indicated by the same reference numerals.

[0045] like Figures 1-16 As shown, the present invention provides a construction method in which the stress point 51 of the equipment falls on the core stress area 61 of the equipment foundation. The construction method includes the following steps:

[0046] Step S1) Determine the core load-bearing area 61 of the equipment foundation for the equipment 5 to be installed: Based on the length X and width Y of the equipment foundation 6, calculate the core load-bearing area of ​​the equipment 5 in the X direction of the equipment foundation 6 as 70%X to 85%X, and calculate the core load-bearing area of ​​the equipment 5 in the Y direction of the equipment foundation 6 as 70%Y to 85%Y. Consider the arrangement of the support points of the equipment 5 on the equipment foundation 6 and the optimal load-bearing position of the equipment foundation 6. Calculate the core load-bearing area of ​​the equipment 5 based on the dimensions of the equipment foundation 6. The core load-bearing area must meet the following principles:

[0047] Step S11) Symmetrical distribution: The support points of equipment 5 are symmetrically arranged along the center line of equipment foundation 6 to form a support surface, so that the load is evenly transferred to the overall structure of equipment foundation 6. The geometric center of the support surface should coincide with the center of gravity of equipment 5 on the vertical projection to avoid the eccentric load causing the equipment foundation 6 to tilt.

[0048] Step S12) Avoid the edge 62 and four corners of the equipment foundation: The distance between the edge of the support point of the equipment 5 and the side of the equipment foundation 6 is ≥150mm to prevent local stress concentration from causing cracks at the edge 62 of the equipment foundation 6. It is forbidden to place it directly at the four corners of the equipment foundation 6 because the four corner areas of the equipment foundation 6 have a higher risk of settlement and the concrete shrinkage stress is easy to concentrate there.

[0049] Step S3) Maximize the support area: The support surface formed by connecting the support points of equipment 5 should cover more than 70% of the bottom area of ​​equipment 5 to ensure load distribution. The distance between the support points of adjacent equipment 5 should not be too small to avoid local overload of the equipment foundation 6. The specific location of equipment 5 must meet the following requirements:

[0050] (1) X direction (length): between 70%X and 85%;

[0051] (2) Y direction (width): between 70%Y and 85%Y;

[0052] Step S2) Fabricate outer component 11: Based on the distance between the two force points of the device 5 in the Y direction, fabricate outer component 11 and reserve the first bolt positioning hole 111 on it;

[0053] Step S3) Fabricate inner layer component 12: Determine the length of inner layer component 12 based on the shortest distance from the stress point 51 of the equipment to the stress core area, and reserve a second bolt positioning hole 121 on inner layer component 12;

[0054] Step S4) Assemble the extension bracket 1: Insert the two inner layer components 12 into the outer layer components 11 from both ends, and connect and fix them with high-strength bolts 13, thereby assembling an adjustable length extension bracket 1.

[0055] Step S5) Adjust the position of the equipment stress point 51: Place the outer component 11 on the equipment foundation 6, loosen the high-strength bolt 13, adjust the depth of the two inner components 12 inserted into the outer component 11, so that the ends of the two inner components 12 away from the outer component 11 are accurately located in the stress core area of ​​the equipment foundation 6, and then fix the inner component 12 and the outer component 11 with the high-strength bolt 13; In specific implementation, by repeatedly fine-tuning the insertion length of the inner component 12 and checking its end position, it is ensured that it is accurately located in the stress core area of ​​the equipment foundation 6.

[0056] Step S6) Install H-beam steel component 3: Lay several spaced spring shock absorbers 2 above the equipment foundation 6, hoist the H-beam steel component 3 to the top of the spring shock absorbers 2, so that the web of the H-beam steel component 3 is perpendicular to the surface of the equipment foundation 6, and fix the assembled and adjusted extension bracket 1 above the H-beam steel component 3; so that the H-beam steel component 3 can be used to diffuse and transfer the load of the equipment 5; in specific implementation, use expansion bolts to fix the bottom of the spring shock absorber 2 to the equipment foundation 6, use bolts to fix the flange of the H-beam steel component 3 to the top of the spring shock absorber 2, and then hoist the adjusted length of the extension bracket 1 to the top of the H-beam steel component 3, so that the bottom of the extension bracket 1 is in contact with the upper flange of the H-beam steel component 3. This invention further diffuses the stress points 51 of the equipment by setting the H-beam steel component 3 and the spring shock absorber 2 between the bottom of the extension bracket 1 and the equipment foundation 6, so that the stress on the equipment foundation 6 is more uniform.

[0057] Step S7) Fixing Equipment 5: Fix Equipment 5 above the extension bracket 1, and lay rubber shock-absorbing pads 4 between the extension bracket 1 and Equipment 5 to form a double shock-absorbing structure with the spring shock absorbers 2. In specific implementation, several spring shock absorbers 2 are arranged at intervals between the H-shaped steel component 3 and the equipment foundation 6. The top of the spring shock absorber 2 is fixed to the bottom of the H-shaped steel component 3 by fixing bolts 31, and the bottom of the spring shock absorber 2 is fixed to the top of the equipment foundation 6. The spring shock absorber 2 can absorb the vibration load generated during the operation of Equipment 5 and reduce the impact of vibration on the equipment foundation 6.

[0058] The construction method of this invention pre-determines the core stress area and uses the extendable support 1 for fine-tuning to ensure that the load of the equipment 5 is accurately transferred to the strongest area of ​​the equipment foundation 6 through the extendable support 1, avoiding stress concentration and protecting the equipment 5. By manufacturing outer layer component 11 and inner layer component 12, and assembling the outer and inner layer components 12 into the extendable support 1, the length of the extendable support 1 is adjustable, which can flexibly adjust the position of the equipment stress point 51, ensuring that it accurately falls within the core stress area 61 of the equipment foundation 6. It can adapt to equipment 5 of different sizes and different installation position requirements, has strong versatility, avoids reconstruction and modification due to the equipment foundation 6 being incompatible with new equipment 5, significantly reduces costs, and shortens the construction period. This design improves construction efficiency and reliability. By fixing rubber damping pads 4 between the extension bracket 1 and the equipment 5, and installing spring dampers 2 between the adjusted stress point 51 of the equipment and the equipment foundation 6, a dual damping effect is achieved, effectively isolating vibration. This is particularly suitable for vibration-sensitive precision equipment 5. An H-shaped steel component 3 is installed below the extension bracket 1. The H-shaped steel component 3 helps to distribute the stress point, further evenly distributing the load on the equipment 5. Combined with the dual damping effect of the spring dampers 2 and the rubber damping pads 4, this effectively makes the stress on the equipment 5 more uniform, reducing the risk of cracking and failure of the equipment foundation 6, improving the stability and safety of the equipment 5 installation, and reducing safety hazards caused by uneven stress. The entire construction and installation process is simple, requiring only adjustment of the length of the extension bracket 1, fixing of various components, and laying of damping parts. No complex construction techniques are needed, making it suitable for various equipment 5 installation scenarios (such as machine tools, heavy-duty motors, conveying equipment 5, etc.).

[0059] In specific implementation, the threshold value set in step S1) is 150mm, and the set ratio is 70%.

[0060] In step S2), the present invention uses two channel steels welded face to face to form an outer layer component 11 with a box-shaped cross-section structure. The interior of the outer layer component 11 is a hollow structure. The two ends of the outer layer component 11 are provided with openings. A plurality of first bolt positioning holes 111 are provided on the outer layer component 11. The plurality of first bolt positioning holes 111 are arranged on the outer layer component 11 at intervals. The diameter of the first bolt positioning holes 111 is φ12. The outer layer component 11 is a rectangular steel pipe.

[0061] In step S4), two inner layer components 12 are inserted from both ends of the outer layer component 11 and can slide along the axial direction of the outer layer component 11. High-strength bolts 13 pass through the first bolt positioning hole 111 of the outer layer component 11 and the second bolt positioning hole 121 of the inner layer component 12 to fix them in place. The outer layer component 11 and inner layer component 12 manufactured in this invention are fixed in place by high-strength bolts 13 to form an extension bracket 1, allowing the inner layer component 12 to slide within the outer layer component 11. The second bolt positioning hole 121 on the inner layer component 12 corresponds to the first bolt positioning holes 111 at different positions on the outer layer component 11, enabling the extension and adjustment of the extension bracket 1 to different lengths. Specifically, in this invention, a limiting steel plate 122 is fixedly connected to the external end of the inner layer component 12 away from the interior of the outer layer component 11. When the extension bracket 1 is adjusted in length, the limiting steel plate 122 can prevent the inner layer component 12 from being excessively inserted into the outer layer component 11, ensuring the structural stability of the extension bracket 1. Reinforcing steel plates 123 are fixed on both inner side walls of the inner layer component 12. The reinforcing steel plates 123 extend along the length direction of the inner layer component 12 and are completely attached to the inner side wall of the inner layer component 12. The main purpose of fixing the reinforcing steel plates 123 in the inner layer component 12 is to improve the bending strength of the inner layer component 12 and prevent the inner layer component 12 from deforming when bearing the load of the equipment 5.

[0062] In specific implementation, the device 5 described in step S7) is fixed to the rubber shock-absorbing pad 4 above the extension bracket 1 by connecting bolts 52. In this invention, the rubber shock-absorbing pad 4 is laid on top of the extension bracket 1. The material of the rubber shock-absorbing pad 4 can be nitrile rubber, which has good shock absorption and wear resistance. The rubber shock-absorbing pad 4 is tightly fitted to the top of the extension bracket 1 and the bottom of the device 5. The device 5 is fixed to the rubber shock-absorbing pad 4 by connecting bolts 52. The rubber shock-absorbing pad 4 can further buffer the vibration of the device 5, while avoiding rigid collisions between the device 5 and the extension bracket 1, protecting the bottom structure of the device 5. This invention utilizes the length adjustment of the extension bracket 1 in conjunction with the double shock-absorbing structure to improve the stability of the device 5 installation, avoid problems such as increased vibration and component wear caused by uneven force, and reduce safety hazards.

[0063] To make the technical solution of the present invention clearer and easier to understand, the present invention will be further described in detail below with reference to specific embodiments.

[0064] This embodiment takes a cuboid equipment foundation 6 with four support points for equipment 5 as an example. The length of the equipment foundation 6 is X=2000mm and the width is Y=1500mm. Equipment 5 needs to be installed on the equipment foundation 6. The distance between the stress points of equipment 5 in the Y direction is Y1=800mm. The bottom area of ​​equipment 5 is approximately 3m². The initial position of the support points of equipment 5 may deviate from the core stress area. The specific construction process of installing equipment 5 using the construction method of this invention is as follows:

[0065] Step S1) Determine the core load-bearing area 61 of the equipment foundation: First, calculate the core load-bearing area based on the dimensions of the equipment foundation 6 (X=2000mm, Y=1500mm). The core area must meet the following principles:

[0066] Symmetrical distribution: The support points of equipment 5 are symmetrically arranged along the centerline of equipment foundation 6 to form a rectangular support surface. The geometric center of the support surface coincides with the center of gravity of equipment 5 in the vertical projection. The dimensions of the support surface are calculated as follows:

[0067] The range of the pivot point position in the X direction is between 70%×2000=1400mm and 85%×2000=1700mm.

[0068] The range of the fulcrum position in the Y direction is between 70%×1500=1050mm and 85%×1500=1275mm.

[0069] Avoid edges and corners: the distance between the edge of the fulcrum and the side of the equipment foundation 6 is ≥150mm, and it is prohibited to place it in the corner area; in Embodiment 1 of the present invention, the minimum distance between the fulcrum of the equipment 5 and the edge of the equipment foundation 6 is set to 200mm.

[0070] Maximizing the support area: The rectangular support surface formed by connecting the fulcrums covers more than 70% of the bottom area of ​​equipment 5. The calculated support surface area is at least 3m² × 70% = 2.1m². If the initial position of the fulcrum of equipment 5 is not within the above range, it can be adjusted by extending the bracket 1.

[0071] Step S2) Fabrication of outer component 11: Select two channel steels and weld them face to face to form an outer component 11 with a box-shaped cross section. The length L1 of the outer component 11 is calculated according to the following formula L1=Y1+600mm, where Y1 is the distance between the force points of the equipment 5 in the Y direction. In Embodiment 1 of the present invention, the distance between the force points of the equipment 5 in the Y direction is Y1=800mm, so the length L1=Y1+600mm=1600mm of the outer component 11 is obtained. Several first bolt positioning holes 111 are reserved along the length direction on the outer component 11. The hole diameter is φ12mm and the hole spacing is set according to the adjustment requirements. In Embodiment 1 of the present invention, there is one first bolt positioning hole 111 every 100mm, which is used for subsequent connection with the inner component 12.

[0072] Step S3) Fabrication of inner layer component 12: The inner layer component 12 is made of the same channel steel material. The length L2 of the inner layer component 12 is determined according to the actual extension requirements. In this embodiment 1, L2=800mm. The inner layer component 12 is processed according to this length. A second bolt positioning hole 121 with a diameter of φ12mm is also reserved on the inner layer component 12. The hole spacing matches the first bolt positioning hole 111 of the outer layer component 11 to ensure alignment during sliding.

[0073] Step S4) Assemble the extension bracket 1: Insert the two prepared inner layer components 12 into the outer layer component 11 and fix them in place with high-strength bolts 13 to form the extension bracket 1. In this embodiment 1, the high-strength bolts 13 are preferably 8.8 grade M12 bolts. By sliding the inner layer component 12, the second bolt positioning hole 121 on the inner layer component 12 corresponds to the first bolt positioning hole 111 at different positions on the outer layer component 11. The length of the extension bracket 1 can be continuously adjusted within the range of 1200mm to 2000mm. In order to strengthen the connection strength, a total of 4 high-strength bolts 13 are set for fixation.

[0074] Step S5) Adjust the position of the equipment stress point 51: Place the outer component 11 on the equipment foundation 6, ensuring that the support point of the equipment 5 is completely seated on the outer component 11. Adjust the length of the inner component 12 extending into the outer component 11 so that the ends of the two inner components 12 are seated within the core stress area 61 of the equipment foundation determined in step S1) (i.e., within the range of 1400-1700mm in the X direction and 1050-1275mm in the Y direction). Securely fix the inner component 12 and the outer component 11 with high-strength bolts 13. In this embodiment, the support point of the equipment 5 can be adjusted from the initial non-core area (e.g., 1200mm in the X direction and 900mm in the Y direction) to the core area by extending the bracket 1, so that the load is evenly distributed.

[0075] Step S6) Install H-beam steel component 3: Lay several spaced spring dampers 2 above the equipment foundation 6, hoist the H-beam steel component 3 to the top of the spring dampers 2, so that the web of the H-beam steel component 3 is perpendicular to the surface of the equipment foundation 6, and fix the assembled and adjusted extension bracket 1 above the H-beam steel component 3. The length L3 of the H-beam steel is adjusted according to the actual diffusion requirements. In this embodiment 1, the length L3 of the H-beam steel is 1600mm and the height is 200mm. The H-beam steel component 3 is arranged along the length of the equipment foundation 6 to convert the point load into a line load and reduce the local stress of the equipment foundation 6.

[0076] Step S7) Fixing the device 5: Finally, place the device 5 on top of the extension bracket 1, fix the device 5 on top of the extension bracket 1, and lay a rubber shock-absorbing pad 4 between the extension bracket 1 and the device 5 to ensure the stability of the device 5, thus completing the fixed installation of the device 5.

[0077] As can be seen from the above embodiment 1, the construction method of the present invention can effectively adjust the position of the equipment stress point 51, ensure that the equipment foundation 6 is subjected to uniform stress, and is simple to operate and has low cost, which can well meet the installation requirements of the equipment 5.

[0078] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of this application. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
