Description

Technical Field

[0001] This application relates to the field of construction technology in the oil and gas storage and transportation industry, and in particular to a dry connection device and a dry connection method. Background Technology

[0002] In the oil and gas storage and transportation industry, most concrete structures currently employ cast-in-place technology, requiring on-site reinforcement binding and formwork erection before concrete pouring. This approach suffers from drawbacks such as long design cycles and construction periods, leading to slow project progress. Furthermore, the complex on-site environment and significant susceptibility to external weather conditions make it difficult to guarantee construction quality. Summary of the Invention

[0003] In view of this, this application provides a dry connection device and a dry connection method, which can reduce on-site construction work and improve construction speed and quality.

[0004] Specifically, the following technical solutions are included:

[0005] In a first aspect, embodiments of this application provide a dry connection device, which includes a first mounting plate, a second mounting plate, a force-transmitting reinforcing bar, and a sleeve. The first mounting plate and the second mounting plate are connected perpendicularly to each other. The force-transmitting reinforcing bar is disposed on the first mounting plate. The sleeve has a hollow structure and is disposed on one side of the second mounting plate. The force-transmitting reinforcing bar is used to be embedded in a precast component, and the sleeve is used to connect with the foundation.

[0006] In this embodiment, by setting force-transmitting steel bars, the dry connection device can be pre-connected to the precast components, reducing on-site construction work and not affecting other construction procedures. During on-site construction, the connection between the precast components and the foundation can be achieved simply by connecting the hollow structure sleeve to the foundation. The demand for human resources and the amount of high-altitude work are relatively reduced throughout the construction process, effectively reducing operational risks, shortening the construction period, and helping to reduce environmental pollution. It also solves the problem that precast concrete components in common oil and gas storage and transportation structures cannot achieve dry connection, and the connection performance of the dry connection device can be equivalent to that of cast-in-place construction.

[0007] In an optional embodiment, the force-transmitting reinforcing bars are multiple.

[0008] By setting multiple reinforcing bars, the structural stability and load transfer effect of the dry connection device can be enhanced, and the load-bearing capacity of the precast components can be improved.

[0009] In an optional embodiment, the dry connection device further includes ribs perpendicular to the first mounting plate and the second mounting plate, respectively.

[0010] By setting ribs, the stability and strength of the dry connection device structure can be enhanced, preventing the first and second mounting plates from shaking. When subjected to external forces, the ribs can disperse stress, preventing the dry connection device from deforming or being damaged, effectively improving the overall rigidity of the dry connection device and optimizing its dynamic characteristics.

[0011] In an optional embodiment, the sleeve is connected to the rib.

[0012] This configuration helps improve the structural stability of the dry connection device, allowing the load of the precast components to be transferred to the foundation in sequence through the ribs and sleeves, thereby effectively transferring and distributing the load.

[0013] In an optional embodiment, the force-transmitting reinforcing bar is located at the connection between the rib and the first mounting plate, and the force-transmitting reinforcing bar is connected to both the rib and the first mounting plate.

[0014] This design improves the stability of the reinforcing bars, preventing them from bending or tipping over, and ensuring that they effectively transfer and distribute the load.

[0015] In an optional embodiment, there are two force-transmitting reinforcing bars, which are located on both sides of the rib plate in the thickness direction.

[0016] In this embodiment, the two reinforcing bars can more fully transfer the load of the precast components, which helps to improve the stability of the dry connection device.

[0017] In an optional embodiment, the dry connection device further includes a threaded element and a nut, the threaded element being embedded in the foundation and capable of passing through the sleeve, and the nut being threadedly connected to the threaded element to lock the threaded element and the sleeve.

[0018] In this embodiment, before on-site construction, the dry connection device is pre-embedded in the precast component and the threaded part is pre-embedded in the foundation. During on-site construction, the sleeve is simply passed through the threaded part, the nut is threadedly connected to the threaded part and tightened, and the gap is filled with grout to achieve the connection between the precast component and the foundation. This greatly improves the construction speed and shortens the construction period by at least 30% compared to cast-in-place technology, achieving improved quality and efficiency, energy conservation and emission reduction.

[0019] In an optional embodiment, the first mounting plate, the second mounting plate, and the sleeve are all metal parts, and the force-transmitting steel bar is welded to the first mounting plate.

[0020] In this embodiment, the first mounting plate, the second mounting plate, and the sleeve all have high mechanical strength, good heat resistance, durability, and strong dimensional stability; the force transmission steel bars are welded to the first mounting plate, which has the advantages of high structural strength and low cost.

[0021] Secondly, embodiments of this application provide a dry connection method, wherein the dry connection method employs the dry connection device provided in any embodiment of the first aspect, and the dry connection method includes:

[0022] The force-transmitting steel bars in the dry connection device are pre-embedded in the prefabricated components;

[0023] Connect the sleeve in the dry connection device to the foundation;

[0024] Grouting material is used to fill the gaps between the dry connection device, the precast component, and the foundation.

[0025] In an optional embodiment, the dry connection device further includes a threaded component and a nut, the threaded component being embedded in the foundation and capable of passing through the sleeve, and the nut being threadedly connected to the threaded component to lock the threaded component and the sleeve.

[0026] The process of connecting the sleeve in the dry connection device to the foundation specifically includes:

[0027] The sleeve is fitted onto the outside of the threaded component, and the nut is tightened to achieve a mating connection between the sleeve and the foundation.

[0028] The beneficial effects of the technical solution provided in this application embodiment include at least the following: by setting force-transfer reinforcing bars, the dry connection device can be pre-connected to the precast components, reducing on-site construction work and not affecting other construction procedures; during on-site construction, the connection between the precast components and the foundation can be achieved simply by connecting the hollow structure sleeve to the foundation, which reduces the demand for human resources and the amount of high-altitude work during the entire construction process, effectively reducing operational risks, shortening the construction period, helping to reduce environmental pollution, and solving the problem that precast concrete components in common oil and gas storage and transportation structures cannot achieve dry connection, and the connection performance of the dry connection device can be equivalent to that of cast-in-place.

[0046] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0047] In the oil and gas storage and transportation industry, most concrete structures currently employ cast-in-place technology, requiring on-site reinforcement binding and formwork erection before concrete pouring. This presents the following problems:

[0048] (1) The design cycle and construction period are long, resulting in slow progress of project investment;

[0049] (2) The construction site environment is complex, and the construction quality is not easy to guarantee;

[0050] (3) Traditional construction methods are greatly affected by external climate, especially during winter construction;

[0051] (4) The construction process is prone to environmental pollution and does not meet the requirements of green and low-carbon development.

[0052] To address the aforementioned issues, this application provides a dry connection device 1 and a dry connection method.

[0053] like Figures 1 to 3As shown, the dry connection device 1 provided in this embodiment includes a first mounting plate 11, a second mounting plate 12, a force-transmitting steel bar 13, and a sleeve 14. The first mounting plate 11 and the second mounting plate 12 are connected perpendicularly to each other. The force-transmitting steel bar 13 is disposed on the first mounting plate 11, and the sleeve 14 is a hollow structure disposed on one side of the second mounting plate 12. The force-transmitting steel bar 13 is used for pre-embedding in the precast component 2, and the sleeve 14 is used for connection with the foundation. Exemplarily, the dry connection device 1 is applied in municipal, transportation, water conservancy, and oil and gas storage and transportation fields.

[0054] like Figure 2 As shown, the first mounting plate 11 and the second mounting plate 12 are connected perpendicularly to each other in an "L" shape.

[0055] Specifically, the force-transmitting steel bar 13 is used to transmit loads. The length of the force-transmitting steel bar 13 is greater than the height of the first mounting plate 11, and the force-transmitting steel bar 13 protrudes outward relative to the top of the first mounting plate 11.

[0056] The bottom end of the force-transferring steel bar 13 can abut against the second mounting plate 12, or the bottom end of the force-transferring steel bar 13 can be spaced apart from the second mounting plate 12, for example... Figure 1 As shown, the bottom end of the force transmission steel bar 13 does not contact the second mounting plate 12, that is, the bottom end of the force transmission steel bar 13 and the second mounting plate 12 are spaced apart from each other.

[0057] Understandably, the top of the first mounting plate 11 is... Figure 1 The upper end of the first mounting plate 11 shown, and the bottom end of the force-transmitting steel bar 13 are... Figure 1 The lower end of the force-transmitting steel bar 13 shown.

[0058] Precast component 2 is a concrete component such as precast columns and precast walls. Precast component 2 can be prefabricated in the factory, reducing on-site construction time. It has good structural performance, can effectively guarantee the mechanical properties of the structure, has low dispersion, good product quality, and high surface smoothness. In addition, precast component 2 also has the advantages of saving labor, overcoming seasonal influences, and facilitating year-round construction.

[0059] After the dry connection device 1 is fabricated and assembled, the force-transferring steel bars 13 are pre-embedded in the precast component 2 to achieve the connection between the dry connection device 1 and the precast component 2. This eliminates the need for on-site casting of the precast component 2, effectively reducing the time spent on on-site construction. Multiple force-transferring steel bars 13 of the dry connection device 1 can be pre-embedded in the same precast component 2, thereby improving the connection stability between the precast component 2 and the foundation.

[0060] In the existing technology, precast component 2 usually needs to be processed and precast in an upright position. During the concrete pouring process, materials such as gravel and sand are prone to sinking in the vertical direction, resulting in uneven distribution, insufficient compaction, and easy formation of honeycomb surface, which affects the quality of precast component 2.

[0061] The dry connection device 1 provided in this application embodiment allows the precast component 2 to be processed in a horizontal or inclined position during the process of pre-embedding the force transmission steel bar 13 in the precast component 2, which avoids the concrete material from sinking, helps to improve the compaction of the concrete and reduce honeycomb surface defects.

[0062] like Figure 1 As shown, the sleeve 14 is positioned opposite to the first mounting plate 11. The sleeve 14 is cylindrical and hollow inside, making it easy to fit into the protruding structure of the foundation to achieve initial positioning between the dry connection device 1 and the foundation. For example, the protruding structure of the foundation can be a bolt, thread, steel bar, or other similar structure.

[0063] For example, after the precast component 2 is connected to the foundation through the sleeve 14, grouting material is used to fill the gap between the dry connection device 1, the precast component 2 and the foundation, to strengthen the connection strength and mechanical properties of the foundation, the precast component 2 and the dry connection device 1, prevent the metal materials from rusting, and help improve the load-bearing capacity, shock resistance, corrosion resistance and durability.

[0064] The dry connection device 1 provided in this application embodiment can be pre-connected to the precast component 2 by setting the force transmission steel bar 13, which reduces on-site construction work and does not affect other construction procedures. During on-site construction, the connection between the precast component 2 and the foundation can be achieved simply by connecting the hollow sleeve 14 to the foundation. The demand for human resources and the amount of high-altitude work are relatively reduced during the entire construction process, which effectively reduces the operation risk, shortens the construction period, helps to reduce environmental pollution, and solves the problem that precast concrete components of common oil and gas storage and transportation structures cannot achieve dry connection. Moreover, the connection performance of the dry connection device 1 can be equivalent to that of cast-in-place.

[0065] In a further embodiment, there are multiple force-transmitting reinforcing bars 13. Depending on actual needs, the multiple force-transmitting reinforcing bars 13 can be distributed at intervals or connected to each other, and the size and spacing of the force-transmitting reinforcing bars 13 can also be set according to actual conditions.

[0066] By setting multiple reinforcing bars 13, the structural stability and load transfer effect of the dry connection device 1 can be enhanced, and the bearing capacity of the precast component 2 can be improved.

[0067] In one embodiment, the dry connection device 1 further includes a rib plate 15, which is perpendicular to the first mounting plate 11 and the second mounting plate 12, respectively.

[0068] like Figure 3 As shown, the horizontal direction is the length direction of the first mounting plate 11, and the rib plate 15 is connected at the midpoint of the length direction of the first mounting plate 11 and is perpendicular to the extension plane of the second mounting plate 12.

[0069] Specifically, the rib plate 15 is a metal part, and the rib plate 15 is connected to the first mounting plate 11 and the second mounting plate 12 by welding, which has the advantages of high structural strength and low cost.

[0070] Optionally, the rib 15 may be one or more, for example Figures 1 to 3 As shown, there is one rib plate 15.

[0071] By setting the rib plate 15, the stability and strength of the dry connection device 1 structure can be enhanced, and the first mounting plate 11 and the second mounting plate 12 can be prevented from shaking. When subjected to external force, the rib plate 15 can disperse the stress, avoid deformation or damage of the dry connection device 1, effectively improve the overall rigidity of the dry connection device 1, and optimize the dynamic characteristics of the dry connection device 1.

[0072] Furthermore, sleeve 14 is connected to rib 15. For example... Figure 3 As shown, one end of the rib plate 15 is connected to the first mounting plate 11, and the other end is connected to the outer wall of the sleeve 14.

[0073] For example, the rib 15 and the sleeve 14 are connected by welding. Optionally, the length of the connection between the rib 15 and the sleeve 14 is more than 50% of the height of the sleeve 14, thereby ensuring high connection strength and load transfer effect between the rib 15 and the sleeve 14, which helps to improve the structural stability of the dry connection device 1. It is understood that the height of the sleeve 14 is... Figure 2 The linear dimension of sleeve 14 in the vertical direction.

[0074] The steel bars and load-bearing steel bars 13 inside the precast component 2 transfer the load through the bond force of the concrete. Since the sleeve 14 is connected to the rib plate 15, the load of the precast component 2 can be further transferred to the foundation through the rib plate 15 and the sleeve 14 in sequence, thereby effectively transferring and distributing the load.

[0075] In one embodiment, the force-transmitting steel bar 13 is located at the connection between the rib plate 15 and the first mounting plate 11, and the force-transmitting steel bar 13 is connected to the rib plate 15 and the first mounting plate 11 respectively.

[0076] like Figure 3As shown, the force-transmitting steel bar 13 is clamped between the rib plate 15 and the first mounting plate 11. One side of the force-transmitting steel bar 13 is connected to the rib plate 15, and the other side is connected to the first mounting plate 11.

[0077] This design improves the stability of the load-bearing steel bar 13, preventing it from bending or tipping over, and ensuring that the load-bearing steel bar 13 effectively transmits and distributes the load.

[0078] Specifically, there are two force-transmitting steel bars 13, which are located on both sides of the thickness direction of the rib plate 15.

[0079] like Figure 3 As shown, the horizontal direction is the thickness direction of the rib plate 15, and the two force transmission steel bars 13 are located on the left and right sides of the rib plate 15 respectively, and both force transmission steel bars 13 are clamped between the rib plate 15 and the first mounting plate 11.

[0080] In this embodiment, the two reinforcing bars 13 can more fully transmit the load of the precast component 2, which helps to improve the stability of the dry connection device 1.

[0081] In one embodiment, the dry connection device 1 further includes a threaded member 16 and a nut 17. The threaded member 16 is embedded in the foundation and can pass through the sleeve 14. The nut 17 is used to thread the threaded member 16, thereby locking the threaded member 16 and the sleeve 14.

[0082] Specifically, the threaded part 16 is a fastener with external threads, such as a bolt or screw. Part of the threaded part 16 is embedded in the foundation, and the other part protrudes outward relative to the foundation.

[0083] The radial dimension of the nut 17 is greater than or equal to the inner diameter of the sleeve 14, so that the nut 17 can limit the sleeve 14 in the height direction.

[0084] For example, before on-site construction, the dry connection device 1 is pre-embedded in the precast component 2 and the threaded part 16 is pre-embedded in the foundation. During on-site construction, the sleeve 14 is simply passed through the threaded part 16, and the nut 17 is threadedly connected to the threaded part 16 and tightened. Then, the gap is filled with grout, which can realize the connection between the precast component 2 and the foundation. This greatly improves the construction speed and can shorten the construction period by at least 30% compared with the cast-in-place technology, thus achieving quality improvement, efficiency enhancement, energy saving and emission reduction.

[0085] In one specific embodiment, the first mounting plate 11, the second mounting plate 12, and the sleeve 14 are all metal parts, possessing high mechanical strength, good heat resistance, durability, and strong dimensional stability. The force-transmitting steel bar 13 is welded to the first mounting plate 11, offering advantages such as high structural strength and low cost.

[0086] For example, both the first mounting plate 11 and the second mounting plate 12 are made of carbon structural steel, which is not only easy to process, but also has a strong load-bearing capacity.

[0087] Specifically, the first mounting plate 11 and the second mounting plate 12 are fixedly connected by welding to ensure the stability and reliability of the connection between the first mounting plate 11 and the second mounting plate 12.

[0088] Optionally, such as Figure 4 and Figure 5 As shown, this application embodiment also provides a prefabricated component, which includes a prefabricated member 2 and a dry connection device 1 provided in any of the above embodiments, wherein the force-transmitting steel bar 13 of the dry connection device 1 is embedded in the prefabricated member 2.

[0089] Precast component 2 is a precast column, precast wall, or other concrete component, for example... Figure 4 or Figure 5 As shown, prefabricated component 2 is a square column.

[0090] Precast component 2 can be prefabricated in the factory, reducing on-site construction time. It has good structural performance, effectively ensuring structural mechanical properties, low dispersion, good product quality, and high surface smoothness. In addition, precast component 2 also has the advantages of saving labor, overcoming seasonal influences, and facilitating year-round construction.

[0091] After the dry connection device 1 is manufactured and assembled, the force transmission steel bar 13 is embedded in the precast component 2 to realize the connection between the dry connection device 1 and the precast component 2, so that the precast component 2 does not need to be cast on site, effectively reducing the time occupied by on-site construction.

[0092] In this design, multiple reinforcing steel bars 13 of dry connection devices 1 can be pre-embedded in the same precast component 2, thereby improving the connection stability between the precast component 2 and the foundation. For example... Figure 5 As shown, eight dry connection devices 1 are provided at the bottom of the prefabricated component 2.

[0093] The prefabricated components provided in this application embodiment can connect the dry connection device 1 to the prefabricated component 2 in advance, reducing on-site construction work and not affecting other construction procedures. During on-site construction, the connection between the prefabricated component 2 and the foundation can be achieved simply by connecting the hollow sleeve 14 to the foundation. The demand for human resources and the amount of high-altitude work are relatively reduced throughout the construction process, effectively reducing operational risks and shortening the construction period. It also solves the problem that prefabricated concrete components 2 in common oil and gas storage and transportation structures cannot achieve dry connection, and the connection performance of the dry connection device 1 can be equivalent to that of cast-in-place.

[0094] In an optional embodiment, there are multiple force-transmitting reinforcing bars 13.

[0095] In an optional embodiment, the dry connection device 1 further includes a rib 15, which is perpendicular to the first mounting plate 11 and the second mounting plate 12, respectively.

[0096] In an alternative embodiment, sleeve 14 is connected to rib 15.

[0097] In an optional embodiment, the force-transmitting steel bar 13 is located at the connection between the rib plate 15 and the first mounting plate 11, and the force-transmitting steel bar 13 is connected to the rib plate 15 and the first mounting plate 11 respectively.

[0098] In an optional embodiment, there are two force-transmitting reinforcing bars 13, which are located on both sides of the rib plate 15 in the thickness direction.

[0099] In an optional embodiment, the dry connection device 1 further includes a threaded member 16 and a nut 17, the threaded member 16 being embedded in the foundation and capable of passing through the sleeve 14, and the nut 17 being threadedly connected to the threaded member 16, thereby locking the threaded member 16 and the sleeve 14.

[0100] In an optional embodiment, the first mounting plate 11, the second mounting plate 12, and the sleeve 14 are all metal parts, and the force transmission steel bar 13 is welded to the first mounting plate 11.

[0101] This application also provides a dry connection method, which employs the dry connection device 1 provided in any of the above embodiments, such as... Figure 6 As shown, the dry connection method includes:

[0102] S1: The force-transmitting steel bar 13 in the dry connection device 1 is pre-embedded in the precast component 2;

[0103] S2: Connect the sleeve 14 in the dry connection device 1 to the foundation;

[0104] S3: Use grouting material to fill the gap between the dry connection device 1, the precast component 2 and the foundation.

[0105] The dry connection method provided in this application embodiment pre-embeds the force-transmitting steel bar 13 in the precast component 2 in the dry connection device 1, reducing on-site construction work and not affecting other construction procedures. During on-site construction, the connection between the precast component 2 and the foundation can be achieved simply by connecting the hollow sleeve 14 to the foundation. The demand for human resources and the amount of high-altitude work are relatively reduced throughout the construction process, effectively reducing operational risks and shortening the construction period. It also solves the problem that precast concrete components 2 in common oil and gas storage and transportation structures cannot achieve dry connection, and the connection performance of the dry connection device 1 can be equivalent to that of cast-in-place construction. By filling the gaps with grout, the connection strength and mechanical properties of the foundation, precast component 2 and dry connection device 1 are strengthened, preventing metal materials from rusting and helping to improve load-bearing capacity, seismic resistance, corrosion resistance and durability.

[0106] Furthermore, the dry connection device 1 also includes a threaded component 16 and a nut 17. The threaded component 16 is embedded in the foundation and can pass through the sleeve 14. The nut 17 is used to thread the threaded component 16, thereby locking the threaded component 16 and the sleeve 14. Step S2, connecting the sleeve 14 of the dry connection device 1 to the foundation, specifically includes:

[0107] The sleeve 14 is fitted onto the outside of the threaded part 16, and the nut 17 is tightened to achieve a mating connection between the sleeve 14 and the foundation.

[0108] Specifically, the threaded part 16 is a fastener with external threads, such as a bolt or screw. Part of the threaded part 16 is embedded in the foundation, and the other part protrudes outward relative to the foundation.

[0109] The radial dimension of the nut 17 is greater than or equal to the inner diameter of the sleeve 14, so that the nut 17 can limit the sleeve 14 in the height direction.

[0110] For example, before on-site construction, the dry connection device 1 is pre-embedded in the precast component 2 and the threaded part 16 is pre-embedded in the foundation. During on-site construction, the sleeve 14 is simply passed through the threaded part 16, and the nut 17 is threadedly connected to the threaded part 16 and tightened. Then, the gap is filled with grout, which can realize the connection between the precast component 2 and the foundation. This greatly improves the construction speed and can shorten the construction period by at least 30% compared with the cast-in-place technology, thus achieving quality improvement, efficiency enhancement, energy saving and emission reduction.
