Description

Technical Field

[0001] This application relates to the field of cast-in-place bridge support technology, and more specifically, to an assembly device and a method for determining the parameters of the assembly device. Background Technology

[0002] When constructing a bridge using the cast-in-place bracket method, the corbel support at the bottom of the bracket is first embedded in the pier body as a pre-embedded part. Then, the bracket is obtained by welding the corbel support and the pier body. Casting is then carried out on this basis to realize the bridge construction.

[0003] Current technology typically involves pre-embedding anchor bars in the pier body, with one end of the anchor bar protruding from the outer wall of the pier body. The anchor bar is then anchored to the corbel to form a corbel support. The corbel support is then used as a support, and a bracket is fabricated on-site using I-beams welded together.

[0004] However, during construction, this type of corbel support is prone to issues such as incomplete concrete filling around the anchor holes, affecting the integrity of the original structural design. Furthermore, its load-bearing capacity is relatively low. For cast-in-place construction brackets in large cantilever structures with high load-bearing requirements, existing corbel supports cannot guarantee construction safety. In addition, this on-site welding method for obtaining the bracket requires a certain processing time, and after use, it can only be directly cut, with no space for reuse, thus resulting in material waste. Summary of the Invention

Simultaneously, the front end plate, the two side plates, and the rear end plate of the embedded part are sequentially and fixedly connected, forming a stable structure together with the base plate. Furthermore, filling the gaps in the embedded part during embedding ensures stable support of the bearing portion for the original structural integrity. Based on this, the shear plates, bearing plates, and rear end plates are vertically and fixedly connected, distributing the stress on the bearing plate evenly to the embedded part of the corbel support through the shear plates. This not only provides stable support for the prefabricated bracket but also ensures the load-bearing performance of the corbel support.

[0064] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It should be understood that the accompanying drawings in this application are for illustrative and descriptive purposes only and are not intended to limit the scope of protection of this application. Furthermore, it should be understood that the schematic drawings are not drawn to scale. The flowcharts used in this application illustrate operations implemented according to some embodiments of this application. It should be understood that the operations in the flowcharts may not be implemented in sequence, and steps without logical contextual relationships may be reversed or implemented simultaneously. In addition, those skilled in the art, guided by the content of this application, may add one or more other operations to the flowcharts, or remove one or more operations from the flowcharts.

[0065] Furthermore, the described embodiments are merely some, not all, of the embodiments of this application. The components of the embodiments of this application described and illustrated herein can typically be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0066] It should be noted that the term "comprising" will be used in the embodiments of this application to indicate the presence of the features declared thereafter, but does not exclude the addition of other features.

[0067] In existing bridge construction using the cast-in-place bracket method, anchor bars are typically pre-embedded in the pier body, with one end of the anchor bar protruding from the outer wall of the pier body. The anchor bar is then anchored to the corbel to form a corbel support. However, during construction, this type of corbel support is prone to issues where the concrete around the anchor bar holes is not fully filled, affecting the integrity of the original structural design.

[0068] As another possible approach, the existing cast-in-place bracket method for bridge construction involves pre-embedding a steel plate in the pier body. One side of the steel plate is welded to the reinforcing steel of the pier body, while the other side is exposed on the pier wall and welded to the corbel. However, this type of corbel support requires high-altitude welding during subsequent use, which is difficult to construct and makes it hard to guarantee the welding quality.

[0069] In addition, in the existing bridge cast-in-place bracket construction method, the bracket is used as a support based on the corbel bearing, and the bracket is fabricated on-site using I-beams welded together. When the construction is completed, the bracket and bearing are cut and dismantled.

[0070] However, when the aforementioned two types of bracket bases have high load-bearing requirements, such as supporting the load of cast-in-place construction brackets for large cantilever structures, they cannot guarantee the construction safety of the construction brackets. Furthermore, this method of welding brackets on-site requires a certain processing time, and after use, they can only be cut directly without any space for reuse, resulting in material waste.

[0071] Based on the aforementioned problems, this application proposes an assembly device that divides the corbel support into an embedded part and a pressure-bearing part. The embedded part and the pressure-bearing part are connected by multiple shear plates. A front end plate, a rear end plate, side plates, and a pressure-bearing plate are used to fix the shear plates, improving the stability of the corbel support. Based on this, a prefabricated bracket is installed for bridge cast-in-place bracket construction. Furthermore, a parameter determination method for the assembly device is proposed, analyzing the stress conditions of the assembly device to determine the material information of the prefabricated bracket.

[0072] First, the scenarios involved in the embodiments of this application will be described. Figure 1 This is an exemplary scenario diagram of the assembly device provided in an embodiment of this application, with reference to... Figure 1 As shown, this scenario may involve an assembly device and a structure. The structure may include bridge pier bodies and bridge cap beams. It should be understood that when constructing a bridge using the cast-in-place bracket method, the assembly device provided in this embodiment remains fixed to the bridge pier bodies of the structure, allowing the bridge cap beams to be cast in place using the assembly device provided in this embodiment, thus completing the construction.

[0073] The assembly apparatus provided in this application will be described in detail below with reference to several embodiments.

[0074] Figure 2 This is a schematic diagram of an overall structure of the assembly device provided in an embodiment of this application, with reference to... Figure 2 As shown, the assembly device 200 includes: an assembly bracket 400 and a bracket support 300.

[0075] It should be understood that the assembly device consists of two parts: a prefabricated bracket and a corbel support. The corbel support serves as a support during the construction and assembly process, providing stable support. The prefabricated bracket is fixed on the corbel support to enable the bridge to be cast in place.

[0076] Figure 3 This is a schematic diagram of the bracket support in the assembly device provided in the embodiments of this application, with reference to... Figure 3 As shown, the corbel support 300 includes: an embedded part 301 and a pressure-bearing part 302.

[0077] It should be understood that, in order to ensure the load-bearing performance of the corbel support, the corbel support is divided into a pre-embedded part that is embedded in the structure and a bearing part that is used to contact the prefabricated bracket. This allows the load on the prefabricated bracket in the assembly device to be distributed to the pre-embedded part of the corbel support through the bearing part of the corbel support. At the same time, since the pre-embedded part is set in the structure in advance, it can ensure construction safety while ensuring the integrity of the original structure.

[0078] The embedded part 301 includes a base plate 301a, a front end plate 301b, a rear end plate 301c, and two side plates 301d. The embedded part 301 is embedded in the structure during the casting process.

[0079] The front end plate 301b and the rear end plate 301c are arranged opposite each other and are both fixedly connected to the base plate 301a. The two side plates 301d are arranged opposite each other and the bottom of the side plates 301d is fixedly connected to the base plate 301a. The two sides of each side plate 301d are fixedly connected to one side of the front end plate 301b and one side of the rear end plate 301c, respectively.

[0080] Optionally, the base plate 301a can be a rectangular structure cut from a steel plate, used as a base for the embedded part to provide support. The base plate 301a has a front end plate 301b and a rear end plate 301c that are perpendicularly and fixedly connected to the two long sides of the base plate 301a, and two side plates 301d that are fixedly connected to the two short sides of the base plate 301a. The base plate 301a provides fixed support for the front end plate 301b, the rear end plate 301c, and the two side plates 301d, thus forming the embedded part of the bracket support in the assembly device provided in this application embodiment.

[0081] Optionally, the front end plate 301b and the rear end plate 301c can be trapezoidal structures cut from steel plates. The long sides of the front end plate 301b and the rear end plate 301c are respectively fixedly and perpendicularly to the two long sides of the base plate 301a.

[0082] Optionally, the two side plates 301d can be rectangular structures cut from steel plates. One long side of each side plate 301d can be fixedly connected to the short side of the base plate 301a. At the same time, the short sides of each side plate 301d can be fixedly connected to the front plate 301b and the rear plate 301c, respectively, so that the two side plates 301d and the base plate 301a maintain a certain angle. On this basis, the stable fixation of the base plate 301a, the front plate 301b, the side plates, and the two side plates 301d is ensured.

[0083] Optionally, since the embedded part 301 is pre-embedded in the structure, the gap of the embedded part 301 can be filled by the concrete of the structure itself, which can improve the stability of the corbel support while ensuring the integrity of the original structure.

[0084] In this embodiment, the base plate serves as the bottom of the embedded part, providing support for the front plate, the rear plate, and the two side plates. On this basis, the front plate, the two side plates, and the rear plate are fixedly connected in sequence, forming a stable structure together with the base plate. At the same time, the gaps of the embedded part are filled during the pre-embedding process, which can provide stable support for the pressure-bearing part while ensuring the integrity of the original structure.

[0085] Reference Figure 3 As shown, the pressure-bearing part 302 includes: a pressure-bearing plate 302a and a plurality of shear plates 302b.

[0086] Multiple shear plates 302b are arranged in parallel and perpendicularly pass through the front end plate 301b and the rear end plate 301c.

[0087] The pressure plate 302a is fixedly covered on top of multiple shear plates 302b, and one end of the pressure plate 302a is fixedly connected to the front end plate 301b.

[0088] Optionally, the number of shear plates 302b can be adjusted according to the magnitude of the force during actual application. This embodiment illustrates an example using three shear plates. The shear plates 302b can be quadrilateral structures cut from steel plates. The three shear plates 302b are arranged in parallel at intervals. One side of each shear plate 302b passes sequentially through the rear end plate 301c and the front end plate 301b, and is simultaneously vertically and fixedly connected to the front end plate 301b, the rear end plate 301c, and the base plate 301a. The shear plates 302b are used to connect the embedded part 301 and the pressure-bearing part 302, distributing the force of the pressure-bearing part 302 to the embedded part 301, thus realizing the supporting function of the bracket 300 on the assembled bracket 400, and simultaneously improving the shear resistance of the bracket 300.

[0089] Optionally, the pressure plate 302a can be a rectangular structure cut from a steel plate to form a plane for bearing pressure support on the assembled bracket 400. The pressure plate 302a is fixedly covered on each shear plate 302b, and one side of the pressure plate 302a is perpendicular to one side of each shear plate 302b, connecting each shear plate 302b into a whole, so that the pressure received by the pressure plate 302a can be evenly transmitted to each shear plate 302b. One side of the pressure plate 302a is fixedly connected to the rear end plate 301c to form a stable structure composed of the pressure plate 302a, the rear end plate 301c, and multiple shear plates 302b.

[0090] In this embodiment, a stable structure is formed by vertically fixing each shear plate, bearing plate, and rear end plate to each other. This distributes the force on the bearing plate evenly to the embedded part of the corbel support through the shear plate, further providing a stable support structure for the assembled bracket in the assembly device.

[0091] Reference Figure 2 As shown, the assembled bracket 400 is arranged in an inverted triangular shape on the pressure plate 302a of the pressure-bearing part 302 of the corbel support 300.

[0092] Optionally, the prefabricated bracket 400 can be fixed as a right triangle, with one right-angled side of the prefabricated bracket 400 parallel to the structure and the other right-angled side of the prefabricated bracket 400 perpendicular to the structure. The right-angled end of the prefabricated bracket 400 is located at the end away from the corbel support, and the bottom of the prefabricated bracket 400 is set on the pressure plate 302a of the pressure-bearing part 302 of the corbel support 300.

[0093] The beneficial effects of this application embodiment are that the base plate of the embedded part provides support for the front end plate, the rear end plate, and the two side plates of the embedded part. Simultaneously, the front end plate, the two side plates, and the rear end plate of the embedded part are sequentially and fixedly connected, forming a stable structure together with the base plate. Furthermore, filling the gaps in the embedded part during embedding ensures stable support of the embedded part for the bearing portion while maintaining the integrity of the original structure. Based on this, the shear plates, bearing plates, and rear end plates are vertically and fixedly connected, distributing the force of the bearing plate evenly to the embedded part of the corbel support through the shear plates. This not only provides stable support for the prefabricated bracket but also ensures the load-bearing performance of the corbel support. Moreover, placing the prefabricated bracket on the corbel support provides a stable load-bearing structure during the construction of the bridge using the cast-in-place bracket method, ensuring construction safety.

[0094] As one possible implementation method, continue to refer to Figure 3 As shown, both the front end plate 301b and the rear end plate 301c are trapezoidal, and the two ends of each side plate 301d are fixedly connected to the front end plate 301b and the rear end plate 301c along the hypotenuse of the front end plate 301b and the rear end plate 301c.

[0095] The base plate 301a has multiple through holes 301e, and each side plate 301d has multiple through holes 301e.

[0096] Optionally, the base plate 301a may have multiple through holes 301e. When the embedded part 301 is embedded in the structure, the steel bars in the structure can pass through the through holes 301e on the base plate 301a, so that the embedded part 301 of the corbel support 300 can be embedded in the structure without damaging the original structural integrity.

[0097] Optionally, multiple through holes 301e can be opened on the two side plates. When the embedded part 301 is embedded in the structure, the steel bars in the structure can pass through the through holes 301e on the two side plates 301d and the base plate 301a, so that the embedded part 301 of the corbel support 300 can be embedded in the structure without destroying the original structural integrity.

[0098] Optionally, the front plate 301b and the rear plate 301c have slots for fixing the shear plate 302b.

[0099] In this embodiment, by pre-reserving through holes on the base plate and the two side plates, the embedded parts do not need to be moved or cut off in the reinforced concrete structure of the structure itself when they are embedded into the structure. This ensures construction safety while maintaining the integrity of the original structure.

[0100] As one possible implementation method, continue to refer to Figure 3 As shown, each shear plate 302b is a right trapezoid, and the hypotenuse of the shear plate 302b is located at the end away from the embedded part 301.

[0101] Optionally, the shear plate 302b can be a right-angled trapezoidal structure cut from a steel plate. Three shear plates 302b are arranged in parallel at intervals. The right-angled sides of the three shear plates 302b pass sequentially through the slots on the rear end plate 301c and the front end plate 301b, and are simultaneously vertically and fixedly connected to the front end plate 301b, the rear end plate 301c, and the base plate 301a. The shear plate 302b is used to connect the embedded part 301 and the pressure-bearing part 302, so as to distribute the force of the pressure-bearing part 302 to the embedded part 301, thereby realizing the supporting function of the bracket 300 on the assembled bracket 400.

[0102] The specific structure of the bracket support in the assembly device has been described above. The structure of the assembled bracket will be described below.

[0103] Figure 4 This is a schematic diagram of the assembly bracket in the assembly device provided in the embodiments of this application.

[0104] As one possible implementation method, refer to Figure 4 As shown, the assembled bracket 400 includes: a horizontal bar connecting section 401, a vertical bar connecting section 402, and a diagonal bar connecting section 403.

[0105] It should be understood that since the bracket is welded on-site, it requires a certain processing cycle. After use, it can only be cut directly without any space for reuse. Therefore, the prefabricated bracket is divided into horizontal bar connection sections, vertical bar connection sections, and diagonal bar connection sections so that the prefabricated bracket can support the structure through fixing during use.

[0106] The horizontal bar connecting section 401, the vertical bar connecting section 402, and the diagonal bar connecting section 403 are detachably connected in pairs.

[0107] Optionally, the horizontal bar connecting section 401, the vertical bar connecting section 402, and the diagonal bar connecting section 403 are each part of a right triangle, and can be detachably connected to form a complete right triangle.

[0108] Optionally, the detachable connection can be achieved using bolts and nuts.

[0135] Based on the same inventive concept, this application also provides a method for determining the parameters of an assembly device, which is applied to the above-mentioned assembly device. The following describes the method for determining the parameters of an assembly device provided in this application.

[0136] Figure 7 A flowchart illustrating a parameter determination method for an assembly device provided in this application embodiment is shown below. Figure 7 As shown, the executing entity of this method can be any electronic device with processing capabilities, and the method includes:

[0137] S701. Based on the performance parameters of the structure, determine the first vertical force value and the second vertical force value of the assembly device.

[0138] For example, Figure 8 A schematic diagram of the overall force analysis of the assembly device in the method for determining the parameters of the assembly device.

[0139] It should be understood, with reference Figure 8As shown, the above-mentioned assembly device can be simplified into a triangular truss structure GOC during design calculations. In this triangular truss structure GOC, the three vertices G, O, and C are all rigid joints, and the connection points D, E, and F between the horizontal bar connection segment, the vertical bar connection segment, and the diagonal bar connection segment are all hinged. In this case, the assembly device is subjected to a first vertical force F1 and a second vertical force F2 from the bridge cap beam of the structure during construction. The performance parameters of the bridge cap beam of the structure can be obtained through design before construction, and correspondingly, the first vertical force F1 and the second vertical force F2 can be obtained from the production parameters of the bridge cap beam of the structure.

[0140] Optionally, the first vertical force value F1 and the second vertical force value F2 in the assembly device can be determined by using the performance parameters of the bridge cap beam of the pre-designed structure.

[0141] In this embodiment, the vertical force value of the assembly device is determined by the performance parameters of the structure, which ensures that the data source of the parameter determination method of the assembly device provided in this application is accurate and guarantees the accuracy of subsequent processing steps.

[0142] S702. Determine the first horizontal force value and the second horizontal force value based on the length values ​​of each part of the prefabricated bracket in the pre-designed assembly device, as well as the first force value and the second force value.

[0143] For example, continue to refer to Figure 8 As shown, it should be understood that in this triangular truss structure GOC, the point where the first vertical force F1 acts on the horizontal connecting segment is J, and the point where the second vertical force F2 acts on the horizontal connecting segment is K. At this time, the sum of the lengths l1 of line segment OK, l2 of line segment KJ, and l3 of line segment CJ is the length of the horizontal sub-segment in the horizontal connecting segment. Correspondingly, the sum of the lengths b1 of the first diagonal sub-segment CD, b2 of the diagonal connecting segment DE, and b3 of the second diagonal sub-segment EG of the vertical connecting segment in the horizontal connecting segment is the length of the hypotenuse CG in the triangular truss structure GOC. Correspondingly, the sum of the lengths h1 of the vertical sub-segment OF in the horizontal connecting segment and the length h2 of the vertical sub-segment FG in the vertical connecting segment is the length of the right-angled side OG in the triangular truss structure GOC. That is to say, in the pre-design, the lengths and relationships of l1, l2, and l3, the lengths and relationships of b1, b2, and b3, and the lengths and relationships of h1 and h2 can be obtained.

[0144] Meanwhile, since the prefabricated bracket is fixed to the pier body of the structure by two fasteners and the pressure-bearing part of the corbel support, the prefabricated bracket has a first horizontal force value F at point O. x1 There is a second horizontal force F at point G. x2 and longitudinal bearing capacity Fy1 Given the known lengths and relationships of l1, l2, and l3, the lengths and relationships of b1, b2, and b3, and the lengths and relationships of h1 and h2, and combining the first vertical force value F1 and the second vertical force value F2 obtained in step S701 above, it is possible to determine the first horizontal force value F. x1 and the second horizontal force value F x2 To be determined.

[0145] For example, in this triangular truss structure GOC, the forces acting on the prefabricated brackets satisfy the following formula:

[0146] ,Right now (1)

[0147] ,Right now (2)

[0148] ,Right now (3)

[0149] The following formula can be obtained from the above formulas (1), (2) and (3):

[0150] (4)

[0151] (5)

[0152] (6)

[0153] That is, the first horizontal force value F x1 The second horizontal force value F can be expressed by the above formula (5). x2 It can be expressed using the above formula (6).

[0154] In this embodiment, the horizontal force is represented by the length and vertical force value of each part of the pre-designed assembled bracket. This allows for the determination of the material parameters of the fasteners in the assembly device based on the horizontal force values, thus meeting construction needs and ensuring construction safety. Simultaneously, the length of each part can be adjusted based on the above formula to meet the material parameter requirements of the fasteners in the pre-assembled bracket.

[0155] S703. Determine the force values ​​of each part of the prefabricated bracket based on the first vertical force value, the second vertical force value, the first horizontal force value, the second horizontal force value, the length values ​​of each part of the prefabricated bracket, and the angle values ​​of the prefabricated bracket.

[0156] It should be understood that after determining the stress on the overall GOC (Gate of Construct) of the prefabricated bracket, the GOC can be divided into a first part CDOF (Conductivity of Fiber) and a second part FGE (Frustration of Frame). Analyzing the stress on the first part CDOF and the second part FGE separately allows for the determination of the material parameters of the prefabricated bracket based on the stress conditions of each part, thus meeting construction needs and ensuring construction safety. Simultaneously, the lengths of each part can be adjusted based on the analysis results to meet the material parameter requirements of the prefabricated bracket.

[0157] For example, Figure 9 A schematic diagram of the force analysis of the first part of the assembly bracket, CDOF, in the method for determining the parameters of the assembly device.

[0158] Reference Figure 9 As shown, it should be understood that in the triangular truss structure GOC, since the vertical segment OF in the horizontal connection section is connected to the vertical segment FG in the vertical member connection section by hinges, and the first diagonal segment CD in the horizontal connection section is connected to the diagonal member connection segment DE by hinges, the connection point F in the first part CDOF has a horizontal force value F. fx1 and vertical force value F fy1 The connection point D has an oblique force F. d Meanwhile, if the interior angles in the triangular truss structure GOC are denoted as α and β, then the forces acting on the first part of the prefabricated bracket, CDOF, satisfy the following formula:

[0159] ,Right now (7)

[0160] ,Right now (8)

[0161] ,Right now (9)

[0162] The following formula can be obtained from the above formulas (7), (8) and (9):

[0163] (10)

[0164] (11)

[0165] (12)

[0166] In the first part of the assembled bracket, CDOF, the horizontal force value F fx1 The vertical force F can be expressed by the above formula (12). fy1 The oblique force F can be expressed by the above formula (11). dIt can be expressed by the above formula (10).

[0167] For example, Figure 10 A schematic diagram of the force analysis of the second part of the assembly bracket, FGE, in the method for determining the parameters of the assembly device.

[0168] Reference Figure 10 As shown, it should be understood that in the triangular truss structure GOC, since the vertical segment OF in the horizontal connection section is connected to the vertical segment FG in the vertical member connection section by hinges, and the second diagonal segment EG in the vertical member connection section is connected to the diagonal member connection section DE by hinges, the connection point F in the second part FGE has a horizontal force value F. fx2 and vertical force value F fy2 The connection point E has an oblique force value F. e At this point, the forces acting on the second part FGE of the prefabricated bracket satisfy the following formula:

[0169] ,Right now (13)

[0170] ,Right now (14)

[0171] ,Right now (15)

[0172] The following formula can be obtained from the above formulas (13), (14) and (15):

[0173] (16)

[0174] (17)

[0175] (18)

[0176] In the second part of the assembled bracket, FGE, the horizontal force value F fx2 The vertical force F can be expressed by the above formula (16). fy2 The oblique force F can be expressed by the above formula (17). e It can be expressed by the above formula (18).

[0179] For example, the bending moment diagram, shear force diagram and axial force diagram of the triangular truss structure GOC can be drawn by the above formulas (4)-(6), (10)-(11) and (16)-(17). Figure 11 This is the bending moment diagram for the triangular truss structure GOC. Figure 12 This is the shear force diagram for the triangular truss structure GOC. Figure 13 This is the axial force diagram for the triangular truss structure GOC.

[0194] In this embodiment, the horizontal force is represented and analyzed by the length and vertical force values ​​of each part of the pre-designed assembly device. This allows for the determination of the horizontal parameter values ​​of the horizontal rod connection section, the vertical parameter values ​​of the vertical rod connection section, and the inclined parameter values ​​of the inclined rod connection section of the prefabricated bracket. Consequently, the material parameters of the fasteners in the assembly device can be determined to meet construction needs and ensure construction safety.
