Description

Technical Field

[0001] The present invention relates to the technical field of structural assembly construction, and in particular to a device and method for reducing internal stress generated during structural assembly. Background Art

[0002] Various large equipment and buildings are assembled from multiple groups of component structures. During the assembly process, various internal stresses are inevitably present. These internal stresses, more or less, are gradually released during the later normal use process. During the release process, it will cause changes in the overall dimensions of the structure.

[0003] For example, when assembling the structures of columns and beams, the overall structure consists of columns, beams, and corresponding accessories. The connection methods between columns and beams, and between columns and foundations are rigid connections. Since there will be accessories on the beam structure, pre-deformation is left on the beam during the manufacturing process to offset part of the deformation during installation. As Figure 2 shown, the column is placed vertically as a support column. Guide positioning plates are fixedly provided at the corresponding positions of the two ends of the beam and its accessories with respect to the column. The beam is lowered onto the upper opening of the column by means of hoisting, so that the guide positioning plates are aligned and installed in cooperation with the column. After adjusting the structure to control the dimensions, the rigid connection work is completed.

[0004] However, due to the pre-deformation left on the beam in the early stage, presenting a certain upward arch shape, when hoisting and installing the beam and its accessories, the guide positioning plates fixed on the beam are aligned with the column, and the contact range is determined. When the hoisting equipment is removed, the self-weight of the beam and its accessories will cause the prefabricated camber of the beam to gradually disappear. Under the action of gravity, the beam will deform in the vertical direction, resulting in an extension of the beam in the length direction, thereby causing a horizontal displacement of the column through the guide positioning plates or through the frictional action of the contact part on the column body, resulting in assembly errors in perpendicularity and internal stress in the structure. Therefore, in the existing structural beam-column assembly method, there is a problem that the prefabricated camber of the beam itself is not released completely, so that the load brought by the upper beam to the column cannot be transmitted along the axis of the column, causing bending moment inside the column; for the assembly between many large equipment and building structures, the same problem exists. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a device and method for reducing internal stress generated during structural assembly. The support assembly is used as a temporary support structure. When assembling two structural members, the guide plate slides or rotates relative to each other in the guide groove to relieve the displacement of another structural member caused by the outward extension of the end of the structural member due to its own weight, thereby generating a greater influence of bending moment, and achieving the purpose of releasing internal stress when assembling two different structural members.

[0006] To achieve the above purpose, the present invention is realized through the following technical solutions:

[0007] In a first aspect, a device for reducing internal stress generated during structural assembly includes a support assembly composed of an upper support and a lower support. The upper support is used for fixedly connecting with a first structural member. The upper support is provided with a pair of ear plates. Circular holes are provided on the ear plates, and a guiding groove is formed between the ear plates. The lower support is used for fixedly connecting with a second structural member. The lower support has a guiding plate. An oblong hole is provided on the guiding plate. One end of the guiding plate extends into the guiding groove, and the oblong hole is matched with the circular hole through a pin shaft so that the guiding plate has a set movement space in the guiding groove. The guiding plate and the guiding groove can slide or rotate relative to each other. The support assembly serves as a temporary support structure to release internal stress when assembling two different structural members.

[0008] As a further implementation manner, the length of the oblong hole is greater than the diameter of the circular hole; the length direction of the oblong hole is the horizontal direction.

[0009] As a further implementation manner, the upper support includes a pair of oppositely arranged upper fixing structures. A pair of oppositely arranged ear plates are provided between the two upper fixing structures. The guiding groove between the ear plates is for the guiding plate to extend. The circular holes are correspondingly arranged at the lower end positions of the ear plates, and the height of the circular holes is lower than the bottom end of the upper fixing structures.

[0010] As a further implementation manner, the upper fixing structure is a plate structure. The upper support is fixedly connected with the first structural member through the upper fixing structure or the ear plates. The distance between the top ends of the two upper fixing structures is less than the distance between the bottom ends;

[0011] The top end of the ear plate is higher than the top end of the upper fixing structure, or lower than the top end of the upper fixing structure, or flush with the top end of the upper fixing structure.

[0012] As a further implementation manner, the lower support includes a lower fixing structure. The lower fixing structure is arranged on one side of the guiding plate and close to the lower end of the guiding plate; the lower support is fixedly connected with the second structural member through the lower fixing structure or the guiding plate.

[0013] As a further implementation manner, the lower fixing structure is a plate structure, and the lower fixing structure is vertically connected with the guiding plate.

[0014] As a further implementation manner, the top end of the guiding plate forms a guiding head for extending into the guiding groove and having a set movement space in the guiding groove.

[0015] As a further implementation manner, the oblong hole is arranged at a position close to the middle of the guiding plate, and the oblong hole is close to the top end position of the lower fixing structure.

[0016] As a further implementation manner, the lower fixing structures are arranged in pairs on one side of the guiding plate. The distance between the top ends of the lower fixing structures is greater than the distance between the bottom ends; anti-friction materials are coated on the oblong hole, the circular hole, and the pin shaft.

[0017] Second aspect, a method for reducing internal stress generated during structural assembly, using any of the devices for reducing internal stress generated during structural assembly described above, includes the following steps:

[0018] According to the splicing nature of the first structural member and the second structural member, select appropriate upper and lower supports, and determine the installation position of the support assembly at a position close to the splicing node of the structural members; fix the upper support on the first structural member and fix the lower support on the second structural member. When splicing the two structural members by hoisting, during the process, it is necessary to ensure that the end of the guide plate is inserted into the guide groove, and use a pin to connect the long circular hole and the circular hole, so that the guide plate and the guide groove can slide or rotate relative to each other. Remove the hoisting equipment. Under the action of the self-weight of the structural members, the local internal stress caused by the load of the structural members is released through the support assembly, and then the connection work between the structural members is carried out.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The support assembly of the present invention serves as a temporary support structure. When assembling two structural members, through the cooperation of the pin with the long circular hole and the circular hole, the guide plate slides or rotates relative to each other in the guide groove to relieve the displacement of another structural member caused by the extension of the end of the structural member due to its own weight, thereby generating a greater bending moment. By using the support assembly to assist in assembling different structural members, the purpose of releasing internal stress during the assembly of two different structural members is achieved; for the upper structural member after releasing the internal stress, the load can be transmitted to the lower structural member more evenly, solving the problems of assembly errors in the verticality of structural members and internal stress in the existing structural assembly methods.

[0021] 2. The dimensions and shapes of the fixed structure of the support assembly of the present invention, the dimensions and shapes of the guide plate and the ear plate can be adjusted according to different structural members to be spliced. Therefore, it can be applied not only to the scenario of beam-column connection, but also to the scenario of large equipment assembly, etc.; for metal structural members, the support assembly can be welded to the structural members; for concrete structural members, the corresponding structure of the support assembly can be bent and connected to the embedded bolts of the structural members. The usage scenarios are extensive, and the support assembly can be reused as a temporary support. BRIEF DESCRIPTION OF THE DRAWINGS

Specific Embodiments

[0039] It should be noted that the following detailed description is exemplary and is intended to provide further illustration of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0040] Such as Figure 2As shown in the figure, in the prior art, columns are vertically placed as support columns, and guiding and positioning plates are fixedly provided at the positions corresponding to the columns at both ends of the beam and its accessories. The beam is placed on the upper opening of the column by means of hoisting, so that the guiding and positioning plates are aligned and installed in cooperation with the columns. After adjusting the structural control dimensions, the rigid connection work is completed. However, due to the pre-deformation left in the beam in the early stage, when the hoisting equipment is removed, the self-weight of the beam and its accessories will cause the precast camber of the beam to gradually disappear. Under the action of gravity, the beam will deform in the vertical direction, resulting in the elongation of the beam in the length direction. As a result, through the guiding and positioning plates or the frictional action of the contact part on the column, the horizontal displacement of the column is caused, so that the load brought by the upper beam to the column cannot be transmitted along the axis of the column, causing the problem of bending moment generated inside the column.

[0041] Embodiment 1

[0042] In a typical implementation manner of the present invention, with reference to Figure 1 Figure 3 Figure 10 As shown in the figure, a device for reducing internal stress generated during structural assembly includes a support assembly 3 composed of an upper support 31 and a lower support 32. The upper support 31 is used for fixedly connecting with the first structural member 4. The upper support 31 is provided with a pair of ear plates 311. Circular holes are provided on the ear plates 311, and a guiding groove is formed between the ear plates 311; the lower support 32 is used for fixedly connecting with the second structural member 5. The lower support 32 has a guiding plate 321. A long circular hole 323 is provided on the guiding plate 321. One end of the guiding plate 321 extends into the guiding groove, and the long circular hole 323 is matched with the circular hole 312 through a pin shaft 33 to enable the guiding plate 321 to have a set activity space in the guiding groove, so that the guiding plate and the guiding groove can relatively slide or rotate; the support assembly serves as a temporary support structure to release internal stress when two different structural members are assembled.

[0043] As shown in Figures 3(a) and 3(b), the upper support 31 and the lower support 32 form a set of hinged structures, and the circular holes on the upper support 31 and the long circular hole 323 on the lower support 32 are hinged through a pin shaft.

[0044] Specifically, as shown in Figures 4(a) and 4(b), the upper support 31 includes a pair of relatively arranged upper fixed structures 313. A pair of relatively arranged ear plates 311 are provided between the two upper fixed structures 313. The ear plates are arranged in parallel. The through groove between the two ear plates 311 serves as the guiding groove for the guiding plate 321 to extend, and the guiding plate 321 can move in this groove.

[0045] The circular holes 312 are correspondingly arranged at the lower end positions of the ear plates 311. The positions of the circular holes 312 on the two ear plates 311 correspond to each other to facilitate cooperation with the same pin shaft 33. One end of the ear plate 311 with a circular hole is smaller at the bottom and larger at the top. In this embodiment, this end has a triangular structure.

[0046] As shown in Fig. 4(a), the height of the round hole on the ear plate 311 is lower than the bottom end of the upper fixing structure, and the distance between the top ends of the two upper fixing structures is smaller than the distance between the bottom ends, presenting an inverted V shape to ensure that the guide plate has sufficient movement space.

[0047] In an optional example, the upper fixing structure is a plate structure. As shown in Fig. 4(b), the upper fixing structure 313 is a rectangular plate, and the width of the rectangular plate 313 is greater than the distance between the ear plates, such that the two side edges of the rectangular plate protrude beyond the outer side surfaces of the ear plates. The lower end of the ear plate 311 is located below the rectangular plate.

[0048] The guide plate 321 can be inserted into the guide groove formed by the ear plate 311 and the rectangular plate and has movement space here, thereby enabling the structural member to release internal stress.

[0049] As Figure 6 shown, the upper support 31 can be connected to the first structural member 4 through the rectangular plate. When connecting, the upper fixing structure 313 is perpendicularly welded to the side surface of the first structural member 4, and the ear plate is parallel to and located outside this side surface of the first structural member 4.

[0050] As shown in Fig. 5(a) and Fig. (b), the lower support 32 includes a pair of oppositely arranged lower fixing structures 322, and the lower fixing structures 322 are arranged on one side of the guide plate 321 and close to the lower end of the guide plate.

[0051] In this example, the lower fixing structure 322 is also a rectangular plate structure. The distance between the two lower fixing structures 322 is smaller than the width of the lower end of the guide plate 321. The lower fixing structures 322 are perpendicularly welded to the guide plate 321 and not welded to the side edges of the guide plate 321. The lower support 32 is preferably a symmetric structure.

[0052] The top end of the guide plate 321 forms a guide head 3211 for extending into the guide groove. The shape of the guide head 3211 is set as a trapezoidal structure and is adapted to the inverted V-shaped upper fixing structure 313. As shown in Fig. 3(a), after the guide head at the top end of the guide plate extends into the guide groove, the left and right side edges of the guide head 3211 are approximately parallel to and do not contact the upper fixing structure 313, such that the guide head 3211 can slide horizontally in the guide groove, and relative rotation between the guide head and the upper support 31 can be achieved through the pin shaft 33.

[0053] As shown in Fig. 3(a) and Fig. 5(a), the lower fixing structures 322 are distributed in an inverted V shape, that is, the distance between the lower top ends of the two rectangular plates is smaller than the distance between the bottom ends. After the upper and lower supports are matched, the lower end of the ear plate is located at the top end of the lower fixing structure 322 and higher than the top end of the lower fixing structure 322. The inverted V-shaped distribution of the lower fixing structure 322 can ensure that when the upper and lower supports rotate relative to each other, the lower end of the ear plate will not be blocked by the top end of the lower fixing structure 322, and the top end of the lower fixing structure 322 gives way to the movement space at the bottom end of the ear plate.

[0054] The oblong hole 323 is provided at a position close to the middle of the guide plate 321. The oblong hole 323 is arranged at a position close to the top of the lower fixing structure 322 and is higher than the top of the lower fixing structure 322. After the round hole 312 at the bottom end of the ear plate 311 is fitted, it can ensure that the upper and lower supports rotate and slide relative to each other within a sufficient space range.

[0055] As shown in FIG. 5, the first structural member 4 is used as the upper structural member, and the second structural member 5 is used as the lower structural member. The upper structural member 4 has a prefabricated camber. When the support assembly 3 of the present embodiment is used as a temporary support for assembly, the sides of the first structural member 4 and the second structural member 5 can be aligned. The inner side of the upper fixing structure 313 of the upper support 31 in the vertical direction is welded to the outer side of the first structural member 4. The lower fixing structure 322 of the lower support 32 is located inside the guide plate 321 and is welded to the side of the second structural member 5.

[0056] It should be noted that the welding positions of the upper and lower supports are calculated in advance, and the movement range of the structural position after docking caused by the prefabricated camber of the structural member is covered. Therefore, the size of the oblong hole 323 is also set in advance. The length of the oblong hole 323 is greater than the diameter of the round hole 312 to facilitate the sliding of the pin shaft 33 in the oblong hole 323. The length direction of the oblong hole 323 in this example is the horizontal direction. When assembling different structural members, the length direction of the oblong hole 323 can be adjusted correspondingly.

[0057] After the first structural member 4 and the second structural member 5 are hoisted and docked, the guide head extends into the guide groove, and the pin shaft is installed into the oblong hole 323 and the round hole 312. Specifically, when the first structural member 4 is the beam and its accessories 2, and the second structural member 5 is the column 1, the installation position of the support assembly 3 can be referred to Figure 1 as shown. At this time, the assembled states of the upper and lower supports are shown in FIGS. 3(a) and 3(b).

[0058] After the hoisting equipment is removed, due to the self-weight of the beam and its accessories 2, the beam and its accessories 2 deform in the vertical direction under the action of gravity, resulting in the elongation of the beam in the length direction. At this time, the beam and its accessories 2 drive the upper support 31 to have a tendency to extend outwards. Under the action of the oblong hole 323, the round hole 312 and the pin shaft 33, the ear plate 311 drives the pin shaft 33 to displace slightly in the horizontal direction within the oblong hole 323. During the displacement process, the prefabricated camber of the beam and its accessories 2 decreases, which will cause the upper and lower supports to rotate relative to each other with the position of the pin shaft 33 as the rotation point and finally tend to be stable.

[0059] Using the support assembly 3 of this example as a temporary support, when docking two structural members, while reducing the precast camber of the structural members, it will not cause displacement of the body of another structural member, and thus will not have a greater bending moment effect. The internal stress is effectively released. The load of the first structural member on the second structural member after releasing the internal stress can be basically perpendicular to the axis of the second structural member. Then, the formal installation and fixation work between the structural members can be carried out. Finally, the support assembly can be removed and reused.

[0060] As Figures 7 - 8 shown, take the connection structure of the beam and its accessories 2 and the column 1 as an example. Figure 7 In it, the upper and lower supports can be installed at the front side position of the structural member, that is, at the position of the first installation point 6. Figure 8 In it, the upper support can be located at the bottom surface or the side surface of the end of the beam and its accessories 2, and the lower support can be installed on the side of the column 1 close to the beam and its accessories 2, that is, at the position of the second installation point 7. Figure 10 It shows the connection method of releasing internal stress between the column and the foundation using the support assembly. The support assembly 3 is located at the position of the third installation point 8.

[0061] When using the support assembly to assist the beam-column structure, the support assembly serves as a temporary support. Due to its own weight, the beam and its accessories 2 will extend in the length direction of the beam. The pin on the upper support ear plate can slide relative to the long circular hole in the lower support, thereby releasing the internal stress of the beam and its accessories 2. The beam and its accessories 2 will not cause horizontal displacement at the top of the column 1, so the column 1 is not affected by the bending moment, and the assembly error of the verticality of the column 1 structure will not be caused. The column 1 will not generate internal stress, ensuring the stability of the subsequent structural connection.

[0062] It can be understood that in other examples, when the structural member is not a metal structural member, for example, the structural member is a concrete structure, the upper and lower fixing structures of the upper support 31 and the lower support 32 can be set as bent plate structures, such as L-shaped, and the positions of the embedded bolts need to be calculated on the structural member for bolt embedding, so that the support assembly can be fixed to the embedded bolts through the bent plate to install the upper support 31 and the lower support 32 to the target position.

[0063] Therefore, the shapes of the upper fixing structure 313 and the lower fixing structure 322 are not specifically limited and can be adjusted according to the actual situation of the structural members to be assembled, aiming to effectively install and fix the upper and lower supports.

[0064] As shown in Figure 3, the top of the ear plate 311 is flush with the top of the upper fixing structure 313, and the upper fixing structure 313 is preferably the connection object with the structural member.

[0065] In an alternative example, as Figure 8As shown in the figure, it is possible to consider installing the upper support 31 at the middle position of the bottom surface of the end of the beam and its accessories 2. At this time, the top of the ear plate 311 is flush with the top of the upper fixing structure 313, the top of the ear plate 311 is higher than the top of the upper fixing structure 313, or lower than the top of the upper fixing structure 313. In all these cases, the fixing of the upper support 31 can be achieved. Therefore, in some cases, the top of the ear plate 311 can be used as the object to be connected to the structural member. The top of the ear plate can also be bent in different scenarios to facilitate connection with the embedded screws of the concrete structural member.

[0066] In an alternative example, the sides of the positions where the first structural member 4 and the second structural member 5 install the support assembly do not need to be aligned and may not be in the same plane. According to the different assembly conditions between the structural members, the dimensions of each structural member of the upper and lower supports can be adjusted. Therefore, the dimensions of the structural members of the upper and lower supports are not specifically limited. As long as the guiding head 3211 can be inserted into the guiding groove, and the oblong hole 323 on the guiding plate 321 and the round hole 312 on the ear plate 311 are matched by the pin shaft 33, the relative sliding and relative rotation of the upper and lower supports can be achieved, thus achieving the purpose of releasing the internal stress in the structural members.

[0067] Figure 8 In the figure, when the lower support 32 is installed on the side of the column 1 close to the beam, the lower support 32 is connected to the column 1 through the guiding plate. As Figure 9 shown, the dimension of one side at the bottom end of the guiding plate 321 is increased for welding with the side of the structural member or fixing with the embedded bolt of the structural member through bending. At this time, the guiding plate serves as the object connected to the structural member, and the lower fixing structure does not participate in the connection with the structural member. Or, in order to improve the connection strength, the lower fixing structure 322 close to the structural member in Figure 9 the figure can be set as a U-shaped plate. The opening of the U-shaped plate faces the structural member, and it is welded to the structural member or further bent and fixed to the embedded bolt to improve the fixing strength of the lower support.

[0068] Therefore, in the upper support 31 and the lower support 32 of this example, the upper fixing structure 313, the ear plate 311, the guiding plate 321, and the lower fixing structure 322 can all be welded to the side of the structural member or achieve screw connection through bending in different situations. Therefore, the dimensions and shapes of each structure of the upper and lower supports need to be calculated according to the specific conditions of the assembled structural members.

[0069] In an alternative example, anti-friction materials are coated on the oblong hole 323, the round hole 312, and the pin shaft 33 to reduce the friction coefficient, making it easier for the upper support 31 and the lower support 32 to slide relative to each other, better releasing the internal stress in the structure and achieving the purpose of reducing the internal stress generated during structural assembly.

[0070] During the assembly of this embodiment, the support assembly 3 is installed at the force transmission center of the structural member and can be used as a temporary support. After releasing the local internal stress caused by the upper load, the connection work is carried out. This device can be made into a standard tooling according to common structures, is detachable, and can be reused multiple times.

[0071] The oblong hole 323 in the lower support 32 is to ensure relative sliding to release the horizontal constraint (free sliding can be ensured by applying other materials with reduced friction coefficient). The round hole 312 and the pin shaft 33 are connected in cooperation with the oblong hole 323 to ensure that the upper and lower supports can rotate relative to each other. The guide plate 321 and the guide groove can be used for guiding. Ensure that the internal deformation and stress of the structure are reduced as much as possible during manufacturing, and improve the safety and reliability of the structure.

[0072] It can be understood that the device for reducing the internal stress generated during the assembly of the structure in this example can not only be used for releasing the internal stress during the assembly of beam-column structures, Figures 7 - 10 Only three implementation manners are shown. In addition, it can also be used at the connection nodes of various structural members in other large-scale equipment or construction fields. The size and shape of the support assembly 3 can be adjusted according to the actual situation and calculation. As long as it is ensured that after the upper and lower supports are installed, the upper and lower supports can slide and rotate relative to each other based on the oblong hole and the pin shaft, it belongs to the protection scope of this solution.

[0073] Embodiment Two

[0074] In a typical implementation manner of the present invention, referring to Figure 1 Figure 3- Figure 10 As shown, a method for reducing the internal stress generated during the assembly of the structure uses the device for reducing the internal stress generated during the assembly of the structure as described in Embodiment One, and includes the following steps:

[0075] According to the splicing nature of the first structural member and the second structural member, determine the installation positions of the upper support and the lower support on the structural member, and select appropriate upper support 31 and lower support 32, or calculate the shape and size of the support assembly 3 to manufacture appropriate upper support 31 and lower support 32. At the position close to the splicing node of the structural member, according to the determined installation position; fix the upper support 31 on the first structural member 4, fix the lower support 32 on the second structural member 5. When splicing the two structural members by hoisting, it is necessary to ensure that the end of the guide plate 321 is inserted into the guide groove during the process, and connect the oblong hole 323 and the round hole 312 with the pin shaft 33, so that the guide plate 321 and the guide groove can slide or rotate relative to each other. Remove the hoisting equipment. Under the action of the self-weight of the structural member, the local internal stress caused by the load of the structural member is released through the support assembly, and then the connection work between the structural members is carried out.

[0076] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and variations can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
