Description

Technical Field

[0001] The invention relates to a connection and fixing structure and a green assembled building wall panel, belonging to the technical field of building wall panels. Background Art

[0002] With the vigorous promotion of green prefabricated building systems in recent years, the use of prefabricated wall panels for the exterior walls of buildings such as concrete and light steel structures has become increasingly common. Green prefabricated buildings shift much of the on-site work involved in traditional construction methods to the factory, where building components and accessories are processed and manufactured, transported to the construction site, and assembled and installed on-site using reliable connection methods. When light steel wall panels are connected to the outer steel beams via mounting structures, the outer steel beams can experience installation errors during construction. The size of the wall panels and the embedded components within them can also experience manufacturing and positioning errors during factory production, as well as construction errors during on-site hoisting. Therefore, error adjustments are required when connecting the wall panels to the outer steel beams.

[0003] In order to adjust the error, the existing technology, such as Chinese Patent 202110064460.0, adopts a structure that matches a bolt with a waist-shaped hole. By loosening the bolt nut, the position of the bolt screw in the waist-shaped hole is changed to achieve the error adjustment. However, this method has the following disadvantages: the locking force is provided only by the nut. When the wall panel is subjected to external loads (such as earthquake loads), the wall panel is prone to relative movement with the steel beam, resulting in poor reliability of the wall panel after installation.

[0004] Therefore, in order to adjust the error and ensure the reliability of the wall panels after installation, a new optimized connection and fixing structure and a green prefabricated building wall panel are needed. Summary of the Invention

[0086] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the connection and fixing structure and the green prefabricated building wall panel of the present invention are specifically described below in combination with embodiments and drawings.

[0087] This embodiment provides a connection and fixing structure and a green prefabricated building wall panel that can adjust errors while ensuring the reliability of the wall panel after installation.

[0088] Figure 1 It is a schematic diagram of the three-dimensional structure of the green prefabricated building wall panel in an embodiment of the present invention.

[0089] like Figure 1 As shown, the green prefabricated building wall panel 100 of this embodiment includes a steel beam 100a, a wall panel 100b and a connecting and fixing structure 100c. The connecting and fixing structure 100c is used to install the wall panel 100b on the steel beam 100a.

[0090] In this embodiment, there are two sets of connecting and fixing structures 100c, one of which is located at the top of the steel beam 100a and connects to the upper portion of the wall panel 100b during installation, and the other set is located at the bottom of the steel beam 100a and connects to the upper portion of the wall panel 100b during installation. The two sets of connecting and fixing structures 100c are symmetrically arranged relative to the centerline of the height direction of the steel beam 100a. Of course, in other embodiments, only one set of connecting and fixing structures 100c can be provided, and a horizontal plate can be added in the middle of the height direction of the steel beam 100a. The connecting and fixing structures 100c are located on this horizontal plate and connect to the middle portion of the wall panel 100b during installation.

[0091] Figure 2 It is a schematic diagram of the three-dimensional structure of the connection and fixing structure in an embodiment of the present invention.

[0092] like Figure 2 As shown, the connection and fixing structure 100c includes a wall panel connector 10, a steel beam connector 20, a fastening assembly 30 and an adjustment assembly 40. The wall panel connector 10 is used to connect to the wall panel 100b. The steel beam connector 20 is used to connect to the steel beam 100a. The fastening assembly 30 is used to indirectly fix the wall panel connector 10 to the steel beam connector 20, and includes a support member 31 and a movable pressing member 32. The support member 31 is indirectly or directly provided on the steel beam connector 20, and is used to support a portion of the wall panel connector 10. The movable pressing member 32 is indirectly or directly provided on the steel beam connector 20 and is located above the support member 31, and is used to cooperate with the support member 31. The movable pressing member 32 has at least a pressing position for cooperating with the support member 31 to press a portion of the wall panel connector 10 between the two, and a release position for allowing the wall panel connector 10 to be displaced along the first direction under the action of an external force. When the movable pressing member 32 is in the pressing position or the released position, the wall panel connector 10 is fixedly connected to the support member 31 in the first direction. The adjustment assembly 40 is used to adjust the position of the support member 31 relative to the steel beam connector 20 along the first direction when the movable pressing member 32 is in the released position, and to limit the displacement of the support member 31 relative to the steel beam connector 20 along the first direction when the movable pressing member 32 is in the released position.

[0093] It can be understood that when the error needs to be adjusted, the movable clamping member 32 is first placed in the released position, and then the position of the support member 31 relative to the steel beam connector 20 is adjusted along the first direction by the adjustment component 40, so that the position of the wall panel connector 10 relative to the steel beam connector 20 can be adjusted along the first direction, and then the position of the wall panel 100b relative to the steel beam 100a can be adjusted along the first direction, thereby achieving the adjustment of the error. After the adjustment, the movable clamping member 32 is placed in the clamping position, and in this position, the part of the wall panel connector 10 is pressed between the two by the cooperation between the movable clamping member 32 and the support member 31, so that The wall panel connector 10 is fixed between the movable pressing member 32 and the supporting member 31, thereby limiting the displacement of the wall panel connector 10 relative to the steel beam connector 20 along the first direction, thereby fixing the wall panel connector 10 on the steel beam connector 20. At the same time, the adjusting component 40 can limit the displacement of the supporting member 31 relative to the steel beam connector 20 along the first direction, thereby limiting the displacement of the wall panel connector 10 relative to the steel beam connector 20 along the first direction. Therefore, the locking of the wall panel connector 10 in the first direction can be achieved through the cooperation of the pressing component and the adjusting component 40, thereby ensuring the reliability of the wall panel 100b after installation.

[0094] Figure 3 1 is a schematic diagram of the three-dimensional structure of a wall panel connector according to an embodiment of the present invention; Figure 4 It is a schematic diagram of the three-dimensional structure of the connection fixing structure without the wall panel connecting piece in an embodiment of the present invention.

[0095] like Figures 3 and 4 As shown, the wall panel connector 10 includes a wall panel connector portion 11, a connecting protrusion 12, and a main body 13. The wall panel connector portion 11 is disposed at a first end of the wall panel connector 10 and is configured to connect to the wall panel 100b. The connecting protrusion 12 is disposed at a second end of the wall panel connector 10 and extends along a first direction for connection to the fastening assembly 30. The main body 13 is disposed between the wall panel connector portion 11 and the connecting protrusion 12. An installation space 14 is formed between the support member 31 and the movable pressing member 32 to accommodate portions of the connecting protrusion 12 and the main body 13.

[0096] It can be understood that when the connecting protrusion 12 is located in the installation space 14, the connecting protrusion 12 can be pressed between the supporting member 31 and the movable pressing member 32 through the cooperation between the two, thereby pressing part of the wall panel connecting member 10 between the supporting member 31 and the movable pressing member 32, thereby fixing the wall panel connecting member 10 on the steel beam connecting member 20.

[0097] In this embodiment, the wall panel connecting portion 11 extends into the interior of the wall panel 100b and is connected to the light steel keel structure in the wall panel 100b. The connection method can be welding, threaded connection, etc.

[0098] In this embodiment, the wall panel connector 10 , the support member 31 and the movable pressing member 32 are all plate members, all of which extend along the first direction, and the wall panel connecting portion 11 , the connecting protrusion 12 and the main body 13 are integrally formed.

[0099] Figure 5 is a side structural diagram of a connecting and fixing structure in an embodiment of the present invention; Figure 6 It is a schematic diagram of the three-dimensional structure of the movable pressing member in an embodiment of the present invention.

[0100] like Figures 5 and 6 As shown, a first recess 311 is provided on the surface of the support member 31 facing the movable pressing member 32, and a second recess 321 is provided on the surface of the movable pressing member 32 facing the support member 31. The connecting protrusion 12 includes a first portion 121 and a second portion 122. The inner shape of the first recess 311 matches the outer shape of the first portion 121 of the connecting protrusion 12, and the inner shape of the second recess 321 matches the outer shape of the second portion 122 of the connecting protrusion 12. When the movable pressing member 32 is in the pressing position, the outer surface of the first portion 121 of the connecting protrusion 12 and the inner surface of the first recess 311 fit together under a certain pressure, and the outer surface of the second portion 122 of the connecting protrusion 12 and the inner surface of the second recess 321 fit together under a certain pressure. When the movable pressing member 32 is in the release position, the outer surface of the first portion 121 of the connecting protrusion 12 is in sliding fit with the inner surface of the first recess 311 , and the outer surface of the second portion 122 of the connecting protrusion 12 is in sliding fit with the inner surface of the second recess 321 .

[0101] It can be understood that when the movable pressing member 32 is in the pressing position, pressure can be applied to the first part 121 and the second part 122 of the connecting protrusion 12 respectively through the cooperation between the first recess 311 and the second recess 321, so that the connecting protrusion 12 can be pressed between the support member 31 and the movable pressing member 32, and when the movable pressing member 32 is in the release position, the connecting protrusion 12 can slide against the first recess 311 and the second recess 321 under the action of external force, so that the wall panel connecting member 10 can be displaced along the first direction under the action of external force, thereby achieving the adjustment of the error.

[0102] like Figure 5 As shown, the connecting protrusion 12 is cylindrical, and the cross-sectional shape of the first recess 311 and the second recess 321 are both arc-shaped, less than half a circle, with the arc length corresponding to the first recess 311 being greater than the arc length corresponding to the second recess 321. When the movable pressing member 32 is in the pressing position, the support member 31 and the main body 13 are in contact, with a gap between the movable pressing member 32 and the main body 13.

[0103] It can be understood that the connecting protrusion 12 has a larger contact area with the first recess 311 and the second recess 321 so as to obtain a greater clamping force, and when the movable clamping member 32 is in the clamping position, the main body 13 will not block the movable clamping member 32, so that the movable clamping member 32 can better apply a clamping force to the connecting protrusion 12, so as to apply a greater clamping force, thereby further ensuring the reliability of the wall panel 100b after installation.

[0104] like Figure 4 As shown, the fastening assembly 30 further includes a plurality of locking members 33, which are used to position the movable pressing member 32 in a pressing position or a releasing position. One end of the locking member 33 movably passes through the support member 31 and is threadedly connected to the wall panel connector 10. The other end slides through the movable pressing member 32 and is provided with an abutment protrusion 331 that abuts the outer surface of the movable pressing member 32. The support member 31 is provided with an escape portion 312 for evading the locking members 33, thereby allowing the support member 31 to move relative to the wall panel connector 10 in a first direction.

[0105] It can be understood that when the locking member 33 rotates, the abutment protrusion 331 can gradually apply pressure to the movable pressing member 32 or gradually remove the pressure, thereby adjusting the distance between the movable pressing member 32 and the supporting member 31, and then the movable pressing member 32 can be placed in a clamping position or a release position, while the locking member 33 will not interfere with the movement of the supporting member 31, thereby ensuring that the wall connector can be displaced along the first direction.

[0106] In this embodiment, the locking member 33 is a screw, the head of which constitutes abutment protrusions 331 , of which there are four, arranged in groups of two on both sides of the movable pressing member 32 , and the two locking members 33 in the same group are located radially outside the connecting protrusion 12 .

[0107] Of course, in other embodiments, the locking member 33 may also be a bolt. When the locking member 33 is a bolt, the head of the bolt abuts against the outer surface of the movable pressing member 32, the nut of the bolt abuts against the wall panel connector 10, and the screw of the bolt sequentially passes through the movable pressing member 32, the support member 31, and the wall panel connector 10. In addition, the number of locking members 33 may be four or more.

[0108] Figure 7 is a schematic diagram of the three-dimensional structure of the wall panel connector and the partial engagement structure in an embodiment of the present invention; Figure 8 It is a schematic diagram of the three-dimensional structure of the support member and the partial engagement structure in an embodiment of the present invention.

[0109] like Figures 7 and 8As shown, the connection and fixing structure 100c also includes an engaging structure 50, which is used to achieve a fixed connection between the wall panel connector 10 and the support member 31 in the first direction, and includes an engaging protrusion 51 and an engaging recess 52. The engaging protrusion 51 is provided on the outer surface of the first portion 121 of the connecting protrusion 12. The engaging recess 52 is provided on the inner surface of the first recess 311. The outer shape of the engaging protrusion 51 is adapted to the inner shape of the engaging recess 52. When the movable pressing member 32 is in the pressing position or the releasing position, the engaging protrusion 51 is engaged with the engaging recess 52.

[0110] It can be understood that the engagement between the engaging protrusion 51 and the engaging recess 52 can realize the fixed connection between the connecting protrusion 12 and the supporting member 31 in the first direction, thereby realizing the fixed connection between the wall panel connecting member 10 and the supporting member 31 in the first direction, and then when the supporting member 31 moves along the first direction, it can drive the wall panel connecting member 10 to move synchronously, so that when the position of the supporting member 31 relative to the steel beam connecting member 20 is adjusted along the first direction by the adjusting component 40, the position of the wall panel connecting member 10 relative to the steel beam connecting member 20 can be adjusted along the first direction at the same time, so as to realize The error is now adjusted. In addition, when the support member 31 is limited to move relative to the steel beam connector 20 along the first direction, the wall panel connector 10 can be limited to move relative to the steel beam connector 20 along the first direction at the same time, so that the clamping assembly and the adjustment assembly 40 can cooperate to achieve the locking of the wall panel connector 10 in the first direction. In addition, the connection protrusion 12 can be limited to rotate relative to the support member 31, thereby limiting the wall panel connector 10 from shaking in the gap between the movable clamping member 32 and the main body 13, thereby preventing the installed wall panel 100b from shaking.

[0111] like Figures 7 and 8 As shown, the engaging protrusion 51 is partially annular, less than half a circle. The inner ring of the engaging protrusion 51 is in contact with the outer surface of the first portion 121 of the connecting protrusion 12. The arc length corresponding to the inner ring of the engaging protrusion 51 is greater than or equal to the arc length corresponding to the outer ring of the engaging protrusion 51, ensuring that the engaging protrusion 51 can be snapped into the engaging recess 52. There are multiple engaging protrusions 51, spaced apart along the extension direction of the connecting protrusion 12, with the engaging recesses 52 corresponding one to each engaging protrusion 51. The engaging protrusions 51 are integrally formed with the connecting protrusion 12.

[0112] Figure 9 It is a schematic diagram of the three-dimensional structure of the steel beam connecting member in an embodiment of the present invention.

[0113] like Figures 8 and 9As shown, two spaced-apart movable portions 313 are provided on the surface of the support member 31 facing away from the movable pressing member 32, and the movable portion 313 extends toward the side away from the movable pressing member 32 and perpendicular to the first direction. There are two steel beam connectors 20, which correspond one to one with the two movable portions 313. The steel beam connector 20 includes a steel beam connector 21 and two support portions 22. The steel beam connector 21 is provided at the bottom end of the steel beam connector 20 for connecting to the steel beam 100a. The two support portions 22 are spaced-apart on the steel beam connector 21 and extend perpendicularly thereto, and a movable space 24 is formed therebetween for the movable portion 313 to move along the first direction. The movable portion 313 extends into the corresponding movable space 24 and fits in contact with the steel beam connector 21. The adjustment assembly 40 is used to drive the movable portion 313 to move along the first direction.

[0114] It can be understood that the adjusting component 40 can drive the moving part 313 to move along the first direction in the moving space 24, so that the wall connecting part can be driven to move along the first direction through the supporting part 31, thereby adjusting the position of the supporting part 31 relative to the steel beam connecting part 20 along the first direction when the movable pressing part 32 is in the release position, thereby realizing the adjustment of the error. The other two supporting parts 22 can play the role of limiting the moving part 313, thereby limiting the distance of the error adjustment.

[0115] In this embodiment, the connection method between the steel beam connection portion 21 and the steel beam 100a can be welding, threaded connection, etc.

[0116] In this embodiment, the supporting member 31 is a plate, and the moving portion 313 and the supporting member 31 are integrally formed.

[0117] like Figure 9 As shown, the steel beam connector 20 also includes a locking connection portion 23, which is arranged on the support portion 22 and extends along the first direction. The number of the locking connection portions 23 is consistent with the number of the locking members 33. One end of the locking member 33 passes through the corresponding locking connection portion 23 and is threadedly connected thereto, thereby realizing the connection and fixation between the movable pressing member 32 and the steel beam connector 20.

[0118] In this embodiment, the steel beam connecting portion 21 , the two supporting portions 22 and the locking connecting portion 23 are integrally formed, and all three are plate members.

[0119] Figure 10 is a schematic diagram of the three-dimensional structure of a portion of the adjustment component in an embodiment of the present invention; Figure 11 It is a schematic diagram of the three-dimensional structure of another part of the adjustment component in an embodiment of the present invention.

[0120] like Figures 10 and 11As shown, the adjustment assembly 40 includes an adjustment drive member 41 and an adjustment guide member 42. The adjustment drive member 41 is arranged on one of the steel beam connectors 20 and extends along the first direction. The adjustment drive member 41 passes through the corresponding movable portion 313 and is threadedly connected thereto, and its two ends in the extension direction are rotatably connected to the corresponding two support portions 22 respectively. The first end of the adjustment drive member 41 in the extension direction passes through a corresponding support portion 22 and is formed with an adjustment operating portion 411 for driving it to rotate. The adjustment guide member 42 is arranged on the other steel beam connector 20 and extends along the first direction. The adjustment guide member 42 slides through the corresponding movable portion 313, and its two ends in the extension direction are fixedly connected to the corresponding two support portions 22 respectively.

[0121] It can be understood that the adjusting operating part 411 can be used to drive the adjusting driving member 41 to rotate, and when the adjusting driving member 41 rotates, the corresponding moving part 313 can be driven to move along the first direction. During the displacement of the moving part 313, the adjusting guide member 42 can play a guiding role, so that the wall connecting member can be driven to move along the first direction through the supporting member 31, thereby adjusting the position of the supporting member 31 relative to the steel beam connecting member 20 along the first direction when the movable pressing member 32 is in the release position. In addition, by adjusting the threaded connection between the driving member 41 and the moving part 313, the displacement of the supporting member 31 relative to the steel beam connecting member 20 along the first direction under the action of external force can be limited when the adjusting driving member 41 does not rotate.

[0122] In this embodiment, the adjustment drive member 41 and the adjustment guide member 42 are both rods. The adjustment drive member 41 is a screw having only a partial thread located in the middle of the screw, which is used to connect with the moving part 313, and the head of the screw constitutes the adjustment operating part 411.

[0123] In this embodiment, both ends of the adjusting driving member 41 in the extension direction are rotatably connected to the corresponding two supporting parts 22 through bearings.

[0124] like Figure 11 As shown, the second end of the adjustment driver 41 extends through a corresponding support portion 22. The adjustment assembly 40 also includes a stopper 43, which is sleeved over the second end of the adjustment driver 41 and threadedly connected thereto. The stopper 43 slidably engages with the surface of the corresponding support portion 22. The adjustment operating portion 411 has a larger cross-sectional dimension than the adjustment driver 41 and slidably engages with the surface of the corresponding support portion 22.

[0125] It can be understood that the cooperation between the limit member 43 and the adjustment operating part 411 can further strengthen the limiting fixation of the adjustment drive member 41 in the first direction, thereby further strengthening the limiting effect on the support member 31, thereby further ensuring the reliability of the wall panel 100b after installation, and will not affect the normal rotation of the adjustment drive member 41, and can also facilitate the installation of the adjustment drive member 41 to the steel beam connector 20.

[0126] In this embodiment, the limiting member 43 is a sleeve member.

[0127] like Figure 9 As shown, the extended end of one of the support parts 22 in the steel beam connector 20 is in contact with the surface of the support member 31 facing away from the movable pressing member 32. The contour of the extended end of the support part 22 is adapted to the contour of the surface of the support member 31.

[0128] It can be understood that the support portion 22 can play a guiding role when the support member 31 is displaced along the first direction, thereby ensuring the stability of the wall connector during displacement and further ensuring the accuracy of error adjustment.

[0129] The process of installing the wall panel 100b by using the connecting and fixing structure 100c in this embodiment is as follows:

[0130] First, connect the wall panel connector 10 to the keel structure in the wall panel 100b, and connect the steel beam connector 20 to the steel beam 100a, and then install the support member 31 on the steel beam connector 20 through the adjustment assembly 40;

[0131] Then, the wall panel 100b is lifted, and the connecting protrusion 12 of the wall panel connector 10 is aligned with the supporting member 31. Then, the movable pressing member 32 is installed on the steel beam connector 20 through the fastening assembly 30. At this time, the locking member 33 in the fastening assembly 30 is not fixed, so that the wall panel connector 10 and the steel beam connector 20 are connected as a whole. The preliminary installation of the wall panel 100b is completed.

[0132] After the wall panel 10 is initially installed, the adjustment assembly 40 is used to adjust the wall panel 100b to eliminate the construction error in the first direction, so that the wall panel 100b is accurately installed in the set position. After the adjustment is completed, the locking member 33 in the fastening assembly 30 is fixed to complete the installation of the wall panel 100b.

[0133] This installation method only requires prefabrication of each component, and then transportation to the construction site, and assembly and installation on site through connection. It can achieve green assembly and has the advantages of energy saving and environmental protection.

[0134] Functions and effects of the embodiment: According to the connection and fixing structure and green prefabricated building wall panels involved in this embodiment, the green prefabricated building wall panels include steel beams, wall panels and connection and fixing structures. The connection and fixing structure includes wall panel connectors, steel beam connectors, fastening components and adjustment components, including support members and movable pressing members. The movable pressing member has at least a clamping position that cooperates with the support member to clamp part of the wall panel connector between the two and a release position that allows the wall panel connector to be displaced along a first direction under the action of an external force. When the movable pressing member is in the clamping position or the release position, the wall panel connector and the support member form a fixed connection in the first direction. When the error needs to be adjusted, the movable pressing member is first placed in the release position, and then the position of the support member relative to the steel beam connector is adjusted along the first direction through the adjustment component, so that the wall panel connector can be adjusted along the first direction. Relative to the position of the steel beam connector, the position of the wall panel relative to the steel beam can be adjusted along the first direction, thereby realizing the adjustment of the error. After the adjustment, the movable pressing member is placed in the pressing position. At this position, the part of the wall panel connector is pressed between the two by the cooperation between the movable pressing member and the support member, thereby fixing the wall panel connector between the movable pressing member and the support member, thereby limiting the displacement of the wall panel connector relative to the steel beam connector along the first direction, thereby fixing the wall panel connector on the steel beam connector, and at the same time, limiting the displacement of the support member relative to the steel beam connector along the first direction through the adjustment component, thereby limiting the displacement of the wall panel connector relative to the steel beam connector along the first direction, thereby realizing the locking of the wall panel connector in the first direction through the cooperation of the pressing component and the adjustment component, thereby ensuring the reliability of the wall panel after installation.

[0135] Furthermore, according to the connection and fixing structure involved in this embodiment and the green prefabricated building wall panel assembly, the wall panel connecting piece is first connected to the keel structure in the wall panel, and the steel beam connecting piece is connected to the steel beam, and then the support piece is installed on the steel beam connecting piece through the adjustment component; then the wall panel is lifted so that the connection protrusion of the wall panel connecting piece is aligned with the support piece, and then the movable pressing piece is installed on the steel beam connecting piece through the fastening component. At this time, the locking piece in the fastening component is not fixed, so that the wall panel connecting piece and the steel beam connecting piece are connected as one, and the preliminary installation of the wall panel is completed; after the preliminary installation of the wall panel is completed, it is adjusted through the adjustment component to eliminate the construction error of the wall panel in the first direction, so that the wall panel is accurately installed in the set position, and after the adjustment is completed, the locking piece in the fastening component is fixed to complete the installation of the wall panel; this installation method only requires prefabrication of each component, and then transportation to the construction site, and assembly and installation on site through the connection method, which can achieve green assembly and has the advantages of energy saving and environmental protection.

[0136] The above embodiments are only preferred embodiments of the present technical solution and are not intended to limit the protection scope of the present technical solution. Therefore, any equivalent changes made based on the structure, shape, and principle of the present technical solution should be included in the protection scope of the present technical solution.
