Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and more particularly to a prefabricated wall connection structure that can be quickly assembled. Background Art

[0002] Prefabricated walls, defined as building wall components prefabricated in a factory, are a crucial component of prefabricated construction. They undergo processes such as rebar binding, concrete pouring, and curing in the factory before being transported to the construction site for installation. This significantly improves construction efficiency, ensures component quality, and reduces on-site pollution.

[0003] However, during the construction of existing prefabricated walls, vertical steel bars are usually embedded in the foundation. The spacing between the steel bars corresponds to the position of the reserved holes at the bottom of the prefabricated wall. The prefabricated wall is then lifted by a lifting device, and the reserved holes at the bottom of the wall are inserted into the embedded vertical steel bars. During the insertion process, the position of the wall needs to be adjusted manually until it is completely aligned. Finally, grouting material is injected into the connection to form a fixed connection. This assembly process requires a lot of manpower for positioning and adjustment, resulting in a cumbersome assembly process. In addition, when the connection structure is subjected to horizontal and vertical loads, the load transfer path is single, and stress concentration is prone to occur, resulting in premature damage to the connection part and insufficient connection strength.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention only requires that the embedded parts be fixed in the foundation in advance and grouting material be pre-injected into the steel bar groove. Then, the wall is lifted and dropped to the top of the embedded parts by a lifting device, so that the guide plug is inserted into the guide slot of the embedded part. The guide plug is guided in the vertical direction by the guide slot, so that the falling trajectory of the wall is fixed. Further, multiple longitudinal steel bars at the bottom of the wall can be automatically inserted into the corresponding steel bar grooves respectively, and the longitudinal steel bars are rigidly anchored after the grouting material in the steel bar groove solidifies. At the same time, during the process of the guide plug being inserted into the guide slot, the first oblique reinforcement and the second oblique reinforcement of the three-way reinforcement assembly inside it can be rotated in the vertical direction to form a cross-shaped reinforcement, and cooperate with the fixed reinforcement to form a trident-shaped structure. Finally, by injecting grouting material into the embedded part, the trident-shaped structure of the three-way reinforcement assembly is fully combined with the grouting material, and the wall, the guide plug and the embedded part are firmly connected as one, completing the rapid assembly of the prefabricated wall. The operation process is simple and the connection strength is high, which solves the problems of complicated assembly process and insufficient connection strength of the existing prefabricated wall.

[0017] 2. During the process of inserting the guide plug into the guide slot of the present invention, the first oblique reinforcement and the second oblique reinforcement of the three-way reinforcement assembly can be rotated to a cross state and respectively screwed into the corresponding oblique grooves. After the grouting is cured, the grouting material fills the gap between the oblique grooves and the oblique reinforcement to form a fixed connection. The horizontal load borne by the wall is transmitted to the side wall of the embedded part through the oblique reinforcement, and then to the foundation. The vertical load borne by the wall is transmitted to the bottom of the embedded part through the fixed reinforcement and the longitudinal reinforcement, and then to the foundation. The horizontal load force is offset by the oblique component of the oblique reinforcement, and the vertical load is transmitted synergistically through the fixed reinforcement and the longitudinal reinforcement, avoiding overload of a single component, forming a multi-path load dispersion system, making the load transmission more uniform, and effectively reducing the risk of structural damage caused by stress concentration, and finally achieving a comprehensive improvement in the pull-out, shear and compressive performance, meeting the safety requirements of the prefabricated wall under complex load conditions.

[0018] 3. The present invention forms an inclined surface structure on the side wall of the guide block from a vertical surface structure downward, making it easier to insert the guide block into the guide slot. During the insertion process, the inclined surface 1 can guide the guide block to align with the guide slot for insertion, automatically correcting the horizontal position deviation of the wall. The first vertical surface guides the guide block into a vertical descent stage, limiting its horizontal shaking, ensuring that the longitudinal steel bars are vertically aligned with the steel bar groove, until the inclined surface structure of the guide block side wall fits on the inclined surface 2 to complete the plug-in assembly, making the plug-in process accurate and fast, without the need for manual intervention, and greatly improving the assembly speed of the prefabricated wall.

[0019] 4. When the guide plug of the present invention is inserted into the guide slot, the bottom guide gear rotates and moves downward on the tooth mouth, driving the double-sided tooth plates and the control plate to slide downward, and the single-sided tooth plate on the top of the control plate drives the first rotating tooth and the second rotating tooth to rotate, so that the first oblique rib and the second oblique rib rotate crosswise and embed into the oblique slot, and the limit block locks the reverse rotation of the guide gear, so that the first oblique rib and the second oblique rib can stably maintain a cross structure and are unlikely to rotate. As a result, the first oblique rib and the second oblique rib can automatically form a cross structure and lock in the guide slot during the falling process of the wall, without manual operation or additional energy, and have the advantages of simple assembly and high connection stability.

[0020] 5. In the process of inserting the guide plug into the guide slot of the present invention, the two-sided tooth plates move downward at the same time, and the locking plates are gradually inserted into the triangular grooves at the bottom of the two-sided tooth plates. The locking strips of the locking plates are gradually squeezed into the grooves on the inner side walls of the triangular grooves, forming a stepped bite, so that the guide plug and the embedded parts form a mechanical locking connection, which strengthens the connection firmness between the guide plug and the embedded parts and improves the pull-out resistance of the wall. The first oblique reinforcement and the second oblique reinforcement are respectively embedded in the oblique grooves to form a cross structure, thereby realizing a multi-point and multi-directional skeleton structure of the guide plug and the embedded parts. After the guide slots and grooves are filled with grouting material and solidified, a rigid whole with high connection strength is formed. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] like Figures 1 to 16 As shown, the present invention relates to a prefabricated wall connection structure that can be assembled quickly, including a wall 1, a guide plug 2 is connected to the bottom of the wall 1, and an embedded part 3 is arranged below the guide plug 2.

[0044] In an embodiment of the present invention, a plurality of longitudinal steel bars 101 are also connected to the bottom of the wall 1; a plurality of steel bar grooves 301 are provided on the top surface of the embedded part 3. When the wall 1 is assembled on the top of the embedded part 3, the plurality of longitudinal steel bars 101 are respectively inserted into the corresponding steel bar grooves 301 to fix the wall 1; a guide slot 302 is provided on the top surface of the embedded part 3; the guide plug 2 is used to be inserted into the guide slot 302, forming a vertical guiding effect on the wall 1 in the process of descending to the top of the embedded part 3, so that the longitudinal steel bars 101 are accurately inserted into the steel bar groove 301; wherein, a plurality of three-way bar assemblies 4 are arranged inside the guide plug 2, and the three-way bar assembly 4 includes a fixed bar 401, a first oblique bar 402 and a second oblique bar 403. The fixed bar 401 is a steel bar fixedly arranged in the vertical direction, and the first oblique bar 402 and the second oblique bar 403 can be rotated from the vertical direction to form a cross-shaped steel bar. The present invention only requires that the embedded parts 3 be fixed in the foundation in advance by cement mortar, and grouting material be pre-injected into the steel bar groove 301, and then the wall 1 is lifted and dropped on the top of the embedded parts 3 by the lifting equipment, so that the guide plug 2 is inserted into the guide slot 302 of the embedded part 3, and the guide plug 2 is guided in the vertical direction by the guide slot 302, so that the falling trajectory of the wall 1 is fixed, and further, the multiple longitudinal steel bars 101 at the bottom of the wall 1 can be automatically inserted into the corresponding steel bar groove 301 respectively, and the grouting material in the steel bar groove 301 forms a rigidity on the longitudinal steel bars 101 after solidification. During the process of the guide plug 2 being inserted into the guide slot 302, the first oblique reinforcement 402 and the second oblique reinforcement 403 of the three-way reinforcement assembly 4 inside it can be rotated in the vertical direction to form a cross-shaped reinforcement, and cooperate with the fixed reinforcement 401 to form a trident-shaped structure. Finally, by injecting grouting material into the embedded part 3, the trident-shaped structure of the three-way reinforcement assembly 4 is fully combined with the grouting material, and the wall 1, the guide plug 2 and the embedded part 3 are firmly connected as one, completing the rapid assembly of the prefabricated wall. The operation process is simple and the connection strength is high, which solves the problem of the cumbersome assembly process and insufficient connection strength of the existing prefabricated wall.

[0045] In an embodiment of the present invention, a plurality of straight steel bars 303 are connected to the bottom of the embedded part 3. The plurality of straight steel bars 303 are inserted into the foundation and connected by grouting material, which can enhance the connection firmness between the embedded part 3 and the foundation. A grouting hole 304 is provided at the top of the embedded part 3. The output end of the grouting hole 304 is connected to the guide slot 302. When the wall 1 is assembled on the top of the embedded part 3, the grouting material is injected into the grouting hole 304 to fill the guide slot 302, thereby realizing a firm connection between the guide plug 2 and the embedded part 3.

[0046] In an embodiment of the present invention, a slope 1 3021 is provided at the slot of the guide slot 302, a first vertical surface 3022 is provided below the slope 1 3021, a second vertical surface 3023 is provided below the first vertical surface 3022, and a second vertical surface 3024 is provided below the slope 2 3023; a slope 305 is provided on the slope 2 3023 of the inner side wall of the guide slot 302, the slope 305 extends to the second vertical surface 3024, and a plurality of teeth 306 are arranged on the second vertical surface 3024; the same structural components are arranged on the other inner side wall of the guide slot 302, and the slope 305 on the inner side wall of the guide slot 302 is staggered with the slope 305 on the other inner side wall of the guide slot 302. During the process of inserting the guide plug 2 into the guide slot 302, the first oblique reinforcement 402 and the second oblique reinforcement 403 of the three-way reinforcement assembly 4 can be rotated to a cross state and respectively screwed into the corresponding oblique groove 305. After the grouting is cured, the grouting material fills the gap between the oblique groove 305 and the oblique reinforcement to form a fixed connection. The horizontal load borne by the wall 1 is transmitted to the side wall of the embedded part 3 through the oblique reinforcement, and then to the foundation. The vertical load borne by the wall 1 is transmitted to the bottom of the embedded part 3 through the fixed reinforcement 401 and the longitudinal reinforcement 101, and then to the foundation. The horizontal load force is partially offset by the oblique component of the oblique reinforcement, and the vertical load is transmitted in coordination through the fixed reinforcement 401 and the longitudinal reinforcement 101, avoiding overload of a single component, forming a multi-path load dispersion system, making the load transmission more uniform, effectively reducing the risk of structural damage caused by stress concentration, and ultimately achieving a comprehensive improvement in the pull-out, shear and compressive performance, meeting the safety requirements of the prefabricated wall under complex load conditions.

[0047] It is worth noting that the side wall of the guide plug 2 is set to a vertical surface structure, and the bottom of the vertical surface structure is arranged as an inclined surface structure. By forming the side wall of the guide plug 2 from the vertical surface structure to a downward inclined surface structure, the guide plug 2 is easier to insert into the guide slot 302. During the insertion process, the inclined surface 1 3021 can guide the guide plug 2 to align with the guide slot 302 for insertion, automatically correcting the horizontal position deviation of the wall 1. The first vertical surface 3022 guides the guide plug 2 into the vertical descent stage, limiting its horizontal shaking, ensuring that the longitudinal steel bar 101 is vertically aligned with the steel bar groove 301, until the inclined surface structure of the side wall of the guide plug 2 fits on the inclined surface 2 3023, completing the plug-in assembly, making the plug-in process accurate and fast, without the need for manual intervention, and greatly improving the assembly speed of the prefabricated wall.

[0048] As another embodiment of the present invention, a plurality of guide blocks 201 are integrally formed at the bottom of the guide plug 2, a plurality of guide gears 202 are rotatably arranged on the lower side wall of the guide block 201, a guide gear 202 of the same structure is arranged on the other lower side wall of the guide block 201, a plurality of grooves 203 are provided at the bottom of the guide plug 2, the notches of the grooves 203 are arranged between every two guide blocks 201, and the plurality of grooves 203 are connected through connecting grooves 204, a slurry discharge groove 205 is provided on the side wall of one of the grooves 203, and a plurality of slide rails 206 are arranged on the inner side wall of the groove 203; a slurry discharge port 102 is provided on the side wall of the wall 1, and the output end of the slurry discharge groove 205 is connected to the slurry discharge port 102. In the present invention, after the wall 1 is assembled on the top of the embedded part 3, grouting material is injected into the grouting hole 304. After the grouting material fills the guide slot 302, it enters the groove 203 and evenly fills multiple grooves 203 through the connecting groove 204 until it overflows from the grouting groove 205 and is discharged from the grouting port 102. Then the grouting operation can be stopped.

[0049] It is worth noting that a convex groove is provided on the lower side wall of the guide block 201, and a limit block 207 is rotatably arranged in the convex groove. The side wall of the limit block 207 is set as a toothed protrusion, and the toothed protrusion of the limit block 207 is meshed and connected with the guide gear 202. The top of the limit block 207 is connected to the inner side wall of the convex groove through a spring 208; wherein, the bottom of the inner cavity of the convex groove is a hollow structure and the top is a flat structure. The hollow structure at the bottom of the inner cavity of the convex groove is used to provide space for the limit block 207 to rotate downward, and the flat structure at the top of the inner cavity of the convex groove is used to limit the limit of the upward rotation of the limit block 207. When the guide plug 2 is inserted into the guide slot 302, the guide gear 202 on the lower side wall of the guide block 201 contacts and meshes with the tooth opening 306 on the inner side wall of the guide slot 302. As the guide plug 2 continues to descend, the guide gear 202 rotates and moves downward on the tooth opening 306. When the guide gear 202 rotates, it can drive the limit block 207 to rotate downward in the convex groove through the toothed protrusion. The hollow structure at the bottom of the convex groove provides it with rotation space. At the same time, the spring 208 is stretched. When the guide plug 2 stops descending, the spring 208 resets and pulls the limit block 207 to rotate, so that the toothed protrusion of the limit block 207 is tightly meshed with the guide gear 202. Since the upward rotation of the limit block 207 is restricted by the top plane of the convex groove, the reverse rotation of the guide gear 202 is locked, so that the guide gear 202 only has a one-way rotation function.

[0050] In an embodiment of the present invention, the three-way rib assembly 4 also includes a fixed column 404 connected to the inner wall of the groove 203, and the fixed rib 401 passes through the side wall of the fixed column 404. The fixed rib 401 also passes through the top of the guide plug 2 and extends to the inside of the wall 1 to strengthen the connection strength between the wall 1 and the guide plug 2. The first rotating tooth 405 and the second rotating tooth 406 are rotatably arranged on the outer wall of the fixed column 404; one end of the first oblique rib 402 is connected to the side wall of the first rotating tooth 405, and the side wall of the first rotating tooth 405 is also connected to another first oblique rib 402; one end of the second oblique rib 403 is connected to the side wall of the second rotating tooth 406, and the side wall of the second rotating tooth 406 is also connected to another second oblique rib 403.

[0051] As another embodiment of the present invention, the three-way rib assembly 4 also includes multiple control plates 407, and the side walls of the control plates 407 are provided with sliding grooves, and the control plates 407 are slidingly connected to the sliding rails 206 of the grooves 203 through the sliding grooves; a single-sided tooth plate 408 is integrally formed on the top of the control plate 407, and the single-sided tooth plates 408 on the tops of the two control plates 407 are staggered, and the single-sided tooth plate 408 on the top of one control plate 407 is meshed and connected with the first rotating tooth 405, and the single-sided tooth plate 408 on the top of the other control plate 407 is meshed and connected with the second rotating tooth 406; it is worth noting that a double-sided tooth plate 409 is integrally formed on the bottom of the control plate 407, and one side of the double-sided tooth plate 409 is meshed and connected with the guide gear 202, and the other side is meshed and connected with the other guide gear 202.

[0052] The fixed column 404 in the three-way rib assembly 4 of the present invention serves as a supporting core, and the fixed rib 401 passing through its side wall is vertically anchored between the wall 1 and the guide plug 2 to form a vertical connection skeleton. When the guide plug 2 is inserted into the guide slot 302, the guide gear 202 at its bottom rotates and moves downward on the tooth opening 306 on the inner wall of the guide slot 302, thereby driving the double-sided tooth plates 409 engaged with it to descend, so that the control plate 407 slides downward along the slide rail 206. The single-sided tooth plates 408 on the top of the two control plates 407 are staggered. The single-sided tooth plates 408 engaged with the first rotating teeth 405 drive them to rotate forward, so that the first oblique rib 402 rotates outward from a vertical state and engages with the second rotating teeth 406. The engaged single-sided tooth plate 408 drives it to rotate in the opposite direction, causing the second oblique rib 403 to rotate outward from a vertical state and expand. Finally, the first oblique rib 402 and the second oblique rib 403 form a cross shape inside the guide plug block 2 and are respectively embedded in the oblique groove 305 on the inner wall of the guide slot 302. The limit block 207 is used to lock the reverse rotation of the guide gear 202, so that the first oblique rib 402 and the second oblique rib 403 can stably maintain the cross structure and are unlikely to rotate. During the falling process of the wall 1, the first oblique rib 402 and the second oblique rib 403 can automatically form a cross structure and lock in the guide slot 302 without manual operation or additional energy. It has the advantages of simple assembly and high connection stability.

[0053] In an embodiment of the present invention, a plurality of locking plates 307 are arranged at the bottom of the guide slot 302, the side walls of the locking plates 307 are inclined structures, and a plurality of clips 308 are arranged at the upper end of the side walls of the locking plates 307; a triangular groove 410 is provided at the bottom of the double-sided tooth plate 409, and a plurality of clips 411 are provided on the inner side wall of the triangular groove 410, and the locking plate 307 is plugged into and matched with the triangular groove 410. During the process of inserting the guide plug 2 into the guide slot 302, the bilateral tooth plates 409 move downward at the same time, and the locking plate 307 is gradually inserted into the triangular groove 410 at the bottom of the bilateral tooth plates 409. The card strip 308 of the locking plate 307 is gradually squeezed into the card groove 411 on the inner wall of the triangular groove 410, forming a stepped bite, so that the guide plug 2 and the embedded part 3 form a mechanical locking connection, strengthening the connection firmness of the guide plug 2 and the embedded part 3, and improving the pull-out resistance of the wall 1. The first oblique reinforcement 402 and the second oblique reinforcement 403 are respectively embedded in the oblique groove 305 to form a cross structure, realizing a multi-point and multi-directional skeleton structure of the guide plug 2 and the embedded part 3. After the grouting material fills the guide slot 302 and the groove 203 and solidifies, a rigid whole with high connection strength is formed.

[0054] Working principle: This embodiment provides a prefabricated wall connection structure that can be assembled quickly. When in use, the embedded parts 3 are first fixed to the foundation with cement mortar, and grouting material is pre-injected into the steel bar groove 301. The wall 1 is lifted by using a lifting device, and the guide plug 2 is aligned with the guide slot 302 and falls. The inclined surface structure of the side wall of the guide plug 2 cooperates with the inclined surface 1 3021 and the inclined surface 2 3023 of the guide slot 302 to automatically correct the horizontal deviation and guide the vertical descent, ensuring that the longitudinal steel bar 101 is accurately inserted into the steel bar groove 301, and rigid anchoring is achieved through the grouting material solidified in the steel bar groove 301; during the insertion process of the guide plug 2, the bottom guide gear 202 rotates and moves downward along the tooth mouth 306 of the inner wall of the guide slot 302, driving the double-sided tooth plates 409 to descend, so that the control plate 407 slides downward along the slide rail 206, and the single The side tooth plates 408 are arranged in an interlaced manner. The single-sided tooth plate 408 engaged with the first rotating tooth 405 drives it to rotate forward, causing the first oblique rib 402 to rotate outward and expand from a vertical state. The single-sided tooth plate 408 engaged with the second rotating tooth 406 drives it to rotate in the opposite direction, causing the second oblique rib 403 to rotate outward and expand from a vertical state. Finally, the first oblique rib 402 and the second oblique rib 403 form a cross shape inside the guide plug block 2 and are respectively embedded in the oblique groove 305 of the inner wall of the guide slot 302. At the same time, the card strip 308 of the locking plate 307 is inserted into the triangular groove 410 at the bottom of the double-sided tooth plate 409, forming a stepped bite with the card groove 411. Finally, grouting material is injected into the grouting hole 304 to fill the guide slot 302, the groove 203 and all gaps. The grouting operation is stopped after being discharged through the grouting groove 205 and the grouting port 102, thereby completing the rapid assembly of the prefabricated wall.
