Technical Field

[0001] The present invention relates to the technical field of engineering structures, and in particular to an assembled building prefabricated component and a component assembly method. Background Art

[0002] For example, the publication number is CN113216510A, and the name is a grouting sleeve connected with an ECC tube for prefabricated concrete components, which includes a prefabricated RC concrete component A, a prefabricated ECC tube, and a prefabricated RC concrete component B. The prefabricated RC concrete component A is a variable cross-section, and the plastic hinge end portion is an embedded tenon-type section adapted to the prefabricated ECC tube, and the embedded tenon is used to insert into the prefabricated ECC tube. The connection between the prefabricated RC concrete component A and the prefabricated RC concrete component B is achieved by a grouting sleeve pre-buried in the prefabricated ECC tube, and the prefabricated joints between the three are connected by grouting sleeves and joint materials such as high-strength structural adhesives, UHPC, and high-strength grouting materials.

[0011] Among them, the connection mechanism includes a support pipe, a plurality of slurry outlet holes distributed in an annular array are formed on the outer surface of the support pipe, installation ring frames are sleeved on both sides of the outer surface of the support pipe, a plurality of rib strips distributed in an annular array are arranged between the two installation ring frames, a support frame is arranged on one side of the inner wall of the support pipe, a through pipe is arranged inside the support frame, external connecting sleeves are arranged inside the two installation ring frames, a wire mesh cover sleeved on the outer surface of the rib strips is arranged between the two external connecting sleeves, a plurality of round holes distributed in an annular array are formed on the outer surface of the wire mesh cover, steel wire strips are arranged inside the plurality of round holes, one end of the support pipe is fixedly connected with the slurry through pipe, and the other end of the support pipe is fixedly connected with the feed pipe.

[0012] Among them, the plugging mechanism includes a support ring, a plurality of sealing pieces distributed in an annular array are arranged on the inner wall of the support ring, and the support ring is arranged inside the slurry through pipe and the slurry outlet pipe.

[0014] A component assembly method for precast components of an assembled building, and the specific assembly method is as follows:

[0015] Step 1: During assembly, dock the connecting mechanism with the two grouting pipe fittings. Then insert the steel bars of the precast wall into the pipe jacking mechanism so that the steel bars extend into the interior of the grouting pipe fittings. Next, install the connecting mechanism at the bottom of the grouting pipe fittings. Finally, use a mold to pour cement for the pipe jacking mechanism, grouting pipe fittings, connecting mechanism, and connecting structure.

[0016] Step 2: The poured cement is only poured on the outer surfaces of the grouting pipe fittings, pipe jacking mechanism, through pipe, connecting mechanism, and connecting structure. To prevent cement from entering the interior of the grouting pipe fittings, use a plugging mechanism to plug the feed hole of one of the grouting pipe fittings buried inside the cement wall. During wall pouring, both grouting pipe fittings are located inside the wall, but the slurry outlet pipe and feed pipe of one of the grouting pipe fittings extend outside the wall, which facilitates pouring cement into the interiors of the grouting pipe fittings, connecting mechanism, and connecting structure during subsequent assembly of the precast wall.

[0017] In summary, the technical effects and advantages of the present invention are as follows:

[0018] 1. After the precast wall is fabricated and assembled onto the foundation, the precast wall casting steel bars protruding from the foundation in advance need to be inserted into the inner pipe within the precast wall. The inner pipe is a pipeline embedded in the precast wall and is used to guide the steel bars to the correct connection position. As the steel bars are inserted, they extend into the interior of the grouting pipe fittings and finally abut against the conical spring. The conical spring is a special spring device, and its shape design is as shown in the figure to generate a certain elastic force when the steel bars are inserted, thereby increasing the friction between the steel bars and the grouting pipe fittings. The special shape and elastic design of the conical spring enable it to provide a radial extrusion force when the steel bars are inserted, which helps to increase the contact area and friction between the steel bars and the grouting pipe fittings, thereby enhancing the stability of the steel bar connection. Through the action of the conical spring, the connection strength between the steel bars and the grouting pipe fittings is significantly enhanced, reducing the risk of connection failure caused by steel bar sliding or movement. The design of the conical spring increases the pouring strength at the steel bar connection and improves the safety performance of the entire prefabricated building structure. Especially when natural disasters such as earthquakes occur, it can better resist the impact of external forces.

[0019] 2. During the initial pouring process of the present invention, cement first adheres to the outer surfaces of the wire mesh cover and the steel wire strips. The wire mesh cover is made of microporous metal mesh. This design can effectively prevent a large amount of cement from directly entering the interior of the wire mesh cover. Instead, it allows the cement to form a coating on the outer surface. The wire mesh cover made of microporous metal mesh can, on the one hand, prevent a large amount of cement from entering the interior, and on the other hand, provide additional support force to enhance the adhesiveness of the cement. When cement is poured into the first installation pipe, the cement will enter the interior of the support pipe through the slurry pipe, ensuring that the cement can be evenly distributed throughout the connection mechanism. The design of the through pipe aims to increase the strength of the connection between the support pipe and the slurry pipe. After the cement enters the interior of the support pipe, it flows out through the slurry holes and fills the interior of the wire mesh cover, which helps to ensure the even distribution of the cement and increase the filling density inside the wire mesh cover, thereby enhancing the overall structural strength. The rib design is intended to support the shape of the wire mesh cover, making its cross-section wavy. This wavy design increases the structural strength after the cement is poured because the wavy surface provides more contact area, thus enhancing the adhesion between the cement and the structure.

[0020] 3. Through the designs of the wire mesh cover, the support pipe, and the ribs, the present invention increases the structural strength after the cement is poured, making the connection more firm and durable. The microporous design of the wire mesh cover effectively prevents a large amount of cement from entering the interior, thus avoiding the waste of cement and ensuring that a protective layer is formed on the outer surface. The design of the through pipe enhances the strength of the connection between the support pipe and the slurry pipe, further improving the overall stability of the connection mechanism. The ribs make the cross-section of the wire mesh cover wavy, increasing the contact area between the cement and the structure, thereby enhancing the adhesion performance of the cement and improving the tensile strength of the connection.

Detailed implementation mode

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] Embodiment 1. Refer to Figures 1 to 21 An assembled building precast member as shown, including two grouting pipe fittings 1. At the upper ends of both grouting pipe fittings 1, a top pipe mechanism 5 is provided. A through pipe 4 is jointly arranged between the two top pipe mechanisms 5. At the lower ends of both grouting pipe fittings 1, a connection mechanism 2 is provided. A connection mechanism 3 for increasing the building strength is jointly arranged between the two grouting pipe fittings 1. A strengthening mechanism 6 for increasing the steel bar connection strength is arranged inside both grouting pipe fittings 1. A plugging mechanism 7 is arranged inside both grouting pipe fittings 1;

[0046] It should be noted that during assembly, the connection mechanism 3 is butted with the two grouting pipe fittings 1, and then the steel bars of the precast wall are inserted into the top pipe mechanism 5 so that the steel bars extend into the interior of the grouting pipe fittings 1. Then, the connection mechanism 2 is installed at the bottom of the grouting pipe fittings 1. Finally, the top pipe mechanism 5, grouting pipe fittings 1, connection mechanism 2, and connection mechanism 3 are subjected to cement pouring using a mold;

[0047] The poured cement is only poured on the outer surfaces of the grouting pipe fitting 1, the pipe jacking mechanism 5, the through pipe 4, the connecting mechanism 3 and the connecting mechanism 2. In order to prevent the cement from entering the inside of the grouting pipe fitting 1, a plugging mechanism 7 is used to plug the feed hole of a grouting pipe fitting 1 buried inside the cement wall. Since both grouting pipe fittings 1 are located inside the wall during the pouring of the wall, but the slurry outlet pipe 11 and the feed pipe 13 of one of the grouting pipe fittings 1 extend to the outside of the wall, so as to facilitate the pouring of cement into the inside of the grouting pipe fitting 1, the connecting mechanism 3 and the connecting mechanism 2 during the subsequent assembly of the precast wall.

[0048] Among them, the docking of the connecting mechanism 3 and the grouting pipe fitting 1 is to ensure that the precast components can be accurately docked during the final assembly to form a solid whole. The steel bars in the precast wall are inserted into the pipe jacking mechanism 5 so that the steel bars can pass through the entire grouting pipe fitting 1 to enhance the structural strength of the connection part of the precast wall.

[0049] Embodiment 2: Based on the pipe jacking mechanism 5, the grouting pipe fitting 1, the strengthening mechanism 6 and the connecting mechanism 2 proposed in Embodiment 1, this embodiment provides a further technical solution for the pipe jacking mechanism 5, the grouting pipe fitting 1, the strengthening mechanism 6 and the connecting mechanism 2.

[0050] The pipe jacking mechanism 5 includes a cover 53. Inside the cover 53, there is a second installation pipe 51. A number of second through holes 52 are arranged on the outer surface of the second installation pipe 51 in an annular array. Rib rings 55 are provided on both the outer surface and the inner wall of the cover 53. A connecting pipe 54 is provided on the outer surface of the cover 53. A through pipe 4 is arranged inside the connecting pipe 54. The cover 53 is installed at the upper end of the first installation pipe 12.

[0051] It should be noted that during use, the second installation pipe 51 is inserted into the broken end of the steel bar for making the precast wall. As the steel bar extends out and enters the grouting pipe fitting 1, one end of the extended steel bar stops pushing the grouting pipe fitting 1 after touching the strengthening mechanism 6. When the precast wall is poured, the poured concrete will cover the surfaces of the cover 53 and the rib ring 55. Part of the concrete will enter the second installation pipe 51 through the second through holes 52 to fix the steel bar in the second installation pipe 51. The design of the rib ring 55 can make the cover 53 more firmly adsorbed in the precast wall body, and the design of the rib ring 55 can enhance the cement strength at the connection of the precast wall.

[0052] Among them, the second installation pipe 51 is inserted into the broken end of the steel bar of the precast wall to accurately position the steel bar in the grouting pipe fitting 1 and ensure the correct connection between the steel bar and the grouting pipe fitting. One end of the steel bar extends into the grouting pipe fitting 1 until it touches the strengthening mechanism 6. The function of the strengthening mechanism 6 is to provide additional support and fixing functions. When the precast wall is poured with concrete, the concrete will cover the surfaces of the cover 53 and the rib ring 55, and firmly fix the cover 53 and the rib ring 55 inside the precast wall.

[0053] Part of the concrete will enter the pipe through the second through-hole 52 on the second installation pipe 51. The main purpose of this is to enhance the bonding force between the steel bar and the second installation pipe 51, ensuring that the steel bar will not easily come out of the pipe. The design of the rib ring 55 can not only help the cover 53 to be more firmly "adsorbed" in the precast wall, but also improve the cement strength at the joint of the precast wall by increasing the contact area. The existence of the rib ring provides more friction.

[0054] Through the combination of the steel bar and the second installation pipe 51, together with the curing of the concrete, the stability of the connection part can be significantly improved, preventing the precast components from loosening during use. The design of the strengthening mechanism 6 and the rib ring 55 enhances the reliability of the connection, ensuring a firm connection between the steel bar and the precast component, and reducing possible future structural problems.

[0055] The connection mechanism 2 includes a bottom pipe 21 and an inner pipe 23. A number of T-shaped pieces 22 are arranged on the outer surface of the bottom pipe 21 in an annular array. A number of first through-holes 24 are formed on the outer surface of the inner pipe 23 in an annular array. A number of support bars 25 are arranged on the outer surface of the inner pipe 23 in an annular array. One ends of the number of support bars 25 are fixedly installed on the inner wall of the bottom pipe 21. The bottom pipe 21 is fixedly installed at the bottom of the first installation pipe 12.

[0056] The strengthening mechanism 6 includes a support piece 62 and a shaping ring 63. A cone spring 61 for increasing the pouring strength at the connection of the steel bars is jointly arranged between the support piece 62 and the shaping ring 63.

[0057] The support piece 62 is installed inside the cover 53, and the shaping ring 63 is installed inside the first installation pipe 12.

[0058] It should be noted that when the precast wall is completed and needs to be assembled, the precast wall pouring steel bar protruding from the foundation is inserted into the inner pipe 23. When the steel bar extends into the interior of the grouting pipe fitting 1 and touches the cone spring 61, and the set cone spring 61 is in the Figure 8 shown shape, so the steel bar extending into the interior of the grouting pipe fitting 1 through the second installation pipe 51 and the steel bar extending into the interior of the grouting pipe fitting 1 through the inner pipe 23 both contact the cone spring 61, thereby increasing the pouring strength at the connection of the steel bars through the cone spring 61.

[0059] Among them, when the precast wall is completed and assembled onto the foundation, the precast wall pouring steel bar protruding from the foundation in advance needs to be inserted into the inner pipe 23 in the precast wall. The inner pipe 23 is a pipeline embedded in the precast wall, used to guide the steel bar into the correct connection position. As the steel bar is inserted, it will extend into the interior of the grouting pipe fitting 1 and finally touch the cone spring 61. The cone spring 61 is a special spring device, and its shape design is asFigure 8 It is shown to generate a certain elastic force when the steel bar is inserted, thereby increasing the friction between the steel bar and the grouting pipe fitting.

[0060] The steel bars extending into the grouting pipe fitting 1 through the second installation pipe 51 and the steel bars extending into the grouting pipe fitting 1 through the inner pipe 23 will both contact the tapered spring 61, which means that whether it is the steel bars in the precast wall or the steel bars on the foundation, they will be supported by the tapered spring 61 after entering the grouting pipe fitting.

[0061] The special shape and elastic design of the tapered spring 61 enable it to provide a radial extrusion force when the steel bar is inserted, which helps to increase the contact area and friction between the steel bar and the grouting pipe fitting, thereby enhancing the stability of the steel bar connection.

[0062] Through the action of the tapered spring 61, the connection strength between the steel bar and the grouting pipe fitting is significantly enhanced, reducing the risk of connection failure caused by steel bar sliding or movement. The design of the tapered spring 61 increases the pouring strength of the steel bar connection and improves the safety performance of the entire prefabricated building structure. Especially when natural disasters such as earthquakes occur, it can better resist the impact of external forces.

[0063] The grouting pipe fitting 1 includes a first installation pipe 12. A spiral rib 14 is wound around the outer surface of the first installation pipe 12. An outpouring pipe 11 is arranged on the upper part of the outer surface of the first installation pipe 12. A feed pipe 13 and a through-grout pipe 15 are arranged on the lower part of the outer surface of the first installation pipe 12. The spiral rib 14 is in a spiral shape and the cross-section of the spiral rib 14 is in the shape of the letter "π", which can increase the overall strength of the precast wall when cement is poured.

[0064] It should be noted that during pouring, cement is poured into the interior of the first installation pipe 12 through the feed pipe 13. The cement first fills the interior of the bottom pipe 21, and then the cement fills the inner pipe 23. The inner pipe 23 is a guide for guiding the steel bar, and the arranged support bars 25 increase the strength of the wall connection. Then the poured cement will enter the interior of the connection mechanism 3 through the through-grout pipe 15, and then enter another first installation pipe 12 buried in the wall through the connection mechanism 3. The arranged through pipe 4 is used for gas to pass through the through pipe 4 during the grouting process to ensure that there are no bubbles in the grouted cement. The cement entering the interior of the first installation pipe 12 will contact the tapered spring 61 and fill the interior of the first installation pipe 12 to increase the strength of the cement, making the connection of the cement more firm;

[0065] When the first installation pipe 12 is filled with cement, the cement will enter the cover 53 and then circulate through the through pipe 4. The setting of the rib ring 55 enables the cement to be adsorbed more firmly in the cover 53. When the interiors of both covers 53 are filled with cement, the excess cement will be discharged through the outpouring pipe 11.

[0066] Embodiment 3. For the connecting mechanism 3 proposed in Embodiment 1, this embodiment provides a further technical solution for the connecting mechanism 3.

[0067] The connecting mechanism 3 includes a support pipe 34. A plurality of slurry outlet holes 36 distributed in an annular array are formed on the outer surface of the support pipe 34. Mounting ring frames 37 are sleeved on both sides of the outer surface of the support pipe 34. A plurality of ribs 35 distributed in an annular array are arranged between the two mounting ring frames 37. A support frame 38 is arranged on one side of the inner wall of the support pipe 34. A through pipe 32 is arranged inside the support frame 38. External connecting sleeves 30 are arranged inside the two mounting ring frames 37. A wire mesh cover 31 sleeved on the outer surface of the ribs 35 is jointly arranged between the two external connecting sleeves 30. A plurality of circular holes 39 distributed in an annular array are formed on the outer surface of the wire mesh cover 31. Steel wire strips 33 are arranged inside the plurality of circular holes 39. One end of the support pipe 34 is fixedly connected to the slurry through pipe 15, and the other end of the support pipe 34 is fixedly connected to the feed pipe 13.

[0068] It should be noted that when the precast wall is first poured, the cement first adheres to the outer surfaces of the wire mesh cover 31 and the steel wire strips 33. The provided wire mesh cover 31 is made of a microporous metal mesh, which can prevent a large amount of cement from pouring into the inside of the wire mesh cover 31. After the cement is poured into the first installation pipe 12, the cement will enter the inside of the support pipe 34 through the slurry through pipe 15. The through pipe 32 increases the strength of the connection between the support pipe 34 and the slurry through pipe 15. After the cement enters the inside of the support pipe 34, the cement will flow out through the slurry outlet holes 36 to fill the inside of the wire mesh cover 31. The provided ribs 35 support the shape of the wire mesh cover 31, making the cross-section of the wire mesh cover 31 in a wavy shape, thereby increasing the strength of the cement pouring.

[0069] Among them, during the initial pouring process, the cement will first adhere to the outer surfaces of the wire mesh cover 31 and the steel wire strips 33. The wire mesh cover 31 is made of a microporous metal mesh. This design can effectively prevent a large amount of cement from directly entering the inside of the wire mesh cover, but instead allows the cement to form a layer of coating on the outer surface. The wire mesh cover 31 is made of a microporous metal mesh material. On the one hand, it can prevent a large amount of cement from entering the inside, and on the other hand, it can also provide additional support force to enhance the adhesiveness of the cement.

[0070] After the cement is poured into the first installation pipe 12, the cement will enter the inside of the support pipe 34 through the slurry through pipe 15, ensuring that the cement can be evenly distributed throughout the connecting mechanism. The design of the through pipe 32 aims to increase the strength of the connection between the support pipe 34 and the slurry through pipe 15. After the cement enters the inside of the support pipe 34, it flows out through the slurry outlet holes 36 to fill the inside of the wire mesh cover 31, which helps to ensure that the cement can be evenly distributed and at the same time increases the filling density inside the wire mesh cover 31, thereby enhancing the overall structural strength.

[0071] The rib 35 is designed to support the shape of the wire mesh cover 31, making its cross-section wavy. This wavy design increases the structural strength after the cement is poured because the wavy surface provides more contact area, thereby enhancing the adhesion between the cement and the structure.

[0072] Through the design of the wire mesh cover 31, the support pipe 34, and the rib 35, the structural strength after the cement is poured is increased, making the connection part more durable. The microporous design of the wire mesh cover 31 effectively prevents a large amount of cement from entering the interior, thus avoiding waste of cement and ensuring that a protective layer of cement is formed on the outer surface.

[0073] The design of the through pipe 32 enhances the strength of the connection between the support pipe 34 and the grout pipe 15, further improving the overall stability of the connection mechanism. The rib 35 makes the cross-section of the wire mesh cover 31 wavy, increasing the contact area between the cement and the structure, thereby enhancing the bonding performance of the cement and improving the tensile strength of the connection part.

[0074] The plugging mechanism 7 includes a support ring 81. A plurality of sealing pieces 82 are arranged on the inner wall of the support ring 81 in an annular array distribution. The support ring 81 is arranged inside the grout pipe 15 and the slurry outlet pipe 11.

[0075] It should be noted that when a single grouting pipe fitting 1 is needed to pour the precast wall, the support ring 81 can be installed inside the grout pipe 15. At this time, the sealing piece 82 can prevent external cement from entering the grout pipe 15;

[0076] When two grouting pipe fittings 1 are spliced and used, in order to prevent the slurry outlet pipe 11 located inside the precast wall from pouring in cement, the support ring 81 is installed inside the slurry outlet pipe 11, and the sealing piece 82 can prevent external cement from entering the slurry outlet pipe 11.

[0077] The plugging mechanism 7 includes a collar 91. A plurality of arc-shaped pieces 92 are arranged on the inner wall of the collar 91 in an annular array distribution. The collar 91 is arranged inside the grout pipe 15.

[0078] Among them, when two grouting pipe fittings 1 are spliced and used, the collar 91 can be placed at the connection between the grout pipe 15 and the support pipe 34. The arranged arc-shaped pieces 92 do not prevent the cement from pouring into the through pipe 32, and the setting of the arc-shaped pieces 92 can increase the connection strength between the grout pipe 15 and the support pipe 34.

[0079] The present invention also provides a component assembly method for prefabricated components of an assembled building. The specific assembly method is as follows:

[0080] Step 1: During assembly, connect the connecting mechanism 3 with the two grouting pipe fittings 1. Then insert the steel bars of the precast wall into the pipe jacking mechanism 5 so that the steel bars extend into the interior of the grouting pipe fitting 1. Next, install the connecting mechanism 2 at the bottom of the grouting pipe fitting 1. Finally, use a mold to pour cement for the pipe jacking mechanism 5, the grouting pipe fitting 1, the connecting mechanism 2, and the connecting mechanism 3.

[0081] Step 2: The poured cement is only poured on the outer surfaces of the grouting pipe fitting 1, the pipe jacking mechanism 5, the through pipe 4, the connecting mechanism 3, and the connecting mechanism 2. To prevent the cement from entering the interior of the grouting pipe fitting 1, use the blocking mechanism 7 to block the feed hole of one of the grouting pipe fittings 1 buried inside the cement wall. Since both grouting pipe fittings 1 are located inside the wall during pouring, but the slurry outlet pipe 11 and the feed pipe 13 of one of the grouting pipe fittings 1 extend outside the wall, which facilitates pouring cement into the interiors of the grouting pipe fitting 1, the connecting mechanism 2, and the connecting mechanism 3 during the subsequent assembly of the precast wall.

[0082] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
