Description

Technical Field

[0001] This invention relates to the field of prefabricated wall technology, specifically to an energy-saving and environmentally friendly prefabricated wall structure and its assembly method. Background Technology

[0002] Prefabricated walls utilize the principle of cast-in-place shear walls, employing galvanized light steel keel as the supporting framework and high-strength magnesium oxide flat panels as non-removable panels. Environmentally friendly, flame-retardant, lightweight mortar is poured inside the magnesium oxide flat panels to ultimately form the wall. Prefabricated walls adhere to the national policy of developing green building materials and moving away from traditional brick and tile construction, aiming to save energy, reduce dust, lower costs, accelerate construction progress, reduce labor, and improve wall quality.

[0003] Using prefabricated modular walls for house construction significantly accelerates the pace of traditional building construction while reducing dust, noise, and other pollution and disturbances to the surrounding environment, contributing to green and environmentally friendly construction projects. It also avoids disrupting the normal lives of residents near the construction site. On the construction site, workers need to assemble individual wall panels. To ensure the stability of the joints, the existing technology (publication number CN115370041A) uses screws and connecting sleeves to connect two walls. However, in this solution, the space between the two connected walls is hollow, lacking support and resulting in poor stability at the joint. Furthermore, the hollow structure affects the sound insulation and thermal insulation performance of the assembled wall. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an energy-saving and environmentally friendly prefabricated wall structure and its assembly method. A connecting block is inserted into a slot, and then cement grout is injected into two interconnected trapezoidal limiting grooves through a first grouting hole and a second grouting hole. The solidified cement is used to fix the connecting block inside the slot, thus assembling the first and second walls. The connection points of both walls are filled with cement grout, resulting in high strength and sound and heat insulation properties.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an energy-saving and environmentally friendly prefabricated wall structure, comprising a wall, wherein the wall is assembled from multiple first walls and multiple second walls;

[0006] A wall connection assembly for reinforcing the connection between the first wall and the second wall is provided between the first wall and the second wall.

[0007] The wall connection assembly includes a connecting block installed on one side of a first wall. A slot for accommodating the connecting block is provided on the other side of the first wall. Trapezoidal limiting grooves are provided inside the connecting block and at the end of the first wall away from the connecting block. After the connecting block is inserted into the slot, the trapezoidal limiting grooves inside the first wall and the second wall are connected. Two first grouting holes are provided at the bottom front side of the first wall. A second grouting hole is provided at the bottom front side of the connecting block. After the connecting block is inserted into the slot, the second grouting hole is connected to the first grouting hole located on the outside. Cement grout is injected into the trapezoidal limiting groove through the first and second grouting holes. The solidified cement grout conforms to the shape inside the trapezoidal limiting groove.

[0008] Preferably, a first trapezoidal plate is inserted into the bottom of the trapezoidal limiting groove at the end of the wall away from the connecting plug, and a second trapezoidal plate is inserted into the bottom of the trapezoidal limiting groove in the connecting plug, with the first and second trapezoidal plates located at the top of the cement slurry.

[0009] Preferably, two parallel threaded rods are fixed on the side of the second trapezoidal plate away from the first wall. A limiting hole is opened inside the first trapezoidal plate, and a threaded sleeve is rotatably connected inside the limiting hole. After the connecting block is inserted into the slot, the threaded rod is threadedly connected inside the threaded sleeve to fix the first trapezoidal plate and the second trapezoidal plate together.

[0010] Preferably, the first wall and the second wall have the same structure and the same material, and both the first wall and the second wall are made of thermal insulation and sound insulation materials.

[0011] Preferably, the first wall is provided with an indicator component for indicating the content of cement paste in the trapezoidal limiting groove;

[0012] The indicating component includes multiple vertical rods fixed to the top of the first trapezoidal plate and the top of the second trapezoidal plate. The top of the connecting block has a first insertion hole for the vertical rods to pass through, and the top of one side of the wall has a second insertion hole for the vertical rods to pass through.

[0013] Preferably, a connecting hole for accommodating the top end of the vertical rod is provided on one side of the bottom end of the first wall.

[0014] Preferably, the bottom of the first wall has multiple steel bar insertion holes at equal intervals for inserting steel bars.

[0015] This invention also provides an assembly method for an energy-saving and environmentally friendly prefabricated wall structure, comprising the following specific steps:

[0016] Step 1: Align the connecting block on one side of the second wall with the slot on one side of the first wall, and align the threaded rod with the limiting hole. Then insert the connecting block into the slot. At this time, the threaded rod is threaded into the threaded sleeve. Then insert the steel bar insertion hole at the bottom of the first wall and the steel bar insertion hole at the bottom of the second wall into the outer end of the steel bar at the designated position.

[0017] Step 2: Prepare cement slurry;

[0018] Step 3: Use a mud pump to extract the prepared cement slurry, and then insert one end of the mud pump outlet pipe into the first grouting hole so that the cement slurry extracted by the mud pump can be injected into the two connected trapezoidal limiting grooves through the first grouting hole and the second grouting hole.

[0019] Step 4: During the cement grout injection process, workers should carefully observe the top of the connection between the first and second walls. As the cement grout inside the trapezoidal limiting groove increases, it will push the first and second trapezoidal plates inside the groove, causing the vertical rods at their tops to move upwards until the tops of the first and second trapezoidal plates contact the top of the inner wall of the trapezoidal limiting groove. At this point, the top of the vertical rod will extend from inside the first and second walls. When workers observe the extended vertical rod, they can stop the grout pump. After the cement grout solidifies, the first and second walls will be fixed together, completing the assembly of the first and second walls.

[0020] Compared with the prior art, the present invention provides an energy-saving and environmentally friendly prefabricated wall structure and its assembly method, which has the following beneficial effects:

[0021] 1. By inserting the connecting block into the slot, and then injecting cement grout into the two connected trapezoidal limiting grooves through the first grouting hole and the second grouting hole, the shape of the cement grout after solidification is consistent with the shape of the assembled first trapezoidal plate and the second trapezoidal plate. The solidified cement is used to fix the connecting block in the slot, realizing the assembly of the first wall and the second wall. The connection between the two is filled with cement grout, which has high strength and can ensure the stability of the connection. Moreover, the connection between the first wall and the second wall is a solid structure. Both the first wall and the second wall are made of thermal insulation materials, which also helps to ensure the thermal insulation performance of the assembled wall.

[0022] 2. By setting a first trapezoidal plate and a second trapezoidal plate inside the trapezoidal limiting groove, and setting a vertical rod at the top of the first trapezoidal plate and the second trapezoidal plate, the vertical rod can extend out from inside the first wall and the second wall after the cement slurry inside the trapezoidal limiting groove is sufficient, so as to inform the construction personnel to stop injecting cement slurry into the trapezoidal limiting groove, which helps to enhance the convenience of construction of the present invention.

[0036] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] like Figure 1 and 2 As shown, the present invention provides an energy-saving and environmentally friendly prefabricated wall structure, including a wall 1, which is assembled from multiple first wall 11s and multiple second wall 12s. Moreover, in the present invention, the first wall 11s and the second wall 12s have the same structure and the same material. Both the first wall 11s and the second wall 12s are made of thermal insulation and sound insulation materials, which helps to enhance the thermal insulation and sound insulation performance of the assembled wall 1.

[0038] Moreover, such as Figure 3 As shown, multiple steel bar insertion holes 4 are provided at equal intervals at the bottom of the first wall 11 for inserting steel bars. When the wall 1 of the present invention is installed on the designated ground, in order to ensure the stability of the connection between the wall 1 and the ground, multiple vertical steel bars need to be left in advance at the designated installation position on the ground. The diameter of the steel bars is the same as the inner diameter of the steel bar insertion hole 4. Therefore, when installing the wall 1, the steel bars on the ground need to be inserted into the steel bar insertion hole 4 for reinforcement.

[0039] Furthermore, when assembling the first wall 11 and the second wall 12, the first wall 11 and the second wall 12 need to be fixed together, such as... Figure 1 As shown, a wall connection component 2 for reinforcing the connection between the first wall 11 and the second wall 12 is provided between the first wall 11 and the second wall 12.

[0040] like Figure 2-8 As shown, the wall connection assembly 2 of the present invention includes a connecting plug 21 installed on one side of a first wall 11. A slot 22 for accommodating the connecting plug 21 is provided on the other side of the first wall 11. Trapezoidal limiting grooves 210 are provided inside both the connecting plug 21 and the end of the first wall 11 away from the connecting plug 21. After the connecting plug 21 is inserted into the slot 22, the trapezoidal limiting grooves 210 inside the first wall 11 and the trapezoidal limiting grooves 210 inside the second wall 12 are connected. Two first grouting holes 28 are provided at the bottom front side of the first wall 11, and a second grouting hole 29 is provided at the bottom front side of the connecting plug 21. After the connector 21 is inserted into the slot 22, the second grouting hole 29 is connected to the first grouting hole 28 located on the outside. The prepared cement slurry is extracted by the mud pump and then pumped into the trapezoidal limiting groove 210 at the connection between the first wall 11 and the second wall 12 through the first grouting hole 28 and the second grouting hole 29. The solidified shape of the cement slurry is consistent with the internal shape of the trapezoidal limiting groove 210, which is two mirror-symmetrical trapezoids, small in the middle and large at both ends. Under the restriction at both ends, it can prevent the first wall 11 and the second wall 12 from separating, which helps to enhance the stability of the connection between the first wall 11 and the second wall 12.

[0041] In such Figure 5 , 7As shown in Figure 8, a first trapezoidal plate 23 is inserted into the bottom end of the trapezoidal limiting groove 210 at the end of the wall 1 away from the connecting plug 21, and a second trapezoidal plate 24 is inserted into the bottom end of the trapezoidal limiting groove 210 in the connecting plug 21. The first trapezoidal plate 23 and the second trapezoidal plate 24 are located at the top of the cement slurry. Two parallel threaded rods 25 are fixed on the side of the second trapezoidal plate 24 away from the first wall 11. A limiting hole 27 is opened inside the first trapezoidal plate 23, and a threaded sleeve 26 is rotatably connected inside the limiting hole 27. After the connecting plug 21 is inserted into the slot 22, the threaded rods 25 are threadedly connected inside the threaded sleeve 26 to fix the first trapezoidal plate 23 and the second trapezoidal plate 24 together.

[0042] Furthermore, an indicator component 3 for indicating the cement slurry content in the trapezoidal limiting groove 210 is provided inside the first wall 11; the indicator component 3 includes a plurality of vertical rods 31 fixed to the top of the first trapezoidal plate 23 and the top of the second trapezoidal plate 24, the top of the connecting block 21 is provided with a first insertion hole 32 for the vertical rods 31 to pass through, and the top of one side of the wall 1 is provided with a second insertion hole 33 for the vertical rods 31 to pass through.

[0043] As the cement slurry is injected into the trapezoidal limiting groove 210, it pushes the first trapezoidal plate 23 and the second trapezoidal plate 24, causing the vertical rod 31 to move upward. When the top of the first trapezoidal plate 23 and the top of the second trapezoidal plate 24 are in contact with the top of the inner wall of the trapezoidal limiting groove 210, the top of the vertical rod 31 extends out from inside the first wall 11 and the second wall 12, so as to inform the workers on site that the trapezoidal limiting groove 210 is filled with cement slurry and the mud pump can be turned off to stop the delivery of cement slurry.

[0044] Additionally, when it is necessary to splice the first wall 11 or the second wall 12 in the vertical direction, in order to prevent the protruding vertical rod 31 from affecting the normal splicing of the top of the first wall 11, such as Figure 6 As shown, a connecting hole 34 for accommodating the top end of the vertical rod 31 is provided on one side of the bottom end of the first wall 11. The connecting hole 34 at the bottom of the upper first wall 11 can accommodate the top end of the vertical rod 31 extending from the top end of the lower first wall 11. This helps to ensure the fit between the two upper and lower spliced ​​first walls 11 and also helps to align the two upper and lower spliced ​​first walls 11.

[0045] The assembly process of the first wall 11 and the second wall 12 is as follows:

[0046] Step 1: Align the connecting block 21 on one side of the second wall 12 with the slot 22 on one side of the first wall 11, and align the threaded rod 25 with the limiting hole 27. Then, insert the connecting block 21 into the slot 22. At this time, the threaded rod 25 is threaded into the threaded sleeve 26. Then, insert the steel bar insertion hole 4 at the bottom of the first wall 11 and the steel bar insertion hole 4 at the bottom of the second wall 12 into the outer end of the steel bar at the designated position on the ground of the construction site.

[0047] Step 2: Prepare cement slurry;

[0048] Step 3: Use a mud pump to extract the prepared cement slurry, and then insert one end of the mud pump outlet pipe into the first grouting hole 28 so that the cement slurry extracted by the mud pump can be injected into the two connected trapezoidal limiting grooves 210 through the first grouting hole 28 and the second grouting hole 29.

[0049] Step 4: During the cement slurry injection process, workers should pay attention to the top of the connection between the first wall 11 and the second wall 12. As the cement slurry inside the trapezoidal limiting groove 210 increases, it will push the first trapezoidal plate 23 and the second trapezoidal plate 24 inside the trapezoidal limiting groove 210 to move the vertical rod 31 at its top upward until the top of the first trapezoidal plate 23 and the second trapezoidal plate 24 contacts the top of the inner wall of the trapezoidal limiting groove 210. At this time, the top of the vertical rod 31 will extend out from inside the first wall 11 and the second wall 12. Workers can turn off the mud pump when they observe the extended vertical rod 31.

[0050] After the cement grout solidifies, it can be used to bond the first wall 11 and the second wall 12. On the other hand, the special shape of the cement grout can be used to further limit and reinforce the first wall 11 and the second wall 12, ensuring the stability of the connection between the first wall 11 and the second wall 12, thereby completing the assembly of the first wall 11 and the second wall 12.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
