Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, specifically to prefabricated buildings. Background Technology

[0002] Prefabricated wall structures (or assembled wall systems) consist of a wall composed of several prefabricated wall units. These units can be pre-assembled concrete, timber, or composite material units. Each wall unit has an identical structure, making them suitable for mass production.

[0003] To enable the assembly of wall units, each wall unit has protruding or recessed connecting structures on its sides, bottom, and top. For example, each wall unit has protruding structures on its top and left wall, and recessed structures on its bottom and right wall. When two adjacent wall units are assembled, the recessed structure on the right wall of the left wall unit mates with the protruding structure on the left wall of the right wall unit. When two adjacent wall units are assembled, the recessed structure at the bottom of the upper wall unit mates with the protruding structure at the top of the lower wall unit.

[0004] In actual production, any type of wall unit, especially concrete units, is large and heavy, requiring workers to use large lifting equipment to move them. It's impossible for any wall unit to have both convex and concave structures on its sides, top, and bottom simultaneously. This is because a large wall unit cannot simultaneously perform the following two actions: the concave structure at the bottom of one wall unit mates with the convex structure at the top of the wall unit below it, and the convex structure on the left wall of one wall unit mates with the concave structure on the right wall of the wall unit to the left. Therefore, there are two ways for wall units to engage. The first way is to have a vertically oriented slider on the left wall of one wall unit, a vertically oriented groove on the right wall of one wall unit, a convex structure at the top, and a concave structure at the bottom. During assembly, the wall unit being assembled moves downwards, its left-side slider mates with the groove on the right wall of the wall unit to the left, and its bottom concave structure mates with the convex structure at the top of the wall unit below it. In the second method, the top of the wall unit is equipped with a slider that runs vertically, the bottom of the wall unit is equipped with a groove that runs vertically, the left wall of the wall unit is equipped with an outward convex structure, and the right wall of the wall unit is equipped with an inward concave structure. During assembly, the wall unit being assembled moves to the left, and the groove at its bottom engages with the slider at the top of the wall unit below, and the outward convex structure on its left wall engages with the inward concave structure on the right wall of the left wall unit.

[0005] Wall units are not plastic building blocks, especially concrete units. The sliders and grooves mesh, and even slight deviations during relative displacement can cause assembly to stall, or the grooves or sliders to crack or break. Furthermore, engineering materials have large tolerances, and wall units using sliders and grooves may become loose or misaligned, affecting the overall quality of the wall. Summary of the Invention

[0006] The technical problem solved by this invention is: a prefabricated wall structure (or assembled wall), in which wall units are assembled using convex and concave structures, but the sliding block groove cooperation between wall units is eliminated.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a green and low-carbon assembled wall, comprising several wall units, the top of which has an outward protruding structure and the bottom of which has an inward concave structure. Each wall unit has a vertical left-side mating hole and a right-side mating hole. The left wall of the wall unit has a left connecting hole communicating with the left-side mating hole, and the right wall of the wall unit has a right connecting hole communicating with the right-side mating hole. In two adjacent wall units, a vertical connecting plate is fitted into the right-side mating hole of the left wall unit. The connecting plate has a connecting protrusion that passes through the right connecting hole to the right and mates with the left connecting hole of the right wall unit.

[0008] According to the above technical solution, the leftmost wall unit in the first layer of the assembled wall is fixed to the foundation or floor. The right wall unit, which cooperates with the leftmost wall unit, is lowered directly onto the foundation or floor along the right wall of the leftmost wall unit. Then, the workers connect and lock the leftmost and right wall units together.

[0009] Specifically, the worker inserts the connecting plate into the right mating hole of the leftmost wall unit, then moves the connecting plate to the right. The connecting protrusion on the connecting plate passes through the right connecting hole to the right and mates with the left connecting hole of the right wall unit, thus achieving the connection and locking of the leftmost wall unit and the right wall unit.

[0010] Following the assembly method described above for the leftmost and rightmost wall units, assemble the wall unit to the right of the rightmost wall unit. After completing the assembly of the first layer of wall units, assemble the second layer of wall units on top of the first layer of wall units using the same method, and then assemble the third layer of wall units on top of the second layer of wall units using the same method, until the assembly of all layers of wall units of the assembled wall is completed.

[0011] Compared to the prefabricated wall structure using sliders and grooves in the prior art, the present invention connects two wall units by first placing them in place and then using accessories, thus eliminating the slider and groove connection between the wall units, avoiding potential cracking or breakage of the grooves or sliders, and avoiding affecting the quality of the entire wall.

[0012] The connecting protrusion in the left mating hole of the right wall unit has a T-shaped structure. A vertical locking plate is fitted in the left mating hole of the right wall unit. The locking plate has a T-shaped locking groove. The T-shaped locking groove engages with the connecting protrusion to prevent the connecting protrusion from retracting into the left wall unit, effectively locking the left and right wall units.

[0013] An assembly method for a green and low-carbon modular wall includes the following steps:

[0014] The first step is to install a raised structure on the foundation or floor of the wall to be assembled, and fix the first wall unit to the foundation or floor by the cooperation of the concave structure at the bottom and the raised structure.

[0015] The second step involves using large mechanical equipment to lift the second wall unit and move it to the right side of the first wall unit. The second wall unit is aligned with the first wall unit on the left and right, and the concave structure at the bottom of the second wall unit matches the convex structure on the foundation or floor.

[0016] The third step is for the worker to insert the connecting plate from top to bottom into the right-side mating hole of the first wall unit, and move the connecting plate to the right so that the connecting protrusion passes through the right connecting hole to the right and mates with the left connecting hole of the second wall unit.

[0017] In the fourth step, the worker inserts the locking plate from top to bottom into the mating hole on the left side of the second wall unit, where the T-shaped locking groove mates with the connecting protrusion.

[0018] The fifth step is to assemble the third wall unit on the right side of the second wall unit according to the second to fourth steps above, and assemble the fourth wall unit on the right side of the third wall unit according to the second to fourth steps above. In this way, assemble the N+1 wall unit on the right side of the Nth wall unit according to the second to fourth steps above, until the first layer of wall units of the wall assembly is completed.

[0019] The sixth step is to assemble the second wall unit on the first wall unit. The concave bottom structure of the second wall unit matches the convex top structure of the first wall unit. Otherwise, the assembly steps of the second wall unit are the same as those of the first wall unit. Then, assemble the third wall unit on the second wall unit, and so on until the Nth wall unit is assembled. The wall assembly is then complete.

[0020] It is generally known that a ceiling is installed on an assembled wall, and the ceiling can press the assembled wall tightly against it.

[0021] Unlike existing technologies such as concrete pouring, which generates dust and requires concrete mixing, this invention assembles walls into pre-produced wall units, making it environmentally friendly and low-carbon. Attached Figure Description

[0042] Combination Figure 1 , Figure 2 , Figure 5 , Figure 8 , Figure 9A green and low-carbon prefabricated wall system includes several wall units 10. The top of each wall unit has an outwardly protruding structure 11, and the bottom of each wall unit has an inwardly concave structure 12. Each wall unit has a vertical left-side mating hole 13 and a right-side mating hole 14. The left wall of each wall unit has a left connecting hole 130 that communicates with the left-side mating hole, and the right wall of each wall unit has a right connecting hole 140 that communicates with the right-side mating hole. In two adjacent wall units, a vertical connecting plate 20 is fitted into the right-side mating hole of the left wall unit. The connecting plate has a connecting protrusion 21 that passes through the right connecting hole to the right and mates with the left connecting hole of the right wall unit.

[0043] refer to Figure 5 The connecting protrusion 21 in the left-side mating hole 13 of the right wall unit has a T-shaped structure, and a vertical locking plate 30 is fitted in the left-side mating hole 13 of the right wall unit. (See reference) Figure 7 The lock plate is provided with a T-shaped lock groove 31, which cooperates with the connecting protrusion.

[0044] An assembly method for a green and low-carbon modular wall includes the following steps.

[0045] The first step involves installing a raised structure on the foundation or floor where the wall to be assembled will be installed. The first wall unit 101 is then fixed to the foundation or floor by the engagement of its bottom recessed structure 12 with the raised structure. The raised structures on the foundation or floor are arranged in a row, for use by the first layer of wall units; that is, the bottom recessed structure 12 of the first layer of wall units engages with the raised structure on the foundation or floor. The bottom recessed structure 12 of the second layer of wall units, superimposed on the first layer of wall units, engages with the top raised structure 11 of the first layer of wall units. (Refer to...) Figure 10 , Figure 11 .

[0046] The second step involves using heavy machinery to lift the second wall unit 102 and move it to the right side of the first wall unit 101. The second wall unit is aligned left and right with the first wall unit, and the concave structure 12 at the bottom of the second wall unit engages with the convex structure on the foundation or floor. The left wall of the second wall unit is attached to the right wall of the first wall unit. This allows the second wall unit to be positioned very quickly. The several right connecting holes 140 on the right wall of the first wall unit 101 are aligned one-to-one with the several left connecting holes 130 on the left wall of the second wall unit 102.

[0047] In the third step, the worker inserts the connecting plate 20 from top to bottom into the right-side mating hole 14 of the first wall unit 101, and moves the connecting plate 20 to the right so that the connecting protrusion 21 passes through the right connecting hole 140 and mates with the left connecting hole 130 of the second wall unit 102. The right-side mating hole 14 needs to be large enough to allow the connecting plate 20 to extend into it. The bottom end of the connecting plate 20 contacts the foundation or floor, and the connecting protrusions 21 on the connecting plate can be aligned one by one with the right connecting holes 140. Then, the worker moves the connecting plate 20 to the right so that the connecting protrusions 21 mate with the right connecting holes 140 and the left connecting hole 130 of the second wall unit 102, as shown in the reference. Figure 3 , Figure 4 , Figure 8 , Figure 9 .

[0048] In the fourth step, the worker inserts the locking plate 30 from top to bottom into the mating hole 13 on the left side of the second wall unit 102, where the T-shaped locking groove 31 engages with the connecting protrusion 21. This prevents the connecting protrusion 21 from retracting, achieving a tight fit between the first and second wall units and preventing them from separating. (See reference...) Figure 9 .

[0049] The fifth step is to assemble the third wall unit on the right side of the second wall unit 102 according to the second to fourth steps above, and assemble the fourth wall unit on the right side of the third wall unit according to the second to fourth steps above. In this way, assemble the N+1th wall unit on the right side of the Nth wall unit according to the second to fourth steps above, until the first layer of wall units of the wall assembly is completed.

[0050] The sixth step involves assembling the second wall unit onto the first wall unit. The concave bottom structure of the second wall unit mates with the convex top structure of the first wall unit. Aside from this, the assembly steps for the second wall unit are the same as those for the first. Then, the third wall unit is assembled onto the second wall unit using the same steps, and so on, until the Nth wall unit is assembled, thus completing the wall assembly. (Refer to...) Figure 10 , Figure 11 .

[0051] As an improvement, combined Figure 8 , Figure 9When the T-shaped locking groove 31 engages with the connecting protrusion 21, the left wall of the locking plate 30 abuts against the left wall of the left-side mating hole 13 of the right wall unit. The connecting protrusion 21, which extends into the left-side mating hole 13 of the second wall unit, is locked by the locking plate 30. If the connecting protrusion wants to retract into the first wall unit 101, the connecting protrusion will cause the locking plate 30 to move to the left, and the left wall of the locking plate abuts against the left wall of the left-side mating hole 13 of the right wall unit, preventing the connecting protrusion 21 from retracting. In this way, the engagement of the locking plate and the connecting protrusion can prevent the two adjacent wall units from separating left and right, keeping the two adjacent wall units in close contact, which is beneficial to improving the quality of the assembled wall.

[0052] A vertical first support plate 40 is fitted into the right-side fitting hole 14 of the left wall unit. The first support plate and the connecting plate 20 are together supported in the right-side fitting hole 14 of the left wall unit. Filling the right-side fitting hole 14 helps to ensure the strength of the wall unit and also makes the connecting plate 20 stable in the wall unit.

[0053] Combination Figure 8 , Figure 9 A vertical second support plate 50 is fitted into the left-side mating hole 13 of the right wall unit. The second support plate and the locking plate 30 are together tightened into the left-side mating hole 13 of the right wall unit, filling the left-side mating hole 13. This helps to ensure the strength of the wall unit and also makes the locking plate 30 stable in the wall unit. In addition, the locking plate 30 can be designed to be thinner, which makes it easier for workers to operate and also makes it easier for the locking plate to mate with the connecting protrusion 21.

[0054] As an improvement, combined Figure 5 , Figure 4 , Figure 6The connecting plate 20 has a vertical slot 22. A worker holds the top of the push rod 60, aligns the bottom of the push rod with the slot, tilts the push rod, and pushes the bottom of the push rod downwards along the slot 22, causing the connecting plate 20 to move to the right. This allows the connecting protrusion 21 to pass through the right connecting hole 140 and engage with the left connecting hole 130 of the second wall unit 102. The slot 22 and the connecting protrusion 21 are located on the left and right sides of the connecting plate 20, respectively. Because the right-side engaging hole 14 is relatively deep, it is difficult for the worker to manually move the connecting plate 20 horizontally to the right to engage the connecting protrusion 21 with the right connecting hole 140 and the left connecting hole 130. Therefore, this invention designs the push rod 60 and the slot 22 used in conjunction with the push rod. In actual operation, the bottom end of the push rod 60 always maintains engagement with the slot 22. The bottom end of the push rod can move up and down along the slot. The worker applies force to the top end of the push rod, causing the inclined bottom end of the push rod to exert force on the connecting plate 20, thus moving the connecting plate to the right. Crucially, the connecting plate 20 needs to be moved to the right so that the connecting protrusion 21 can engage with the right connecting hole 140 and the left connecting hole 130. Therefore, the force exerted by the push rod 60 on the connecting plate 20 is concentrated on the lower part of the connecting plate, while the upper part can be moved to the right manually by the worker. The simultaneous rightward movement of both the upper and lower parts of the connecting plate achieves its rightward translation.

[0055] As a further improvement, the bottom end of the push rod 60 is provided with a cylindrical body 61, which makes it easier for workers to move the bottom end of the push rod up and down.

[0056] As a further improvement, a relief groove 141 is provided on the side wall of the mating hole 14 on the right side to allow the push rod 60 to have sufficient inclination, making it easier for the worker to push the lower part of the connecting plate 20.

[0057] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
