Description

Technical Field

[0001] This invention relates to the technical field of building construction, specifically to a prefabricated wall system, its reinforcement and leveling device, and construction method. Background Technology

[0002] Prefabricated buildings are a new type of construction that consists of multiple prefabricated components assembled on-site. These components are manufactured in factories using molds, and this method has advantages such as ease of operation and short construction period.

[0003] Chinese invention patent CN106437138A discloses a prefabricated wall template, which includes a parallel first wall panel and a second wall panel. A steel wire is provided between the first wall panel and the second wall panel. The steel wire extends along the width direction of the wall template and is bent into alternating trapezoids. The short sides of the trapezoids are respectively connected to the first wall panel and the second wall panel. A fixing strip is provided on the inner surface of the first wall panel and the second wall panel. The fixing strip extends along the height direction of the wall template and fixes the short sides of the trapezoids to the first wall panel or the second wall panel.

[0004] The aforementioned patent describes a prefabricated wall template with fewer internal components and easier assembly, but its connection structure is relatively fragile, and the wall is easily damaged by external forces. Summary of the Invention

[0005] To overcome the above problems, this invention proposes a prefabricated wall, its reinforcement and leveling device, and construction method, which uses grouting to fix the wall instead of the traditional fixing method, making the connection between adjacent walls more firm and stable.

[0006] The technical solution of the present invention is as follows:

[0007] A prefabricated building wall includes four sets of horizontal wall sections, four sets of corner wall sections, a top plate, and a bottom plate. First reinforcing bars are fixed at both ends of each horizontal wall section. Each corner wall section is L-shaped, with a third reinforcing bar at one end and a fourth reinforcing bar at the other. One first reinforcing bar is staggered with the third reinforcing bar of one corner wall section; another first reinforcing bar is staggered with the fourth reinforcing bar of another corner wall section. Second reinforcing bars are fixed at both the top and bottom of each horizontal wall section. The top second reinforcing bar is fitted into a through hole in the top plate, and the bottom second reinforcing bar is fitted into a through hole in the bottom plate. A first grouting hole is provided at the top of each first reinforcing bar in the horizontal wall section. The horizontal wall sections are fixed to the corner wall sections, top plate, and bottom plate by grouting.

[0008] Furthermore, the first, third, and fourth reinforcing bars are U-shaped reinforcing bars, while the second reinforcing bar is a straight reinforcing bar.

[0009] Furthermore, the horizontal section of the wall is composed of two spliced ​​walls. One end of the spliced ​​wall is fixed with a first steel bar, and the other end has a cavity. A connecting device is fixed in the cavity. The two connecting devices of the spliced ​​walls are centrally symmetrical. A second grouting hole is opened on the outer wall of the spliced ​​wall above the connecting device.

[0010] Furthermore, the connecting device includes a threaded rod, a fixed rod, and multiple movable blocks. The threaded rod and the fixed rod are fixed sequentially from the inside to the outside of the cavity. One end of the threaded rod is rotatably connected to the top or bottom of the cavity, and the other end of the threaded rod is fixed to the first gear. The first gear meshes with the second gear. The center of the second gear is fixed to one end of the linkage rod, and the other end of the linkage rod passes through the spliced ​​wall and is fixed to the handwheel. The movable block is L-shaped, and the corner end of the movable block extends to the outside of the cavity. Both the threaded rod and the fixed rod pass through the movable block. The threaded rod is threadedly connected to the movable block, and the fixed rod is slidably connected to the movable block.

[0011] Furthermore, the corner ends of the moving block are triangular.

[0012] Furthermore, the corner section of the wall is divided into a first cavity and a second cavity by a second baffle. The third reinforcing bar is disposed in the first cavity, and the open end of the third reinforcing bar is fixed to the second baffle. The second cavity is provided with a spring, a first baffle and a fourth reinforcing bar in sequence from the inside to the outside. One end of the spring is fixed to the inner wall of the corner section of the wall, the other end of the spring is fixed to one end of the first baffle, and the other end of the first baffle is fixed to the open end of the fourth reinforcing bar.

[0013] A reinforcement and leveling device for reinforcing prefabricated walls includes a telescopic rod, four rotating rods, and two folding plates. The telescopic rod is rectangular, and a first connector is fixed to each of its two perpendicular sides at the top and bottom. Each first connector has a first groove in its center. A second connector is fixed to one end of each rotating rod, and a second groove is formed in the center of each second connector. A groove is formed at the end of the rotating rod that connects to the second connector. A connecting post is sleeved between the first and second grooves. A folding plate is fixed between two adjacent rotating rods.

[0014] A construction method for prefabricated walls and their reinforcement and leveling devices, used for constructing prefabricated walls and reinforcement and leveling devices, includes the following steps:

[0015] Step S10: Select whether to use a modular wall according to requirements, and insert the horizontal section of the wall into the base plate;

[0016] Step S20: Insert a wall corner segment between the perpendicular horizontal segments of the wall;

[0017] Step S30: Unfold the reinforcement and leveling device and fix it at the corner of the wall corner section.

[0018] Step S40: Insert multiple steel bars of the same direction and length as the spring into the second cavity, with the steel bars positioned around the spring;

[0019] Step S50: Grout is injected into the part where the horizontal section of the wall and the corner section of the wall intersect through the first grouting hole;

[0020] Step S60: Install the top plate and inject grout into the through holes of the top plate;

[0021] Step S70: Fix the reinforcement and leveling device to the top plate.

[0022] Furthermore, step S10 specifically includes:

[0023] Step S11: Connect the ends of a pair of interlocking wall panels equipped with connecting devices together.

[0024] Step S12: Rotate the two handwheels in opposite directions so that the two handwheels drive the threaded rod to rotate through the linkage rod and gear. The two threaded rods drive multiple sets of moving blocks to fit together in pairs.

[0025] Step S13: Grout is injected into the connecting device through the second grouting hole until the entire cavity is filled.

[0026] Furthermore, step S50 specifically includes:

[0027] Step S51: Use a mold to seal the connection node between the horizontal section and the corner section of the wall;

[0028] Step S52: Grout is injected inward through the first grouting hole;

[0029] Step S53: Once the slurry reaches the designed strength, remove the sealing mold and the reinforcing bars in the second cavity.

[0030] The present invention has the following beneficial effects:

[0031] 1. This invention uses grouting to fix the wall instead of the traditional fixing method, making the connection between adjacent walls more secure and stable.

[0032] 2. This invention can divide a long horizontal section of a wall into two spliced ​​wall sections to facilitate the transportation of the wall sections. When it is necessary to install the spliced ​​wall sections, the handwheel can be turned to drive the moving blocks of the two spliced ​​wall sections to fit together, thereby achieving the initial fixation of the two spliced ​​wall sections. Grout is then injected into the connecting device through the second grouting hole to achieve the fixation of the spliced ​​wall sections.

[0033] 3. The two ends of the interlocking movable blocks are inverted triangular structures to facilitate the fit between the two movable blocks.

[0034] 4. A spring is installed in the second cavity of the corner section of the wall. After the wall construction is completed, the spring and the first baffle work together to counteract the deformation caused by the thermal expansion and contraction of the wall, so as to enhance the stability of the wall.

[0035] 5. The wall of the present invention is also equipped with a reinforcement and leveling device. The reinforcement and leveling device has a telescopic structure. It is kept in a retracted state during transportation and storage to facilitate transportation and storage. It is expanded during wall construction. The horizontal sections of the adjacent wall are kept vertical by rotating the rod, and the horizontal sections, corner sections, and top and bottom plates of the wall are kept vertical by folding the plate. After construction is completed, the reinforcement and leveling device can be fixed to other parts of the wall by means of screws or other methods to further reinforce the entire wall.

[0052] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0053] like Figures 1-14 As shown, the prefabricated building wall of this embodiment includes four sets of horizontal wall sections 1, four sets of corner wall sections 2, a top plate 4, and a bottom plate 5. First reinforcing bars 11 are fixed at both ends of the horizontal wall sections 1. The corner wall sections 2 are L-shaped, with third reinforcing bars 21 and fourth reinforcing bars 23 at each end. One first reinforcing bar 11 is staggered with the third reinforcing bar 21 of one corner wall section 2; another first reinforcing bar 11 is staggered with the fourth reinforcing bar 23 of another corner wall section 2. Second reinforcing bars 12 are fixed at both ends of the horizontal wall sections 1. The top second reinforcing bar 12 is fitted into the through hole of the top plate 4, and the bottom second reinforcing bar 12 is fitted into the through hole of the bottom plate 5. A first grouting hole 13 is opened at the top of the first reinforcing bar 11 in the horizontal wall section 1. The horizontal wall sections 1 are fixed with the corner wall sections 2, the top plate 4, and the bottom plate 5 by grouting.

[0054] The first steel bar 11 of the horizontal section 1 of the wall is inserted into the third steel bar 21 and the fourth steel bar 23 of the corner section 2 of the two walls, and grout is injected into the part where the steel bars intersect through the first grouting hole 13 to fix the walls together. The method of grouting a large area is used instead of the traditional method of reinforcing a small part of the prefabricated wall by inserting steel bars, which enhances the connection strength between the walls and enhances the stability of the walls.

[0055] Furthermore, the first reinforcing bar 11, the third reinforcing bar 21 and the fourth reinforcing bar 23 are U-shaped reinforcing bars, and the second reinforcing bar 12 is a straight reinforcing bar.

[0056] The U-shaped steel bar structure allows for a larger contact area between the first steel bar 11 and the third steel bar 21 and the fourth steel bar 23 during grouting, resulting in a more robust and stable connection.

[0057] Furthermore, the horizontal section 1 of the wall is composed of two spliced ​​wall sections 14. One end of the spliced ​​wall section 14 is fixed with a first steel bar 11 in the horizontal direction, and the other end has a cavity. A connecting device 15 is fixed in the cavity. The two connecting devices 15 of the spliced ​​wall sections 14 are centrally symmetrical. A second grouting hole 16 is opened on the outer wall of the spliced ​​wall section 14 above the connecting device 15.

[0058] Furthermore, the connecting device 15 includes a threaded rod 151, a fixed rod 152, and multiple movable blocks 153. The threaded rod 151 and the fixed rod 152 are fixed in sequence from the inside to the outside of the cavity. One end of the threaded rod 151 is rotatably connected to the top or bottom of the cavity, and the other end of the threaded rod 151 is fixed to the first gear 154. The first gear 154 meshes with the second gear 155. The center of the second gear 155 is fixed to one end of the linkage rod 156, and the other end of the linkage rod 156 passes through the spliced ​​wall 14 and is fixed to the handwheel 157. The movable block 153 is L-shaped, and the corner end of the movable block 153 extends to the outside of the cavity. Both the threaded rod 151 and the fixed rod 152 pass through the movable block 153. The threaded rod 151 is threadedly connected to the movable block 153, and the fixed rod 152 is slidably connected to the movable block 153.

[0059] The longer horizontal section 11 of the wall is divided into two spliced ​​wall sections 14 to facilitate the transportation of the wall sections. When it is necessary to install the spliced ​​wall sections 14, the handwheel 157 can be turned to drive the moving blocks 153 of the two spliced ​​wall sections 14 to fit together, so as to achieve the initial fixation of the two spliced ​​wall sections 14. Grout is then injected into the connecting device 15 through the second grouting hole 16 to fix the spliced ​​wall sections 14.

[0060] Furthermore, the corner of the moving block 153 is triangular.

[0061] The two ends of the interlocking movable blocks are inverted triangular structures to facilitate the fit between the two movable blocks.

[0062] Furthermore, the corner section 2 of the wall is divided into a first cavity 26 and a second cavity 27 by the second baffle 25. The third reinforcing bar 21 is set in the first cavity 26, and the open end of the third reinforcing bar 21 is fixed to the second baffle 25. The second cavity 27 is provided with a spring 22, a first baffle 24 and a fourth reinforcing bar 23 in sequence from the inside to the outside. One end of the spring 22 is fixed to the inner wall of the corner section 2 of the wall, and the other end of the spring 22 is fixed to one end of the first baffle 24. The other end of the first baffle 24 is fixed to the open end of the fourth reinforcing bar 23.

[0063] A spring 22 is installed in the second cavity 27 of the corner section 2 of the wall. After the wall construction is completed, the spring 22 and the first baffle 24 cooperate to counteract the deformation caused by the thermal expansion and contraction of the wall, so as to enhance the stability of the wall.

[0064] A reinforcement and leveling device for reinforcing prefabricated walls includes a telescopic rod 31, four rotating rods 32, and two folding plates 33. The telescopic rod 31 is rectangular, and a first connector 311 is fixed to both the top and bottom perpendicular sides of the telescopic rod 31. A first groove 312 is formed in the middle of each first connector 311. A second connector 321 is fixed to one end of each rotating rod 32. A second groove 322 is formed in the middle of each second connector 321. A groove is formed at the end of the rotating rod 32 that connects to the second connector 321. A connecting post 34 is sleeved between the first groove 312 and the second groove 322. A folding plate 33 is fixed between two adjacent rotating rods 32.

[0065] The wall of the present invention is also equipped with a reinforcement and leveling device 3. The reinforcement and leveling device 3 has a telescopic structure. It is kept in a retracted state during transportation and storage to facilitate transportation and storage. It is expanded during wall construction. The adjacent horizontal wall sections 1 are kept vertical by rotating rod 31, and the horizontal wall sections 1, corner wall sections 2, and top plate 4 are kept vertical to bottom plate 5 by folding plate 33. After construction is completed, the reinforcement and leveling device 3 can be fixed to other parts of the wall by means of screws passing through it, so as to further reinforce the entire wall.

[0066] A construction method for prefabricated walls and their reinforcement and leveling devices, used for constructing prefabricated walls and reinforcement and leveling devices, includes the following steps:

[0067] Step S10: Select whether to use the spliced ​​wall 14 according to the requirements, and insert the horizontal section 1 of the wall into the base plate 5.

[0068] Step S11: Connect the ends of a pair of interlocking wall panels 14 equipped with connecting devices 15 together.

[0069] Step S12: Rotate the two handwheels 157 in opposite directions so that the two handwheels 157 drive the threaded rod 151 to rotate through the linkage rod 156 and the gear. The two threaded rods 151 drive multiple sets of moving blocks 153 to fit together in pairs.

[0070] Step S13: Grout is injected into the connecting device 15 through the second grouting hole 16 until the entire cavity is filled.

[0071] Step S20: Insert wall corner segment 2 between the perpendicular horizontal wall segments 1;

[0072] Step S30: Unfold the reinforcement and leveling device 3 and fix the reinforcement and leveling device 3 at the corner of the wall corner section 2.

[0073] Screws are used to pass through the rotating rod 32 and extend into the horizontal section 1 of the wall to fix the reinforcing and leveling device 3 to the wall. When the rotating rod 32 is fully extended, the folding plate 33 is in a plane. If the part connecting the horizontal section 1 and the corner section 2 of the wall is not grouted enough or is not level due to installation errors, the folding plate 33 will bend. If the top plate 4 or bottom plate 5 is not installed perpendicular to the horizontal section 1 and the corner section 2 of the wall, the rotating rod 32 and the folding plate 33 will tilt in the corresponding direction.

[0074] Step S40: Insert multiple steel bars of the same direction and length as the spring 22 into the second cavity 27, with the steel bars positioned around the spring 22.

[0075] The reinforcing bars can prevent the spring 22 from deforming when grouting is carried out through the first grouting hole 13.

[0076] Step S50: Grout is injected into the part where the horizontal section 1 of the wall and the corner section 2 of the wall are connected through the first grouting hole 13;

[0077] Step S51: Use a mold to seal the connection node between the horizontal section 1 and the corner section 2 of the wall;

[0078] Step S52: Grout is injected inward through the first grouting hole 13;

[0079] Step S53: Once the slurry reaches the design strength, remove the sealing mold and the reinforcing bars in the second cavity 27.

[0080] Step S60: Install the top plate 4 and inject grout into the through hole of the top plate 4;

[0081] After grouting is completed, the reinforcing bars are removed so that the spring 22 and the first baffle 24 can cooperate to buffer the thermal expansion and contraction of the wall.

[0082] Step S70: Fix the reinforcing and leveling device 3 to the top plate 4.

[0083] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
