Description

Technical Field

[0001] The present application relates to the field of construction engineering technology, and in particular to a tool and construction method for preventing deformation and distortion of door-type wall panels. Background Art

[0002] Prefabricated wall panels are reinforced panels manufactured at a prefabrication plant or construction site for assembly. Using prefabricated wall panels to construct prefabricated, large-panel buildings can improve factory production and construction efficiency, reduce on-site wet work, save on-site labor, mitigate seasonal fluctuations, and shorten construction cycles.

[0003] The portal wall panel has only three sides: two vertical limbs and a top beam. Due to the large span of the three sides, the lower ends of the vertical limbs are suspended in the air, resulting in uneven stress at the connection between the vertical limbs and the top beam. This in turn causes cracks and distortion between the two parallel limbs, seriously hindering the construction process of the portal wall panel.

[0004] The existing solution to this problem is to connect a steel channel between two parallel vertical wall limbs to increase the stability of the portal wall panel. The steel channel is removed from the mold along with the wall panel. However, the rigidity and stability of the steel channel alone gradually decreases with length, thus affecting its ability to stabilize the connection between the vertical wall limb and the upper beam. Summary of the Invention

[0005] In order to improve the stability of the connection between the upper beam and the vertical wall limb of the portal wall panel, the present application provides a tool and a construction method for preventing the portal wall panel from deforming and twisting.

[0006] The present application provides a tool for preventing deformation and twisting of door-type wall panels, which adopts the following technical solutions:

[0007] A tool for preventing deformation and twisting of a door-type wall panel includes a horizontal steel pipe, wherein the horizontal steel pipe includes a main steel pipe and a telescopic steel pipe whose ends can be connected to reserved bolts of the door-type wall panel. The main steel pipe is a hollow structure, and the telescopic steel pipe is slidably inserted into the main steel pipe. The telescopic steel pipe is threadedly connected to the main steel pipe. When the main steel pipe is rotated, the telescopic steel pipe can slide inside the main steel pipe.

[0008] By adopting the above technical solution, the horizontal steel pipe connects the bottoms of the two vertical wall members of the portal wall panel, so that the bottoms of the vertical wall members are not in a suspended state, and the lower ends of the two vertical wall members are supported. This can bear part of the weight of the portal wall panel and share the vertical and horizontal loads of the two vertical wall members, making it difficult for the vertical wall members to twist and deform under their own gravity.

[0009] The horizontal steel tubes coordinate with the portal wall panels, acting as a framework. This allows the connectors to integrate with the wall panels, strengthens the connection, and protects the integrity of the concrete edges under load, thereby increasing the wall's bearing capacity. The horizontal steel tubes can be adjusted in length by rotating, allowing them to accommodate portal wall panels of varying sizes. When not in use, they can be retracted to a shorter length for easier transportation and storage.

[0010] Optionally, the tooling for preventing deformation and twisting of the portal wall panel further includes a first diagonal brace and a second diagonal brace capable of connecting the horizontal steel pipe and the upper beam, one end of each of the first diagonal brace and the second diagonal brace being connected to the horizontal steel pipe;

[0011] One end of the first diagonal brace away from the horizontal steel pipe is connected to one end of the second diagonal brace away from the horizontal steel pipe, and the horizontal steel pipe, the first diagonal brace and the second diagonal brace together form a triangular structure.

[0012] By adopting this technical solution, the first and second diagonal braces connect the horizontal steel tubes to the upper beam, further sharing the vertical load of the vertical wall limbs, further improving the connection force between the vertical wall limbs and the upper beam, and strengthening the connection between the upper beam and the vertical wall limbs of the portal wall panel, thereby improving the wall's bearing capacity. Furthermore, the triangular structure is stable and pressure-resistant, further enhancing the overall stability of the portal wall panel.

[0013] Optionally, one end of the first diagonal brace away from the horizontal steel pipe is hinged to one end of the second diagonal brace away from the horizontal steel pipe;

[0014] The first diagonal brace includes a first main diagonal brace and a first telescopic diagonal brace, the first telescopic diagonal brace is slidably inserted into the first main diagonal brace and is threadedly connected to the first main diagonal brace; the second diagonal brace includes a second main diagonal brace and a second telescopic diagonal brace, the second telescopic diagonal brace is slidably inserted into the second main diagonal brace and is threadedly connected to the second main diagonal brace.

[0015] By adopting the above technical solution, by adjusting the angle between the first diagonal brace and the second diagonal brace, and rotating to adjust the length of the first diagonal brace and the second diagonal brace, and coordinating with the adjustment of the length of the horizontal steel pipe, the entire tooling can be suitable for door-type wall panels of different sizes; at the same time, when not in use, the entire tooling can be shortened to a certain length for easy storage, storage and transportation.

[0016] Optionally, the first diagonal brace and the second diagonal brace are both detachably connected to the horizontal steel pipe, and a rotating component is provided between the first diagonal brace and the second diagonal brace, which can drive the first diagonal brace and the second diagonal brace to revolve around the hinged end as a fulcrum.

[0017] By adopting the above technical solution, when the portal wall panel is hoisted to the installation point, when the vertical wall limb is positioned, the first diagonal brace and the second diagonal brace can be rotated to a direction perpendicular to the horizontal steel pipe by adjusting the rotating assembly, so that the entire portal wall panel can be supported on the ground, facilitating the subsequent positioning process.

[0018] Optionally, the rotating assembly includes a motor, a screw and a rotating block; the motor is arranged on the horizontal steel pipe, one end of the screw is connected to the output shaft of the motor, the surface of the screw includes a smooth section arranged away from one end of the motor, the rotating block is slidably sleeved outside the smooth section and the rotating block and the screw are circumferentially limited; the two sides of the outer surface of the rotating block can be respectively connected to the first oblique support and the second oblique support and the rotating block can drive the first oblique support and the second oblique support to revolve around the screw when the rotating block rotates with the screw.

[0019] By adopting the above technical solution, when the portal wall panel is hoisted to the installation point, the rotating block indirectly connects the screw rod to the first and second diagonal braces when positioning the vertical wall limbs. By starting the motor, the first and second diagonal braces can be rotated about the hinged ends to a direction perpendicular to the horizontal steel pipe, supporting the entire portal wall panel on the ground and facilitating the subsequent positioning process. By adjusting the position of the first and second diagonal braces, the entire tooling can be adapted to different construction sections, improving the efficiency of portal wall panel hoisting.

[0020] Optionally, grooves are provided at both ends of the horizontal steel pipe, and the two grooves are respectively provided on both sides of the horizontal steel pipe, and the first diagonal brace and the second diagonal brace are respectively inserted into the two grooves; each groove is also embedded with a baffle that can limit the first diagonal brace or the second diagonal brace.

[0021] By adopting the above technical solution, the first diagonal brace and the second diagonal brace can be detachably inserted on both sides of the horizontal steel pipe and limited by the baffle. When the first diagonal brace and the second diagonal brace need to be rotated, the baffle is removed to separate the first diagonal brace and the second diagonal brace from the horizontal steel pipe. The operation is simple.

[0022] Optionally, a sliding groove is provided on the outer surface of the smooth section, and a protrusion capable of moving up and down along the sliding groove is provided on the inner side of the rotating block.

[0023] By adopting the above technical solution, the rotating block can move up and down along the smooth section of the screw rod. When the first diagonal support and the second diagonal support need to be rotated, the rotating block is placed outside the screw rod; when the first diagonal support and the second diagonal support do not need to be rotated, the rotating block is taken out from the upper end of the screw rod along the slide groove, and the operation is simple and quick.

[0024] Optionally, an angle adjustment assembly is further provided between the first diagonal brace and the second diagonal brace, the angle adjustment assembly comprising a first wedge block, a second wedge block and a nut disk, the screw rod further comprising a threaded section located below the smooth section, the nut disk being sleeved outside the threaded section and threadedly connected to the threaded section;

[0025] The first wedge block and the second wedge block are arranged opposite to each other, and the opposing surfaces of the two are wedge-shaped surfaces. The side of the first wedge block away from the second wedge block is fixedly connected to the first diagonal brace, and the side of the second wedge block away from the first wedge block is fixedly connected to the second diagonal brace.

[0026] The nut disk is located between the first wedge block and the second wedge block. Slideways are provided on the wedge surfaces of the first wedge block and the second wedge block. Both sides of the nut disk have protrusions that are slidably inserted into the slideways.

[0027] By adopting the above technical solution, when the motor drives the lead screw to rotate, the nut can move up and down along the slideway on the wedge surface. When the nut moves upward, the first wedge block and the second wedge block are stretched apart, causing the angle between the first and second diagonal supports to increase. Conversely, when the nut moves downward, the angle between the first and second diagonal supports decreases. This effectively links the rotating assembly and the angle adjustment assembly, simplifies the structure, and reduces production and processing costs.

[0028] Optionally, the angle adjustment assembly further includes a tension spring, one end of which is connected to the first diagonal support, and the other end of which is connected to the second diagonal support.

[0029] By adopting the above technical solution, when the nut moves downward along the screw rod, the first wedge block and the second wedge block can return to their original positions under the action of the tension spring, so that the angle between the first diagonal support and the second diagonal support becomes smaller, thereby improving the efficiency of the angle adjustment process.

[0030] In a second aspect, the present application provides a method for constructing a tool for preventing deformation and twisting of a door-type wall panel, comprising the following steps:

[0031] S1: After the portal wall panel is demoulded, the ends of the horizontal steel pipe are respectively connected to the reserved bolts of the two vertical wall limbs of the portal wall panel. One end of the first diagonal brace and the second diagonal brace are respectively inserted into the grooves at the two ends of the horizontal steel pipe, and the baffles are used to limit them. The hinged ends of the first diagonal brace and the second diagonal brace are rotated and set on the bottom surface of the upper beam;

[0032] S2: Before hoisting, move the rotating block from the upper end of the screw rod along the slide groove to the upper end surface of the first wedge block and the second wedge block, and put the nut on the lower end of the screw rod thread segment;

[0033] S3: transport the door-type wall panel to the construction site. When the door-type wall panel is about to contact the positioning point, start the motor, take out the baffle, and drive the first diagonal brace and the second diagonal brace to rotate to a direction perpendicular to the horizontal steel pipe;

[0034] S4: Take the rotating block out from the upper end of the screw rod along the slide groove, start the motor again, adjust the angle between the first diagonal support and the second diagonal support so that the bottom of the first diagonal support and the second diagonal support can be supported on the horizontal plane, and then position it;

[0035] S5: After positioning is completed, the motor is started to rotate the first diagonal brace and the second diagonal brace again and away from the ground, and then the horizontal steel pipe, the first diagonal brace and the second diagonal brace are taken out of the door-type wall panel.

[0036] By adopting the above technical solution, before hoisting, a horizontal steel pipe is first set between the two vertical wall limbs of the portal wall panel, and then the first diagonal brace and the second diagonal brace are connected between the horizontal steel pipe and the upper beam to further enhance the connection force between the upper beam and the vertical wall limb. Starting the motor can drive the first diagonal brace and the second diagonal brace to rotate to a direction perpendicular to the horizontal steel pipe, so that the wall can be supported on the ground, which is convenient for the subsequent positioning process. After positioning, the horizontal steel pipe, the first diagonal brace and the second diagonal brace can be removed from the wall. Compared with the traditional construction method of integrally injection-molding the channel steel and the portal wall panel, the tooling in this application can be applied to portal wall panels of different sizes, and can produce different effects for various construction sections of portal wall panel hoisting, which can effectively improve construction efficiency.

[0037] In summary, this application has at least one of the following beneficial effects:

[0038] 1. The horizontal steel pipes and the door-type wall panels coordinate with each other and act as a frame, so that the connectors and the wall panels form a whole, which strengthens the connection of the wall panels and protects the integrity of the edge concrete of the wall panels during the stress process, which is conducive to improving the bearing capacity of the wall and making it difficult for the vertical wall limbs to twist and deform under their own gravity.

[0039] 2. The first diagonal brace and the second diagonal brace can connect the horizontal steel pipe with the upper beam, further sharing the vertical load of the vertical wall limbs and further improving the connection force between the vertical wall limbs and the upper beam; at the same time, the triangular structure formed by the first diagonal brace, the second diagonal brace and the horizontal steel pipe is stable and pressure-resistant, further strengthening the connection between the upper beam of the portal wall panel and the vertical wall limbs, and improving the bearing capacity of the wall.

[0040] 3. By adjusting the angle between the first diagonal brace and the second diagonal brace, as well as rotating and adjusting the length of the first diagonal brace and the second diagonal brace, and adjusting the length of the horizontal steel pipe, the entire tooling can be adapted to door-type wall panels of different sizes; at the same time, when not in use, the entire tooling can be shortened to a certain length for easy storage, storage and transportation.

[0041] 4. By starting the motor, the first and second diagonal braces can be rotated around the hinged ends to a direction perpendicular to the horizontal steel pipe, supporting the entire portal wall panel on the ground, facilitating the subsequent positioning process. By adjusting the position of the first and second diagonal braces, they can support the portal wall panel, improving the efficiency of the portal wall panel hoisting.

[0042] 5. The angle adjustment component can adjust the angle between the first diagonal brace and the second diagonal brace, so that the first diagonal brace and the second diagonal brace are placed on the ground more stably and support the wall panel; at the same time, the rotating component and the angle adjustment component are well linked, the structure is simple, and the production and processing costs are reduced.

DETAILED DESCRIPTION

[0048] The following is combined with Figure 1-3 This application is described in further detail.

[0049] The embodiment of the present application discloses a tool for preventing deformation and twisting of a door-type wall panel, referring to Figure 1 and Figure 2, including a horizontal steel pipe 1, a first diagonal brace 2, a second diagonal brace 3, a rotation assembly 4 and an angle adjustment assembly 5. The horizontal steel pipe 1, the first diagonal brace 2 and the second diagonal brace 3 together form a movable triangular structure. When in use, the horizontal steel pipe 1 is set between the two vertical wall limbs 61 of the door-type wall panel 6, the first diagonal brace 2 and the second diagonal brace 3 are hinged to each other, and the hinged ends of the first diagonal brace 2 and the second diagonal brace 3 are rotatably set on the mounting plate 8 of the upper beam 62 of the door-type wall panel 6. The ends of the first diagonal brace 2 and the second diagonal brace 3 away from the hinged ends are both detachably connected to the horizontal steel pipe 1. The rotation assembly 4 and the angle adjustment assembly 5 are both set between the first diagonal brace 2 and the second diagonal brace 3.

[0050] Reference Figure 1 The horizontal steel pipe 1 includes a main steel pipe 11 and a telescopic steel pipe 12. The main steel pipe 11 is a hollow structure. The telescopic steel pipe 12 is slidably inserted into the main steel pipe 11. The outer ring of the telescopic steel pipe 12 and the inner ring of the main steel pipe 11 are both threaded, so that the length of the horizontal steel pipe 1 can be adjusted by rotating the main steel pipe 11. Correspondingly, the first diagonal brace 2 includes a first main diagonal brace 21 and a first telescopic diagonal brace 22, and the second diagonal brace 3 includes a second main diagonal brace 31 and a second telescopic diagonal brace 32, and all adopt the same connection method as the horizontal steel pipe 1. This makes the tooling applicable to door-type wall panels 6 of different sizes. The two vertical wall limbs 61 of the door-type wall panel 6 are both provided with reserved bolts. The two ends of the horizontal steel pipe 1 are respectively connected to the reserved bolts on the two vertical wall limbs 61 in a plate-type manner, which facilitates the installation and disassembly of the horizontal steel pipe 1.

[0051] Reference Figure 1 The horizontal steel tube 1 has grooves 13 on both sides of the end near the vertical wall limb 61. The first diagonal brace 2 and the second diagonal brace 3 are respectively inserted into the two grooves 13 of the horizontal steel tube 1. Each groove 13 is provided with a baffle 7, which is used to limit the position of the first diagonal brace 2 or the second diagonal brace 3. Blocks 14 extend from the edges of each groove 13 to limit the position of the baffle 7, so that the baffle 7 and the corresponding first diagonal brace 2 or second diagonal brace 3 can be embedded in the groove 13.

[0052] Reference Figure 2 and Figure 3The rotating assembly 4 includes a motor 41, a screw rod 42 and a rotating block 43. The motor 41 is arranged in the middle of the horizontal steel pipe 1. One end of the screw rod 42 is connected to the output shaft of the motor 41. The screw rod 42 includes a threaded section 422 located near one end of the motor 41 and a smooth section 421 located above the threaded section 422. The rotating block 43 is sleeved outside the smooth section 421 of the screw rod 42. The rotating block 43 is in the shape of an inverted truncated cone. A sliding groove 4211 is provided on the outer surface of the smooth section 421 of the screw rod 42. A protrusion 431 is provided on the inner side of the rotating block 43. The protrusion 431 enables the rotating block 43 to move up and down along the sliding groove 4211 outside the smooth section 421 of the screw rod 42. When the motor 41 drives the screw rod 42 to rotate, since the rotating block 43 is in close contact with the screw rod 42, the rotating block 43 can rotate circumferentially along with the screw rod 42.

[0053] Reference Figure 3 and Figure 4 The angle adjustment assembly 5 includes a first wedge block 51, a second wedge block 52, and a nut 53. The first wedge block 51 and the second wedge block 52 are arranged on both sides of the screw rod 42, and the first wedge block 51 and the second wedge block 52 are connected to the corresponding first diagonal support 2 or second diagonal support 3 through a connecting rod 9. The upper end surfaces of the first wedge block 51 and the second wedge block 52 are arc-shaped to adapt to the outer surface shape of the truncated cone-shaped rotating block 43, so that the two sides of the rotating block 43 can be well fitted with the first wedge block 51 and the second wedge block 52 respectively. At the same time, the outer surface of the rotating block 43 has a bar-shaped gear. When the rotating block 43 rotates under the drive of the motor 41, the first wedge block 51 and the second wedge block 52 can rotate with the rotating block 43.

[0054] Reference Figure 3 and Figure 4 The nut 53 is threadably connected to the threaded section 422 of the lead screw 42. The nut 53 is positioned between the two wedge-shaped surfaces of the first wedge block 51 and the second wedge block 52. Slideways 55 are defined on the wedge surfaces of the first wedge block 51 and the second wedge block 52. The nut 53 has projections 531 on either side that slide into the slideways 55. When the lead screw 42 rotates under the drive of the motor 41, the nut 53 moves along the two wedge-shaped surfaces via the projections 531, allowing the first wedge block 51 and the second wedge block 52 to be pushed apart by the nut 53 to form different angles.

[0055] Reference Figure 1 and Figure 2The first wedge block 51 is fixedly connected to the first diagonal brace 2 via a connecting rod 9, and the second wedge block 52 is fixedly connected to the second diagonal brace 3 via a connecting rod 9. When the first wedge block 51 and the second wedge block 52 are stretched to a certain angle by the nut 53, the angle between the first diagonal brace 2 and the second diagonal brace 3 can be changed accordingly, thereby adapting to door-type wall panels 6 of different sizes. A tension spring 54 is also provided between the first diagonal brace 2 and the second diagonal brace 3. When the motor 41 drives the nut 53 to move downward along the screw rod 42, the angle between the first wedge block 51 and the second wedge block 52 by the nut 53 decreases, and the tension spring 54 can quickly reset the first wedge block 51 and the second wedge block 52.

[0056] The implementation principle of a tool for preventing deformation and twisting of a door-type wall panel according to an embodiment of the present application is as follows: a horizontal steel pipe 1, a first diagonal brace 2, and a second diagonal brace 3 together form a tool for connecting the upper beam 62 of the door-type wall panel 6 and the two vertical wall limbs 61. Before hoisting the door-type wall panel 6, the construction personnel first install the horizontal steel pipe 1 between the two vertical wall limbs 61, and then respectively connect the mutually hinged first diagonal brace 2 and the second diagonal brace 3 to the two ends of the horizontal steel pipe 1, and limit them with a baffle 7, and rotate the hinged ends of the first diagonal brace 2 and the second diagonal brace 3 to be set on the upper beam 62. Then, the rotating block 43 is inserted from the upper end of the screw rod 42 along the slide groove 4211, so that the rotating block 43 is tightly abutted against the first wedge block 51 and the second wedge block 52.

[0057] When hoisting the door-type wall panel 6 to the construction site, when the bottoms of the two vertical wall limbs 61 are about to contact the positioning ribs, the motor 41 is started, the nut 53 rises, and the drawstring 44 is pulled to pull the baffle 7 out of the groove 13. The first diagonal brace 2 and the second diagonal brace 3 can now be separated from the horizontal steel pipe 1. At the same time, driven by the rotation of the rotating block 43, the first diagonal brace 2 and the second diagonal brace 3 rotate with the hinged end as the fulcrum. When the first diagonal brace 2 and the second diagonal brace 3 rotate to a direction perpendicular to the horizontal steel pipe 1, the motor 41 is turned off, and the bottoms of the first diagonal brace 2 and the second diagonal brace 3 are fixed to the ground, thereby supporting the door-type wall panel 6 and facilitating the positioning of the door-type wall panel 6 with the positioning ribs. After positioning is completed, the horizontal steel pipe 1, the first diagonal brace 2 and the second diagonal brace 3 are removed from the entire door-type wall panel 6. The length of the horizontal steel pipe 1 can be adjusted by rotating the main steel pipe 11, and the length of the first diagonal brace 2 and the second diagonal brace 3 can be adjusted by rotating, so that the tooling can adapt to door-type wall panels 6 of different sizes.

[0058] When the angle between the first diagonal brace 2 and the second diagonal brace 3 needs to be slightly adjusted, the motor 41 is turned on and the rotating block 43 is removed from the upper end of the screw rod 42. At this time, the first diagonal brace 2 and the second diagonal brace 3 will not rotate. When the nut 53 moves between the first wedge block 51 and the second wedge block 52, the nut 53 can move along the first wedge surface and the second wedge surface, thereby changing the distance between the first wedge block 51 and the second wedge block 52, thereby changing the angle between the first diagonal brace 2 and the second diagonal brace 3.

[0059] The present application also discloses a construction method for the above-mentioned device, which comprises the following steps:

[0060] S1: After the door-type wall panel 6 is demoulded, the two ends of the horizontal steel pipe 1 are respectively connected to the reserved bolts of the two vertical wall limbs 61 of the door-type wall panel 6, and one end of the first diagonal brace 2 and the second diagonal brace 3 are respectively inserted into the grooves 13 at both ends of the horizontal steel pipe 1. The baffle 7 is used to limit them, and the hinged ends of the first diagonal brace 2 and the second diagonal brace 3 are rotated and set on the bottom surface of the upper beam 62;

[0061] S2: Before hoisting, move the rotating block 43 from the upper end of the screw rod 42 along the slide groove 4211 to the upper end surface of the first wedge block 51 and the second wedge block 52, and sleeve the nut 53 on the lower end of the threaded section 422 of the screw rod 42;

[0062] S3: transport the door-type wall panel 6 to the construction site. When the door-type wall panel 6 is about to contact the positioning point, start the motor 41, take out the baffle 7, and drive the first diagonal brace 2 and the second diagonal brace 3 to rotate to a direction perpendicular to the horizontal steel pipe 1;

[0063] S4: Take the rotating block 43 out from the upper end of the screw rod 42 along the slide groove 4211, start the motor 41 again, adjust the angle between the first diagonal support 2 and the second diagonal support 3 so that the bottom of the first diagonal support 2 and the second diagonal support 3 can be supported on the horizontal plane, and then position it;

[0064] S5: After positioning is completed, the motor 41 is started to rotate the first diagonal brace 2 and the second diagonal brace 3 again and away from the ground, and then the horizontal steel pipe 1, the first diagonal brace 2 and the second diagonal brace 3 are taken out of the door-type wall panel 6.

[0065] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
