Description

Technical Field

[0001] The invention relates to the technical field of plant engineering construction, and in particular to a wall panel hoisting tool and method. Background Art

[0002] In the existing wall panel hoisting, i.e. the hoisting of the extra-long composite vertical panels, a steel hoisting frame is usually set up to hoist the wall composite panels in order to prevent the composite panels from breaking during the hoisting process. Although the steel hoisting frame can protect the composite panels well during the hoisting process, the hoisting efficiency is too low due to the heavy weight of the hoisting frame. At the same time, the requirements for the crane are also high, and the construction period is often long. The foothold of the wall panel is set on the guide wall at the bottom of the wall. Before the wall panel is hoisted for construction, the guide wall at the bottom of the wall needs to be constructed first, but it is often affected by the guide wall and cannot well control the elevation and flatness.

[0003] However, for the wall panel project of the Tesla Super Factory project, the total wall area exceeds 30,000 square meters, and the absolute construction period of the overall construction is 30 days. However, the construction period is much longer than this requirement if the traditional lifting frame hoisting method is used.

[0004] Therefore, it is necessary to invent a wall panel hoisting tool and method to solve the shortcomings of the existing wall composite vertical panel hoisting process relying on the lifting frame and the wall bottom guide, low efficiency, long construction period, etc. Summary of the invention

[0013] Optionally, the hoisting tool further comprises a height adjustment device for adjusting the height of the bottom of the wall panel to be hoisted, and the height adjustment device is connected to a purlin fixed on the wall surface.

[0014] Optionally, the elevation adjustment device includes a second base, the second base is provided with a fifth slot for clamping the purlin, the bottom of the second base is connected to a fixing part for fixing the bottom of the wall panel to be hoisted, and the top of the second base is provided with a plurality of adjustment parts, and the second base can move up and down relative to the adjustment parts.

[0015] Optionally, the fixing member includes a connected horizontal portion and a vertical portion, the top of the vertical portion is connected to the bottom of the second base, and a first reinforcing plate is provided on the vertical portion.

[0016] Optionally, a second reinforcing plate is provided on the second base, and the second reinforcing plate is arranged around the second base.

[0017] In order to solve the above technical problems, the present invention also provides a method for hoisting a wall panel, the method comprising the following steps:

[0018] Fixing the hoisting fixture to the top of the wall panel to be hoisted, and installing a corner protector at the corners on both sides of the bottom of the wall panel to be hoisted;

[0019] The wall panel to be hoisted is erected along the short side direction to lift the panel;

[0020] After the wall panel to be hoisted is lifted vertically, the corner protector is removed;

[0021] Transporting the wall panel to be hoisted to the installation position on the wall, and installing the wall panel to be hoisted on the wall;

[0022] Removing the lifting fixture;

[0023] Repeat all the above steps until all wall panels are installed.

[0024] Optionally, when the wall panel to be hoisted is a header panel, a straightened verticality control device is pre-installed on the purlin at the to-be-installed position, and before the wall panel to be hoisted is installed on the wall, the hoisting method further includes:

[0025] Push one side of the wall panel to be hoisted onto the verticality control device.

[0026] Optionally, a height adjustment device is pre-installed on the bottom purlin at the to-be-installed position, and before the to-be-installed wall panel is installed on the wall, the hoisting method further includes:

[0027] The bottom of the wall panel to be hoisted is clamped into the elevation adjustment device, and the height of the bottom of the wall panel to be hoisted is adjusted by the elevation adjustment device.

[0028] Compared with the prior art, the wall panel hoisting tool and method provided by the present invention have the following advantages:

[0029] (1) The wall panel hoisting tool provided by the present invention includes a hoisting clamp and a corner protector; the hoisting clamp includes a clamping body and a lifting ring arranged at the top of the clamping body, the clamping body is provided with a first clamping groove for clamping the wall panel to be hoisted; the corner protector is provided with a second clamping groove that is clamped with the bottom corner of the wall panel to be hoisted. Thus, the hoisting clamp is installed on the top of the wall panel through the first clamping groove, and the corner protector is installed at the bottom corner of the wall panel to be hoisted through the second clamping groove, and the lifting ring is connected to the crane, so that the crane can start hoisting from the top of the wall panel first, thereby reducing the burden on the crane. The provision of the first clamping groove and the second clamping groove facilitates the installation of the hoisting clamp and the corner protector on the wall panel. During the hoisting process, the corner protector can effectively protect the bottom corner of the wall panel and improve the construction quality. By cooperating with the hoisting fixture and the corner protector, the hoisting implementation process of the wall panel is simple and easy, the hoisting efficiency of the wall panel is improved, and the construction period is effectively saved. At the same time, the hoisting tool has a simple structure and saves costs.

[0030] (2) The wall panel hoisting tool provided by the present invention has a buckle in the second clamping groove for clamping the wall panel to be hoisted. Thus, the buckle matches the edges of the long sides of the wall panel, which can not only clamp the wall panel, but also prevent the bottom of the second clamping groove from directly contacting the edge of the wall panel, thereby facilitating the protection of the edge structure of the wall panel.

[0031] (3) The wall panel hoisting tool provided by the present invention is provided with a plurality of first mounting holes on the groove wall on one side of the first slot, and a plurality of second mounting holes corresponding to the first mounting holes on the groove wall on the other side. Therefore, after the hoisting fixture is installed on the top of the wall panel, holes are punched on the wall panel at positions corresponding to the first mounting holes and the second mounting holes, so that the hoisting fixture can be fixed to the wall panel by pin screws, making the installation of the hoisting fixture more reliable.

[0032] (4) The hoisting tool provided by the present invention also includes a verticality control device for controlling the verticality of the wall panel to be hoisted, and the verticality control device is connected to the purlin fixed on the wall. Therefore, the verticality control device is conducive to ensuring that the wall panel can be installed vertically on the wall. The verticality control device is fixed on the purlin of the wall in advance and is straightened by a theodolite or other straightening instrument, so as to achieve the purpose of controlling the verticality of the wall panel. The verticality control device includes a first base, and the first base is provided with a third clamping groove for clamping the first purlin. Therefore, the verticality control device can be effectively fixed to the purlin of the wall through the third clamping groove. By providing a wide plate on the side of the first base away from the wall, a fourth clamping groove for clamping the wall panel to be hoisted is formed between the wide plate, the first base and the purlin. Therefore, the wide plate is adjusted to be vertical by a straightening instrument such as a theodolite, so that when the wall panel is pushed into the fourth clamping groove, the wall panel can be ensured to be vertical, thereby controlling the verticality of the wall panel.

[0033] (5) The hoisting tool provided by the present invention also includes a height adjustment device for adjusting the height of the bottom of the wall panel to be hoisted, and the height adjustment device is connected to the purlin fixed on the wall. Therefore, the arrangement of the height adjustment device is conducive to controlling the flatness of the bottom of each wall panel and improving the quality of construction. The height adjustment device includes a second base, and the second base is provided with a fifth clamping groove for clamping the purlin. Therefore, the height adjustment device can be effectively fixed to the purlin on the wall through the fifth clamping groove, so that the height of the bottom of each wall panel can be controlled by moving the height adjustment device up and down. In addition, since the bottom of the second base is connected with a fixing member for fixing the bottom of the wall panel to be hoisted, the top of the second base is provided with a plurality of adjusting members, and the second base can move up and down relative to the adjusting members. Therefore, the wall panel hoisted by the crane can be supported by the fixing member, and the height of the bottom of the wall panel can be adjusted by moving the adjusting member up and down, so as to achieve the purpose of adjusting the height of the bottom of the wall panel and controlling the flatness of the bottom of each wall panel. In addition, by setting up the elevation adjustment device, the wall panel hoisting can be carried out before the guide wall construction at the bottom of the wall, avoiding the influence of the guide wall on the wall panel construction.

[0034] (6) Since the fixing member includes a connected horizontal portion and a vertical portion, the top of the vertical portion is connected to the bottom of the second base, so that the horizontal portion can effectively support the wall panel, and the vertical portion can play a role in connecting the second base and the horizontal portion, and the vertical portion allows a proper height difference to be left between the bottom of the wall panel and the purlin at the bottom of the wall surface to be installed, which is more conducive to controlling the height of the bottom of the wall panel so that the bottoms of the wall panels are flush with each other. By providing a first reinforcing plate on the vertical portion and a second reinforcing plate on the second base, and the second reinforcing plate is arranged around the second base, the first reinforcing plate and the second reinforcing plate can effectively strengthen the rigidity of the fixing member and the second base, avoid the fixing member and the second base from breaking, and improve the reliability of the elevation adjustment device.

[0035] (7) The wall panel hoisting method provided by the present invention comprises the following steps: fixing a hoisting fixture to the top of the wall panel to be hoisted, and installing a corner protector at the corners on both sides of the bottom of the wall panel to be hoisted; erecting the wall panel to be hoisted along the short side direction to lift the panel; after the wall panel to be hoisted is vertically hoisted, removing the corner protector; transporting the wall panel to be hoisted to the installation position of the wall surface, and installing the wall panel to be hoisted on the wall surface; removing the hoisting fixture; repeating all the above steps until all the wall panels are hoisted. Therefore, the method makes the hoisting implementation process of the wall panel simple and easy by cooperating with the hoisting fixture and the corner protector, improves the hoisting efficiency of the wall panel, effectively saves construction time, and improves the construction quality. In addition, the method enables the crane to start hoisting from the top of the wall panel, using the corner protector as a support point, thereby reducing the burden on the crane.

[0036] (8) When the wall panel to be hoisted is a head panel, before the wall panel to be hoisted is installed on the wall, the hoisting method of the wall panel provided by the present invention further includes: pushing one side of the wall panel to be hoisted into a verticality control device pre-installed and straightened on the purlin of the wall. Thus, this step ensures that the wall panel is vertical and controls the verticality of the wall panel.

[0037] (9) Since a height adjustment device is pre-installed on the purlin at the bottom of the installation position, before the wall panel to be hoisted is installed on the wall, the hoisting method further includes: inserting the bottom of the wall panel to be hoisted into the height adjustment device, and adjusting the height of the bottom of the wall panel to be hoisted by the height adjustment device. Thus, the height of the bottom of the wall panel can be adjusted through this step, thereby controlling the flatness of the bottom of each wall panel and improving the quality of construction. In addition, the hoisting of the wall panel can be carried out before the guide wall construction at the bottom of the wall, thereby avoiding the influence of the guide wall on the construction of the wall panel.

[0056] like Figures 1 to 8 As shown, the lifting tool for the wall panel 500 provided in this embodiment includes a lifting clamp 100 and a corner protector 200; the lifting clamp 100 is used to clamp the top of the wall panel 500 to be lifted, and the lifting clamp 100 includes a clamping body 110 and a lifting ring 120 arranged on the top of the clamping body 110, and the clamping body 110 is provided with a first clamping groove 111 for clamping the wall panel 500 to be lifted; the corner protector 200 is used to be installed at the bottom corner of the wall panel 500 to be lifted, and the corner protector 200 is provided with a second clamping groove 210 that is clamped with the bottom corner of the wall panel 500 to be lifted. Thus, the hoisting fixture 100 is installed on the top of the wall panel 500 through the first slot 111, the corner protector 200 is installed on the bottom corner of the wall panel 500 to be hoisted through the second slot 210, and the lifting ring 120 is connected to the lifting rope 700 of the crane, so that the crane can be used to start hoisting from the top of the wall panel 500, and the corner protector 200 is used as a support point, which reduces the burden of the crane. The first slot 111 and the second slot 210 are provided to facilitate the installation of the hoisting fixture 100 and the corner protector 200 on the wall panel 500. During the hoisting process, the corner protector 200 can effectively protect the bottom corner of the wall panel 500 and improve the construction quality. Through the cooperation of the hoisting fixture 100 and the corner protector 200, the hoisting implementation process of the wall panel 500 is simple and easy, the hoisting efficiency of the wall panel 500 is improved, and the construction period is effectively saved. At the same time, the hoisting tool has a simple structure and saves costs.

[0057] Preferably, a buckle 220 for clamping the wall panel 500 to be hoisted is provided in the second clamping slot 210. Thus, the buckle 220 matches the edges of the long sides of the wall panel 500, which can not only clamp the wall panel 500, but also prevent the bottom of the second clamping slot 210 from directly contacting the edge of the wall panel 500, thereby protecting the edge structure of the wall panel 500. It should be noted that the external structure of the second clamping slot 210, that is, the external shape and structure of the corner protector 200 are not specifically limited in the present invention; the specific structure and shape of the buckle 220 can be set according to the edge structures on both sides of the wall panel 500 to be hoisted, and the present invention does not limit the specific structure of the buckle 220.

[0058] More preferably, the pair of corner protectors 200 provided in this embodiment are provided with two different buckles 220 inside, and the two different buckles 220 are matched with the edge structures on both sides of the long side of the wall panel 500 to be hoisted, and a filler 221 is provided between the buckle 220 and the bottom of the second slot 210, and the filler 221 is preferably made of a flexible material, thereby being able to play a more effective buffering role on the edge structure of the wall panel 500. It should be noted that each wall panel 500 is spliced ​​together for installation, so the buckle 220 inside the corner protector 200 is divided into a male buckle and a female buckle to correspond to the spliced ​​structure on both sides of the wall panel 500.

[0059] Preferably, a plurality of first mounting holes 112 are provided on the slot wall on one side of the first slot 111, and a plurality of first mounting holes 113 are provided on the slot wall on the other side corresponding to the first mounting holes 112. Thus, after the hoisting fixture 100 is installed on the top of the wall panel 500, holes are punched on the wall panel 500 at positions corresponding to the first mounting holes 112 and the first mounting holes 113, so that the hoisting fixture 100 can be fixed to the wall panel 500 by means of pin screws, thereby making the installation of the hoisting fixture 100 more reliable.

[0060] Preferably, the hoisting tool further comprises a verticality control device 300 for controlling the verticality of the wall panel 500 to be hoisted, and the verticality control device 300 is connected to the purlin 600 fixed on the wall. Thus, the verticality control device 300 is helpful to ensure that the wall panel 500 can be installed vertically on the wall. The verticality control device 300 is fixed on the purlin 600 of the wall in advance and is aligned with an alignment instrument such as a theodolite. When installing the head plate of the wall panel 500, the wall panel 500 is pushed into the verticality control device 300, thereby achieving the purpose of controlling the verticality of the wall panel 500.

[0061] It should be noted that, in the present embodiment, the verticality control device 300 is often fixed on the purlin 600 in advance when the head board is started, and the wall panel 500 to be hoisted thereafter is generally controlled in verticality by being joined together with one side of the previously hoisted wall panel 500. However, the present invention does not make any specific limitation on the use and installation position of the verticality. The verticality control device 300 is used when hoisting each wall panel 500, which is also within the protection scope of the present invention.

[0062] Preferably, the verticality control device 300 includes a first base 310, a third clamping groove 311 for clamping the first purlin 600 is provided on the first base 310, a wide plate 320 is provided on the side of the first base 310 away from the wall, and a fourth clamping groove for clamping the wall panel 500 to be hoisted is formed between the wide plate 320, the first base 310 and the purlin 600. Therefore, the verticality control device 300 can be effectively fixed on the purlin 600 of the wall through the third clamping groove 311, and the wide plates 320 of each verticality control device are adjusted to be on a vertical line through the theodolite, so that when the wall panel 500 is pushed into the fourth clamping groove, the wall panel 500 can be ensured to be vertical, and the verticality of the wall panel 500 is controlled.

[0063] Preferably, the verticality control device 300 in this embodiment is a hollow structure, connected by four connecting plates, including two parallel long plates, a wide plate 320 perpendicular to the two long plates and arranged at one end of the long plates, and a short plate arranged at the other end of the long plates, and a bayonet is provided on each of the two long plates, and the two long plates are combined to form the third bayonet 311 through the bayonet. Therefore, the structure of the verticality control device 300 can effectively save materials, and at the same time, it can ensure that the rigidity of the verticality control device 300 meets the requirements. It should be noted that, since the main function of the verticality control device 300 is to control the verticality of the wall panel 500, and not to fix the wall panel 500 on the wall, the rigidity requirement of the verticality control device 300 is not strict, and the structure of the verticality control device 300 described above can fully meet the requirements; when in use, the verticality control device 300 is installed on each of the two purlins 600 of the wall in advance to effectively control the verticality of the wall panel 500.

[0064] Preferably, the hoisting tool further comprises a height adjustment device 400 for adjusting the height of the bottom of the wall panel 500 to be hoisted, and the height adjustment device 400 is connected to the purlin 600 fixed on the wall. Thus, the height adjustment device 400 is provided to help control the flatness of the bottom of each wall panel 500 and improve the quality of construction. It should be noted that, when in use, the height adjustment device 400 is adjusted based on the bottom height of the previous wall panel 500 or the construction line, or is assisted by a straightening instrument such as a theodolite.

[0065] Preferably, the elevation adjustment device 400 includes a second base 410, a fifth clamping groove 411 for clamping the purlin 600 is provided on the second base 410, a fixing member 430 for fixing the bottom of the wall panel 500 to be hoisted is connected to the bottom of the second base 410, and a plurality of adjusting members 412 are provided on the top of the second base 410, and the second base 410 can move up and down relative to the adjusting members 412. Therefore, the elevation adjustment device 400 can be effectively fixed to the purlin 600 on the wall through the fifth clamping groove 411, so that the height of the bottom of each wall panel 500 can be controlled by moving the elevation adjustment device 400 up and down. Therefore, the wall panel 500 hoisted by the crane is supported by the fixing member 430, and the elevation adjustment device 400 is moved up and down by the adjusting member 412, so as to achieve the purpose of adjusting the height of the bottom of the wall panel 500 and controlling the flatness of the bottom of each wall panel 500. In addition, by providing the elevation adjustment device 400 , the wall panel 500 can be hoisted and installed before the guide wall construction at the bottom of the wall, thereby avoiding the influence of the guide wall on the construction of the wall panel 500 .

[0066] More preferably, the elevation adjustment device is fixed on the purlin closest to the guide wall to be constructed, thereby facilitating the control of the construction height of the guide wall and the room body.

[0067] Preferably, the fixing member 430 includes a connected horizontal portion 432 and a vertical portion 431, the top of the vertical portion 431 is connected to the bottom of the second base 410, and a first reinforcing plate 433 is provided on the vertical portion 431. Thus, the wall panel 500 can be effectively supported by the horizontal portion 432, and the second base 410 and the horizontal portion 432 can be connected by the vertical portion 431. Moreover, the vertical portion 431 allows a proper height difference between the bottom of the wall panel 500 and the purlin 600 at the bottom of the wall surface, which is more conducive to controlling the height of the bottom of the wall panel 500 so that the bottoms of the wall panels 500 are flush with each other.

[0075] Corresponding to the above-mentioned wall panel hoisting tool, the present invention also provides a wall panel hoisting method. Please refer to Figure 9, which schematically shows a flow chart of the wall panel hoisting method provided by an embodiment of the present invention. Fig. 9 As shown, the method comprises the following steps:

[0076] Step S1, fixing a hoisting fixture to the top of the wall panel to be hoisted, and installing a corner protector at the corners on both sides of the bottom of the wall panel to be hoisted;

[0077] Step S2, erecting the wall panel to be hoisted along the short side direction to lift the panel;

[0078] Step S3, after the wall panel to be hoisted is vertically hoisted, the corner protector is removed;

[0079] Step S4, transporting the wall panel to be hoisted to the installation position on the wall, and installing the wall panel to be hoisted on the wall;

[0080] Step S5, removing the lifting fixture.

[0081] Repeat the above steps S1 to S5 until all wall panels are hoisted.

[0082] Thus, the method makes the lifting and implementation process of the wall panel simple and easy by cooperating with the lifting fixture and the corner protector, improves the lifting efficiency of the wall panel, effectively saves the construction period, and improves the construction quality. In addition, the method enables the crane to start lifting from the top of the wall panel, using the corner protector as a support point, thereby reducing the burden on the crane.

[0083] It should be noted that the lifting clamp and the corner protector can refer to the lifting tool of the present invention as described above; during the entire lifting process of the wall panel, the lifting clamp must always be connected to the lifting rope of the crane, and the crane must be kept running at all times to keep the wall panel in a suspended state, and the lifting clamp will not be removed until the current wall panel is installed; the corner protector is installed at the bottom corner of the wall panel by means of straps.

[0084] Preferably, step S2 specifically includes: firstly, the short side of the wall panel is erected vertically with the help of a crane and a user, so that one of the pair of pre-installed corner protectors is the fulcrum, the top of the wall panel is slowly lifted with the help of a crane, and the wall panel is controlled to prevent a large-scale twist with the help of a user. Thus, the fulcrum surface between the wall panel and the ground is reduced, and the burden of the crane is reduced according to the principle of leverage.

[0085] Preferably, when the wall panel to be hoisted is a head panel, a straightened verticality control device is pre-installed on the purlin at the installation position, and before the wall panel to be hoisted is installed on the wall, the hoisting method further comprises: pushing one side of the wall panel to be hoisted onto the verticality control device. Thus, the verticality of the wall panel is ensured and the verticality of the wall panel is controlled through this step.

[0086] Preferably, the verticality control device is installed on at least two purlins on the wall, thereby being able to more effectively control the verticality of the wall panel. It should be noted that the verticality control device can refer to the verticality control device of the present invention as described above; the present invention does not specifically limit the number of installations of the verticality control device.

[0087] Preferably, a height adjustment device is pre-installed on the purlin at the bottom of the installation position. Before installing the wall panel to be hoisted on the wall, the hoisting method further includes: inserting the bottom of the wall panel to be hoisted into the height adjustment device, and adjusting the height of the bottom of the wall panel to be hoisted by the height adjustment device. Thus, the height of the bottom of the wall panel can be adjusted through this step, thereby controlling the flatness of the bottom of each wall panel and improving the quality of construction. In addition, the hoisting of the wall panel can be carried out before the guide wall construction at the bottom of the wall, avoiding the influence of the guide wall on the construction of the wall panel.

[0088] It should be noted that the elevation adjustment device can refer to the elevation adjustment device of the present invention as described above; preferably, the elevation adjustment device is used for adjustment when each wall panel is installed; after the wall panel is installed, the bottom guide wall can be constructed so that the bottom of the wall panel is on the guide wall.

[0089] In summary, compared with the prior art, the wall panel hoisting tool and method provided by the present invention have the following advantages:

[0090] (1) The wall panel hoisting tool provided by the present invention includes a hoisting fixture and a corner protector; the hoisting fixture includes a clamping body and a lifting ring arranged at the top of the clamping body, the clamping body is provided with a first clamping groove for clamping the wall panel to be hoisted; the corner protector is provided with a second clamping groove that is clamped with the bottom corner of the wall panel to be hoisted. Thus, the hoisting fixture is installed on the top of the wall panel through the first clamping groove, and the corner protector is installed at the bottom corner of the wall panel to be hoisted through the second clamping groove, and the lifting ring is connected to the crane, so that the crane can start hoisting from the top of the wall panel first, thereby reducing the burden on the crane. The provision of the first clamping groove and the second clamping groove makes it easy to install the hoisting fixture and the corner protector on the wall panel, which is more conducive to the hoisting process of the wall panel. During the hoisting process, the corner protector can effectively protect the bottom corner of the wall panel and improve the construction quality. By cooperating with the hoisting fixture and the corner protector, the hoisting implementation process of the wall panel is simple and easy, the hoisting efficiency of the wall panel is improved, and the construction period is effectively saved. At the same time, the hoisting tool has a simple structure and saves costs.

[0091] (2) The wall panel hoisting tool provided by the present invention has a buckle in the second clamping groove for clamping the wall panel to be hoisted. Thus, the buckle matches the edges of the long sides of the wall panel, which can not only clamp the wall panel, but also prevent the bottom of the second clamping groove from directly contacting the edge of the wall panel, thereby facilitating the protection of the edge structure of the wall panel.

[0092] (3) The wall panel hoisting tool provided by the present invention is provided with a plurality of first mounting holes on the groove wall on one side of the first slot, and a plurality of second mounting holes corresponding to the first mounting holes on the groove wall on the other side. Therefore, after the hoisting fixture is installed on the top of the wall panel, holes are punched on the wall panel at positions corresponding to the first mounting holes and the second mounting holes, so that the hoisting fixture can be fixed to the wall panel by pin screws, making the installation of the hoisting fixture more reliable.

[0093] (4) The hoisting tool provided by the present invention also includes a verticality control device for controlling the verticality of the wall panel to be hoisted, and the verticality control device is connected to the purlin fixed on the wall. Therefore, the verticality control device is conducive to ensuring that the wall panel can be installed vertically on the wall. The verticality control device is fixed on the purlin of the wall in advance and is straightened by a theodolite or other straightening instrument, so as to achieve the purpose of controlling the verticality of the wall panel. The verticality control device includes a first base, and the first base is provided with a third clamping groove for clamping the first purlin. Therefore, the verticality control device can be effectively fixed to the purlin of the wall through the third clamping groove. By providing a wide plate on the side of the first base away from the wall, a fourth clamping groove for clamping the wall panel to be hoisted is formed between the wide plate, the first base and the purlin. Therefore, the wide plate is adjusted to be vertical by a straightening instrument such as a theodolite, so that when the wall panel is pushed into the fourth clamping groove, the wall panel can be ensured to be vertical, thereby controlling the verticality of the wall panel.

[0094] (5) The hoisting tool provided by the present invention also includes a height adjustment device for adjusting the height of the bottom of the wall panel to be hoisted, and the height adjustment device is connected to the purlin fixed on the wall. Therefore, the arrangement of the height adjustment device is conducive to controlling the flatness of the bottom of each wall panel and improving the quality of construction. The height adjustment device includes a second base, and the second base is provided with a fifth clamping groove for clamping the purlin. Therefore, the height adjustment device can be effectively fixed to the purlin on the wall through the fifth clamping groove, so that the height of the bottom of each wall panel can be controlled by moving the height adjustment device up and down. In addition, since the bottom of the second base is connected with a fixing member for fixing the bottom of the wall panel to be hoisted, the top of the second base is provided with a plurality of adjusting members, and the second base can move up and down relative to the adjusting members. Therefore, the wall panel hoisted by the crane can be supported by the fixing member, and the height of the bottom of the wall panel can be adjusted by moving the adjusting member up and down, so as to achieve the purpose of adjusting the height of the bottom of the wall panel and controlling the flatness of the bottom of each wall panel. In addition, by setting up the elevation adjustment device, the wall panel hoisting can be carried out before the guide wall construction at the bottom of the wall, avoiding the influence of the guide wall on the wall panel construction.

[0095] (6) Since the fixing member includes a connected horizontal portion and a vertical portion, the top of the vertical portion is connected to the bottom of the second base, so that the horizontal portion can effectively support the wall panel, and the vertical portion can play a role in connecting the second base and the horizontal portion, and the vertical portion allows a proper height difference to be left between the bottom of the wall panel and the purlin at the bottom of the wall surface to be installed, which is more conducive to controlling the height of the bottom of the wall panel so that the bottoms of the wall panels are flush with each other. By providing a first reinforcing plate on the vertical portion and a second reinforcing plate on the second base, the second reinforcing plate is arranged around the second base, so that the first reinforcing plate and the second reinforcing plate can effectively strengthen the rigidity of the vertical portion and the second base, avoid the vertical portion and the second base from breaking, and improve the reliability of the elevation adjustment device.

[0096] (7) The wall panel hoisting method provided by the present invention comprises the following steps: fixing a hoisting fixture to the top of the wall panel to be hoisted, and installing a corner protector at the corners on both sides of the bottom of the wall panel to be hoisted; erecting the wall panel to be hoisted along the short side direction to lift the panel; after the wall panel to be hoisted is vertically hoisted, removing the corner protector; transporting the wall panel to be hoisted to the installation position of the wall surface, and installing the wall panel to be hoisted on the wall surface; removing the hoisting fixture; repeating all the above steps until all the wall panels are hoisted. Therefore, the method makes the hoisting implementation process of the wall panel simple and easy by cooperating with the hoisting fixture and the corner protector, improves the hoisting efficiency of the wall panel, effectively saves construction time, and improves the construction quality. In addition, the method enables the crane to start hoisting from the top of the wall panel, using the corner protector as a support point, thereby reducing the burden on the crane.

[0097] (8) When the wall panel to be hoisted is a head panel, before the wall panel to be hoisted is installed on the wall, the hoisting method of the wall panel provided by the present invention further includes: pushing one side of the wall panel to be hoisted into a verticality control device pre-installed and straightened on the purlin of the wall. Thus, this step ensures that the wall panel is vertical and controls the verticality of the wall panel.

[0098] (9) Since a height adjustment device is pre-installed on the bottom purlin at the position to be installed, before the wall panel to be installed is installed on the wall, the installation method further includes:

[0099] The bottom of the wall panel to be hoisted is clamped into the elevation adjustment device, and the height of the bottom of the wall panel to be hoisted is adjusted by the elevation adjustment device. Thus, the height of the bottom of the wall panel can be adjusted through this step, so as to control the flatness of the bottom of each wall panel and improve the quality of construction. In addition, the hoisting of the wall panel can be carried out before the guide wall construction at the bottom of the wall surface, so as to avoid the influence of the guide wall on the construction of the wall panel.

[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
