Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, specifically to verticality correction technology for prefabricated shear walls. Background Technology

[0002] During the installation of prefabricated shear walls, the verticality error of the prefabricated shear walls will directly affect the quality of the project. Therefore, verticality correction is an essential construction step. Currently, the verticality correction of prefabricated shear walls is usually done manually, using a combination of tools such as mechanical wrenches, levels, tape measures, and plumb bobs. This involves repeated verticality measurement and adjustment, which is labor-intensive, inefficient, and makes it difficult to effectively control the verticality error.

[0003] Chinese Patent Publication No. CN 206319631 U discloses a shear wall vertical adjustment device, including a shear wall body and a vertical adjustment device body. The vertical adjustment device body includes columns, connectors, and support rods. Multiple horizontal columns are welded to the side wall of the shear wall body. Two or more horizontal columns are vertically connected to the columns. The support rods include a first support rod and a second support rod. The first support rod includes an adjustment device for adjusting the length of the first support rod. The second support rod includes an adjustment device for adjusting the length of the second support rod. Multiple horizontal columns are arranged horizontally on the side wall of the shear wall body, and the columns are vertically connected to the horizontal columns. The angle between the columns and the horizontal plane is adjusted by the length adjustment device on the support rod, thereby adjusting the verticality of the shear wall.

[0004] However, although the shear wall vertical adjustment device provided by the above solution reduces labor intensity to some extent, it still requires repeated manual adjustment, which is inefficient and cannot effectively guarantee the vertical accuracy of the shear wall.

[0005] Therefore, how to effectively improve the verticality correction efficiency of prefabricated shear walls and accurately control verticality errors to improve verticality accuracy has become an urgent problem to be solved in this field. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a prefabricated shear wall verticality correction device and construction method that is highly efficient, has low labor intensity, and can accurately control verticality error.

[0007] To achieve the above objectives, the present invention provides a prefabricated shear wall verticality correction device, used in conjunction with a prefabricated shear wall, including...

[0008] Horizontal support steel pipes are horizontally distributed, with the first end located in the lower region of the prefabricated shear wall and the second end connected to the floor slab embedded parts.

[0009] An inclined adjustable support steel pipe is provided, with one end of which is installed in the upper area of ​​the prefabricated shear wall via an adjustable connector, and the other end of which is installed at the second end of the horizontal support steel pipe via an adjustable connector and connected to the floor slab embedded parts.

[0010] A distance measuring device is installed in the area of ​​the embedded parts in the floor slab. It is configured to measure in real time the horizontal distance x and the oblique distance y between the center of the measuring device and the prefabricated shear wall, as well as the angle α between the horizontal distance x and the oblique distance y. The horizontal distance x and the oblique distance y are parallel to the horizontal support steel pipe and the oblique adjusting support steel pipe, respectively.

[0011] A vertical adjustment device is provided, which is connected to the distance measuring device and the inclined adjustment support steel pipe. The device is configured to process the measurement data acquired by the distance measuring device in real time, obtain the verticality deviation of the prefabricated shear wall, and adjust the length of the inclined adjustment support steel pipe in real time according to the verticality deviation.

[0012] Furthermore, the ranging device includes a laser rangefinder, which is configured to emit horizontal and oblique lasers at the prefabricated shear wall, the horizontal and oblique lasers being parallel to the horizontal support steel pipe and the oblique adjusting support steel pipe, respectively.

[0013] Furthermore, the laser rangefinder is equipped with a leveling bracket at its bottom.

[0014] Furthermore, the sag adjustment device is located in the second end region of the horizontal support steel pipe, and includes a housing, a support rod and a reaction bracket located at the bottom of the housing for cooperating with the horizontal support steel pipe, and a steel pipe clamping device located at the top of the housing for cooperating with the inclined adjustment support steel pipe.

[0015] Furthermore, the housing contains an industrial control computer, a power system connected to the industrial control computer, and an output gear connected to the power system. The industrial control computer is configured to drive the power system to move the output gear.

[0016] Furthermore, the steel pipe clamping device includes a steel pipe connector and a transmission gear disposed on the steel pipe connector. The steel pipe connector clamps the inclined adjusting support steel pipe, and the transmission gear meshes with the output gear.

[0017] Furthermore, the adjustable connector and the inclined adjustable support steel pipe are configured to be threadedly connected.

[0018] Furthermore, the support rod and the reaction bracket are respectively disposed at both ends of the housing, and the reaction bracket clamps the horizontal support steel pipe.

[0019] To achieve the above objectives, the present invention provides a prefabricated shear wall verticality correction construction method, based on the prefabricated shear wall verticality correction equipment, the construction method comprising:

[0020] Connect the horizontal support steel pipe to the prefabricated shear wall and the floor slab embedded parts, and connect the inclined adjustment support steel pipe to the prefabricated shear wall and the floor slab embedded parts respectively through adjustable connectors. Adjust the leveling distance measuring device and install the plumb adjustment device.

[0021] The distance measuring device measures the horizontal distance x and the oblique distance y between the center of the distance measuring device and the prefabricated shear wall in real time, as well as the angle α between the horizontal distance x and the oblique distance y, and ensures that the horizontal distance x and the oblique distance y are parallel to the horizontal support steel pipe and the oblique adjustment support steel pipe, respectively, and transmits the measurement data to the vertical adjustment device in real time.

[0022] The vertical adjustment device receives measurement data in real time and processes the data to obtain the vertical oblique distance y. x To obtain the verticality deviation of the prefabricated shear wall, the verticality deviation includes the measured deviation distance Δy, the vertical deviation angle δ of the prefabricated shear wall 500, the oblique deviation distance Δl of the inclined adjustment support steel pipe 300, and the adjustment angle θ, wherein...

[0023] y x =x / cos α,

[0024] Δy=|y x -y|,

[0025]

[0026]

[0027] θ = 360Δl / s

[0028] In the formula, Z is the height of the prefabricated shear wall, β is the angle between the inclined adjustable support steel pipe and the horizontal direction, h is the vertical height at the connection between the two ends of the inclined adjustable support steel pipe, and s is the pitch of the adjustable connector.

[0029] The output gear in the sag adjustment device rotates to adjust the sag angle θ, thereby adjusting the elongation or shortening of the oblique deviation distance Δl of the inclined adjustment support steel pipe.

[0030] Furthermore, if the vertical oblique distance y x If the oblique distance y is greater than the oblique distance y, the vertical adjustment device adjusts the oblique deviation distance Δl of the oblique adjustment support steel pipe. If the oblique distance y is perpendicular to the vertical distance y, the vertical deviation distance is greater than the vertical deviation distance Δl. x If the oblique distance y is less than the oblique distance, the sag adjustment device adjusts the oblique adjustment support steel pipe to shorten the oblique deviation distance Δl.

[0031] The prefabricated shear wall verticality correction device and construction method provided by this invention connects the prefabricated shear wall to horizontal support steel pipes and inclined adjustment support steel pipes, forming a triangular distribution. A ranging device measures the horizontal and inclined distances from the center of the ranging device to the prefabricated shear wall, as well as the angle between the horizontal and inclined distances. The horizontal and inclined distances are parallel to the horizontal and inclined adjustment support steel pipes, respectively, allowing the ranging device to measure the distribution angle of the horizontal and inclined adjustment support steel pipes. Since the horizontal support steel pipes are horizontally distributed, the verticality of the prefabricated shear wall can be corrected by adjusting the length of the inclined adjustment support steel pipes based on trigonometric functions.

[0032] Furthermore, this invention employs a plumb bob device to process the horizontal distance, oblique distance, and included angle in real time to obtain the verticality deviation of the prefabricated shear wall. Based on the verticality deviation, the length of the oblique adjustment support steel pipe is adjusted in real time to correct the verticality of the prefabricated shear wall, thereby accurately controlling the verticality error of the prefabricated shear wall. Real-time correction can be achieved through the cooperation of the distance measuring device and the plumb bob device, eliminating the need for repeated manual operation, resulting in high correction efficiency and low labor intensity.

[0045] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0046] See Figure 1 The image shows an example of the prefabricated shear wall verticality correction device provided by the present invention.

[0047] As shown in the figure, the prefabricated shear wall verticality correction device in this example is used in conjunction with the prefabricated shear wall 500 and mainly includes a distance measuring device 100, a vertical adjustment device 200, an inclined adjustment support steel pipe 300, and a horizontal support steel pipe 400.

[0048] The horizontal support steel pipes 400 are horizontally distributed, with the first end 410 located in the lower region of the prefabricated shear wall 500. One end of the inclined adjustment support steel pipe 300 is located in the upper region of the prefabricated shear wall 500, and the other end is connected to the second end 120 of the horizontal support steel pipe 400. This allows the inclined adjustment support steel pipe 300 and the horizontal support steel pipe 400 to form a triangular distribution with the prefabricated shear wall 500. By adjusting the length of the inclined adjustment support steel pipe 300, the verticality of the prefabricated shear wall 500 can be corrected.

[0049] Meanwhile, the ranging device 100 is configured to measure in real time the horizontal distance x and the oblique distance y between the center of the ranging device 100 and the prefabricated shear wall 500, as well as the angle α between the horizontal distance x and the oblique distance y. The horizontal distance x and the oblique distance y are parallel to the horizontal support steel pipe 400 and the oblique adjustment support steel pipe 300, respectively, so that the ranging device 100 can measure the distribution angle of the horizontal support steel pipe 400 and the oblique adjustment support steel pipe 300 in real time, thereby providing measurement data for adjusting the length of the oblique adjustment support steel pipe 300.

[0050] Furthermore, the vertical adjustment device 200 is connected to the distance measuring device 100 and the inclined adjustment support steel pipe 300, and is configured to process the measurement data acquired by the distance measuring device 100 in real time, obtain the verticality deviation of the prefabricated shear wall 500, and adjust the length of the inclined adjustment support steel pipe 300 in real time according to the verticality deviation, thereby correcting the verticality of the prefabricated shear wall 500, accurately controlling the vertical error, improving the correction efficiency, and reducing labor intensity.

[0051] Combination Figure 1 The horizontal support steel pipes 400 are equipped with fasteners 430, and the prefabricated shear wall 500 and the floor slab are respectively equipped with shear wall embedded parts 510 and floor slab embedded parts 520, so that the horizontal support steel pipes 400 are horizontally distributed. The fasteners 430 at the first end 410 are connected to the shear wall embedded parts 510 in the lower area of ​​the prefabricated shear wall 500, and the fasteners 430 at the second end 420 are connected to the floor slab embedded parts 520 on the floor slab, so that the horizontal support steel pipes 400 and the prefabricated shear wall 500 are stably connected and can firmly support the prefabricated shear wall 500.

[0052] Furthermore, the inclined adjustable support steel pipe 300 is provided with adjustable connectors 310 at both ends, so that one end of the inclined adjustable support steel pipe 300 is connected to the shear wall embedded part 510 in the upper area of ​​the prefabricated shear wall 500 through the adjustable connector 310, and the other end is connected to the floor slab embedded part 520 corresponding to the second end 420 of the horizontal support steel pipe 400 through the adjustable connector 310. This makes the inclined adjustable support steel pipe 300 and the horizontal support steel pipe 400 distributed at an angle, and distributed in a triangle with the prefabricated shear wall 500, which can stably support the prefabricated shear wall 500.

[0053] Combination Figure 2 The adjusting connector 310 is preferably made of a threaded rod and is configured to be threadedly connected to the inclined adjusting support steel pipe 300, so that the inclined adjusting support steel pipe 300 can be rotated to adjust the connection length between the adjusting connector 310 and the inclined adjusting support steel pipe 300, thereby extending or shortening the inclined adjusting support steel pipe 300.

[0054] Since the ends of the horizontal support steel pipe 400 and the inclined adjustment support steel pipe 300 are fixed, the included angle between the horizontal support steel pipe 400 and the inclined adjustment support steel pipe 300 remains constant. At the same time, the horizontal support steel pipe 400 is horizontally distributed. Therefore, the extension or shortening of the inclined adjustment support steel pipe 300 can cause the prefabricated shear wall 500 to tilt, thereby adjusting the included angle between the horizontal support steel pipe 400 and the prefabricated shear wall 500. When the included angle between the horizontal support steel pipe 400 and the prefabricated shear wall 500 is closer to a right angle, the verticality error of the prefabricated shear wall 500 is smaller, thereby correcting the verticality of the prefabricated shear wall 500.

[0055] Combination Figure 3 In order to precisely adjust the length of the inclined adjustment support steel pipe 300 and effectively control the verticality error of the prefabricated shear wall 500, the ranging device 100 includes a laser rangefinder 110 and a leveling bracket 120. The laser rangefinder 110 and the leveling bracket 120 can work together to accurately obtain the distribution angle between the horizontal support steel pipe 400 and the inclined adjustment support steel pipe 300.

[0056] Combination Figure 1 and Figure 3 Specifically, the laser rangefinder 110 is spaced apart from the prefabricated shear wall 500 and is set at the connection between the second end 420 of the horizontal support steel pipe 400 and the floor slab embedded part 520. It emits a horizontal laser 112 and an oblique laser 111 to the prefabricated shear wall 500, and ensures that the horizontal laser 112 and the oblique laser 111 are parallel to the horizontal support steel pipe 400 and the oblique adjusting support steel pipe 300, respectively, so as to accurately obtain the distribution angle of the horizontal support steel pipe 400 and the oblique adjusting support steel pipe 300.

[0057] Here, the laser rangefinder 110 is preferably placed next to the inclined adjustment support steel pipe 300 to facilitate observation of the parallelism between the inclined laser 111 and the inclined adjustment support steel pipe 300.

[0058] Furthermore, the laser rangefinder 110 is provided with a leveling bracket 120 at the bottom. The leveling bracket 120 is configured to adjust the placement angle of the laser rangefinder 110 to level the laser rangefinder 110, so as to ensure that the horizontal laser 112 is horizontal and the oblique laser 111 is parallel to the oblique adjustment support steel pipe 300, thereby improving the measurement accuracy.

[0059] The laser rangefinder 110 thus constitutes a laser rangefinder 110 that can measure the horizontal distance x and the oblique distance y between the center of the laser rangefinder 110 and the prefabricated shear wall 500, as well as the angle α between the horizontal distance x and the oblique distance y, by emitting a horizontal laser 112 and an oblique laser 111. The horizontal distance x and the oblique distance y are parallel to the horizontal support steel pipe 400 and the oblique adjusting support steel pipe 300, respectively. Therefore, the distribution angle between the horizontal support steel pipe 400 and the oblique adjusting support steel pipe 300 is the angle α.

[0060] Since the laser rangefinder 110 is set at the connection between the second end 420 of the horizontal support steel pipe 400 and the floor slab embedded part 520, the horizontal distance x between the center of the laser rangefinder 110 and the prefabricated shear wall 500 is consistent with the horizontal distance from the floor slab embedded part 520 to the prefabricated shear wall 500.

[0061] Furthermore, the laser rangefinder 110 is equipped with a signal transmitter, which can transmit the real-time acquired horizontal distance x, oblique distance y, and included angle α to the vertical adjustment device 200, providing the vertical adjustment device 200 with accurate measurement data.

[0062] Combination Figure 4 In conjunction with this, a sag adjustment device 200 is installed at the second end 420 region of the horizontal support steel pipe 400, including a housing 270, a support rod 290 and a reaction bracket 280 installed at the bottom of the housing 270, and a steel pipe clamping device 240 installed at the top of the housing 270. This allows the housing 270, support rod 290, reaction bracket 280 and steel pipe clamping device 240 to cooperate in stably mounting the sag adjustment device 200, and enables the sag adjustment device 200 to stably adjust the length of the inclined support steel pipe 300.

[0063] Specifically, the housing 270 is positioned between the second end 420 region of the horizontal support steel pipe 400 and the inclined adjustment support steel pipe 300, so that the support rod 290 and the reaction bracket 280 can cooperate with the horizontal support steel pipe 400 to stably support the housing 270, and the steel pipe clamping device 240 can cooperate with the inclined adjustment support steel pipe 300 to adjust the length of the inclined adjustment support steel pipe 300.

[0064] The top of the housing 270 has a first inclined surface 271 that is adapted to the inclined adjustment support steel pipe 300, so that the inclined adjustment support steel pipe 300 is connected by the steel pipe clamping device 240 and distributed above the first inclined surface 271, and the inclined adjustment support steel pipe 300 will not collide with the housing 270 when it extends or retracts.

[0065] Furthermore, a second inclined surface 272 is formed at the bottom of the housing 270 corresponding to one end of the steel pipe clamping device 240, so that the reaction support 280 is set on the second inclined surface 272 to provide a reaction force for the steel pipe clamping device 240, ensuring that the steel pipe clamping device 240 and the inclined adjustment support steel pipe 300 are stably matched.

[0066] Combination Figure 4 and Figure 5 Specifically, the reaction support 280 includes a reaction plate 281 and reaction rods 282. The reaction plate 281 is set on the second inclined surface 272, and reaction rods 282 are distributed on the four corners of the reaction plate 281. One end of the reaction rod 282 supports the reaction plate 281, and the other end is distributed on both sides of the horizontal support steel pipe 400. They cooperate to clamp and abut against the horizontal support steel pipe 400, so that the reaction rod 282 generates pressure on the horizontal support steel pipe 400. The pressure will generate a reverse support force on the reaction rod 282, so that the reaction rod 282, through the reaction plate 281 and the housing 270, holds the reverse support steel pipe clamping device 240, ensuring that the steel pipe clamping device 240 can stably cooperate with the inclined adjustment support steel pipe 300 to adjust the length of the inclined adjustment support steel pipe 300.

[0067] Combination Figure 4 Furthermore, the support rod 290 is located at the end of the housing 270 away from the steel pipe clamping device 240 and is distributed on both sides of the horizontal support steel pipe 400, with a distance between them, so that the support rod 290 can cooperate with the reaction support 28 to stably support the housing 270.

[0068] Meanwhile, when the sag adjustment device 200 is removed from the inclined adjustment support steel pipe 300 and the horizontal support steel pipe 400, the support rod 290 can cooperate with the reaction bracket 28 to keep the housing 270 horizontally placed, thereby improving its service life.

[0069] In order for the steel pipe clamping device 240 to adjust the length of the inclined adjustment support steel pipe 300 according to the measurement data of the laser rangefinder 110, the housing 270 is equipped with an industrial control computer 210, a power system 220 and an output gear 230, so that the industrial control computer 210, the power system 220 and the output gear 230 can work together to drive the steel pipe clamping device 240 to adjust the length of the inclined adjustment support steel pipe 300.

[0070] Combination Figure 6 Specifically, the industrial computer 210 is connected to the power system 220, and the output shaft of the power system 220 is connected to the output gear 230, so that the industrial computer 210 drives the power system 220 to rotate, which in turn drives the output gear 230 to rotate synchronously.

[0071] Here, the power system 220 is preferably composed of a servo motor, and the rotation angle accuracy of the servo motor is 1 / 360 degrees, so as to improve the rotation accuracy of the output gear 230.

[0072] Combination Figure 2 and Figure 6 In conjunction with this, the steel pipe clamping device 240 includes a steel pipe connector 242 and a transmission gear 241. The steel pipe connector 242 and the transmission gear 241 are connected as a whole, and the steel pipe connector 242 clamps the inclined adjustment support 300. The transmission gear 241 meshes with the output gear 230, so that the rotation of the output gear 230 can drive the transmission gear 241 to rotate synchronously. Thus, the steel pipe connector 242 drives the inclined adjustment support steel pipe 300 to rotate synchronously, so as to adjust the threaded connection length between the inclined adjustment support steel pipe 300 and the adjustable connector 310, thereby adjusting the extension and retraction of the inclined adjustment support steel pipe 300.

[0073] Furthermore, the inner side of the steel pipe connector 242 is provided with a groove, which abuts against the inclined adjustment support steel pipe 300, enhancing the frictional force transmission between the steel pipe connector 242 and the inclined adjustment support steel pipe 300, ensuring that the steel pipe clamping device 240 can stably cooperate with the inclined adjustment support steel pipe 300 to adjust the length of the inclined adjustment support steel pipe 300.

[0074] To precisely and in real-time adjust the length of the inclined adjustment support steel pipe 300, the industrial control computer 210 consists of a signal receiver, a processor, and an internal memory. The signal receiver can receive the horizontal distance x, the inclined distance y, and the included angle α sent by the ranging device 100 in real time. The processor is equipped with a calculation program that can automatically process the measurement data in real time, input the three parameters of horizontal distance x, inclined distance y, and included angle α, and generate the verticality deviation of the prefabricated shear wall 500, providing adjustment parameters for the steel pipe clamping device 240.

[0075] Specifically, in combination Figure 1 and Figure 3 The horizontal distance x from the center of the laser rangefinder 110 to the prefabricated shear wall 500 is consistent with the horizontal distance from the floor slab embedded part 520 to the prefabricated shear wall 500. The verticality deviation includes the measured deviation distance Δy. Combining the horizontal distance x and the included angle α, the horizontal distance x and the vertical oblique distance y when the prefabricated shear wall 500 is vertical can be obtained. x The height z of the prefabricated shear wall (500mm) forms a right triangle. According to trigonometric functions, the vertical oblique distance y... x for

[0076] y x = x / cos α.

[0077] Furthermore, adjust the diagonal distance y to be the same as the vertical diagonal distance y xWhen they are aligned, the horizontal distance x, the diagonal distance y, and the height z of the prefabricated shear wall 500 will form a right triangle, making the prefabricated shear wall 500 vertical.

[0078] Therefore, the measurement deviation distance Δy is...

[0079] Δy=|y x -y|,

[0080] Verticality deviation also includes the vertical deviation angle δ of the prefabricated shear wall 500. Combining the measured deviation distance Δy, the height z of the prefabricated shear wall 500, and the included angle α, and then applying the sine theorem, we can obtain...

[0081]

[0082] Therefore, the vertical deviation angle δ and the sine value sinδ of the vertical deviation angle δ are obtained for the prefabricated shear wall 500.

[0083]

[0084]

[0085] Combined Figure 7 The verticality deviation also includes the oblique deviation distance Δl that the oblique adjustment support steel pipe 300 needs to be lengthened or shortened, the horizontal distance x, the length l of the oblique adjustment support steel pipe 300, and the vertical height h between the shear wall embedded part 510 and the floor slab embedded part 520 connected to both ends of the oblique adjustment support steel pipe 300 forming a right triangle. According to the inverse trigonometric function, the angle β between the oblique adjustment support steel pipe 300 and the horizontal direction is...

[0086]

[0087] According to the law of sines

[0088]

[0089] Therefore, the oblique deviation distance Δl that the oblique adjustment support steel pipe 300 needs to be lengthened or shortened is:

[0090]

[0091] Therefore, by adjusting the length of the inclined adjustment support steel pipe 300 or shortening the inclined deviation distance Δl, the inclined adjustment support steel pipe 300, the horizontal distance x, and the prefabricated shear wall 500 can be arranged into a right-angled triangle to make the prefabricated shear wall 500 vertical, thereby correcting the verticality of the prefabricated shear wall 500.

[0092] Furthermore, in order for the industrial control computer 210 to precisely control the rotation angle of the power system 220, thereby controlling the rotation angle of the output gear 230, so that the rotation of the output gear 230 can precisely extend or shorten the oblique deviation distance Δl of the oblique adjustment support steel pipe 300, and the verticality deviation also includes the verticality adjustment angle θ.

[0093] Wherein, the vertical adjustment angle θ is

[0094] θ=360Δl / s

[0095] In the formula, s is the pitch of the adjustable connectors 310 at both ends of the inclined adjustable support steel pipe 300, that is, the distance between the start and end points of a single thread turn along the length of the screw. Figure 2 As shown.

[0096] The industrial control computer 210, power system 220 and output gear 230 thus constitute can cooperate with the steel pipe clamping device 240 to adjust the length of the inclined adjustment support steel pipe 300 in real time and accurately, thereby precisely controlling the verticality error of the prefabricated shear wall 500.

[0097] Specifically, if the vertical oblique distance y x If the oblique distance y is greater than the vertical distance y, the industrial control computer 210 controls the output gear 230 to rotate counterclockwise to adjust the vertical angle θ, thereby adjusting the oblique deviation distance Δl of the oblique adjustment support steel pipe 300. If the vertical oblique distance y is greater than the vertical distance y, the industrial control computer 210 controls the output gear 230 to rotate counterclockwise to adjust the vertical angle θ, thereby adjusting the oblique deviation distance Δl of the ob x If the oblique distance y is less than the oblique distance, the industrial control computer 210 controls the output gear 230 to rotate clockwise to adjust the vertical angle θ, so as to adjust the oblique adjustment support steel pipe to shorten the oblique deviation distance Δl.

[0098] Furthermore, the sag adjustment device 200 is also equipped with a drive power supply 250. The drive power supply 250 is fixed to the inner side of the housing 270 by a U-shaped clip to provide power to the industrial control computer 210 and the power system 220. Preferably, the drive power supply 250 is composed of a rechargeable lithium battery to ensure that the drive power supply 250 can provide sufficient power to the industrial control computer 210 and the power system 220.

[0099] Furthermore, the housing 270 is equipped with a display screen 260, which is configured to display the measurement data of the ranging device 100 and the verticality deviation obtained by the vertical adjustment device 200 in real time.

[0100] This constitutes the prefabricated shear wall verticality correction device of the present invention.

[0101] This invention also provides a construction method for correcting the verticality of prefabricated shear walls. Based on the prefabricated shear wall verticality correction equipment provided in the above solution, this construction method includes:

[0102] Connect the horizontal support steel pipe 400 and the inclined adjustment support steel pipe 300 to the prefabricated shear wall 500, the leveling and measuring device 100, and the plumb device 200.

[0103] First, connect the fasteners 430 at both ends of the horizontal support steel pipe 400 to the prefabricated shear wall 500 and the embedded parts of the floor slab respectively, and tighten the fasteners to the embedded parts firmly; then connect the adjustable connectors 310 at both ends of the inclined adjustment support steel pipe 300 to the prefabricated parts of the shear wall 510 and the prefabricated parts of the floor slab 520 respectively.

[0104] At the same time, the laser rangefinder 110 of the ranging device 100 and the leveling bracket 120 are installed and connected as a whole. The leveling bracket 120 is unfolded and placed next to the inclined adjustment support steel pipe 300, and the laser rangefinder 110 is leveled.

[0105] Next, tighten the steel pipe clamping device 240 of the sag adjustment device 200 to the inclined adjustment support steel pipe 300. The reaction bracket 280 of the sag adjustment device clamps the horizontal support steel pipe 400, and the reaction rod 282 provides support reaction force by contacting the horizontal support steel pipe 400, ensuring that the steel pipe clamping device 240 can drive the inclined adjustment support steel pipe 300 to rotate, thereby adjusting the length of the inclined adjustment support steel pipe 300.

[0106] Next, the distance measuring device 100 measures in real time the horizontal distance x and the oblique distance y between the center of the distance measuring device 100 and the prefabricated shear wall 500, as well as the angle α between the horizontal distance x and the oblique distance y, and ensures that the horizontal distance x and the oblique distance y are parallel to the horizontal support steel pipe 400 and the oblique adjusting support steel pipe 300, respectively, and transmits the measurement data to the vertical adjustment device 200 in real time.

[0107] Next, the vertical adjustment device 200 receives the measurement data in real time and processes the data to obtain the vertical oblique distance y. x To obtain the verticality deviation of the prefabricated shear wall 500, the verticality deviation includes the measured deviation distance Δy, the vertical deviation angle δ of the prefabricated shear wall 500, the oblique deviation distance Δl of the inclined adjustment support steel pipe 300, and the adjustment angle θ, wherein...

[0108] The measurement deviation distance Δy is

[0109] y x =x / cosα,

[0110] Δy=|y x -y|,

[0111] Therefore, the vertical deviation angle δ of the prefabricated shear wall 500 can be obtained as follows:

[0112]

[0113] The oblique deviation distance Δl of the oblique adjustment support steel pipe 300 is

[0114]

[0115] The vertical angle θ is

[0116] θ=360Δl / s

[0117] In the formula, Z represents the height of the prefabricated shear wall 500, ...

[0118] In the sag adjustment device 200, the industrial control computer 210 controls the output gear to rotate and adjust the sag angle θ, so as to adjust the lengthening or shortening of the oblique adjustment support steel pipe by the oblique deviation distance Δl.

[0119] If the vertical oblique distance y x If the oblique distance y is greater than the vertical distance y, the industrial control computer 210 controls the output gear 230 to rotate counterclockwise to adjust the vertical angle θ, thereby adjusting the oblique deviation distance Δl of the oblique adjustment support steel pipe 300. If the vertical oblique distance y is greater than the vertical distance y, the industrial control computer 210 controls the output gear 230 to rotate counterclockwise to adjust the vertical angle θ, thereby adjusting the oblique deviation distance Δl of the ob x When the oblique distance y is less than the oblique distance, the industrial control computer 210 controls the output gear 230 to rotate clockwise to adjust the vertical angle θ, which easily adjusts the oblique adjustment support steel pipe to shorten the oblique deviation distance Δl.

[0120] Repeat the above adjustment process until the verticality of the prefabricated shear wall meets the allowable deviation requirements of the specification.

[0121] This completes the verticality correction of the 500mm prefabricated shear wall.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
