Description

Technical Field

[0001] The present invention relates to the technical field of house construction, and in particular to a unit module lifting device and method for integrated metal roof construction. Background Art

[0002] Metal roofing is currently widely used in the field of large-span steel structures. Traditional large-span metal roof construction methods are very cumbersome, requiring the metal roof to be hoisted layer by layer in a sequential manner. This traditional sequential construction method has many disadvantages, including long waiting times at each stage of construction. Furthermore, the heavy overhead work involved in metal roofing leads to low construction efficiency and delayed watertightness, making it unsuitable for today's building technology requirements.

[0003] In response to the above construction problems, the existing technology has proposed an integrated construction method for metal roofs. The integrated construction of metal roofs forms unit modules, which are hoisted using through-hole jacks and cranes. Although the integrated construction has shortened the construction period and improved construction efficiency to a certain extent, the weight and span of the integrated unit modules of the metal roofs are very large. Using existing hoisting equipment to hoist them will result in a very slow hoisting process. The construction conditions are harsh and difficult, which can easily cause deformation of the metal roof and affect its performance. Therefore, how to reduce the deformation of the metal roof during the overall hoisting of the unit modules, how to ensure the reliability of the connection between the hoisting equipment and the metal roof, and the tediousness of hoisting and disassembling the metal roof are still technical problems that cannot be solved at present. Therefore, they need to be solved urgently. Summary of the Invention

[0004] In order to solve the above problems, the present invention aims to propose a unit module lifting device and method for integrated metal roof construction. The tooling body is perceptible, adjustable, disassembled and reusable, and can greatly control the deformation of the metal roof during the lifting process, thereby realizing the unit module lifting requirements of integrated large-span metal roof construction.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] A unit module lifting device for integrated metal roof construction includes an I-shaped tooling body, and adjustable clamping plates are connected to the upper ends of the I-shaped tooling body on both sides through rotating shafts. An interlocking gasket is detachably installed on the outer side of the adjustable clamping plate, and a bite tooth is installed at the end of the interlocking gasket. A force sensor is installed in the bite tooth, and a driver is installed in the adjustable clamping plate for driving the rotating shaft to rotate. The lower ends of the I-shaped tooling body are used to place metal roofing units on both sides.

[0007] Furthermore, the I-shaped tooling body includes a T-shaped convex tooth connecting plate and a T-shaped concave tooth connecting plate. The connecting ends of the T-shaped convex tooth connecting plate and the T-shaped concave tooth connecting plate are respectively provided with mutually matching convex teeth and concave teeth. The T-shaped convex tooth connecting plate and the T-shaped concave tooth connecting plate are magnetically connected and matched with the corresponding convex teeth and concave teeth to achieve fixed splicing to form the I-shaped tooling body.

[0008] Furthermore, the number of convex teeth is less than the number of concave teeth; the rotating shaft includes a motor connecting rod and a drive motor, and the drive motor is provided in two groups, and the two groups of drive motors are respectively installed on both ends of one side of the T-shaped convex tooth connecting plate to drive the motor connecting rod to rotate to the set position; the motor connecting rod and the adjustable clamping plate are integrally formed.

[0009] Furthermore, the metal roofing units placed on both sides of the lower end of the I-shaped tooling body are respectively in contact with the connecting ends of the T-shaped convex tooth connecting plate and the T-shaped concave tooth connecting plate.

[0010] Furthermore, the T-shaped convex tooth connecting plate and the T-shaped concave tooth connecting plate are respectively located at the upper and lower ends of the I-shaped tooling body, and gripping gaskets are detachably installed on both sides of the bottom plate of the T-shaped concave tooth connecting plate, and a grip is provided at the end of the gripping gasket.

[0011] Furthermore, a hook is provided on the upper end of the T-shaped convex tooth connecting plate.

[0012] Furthermore, at least two groups of mounting holes are respectively provided in the length direction of the gripping gasket and the bite-type gasket. The gripping gasket and the bite-type gasket are respectively detachably fixedly connected to the T-shaped concave tooth connecting plate and the adjustable clamping plate through their respective mounting holes with bolts and nuts.

[0013] Furthermore, a force sensor is installed in the grip, and the bite teeth and grip are assisted in guiding the connection of the bite teeth and grip with the purlins on the upper part of the metal roof unit and the I-beam on the lower part in real time through the force values ​​monitored by the force sensor.

[0014] Furthermore, the connecting ends of the T-shaped convex tooth connecting plate and the T-shaped concave tooth connecting plate are both strong electromagnets.

[0015] In order to achieve the above object, the present invention also provides a method for lifting a unit module for integrated metal roof construction, comprising the following steps:

[0016] Step 1: Place the two integrated metal roof units to be connected between a T-shaped convex tooth connection plate and a T-shaped concave tooth connection plate with an adjustable clamping plate. The two connection plates can adjust the size of the connection space according to the height of the metal roof, and the height is adjusted according to the number of teeth of the two connection plates. After the height adjustment is completed, the two connection plates are made of strong magnets and use magnetic force to connect the two.

[0017] Step 2: A driver and a force sensor are installed in the adjustable pressing plate. The driver drives the rotating shaft to rotate, driving the adjustable pressing plate and the bite-type gasket and the grip-type gasket to move, adjusting the angle to facilitate construction and ensure that the adjustable pressing plate, the T-shaped convex tooth connecting plate, the T-shaped concave tooth connecting plate and the surface of the metal roof unit are in close contact;

[0018] Step 3: Bolt washers adopt two types of gaskets: bite-type gaskets and grip-type gaskets. The bite-type gasket adopts a bite-type structure. While playing the role of gasket, the bite teeth are embedded in the metal roof unit; the grip-type gasket adopts a palm-type structure and adopts an articulated connector to imitate the palm, and use the palm to tightly grip the flange of the I-beam to ensure load-bearing capacity; there are force sensors in the bite teeth and the grip to sense the change of force during the bite process, and receive and transmit signals to the computer through the signal station for real-time imaging analysis; when the bite teeth are connected to the upper main purlin of the metal roof unit, and the grip is connected to the lower I-beam of the metal roof unit, the computer-side data analysis is used to ensure that they are tightly connected to ensure their load-bearing capacity;

[0019] Step 4: After the connection is completed, use bolts to provide compensation force. The bolts are embedded in the metal roof unit. The upper bolts pass through the bite-type gasket, the adjustable pressure plate and the metal roof unit, and are connected to the upper main purlin of the metal roof unit. The lower bolts pass through the grip-type gasket, the T-shaped concave tooth connection plate and the metal roof unit, and are connected to the lower I-beam of the metal roof unit, thereby strengthening the fastening of the lifting fixture and the metal roof unit.

[0020] Step 5: After the metal roof unit and the lifting fixture are connected, the hook is used to assist in the lifting. At the same time, the force sensor constantly senses the changes of the metal roof unit and the lifting fixture during the lifting process. The signal is received and transmitted to the computer through the signal station to monitor the lifting construction process in real time, control the lifting speed and method, ensure smooth lifting, reduce deformation of the metal roof, and provide construction guidance;

[0021] Step 6: Because holes are generated in the connection between the bolts, teeth and metal roof units, the bolts and teeth are only connected to the upper load-bearing structure of the metal roof unit, and the waterproof layer is not damaged, but the decorative layer is damaged to a certain extent; after the lifting is completed, the lifting tooling is dismantled, and the holes are filled and specialized waterproofing and decorative treatments are performed.

[0022] Beneficial effects: The tooling body of the present invention is perceptible, adjustable, detachable and reusable, and can control the deformation of the metal roof during the hoisting process to the greatest extent, thus realizing the unit module hoisting requirements of the integrated construction of the large-span metal roof.

[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0034] Example 1

[0035] See also Figure 1-8 : A unit module lifting device for integrated metal roof construction, including an I-shaped tooling body 1, and adjustable clamping plates 3 are connected to the upper ends of the I-shaped tooling body 1 on both sides through a rotating shaft 2, and a bite-type gasket 4 is detachably installed on the outer side of the adjustable clamping plate 3, and a bite tooth 5 is installed at the end of the bite tooth 5, and a force sensor is installed in the bite tooth 5, and a driver is installed in the adjustable clamping plate 3 for driving the rotating shaft 2 to rotate, and the lower ends of the I-shaped tooling body 1 are used to place metal roofing units 6 on both sides.

[0036] A metal roof unit can be placed on each side of the lower end of the I-shaped tooling body of this embodiment. The rotation of the rotating shaft is controlled by the driver, thereby realizing the rotation of the adjustable clamping plate and cooperating with the interlocking gasket and the biting teeth to press and fix the metal roofing units on both sides. Two metal roofing units can be lifted at one time with good balance and high efficiency. At the same time, the safety and stability of the metal roofing units during the lifting process can be guaranteed. In addition, the biting teeth of this embodiment have built-in force sensors, which can sense changes in force through the force sensors, provide assistance for lifting construction, adjust the lifting speed and method, reduce the deformation of the metal roof, and ensure its safety and usability. The interlocking gaskets and biting teeth of this embodiment can be disassembled and replaced, so that they can be suitable for grasping metal roofing units of different shapes and sizes, thereby improving adaptability.

[0037] In a specific example, the I-shaped tooling body 1 includes a T-shaped convex tooth connecting plate 101 and a T-shaped concave tooth connecting plate 102. The connecting ends of the T-shaped convex tooth connecting plate 101 and the T-shaped concave tooth connecting plate 102 are respectively provided with mutually matching convex teeth and concave teeth. The T-shaped convex tooth connecting plate 101 and the T-shaped concave tooth connecting plate 102 are magnetically connected and matched with the corresponding convex teeth and concave teeth to achieve fixed splicing to form the I-shaped tooling body 1.

[0038] The I-shaped tooling body of this embodiment is detachably spliced ​​by the corresponding convex teeth and concave teeth between the T-shaped convex tooth connecting plate and the T-shaped concave tooth connecting plate. Since the T-shaped convex tooth connecting plate and the T-shaped concave tooth connecting plate have strong magnetism, the splicing structure of the two is firm.

[0039] In a specific example, the number of convex teeth is less than the number of concave teeth; the rotating shaft 2 includes a motor connecting rod 201 and a drive motor 202, and the drive motor 202 is provided in two groups. The two groups of drive motors 202 are respectively installed on both ends of one side of the T-shaped convex tooth connecting plate 101 to drive the motor connecting rod 201 to rotate to the set position; the motor connecting rod 201 is integrally formed with the adjustable clamping plate 3.

[0040] The number of convex teeth of the T-shaped convex tooth connecting plate of this embodiment is less than the number of concave teeth of the T-shaped concave tooth connecting plate. Therefore, the upper and lower heights between the connecting plates of the T-shaped convex tooth connecting plate and the T-shaped concave tooth connecting plate of this embodiment are adjustable. Therefore, the inner side accommodation height of the I-shaped tooling body can be adjusted, thereby being suitable for the placement of metal roofing units of different thicknesses, and having strong adaptability.

[0041] In this embodiment, the driver can drive the driving motors installed at both ends of one side of the T-shaped protruding tooth connecting plate to drive the motor connecting rod to adjust the position, thereby driving the biting teeth to connect to the purlins on the upper part of the metal roof unit.

[0042] In a specific example, the metal roofing units 6 placed on both sides of the lower end of the I-shaped tooling body 1 respectively abut against the connecting ends of the T-shaped convex tooth connecting plate 101 and the T-shaped concave tooth connecting plate 102.

[0043] The strong magnetic attraction connection between the T-shaped convex tooth connecting plate and the T-shaped concave tooth connecting plate in this embodiment cooperates with the two metal roofing units placed on both sides of the lower end of the I-shaped tooling body to form abutment with the connecting ends of the T-shaped convex tooth connecting plate and the T-shaped concave tooth connecting plate, thereby further preventing the risk of left and right displacement caused by disengagement between the convex teeth and the concave teeth at the connecting ends of the T-shaped convex tooth connecting plate and the T-shaped concave tooth connecting plate, and the lifting safety can be further guaranteed.

[0044] In a specific example, the T-shaped convex tooth connecting plate 101 and the T-shaped concave tooth connecting plate 102 are respectively located at the upper and lower ends of the I-shaped tooling body 1, and the two sides of the bottom plate of the T-shaped concave tooth connecting plate 102 are detachably installed with gripping gaskets 7, and the ends of the gripping gaskets 7 are provided with grips 8.

[0045] When metal roof units are placed at both ends of the bottom plate of the T-shaped concave tooth connecting plate of this embodiment, the metal roof can be tightly grasped by the gripping gasket and the gripping palm, thereby improving the safety of lifting.

[0046] In a specific example, a hook 9 is provided on the upper end of the T-shaped protruding tooth connecting plate 101 .

[0047] During the lifting process, the hook on the upper end of the T-shaped convex tooth connecting plate can assist in lifting and improve the safety of lifting.

[0048] In a specific example, at least two groups of mounting holes are respectively provided in the length direction of the gripping gasket 7 and the bite-type gasket 4. The gripping gasket 7 and the bite-type gasket 4 are respectively detachably fixedly connected to the T-shaped concave tooth connecting plate 102 and the adjustable clamping plate 3 through their respective mounting holes with bolts and nuts.

[0049] The gripping gaskets and biting gaskets of this embodiment are both detachably fixed to the T-shaped concave tooth connecting plate and the adjustable pressure plate by means of bolts and nuts. In addition, since the gripping gaskets and biting gaskets are provided with at least two groups of mounting holes in the length direction, the gripping gaskets and biting gaskets of this embodiment can extend outward in the length direction, thereby increasing the gripping and biting range of the palm and the biting teeth, being suitable for metal roofing units of different widths, and improving applicability.

[0050] In a specific example, a force sensor is installed in the grip 8, and the bite teeth 5 and grip 8 use the force values ​​monitored by the force sensor to assist in guiding the bite teeth 5 and grip 8 to connect with the upper purlins and the lower I-beam of the metal roof unit 6 in real time.

[0051] It should be noted that after the connection with the metal roof unit is completed, the bolt connection is used to provide compensation force to ensure the stability of the hoisting; the upper bolts connect the bite-type gasket, adjustable plate and metal roof unit, and the bolts are connected to the upper main purlin of the metal roof unit without damaging the waterproof layer of the metal roof; the lower bolts connect the grip-type gasket, adjustable plate and metal roof unit, and the bolts are connected to the I-beam at the bottom of the metal roof;

[0052] During the hoisting process, the hook on the upper part of the device is used to assist the hoisting. During the hoisting process, the intelligent force sensors in the teeth, grip and adjustable plate also sense the changes in force in real time, and receive and transmit signals to the computer through the signal station, and conduct real-time imaging analysis to adjust the hoisting speed and method to ensure the smoothness of the hoisting, reduce the changes in the force of the metal roof unit, reduce the deformation of the metal roof unit during the hoisting process, and improve the safety of the hoisting.

[0053] In a specific example, the connecting ends of the T-shaped convex tooth connecting plate 101 and the T-shaped concave tooth connecting plate 102 are both strong electromagnets.

[0054] From the above calculations, it can be seen that the magnetic attraction force of the strong magnet connection ends of the U-shaped convex tooth connection plate and the T-shaped concave tooth connection plate of this embodiment meets the design requirements for safe connection.

[0055] Example 2

[0056] This embodiment also provides a method for lifting a unit module for integrated metal roof construction, comprising the following steps:

[0057] Step 1: Place the two integrated metal roof units 6 to be connected between a T-shaped convex tooth connection plate 101 and a T-shaped concave tooth connection plate 102 with an adjustable pressing plate 3. The two connection plates can adjust the size of the connection space according to the height of the metal roof, and the height can be adjusted according to the number of teeth of the two connection plates. After the height adjustment is completed, the two connection plates are made of strong magnet material and use magnetic force to connect the two.

[0058] Step 2: A driver and a force sensor are provided in the adjustable pressing plate 3. The driver drives the rotating shaft 2 to rotate, thereby driving the adjustable pressing plate 3, the bite-type gasket 4, and the grip-type gasket 7 to move, thereby adjusting the angle to facilitate construction and ensure that the adjustable pressing plate 3, the T-shaped convex tooth connecting plate 101, and the T-shaped concave tooth connecting plate 102 are in close contact with the surface of the metal roofing unit 6;

[0059] Step 3: The bolt washers adopt two types of gaskets: bite-type gaskets 4 and grip-type gaskets 7. The bite-type gasket 4 adopts a bite-type structure. While playing the role of a gasket, the bite teeth 5 are embedded in the metal roof unit 6; the grip-type gasket 7 adopts a hand-palm structure and adopts an articulated connector to imitate the palm, and uses the grip 8 to tightly grip the flange of the I-beam to ensure load-bearing capacity; there are force sensors in the bite teeth 5 and the grip 8 to sense the changes in force during the bite process, and receive and transmit signals to the computer through the signal station for real-time imaging analysis; when the bite teeth 5 are connected to the upper main purlin of the metal roof unit 6, and the grip 8 is connected to the lower I-beam of the metal roof unit 6, the computer-side data analysis is used to ensure that they are tightly connected to ensure their load-bearing capacity;

[0060] Step 4: After the connection is completed, use bolts to provide compensation force. The bolts are embedded in the metal roof unit 6. The upper bolts pass through the bite-type gasket 4, the adjustable pressure plate 3 and the metal roof unit 6, and are connected to the upper main purlin of the metal roof unit 6. The lower bolts pass through the grip-type gasket 7, the T-shaped concave tooth connection plate 102 and the metal roof unit 6, and are connected to the lower I-beam of the metal roof unit 6, thereby strengthening the fastening of the lifting fixture and the metal roof unit 6.

[0061] Step 5: After the metal roof unit 6 and the lifting fixture are connected, the lifting hook 9 is used to assist in the lifting. At the same time, the force sensor is used to constantly sense the changes of the metal roof unit 6 and the lifting fixture during the lifting process. The signal is received and transmitted to the computer through the signal station to monitor the lifting construction process in real time, control the lifting speed and method, ensure smooth lifting, reduce deformation of the metal roof, and provide construction guidance;

[0062] Step 6: Since holes are generated in the connection between the bolts, the teeth 5 and the metal roof unit, the bolts and the teeth 5 are only connected to the upper load-bearing structure of the metal roof unit 6, and the waterproof layer is not damaged, but the decorative layer is damaged to a certain extent; after the lifting is completed, the lifting tooling is dismantled, the holes are filled, and special waterproofing and decorative treatments are performed.

[0063] The method for lifting the unit module for integrated metal roof construction of this embodiment has the same advantages as the above-mentioned unit module lifting device for integrated metal roof construction over the prior art, and will not be repeated here.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
