[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Please see Figure 1 and Figure 2 An efficient and safe method for installing corrugated sandwich roofing panels, specifically including the following steps:

[0031] S1: Remove the lifting clamp 4 from one side of the lifting tool 1, then place the corrugated plate on the lifting clamp 4 on the other side of the lifting tool 1, and then put the removed lifting clamp 4 back on.

[0032] S2: Rotate the screw 2 to drive the pressure plate 3 to press the corrugated sheet downwards, which is used to prevent the corrugated sheet from slipping off the lifting clamp 4. Install the adjusting clamp on one side of the corrugated sheet and use slings to connect the adjusting clamp to the lifting tool 1. After careful inspection to ensure safety, the lifting will begin.

[0033] S3: Lift the hoisting tool 1, hoist the corrugated sheet onto the roof, bring its protruding side close to the installed corrugated sheet, rotate the screw rod 2 so that the pressure plate 3 does not contact the corrugated sheet, and loosen the corrugated sheet; remove the hoisting clamp 4 on one side of the hoisting tool 1, and install the removed hoisting clamp 4 onto the bolt holes of the hoisting tool 1 (the area where the hoisting clamp 4 is temporarily fixed, the hoisting clamp 4 is fixed to the hoisting tool 1 by bolts); then slowly push the hoisting tool 1 away from the corrugated sheet to separate the hoisting tool 1 from the corrugated sheet.

[0034] S4: Use a crane to slowly lift the lifting tool 1. Stop lifting the lifting tool 1 when the sling connecting the lifting tool 1 and the adjusting tool is about to be taut. Then the worker will engage the inner side of the corrugated board with the previous corrugated board.

[0035] S5: After the two corrugated sheets are interlocked, the outer side of the corrugated sheets is slowly lifted upwards using a pre-fixed adjustment clamp, thereby adjusting and positioning the two corrugated sheets at the joint and fixing them with rivets.

[0036] S6: After the corrugated sheet is installed and adjusted, remove the adjustment clamps, then remove the adjustment tools from the corrugated sheet. Finally, hoist the lifting tools to the ground to install the next corrugated sheet.

[0037] It should be noted that the load-bearing beam of the lifting tool 1 is welded from channel steel, and the internal supports are connected using channel steel to enhance the strength and stability of the lifting tool 1.

[0038] Please see Figure 2 An efficient and safe adjusting clamp for installing corrugated sandwich roof panels, used to assist in an efficient and safe method for installing corrugated sandwich roof panels, including a clamp body 5;

[0039] The clamp body 5 includes a mounting part 51, a connecting part 52, a supporting part 53, and a pressing part 54; the connecting part 52 is mounted on the mounting part 51 and is connected to the sling (the connecting part 52 is equipped with a lifting lug); the supporting part 53 is mounted on the mounting part 51, and the pressing part 54 is hinged to the mounting part 51. The pressing part 54 and the supporting part 53 cooperate to clamp the corrugated sheet; the mounting part 51 is provided with a fixing part 514, which is used to fix the pressing part 54 so that it will not rotate automatically (the fixing part 514 refers to a screw, nut, or pin, etc., that can fix the pressing part 54 so that it will not rotate and can be removed); the pressing part 54 has a groove 55 on the side facing the supporting part 53, and the groove 55 fits with the protrusion on the surface of the corrugated sheet;

[0040] It should be noted that the adjustment clamp is used as follows: remove the fixing part 514, then rotate the pressing part 54 to unfold it, then move the adjustment clamp so that the pressing part 54 and the supporting part 53 are respectively on the upper sides of the corrugated plate. Next, rotate the pressing part 54 so that the protrusion on the upper surface of the corrugated plate is in the groove 55. Then, use the fixing part 514 to fix the pressing part 54, thereby installing the adjustment clamp on one side of the corrugated plate.

[0041] Please see Figure 2 , Figure 3 and Figure 4 A groove 512 is provided in the groove 55, and a contact 56 is slidably provided in the groove 512. An elastic element is installed between the groove 512 and the contact 56. A second touch switch is provided in the groove 512. A connecting groove is provided on the mounting member 51, and a mounting block 521 is provided on the connecting member 52. The mounting block 521 is inserted into the connecting groove. A socket 522 is provided on the mounting block 521, and a secondary telescopic member is provided in the connecting groove. The moving end of the secondary telescopic member is inserted into the socket 522. The secondary telescopic member is electrically connected to the second touch switch.

[0042] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 The support member 53 has a mounting groove 57 on the side facing the pressing member 54. A movable member 58 is slidably mounted in the mounting groove 57. An elastic element is installed between the mounting groove 57 and the movable member 58. A first touch switch 513 is provided in the mounting groove 57. When the movable member 58 moves toward the pressing member 54 (i.e., the movable member 58 loses pressure and moves upward under the action of the elastic element), the movable member 58 will press the first touch switch 513. A main telescopic member 59 is provided in the connecting groove. A hole is opened on the mounting block 521. The movable end of the main telescopic member 59 is inserted into the hole to fix the mounting block 521 in the connecting groove. The main telescopic member 59 is electrically connected to the first touch switch 513.

[0043] Please refer to Figure 3 The main telescopic component 59 and the auxiliary telescopic component have the same structure, both including a kit 591, a rod 592 that slides into the kit 591, a spring component (the elastic component is not affected by magnetic attraction, such as rubber) installed between the rod 592 and the kit 591, and an electromagnet installed in the kit 591 (the first touch switch 513 and the second touch switch are electrically connected to the electromagnet at the corresponding positions). The end of the rod 592 facing the electromagnet is provided with a magnetic block (the magnetic block and the electromagnet on the opposite side have the same magnetic poles, and they will generate a repulsive force when they come close to each other).

[0044] It should be noted that when the lifting tool 1 loosens the corrugated sheet, and the adjusting clamp is still fixed on one side of the corrugated sheet, if the adjusting clamp is unstable during the process of lifting the outer side of the corrugated sheet using the adjusting clamp, causing the corrugated sheet to move, the movement of the corrugated sheet will cause the protrusion of the corrugated sheet to move out of the groove 55, causing the contact 56 to move outward instead of contacting the protrusion of the corrugated sheet, causing the second touch switch to disappear under the pressure of the contact 56; this will de-energize the electromagnet in the auxiliary telescopic component, and under the action of the elastic component, the insertion rod 592 here will move into the kit 591 and move out of the insertion hole 522; and because the corrugated sheet begins to move, at this time the corrugated sheet... Since the corrugated plate has not been completely removed from the adjusting clamp, it will still press against the moving part 58, causing the moving part 58 to not contact the first touch switch 513, thus de-energizing the main telescopic part 59 (i.e., the electromagnet here is de-energized, so the insertion rod 592 is not inserted into the hole); thus, the mounting block 521 is disconnected from the connecting groove, so that when the sling lifts the adjusting clamp, it will only move the connecting part 52, while the mounting part 51 will not continue to move; that is, when the corrugated plate begins to loosen and fall, the mounting part 51 of the adjusting clamp separates from the connecting part 52, preventing the lifting from continuing to move the corrugated plate and causing it to fall, thus increasing the safety of the lifting.

[0045] When the adjusting clamp is not in use (the adjusting clamp is not fixed on the corrugated plate), under the action of the elastic element, the contact 56 moves outward and does not contact the second touch switch, so that the secondary telescopic member does not fix the mounting block 521; under the action of the elastic element, the moving member 58 moves upward and presses the first touch switch 513, so that the main telescopic member 59 is energized (that is, the electromagnet here is energized, pushing the plug rod 592 to move and insert into the air), fixing the mounting block 521 in the connecting groove, so that the mounting member 51 is connected to the connecting member 52.

[0046] When adjusting the clamp, the pressing member 54 and the support member 53 come into contact with the corrugated plate, which will press the contact member 56 into the slot 512, causing the contact member 56 to press the second touch switch, which will energize the auxiliary telescopic member and fix the mounting block 521 in the connecting slot; while the corrugated plate comes into contact with the support member 53, which will push the moving member 58 into the mounting slot 57, so that it does not come into contact with the first touch switch 513, and disconnects the connection between the main telescopic member 59 and the mounting block 521.

[0047] In this embodiment, as a further optimization, please refer to... Figure 3A push rod 511 is slidably provided on the secondary telescopic component, and a connecting rope 510 is provided between the push rod 511 and the pressing component 54. During the process of removing the adjustment clamp, the fixing component 514 is removed first, and then the pressing component 54 is rotated. During this process, the contact component 56 will not contact the corrugated plate, while the corrugated plate and the moving component 58 will still be in contact (the mounting component 51 and the connecting component 52 may be disconnected). However, when the pressing component 54 is rotated, it will pull the connecting rope 510, move the push rod 511, and insert the insertion rod 592 into the insertion hole 522 to fix the mounting block 521, so that the mounting component 51 and the connecting component 52 will not separate during the normal removal of the adjustment clamp.

[0048] In this embodiment, as a further optimization, please refer to... Figure 2 and Figure 4 The pressing member 54 includes a mounting arm 541 hinged to the mounting member 51 and a pressing arm 542. The mounting arm 541 has a mounting groove on the side away from the mounting member 51. A rod is mounted on the side of the pressing arm 542 facing the mounting arm 541, and the rod slides into the mounting groove. The length of the pressing member 54 can be adjusted by the sliding of the rod within the mounting groove. Bolts are screwed onto the mounting arm 541 to fix the rod. A sliding groove is provided on the side of the pressing arm 542 facing the rod, and the rod slides into the sliding groove, allowing the pressing arm 542 to move (towards or away from the support member 53). Bolts are mounted on the pressing arm 542 to fix the moved pressing arm 542. By changing the distance between the pressing member 54 and the support member 53, the pressing member 54 and the support member 53 can cooperate to clamp the corrugated sheet.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
