Description

Technical Field

[0001] The utility model relates to an auxiliary device, in particular to an auxiliary device which is used for temporarily stacking steel supports and can be used for hoisting steel supports. Background Art

[0002] Steel support is one of the important measures to ensure the stability of deep foundation pits. At the construction site, the temporary stacking of steel supports and the installation of steel supports are the key control contents of the construction site. After the steel supports are brought into the site, measures should be taken to ensure that the temporary stacking of the steel supports is stable; during the lifting of the steel supports, it should be ensured that the steel supports are lifted stably to the installation position. In actual work, after the steel supports are brought into the site, they are generally stacked and temporarily fixed with pads and triangular wedges. The effect of temporarily fixing the steel supports with triangular wedges is poor and more dangerous. When lifting the steel supports, the slings are generally directly put on both ends of the steel supports, and then the steel supports are lifted to the installation position by the slings. Since the slings are put on the ends of the steel supports, the stability is poor, and there are risks in the lifting process of the steel supports. Summary of the invention

[0020] Please refer to Figure 3When the lower structure (2) is used for temporarily stacking the steel support (A), the two lower structures (2) should be placed near the two ends of the steel support (A), and a number of pads (B) should be evenly arranged between the two lower structures (2) to support the steel support (A).

[0021] It should be noted that when temporarily stacking the steel supports (A), each steel support (A) should be provided with at least two of the lower structures (2), which are respectively placed near the two ends of the steel support (A). The lower structures (2) provided at the two ends of the steel support (A) can be used to hoist the steel support (A).

[0022] Please refer to Figure 4 When hoisting the steel support (A), the above-mentioned devices should be installed near both ends of the steel support (A).

[0023] Before the steel support (A) is hoisted, the upper structure (1) should be placed on the lower structure (2) so that the upper reinforcement plate (13) corresponds to the lower reinforcement plate (24) and the corresponding upper connection holes (14) and lower connection holes (25) overlap;

[0024] Then, after the bolt (31) is passed through the upper connection hole (14) and the lower connection hole (25) in sequence, the nut (32) is screwed onto the bolt (31), and two nuts (32) should be provided for each bolt (31);

[0025] The device is connected to the lifting equipment via a top lifting ring (12) and a lifting rope. The two ends of the lifting rope should be connected to two top lifting rings (12) respectively, so that the lifting rope is in a herringbone shape, and the top lifting ring (12) is connected to the lifting equipment.

[0026] Before lifting, check the installation of the bolts (31) and nuts (32), and the connection between the sling and the top lifting ring (12). After confirming that they are correct, lift and install the steel support (A) according to the steel support (A) lifting plan.

[0027] After the steel support (A) is hoisted, the devices at both ends of the installed steel support (A) should be removed in sequence. The specific method is as follows:

[0028] The device to be removed is connected to the lifting equipment through the top lifting ring (12) and the lifting rope, and the two ends of the lifting rope should be connected to the two provided top lifting rings (12) respectively, so that the lifting rope is in a herringbone shape, and the top lifting ring (12) is connected to the lifting equipment;

[0029] The base lifting rings (23) on both sides of the base (22) are connected to the lifting equipment respectively by using a lifting rope, and the two ends of the lifting rope should be connected to the two base lifting rings (23) provided on one side of the base (22) respectively, so that the lifting rope is in a herringbone shape, and the base lifting ring (23) on one side of the base (22) is connected to the lifting equipment;

[0030] Then, using a lifting device, the sling connected to the base lifting ring (23) is put into a tensioned state;

[0031] The bolts (31) and nuts (32) on one side of the device are removed, and then the sling on the side where the bolts (31) and nuts (32) are removed is slowly lowered, and the lower structure (2) is slowly opened and separated from the installed steel support (A), and at the same time, the sling on the side where the bolts (31) and nuts (32) are not removed is slowly raised according to the actual situation;

[0032] When the lower structure (2) can be completely separated from the installed steel support (A), the sling on the side where the bolts (31) and nuts (32) are not removed and the sling connected to the top lifting ring (12) should be lifted to completely separate the device from the installed steel support (A);

[0033] Finally, the device is hoisted to a safe area, the remaining bolts (31) and nuts (32) are removed, the upper structure (1) and the lower structure (2) are separated, and the upper structure (1), the lower structure (2), the bolts (31) and the nuts (32) are stored.

[0034] It should be noted that the top lifting ring (12) should be connected to the main lifting hook of the lifting device, and the base lifting ring (23) can be connected to the auxiliary lifting hook of the lifting device.

[0035] It should be noted that it is strictly forbidden to connect the base lifting ring (23) on one side of the base (22) and the base lifting ring (23) on the other side to the same hook at the same time; it is strictly forbidden to connect the sling connected to the top lifting ring (12) and the sling connected to the base lifting ring (23) on the side where the bolt (31) and the nut (32) are removed to the same hook at the same time.
