[0002] In the construction of steel structure buildings, the precise assembly of hoisting structures such as beams is a major challenge. The assembly of beams requires external hoisting equipment to lift the beam frame, and then precisely align the connecting ends of the beam frame with the positions to be assembled. During the hoisting and alignment process, the beam frame may sway or rotate after being lifted, making it impossible for it to align itself automatically. Operators must closely monitor the process to ensure the necessary connections are correct. Then, operators use bolts, nuts, and other fasteners to secure the aligned components. The entire process requires manual intervention, making the alignment cumbersome and posing safety hazards such as crushing and pinching injuries. Therefore, a structure capable of rapid alignment and installation is needed to optimize the construction of steel structure buildings. Summary of the Invention

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] A quick-installation structure for a hoisting bracket includes a support base 1, an insert plate 2, an adjustment component 3, and two locking claws 4. The support base 1 is fixedly connected to the side of a column 6, and the insert plate 2 is fixedly connected to the end of a crossbeam 5. The support base 1 is provided with an insertion slot 16, and the two locking claws 4 are symmetrically arranged and hinged in the insertion slot 16. The insert plate 2 is inserted into the insertion slot 16 and placed between the two locking claws 4. The adjustment component 3 is slidably inserted into the insertion slot 16, and the two pushing claws 32 of the adjustment component 3 push against the side of the two locking claws 4 away from the insert plate 2.

[0022] The insert plate 2 is preferably fixed at the end of the crossbeam 5 by welding. The support seat 1 is preferably fixed at the height where the crossbeam 5 needs to be erected on the side of the column 6 by welding. The insert plate 2 is inserted into the insertion slot 16. The two locking claws 4 work together to hold the insert plate 2. The adjusting component 3 pushes the two locking claws 4 to keep it upright and stably hold the insert plate 2. The insert plate 2 is inserted into the support seat 1, thus realizing the alignment and connection between the crossbeam 5 and the column 6.

[0023] The lower end of the insert plate 2 has a downward protruding insert piece 21. The insert piece 21 has recessed locking grooves 23 on both sides in the width direction. The locking claws 4 are respectively inserted into the two locking grooves 23. When the insert plate 2 is inserted into the insertion slot 16, the insert piece 21 passes through the gap between the two locking claws 4, and the locking claws 4 are respectively inserted into the two locking grooves 23.

[0024] The lower ends of the two side faces of the insert 21 are inclined to form two sloping surfaces. The tops of the two locking claws 4 are also provided with sloping surfaces. The two sloping surfaces are located on the side of the locking claws 4 close to the insert 21. The two sloping surfaces are inclined from top to bottom towards the insert 21. When the insert 21 is inserted into the insertion slot 16 from top to bottom, the two sloping surfaces of the insert 21 first contact the sloping surfaces of the two locking claws 4 respectively. The insert 21 continues to be inserted, pushing the two locking claws 4 to rotate and expand the distance. When the insert 21 is inserted into the bottom position, the two locking claws 4 return to the neutral position and the two claws are respectively inserted into the two locking slots 23.

[0025] Each of the locking claws 4 is fixedly equipped with a spring plate 41. The working end of the spring plate 41 points to the insert plate 21 and is curved in an arc shape. The mounting end of the spring plate 41 is straight. The mounting end of the spring plate 41 is fixedly installed on the bottom surface of the locking claw 4 by fastening bolts. The working end of the spring plate 41 abuts against the two sloping surfaces at the lower end of the insert plate 21 respectively.

[0026] Each locking claw 4 has its claw located at the top of the side wall facing the insert 21. Each locking claw 4 has a through hole. The through hole is eccentrically positioned and extends through the thickness direction of the locking claw 4. The eccentrically positioned through hole allows the locking claw 4 to maintain a naturally vertical neutral position under the force of gravity after assembly. That is, when the insert 21 is not inserted into the insertion slot 16, the two locking claws 4 can remain vertical and avoid flipping.

[0027] When the locking claw 4 is in the neutral position, the side of the locking claw 4 away from the insert 21 is tilted from top to bottom away from the insert 21, and the pushing claw 32 is clamped between the locking claw 4 and the side wall of the insertion slot 16.

[0028] The mounting base 1 includes a back plate 11 and a front baffle 15. The back plate 11 is fixedly mounted on the side of the column 6, and the front baffle 15 is fixedly mounted on the side of the back plate 11 facing the crossbeam 5. The front baffle 15 and the back plate 11 form an insertion groove 16. Two guide grooves 13 are opened vertically on the side of the front baffle 15 facing the back plate 11. The two guide grooves 13 are parallel to each other. The lower end of each of the two guide grooves 13 is provided with a hinge hole that passes through the front baffle 15. The locking claw 4 is rotatably mounted on the hinge hole by a pin. Each of the locking claws 4 has a protruding annular boss on the front side of the front baffle 15. The two bosses are respectively embedded in the two guide grooves 13.

[0029] The lower end walls of the two guide grooves 13 are both machined into an arc shape coaxial with the hinge hole. When assembling the locking claws 4, both locking claws 4 are placed in the insertion slot 16, and the two bosses are aligned with the two guide grooves 13 and slid into the insertion slot 16.

[0030] The adjustment assembly 3 includes a gripping rod 31, two pushing claws 32, and two return springs 33. The bottom of the insertion slot 16 has two through-holes 14. The lower ends of the two pushing claws 32 are integrally provided with connecting rods. The bottom of the insertion slot 16 has two through-holes 14. The connecting rods of the two pushing claws 32 are respectively inserted into the two through-holes 14. The two return springs 33 are respectively fitted on the two connecting rods and located between the pushing claws 32 and the bottom of the insertion slot 16. The gripping rod 31 is fixedly connected to the two connecting rods outside the support base 1.

[0031] The push claw 32 is wider at the top and narrower at the bottom. The side edge of the push claw 32 that abuts against the locking claw 4 is arc-shaped. When the push claw 32 is pulled down, the wide head of the push claw 32 slides down and pushes the locking claw 4 to rotate around the hinge axis, thereby causing the locking claw 4 to disengage from the locking groove 23, so that the insert 21 can be restored to a free state, making it easy to disassemble the crossbeam 5 and the column 6.

[0032] The lower end of the insert plate 2 protrudes from the lower surface of the crossbeam 5. A reinforcing rib 22 is fixedly provided between the insert plate 2 and the lower surface of the crossbeam 5. An alignment groove 12 is provided on the front baffle 15 at the position where it aligns with the reinforcing rib 22. The insert piece 21 is inserted into the insertion groove 16, and the reinforcing rib 22 is inserted into the alignment groove 12.

[0033] The back plate 11 and the insert plate 2 are aligned and connected by connecting holes. The insert plate 2 is inserted into the support base 1 and fastened by multiple fixing bolts 7. When the insert piece 21 is inserted into the insertion slot 16, the connecting holes on the insert plate 2 and the back plate 11 are aligned. At this time, the multiple fixing bolts 7 are screwed between the support base 1 and the insert plate 2 to complete the fixed connection.

[0034] Working principle: When aligning and assembling the crossbeam 5 and the column 6, insert the insert 21 into the insertion slot 16. Once the insert 21 is fully inserted into the insertion slot 16, the claws of the two locking claws 4 will be inserted into the two locking slots 23 to lock the insert 21. At the same time, since the two locking claws 4 are symmetrically arranged, the insert 21 is located in the center of the insertion slot 16. At this time, the multiple fixing bolts 7 can be installed to align and fix the crossbeam 5 and the column 6.

[0035] This installation structure allows for quick disassembly. When the crossbeam 5 needs to be removed from the column 6, multiple fixing bolts 7 are removed, and then the grab rod 31 is pulled down to cause the two push claws 32 to slide downwards and compress the return spring 33. At this time, the wide head at the upper end of the push claw 32 slides down and pushes the locking claw 4 to rotate. The claw of the rotated locking claw 4 disengages from the locking groove 23. Then, the crossbeam 5 is lifted up to pull the insert 21 out of the insertion slot 16.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
