DETAILED DESCRIPTION

[0025] The following describes embodiments of the present application in more detail with reference to the accompanying drawings. Although the accompanying drawings illustrate embodiments of the present application, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0026] There is a technical problem that the installation of cantilever beam 2 requires the cooperation of lifting equipment, which makes the installation procedure complicated and the operation difficult for the staff.

[0027] To this end, the present application provides an adjustable cantilever scaffolding, comprising a first connecting seat 1, a suspension beam 2, a second connecting seat 3, a diagonal brace 4, a third connecting seat 5, and a diagonal brace 6; the suspension beam 2 is made of I-beam, and the first connecting seat 1, the second connecting seat 3, and the third connecting seat 5 are thick steel plates with pre-set connection holes; during installation, expansion bolts are inserted through the connection holes into the shear wall, thereby firmly connecting the steel plates to the shear wall, that is, firmly connecting the first connecting seat 1, the second connecting seat 3, and the third connecting seat 5 to the shear wall. The first connecting seat 1 is located in the middle, the second connecting seat 3 is fixedly mounted below the first connecting seat 1, and the third connecting seat 5 is fixedly mounted above the first connecting seat 1.

[0028] The first connecting base 1 is provided with a connecting sleeve 7, which is integrally formed with the first connecting base 1 to improve the structural strength of both. The connecting sleeve 7 is installed vertically, and a clamping groove 701 is provided at the upper end of the connecting sleeve 7; an extension portion 205 is provided at the top of one end of the suspension beam 2, and a hinge shaft 206 and a clamping block 201 extending vertically downward are provided on the bottom surface of the extension portion 205;

[0029] During installation, the hinge shaft 206 is inserted into the connecting sleeve 7 from top to bottom, and the first connecting seat 1 and the suspension beam 2 are hinged through the hinge shaft 206 and the connecting sleeve 7, so that the suspension beam 2 can rotate in the horizontal direction. When installing the suspension beam 2, the first connecting seat 1 is first installed on the shear wall, and then the hinge shaft 206 is inserted into the connecting sleeve 7. During the insertion process, the staff can stand on the building and install the suspension beam 2 in a posture parallel to the shear wall, and then rotate the suspension beam 2 to make it rotate to a direction perpendicular to the shear wall. Compared with the method of building a hoisting mechanism for installation, the suspension beam 2 of this application is more convenient to install.

[0030] When the cantilever beam 2 rotates to a direction perpendicular to the shear wall, the clamping block 201 is embedded in the clamping groove 701, thereby limiting the position of the cantilever beam 2 and ensuring the stability of the cantilever beam 2 structure.

[0031] One end of the diagonal brace 4 is hinged to the second connecting seat 3, and the other end is connected to the bottom surface of the suspension beam 2. The diagonal brace 4, the shear wall and the suspension beam 2 form a triangular structure to improve the overall structural strength of the scaffolding.

[0032] One end of the diagonal brace 6 is connected to the third connecting seat 5, and the other end is connected to the top surface of the suspension beam 2. The diagonal brace 6, the shear wall and the suspension beam 2 form a triangular structure, which further improves the overall structural strength of the scaffolding.

[0033] In some specific embodiments, a rotating seat 301 is provided on the second connecting seat 3, and the lower end of the diagonal support rod 4 is hinged to the rotating seat 301, so that the diagonal support rod 4 can rotate in the vertical direction. In this way, when the diagonal support rod 4 needs to be installed, you can stand indoors, first insert one end of the diagonal support rod 4 on the rotating seat 301, and then rotate the diagonal support rod 4 upward until the upper end of the diagonal support rod 4 is against the lower side of the suspension beam 2, which makes the installation of the diagonal support rod 4 more convenient.

[0034] In this embodiment, a stop block 202 that can move left and right is movably installed at the bottom of the suspension beam 2, and the upper end of the diagonal support rod 4 is hinged to the stop block 202; a connecting block 203 fixedly connected to the suspension beam 2 is provided on the right side of the stop block 202, and a locking bolt 204 is threaded on the connecting block 203, and the left end of the locking bolt 204 is hinged to the stop block 202.

[0035] When installing the diagonal brace 4, rotate the diagonal brace 4 upward so that its upper end contacts the bottom surface of the suspension beam 2, then hinge the diagonal brace 4 with the block 202, and then rotate the locking bolt 204. The locking bolt 204 pushes the block 202 and the upper end of the diagonal brace 4 to the left, so that the upper end of the diagonal brace 4 and the suspension beam 2 are firmly connected. Compared with welding or bolting the diagonal brace 4 to the suspension beam 2, the installation of the diagonal brace 4 is more convenient, and the diagonal brace 4 can give the suspension beam 2 a certain pre-support force, effectively reducing the amount of downward deformation of the suspension beam 2 when it is under pressure.

[0036] In some specific embodiments, the inclined rod 6 includes a first connecting segment 601 and a second connecting segment 602, one end of the first connecting segment 601 is hinged to the third connecting seat 5, and the outer circumferential surface of the other end is provided with a thread; one end of the second connecting segment 602 is hinged to the suspension beam 2, and the outer circumferential surface of the other end is provided with a thread; one end of the connecting member 8 is threadedly connected to the first connecting segment 601, and the other end is threadedly connected to the second connecting segment 602, and the threads on the first connecting segment 601 and the second connecting segment 602 are screwed in opposite directions.

[0037] Specifically, one end of the first connecting section 601 hinged to the third connecting seat 5 is hook-shaped, and a horizontally arranged through hole is provided on the third connecting seat 5; one end of the second connecting section 602 hinged to the suspension beam 2 is T-shaped, and a square through hole is provided on the suspension beam 2.

[0038] When installing the diagonal brace 6, first insert the end of the first connecting section 601 with the hook into the through hole on the third connecting seat 5, so that the two are hinged together, then insert the T-shaped end of the second connecting section 602 into the through hole on the suspension beam 2, so that the two are hinged together, and finally connect the first connecting section 601 and the second connecting section 602 with one end having threads through the connecting piece 8, thereby realizing the assembly of the diagonal brace 6, wherein the first connecting section 601 and the second connecting section 602 can be moved closer to or separated from each other by rotating the connecting piece 8, thereby adjusting the total length of the diagonal brace 6, so that the diagonal brace 6 can have a certain pre-tension on the suspension beam 2, and the cantilever scaffolding is more compact after assembly.

[0039] The embodiments of the present application have been described above. The above description is illustrative and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is selected to best explain the principles of the embodiments, their practical applications, or improvements to the technology in the market, or to enable other persons skilled in the art to understand the embodiments disclosed herein.
