Description

Technical Field

[0001] This utility model relates to the technical field of scaffolding, and in particular to a cantilever scaffolding device for H-beam steel beams. Background Technology

[0002] Traditional cantilevered steel beams must pass through the building's exterior walls, extend into the interior, and be laid on the main structural floor. They are then anchored to the floor slab and floor beams using three U-shaped embedded parts. The steel beams passing through the walls can easily damage the concrete beams and slabs, leading to floor seepage and leaks. Furthermore, the upper end of the H-beams cannot be welded to leave a weld seam, making it impossible to directly weld the embedded bolts to the upper end of the beams. The connection method between conventional H-beams and embedded bolts is also quite complex, requiring a large amount of work for disassembly and assembly, and resulting in high installation costs. Utility Model Content

[0003] In view of the shortcomings and defects of the existing technology, a cantilever scaffolding device for H-shaped steel beams is provided. In order to achieve the purpose of better connecting the cantilever frame, the present invention provides the following technical solution.

[0004] A cantilever scaffolding device for H-beams includes a cantilever frame, an H-beam, and embedded bolts. The H-beam is installed within a concrete wall. The embedded bolts are installed on the flanges of the H-beam. Several rivets are provided on the flanges of the H-beam. Reinforcing bars are provided between the embedded bolts and the rivets, and the reinforcing bars are vertically positioned on the embedded bolts and fixedly connected to them. One end of the embedded bolt extends out of the concrete wall. The cantilever frame is fitted with the embedded bolt and fixed to the outside of the concrete wall by nuts. Scaffolding is erected on the upper surface of the cantilever frame.

[0005] Compared with the prior art, this utility model has a better fixed bolt by setting a pre-embedded bolt at the upper end of the steel beam and setting a steel bar on the pre-embedded bolt. The steel bar is set perpendicular to the pre-embedded bolt, and the pre-embedded bolt can be fixed better by fixing the steel bar to the pre-embedded bolt. This makes the connection between the pre-embedded bolt and the cantilever frame more stable and improves the overall connection strength. At the same time, the overall structure is simple and the manufacturing cost is low.

[0006] Furthermore, the rivet components are symmetrically arranged on the flanges of the H-beam steel beam. Each rivet component includes a rivet head and a rivet post, and the diameter of the rivet head is larger than the diameter of the rivet post. The reinforcing bars are fitted between the embedded bolts and the rivet head.

[0007] With the above improvements, the rivets are respectively set on the flanges of the steel beam, which can facilitate better bonding with the concrete during concrete pouring. The rivet components include rivet joints and rivet posts. The diameter of the rivet joint is larger than the diameter of the rivet post. The reinforcing bars cannot slide out of the rivet components in the vertical direction, so that the rivet components can form a preliminary limit on the reinforcing bars, allowing the reinforcing bars to be better positioned between the rivet joints and the pre-embedded bolts.

[0008] Furthermore, the reinforcing bar abuts against the riveted post, and the abutment of the reinforcing bar and the riveted post is fixedly connected by welding, while the connection between the reinforcing bar and the pre-embedded bolt is fixed by spot welding.

[0009] Through the above improvements, the rebar and the rivet post abut against each other, the abutment of the rebar and the rivet post is fixed by welding, and the abutment of the rebar and the embedded bolt is fixed by spot welding. This can better fix the embedded bolt to the steel beam and make the connection of the embedded bolt more stable when it is fixed.

[0010] Furthermore, the embedded bolt is U-shaped and includes a fixing section and a connecting section. The fixing section is located on the end face of the H-beam flange, and the connecting section is threaded and located on the outside of the concrete wall.

[0011] With the above improvements, the pre-embedded bolts include a fixing section and a connecting section. The fixing section is set on the flange of the steel beam, and the connecting section extends out of the concrete wall and is set in conjunction with the cantilever frame to facilitate the fixing of the cantilever frame.

[0012] Furthermore, the cantilevered steel section includes an I-beam and a pad. The pad is disposed at the end of the I-beam near the concrete wall. The pad is fitted with the connecting section and is fixed to the concrete wall by a nut thread.

[0013] Through the above improvements, a pad is installed on the section of the cantilever frame near the concrete wall. The pad is fitted with the connecting section protruding from the concrete wall and fixed by a nut thread, which enables the cantilever frame to be fixed better and improves the stability of the connection.

[0014] Furthermore, structural reinforcement bars are laid inside the concrete wall on the side closest to the cantilever frame.

[0015] With the above improvements, structural reinforcement bars are laid inside the concrete wall on the side closest to the cantilever frame, which facilitates the pouring of the concrete wall. Attached Figure Description

[0023] like Figures 1 to 4 The cantilever scaffolding device for an H-beam 2 shown includes a cantilever frame 1, an H-beam 2, and embedded bolts 3. The H-beam 2 is set inside a concrete wall 4. The embedded bolts 3 are installed on the flanges of the H-beam 2. Several rivets 2.1 are provided on the flanges of the H-beam 2. Reinforcing bars 5 are provided between the embedded bolts 3 and the rivets 2.1. The reinforcing bars 5 are vertically set on the embedded bolts 3 and fixedly connected to the embedded bolts 3. One end of the embedded bolts 3 extends out of the concrete wall 4. The cantilever frame 1 is set in conjunction with the embedded bolts 3 and fixed to the outside of the concrete wall 4 by nuts 6. Scaffolding is erected on the upper surface of the cantilever frame 1.

[0024] The H-beam 2 is integrally set inside the concrete wall 4. Several rivets 2.1 are provided on the upper end of the flange of the H-beam 2. The rivets 2.1 are symmetrically arranged on both sides of the flange of the H-beam 2. When the concrete wall 4 is poured, the H-beam 2 and the concrete wall 4 can be better connected. Furthermore, structural reinforcement 7 is laid on the side of the concrete wall 4 near the cantilever frame 1, which makes the concrete wall 4 more solid when it is poured.

[0025] The rivet 2.1 includes a rivet head 2.11 and a rivet post 2.12. The diameter of the rivet head 2.11 is larger than the diameter of the rivet post 2.12, so that an installation space is formed between the rivet head 2.11 and the pre-embedded bolt 3. The reinforcing bar 5 is placed in the installation space, so that the reinforcing bar 5 cannot slide out of the rivet 2.1 in the vertical direction, so that the rivet 2.1 can form a preliminary limit on the reinforcing bar 5.

[0026] The embedded bolts 3 installed on the flange of the H-beam 2 are U-shaped. The embedded bolts 3 include a fixing section 3.1 and a connecting section 3.2. The lower end of the fixing section 3.1 abuts against the flange of the H-beam 2, and the reinforcing bar 5 abuts against the upper end face of the fixing section 3.1. The abutting point of the reinforcing bar 5 and the fixing section 3.1 is fixedly connected by spot welding. The reinforcing bar 5 also abuts against the riveting post 2.12 of the rivet 2.1, and the abutting point of the reinforcing bar 5 and the riveting post 2.12 is fixedly connected by welding. This allows the fixing section 3.1 of the embedded bolts 3 to be well fixed on the flange of the H-beam 2 without direct welding to the H-beam 2, which complies with the regulations.

[0027] The connecting section 3.2 of the pre-embedded bolt 3 extends out of the concrete wall 4 to cooperate with the cantilever frame 1, and the connecting section 3.2 is provided with threads. The cantilever frame 1 includes an I-beam 1.1 and a pad 1.2. The I-beam 1.1 is set horizontally, and the pad 1.2 is set at the end of the I-beam 1.1 near the concrete wall 4. The pad 1.2 is provided with a mating through hole, the connecting section 3.2 passes through the mating through hole, the pad 1.2 is set on the concrete wall 4, and is threadedly engaged with the connecting section 3.2 by a nut 6, so that the cantilever frame 1 can be fixed on the concrete wall 4.
