Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an attachment steel frame suitable for curved construction elevators. Background Technology

[0002] Construction elevators are widely used in construction sites such as buildings, bridges, and power plants due to their convenience.

[0003] A search revealed Chinese patent CN221295819U, which discloses a construction elevator attachment frame. Key technical features include: a main guide rail mechanism for vertical movement of the construction elevator; a steel platform for supporting construction equipment; an attachment mechanism for driving the steel platform to move vertically on the main guide rail mechanism; one end of the attachment mechanism is movably mounted on the main guide rail mechanism, and the other end is connected to the steel platform; and a fixed wall attachment for auxiliary positioning of the attachment mechanism; the fixed wall attachment is mounted on the main guide rail mechanism. This patent has the advantage that the attachment mechanism can slide on the main guide rail mechanism to avoid repeated disassembly and reassembly.

[0004] In the aforementioned existing technical solutions, the main rail mechanism is directly installed on the external wall and is vertical. However, during bridge construction, many bridge piers are designed as irregular cross-section structures with curved lower parts. Therefore, the aforementioned existing technical solutions may not be able to adapt to the shape of the piers in actual use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes an attachment steel frame suitable for curved construction elevators. By distributing multiple chords in an inclined platform shape, the multiple chords can change synchronously with the inclination of the side wall of the pier. By fixing crossbars to the side wall of the chords, the data is finally transmitted to the pier, ensuring the stability of the attachment steel frame and adapting to the construction environment.

[0006] The technical solution to achieve the purpose of this utility model is as follows: an attached steel frame suitable for curved construction elevators, including two connecting rods, the two ends of which are fixedly connected to external bridge piers. Multiple chords are provided on the rear side walls of both connecting rods, and the multiple chords are distributed in a truncated pyramid shape. An elevator guide rail mechanism is provided on the outside of the two connecting rods. The elevator guide rail mechanism is installed on the side wall of the chords. Connecting bolts are fixedly installed on the side wall of the multiple chords away from the connecting rods. A positioning plate is provided on the end of the connecting bolt away from the chord. A fixed crossbar is fixedly installed on the side wall of the two connecting rods that are close to each other. The end of the chord near the connecting rod is fixedly installed on the side wall of the close fixed crossbar.

[0007] In some embodiments, a connecting block is fixedly installed on the side wall of the chord, and a reinforcing plate is provided at the bottom of the connecting block.

[0008] In some embodiments, two reinforcing bolts are threaded onto the sidewall of the reinforcing plate, and the two reinforcing bolts are threaded onto the sidewalls of adjacent connecting blocks and connecting rods, respectively, through the sidewall of the reinforcing plate.

[0009] In some embodiments, the elevator guide rail mechanism includes two slide rails disposed outside the connecting rod. Multiple connecting crossbars are fixedly installed at the end of the sidewalls of the two slide rails that are close to each other, and reinforcing rods are fixedly installed at the end of the sidewalls of the two slide rails that are close to the fixed crossbars.

[0010] In some embodiments, both the reinforcing rod and the connecting crossbar have threaded fixing bolts that are mounted on the sidewalls of the fixed crossbar.

[0011] Compared with the prior art, the significant advantages of this utility model are:

[0012] Firstly, this utility model involves pre-embedding positioning plates at predetermined positions on the bridge piers during construction. Once the concrete near the positioning plates reaches the required strength, connecting bolts are used to connect and fix them to the adjacent positioning plates. By distributing multiple chords in an inclined platform shape, the chords can synchronously change with the inclination of the sidewalls of the bridge piers. By fixing crossbars to the sidewalls of the chords, the weight of the elevator guide rail mechanism is transferred to the chords, then to the connecting rods, and finally to the bridge piers. This ensures the stability of the attached steel frame and allows it to adapt to the construction environment, thus solving the problem that existing attached steel frames cannot adapt to the construction environment.

[0013] Secondly, this utility model connects the connecting block and the connecting rod together by means of a reinforcing plate, so that the reinforcing plate can support the chord, improve the strength of the chord, and achieve the effect of ensuring the stability of the chord position.

[0020] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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 protection scope of the present invention.

[0021] This utility model provides an improved attachment steel frame suitable for curved construction elevators. The technical solution of this utility model is as follows:

[0022] like Figures 1-3 As shown, an attached steel frame suitable for curved construction elevators includes two connecting rods 1, both ends of which are fixedly connected to external bridge piers. Multiple chord members 2 are provided on the rear sidewalls of both connecting rods 1, arranged in a truncated pyramid shape. An elevator guide rail mechanism is provided on the outside of the two connecting rods 1, mounted on the sidewalls of the chord members 2. Connecting bolts 3 are fixedly installed on the sidewalls of the multiple chord members 2 away from the connecting rods 1. Positioning plates 4 are provided on the ends of the connecting bolts 3 away from the chord members 2. Fixed crossbars 6 are fixedly installed on the sidewalls of the two connecting rods 1 adjacent to each other. The ends of the chord members 2 closest to the connecting rods 1 are fixedly installed on the sidewalls of the adjacent fixed crossbars 6. First, during the construction of the bridge piers, the positioning plates 4 are pre-embedded in predetermined positions on the bridge piers. After the concrete near the positioning plates 4 reaches the required strength, the connecting bolts 3 are connected and fixed to the adjacent positioning plates 4. By distributing multiple chord members 2 in an inclined platform shape, the multiple chord members 2 can change synchronously with the inclination of the side wall of the pier. By fixing crossbars 6 to the side wall of the chord members 2, the weight of the elevator guide rail mechanism is transferred to the chord members 2, then to the connecting rods 1, and finally to the pier, ensuring the stability of the attached steel frame. The elevator guide rail mechanism includes two slide rails 81 set outside the connecting rods 1. Multiple connecting crossbars 84 are fixedly installed at the end of the side wall of the two slide rails 81 that are close to each other. Reinforcing rods 83 are fixedly installed at the end of the side wall of the two slide rails 81 that are close to the fixed crossbars 6. Fixing bolts 82 threaded on the side wall of the fixed crossbars 6 are passed through the side wall of the reinforcing rods 83 and the side wall of the connecting crossbars 84. The elevator guide rail mechanism is installed on the side wall of the fixed crossbars 6 by fixing bolts 82, which facilitates the use of the elevator.

[0023] like Figures 1-3As shown, in one embodiment, in order to further improve the strength of the attached steel frame, a connecting block 9 is fixedly installed on the side wall of the chord 2, and a reinforcing plate 5 is provided at the bottom of the connecting block 9. Two reinforcing bolts 7 are threaded on the side wall of the reinforcing plate 5. The two reinforcing bolts 7 penetrate the side wall of the reinforcing plate 5 and are respectively threaded on the side walls of the adjacent connecting block 9 and connecting rod 1. The connecting block 9 and connecting rod 1 are connected together by the reinforcing plate 5, so that the reinforcing plate 5 can support the chord 2, improve the strength of the chord 2, and achieve the effect of ensuring the positional stability of the chord 2.

[0024] The specific working method is as follows: First, when constructing the bridge pier, the positioning plate 4 is pre-embedded in the predetermined position on the bridge pier. After the concrete strength near the positioning plate 4 reaches the required level, the connecting bolt 3 is connected and fixed to the adjacent positioning plate 4. By distributing multiple chord members 2 in an inclined platform shape, the multiple chord members 2 can change synchronously with the inclination of the side wall of the bridge pier. By fixing and installing the fixed crossbar 6 on the side wall of the chord member 2, the weight of the elevator guide rail mechanism is transferred to the chord member 2, and then transferred to the connecting rod 1 through the chord member 2, and finally transferred to the bridge pier, ensuring the stability of the attached steel frame position.

[0025] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
