Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a hook-and-loop steel ladder for scaffolding. Background Technology

[0002] With the continuous development of the construction industry and the advancement of construction technology, the application scope and market size of disc-lock scaffolding, as a new type of construction scaffolding system, are constantly expanding. During construction, steel ladders play a crucial role in scaffolding erection and building construction, serving as vertical transportation facilities that facilitate workers' movement between different sections of the disc-lock scaffolding. However, in the use of disc-lock scaffolding, steel ladders are typically directly attached to the horizontal bars of the scaffolding. Due to their large size, conventional steel ladders are easily constrained by site conditions, making installation difficult and inefficient. Furthermore, their weight makes them difficult to move during installation and dismantling, severely impacting construction progress. For construction sites with limited space, the large footprint of the steel ladders makes their transport difficult, further hindering on-site construction progress. Utility Model Content

[0003] Therefore, this utility model aims to solve the problems of low installation efficiency and easy impact on construction progress in small construction sites of existing steel ladders used for scaffolding, and thus provides a hook-type steel ladder for scaffolding.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A hook-on steel ladder for scaffolding includes two ladder beams and a plurality of treads detachably installed between the two ladder beams, the treads being detachably installed on the ladder beams via connectors; hooks are provided at both ends of the two ladder beams, the hooks being adapted to install the steel ladder onto the scaffolding.

[0006] Furthermore, both ends of the pedal are provided with fixing members, which are installed on the ladder beam, and the pedal is detachably connected to the fixing members.

[0007] Furthermore, the fastener is an L-shaped angle steel, one side of which is adapted to be fixedly connected to the ladder beam, the other side of which extends toward another ladder beam, and the other side of which is adapted to place the tread.

[0008] Furthermore, an L-shaped hole is provided on the side of the L-shaped angle steel that connects to the ladder beam, and the connecting member is provided at both ends of the tread. The diameter of the end of the connecting member near the tread is adapted to the width of the L-shaped hole, and the diameter of the other end of the connecting member is greater than the width of the L-shaped hole.

[0009] Furthermore, the L-shaped angle steel has two L-shaped holes, and two connectors are provided at both ends of the pedal. The two connectors at the same end correspond one-to-one with the two L-shaped holes on the same L-shaped angle steel.

[0010] Furthermore, the connecting element is a connecting bolt.

[0011] Furthermore, the ladder beam is made of square steel, and the fastener is welded and fixed to the square steel.

[0012] Furthermore, the hook is welded and fixed to at least one side wall of the ladder beam.

[0013] Furthermore, hooks are provided at both ends of the ladder beam, and each hook is provided with a fastening structure.

[0014] Furthermore, a telescopic sleeve is fitted on at least one end of the ladder beam, and the telescopic sleeve is provided with the fixing member and a tread detachably connected to the fixing member on its side wall; multiple spaced insertion holes are provided on the ladder beam and the telescopic sleeve, and locking members are provided on the corresponding insertion holes on the ladder beam and the telescopic sleeve; the hook is welded and fixed to the telescopic sleeve.

[0015] The technical solution of this utility model has the following advantages:

[0016] 1. The hook-on steel ladder for scaffolding provided by this utility model features a detachable design where the ladder beams and treads are separated. When installing the steel ladder, the user only needs to first install the two ladder beams onto the scaffolding using hooks, and then install the treads onto the two ladder beams. This eliminates the need to transport the heavy and bulky steel ladder as a whole at once, and is not limited by the area of ​​the construction site. Even in construction sites with limited space, this detachable hook-on steel ladder can be easily and quickly brought to the site. It is also extremely convenient to move and disassemble when needed. When the hook-on steel ladder needs to be moved in a small area, it can be disassembled and reinstalled, avoiding the impact of moving the hook-on steel ladder on the construction progress.

[0017] 2. The hook-and-loop steel ladder for scaffolding provided by this utility model uses L-shaped angle steel as the fixing component. One side of the L-shaped angle steel is suitable for fixed connection with the ladder beam, and the other side of the L-shaped angle steel extends towards another ladder beam. The other side of the L-shaped angle steel is suitable for placing the treads. This design, using L-shaped angle steel as the fixing component, utilizes readily available materials on the construction site. In the event of missing or damaged fixing components, it is easy to quickly find alternative materials for replacement, which can significantly reduce material and construction costs.

[0018] 3. The hook-on steel ladder for scaffolding provided by this utility model has an L-shaped hole on the side where the L-shaped angle steel connects to the ladder beam. Connectors are provided at both ends of the treads. The diameter of the end of the connector near the tread matches the width of the L-shaped hole, while the diameter of the other end of the connector is larger than the width of the L-shaped hole. This design ensures the stability of the connection between the L-shaped angle steel and the ladder beam through the connectors. Simultaneously, the larger diameter of the other end of the connector allows for restraint, preventing the treads from loosening during use and ensuring the stability of the treads during operation.

[0019] 4. The hook-on steel ladder for scaffolding provided by this utility model has two L-shaped holes on the L-shaped angle steel, and two connectors at both ends of the tread. The two connectors at the same end correspond one-to-one with the two L-shaped holes on the same L-shaped angle steel. This arrangement, by setting corresponding L-shaped angle steels and L-shaped holes, ensures the stability of the connection between the L-shaped angle steel and the tread, preventing loosening and rotation during use.

[0020] 5. The hook-and-loop steel ladder for scaffolding provided by this utility model uses connecting bolts as the connecting parts. This design, using connecting bolts as the connecting parts, allows for pre-planning of gaps in the connecting bolts before installation, and then directly installing the steps onto the fixing parts by snapping in the connecting bolts, making installation faster and more convenient. Alternatively, after the steps are connected to the L-shaped angle steel, tightening the connecting bolts can make the connection between the steps and the L-shaped angle steel tighter, greatly improving the connection strength between the steps and the L-shaped angle steel.

[0021] 6. The hook-and-loop steel ladder for scaffolding provided by this utility model has square steel as the ladder beam, and the fasteners are welded and fixed to the square steel. This design, using square steel as the ladder beam, is a readily available material on construction sites. In the event of a missing or damaged ladder beam, it is easy to quickly find a replacement material, which can greatly reduce material and construction costs.

[0022] 7. The hook-and-loop steel ladder for scaffolding provided by this utility model has hooks at both ends of the ladder beam, and each hook has a fastening structure. This design can prevent the hook-and-loop steel ladder from accidentally coming loose during use, thus ensuring the safety of the hook-and-loop steel ladder during use.

[0023] 8. The hook-and-loop steel ladder for scaffolding provided by this utility model has a telescopic sleeve fitted on at least one end of the ladder beam. The telescopic sleeve has a fixing component and a detachable step connected to the fixing component on its side wall. Multiple spaced insertion holes are provided on the ladder beam and the telescopic sleeve, and locking components are provided on corresponding insertion holes on the ladder beam and the telescopic sleeve. Hooks are welded and fixed to the telescopic sleeve. This design maintains the connection stability between the ladder beam and the telescopic sleeve by providing locking components on the insertion holes. Simultaneously, the telescopic sleeve facilitates extending the length of the ladder beam, allowing the hook-and-loop steel ladder to adapt to scaffolding of greater height.

[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] like Figures 1-2 The illustrated hook-on steel ladder for scaffolding includes two ladder beams 1 and a plurality of treads 2 detachably installed between the two ladder beams 1. The treads 2 are detachably installed on the ladder beams 1 via connectors 6. Hooks 3 are provided at both ends of the two ladder beams 1, and the hooks 3 are adapted to install the steel ladder on the scaffolding.

[0033] This type of hook-and-loop steel ladder for scaffolding features a detachable design where the ladder beams 1 and treads 2 are separated. When installing the ladder, users simply attach the two ladder beams 1 to the scaffolding using hooks 3, and then attach the treads 2 to the two ladder beams 1. This eliminates the need to transport the heavy and bulky ladder as a whole, and avoids limitations imposed by the construction site area. Even in small construction sites, this detachable hook-and-loop steel ladder allows for quick and easy access. It is also extremely convenient to move and disassemble when needed. In smaller areas, the ladder can be disassembled and reassembled, preventing disruption to construction progress caused by moving the ladder.

[0034] In this embodiment, the ladder beam 1 is installed at an angle, and the tread 2 is installed horizontally on the ladder beam 1, that is, the angle between the ladder beam 1 and the tread 2 is less than 90°.

[0035] In this embodiment, a sound-absorbing structure is provided inside the step 2, which can effectively reduce noise when going up and down the steel ladder. Specifically, several anti-slip holes 8 are provided on the top of the step 2 to prevent people from slipping when going up or down the step 2. Specifically, both ends of the top of the step 2 are provided with protruding fixing steel plates 9, which can limit the movement of people when stepping on the steel plates and prevent them from slipping off the ends of the step 2 and causing accidents. Specifically, the fixing steel plates 9 are welded and fixed to the step 2.

[0036] In this embodiment, both ends of the tread 2 are provided with fixing members, which are installed on the ladder beam 1, and the tread 2 is detachably connected to the fixing members. Specifically, the fixing member is an L-shaped angle steel 4. One side of the L-shaped angle steel 4 is adapted to be fixedly connected to the ladder beam 1, and the other side of the L-shaped angle steel 4 extends towards another ladder beam 1, and the other side of the L-shaped angle steel 4 is adapted to place the tread 2. With this configuration, using L-shaped angle steel 4 as the fixing member, the material is simple and readily available on the construction site. In the event of missing or damaged fixing members, it is easy to quickly find alternative materials for replacement, which can greatly reduce material and construction costs.

[0037] In this embodiment, an L-shaped hole 5 is provided on the side of the L-shaped angle steel 4 that connects to the ladder beam 1. Connectors 6 are provided at both ends of the tread 2. The diameter of the end of the connector 6 closest to the tread 2 matches the width of the L-shaped hole 5, while the diameter of the other end of the connector 6 is greater than the width of the L-shaped hole 5. This arrangement ensures the connection stability between the L-shaped angle steel 4 and the ladder beam 1 through the connector 6. Simultaneously, the larger diameter of the other end of the connector 6 allows for limiting the connection and prevents the tread 2 from loosening during use, thus ensuring the stability of the tread 2 during operation.

[0038] Specifically, the L-shaped angle steel 4 has two L-shaped holes 5, and each end of the pedal 2 has two connecting pieces 6. The two connecting pieces 6 at the same end correspond one-to-one with the two L-shaped holes 5 on the same L-shaped angle steel 4. This arrangement, by setting corresponding L-shaped angle steels 4 and L-shaped holes 5, ensures the stability of the connection between the L-shaped angle steel 4 and the pedal 2, preventing loosening and rotation during use.

[0039] Specifically, connector 6 is a connecting bolt. This design, using a connecting bolt as connector 6, allows for pre-planning of gaps in the connecting bolt before installation, enabling the pedal 2 to be directly installed onto the fixing component by snapping in the connecting bolt, making installation faster and more convenient. Alternatively, after connecting the pedal 2 to the L-shaped angle steel 4, tightening the connecting bolt can make the connection between the pedal 2 and the L-shaped angle steel 4 tighter, greatly improving the connection strength.

[0040] In this embodiment, the ladder beam 1 is made of square steel, and the fastener is welded and fixed to the square steel. This arrangement, using square steel as the ladder beam 1, leverages the readily available material on the construction site. Furthermore, in the event of a missing or damaged ladder beam 1, it is easy to quickly find a replacement material, significantly reducing material and construction costs.

[0041] In this embodiment, hooks 3 are welded and fixed to both ends of the sidewalls of the ladder beam 1, and each hook 3 is provided with a fastening structure 7. This arrangement can prevent the hook-and-loop steel ladder from accidentally coming loose during use, and can ensure the safety of the hook-and-loop steel ladder during use.

[0042] In an alternative embodiment, a telescopic sleeve is fitted onto at least one end of the ladder beam 1. The telescopic sleeve has a fixing member and a tread 2 detachably connected to the fixing member on its side wall. Multiple spaced-apart insertion holes are provided on the ladder beam 1 and the telescopic sleeve. Locking members are provided on corresponding insertion holes on the ladder beam 1 and the telescopic sleeve. The hook 3 is welded and fixed to the telescopic sleeve. This configuration maintains the connection stability between the ladder beam 1 and the telescopic sleeve by providing locking members on the insertion holes. Simultaneously, the telescopic sleeve facilitates extending the length of the ladder beam 1, allowing the hook-and-loop steel ladder to adapt to scaffolding of greater height. Specifically, the spacing between the multiple connection holes is the same.

[0043] In summary, this hook-and-loop steel ladder for scaffolding allows for easy installation by detaching the ladder beams 1 and treads 2. Users simply attach the two ladder beams 1 to the scaffolding using hooks 3, and then attach the treads 2 to the two ladder beams 1. This eliminates the need to transport the heavy and bulky ladder as a whole, and avoids limitations imposed by the construction site area. Even in small construction sites, this detachable hook-and-loop steel ladder can be easily and quickly brought to the site. It is also extremely convenient to move and disassemble when needed. In smaller areas, the ladder can be disassembled and reinstalled, preventing disruption to construction progress caused by moving the ladder.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
