Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an attachment connection component and a construction ladder having the attachment connection component. Background Technology

[0002] Safety cages are safety facilities used in the construction industry for vertical personnel passage and material transfer. In related technologies, the cage is typically fixedly connected to the building, relying on pre-embedded components installed during the main building construction phase to connect with attached circular pipe fittings on the cage frame. However, due to factors such as concrete pouring deviations, positioning accuracy errors of pre-embedded components, and fluctuations in construction floor elevation, the pre-embedded components and the attached circular pipe fittings of the cage often fail to be on the same horizontal plane during installation.

[0025] Safety cages are safety facilities used in the construction industry for vertical personnel passage and material transfer. In related technologies, the cage is typically fixedly connected to the building, relying on pre-embedded components installed during the main building construction phase to connect with attached circular pipe fittings on the cage frame. However, due to factors such as concrete pouring deviations, positioning accuracy errors of pre-embedded components, and fluctuations in construction floor elevation, the pre-embedded components and the attached circular pipe fittings of the cage often fail to be on the same horizontal plane during installation. This necessitates secondary chiseling, welding, or re-embedding operations, increasing construction costs and significantly delaying the project schedule. Furthermore, in some special cases, it is impossible to directly drill holes in the cage and connect it with bolts, making installation and fixation between the cage and the building difficult, resulting in substandard stability and failure to meet safety regulations.

[0026] Therefore, such as Figures 1 to 4 As shown, the attachment connection component proposed in this utility model includes: a first fixing member 100, a second fixing member 200, and a connector 400. The first fixing member 100 and the second fixing member 200 together enclose a pipe fitting enclosing space 300. The first fixing member 100 and the second fixing member 200 are detachably connected to the ladder cage 600. The pipe fitting enclosing space 300 formed by the first fixing member 100 and the second fixing member 200 can be freely positioned along the axial direction of the pipe fitting in the ladder cage 600, and then locked by a detachable connection. This allows for immediate adjustment of height and angle on the installation site, directly compensating for elevation or positional errors of the pre-embedded parts 810 in the building 800, without the need for secondary chiseling, welding, or re-embedding.

[0027] Furthermore, the connector 400 is fixedly connected to the first fixing member 100. The connector 400 can be fixedly connected to the first fixing member 100 by welding, fastener connection, or adhesive bonding, or the connector 400 can be integrally formed with the first fixing member 100. The connector 400 is used for fixed connection with the building 800. When the connector 400 is connected to the embedded part 810, it is not necessary to drill additional holes in the ladder cage 600 or the building 800, avoiding cracking of thin-walled components, ensuring reliable fixation between the ladder cage 600 and the building 800, and meeting safety specifications.

[0028] In other embodiments of this utility model, the connector 400 is fixedly connected to the second fixing member 200. The connector 400 can be fixedly connected to the second fixing member 100 by welding, fastener connection, or adhesive bonding, or the connector 400 can be integrally formed with the second fixing member 100. The connector 400 is used for fixed connection with the building 800. When the connector 400 is connected to the embedded part 810, it is not necessary to drill additional holes in the ladder cage 600 or the building 800, avoiding cracking of thin-walled components, ensuring reliable fixation between the ladder cage 600 and the building 800, and meeting safety standards.

[0029] In some embodiments of the present utility model, as Figures 1 to 3 shown, the first fixing member 100 is provided with a plurality of first connecting holes 110, the second fixing member 200 is provided with a plurality of second connecting holes 210, the first connecting holes 110 and the second connecting holes 210 correspond one by one, and the diameter of the first connecting holes 110 is equal to the diameter of the second connecting holes 210. The first fixing member 100 and the second fixing member 200 are fixed by fasteners located in the first connecting holes 110 and the second connecting holes 210. The multi-point bolt connection disperses the clamping stress, avoids local deformation of the round tube caused by single-point force, and enhances the overall connection strength and stability.

[0030] In some embodiments of the present utility model, as Figures 1 to 3 shown, the cross-sectional shape of the first fixing member 100 is "U" shaped, including two opposite support portions, and a connecting portion connecting the two support portions and perpendicular to the two support portions. The shape of the second fixing member 200 refers to that of the first fixing member 100, which will not be elaborated here. There are four first connecting holes 110, and the four first connecting holes 110 are divided into two groups, with two in each group. The two groups of first connecting holes 110 are symmetrically arranged along the center line of the first fixing member 100, that is, the two groups of first connecting holes 110 are respectively arranged on the two support portions. There are four second connecting holes 210, and the four second connecting holes 210 are divided into two groups, with two in each group. The two groups of second connecting holes 210 are symmetrically arranged along the center of the second fixing member 200. The multi-point bolt connection disperses the clamping stress, avoids local deformation of the round tube caused by single-point force, and enhances the overall connection strength and stability.

[0031] In some embodiments of the present utility model, as Figures 1 to 3 shown, the first fixing member 100 is provided with a first half groove 120, the second fixing member 200 is provided with a second half groove 220. The rectangular cross-section of the first half groove 120 is the same in shape and size as that of the second half groove 220, and they are symmetrically distributed on both sides of the center line of the pipe accommodating space. The first half groove 120 and the second half groove 220 jointly enclose a rectangular clamping groove. The groove walls of the first half groove 120 and the second half groove 220 are evenly fitted with the four sides of the rectangular pipe fitting of the ladder cage 600, increasing the contact area, making the force uniform, and preventing slippage. The rectangular cross-section can prevent the first fixing member 100 and the second fixing member 200 from rotating relative to the pipe fitting, ensuring that the connecting member 400 and the embedded part 810 of the building 800 always maintain the correct orientation, and improving the overall installation accuracy and stability.

[0032] In some embodiments of the present utility model, as Figure 4As shown, the first fixing member 100 is provided with a first semi-groove 120, and the second fixing member 200 is provided with a second semi-groove 220. The rectangular cross-section of the first semi-groove 120 and the rectangular cross-section of the second semi-groove 220 have the same shape and size, and are symmetrically distributed on both sides of the centerline of the pipe accommodating space. Both the first semi-groove 120 and the second semi-groove 220 are provided with arc-shaped surfaces, and the first semi-groove 120 and the second semi-groove 220 together form an annular clamping groove. The groove surfaces of the first semi-groove 120 and the second semi-groove 220 form a full circumferential fit with the outer wall of the ladder cage 600 circular pipe, maximizing the contact area, distributing the force evenly, and enhancing the anti-slip and anti-torsion performance. The symmetrical structure ensures the force balance after clamping, avoids local stress concentration, and improves the connection reliability and service life.

[0033] In some embodiments of this utility model, such as Figure 4 As shown, both the first half-groove 120 and the second half-groove 220 have an elastic layer 500 on their walls. The elastic layer 500 is made of elastic rubber and can be compressed and deformed to adapt to pipe fittings of different cross-sectional sizes. During the clamping process, the elastic layer 500 can be compressed and deformed to automatically fill the gaps between the first half-groove 120, the second half-groove 220 and pipe fittings of different diameters, enabling the same attachment connection component to adapt to pipe fittings of various cross-sectional sizes. The elastic layer 500 can eliminate hard contact gaps, avoid local stress concentration caused by point contact or line contact, improve clamping force and anti-slip performance, and reduce vibration noise.

[0034] In some embodiments of this utility model, such as Figure 2 As shown, the outer wall of the connector 400 is provided with two reinforcing ribs 410. The reinforcing ribs 410 have a triangular structure and can be integrally formed with the connector 400. The two reinforcing ribs 410 are symmetrically arranged along the axial direction of the connector 400. The two reinforcing ribs 410 extending along the axial direction of the connector 400 directly improve the bending and torsional stiffness of the connector 400, reducing deformation when subjected to the load of the cage 600 and wind load. The symmetrical structure ensures that the force is evenly transmitted to the first fixing member 100 and the second fixing member 200, avoiding stress concentration at single points and ensuring long-term reliable fixation between the connector 400 and the embedded part 810 of the building 800. It should be noted that the connector 400 can be a round tube, a square tube, or a tube with a triangular cross-section; the connector 400 can be flexibly changed according to actual usage requirements.

[0035] In some embodiments of this utility model, such as Figure 1As shown, connector 400 is a round or square tube, and its length is A, where 200mm ≤ A ≤ 500mm. A connector 400 with a length in the range of 200mm to 500mm ensures sufficient overlap length with the embedded part 810 of the building 800 to meet load-bearing requirements, while avoiding excessive length that would increase cantilever bending moment. This adapts to different construction spacings and meets diverse scenario needs. Connector 400 can also be 300mm long. A 300mm long connector 400 balances sufficient overlap length with a smaller cantilever bending moment, ensuring the connection stability between connector 400 and embedded part 810.

[0036] In some embodiments of this utility model, such as Figure 1 As shown, the first fixing member 100 and the second fixing member 200 have the same thickness. The thickness of the first fixing member 100 is B, where 3mm ≤ B ≤ 10mm. A first fixing member 100 with a thickness of 3mm to 10mm ensures sufficient structural strength to withstand the pressure from personnel and material loads during ladder use, preventing deformation or breakage. It also avoids increased weight and installation inconvenience due to excessive thickness, balancing strength and practicality. Alternatively, the first fixing member 100 can be 5mm thick. A 5mm thick first fixing member 100 and second fixing member 200 ensure both clamping strength and lightweight design, reducing material usage and additional load on the ladder cage 600, facilitating on-site handling and installation.

[0037] The construction ladder according to an embodiment of the present invention includes an attachment connection component according to an embodiment of the present invention.

[0038] According to the embodiments of the present invention, the construction ladder, through the use of the attachment connection components of the present invention, allows the first fixing member 100 and the second fixing member 200 to form a rectangular or annular enclosing groove. The detachable connection allows for adjustable height and connection with the embedded part 810, and is adaptable to pipe fittings of different cross-sections. The elastic layer 500 of the groove wall can be compressed and deformed, further ensuring compatibility with pipe fittings of different sizes, eliminating the need for frequent replacement of parts and improving the ladder's versatility. The first connecting hole 110 and the second connecting hole 210 are symmetrically arranged and fixed with fasteners, enhancing the stability of the fixing connection, improving its load-bearing and deformation resistance, and making the connection between the construction ladder and the building 800 more secure. Simultaneously, no additional drilling is required, avoiding structural damage, ensuring the safety of the construction ladder, simplifying installation, and facilitating efficient construction.

[0039] Reference Figures 5 to 7In this embodiment of the invention, the construction ladder includes a ladder cage 600 and support pipes 610 arranged around the perimeter of the ladder cage 600. The support pipes 610 are distributed around the ladder cage 600, forming a stable support. Connectors 400 face the building 800. Embedded parts 810 are connected to connectors 400 via connecting rods 700, and the connecting rods 700 are fixedly connected to connectors 400 via universal joints 710. Attachment connection components are connected to both sides of the ladder cage 600, allowing the ladder cage 600 to be fixedly connected to the embedded parts 810 of the building 800 via these attachment connection components. The connection height between the ladder cage 600 and the embedded parts 810 can be adjusted using the attachment connection components, quickly adapting to the height of the embedded parts 810 without secondary processing or welding, achieving a reliable connection between the ladder cage 600 and the building 800, improving installation efficiency and overall stability.

[0040] Reference Figure 8 In another embodiment of this utility model, the connector 400 can also be arranged facing away from the ladder cage 600. Attachment connection components are connected to both the left and right sides of the ladder cage 600. A pipe fitting space 300 is formed between the first fixing member 100 and the second fixing member 200, thereby fixing the connection to the support pipes 610 on the left and right sides of the ladder cage 600. The embedded part 810 is connected to the connector 400 via a connecting rod 700. The ladder cage 600 can be fixedly connected to the embedded part 810 of the building 800 through the attachment connection components on both sides, thereby quickly adapting to the height of the embedded part 810 without secondary processing or welding, achieving a reliable connection between the ladder cage 600 and the building 800, improving installation efficiency and overall stability.
