Description

Technical Field

[0001] The utility model belongs to the field of attached lifting scaffolds, and in particular relates to an integral attachment device of the attached lifting scaffold. Background Art

[0002] As a new type of scaffolding system, attached lifting scaffolding has gained widespread application in modern construction due to its efficiency, convenience, and cost-effectiveness. It can gradually rise and fall as the building structure progresses, providing construction workers with a stable and reliable working platform, significantly improving construction efficiency and safety. In the construction of high-rise and super-high-rise buildings, attached lifting scaffolding plays an irreplaceable role, effectively solving the problems of traditional scaffolding, such as the difficulty of erection, long construction periods, and high costs.

[0003] There are odd and even floors in the building structure, such as Figure 1 As shown, structure 7 is a first building structure, and the two upper layers are a second building structure 8 that contracts inwards. Since the second building structure 8 lacks support, it is impossible to install attachment supports on each layer in the vertical direction, resulting in a safety hazard to the scaffolding frame. Utility Model Content

[0004] An object of the present invention is to solve at least the above problems and to provide at least the advantages to be described below.

[0005] The utility model provides the following technical solution: an integral attachment device for an attached lifting scaffold, comprising a supporting column and a frame structure; the supporting column is located between two upper and lower first building structures and is connected to a second building structure between the two upper and lower first building structures; the second building structure is retracted inwardly relative to the first building structure;

[0006] The bottom of the supporting column is fixed to the top surface of the first building structure of the lower layer, and the top of the supporting column is connected to the first building structure of the upper layer through an adjustable pull rod; an adjustable support rod is connected between the supporting column and the first building structure of the lower layer, and a horizontal support is connected between the supporting column and the second building structure. A scaffolding attachment device is installed on the supporting column at the horizontal support position, the scaffolding attachment device on the supporting column is aligned with the scaffolding attachment device on the first building structure, and the frame structure is connected to the scaffolding attachment device.

[0007] Furthermore, two adjustable support rods with diagonal braces are connected between the support column and the first building structure of the lower layer, and the two adjustable support rods are symmetrically arranged on both sides of the support column; the top end of the adjustable support rod is located at the connection node between the support column and the horizontal support, and the line connecting the bottom ends of the two adjustable support rods and the bottom end of the support column is a triangle.

[0008] Furthermore, the supporting column includes a plurality of standard sections, and the standard sections are connected to each other by bolts.

[0009] Furthermore, the horizontal support is connected to the second building structure via through-wall bolts.

[0010] Furthermore, the adjustable pull rod is inclined toward the interior of the first building structure on the upper floor.

[0011] Furthermore, the standard section of the supporting column includes two back-facing channel steels, a rib plate is welded between the two back-facing channel steels, and a connecting plate is welded to the top and bottom ends of the two back-facing channel steels.

[0012] Furthermore, the scaffold attachment device is fixed to the supporting column by means of bolts and clamping plates.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] 1. Through innovative support and rigid tie rod design, we successfully remodeled the node areas where the odd-even layer attachment device could not attach. This ensures that the attached lifting scaffold can be firmly attached to the main building structure even in complex and changing building structures, greatly reducing the attachment instability caused by the special structure and fundamentally reducing the possibility of safety hazards in the scaffolding frame.

[0015] 2. The combined structure of the support and the hard pull rod not only realizes the effective installation of the attachment device, but also enhances the overall structural stability of the scaffolding. When facing wind loads, earthquake loads and various dynamic loads during the construction process, it can better disperse and transfer the load, make the scaffolding frame more evenly stressed, and reduce the local stress concentration phenomenon. Compared with traditional treatment methods, the technical solution of the utility model can significantly improve the scaffolding's anti-deformation and anti-overturning capabilities under complex working conditions, effectively prevent the scaffolding from shaking, tilting and other unstable conditions during use, provide a more stable working environment for the construction process, and further improve the safety of the construction site.

[0016] 3. Unlike traditional methods that require drilling holes in the building structure, inserting rebar, or constructing extensive auxiliary structures, the technical solution of this utility model minimizes damage to and modification of the main building structure. This not only reduces construction difficulty and risk, but also avoids construction delays and additional costs caused by large-scale structural modifications. Construction workers can quickly complete the installation and commissioning of the attached lifting scaffolding without compromising the integrity and stability of the building structure, making the construction process smoother and improving overall construction efficiency.

[0017] 4. The integrated attachment device of the attached lifting scaffold of this utility model utilizes a relatively simple support and rigid tie rod structure, primarily made of common steel and other building materials, resulting in a relatively low cost. This significantly reduces material procurement costs compared to traditional methods that require the use of large quantities of specialized steel for auxiliary structures or specialized attachment supports. Furthermore, due to its simple structure and high material utilization, it further conserves material resources, meeting the requirements of modern construction for cost control and resource conservation, and bringing significant economic benefits to construction companies.

[0018] 5. Regardless of the complexity and diversity of the building structure's odd and even story variations, the integrated attachment device of this utility model's attached lifting scaffold can effectively adapt to these structural variations by rationally adjusting parameters such as the position, angle, and length of the supports and rigid tie rods. Whether it's differences in floor heights, changes in wall structure, or unique beam and column layouts, these can all be flexibly addressed with this utility model, ensuring the secure attachment and proper operation of the scaffold.

DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0024] like Figure 1 、 Figure 3As shown: An integral attachment device of an attached lifting scaffold includes a support column 2 and a frame structure 6; the support column 2 is located between the upper and lower first building structures 7 and is connected to the second building structure 8 between the upper and lower first building structures 7; the second building structure 8 is retracted inward relative to the first building structure 7; the first building structure 7 is a horizontal cantilever structure; the second building structure 8 is a balcony structure.

[0025] The bottom of the supporting column 2 is fixed to the top surface of the first building structure 7 of the lower layer, and the top of the supporting column 2 is connected to the first building structure 7 of the upper layer through an adjustable pull rod 4; an adjustable support rod 1 is connected between the supporting column 2 and the first building structure 7 of the lower layer, and a horizontal support 3 is connected between the supporting column 2 and the second building structure 8. A scaffolding attachment device 5 is installed on the supporting column 2 at the position of the horizontal support 3. The scaffolding attachment device 5 on the supporting column 2 is aligned with the scaffolding attachment device 5 on the first building structure 7, and the frame structure 6 is connected to the scaffolding attachment device 5.

[0026] The weight of the scaffolding frame structure 6 and its associated loads are transferred via the scaffolding attachment device 5 to the first and second building structures 7 and 8. After installation, the scaffolding frame is subject to horizontal forces inward, as well as horizontal wind pressure. Therefore, horizontal supports 3 are required to resist these horizontal loads. Adjustable tie rods 4 are angled toward the interior of the upper first building structure 7. They primarily bear vertical tension, sharing the vertical load with the support columns 2.

[0027] Two adjustable support rods 1 with diagonal braces are connected between the support column 2 and the first building structure 7 of the lower layer. The two adjustable support rods 1 are symmetrically arranged on both sides of the support column 2, which can ensure the stability of the overall structure and prevent the lateral force from causing the overall structure to become unstable and dangerous; the top end of the adjustable support rod 1 is located at the connection node between the support column 2 and the horizontal support 3, and the line connecting the bottom ends of the two adjustable support rods 1 and the bottom end of the support column 2 is a triangle.

[0028] The design of the adjustable tie rods 4 and adjustable support rods 1 emphasizes their strength and rigidity to withstand the tensile and compressive forces imparted by the scaffolding. They can be constructed from high-strength steel, with their cross-sectional shape and dimensions precisely calculated to meet mechanical performance requirements. This structure effectively transfers the load from the scaffolding to the building structure, allowing them to coordinate and share the load during the load-bearing process, avoiding excessive or uneven localized forces.

[0029] The adjustable support rod 1 comprises two rigid steel pipes which are slidably connected and have holes evenly arranged on the two rigid steel pipes. The length of the two rigid steel pipes can be adjusted by bolts. The structure of the adjustable pull rod 4 is the same as that of the adjustable support rod 1.

[0030] The horizontal support 3 is formed by welding two channel steels in reverse, and is customized according to the distance between the floor and the frame. The horizontal support 3 is connected to the second building structure 8 by through-wall bolts.

[0031] The support column 2 consists of several standard sections connected by bolts. The attachment device can be effectively installed to accommodate varying floor heights, building shapes (such as circular and polygonal), and wall materials (such as concrete, masonry, and steel) by properly adjusting the parameters of the support column 2, adjustable tie rod 4, and adjustable support rod 1.

[0032] like Figure 2 As shown, the standard section of the support column 2 includes two oppositely facing channel steels 2.1, a rib plate 2.2 welded between the two oppositely facing channel steels 2.1, and connecting plates 2.3 welded to the top and bottom ends of the two oppositely facing channel steels 2.1. The scaffolding attachment device 5 is clamped to the support column 2 using bolts and clamping plates 5.1.

[0033] The technical solution of the utility model can effectively improve the safety of the scaffolding, reduce the probability of construction accidents, and protect the lives of construction workers; by optimizing the construction process and reducing costs, the quality and efficiency of construction are improved, providing a guarantee for the smooth progress of construction projects; at the same time, it reduces the damage and impact on the building structure, and meets the requirements of sustainable development of buildings.

[0034] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
