Description

Technical Field

[0001] This utility model relates to the field of scaffolding installation technology, and in particular to a connecting fastener for scaffolding pipes and steel grating platforms. Background Technology

[0002] Scaffolding refers to various supporting structures erected on construction sites to facilitate worker operations and vertical and horizontal transportation. With the development of the construction industry, scaffolding is increasingly widely used in industrial construction, enabling workers to work in different locations and providing external protective frames for workers at heights, ensuring their safety during high-altitude operations. Simultaneously, various types of ground-supported scaffolding are extensively used in steel structure installation for material handling, storage, support, and other load-bearing purposes, including material receiving platforms, formwork support frames, and installation support frames, playing a crucial role in construction.

[0003] Scaffolding couplers generally refer to intermediate connecting parts that connect two structural members. In construction engineering, they are mostly used to fix steel pipe scaffolding with an outer diameter of Φ48mm. Currently, there is no mature solution for connecting scaffolding pipes to steel grating platforms. Ground-supported scaffolding erected on steel structures not only requires interconnection between scaffolding pipes, but also often needs to be supported on steel beams or steel grating platforms in steel structure workshops. Because steel structures are usually permanent components, they have high requirements for paint corrosion protection and structural impact resistance. When scaffolding pipes are directly placed on the ground, they can damage the structure. Protective measures are needed when supporting scaffolding pipes. Vertical pipe length control is mostly based on human perception, which cannot evenly distribute load. Existing scaffolding often uses steel pads directly placed on the steel platform. When the platform is small or has irregular edges, the steel pads are not suitable for fixing, lacking reliable connections. Existing steel pads can only transmit vertical loads, and there is a risk of slippage when the structure vibrates. The pads can also penetrate the steel platform, posing a risk of falling objects from height, thus creating certain safety hazards for the use of scaffolding. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a connecting fastener for scaffolding pipes and steel grating platforms. By using a designed T-shaped base with lifting clamps, it can prevent damage to the steel grating platform caused by the scaffolding pipes falling directly onto it. At the same time, by using a designed tubular base with locking fasteners, it can avoid the safety risks of falling objects from height caused by the direct use of steel plate supports.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0035] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0036] Example 1

[0037] This embodiment provides a connecting fastener 100 for scaffolding pipes and steel grating platforms, such as... Figure 1 and 2 As shown, the connecting fastener 100 includes a T-shaped base 2 placed on the steel grating platform 300, such as... Figure 1 As shown, the T-shaped base 2 is divided into left and right sides. One side of the T-shaped base 2 is connected to a lifting clamp 1 via a first bolt 11. The other side of the T-shaped base 2 is connected to a tubular base 3 via a rotating pin 9. A locking fastener 4 is connected to one end of the tubular base 3, and an adjusting shaft 5 is connected to the other end. The end of the locking fastener 4 near the adjusting shaft 5 has a groove structure, and the adjusting shaft 5 slides and clamps within the groove structure. The tubular base 3, in conjunction with the locking fastener 4, is fixed using the adjusting shaft 5 to clamp and secure the scaffolding tube 200.

[0038] Specifically: such as Figure 5As shown in the T-shaped base structure diagram, the T-shaped base 2 includes a base plate 202 and a fastener mounting plate 201 welded perpendicularly to it. The base plate 202 is placed on the steel grating platform 300. The fastener mounting plate 201 divides the base plate 202 into two sides. A first connecting hole 203 is provided on one side of the base plate 202. A first bolt 11 passes through the first connecting hole 203 to connect the lifting clamp 1, fixing the steel grating platform 300 in the middle. Because the first bolt 11 is rotatable and adjustable, it is less constrained by the scaffolding pipe 200. The installation position can be adjusted according to the actual situation of the scaffolding pipe 200 and the steel grating platform 300, and is not limited by the position of the base plate or the shape of the steel grating platform. Therefore, it is particularly suitable for use when the scaffolding pipe is placed on the edge of the platform.

[0039] The other side of the base plate 202 is a planar structure 205, which is used for the ground placement of scaffolding pipes and reliably transmits the vertical load of the scaffolding and its load-bearing platform. The fastener mounting plate 201 has a second connecting hole 204. The rotating pin 9 passes through the second connecting hole 204 and connects to the tubular base 3 on the other side of the base plate, and is constrained and fixed by a designed cotter pin 8.

[0040] like Figure 6 As shown in the structural diagram of the lifting clamp, the lifting clamp 1 can be stamped and formed, with a simple structure, low cost, and standardized production capability. Specifically, in this embodiment, the lifting clamp 1 has an overall channel-shaped structure. The channel-shaped structure can save materials and improve rigidity. The overall width is smaller than the width of the steel grating platform uprights. The upper surface of the lifting clamp 1 has a toothed structure 103, and a bolt connection hole 102 is provided in the middle of the lower surface of the lifting clamp 1. The first bolt 11 passes through the bolt connection hole 102.

[0041] Furthermore, the upper surface of the lifting clamp 1 is not limited to a toothed structure; it can be a corrugated structure or a sawtooth structure.

[0042] like Figure 3 As shown in the diagram of the tubular base structure, the inner side of the tubular base 3 is an arc surface 305. A bottom hole 301 is provided in the middle of the tubular base 3. The rotating pin 9 is connected to the second connecting hole 204 of the T-shaped base through the bottom hole 301. This allows for the installation of ground-mounted scaffolding pipes 200 and can also be used for the connection and fixation of inclined scissor bracing. Both ends of the tubular base 3 have a groove-shaped structure and a side hole 302 that penetrates the groove-shaped structure. A locking member 4 is connected to the side hole at one end of the tubular base through a second bolt 13, and an adjusting shaft 5 is connected to the side hole at the other end of the tubular base through a third bolt 7.

[0043] like Figure 4As shown in the structural diagram of the locking fastener, the inner side of the locking fastener 4 is an arc surface, which is opposite to the inner side of the tubular base 3. The radius of the arc surface 402 on the inner side of the locking fastener 4 is larger than the radius of the scaffolding tube 200 to accommodate different models of scaffolding tubes. One end of the locking fastener 4 has a first through hole 401, and the other end has a locking fastener groove 403. The end of the locking fastener groove 403 has an anti-detachment protrusion 404. Specifically, the end of the locking fastener 4 with the first through hole 401 can be inserted into the groove-shaped structure at one end of the tubular base 3, and the first through hole communicates with the side hole on the groove-shaped structure at one end of the inserted tubular base. The connection between the tubular base 3 and the locking fastener 4 is achieved with the help of the second bolt 13.

[0044] like Figure 7 As shown in the structural diagram of the adjusting shaft, the end of the adjusting shaft 5 is a sleeve structure, and the shaft part 502 is a screw structure. A second through hole 501 is provided at the end of the adjusting shaft. The end of the adjusting shaft with the second through hole can be inserted into the groove structure at the other end of the tubular base. The second through hole communicates with the side hole on the groove structure at the inserted end of the tubular base. The tubular base and the adjusting shaft are connected by a third bolt. The shaft part of the adjusting shaft 5 is clamped in the locking groove 403. A wing nut 6 is sleeved on the shaft part of the adjusting shaft. Specifically, the wing nut 6 is on the outside of the locking member 4. The wing nut 6 has a locking and anti-loosening function, and the anti-dislodgement protrusion 404 designed at the end of the locking groove 403 can prevent the wing nut 6 from slipping off along the outer plane of the locking member.

[0045] The method of using the connecting fastener between the scaffolding pipe and the steel grating platform provided in this embodiment is as follows: Place the scaffolding pipe steel grating connecting fastener 100 on the steel grating platform 300. After fixing the scaffolding steel pipe 200 using a tubular base and locking fastener, use a lifting clamp to fix the scaffolding pipe steel grating connecting fastener 100 on the steel grating platform 300. This avoids the risk of the base sliding and falling objects from height, and distributes the stress of the scaffolding on the steel grating platform. Since the scaffolding pipe steel grating connecting fastener 100 can rotate arbitrarily along the axis of the scaffolding pipe 200 before fixing, the scaffolding pipe steel grating connecting fastener 100 can be flexibly and conveniently installed in a suitable position on the steel grating platform 300, especially suitable for independent small platforms and irregularly shaped parts. Before use, rotate the lifting clamp 1 to be parallel to the vertical ribs of the steel grating platform and lower it into the gaps between the vertical ribs. Then, rotate the lifting clamp 1 90 degrees to be perpendicular to the vertical ribs and tighten it with the connecting bolt 11 to ensure that the lifting clamp is firmly pressed against the underside of the vertical ribs of the steel grating platform, preventing horizontal movement of the scaffolding steel grating connecting fasteners. First, place the scaffolding pipe 200 against the inner side 305 of the tubular base 3, and then rotate it to fasten the scaffolding pipe 200 from the axis of the third bolt 7. Use the adjusting shaft 5 to lock the other end from the groove 403 and tighten it with the wing nut 6 to prevent loosening.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
