Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to an installation structure for an anti-fall support for attached lifting scaffolding. Background Technology

[0002] Traditional fall arrestors for attached scaffolding are typically fixed to the edge beams or shear walls of concrete structures via pre-embedding or perforation. However, in steel frame structures, edge beams are often made of H-beams, floor slabs are relatively thin (100-120mm), and column spacing is large (>8m), making traditional pre-embedding or perforation methods insufficient to meet structural load-bearing and space requirements. Current technologies often employ temporary supports or reinforcement measures to address these issues, but these suffer from low construction efficiency, high costs, and safety hazards.

[0003] The publicly available similar technical solutions mainly rely on the direct fixing of the structural edge beams, without proposing an effective load transfer path design for the characteristics of the steel frame, which leads to difficulties in installing the fall arrestor or failure to meet the mechanical balance requirements of force transmission. Utility Model Content

[0004] The purpose of this utility model is to provide an installation structure for an anti-fall support for attached lifting scaffolding, in order to solve the technical problems that traditional anti-fall supports cannot be reliably installed on thin floor slabs and large column spacing in steel frame structures, and that the force transmission path is unclear, which can easily lead to structural damage.

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

[0006] An anti-fall support installation structure for attached lifting scaffolding includes a floor slab and a support installation structure. The support installation structure is installed on at least two floor slabs. The support installation structure includes an attachment rod and an anchor ring. The attachment rod is placed on the floor slab near the edge and is perpendicular to the edge of the floor slab. A through hole is provided on the floor slab near the end of the attachment rod. There are two through holes, one on each side of the attachment rod. The anchor ring is U-shaped, and its upper end passes through the through hole. A pressure plate is provided at the top of the attachment rod, and the upper end of the anchor ring passes through the pressure plate and is fixed by a nut. A hole is provided on the floor slab at the front side corresponding to the attachment rod. A pull ring is provided at the bottom of the attachment rod at the corresponding hole. A lifting ring is provided at the top of the attachment rod near the front end. A tie rod is provided between the pull ring at the bottom of the upper attachment rod and the lifting ring at the top of the lower attachment rod.

[0007] Preferably, an elastic gasket is added to the contact surface between the attachment rod and the floor slab.

[0008] Preferably, a tension sensor is provided at the end of the pull rod.

[0009] Preferably, the tie rod includes a standard section and an adjusting section, and the standard sections are connected to each other or to the adjusting section by a flange or high-strength bolts.

[0010] Preferably, the upper end of the pull rod is provided with a through hole, and the pull ring passes through the through hole and is connected to the pull rod; the lower end of the pull rod is provided with a U-shaped hook, and the U-shaped hook is hinged to the lifting ring.

[0011] Preferably, a stress diffusion pad is added between the pressure plate and the attachment rod; the stress diffusion pad is frustum-shaped and has radial grooves at its bottom.

[0012] Compared with the prior art, the present invention has the following features and beneficial effects.

[0013] 1. This utility model utilizes the technology of cantilevered anchoring to transfer the relevant loads of the attached lifting scaffold to the main structure through the attachment rod, solving the difficulty of installing anti-fall supports for attached lifting scaffolds in steel frame structures in the traditional way. The self-weight, wind load, and construction load of the attached lifting scaffold are transferred to the attachment rod through the anti-fall support. According to the principle of moment balance, the force on the attachment rod is applied to the main structure through the tie rod and the tail anchor ring. Ultimately, the main structure bears the relevant loads of the attached lifting scaffold, resulting in a reasonable stress distribution.

[0014] 2. This utility model uses a stress diffusion pad 11 with a frustum shape to diffuse concentrated stress from the contact point of the pressure plate to the bearing surface of the attachment rod, thereby avoiding stress on the attachment rod and effectively reducing the stress on the contact surface. The radial grooves guide stress transmission along a 30°~60° direction, preventing stress wave superposition. Simultaneously, the plastic deformation of the frustum can effectively absorb impact energy. Attached Figure Description
