Description

Technical Field

[0001] This invention relates to the field of building security netting technology, and in particular to a cross-shaped positioning buckle used in conjunction with a single, quickly detachable invisible security netting, as well as the installation and disassembly process of the buckle. Background Technology

[0002] The invisible protective netting on building exterior walls consists of multiple independent steel wire ropes arranged in a crisscross pattern. The intersections of these wire ropes need to be fixed and restrained to prevent slippage and wear, ensuring a flat surface. Currently, the mainstream product on the market is an integrated open stainless steel cross-shaped clip. This clip can be fastened to the intersections of the wire ropes after the protective netting is tensioned and shaped. However, this structure is an open clamp-type structure, requiring the use of special crimping pliers to squeeze the clip's wings, relying on the plastic deformation of the metal to tighten the steel wire ropes for fixation.

[0003] Existing cross-shaped clamps have several drawbacks: First, installation requires specialized crimping tools, necessitating the use of pliers for high-altitude operations, making single-person operation inconvenient and reducing construction efficiency; Second, the clamps undergo permanent plastic deformation under pressure, locking the structure and lacking an openable mechanism, requiring the clamps to be cut for destructive removal during later maintenance and replacement of the wire ropes; Third, once damaged, the clamps are rendered unusable, becoming disposable consumables with high maintenance costs; Fourth, manual crimping force cannot be precisely controlled, easily leading to clamp loosening or damage to the wire ropes. The direct contact between the two wire ropes, subjected to repeated swaying and friction under wind loads over time, greatly increases the risk of wire breakage and safety hazards. Summary of the Invention

[0004] Purpose of the invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a rear-mounted invisible protective net cross positioning buckle with a pressing contact protrusion. This overcomes the defects of existing cross buckles, which require special crimping tools, cannot be disassembled without damage, and can only be used once. No special tools are required; installation and disassembly can be completed by hand. The buckle can be disassembled and reassembled without damage and can be reused repeatedly. At the same time, it separates the crossed steel wire ropes to prevent the steel wires from wearing each other.

[0006] Technical solution

[0007] A rear-mounted invisible protective net cross positioning buckle with a clamping contact protrusion includes a cross buckle body and a circular buckle cover. The cross buckle body is a one-piece stainless steel cross structure with through clearance channels in four directions. Inside the cross buckle body, there are through deep grooves and through shallow grooves arranged in a cross-shaped pattern. The through deep grooves and through shallow grooves are perpendicular to each other and have different depths, each accommodating two sets of intersecting steel wire ropes. Four protruding nail feet are distributed at the ends of the cross buckle body. The circular buckle cover is a rigid engineering plastic disc structure with through holes on the disc surface corresponding to the four protruding nail feet. A clamping contact protrusion extends downward from the lower surface of the buckle cover and is embedded in the through deep groove, pressing and limiting the steel wire rope within the deep groove. By pressing the circular buckle cover, the four protruding nail feet pass through the through holes to form an interference fit. The clamping contact protrusion presses the steel wire rope, and the four-point locking structure makes the buckle cover firmly installed and not easy to loosen.

[0008] This buckle is an external, rear-mounted structure that can be fastened and installed at the cross-shaped nodes of the steel wire ropes after the protective net has been stretched and formed.

[0009] Preferably, the cross buckle body is made of 304 stainless steel through one-piece stamping; the round buckle cover is made of UV-resistant PC hard engineering plastic.

[0010] Preferably, the circular buckle cover and the cross buckle body are fixed by only four nail feet and through holes through interference fit, without bolt fasteners and without special tools.

[0011] The present invention also provides a method for installing a cross-shaped positioning buckle, comprising the following steps:

[0012] S1. Assembly and tensioning process: Install all the independent steel wire ropes of the protective net onto the frame, tension the steel wire ropes to the designed pre-tension force, and complete the shaping of the entire protective net.

[0013] S2. Alignment and fastening process: Place the cross buckle body from the outside of the protective net at the cross intersection of the steel wire ropes, so that one set of steel wire ropes is embedded in the deep groove and the other set of steel wire ropes is embedded in the shallow groove.

[0014] S3. Locking and fixing process: Align the round buckle with the four protruding nails and press down. The four nails are inserted into the through holes to complete the interference lock. The pressing contact protrusion on the bottom of the buckle is embedded in the through deep groove to press the internal steel wire rope.

[0015] S4. Disassembly procedure: Use a flat-bladed tool to pry the edge of the round buckle cover to separate the round buckle cover from the protruding nail feet, and completely remove the cross buckle body. The buckle components have no plastic deformation and can be reused.

[0016] Beneficial effects

[0017] 1. The structure of this invention is a post-installation design, which can be added after the entire protective net is tensioned and shaped, which is consistent with the construction time of existing buckles; no special tools such as crimping pliers are required, and the locking installation can be completed by hand pressing. No tools are needed for high-altitude operations, which greatly improves the efficiency of on-site construction.

[0018] 2. Set up through deep grooves and through shallow grooves of different depths. The horizontal and vertical steel wire ropes are arranged independently in separate grooves and separated from each other to avoid direct contact and friction of steel wires at intersections, and eliminate the risk of wire breakage caused by long-term swinging. The bottom surface of the plastic buckle cover is set with a pressing protrusion, which is embedded in the deep groove to flexibly press the steel wire rope, with strong limiting stability and no squeezing or damage to the steel cable.

[0019] 3. The four sets of symmetrically arranged nail feet are used for alignment and locking. Compared with the two-point locking structure, the force is more even and the cover is less likely to shift, lift, or fall off. The entire set of clips can be separated without damage by prying the plastic cover. The body and the cover will not undergo plastic deformation. After disassembly, it can be reused completely, eliminating the disadvantage of the existing products being scrapped at one time and greatly reducing the later maintenance costs.

[0020] 4. The installation method is simple and requires no special tools. Adding the clips does not affect the original function of independently disassembling and replacing a single wire rope. Detailed Implementation

[0028] Example 1: Snap-fit ​​structure

[0029] The cross buckle body is made of 304 stainless steel and is stamped in one piece. The cross has four-way clearance channels and a cross-shaped through deep groove and through shallow groove inside. Four symmetrical protruding nail feet are set at the four corners of the end face. The plastic buckle cover has four corresponding through holes. The lower surface is integrally formed to abut against the protrusion. After buckling, the protrusion presses into the deep groove to tighten the steel wire rope.

[0030] Example 2: Installation Method

[0031] The first step is to tension all the steel wire ropes of the protective net to the set preload to complete the overall shaping;

[0032] The second step is to fasten the cross buckle body to the intersection of the steel wire ropes and place the horizontal and vertical steel wire ropes in the grooves.

[0033] Third step, align the four nail feet and press the plastic buckle cap to press the protrusion against the steel wire in the deep groove to complete the fixation;

[0034] During maintenance, pry open the plastic cover and remove the clip completely to replace the wire rope individually. The clip can be reused.
