Description

Technical Field

[0001] This utility model relates to the field of edge protection technology, and in particular to a pre-embedded edge opening protection connector. Background Technology

[0002] In building construction, openings are often left in advance where windows are installed; these are called edge openings. Usually, these openings need to be protected to ensure the safety of construction workers.

[0003] Currently, commonly used edge opening protection connectors mainly consist of guardrails and fixing plates. The guardrails are installed in a crisscross pattern above the opening to prevent people from passing through and causing accidents when the opening is open. This method effectively warns of the opening's location. During installation, the number and position of the guardrails must be determined on the wall according to the opening size. Holes are then drilled in the wall surface, and the guardrails are secured using fixing plates. They are removed when windows are installed.

[0004] Therefore, existing protective connectors require drilling during installation, which damages the wall surface and is cumbersome. Removal is also not quick, making construction difficult. Furthermore, when the gaps between the protective bars are too large, their protective effect is compromised. Utility Model Content

The support rod is installed in the fixing groove pre-embedded in the wall in a front and back manner, and a mesh plate is set between the front and back support rods, so as to realize the safe covering of the opening and facilitate the operation of construction personnel.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a pre-embedded edge opening protection connector, including a U-shaped groove pre-embedded in the upper and lower walls around the opening, the opening of the U-shaped groove facing the opening, the number of U-shaped grooves in the upper wall and the U-shaped grooves in the lower wall being equal and their positions being opposite to each other, a first support rod and a second support rod respectively provided in the front-rear direction between the U-shaped grooves in the upper wall and the U-shaped grooves in the lower wall, the first support rod and the second support rod being detachably connected to the bottom of the U-shaped groove, a flexible mesh plate being provided between the first support rod and the second support rod, the flexible mesh plate being connected to the first support rod and the second support rod respectively by fixing ropes passing through its mesh holes, an annular hook being provided on the outer surface of the U-shaped groove facing the opening, and the flexible mesh plate being looped on the annular hook by fixing ropes passing through its mesh holes.

[0007] Furthermore, the side of the U-shaped groove is provided with multiple horizontal limiting rods, which are located inside the wall.

[0008] Furthermore, the multiple limiting rods are symmetrically distributed in the longitudinal direction.

[0009] Furthermore, the first support rod has a first protrusion at its upper and lower ends, and a first recess at the front end of the bottom of the U-shaped groove. The first protrusion matches the first recess. The second support rod has a second protrusion at its upper and lower ends, and a second recess at the rear end of the bottom of the U-shaped groove. The second protrusion matches the second recess.

[0010] Furthermore, a fixing block is provided between the first support rod and the second support rod. The fixing block is detachably connected to the bottom of the U-shaped groove. The fixing block, the first support rod, and the second support rod can fill the U-shaped groove.

[0011] Furthermore, the fixing block has a third protrusion on the side facing the bottom of the U-shaped groove, and a third recess is provided in the middle of the bottom of the U-shaped groove, with the third protrusion matching the third recess.

[0012] Furthermore, the front and rear ends of the fixing block are detachably connected to the first support rod and the second support rod, respectively.

[0014] Furthermore, the upper surface of the opening of the U-shaped groove is detachably connected to two limiting plates, which, when spliced ​​together, can cover the opening of the U-shaped groove.

[0015] Furthermore, the two limiting plates are bolted to the upper surface of the opening of the U-shaped groove.

[0016] This utility model has the following advantages compared with the prior art:

[0017] This utility model provides a pre-embedded edge opening protection connector. It employs a U-shaped groove structure pre-embedded in the wall surrounding the opening, with support rods (first and second support rods) detachably installed at the bottom of the groove. A flexible mesh panel is placed between the two support rods and securely connected to the support rods and the annular hooks on the outer surface of the U-shaped groove using fixing ropes. This significantly improves the ease of construction and reliability of edge opening protection. Specifically, this structural design completely eliminates the cumbersome process of drilling holes in the wall to fix the protection rods, effectively avoiding structural damage to the wall caused by drilling. It also greatly simplifies installation and removal steps, making construction operations more convenient and efficient. More importantly, the application of the flexible mesh panel completely covers the gaps between the support rods, achieving gapless safety shielding of the opening. This fundamentally solves the problem of protection failure that may occur due to excessive gaps in traditional protection rods, ensuring the absolute safety of construction personnel. The entire device utilizes pre-embedded grooves and detachable connections (such as the combination of protrusions and recesses) to achieve rapid, non-destructive, and stable installation and disassembly, comprehensively solving the core defects pointed out in the background technology, such as wall damage, cumbersome operation, inconvenient disassembly, and hidden dangers of protective gaps.

Detailed Implementation

[0025] like Figure 1-4As shown, this utility model provides a pre-embedded edge opening protection connector, including a U-shaped groove 5 pre-embedded in the upper and lower walls 1 around the opening 2. The opening of the U-shaped groove 5 faces the opening 2. The number of U-shaped grooves 5 in the upper wall 1 and the U-shaped grooves 5 in the lower wall 1 are equal and their positions are opposite to each other. A first support rod 3 and a second support rod 6 are respectively arranged in the front-rear direction between the U-shaped grooves 5 in the upper wall 1 and the U-shaped grooves 5 in the lower wall 1. The first support rod 3 and the second support rod 6 are respectively detachably connected to the bottom of the U-shaped groove 5. A flexible mesh plate 18 is arranged between the first support rod 3 and the second support rod 6. The flexible mesh plate 18 is connected to the first support rod 3 and the second support rod 6 respectively by fixing ropes passing through its mesh. An annular hook is provided on the outer surface of the U-shaped groove 5 facing the opening 2. The flexible mesh plate 18 is looped on the annular hook by fixing ropes passing through its mesh.

[0026] The core of this invention lies in replacing the traditional drilling and fixing method with a pre-embedded U-shaped groove structure. During the construction phase of the walls 1 above and below the opening 2, U-shaped grooves 5 are pre-embedded, with their openings facing the opening. The U-shaped grooves in the upper and lower walls are arranged symmetrically in pairs. This pre-embedded design completely avoids the structural damage and cumbersome operation problems caused by drilling into the wall surface in the prior art.

[0027] After construction is completed, the support rods and other components are removed, and the pre-embedded U-shaped groove 5 is poured into the inside of the wall.

[0028] In this utility model, the upper and lower ends of the first support rod 3 are respectively provided with a first protrusion 10, the front end of the bottom of the U-shaped groove 5 is provided with a first recess 11, the first protrusion 10 matches the first recess 11, the upper and lower ends of the second support rod 6 are respectively provided with a second protrusion 15, the rear end of the bottom of the U-shaped groove 5 is provided with a second recess 14, the second protrusion 15 matches the second recess 14.

[0029] In this utility model, the installation process of the protective body is as follows:

[0030] Support rod assembly: Insert the first support rod 3 and the second support rod 6 into the bottom of the U-shaped grooves 5, which are positioned vertically opposite each other. The first protrusion 10 / second protrusion 15 at both ends of the support rods form a snap-fit ​​detachable connection with the first recess 11 / second recess 14 at the bottom of the grooves. This structure enables quick positioning and fixing of the support rods without the need for additional fasteners, significantly improving assembly and disassembly efficiency.

[0031] Flexible protective layer deployment: A flexible mesh panel 18 is installed between the two support rods. The four corners of the mesh panel are secured to the first support rod 3, the second support rod 6, and the annular hooks on the outer surface of the U-shaped groove using fixing ropes. This triple anchoring mechanism ensures that the mesh panel completely covers the opening, eliminating the safety hazards of excessive gaps in traditional protective rods and creating a gapless shield.

[0032] Meanwhile, the optimized design of this utility model to enhance stability is as follows:

[0033] Limiting and anti-displacement structure: Multiple longitudinally symmetrically distributed limiting rods 4 are horizontally welded to the side wall of the U-shaped channel 5. When the U-shaped channel is pre-embedded, the limiting rods are embedded in the wall to form a concrete gripping effect, which greatly improves the channel's pull-out resistance and displacement resistance.

[0034] That is, the side of the U-shaped groove 5 is provided with a plurality of horizontally oriented limiting rods 4, which are located inside the wall 1. The plurality of limiting rods 4 are symmetrically distributed in the longitudinal direction.

[0035] Anti-loosening module for the groove filling: A fixing block 7 is installed between the first and second support rods. The third protrusion 12 at its bottom engages with the third recess 13 at the bottom of the groove, while the fourth protrusion 8 / fifth protrusion 9 at both ends fit into the fourth recess 17 / fifth recess 16 of the support rod. After the three are tightly assembled, they fill the internal space of the U-shaped groove, eliminating the risk of component swaying and enhancing the overall rigidity.

[0036] That is, a fixing block 7 is provided between the first support rod 3 and the second support rod 6. The fixing block 7 is detachably connected to the bottom of the U-shaped groove 5. The fixing block 7, the first support rod 3, and the second support rod 6 can fill the groove of the U-shaped groove 5. A third protrusion 12 is provided on the side of the fixing block 7 facing the bottom of the U-shaped groove 5, and a third recess 13 is provided in the middle of the bottom of the U-shaped groove 5. The third protrusion 12 matches the third recess 13.

[0037] Meanwhile, the front and rear ends of the fixing block 7 are detachably connected to the first support rod 3 and the second support rod 6, respectively. The fixing block 7 has a fourth protrusion 8 and a fifth protrusion 9 at its front and rear ends, respectively. The first support rod 3 has a fourth recess 17, and the second support rod 6 has a fifth recess 16. The fourth protrusion 8 matches the fourth recess 17, and the fifth protrusion 9 matches the fifth recess 16.

[0038] Meanwhile, the ease of construction and maintenance of this utility model is guaranteed as follows:

[0039] Two limiting plates are detachably connected to the upper surface of the opening of the U-shaped groove 5. The two limiting plates, when spliced ​​together, can cover the opening of the U-shaped groove 5. The two limiting plates are connected to the upper surface of the opening of the U-shaped groove 5 by bolts.

[0040] This invention involves installing two interlocking limiting plates at the opening of the U-shaped groove 5 using bolts. Its function is to define the positions of the first support rod 3 and the second support rod 6 during installation, determining their relative positional relationship. The bolts secure the two limiting plates, making them easy to remove later; a simple electric drill is all that's needed for both removal and installation.

[0041] The following table illustrates the technical effects and implementation principles of this utility model.
