[0026] like Figure 1 and Figure 2 As shown, in a preferred embodiment of this utility model, this utility model provides a pre-embedded edge protection railing, including a built-in pre-embedded part 2, a wall tie 3, a screw 4, a fixing part 5, a connecting pipe 6, a vertical post 7, and a horizontal post 8. Figure 3As shown, the embedded part 2 includes a sleeve 2-1 and an embedded fastener 2-2. The sleeve 2-1 is embedded in the concrete structure 1 and is composed of two cylindrical tubes with the same axis but different diameters connected together. In this embodiment, the sleeve 2-1 can be composed of two cylindrical steel tubes with different inner diameters. The embedded fastener 2-2 is ring-shaped and fixedly installed at the innermost end of the sleeve 2-1, that is, fixedly connected to the inner wall end of the larger cylindrical tube of the sleeve 2-1 near the center of the concrete structure 1. Moreover, the outer diameter of the embedded fastener 2-2 is larger than the diameter of the smaller cylindrical tube, and the inner diameter of the embedded fastener 2-2 does not exceed the diameter of the smaller cylindrical tube, which can increase the pull-out resistance of the embedded fastener 2-2. The embedded part 2 is generally fixedly installed on the side of the concrete structure 1 in the vertical direction, without occupying the upper edge of the concrete structure, and does not affect the wall, edge, decoration and other processes. Furthermore, the number of built-in embedded parts 2 is usually no less than two, and each pair of built-in embedded parts 2 are set in parallel intervals to ensure that the pull-out resistance of the side of the edge guardrail meets the requirements and to ensure that the edge guardrail is safe and reliable.

[0027] In the device provided by this utility model, the wall-connecting component 3 and the built-in embedded component 2 are connected by a screw 4. For example... Figure 4 As shown, the wall tie 3 includes a clamp 3-1, a bolt assembly 3-2, and a ring seat 3-3. The clamp 3-1 and the ring seat 3-3 are fixedly connected. Two sets of bolt assemblies 3-2 are provided, one on each side of the clamp 3-1. Both ends of the screw 4 have threads of a certain length, and the length of the screw 4 can be adjusted as needed to adapt to different installation requirements. One end of the screw 4 extends into the sleeve 2-1. The built-in fastener 2-2 has an internal thread that matches the thread on one end of the screw 4, and the end of the screw 4 is fixedly connected to the built-in fastener 2-2 by the thread. In other embodiments, the built-in fastener 2-2 can be a nut. The use of the pre-embedded built-in fastener 2-2 and the screw 4 enhances the anchoring effect of the anchor and improves safety. The annular seat 3-3 has an internal thread that matches the thread on the other end of the screw 4. The other end of the screw 4 is fixedly connected to the annular seat 3-3 by the thread, and the end of the screw 4 is pressed against the annular seat 3-3. The design of the screw 4, the built-in fastener 2-2, and the annular seat 3-3 facilitates installation and disassembly, and the components can be reused after disassembly, improving material utilization. The connecting pipe 6 is inserted into the circular cavity of the clamp 3-1, and the clamp 3-1 is tightened by the bolts and nuts of the bolt assembly 3-2. When the clamp 3-1 is tightened, it presses against the connecting pipe 6, achieving a vertical fixed connection between the connecting pipe 6 and the clamp 3-1. Using the bolt assembly 3-2 to fix the connecting pipe 6 facilitates quick installation and disassembly of the connecting pipe 6. In this embodiment, in order to fit the cavity shape of the clamp 3-1, the connecting pipe 6 is generally made of round steel pipe. In other embodiments, the connecting pipe 6 can also be selected from steel pipes of other shapes and strengths that meet the requirements, depending on the actual situation.

[0028] In the device provided by this utility model, the upright 7 and the connecting pipe 6 are arranged vertically, and the upright 7 and the connecting pipe 6 are fixedly connected by the fastener 5. The horizontal bar 8 is perpendicular to the upright 7 and the connecting pipe 6, and is vertically fixedly connected to the upright 7 by the fastener 5. In actual construction, considering production costs and the difficulty of obtaining materials, the upright 7 and the horizontal bar 8 can be made of steel pipes that are easy to process and connect. In other embodiments, the upright 7 and the horizontal bar 8 can be made of other materials that meet the requirements of construction safety and cost, such as carbon fiber pipes. In addition, during construction, multiple horizontal bars 8 can be set according to actual needs to increase the safety of the guardrail. In this embodiment, the fastener 5 is a cross-shaped fastener. The cross-shaped fastener can provide a stable connection, ensuring that the upright 7 and the horizontal bar 8 will not easily loosen or fall off during use, and the cross-shaped fastener can quickly fix the steel pipes together, enabling quick disassembly and reinstallation.

[0029] In practical use, after the reinforcement of the concrete structure 1 is tied, during formwork operations, the embedded part 2 is first placed inside the formwork and fixed. Two or more embedded parts 2 are typically connected vertically, with parallel spacing between each pair. After the concrete structure 1 is poured and reaches the specified strength, the concrete pouring formwork is removed, leaving the embedded part 2 embedded in the concrete structure 1. This pre-embedding method increases the anchoring effect of the anchor, providing greater safety compared to using expansion bolts. Next, the end of the screw rod 4 is inserted into the annular seat 3-3 and tightened, with the end of the screw rod 4 pressing against the annular seat 3-3, thus connecting the screw rod 4 to the wall tie 3. Then, the screw rod 4 is inserted into the sleeve 2-1 of the embedded part 2, and the end of the screw rod 4 is screwed into the embedded fastener 2-2, thus connecting the screw rod 4 to the embedded part 2. Next, the connecting pipe 6 is inserted into the circular cavity formed by the clamp 3-1, and the clamp 3-1 is tightened using the bolts and nuts in the bolt assembly 3-2, fixing the connecting pipe 6 into the clamp 3-1 of the wall tie 3. After the connecting pipe 6 is installed, the upright 7 is vertically fixed to the connecting pipe 6 through the fixing piece 5, and then the horizontal steel pipe 8 is vertically fixed to the upright 7 through the fixing piece 5. After construction is completed, the horizontal bar 8, upright 7, and connecting pipe 6 are disassembled respectively, and then the screw 4 is unscrewed from the built-in embedded part 2, and then the screw 4 is unscrewed from the wall tie 3, thereby removing the entire edge protection railing. After removal, the hole of the sleeve 2-1 of the built-in embedded part 2 is sealed with concrete to prevent leakage to the concrete structure 1, ensuring the integrity and durability of the concrete structure 1.

[0030] The embodiments described above are merely preferred solutions of this utility model, and are not intended to limit the scope of this utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this utility model. Therefore, all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
