[0030] The beneficial effects of the above-described technical solutions provided in the embodiments of the present invention include at least the following:

[0031] This invention provides a novel pre-embedded replaceable safety protection fastening kit. By detachably connecting the pre-embedded rod and the template fixing screw, it can replace tie bolts and fix the template during wall pouring. Specifically, the threaded sections of the template fixing screws at both ends of the pre-embedded rod can pass through the templates on both sides. The templates are clamped by the cooperation of the frustum section and the butterfly fastener, thus achieving template fixation. After the concrete is poured, the pre-embedded rod remains embedded in the concrete. The template fixing screws can be unscrewed with a wrench, exposing the external threaded sections at both ends of the pre-embedded rod. The exposed screws can be used to connect guardrail clips, etc., to achieve edge protection for openings. Compared to the existing method of fixing guardrails with driven expansion bolts, this method does not damage the reinforcing steel and pre-embedded pipelines within the wall, and eliminates the need for secondary cutting and repair of expansion bolts.

[0032] This invention provides a novel pre-embedded replaceable safety protection fastening kit. The anchor body strengthens the bond between the pre-embedded rod and the concrete. By fixing anchor bars to the anchor body, stress is distributed more evenly within the concrete, effectively transferring and dispersing stress between the pre-embedded rod and the wall, reducing the risk of wall damage. Furthermore, by fitting an elastic body at the end of the anchor bar, its elastic deformation absorbs and mitigates the impact of vibration, resulting in a more uniform stress distribution and reducing stress concentration, further avoiding the risk of damage caused by stress concentration. Moreover, the anchor bar can bear some or all of the external force, thereby reducing the burden on other structural components and improving the overall load-bearing capacity and durability of the novel pre-embedded replaceable safety protection fastening kit.

The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0044] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0045] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," "far," "near," "front," and "rear," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] The inventors discovered that using steel pipes for edge protection of openings requires fixing the pipes to the wall with expansion bolts, and the safety belts also need to be secured with expansion bolts. This fixing method has the following problems: 1. Because the exact location of the reinforcing bars and pipelines cannot be accurately determined when making secondary openings, the expansion bolts may hit the reinforcing bars and embedded pipelines during fixing; 2. Expansion bolts are not easy to remove after fixing, and the removal process can easily damage the wall; 3. Removing expansion bolts requires gas cutting or abrasive wheel cutting, which not only wastes labor but also a large amount of steel.

[0048] Based on this, embodiments of the present invention provide a novel pre-embedded replaceable safety protection fastening kit, referring to... Figures 1-6 As shown, it includes a pre-embedded rod 1, multiple anchor bodies 2, two grout-stopping nuts 3, and a functional screw assembly;

[0049] The embedded rod 1 includes an intermediate section 11 and externally threaded sections 12 disposed at both ends of the intermediate section 11;

[0050] The plurality of anchor bodies 2 are sleeved in the middle section of the pre-embedded rod 1;

[0051] At least two anchor bars 9 are fixedly connected to the anchor body 2 located in the middle;

[0052] Each of the anchor bars 9 is fitted with an elastic body 10 at the end away from the anchor body 2;

[0053] The two anti-grouting nuts 3 are respectively threaded to the corresponding external thread section 12;

[0054] The functional lead screw assembly includes two template fixing lead screws 4 and two butterfly fasteners (not shown in the figure);

[0055] The template fixing screw 4 includes a frustum section 41 and a screw section 42, and the larger diameter end of the frustum section 41 is integrally connected to the screw section 42.

[0056] The frustum section 41 can be detachably connected to the external thread section 12;

[0057] The two butterfly fasteners can be threadedly connected to the corresponding screw section 42 respectively;

[0058] When the frustum section 41 and the external thread section 12 are threadedly connected, the smaller diameter end of the frustum section 41 abuts against the grout-stopping nut 3. The frustum sections 41 of the embedded rod 1 and the two template fixing screws 4 can be embedded in the building wall 7. Furthermore, the larger diameter end of the frustum section 41 can abut against the inner side of the shaped template 8. The screw section 42 can pass through the shaped template 8, and the butterfly fastener can abut against the outer side of the shaped template 8.

[0059] In this embodiment of the invention, reference is made to Figure 1 and Figure 3 As shown, the anchor body 2 is a hexagonal ring, and multiple anchor bodies 2 are axially evenly distributed in the middle section 11 of the embedded rod 1. This is used to strengthen the bond between the embedded rod 1 and the concrete, ensuring the stability of the embedded rod 1 after the concrete has solidified. The length of the embedded rod 1 and the specific number of anchor bodies 2 can be reasonably set according to actual needs.

[0060] In this embodiment of the invention, the anchor body 2 is fixed to the pre-embedded rod 1, and the fixing connection is made by welding to ensure that the anchor body 2 will not fall off.

[0061] In this embodiment of the invention, reference is made to Figure 3 As shown, there are at least two anchor bars 9, evenly distributed around the outer periphery of the anchor body 2, arranged radially with the anchor body 2 as the center. This increases the contact area between the new pre-embedded replaceable safety protection fastening kit and the wall, making the stress distribution in the concrete more uniform. This effectively realizes the transmission and dispersion of stress between the pre-embedded rod 1 and the wall, reducing the risk of wall damage. Furthermore, by fitting an elastic body 10 at the end of the anchor bar 9, its elastic deformation can absorb and mitigate the impact of vibration, making the stress distribution more uniform, thereby reducing stress concentration and further avoiding the risk of damage caused by stress concentration. Moreover, the anchor bar 9 can bear part or all of the external force, thereby reducing the burden on other structural components and improving the load-bearing capacity and durability of the entire new pre-embedded replaceable safety protection fastening kit.

[0062] In this embodiment of the invention, the anchor bar 9 and the anchor body 2 are fixedly connected by means including but not limited to welding, thereby ensuring the stability of the embedded rod. Adhesive can be applied between the elastic body 10 and the anchor bar 9 to enhance connection stability.

[0063] In this embodiment of the invention, reference is made to Figure 2As shown, the embedded rod 1 and the template fixing screw rod 4 are detachably connected, which can replace the tie bolts and fix the shaped template 8 during the pouring of the wall 7. Specifically, the two ends of the embedded rod 1 are connected to the template fixing screw rod 4, thus obtaining a structure similar to the tie bolt. The truncated cone section 41 of the embedded rod 1 and the two template fixing screw rods 4 are embedded in the wall 7, which can act as tie bolts during the pouring of the building wall 7. The screw section 42 of the template fixing screw rod 4 can pass through the two shaped templates 8. The larger diameter end of the truncated cone section 41 abuts against the inner side of the template. The butterfly fastener is threaded to the screw section 42 of the template fixing screw rod 4 until it abuts against the outer side of the shaped template 8. Thus, the shaped template 8 can be clamped by the cooperation of the truncated cone section 41 and the butterfly fastener, and the shaped template 8 can be effectively fixed, improving the convenience and accuracy of the wall pouring.

[0064] In this embodiment of the invention, by setting a grout-stopping nut 3, the contamination of the external threads on the embedded rod 1 by concrete grout is effectively prevented. After the embedded rod 1, together with the frustum section 41 of the formwork fixing screw 4, is embedded in the wall 7, during the concrete pouring process, concrete grout will seep along the threads into the space between the formwork fixing screw 4 and the external thread section 12, contaminating the external threads and causing them to fail. This will also increase the difficulty of disassembling the formwork fixing screw 4. Therefore, the grout-stopping nut 3 is abutted at the end of the frustum section 41 with a smaller diameter, thereby effectively preventing concrete grout from seeping in.

[0065] Furthermore, by replacing tie bolts with embedded rods 1 and template fixing screws 4, after the concrete pouring is completed, the embedded rods 1 remain embedded in the concrete, and the template fixing screws 4 can be unscrewed with a wrench. That is, the template fixing screws 4 are removed from the embedded rods 1, exposing the external threaded sections 12 at both ends of the embedded rods 1. The exposed screws can be used to connect guardrail clips 62, etc., to achieve edge protection. Compared with the existing method of fixing guardrails with driven expansion bolts, this method will not damage the steel bars and embedded pipelines in the wall, and there is no need for secondary cutting and repair of expansion bolts, which improves the convenience of operation and helps to ensure the aesthetics of the wall.

[0066] The novel pre-embedded replaceable safety protection fastening kit provided by this invention refers to... Figure 2 As shown, the smaller diameter end of the frustum section 41 of the template fixing screw 4 is far away from the template 8, while the larger diameter end is close to the template 8. This can effectively reduce the resistance when the template fixing screw 4 is screwed out, thereby avoiding damage to the wall.

[0067] The novel pre-embedded replaceable safety protection fastening kit provided by this invention allows the template fixing screw 4 to be unscrewed with a wrench after the template 8 is removed, and the exposed external thread section 12 will not protrude from the wall 7, thus avoiding affecting the aesthetics of the wall.

[0068] In an optional implementation, refer to Figure 1 , Figure 2 and Figure 5 As shown, the functional lead screw assembly also includes a seat belt fastening lead screw 5, which is used to connect to the external thread section 12 of the embedded rod 1 to fasten the seat belt. Specifically, the seat belt fastening lead screw 5 includes an integrally connected first connecting section 51 and a hanging ring 52, wherein the first connecting section 51 can be detachably connected to the external thread section 12, and the hanging ring 52 is used to fasten the seat belt.

[0069] Optionally, the first connecting section 51 is provided with an internal thread, which can be threadedly connected to the exposed external thread section 12 of the embedded rod 1, thereby achieving a firm detachable connection and facilitating disassembly and assembly as needed.

[0070] In an optional implementation, refer to Figure 1 , Figure 2 and Figure 6 As shown, the functional lead screw assembly also includes a guardrail fixing lead screw 6, which is used to connect to the external threaded section 12 of the embedded rod 1 to fix the guardrail (e.g., a guardrail in the form of a steel pipe). Specifically, the guardrail fixing lead screw 6 includes an integrally connected second connecting section 61 and a buckle 62, wherein the second connecting section 61 can be detachably connected to the external threaded section 12, and the buckle 62 is used to fix the guardrail.

[0071] Optionally, the second connecting section 61 is provided with an internal thread, which can be threadedly connected to the exposed external thread section 12 of the pre-embedded rod 1, thereby achieving a firm and detachable connection, which is convenient for disassembly and assembly as needed.

[0072] Optionally, the shape of the clip 62 can be reasonably selected according to the protective railing body that is conveniently available at the construction site. For example, if a conventional steel pipe is used as the guardrail, the clip 62 can be set as a ring. Furthermore, the ring of the clip 62 can be closed and locked by a combination of bolts and nuts. Since the bolt has a certain length, the inner diameter of the clip 62 has a certain adjustment range, and the tightness of the clip 62 can be adjusted according to the actual needs of the site, which improves the convenience and flexibility of construction.

[0073] In an optional implementation, refer to Figure 1 , Figure 2 and Figure 4 As shown, the frustum section 41 of the template fixing screw 4 is provided with an internal thread, which can be threadedly connected to the external thread section 12 of the pre-embedded rod 1, thereby achieving a firm and detachable connection.

[0074] In an optional implementation, in order to ensure that the template fixing screw 4, the safety belt fastening screw 5 and the guard rod fixing screw 6 can be stably connected to the embedded rod 1, the length of any external threaded section 12 of the embedded rod 1 is greater than 8cm, and the length of the frustum section 41, the first connecting section 51 and the second connecting section 61 is greater than or equal to 5cm.

[0077] The frustum sections 41 of the two template fixing screws 4 are threaded to the two external thread sections 12 of the embedded rod 1, and the grout stop nut 3 is tightened to abut against the frustum section 41.

[0078] The pre-embedded rod 1 and the frustum sections 41 of the two template fixing screw rods 4 are embedded together in the building wall 7, and the screw sections 42 of the two template fixing screw rods 4 extend out of the two side templates 8 respectively, with the larger diameter end of the two frustum sections 41 abutting the inner side of the template 8 respectively.

[0079] Connect the butterfly fastener to the two screw sections 42 until it abuts against the outside of the shaping template 8, thereby fixing the shaping template 8.

[0080] Pour the concrete into the formwork 8 and wait for it to solidify;

[0081] After the concrete has hardened, remove the formwork 8 and use a wrench to unscrew the formwork fixing screws 4.

[0082] In an optional implementation, when workers are required to wear safety belts, the process of fastening the safety belt using the novel pre-embedded replaceable safety protection fastening kit provided by this invention may specifically include:
