[0045] In the description of the utility model, it needs to be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0046] The inventor finds that, when the steel pipe is used for protecting the edge hole, the steel pipe needs to be fixed on the wall by using the expansion bolts, and the safety belt also needs to be fixed by using the expansion bolts. The fixing mode has the following problems: 1. Since the accurate positions of the steel bars and pipelines cannot be accurately obtained when the hole is opened again, the expansion bolts may be hit to the steel bars and the embedded pipelines when the expansion bolts are fixed; 2. The expansion bolts are not easy to be removed after being fixed, and the removal process is easy to cause the damage to the wall; 3. The expansion bolts need to be cut by using the gas cutting or the abrasive wheel when the expansion bolts are removed, which not only wastes the labor, but also wastes a large amount of steel.

[0047] Based on this, the utility model embodiment provides a kind of pre-buried replaceable safety protection kit, refer to Figures 1-6 As shown in the figure, including pre-buried pole 1, multiple anchor bodies 2, two stop nut 3 and functional screw rod assembly;

[0048] The pre-buried pole 1 includes middle section 11 and outer thread section 12 arranged at both ends of the middle section 11;

[0049] The multiple anchor bodies 2 are sleeved on the middle section of the pre-buried pole 1;

[0050] The two stop nut 3 are respectively threadedly connected to the corresponding outer thread section 12;

[0051] The functional screw rod assembly includes two template fixed screw rods 4 and two butterfly buckle pieces (not shown in the figure);

[0052] The template fixed screw rod 4 includes circular table section 41 and screw rod section 42, and the larger-diameter end of the circular table section 41 is integrally connected with the screw rod section 42;

[0053] The circular table section 41 can be detachably connected with the outer thread section 12;

[0054] The two butterfly buckle pieces can be respectively threadedly connected with the corresponding screw rod section 42;

[0055] In the threadedly connected state of the circular table section 41 and the outer thread section 12, the smaller-diameter end of the circular table section 41 abuts against the stop nut 3, the pre-buried pole 1 and the circular table section 41 of the two template fixed screw rods 4 can be pre-buried in the building wall 7, and the larger-diameter end of the circular table section 41 can abut against the inner side of the shaped formwork 8, the screw rod section 42 can pass through the shaped formwork 8, and the butterfly buckle piece can abut against the outer side of the shaped formwork 8.

[0056] In this embodiment, refer to Figure 1 And Figure 3As shown, the anchoring body 2 is a hexagonal ring, and a plurality of anchoring bodies 2 are uniformly distributed in the middle section 11 of the embedded rod 1 for strengthening the gripping force between the embedded rod 1 and the concrete and ensuring the stability of the embedded rod 1 after the concrete is solidified. The length of the embedded rod 1 and the specific number of the anchoring bodies 2 can be reasonably set according to actual needs.

[0057] In this embodiment, the anchoring body 2 is fixed to the embedded rod 1, and the fixed connection mode is welding, so as to ensure that the anchoring body 2 will not fall off.

[0058] In this embodiment, referring to Figure 2 As shown, after the embedded rod 1 and the formwork fixing screw rod 4 are detachably connected, the embedded rod 1 can replace the tension bolt and play a fixing role on the shaped formwork 8 during pouring of the wall 7. Specifically, the two ends of the embedded rod 1 are connected with the upper formwork fixing screw rod 4, so that a structure similar to the tension bolt is obtained. The circular truncated cone section 41 of the embedded rod 1 and the two formwork fixing screw rods 4 is embedded in the wall 7 and can play the role of the tension bolt during pouring of the building wall 7. The screw rod section 42 of the formwork fixing screw rod 4 can pass through the two shaped formworks 8. The circular truncated cone section 41 with a larger diameter is abutted to the inner side of the formwork. The butterfly buckle is threadedly connected to the screw rod section 42 of the formwork fixing screw rod 4 until it is abutted to the outer side of the shaped formwork 8. Therefore, the shaped formwork 8 can be clamped by cooperation of the circular truncated cone section 41 and the butterfly buckle, and the shaped formwork 8 is finally fixed effectively, thereby improving the convenience and accuracy of pouring of the wall.

[0059] In this embodiment, by arranging the grout stopping nut 3, the concrete grout can be effectively prevented from polluting the external thread on the embedded rod 1. After the embedded rod 1 and the circular truncated cone section 41 of the formwork fixing screw rod 4 are embedded in the wall 7, the concrete grout will seep into the space between the formwork fixing screw rod 4 and the external thread section 12 along the thread during pouring of the concrete, thereby polluting the external thread and causing the external thread to fail. In addition, the difficulty of dismounting the formwork fixing screw rod 4 is increased. Therefore, the smaller end of the circular truncated cone section 41 is abutted to the grout stopping nut 3, so that the concrete grout can be effectively prevented from seeping in.

[0060] Further, by using the embedded rod 1 and the formwork fixing screw rod 4 to replace the tension bolt, after pouring of the concrete is completed, the embedded rod 1 is still embedded in the concrete, and the formwork fixing screw rod 4 can be screwed out by using a wrench, that is, the formwork fixing screw rod 4 is dismounted from the embedded rod 1, so that the external thread section 12 at both ends of the embedded rod 1 is partially exposed. The exposed screw rod can be used for connecting the guardrail buckle 62 and the like, thereby realizing protection of the edge hole. Compared with the existing form of fixing the guardrail by using the punched expansion bolt, the embedded rod 1 will not cause damage to the steel bars and the embedded pipeline in the wall, and it is not necessary to perform secondary cutting and repairing of the expansion bolt, thereby improving the operation convenience and being beneficial to protection of the appearance of the wall.

[0061] The embedded replaceable safety protection kit provided by the utility model has the advantages ofFigure 2 and Figure 4 As shown in

[0062] The pre-buried replaceable safety protection kit provided by the utility model can adopt a wrench to screw out the formwork fixing screw rod 4 after the formwork 8 is removed, and the exposed external thread section 12 will not protrude from the wall body 7, thereby avoiding affecting the aesthetic appearance of the wall body.

[0063] In an optional embodiment, referring to Figure 1 、 Figure 2 and Figure 5 , the functional screw rod assembly further comprises a safety belt hanging screw rod 5 for being connected to the external thread section 12 of the pre-buried rod 1, and plays a role of hanging a safety belt. Specifically, the safety belt hanging screw rod 5 comprises a first connecting section 51 and a hanging ring 52 which are integrally connected, wherein the first connecting section 51 can be detachably connected to the external thread section 12, and the hanging ring 52 is used for hanging a safety belt.

[0064] Optionally, the first connecting section 51 is provided with internal threads, which can be threadedly connected to the exposed external thread section 12 of the pre-buried rod 1, thereby realizing firm detachable connection and facilitating on-demand disassembly and assembly.

[0065] In an optional embodiment, referring to Figure 1 、 Figure 2 and Figure 6 , the functional screw rod assembly further comprises a protective rod fixing screw rod 6 for being connected to the external thread section 12 of the pre-buried rod 1, and plays a role of fixing a protective fence (for example, a protective fence in the form of a steel pipe). Specifically, the protective rod fixing screw rod 6 comprises a second connecting section 61 and a buckle 62 which are integrally connected, wherein the second connecting section 61 can be detachably connected to the external thread section 12, and the buckle 62 is used for fixing a protective fence.

[0067] Optionally, the shape of the buckle 62 can be reasonably selected according to the protective rod body which is convenient to take on the construction site. For example, if a conventional steel pipe is used as a protective fence, the buckle 62 can be provided in the form of a ring. Further, the ring of the buckle 62 can be closed and locked by a bolt and a nut combination. Since the bolt has a certain length, the inner diameter of the buckle 62 has a certain adjustment range, and the tightness of the buckle 62 can be adjusted according to the actual needs on the site, thereby improving the construction convenience and flexibility.

[0068] 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] 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.

[0075] Pour the concrete into the formwork 8 and wait for it to solidify;

[0076] After the concrete has hardened, remove the formwork 8 and use a wrench to unscrew the formwork fixing screws 4.
