[0030] Compared with the prior art, this application has the following beneficial effects:

[0031] This application provides a fixing assembly for pre-embedded bolts, used to fix bolts on building formwork; the fixing assembly for pre-embedded bolts includes a support member and a fixing member;

[0032] One end of the support member can be vertically abutted against the building formwork and the other end is connected to the fixing component. The support member is used to support the fixing component away from the building formwork by a preset distance, so that there is a grouting space between the fixing component and the building formwork.

[0038] The fixing hole has the same diameter as the pre-embedded bolt, so that the fixing hole can vertically fix the pre-embedded bolt to the building formwork.

Since the fixing component of the pre-embedded bolt is perpendicular to the building formwork, when the pre-embedded bolt is fixed by the first and second fixing parts, and the center line of the fixing hole is coaxial with the center line of the hole of the pre-embedded bolt, the pre-embedded bolt is perpendicular to the building formwork, and to a certain extent, the bolt can be prevented from being skewed or misaligned, thereby ensuring the subsequent hoisting effect.

[0050] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0051] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0057] Example 1

[0058] This application provides a fixing component for pre-embedded bolts, used to fix bolts on building formwork. Specifically, during construction, to ensure that precast stairs do not shift during hoisting, bolts are pre-embedded on the upper side of the stair beams on each floor, so that the bolt shanks are exposed outside the building formwork. However, currently, bolt misalignment and other phenomena frequently occur during the bolt pre-embedding process, thus affecting the final hoisting. This application provides a fixing component for pre-embedded bolts, which solves the above-mentioned problems to a certain extent. The structure of the fixing component for pre-embedded bolts is described below in conjunction with... Figure 1 and Figure 2 Detailed explanation.

[0059] Combination Figure 1 and Figure 2 As shown, the fixing assembly for the pre-embedded bolts includes a support member 1 and a fixing member 2.

[0060] Specifically, one end of the support member 1 can be perpendicularly abutted against the building formwork and the other end is connected to the fixing component. The support member 1 is used to support the fixing component away from the building formwork at a preset distance, so that there is a grouting space 3 between the fixing component and the building formwork. In actual use, the pre-embedded bolts are first fixed by the support member 1 and the fixing member 2. Then, the sand and gravel concrete is poured into the holes of the pre-embedded bolts through the grouting space 3 via the pipe.

[0061] Specifically, the fixing assembly has a fixing cylinder 5 that is perpendicularly connected to the support member 1. Furthermore, the support member 1 has a support surface on the side facing away from the building formwork, and the fixing cylinder 5 is perpendicular to the support surface. It is worth noting that the fixing cylinder 5 is only perpendicular to the support surface, but the fixing member 2 and the support member 1 as a whole are arranged in a vertically downward direction. That is to say, the fixing assembly with embedded bolts is perpendicular to the building formwork as a whole.

[0062] Specifically, the fixing cylinder 5 is a cylindrical structure with a cross-section of a first preset diameter; the embedded bolt has a cross-section of a second preset diameter. The first preset diameter and the second preset diameter are the same, so that the fixing cylinder 5 can be fitted with the embedded bolt so that the embedded bolt is perpendicular to the building formwork.

[0063] In summary, during actual use, the support components are oriented towards the building formwork, and then the fixing cylinder 5 is directly fitted onto the pre-embedded bolts exposed on the building formwork. Since the fixing components of the pre-embedded bolts are perpendicular to the building formwork, when the fixing cylinder 5 is fitted onto the pre-embedded bolts, it can ensure that the pre-embedded bolts are perpendicular to the building formwork, which can prevent the bolts from tilting or shifting to a certain extent, thereby ensuring the subsequent hoisting effect.

[0064] It is worth noting that in actual use, the center line 17 of the fixed cylinder 5 should be coaxial with the center line of the hole of the pre-embedded bolt.

[0065] In this embodiment, further, combined with Figure 2 As shown, the fixing assembly includes a fixing base 4 and a fixing cylinder 5 that can serve as a fixing cylinder 5.

[0066] Specifically, the fixing base 4 is vertically connected to the supporting member 1; the fixing cylinder 5 is disposed on the side of the fixing base 4 away from the supporting member 1 and extends along a first direction; the first direction here refers to the vertically upward direction. Furthermore, the fixing cylinder 5 has a certain height; preferably, the height of the fixing cylinder 5 is the same as the height of the pre-embedded bolts exposed on the building formwork, that is, all the pre-embedded bolts exposed on the building formwork are fixed by the fixing cylinder 5, thereby making the fixing effect of the pre-embedded bolts better.

[0067] Specifically, the fixing base 4 has a first fixing hole 6 with a first preset diameter, and the fixing cylinder 5 has a second fixing hole 15 extending along a first direction and having a first preset diameter. The first fixing hole 6 and the second fixing hole 15 are connected together. That is, during the process of installing the pre-embedded bolt, the pre-embedded bolt will first pass through the first fixing hole 6, and then pass through the second fixing hole 15.

[0068] In this embodiment, further, combined with Figure 1 As shown, the support member 1 includes support rods 7; the support rods 7 are arranged at equal intervals along the edge 14 of the fixed seat 4.

[0069] Specifically, the fixed base 4 is a cube, and four support rods 7 are provided. The four support rods 7 are respectively located at the four corners of the fixed base 4, thereby ensuring the stability of the fixed base 4 supported by the support rods 7.

[0070] In this embodiment, further, combined with Figure 2 As shown, the support member 1 also includes a locking member 8.

[0071] Specifically, one end of the support rod 7 is perpendicularly abutted against the building formwork, and the other end passes perpendicularly through the fixed seat 4.

[0072] Specifically, the locking element 8 is threadedly connected to the support rod 7, and the locking element 8 can lock the portion of the support rod 7 that passes through the fixed seat 4 to the end face of the fixed seat 4 away from the support rod 7. The length of the support rod 7 between the building formwork and the fixed seat 4 can be adjusted by the locking element 8. Specifically, in actual working conditions, the end face of the building formwork may not be horizontal, for example, the end face of the building formwork may have a protrusion. In order to ensure that the fixed seat 4 is horizontal, and more importantly, to ensure that the center line 17 of the fixed cylinder 5 is coaxial with the center line of the hole of the pre-embedded bolt, the locking element 8 and the support rod 7 can be adjusted. Specifically, the length between the building formwork and the fixed seat 4 is shortened at the protrusion of the support rod 7, that is, the support rod 7 is screwed on so that the support rod 7 passes through the fixed seat 4 more, ensuring that the fixed seat 4 is horizontal and that the center line 17 of the fixed cylinder 5 is coaxial with the center line of the hole of the pre-embedded bolt.

[0073] Furthermore, the locking element 8 is a locking nut 9, and the locking nut 9 has internal threads; the outer side wall of the support rod 7 has external threads so that the locking nut 9 is threadedly connected to the support rod 7.

[0074] In this embodiment, both the support member 1 and the fixing component are made of plastic. Plastic support members 1 and fixing components offer good insulation and are low in cost.

[0075] Example 2

[0076] This embodiment provides another structure that can solve the technical problem proposed in Embodiment 1, which will be described below in conjunction with... Figures 3-5 The fixing assembly of the pre-embedded bolts in this embodiment is described in detail.

[0077] The pre-embedded bolt fixing assembly is used to fix the bolts on the building formwork; the pre-embedded bolt fixing assembly includes a support member 1 and a fixing member 2.

[0078] Specifically, one end of the support member 1 can be perpendicularly abutted against the building formwork and the other end is connected to the fixing component. The support member 1 is used to support the fixing component away from the building formwork at a preset distance, so that there is a grouting space 3 between the fixing component and the building formwork. In actual use, the pre-embedded bolts are first fixed by the support member 1 and the fixing member 2. Then, the sand and gravel concrete is poured into the holes of the pre-embedded bolts through the grouting space 3 via the pipe.

[0079] Specifically, the fixing component 2 includes a first fixing part 10 and a second fixing part 11. The first fixing part 10 and the second fixing part 11 are symmetrically arranged about the center line 17 of the supporting component 1, and the side walls facing the first fixing part 10 and the second fixing part 11 are surrounded by fixing holes 12. The fixing holes 12 have the same diameter as the pre-embedded bolts so that the fixing holes 12 can vertically fix the pre-embedded bolts to the building formwork.

[0080] In summary, during actual use, the first fixing part 10 is placed on one side of the pre-embedded bolt, and the second fixing part 11 is placed on the other side of the pre-embedded bolt, so that the first fixing part 10 and the second fixing part 11 enclose the pre-embedded bolt; and ensure that the center line 17 of the fixing hole 12 is coaxial with the center line of the hole of the pre-embedded bolt (this can be observed visually by the on-site operator). Since the fixing component of the pre-embedded bolt is perpendicular to the building formwork, when the pre-embedded bolt is fixed by the first fixing part 10 and the second fixing part 11, and the center line 17 of the fixing hole 12 is coaxial with the center line of the hole of the pre-embedded bolt, the pre-embedded bolt can be made perpendicular to the building formwork, and to a certain extent, the bolt can be prevented from being skewed or misaligned, thereby ensuring the subsequent hoisting effect.

[0081] In this embodiment, further, combined with Figure 3 As shown, the fixing assembly of the pre-embedded bolt also includes a connector 16, which is preferably a connecting bolt. After the first fixing part 10 and the second fixing part 11 fasten the pre-embedded bolt, the connecting bolt can pass through the second fixing part 11 from the first fixing part 10.

[0082] Furthermore, the first fixing part 10 and the second fixing part 11 are provided with connecting holes at opposite positions. The connecting bolt can be passed from the connecting hole on the first fixing part 10 to the connecting hole on the second fixing part 11 to connect the first fixing part 10 and the second fixing part 11 together.

[0083] Furthermore, it also includes a hanging chain, through which the screw head end of the connecting bolt is fixed to the outer wall of the first fixing part 10 or the outer wall of the second fixing part 11 to prevent the connecting bolt from being lost.

[0084] In this embodiment, further, combined with Figure 4 and Figure 5 As shown, the first fixing part 10 includes an arc-shaped plate 13 and an edge 14; the arc-shaped plate 13 extends along a first direction, and the edge 14 is disposed at one end of the arc-shaped plate 13 near the supporting member 1, and the edge 14 is perpendicularly connected to the arc-shaped plate 13; the supporting member 1 is perpendicularly connected to the edge 14.

[0085] Specifically, the arc-shaped plate 13 on the first fixing part 10 and the arc-shaped plate 13 on the second fixing part 11 are fastened together to form a fixing hole 12.

[0086] It is worth noting that the specific structure of support component 1 is the same as in Embodiment 1, and will not be described in detail here.

[0087] In this embodiment, the arc-shaped plates 13 with fixing holes 12 each have threads that are compatible with the external threads of the pre-embedded bolts, so that when the pre-embedded bolts are fixed using the fixing holes 12, the threads of the fixing holes 12 correspond one-to-one with the pre-embedded bolts, thereby improving the fixing effect of the pre-embedded bolts.

[0088] It should also be noted that the fixing components of the pre-embedded bolts can be reused, which reduces the degree of difficulty to some extent.

[0090] This application also provides a fixing device, including the fixing assembly with the pre-embedded bolts described above. Therefore, it possesses all the beneficial effects of the fixing assembly with the pre-embedded bolts described above, and will not be elaborated further.

[0091] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
