[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] The embedded anchor bolt fixing device provided by the embodiment of the present invention is used to fix multiple anchor bolts 3 embedded in the steel cage template 1, wherein the lower and middle parts of the multiple anchor bolts 3 are embedded in the steel cage template 1, and the upper part (the part with the external thread) is located on the outer side of the upper end surface of the steel cage template 1. Figure 1 As shown, the device includes: a support component, a multi-layer fixed template and a fixed component;

[0033] The support assembly is used to span and be fixed to the upper end surface of the reinforcement cage template 1;

[0034] The multiple layers of fixed formwork are respectively fixed to the supporting components, and each layer of the fixed formwork is provided with a plurality of through bolt positioning holes, and the spacing between two adjacent bolt positioning holes in the plurality of bolt positioning holes meets the preset size requirements, and the multiple bolt positioning holes of two adjacent layers of the fixed formwork are coaxially distributed one by one, so that the upper parts of the multiple anchor bolts 3 can pass through the multiple bolt positioning holes of the multiple layers of the fixed formwork one by one;

[0035] The fixing assembly is used to fix the upper portions of the plurality of anchor bolts 3 one by one to the uppermost fixed formwork after the upper portions of the plurality of anchor bolts 3 pass through the plurality of bolt positioning holes of the multi-layer fixed formwork one by one.

[0036] It should be noted that if Figure 1As shown, the support assembly is used to be fixed across the upper end surface of the steel cage template 1; the multiple layers of fixed templates are respectively fixed on the support assembly; wherein, each layer of fixed template is provided with a plurality of through bolt positioning holes, and the spacing between each two adjacent bolt positioning holes in the multiple bolt positioning holes meets the preset size requirements, and the multiple bolt positioning holes of each two adjacent layers of fixed templates are coaxially distributed one by one, ensuring that the upper parts of the multiple anchor bolts 3 can pass through the multiple bolt positioning holes of the multiple layers of fixed templates one by one, that is, multi-layer positioning is achieved through the multiple bolt positioning holes of the multiple layers of fixed templates one by one on the upper parts of the multiple anchor bolts 3, so as to determine the relative sizes of the multiple anchor bolts 3, and then the upper parts of the multiple anchor bolts 3 are fixed one by one to the uppermost fixed template through the fixing assembly, that is, on the multiple anchor bolts After the upper part of the bolt 3 is positioned, it is fixed so that the relative dimensions of the multiple anchor bolts 3 after pre-embedding meet the requirements, ensuring that the frame column or equipment can be adapted and installed with the multiple anchor bolts 3, and the upper parts of the multiple anchor bolts 3 are positioned and fixed in multiple layers through this device, which effectively ensures the relative dimensions of the upper parts of the multiple anchor bolts 3, so that during the pouring process, the accuracy of the pre-embedded anchor bolts 3 can be guaranteed to the greatest extent; in addition, the multiple bolt positioning holes of the two adjacent layers of fixed formwork need to be drilled at the same time to ensure the coaxiality of the bolt positioning holes of the upper fixed formwork and the corresponding bolt positioning holes of the lower fixed formwork; and the aperture of the bolt positioning holes of each layer of fixed formwork is adapted to the upper diameter of the anchor bolt 3, ensuring that the upper part of the anchor bolt 3 can be adapted to pass through the bolt positioning holes.

[0037] That is to say, the embedded anchor bolt fixing device provided by the present solution, the multi-layer fixed formwork is fixed to the upper port of the steel cage formwork 1 through the supporting assembly, and the upper parts of the multiple anchor bolts 3 are positioned one by one by the multiple bolts of the multi-layer fixed formwork, and then the upper parts of the multiple anchor bolts 3 are fixed one by one to the uppermost fixed formwork through the fixing assembly, thereby achieving multi-layer positioning and fixation of the upper parts of the multiple anchor bolts 3, which can effectively ensure the relative sizes of the upper parts of the multiple anchor bolts 3, thereby helping to determine the relative sizes of the multiple anchor bolts 3, so that during the pouring process, the accuracy of the embedded anchor bolts 3 can be maximized; of course, this fixing method is also conducive to controlling the verticality of the multiple anchor bolts 3.

[0038] It can be seen that the embedded anchor bolt fixing device is used to be fixed on the upper end surface of the steel cage formwork 1, and is used to realize multi-layer positioning and fixation of multiple anchor bolts 3 located on the upper part of the outer side of the steel cage formwork 1, which can effectively ensure the relative size of the upper part of the multiple anchor bolts 3, so that during the pouring process, the accuracy of the embedded multiple anchor bolts 3 can be maximized.

[0039] In this program, if Figure 1 As shown, the multi-layer fixed template includes: an upper fixed template 5 and a lower fixed template 6;

[0040] The upper fixed template 5 and the lower fixed template 6 are respectively fixed to the top and the bottom of the support assembly, and the upper fixed template 5 and the lower fixed template 6 are respectively provided with the plurality of bolt positioning holes as described above, and the upper fixed template 5 is the uppermost fixed template.

[0041] In addition, the lower fixed template 6 can also be fixed to the top of the support assembly, and the upper fixed template 5 can also be fixed above the lower fixed template 6, and the upper fixed template 5 and the lower fixed template 6 are respectively provided with the plurality of bolt positioning holes as described above, and the upper fixed template 5 is the uppermost fixed template. Among them, the upper fixed template 5 and the lower fixed template 6 can be uniformly fixed with a plurality of cushion blocks therebetween.

[0042] It should be noted that, whether the upper fixed template 5 and the lower fixed template 6 are respectively fixed to the top and the bottom of the support assembly, or the lower fixed template 6 is fixed to the top of the support assembly and the upper fixed template 5 is fixed above the lower fixed template 6, both are to realize two-layer positioning of the upper portions of the plurality of foundation bolts 3; and the plurality of bolt positioning holes of the upper fixed template 5 and the plurality of bolt positioning holes of the lower fixed template 6 are coaxially distributed one-to-one, so that the upper portions of the plurality of foundation bolts 3 pass through the plurality of bolt positioning holes of the lower fixed template 6 and the upper fixed template 5 one-to-one; and after the plurality of foundation bolts 3 pass through the plurality of bolt positioning holes of the lower fixed template 6 and the upper fixed template 5 one-to-one, the fixing assembly is used to fix the upper portions of the plurality of foundation bolts 3 to the upper fixed template 5.

[0043] Among them, when the upper fixed template 5 and the lower fixed template 6 are respectively fixed to the top and the bottom of the support assembly, it is equivalent to separate the upper fixed template 5 and the lower fixed template 6 by the support assembly, so as to increase the layer distance of the two-layer positioning of the upper portions of the foundation bolts 3, so as to better ensure the relative size of the upper portions of the plurality of foundation bolts 3, and better determine the relative size of the plurality of foundation bolts 3. In this case, the lower fixed template 6 is located in the reinforcement cage template 1 and is flush with the upper end surface of the reinforcement cage template 1, so as to be in contact with the concrete; of course, after the concrete poured in the reinforcement cage template 1 solidifies, the lower fixed template 6 needs to be disassembled from the concrete; in addition, when the lower fixed template 6 is fixed to the top of the support assembly and the upper fixed template 5 is fixed above the lower fixed template 6, that is, the lower fixed template 6 and the upper fixed template 5 are sequentially and spacedly fixed to the top of the support assembly, the lower fixed template 6 can be avoided from being in contact with the concrete poured in the reinforcement cage template 1, so as to facilitate the disassembly of the lower fixed template 6.

[0044] Specifically, as described above, the upper fixed template 5 and the lower fixed template 6 are respectively fixed to the top and the bottom of the support assembly;

[0045] As Figure 1 and Figure 4 shown, the support assembly comprises two support bars 2 arranged in parallel;

[0046] The two support bars 2 are respectively arranged across the upper end surface of the reinforcement cage template 1;

[0047] The upper fixed template 5 is fixed to the top of the two support bars 2, and the lower fixed template 6 is fixed to the bottom of the two support bars 2. The multiple bolt positioning holes of the upper fixed template 5 or the lower fixed template 6 are distributed in a staggered manner with the two support bars 2.

[0048] As Figure 1 shown, the two support bars 2 arranged in parallel are respectively arranged across the upper end surface of the reinforcement cage template 1 to provide stable support for the upper fixed template 5 and the lower fixed template 6. The upper fixed template 5 and the lower fixed template 6 are respectively fixed to the top and the bottom of the two support bars 2. The multiple bolt positioning holes of the upper fixed template 5 or the lower fixed template 6 are distributed in a staggered manner with the two support bars 2, so as to avoid the upper part of the multiple foundation bolts 3 interfering with the two support bars 2. That is, the support assembly is designed in this way, which can make the embedded foundation bolt fixing device simple in structure and convenient to assemble.

[0049] Further, as Figure 1 shown, the two ends of the two support bars 2 are each fixed to the upper end surface of the opposite two sides of the reinforcement cage template 1 by the first rivet 7; as Figure 1 shown, the first end of the two support bars 2 is fixed to the upper end surface of the first side of the reinforcement cage template 1 by the first rivet 7, and the second end is fixed to the upper end surface of the second side of the reinforcement cage template 1 by the first rivet 7. The first side and the second side of the reinforcement cage template 1 are arranged in opposite directions; that is, the two ends of the two support bars 2 are riveted to the upper end surface of the opposite two sides of the reinforcement cage template 1;

[0050] As Figure 3 shown, the upper fixed template 5 is fixed to the top of the middle part of the two support bars 2 by the second rivet 8, and the lower fixed template 6 is fixed to the bottom of the middle part of the two support bars 2 by the third rivet. As Figure 3As shown, the first portion of the upper fixed formwork 5 is fixed to the top of the middle portion of one support bar 2 by two second rivets 8, and the second portion is fixed to the top of the middle portion of the other support bar 2 by two second rivets 8; the first portion of the lower fixed formwork 6 can be fixed to the bottom of the middle portion of one support bar 2 by two third rivets, and the second portion can be fixed to the bottom of the middle portion of the other support bar 2 by two third rivets. In other words, the upper fixed formwork 5 is riveted to the top of the middle portion of the two support bars 2, and the lower fixed formwork 6 is riveted to the bottom of the middle portion of the two support bars 2. In this way, the upper fixed formwork 5 and the lower fixed formwork 6 can be fastened to the top and bottom of the middle portion of the two support bars 2, respectively, and the two ends of the two support bars 2 are fastened to the upper end surfaces of the two opposite sides of the steel cage formwork 1. In other words, the pre-embedded anchor bolt fixing device is fastened across the upper end surface of the steel cage formwork 1, thereby simplifying the assembly of the pre-embedded anchor bolt fixing device and facilitating its installation and fixation on the upper end surface of the steel cage formwork 1.

[0051] Furthermore, if Figure 1 As shown, the multiple bolt positioning holes of the upper fixed template 5 are located one by one at multiple corners of the upper fixed template 5;

[0052] The multiple bolt positioning holes of the lower fixed template 6 are located at multiple corners of the lower fixed template 6; that is, the multiple bolt positioning holes of each fixed template are located at multiple corners of the fixed template;

[0053] like Figure 2 and Figure 3 As shown, the middle portion of the two support bars 2 is located inside the multiple bolt positioning holes of the upper fixed template 5 or the lower fixed template 6.

[0054] Among them, such as Figure 1 As shown, the number of bolt locating holes in the upper fixed formwork 5 and the lower fixed formwork 6 can be four. The four bolt locating holes of the upper fixed formwork 5 are located at the four corners of the upper fixed formwork 5, and the four bolt locating holes of the lower fixed formwork 6 are located at the four corners of the lower fixed formwork 6. Two of the four bolt locating holes of the upper fixed formwork 5 or the lower fixed formwork 6 are located on the outside of one support bar 2, and the other two bolt locating holes are located on the outside of the other support bar 2. In other words, the multiple bolt locating holes of each layer of the fixed formwork are opened one by one at the multiple corners of the fixed formwork, and the middle portions of the two support bars 2 are located inside the multiple bolt locating holes of each layer of the fixed formwork, which can better ensure the relative sizes of the upper portions of the multiple anchor bolts 3. This can help to maximize the accuracy of the pre-embedded multiple anchor bolts 3 during the pouring process.

[0055] In this program, if Figure 1 As shown, the support bars 2 include support timbers. Specifically, using support timbers as the support bars 2 not only facilitates the support bars 2 being positioned across the upper end surface of the reinforcement cage formwork 1, but also facilitates the riveting of the upper and lower fixed formworks 5 and 6 to the top and bottom ends of the two support bars 2, respectively. Of course, timbers at the construction site can also be used as support timbers, which can reduce the cost of the embedded anchor bolt fixing device.

[0056] Specifically, if Figure 1 As shown, the fixing assembly includes a plurality of nuts 4;

[0057] After the upper portions of the multiple anchor bolts 3 are passed through the multiple bolt positioning holes of the multiple layers of fixed formwork, the multiple nuts 4 are tightened one by one against the upper portions of the multiple anchor bolts 3, thereby securing (locking) the upper portions of the multiple anchor bolts 3 to the topmost fixed formwork, that is, securing the upper portions of the multiple anchor bolts 3 to the upper fixed formwork 5. Of course, after being tightened, the multiple nuts 4 are all located on the upper surface of the upper fixed formwork 5, and a certain length of thread (external thread) of the upper portions of the multiple anchor bolts 3 is exposed. In other words, using multiple nuts 4 as a fixing component not only simplifies the fixing of the upper portions of the multiple anchor bolts 3, but also facilitates adjusting the height of the upper portions of the multiple anchor bolts 3 exposed from the upper end surface of the reinforcement cage formwork 1.

[0058] Furthermore, the fixing assembly further includes a plurality of gaskets;

[0059] Multiple washers are fitted onto the tops of the anchor bolts 3 and positioned between the nuts 4 and the topmost fixed formwork, that is, between the nuts 4 and the upper surface of the upper fixed formwork 5. In other words, by providing washers between each nut 4 and the upper surface of the upper fixed formwork 5, the nuts 4 are prevented from crushing the upper surface of the upper fixed formwork 5 when tightened onto the anchor bolts 3, thereby ensuring the durability of the upper fixed formwork 5.

[0060] In addition, it should be noted that when pouring concrete, the concrete pouring surface uses the upper end surface of the steel cage formwork 1 as the dividing interface. After the concrete curing period, the first rivet 7 on the supporting wooden square is removed, the nut 4 and the gasket on the anchor bolt 3 are removed, and the upper fixed formwork 5 and the lower fixed formwork 6 are removed respectively. The fixing device is then disassembled, and the disassembly process is simple and effective. Of course, after the disassembly is completed, the relative size of the anchor bolt 3 can be remeasured.

[0061] Among them, after the concrete pouring is completed, the demoulding process of this fixing device is simple, which can save labor costs, and the removed upper fixed formwork, lower fixed formwork and wooden planks can be used in other fixing devices, saving material loss; and after the concrete pouring is completed, the accuracy of the anchor bolts can be re-measured, and the error is within ±2mm, which is a high precision.

[0062] The fixing device can be assembled into one piece first, and then the upper parts of the multiple anchor bolts 3 are passed through the multiple bolt positioning holes of the fixing device one by one, and the upper parts of the multiple anchor bolts 3 are fixed to the top of the fixing device through multiple nuts, and then the fixing device with the multiple anchor bolts 3 installed is installed on the upper end surface of the steel cage template 1; in this process, the relative sizes of the center lines of the multiple anchor bolts 3 can be adjusted quickly and efficiently as a whole, and the height of the upper parts of the anchor bolts 3 exposed from the steel cage template 1 can also be very conveniently adjusted through the nuts 4; of course, the fixing process of the multiple anchor bolts 3 does not require welding, and will not damage the steel bars in the steel cage, so the work efficiency and safety performance are high.

[0063] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0064] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
