[0043] In order to be able to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

The embodiments described are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0044] It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature, or it may be indirectly fixed or connected to the other feature. In addition, the descriptions of up, down, left, right, etc. used in the present invention are merely relative to the relative positional relationships of the components of the present invention in the accompanying drawings. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0045] like Figure 1-7 As shown, a steel structure embedded bolt structure includes a positioning plate 100, and the positioning plate 100 is also provided with a plurality of positioning drill holes 110 for embedded parts to pass through. In this embodiment, the embedded parts used are set as bolts 210. A plurality of bolts 210 are installed in the positioning drill holes 110 respectively, and the bolts 210 are fixed to the positioning plate 100 through the fixing parts 400 to achieve the installation and fixation of the bolts 210. In this embodiment, a pier 300 is also provided, and the positioning plate 100 is placed on the pier 300 so that a certain distance is formed between the positioning plate 100 and the ground, which is convenient for drilling holes in the positioning plate 100 and installing bolts 210. There are two piers 300, which ensure that the positioning plate 100 can be placed on the pier 300 relatively stably to avoid the positioning plate 100 from tipping over during the drilling or installation of the bolts 210.

[0046] In this embodiment, one end of the bolt 210 fixedly connected to the positioning plate 100 is provided with an external thread 211, and the fixing member 400 used is a nut 410, which is threadedly connected to the external thread 211 of the bolt 210 to achieve the fixation of the bolt 210. The fixing method of adopting a threaded connection is simple to operate, convenient to construct, and the fixing member 400 is easy to obtain. A gasket 420 is also provided between the nut 410 and the positioning plate 100 to further ensure that the bolt 210 can be firmly installed and fixed on the positioning plate 100. Of course, on the basis of satisfying the fixed installation of the bolt 210 and the positioning plate 100, it can also be achieved through other structures and components, such as welding fixation, etc., and such fixed connection method designs all fall within the scope of protection of the present invention.

[0047] During the process of fixing the bolt 210 to the positioning plate 100, the positioning plate 100 is placed horizontally, and the verticality of the bolt 210 is adjusted using a vertical adjustment mechanism, so that the bolt 210 and the positioning plate 100 are arranged perpendicular to each other. This ensures that the bolt 210 can also maintain its verticality when it is subsequently installed on the base 500, improving the accuracy of the installation of the bolt 210 and providing a guarantee for the accurate installation of the subsequent steel structure column. In this embodiment, the vertical adjustment mechanism used is a hanging hammer, which has a simple structure, is easy to operate, and can achieve the effect of assisting in adjusting the verticality of the bolt 210.

[0048] After the embedded parts are fixedly connected to the positioning plate 100, the embedded parts are interconnected and fixed using a plurality of connecting steel bars 220, so that the embedded parts and the connecting steel bars 220 form a unified embedded part structure. In this embodiment, the embedded parts used are bolts 210, that is, the embedded part structure is a bolt structure 200. The connection and fixation of the connecting steel bars 220 can effectively ensure the stability of the bolts 210, preventing the bolts 210 from shifting during the subsequent pouring of concrete 700, thereby better ensuring the overall stability of the embedded bolt structure of the entire steel structure foundation.

[0049] like Figure 1-7 As shown, a construction method based on the above-mentioned steel structure embedded bolt structure includes the following steps:

[0050] S1. Take a positioning plate 100 and drill a plurality of positioning holes 110 through the positioning plate 100.

[0051] S2. Pass the embedded parts through the positioning holes 110 and fix them on the positioning plate 100;

[0052] S3, tie the bottom reinforcement of the cap 500;

[0053] S4: After the bottom reinforcement is tied, the bolts 210 are hoisted onto the bottom reinforcement of the cap 500;

[0054] S5. After the ribs 600 of the platform 500 are tied, the embedded parts are positioned at designated locations and fixedly connected to the ribs 600;

[0055] S6. Pour concrete 700 into the foundation 500.

[0056] Specifically, in this embodiment, the embedded parts used are bolts 210. In step S1, buttresses 300 are also provided, and the positioning plate 100 is placed on the buttresses 300, so that a certain distance is formed between the positioning plate 100 and the ground, which facilitates drilling holes in the positioning plate 100 and installing bolts 210. Two buttresses 300 are provided to ensure that the positioning plate 100 can be placed relatively stably on the buttresses 300 and prevent the positioning plate 100 from tipping over during drilling or installing bolts 210.

[0057] In step S2, the step of fixing the bolt 210 on the positioning plate 100 includes:

[0058] S21. One end of the bolt 210 is provided with an external thread 211. The end of the bolt 210 provided with the external thread 211 is passed through the positioning drill hole 110, and the bolt 210 is fixed to the positioning plate 100 by using a fixing member 400. In this embodiment, the fixing member 400 used is a nut 410, which is threadedly connected to the external thread 211 of the bolt 210 to achieve the fixation of the bolt 210. The fixing method of adopting a threaded connection is simple to operate, convenient to construct, and the fixing member 400 is easy to obtain. A gasket 420 is also provided between the nut 410 and the positioning plate 100 to further ensure that the bolt 210 can be firmly installed and fixed on the positioning plate 100. Of course, on the basis of satisfying the fixed installation of the bolt 210 and the positioning plate 100, it can also be achieved by other structures and components, such as welding fixation, etc. Such fixed connection method designs all fall within the protection scope of the present invention.

[0059] S22. When the bolt 210 is fixedly connected to the positioning plate 100, the positioning plate 100 is placed horizontally, and the vertical adjustment mechanism is used to adjust the verticality of the bolt 210 so that the bolt 210 and the positioning plate 100 are perpendicular to each other. This ensures that the bolt 210 can also maintain its verticality when it is subsequently installed on the base 500, improving the accuracy of the installation of the bolt 210 and providing a guarantee for the accurate installation of the subsequent steel structure column. In this embodiment, the vertical adjustment mechanism used is a hanging hammer, which has a simple structure, is easy to operate, and can achieve the effect of assisting in adjusting the verticality of the bolt 210.

[0060] S23. Connect and secure the embedded parts to each other using a plurality of connecting steel bars 220. The connecting steel bars 220 and the embedded parts form an integrated embedded part structure. In this embodiment, since the embedded parts are bolts, the embedded part structure is a bolt structure 200. The connection and securing of the connecting steel bars 220 effectively ensures the stability of the bolts 210, preventing the bolts 210 from shifting during the subsequent pouring of concrete 700, thereby better ensuring the overall stability of the embedded bolt structure of the entire steel structure foundation.

[0061] In step S4, the step of placing the bolt 210 on the platform 500 includes:

[0062] S41. Remove the positioning plate 100, and then hoist the bolt structure 200 after removing the positioning plate 100 onto the bottom steel bar, and adjust the direction of the bolt structure 200 according to the corresponding construction requirements so that the bolt structure 200 can be smoothly installed on the base. Removing the positioning plate 100 can effectively reduce the overall weight and facilitate the lifting of the bolt structure 200 onto the base 500. In this process, the entire bolt structure 200 is made separately, has good integrity, can be processed at any time, has a fast construction speed, is not restricted by the site, and does not need to be affected by the construction steps and progress on the base 500. It can be quickly installed after being tied with the bottom steel bar of the base 500, which does not affect the construction period and is conducive to speeding up the construction period.

[0063] In step S5, the steps of fixing the bolt 210 to the gluten 600 include:

[0064] S51. After the bolt structure 200 is positioned at the specified position, the positioning plate 100 and the fixing member 400 are used to fix the bolt structure 200 again, which can further effectively ensure the stability of the bolt structure 200 and prevent the bolt 210 from being offset during the subsequent pouring of concrete 700, thereby better ensuring the overall stability of the embedded bolt structure of the entire steel structure foundation and the accuracy of the positioning of the bolt 210.

[0065] S52. Weld the ribs 600 to the positioning plate 100. The bolt structure 200 is fixed to the ribs 600 on the base 500 via the positioning plate 100. This can further improve the stability of the bolt structure 200 and further avoid the displacement of the bolts 210 during the subsequent pouring of concrete 700.

[0066] In step S6, after the concrete 700 is poured, the bolt structure 200 is fixed and stable. At this time, the positioning plate 100 and the fixing part 400 can be removed and reused to avoid the waste of the positioning plate 100, which is conducive to the recycling of resources and the reduction of construction costs. In addition, the reused positioning plate 100 eliminates the construction step of re-drilling, which is conducive to improving construction efficiency.

[0067] While the preferred embodiments of the present invention have been described in detail above, it should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the prior art should be within the scope of protection defined by the present claims.
