[0020] The following is combined with Figure 1 -Attached Figure 3 The present invention is described in further detail.

[0021] The embodiment of the present invention discloses a device and method for positioning and installing a bolt anchor box for a large equipment foundation. Figure 1 and Figure 2 The large equipment foundation bolt anchor box positioning installation device is used to fix multiple bolt anchor boxes 1, and the bottom of the bolt anchor box 1 is fixed with an anchor box leg 10. The installation device includes a positioning frame 2 used in pairs. In this embodiment, two pairs of parallel positioning frames 2 are taken as an example. The positioning frame 2 is made of 100mm*100mm square steel pipe.

[0022] Reference Figure 1 and Figure 2 The positioning frame 2 includes a horizontally arranged support rod 20, and a frame leg 21 is fixedly connected to the bottom of each end of the support rod 20 in an oblique manner, and two frame legs 21 are fixedly connected to the bottom of the middle of the support rod 20 in a vertical manner. The bottom end of the frame leg 21 is welded and fixed to the positioning rib embedded in the cushion layer, and the adjacent two obliquely arranged frames 21 at the same end are arranged in an eight-shaped shape. The adjacent two support rods 20 can be welded and fixed by means of a rib to enhance the overall structural strength. The positioning frame 2 is maintained in an upright state by the obliquely arranged frames 21 and the vertically arranged frames 21 cooperating with each other.

[0023] Reference Figure 1 and Figure 2 A plurality of steel bar cages 3 arranged in a straight line are vertically pre-embedded on the cushion layer. The steel bar cages 3 are located in the middle of the two pairs of positioning frames 2 to avoid the steel bar dense area and the bolt anchor box 1. The steel bar cages 3 serve as the concrete pouring entrance and the vibrating rod insertion point to reduce the impact on the installation accuracy of the bolt anchor box 1 during concrete pouring and vibrating.

[0024] Reference Figure 3 The method for positioning and installing a bolt anchor box for a large equipment foundation according to an embodiment of the present invention comprises the following steps: S1. Positioning and laying out the lines and installing the positioning ribs, specifically including: positioning and laying out the lines on the equipment foundation cushion layer by means of instruments, followed by drilling holes and implanting the positioning ribs to ensure accurate positioning when the positioning frame 2 is installed later.

[0025] S2. The bolt anchor box 1 is welded and fixed to the anchor box leg 10, specifically including: first inspecting the bolt anchor box 1 and the anchor box leg 10, checking their material certification documents, test reports and appearance quality, welding the bolt anchor box 1 and the anchor box leg 10 after confirmation, and checking the overall height and levelness after welding.

[0026] S3, the positioning frame 2 is welded and fixed to the positioning reinforcement, specifically including: while the reinforcement is tied, the positioning frame 2 is placed on the cushion layer, the frame legs 21 are inserted or clamped onto the positioning reinforcement and welded and fixed to the positioning reinforcement, ensuring that the horizontal deviation of the positioning frame 2 is ≤2mm and the elevation deviation is ≤1mm.

[0027] S4, the bolt anchor box 1 is welded and fixed to the positioning frame 2, specifically including: positioning and marking on the support rod 20 of the positioning frame 2, hoisting each bolt anchor box 1 as a whole to the corresponding position, and welding and fixing the bolt anchor box 1 to the support rod 20 after determining the elevation and horizontal position of the bolt anchor box 1, and subsequently welding reinforcement bars to enhance the overall structural strength.

[0028] S5, installing the steel bar round cage 3, specifically including: pre-embedding a number of steel bar round cages 3 on the cushion layer, paying attention to avoiding the steel bar dense area and the position of the bolt anchor box 1.

[0029] S6, concrete pouring and vibrating, specifically including: pumping concrete into the steel cage 3, according to the layered pouring mode, the concrete diffuses to the surroundings through the gaps on the steel cage 3, thereby reducing the influence of the concrete pouring process on the installation accuracy of the bolt anchor box 1; inserting a vibrating rod into the steel cage 3 to vibrate the concrete, so as to avoid the influence of the concrete vibration process on the installation accuracy of the bolt anchor box 1.

[0030] S7. Overall inspection, including: inspection of the initial axis, diagonal, elevation and reinforcement conditions, and reporting for inspection after passing the self-inspection.

[0031] Compared with the positioning and installation process of the traditional bolt anchor box 1, the present invention adopts a positioning frame 2 as the overall support and positioning structure of the bolt anchor box 1. The elevation and horizontal position of the bolt anchor box 1 can be conveniently adjusted and positioned on the positioning frame 2, and the controllability is significantly improved. At the same time, the positioning frame 2 is welded and fixed to the positioning ribs, which ensures the stability of the positioning frame 2, and thus also ensures the stability of the bolt anchor box 1.

[0032] The anchor box legs 10 can be cast in concrete as anchors, improving the overall pull-out resistance of the bolt anchor box 1. The elevation adjustment of the bolt anchor box 1 no longer relies on the anchor box legs 10. Even if the cushion layer is laid unevenly, causing the bottom end of the anchor box legs 10 to be suspended, it will not affect the accurate positioning and position fixation of the bolt anchor box 1. The positioning and installation device and method not only improve the installation accuracy of the bolt anchor box 1, but also improve the construction efficiency, avoid rework due to installation accuracy problems, and also help reduce labor costs and production costs.

[0033] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
