[0001] The utility model relates to the technical field of precast square piles, and particularly relates to an installation and positioning device for precast square piles. Background Art

[0002] Precast square piles are processed in factories and then transported to the construction site for construction. During the construction process of precast square piles, holes need to be formed first. The hole-forming process is the same as that of bored cast-in-place piles, both are round holes. During the process of lowering the precast square pile, the top of the pile is fixed by auxiliary tools to ensure that the pile position accuracy meets the requirements. However, due to the inability to position the bottom end of the pile, if not controlled properly, it is very easy to cause excessive installation accuracy deviations such as pile position and verticality after passing through the entire length of the pile foundation. Content of the Utility Model

[0020] In order to make the technical means, creative features, achieved objectives and functions of the utility model more clear and easy to understand, the technical solutions in the utility model will be further described below with reference to the drawings and embodiments.

[0021] Please refer to Figures 1 to 5As shown in the figure, a precast square pile installation positioning device includes: a first positioning plate 1, a second positioning plate 2, a first fixing bar 3 and a second fixing bar 4; a space for fitting the precast square pile is formed between the first positioning plate 1 and the second positioning plate 2. Both ends of the first fixing bar 3 are fixedly connected to the two relatively close sides of the first positioning plate 1 and the second positioning plate 2 respectively. Both ends of the second fixing bar 4 are fixedly connected to the two relatively close sides of the first positioning plate 1 and the second positioning plate 2 respectively. The first fixing bar 3 and the second fixing bar 4 are located between the first positioning plate 1 and the second positioning plate 2, and the first fixing bar 3 and the second fixing bar 4 are respectively located on the opposite sides of the precast square pile. A third fixing bar 5 is arranged on the first fixing bar 3 and the second fixing bar 4 and can extend into the perforations at the ends of the precast square pile. The outer sides of the first positioning plate 1 and the second positioning plate 2 are set as arc-shaped edges, and the arc-shaped edges are arranged to fit the inner wall of the drilling hole for installing the precast square pile.

[0022] As Figure 1 shown in the figure, in the middle is a precast square pile. There are perforations at the ends of the precast square pile. The perforation positions can use existing lifting through holes or PVC holes can be reserved in advance. By arranging the first fixing bar 3 and the second fixing bar 4, the first positioning plate 1 and the second positioning plate 2 are connected. The specific connection can be installed by welding or other existing methods. The third fixing bar 5 is arranged. Since the distance between the first fixing bar 3 and the second fixing bar 4 is fixed, when the two third fixing bars 5 are respectively welded and fixed to the first fixing bar 3 and the second fixing bar 4, the third fixing bar 5 is located in the perforations of the precast square pile, so that the first positioning plate 1 and the second positioning plate 2 are always in contact with the precast square pile; the first positioning plate 1 and the second positioning plate 2 are arranged. The inner parts of the first positioning plate 1 and the second positioning plate 2 are in contact with the precast square pile, and the outer parts of the first positioning plate 1 and the second positioning plate 2 are in contact with the inner wall of the drilling hole for installing the precast square pile, which fully locates and restricts the movement space of the precast square pile in the drilling hole and effectively improves the installation accuracy of the precast square pile.

[0023] Specifically, for the first embodiment of the present invention, it includes a first positioning plate 1 and a second positioning plate 2, as Figures 1 to 3As shown in the figure, horizontal sliding grooves 11 are provided on both sides of the precast square pile on the first positioning plate 1. One end of the first fixing bar 3 and the second fixing bar 4 are respectively slidably arranged in the two horizontal sliding grooves 11 in opposite directions. The two third fixing bars 5 are integrally formed with the first fixing bar 3 and the second fixing bar 4 respectively. Specifically, the length of the third fixing bar 5 is less than the length of the horizontal sliding groove 11. When installing the positioning device, first move the first fixing bar 3 and the second fixing bar 4 to the ends of the horizontal sliding groove 11 far from the precast square pile, and then make the first positioning plate 1 and the second positioning plate 2 fit the precast square pile to avoid the third fixing bar 5 blocking the fitting of the first positioning plate 1 to the precast square pile. Then move the first fixing bar 3 and the second fixing bar 4 so that the third fixing bar 5 is inserted into the perforation of the precast square pile. Finally, weld the two ends of the first fixing bar 3 and the second fixing bar 4 to their corresponding second positioning plates 2 respectively.

[0024] In the second embodiment of the present invention, it also includes a first positioning plate 1 and a second positioning plate 2, as Figure 4 shown. The difference is that perforations are provided on both the first fixing bar 3 and the second fixing bar 4. There is one third fixing bar 5, and the third fixing bar 5 is a round bar. The length of the third fixing bar 5 is greater than the distance between the first fixing bar 3 and the second fixing bar 4. One end of the third fixing bar 5 is fixedly connected to a plug 51, and the other end is externally provided with a thread. The threaded end of the third fixing bar 5 sequentially passes through the perforation of the first fixing bar 3, the perforation of the end of the precast square pile, and the perforation of the second fixing bar 4 and is threadedly connected to a nut 52. After the first positioning plate 1 and the second positioning plate 2 are installed and connected through the first fixing bar 3 and the second fixing bar 4, the first fixing bar 3, the second fixing bar 4 and the precast square pile are connected together through the third fixing bar 5, so as to install the positioning device on the precast square pile.

[0025] In the third embodiment of the present invention, it also includes a first positioning plate 1 and a second positioning plate 2, as Figure 5 shown. The difference is that both the first positioning plate 1 and the second positioning plate 2 include two sector blocks and a connecting plate fixed between the two sector blocks. It can reduce the weight of the device while also playing a role in positioning the precast square pile.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
