[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] like Figure 1-4 As shown, the present application relates to an auxiliary device for positioning and installing steel bars for a pier body by a mold turning method, the auxiliary device for positioning and installing steel bars for a pier body by a mold turning method comprises: an auxiliary plate 1, steel bar positioning holes 2 opened on the auxiliary plate 1, the auxiliary plate 1 is preferably a metal auxiliary plate 1, so as to have sufficient strength to bear and fix the steel bars installed on the auxiliary plate 1; the steel bar positioning holes 2 are used to accurately position and fix the steel bars, and by pre-setting the positioning holes on the auxiliary plate 1, it can be ensured that the steel bars are accurately placed at the predetermined positions before pouring concrete, and the use of the auxiliary plate 1 with positioning holes can greatly improve the construction efficiency, and the construction personnel only need to insert the steel bars into the corresponding positioning holes to quickly complete the arrangement of the steel bars without measuring and locating the positions of the steel bars one by one, which not only reduces the construction time but also reduces the possibility of errors.

[0033] During the actual installation process, the steel bars of the previous section of the pier have been pre-buried and installed. After the pouring of the pedestal concrete is completed, the formwork of the first section of the pier can be directly supported. Once the concrete pouring of the first section of the pier is completed, the workers can quickly proceed with the installation of the steel bars of the second section of the pier.

[0034] The steel bar installation work of the second section pier is as follows: first, the semi-finished products processed in the steel bar factory are loaded and pulled to the site, and the steel bars are manually threaded according to the position of the steel bar positioning hole 2, and then the steel bars passing through the steel bar positioning hole 2 are connected and fixed with threading. After the steel bar is threaded, the auxiliary plate 1 and the threaded steel bars are hoisted as a whole, and each steel bar is manually adjusted up and down for threading connection. If the steel bar is offset or the threading is offset during hoisting and cannot be connected normally, only the lifting point needs to be adjusted to ensure the center position of the steel bar. That is to say, through this device, the steel bar installation work of the second section pier can be carried out while the concrete of the first section pier is solidified, and the auxiliary plate 1 and the steel bar positioning hole 2 can also be used to accurately position and install the steel bar, so that the steel bar installation of the second section pier can be completed in only one day, which greatly shortens the construction period and saves manpower and material resources; the accurate positioning of this device can directly reduce manual machinery and construction period, and because the position of the steel bar positioning hole 2 is pre-opened, only the steel bar needs to be threaded into the hole, so the spacing of the steel bars can also be effectively guaranteed.

[0035] After the steel bars of the pier column have been installed in accordance with the design requirements and construction specifications, in order to increase the stability of the pier column and prevent it from tilting or shifting due to wind or other external forces, it is necessary to set cables in four directions (usually east, south, west and north) at the top of the pier column to fix the pier column and disperse external forces. The other end of the cable needs to be fixed to the anchor on the ground, and the anchor must be set securely and reliably to ensure that the cable can play an effective role; in this embodiment, soft steel rope is preferably used as the material of the cable; the soft steel rope has a certain flexibility and strength, which can meet the requirements of force and durability. When the cable is subjected to tension, it must be able to meet the tension standards in the design requirements and construction specifications. If the tension of the cable is insufficient, it may cause it to break or fail, thereby affecting the stability of the pier column. After the cable is installed, it is necessary to use a tensioner to tighten the cable to ensure that it can play an effective role.

[0036] From the above description, it can be seen that in the embodiment of the present application, an auxiliary plate 1 is set and steel bar positioning holes 2 are opened around the auxiliary plate 1. Through the auxiliary plate 1 and the steel bar positioning holes 2 opened on the auxiliary plate 1, the purpose of accurately arranging the hole spacing and positioning the steel bars on the steel plate and then hoisting the whole is achieved, thereby achieving the technical effect of high installation accuracy, high efficiency and low cost, and further solving the technical problems of poor installation accuracy, low efficiency and high cost caused by the traditional method of using a crane to lift the steel bars and then manually connecting the steel bars one by one to the predetermined placement position for installation.

[0037] Preferably, the steel bar positioning holes 2 are evenly spaced apart on the outer edge of the auxiliary plate 1 so that the steel bars can be evenly installed.

[0038] Preferably, the auxiliary plate 1 is formed by splicing a plurality of plates of the same and / or different shapes. By splicing a plurality of plates of the same or different shapes, the space occupied by a single plate and the difficulty of processing can be reduced.

[0039] Preferably, the auxiliary plate 1 is a steel plate, which is processed on the basis of the existing steel plate, and the modification is simple and convenient, and the construction effect is obvious.

[0040] Preferably, the auxiliary plate 1 includes: a rectangular auxiliary plate 3, and a triangular auxiliary plate 4 vertically connected to the rectangular auxiliary plate 3; a right-angled side of the triangular auxiliary plate 4 is connected to a long side of the rectangular auxiliary plate 3, and the right-angled vertex of the triangular auxiliary plate 4 coincides with the vertex of the connected side of the rectangular auxiliary plate 3. When multiple groups of auxiliary plates 1 are required to be spliced, this connection method is used as the minimum connection unit, and then they are spliced ​​in pairs. By using this auxiliary equipment, steel bars can be processed in a centralized place and can be hoisted to the construction site as a whole, which greatly improves construction efficiency. Moreover, traditional pier construction requires additional supporting structures, but the present device does not require additional supporting structures during installation, thereby simplifying the construction process.

[0041] Preferably, the auxiliary plate 1 includes: two mutually perpendicular rectangular auxiliary plates 3, and a triangular auxiliary plate 4; the two right-angled sides of the triangular auxiliary plate 4 are respectively connected to the two long sides of the two rectangular auxiliary plates 3, and the right-angled vertex of the triangular auxiliary plate 4 coincides with a vertex of the rectangular auxiliary plate 3, forming a U-shape.

[0042] Preferably, a lifting piece is welded on the top of the auxiliary plate 1, and the lifting piece can be selected as a short angle iron, which is convenient for accurate positioning when the steel bars are hoisted and placed as a whole; an I-beam is welded on the top of the auxiliary plate 1, which can increase the rigidity and bearing capacity of the steel plate.

[0043] Preferably, at least two rows of steel bar positioning holes 2 are evenly arranged on each long side of the rectangular auxiliary plate 3, and at least one row of steel bar positioning holes 2 is evenly arranged on each short side of the rectangular auxiliary plate 3; the position and spacing of the steel bars are crucial to the overall strength and stability of the structure. By opening different numbers of positioning holes on each long side and short side, it is possible to adapt to the arrangement of steel bars of different specifications and requirements, so that the auxiliary plate 1 has higher versatility and flexibility, and can adapt to various construction scenes and needs; two or more rows of steel bar positioning holes 2 can arrange more steel bars in a limited space, thereby increasing the density of the steel bars and improving the overall strength and bearing capacity of the concrete structure.

[0044] Preferably, the spacing between the two rows of steel bar positioning holes 2 is different. By setting up multiple rows of steel bar positioning holes 2, it is possible to adapt to the requirements of steel bar arrangement with different spacings. The same auxiliary plate 1 can be used for steel bar arrangement of various specifications and requirements, thereby improving the versatility and use efficiency of the auxiliary plate 1. In actual construction, it may be necessary to adjust the position and quantity of the steel bars according to specific circumstances. Multiple rows of steel bar positioning holes 2 provide construction personnel with greater flexibility. Construction personnel can choose which positioning holes to use as needed to achieve the best construction effect.

[0045] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
