Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, and particularly relates to a positioning device suitable for accurately installing the steel bar framework of a square pier column. Background Technique
[0002] At present, for the construction of bridge pier columns, in order to improve the construction efficiency, a streamlined construction process of "field binding + on-site hoisting" of the steel bar framework is adopted. In the steel bar yard, the main steel bars and stirrups are assembled and formed into an integral steel bar framework through a steel bar binding jig, transported to the site, and the steel bar framework is inserted into the steel bar framework of the bearing platform by a crane, and then concrete pouring operation is carried out. This process simplifies the construction procedures and greatly improves the construction efficiency compared with a series of procedures such as pre-burying the main steel bars before the bearing platform is poured, erecting a platform on the bearing platform, and installing stirrups at high altitude in the traditional process. However, the following problems exist in the actual pre-insertion construction process of the pier column steel bar framework:
[0003] 1. When the steel bar framework is lofted and measured, the lofting base surface is the steel bar framework of the bearing platform, and the steel bars are in a grid shape. Sometimes the positioning points will fall on the steel bar grid, and the lofting points cannot be effectively marked.
[0004] 2. The current positioning process is to locate the four corner points of the pier column, and after temporary marking, connect each positioning point with a red line to pull out the side line of the pier column, and then use a ruler to deduct the protective layer thickness to obtain the positioning position of the pier column stirrups. The process is cumbersome and prone to errors, resulting in low positioning accuracy.
[0005] 3. After the lofting position is determined, the steel bar framework is hoisted. The positioning line cannot effectively limit the steel bar framework. Once the steel bar framework is misaligned during the falling process, it is difficult for humans to adjust, and it is necessary to recheck the positioning. Content of the Utility Model
[0006] In order to solve the above problems, the utility model discloses a positioning device suitable for accurately installing the steel bar framework of a square pier column, which has a delicate structure, simple procedures, is easy to operate and control, can adapt to the steel bar positioning of pier columns of different sizes, has high accuracy, can be reused, and reduces costs.
[0007] To achieve the above object, the technical solution of the utility model is as follows:
[0008] A positioning device suitable for accurately installing the steel bar framework of a square pier column includes a steel plate and a connecting rod structure;
[0009] The four steel plates are rigidly connected to four connecting rods to form a square working frame. The steel plates are of L-shaped structure. The four steel plates are arranged at the four corners of the working frame. The connecting rods are arranged between two adjacent steel plates. Each connecting rod is formed by sleeving a large pipe and a small pipe. Scale lines are provided on the connecting rods, and positioning marks are provided at the same position of each steel plate.
[0010] As an improvement of the utility model, the inner corner of the steel plate is a square limit clamping groove, and the length of the limit clamping groove is greater than the radius of the stirrup bending.
[0011] As an improvement of the utility model, the positioning marks are laser engraved and coated with bright colors.
[0012] The beneficial effects of the utility model are as follows:
[0013] 1. The four steel plates are rigidly connected into a whole by sleeves. Originally, it was necessary to measure the positioning points of the four steel plates. After being connected by the connecting rods, only the positions of two diagonal points need to be measured, saving the number of manual measurements and improving the construction efficiency.
[0014] 2. The stirrups originally located on the top surface of the pile cap skeleton are not installed in the back field. After arriving at the site, they are directly welded to the top of the pile cap as positioning steel bars through the positioning clamping grooves. The notch plays a limiting role on the in-place stirrups. While simplifying the operation, it ensures the construction of the subsequent integral pre-insertion process of the pier column, improves the precision of the steel bar pre-insertion, and avoids human errors.
[0015] 3. The connecting rod is a telescopic device. By stretching the connecting rod, it can be used for the pre-insertion construction of square piers with different sizes, achieving repeated use and reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following further clarifies the utility model in conjunction with the drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the utility model and not to limit the scope of the utility model.
[0021] As shown in the figure, a positioning device suitable for the precise installation of the steel bar skeleton of a square pier column described in the utility model includes a steel plate 1 and a connecting rod 2.
[0022] The four steel plates 1 are rigidly connected to four connecting rods 2 to form a square working frame. The steel plates are of L-shaped structure. There is a square limit slot 101 inside the steel plate 1. There is a positioning mark 102 on the steel plate 1. Each connecting rod 2 is formed by sleeving a large tube and a small tube. There is a scale line on the connecting rod 2. The connecting rod 2 can be telescoped according to the cross-sectional size of the pier column.
[0023] A locking bolt is provided at the sleeved part of the large and small tubes, which can lock conveniently after adjusting the length for steel bar skeletons of different sizes to prevent errors.
[0024] The overall working frame is square. The steel plates 1 are arranged at the four corners. The rigid connecting rods 2 are arranged between two adjacent steel plates 1. The connecting rod 2 and the steel plate 1 are rigidly connected.
[0025] A square limit slot 101 is arranged at the inner corner of the steel plate 1. The length of the limit slot 101 of the steel plate 1 is greater than the radius of the bend of the stirrup. As Figure 2 shown, the limit slot 101 can be fitted with the bend of the stirrup to limit the movement of the straight sections on both sides of the stirrup bend.
[0026] The four connecting rods 2 can be telescopically adjusted freely. The scale line provided on the connecting rod 2 can quickly read out the distance between the positioning marks 102.
[0027] The steel plate 1 is provided with positioning marks 102. The distance between the positioning points represents the outer dimension of the square pier column. The distance between the positioning points can be adjusted according to different pier column sizes.
[0028] The positioning marks 102 are at a position closer to the inner side of the iron plate 1, which is convenient for setting up the instrument during measurement and layout (it cannot be at the corner tip, otherwise the equipment vertical rod is likely to slip when leaning against here).
[0029] The positioning marks 102 are laser engraved and painted with bright colors.
[0030] It should be noted that the above content only illustrates the technical idea of the present invention and cannot be used to limit the protection scope of the present invention. For those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches all fall within the protection scope of the claims of the present invention.
