Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to an anchor bolt positioning device. Background Technology

[0002] Angle steel towers are tower structures primarily composed of long, vertically angled steel bars, with the tower body fixed to a pile foundation via base plates and bolts. In power transmission applications, tower leg reinforcement devices, through adjustable support structures forming pile foundations, can increase compressive strength by over 30% and tensile strength by 25%. This structure accounts for 68% of applications in power transmission lines and similar scenarios.

[0003] The pile foundation of angle steel towers typically uses bored cast-in-place piles with a pile diameter of 800mm to 1200mm and four pre-embedded anchor bolts of M30 to M64 specifications. For example... Figure 1 As shown, during construction, steel casing 6 is installed according to the design elevation of the pile top (the distance between the ground surface 8 and the top surface of the pile 7). The function of steel casing 6 is to position, protect the borehole opening, prevent ground stones from falling into the hole, prevent borehole collapse and backflow of sediment during drilling, and also serve as the basis for controlling the pile top elevation.

[0004] The existing method for pre-embedded anchor bolts involves installing a reinforcing cage on a steel casing and welding the anchor bolts to the cage. This method has the following disadvantages:

[0005] (a) Low construction efficiency;

[0006] (ii) The anchor bolts have no fixed support points on the steel cage. If the anchor bolts are misaligned, the handling is quite complicated. Utility Model Content

[0007] The purpose of this utility model is to provide an anchor bolt positioning device to effectively limit the installation position of the anchor bolts of the pre-embedded angle steel tower, thereby achieving high-quality and efficient construction.

[0008] The technical solution of this utility model is: an anchor bolt positioning device, including a clamping mechanism, a cross beam and a limiting plate. Each end of the cross beam is provided with the clamping mechanism. When two clamping mechanisms on the same straight line move closer to each other, they can form a clamping force or move away from each other to release the clamping force. The cross beam is provided with a vertically penetrating slide, and the limiting plate is placed on the slide. The limiting plate is provided with a first mounting hole for positioning the anchor bolt.

[0009] Preferably, the clamping mechanism includes a screw, a mounting block, and an abutment block. The mounting block is fixed to the lower surface of the cross beam, the screw is threaded onto the mounting block, and the ends of the screws on the four clamping mechanisms that are close to each other are connected to the abutment blocks.

[0010] Preferably, the end of the screw away from the abutment block is provided with a handle.

[0011] Preferably, the limiting piece includes a top plate and side plates vertically connected to both ends of the top plate, the two side plates are adapted to the inner wall surface of the slide, and the first mounting hole is provided on the top plate.

[0012] Preferably, the top plate is provided with a second mounting hole, and the upper end of the side wall of the cross beam forming the slide is provided with a plurality of third mounting holes, the second mounting hole being aligned with the third mounting hole therein and connected by a connector.

[0013] Compared with related technologies, the beneficial effects of this utility model are as follows:

[0014] I. This utility model has the function of adjusting and fixing the plane position and elevation of the anchor bolts. When constructing anchor bolts for pre-embedded angle steel towers, it enables the anchor bolts to be quickly and accurately positioned, which significantly improves the speed and construction quality of pre-embedded anchor bolts.

[0015] II. Compared with previous construction methods, the use of this device to pre-embed anchor bolts has the advantages of convenient construction operation, faster construction speed, and improved construction quality.

[0016] Third, this utility model is applicable to anchor bolts of various pile diameters and specifications ranging from 800mm to 1200mm, and can be reused, thus having a wide range of applicability;

[0017] IV. This utility model optimizes and improves the traditional operating process, making on-site operation simple; the clamping mechanism is adjustable and suitable for various pile diameters; the position of the limiting shim is adjustable and fixed with the cross beam.

[0035] S4. According to the design requirements of the anchor bolt 5 in the pile 7, adjust the position of the limiting piece 3, align the second mounting hole 34 with the corresponding third mounting hole 22, and then use a reinforcing bar (such as a Φ8 short steel bar) to insert into the aligned two holes to limit the position of the limiting piece 3.

[0036] S5, insert the anchor bolt 5 into the first mounting hole 33, adjust the top of the anchor bolt 5 to the designed position, and then tighten the nut 4 to fix it, thereby realizing the positioning and elevation setting of the anchor bolt 5;
