Description

Technical Field

[0001] This utility model relates to the field of steel structure installation technology, and in particular to a device for precise positioning of embedded parts in steel structure construction. Background Technology

[0002] In steel structure buildings, foundation embedded parts are crucial for achieving a rigid connection between the steel structure and the concrete foundation, ensuring effective load transfer and overall structural stability. The construction quality of these embedded parts is paramount to the stability and safety of the structure. However, traditional construction methods for anchor bolt positioning face numerous problems, including low labor efficiency, large positioning deviations, and difficulties in subsequent correction. Therefore, developing a device and method for efficient and precise positioning of embedded parts is of great significance. Utility Model Content

[0003] To solve the above problems, the present invention adopts the following technical solution.

[0004] A precision positioning device for embedded parts in steel structures includes a positioning steel plate, a steel pipe support, and a fixing nut, wherein the positioning steel plate has two forms: a square ring and a circular ring.

[0005] Furthermore, the positioning steel plate is placed on an independent steel pipe support, and anchor bolts are inserted through the reserved holes. The upper end is clamped and limited by double nuts, and the lower end is leveled by a single nut.

[0006] Furthermore, the reserved holes are evenly arranged on the positioning steel plate, and their diameter and number match the required anchor bolts.

[0007] Furthermore, the steel pipe support consists of a cross bracket and a vertical guide rod. The vertical guide rod has a stable base, and the cross bracket is horizontally fitted on the vertical guide rod and can move up and down to adjust the elevation of the positioning steel plate.

[0008] Furthermore, the anchor bolts are welded to the foundation reinforcement as a whole by positioning ribs, and two positioning ribs are set up to cross and close the weld to enhance the stability against vibration and tamping.

[0009] A method for precise positioning of embedded parts in steel structures includes the following steps: 1) Axis positioning and foundation verification: A total station is used to establish an axis control network. A polyethylene rope is stretched in the construction area to convert the virtual axis into a physical positioning line. The vertical guide rod of the steel pipe support is used as the axis mark.

[0010] 2) Positioning plate installation and bolt fixing: Place the positioning plate on the independent steel pipe support, insert the anchor bolts through the reserved holes, and clamp the upper and lower ends with double nuts for limiting and single nuts for leveling.

[0011] 3) Anchor bolts are welded to foundation reinforcement to form an integral frame, with upper and lower positioning reinforcements intersecting and welded to enhance vibration resistance and stability.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Through precise positioning, reliable fixing, scientific force transmission, and durable protection, a rigid connection between the steel structure and the concrete foundation is achieved, ensuring effective load transfer and overall structural stability. An independent support system and standardized molds are used to position and pre-embed anchor bolts. A total station and steel ruler are used for precise positioning, adjustment, and verification of the pre-embedded anchor bolts, controlling axial displacement within 3mm. The steel plate molds accurately fix the relative positions of the anchor bolts, ensuring the anchor bolts are firmly and reliably welded without loosening. The concrete column foundation is poured in one go, achieving the goal of accurate pre-embedding. This ensures both the high quality of the anchor bolt installation and the high quality of the steel structure construction and installation. Attached Figure Description
