Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of building component fixing, and particularly relates to a foundation bolt positioning and installing device. BACKGROUND

[0002] In recent years, with the rapid development of China's national economy, various types of steel structure buildings are increasingly favored by the majority of users, such as various types of steel structure workshops, large-span bridges and various steel net buildings. Compared with traditional reinforced concrete buildings, steel structure buildings have the characteristics of fast construction, small limitation and high recycling rate. With the wide application of steel structure buildings, the installation accuracy of steel support columns and foundation bolts of steel structure buildings has gradually become a key process in construction.

[0003] There are generally two ways to embed bolts in concrete foundations. The first way is straight embedding, which fixes the embedded foundation bolt on the steel reinforcement framework in the foundation first, pours the foundation concrete at one time, and forms the foundation bolt connecting the equipment. This method is prone to positional deviation during concrete pouring, and the embedded foundation bolt position often appears to be incorrect. The other way is post-embedding, which pours the foundation concrete in two times. When pouring the concrete for the first time, the bolt hole position of the embedded bolt is reserved first. After the first poured concrete is initially cured, the embedded bolt is inserted into the embedded bolt position, and then the second pouring of the concrete is carried out. This method is relatively accurate in positioning the embedded bolt, but the overall strength of the foundation is poor and cracks are prone to occur. Chinese invention patent CN202310237363.6, application date March 13, 2023, publication number CN116517310A, provides a positioning method for embedded foundation bolts of steel structure columns, which includes a rectangular frame made of a flat steel plate. The four corners of the rectangular frame are provided with foundation bolt through holes, and the embedded foundation bolts are inserted through the foundation bolt through holes. A lower locking nut is screwed on the embedded foundation bolt below the rectangular frame, and an upper locking nut is screwed on the embedded foundation bolt above the rectangular frame. See also documents CN202221081063.0 and CN202110659278.X, which can ensure the positioning of the foundation bolt during one-time concrete pouring construction.

[0004] The existing technology still has defects: 1) The precast hole design on the positioning frame / plate makes the device only applicable to foundations with one hole distance, so it can only be used on specified foundations or in specified projects, lacking adjustability; 2) The lower end of the bolt is welded to the foundation reinforcement, and the lower end does not strictly follow the hole distance requirement, making it difficult to vertically position the bolt rod in the foundation, and the bolt is prone to tilting, making it difficult to install the upper structure. SUMMARY
