Method and device for jointing reinforcement and vibration readjustment construction of pre-embedded bolt

Abstract

The invention provides a method and a device for jointing reinforcement and vibration readjustment construction of a pre-embedded bolt, belonging to a civil engineering construction method. The method is characterized in that a fixed frame is installed outside a concrete foundation; the fixed frame is provided with a tuner and a crossed buckle; are connected with the pre-embedded bolt is extended by a jointing rod and a jointing sleeve in a spurious way; the tuner and the crossed buckle suspends the pre-embedded bolt in place and the foundation concrete is grouted; the exact positioning of the pre-embedded bolt is realized by the tuner and the vibration of the concrete, thus ensuring the installation precision of the pre-embedded bolt; and the method comprises the construction steps of 1 installing the fixed frame; 2. installing the jointing rod, the jointing sleeve, the tuner and the pre-embedded bolt; 3. aligning and adjusting the pre-embedded bolt primarily; 4. grouting the foundation concrete; and 5. aligning and adjusting the pre-embedded bolt secondarily. The device is safe and reliable for use, reduces the consumption and waste of the steel material, reduces the construction cost, and improves the installation precision and engineering quality of the pre-embedded bolt.

Description

technical field [0001] The invention belongs to a civil construction method, in particular to a construction method of pre-embedded bolts. Background technique [0002] At present, the construction method of pre-embedded bolts in concrete foundation is welding and fixing method. The support is fixed by section steel or steel bars in the foundation body, and the pre-embedded bolts are first welded and fixed together with the foundation steel bars and formwork supports, and then concrete is poured and formed at one time; this method exists Two major defects: first, each pre-embedded bolt must first be provided with an unshaped steel fixing frame inside and outside the foundation, and the steel cannot be recycled, resulting in a large amount of waste; The deviation is large, which affects the installation accuracy and engineering quality of the embedded bolts. Contents of the invention [0003] The purpose of the present invention is to propose a construction method and devi...
