Description

Technical Field

[0001] The utility model relates to the technical field of anchor bolts, in particular to an anchor bolt fixing structure. Background Art

[0002] During the construction process, compared with traditional reinforced concrete buildings, steel structure buildings using bolts are more common and require greater precision. Currently, many industrial buildings have many large or small anchor bolts for the installation of equipment or connectors. When the anchor bolts are installed on the concrete foundation, the embedded part of the bolts is buried in the concrete. When the concrete solidifies, the exposed end is used to connect objects.

[0003] The anchor bolts on the market have a simple structure during use. When embedded, they are prone to sinking and displacement due to the small bottom area, and the overall stability is not strong. Deviations in the embedding process of the anchor bolts will directly affect the installation of the main steel structure and the safety of the building; and the protection is poor and the anti-rust effect is not good, which brings troubles to people's use; in addition, when pouring concrete, the impact force of the concrete leakage and the vibration generated when the concrete vibrator contacts the steel bars or iron parts often cause the embedded anchor bolts to have a large displacement after the concrete is formed, resulting in the fixing accuracy of the anchor bolts cannot meet the installation requirements. In order to solve the above problems, we designed an anchor bolt fixing structure. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] Through the function of the mounting plate, threaded rod and clamping plate, two anchor bolts can be fixed at the same time, which can avoid deviation of the anchor bolts during the pre-embedding process, affecting the installation of the main steel structure and the safety of the building; concrete is poured through grouting in the pouring box, and the base plate is installed around the pouring through the fixing holes to prevent vibration during pouring from causing large displacement of the pre-embedded anchor bolts after the concrete is formed, resulting in the fixing accuracy failing to meet the installation requirements, and this fixed structure can be reused to reduce material waste.
