Description

CROSS REFERENCE TO RELATED APPLICATION

This application claims priority to Chinese Patent Application No. 202310856029.9, titled “RELIABLE CONNECTION STRUCTURE FOR BOLT AND PRE-BURIED PLATE” and filed to the China National Intellectual Property Administration on Jul. 12, 2023, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to the field of connection of building components, and more particularly, to a reliable connection structure for a bolt and a pre-buried plate.

BACKGROUND

Components that need to be fixed are connected and fixed to concrete of supporting parts through anchor bolts. Due to uneven technical levels of on-site construction, accuracy of construction results cannot be guaranteed. The components that need to be fixed are connected by means of foundation pads. Reference is made to the Chinese patent application number 201610232102.5, bottom surfaces of the foundation pads are connected to first bolts pre-buried in foundations, and top surfaces of the foundation pads are connected to second bolts on the bottom surfaces. The above connection manners require higher positioning accuracy for the anchor bolts/pre-buried bolts, but during the process of pouring the concrete, the anchor bolts/bolts are prone to vibration and impact, causing a decrease in positioning accuracy, which greatly has a negative effect on assembly quality. Traditional steel structures are pre-buried and bottom plates with anchor bars are pre-buried, where the components that need to be fixed are directly welded to pre-buried plates. The directly welded components cannot be repaired, and complex angle positions cannot be welded. The traditional steel structures are pre-buried and the bottom plates with the anchor bars are pre-buried, and then connecting plates with studs are welded. The components that need to be fixed are subjected to bolted connection with the studs by means of internal high-strength hexagonal head nuts. However, high-temperature welding between the bolts and steel adversely affects strength of the bolts, which may lead to fracture of the bolts. Therefore, adoption of this implementation solution may pose a safety hazard.

SUMMARY

The present disclosure provides a reliable connection structure for a bolt and a pre-buried plate, aiming to solve a problem of poor reliability in connection between the bolt and the pre-buried plate.

Embodiments of the present disclosure provide a reliable connection structure for a bolt and a pre-buried plate, including a component, where a bolt through hole is provided on the component. An upper connecting plate comes into contact with the component, a lower connecting plate is welded to the upper connecting plate, a pre-buried plate is welded to the lower connecting plate, and a high-strength hexagonal head bolt comes into contact with the pre-buried plate. The high-strength hexagonal head bolt is slidably connected to the lower connecting plate, the high-strength hexagonal head bolt is slidably connected to the upper connecting plate, and the high-strength hexagonal head bolt is slidably connected to the bolt through hole. An outer side of the high-strength hexagonal head bolt is connected to a high-strength hexagonal head nut through a screw thread, and the high-strength hexagonal head nut comes into contact with a gasket.

In the reliable connection structure for the bolt and the pre-buried plate of the present disclosure, a bolt through groove is provided on the upper connecting plate, and the high-strength hexagonal head bolt is slidably connected to inside of the bolt through groove. By designing the bolt through groove, the high-strength hexagonal head bolt can thread through the upper connecting plate to slide.

In the reliable connection structure for the bolt and the pre-buried plate of the present disclosure, number of the bolt through grooves is three, and the three bolt through grooves are unevenly distributed on the upper connecting plate. The three bolt through grooves may be designed for threading and positioning of the three high-strength hexagonal head bolts.

In the reliable connection structure for the bolt and the pre-buried plate of the present disclosure, a bolt head self-locking card slot is provided on the lower connecting plate, and the high-strength hexagonal head bolt is slidably connected to inside of the bolt head self-locking card slot. By designing the bolt head self-locking card slot, the high-strength hexagonal head bolt can thread through the lower connecting plate to slide.

In the reliable connection structure for the bolt and the pre-buried plate of the present disclosure, number of the bolt head self-locking card slots is three, and the three bolt head self-locking card slots are unevenly distributed on the lower connecting plate. The three bolt head self-locking card slots may be designed for threading and positioning of the three high-strength hexagonal head bolts.

In the reliable connection structure for the bolt and the pre-buried plate of the present disclosure, the gasket is slidably connected to the high-strength hexagonal head bolt, and the gasket comes into contact with the component. By designing the gasket, a contact area and a friction force between the high-strength hexagonal head bolts can be increased, and stability of high-strength hexagonal head bolts can be improved.

The technical solutions provided in the embodiments of the present disclosure may include the following beneficial effects. The reliable connection structure for the bolt and the pre-buried plate is designed in the present disclosure. By designing the high-strength hexagonal head bolt to fit with the high-strength hexagonal head nut and the gasket, a fixed connection between the upper connecting plate, the lower connecting plate, and the component is achieved. An objective of fixing the component to the pre-buried plate is achieved by welding the lower connecting plate to the pre-buried plate. By means of the bolt head self-locking card slot provided on the lower connecting plate, the high-strength hexagonal head bolt can be limited, which can prevent the high-strength hexagonal head bolt from rotating in the lower connecting plate, thereby improving reliability of the connection between the high-strength hexagonal head bolt and the pre-buried plate.
