Beneficial effect

In order to solve the shortcomings of the construction of the external wall panel of the steel structure, the inventor found after repeated research that the dynamic and static steel structure connector in the embodiment was proposed, in which:

The strength of the end connector is adjustable: according to the structural design, adjusting the height of the end trapezoidal support steel plate to increase the welding area, or increasing the number of support steel plates, can adjust the strength of the end connector to meet the mechanical requirements of the steel structure.

The sliding connector is beneficial to handle the installation error caused by the steel beam not straight: After the lower end of the steel beam is connected, the error of the steel beam will be reflected on the upper end of the steel beam. Since the upper connector is sliding, there are sliding long holes, which can effectively handle this error. Of course, we must first select qualified steel beam products.

Structure and principle of dynamic and static steel structure connector

As a standard layer connector, this is the core component that connects steel pillars and steel beams. Therefore, it must be firm, easy to install, and not too bulky. See Figure 1. The main components of the dynamic and static steel structure connectors are: through-body mandrel, sliding connector, and static connector.

The through-body mandrel can be made of thick square steel. It consists of a lower insertion shaft head, a static connector section, a sliding connector section, and an upper insertion shaft head. The sliding connector and the static connector are connected into one body, and inserted into the lower steel pillar and the upper steel pillar, which ensures the accurate and stable force transmission of the steel structure.

Static connector section: The through-mandrel is connected to the static connector by welding, and the vertical welding is used for welding, which is conducive to dispersing the force of the through-mandrel and makes the connection between the through-mandrel and the static connector closer.

Sliding connector section: The through-mandrel and the sliding connector are bolted horizontally to provide auxiliary force to stabilize the sliding connector.

Inserting the upper shaft head: The upper shaft head of the through-mandrel is inserted into the upper steel column, and the screw is used to horizontally connect the upper steel column to ensure that the sliding connector sleeve is in accurate contact with the upper steel column bearing surface without shifting.

Lower shaft head: The lower shaft head of the mandrel is inserted into the lower steel column, and the screw is used to horizontally connect with the lower steel column to ensure that the static connector sleeve is in accurate contact with the bearing surface of the lower steel column without offset.

The sliding connector is composed of an uploading force sleeve, an upper end connector of a steel beam, and a reinforced fastening bolt. Uploading force sleeve structure: The uploading force sleeve is made of square steel with the same specifications as the transmitting force sleeve, and is welded to the through shaft and the lower connector. Uploading force sleeve function: accept the resultant force from the upper end connector and the upper steel pillar, and transmit this resultant force to the downward force sleeve. Upper end connector structure: It consists of end overlap steel plate, trapezoidal support steel plate, strong, anti-loose fastening bolts. The role of the upper end connector: to bear the resultant force generated by the upper end of the steel beam. The resultant force at the upper end of the steel beam comes from the 4 connecting bolts. Therefore, the four bolts of the upper end connector are required to be reinforced and anti-loose fastening bolts.

The static connector is composed of a lower force transmission sleeve and a lower steel beam end connector. Down force transmission sleeve structure: The force transmission sleeve is made of square steel with the same specifications as the steel column below, and is welded to the through shaft and the lower connector. Downward force sleeve function: Accept the resultant force from the lower end connector, sliding connector, and the upper steel pillar, and transmit this resultant force to the lower steel pillar. Lower end connector structure: It consists of end overlap steel plate and trapezoidal support steel plate. The role of the lower end connector: to bear the resultant force generated by the lower end of the steel beam. In the case of failure of the upper end bolt, the resultant force at the lower end of the steel beam is almost the force at the end of the steel beam. Therefore, the thickness of the overlap steel plate and the trapezoidal support steel plate must be sufficient, and the welding area must be sufficient.

Force transfer of static and dynamic steel structures

Steel structure force transmission: upload force sleeve transmission force: Accept the combined force of the upper steel pillar and the upper end connector of the steel beam, and transmit the force to the lower force transmission sleeve. Therefore, it is required that the contact surface of the square steel of the upper and lower force sleeves be made uniformly and well. Down force transmission sleeve: The combined force of the up force sleeve and the lower end connector of the steel beam is transmitted to the steel pillar below. Therefore, it is required that the contact surface between the square steel of the lower force sleeve and the steel pillar below be made uniform. Good bit.
