Steel structure connecting device

Abstract

The invention provides a steel structure connecting device used for connecting a sliding sleeve and a guide rod in a steel structure. According to the steel structure connecting device, the guide rod penetrates through the sliding sleeve and is connected with the sliding sleeve in a sliding mode; the steel structure connecting device comprises an insertion plate; the insertion plate penetrates through two first rectangular grooves formed in the sliding sleeve and two second rectangular grooves formed in the guide rod; the insertion plate is welded with the first rectangular grooves; and the length of each second rectangular groove along the axial direction of the sliding sleeve is larger than that of each first rectangular groove. The first rectangular grooves and second rectangular grooves with different lengths are formed in the sliding sleeve and the guide rod, and the insertion plate penetrates through the first rectangular grooves and second rectangular grooves, the sliding sleeve and the guide rod can synchronously rotate even if under high torque conditions; and meanwhile, because the length of each second rectangular grooves is larger than that of each first rectangular grooves, the insertion plate can move along the length direction of the second rectangular grooves, namely the insertion plate can relatively move between the sliding sleeve and the guide rod along the axial direction.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a connection device and method for a steel structure. Background technique [0002] At present, the curtain wall of the building is supported by a steel structure, which bears external forces such as weight, wind load, thermal expansion and contraction deformation, and earthquakes. There are various types of connection methods at the steel structure joints. In the past, the steel structure support joints of the curtain wall used the form of mutual welding of rods. The stress at the force is very large, and if no measures are taken, it will cause damage to the steel structure. [0003] In the prior art, the guide rod and the sliding sleeve are respectively connected to the steel structure. At this time, the guide rod and the sliding sleeve are nested together, and the horizontal sliding between the guide rod and the sliding sleeve is realized along the guide rod and the slidi...

There are various types of connection methods at the steel structure joints. In the past, the steel structure support joints of the curtain wall used the form of mutual welding of rods. The stress at the force is very large, if no measures are taken, it will cause damage to the steel structure

[0003] In the prior art, the guide rod and the sliding sleeve are respectively connected to the steel structure. At this time, the guide rod and the sliding sleeve are nested together, and the horizontal sliding between the guide rod and the sliding sleeve is realized along the guide rod and the sliding sleeve. The release of the axial stress, but sometimes, it is necessary to realize the synchronous rotation of the guide rod and the sliding sleeve along its axial direction. In order to achieve this effect, it can usually be achieved by connection means such as "spline", "key and keyway" Synchronous rotation, however, in the case of huge torque, the contact between the "spline" and "key and keyway" is a line contact, it is difficult to effectively achieve synchronous rotation, and the "spline" and "key and keyway" "The damage is also greater
