Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Examples

The present embodiment provides a pin shaft connecting structure with a cover, as shown in fig. 1-3, including a connecting plate 120 and a connecting member 140, where the connecting plate 120 includes a fixed end 121 and a mounting end 122, the fixed end 121 is fixedly connected to the main body 110, the mounting end 122 is rotatably connected to the connecting member 140 through a pin 130, the first cover 150 covers the connecting plate 120 and is fixedly connected to the connecting plate 120, a gap is provided between the first cover 150 and the connecting member 140, and the second cover 170 covers a joint of the pin and is fixedly connected to the connecting member 140.

The body 110 is typically a beam, column, beam-column node, having greater rigidity and strength, and may be considered a rigid body in a pinned connection.

The connecting plate 120 is generally a thick plate, as shown in fig. 3, wherein the fixing end 121 can be appropriately changed in shape according to the structural form of the main body 110 so as to be inserted into the main body 110, such that the connecting plate 120 is completely fixed to the main body 110, and the shearing force of the pin 130 is transmitted to the main body 110, and the connecting plate 120 is welded to the main body 110 in this embodiment.

The end of the mounting end 122 is a circular arc, the radius of the circular arc can be adjusted according to the design strength of the pin shaft connection structure, and a connecting plate pin shaft hole 123 with a corresponding size is arranged. Wherein adjusting the widths of a and b and the overhang length c at the ends of the mounting end 122 can adjust the maximum rotational angle of the pintle connection.

As shown in fig. 4, the pin 130 connects the connecting plate 120 and the connecting member 140 together through the connecting plate pin hole 123 and the connecting member pin hole 142, and the specification of the pin 130 can be checked and selected according to the design load.

The connecting members 140 are generally diagonal rods or tie rods, and have a box-shaped cross section and a small number of I-shaped cross sections. In this embodiment, a box-shaped cross section is taken as an example, two side surfaces of the box body are extended to form two extending webs 141, and the two extending webs 141 are provided with connecting member pin holes 142.

The connecting member pin hole 142 is sized to conform to the outer diameter of the pin 130 and to ensure that the overhanging web 141 meets design strength.

The flange 143 of the connecting member 140 is disposed only at a position apart from the body 110 outside the pin joint, and the second cover 170 is used instead of the flange 143.

As shown in fig. 5, the thickness of the left and right ends of the pin joint is the same due to the existence of the first cover 150, so as to meet the requirement of building beauty.

The first cover 150 is completely separated from the connection member 140, and the size of the gap is precisely calculated so that the connection member 140 can rotate around the pin 130 by a small angle.

At the pin shaft connection position, a flitch 160 is arranged between the overhanging web 141 and the connecting plate 120, the flitch 160 is circular, free rotation of the pin shaft connection structure cannot be influenced, and the thickness of the flitch 160 can be adjusted to adapt to connection of the connecting plates 120 with different thicknesses and the pin shafts 130 with different specifications.

Through this round pin hub connection structure, the lid can cover round pin hub connection department and most connecting plate completely, only can see the lid from the outward appearance, and the surfacing, building is pleasing to the eye, can play well that the protection is inside round pin hub connection structure does not receive the harm, can also realize the small-angle free rotation of round pin hub connection department. The requirements of the appearance of the building and the structural function are considered.
