Description

A multi-bar pin shaft connection node

technical field

The invention relates to the field of civil structure engineering, in particular to a joint form in which multiple steel components are hinged and connected at the same point.

Background technique

The pin connection can realize the ideal hinged connection between steel structure members, and can well express the logic and beauty of the structure, and is often used in the design of exposed steel structures. However, the conventional pin joint is only suitable for the connection between two rods. When multiple rods are required to be hinged at one point, it is very difficult to adopt this connection method because the arrangement of the pin shaft and the ear plate is limited. . Therefore, a new pin joint is needed to meet the requirements of multi-member intersection.

Contents of the invention

In order to overcome the defect of conventional pin shaft joints, the main purpose of the present invention is to provide a multi-bar intersection joint construction form with reasonable structure, safety and reliability, beautiful appearance and convenient construction.

In order to solve the above technical problems, the basic technical solution adopted by the present invention is: a multi-rod pin shaft connection node, two main rods and several secondary rods intersect at the same point, and the ends of the main rods are provided with The ear plate of the main rod end with a hole, the end of the secondary rod is provided with a secondary rod end ear plate with a hole, and the two main rods are hinged by the kingpin shaft; the two ends of the kingpin shaft Each lug on the shaft with a hole, the size of the hole on the lug on the shaft and the lug on the secondary rod end match each other, and the several secondary rods pass through the secondary pin shaft and the shaft on the shaft respectively. The lugs are hinged.

In the above scheme, all lugs at the end of the main rod, lugs at the end of the secondary rod and lugs on the shaft can be made of steel castings or common steel plates, and the connections between the main rods and the secondary rods can be welded or bolted. The lug plate on the shaft can be welded into one with the kingpin shaft, and can also be processed integrally with the kingpin shaft. the

Based on the above basic technical solution, when the number of secondary rods is two, the technical solution is: the first main rod, the second main rod, the first primary rod, and the second secondary rod intersect at the same point, so The ends of the first main rod and the second main rod are respectively provided with the first main rod end ear plate and the second main rod end ear plate, and the ends of the first rod and the second rod are respectively provided with There are first rod end lugs and second rod end lugs, and the kingpin shaft passes through the first main rod end lugs and the second main rod end lugs to connect the first main rod part with the second main rod The two ends of the main pin shaft are hinged with lugs on the shaft, and the first rod and the second rod are hinged to the lugs on the shaft through the first pin and the first pin respectively. Thus forming a node where multiple rods are hinged at one point.

This node is suitable for the connection between multi-bars hinged at one point, which can fully express the logic of the structure, and its main components can be processed and manufactured in the factory. During on-site installation, only the pin shaft needs to be fixed to ensure the mechanical performance. And appearance quality can be effectively guaranteed.

Detailed ways

The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. In the present invention, the preferred number of secondary rods is two.

As shown in Figures 1 to 3, the first main rod 1, the second main rod 2, the first primary rod 3 and the third secondary rod 4 of the steel structure converge at one point, and the first main rod 1 and the The end of the second main rod 2 is respectively provided with the first main rod end ear plate 8 and the second main rod end ear plate 9, and the ends of the first rod 3 and the second rod 4 are respectively provided with the first main rod end ear plate 9. The primary rod end lugs 10 and the second rod end lugs 11, all the rod end lugs are preferably welded to the rods; the first main rod 1 and the second main rod 2 are connected through the kingpin 5; The two ends of the pin shaft 5 are provided with two lugs 12 on the shaft, and the lugs 12 on the shaft are preferably welded with the main pin shaft 5; hinged.

This embodiment is only an illustration. If the number of secondary rods is different, the connection angles between the rods are different, and the number of perforated ear plates attached to the main pin shaft is different, the ear plate and the main ear plate should be adjusted according to various situations. The connection angle between the pin shafts is to meet the needs of the tie rod connection. the

The making and assembling steps of the embodiment of the present invention are as follows:

1. The first main rod 1 and the second main rod 2 are welded together with the first main rod end ear plate 8 and the second main rod end ear plate 8 respectively; the first main rod 3 and the second secondary rod Part 4 is welded integrally with the first rod end ear plate 10 and the second rod end ear plate 11 respectively; the kingpin shaft 5 is welded integrally with the two axle ear plates 12 respectively.

2. The kingpin shaft 5 penetrates the first main rod end ear plate 8 and the second main rod end ear plate 9, and hinges the first main rod part 1 and the second main rod part 2.

3. The first pin shaft 6 penetrates the first rod end ear plate 10, and the first rod 3 is hinged with the king pin shaft 5.
