Description

Technical Field

[0001] The utility model relates to a one-way sliding steel structure hinge node, belonging to the technical field of building design. Background Art

[0002] In the design of steel structure hinged nodes in construction projects, oblong hole nodes are a common form of sliding hinged nodes. It lengthens the circular pin hole on the ear plate into an oblong hole, so that the node has a certain sliding space while rotating. The oblong hole node has a simple structure and low manufacturing and installation costs, but there are some design defects that cannot be ignored: in the oblong hole design node, the contact area between the circular and straight parts is too small, which is prone to stress concentration problems, resulting in wear of the material at the edge of the hole, affecting the long-term performance of the node. On the other hand, as the pin slides and rotates in the hole, friction will occur between the hole wall and the pin, which may cause wear and affect the long-term performance of the node. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a one-way sliding steel structure hinge node, which effectively disperses concentrated stress and reduces material damage caused by local stress concentration through the larger contact area between the slider and the ear plate. This design significantly reduces the stress concentration problem of the node when bearing load and increases the service life of the node.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A one-way sliding steel structure hinge node comprises an ear plate fixedly connected to a main structure, the ear plate is provided with a slide groove, a slider matching the size of the ear plate and capable of sliding relative to the slide groove is provided in the slide groove, a pin hole is provided on the slider, a pin shaft matching the size of the ear plate and capable of rotating relative to the slide groove is provided in the pin hole.

[0006] The aforementioned one-way sliding steel structure hinge node is characterized in that: two symmetrically arranged ear plates are fixedly connected to the main structure, a slider is arranged in the slide groove of each ear plate, and a pin connecting piece is also arranged between the two ear plates, and the pin passes through the pin holes of the two sliders and the positioning hole of the pin connecting piece at the same time.

[0007] The aforementioned one-way sliding steel structure hinge node is characterized in that the inner surface of the pin hole of the sliding block is provided with a lubricating coating.

[0008] The aforementioned one-way sliding steel structure hinge node is characterized in that a lubricating coating is provided on the surface of the pin shaft.

[0009] The aforementioned one-way sliding steel structure hinge node is characterized in that the slide groove is a rectangular structure and the slider is a square structure.

[0010] The aforementioned one-way sliding steel structure hinge node is characterized in that the sliding block is made of high-strength, low-friction material, and the pin connection is made of high-strength material.

[0011] The beneficial effects of the utility model are:

[0012] 1. Good stress dispersion effect: The utility model effectively disperses concentrated stress through the larger contact area between the slider and the ear plate, reducing material damage caused by local stress concentration. This design significantly reduces the stress concentration problem of the node when bearing loads and increases the service life of the node;

[0013] 2. The slider is made of high-strength, low-friction material, and is designed with lubricating material or coating inside, which greatly reduces the friction between the pin and the slider. Compared with the traditional oblong hole node, this design effectively reduces the wear of the pin and extends the service life of the node;

[0014] 3. The pin rotates freely in the middle of the slider, and the slider slides unidirectionally between the ear plates, ensuring the flexibility and reliability of the node in all directions. This design ensures that the node can maintain good articulation function while adapting to structural deformation and displacement requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model will be further described below in conjunction with the accompanying drawings.

[0020] like Figure 1-Figure 4As shown, a one-way sliding steel structure hinge node includes an ear plate 3 fixedly connected to a main structure 5, the ear plate 3 is provided with a slide groove 31, a slider 4 matching the size of the ear plate 31 and capable of sliding relative to the ear plate 31 is provided in the slide groove 31, a pin hole is provided on the slider 4, a pin shaft 2 matching the size of the slider 31 and capable of rotating relative to the slider is provided in the pin hole.

[0021] By setting a slider 4 that can move horizontally relative to the lug 31 of the lug 3, and by rotatably connecting the pin 2 to the pin hole of the slider 4, the function of node articulation is realized through the pin 2, and the slider 4 can slide unidirectionally along the slide 31 in the lug 3 to meet the displacement requirements of the structure. In this structure, during the movement of the slider 4, the larger contact area between the slider and the lug effectively disperses the concentrated stress and reduces the material damage caused by local stress concentration. Moreover, during the rotation of the pin 2 relative to the slider 4, the pin 2 is freely rotated inside the slider to ensure the flexibility of the node, and it will not have any contact with the lug 3. Compared with the articulation mode in which the pin directly slides and rotates in the oblong hole of the lug, its relative wear is very small, which can greatly improve the service life of the node.

[0022] Two symmetrically arranged ear plates 3 are fixedly connected to the main structure 5, a slider 4 is arranged in the slide groove 31 of each ear plate 3, and a pin connector 1 is arranged between the two ear plates 3, and the pin 2 passes through the pin holes of the two sliders 4 and the positioning hole 11 of the pin connector 1 at the same time.

[0023] The pin connector 1 is fixed in place by the pin 2 and plays a key role in connection and force transmission in the entire structure. It realizes the transmission of force and relative movement between structural components. The pin connector 1 is made of high-strength alloy steel and other materials. Through fine processing, the matching accuracy between it, the pin 2 and the slider 4 is ensured, thereby ensuring the firmness and stability of the overall connection. This design enables the pin connector 1 to reliably withstand high loads, while allowing the pin 2 to rotate freely in the middle part of the left and right sliders 4, while achieving the stiffness of the node and the flexibility between the slider and the node.

[0024] The inner surface of the pin hole of the slider 4 is provided with a lubricating coating, and the surface of the pin shaft 2 is provided with a lubricating coating. By providing a lubricating coating on the inner surface of the pin hole of the slider 4 and the outer surface of the pin shaft 2, the friction between the two during relative rotation is further reduced and wear is prevented.

[0025] The slide groove 31 is a rectangular structure, and the slider 4 is a square structure. Due to the rectangular design, the contact area between the ear plate 3 and the slider 4 is larger, which helps to disperse the concentrated stress and reduce the damage to the material caused by the stress concentration.

[0026] The slider 4 is made of high-strength, low-friction material, and the pin connector 1 is made of high-strength material, such as high-strength steel or high-performance engineering plastic, to enhance the strength of the entire node.

[0027] In summary, the utility model provides a one-way sliding steel structure hinge node, which effectively disperses concentrated stress and reduces material damage caused by local stress concentration through a larger contact area between the slider and the ear plate. This design significantly reduces the stress concentration problem of the node when bearing load and increases the service life of the node.
