Description

Technical Field

[0001] This application relates to the field of prefabricated timber structure buildings, and more specifically, it relates to an eccentric secondary beam connector. Background Technology

[0002] In prefabricated timber structures, due to their large spans and high floor heights, beam-column frame structures are often used. In some cases, the main and secondary beams may exhibit eccentricity, causing the centerlines of the frame beams and columns to misalign. Under earthquakes, this can lead to insufficient shear area in the core zone, resulting in adverse torsional effects on the columns. It also reduces the effective width of beam-column joints, decreasing load-bearing capacity and worsening the stress on frame columns and beam-column joints, potentially causing frame failure. To ensure structural stability, metal connectors and pins are typically used to connect the main beams and eccentric secondary beams. To further enhance overall structural stability, overlapping beams and web members are used for support. However, pin connections are semi-rigid, prone to lateral bending, and easily form hinged joints with poor stability. While the support of web members can reduce the risk of lateral bending, it leads to excessive use of metal connectors at the joints, reducing the effective cross-section of the timber structure. Furthermore, in actual construction, fixing the eccentric secondary beams is difficult due to the large size of the structure. Summary of the Invention

[0003] This application provides an eccentric secondary beam connector, which not only allows the component to have a larger effective area for vertical load-bearing capacity, but also enables adjustment of the beam support position, reduces the positional error of the beam structure, improves construction convenience, and enhances the stability of the beam structure.

[0004] This application provides an eccentric secondary beam connector, which adopts the following technical solution:

[0005] An eccentric secondary beam connector includes a connecting sleeve and a beam support. The connecting sleeve has protrusions and recesses on its sidewalls, each protrusion including a raised portion and a recess connected to one end of the raised portion. The connecting sleeve has at least two raised portions and two recesses on its sidewall where it connects to the beam support, with the raised portions and recesses facing each other along the length of the connecting sleeve. The beam support has an adjusting block inserted into the recess between two adjacent raised portions. The sidewalls of both the raised portions and the recesses are in contact with the adjusting block. A connector is provided between the beam support and the connecting sleeve.

[0006] Furthermore, both the protrusions and the recesses are rectangular sheets, and the sidewalls of both the protrusions and the recesses are connected to the sidewalls of the connecting sleeve.

[0007] Furthermore, both the protrusion and the recess are frame-shaped, and the inner peripheral walls of both the protrusion and the recess are connected to the side wall of the connecting sleeve.

[0008] Furthermore, both the protrusion and the recess are fitted to the connecting sleeve, and both the protrusion and the recess are connected to the connecting sleeve by a fixing member.

[0009] Furthermore, the beam support and the concave and convex parts are welded together, and the connecting parts are welded joints formed by welding.

[0010] Furthermore, the connector includes a connecting block connected to the beam support, the connecting block being connected to the male and female members by bolts.

[0011] In summary, this application has the following beneficial effects:

[0012] 1. The connecting sleeve of this application connects vertical members in the form of a sleeve, reducing damage to the cross section, giving the members more effective area for vertical bearing capacity, making the connection between the main and secondary beams more stable, and eliminating nail-type connections within the main structural frame system.

[0013] 2. This application includes concave and convex parts. On the one hand, the concave and convex parts can serve as reinforcements to improve the stress strength of the connecting sleeve. On the other hand, the concave and convex shapes of the concave and convex parts enhance the guiding, limiting, and stabilizing functions of the beam support when adjusting its position laterally. This not only facilitates personnel operation but also reduces secondary displacement of the beam support and improves structural stability.

[0014] 3. The protrusion and concave part of this application adopts a connection method that fits into the connecting sleeve. Therefore, the protrusion and concave part can move on the connecting sleeve before being fixed, thereby realizing the vertical adjustment of the protrusion and concave part, and thus realizing the vertical adjustment of the beam support. This application enables the beam support to be adjusted in all directions, and the beam support can fix the beam structure in the specified position, thereby improving the structural stability of the final component.

[0019] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] Example 1

[0021] like Figure 1 As shown, Embodiment 1 provides an eccentric secondary beam connector, including a connecting sleeve 1 and a beam support 2. The connecting sleeve 1 is a rectangular sleeve with a protrusion-contact part 3 installed on its side wall. The protrusion-contact part 3 includes a protrusion 31 and a recess 32 integrally connected to one end of the protrusion 31. In this embodiment, both the protrusion 31 and the recess 32 are frame-shaped, and the inner peripheral walls of both the protrusion 31 and the recess 32 are in contact with the side wall of the connecting sleeve 1. In this embodiment, both the protrusion 31 and the recess 32 are connected to the connecting sleeve 1 by a fixing part 4. In this embodiment, the fixing part 4 is a welding point formed by welding. The position of the welding point can be adjusted according to the actual situation to achieve the connection between the components. In addition, in actual construction, it can also be fixed by bolts or other methods.

[0022] In this embodiment, there are two protrusions / concaves 3. Therefore, the vertical sidewalls of the connecting sleeve 1 that need to connect to the beam support 2 are each connected to two protrusions 31 and two recesses 32. The recesses 32 of the upper protrusion / concave 3 and the protrusions 31 of the lower protrusion / concave 3 are fitted together, that is, the protrusions 31 and the recesses 32 are in contact along the length of the connecting sleeve 1, thereby forming a groove 6 between the two protrusions / concaves 3. An adjusting block 21 is fixedly connected to the beam support 2. The adjusting block 21 is inserted into the recesses 32 between two adjacent protrusions 31. The sidewalls of both the protrusions 31 and the recesses 32 are fitted with the adjusting block 21, that is, the adjusting block is inserted into the groove 6 and fits against the groove wall of the groove 6. A connecting member 5 is also provided between the beam support 2 and the connecting sleeve 1. In this embodiment, the beam support 2 and the protrusions / concaves 3 are welded. The connecting member 5 is the weld point formed by the welding. The position of the weld point can be adjusted according to the actual situation to achieve the connection between the components.

[0023] The working principle of this embodiment is as follows: Based on the required installation height, the protrusion / concave part 3 is slidably moved on the connecting sleeve 1. At this point, the protrusion / concave part 3 and the connecting sleeve 1 are in a fitted relationship but not fixedly connected. After moving the protrusion / concave part 3 to a suitable height, it is fixed to the connecting sleeve 1 by welding. At this time, the recessed parts 32 between adjacent protrusions 31 form a groove 6. Then, the adjusting block 1 is inserted into the groove 6, which limits the height of the beam support 2. The adjusting block 21 is then slid laterally in the groove 6 to adjust the left and right positions of the beam support 2. After adjusting the beam support 2 to a suitable position, the beam support 2 and the protrusion / concave part 3 are welded together, and subsequent construction can proceed. The number of beam supports 2 depends on the actual construction situation.

[0024] Example 2

[0025] like Figure 2As shown, the difference between Embodiment 2 and Embodiment 1 is that the protrusions 31 and recesses 32 in this embodiment are both rectangular sheets. That is, two protrusions and recesses 3 are individually installed on each vertical sidewall of the connecting sleeve 1 that needs to be connected to the beam support 2. Thus, each vertical sidewall of the connecting sleeve 1 to be connected has two protrusions 31 and two recesses 32. The sheet-like protrusions and recesses 3 make the protrusions and recesses 3 on the sidewall of the connecting sleeve 1 independent of each other and their positions can be adjusted individually. Whether or not protrusions and recesses 3 are installed on the sidewall of the sleeve 1 can be determined according to the situation.

[0026] Example 3

[0027] like Figure 3 As shown, the difference between Embodiment 3 and Embodiment 1 is that the connector 5 in this embodiment includes a connector 51 connected to the beam support 2. The connector 51 is inserted into the groove 6 and fits against the groove wall of the groove 6. The connector 51 is connected to the groove wall of the groove 6 by bolts. The connector 51 can also be fixed in other positions to realize the connection between the beam support 2 and the concave and convex parts 3 and the connector sleeve 1.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
