Description

Technical Field

[0002] Steel space frame structures are widely used due to their advantages such as good spatial stiffness, light weight, economical material usage, factory prefabrication, and aesthetically pleasing appearance. In space frame structures, the load-bearing capacity of bolted ball joints plays a decisive role in structural safety.

[0003] However, in actual engineering projects, the bolted ball joints of space frame structures, or both bolted ball joints and tie rods, may simultaneously require reinforcement. Reasons include: the prevalence of construction defects and overloads, often resulting in varying degrees of damage to joints and tie rods, leading to reduced load-bearing capacity and safety of the space frame structure; damage, corrosion, or aging of the bolted ball joints due to long-term use, causing their load-bearing capacity to fail to meet design requirements; and changes in building function, higher design standards, or the addition of photovoltaic equipment to the roof, rendering the original space frame joints unable to meet safety requirements. Considering the economic cost of complete demolition and reconstruction, it is usually necessary to strengthen and modify existing space frames using partial or overall reinforcement measures to meet load-bearing capacity and normal usage requirements.

[0036] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0038] Bolted ball space frame structures are widely used due to their advantages such as good spatial stiffness, light weight, economical material usage, factory prefabrication, and aesthetically pleasing design. In bolted ball space frame structures, the load-bearing capacity of the bolted ball joints plays a decisive role in structural safety. However, in actual engineering projects, bolted ball joints often encounter the following problems: due to defects in construction techniques and the prevalence of overloading, bolted ball joints are often damaged to varying degrees, leading to a reduction in their load-bearing capacity and safety; due to long-term use, bolted ball joints suffer damage, corrosion, or aging, causing their load-bearing capacity to fail to meet design requirements; changes in building function, higher design standards, or the addition of photovoltaic equipment to the roof can render the original bolted ball joints unable to meet safety requirements. However, considering the economic cost of demolition and reconstruction, it is usually necessary to reinforce or modify the existing space frame structure to meet its load-bearing capacity and normal use requirements.

[0039] In related technologies, the reinforcement structure of bolted ball joints in bolted ball space frame structures has problems such as difficulty in connecting with the bolted ball space frame structure, large operating space required, and poor reinforcement effect.

[0040] To address the aforementioned technical problems, this application provides a reinforcement device and method for bolted ball grid nodes and tie rods. The reinforcement device for bolted ball grid nodes and tie rods is easy to connect with the bolted ball grid structure, requires little operating space, and provides good reinforcement effect.

[0041] Please see Figure 1 and Figure 2 This application provides a reinforcement device for bolted ball grid nodes and tie rods. The bolted ball node includes a bolted ball 1 and tie rods 3 symmetrically arranged on both sides of the bolted ball 1. The reinforcement device for bolted ball grid nodes and tie rods includes a sleeve assembly, a first wing block, and a connecting rod 6. The sleeve assembly includes a pair of sleeves 4, each sleeve 4 including multiple sleeve units 101 distributed around itself circumferentially. Adjacent sleeve units 101 of the same sleeve 4 are connected to each other. The paired sleeves 4 can be symmetrically distributed on both sides of the bolted ball 1, and each sleeve 4 can be sleeved on one of the tie rods 3 and connected to the tie rod 3. The paired sleeves 4 are provided with opposite first wing blocks. Each first wing block includes a first half-wing block 11 and a second half-wing block 13. The first half-wing block 11 is connected to one of the two adjacent sleeve units 101 in the same sleeve 4, and the second half-wing block 13 is connected to the other of the two adjacent sleeve units 101. A connecting rod 6 connects the first wing blocks on the paired sleeves 4, and the connecting rod 6 fixes the relative positions of the first half-wing block 11 and the second half-wing block 13.

[0042] Bolt ball 1 is a spherical structure with a threaded hole. A cone head 2 is connected to the tie rod 3, and a high-strength bolt is installed on the cone head 2. The tie rod 3 can be screwed to the bolt ball 1 through the high-strength bolt on the cone head 2.

[0043] Each sleeve 4 can be optionally configured to include two, three, or more sleeve units 101 distributed around its circumference. The configuration of each sleeve 4 with multiple sleeve units 101 distributed around its circumference not only improves the adaptability and flexibility of the sleeve 4, but also enhances its structural strength and rigidity, facilitates maintenance and replacement, improves the reliability of the connection between the sleeve 4 and the tie rod 3, optimizes material utilization, and increases construction efficiency.

[0044] For example, each sleeve 4 may include two sleeve units 101 distributed around itself in the circumferential direction, which not only makes the structure of the sleeve 4 simpler, but also facilitates the sleeve 4 to be sleeved on the pull rod 3 while improving the fit between the sleeve 4 and the pull rod 3.

[0045] The first half-wing block 11 may have the same external dimensions as the second half-wing block 13, or it may have different external dimensions from the second half-wing block 13.

[0046] Optionally, the first half-wing block 11 and the second half-wing block 13 have the same external dimensions, which not only facilitates the processing and production of the first half-wing block 11 and the second half-wing block 13, but also facilitates the combination of the first half-wing block 11 and the second half-wing block 13, thereby realizing the connection between the first wing block and the connecting rod 6.

[0047] The dimensions of the first wing block, the first half-wing block 11, and the second half-wing block 13 are matched. For example, the first wing block is a cubic structure, the first half-wing block 11 and the second half-wing block 13 are both cubic structures, the first wing block is a cylindrical structure, and the first half-wing block 11 and the second half-wing block 13 are both semi-cylindrical structures.

[0048] The inner wall of the sleeve 4 and the outer wall of the tie rod 3 can be connected by means of bonding, interference fit, etc.

[0049] In summary, according to one embodiment of this application, a reinforcement device for a bolted ball grid node and tie rods is provided. The bolted ball node includes a bolted ball 1 and tie rods 3 symmetrically arranged on both sides of the bolted ball 1. The reinforcement device for the bolted ball grid node and tie rods includes a sleeve assembly, a first wing block, and a connecting rod 6. The sleeve assembly includes a pair of sleeves 4, each sleeve 4 including a plurality of sleeve units 101 distributed around itself circumferentially, and the two sleeve units 101 of the same sleeve 4 are connected to each other. The paired sleeves 4 have first wing blocks arranged opposite each other. Each first wing block includes a first half-wing block 11 and a second half-wing block 13. The first half-wing block 11 is connected to one of the two adjacent sleeve units 101 in the same sleeve 4, and the second half-wing block 13 is connected to the other of the two adjacent sleeve units 101. By connecting the first wing blocks on the paired sleeves 4 with connecting rods 6, not only can the sleeves 4 be fitted onto the tie rods 3 to fix the relative positions between the sleeve units 101, but the paired sleeves 4 can also be connected. Therefore, each sleeve 4 is fitted onto one of the tie rods 3, and the connection between the connecting rod 6 and the first wing block can reduce or avoid the probability of connecting the tie rod 3 to the bolt ball joint by welding or screwing, etc., with less connection difficulty and less operating space required. The connecting rods 6 connecting the first wing blocks on the paired sleeves 4 provide good reinforcement.

The second wing blocks 5 are arranged opposite each other on the paired sleeves 4. The first wing blocks and the second wing blocks 5 located on the same sleeve 4 are distributed circumferentially at intervals. The second wing blocks 5 arranged on the paired sleeves 4 are connected by a connecting rod 6.

[0051] The second wing block 5 may have the same external dimensions as the first wing block, or it may have different external dimensions.

[0052] Optionally, the second wing block 5 has the same external dimensions as the first wing block, which not only facilitates the processing and production of the second wing block 5, but also enables the first wing block and the second wing block 5 to be connected to the connecting rod 6 of the same size, thus facilitating the processing and production of the connecting rod 6.

[0053] One embodiment of this application provides a reinforcement device for bolted ball joint nodes and tie rods. The device uses a pair of sleeves 4 with oppositely arranged second wing blocks 5, and a connecting rod 6 connects the pair of sleeves 4 with the second wing blocks 5. This further increases the connection strength between the pair of sleeves 4 and improves the reinforcement effect of the bolted ball joint.

[0056] Optionally, the first wing block is inserted and fixed to the connecting rod 6.
