Description

Technical Field

[0001] This utility model relates to the field of space frame technology, and more specifically, to a steel structure reinforcement mechanism in a large space frame structure. Background Technology

[0002] Space frame structures, as a type of highly statically indeterminate spatial truss structure, are widely used in industrial and civil construction due to their excellent load-bearing performance, high stiffness, good integrity and seismic performance, economic efficiency, safety, and ease of fabrication and installation. Especially in recent years, with the widespread use of computers, the design and calculation of space frame structures have become very simple. However, after a space frame structure is built and put into use, changes in its function, renovation, or increased load may cause it to no longer meet the required usage. When the calculated strength, stiffness, and stability of the structure fail to meet the functional requirements and original design specifications, measures must be taken to ensure the structure's safety. Without such measures, any damage will inevitably result in significant personal injury and property loss.

[0003] Chinese Patent No. CN217269050U provides a high-strength reinforcement structure for space frame tie rods, comprising a space frame body formed by multiple tie rods and bolt ball joints. A reinforcement mechanism is provided between the tie rods in the space frame body. The reinforcement mechanism includes a reinforcement rod with positioning mechanisms at both ends, which are fixed to the tie rod. The positioning mechanism includes a reinforcement clamp fixed to the tie rod. The reinforcement clamp includes two semi-circular clamp bodies that are split apart, with positioning plates at both ends of each clamp body. Positioning through holes are provided on the positioning plates, and positioning bolts are inserted between the positioning through holes of the two clamp bodies. Locking nuts are threaded into the ends of the positioning bolts. This utility model provides a reinforcement mechanism between the tie rods to strengthen the existing space frame body, thereby effectively improving the structural strength of the space frame body.

[0004] Currently, in existing large-scale space frame structures, although the steel structure reinforcement mechanisms can improve the strength of the space frame, for the lower chord, the method of connecting the lower chord members solely with bolts and lower chord balls can easily cause the bolts to be subjected to large shear forces and deform. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a steel structure reinforcement mechanism for large space frame structures, aiming to improve the steel structure reinforcement mechanism in large space frame structures. Under normal circumstances, the lower chord and the lower chord ball are closely connected by bolts, which easily causes the bolts to bear large shear forces.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a steel structure reinforcement mechanism for a large space frame structure, including a connecting structure and a reinforcement structure fixed at the bottom of the connecting structure. The connecting structure includes a lower chord ball and a connector. The reinforcement structure includes a top fastener and a tension member. The tension member is slidably connected to one side of the top fastener. The top fastener includes a hanger rod, which is fixed to the bottom of the lower chord ball. One side of the hanger rod is provided with threads, and a threaded sleeve is threaded to the threaded side. A limiting frame is fixed to the end of the hanger rod. A top rod is rotatably connected inside the limiting frame, and a rotating block is fixed to one side of the top rod.

[0008] In one embodiment of this utility model, the lower chord ball is internally threaded with a bolt post, a sleeve is sleeved on one side of the bolt post, and a pin is internally threaded with the sleeve.

[0009] In one embodiment of this utility model, a lower chord is rotatably connected to the end of the bolt column, and a web member is threadedly connected to one side of the lower chord ball.

[0010] In one embodiment of this utility model, the connector includes a collar, which is sleeved on one side of the web member. A threaded end is fixed on one side of the collar, and a connecting rod is provided on one side of the threaded end.

[0011] In one embodiment of this utility model, a limiting plate is fixed at the end of the connecting rod, and a threaded sleeve is sleeved on one side of the connecting rod.

[0012] In one embodiment of this utility model, the pulling member includes a second limiting frame, which is slidably connected to one side of the lifting rod. A rotating shaft is slidably connected inside the second limiting frame, and a pulling rod is rotatably connected to one side of the rotating shaft.

[0013] In one embodiment of this utility model, the pull rod is rotatably connected to one side of the rotating block, and the limiting frame 2 is internally threaded with an adjusting bolt.

[0014] Compared with the prior art, the steel structure reinforcement mechanism in a large space frame structure obtained by the above design of this utility model, when in use, utilizes the rotation of the screw sleeve to allow the screw sleeve to push the second limiting frame to move upward, thus enabling the tie rod to pull the top rod to rotate, thereby allowing the top rod to push against the lower chord, thus ensuring that the top rod supports the lower chord, thereby sharing part of the load-bearing force of the bolt column through the top rod.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0023] Please see Figure 1-5This utility model provides a technical solution: a steel structure reinforcement mechanism for a large space frame structure, including a connecting structure 100 and a reinforcement structure 200 fixed to the bottom of the connecting structure 100. The connecting structure 100 includes a lower chord ball 110 and a connector 120, with the lower chord ball 110 serving as a transition connection. The reinforcement structure 200 includes a top fastener 210 and a tension member 220, with the tension member 220 slidably connected to one side of the top fastener 210. The top fastener 210 includes a hanger rod 211, which serves as a limiting support. Rod 211 is fixed to the bottom of the lower chord ball 110. One side of the rod 211 is provided with thread 212, which is a thread. A threaded sleeve 213 is threaded to one side of the thread 212. The threaded sleeve 213 can move up and down through the threaded connection on the rod 211. A limiting frame 214 is fixed to the end of the rod 211. A top rod 215 is rotatably connected inside the limiting frame 214. The end of the top rod 215 has a pad, which can push against the lower chord rod 114. A rotating block 216 is fixed to one side of the top rod 215. The rotating block 216 serves as a transition connection.

[0024] Please see Figure 1-3 The lower chord ball 110 is internally threaded with a bolt post 111. A sleeve 112 is fitted onto one side of the bolt post 111. A pin 113 is internally threaded onto the sleeve 112. The pin 113 ensures that the bolt post 111 rotates with the sleeve 112. The lower chord rod 114 is rotatably connected to the end of the bolt post 111. A web rod 115 is threaded onto one side of the lower chord ball 110. The connecting piece 120 includes a collar 121, which is fitted onto one side of the web rod 115. A threaded end 122 is fixed to one side of the collar 121. The threaded end 122 is threadedly connected to the threaded sleeve 125. A connecting rod 123 is provided on one side of the threaded end 122. A limit plate 124 is fixed to the end of the connecting rod 123. The limit plate 124 restricts the threaded sleeve 125 from being pulled off the connecting rod 123. The threaded sleeve 125 is fitted onto one side of the connecting rod 123.

[0025] Please see Figure 1 and Figure 4-5 The pulling component 220 includes a second limiting frame 221, which is slidably connected to one side of the lifting rod 211. A rotating shaft 222 is slidably connected inside the second limiting frame 221. A pull rod 223 is rotatably connected to one side of the rotating shaft 222. The pull rod 223 is rotatably connected to one side of the rotating block 216. An adjusting bolt 224 is threaded inside the second limiting frame 221. Rotating the adjusting bolt 224 can adjust the position of the rotating shaft 222, thereby achieving fine adjustment of the tilt angle of the top rod 215.

[0026] Specifically, the working principle of the steel structure reinforcement mechanism in this large space frame structure is as follows: Before installing the web members 115, the collar 121 is put on. After the space frame is built, the connecting rod 123 is connected to the threaded end 122 by the threaded connection between the threaded sleeve 125 and the threaded end 122. This allows the web members 115 to be connected in pairs through the connecting rods 123, which can effectively reduce the downward drooping of the web members 115 due to gravity. By rotating the threaded sleeve 213, the second limiting frame 221 can be moved upward, which allows the tie rod 223 to pull the top rod 215 to rotate around the first limiting frame 214 as the base point. Therefore, the top rod 215 can push against the lower chord 114. Thus, by supporting the lower chord 114, the top rod 215 can reduce the shear force of the bolt column 111, thereby ensuring that the large space frame will not deform and shift excessively after the construction is completed.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
