Description

Technical Field

[0001] The utility model belongs to the technical field of steel structures, and particularly relates to a steel structure grid with high-strength bolt connections. Background Technique

[0002] A steel structure grid is a network structure composed of steel, which has the advantages of light self-weight, large applicable span, material saving, fast construction speed, etc., and is widely used in buildings such as stadiums, theaters, and exhibition halls. The current grids use solid rods for connection, and different nodes need to be installed simultaneously, making the installation process cumbersome.

[0003] After retrieval, the publication number: CN216664481U discloses a steel structure grid. A metal ball is connected to another metal ball on the upper side through a vertically distributed second connecting rod, or is connected to another metal ball distributed along the diagonal through an inclined second connecting rod. Both the second connecting rod and the second connecting rod are provided with screw heads. A limiting disc is provided at one end of the screw head located inside the rod body. Additionally, through the installed spring, the screw head is always pushed out. A section of the screw head close to the limiting disc is a prismatic structure, which is convenient for screwing and installing. First, a plurality of metal balls are installed in a straight line through a clamp and a first connecting rod, and the connection of multiple rows of metal balls is realized through the second connecting rod and the third connecting rod installed on the side of the second connecting rod axis, forming a metal ceiling structure. Although this device forms a ceiling through the staggered welding of multiple groups of connecting rods, the construction cost is slightly high. The welding method makes the ceiling a fixed structure and cannot be adjusted to adapt to different occasions, thereby reducing the practicality.

[0004] Therefore, a steel structure grid with high-strength bolt connections is designed to solve the above problems. Content of the Utility Model

[0005] To solve the problems raised in the above background technique, the utility model provides a steel structure grid with high-strength bolt connections. This device can be flexibly opened and closed according to the usable area of the site. During specific operation, a person touches the rubber block and holds the rotating block, and rotates along the center. Under the screw thread cooperation of the thread groove and the lead screw of the first screw rod, the first screw rod pushes the X-axis support to drive the steel main beam to move outward along the bottom of the steel grid. Since the steel main beam abuts against the steel grid, when the steel main beam moves, the two groups of steel grids can rotate along both ends of the corrosion-resistant shaft, and the synchronous opening and closing effect of the two groups of steel grids is ensured, enabling this device to increase or decrease the floor area and improve the practicality.

[0006] During the installation process, two workers cooperate to adjust the components to complete fine-tuning. During the fine-tuning process, the worker can turn the rotating handle, which drives the second screw to rotate. The second screw pushes the movable block outwards along the internal thread of the hollow steel plate. During this process, since the top of the limit frame is always embedded inside the steel grid frame, under the combined effect of the threaded push, the stability of the movable block during translation is improved. The two groups of steel grid frames rotate along the corrosion-resistant shaft, and cooperate with the abutting steel main beams, so that the two groups of steel grid frames can complete angle fine-tuning at the shed roof, enabling the device to adapt to different occasions.

[0007] To achieve the above object, the present utility model provides the following technical solutions: a steel structure grid frame connected by high-strength bolts, including a bolt-connected steel frame. The bolt-connected steel frame includes a steel grid frame, a steel main beam, a corrosion-resistant shaft, an X-axis bracket, a first screw, a rotating block, and a wrapped hollow rod. The steel main beam is slidably connected to the outer side of the bottom of the steel grid frame. The corrosion-resistant shaft is sleeved inside the top of the steel grid frame. The X-axis bracket is fixedly connected to the opposite side surface of the steel main beam. The first screw is fixedly connected to the outside of the X-axis bracket. The wrapped hollow rod is sleeved outside the first screw. The rotating block is threadedly connected to the outside of the first screw. An adjusting component is further provided at the connection between the steel main beam and the steel grid frame.

[0008] Preferably, a circular hole and a limit spring are further provided inside the rotating block. The inner diameter of the circular hole is equal to the outer diameter of the wrapped hollow rod. Both ends of the limit spring are fixedly connected to the surface of the wrapped hollow rod and the rotating block respectively.

[0009] Preferably, the adjusting component includes a hollow steel plate, a rotating handle, a second screw, a movable block, and a hanging ring. The hollow steel plate is fixedly connected to the bottom surface of the steel grid frame. One end of the rotating handle is fixedly connected to the outside of the top of the second screw. The movable block is rotatably connected to the outside of the second screw. Both sides of the hanging ring are fixedly connected to the opposite side surfaces of the movable block and the steel main beam respectively.

[0010] Preferably, a limit frame is further provided inside the steel grid frame. The limit frame is sleeved inside the steel grid frame for connecting the movable block.

[0011] Preferably, a rubber soft pad is further attached to the surface of the rotating block.

[0012] Preferably, a thread groove matching the size of the first screw is further opened inside the rotating block.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. In the present utility model, a human hand touches the rubber block and holds the rotating block, and rotates along the center. Under the cooperation of the thread groove and the lead screw of the first lead screw, the first lead screw pushes the X-axis bracket to drive the steel main beam to move outward along the bottom of the steel grid. Since the steel main beam abuts against the steel grid, when the steel main beam moves, the two groups of steel grids can rotate along both ends of the corrosion-resistant shaft, and the synchronous opening and closing effect of the two groups of steel grids is ensured, so that the area occupied by the device can be increased or decreased, and the practicability is improved.

[0015] 2. In the present utility model, the staff can turn the rotating handle. Under the combined effect of the thread push, the stability of the movable block during the translation process is improved. The two groups of steel grids rotate along the corrosion-resistant shaft, and cooperate with the abutting steel main beam, so that the two groups of steel grids can complete angle fine-tuning at the roof, so that the device can be adapted to different occasions.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figure 1 shown:

[0026] For the steel structure grid connected by high-strength bolts, as known from CN216664481U, through the installed spring, the screw head is always pushed out. The section of the screw head close to the limit disc is a prism structure, which is convenient for screwing and installation. First, a number of metal balls are installed in a straight line through a clamp and a first connecting rod. The connection of multiple rows of metal balls is realized through a second connecting rod and third connecting rods installed on the side of the second connecting rod shaft, forming a metal ceiling structure. Although this device forms a ceiling through staggered welding of multiple groups of connecting rods, the construction cost is slightly high. Through the welding method, the ceiling is a fixed structure and cannot be adjusted to adapt to different occasions, thus reducing the practicability. On this basis, a bolt-connected steel frame 1 is added.

[0027] As Figure 1 、 Figure 2 and Figure 3 shown:

[0028] In an alternative embodiment: The bolt-connected steel frame 1 includes a steel grid 11, a steel main beam 12, a corrosion-resistant shaft 13, an X-axis bracket 14, a first screw 15, a rotating block 16, and a wrapped hollow rod 17. The steel main beam 12 is slidably connected to the outer side of the bottom of the steel grid 11. The corrosion-resistant shaft 13 is sleeved on the inner side of the top of the steel grid 11. The X-axis bracket 14 is fixedly connected to the opposite side surface of the steel main beam 12. The first screw 15 is fixedly connected to the outer side of the X-axis bracket 14. The wrapped hollow rod 17 is sleeved outside the first screw 15. The rotating block 16 is threadedly connected to the outer side of the first screw 15. A circular hole 3 and a limiting spring 4 are further provided inside the rotating block 16. The inner diameter of the circular hole 3 is equal to the outer diameter of the wrapped hollow rod 17. The two ends of the limiting spring 4 are fixedly connected to the surfaces of the wrapped hollow rod 17 and the rotating block 16 respectively. A rubber soft pad 6 is also attached to the surface of the rotating block 16.

[0029] In this implementation: This device can be flexibly opened and closed according to the usable area of the site. During specific operation, a person touches the rubber block and holds the rotating block 16, and rotates it along the center. Under the screw rod cooperation of the threaded groove 7 and the first screw rod 15, the first screw rod 15 pushes the X-axis bracket 14 to drive the steel main beam 12 to move outward along the bottom of the steel grid 11. The wrapped hollow rod 17 is always sleeved outside the first screw rod 15 under the elastic force of the limit spring 4, increasing protection; since the steel main beam 12 abuts against the steel grid 11, when the steel main beam 12 moves, the two groups of steel grids 11 can rotate along both ends of the corrosion-resistant shaft 13, and ensure the synchronous opening and closing effect of the two groups of steel grids 11, enabling this device to increase or decrease the floor area and improve practicality.

[0030] Furthermore:

[0031] As Figure 1 、 Figure 4 and Figure 5 shown:

[0032] In an alternative embodiment: The adjustment assembly 2 includes a hollow steel plate 21, a rotating handle 22, a second screw rod 23, a movable block 24 and a lifting ring 25. The hollow steel plate 21 is fixedly connected to the bottom surface of the steel grid 11. One end of the rotating handle 22 is fixedly connected to the outer side of the top of the second screw rod 23. The movable block 24 is rotatably connected to the outer side of the second screw rod 23. Both sides of the lifting ring 25 are fixedly connected to the opposite side surfaces of the movable block 24 and the steel main beam 12 respectively. A limit frame 5 is also provided inside the steel grid 11. The limit frame 5 is sleeved inside the steel grid 11 for connecting the movable block 24. A threaded groove 7 matching the size of the first screw rod 15 is also opened inside the rotating block 16.

[0033] In this embodiment: During the installation process, two workers cooperate with the adjustment assembly 2 to complete fine adjustment. During the fine adjustment process, the worker can turn the rotating handle 22, and the rotating handle 22 drives the second screw rod 23 to rotate. The second screw rod 23 pushes the movable block 24 outward along the internal thread of the hollow steel plate 21. During this process, since the top of the limit frame 5 is always embedded inside the steel grid 11, under the combined effect of the screw thread pushing, the stability of the movable block 24 during translation is improved. The two groups of steel grids 11 rotate along the corrosion-resistant shaft 13, and cooperate with the abutting steel main beam 12, enabling the two groups of steel grids 11 to complete angle fine adjustment at the roof, enabling this device to adapt to different occasions.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
