They are also an important component of steel structure buildings. They mostly serve to support the roof structure. Therefore, from the perspective of stability, they are mostly presented and used in a triangular structure.

[0003] A search revealed an existing patent (publication number: CN219690885U) that discloses a steel structure roof truss, including a first connecting frame and a second connecting frame. Two sets of first connecting members are fixedly connected at the connection between the first and second connecting frames. Two sets of second connecting members are fixedly connected at the end of the second connecting frame near the first connecting members. Multiple sets of connecting grooves are formed inside the first connecting members, and threaded grooves are formed inside the connecting grooves. The connecting grooves extend into the interior of the first connecting members and form snap-fit ​​grooves. Multiple sets of fixing grooves are formed inside the second connecting members, and fixing bolts are installed inside the fixing grooves. Compared with existing roof trusses, this utility model can improve the overall practicality of the roof truss through design.

[0004] The existing roof trusses are connected and fixed to the steel structure columns using high-strength bolts and nuts. The bolts can be limited and prevented from loosening using the above-mentioned method. However, the bolt and nut parts are still exposed, which will cause the nuts to rust after long-term use, thus affecting the connection firmness. In addition, it is not easy to disassemble the bolts, resulting in inconvenience in use.

[0005] In view of this, the present invention proposes a modular steel structure roof truss. Utility Model Content

Then, the elastic force of the fixed spring can be used to make the sliding plate descend, which will drive the connecting plate and the protective cover to descend and completely cover the high-strength bolts, nuts and high-strength nuts, reducing the corrosion caused by moisture in the outside air. In addition, the elastic plate on the inner wall of the protective cover can be locked onto the surface of the high-strength bolts, nuts and high-strength nuts, thereby locking and limiting them to prevent the threads from loosening accidentally, which would cause the truss body and column to be unstable. Thus, the high-strength bolts, nuts and high-strength nuts can be covered and protected, improving its practicality.

[0017] 2. In this utility model, a drying block is used to adsorb and dry a small amount of water vapor inside the protective cover, which further improves the dryness of the protective cover and avoids the corrosion of high-strength bolts, nuts and nuts caused by water vapor. When the high-strength bolts and nuts need to be maintained regularly, the thread cover can be opened, and the drying block can be taken out and replaced with a saturated drying block. When installing a new drying block, a sealing gasket can be used to improve the sealing performance between the anti-slip pattern and the thread seat after the threads are tightened.

[0018] 3. In this utility model, the engagement between the convex locking block and the inside of the locking groove improves the accuracy and firmness of the engagement and installation between the truss body and the column, avoids the cumbersome inconvenience of frequently adjusting the installation of the truss body and the column, and improves the convenience of the assembly and installation of the two.

[0026] Example 1

[0027] A preferred embodiment of the modular steel structure roof truss provided by this utility model is, for example... Figures 1 to 4 As shown: A modular steel structure roof truss includes a column 3; a truss body 1 set at the top of the column 3, a high-strength bolt 4 movably connected to the column 3 and the truss body 1, and high-strength nuts 5 with threaded engagement with the surface of the high-strength bolt 4 on both sides of the truss body 1; and an anti-loosening component 2 assembled on the truss body 1 and the column 3, which is used to shield and protect the high-strength bolt 4 and the high-strength nuts 5.

[0028] The anti-loosening component 2 includes: a fixing groove 203 symmetrically opened on the truss body 1 and the column 3; a sliding rod 209 fixedly connected to the inner wall of the fixing groove 203; a sliding plate 207 slidably connected to the surface of the sliding rod 209; a fixing spring 208 wound around the surface of the sliding rod 209; and fixing springs 208 at both ends respectively between the inner top wall of the fixing groove 203 and the top end of the sliding plate 207; a connecting plate 204 rotatably connected to the bottom end of the sliding plate 207; a protective cover 201 fixedly connected to one side of the connecting plate 204; and a dehumidification structure 202 assembled at one end of the protective cover 201, which can be used to adsorb and dry the moisture inside the protective cover 201.

[0029] In this embodiment, after the truss body 1 and column 3 are installed and fixed by high-strength bolts 4 and high-strength nuts 5, the protective cover 201 can be pushed upwards and rotated to be perpendicular to the sliding plate 207. Then, the elastic force of the fixed spring 208 can be used to make the sliding plate 207 descend, causing the connecting plate 204 and the protective cover 201 to descend and completely cover the high-strength bolts 4, nuts and high-strength nuts 5, reducing the corrosion caused by moisture in the outside air.

[0030] In a further preferred embodiment of the present invention, an elastic sheet 205 is fixedly connected at an equal angle to the lower end of the inner wall of the protective cover 201, and one side of the bottom end of the elastic sheet 205 is inclined.

[0031] In this embodiment, the elastic sheet 205 is used to hold the high-strength bolt 4 and the high-strength nut 5 together to prevent the threads from loosening and causing the truss body 1 and the column 3 to be installed loosely.

[0032] In a further preferred embodiment of the present invention, a limiting plate 206 is fixedly connected to one end of the bottom of the sliding plate 207, and the limiting plate 206 is used to limit the rotation of the connecting plate 204.

[0033] In a further preferred embodiment of the present invention, the dehumidification structure 202 includes: a threaded seat 2021 fixedly connected to one end of the protective cover 201, the inner wall of the threaded seat 2021 having a through hole communicating with the inside of the protective cover 201; a threaded cover 2023 threadedly connected to the surface of the threaded seat 2021, and a drying block 2022 placed inside the threaded seat 2021.

[0034] In this embodiment, the drying block 2022 is used to adsorb and dry a small amount of water vapor inside the protective cover 201, thereby further improving the dryness of the protective cover 201. The threaded cover 2023 can be opened to facilitate the replacement of the saturated drying block 2022.

[0035] In a further preferred embodiment of the present invention, the surface of the threaded cover 2023 is provided with anti-slip textures 2025 at equal angles, and the shape of the anti-slip textures 2025 is arc-shaped.

[0036] In this embodiment, the arc-shaped anti-slip texture 2025 is used to improve the anti-slip friction of the user's fingers rotating the surface of the threaded cover 2023.

[0037] In a further preferred embodiment of the present invention, a sealing gasket 2024 is fixedly connected to one end of the inner wall of the anti-slip texture 2025, and the sealing gasket 2024 is O-shaped.

[0038] In this embodiment, the sealing performance between the anti-slip texture 2025 and the threaded seat 2021 after the threads are tightened is improved by using the O-shaped sealing gasket 2024.

[0039] Example 2

[0040] Based on Embodiment 1, a preferred embodiment of the modular steel structure roof truss provided by this utility model is, for example... Figures 1 to 4 As shown: A locking block 6 is welded to one side of the top of the column 3, and the two sides of the bottom of the truss body 1 are provided with locking grooves 7 that engage with the locking block 6. The locking block 6 and the locking grooves 7 are convex in shape.

[0041] In this embodiment, the engagement between the convex locking block 6 and the slot 7 improves the accuracy and stability of the engagement installation between the truss body 1 and the column 3.

[0042] The working principle of this utility model is as follows: The truss body 1 is lifted and placed on the top of the column 3 by an external lifting device. The locking block 6 and the locking groove 7 are used to accurately lock and fix the truss body 1 and the top of the column 3. Then, the protective cover 201 is rotated to drive the connecting plate 204 to rotate until it is flush with the sliding plate 207. Then, the high-strength bolt 4 is passed through the column 3 and the truss body 1 from bottom to top, and the high-strength nut 5 is screwed onto the surface of the high-strength bolt 4. Thus, the truss body 1 and the column 3 are firmly installed through the high-strength bolt 4 and the high-strength nut 5.

[0043] Next, the protective cover 201 is pushed upwards to raise the connecting plate 204, so that the sliding plate 207 slides on the surface of the sliding rod 209 to compress the fixing spring 208 to a suitable distance. Then, the connecting plate 204 is rotated, and the rotation of the connecting plate 204 is limited by the limiting plate 206, so that the connecting plate 204 rotates to be perpendicular to the sliding plate 207. Then, the protective cover 201 is released, and the elastic force of the fixing spring 208 is used to make the sliding plate 207 descend, which in turn causes the connecting plate 204 and the protective cover 201 to descend, completely covering the high-strength bolt 4, nut and high-strength nut 5, reducing the corrosion caused by moisture in the outside air. In addition, the elastic plate 205 on the inner wall of the protective cover 201 can be locked onto the surface of the high-strength bolt 4, nut and high-strength nut 5, thereby locking and limiting them to prevent the threads from loosening accidentally, which would cause the truss body 1 and column 3 to be installed loosely.

[0044] Meanwhile, the threaded seat 2021 and the air inside the protective cover 201 are interconnected, so the small amount of moisture inside the protective cover 201 can be absorbed and dried by the drying block 2022, further improving the dryness inside the protective cover 201. When the high-strength bolt 4 and high-strength nut 5 need to be maintained regularly, the thread cover 2023 can be rotated to open the threaded seat 2021, and then the drying block 2022 can be taken out and replaced with a new one. When installing a new drying block 2022, it can be placed inside the threaded seat 2021, and the anti-slip pattern 2025 threads can be tightened on the surface of the threaded seat 2021. The sealing gasket 2024 is used to improve the sealing performance between the anti-slip pattern 2025 and the threaded seat 2021 after the threads are tightened.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
