Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically a novel supporting steel structure. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. The components are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, steel structures are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. A steel support structure is a support system that uses steel as the main load-bearing material. It is mainly composed of steel beams, steel columns, connectors and other components, which are connected into a whole by welding, bolting and other methods.

[0003] However, the bolts used to fix the steel materials that serve as the raw materials for supporting the steel structure are directly exposed to the outside world. As the usage time increases, the fixing bolts will gradually corrode or rust due to the erosion of the external environment, which will eventually affect the service life of the supporting steel structure fixed by bolts. Therefore, this does not meet the existing needs. To address this, we propose a new type of supporting steel structure. Summary of the Invention

[0004] The purpose of this utility model is to provide a new type of supporting steel structure to solve the problems mentioned in the background art, such as the bolts used to fix the steel materials used as raw materials for supporting steel structures being directly exposed to the outside world, and the bolts gradually corroding or rusting due to the erosion of the external environment as the usage time increases, which will eventually affect the service life of the supporting steel structure fixed by bolts.

The outer side of the two transmission brackets is provided with an internal thread groove on the outer surface of the sealing cover. The inside of the internal thread groove is provided with an external thread sealing and reinforcing ring that matches its internal thread, and the transmission bracket moves laterally through the external thread sealing and reinforcing ring. One side of the internal thread groove is provided with an internal thread reinforcing groove on the outer surface of the supporting steel fixing plate. The internal threads of the internal thread reinforcing groove and the internal thread groove are connected, and the positions of the internal thread groove and the internal thread reinforcing groove correspond to each other.

[0006] Preferably, a manual rotating head is fixedly installed on one side of the outer surface of the circular roller bearing plate, and the circular roller bearing plate and the manual rotating head are fixed together by screws.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] The supporting steel 1 (model Q235-16), the steel structure fixing fastener 4 (model DIN912), and the externally threaded rod 14 (model M10) mentioned in this utility model can all be obtained from the market or through private customization. Please refer to [link / reference]. Figures 1 to 3An embodiment of this utility model is provided: a novel supporting steel structure, including a supporting steel 1, a supporting steel fixing plate 2 is fixedly installed on both the front and rear ends of the supporting steel 1, a steel structure fixing bolt hole 3 is provided on both sides of the front end face of the supporting steel fixing plate 2, and a rotating shaft bracket 5 is fixedly installed on the outer surface of the supporting steel fixing plate 2 on one side of the steel structure fixing bolt hole 3. A sealing cover 6 is fixedly installed on one side of the outer surface of the rotating shaft bracket 5, and the surface of the sealing cover 6 facing the steel structure fixing bolt hole 3 is in contact with the supporting steel fixing plate 2. A circular roller bearing plate 7 is provided on one side of the inside of the sealing cover 6 via a roller bearing. A transmission bracket 8 is fixedly installed on both sides of the circular roller bearing plate 7 facing the nearest supporting steel fixing plate 2. An internal thread groove 9 is provided on the outer side of the two transmission brackets 8 located on the outer surface of the sealing cover 6. An external thread sealing and reinforcing ring 10 matching its internal thread is provided inside the internal thread groove 9, and the transmission bracket 8 moves laterally through the external thread sealing and reinforcing ring 10. One side of the internal thread groove 9 is provided with an internal thread reinforcement groove 11 located on the outer surface of the supporting steel fixing plate 2. The internal thread reinforcement groove 11 is connected to the internal thread of the internal thread groove 9, and the positions of the internal thread groove 9 and the internal thread reinforcement groove 11 correspond to each other.

[0015] The bolt hole 3 for fixing the steel structure contains a fastener 4 for fixing the steel structure, and the fastener 4 includes a bolt and a nut, the diameter of which is smaller than the inner wall diameter of the sealing cover 6. When the fastener 4, consisting of bolts and nuts, is used to fix the support steel fixing plates 2, which are fixed to the outer surface of the support steel 1, to form a support steel structure, the sealing cover 6 is rotated by the rotating shaft bracket 5, so that the sealing cover 6 covers the outside of the fastener 4 exposed on the outer surface of the support steel structure.

[0016] A manual rotating head is fixedly installed on one side of the outer surface of the circular roller bearing plate 7, and the circular roller bearing plate 7 and the manual rotating head are fixed together by screws. After the sealing cover 6 is placed on the outside of the fastener 4 for fixing the steel structure, the circular roller bearing plate 7 is rotated by the manual rotating head. As the circular roller bearing plate 7 rotates, the two transmission brackets 8 fixed to the circular roller bearing plate 7 will rotate synchronously. When the transmission brackets 8 rotate, the external thread sealing reinforcement ring 10 pierced by the two transmission brackets 8 will rotate together. Driven by the internal thread structure of the internal thread groove 9, the rotating external thread sealing reinforcement ring 10 will move back and forth, thus reinforcing the external thread sealing reinforcement ring 10 towards the internal thread. As the external threaded sealing and reinforcing ring 10 moves within the groove 11, it gradually enters the interior of the internal threaded reinforcing groove 11. When the external threaded sealing and reinforcing ring 10 can no longer be moved, it can fix the sealing cover 6 in its current position. The sealing cover 6 fixed here can seal and protect the fastener 4 for fixing the steel structure, thereby preventing the fastener 4 from being corroded by the external environment during long-term use. This technical solution improves the service life of the supporting steel structure. When it is necessary to release the sealing protection of the fastener 4 for fixing the steel structure, simply rotate the circular roller bearing plate 7 in the opposite direction.

[0017] A square rotating shaft 16, fixed to a circular roller bearing plate 7, is provided between two transmission supports 8. An external threaded rod 14, connected to a sealing cover 6 via a threaded structure, is provided on the outer side of the square rotating shaft 16. A square slot 15 is provided on the surface of the external threaded rod 14 facing the circular roller bearing plate 7, into which the square rotating shaft 16 is inserted. The inner wall of the square slot 15 has a square cross-section. The outer surface of the square rotating shaft 16 is in contact with the inner wall of the square slot 15, and the square rotating shaft 16 and the square slot 15 are slidably connected. A piston plate 13 is provided on the surface of the external threaded rod 14 facing the nearest steel structure fixing bolt hole 3. A piston groove 12, located on the inner wall of the sealing cover 6, is provided on the outer side of the piston plate 13. The outer surface of the piston plate 13 is in contact with the inner wall of the piston groove 12, and the piston plate 13 and the piston groove 12 are slidably connected. As the circular roller bearing plate 7 rotates, the square rotating shaft 16 fixed to it will rotate accordingly. As the square shaft 16 rotates, its outer surface fits against the inner wall of the square slot 15 on the outer surface of the external threaded rod 14. When the square shaft 16 rotates, the external threaded rod 14 will rotate synchronously. Through the threaded structure between the external threaded rod 14 and the sealing cover 6, the rotating external threaded rod 14 will move back and forth. As the external threaded sealing and reinforcing ring 10 moves toward the interior of the internal threaded reinforcing groove 11, the external threaded rod 14 will move in the opposite direction. As the external threaded rod 14 moves, the piston plate 13 fixed to it will gradually penetrate into the interior of the piston groove 12, thereby drawing the air inside the sealing cover 6 into the interior of the piston groove 12. The above technical solution can prevent the sealed steel structure fixing fastener 4 from contacting oxygen or moisture in the air, thereby preventing the steel structure fixing fastener 4 from being corroded by the air, and thus further improving the service life of the steel structure fixing fastener 4.
