Description

Technical Field

[0001] This invention relates to the field of reinforcement device technology, specifically a reinforcement device for steel structures. Background Technology

[0002] In the field of construction, building components are crucial to the completion of a building. Regardless of the type of building components used in construction, the strength, stiffness, and stability of the building structure and its components must meet various performance requirements under different conditions. Supporting beams are indispensable components in buildings.

[0003] Chinese patent CN214786218U discloses a steel structure reinforcement device, comprising: a main support beam with a mounting plate fixedly mounted on it, one end of which is inserted into and welded to the main support beam; an auxiliary beam installed between two main support beams, with both ends welded to the mounting plates on the main support beams; and a support device including a threaded rod, a threaded sleeve, a connector, and a support plate. The threaded sleeve is fixedly mounted on the auxiliary beam, the threaded rod is threaded to the threaded sleeve, one end of the threaded rod is rotatably connected to one end of the connector, and the other end of the connector is fixedly connected to the support plate. While this steel structure reinforcement device extends the service life of steel structure buildings, the threaded rod, being a load-bearing component, is prone to thread damage under stress, affecting secondary use and disassembly, necessitating improvement. Summary of the Invention

[0004] In view of the above-mentioned prior art, the present invention proposes a steel structure reinforcement device.

[0005] The present invention provides a steel structure reinforcement device, including an auxiliary beam, an mounting plate fixed to the end face of the auxiliary beam, a threaded rod and a rotating rod that can move up and down through the auxiliary beam, a thread inside the auxiliary beam that meshes with the threaded rod, a contact plate rotatably connected to the top end of the threaded rod, the rotating rod rotatably connected to the contact plate, a spiral groove on the surface of the rotating rod, a top block on the top surface of the auxiliary beam, and a locking rod that engages with the spiral groove fixed to the side of the top block, the locking rod being slidably connected to the spiral groove;

[0006] A circular block is fixed to the bottom end of the rotating rod. Several slots are formed on the surface of the circular block. A base block is fixed to the bottom surface of the auxiliary beam. A sliding rod is slidably connected to the inside of the base block in a vertical direction. A stop block is fixed to the top of the sliding rod. The bottom of the sliding rod extends to the outside of the base block. An insert block is fixed to the bottom side of the sliding rod and inserted into the slot. A spring is sleeved on the surface of the sliding rod. One end of the spring is fixedly connected to the stop block, and the other end of the spring is fixedly connected to the base block.

[0007] Preferably, the base block is made of austenitic stainless steel in a U-shaped structure.

[0008] Preferably, a throttle is fixed to the bottom end of the threaded rod, a hook and loop fastener A is fixed to the surface of the throttle, a hook and loop fastener B is provided on the surface of the hook and loop fastener A, and a cotton loop is fixed to the surface of the hook and loop fastener B.

[0009] Preferably, the hook and loop fastener A is the male side, and the hook and loop fastener B is the female side.

[0010] Preferably, the cotton ring is made of pure cotton.

[0011] Preferably, the auxiliary beam has an internal cavity, in which several V-shaped reinforcing ribs are fixed in a regular arrangement.

[0012] Preferably, its usage method includes the following steps:

[0013] Step 1: Fix the auxiliary beam with the mounting plate, and reinforce the steel structure by pressing the contact plate against it.

[0014] Step 2: Press the sliding rod into the bottom block to disengage the insert from the slot. Rotate the threaded rod. Since the auxiliary beam has threads inside, the threaded rod moves upward inside the auxiliary beam. The threaded rod drives the contact plate to move upward until the contact plate is in close contact with the steel structure.

[0015] Step 3: Release the slide bar. Under the action of the spring's rebound force, the spring drives the stop block to move downward, the stop block drives the slide bar to move downward, and the slide bar drives the insert block to move downward until the insert block is inserted into the slot, thus restricting the rotation of the rotating rod.

[0016] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention provides a steel structure reinforcement device. The included clamps and spiral grooves effectively support and limit the contact plate, preventing the threaded rod from directly bearing weight and thus preventing damage to the threads, thereby increasing the service life of the threaded rod and enhancing its practicality. The added cotton rings absorb hand sweat, preventing slippage due to sweat, and are easily replaceable, further enhancing its practicality. The further designed inner cavity reduces the weight of the auxiliary beam, while the reinforcing ribs provide reinforcement. This reduces the weight and cost of the auxiliary beam while ensuring overall strength and reliability, facilitating large-scale manufacturing and further enhancing its practicality.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0022] like Figure 1-3 The steel structure reinforcement device shown includes an auxiliary beam 1, with mounting plates 2 fixed at both ends of the auxiliary beam 1. A threaded rod 3 and a rotating rod 4 that can move up and down are installed through the middle of the auxiliary beam 1. The auxiliary beam 1 has threads inside, which mesh with the threaded rod 3. The top of the threaded rod 3 is rotatably connected to a contact plate 21. The top of the rotating rod 4 is also rotatably connected to the contact plate 21. The surface of the rotating rod 4 has a spiral groove 5. A top block 6 is fixed to the top surface of the auxiliary beam 1. A locking rod 7 that engages with the spiral groove 5 is fixed to the side of the top block 6. The locking rod 7 and the spiral groove 5 are slidably connected.

[0023] Furthermore, a circular block 8 is fixed to the bottom end of the rotating rod 4. Several slots 9 are opened on the surface of the circular block 8. A base block 10 is fixed to the bottom surface of the auxiliary beam 1. A sliding rod 11 is slidably connected to the inside of the base block 10 in a vertical direction. A stop block 12 is fixed to the top of the sliding rod 11. The bottom of the sliding rod 11 extends to the outside of the base block 10. An insert block 14 for inserting into the slot 9 is fixed to the bottom side of the sliding rod 11. A spring 13 is sleeved on the surface of the sliding rod 11. The upper end of the spring 13 is fixedly connected to the stop block 12, and the lower end of the spring 13 is fixedly connected to the base block 10.

[0024] The method of using the steel structure reinforcement device includes the following steps:

[0025] Step 1: Fix the auxiliary beam 1 with the mounting plate 2, and reinforce the steel structure by pressing the contact plate 21 against the steel structure;

[0026] Step 2: Press the slide bar 11 upwards into the bottom block 10 to disengage the insert block 14 from the slot 9. Rotate the threaded rod 3. Since the auxiliary beam 1 has threads inside, the threaded rod 3 moves upwards inside the auxiliary beam 1. The threaded rod 3 drives the contact plate 21 to move upwards until the contact plate 21 is in close contact with the steel structure.

[0027] Step 3: Release the slide bar 11. Under the rebound force of the spring 13, the spring 13 drives the stop block 12 to move downward. The stop block 12 drives the slide bar 11 to move downward. The slide bar 11 drives the insert block 14 to move downward until the insert block 14 is inserted into the slot 9. This restricts the rotation of the rotating rod 4, and the locking rod 7 cannot slide in the spiral groove 5. At this time, the locking rod 7 can play a limiting role, which can more firmly limit the contact plate 21 and improve the load-bearing capacity of the contact plate 21. This can prevent the threaded rod 3 from directly bearing the weight, thereby preventing damage to the threads on the threaded rod 3 and improving the service life of the threaded rod 3. It is highly practical.

[0028] In some embodiments, in order to improve the service life of the base block 10, the base block 10 is made of austenitic stainless steel in a U-shaped structure.

[0029] In some embodiments, to facilitate the rotation of the threaded rod 3, a handle 15 is fixed to the bottom end of the threaded rod 3. A hook and loop fastener A 16 is fixed to the surface of the handle 15. A hook and loop fastener B 17 is provided on the surface of the hook and loop fastener A. The hook and loop fastener A is the male side, and the hook and loop fastener B is the female side for easy adhesion. A cotton ring 18 is fixed to the surface of the hook and loop fastener B. The cotton ring 18 is made of pure cotton to improve the sweat absorption effect and prevent the handle 15 from becoming slippery due to sweaty palms. When the cotton ring 18 needs to be removed, simply pull the cotton ring 18. The cotton ring 18 then drives the hook and loop fastener B to move until the hook and loop fastener B leaves the hook and loop fastener A, at which point the cotton ring can be removed. When installing a new cotton ring, simply put the cotton ring on the surface of the hook and loop fastener B and adhere the hook and loop fastener A and the hook and loop fastener B together. At this time, the cotton ring is limited.

[0030] In some embodiments, in order to reduce weight, the auxiliary beam 1 has an inner cavity 19, in which several regularly arranged V-shaped reinforcing ribs 20 are fixed to improve the support strength.

[0031] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structures made using the contents of the present invention specification and drawings, whether directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of the present invention.
