Description

Technical Field

[0001] This invention relates to the field of chemical plant building technology, and more specifically to a building structure reinforcement device. Background Technology

[0002] In the chemical industry, production plants and equipment support structures are often subjected to complex environments such as high temperatures, corrosive media, and vibration loads for extended periods. Their structural safety is crucial for ensuring continuous production and preventing secondary disasters such as leaks and explosions. Due to early, outdated design standards for chemical plant buildings, or increased equipment loads caused by changes in production processes, many existing plant buildings' load-bearing columns, beams, frame joints, and other key components no longer meet current standards in terms of material strength, connection reliability, and overall stability. Furthermore, mechanical vibrations generated during the operation of chemical plants, pipeline thermal stress, and potential external forces such as earthquakes and wind loads can easily cause structural cracking, tilting, or even partial collapse, seriously threatening personnel lives and the safety of the surrounding environment. Therefore, efficient and reliable reinforcement and renovation of chemical plant buildings has become an urgent need for the safety management of chemical enterprises.

[0003] Currently, common methods for strengthening building structures mainly include increasing the cross-section, external steel cladding, carbon fiber bonding, and adding support systems. However, these traditional methods have revealed significant limitations in chemical environments. Increasing the cross-section requires pouring concrete onto the surface of the existing components, resulting in a long construction period, a large amount of wet work, and safety hazards in flammable and explosive environments. While external steel cladding can improve load-bearing capacity, joint treatment is complex, and welding or bolting connections can easily generate sparks, making it unsuitable for explosion-proof areas. Furthermore, the interface between the steel and concrete is prone to stress hysteresis and corrosion in corrosive atmospheres. While carbon fiber bonding is convenient, it requires stringent substrate preparation; acidic and alkaline media in chemical environments accelerate the aging of carbon fiber adhesives, making long-term reliability difficult to guarantee. More importantly, most of these methods are passive reinforcements, lacking active adjustment and anti-sway functions. When a chemical plant experiences cyclic displacement due to equipment vibration or wind loads, relative displacement or even micro-gaps can easily occur between the reinforcement layer and the original structure, leading to a decrease in reinforcement effectiveness or even failure.

[0004] Existing technologies also disclose some specially designed building structure reinforcement devices. For example, Chinese patent CN216840761U discloses a building structure reinforcement device that mainly uses a limiting rod to facilitate the adjustment of the distance between two mounting plates, making the force more uniform and improving the convenience and stability of adjustment. However, this device still has obvious defects when practically applied to chemical plants: when a small gap is generated between the reinforcement device and the building structure surface due to installation tolerances, concrete shrinkage, or long-term vibration, the structure will wobble slightly. This wobble will aggravate fatigue damage to the connection nodes in a chemical environment and may cause the reinforcement device to lose its pre-tightening force, thereby weakening the overall reinforcement effect. Especially in plants that bear large reactors, compressors, and other vibrating equipment, the dynamic response caused by the gap will significantly reduce the reliability of the reinforcement. Therefore, there is an urgent need to provide a building structure reinforcement device that can eliminate installation gaps and has an active anti-sway function to adapt to the complex and variable stress environment of chemical plants. Summary of the Invention

[0005] To address the issue that dynamic response caused by gaps can significantly reduce the reliability of reinforcement in factories that support vibrating equipment such as large reactors and compressors; This invention provides a building structure reinforcement device, including a reinforcement base and a reinforcement ring. The upper surface of the reinforcement base is threaded with four stabilizing bolts in a rectangular array. Multiple first mounting plates are fixedly mounted on the upper surface of the reinforcement base in a rectangular array. A through-hole is formed at the top of the sidewall of each first mounting plate. A limiting pin is engaged with the top of the sidewall of the first mounting plate through the through-hole. A limiting ring is bonded inside the through-hole. A reinforcement plate is movably sleeved on the outer surface of the limiting pin. Multiple second mounting plates are fixedly mounted on the outer surface of the reinforcement ring in a circular array. A connecting rod is fixedly mounted at the top of the sidewall of each second mounting plate. An anti-sway component is fixedly mounted inside the reinforcement ring.

[0006] As a preferred embodiment, the bottom end of the stabilizing bolt is adapted to a stabilizing nut embedded in the ground, and the cross-sectional area of ​​the stabilizing bolt is larger than the cross-sectional area of ​​the mounting through hole.

[0007] As a preferred embodiment, the number of mounting through holes is several, and the several mounting through holes are equally divided into four groups, and the number of limiting rings is four.

[0008] As a preferred embodiment, the front side of the reinforcing plate has two connecting through holes that are symmetrically oriented along the center. The interior of the two connecting through holes is adapted to the outer surface of the limiting pin and the outer surface of the connecting rod, respectively.

[0009] As a preferred embodiment, the interior of the limiting ring is adapted to one end of the limiting pin, the limiting ring is made of rubber, and the cross-sectional area of ​​the limiting ring is the same as the cross-sectional area of ​​the connecting through hole.

[0010] As a preferred embodiment, the anti-sway assembly includes a mounting ring and connecting bases. The mounting ring has four connecting bases detachably mounted in a circular array inside. The outer surface of the mounting ring is connected to the interior of the reinforcing ring.

[0011] As a preferred embodiment, an electric telescopic rod is detachably installed on the back of the connecting base, and a fastening pad is fixedly installed at the input end of the electric telescopic rod. The surface of the fastening pad is in contact with the outer surface of the building structure, and the fastening pad is made of rubber.

[0012] The beneficial effects of this invention are as follows: 1. This invention, by setting an anti-sway component, allows the reinforcement ring to be fitted onto the outer surface of the building structure to be reinforced. Then, the bottom end of the building structure to be reinforced is brought into contact with the center of the upper surface of the reinforcement base. Next, the reinforcement plate is connected to the first mounting plate. At this time, the electric telescopic rod inside the anti-sway component is activated. The electric telescopic rod will then drive the fastening pad to move towards the outer surface of the building structure to be reinforced until the surface of the fastening pad is in contact with the outer surface of the building structure to be reinforced. This will fix the building structure to be reinforced again, thereby preventing the building structure to be reinforced from shaking due to gaps between it and the reinforcement ring, thus enhancing the practicality of the device. 2. This invention, by setting up a reinforcing plate, a first mounting plate, mounting through holes, a limiting pin, and a limiting ring, allows for easy connection between the reinforcing ring and the reinforcing base. Simply place the reinforcing ring onto the outer surface of the building structure to be reinforced, then bring the bottom end of the building structure in contact with the center of the upper surface of the reinforcing base. Next, place the bottom end of the reinforcing plate at the center of the two sets of first mounting plates. Then, one end of the limiting pin is engaged with the inside of the limiting ring through the mounting through hole and the connecting through hole, thus connecting the reinforcing base and the reinforcing ring. Because the limiting pin is engaged inside the limiting ring, this method saves assembly time compared to bolt connections, thereby improving the assembly efficiency of the device.

[0015] To illustrate the features of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Example 1: Please see Figures 1 to 3 A building structure reinforcement device includes a reinforcement base 1 and a reinforcement ring 8. Four stabilizing bolts 2 are threaded in a rectangular array on the upper surface of the reinforcement base 1. Multiple first mounting plates 3 are fixedly mounted in a rectangular array on the upper surface of the reinforcement base 1. A through-hole 4 is formed at the top of the side wall of each first mounting plate 3. A limiting pin 5 is engaged through the through-hole 4 at the top of the side wall of each first mounting plate 3. A limiting ring 6 is bonded inside the through-hole 4. A reinforcement plate 7 is movably sleeved on the outer surface of the limiting pin 5. Multiple second mounting plates 9 are fixedly mounted in a circular array on the outer surface of the reinforcement ring 8. A connecting rod 10 is fixedly mounted at the top of the side wall of each second mounting plate 9. The reinforcement ring 8... An anti-sway component 11 is fixedly installed inside. The bottom end of the stabilizing bolt 2 is adapted to the stabilizing nut embedded in the ground. The cross-sectional area of ​​the stabilizing bolt 2 is larger than the cross-sectional area of ​​the mounting through hole 4. There are several mounting through holes 4, which are divided into four groups. There are four limiting rings 6. The front of the reinforcing plate 7 is symmetrically opened with two connecting through holes along the center. The interior of the two connecting through holes is adapted to the outer surface of the limiting pin 5 and the outer surface of the connecting rod 10, respectively. The interior of the limiting ring 6 is adapted to one end of the limiting pin 5. The limiting ring 6 is made of rubber. The cross-sectional area of ​​the limiting ring 6 is the same as the cross-sectional area of ​​the connecting through hole.

[0017] By matching the bottom end of the stabilizing bolt 2 with the inside of the stabilizing nut embedded in the ground, it is possible to ensure the stability of the reinforcement device and thus better reinforce the building structure.

[0018] Example 2: Please see Figure 4The anti-sway component 11 includes a mounting ring 111 and a connecting base 112. The mounting ring 111 has four connecting bases 112 detachably mounted in a circular array inside. The outer surface of the mounting ring 111 is connected to the inside of the reinforcing ring 8. An electric telescopic rod 113 is detachably mounted on the back of the connecting base 112. A fastening pad 114 is fixedly mounted on the input end of the electric telescopic rod 113. The surface of the fastening pad 114 is in contact with the outer surface of the building structure. The fastening pad 114 is made of rubber.

[0019] By making the fastening pad 114 a rubber component, it is to help ensure the quality of the building structure when fixing it. At the same time, the fastening pad 114 will also increase the friction between the fastening pad and the building structure, thereby preventing the building structure from shaking.

[0020] Among them, the electric telescopic pole 113 is a Royal brand, SXTL model.

[0021] The working process of this invention is as follows: In order to prevent the reinforced building structure from shaking during operation, the reinforcement device is equipped with an anti-sway component 11. When the reinforcement ring 8 is fitted onto the outer surface of the building structure to be reinforced, the bottom end of the building structure to be reinforced is then brought into contact with the center of the upper surface of the reinforcement base 1. Next, the reinforcement plate 7 is connected to the first mounting plate 3. At this time, the electric telescopic rod 113 inside the anti-sway component 11 is activated. The electric telescopic rod 113 will then drive the fastening pad 114 to move towards the outer surface of the building structure to be reinforced until the surface of the fastening pad 114 is in contact with the outer surface of the building structure to be reinforced, thereby fixing the building structure to be reinforced again. This avoids the phenomenon of shaking caused by gaps between the building structure to be reinforced and the reinforcement ring 8, thus enhancing the practicality of the device.

[0022] In the above scheme, the reinforcement device is equipped with a reinforcement plate 7, a first mounting plate 3, a mounting through hole 4, a limiting pin 5, and a limiting ring 6 to facilitate the connection between the reinforcement ring 8 and the reinforcement base 1. When it is necessary to connect the reinforcement ring 8 and the reinforcement base 1, the reinforcement ring 8 is simply fitted onto the outer surface of the building structure to be reinforced, and then the bottom end of the building structure to be reinforced is brought into contact with the center of the upper surface of the reinforcement base 1. Then, the bottom end of the reinforcement plate 7 is placed at the center of the two sets of first mounting plates 3. Next, one end of the limiting pin 5 is respectively engaged with the inside of the limiting ring 6 through the mounting through hole 4 and the connecting through hole, thus connecting the reinforcement base 1 and the reinforcement ring 8. Because the limiting pin 5 is engaged with the inside of the limiting ring 6, this method saves more assembly time than using bolts, thereby improving the assembly efficiency of the device.
