Description

Technical Field

[0001] This utility model belongs to the field of building engineering, and specifically relates to a fixing device for the firewall frame of a converter station. Background Technology

[0002] With social progress and the development of power technology, the construction of converter stations has become an indispensable and crucial part of substation engineering. Firewalls are important concrete structures in substation projects. Using fair-faced concrete firewalls not only improves the structural strength and safety of the firewalls, but also enhances the overall image of the substation project due to their superior aesthetic quality. However, firewalls face challenges due to their high construction height, the requirement for one-time molding, stringent process requirements, the inability to create openings in the surface, and the lack of a suitable location for securing the scaffolding during construction. Conventional scaffolding fixation involves pre-embedding steel pipes within the concrete structure for connection, but this method is unsuitable for firewall construction.

[0003] Based on this, the present invention proposes a fixing device for the firewall frame of a converter station. Utility Model Content

[0004] To address the aforementioned problems in the prior art, namely the lack of a fixed location for the firewall construction frame and the inapplicability of the pre-embedded steel pipe method, this utility model provides a firewall frame fixing device for converter stations, comprising: fastening screws, fixing plates, steel pipes, and fasteners;

[0005] One end of the fastening screw is fixedly connected to one end of the steel pipe;

[0006] The other end of the fastening screw passes through a pre-set hole in the firewall and is fixed to the firewall by the fixing plate and fasteners;

[0007] The other end of the steel pipe is detachably connected to the construction frame via the fastener.

[0008] Furthermore, the fastening screw is a through-thread screw.

[0009] Furthermore, the fastener is a nut, and the fastening screw is fixed to the firewall by the fixing plate and the nut.

[0010] Furthermore, the fixing plate is a steel plate with a circular hole, through which the fastening screw passes and is fixed by fasteners.

[0011] Furthermore, the diameter of the circular hole matches the diameter of the fastening screw.

[0012] Furthermore, the steel pipe and the fastening screw are fixedly connected by welding.

[0013] Furthermore, the fastener is a scaffolding fastener.

[0014] Furthermore, the fixing plate consists of two pieces, located on both sides of the firewall, which together clamp the firewall.

[0015] The beneficial effects of this utility model are:

[0016] This invention reliably fixes the firewall to the construction scaffolding by combining the high-strength threaded rod with the steel pipe. It allows for prefabrication based on actual site conditions, securing the high-strength threaded rod to the firewall using fixing plates and nuts, and reliably connecting the steel pipe to the construction scaffolding using fasteners. This device ensures the construction scaffolding is unaffected by loads, concrete pouring, or vibration, thus guaranteeing the strength and safety of the scaffolding, reducing safety hazards, simplifying on-site installation, facilitating material sourcing, and reducing construction costs while ensuring schedule, quality, and safety, thereby improving economic efficiency.

[0019] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, the first embodiment of this utility model provides a converter station firewall frame fixing device, including: fastening screw 1, fixing plate 2, steel pipe 3 and fastener 4;

[0022] One end of the fastening screw 1 is fixedly connected to one end of the steel pipe 3;

[0023] The other end of the fastening screw 1 passes through a pre-set hole in the firewall 5 and is fixed to the firewall 5 by the fixing plate 2 and fasteners;

[0024] The other end of the steel pipe 3 is detachably connected to the construction frame 6 via the fastener 4.

[0025] The installation and usage process is as follows:

[0026] Tighten the matching fastener at one threaded end of the screw rod, and fix one end of the screw rod 1 to one end of a section of steel pipe 3 by welding to form a rigid connection. Place a fixing plate 2 on each side of the firewall 5, and pass the other end of the screw rod 1 through the fixing plate 2 and pre-drilled holes in the firewall 5. Then tighten another fastener at the other threaded end of the screw rod 1, and rotate the two fasteners to apply clamping force to the fixing plates on both sides, thus firmly locking the entire connection to the firewall. At this point, the firewall fixing part of the device is complete. Next, detachably connect the free end of the steel pipe 3 to the uprights or crossbars of the external construction frame 6 using a standard scaffolding coupler 4, thereby reliably fixing the construction frame to the firewall and providing stable and safe support for subsequent high-altitude operations.

[0027] This utility model utilizes the firewall itself as a load-bearing structure. A clamping system consisting of a fastening screw rod 1, a fixing plate 2, and fasteners transfers the force to the wall, perfectly solving the core problem of the inability to create openings or embed parts on the surface of fair-faced concrete firewalls, thus preventing the scaffold from being fixed in place. The entire device uses conventional building materials and standard parts, such as ordinary steel pipes, screw rods, and scaffold couplers, making the materials readily available, easy to process, and inexpensive. Its installation process requires no complex machinery or specialized trades; ordinary workers can operate it, greatly simplifying the construction process and shortening the construction period. Ultimately, this device ensures the strength and stability of the construction scaffold under various loads such as concrete pouring, vibration, and personnel operation, significantly reducing the safety risks of working at heights, while avoiding leaving permanent embedded parts on the high-quality fair-faced concrete surface, thus balancing structural safety and aesthetic quality.

[0028] As a further explanation of this utility model, the fastening screw 1 is a through screw, the fastener is a nut 101, and the fastening screw 1 is fixed to the firewall 5 by the fixing plate 2 and the nut 101.

[0029] In this embodiment, the fastening screw 1 is a through-thread screw, meaning the entire screw is machined with continuous and complete external threads. This structural design brings significant convenience and reliability in actual construction. During installation, the construction personnel can pre-screw a matching nut 101 into the end of the screw that does not need to penetrate the wall. After the screw passes through the hole in the firewall 5 and the fixing plates 2 on both sides, another nut 101 is screwed in. By simply tightening the nuts on both the inner and outer sides of the wall, the mechanical self-locking property of the threads can be used to firmly clamp the connecting device onto the firewall.

[0030] The key feature of the through-thread screw is its full-length thread structure, which allows the nut to be tightened at any position on the screw body. This provides significant tolerance and flexibility for on-site installation, effectively accommodating potential thickness variations in the wall and ensuring a secure clamping fixation under any circumstances. This invention greatly simplifies the installation and commissioning process, improving construction efficiency. By providing a larger threaded contact area and adjustable clamping force, it significantly enhances the strength and reliability of the connection, thereby ensuring the stability and safety of the entire frame support system.

[0031] As a further explanation of this utility model, the fixing plate 2 is a steel plate with a circular hole. The fastening screw 1 passes through the circular hole and is fixed by fasteners. The diameter of the circular hole matches the diameter of the fastening screw 1.

[0032] In this embodiment, the fixing plate 2 is made of steel plate, and its core structure is a circular hole in the center of the plate. During implementation, the pre-machined fixing plate 2 is fitted onto the fastening screw 1 that has already passed through the firewall 5, ensuring the screw passes precisely through the circular hole. The diameter of this circular hole is precisely calculated and machined, and its size is in close dynamic fit with the diameter of the selected fastening screw 1, allowing the screw to pass smoothly while minimizing the gap between them, providing good alignment for subsequent tightening. Finally, by tightening the nut 101 and other fasteners at the threaded end of the screw, the fixing plate 2 is firmly pressed against the surface of the firewall 5.

[0033] The steel fixing plate 2 provides extremely high compressive strength and rigidity, effectively resisting the high-pressure preload generated during nut tightening and preventing deformation and failure. Its circular holes match the fastening screw 1, ensuring the center of force always coincides with the screw axis, avoiding eccentric loads or installation swaying that might occur due to excessive clearance, thus enhancing the stability and safety of the connection. This structure ultimately distributes the load transmitted from the construction frame evenly across the concrete surface of the firewall through the large-area contact of the steel plates, preventing stress concentration and localized damage to the precious fair-faced concrete wall, achieving the goal of providing a strong connection point while protecting the integrity of the wall.

[0034] As a further explanation of this utility model, the fastener 4 is a scaffolding fastener.

[0035] In this embodiment, the fastener 4 is a standard scaffolding fastener widely used in engineering, such as common right-angle fasteners, swivel fasteners, or butt fasteners. During implementation, the operator places the free end of the steel pipe 3, which is already fixedly connected to the firewall 5, against the predetermined connection point of the upright or horizontal bar of the construction frame 6. Then, the standard scaffolding fastener is taken out, and its clamping component is accurately wrapped around the intersection or contact point between the steel pipe 3 and the frame member. The bolt and nut mechanism on the fastener is then tightened with a wrench. By continuously tightening the bolts, the clamping component of the fastener continuously contracts, generating a huge frictional force, ultimately tightly binding the steel pipe 3 and the member of the construction frame 6 together, forming a rigid and reliable connection node.

[0036] Its greatest advantage lies in its seamless compatibility and rapid connection with existing construction scaffolding systems, eliminating the need for customized special components, greatly simplifying preparation work and reducing procurement costs. Its mechanical fastening method is safe and reliable, ensuring sufficient load-bearing capacity, and the installation and disassembly process is extremely simple and quick. Ordinary workers can operate it proficiently without training, greatly improving work efficiency and facilitating rapid adjustment and reuse during construction. This connection method is detachable; after the completion of the construction task, the fixing device can be easily removed from the scaffolding. All components, including fasteners, can be recycled for use in other projects, achieving material recycling and conforming to the concept of green construction.

[0037] As a further explanation of this utility model, the fixing plate 2 is provided in two pieces, which are respectively located on both sides of the firewall 5 and together clamp the firewall 5.

[0038] In this embodiment, the fixing plate 2 adopts a clamp-type structure, consisting of two identical steel plates. During implementation, the construction worker first passes the fastening screw 1 through a pre-drilled hole in the firewall 5. Then, on one side of the wall, for example the outer side, the first fixing plate 2 is aligned with its circular hole and fitted onto the exposed fastening screw 1. Next, on the other side of the wall, the same operation is performed, fitting the second fixing plate 2 onto the screw, so that the two steel plates are tightly against the two outer surfaces of the firewall 5. Finally, matching nuts 101 are screwed onto the threaded ends of the screw located on the outer sides of the two fixing plates, and a wrench is used to gradually tighten the nuts on both sides in a diagonal alternating sequence. As the nuts are tightened, the two fixing plates are pulled closer together, thus acting like the two arms of a "clamp," jointly and evenly clamping the firewall wall in the middle, and the resulting huge static friction force firmly locks the entire device in the preset position.

[0039] The fixing plates on both sides evenly distribute the tensile force borne by the fastening screws and the load transmitted from the construction frame to the concrete surface on both sides of the firewall through a large-area contact, greatly avoiding stress concentration and effectively protecting the fair-faced concrete wall from local crushing or damage. Compared with the traditional method of adding a large shim to a single steel plate on one side, this symmetrical structure completely eliminates the risk of the wall being subjected to bending or splitting stress, significantly enhances the stability and safety of the connection, and ensures that the entire support system maintains extremely high reliability under complex working conditions such as high-altitude operations and concrete pouring and vibration.
