Description

Technical Field

[0001] This utility model belongs to the field of steel structure technology, and specifically relates to a prefabricated steel structure corner connection component. Background Technology

[0002] In construction engineering, the intersection and connection of steel structures form steel structure corners, which are weak points in the load-bearing structure and require reinforcement. In the prior art, Chinese patent CN221702740U discloses a steel structure corner connection structure. This structure has a first steel body on one side, which engages with a second steel body. An L-shaped plate is bolted to the other side of the first steel body, and the L-shaped plate is bolted to the second steel body. A connecting plate is symmetrically arranged between the first and second steel bodies, and an inclined plate is bolted to the side of the connecting plate. In this invention, after the first and second steel bodies are interlocked and fixed by a first T-shaped slot and a first T-shaped block, the sides of the first and second steel bodies can be connected to the L-shaped plate through a first groove and a second groove. The L-shaped plate reinforces the connection between the sides of the first and second steel bodies. This patent utilizes the structural strength of the L-shaped plate itself to support the first and second steel bodies, and the connection angle between the first and second steel bodies is adapted to the shape of the L-shaped plate. With the diversification and complexity of modern architectural design, steel structure corner connections need to adapt to more non-standard angle changes. In this patent, the L-shaped plate is a fixed shape and cannot be adjusted in angle, which is not flexible enough to meet the needs of complex architectural designs. Utility Model Content

[0003] In view of this, the present invention aims to provide a prefabricated steel structure corner connection component that is applicable to construction sites for steel structure corners with various non-standard angles.

[0004] This utility model is achieved through the following technical solution:

[0005] A prefabricated steel structure corner connection component includes a first steel body and a second steel body, with a corner formed at the connection between the two. The prefabricated steel structure corner connection component further includes:

[0006] The first connecting plate has a first fixing surface facing and fixed to the surface of the first steel body, and a first adjusting surface facing away from the first fixing surface, and also has a first connecting end that is hinged to the second connecting plate; a first hinge seat is provided on the first adjusting surface.

[0007] The second connecting plate has a second fixing surface facing and fixed to the surface of the second steel body, and a second adjusting surface facing away from the second fixing surface, and also has a second connecting end that is hinged to the first connecting plate; a second hinge seat is provided on the second adjusting surface;

[0008] A support assembly, the two ends of which are respectively hinged to the first hinge seat and the second hinge seat; the support assembly has a telescopic structure for adjusting the distance between its two ends.

[0009] This device constructs an angle-adjustable support structure to enhance the connection stability at steel structure corners, and can be used as a universal prefabricated component to adapt to various non-standard angle steel structure corner connections. The first and second connecting plates are respectively fixed to the first and second steel bodies. The first and second connecting plates and the support components are hinged in pairs, forming a triangular support structure with the hinge point of the first and second connecting plates, the first hinge seat, and the second hinge seat as vertices. This triangular support structure allows for manual adjustment of the hinge angle and the extension / retraction length of the support components by construction personnel, adapting to various non-standard angles.

[0010] Preferably, the first adjustment surface is provided with a slide rail, the extension direction of which is in line with the extension direction of the first steel body; the first hinge seat has a shape that engages with the slide rail, and the slide rail forms a guiding structure for the sliding trajectory of the hinge seat.

[0011] Because the corner connection structure of this steel structure is assembled using prefabricated components, there may be insufficient adjustment range of the support components. Therefore, other components are used to compensate for the limitations of the support component length adjustment. When the adjustment range of the support components is insufficient to adapt to the installation angle, the position of the first hinge seat can be adjusted to assist in the adaptation.

[0012] Preferably, the support assembly includes a conversion element and a telescopic rod, wherein the conversion element drives the telescopic rod to extend or retract by rotating itself.

[0013] The design of the conversion component and the telescopic pole separates the direction of the telescopic pole's extension and retraction from the direction of the external force during the extension and retraction adjustment process, preventing the force on the telescopic pole under load from directly adjusting its extension and retraction length, thus improving structural stability. On the other hand, construction personnel can precisely control the length extension of the telescopic pole by rotating the conversion component.

[0014] Preferably, the telescopic structure includes a telescopic rod and a rigid sleeve fitted over the outside of the telescopic rod; the telescopic structure has at least a length state in which the telescopic rod is fully retracted into the rigid sleeve.

[0015] When the telescopic rod is fully retracted into the rigid sleeve, the rigid sleeve and the telescopic rod together provide support for the corner structure, which not only disperses the force, but also reduces the torque by shortening the lever arm, and also reduces the space occupied at the corner.

[0016] Preferably, the prefabricated steel structure corner connection component further includes a fixing component; the fixing component includes a fixing piece disposed on the edge of the first connecting plate and multiple sets of fasteners, the fixing piece having a main positioning hole and a secondary positioning hole spaced apart, one set of fasteners passing through the main positioning hole and the first connecting plate and fixing the fixing piece and the first connecting plate to the first steel body, and another set of fasteners passing through the secondary positioning hole and fixing the fixing piece to the first steel body.

[0017] The retaining plate acts as a gasket, enhancing the connection stability of the fasteners to the first steel body and the first connecting plate. Each retaining plate is secured by two positioning holes to prevent it from slipping around the fastener group if a single fastener becomes loose.

[0018] Preferably, the prefabricated steel structure corner connection component further includes a support rod; the two ends of the support rod are respectively fixed to the first steel body and the second steel body.

[0019] The support rod directly forms a triangular support structure with the first and second steel bodies, sharing the force of the support components.

[0020] Preferably, the fixing piece includes a first fixing piece and a second fixing piece arranged in pairs on the same side of the support assembly; the steel structure corner connection prefabricated component also includes a support rod, one end of which is fixed to the first steel body through a fastener group and the secondary positioning hole of the first fixing piece, and the other end of which is fixed to the second steel body through a fastener group and the secondary positioning hole of the second fixing piece.

[0021] The support rod is fixed by making full use of the secondary positioning holes. At this time, the support rod is located at the edge of the connecting plate, while the hinge seat for fixing the support assembly is located inside the connecting plate. Therefore, the support rod is located outside the support assembly and has a structural protection function.

[0022] Preferably, the surface of the first steel body is provided with an installation groove that matches the shape and size of the fixing piece, and the fixing piece is embedded in the installation groove and fixed to the first steel body by a fastener assembly.

[0023] The mounting slot not only indicates the installation position of the fixing plate, but also locks the fixing plate in place to prevent it from loosening or shifting.

[0024] Preferably, the first steel body and the second steel body are connected by a splicing assembly; the splicing assembly includes a plug and a slot located on different steel bodies, the plug and the slot having mutually compatible shapes; the plug is slidably inserted into the slot along the splicing direction, and the slot is provided with a limiting surface that restricts the plug from sliding in directions other than the splicing direction.

[0025] To further improve the ease of assembly of prefabricated components on the construction site, the steel bodies are joined together using a plug-in method. A limiting surface restricts the movement of the plug within the slot, ensuring that the plug can only slide along the joining direction and preventing it from detaching from the slot in other directions.

[0026] Preferably, the assembly further includes an assembly fastener connecting the insert and the slot; the insertion direction of the assembly fastener intersects with the assembly direction of the insert and the slot.

[0027] The position of the insert in the slot is further restricted by the fasteners, preventing the insert from coming out of the slot in the opposite direction of the splicing.

[0028] This invention features multiple adjustable components to adapt to various non-standard corner construction scenarios. Furthermore, a limiting structure ensures flexible adjustment while enhancing device stability, overcoming potential problems such as loosening, slippage, and stress concentration. The steel components are connected via plug-in assembly components, with cross-positioning achieved through limiting surfaces and fasteners, simplifying on-site assembly. The overall structure combines flexibility, long-term reliability, and ease of construction. Attached Figure Description

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will be able to implement the present invention based on these descriptions. Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Example

[0042] In this embodiment, both the first steel body 1 and the second steel body 2 are square steel, and they are connected to form a steel structure corner connection structure. When the connection angle between the first steel body 1 and the second steel body 2 is a right angle, it is called a "standard angle"; conversely, when the connection angle is not a right angle, it is called a "non-standard angle". This embodiment aims to provide a steel structure corner connection structure suitable for non-standard angles, and it can be assembled to accommodate different angles through prefabrication.

[0043] Since the corner formed by the connection between the first steel body 1 and the second steel body 2 is a non-standard angle, the connecting prefabricated component should be able to be adjusted according to the actual connection angle between the first steel body 1 and the second steel body 2.

[0044] Please see Figure 1 and Figure 3 The steel structure corner connection structure includes a first connecting plate 110 fixed to a first steel body 1 and a second connecting plate 210 fixed to a second steel body 2. The first connecting plate 110 has a first fixing surface facing the surface of the first steel body 1 and a first adjusting surface facing away from the first fixing surface, and also has a first connecting end 120 hinged to the second connecting plate 210; a first hinge seat 130 is provided on the first adjusting surface away from the first connecting end 120; the second connecting plate 210 has a second fixing surface facing the surface of the second steel body 2 and a second adjusting surface facing away from the second fixing surface, and also has a second connecting end 220 hinged to the first connecting plate 110; a second hinge seat 230 is provided on the second adjusting surface away from the second connecting end 220; the support assembly 3 includes a telescopic rod 310 with adjustable length. The two ends of the support assembly 3 are respectively hinged to the two hinge seats on the two connecting plates; the support assembly 3 has a telescopic structure for adjusting the distance between its two ends.

[0045] The support component 3, the first connecting plate 110, and the second connecting plate 210 form a triangle with the hinge point between the first connecting end 120 and the second connecting end 220, the first hinge seat 130, and the second hinge seat 230 as vertices, providing support for the corner connection between the first steel body 1 and the second steel body 2. This triangular support structure can adapt to various non-standard angles by changing the hinge angle and the shape of the support component 3 through extension and retraction; once the hinge angle and the length of the support component 3 are determined, the structure has stability.

[0046] Since the corner connection structure of this steel structure is assembled using prefabricated components, there may be a situation where the adjustment range of support component 3 is insufficient. Therefore, this is compensated for by increasing the adjustability of other components.

[0047] Please see Figure 3 The first adjustment surface is provided with a slide rail 140, and the extension direction of the slide rail 140 is in line with the extension direction of the first steel body 1; the first hinge seat 130 has a shape that engages with the slide rail 140, and the slide rail 140 forms a guiding structure for the sliding trajectory of the first hinge seat 130.

[0048] When the adjustment range of the support component 3 is insufficient to accommodate the installation angle, the position of the first hinge seat 130 can be adjusted to assist in the adaptation. Furthermore, in the pre-tightening method two described later, the slide rail 140 also serves to stabilize the structure.

[0049] In the above structure, the direction of extension and retraction of the support component 3 is the direction of the support force. The telescopic rod 310 may break or retract. Therefore, the telescopic structure is optimized to reduce the risk of breakage and retraction.

[0050] Please see Figure 3 The support component 3 includes a conversion element 320 and a telescopic rod 310. The conversion element 320 drives the telescopic rod 310 to extend or retract through its own rotation. In this embodiment, the conversion element 320 is an internally threaded sleeve, and the telescopic rod 310 is a threaded rod. When the internally threaded sleeve rotates, the threaded rod extends or retracts. In some embodiments, a threaded rod is connected to each end of the internally threaded sleeve, and the two threaded rods extend or retract synchronously with the rotation of the internally threaded sleeve. In some embodiments, the conversion element 320 can be wrapped with an anti-slip pad to facilitate rotation by construction personnel.

[0051] The design of the conversion component 320 and the telescopic rod 310 separates the actual movement direction of the telescopic rod 310 from the direction of the external force during the telescopic adjustment process, thus avoiding direct adjustment of its telescopic length by the load-bearing force on the telescopic rod 310 and improving structural stability. On the other hand, construction personnel can precisely control the length expansion of the telescopic rod 310 by rotating the conversion component 320.

[0052] Please see Figure 3 The telescopic structure includes a telescopic rod 310 and a rigid sleeve 330 sleeved outside the telescopic rod 310; the telescopic structure has at least a length state in which the telescopic rod 310 is fully retracted into the rigid sleeve 330.

[0053] When the telescopic rod 310 is fully retracted into the rigid sleeve 330, the rigid sleeve 330 and the telescopic rod 310 simultaneously provide support for the corner structure, which not only disperses the force, but also reduces the torque by shortening the lever arm, and also reduces the space occupied at the corner.

[0054] In a preferred embodiment, the rigid sleeve 330 and the conversion element 320 can correspond to the same solid part, namely the internal threaded sleeve, thereby simplifying the structure.

[0055] Further strengthen the connection strength between the first connecting plate 110, the second connecting plate 210 and the steel body.

[0056] Please see Figure 2 and Figure 4 This embodiment also includes a fixing component 4; the fixing component 4 includes a first fixing piece 410 and multiple sets of fasteners. The fixing piece has a main positioning hole 411 and a secondary positioning hole 412 spaced apart. One set of fasteners passes through the main positioning hole 411 and the first connecting plate 110 and fixes them to the first steel body 1. Another set of fasteners passes through the secondary positioning hole 412 and fixes it to the first steel body 1.

[0057] The fixing plate primarily functions as a gasket, enhancing the connection stability of the fastener assembly between the first steel body 1 and the first connecting plate 110. Furthermore, the fixing plate is provided with a main positioning hole 411 and a secondary positioning hole 412, meaning that a single fixing plate is secured by a double fastener assembly, preventing slippage or displacement of the fixing plate should one fastener become loose.

[0058] The supporting structure between the first steel body 1 and the second steel body 2 is supplemented to share and reduce the workload of the supporting component 3.

[0059] Please see Figure 1 and Figure 4The prefabricated steel structure corner connection component also includes a support rod 5; both ends of the support rod 5 are fixed to the first steel body 1 and the second steel body 2, respectively. In a preferred embodiment, the support rod 5 is fixed by fully utilizing the secondary positioning hole 412. At this time, the fixing pieces include a first fixing piece 410 and a second fixing piece 420 arranged in pairs on the same side of the support assembly 3; one end of the support rod 5 is fixed to the first steel body 1 by a fastener group and the secondary positioning hole 412 of the first fixing piece 410, and the other end is fixed to the second steel body 2 by a fastener group and the secondary positioning hole 412 of the second fixing piece 420. Furthermore, the fixing pieces of a single steel body are arranged in pairs on the left and right sides of the support assembly 3, so that the steel body is subjected to balanced and stable forces.

[0060] The support rod 5 first forms a triangular structure directly with the first steel body 1 and the second steel body 2, sharing the force of the support assembly 3 and improving structural stability. When the support rod 5 is fixed through the secondary positioning hole 412, the position of the support rod 5 is at the edge of the connecting plate, while the hinge seat for fixing the support assembly 3 is located inside the connecting plate. Therefore, the support rod 5 is located outside the support assembly 3 and has a structural protection function.

[0061] Considering the on-site installation requirements, prefabricated components should have guidance and prompting functions so that construction workers can install them directly without having to perform measurements and calculations.

[0062] Please see Figure 2 and Figure 4 Both the first steel body 1 and the second steel body 2 have mounting grooves 6 on their surfaces. The mounting grooves 6 are adapted to the shape and size of the fixing piece, and can just accommodate the fixing piece. The fixing piece is embedded in the mounting groove 6 and fixed to the steel body by a set of fasteners. The mounting groove 6 can both indicate the installation position of the fixing piece and lock the fixing piece to prevent loosening or displacement.

[0063] Please see Figure 2The first steel body 1 and the second steel body 2 are connected by a splicing assembly 7. The splicing assembly 7 includes an insert 710 and a slot 720 located on different steel bodies, and the insert 710 and the slot 720 have mutually adaptable shapes. The insert 710 slides into the slot 720 along the splicing direction, and the slot 720 is provided with a limiting surface 721 to restrict the sliding of the insert 710 in directions other than the splicing direction. Further, the splicing assembly 7 also includes a splicing fastener 730 connecting the insert 710 and the slot 720; the insertion direction of the splicing fastener 730 intersects with the splicing direction of the insert 710 and the slot 720. The steel bodies are spliced ​​using an insert-fit method. The limiting surface 721 restricts the range of motion of the insert 710 in the slot 720, and the insert 710 can only slide along the splicing direction, preventing it from disengaging from other directions into the slot 720. The fastener 730 further restricts the position of the insert 710 in the slot 720, preventing the insert 710 from coming out of the slot 720 in the opposite direction of the assembly.

[0064] Based on the coordination of various structures, this device has two pre-tightening methods: Method 1 is tightening by extending the telescopic rod 310, and Method 2 is tightening by retracting the telescopic rod 310. The specific operation instructions for Method 2 are as follows:

[0065] 1. Place the first connecting plate 110 and the second connecting plate 210, which are hinged to each other, at the corner formed by the connection of the first steel body 1 and the second steel body 2. The first connecting plate 110 is attached to the surface of the first steel body 1, and the second connecting plate 210 is attached to the surface of the second steel body 2. The first connecting end 120 and the second connecting end 220 face the corner.

[0066] 2. Place a first fixing plate 410 on each of the left and right sides of the first connecting plate 110. Fasteners pass through the main positioning hole 411 on the fixing plate and the first connecting plate 110, and fix the two to the first steel body 1. Correspondingly, place a second fixing plate 420 on each of the left and right sides of the second connecting plate 210. Fasteners pass through the main positioning hole 411 on the fixing plate and the second connecting plate 210, and fix the two to the second steel body 2.

[0067] 3. Align both ends of the support rod 5 with the secondary positioning holes 412 on the first fixing plate 410 and the second fixing plate 420 respectively, and fix them with fasteners;

[0068] 4. The first hinge seat 130 is sleeved onto the slide rail 140 on the surface of the first connecting plate 110, and the second connecting plate 210 is sleeved onto the slide rail 140 on the surface of the second hinge seat 230.

[0069] 5. Rotating the anti-slip pad causes the internal threaded sleeve to rotate, and the internal threaded sleeve causes the telescopic rods 310 on both sides to gradually retract into the internal threaded sleeve; as the telescopic rods 310 retract, the support assembly 3 shortens as a whole, and the two hinge seats slide towards the connection end along the slide rail 140.

[0070] 6. When the telescopic rod 310 is fully retracted into the internal threaded sleeve, it completes the support for the first steel body 1 and the second steel body 2.
