Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a bent node connection structure for floor decking. Background Technology

[0002] In modern building structures, floor decking, as a common composite floor component, is widely used in the floor slabs and roofs of industrial and civil buildings. It achieves load transfer and structural support through connections with load-bearing components such as steel beams. The joint connection structure of floor decking is a crucial link in ensuring the overall structural stability, safety, and construction efficiency, especially in scenarios requiring bent connections (such as floor corners and junctions between high and low spans). The rationality of the joint connections directly affects the structural performance and service life of the building.

[0003] In existing technologies, the bent joint connection between floor decking and steel beams typically employs direct lap joints or simple supports. Relying solely on the localized contact stress on the side of the steel beam makes the floor decking susceptible to deformation, loosening, or even detachment due to load concentration, severely impacting structural safety. Summary of the Invention

[0004] The purpose of this invention is to provide a bent node connection structure for floor decking to solve the problems mentioned in the background art.

[0005] The present invention provides a technical solution: a floor decking bending node connection structure, comprising: Steel beams are used to connect the first floor deck and the second floor deck. One floor deck overlaps the top of the steel beam, and the other floor deck overlaps the side of the steel beam. Transition ribs connect the first floor deck and the second floor deck. The auxiliary support components include stiffening plates and continuous plates. The stiffening plates are fixed to the side of the steel beam, and the continuous plates are fixed to the top of the stiffening plates. There is a space between the continuous plates and the top of the steel beam. The floor decking that overlaps the side of the steel beam is connected to the continuous plates.

[0006] The beneficial effects of the above technical solution are as follows: by setting an auxiliary support consisting of stiffening plates and continuous plates, the stiffening plates are fixed to the side of the steel beam, and the continuous plates are connected to the floor decking that overlaps on the side, providing a continuous and stable support surface for the floor decking on the side, effectively dispersing the load of the floor decking, avoiding the deformation or falling off problems caused by insufficient support in the prior art, and significantly enhancing the overall structural stability of the node connection.

[0007] Furthermore, the steel beam is an I-beam, with stiffening plates vertically fixed to the bottom plate and ribs of the I-beam. Multiple stiffening plates are provided on the same steel beam, and the continuous plate on the steel beam is connected to multiple stiffening plates.

[0008] Furthermore, the stiffening plate includes a fixed plate and a movable plate. The movable plate is mounted on the fixed plate in an adjustable manner, and the overall height of the stiffening plate can be changed by adjusting the position of the movable plate.

[0009] Furthermore, the fixed plate has slots on both sides along the vertical direction for engaging the movable plate. The movable plate has a sliding part that is slidably connected to the slots. The sliding part is provided with a locking element that is locked to the slots by friction. The locking element is elastic.

[0010] Furthermore, the clamping component includes a retaining ball movably disposed on the surface of the sliding part, and a spring supporting the retaining ball is also provided on the clamping component. When the retaining ball is subjected to external force, the spring is compressed and moves toward the interior of the clamping component.

[0011] Furthermore, the fixing plate is also provided with multiple vertically arranged locking holes at the corresponding slot positions, and the locking beads are driven by the spring to lock out of the locking holes.

[0012] Furthermore, a sealing plate is provided at the bottom of the corresponding slot of the fixing plate.

[0013] Furthermore, the movable plate is welded to the fixed plate after being adjusted to the correct position. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] like Figure 1-4As shown, this embodiment provides a bent node connection structure for floor decking, including: a steel beam 100 for connecting a first floor decking 200 and a second floor decking 300. The first floor decking 200 and the second floor decking 300 have a height difference, forming a fold line at the connection point. One floor decking slab overlaps the top of the steel beam 100, and the other floor decking slab overlaps the side of the steel beam 100. A transition rib 600 connects the first floor decking slab 200 and the second floor decking slab 300, providing a connection between them. Auxiliary support components include a stiffening slab 400 and a continuous plate 500. The stiffening slab 400 is fixed to the side of the steel beam 100, and the continuous plate 500 is fixed to the top of the stiffening slab 400. A space is left between the continuous plate 500 and the top of the steel beam 100. The floor decking slab overlapping the side of the steel beam 100 connects to the continuous plate 500. These auxiliary support components provide secondary reinforcement to the second floor decking slab 300, making it more stable and its connection with the first floor decking slab 200 more secure. The space between the top of the continuous plate 500 and the top of the steel beam 100 is at least greater than the thickness of the floor decking, so that the floor decking can be placed between the top of the continuous plate 500 and the top of the steel beam 100.

[0018] By setting an auxiliary support consisting of stiffening plate 400 and continuous plate 500, the stiffening plate 400 is fixed to the side of the steel beam 100, and the continuous plate 500 is connected to the floor decking that overlaps on the side, providing a continuous and stable support surface for the floor decking, effectively dispersing the load of the floor decking, avoiding the deformation or falling off problems caused by insufficient support in the prior art, and significantly enhancing the overall structural stability of the node connection.

[0019] In some embodiments, the steel beam 100 is an I-beam, and stiffening plates 400 are vertically fixed to the bottom plate 110 and ribs 120 of the I-beam. Multiple stiffening plates 400 are provided on the same steel beam 100, and a continuous plate 500 on the steel beam 100 connects to the multiple stiffening plates 400. Specifically, the bottom of the stiffening plate 400 connects to the top surface of the bottom plate 110 of the I-beam, and the inner side of the stiffening plate 400 connects to the ribs 120. The stiffening plates 400 can transfer the load to the I-beam, resulting in more connection points and a larger contact area between the I-beam and the floor decking. Specifically, the plane containing the stiffening plate 400 is perpendicular to the length direction of the steel beam 100. The stiffening plate 400 is generally trapezoidal in shape, meaning its width gradually increases from bottom to top.

[0020] In some embodiments, the stiffening rib 400 includes a fixed plate 410 and a movable plate 420. The movable plate 420 is height-adjustable and mounted on the fixed plate 410. The overall height of the stiffening rib 400 can be changed by adjusting the position of the movable plate 420. After the movable plate 420 is adjusted to the correct position, it is welded to the fixed plate 410. Since the height difference between the two floor decks at the steel beam 100 will change, the stiffening rib 400 must also change with the height difference to ensure sufficient support for the side floor decks. If the height of the stiffening rib 400 is not adjustable, various sizes must be made according to different height differences during construction, increasing the manufacturing difficulty and the amount of on-site sorting work. Adjustable stiffening ribs 400 can be manufactured in the same batch and adjusted to different heights as needed during use.

[0021] In some embodiments, the fixed plate 410 has slots 411 on both sides along the vertical direction for engaging the movable plate 420. The movable plate 420 has a sliding portion that is slidably connected to the slots 411. The sliding portion is provided with a locking member that is locked to the slots 411 by friction. The locking member is elastic. The slots 411 ensure that the movable plate 420 is tightly attached to the fixed plate 410 and can move along the vertical direction of the fixed plate 410. When the top of the movable plate 420 moves relative to the top of the fixed plate 410, the overall height of the rib plate 400 can be adjusted. The sliding portion can be both sides of the movable plate 420. The locking member provides sufficient friction when the movable plate 420 moves, so that the movable plate 420 can stop at its current position when the external force is removed.

[0022] In some embodiments, the locking member includes a locking ball 421 movably disposed on the surface of the sliding portion, and a spring supporting the locking ball 421 is also provided on the locking member. When the locking ball 421 is subjected to an external force, the spring is compressed and moves toward the interior of the locking member. The spring can press the locking ball 421 against the inner wall of the slot 411, so that the movement of the movable plate 420 has sufficient friction.

[0023] In some embodiments, the fixed plate 410 is further provided with a plurality of vertically arranged locking holes 412 at the position corresponding to the locking slot 411. The locking ball 421 is driven by the spring to engage the locking hole 412. When the locking ball 421 engages with one of the locking holes 412 of the fixed plate 410, it can play a fixing role, and at this time it no longer relies on the friction between the locking ball 421 and the inner wall of the locking slot 411. If the movable plate 420 still has not reached the optimal height, it can be pulled out or pushed in, so that the locking ball 421 is taken away from the current locking hole 412 and moved to the next locking hole 412. If the movable plate 420 moves to the optimal position, but the final position of the locking ball 421 is between two locking holes 412, the locking ball 421 is still pressed against the inner wall of the locking slot 411, and can still temporarily fix the movable plate 420. Finally, it is fixed by welding, and the weld 430 is located at the position where the top of the fixed plate 410 meets the movable plate 420.

[0024] In some embodiments, a sealing plate is provided at the bottom of the fixed plate 410 corresponding to the slot 411. The sealing plate can prevent the movable plate 420 from coming off the bottom of the fixed plate 410 before use.
