Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a steel structure floor deck connection structure. Background Technology
[0002] In the field of steel structure buildings, steel truss floor decking is widely used due to its advantages such as convenient construction and high comprehensive benefits. In actual construction, multiple floor deckings need to be spliced and installed on top of steel beams.
[0003] Currently, traditional methods typically rely on on-site welding or the use of specific connectors for fixing. On-site welding involves directly welding the end support steel bars or additional connecting steel plates to the lower beams after the adjacent floor slabs are in place. Using specific connectors involves using pre-designed studs, self-locking screws, and special clamps to connect the floor decking to the special clamps.
[0004] The existing technical solutions have the following drawbacks: when the spacing between the ends of adjacent floor deckings exceeds the normal range due to manufacturing and installation errors, traditional specific connectors are difficult to flexibly adapt to the spacing between different decking ends. Utility Model Content
[0005] The purpose of this utility model is to provide a steel structure floor deck connection structure to solve the problems existing in the prior art.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A steel structure floor deck connection structure includes a first steel truss floor deck, a second steel truss floor deck, and a steel beam. The first and second steel truss floor decks are symmetrically arranged on the top of the steel beam, and are spaced apart. A common adjustable connection component is provided at one end of each steel truss floor deck that is close to the other. The adjustable connection component is used to connect the first and second steel truss floor decks together.
[0007] By adopting the above technical solution, the width of the adjustable connecting component is adjusted according to the distance between the first truss floor deck and the second truss floor deck, so that the adjustable connecting component can connect the close ends of the first steel truss floor deck and the second steel truss floor deck together. Then, concrete is injected into the adjustable connecting component to enhance the connection strength between the first steel truss floor deck and the second steel truss floor deck, thereby flexibly adapting to different end spacings between the first truss floor deck and the second truss floor deck, and improving construction efficiency.
[0008] In a further embodiment, the adjustable connecting assembly includes a fixed plate, a movable plate, a first screw, a second screw, and a welding plate. The fixed plate includes a vertical plate, a horizontal plate, and a mounting plate. The vertical plate is sleeved on the right end of the first steel truss floor slab. The horizontal plate is fixedly installed at the bottom of the vertical plate. The mounting plate is fixedly installed at the front of the vertical plate and the horizontal plate. The first screw passes through the top rear end of the vertical plate, and the second screw passes through the bottom front end of the vertical plate. Both the first screw and the second screw are rotatably connected to the vertical plate. The first screw and the second screw are arranged in parallel. The movable plate is movably installed on the first screw and the second screw. The welding plate is located on the side of the vertical plate and the movable plate away from the mounting plate.
[0009] By adopting the above technical solution, the first screw and the second screw are rotated simultaneously to make the moving plate move left and right along the axis of the first screw and the second screw, thereby moving the moving plate closer to or away from the vertical plate. When the moving plate is engaged with the second truss floor deck, the first screw and the second screw are stopped from rotating. Then, a welding plate of suitable width is selected and welded to the back of the mounting plate, so that the vertical plate, the moving plate, the horizontal plate, the mounting plate and the welding plate can form a rectangular cavity. Finally, concrete is injected into the rectangular cavity.
[0010] In a further embodiment, the first steel truss floor slab includes a base plate and a steel truss. The steel truss is fixedly installed on the top of the base plate. The steel truss includes an upper chord steel bar, a lower chord steel bar, and web steel bars. There are two lower chord steel bars, which are spaced apart at the bottom of the web steel bars. The upper chord steel bars are located at the top of the web steel bars. Both the vertical plate and the movable plate are provided with a first through hole, a second through hole, a third through hole, and a clearance opening that are through the left and right sides.
[0011] By adopting the above technical solution, the first through hole is used to avoid the upper chord reinforcement, the second through hole and the third through hole are both used to avoid the lower chord reinforcement, and the avoidance opening is used to avoid the bottom plate, so that the vertical plate and the movable plate can pass through the first truss floor deck and the second truss floor deck respectively.
[0012] In a further embodiment, the top of the horizontal plate is lower than the bottom of the first steel truss floor, the bottom of the first screw is higher than the top of the first steel truss floor slab, the bottom of the second screw is higher than the top of the horizontal plate, and the top of the second screw is lower than the bottom of the first steel truss floor slab.
[0013] By adopting the above technical solution, it is easy to place the adjustable connection component between the first truss floor deck and the second truss floor deck.
[0014] In a further embodiment, a handle is fixedly installed at the left end of both the first screw and the second screw.
[0015] By adopting the above technical solution, it is convenient for operators to rotate the first screw and the second screw.
[0016] In a further embodiment, shims are provided at both the left and right ends of the top of the steel beam.
[0017] By adopting the above technical solution, the shims create gaps between the steel beams and the first truss floor deck and the second truss floor deck, respectively, providing the necessary space for the horizontal plate to enter between the first truss floor deck and the second truss floor deck.
[0018] In summary, this utility model has the following beneficial effects: 1. By using steel beams, adjustable connecting components, and shims, the width of the adjustable connecting components can be adjusted according to the distance between the first and second truss floor decks. This allows the adjustable connecting components to connect the ends of the first and second steel truss floor decks that are close to each other. Concrete is then injected into the adjustable connecting components to enhance the connection strength between the first and second steel truss floor decks. This allows for flexible adaptation to different end spacings between the first and second truss floor decks, thereby improving construction efficiency. Attached Figure Description

[0023] Example 1: like Figures 1-3 As shown, a steel structure floor deck connection structure includes a first steel truss floor deck 1, a second steel truss floor deck 2, and a steel beam 3. The first steel truss floor deck 1 and the second steel truss floor deck 2 are symmetrically arranged on the top of the steel beam 3, and the first steel truss floor deck 1 and the second steel truss floor deck 2 are spaced apart. The same adjustable connection component 4 is provided at the ends of the first steel truss floor deck 1 and the second steel truss floor deck 2 that are close to each other. The adjustable connection component 4 is used to connect the first steel truss floor deck 1 and the second steel truss floor deck 2 together. The adjustable connection assembly 4 includes a fixed plate 41, a movable plate 42, a first screw 43, a second screw 44, and a welding plate 45. The fixed plate 41 includes a vertical plate 411, a horizontal plate 412, and a mounting plate 413. The vertical plate 411 is sleeved on the right end of the first steel truss floor deck 1. The horizontal plate 412 is fixedly installed at the bottom of the vertical plate 411. The mounting plate 413 is fixedly installed at the front of the vertical plate 411 and the horizontal plate 412. The first screw 43 passes through the top rear end of the vertical plate 411, and the second screw 44 passes through the bottom front end of the vertical plate 411. The first screw 43 and the second screw 44 are rotatably connected to the vertical plate 411. The first screw 43 and the second screw 44 are arranged in parallel. The movable plate 42 is movably installed on the first screw 43 and the second screw 44. The welding plate 45 is arranged on the side of the vertical plate 411 and the movable plate 42 away from the mounting plate 413. The first steel truss floor slab 1 includes a base plate and a steel truss. The steel truss is fixedly installed on the top of the base plate. The steel truss includes top chord steel bars, bottom chord steel bars, and web steel bars. There are two bottom chord steel bars, which are spaced apart at the bottom of the web steel bars. The top chord steel bars are located at the top of the web steel bars. The vertical plate 411 and the movable plate 42 are both provided with a first through hole, a second through hole, a third through hole, and a clearance hole that are through the left and right sides. The top of the horizontal plate 412 is lower than the bottom of the first steel truss floor slab 1. The bottom of the first screw rod 43 is higher than the top of the first steel truss floor slab 1. The bottom of the second screw rod 44 is higher than the top of the horizontal plate 412. The top of the second screw rod 44 is lower than the bottom of the first steel truss floor slab 1. Handles are fixedly installed on the left ends of the first screw rod 43 and the second screw rod 44. Shims 5 are provided on both the left and right ends of the top of the steel beam 3.
[0024] Specific implementation process: First, place the first and second steel truss floor decks symmetrically on top of the steel beam, left and right respectively. Use the shims at both ends of the steel beam top to create a gap between the steel beam and the floor decks. Next, install the adjustable connection assembly. Place the vertical plate of the fixed plate onto the right end of the first steel truss floor deck. At this time, the horizontal plate is located below the first steel truss floor deck, and the moving plate also moves between the first and second steel truss floor decks along with the fixed plate. Then, rotate the handles on the left ends of the first and second screws simultaneously. Since the first and second screws are rotatably connected to the vertical plate, the moving plate will move along the axis of the first and second screws. The moving plate moves to the right, gradually approaching the second steel truss floor deck until it is engaged with the second steel truss floor deck, at which point the rotation stops. Then, based on the distance between the vertical plate and the moving plate, a welding plate of appropriate width is selected and welded to the back of the mounting plate, forming a rectangular cavity with the vertical plate, moving plate, horizontal plate, mounting plate, and welding plate. Finally, concrete is poured into the rectangular cavity. After the concrete solidifies, the connection strength between the first and second steel truss floor decks is enhanced, completing the entire connection process. This allows for flexible adaptation to different end distances between the first and second steel truss floor decks, thereby improving construction efficiency.
