Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to the construction of floor decking, specifically a steel truss floor decking profiled steel sheet reinforcement and support system. Background Technology

[0002] With the rapid development of prefabricated steel-concrete composite structures in the construction industry, reinforced concrete truss floor decks have become widely used in public buildings, large industrial plants, high-rise buildings, and commercial facilities due to their excellent load-bearing capacity, convenient on-site construction, good fire resistance, and lightweight advantages. They can effectively and firmly connect with structural components such as steel beams and concrete columns, resisting the impact of natural disasters such as earthquakes, while significantly reducing labor input, shortening construction cycles, and lowering the overall load requirements of buildings, making them an important choice for load-bearing components in modern buildings.

[0003] During the construction of reinforced truss floor decking, profiled steel sheets serve as temporary load-bearing structures during the concrete pouring stage. If a stable and reliable support system is lacking, they are prone to deflection due to insufficient rigidity or uneven load distribution. This deformation directly leads to excessive deviations in the surface flatness of the subsequently poured concrete, and may even cause micro-cracks. This not only affects the building's appearance quality but may also weaken the structural strength of concrete components, leaving safety hazards. Existing support components are mostly customized designs, making it difficult to reuse them across projects, which does not meet the requirements of resource recycling in green construction. Summary of the Invention

[0004] The purpose of this invention is to address the problem that existing support components are mostly customized designs, making it difficult to achieve cross-project reuse and failing to meet the requirements of resource recycling in green construction. Therefore, a new structural design for a steel truss floor deck profiled steel sheet reinforcement support system is proposed.

[0005] This utility model is achieved through the following technical solution: A reinforced steel truss floor decking support system includes a reinforced steel truss floor decking. I-shaped base frames are respectively provided on both sides of the bottom end of the reinforced steel truss floor decking. An inclined support plate is detachably connected between the outer wall of the I-shaped base frame and the corresponding side edge of the bottom end of the reinforced steel truss floor decking. Two unit square tube support trusses are provided between two adjacent I-shaped base frames. Two sliding grooves are formed at the bottom ends of the two unit square tube support trusses on opposite sides. A connecting square rod is slidably connected within the sliding groove of one unit square tube support truss. The other end of the square rod is slidably connected to the groove of the unit square tube support truss on the other side, and a clamping and positioning mechanism is provided on the unit square tube support truss on the other side; two pairs of triangular pads are provided between the unit square tube support truss and the corresponding I-shaped base frame, each pair of triangular pads includes a top triangular pad block and a bottom triangular pad block stacked on top of each other, the top triangular pad block is fixed to the bottom end of the unit square tube support truss, and the bottom triangular pad block is movably connected to the I-shaped base frame; the I-shaped base frame is provided with a height adjustment mechanism and an anti-slip mechanism.

[0006] In a preferred embodiment of this utility model, bottom holes are provided on both sides of the bottom end of the unit square tube support truss on one side. The inner cavities of the two bottom holes are respectively connected to the inner cavities of two sliding grooves on the same side. A U-shaped connecting rod is provided at the bottom of the unit square tube support truss on one side. The two ends of the U-shaped connecting rod are fixedly connected to two connecting square rods through the two bottom holes respectively.

[0007] In a preferred embodiment of the present invention, the clamping and positioning mechanism includes a mounting bracket fixed to the bottom of the side wall of the unit square tube support truss on the other side. A driving part is mounted on the mounting bracket, and a clamping block is fixedly connected to the output end of the driving part. The clamping block slides through the surface of the unit square tube support truss and is placed in the inner cavity of its sliding groove.

[0008] In a preferred embodiment of this utility model, the driving unit may be an electric push rod or a cylinder.

[0009] In a preferred embodiment of this utility model, the drive unit and the mounting bracket are connected by a thread.

[0010] In a preferred embodiment of the present invention, the height adjustment mechanism includes a T-shaped groove formed on the inner wall of one side of the I-shaped base frame. A threaded rod is rotatably connected to the inner wall of the T-shaped groove, and a T-shaped slider is threadedly connected to the threaded rod. The T-shaped slider is slidably connected to the T-shaped groove.

[0011] In a preferred embodiment of this utility model, the top end of the T-shaped slider is fixedly connected to the bottom triangular pad on the same side, one end of the threaded rod rotates through the inner wall of the T-shaped groove and extends to the outside of the I-shaped base frame, and is fixedly connected with a knob.

[0012] In a preferred embodiment of the present invention, the anti-slip mechanism includes a buckle placed on one side of the threaded rod. The buckle has a square hole on its surface, and the position of the square hole corresponds to the position of the knob. The buckle is detachably connected to the I-shaped base frame by a bolt threaded to its bottom.

[0013] In a preferred embodiment of this utility model, the top triangular pad block and the bottom triangular pad block are stacked vertically and combined to form a rectangle, and lubricating oil is added between the contact surfaces of the top triangular pad block and the bottom triangular pad block.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model provides a steel truss floor decking reinforced with profiled steel sheet. The sliding connection design between the connecting square rods and the unit square tube supporting truss, combined with the detachable characteristics of the overall structure, such as the detachable connection between the inclined support plate and the I-shaped base frame, and the bolt connection between the buckle and the I-shaped base frame, allows each support component to be easily disassembled, recycled, and reassembled. This completely solves the problem that existing customized support components are difficult to reuse across projects, meeting the requirements of resource recycling in green construction. In addition, the docking function of the connecting square rods, the height adjustment mechanism, and the anti-slip mechanism work together to adapt to the support needs of different cantilever scenarios. Furthermore, the precise support of the triangular pads and the end reinforcement of the inclined support plate further improve the ease of operation and structural safety during construction, ensuring the reliable progress of the entire cantilever floor decking construction.

[0015] 2. This utility model provides a reinforced steel truss floor decking corrugated steel sheet reinforcement support system. The connecting square rod can accurately compensate for the gap between two unit square tube support trusses, effectively achieving stable connection between the two. This breaks the limitation of traditional support components that are difficult to adapt to different construction scenarios due to fixed spacing. The connecting square rod slides along the groove of the unit square tube support truss, and can flexibly adjust its position according to the actual spacing between the two support trusses during construction. The height adjustment mechanism uses a threaded rod and a T-shaped slider to drive the triangular pads (top and bottom triangular pad blocks) to adjust the support height. The lubricating oil on the contact surface of the block reduces adjustment resistance and ensures that the support height is accurately adapted to the construction requirements. Combined with the reinforcement of the cantilever end by the inclined support plate, it effectively suppresses the downward deflection of the profiled steel sheet and avoids surface flatness deviation and cracks in subsequent concrete pouring. The clamping and positioning mechanism pushes the clamping block and the connecting square rod through the drive unit to form a two-way fixation, ensuring that the force of adjacent I-shaped base frames is evenly transmitted. The anti-slip mechanism uses the mechanical locking and contact limit of the buckle to prevent the component from slipping. The design of the triangular pads (top and bottom triangular pad blocks) combined into a rectangle expands the force contact area and disperses the support stress. Attached Figure Description

Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 should fall within the protection scope of the present invention.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment provides a steel truss floor deck reinforced with profiled steel sheet, including a steel truss floor deck 1. An I-shaped base frame 2 is provided at the bottom end of the steel truss floor deck 1, which serves as the installation carrier for the unit square tube support truss 3, the height adjustment mechanism 8, and the anti-slip mechanism 9, so as to realize the orderly assembly of each support component. Two unit square tube support trusses 3 are provided between two adjacent I-shaped base frames 2, which bear the function of lateral load transfer. Two sliding grooves 4 are opened at the bottom ends of the two unit square tube support trusses 3 on opposite sides, providing sliding space for the connecting square rods 5, so that the connecting square rods 5 can be flexibly adjusted according to the actual spacing of the two unit square tube support trusses 3, and accurately compensate for the spacing difference. An inclined support plate 12 is detachably connected between the outer wall of the I-shaped base frame 2 and the corresponding side edge of the bottom end of the steel truss floor deck 1.

[0021] A connecting square rod 5 is slidably connected to the inner wall of the groove 4 of the unit square tube support truss 3 on one side. The other end of the connecting square rod 5 is slidably connected to the groove 4 of the unit square tube support truss 3 on the other side. The connecting square rod 5 slides along the groove 4, which can accurately compensate for the gap between the two unit square tube support trusses 3. A clamping and positioning mechanism 7 for fixing the connecting square rod 5 is provided on the unit square tube support truss 3 on the other side.

[0022] Both sides of the bottom end of the unit square tube support truss 3 are provided with bottom holes 10 to connect the inner cavity of the slide groove 4 with the external space, providing a passage for the two ends of the U-shaped connecting rod 11. The inner cavities of the two bottom holes 10 are respectively connected to the inner cavities of the two slide grooves 4 on the same side. The bottom of the unit square tube support truss 3 is provided with a U-shaped connecting rod 11, which can synchronously drive the two connecting square rods 5 to slide along the slide groove 4, avoiding positional deviation when adjusting a single connecting square rod 5. The two ends of the U-shaped connecting rod 11 are fixedly connected to the two connecting square rods 5 through the two bottom holes 10 respectively.

[0023] Two pairs of triangular shims 6 are provided between the unit square tube support truss 3 and the corresponding I-shaped base frame 2, with the two pairs of triangular shims 6 placed at both ends of the two. Each pair of triangular shims 6 includes a top triangular shim block 61 and a bottom triangular shim block 62 stacked vertically. The top triangular shim block 61 is fixed to the bottom end of the unit square tube support truss 3, and the bottom triangular shim block 62 is movably connected to the I-shaped base frame 2. The top triangular shim block 61 and the bottom triangular shim block 62 are stacked vertically and merged into a rectangular shape. The two are in inclined contact with each other, and the support height can be finely adjusted by relative sliding. Lubricating oil is added between the contact surfaces of the top triangular shim block 61 and the bottom triangular shim block 62. The lubricating oil on the contact surfaces reduces the adjustment resistance and ensures smooth height adjustment.

[0024] The clamping and positioning mechanism 7 includes a mounting bracket 71 fixed to the bottom of the side wall of the unit square tube support truss 3 on the other side. A drive unit 72 is mounted on the mounting bracket 71, which serves as a power source to drive the clamping block 73 to move horizontally, thereby clamping the connecting square rod 5 and ensuring the stability of the connection between the two unit square tube support trusses 3. The output end of the drive unit 72 is fixedly connected to the clamping block 73, which can be made of rubber. The clamping block 73 slides through the surface of the unit square tube support truss 3 on the same side and is placed in the inner cavity of its sliding groove 4. The drive unit 72 can be an electric push rod or a cylinder, which automatically drives the clamping block 73 to move. Alternatively, the drive unit 72 can be threadedly connected to the mounting bracket 71, for example, by using a fastening bolt, and the clamping block 73 can be moved by manually rotating the drive unit 72.

[0025] The I-shaped base frame 2 is equipped with a height adjustment mechanism 8, which includes a pair of T-shaped grooves 81 on the inner wall of one side of the I-shaped base frame 2. These grooves provide sliding guidance for the T-shaped slider 83 and limit the movement trajectory of the T-shaped slider 83. A threaded rod 82 is rotatably connected to the inner wall of the T-shaped groove 81. The T-shaped slider 83 is threadedly connected to the threaded rod 82. The T-shaped slider 83 is slidably connected to the T-shaped groove 81. The top of the T-shaped slider 83 is fixedly connected to the bottom triangular pad 62 on the same side. One end of the threaded rod 82 rotates through the inner wall of the T-shaped groove 81 and extends to the outside of the I-shaped base frame 2, and is fixedly connected to a knob 84.

[0026] The I-shaped base frame 2 is equipped with an anti-slip mechanism 9, which includes a buckle 91 located on one side of the threaded rod 82. The buckle 91 has a square hole 92 on its surface to avoid contact or conflict with the knob 84 during installation. The position of the square hole 92 corresponds to the position of the knob 84. The buckle 91 is detachably fixed to the I-shaped base frame 2 by a bolt connected to its bottom thread. One side of the buckle 91 abuts against the top triangular pad 61.

[0027] The usage process of the steel truss floor decking profiled steel sheet reinforcement and support system provided in this embodiment is as follows: First, using the I-shaped base frame 2 as the core installation carrier, two unit square tube support trusses 3 are erected between adjacent I-shaped base frames 2. By manually moving the U-shaped connecting rod 11, the two connecting square rods 5 slide along the slide groove 4 of one unit square tube support truss 3 until they enter the slide groove 4 of the other unit square tube support truss 3. This completes the splicing of the two unit square tube support trusses 3. The support height is adjusted by the height adjustment mechanism 8. Rotating the knob 84 on the outside of the I-shaped base frame 2 drives the threaded rod 82 to rotate in the T-shaped slide groove 81, causing the T-shaped slider 83, which is threadedly connected to the threaded rod 82, to move along the T-shaped slide groove 81, thereby pushing the bottom triangular pad block 62 to one side. During the movement, because the top triangular pad block 61 is fixedly connected to the unit square tube support truss 3, the top triangular pad block 61 and the bottom triangular pad block 62 remain in contact with the support truss 3. The corner pad 62 slides through the inclined surface to achieve precise adaptation of the support height of the unit square tube support truss 3. Then, the clamping and positioning mechanism 7 is activated. The drive part 72, which is fixed on the mounting frame 71 of the unit square tube support truss 3 on the other side, pushes the clamping block 73 into the slide groove 4 and abuts against the connecting square rod 5. Then, the anti-slip mechanism 9 is used for safety locking. The buckle 91 is fixed to the I-shaped base frame 2 with bolts. One side of the buckle 91 abuts against the top triangular pad 61 to prevent it from falling off. Finally, the inclined support plate 12 is detachably connected between the outer wall of the I-shaped base frame 2 and the bottom edge of the steel truss floor deck 1 to reinforce the cantilever end structure and suppress the downward deflection of the profiled steel plate. Finally, a flexible, stable, and secure cantilever floor deck support system is formed to ensure the reliable progress of concrete pouring construction.
