Description

Technical Field

[0001] This utility model belongs to the technical field of building installation auxiliary equipment, specifically relating to a floor decking attachment arching device. Background Technology

[0002] Floor decking is a core material in modern construction. Its lightweight, convenient construction, and high load-bearing capacity align perfectly with the global trends of green building and industrialized construction, leading to its widespread use in various construction projects. Floor decking construction requires the installation of the steel frame structure and floor decking first, followed by rebar tying and concrete pouring on the floor decking surface. During this process, the floor decking undergoes significant deflection under its own weight and construction loads, easily causing noticeable gaps at the joints between adjacent steel plates. In severe cases, this can lead to structural deformation and cracking, directly impacting the overall structural stability of the building.

[0003] To address the aforementioned deflection and deformation issues, traditional construction methods typically involve erecting temporary support frames on the steel beams on both sides of the floor deck's base using steel pipes or other supporting materials. This traditional support method places high demands on the foundation conditions, the verticality of the support frame, and its overall stability. Furthermore, it requires a significant investment of supporting materials and a substantial workforce to install and level the support frames, ensuring the floor deck's stability and load-bearing capacity. The overall construction process is material-intensive, labor-intensive, and cumbersome.

[0004] Therefore, there is a need for a floor decking attachment arching device that is highly safe, easy to install, and quick to assemble. Utility Model Content

[0005] The purpose of this invention is to provide a floor decking attachment arching device that is highly safe, easy to install, and quick to assemble, thereby effectively improving construction efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A floor decking attachment arching device includes a vertical steel pipe fixedly fitted with a first sleeve and horizontal steel pipes symmetrically arranged on the left and right sides of the first sleeve. The opposite ends of the two horizontal steel pipes are fixedly connected to the first sleeve, and the other ends of the two pipes are respectively provided with matching overlapping components that are detachably installed on steel beams on both sides of the bottom of the floor decking. The upper end of the vertical steel pipe is provided with a tightening component that can be moved up and down to abut against the bottom of the floor decking.

[0007] A further improvement of the present invention is that: a second sleeve is fixedly fitted at the lower end of the vertical steel pipe, and diagonal braces are symmetrically arranged on the left and right sides of the second sleeve. One end of the diagonal brace is fixedly connected to the second sleeve, and the other end is fixedly connected to the end of the horizontal steel pipe on the same side with an overlapping component.

[0008] A further improvement of the present invention is that the overlapping component includes a buckle that is fixedly connected to one end of the transverse steel pipe and adapted to the steel beam on one side of the bottom of the floor deck, and a bolt that is set on the buckle and can be installed on the steel beam on one side of the bottom of the floor deck.

[0009] A further improvement of the present invention is that the buckle includes a vertical plate fixedly connected to one end of the transverse steel pipe and a horizontal plate of a steel beam adapted to the bottom side of the floor deck, which is respectively set at the upper and lower ends of the vertical plate. The bolt passes vertically through the horizontal plate at the lower end of the vertical plate and is threadedly connected to it.

[0010] A further improvement of this utility model is that the length of the horizontal plate at the upper end of the vertical plate is greater than the length of the horizontal plate at the lower end.

[0011] A further improvement of the present invention is that the tightening component includes a vertically arranged screw and an adjusting nut threaded onto the screw. The upper end of the screw is provided with a top support that can abut against the bottom of the floor deck, and its lower end passes through the adjusting nut and is inserted into the upper end of the vertical steel pipe.

[0012] A further improvement of this utility model is that the diameter of the upper end of the vertical steel pipe is between the inner and outer diameters of the adjusting nut, and the adjusting nut can be placed and abutted against the upper end of the vertical steel pipe.

[0013] A further improvement of the present invention is that the top support includes a U-shaped plate fixedly connected to the upper end of the screw and a support rod that can be placed in the groove of the U-shaped plate and abuts against the bottom of the floor deck.

[0014] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows: The floor decking attachment arching device provided by this utility model can conveniently and quickly support the floor decking and evenly distribute its load, effectively ensuring the arching value, saving labor and material costs while improving construction efficiency and quality, and can also effectively improve the safety and accuracy of floor decking construction.

[0015] This utility model constructs a cross-shaped support structure using a vertical steel pipe, a first sleeve, and two symmetrically arranged horizontal steel pipes. Combined with detachable overlapping components and adjustable tightening components, the attached design eliminates the need for an additional independent support system. It is directly fixed to the steel beam at the bottom of the floor slab, significantly saving construction space and support material input, and is suitable for narrow working environments. The detachable nature of the overlapping components facilitates rapid installation, disassembly, and reuse of the device, reducing construction costs and minimizing interference with subsequent processes. The adjustable tightening components can accommodate different arching height requirements, flexibly adjusting the stress state at the bottom of the floor slab and effectively preventing downward deflection caused by the floor slab's own weight or shrinkage after pouring.

[0016] This utility model forms a triangular support system by adding a second sleeve and symmetrical diagonal braces at the lower end of the vertical steel pipe. This system has strong resistance to lateral displacement and overturning, reduces the risk of component deformation, and extends the service life of the device. Furthermore, the second sleeve provides a stable connection point for the diagonal braces, ensuring the integrity of the connection between the diagonal braces and the vertical and horizontal steel pipes, strengthening the overall rigidity of the device, and enabling the device to maintain structural stability under long-term load conditions.

[0017] The lap joint provided by this utility model adopts a combination structure of buckles and bolts, which takes into account both connection reliability and ease of operation. On the one hand, the buckles can be adapted to the steel beam structure at the bottom of the floor deck, realizing quick positioning and docking, and greatly improving installation efficiency. On the other hand, the bolts can realize the fastening connection between the buckles and the steel beams, preventing the device from loosening or shifting under stress, ensuring stable arching effect. At the same time, the detachability of the bolt connection makes it easy to quickly disassemble the device after construction, and the low component wear allows it to be reused in subsequent projects, reducing construction material costs.

[0018] The buckle provided by this utility model optimizes the compatibility and stress performance with steel beams through the cooperation of vertical plates and upper and lower horizontal plates. The upper and lower horizontal plates can respectively fit the upper and lower surfaces of the steel beam to form a wrap-around fit effect, which greatly increases the contact area between the buckle and the steel beam. The bolts penetrate vertically through the lower horizontal plate and are threaded, so that the locking force is applied vertically to the surface of the steel beam, making the locking effect more stable. Moreover, the threaded connection is reversible, which facilitates disassembly and adjustment later.

[0019] The buckle provided by this utility model has an upper horizontal plate that is longer than the lower horizontal plate. The longer upper horizontal plate can increase the contact range with the upper surface of the steel beam, improve the buckle's wrapping effect on the steel beam, effectively prevent the buckle from slipping off, and enhance the reliability of the connection.

[0020] The clamping component provided by this utility model achieves precise control and flexible support of the arching height through the cooperation of a screw, adjusting nut, and top support. The threaded engagement of the screw and adjusting nut allows for micro-adjustment with high precision. The top support increases the contact area with the bottom of the floor deck, preventing the screw end from directly pressing against the floor deck and causing localized pressure damage, thus protecting the forming quality of the floor deck. The concealed design of the lower end of the screw being inserted into the vertical steel pipe not only makes the structure more compact and reduces construction interference, but also provides lateral restraint for the screw through the vertical steel pipe.

[0021] This utility model uses a vertical steel pipe with the upper end of the pipe having a diameter between the inner and outer diameters of the adjusting nut, forming a limiting support structure. This allows the adjusting nut to be stably placed and abutted against the upper end of the vertical steel pipe. The upper end of the vertical steel pipe provides rigid support to the adjusting nut, ensuring the stability of the arching height during adjustment. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to embodiments: like Figures 1-3As shown, this utility model provides a floor decking attachment arching device, including a vertical steel pipe 2 and two horizontal steel pipes 3. A first sleeve 1 is fixedly sleeved on the vertical steel pipe 2, and the first sleeve 1 is located in the upper middle part of the vertical steel pipe 2. The two horizontal steel pipes 3 are symmetrically arranged on the left and right sides of the first sleeve 1, thus forming a cross support structure with the vertical steel pipe 2. The opposite ends of the two horizontal steel pipes 3 are respectively fixedly connected to the first sleeve 1, and the other ends of the two horizontal steel pipes 3 are respectively provided with overlapping parts 4. The two overlapping parts 4 can be detachably installed on the steel beams on both sides of the bottom of the floor decking, which facilitates the quick installation, disassembly and reuse of the device, reduces construction costs, and reduces interference with subsequent processes. The upper end of the vertical steel pipe 2 is provided with a vertically adjustable tightening part 5, which is used to abut against the bottom of the floor decking, which can adapt to different arching height requirements, flexibly adjust the stress state of the bottom of the floor decking, and effectively avoid the downward deformation caused by the self-weight or shrinkage of the floor decking after pouring.

[0024] Furthermore, a second sleeve 6 is fixedly fitted at the lower end of the vertical steel pipe 2. Diagonal braces 7 are symmetrically arranged on the left and right sides of the second sleeve 6. Specifically, one end of the diagonal brace 7 is fixedly connected to the second sleeve 6, and the other end is fixedly connected to the end of the overlapping component 4 of the horizontal steel pipe 3 on the same side, thereby forming a triangular support force system with strong resistance to lateral displacement and overturning, reducing the risk of component deformation, extending the service life of the device, and the second sleeve 6 provides a stable connection base for the diagonal brace 7, ensuring the integrity of the connection between the diagonal brace 7 and the vertical steel pipe 2 and the horizontal steel pipe 3, strengthening the overall rigidity of the device, and enabling the device to maintain structural stability under long-term load conditions.

[0025] like Figure 1 and Figure 3 As shown, the overlapping component 4 includes a clip 4-1 and a bolt 4-2. The clip 4-1 is fixedly connected to one end of the transverse steel pipe 3, and the clip 4-1 is adapted to the steel beam on one side of the bottom of the floor deck, thereby achieving rapid positioning and docking, greatly improving installation efficiency. The bolt 4-2 is set on the clip 4-1 to install the clip 4-1 on the steel beam on one side of the bottom of the floor deck, preventing the device from loosening or shifting under stress, ensuring stable arching effect. At the same time, the detachability of the bolt 4-2 makes it easy to quickly disassemble the device after construction, and the component wear is low, so it can be reused in subsequent projects, reducing construction material costs.

[0026] Furthermore, the clip 4-1 includes a vertical plate and two horizontal plates. The vertical plate is fixedly connected to one end of the horizontal steel pipe 3. The two horizontal plates are respectively set at the upper and lower ends of the vertical plate and are adapted to the steel beam on one side of the bottom of the floor deck. That is, the two horizontal plates can respectively fit against the upper and lower surfaces of the steel beam to form a wrap-around fit effect, thereby increasing the contact area between the clip 4-1 and the steel beam. The bolt 4-2 vertically penetrates the horizontal plate at the lower end of the vertical plate and is threadedly connected to it, so that the locking force acts vertically on the surface of the steel beam, making the locking effect more stable. Moreover, the threaded connection is reversible, which facilitates disassembly and adjustment later. Specifically, the length of the horizontal plate at the upper end of the vertical plate is greater than the length of the horizontal plate at the lower end. The longer upper horizontal plate can increase the contact range with the upper surface of the steel beam, further improving the wrapping degree of the clip 4-1 on the steel beam and effectively preventing the clip 4-1 from slipping off.

[0027] like Figure 1 and Figure 2 As shown, the tightening component 5 includes a vertically arranged screw 5-1 and an adjusting nut 5-2 threaded onto the screw 5-1. The upper end of the screw 5-1 is provided with a top support 5-3 that can abut against the bottom of the floor decking. Its lower end passes through the adjusting nut 5-2 and is inserted into the upper end of the vertical steel pipe 2. This achieves precise control of the arching height and flexible support. The threaded engagement between the screw 5-1 and the adjusting nut 5-2 allows for micro-adjustment with high precision. The top support 5-3 increases the contact area with the bottom of the floor decking, preventing the end of the screw 5-1 from directly pressing against the floor decking and causing local pressure damage, thus protecting the forming quality of the floor decking. The concealed design of the lower end of the screw 5-1 being inserted into the vertical steel pipe 2 not only makes the structure more compact and reduces construction interference, but also provides lateral restraint for the screw 5-1 through the vertical steel pipe 2.

[0028] Furthermore, the diameter of the upper end of the vertical steel pipe 2 is between the inner and outer diameters of the adjusting nut 5-2, thus forming a limiting support structure. This allows the adjusting nut 5-2 to be stably placed and abutted against the upper end of the vertical steel pipe 2. The upper end of the vertical steel pipe 2 provides rigid support for the adjusting nut 5-2, ensuring the stability of the arch height during adjustment. Specifically, the top support 5-3 includes a U-shaped plate and a support rod. The U-shaped plate is fixedly connected to the upper end of the screw 5-1. The support rod is arranged along the length of the floor decking. The support rod can be placed in the groove of the U-shaped plate and abut against the bottom of the floor decking. That is, the support rod is located between the groove of the U-shaped plate and the bottom of the floor decking, thus providing good support.

[0029] During construction, the device is first fixed to the steel beams on both sides of the bottom of the floor slab using two overlapping components 4. The clips 4-1 are positioned by their upper and lower horizontal plates encircling the steel beams and locked in place by bolts 4-2 to prevent displacement. Then, the arch height is adjusted using the tightening component 5. The adjusting nut 5-2 is supported by the upper end of the vertical steel pipe 2, and rotating the adjusting nut 5-2 causes the screw 5-1 to rise and fall slightly, allowing the top support 5-3 to abut against the bottom of the floor slab. After construction, the device can be disassembled by removing bolts 4-2, enabling reuse and reducing costs without interfering with subsequent processes.
