Description

Technical Field

[0001] This utility model relates to the field of floor decking technology, and in particular to a floor decking that does not require disassembly. Background Technology

[0002] A truss made of steel bars as the top chord, bottom chord, and web members, connected by resistance spot welding, is called a steel truss. A composite load-bearing slab formed by connecting the steel truss and the base plate by resistance spot welding is called a steel truss floor deck. This enables mechanized production, which is conducive to uniform spacing of steel bars and consistent thickness of concrete cover, thus improving the construction quality of the floor slab.

[0003] Chinese utility model patent CN220908898U discloses a snap-fit ​​type steel truss floor deck, relating to the field of steel trusses. It includes a base plate with multiple slots on both sides of its upper surface. A locking element is installed inside two corresponding slots. A positioning block is located inside the locking element on the upper surface of the base plate. Multiple cavities are formed on the upper surface of the base plate, each containing a locking device, including a bidirectional threaded sleeve. This utility model, through the cooperation of the locking element and the pin, allows the locking element to secure the web reinforcement bars to the base plate. Rotating a knob, through the cooperation of the external rotating rod and the limiting strip, drives the worm gear to rotate. After the external threaded sleeve locks with the threaded groove, the internal bidirectional threaded sleeve remains stable, thus keeping the pin stably locked in the locking element, thereby increasing the overall stability of the device and facilitating installation and disassembly.

[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: To reduce the difficulty of positioning, the device fixes the steel truss by pre-connecting the lower chord steel bars to the clamps and fixing the clamps to the base plate. During operation, the operator pre-fixes the clamps by attracting the first and second magnetic blocks together, and then fixes the clamps by rotating a knob to move two pins on the same side. In actual use, due to the poor stability between the first and second magnetic blocks, external forces can easily cause them to separate. When a passerby accidentally touches the steel truss, one of the clamps may move upwards, resulting in a poor user experience. Utility Model Content

[0005] To solve the above problems, this utility model provides a floor decking that does not require dismantling.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a non-removable floor deck, including a base plate, a clamp set on the base plate, a lower chord steel bar connected to the clamp, a web steel bar connected to the lower chord steel bar, and an upper chord steel bar connected to the web steel bar. A fixing block is installed on the inner wall of the clamp, a positioning block is fixed on the bottom surface of the clamp, a limiting groove is opened on the side wall of the positioning block, a positioning groove matching the positioning block is opened on the upper surface of the base plate, and a limiting component for limiting the positioning block is provided on the positioning block.

[0007] By adopting the above technical solution, when workers need to install the floor decking, they need to connect the lower chord reinforcement with the clamps and fixing blocks. This allows the lower chord reinforcement to be initially stabilized under the combined action of the clamps and fixing blocks. Subsequently, workers need to connect the positioning block with the positioning groove, which allows the limiting component to automatically limit the positioning block, thereby stabilizing the positioning block and reducing the difficulty for subsequent workers to fix the positioning block.

[0008] Furthermore, the limiting assembly includes a limiting rod slidably disposed in the limiting groove and a compression spring fixed at one end to the side wall of the limiting rod, the other end of the compression spring being fixed to the inner wall of the limiting groove.

[0009] Furthermore, a first inclined surface is provided on the edge where the bottom surface of the limiting rod intersects with the side wall away from the compression spring.

[0010] Furthermore, the inner wall of the positioning groove is provided with a limiting hole that matches the limiting rod.

[0011] By adopting the above technical solution, when the operator connects the positioning block and the positioning groove, the limiting rod moves completely into the limiting groove under the action of the first inclined surface. Subsequently, the operator only needs to continue sliding the positioning block downwards to align the limiting groove with the limiting hole, thereby connecting the limiting rod with the limiting hole under the action of the compression spring, thus blocking the positioning block and keeping the limiting rod stable.

[0012] Furthermore, a first threaded groove is formed through the inner wall of the limiting groove, and a second threaded groove is formed on the side wall of the base plate, which communicates with the first threaded groove. A threaded rod is threadedly connected to the first threaded groove and the second threaded groove. A placement groove is formed on the side wall of the limiting rod near the first threaded groove. A second inclined surface is formed on the edge where the side wall of the placement groove away from the compression spring intersects with the side wall of the limiting rod near the first threaded groove.

[0013] By adopting the above technical solution, when the limiting rod and the limiting hole are connected, in actual use, the limiting rod may not be able to move to the farthest end due to tolerance. At this time, the operator only needs to rotate the threaded rod to move the threaded rod closer to the limiting rod, thereby making the threaded rod press against the second inclined surface. This allows the limiting rod to continue moving closer to the limiting hole under the action of the threaded rod, thus pressing the limiting rod against the inner wall of the limiting hole. This reduces the difficulty of installing the limiting rod and reduces the probability of the limiting rod resetting under the action of external force.

[0014] Furthermore, a first connecting groove is provided through the inner wall of the limiting groove, a second connecting groove is provided on the side wall of the bottom plate and communicates with the first connecting groove, and a third inclined surface is provided on the edge where the side wall of the placement groove near the compression spring intersects with the side wall of the limiting rod near the first threaded groove.

[0015] By adopting the above technical solution, when workers need to remove the positioning block due to installation misalignment, they need to separate the limiting rod from the limiting hole. At this time, workers need to rotate the threaded rod in the opposite direction to separate the threaded rod from the second threaded groove. Furthermore, workers need to connect the threaded rod to the second connecting groove and push the threaded rod to make it press against the third inclined surface, thereby separating the limiting rod from the limiting hole under the action of the threaded rod.

[0016] Furthermore, a handle is fixed to the end of the threaded rod to reduce the difficulty for workers to turn the threaded rod.

[0017] Furthermore, a sealing gasket for sealing the second connecting groove is provided on the second connecting groove.

[0018] By adopting the above technical solution, when the staff does not need to use the second connecting groove, the staff only needs to connect the sealing gasket to the second connecting groove to seal the second connecting groove.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. In this application, when workers need to install the floor decking, they need to connect the lower chord reinforcement with the clamps and fixing blocks to initially stabilize the lower chord reinforcement under the combined action of the clamps and fixing blocks. Subsequently, workers need to connect the positioning block with the positioning groove to automatically limit the positioning block with the limiting component, thereby stabilizing the positioning block and reducing the difficulty for subsequent workers to fix the positioning block.

[0021] 2. In this application, when the operator connects the positioning block and the positioning groove, the limiting rod moves completely into the limiting groove under the action of the first inclined surface. Subsequently, the operator only needs to continue sliding the positioning block downward to make the limiting groove and the limiting hole align, so that the limiting rod connects with the limiting hole under the action of the compression spring, thereby blocking the positioning block and keeping the limiting rod stable;

[0022] 3. In this application, when the limiting rod and the limiting hole are connected, in actual use, the limiting rod may not be able to move to the farthest end due to tolerance. At this time, the operator only needs to rotate the threaded rod to move the threaded rod closer to the limiting rod, thereby making the threaded rod press against the second inclined surface. This allows the limiting rod to continue moving closer to the limiting hole under the action of the threaded rod, thus pressing the limiting rod against the inner wall of the limiting hole. This reduces the difficulty for the operator to install the limiting rod and reduces the probability of the limiting rod resetting under the action of external force. Attached Figure Description

Detailed Implementation

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1-5 As shown in the embodiment, this application discloses a non-removable floor decking, including a base plate 1, a clamping component 11, a fixing block 12, a lower chord reinforcing bar 2, a web reinforcing bar 21, an upper chord reinforcing bar 3, a positioning block 31, a limiting component 5, a threaded rod 71, a handle 85, and a sealing gasket 9. The clamping component 11 is disposed on the base plate 1, and the lower chord reinforcing bar 2 is connected to the clamping component 11. The web reinforcing bar 21 is connected to the lower chord reinforcing bar 2. The upper chord reinforcing bar 3 is connected to the web reinforcing bar 21. The fixing block 12 is a block structure and is installed on the inner wall of the clamping component 11. The positioning block 31 is a rectangular block structure and is fixed to the bottom surface of the clamping component 11.

[0031] A limiting groove 4 is formed on the side wall of the positioning block 31, and a positioning groove 41 matching the positioning block 31 is formed on the upper surface of the base plate 1. A limiting component 5 is set on the positioning block 31 to limit the positioning block 31. The limiting component 5 includes a limiting rod 51 and a compression spring 52. The limiting rod 51 is a rectangular rod structure. The limiting rod 51 is slidably set in the limiting groove 4. A first inclined surface 53 is formed on the edge where the bottom surface of the limiting rod 51 intersects with the side wall away from the compression spring 52, and a limiting hole 6 matching the limiting rod 51 is formed on the inner wall of the positioning groove 41. One end of the compression spring 52 is fixed to the side wall of the limiting rod 51, and the other end of the compression spring 52 is fixed to the inner wall of the limiting groove 4.

[0032] When the operator connects the positioning block 31 to the positioning groove 41, the limiting rod 51 moves completely into the limiting groove 4 under the action of the first inclined surface 53. Subsequently, the operator only needs to continue sliding the positioning block 31 downward to make the limiting groove 4 align with the limiting hole 6, so that the limiting rod 51 connects with the limiting hole 6 under the action of the compression spring 52, thereby blocking the positioning block 31 and keeping the limiting rod 51 stable.

[0033] A first threaded groove 61 is formed through the inner wall of the limiting groove 4, and a second threaded groove 7, which communicates with the first threaded groove 61, is formed on the side wall of the base plate 1. The threaded rod 71 is threadedly connected to both the first threaded groove 61 and the second threaded groove 7. A placement groove 8 is formed on the side wall of the limiting rod 51 near the first threaded groove 61. A second inclined surface 81 is formed on the edge where the side wall of the placement groove 8 away from the compression spring 52 intersects with the side wall of the limiting rod 51 near the first threaded groove 61.

[0034] When the limiting rod 51 is connected to the limiting hole 6, in actual use, the limiting rod 51 may not be able to move to the farthest end due to tolerance. At this time, the operator only needs to rotate the threaded rod 71 to move the threaded rod 71 towards the limiting rod 51, thereby making the threaded rod 71 press against the second inclined surface 81. Under the action of the threaded rod 71, the limiting rod 51 continues to move towards the limiting hole 6, thereby pressing the limiting rod 51 against the inner wall of the limiting hole 6. This reduces the difficulty for the operator to install the limiting rod 51 and reduces the probability of the limiting rod 51 resetting under the action of external force.

[0035] A first connecting groove 82 is provided through the inner wall of the limiting groove 4, and a second connecting groove 83 is provided on the side wall of the bottom plate 1, which is connected to the first connecting groove 82. A third inclined surface 84 is provided on the edge where the side wall of the placement groove 8 near the compression spring 52 intersects with the side wall of the limiting rod 51 near the first threaded groove 61.

[0036] When the worker needs to remove the positioning block 31 due to misalignment during installation, the worker must separate the limiting rod 51 from the limiting hole 6. At this time, the worker needs to rotate the threaded rod 71 in the opposite direction to separate the threaded rod 71 from the second threaded groove 7. Further, the worker needs to connect the threaded rod 71 to the second connecting groove 83 and push the threaded rod 71 to press it against the third inclined surface 84, thereby separating the limiting rod 51 from the limiting hole 6 under the action of the threaded rod 71.

[0037] To reduce the difficulty for workers to rotate the threaded rod 71, a handle 85 is fixed to the end of the threaded rod 71. A sealing gasket 9 is provided on the second connecting groove 83 to close the second connecting groove 83. When the worker does not need to use the second connecting groove 83, the worker only needs to connect the sealing gasket 9 to the second connecting groove 83 to close the second connecting groove 83.

[0038] The working principle of the non-removable floor decking in this embodiment is as follows: When workers need to install the floor decking, they need to connect the lower chord steel bar 2 with the clamp 11 and the fixing block 12. This allows the lower chord steel bar 2 to be initially stabilized under the combined action of the clamp 11 and the fixing block 12. Subsequently, workers need to connect the positioning block 31 with the positioning groove 41. This allows the limiting component 5 to automatically limit the positioning block 31, thereby stabilizing the positioning block 31 and reducing the difficulty for subsequent workers to fix the positioning block 31.

All technical solutions falling within the scope of this utility model's concept are protected.
