[0010] As a preferred embodiment of the easily removable steel truss floor deck of the present invention, the limiting component includes a support platform disposed on the distribution rod, a limiting groove opened outside the support platform, and a positioning rod disposed in the limiting groove;

[0011] The limiting groove is matched with the distribution rod, and the positioning rod is connected to the distribution rod.

[0012] As a preferred embodiment of the easily removable steel truss floor decking of the present invention, the sliding assembly includes a connecting rod connected to the support platform and a sliding rod connected to the end of the connecting rod.

[0013] As a preferred embodiment of the easily removable steel truss floor decking of the present invention, the installation assembly includes an installation plate disposed outside the slide bar, a slide groove formed inside the installation plate, and an installation hole formed outside the installation plate;

[0014] The groove is matched with the slide rod.

[0015] As a preferred embodiment of the easily removable steel truss floor decking of the present invention, the output assembly includes an output rod connected to the slide rod, an output plate connected to the end of the output rod, and a force-bearing rod disposed outside the output rod;

[0016] The force-bearing rod is matched with the reset groove.

[0017] As a preferred embodiment of the easily removable steel truss floor slab described in this invention, it further includes load-bearing components;

[0018] The force-bearing component includes a distribution component connected to the sliding component, a bearing component disposed under the distribution component, and a tilting component disposed outside the bearing component;

[0019] The load-bearing component is connected to the support component.

[0020] As a preferred embodiment of the steel truss floor deck that is easy to dismantle according to the present invention, the sharing component includes a slider, a limiting rod disposed in the slider, and a reset spring disposed between the slider and the reset groove outside the limiting rod.

[0021] The slider is connected to the force-bearing rod, the slider is located in the reset groove, and the limiting rod is located in the reset groove.

[0022] As a preferred embodiment of the easily removable steel truss floor decking of the present invention, the load-bearing component includes a convex plate and a rotating rod connected to the convex plate;

[0023] The convex plate is connected to the bottom of the support plate.

[0025] The beneficial effects of this invention are as follows: First, the device is fixed in the designated position through the mounting holes on both sides of the mounting plate. Then, the truss floor deck is placed on the support platform, and the weight of the steel truss floor deck causes the support platform to descend. Then, the positioning rod in the limiting groove positions the distribution rod, allowing the bottom ends of a pair of distribution rods to move to both sides in the limiting groove and abut against the edge of the limiting groove. This allows a portion of the vertical load to be converted into a longitudinal load. In addition, during the descent of the support platform, the output plate is also driven to descend, pressing the two side rocker arms. The position of the rotating rod near the counterweight block forms a simple lever. When the output plate presses the two side rocker arms, it is easier to release the lifting force exceeding the pressing force, thereby causing the L-shaped convex rod to abut against the bottom of the wall and forming an upward lifting force. This relieves the pressure on the screws from the device, preventing the screws from falling off due to excessive load. Attached Figure Description

[0037] Example 1

[0038] Reference Figures 1-3 A schematic diagram of an overall structure for a steel truss floor slab that is easy to dismantle is provided, including:

[0039] The main component 100 includes a support assembly 101, a limiting assembly 102 disposed on the support assembly 101, and a sliding assembly 103 connected to the limiting assembly 102; the force-bearing component 200 includes an installation assembly 201 disposed outside the sliding assembly 103, and an output assembly 202 disposed inside the installation assembly 201. The support assembly 101 is for supporting the limiting assembly 102, and thus supporting the truss floor deck through the limiting assembly 102. The sliding assembly 103 is for enabling the limiting assembly 102 to have a lifting function. The installation assembly 201 enables the device to be installed easily, and at the same time, the sliding assembly 103 can provide power to the output assembly 202 while moving.

[0040] Specifically, the support assembly 101 includes a support plate 101a, a limiting groove 101b formed on the support plate 101a, a distribution rod 101c disposed in the limiting groove 101b, and a reset groove 101d formed on the support plate 101a. A pair of limiting grooves 101b are formed on one side of the top of the support plate 101a, and the distribution rod 101c is slidably connected inside the pair of limiting grooves 101b. A pair of reset grooves 101d are formed on the other side of the top of the support plate 101a.

[0041] Furthermore, the limiting component 102 includes a support platform 102a disposed on the distribution rod 101c, a limiting groove 102b formed outside the support platform 102a, and a positioning rod 102c disposed within the limiting groove 102b; wherein, the limiting groove 102b matches the distribution rod 101c, the positioning rod 102c is connected to the distribution rod 101c, the support platform 102a is disposed on the upper side of the support plate 101a, the bottom end of the support platform 102a is provided with the limiting groove 102b at the position of the distribution rod 101c, and the positioning rod 102c is rotatably connected inside the limiting groove 102b. The outer side of the positioning rod 102c is fixedly connected to one end of the inner side of the distribution rod. When the truss floor plate is placed on the support platform 102a, the support platform 102a will descend under the weight of the truss floor plate. Then, the positioning rod 102c in the limiting groove 102b will position the distribution rod 101c. This will allow the bottom ends of the pair of distribution rods 101c to move to both sides in the limiting groove 101b and abut against the edge of the limiting groove 101b. This will convert a part of the vertical load into a longitudinal load and transfer it to the support plate 101a.

[0042] Furthermore, the sliding assembly 103 includes a connecting rod 103a connected to the support platform 102a and a sliding rod 103b connected to the end of the connecting rod 103a. The mounting assembly 201 includes a mounting plate 201a disposed outside the sliding rod 103b, a groove 201b formed in the mounting plate 201a, and a mounting hole 201c formed outside the mounting plate 201a. The groove 201b matches the sliding rod 103b. The support plate 101a is fixedly connected to the mounting plate 201a above one end of the reset groove 101d. Mounting holes 201c are formed on both sides of the mounting plate 201a. A through groove 201b is formed inside the mounting plate 201a. The sliding rod 103b is slidably connected inside the groove 201b. Connecting rods 103a are fixedly connected to both sides of the top. The top ends of the connecting rods 103a on both sides are fixedly connected to the bottom end of the support platform 102a. The device is fixed in the designated position through the mounting holes 201c on both sides of the mounting plate 201a and screws. Then, the truss floor deck is placed on the support platform 102a. When the support platform 102a is lowered by gravity, it can drive the connecting rods 103a and the sliding rods 103b to descend. When the support platform 102a descends to contact the support plate 101a, it stops descending and is supported by the mounting plate 201a. At the same time, in conjunction with the aforementioned load-sharing rods 101c, it can transfer the load and also support the other side of the bottom end of the support platform 102a, thereby increasing its support stability.

[0043] Operation process: First, the device is fixed in the designated position through the mounting holes 201c on both sides of the mounting plate 201a and screws. Then, the truss floor deck is placed on the support platform 102a. Under the weight of the truss floor deck, the support platform 102a will descend. Then, the positioning rods 102c in the limiting groove 102b will position the distribution rods 101c. This allows the bottom ends of the pair of distribution rods 101c to move to both sides in the limiting groove 101b and abut against the edge of the limiting groove 101b. This allows a portion of the vertical load to be converted into a longitudinal load and transferred to the support plate 101a. As the support platform 102a descends, it also drives the connecting rod 103a and the sliding rod 103b to descend. When the support platform 102a descends to contact the support plate 101a, it stops descending and is supported by the mounting plate 201a. In conjunction with the aforementioned load-sharing rod 101c, it not only transfers the load but also supports the other side of the bottom of the support platform 102a, thereby increasing its stability.

[0044] Example 2

[0045] Reference Figures 1-5 This embodiment differs from the first embodiment in that: the output component 202 includes an output rod 202a connected to the slide rod 103b, an output plate 202b connected to the end of the output rod 202a, and a force-receiving rod 202c disposed outside the output rod 202a; wherein, the force-receiving rod 202c matches the reset groove 101d, the output rod 202a is fixedly connected to the middle of the bottom end of the slide rod 103b, the bottom end of the output rod 202a passes through the support plate 101a and is fixedly connected to the output plate 202b, and the force-receiving rods 202c are rotatably connected to both sides of the rod body of the output rod 202a. When the slide rod 103b descends, it also drives the output rod 202a and the output plate 202b to descend, and provides power to the bottom mechanism.

[0046] Specifically, it also includes a force-bearing component 300; the force-bearing component 300 includes a sharing component 301 connected to the sliding component 103, a bearing component 302 disposed below the sharing component 301, and a tilting component 303 disposed outside the bearing component 302; wherein, the bearing component 302 is connected to the support component 101, the sharing component 301 is for resetting when the above structure loses the pressure of the truss floor plate, and the bearing component 302 is for supporting the next sharing mechanism.

[0047] The further distribution component 301 includes a slider 301a, a limiting rod 301b disposed within the slider 301a, and a return spring 301c disposed between the slider 301a and the return groove 101d outside the limiting rod 301b. The slider 301a is connected to the force-bearing rod 202c. The slider 301a is disposed within the return groove 101d, and the limiting rod 301b is disposed within the return groove 101d. Limiting rods 301b are fixedly connected inside both return grooves 101d. Sliding sliders 301a are slidably connected to the outer sides of both limiting rods 301b. The sliders 301a slide within the return grooves 101d. Both sliders 301a are rotatably connected to both force-bearing rods 202c. The return spring 301c is sleeved on the outer sides of the two limiting rods 301b between the slider 301a and the return groove 101d. When the output rod 202a descends, it drives the force-bearing rod 202c. As the device descends, its bottom ends cause the sliders 301a on both sides to move in opposite directions within the reset groove 101d. Simultaneously, a portion of the vertical load is transferred to the reset groove 101d. During the movement of the sliders 301a, the reset spring 301c is compressed. When the device is disassembled, the support platform 102a loses the pressure from the truss floor plate, and the rebound force of the reset spring 301c is greater than the external force. This allows the reset spring 301c to reset while simultaneously causing the slider 301a to reset. The slider 301a then causes the bottom end of the force-bearing rod 202c to move in a similar direction, lifting the output rod 202a. This resets the sliding rod 103b, connecting rod 103a, and support plate 101a, thus achieving the reset function when the device loses the pressure from the truss floor plate.

[0048] The rest of the structure is the same as in Example 1.

[0049] Operation process: As the output rod 202a descends, it drives the force-bearing rod 202c to descend as well. At the same time, the bottom ends of the force-bearing rod 202c move the sliders 301a on both sides in the reset groove 101d in opposite directions. Simultaneously, a portion of the vertical load is transferred to the reset groove 101d. During the movement of the slider 301a, the reset spring 301c is also compressed. When the device is disassembled, the support platform 102a loses the pressure from the truss floor plate. At the same time, the rebound force of the reset spring 301c is greater than the external force applied to it. This allows the reset spring 301c to reset, driving the slider 301a to reset. Consequently, the slider 301a also drives the bottom end of the force-bearing rod 202c to move in a similar direction, while simultaneously lifting the output rod 202a. This allows the sliding rod 103b, connecting rod 103a, and support plate 101a to reset, thus achieving the purpose of resetting the device when the pressure from the truss floor plate is lost.

[0050] Example 3

[0051] Reference Figures 1-6 This embodiment differs from the above embodiments in that: the supporting component 302 includes a convex plate 302a and a rotating rod 302b connected to the convex plate 302a; wherein, the convex plate 302a is connected to the bottom of the support plate 101a, the bottom end of the support plate 101a is fixedly connected to the convex plate 302a, and the rotating rods 302b are rotatably connected to both sides of one end of the convex plate 302a.

[0052] Furthermore, the tilting assembly 303 includes a tilting rod 303a disposed outside the rotating rod 302b, an L-shaped protrusion 303b connected to the tilting rod 303a, and a counterweight 303c connected to the L-shaped protrusion 303b. The ends of the two tilting rods 303a that are far apart are fixedly connected to the rotating rod 302b. The ends of the two tilting rods 303a that are far apart are both fixedly connected to the L-shaped protrusion 303b. The bottom ends of the two L-shaped protrusions 303b are both fixedly connected to the counterweight 303c. When the output rod 202a descends, it also drives the output plate 202b to descend, and at the same time, it presses down on the ends of the two tilting rods 303a that are close together. By positioning the rotating rod 302b close to one end of the counterweight 303c, a simple lever can be formed. This allows for easier lifting of the levers 303a on both sides when the output plate 202b presses down, releasing a lifting force exceeding the pressing force. This causes the L-shaped protrusion 303b to contact the bottom of the wall, creating an upward lifting force. This relieves the pressure on the screws, preventing them from falling off due to excessive load. When the output rods 202a and the output plate 202b are reset, the counterweight 303c can also reset the levers 303a.

[0053] Operation process: As the slide bar 103b descends, it also lowers the output rod 202a and the output plate 202b. Simultaneously, it presses down on the ends of the two rocker arms 303a. The position of the rotating rod 302b near the counterweight 303c creates a simple lever. This allows the output plate 202b to press down on the rocker arms 303a with less effort and releases a lifting force exceeding the pressing force. This causes the L-shaped protrusion 303b to contact the bottom of the wall, creating an upward lifting force. This relieves the pressure on the screw, preventing it from falling off due to excessive load. When the structure resets the output rod 202a and the output plate 202b, the counterweight 303c resets the rocker arms 303a.
