Technical Field

[0001] The present invention relates to the technical field of flooring, in particular to a calcium sulfate flooring substrate. Background Art

[0002] Flooring refers to the covering or material used on the floor of indoor buildings, providing a protective layer for walking, support, and decoration. Flooring is typically made from a variety of materials, including wood, stone, ceramic tile, floor tiles, carpet, resilient flooring, and calcium sulfate flooring. Calcium sulfate flooring, also known as gypsum board or gypsum fiberboard, is a building material primarily made from gypsum. Different types of flooring materials have distinct characteristics and uses. Calcium sulfate board is widely used in construction, interior decoration, and furniture manufacturing, providing structural support, space division, and sound insulation. Currently, calcium sulfate flooring is complex to replace, and cracked calcium sulfate flooring can easily cause injury if not promptly addressed. Summary of the Invention

[0015] Preferably, the limit assembly includes a limit moving tooth block, two limit clamping rods and two limit abutment plates. A limit sliding groove matching the sliding rail is provided at the bottom of the limit moving tooth block.

[0019] The beneficial effects of the present invention compared to the prior art are:

[0020] 1. The pre-installed structure of the present invention can be recycled infinitely. The size of the calcium sulfate floor can be a square with a side length of 2 meters, for example, or 1 meter or 3 meters. If the calcium sulfate floor is damaged, the calcium sulfate floor can be directly taken out and replaced, which improves the convenience of replacement and installation. If the calcium sulfate floor is damaged due to external factors, if someone accidentally steps into the damaged calcium sulfate floor, the middle part of the calcium sulfate floor is likely to crack and collapse downward, which is likely to cause accidental injuries. However, in this case, the connection components, linkage components, limit components and movable components in the pre-installed structure are coordinated, so that when the middle part of the calcium sulfate floor cracks and has a tendency to collapse downward under pressure, the damaged calcium sulfate floor can be lifted up to prevent it from further collapsing. It can also prevent people from stepping into the cracked calcium sulfate floor and getting injured, thereby improving safety and practicality.

[0021] 2. When the movable trigger block is moved a certain distance by the downward pressure, it will abut against the top of the limit support plate, so that the movable trigger block will not move further downward. It can prevent people who accidentally step into the damaged calcium sulfate floor from falling further downward, thereby protecting the safety of people who step into the damaged calcium sulfate floor and improving safety.

[0022] 3. When the movable trigger block is subjected to a large downward pressure, the support guide rod can press against the limit trigger baffle to flip upward. When the support guide rod passes over the limit trigger baffle, the limit abutment plate enters the limit abutment groove to press against the movable trigger block, preventing the movable trigger block from moving further downward. When the movable trigger block is subjected to a small downward pressure, the support guide rod presses against the limit trigger baffle to flip upward at a certain angle and stops. The support guide rod cannot pass over the limit trigger baffle, which can prevent people from stepping into the damaged calcium sulfate floor with a light force and provide a buffer.

[0023] 4. There is still a certain vertical distance between the top of the circular support block and the top of the movable trigger block, so the middle of the cracked calcium sulfate floor will still be concave at a certain angle, which makes it convenient for operators to take out the calcium sulfate floor for replacement, and also makes it convenient to observe that the calcium sulfate floor is damaged to prevent stepping on it again, thereby improving practicality and safety.

[0024] 5. The protective support block can support the cracked calcium sulfate floor and prevent it from further cracking and collapsing, thereby playing a protective role. The lifting of the protective support block can make the edge of the cracked calcium sulfate floor tilt upward, making it easier for operators to replace the new calcium sulfate floor.

[0025] 6. Liquid cannot flow out through the tiny holes due to surface tension. The buffer capsule is compressed to make the liquid spray out from the tiny holes. The sprayed liquid can increase the humidity in the air, so that the dust generated by the damaged calcium sulfate floor is mixed with water to improve its adhesion effect, preventing the dust generated when the calcium sulfate floor is damaged from splashing everywhere, affecting the subsequent cleaning work, and improving the sanitary environment.

The movable component 50 includes a movable trigger block 51, four limit trigger baffles 52 and four movable racks 53. Support guide grooves 511 are provided on the four side walls of the movable trigger block 51 opposite to the mounting shell 10. The movable trigger block 51 is slidably set on the four support guide rods 215 through the four support guide grooves 511. The four limit trigger baffles 52 are respectively rotatably installed on the four side walls of the movable trigger block 51 opposite to the mounting shell 10 through torsion springs, and the bottom of the limit trigger baffle 52 is against the top of the support guide rod 215.

[0048] The movable trigger block 51 is provided with a limiting abutment groove 512 on the four side walls opposite to the mounting shell 10. The limiting abutment groove 512 is located between the support guide groove 511 and the movable rack 53 on the same side wall. The limiting movable tooth block 41 can enter the limiting abutment groove 512 when the movable trigger block 51 moves away from the calcium sulfate floor 1, so that the limiting abutment plate 43 abuts against the top of the limiting abutment groove 512, preventing the movable trigger block 51 from moving further away from the calcium sulfate floor 1.

[0049] A buffer capsule 513 is fixedly installed on the top of the support guide groove 511, and a number of fine through holes 514 are provided on the four side walls of the movable trigger block 51 opposite to the mounting shell 10, and the fine through holes 514 on the same side wall are located above the limiting support groove 512. Four liquid storage chambers 515 are provided in the movable trigger block 51, and each liquid storage chamber 515 is interconnected with the number of fine through holes 514 on the same side wall. A connecting groove 516 is provided on the side wall of the liquid storage chamber 515 close to the buffer capsule 513, and an extrusion hole 517 is provided on the side wall of the buffer capsule 513 close to the liquid storage chamber 515, and the connecting groove 516 and the extrusion hole 517 are interconnected.

[0050] In one embodiment, the operator installs the manufactured calcium sulfate floor 1 on the top of the circular support block 13 and locates it in the floor installation groove 11. During the installation process of the calcium sulfate floor 1, the ground is generally processed first, and then the floor base is installed on the ground, and then the calcium sulfate floor is laid on the floor base. However, in this case, due to the provision of a pre-installed structure 2, the calcium sulfate floor 1 can be installed in the pre-installed structure 2. The pre-installed structure 2 can play a certain protective role for the calcium sulfate floor 1. The outer wall of the installation shell 10 is provided with an installation slot 12. In this case, the operator can install the installation shell 10 on the floor base through the installation slot 12, thereby improving the practicality of the installation. During the use of the calcium sulfate floor 1, If the calcium sulfate floor 1 is damaged, the calcium sulfate floor 1 can be directly taken out and replaced, which improves the convenience of replacement and installation. If the calcium sulfate floor 1 is damaged due to external factors, if someone accidentally steps on the damaged calcium sulfate floor 1, the middle part of the calcium sulfate floor 1 is likely to crack and collapse downward, which is likely to cause accidental injury. In this case, through the cooperation of the connection component 20, the linkage component 30, the limit component 40 and the movable component 50 in the pre-installed structure 2, when the middle part of the calcium sulfate floor 1 cracks and tends to collapse downward under pressure, the damaged calcium sulfate floor 1 can be lifted up to prevent it from further collapse. It can also prevent people from falling into the cracked calcium sulfate floor 1 and causing injury after stepping in, thereby improving safety and practicality.

[0051] In one embodiment, during use, when the calcium sulfate floor 1 is broken or cracked and about to break, if someone accidentally steps on the broken calcium sulfate floor 1, the broken calcium sulfate floor 1 is likely to collapse from the middle, causing harm to the trapped person. In this case, a movable trigger block 51 is provided. When the damaged calcium sulfate floor 1 is stepped on, the middle part of the calcium sulfate floor 1 can be depressed downward, thereby resisting the movable trigger block 51 and applying downward pressure to the movable trigger block 51, so that the movable trigger block 51 moves downward. When the movable trigger block 51 moves downward, it can drive the movable rack 53 to move downward. When the movable rack 53 moves downward, it can drive the meshed first linkage gear 34 to rotate. The first linkage gear 34 can drive the second linkage gear 36 to rotate, and the second linkage gear 36 can rotate. When the second linkage shaft 35 rotates, it can drive the third linkage gear 37 to rotate. When the third linkage gear 37 rotates, it can drive the limit movable tooth block 41 to move in the direction of the movable trigger block 51. When the limit movable tooth block 41 moves, it can drive the limit abutting plate 43 to move in the direction of the movable trigger block 51, so that the limit abutting plate 43 enters the limit abutting groove 512. After the movable trigger block 51 is subjected to downward pressure and moves for a certain displacement, it will abut against the top of the limit abutting plate 43, so that the movable trigger block 51 will not move further downward, which can prevent people who accidentally step into the damaged calcium sulfate floor 1 from falling further downward, thereby protecting the safety of people who step into the damaged calcium sulfate floor 1 and improving safety.

[0052] The four side walls of the movable trigger block 51 are provided with support guide grooves 511, and the support guide rods 215 are slidably set in the support guide grooves 511. When the movable trigger block 51 is subjected to pressure and moves downward, the movable trigger block 51 can be moved vertically downward under the guidance of the four support guide rods 215. The top of the support guide rod 215 abuts against the limit trigger baffle 52. When the movable trigger block 51 is subjected to a large downward pressure, the support guide rod 215 can abut against the limit trigger baffle 52 to flip upward. When the support guide rod 215 passes over the limit trigger baffle 52, the limit abutting plate 43 enters the limit abutting groove 512 to abut the movable trigger block 51, preventing the movable trigger block 51 from moving further downward. When the movable trigger block 51 is subjected to a small downward pressure, the support guide rod 215 abuts against the limit trigger baffle 52 to flip upward. After turning a certain angle, it stops, and the supporting guide rod 215 cannot go over the limit trigger baffle 52, which can prevent people from stepping into the damaged calcium sulfate floor 1 with a lighter force and provide buffering. After the movable trigger block 51 loses the downward pressure, the limit trigger baffle 52 is used to press the supporting guide rod 215 to reset through the action of the torsion spring, so that the movable trigger block 51 moves upward and resets, lifting the middle part of the cracked and sunken calcium sulfate floor 1, but the calcium sulfate floor 1 is still sunken at a certain angle. Because the vertical distance between the top of the circular support block 13 and the top of the movable trigger block 51 is still a certain distance, the middle part of the cracked calcium sulfate floor 1 will still be sunken downward at a certain angle, which is convenient for the operator to take out the calcium sulfate floor 1 for replacement, and also convenient for observing that the calcium sulfate floor 1 is damaged, preventing it from being stepped on again, thereby improving practicality and safety.

[0053] When the movable trigger block 51 is subjected to a large downward pressure, causing the supporting guide rod 215 to press against the limit trigger baffle 52 to flip upward, the movable rack 53 can drive the meshed first linkage gear 34 to rotate, and the first linkage gear 34 can drive the second linkage gear 36 to rotate. When the second linkage gear 36 rotates, it can drive the second linkage shaft 35 to rotate. When the second linkage shaft 35 rotates, it can drive the third linkage gear 37 to rotate. When the third linkage gear 37 rotates, it can drive the limit moving tooth block 41 to move in the direction of the movable trigger block 51. The movement of the limit moving tooth block 41 drives the two limit clamping rods 42 to move toward the movable trigger block 51. When the two limit rods 42 move away from the protective lifting groove 211, the two limit rods 42 no longer abut against the top of the anti-slip block 23, and the anti-slip block 23 moves upward under the action of the elastic force of the protective supporting spring 22. The anti-slip block 23 moves upward to drive the protective support column 24 to move upward, and the protective support column 24 drives the protective support block 241 to move upward. The protective support block 241 can support the cracked calcium sulfate floor 1 to prevent the calcium sulfate floor 1 from further cracking and collapsing downward, thereby playing a protective role, and the lifting of the protective support block 241 can make the edge of the cracked calcium sulfate floor 1 tilt upward, making it convenient for the operator to replace the new calcium sulfate floor 1.

[0054] In one embodiment, when the movable trigger block 51 is moved downward by pressure, the movable trigger block 51 can move downward along the end of the supporting guide rod 215, and the movable trigger block 51 can drive the buffer capsule 513 to move downward, and then abut against the end of the supporting guide rod 215, so that the end of the supporting guide rod 215 squeezes the buffer capsule 513, so that the buffer capsule 513 is compressed. Liquid is provided in the buffer capsule 513, the liquid storage chamber 515, the connecting groove 516 and the extrusion hole 517. The aperture of the fine through-hole 514 is small. The liquid cannot flow out through the fine through-hole 514 due to surface tension. The buffer capsule 513 is compressed so that the liquid is sprayed out from the fine through-hole 514. The sprayed liquid can increase the humidity in the air, so that the dust generated by the damaged calcium sulfate floor 1 is mixed with water to improve its adhesion effect, thereby preventing the dust generated when the calcium sulfate floor 1 is damaged from splashing everywhere, affecting the subsequent cleaning work, and improving the sanitary environment.

[0055] In one embodiment, under normal circumstances, when the movable trigger block 51 has not yet received the downward pressure of the damaged calcium sulfate floor 1, the horizontal height of the top of the movable trigger block 51 is higher than the horizontal height of the top of the protective support block 241, that is, when the damaged calcium sulfate floor 1 collapses, pressure is first applied to the movable trigger block 51 to make the movable trigger block 51 move downward, and during the movement, the protective support block 241 moves upward through the cooperation of the connecting component 20, the linkage component 30 and the limit component 40, and then the horizontal height of the top of the protective support block 241 is higher than the horizontal height of the top of the movable trigger block 51.

[0056] In another embodiment, a drainage slope is formed on the top of the circular support block 13, and the distance between the drainage slope and the bottom surface of the circular support block 13 gradually decreases toward the movable trigger block 51. When water accumulates on the top of the calcium sulfate floor 1, it can flow out downward along the drainage slope. Water storage guide pipes are provided on the four edges of the drainage slope, and the water storage guide pipes are connected to the liquid storage chamber 515. A one-way valve is installed inside the end of the water storage guide pipe close to the liquid storage chamber 515, so that part of the accumulated water flowing downward on the drainage slope flows into the liquid storage chamber 515 through the water storage guide pipe to replenish the moisture in the liquid storage chamber 515.

The bottom of the limit movable gear block 41 is provided with a limit sliding groove 411 matching the sliding rail 213. The two limit clamping rods 42 are fixedly mounted on the side of the limit movable gear block 41 facing the connecting mounting block 21. The two limit abutment plates 43 are fixedly mounted on both sides of the top of the limit movable gear block 41. The movable trigger block 51 is slidably set on the four support guide rods 215 through four support guide grooves 511. The four limit trigger baffles 52 are respectively rotatably mounted on the four side walls of the movable trigger block 51 opposite to the mounting shell 10 through torsion springs. The four movable racks 53 are respectively fixedly mounted on the four side walls of the movable trigger block 51 opposite to the mounting shell 10.

[0058] For example, the present invention also provides a pre-installed structure of the above-mentioned calcium sulfate floor substrate.

[0059] Beneficial effects: 1. If the calcium sulfate floor 1 is damaged, the calcium sulfate floor 1 can be directly taken out and replaced, which improves the convenience of replacement and installation. When the calcium sulfate floor 1 is damaged due to external factors, if someone accidentally steps on the damaged calcium sulfate floor 1, the middle part of the calcium sulfate floor 1 is likely to crack and collapse downward, which is likely to cause accidental injury. In this case, through the cooperation of the connection component 20, the linkage component 30, the limit component 40 and the movable component 50 in the pre-installed structure 2, when the middle part of the calcium sulfate floor 1 cracks and tends to collapse downward under pressure, the damaged calcium sulfate floor 1 can be lifted up to prevent it from further collapse. It can also prevent people from falling into the cracked calcium sulfate floor 1 and causing injury after stepping in, thereby improving safety and practicality.

[0060] 2. After the movable trigger block 51 is moved a certain distance by the downward pressure, it will abut against the top of the limit abutting plate 43, so that the movable trigger block 51 will not move further downward, which can prevent people who accidentally step into the damaged calcium sulfate floor 1 from falling further downward, thereby protecting the safety of people who step into the damaged calcium sulfate floor 1 and improving safety.

[0061] 3. When the movable trigger block 51 is subjected to a large downward pressure, the support guide rod 215 can press against the limit trigger baffle 52 to flip upward. When the support guide rod 215 passes over the limit trigger baffle 52, the limit abutting plate 43 enters the limit abutting groove 512 to press against the movable trigger block 51, preventing the movable trigger block 51 from moving further downward. When the movable trigger block 51 is subjected to a small downward pressure, the support guide rod 215 presses against the limit trigger baffle 52 to flip upward at a certain angle and stops. The support guide rod 215 cannot pass over the limit trigger baffle 52, which can prevent people from stepping into the damaged calcium sulfate floor 1 with a relatively light force and provide a buffer.

[0062] 4. The vertical distance between the top of the circular support block 13 and the top of the movable trigger block 51 is still a certain distance, so the middle part of the cracked calcium sulfate floor 1 will still be concave downward at a certain angle, which makes it convenient for operators to take out the calcium sulfate floor 1 for replacement, and also makes it convenient to observe that the calcium sulfate floor 1 is damaged and prevent people from stepping on it again, thereby improving practicality and safety.

[0063] 5. The protective support block 241 can support the cracked calcium sulfate floor 1 and prevent the calcium sulfate floor 1 from further cracking and collapsing, thereby playing a protective role. The lifting of the protective support block 241 can make the edge of the cracked calcium sulfate floor 1 tilt upward, making it easier for operators to replace the new calcium sulfate floor 1.

[0064] 6. Since the liquid cannot flow out through the fine through-holes 514 due to surface tension, the buffer capsule 513 is compressed, causing the liquid to be sprayed out from the fine through-holes 514. The sprayed liquid can increase the humidity in the air, so that the dust generated by the damaged calcium sulfate floor 1 mixes with the water to improve its adhesion effect, preventing the dust generated when the calcium sulfate floor 1 is damaged from splashing everywhere and affecting the subsequent cleaning work, thereby improving the sanitary environment.

[0065] For example, in another embodiment, the present invention further provides a calcium sulfate floor comprising the above-mentioned calcium sulfate floor substrate and the above-mentioned pre-assembled structure. The above-mentioned calcium sulfate floor substrate comprises the following raw materials: calcium sulfate, paper fiber, wood fiber, water, polyester resin, polyurethane, and pigment. The preparation steps of the calcium sulfate floor include:

[0066] Step 1: Calcium sulfate, paper fiber, and wood fiber are added into a blender in a mass ratio of 12:4:1, stirred at 1000 rpm for 15 minutes, and heated at 10°C / min. When the temperature reaches 90°C, heating is stopped, and the mixture is naturally cooled to room temperature to form a mixture;

[0067] Step 2: Put the mixture, water, polyester resin, polyurethane and pigment into a blender, stir evenly, then pour it into the floor mold, level the surface and remove bubbles;

[0068] Step 3: Pre-press the floor mold with a pre-pressing machine at 3 MPa; then send it into a hot press for hot pressing at a temperature of 160°C and a pressure of 14 MPa to form a calcium sulfate floor substrate;

[0069] Step 4: Take out the calcium sulfate floor substrate for finishing and trimming, and install the finished calcium sulfate floor substrate on the pre-installed structure 2 to form the calcium sulfate floor.

[0070] All possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above-described embodiments merely represent several embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art can make a variety of modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of the present invention. Therefore, the scope of the present invention's patent shall be based on the appended claims.
