Abstract
Description
Technical Field
[0001] This invention relates to the field of flooring construction technology, and in particular to an anti-cracking flooring and its construction method. Background Technology
[0002] Flooring refers to the treatment of existing ground using specific materials and processes to achieve certain decorative and functional properties. Examples include epoxy self-leveling flooring, emery abrasion-resistant flooring, epoxy terrazzo flooring, cement-based terrazzo flooring, epoxy colored sand flooring, epoxy anti-static flooring, epoxy anti-slip flooring, polyurea anti-corrosion flooring, polyurethane flooring, silicone PU flooring, and concrete sealing and curing agent flooring, etc.
[0003] Over long-term use, flooring may crack. The causes of flooring cracks include thermal expansion and contraction, uneven support due to hollow areas, and inadequate humidity control. Generally, the only way to reduce the chance of flooring cracks during the pouring process is to distribute the concrete evenly. However, there is no good way to deal with thermal expansion and contraction caused by temperature. Summary of the Invention
[0004] This invention discloses an anti-cracking floor and its construction method, aiming to solve the technical problem that in general, the probability of floor cracking can only be reduced by uniformly distributing concrete during the floor pouring process, but there is no good way to deal with the thermal expansion and contraction caused by temperature.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A crack-resistant floor includes a second concrete pouring layer, a first concrete pouring layer is laid on top of the second concrete pouring layer, an outer coating layer is laid on top of the first concrete pouring layer, and multiple support mechanisms are simultaneously provided between the first concrete pouring layer and the second concrete pouring layer.
[0007] Multiple support mechanisms include support tubes, and the support tubes are made entirely of glass. The support tubes include multiple arc-shaped connection ports arranged in a circular pattern with equal density. A TPU film is fixedly connected to the recess of each arc-shaped connection port.
[0008] A central support rod is fixedly connected to the inner wall of the bottom end of each support pipe, and an insertion hole is provided on the inner wall of the top end of the central support rod. An insertion rod is inserted into the insertion hole, and a locking block is fixedly connected to the top end of the insertion rod. A widening support plate is fixedly connected to the top end of the locking block, and the widening support plate is located inside the first concrete pouring layer.
[0009] Each support tube has a limit ring fixed to its top outer wall, and the locking block is engaged inside the limit ring.
[0010] By incorporating a support mechanism evenly distributed throughout the second concrete pouring layer, once the second concrete pouring layer has hardened, all locations except the curved joints are connected to the concrete. At this point, striking the curved joints causes them to break, eliminating the lateral support effect of the support pipes and providing internal gaps to compensate for thermal expansion and contraction. Furthermore, after the flooring construction is completed, the first concrete pouring layer is poured onto the top of the widened support plate, supported by a central strut, increasing its support area and providing effective support for the floor surface. During the hardening process of the second concrete pouring layer, the hardening status of the concrete can be detected by using a hook-like tool inserted between the curved joint and the TPU film, facilitating the timing of concrete curing. Thus, the anti-cracking effect of the flooring can be optimized in three aspects: providing space to compensate for thermal expansion and contraction, assisting in concrete curing, and providing effective support.
[0011] In a preferred embodiment, each of the support tubes is provided with an airbag, and the airbag is located between the arc-shaped connection port and the central support rod. Multiple curved grooves are irregularly distributed inside the airbag.
[0012] A method for constructing crack-resistant flooring includes the following specific steps:
[0013] S1: Ground cleaning and leveling;
[0014] S2: Concrete pouring: Measure the height and mark the location on the wall, pour concrete to form a second concrete pouring layer of fixed height;
[0015] S3: Insertion of support mechanism: Use the limiting mechanism to fix multiple support mechanisms at the same time, and insert the multiple support mechanisms into the uncured second concrete pouring layer;
[0016] S4: Break the support tube: Use the limiting mechanism to hold down multiple arc-shaped connection points in the support tube, and break the arc-shaped connection points by knocking.
[0017] S5: Rough grinding of the ground: After the second concrete pouring layer has set and hardened, rough grind the surface of the second concrete pouring layer and remove the dust generated during the grinding process.
[0018] In step S5, during the ground roughening process and dust cleaning process, the accumulated dust passes through the top of the support tube and enters the interior. At this time, some of the dust inside the support tube is injected into the multiple curved grooves inside the airbag.
[0019] By injecting the polished dust into the support tube, the airbags, regardless of their material, will leak during long-term use, significantly reducing their effectiveness. During cleaning, the dust enters the airbag and is irregularly filled within the curved grooves of the airbag and the support tube. When the airbag deflates, the dust provides support to the gaps, thus mitigating the internal stress of the airbag and ensuring long-term crack resistance for the flooring.
[0020] In a preferred embodiment, S5, after rough grinding of the ground, also includes the following specific steps:
[0021] S6: Cover the widened support plate: Insert the locking block into the limiting ring, insert the rod into the insertion hole, so that the widened support plate covers the top of the support tube;
[0022] S7: Secondary concrete pouring: Pour concrete again to cover the top of the widened support plate, and then smooth and grind it.
[0023] S8: Coating Covering: Cover the top of the first concrete pouring layer after grinding with the outer coating, and complete the floor construction after the outer coating is completely dry;
[0024] In the second concrete pouring process, the concrete poured around the widened support plate needs to be vibrated to allow the concrete to enter between the bottom of the widened support plate and the top of the second concrete pouring layer.
[0025] The limiting mechanism used in the insertion support mechanism in S3 includes two multi-headed bent rods, and a crossbar is connected between the two multi-headed bent rods. An impact plate is fixedly connected to the top outer wall of the crossbar, and handles are fixed to the opposite outer walls of the crossbar.
[0026] The two multi-headed bending rods each include multiple rod heads, and a circular support plate is fixedly connected to the bottom outer wall of each rod head. The outer wall of the circular support plate is wrapped with a rubber ring, and multiple conical heads are provided at the bottom of the circular support plate.
[0027] By setting a limiting mechanism, multiple support mechanisms can be inserted and limited simultaneously, improving work efficiency. In addition, when the support tube is struck, a limiting mechanism is installed again at the top of multiple support tubes to align the conical head with the arc-shaped connection. By using a hammer to strike the impact plate, and through the transmission of the multi-headed bent rod and crossbar, multiple support tubes can be directly and synchronously crushed, further improving construction efficiency and reducing construction difficulty.
[0028] As described above, an anti-cracking flooring and its construction method include a second concrete pouring layer, a first concrete pouring layer laid on top of the second concrete pouring layer, an outer coating layer laid on top of the first concrete pouring layer, and multiple support mechanisms simultaneously provided between the first and second concrete pouring layers. Each support mechanism includes a support pipe, which is entirely made of glass. The support pipe includes multiple arc-shaped connecting ports arranged in equal density, and a TPU film is fixedly connected to the recess of each arc-shaped connecting port. A central support rod is fixedly connected to the inner wall of the bottom end of each support pipe, and an insertion hole is provided on the inner wall of the top end of the central support rod. An insertion rod is inserted into the insertion hole, and a locking block is fixedly connected to the top end of the insertion rod. A widening support plate is fixedly connected to the top end of the locking block, and the widening support plate is located within the first concrete pouring layer. A limiting ring is fixedly fixed to the outer wall of the top end of each support pipe, and the locking block is engaged within the limiting ring. The anti-cracking flooring and its construction method provided by this invention have the technical effect of optimizing the anti-cracking function of the flooring in three aspects: providing space to offset thermal expansion and contraction, assisting in concrete curing, and providing effective support.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0038] The anti-cracking flooring and its construction method disclosed in this invention are mainly applied to flooring construction scenarios.
[0039] Reference Figures 1-4 A crack-resistant floor includes a second concrete pouring layer 3, a first concrete pouring layer 2 is laid on the top of the second concrete pouring layer 3, an outer coating layer 1 is laid on the top of the first concrete pouring layer 2, and multiple support mechanisms 4 are provided between the first concrete pouring layer 2 and the second concrete pouring layer 3.
[0040] Multiple support mechanisms 4 include support tubes 406, and the support tubes 406 are made of glass. The support tubes 406 include multiple arc-shaped connection ports 408 arranged in a circular pattern with equal density. A TPU film 407 is fixedly connected to the recess of each arc-shaped connection port 408.
[0041] A central support rod 409 is fixedly connected to the inner wall of the bottom end of each support pipe 406, and an insertion hole 410 is provided on the inner wall of the top end of the central support rod 409. An insertion rod 403 is inserted into the insertion hole 410, and a locking block 402 is fixedly connected to the top end of the insertion rod 403. A widening support plate 401 is fixedly connected to the top end of the locking block 402. The widening support plate 401 is located inside the first concrete pouring layer 2.
[0042] Each support tube 406 has a limiting ring 405 fixed to its top outer wall, and a locking block 402 is engaged within the limiting ring 405. By evenly distributing the support mechanism 4 in the second concrete pouring layer 3, the support tube 406 acts as a support. Under the obstruction of the TPU film 407, the arc-shaped connection port 408 is prevented from directly contacting the concrete. After the second concrete pouring layer 3 hardens, all positions except the arc-shaped connection port 408 are connected to the concrete. At this time, by striking the arc-shaped connection port 408 to break it, the lateral support effect of the support tube 406 can be eliminated, providing the internal gap of the support tube 406 as a space to offset thermal expansion and contraction. Over time, the TPU film will lose its binding force. After the floor construction is completed, the first concrete pouring layer 2 is poured on the top of the widened support plate 401, supported by the central support rod 409, which increases the support area and provides effective support for the floor surface. During the hardening process of the second concrete pouring layer 3, the hardening condition of the concrete can be detected by using a hook-like tool to pass through the position between the arc-shaped connection 408 and the TPU film 407, which makes it easier to grasp the timing of concrete curing. Thus, the anti-cracking effect of the floor can be optimized in three aspects: providing space to offset thermal expansion and contraction, assisting concrete curing, and providing effective support.
[0043] Reference Figure 4 and Figure 5 In a preferred embodiment, each support tube 406 is provided with an airbag 404, and the airbag 404 is located between the arc-shaped connection port 408 and the central support rod 409. Multiple curved grooves 411 are irregularly distributed inside the airbag 404.
[0044] Reference Figure 7 A method for constructing crack-resistant flooring includes the following specific steps:
[0045] S1: Ground cleaning and leveling;
[0046] S2: Concrete pouring: Measure the height and mark the location on the wall, pour concrete to form a second concrete pouring layer 3 with a fixed height;
[0047] S3: Inserting support mechanism: Using a limiting mechanism to simultaneously fix multiple support mechanisms 4, and inserting multiple support mechanisms 4 into the uncured second concrete pouring layer 3;
[0048] S4: Break the support tube: Use the limiting mechanism to hold the multiple arc-shaped connection ports 408 in the support tube 406, and break the arc-shaped connection ports 408 by knocking.
[0049] S5: Rough grinding of the ground: After the second concrete pouring layer 3 has set and hardened, rough grind the surface of the second concrete pouring layer 3 and remove the dust generated during the grinding process.
[0050] Reference Figure 3 , Figure 4 and Figure 7 In a preferred embodiment, S5, during the ground roughening and dust removal process, the accumulated dust passes through the top of the support tube 406 and enters its interior. At this time, some of the dust inside the support tube 406 is injected into the multiple curved grooves 411 inside the airbag 404. By injecting the ground dust into the support tube 406, the airbag 404 inside the support tube 406 acts as a countermeasure against the internal stress caused by the thermal expansion and contraction of the concrete after the support tube 406 is broken. Regardless of the material of the airbag 404, it will remain in place for a long time. During use, air leakage will occur. After a period of use, the effectiveness of the airbag 404 will be greatly reduced. By allowing dust to enter the airbag 404 during cleaning, the dust is irregularly filled into the curved grooves 411 inside the airbag 404 and into the support tube 406 through irregular curved grooves 411. When the airbag 404 deflates, the gaps left will be supported by the dust. Thus, the dust replaces the internal stress of the airbag 404 to offset the effect, ensuring the long-term anti-cracking effect of the floor.
[0051] Reference Figure 7 In a preferred embodiment, step S5, after rough grinding of the ground, further includes the following specific steps:
[0052] S6: Cover the widened support plate: Insert the locking block 402 into the limiting ring 405, insert the insertion rod 403 into the insertion hole 410, so that the widened support plate 401 covers the support tube 406.
[0053] S7: Secondary concrete pouring: Pour concrete again to cover the top of the widened support plate 401, and then smooth and grind it.
[0054] S8: Coating Covering: Cover the top of the first concrete pouring layer 2 after grinding with outer coating 1. After the outer coating 1 is completely dry, the floor construction is completed.
[0055] Reference Figure 7 In a preferred embodiment, S7, during the secondary concrete pouring process, the concrete poured around the widened support plate 401 needs to be vibrated so that the concrete enters between the bottom end of the widened support plate 401 and the top end of the second concrete pouring layer 3.
[0056] Reference Figure 6 In a preferred embodiment, S3, the limiting mechanism used in the insertion support mechanism includes two multi-headed bent rods 501, and a crossbar 503 is connected between the two multi-headed bent rods 501. An impact plate 504 is fixedly connected to the top outer wall of the crossbar 503, and handles 502 are fixedly fixed to the opposite outer walls of the crossbar 503.
[0057] Reference Figure 6 In a preferred embodiment, the two multi-headed curved rods 501 each include multiple rod heads 506. A circular support plate 507 is fixedly connected to the outer wall of the bottom end of each rod head 506. A rubber ring 505 covers the outer wall of the circular support plate 507. Multiple conical heads 508 are also provided at the bottom end of the circular support plate 507. A limiting mechanism is used when placing the support mechanism 4 and when breaking the support tube 406. The limiting mechanism is engaged with the multiple circular support plates 507 and the externally wrapped rubber ring 505. Multiple support mechanisms can be picked up simultaneously within ring 405, thereby enabling the simultaneous insertion and limiting of multiple support mechanisms 4, improving work efficiency. In addition, when the support tube 406 is struck, a limiting mechanism is installed again at the top of multiple support tubes 406, so that the conical head 508 is aligned with the arc-shaped connection port 408. By using a hammer to strike the impact plate 504, and through the transmission of the multi-headed bent rod 501 and the crossbar 503, multiple support tubes 406 can be directly and synchronously crushed, further improving construction efficiency and reducing construction difficulty.
[0058] Working principle: During construction, the support mechanism 4 is evenly distributed in the second concrete pouring layer 3. At this time, the support pipe 406 acts as a support, and under the obstruction of the TPU film 407, the curved joint 408 is prevented from directly contacting the concrete. After the second concrete pouring layer 3 hardens, all positions except the curved joint 408 are connected to the concrete. At this time, by tapping the curved joint 408 to break it, the lateral support effect of the support pipe 406 can be eliminated, and the internal gap of the support pipe 406 can be used as a space to offset thermal expansion and contraction. At the same time, the TPU film will lose its restraining force over long-term use, and after the floor construction is completed, the first concrete pouring layer... 2. The concrete is poured onto the top of the widened support plate 401, supported by the central support rod 409, increasing its support area and providing effective support for the floor surface. During the hardening process of the second concrete pouring layer 3, the hardening condition of the concrete can be detected by using a hook-like tool to pass through the position between the arc-shaped connection 408 and the TPU film 407, making it easier to grasp the timing of concrete curing. Thus, the anti-cracking effect of the floor can be optimized in three aspects: providing space to offset thermal expansion and contraction, assisting concrete curing, and providing effective support. In addition, by injecting the grinding dust into the support pipe 406, the air bladder 404 inside the support pipe 406 is ruptured. This system helps to counteract the internal stress caused by the thermal expansion and contraction of concrete. However, regardless of the material, airbags 404 will leak during long-term use, significantly reducing their effectiveness. During cleaning, dust enters the airbag 404 and is irregularly filled within the curved grooves 411 and the support tube 406. When the airbag 404 deflates, the dust provides some support to the gaps, thus mitigating the internal stress of the airbag 404 and ensuring long-term crack resistance for the floor. Furthermore, due to the placement of the support mechanism 4 and... When breaking the support tube 406, a limiting mechanism is used. The limiting mechanism is engaged with multiple circular support plates 507 and an external rubber ring 505 within the limiting ring 405, allowing multiple support mechanisms to be picked up simultaneously. This enables the simultaneous insertion and limiting of multiple support mechanisms 4, improving work efficiency. In addition, when striking the support tube 406, a limiting mechanism is installed again at the top of multiple support tubes 406, aligning the conical head 508 with the arc-shaped connection port 408. By using a hammer to strike the impact plate 504, and through the transmission of the multi-headed bent rod 501 and the crossbar 503, multiple support tubes 406 can be directly and synchronously broken, further improving construction efficiency and reducing construction difficulty.
