Description

Technical Field

[0001] This utility model relates to a suspended paving base structure for imitating ancient Beijing bricks. Background Technology

[0002] Traditional antique-style Beijing bricks (such as gold bricks and square bricks) are usually laid using the mortar bedding method or dry laying method, which has the following technical defects:

[0003] High foundation treatment costs

[0004] The entire ground needs to be hardened, and a concrete subbase (usually ≥100mm thick) needs to be poured. The construction period is long and the material consumption is large.

[0005] Soft soil and collapsible foundations require additional reinforcement, further increasing costs.

[0006] Poor drainage and moisture-proof performance

[0007] The bottom of the brick is in direct contact with the ground, and capillary water absorption can easily lead to efflorescence and frost heave (especially serious in northern regions);

[0008] Traditional grouting drainage is inefficient, and rainwater tends to accumulate after seepage, accelerating the weathering of the bricks.

[0009] Insufficient structural stability

[0010] The mortar layer is prone to hollowing and cracking due to foundation settlement, which can lead to brick fracture (Beijing bricks are brittle and have low flexural strength).

[0011] Lacking elastic cushioning, it has a high damage rate when stepped on by pedestrians or impacted by heavy objects.

[0012] Maintenance difficulties

[0013] If a single brick is damaged, the entire brick needs to be pried up, which can easily damage surrounding bricks during repair.

[0014] The level cannot be adjusted, and the entire structure needs to be reworked after settling.

[0015] Based on the above problems, we designed a suspended paving base structure for antique Beijing bricks that adopts an elevated installation, reduces the cost of ground hardening, and is easy to maintain. Utility Model Content

[0016] The technical problem to be solved by this utility model is to provide a suspended paving base structure for antique Beijing bricks that adopts an overhead installation, reduces the cost of ground hardening, and is easy to maintain.

[0017] To solve the above problems, the present invention adopts the following technical solution:

[0018] A suspended paving base structure imitating ancient Beijing bricks includes,

[0019] The base frame consists of multiple parallel base frame poles suspended above the ground. The spacing between adjacent base frame poles is equal, and the upper surfaces of all the base frame poles are on the same horizontal plane.

[0020] The carrier plate is mounted between adjacent base frame rods, and a sealing plate is installed between adjacent carrier plates in the Y direction, and adjacent carrier plates in the X direction are pressed against each other;

[0021] A shock-absorbing pad is laid on top of the carrier plate, and a drainage gap is formed between adjacent shock-absorbing pads. Antique Beijing bricks are laid on the shock-absorbing pad.

[0022] Preferably, the bottom of the base frame rod is symmetrically provided with two L-shaped support plates, and an assembly groove is machined on the horizontal surface of the support plate. A leveling component is assembled through the assembly groove. The upper end of the base frame rod is bent to form a U-shaped drainage groove, and water flowing in through the drainage gap is collected into the drainage groove. The bottom ends of the carrier plate are cast with retaining strips, which are inserted into the drainage groove. The two ends of the sealing sheet extend above the drainage groove.

[0023] Preferably, threaded holes are provided on both sides of the carrier plate, and the threaded holes on both sides are staggered. A tightening screw is screwed into the threaded hole to maintain a distance between two adjacent carrier plates in the X direction, and the carrier plates are tightened with the adjacent carrier plate by unscrewing the tightening screw.

[0024] Preferably, a vertically penetrating weight-reducing groove is machined on the surface of the carrier plate, and an insert strip that fits the weight-reducing groove is injection molded at the bottom of the shock-absorbing pad, with the insert strip and the weight-reducing groove having an interference fit.

[0025] Preferably, the leveling component includes a casting rod and a threaded rod, the threaded rod being threadedly engaged with the casting rod, the lower end of the casting rod being inserted into the ground and cast and fixed; a tray is provided on the body of the threaded rod, the tray being located at the bottom of the support plate, and the upper end of the threaded rod passing through the assembly groove and being threadedly engaged with a clamping plate.

[0026] Preferably, the threaded rod is clearance-fitted with the assembly groove.

[0027] Preferably, a first drainage groove is provided through the upper part of the shock-absorbing pad in the X direction.

[0028] Preferably, an arc-shaped, upward-convex reinforcing plate is welded between the two support plates.

[0029] The beneficial effects of this utility model are:

[0030] The suspended paving base structure provided by this utility model has the following significant advantages compared with traditional processes:

[0031] 1. Reduce construction costs and foundation requirements

[0032] Only localized hardening is required (11 points on the support plate), reducing concrete usage by more than 70%.

[0033] It is suitable for non-hardened surfaces (such as rammed earth, lawn, and gravel base), expanding the scenarios for ancient building restoration.

[0034] 2. Highly efficient drainage and moisture-proof

[0035] The elevated floor design creates an air circulation channel and effectively isolates ground moisture;

[0036] Dual drainage system:

[0037] Water seepage from brick joints → centralized drainage through drainage channels;

[0038] Water from brick cracks → first drainage channel → discharged horizontally to avoid siltation.

[0039] 3. Improve structural durability

[0040] Shock absorption and protection: The shock absorption pad can absorb more than 80% of the impact energy (actual measurement shows that the breakage rate of Beijing bricks is reduced by 90%);

[0041] Dynamic leveling: The threaded rod, in conjunction with the casting rod, enables elevation adjustment to adapt to uneven settlement;

[0042] Anti-displacement design: The clamping strip and the tightening screw form a double limit to ensure that the horizontal displacement of the carrier plate is ≤0.5mm.

[0043] 4. Convenient maintenance and environmental friendliness

[0044] The modular design allows for the replacement of individual bricks (without damaging the surrounding structure);

[0045] Recyclable components account for ≥85% (base frame poles, carrier plates, etc. can be disassembled and reused);

[0046] The drainage channel can be connected to a water collection system to achieve rainwater recycling.

[0047] 5. Compatibility and scalability

[0048] It is compatible with a variety of traditional floor tiles (gold bricks, bluestone slabs, terracotta bricks, etc.), and only the thickness of the shock-absorbing pad needs to be adjusted. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0061] See Figure 1 and Figure 2 The suspended paving base structure shown includes,

[0062] The base frame rods 1 are arranged in parallel, with multiple rods 1 suspended above the ground. The spacing between adjacent base frame rods 1 is equal, and the upper surfaces of the multiple base frame rods 1 are on the same horizontal plane.

[0063] Carrier plate 2, the carrier plate 2 is mounted between adjacent base frame rods 1, a sealing plate 21 is installed between adjacent carrier plates 2 in the Y direction, and adjacent carrier plates 2 in the X direction are pressed against each other;

[0064] Shock-absorbing pad 3 is laid on top of the carrier plate 2, and a drainage gap is formed between adjacent shock-absorbing pads 3. Antique Beijing bricks are laid on the shock-absorbing pad 3.

[0065] In the above technical solution, only local hardening of the ground is required to meet the installation requirements of the base frame pole 1.

[0066] The cost of ground pretreatment has been significantly reduced.

[0067] Secondly, the design of the elevated base pole 1 is adopted. After the antique-style Beijing bricks are laid, an elevated layer is created between the bottom of the bricks and the ground, which helps to remove moisture.

[0068] The design of the shock-absorbing pad 3 can absorb the impact when stepping on the Beijing bricks, greatly reducing the chance of the bricks breaking.

[0069] Compared to ground paving, this product can provide stable and flat support at the bottom of the bricks.

[0070] The base frame rod 1 should be made of 304 stainless steel, and the shock-absorbing pad 3 should be made of EPDM rubber with a hardness of 60±5 Shore A.

[0071] See Figure 1 and Figure 3As shown, two L-shaped support plates 11 are symmetrically arranged at the bottom of the base frame rod 1. An assembly groove 12 is machined on the horizontal surface of the support plate 11, and a leveling component 13 is assembled through the assembly groove 12. The upper end of the base frame rod 1 is bent to form a U-shaped drainage groove 14, and water flowing in through the drainage gap is collected into the drainage groove 14. The bottom ends of the carrier plate 2 are cast with retaining strips 221, which are inserted into the drainage groove 14. The two ends of the sealing plate 21 extend above the drainage groove 14.

[0072] In the above technical solution, the combination of foot plate 11 and leveling component 13 can achieve the horizontal adjustment of the base frame rod 1, so as to provide a flat installation condition for the brick.

[0073] The drainage channel 14, formed by bending the base frame rod 1, allows water falling from the gaps in the brickwork to drain away during rainy days, facilitating the recycling of this water and preventing ground subsidence caused by rainwater erosion.

[0074] In the above technical solution, the design of the clip 221 is adopted. By cooperating with the drainage groove 14, the X-direction displacement of the carrier plate 2 is restricted.

[0075] A sealing sheet 21 is provided in the Y direction of the carrier plate 2 so that a seal can be formed between adjacent carrier plates 2 in the Y direction, allowing water on the surface of the carrier plate 2 to drain into the drainage groove 14.

[0076] See Figure 2 and Figure 3 As shown, threaded holes 22 are provided on both sides of the carrier plate 2. The threaded holes 22 on both sides are staggered. A tightening screw 23 is screwed into the threaded hole 22 to maintain a distance between two adjacent carrier plates 2 in the X direction, and the tightening screw 23 is screwed out to tighten with the adjacent carrier plate 2.

[0077] In the above technical solution, considering the fit error between the drainage groove 14 and the clip 221, the carrier plate 2 has a gap due to X-direction displacement.

[0078] We designed the aforementioned tightening screw 23. During the assembly process, by pushing out the tightening screw 23, a fixed distance can be maintained between adjacent carrier plates 2 in the X direction, preventing the carrier plates 2 from shifting.

[0079] See Figure 3 , Figure 4 and Figure 5 As shown, a vertically penetrating weight-reducing groove 24 is processed on the surface of the carrier plate 2, and an insert strip 31 that fits the weight-reducing groove 24 is injection molded at the bottom of the shock-absorbing pad 3. The insert strip 31 is interference-fitted with the weight-reducing groove 24.

[0080] The design of the weight reduction groove 24 can reduce the overall weight of the carrier plate 2 by 10-20%.

[0081] Secondly, the weight reduction groove 24 can also cooperate with the embedded strip 31 so that the shock absorption pad 3 is fixed relative to the carrier plate 2 after installation.

[0082] See Figure 1 and Figure 6 As shown, the leveling component 13 includes a casting rod 131 and a threaded rod 141. The threaded rod 141 is threadedly engaged with the casting rod 131. The lower end of the casting rod 131 is inserted into the ground and cast in place. A tray 151 is provided on the body of the threaded rod 141. The tray 151 is located at the bottom of the support plate 11. The upper end of the threaded rod 141 passes through the assembly groove 12 and is threadedly engaged with a clamping plate 161.

[0083] In the above technical solution, the installation position of the pouring rod 131 is predetermined on the ground, then a hole is drilled, the pouring rod 131 is inserted vertically, and then concrete is filled in for pouring and fixing.

[0084] Next, install the threaded rod 141. Adjust the screw depth of the threaded rod 141 as needed to support the base rod 1 horizontally and adjust it to the required height. Then, complete the clamping by rotating the clamping plate 161 downwards.

[0085] The threaded rod 141 is clearance-fitted with the assembly groove 12.

[0086] The advantage of clearance fit is that it provides the threaded rod 141 with room for fine-tuning, making assembly easier.

[0087] See Figure 2 As shown, a first drainage groove 331 is provided through the upper part of the shock-absorbing pad 3 in the X direction.

[0088] Considering the cracks generated during the sintering process of the antique-style Beijing bricks, which may lead to some water seepage, we designed the first drainage groove 331 mentioned above to improve the drainage of the bottom of the Beijing bricks.

[0089] See Figure 1 As shown, an arc-shaped, upward-convex reinforcing plate 199 is welded between the two support plates 11.

[0090] The design of the reinforcing plate 199 can increase the structural strength and stability of the base frame rod 1. Depending on the needs, it can be selected whether the arc top of the reinforcing plate 199 contacts the inner bottom surface of the base frame rod 1. In this embodiment, it is non-contact.
