Abstract
Description
Technical Field
[0001] This application relates to the field of earth-filled garage roof technology, specifically to an earth-filled structure with a hollow bottom for garage roofs. Background Technology
[0002] Garage roof slabs are typically constructed to support the rooftop green planting layer, and must balance load-bearing and drainage requirements. During design and construction, the garage roof slab is built first, followed by landscaping (steps such as covering the garage roof slab with soil, constructing drainage facilities, and planting plants).
[0003] During landscape design and construction, to meet the needs of plant root growth, some designs may involve higher mounds in certain areas to allow for sufficient downward root growth. However, higher mounds can increase the load on the garage roof slab, sometimes exceeding its designed load-bearing capacity. In such cases, modifications to the landscape design and construction plan are necessary, such as lowering the height of the mounds. However, lowering the mound height can result in insufficient downward root growth, necessitating changes in plant varieties and the surrounding landscape design and construction. These design and construction modifications are substantial, making adjustments to the mound height quite inconvenient.
[0004] Therefore, it is necessary to develop a structure that can flexibly adjust the local height of the earth mound to meet the growth needs of plant roots, while avoiding exceeding the load-bearing limit of the garage roof slab, thus improving the greening effect and the adaptability of the earth mound structure. Utility Model Content
[0005] To address the problem of inconvenience in adjusting the height of local earth mounds in existing technologies, this utility model provides a hollow earth mound structure for garage roof slabs.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] This utility model provides a hollow-bottom shaped earth-laying structure for a garage roof, which is set on the main body of the roof slab, and a planting soil layer is laid on top of the main body of the roof slab. Its features are:
[0008] The top of the main body of the roof slab is provided with a waterproof layer. A brick wall is provided above the waterproof layer of the main body of the roof slab. A water storage tank is provided inside the brick wall. A cover plate is provided on the top of the brick wall. A seepage hole connected to the water storage tank is provided on the cover plate.
[0009] Drainage blind pipes are installed in the planting soil layer, and a guide pipe is installed at the bottom of the drainage blind pipe, which is then inserted through the cover plate.
[0010] It also includes a locking mechanism, which is disposed on the cover plate.
[0011] Preferably, the locking mechanism includes a mounting base, a pin, an arc-shaped plate, a fixing base, and a locking plate. Multiple sets of mounting bases are fixedly arranged at intervals on both sides of the cover plate. Each mounting base has a through hole penetrating the cover plate. The pin is rotatably disposed within the through hole. The arc-shaped plate is located below the cover plate and fixedly mounted on the pin. The fixing base is fixedly mounted on the brickwork enclosure and aligned with the mounting base. The fixing base has a countersunk hole, and a locking plate that matches the arc-shaped plate is fixedly disposed on the inner wall of the countersunk hole. When the cover plate is placed on top of the brickwork enclosure, the mounting base on the cover plate is aligned with the fixing base on the brickwork enclosure, so that... When the cover plate is lowered, the pin on the mounting base is inserted into the countersunk hole on the fixing base, thereby limiting the horizontal position of the cover plate and ensuring its stability. After placement, the arc-shaped plate on the pin is located below the clamping plate. Rotating the pin on the mounting base causes the bottom arc-shaped plate to rotate, thereby rotating the arc-shaped plate to overlap with the clamping plate in the vertical direction. At this point, the cover plate is vertically limited, ensuring the connection stability between the cover plate and the brickwork enclosure. When it is necessary to disassemble the cover plate, simply rotate the pin to cancel the overlap between the arc-shaped plate and the clamping plate. The operation is convenient.
[0012] Preferably, the brickwork enclosure is fixedly provided with support bars inside the water storage tank. The top of the support bars is flush with the top of the brickwork enclosure. After the cover plate is placed on the brickwork enclosure, the support bars can provide auxiliary support for the middle of the cover plate, thereby improving the stability of the cover plate.
[0013] Preferably, the support bars are arranged in multiple sets at intervals within the water storage tank. These multiple sets of spaced support bars provide auxiliary support to different positions of the cover plate, further improving the stability of the cover plate.
[0014] Preferably, the bottom of the support bar is provided with a through hole. The support bar installed inside the water storage tank divides the water storage tank, and the through hole at the bottom of the support bar can connect the divided spaces to ensure normal water storage operation in the water storage tank.
[0015] Preferably, the bottom of the cover plate is fixedly provided with reinforcing ribs, and the brickwork enclosure and support strip are provided with slots that match the reinforcing ribs. The reinforcing ribs at the bottom of the cover plate improve the strength of the cover plate, and when the cover plate is placed on the brickwork enclosure, the mounting base and the fixing base can be quickly aligned by aligning the reinforcing ribs with the slots, thereby improving the splicing speed.
[0016] Preferably, the cross-sectional width of the brick enclosure is W, and the total height of the brick enclosure and the cover plate is H, where W = 240mm and 400 ≤ H ≤ 1000mm. Setting the cross-sectional width of the brick enclosure to 240mm ensures the strength of the brick enclosure, and by limiting the range of the total height of the brick enclosure and the cover plate, the brick enclosure and the cover plate can be selected at different construction heights to meet different planting needs.
[0017] Preferably, the side wall of the brick enclosure is equipped with a drainage pipe, and the distance between the inlet end of the drainage pipe and the cover plate is H1, where H > H1 ≥ 0.5H. When the rainwater stored in the water storage tank exceeds the height of the drainage pipe, the excess rainwater will be discharged through the drainage pipe to ensure that the water storage tank can carry out normal water storage operations.
[0018] The advantages of adopting the above technical solution are:
[0019] This utility model includes a brick enclosure and a cover plate. By setting the brick enclosure and cover plate in the planting area on the top of the main body of the roof slab, the height of the soil mound in the local planting area can be adjusted to meet the soil thickness requirements for planting. The brick enclosure and cover plate can also further improve the load-bearing capacity of the main body of the roof slab in the planting area. The water storage tank of the brick enclosure can retain rainwater that seeps in from the planting soil and the seepage holes to meet the growth needs of the plants. Attached Figure Description

[0026] The technical solutions of 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. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] like Figure 1-4 As shown in the figure, this utility model embodiment discloses a garage roof slab with a hollow bottom and a shaped earth-filled structure. It is set on the roof slab body 1, and a planting soil layer 100 is laid on the top of the roof slab body 1. A waterproof layer is set on the top of the roof slab body 1. A brick enclosure 2 is set on the roof slab body 1 above the waterproof layer. A water storage tank 201 is set inside the brick enclosure 2. A cover plate 3 is set on the top of the brick enclosure 2. A seepage hole connected to the water storage tank 201 is set on the cover plate 3. A drainage blind pipe 101 is set inside the planting soil layer 100. A conduit 102 is set at the bottom of the drainage blind pipe 101. The conduit 102 passes through the cover plate 3. It also includes a locking mechanism, which is set on the cover plate 3.
[0028] In at least one embodiment, the locking mechanism includes a mounting base 5, a pin 501, an arc-shaped plate 502, a fixing base 6, and a locking plate 602. Multiple sets of mounting bases 5 are fixedly arranged at intervals on both sides of the cover plate 3. Each mounting base 5 has a through hole penetrating the cover plate 3. The pin 501 is rotatably disposed within the through hole. The arc-shaped plate 502 is located below the cover plate 3 and fixedly mounted on the pin 501. The fixing base 6 is fixedly mounted on the brickwork enclosure 2 and aligned with the mounting base 5. The fixing base 6 has a countersunk hole 601, and a locking plate 602, which mates with the arc-shaped plate 502, is fixedly disposed on the inner wall of the countersunk hole 601. When the cover plate 3 is placed on top of the brickwork enclosure 2, the mounting base 5 on the cover plate 3 is aligned with the fixing base 6 on the brickwork enclosure 2, so that... When the cover plate 3 is lowered, the pin 501 on the mounting base 5 is inserted into the countersunk hole 601 on the fixing base 6 to limit the cover plate 3 in the horizontal direction and ensure the stability of the cover plate 3. After placement, the arc plate 502 on the pin 501 is located below the clamping plate 602. Rotating the pin 501 on the mounting base 5 causes the bottom arc plate 502 to rotate, thereby rotating the arc plate 502 to overlap with the clamping plate 602 in the vertical direction. At this time, the cover plate 3 is limited in the vertical direction, ensuring the connection stability between the cover plate 3 and the brick wall 2. When it is necessary to disassemble the cover plate 3, simply rotate the pin 501 to cancel the overlap between the arc plate 502 and the clamping plate 602. The operation is convenient.
[0029] In at least one embodiment, a support bar 4 is fixedly installed in the water storage tank 201 within the brick wall enclosure 2. The top of the support bar 4 is flush with the top of the brick wall enclosure 2. After the cover plate 3 is placed on the brick wall enclosure 2, the support bar 4 can provide auxiliary support for the middle part of the cover plate 3, thereby improving the stability of the cover plate 3.
[0030] In at least one embodiment, the support bars 4 are arranged in multiple sets at intervals within the water storage tank 201. The multiple sets of spaced support bars 4 provide auxiliary support to different positions of the cover plate 3, further improving the stability of the cover plate 3.
[0031] In at least one embodiment, the bottom of the support bar 4 is provided with a through hole 401. The support bar 4 provided in the water storage tank 201 divides the water storage tank 201. The through hole 401 at the bottom of the support bar 4 can connect the divided spaces to ensure normal water storage operation in the water storage tank 201.
[0032] In at least one embodiment, a reinforcing rib 301 is fixedly provided at the bottom of the cover plate 3, and a slot 202 that matches the reinforcing rib 301 is provided on the brickwork enclosure 2 and the support strip 4. The reinforcing rib 301 at the bottom of the cover plate 3 improves the strength of the cover plate 3, and when the cover plate 3 is placed on the brickwork enclosure 2, the mounting base 5 and the fixing base 6 can be quickly aligned by aligning the reinforcing rib 301 with the slot 202, thereby improving the splicing speed.
[0033] In at least one embodiment, the cross-sectional width of the brick enclosure 2 is W, and the total height of the brick enclosure 2 and the cover plate 3 is H, where W = 240 mm and 400 ≤ H ≤ 1000 mm. Setting the cross-sectional width of the brick enclosure 2 to 240 mm ensures the strength of the brick enclosure 2. Furthermore, by limiting the range of the total height of the brick enclosure 2 and the cover plate 3, the brick enclosure 2 and the cover plate 3 can be selected at different construction heights to meet different planting needs.
[0034] In at least one embodiment, a drain pipe 203 is installed on the side wall of the brick enclosure 2. The distance between the inlet end of the drain pipe 203 and the cover plate 3 is H1, where H > H1 ≥ 0.5H. When the rainwater stored in the water storage tank 201 exceeds the height of the drain pipe 203, the excess rainwater will be discharged through the drain pipe 203 to ensure that the water storage tank 201 can carry out normal water storage operations.
[0035] When constructing the roof slab of the garage, workers first lay a waterproof layer on top of the roof slab. Then, according to the planting area plan, they set up brick enclosures 2 in the corresponding areas of the planting area to form a water storage tank 201. Next, a cover plate 3 is placed on top of the brick enclosures 2 to seal the opening at the top of the water storage tank 201. After the cover plate 3 is sealed, a planting soil layer 100 is applied to the top of the roof slab and the cover plate 3. Once the planting soil layer 100 is applied, greening can begin in the corresponding planting area. The brick enclosures 2 and the cover plate 3 below the planting area increase the... The height of the mound in the planting area is increased, enhancing the load-bearing capacity of the main body 1 and ensuring the required soil thickness. The top of the cover plate 3 has seepage holes, allowing rainwater seeping into the planting soil layer 100 to enter the water storage tank 201 for storage. Rainwater from other areas of the planting soil layer 100 is collected and discharged through the drainage blind pipe 101. Rainwater can also flow into the water storage tank 201 through the conduit 102 at the bottom of the drainage blind pipe 101, increasing the water storage capacity of the water storage tank 201. Workers can adjust the height of the brick enclosure 2 according to the growth needs of the plants in the planting area, ensuring the adjusted mound height meets the plant growth requirements. Furthermore, the locking mechanism on the cover plate 3 connects and limits the connection between the cover plate 3 and the brick enclosure 2, ensuring their stability.
[0036] In addition, some of the drainage holes on the cover plate 3 are equipped with absorbent cotton strips. The bottom of the absorbent cotton strips is located at the bottom of the water storage tank 201. The absorbent cotton strips can transport the rainwater stored in the water storage tank 201 to the planting soil layer 100 above the cover plate 3 to ensure the normal growth of the plants.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
