Description

Technical Field

[0001] This utility model belongs to the field of hydraulic engineering technology, and in particular relates to an interlocking precast concrete block assembly. Background Technology

[0002] In the fields of hydraulic engineering and coastal protection engineering, the stability and durability of slope protection structures are of paramount importance. The traditional methods of constructing slope protection structures mainly include two types: on-site concrete pouring and stone stacking.

[0003] The method of pouring concrete on site requires a series of complex procedures such as formwork construction, rebar tying, concrete mixing and pouring. It is greatly limited by factors such as weather and site conditions. The method of stacking stones makes it difficult to form a firm connection between the stones. Under the impact of water flow, the stones are prone to relative displacement, resulting in the revetment structure becoming loose and unable to be used for a long time.

[0004] In other words, the existing precast block components are mostly simple independent units, lacking reliable connection structures, which makes it easy for precast blocks to shift or fall off, making it difficult to ensure the long-term stability of the revetment structure. Utility Model Content

[0005] The purpose of this invention is to provide an interlocking precast concrete block assembly to solve the problem that existing precast block assemblies are mostly simple, independent units lacking reliable connection structures, making them prone to displacement and detachment, and thus failing to ensure the long-term stability of the revetment structure.

[0028] like Figures 1 to 3 As shown, this embodiment provides an interlocking precast concrete block assembly. This interlocking precast concrete block assembly includes a mold structure, a connecting rope 3, a positioning stake 4, a snap-fit ​​structure, and a positioning structure. The mold structure includes an upper mold 1 and a lower mold 2. The upper mold 1 is connected to the lower mold 2. The upper mold 1 and the lower mold 2 are used to cast and shape precast concrete blocks. The positioning stake 4 is connected to the lower mold 2 and is used to fix the connecting rope 3. The connecting rope 3 is connected to the positioning stake 4 and is used to connect and lift the precast concrete blocks. The snap-fit ​​structure includes a first fixing seat 5, a second fixing seat 6, a connecting column 7, and a nut 8. The first fixing seat 5 is connected to the lower mold 2, the second fixing seat 6 is connected to the upper mold 1, the connecting column 7 is inserted into the first fixing seat 5, and the nut 8 is connected to the connecting column 7. The positioning structure is connected to the lower mold 2 and is used to align the upper mold 1 and the lower mold 2. Both the upper mold 1 and the lower mold 2 have installation grooves, and the connecting rope 3 is placed in the installation grooves.

[0029] By combining the upper mold 1 and the lower mold 2, the construction process is simplified. Each individual precast concrete block is connected into a whole by the connecting rope 3, which can effectively prevent the precast blocks from shifting or falling off, ensuring the long-term stability of the revetment structure. At the same time, the connecting rope 3 facilitates the movement of the precast concrete blocks.

[0030] First, fix the lower mold 2 to prevent movement. Check that the lower mold 2 is level and ensure that the interior of both the lower mold 2 and the upper mold 1 is clean and free of debris, including residue from the previous interlocking block pouring. Then, use a sprayer to evenly apply a layer of release agent to the inner walls of the upper mold 1 and the lower mold 2. A layer of release agent also needs to be applied before installing the upper mold. Before pouring concrete, the connecting ropes 3 need to be arranged in advance. Each unit of the lower mold 2 has an installation groove in the middle for placing the connecting ropes 3. Cut the connecting ropes 3 to the designed length and manually place them in the installation groove. Each interlocking block is connected to all units by two complete connecting ropes 3. The two connecting ropes 3 are arranged in both horizontal and vertical directions. Positioning stakes 4 are set on the outer edge of the lower mold 2 to ensure that the laid connecting ropes 3 are taut. Then, the upper mold 1... Mold 1 is placed on top of lower mold 2 using a lifting device. Then, the connecting column 7 is rotated and moved into the fixed base 6. Next, the nut 8 is rotated onto the outer surface of the connecting column 7 and tightened to ensure a stable connection between upper mold 1 and lower mold 2. Concrete is then poured into the mold structure for placement. Air bubbles in the concrete are removed by a vibrating beam to prevent voids in the concrete within the mold structure. After the concrete has solidified, the nut 8 is removed, and upper mold 1 is lifted using a lifting device for demolding. The precast concrete block is simultaneously lifted by the distributed hydraulic jacks at the bottom of lower mold 2 to complete demolding and transfer it to the storage area. After demolding, a wax-based curing agent is evenly sprayed onto the surface of the precast block using a spraying device to form a sealing film for curing.

[0031] Specifically, the connecting rope 3 can be a rope made of polypropylene, with a diameter of 18 / 20mm and a tensile strength of 54kN. The rope test should comply with EN1492-4:2009 standard; the positioning stake 4 consists of a rope stake and an anchor point. The connecting rope 3 is sleeved on the outer surface of the anchor point, one end of the rope stake is connected to the side of the lower mold 2, and the anchor point is perpendicularly connected to the rope stake.

[0032] In this embodiment, multiple sets of positioning stakes 4 and snap-fit ​​structures are provided. Positioning stakes 4 and fixing base 1 5 are respectively fixedly installed on the four sides of the lower mold 2, and fixing base 2 6 is fixedly installed on the four sides of the upper mold 1.

[0033] See Figure 2 and Figure 3 In this embodiment, the positioning structure includes a push plate 9, a first spring 10, a push plate 11, and a second spring 12. The first spring 10 is connected to the lower mold 2, the push plate 9 is connected to the first spring 10, the push plate 11 is inserted on the push plate 9, and the two ends of the second spring 12 are respectively connected to the push plate 11 and the lower mold 2. The lower mold 2 has a sliding groove, and the positioning structure is inserted into the sliding groove. A sliding column 13 is fixedly installed on the lower mold 2. The push plate 9 has a positioning groove, and the sliding column 13 is placed in the positioning groove. The bottom end of the push plate 9 near the middle of the lower mold 2 has a first inclined edge, and the push plate 11 has a second inclined edge. The second inclined edge fits against the first inclined edge and slides on the first inclined edge.

[0034] By limiting the swaying of the upper mold 1 during its descent using the push plate 21, the upper mold 1 can be quickly and accurately connected to the lower mold 2, which not only saves installation time but also ensures installation accuracy.

[0035] When the upper mold 1 descends, the push plate 9 is pressed, which squeezes the first spring 10. The first spring 10 contracts elastically, and the push plate 9 descends. When the push plate 9 descends, it squeezes the push plate 11, causing the second inclined side to slide on the first inclined side. That is, the push plate 11 moves to the middle of the lower mold 2. At this time, the second spring 12 is squeezed and contracts elastically by the push plate 11. As the push plate 11 moves, it fits against the upper mold 1, preventing the upper mold 1 from shaking, and causing the upper mold 1 to descend and engage with the lower mold 2.

[0036] Specifically, the sliding column 13 is fixedly installed at the bottom of the slide groove, the first spring 10 is fixedly installed at the bottom of the slide groove, the first push plate 9 is fixedly installed at the top of the first spring 10, the second push plate 11 is slidably installed inside the first push plate 9, one end of the second spring 12 is connected to the second push plate 11, and the other end of the second spring 12 is connected to one side of the lower mold 2. The first spring 10 and the second spring 12 can be springs or other elastic elements that can reset the first push plate 9 and the second push plate 11.

[0037] In this embodiment, four sets of positioning structures are provided, which are respectively installed on the four sides of the lower mold 2.

[0038] The following is a detailed description of the application process of an interlocking precast concrete block assembly:

[0039] First, fix the lower mold 2 to prevent movement. Check that the lower mold 2 is level and ensure that the interior of both the lower mold 2 and the upper mold 1 is clean and free of debris (including residue from the previous interlocking block pouring). Then, use a sprayer to evenly apply a layer of release agent to the inner walls of the upper mold 1 and the lower mold 2. A layer of release agent also needs to be applied before installing the upper mold. Before pouring concrete, the connecting ropes 3 need to be arranged in advance. Each unit of the lower mold 2 has an installation groove in the middle for placing the connecting ropes 3. Cut the connecting ropes 3 to the designed length and manually place them into the installation groove. Each interlocking block is connected to all units by two complete connecting ropes 3, which are arranged in both horizontal and vertical directions. Positioning stakes 4 are set on the outer edge of the lower mold 2 to ensure that the laid connecting ropes 3 are taut. Then, the upper mold 1 is lifted by a lifting device, placed directly above the lower mold 2, and then lowered. As the upper mold 1 descends, it presses the push plate 9, which compresses the first spring 10. The first spring 10 elastically contracts, and the push plate 9 descends, causing it to slide on the sliding column 13. The sliding column 13 keeps the push plate 9 horizontal. As the push plate 9 descends, it presses against the push plate 11, causing the second inclined plate to slide on the first inclined plate. This means the push plate 11 moves towards the center of the lower mold 2. At this time, the second spring 12 contracts elastically under the pressure of the push plate 11. With the movement of the push plate 11, it adheres to the upper mold 1, preventing it from shaking. This allows the upper mold 1 to descend and engage with the lower mold 2. Next, the connecting column 7 is rotated and moved into the fixed base 6. Then, the nut 8 is rotated onto the outer surface of the connecting column 7 and tightened to ensure the upper mold... The connection between mold 1 and lower mold 2 is stable. Then, concrete is poured into the mold structure for placement. Then, the air bubbles in the concrete are removed by the vibrating beam to avoid voids in the concrete within the mold structure. After the concrete solidifies, nut 8 is removed, and upper mold 1 is lifted by a lifting device for demolding. The precast concrete block is simultaneously lifted by the distributed hydraulic jacks at the bottom of lower mold 2 to complete demolding and transfer to the storage area. After demolding, a wax-based curing agent is evenly sprayed onto the surface of the precast block using a spraying device to form a sealing film for curing.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
