Description

Technical Field

[0001] This utility model relates to the field of post-pouring strip protection technology, and in particular to an assembled post-pouring strip protection device. Background Technology

[0002] Post-cast strips, as a key technical measure in modern construction engineering to control concrete shrinkage, temperature stress, and uneven settlement, are widely used in basements, ultra-long structures, and the connection between high-rise buildings and podiums. Their core function is to release early stress through temporarily left structural gaps, which are then sealed and poured after the main structure has stabilized, thereby reducing the risk of cracking and improving overall integrity. However, during the long period of several weeks or even months that post-cast strips are left in place, protective devices are needed to cover the gaps to prevent debris intrusion, rainwater leakage, and construction errors. This places high demands on the sealing, stability, and adaptability of the protective structure. Currently, post-cast strip protection commonly uses traditional methods such as wooden formwork, steel plates, or precast concrete slabs. The design concept remains a customized "one strip, one slab" model, requiring custom-made boards based on the actual width of the post-cast strip. This results in poor versatility, and the protective boards are difficult to reuse after use, increasing construction costs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a prefabricated post-pouring strip protection device, which solves the problem of poor versatility and difficulty in reusing the protective plates for post-pouring strips, leading to increased construction costs.

[0004] According to an embodiment of the present invention, an assembled post-pouring strip protection device includes a protective plate and an extension plate. There are several protective plates, and at least one opposite side of each protective plate is provided with a connecting groove. A connecting block is provided between two adjacent protective plates. The two ends of the connecting block are respectively locked in the connecting grooves of the two protective plates. The bottom of each protective plate is also provided with a locking member to fix the connecting block to the protective plate. One end of the extension plate is provided with a protrusion, and the other end of the extension plate is provided with a slope. The protrusion of each extension plate is adapted to the connecting groove.

[0005] Compared with existing technologies, this utility model has the following advantages: By prefabricating multiple protective plates in the factory and setting connecting grooves between the protective plates, the stability of the connection between the protective plates is improved by locking the connecting blocks into the connecting grooves between adjacent protective plates and using locking devices to detachably connect the adjacent protective plates. This prevents the two protective plates from separating during use. The protrusions of the extension plate also match the connecting grooves, allowing the extension plate to be installed on the outermost side of the protective plate. The slope on the extension plate facilitates the transport vehicle to pass over the protective plate. This ensures that the protective plate provides stable protection without requiring the transport vehicle to bypass the post-pouring strip, saving time. Through the detachable connection of multiple protective plates, only protective plates of uniform specifications need to be prefabricated in the factory. Subsequently, the appropriate number of protective plates can be assembled according to the length and width of the post-pouring strip. This provides strong versatility and facilitates reuse, reducing construction costs.

[0006] Furthermore, it also includes several limiting blocks, each of which is detachably installed at the bottom of the protective plate.

[0007] Furthermore, the locking component is a connecting bolt, and the bottom of the protective plate has a screw hole for the connecting bolt to pass through, and the connecting block also has an insertion hole for one end of the connecting bolt to pass through.

[0008] Furthermore, it also includes a connecting plate, which also has through holes for connecting bolts to pass through.

[0009] Furthermore, each connecting block is covered with a water-stop strip.

[0010] Furthermore, each extension plate has a mounting groove at its top, and a warning banner is embedded in the mounting groove.

[0011] Furthermore, each extension plate is provided with countersunk holes, and anchor bolts are installed in the countersunk holes. Attached Figure Description

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 and Figure 2 As shown in the figure, this utility model embodiment proposes an assembled post-pouring strip protection device, including a protective plate 1 and an extension plate 4. There are several protective plates 1. At least one opposite side of each protective plate 1 is provided with a connecting groove. A connecting block 2 is provided between two adjacent protective plates 1. The two ends of the connecting block 2 are respectively locked in the connecting groove of the two protective plates 1. The bottom of each protective plate 1 is also provided with a locking member 3 to fix the connecting block 2 to the protective plate 1. One end of the extension plate 4 is provided with a protrusion 5, and the other end of the extension plate 4 is provided with a slope. The protrusion 5 of each extension plate 4 is adapted to the connecting groove. In this embodiment, the four side walls of the protective plate 1 are provided with connecting grooves to facilitate the placement of the protective plate 1 in the width and length directions of the post-cast strip. When installing the protective plate 1 to protect the post-cast strip, an appropriate number of protective plates 1 are selected according to the width or length of the post-cast strip. In this embodiment, two protective plates 1 are provided in the width direction of the post-cast strip, and the two protective plates 1 are respectively mounted on both sides of the post-cast strip. A connecting block 2 is provided at the adjacent position of the two protective plates 1, and the two ends of the connecting block 2 are respectively locked in the connecting groove of the two protective plates 1, thereby improving the stability of the connection between the two protective plates 1. Then, the connecting block 2 located in the connecting groove is locked and fixed to the protective plate 1 by the locking member 3, so that the connection between the two protective plates 1 is stable and will not detach in the opposite direction. After the protective plates 1 are connected, the extension plate 4 is attached. One end with the protrusion 5 is inserted into the connecting groove of the outermost protective plate 1, which allows some transport vehicles to pass over the top of the protective plate 1, shortening the transportation distance. Multiple protective plates 1 are arranged sequentially along the length of the post-cast strip, and connecting plates 7 are also set between the connecting grooves of adjacent protective plates 1, so that multiple protective plates 1 are connected into a whole. Through the detachable connection of multiple connecting plates 7, workers can select the appropriate number of protective plates 1 to assemble according to different widths and lengths of post-cast strips. Each protective plate 1 has the same structure, and the protrusion 5 of the extension plate 4 is also adapted to the connecting groove, which facilitates manufacturing at the factory. In subsequent use, adjacent protective plates 1 are connected by connecting plates 7 and locking parts 3, which can also adapt to post-cast strips of different widths and lengths. It has strong versatility, is easy to reuse, and significantly saves costs.

[0018] like Figure 2As shown, furthermore, it also includes limiting blocks 6, of which there are several, each of which is detachably mounted on the bottom of the protective plate 1. In this embodiment, the limiting blocks 6 have wing plates at both ends, and the limiting blocks 6 are detachably connected to the bottom of the protective plate 1 by bolts. Each protective plate 1 has a limiting block 6 at its bottom, and one side of the limiting block 6 is in close contact with the side wall of the post-pouring strip. By connecting the limiting blocks 6 to the protective plate 1, the limiting blocks 6 restrict the movement of the protective plate 1 in the width direction of the post-pouring strip, especially when a transport vehicle passes over the protective plate 1, further restricting the slippage of the protective plate 1. It should be noted that most post-pouring strips contain a reinforcing steel skeleton, and the size of the limiting blocks 6 can be manufactured according to the distance between the protective plate 1 and the reinforcing steel skeleton.

[0019] like Figure 2 As shown, the locking element 3 is a connecting bolt. The bottom of the protective plate 1 has a screw hole for the connecting bolt to pass through, and the connecting block 2 also has an insertion hole for one end of the connecting bolt to pass through. Specifically, the screw hole can be pre-drilled or opened when connecting the protective plate 1 and the connecting block 2. One end of the connecting bolt is screwed into the screw hole, ultimately allowing the end of the connecting bolt to be inserted into the insertion hole of the connecting block 2, thereby restricting the movement of the connecting plate 7 within the connecting groove. By connecting the connecting block 2 to both protective plates 1 respectively via connecting bolts, the two protective plates 1 are prevented from detaching during use.

[0020] like Figure 2 and Figure 3 As shown, it further includes a connecting plate 7, which also has through holes for connecting bolts to pass through. In this embodiment, the connecting plate 7 is located at the bottom of the protective plate 1 and at the junction of the two protective plates 1. When the connecting bolts are screwed into the protective plate 1, they first pass through the connecting plate 7. The two connecting bolts fix the connecting plate 7 to the bottom of the protective plate 1. The connecting plate 7 connects the two protective plates 1 to improve the connection strength, and also disperses the force when the top of the protective plate 1 is subjected to the pressure of the transport vehicle passing by.

[0021] like Figure 2 and Figure 3 As shown, furthermore, each connecting block 2 is covered with a water-stop strip 8. Specifically, the water-stop strip 8 is a water-swellable water-stop strip 8. Due to the water-swellable water-stop strip 8's property of swelling when exposed to water, when it rains, some rainwater seeps in from between the two protective plates 1 and comes into contact with the water-swellable water-stop strip 8. After encountering water, the water-swellable water-stop strip 8 expands and deforms 2-3 times, filling the gap between the two protective plates 1 and the connecting block 2, thus preventing leakage.

[0022] like Figure 1 and Figure 3As shown, each extension plate 4 has a mounting groove at its top, and a warning banner 9 is embedded in the mounting groove. Specifically, the warning banner 9 can be composed of LED lights or coated with fluorescent agent, so as to indicate at night that the area is a post-pouring strip, thereby serving as a warning, enhancing the safety of the construction site, and reducing the risk of accidents.

[0023] like Figure 1 and Figure 3 As shown, each extension plate 4 is further provided with a countersunk hole, and an anchor bolt 10 is installed in the countersunk hole. The extension plate 4 is fixed to the building structure on both sides of the post-cast strip by the anchor bolt, which restricts the movement of the extension plate 4 and the protective plate 1 and improves the stability of the device. Preferably, the bottom of the extension plate 4 is provided with a water-absorbing sponge, which can be embedded in the unevenness of the ground to prevent rainwater from overflowing into the post-cast strip from the connection between the extension plate 4 and the building.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
