Detailed Implementation

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example 1: As shown in the figure, the present invention provides a lightweight and high-strength precast post-cast strip sealing plate, which includes a first original reinforced concrete structure exterior wall 1 and a second original reinforced concrete structure exterior wall 2. A continuous post-cast strip 3 is provided between the first original reinforced concrete structure exterior wall 1 and the second original reinforced concrete structure exterior wall 2, and structural steel bars 8 are provided in the post-cast strip 3.

[0019] Multiple precast post-pouring strip sealing plates are laid at post-pouring strip 3. The precast post-pouring strip sealing plates are connected end to end. The precast post-pouring strip sealing plates are reinforced concrete structures. The precast post-pouring strip sealing plates include an outer hanging plate 4. A hanging bar is installed inside the outer hanging plate 4. The upper end of the hanging bar extends out of the outer hanging plate 4. The upper end of the hanging bar is a U-shaped hook 9.

[0020] The outer panel 4 is a cuboid. Two connecting blocks 5 are set at the lower part of the outer panel 4 near both ends. Structural steel bars 8 are set in the post-pouring strip 3. Two U-shaped fixing bars 10 are set at intervals on the outer panel 4. The two U-shaped fixing bars 10 are located inside the two sides of the post-pouring strip and extend out of the outer panel 4. The two U-shaped fixing bars 10 are fixedly connected to the structural steel bars 8 in the post-pouring strip 3.

[0021] The first original reinforced concrete exterior wall 1 has a first groove 6 corresponding to the connecting block 5, and the second original reinforced concrete exterior wall 2 has a second groove 7 corresponding to the connecting block 5. The first groove 6 is set along the entire length, and the second groove 7 is set along the entire length. The lengths of the first groove 6 and the second groove 7 are equal to those of the post-cast strip 3. The two connecting blocks 5 are respectively inserted into the first groove 6 and the second groove 7. The two ends of the precast post-cast strip sealing plate are respectively inserted into the first original reinforced concrete exterior wall 1 and the second original reinforced concrete exterior wall 2 through the two connecting blocks 5.

[0022] The outer mounting plate 4 is 1800 mm long, 600 mm wide, and 100 mm thick. The two connecting blocks 5 have a long side of 600 mm, a width of 200 mm, and a thickness of 100 mm. The long side of the connecting blocks 5 is parallel to the wide side of the outer mounting plate 4.

[0023] Example 2: Construction steps of this utility model: Step 1: The project team conducted an in-depth study on the issue of early closure of the post-pouring strip 3 in the basement. Taking into account the actual situation of the project, such as structural characteristics, construction period requirements, and site conditions, the team determined to adopt a construction plan of sealing the post-pouring strip with lightweight, high-strength precast slabs.

[0024] Step Two: Based on site requirements and specifications, conduct a detailed design for the precast post-cast strip sealing plate, determine its dimensions, and at the same time, draw detailed construction drawings, including detailed drawings, plan views, side views, and elevation views of the precast post-cast strip sealing plate, to ensure accurate basis during construction.

[0025] Step 3: Select a flat and hardened area close to the post-cast strip 3 as the precast site. If the site is not flat, it needs to be treated first, such as leveling and compacting, to ensure that the site is solid and stable and facilitates subsequent construction operations. Lay a layer of plastic sheeting on the surface of the precast site to prevent the precast post-cast strip sealing concrete from sticking to the site when demolding, which would affect the quality and appearance of the precast post-cast strip sealing plate.

[0026] Step 4: According to the design reinforcement requirements, select scrap steel bars for processing. Steel bar processing includes straightening, cutting, bending and other processes. Strictly follow the design dimensions and shape to ensure that the length, angle and spacing of the steel bar hooks meet the specifications and design requirements. Design a mold, including the outer hanging plate 4 and two connecting blocks 5 near the two ends below the outer hanging plate 4. Set the steel bars in the mold and accurately pre-embed the lifting bars in the steel bar skeleton. The upper end of the lifting bar extends out of the outer hanging plate 4 to form an inverted U-shaped lifting hook 9. Set two U-shaped fixing bars 10 at intervals on the outer hanging plate 4 to ensure that the precast post-cast strip sealing plate will not fall off or be damaged during the hoisting process.

[0027] Step 5: Concrete pouring. Prioritize the use of leftover concrete after each pour and the concrete used for pump washing in the pump pipe to reduce material waste. Before pouring, the concrete raw materials should be inspected to ensure that the concrete mix proportions are accurate and that the concrete slump, workability, and other properties meet the construction requirements. Mark the slab thickness control lines in the mold in advance to accurately control the thickness of the precast post-pouring strip during the pouring process. Use an immersion vibrator to compact the concrete, ensuring that there are no voids, honeycombs, pitting, or other defects inside the concrete. After the concrete is poured, it should be cured in a timely manner.

[0028] Step Six: After transporting multiple precast post-cast strip sealing plates to the construction site of post-cast strip 3 in the basement, use No. 10 iron wire to tie two U-shaped fixing bars 10 to the structural steel bars 8 inside post-cast strip 3 to ensure that the precast post-cast strip sealing plates are installed accurately, firmly and stably, and tightly connected to the surrounding structure. At the same time, insert the two connecting blocks of the precast post-cast strip sealing plates into the first groove 6 and the second groove 7 opened on the first original reinforced concrete structure exterior wall 1 and the second original reinforced concrete structure exterior wall 2, respectively, to play a limiting role. The post-cast strip 3 is sealed with precast post-cast strip sealing plates. After installation, the gaps between the precast post-cast strip sealing plates should be treated, such as by sealing with cement mortar, to prevent rainwater, groundwater and other water from seeping into the post-cast strip 3.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
