Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a basement exterior wall post-cast strip enclosing structure and a construction method thereof. Background Art

[0002] When backfilling the earth, the traditional post-cast strip of the basement outer wall uses brickwork on the outside of the basement outer wall to carry out water and soil retaining sealing treatment.

[0003] The masonry strength of these basement vertical post-cast joints is insufficient, often leading to damage to the masonry walls by backfill machinery and multiple repairs. Furthermore, traditional brick masonry walls must be painted before waterproofing. Summary of the Invention

[0004] In order to overcome the defects of the existing technology, a basement outer wall post-cast strip closed structure and a construction method thereof are now provided to solve the problem that the closed brickwork of the post-cast strip of the existing basement outer wall is easily damaged by backfill machinery.

[0005] To achieve the above purpose, a basement exterior wall post-cast strip enclosed structure is provided, comprising:

[0006] An arched steel frame plate is arranged on the outside of the basement outer wall, with the inner side of the steel frame plate facing the post-cast strip of the basement outer wall. Two opposite sides of the steel frame plate extend back to form overlapping flanges, and the two overlapping flanges are respectively overlapped with the basement outer wall on opposite sides of the post-cast strip;

[0007] Concrete cover is poured on the outside of the steel frame plate and covers the lap flange.

[0008] Furthermore, a steel skeleton is embedded in the concrete protective layer, and the position of the steel skeleton corresponds to the position of the lap flange.

[0009] Furthermore, the overlap width between the lap flange and the basement exterior wall is greater than 170 mm.

[0010] Furthermore, the steel plate is coated with an anti-rust coating.

[0011] Furthermore, the lap flanges are connected to a row of reinforcing bars, and a row of reinforcing bars is embedded in the exterior wall of the basement.

[0012] Furthermore, a row of reinforcing bars is arranged along the vertical direction.

[0013] Furthermore, a row of reinforcing bars is connected to the steel structure of the basement exterior wall.

[0014] The present invention provides a construction method for a basement exterior wall post-cast strip closed structure, comprising the following steps:

[0015] A steel frame plate is installed on the outer side of the basement outer wall so that the inner side of the steel frame plate faces the post-cast zone of the basement outer wall;

[0016] Overlap the lap flanges on opposite sides of the steel frame plate to the basement exterior walls on opposite sides of the post-cast strip;

[0017] A concrete cover is poured on the outside of the steel frame plate, and the concrete cover wraps around the lap flange.

[0018] Furthermore, when the overlapping flanges on opposite sides of the steel frame plate are overlapped on the basement outer walls on opposite sides of the post-cast strip, a row of reinforcing bars on the overlapping flanges are connected to the steel structure of the basement outer wall. When pouring the concrete of the basement outer wall, a row of reinforcing bars are buried in the concrete of the basement outer wall.

[0019] The beneficial effect of the present invention is that the basement exterior wall post-cast strip closing structure of the present invention is sealed by pre-buried steel frame plates during the pouring process of the basement exterior wall, and a construction process for temporary protection is performed during the construction process. Through precise production and installation of steel frame plates, the basement exterior wall post-cast strip is completely covered, and the overlapping flanges of the steel frame plates are tightly fitted to the walls on both sides of the post-cast strip, protecting the wall from pollution and influence of debris such as water and mud, thereby ensuring safety and quality requirements during the construction process.

[0020] The steel frame plate of the basement outer wall post-cast zone closed structure is welded and fixed to the outer wall steel bars, thereby preventing the steel frame plate from being deformed due to earth impact during backfilling.

[0021] The basement exterior wall post-cast strip enclosed structure of the present invention features a protective layer of concrete poured outside the steel frame plates, which is covered by the plates and internally provided with structural reinforcement to prevent rust on the plates. This enhances the structural strength of the enclosed structure and protects it from damage by backfill machinery during backfilling. The basement exterior wall post-cast strip enclosed with steel frame plates is suitable for various basement exterior wall post-cast strips, providing overall stability and reliability, and providing long-term protection for the post-cast strip wall.

[0022] The present invention's post-cast strip enclosed structure for basement exterior walls offers a relatively short construction period, improving construction efficiency, saving time and labor costs, and effectively ensuring project progress, significantly increasing construction efficiency. Furthermore, the steel frame plates offer a long service life, providing extended protection for the post-cast strip wall and reducing subsequent maintenance work. BRIEF DESCRIPTION OF THE DRAWINGS

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] Reference Figure 1 and Figure 2 As shown, the present invention provides a basement exterior wall post-cast strip enclosed structure, comprising a steel frame plate 1 and a concrete protective layer 2.

[0033] In this embodiment, a vertical post-cast strip 30 is formed on the basement outer wall 3 .

[0034] The steel frame plate 1 is arched or curved. It is installed on the outside of the basement exterior wall 3. The inside of the steel frame plate 1 faces the post-cast strip 30 of the basement exterior wall 3. Lapping flanges 11 extend from opposite sides of the steel frame plate 1. The two lap flanges 11 overlap the basement exterior wall 3 on opposite sides of the post-cast strip 30.

[0035] The concrete cover 2 is poured on the outer side of the steel frame plate 1 and covers the lap flange 11 .

[0036] In this embodiment, see Figure 2 As shown, the steel frame plate 1 is formed by bending 3mm thick patterned steel plate. The center portion of the patterned steel frame plate 1 is bent multiple times along the length of the patterned steel plate to form an arch. The opposite sides of the patterned steel plate in the width direction are bent to form overlapping flanges 11. The overlapping width of the overlapping flange 11 with the basement exterior wall 3 is greater than 170mm.

[0037] The steel frame plate 1 is laid on the outside of the post-cast strip 30. The steel bars of the post-cast strip 30 are welded to the inside of the steel frame plate 1. The steel frame plate 1 is overlapped to the basement outer wall 3 through the overlap flange 11, with an overlap length of not less than 20mm and full welding on both sides.

[0038] As a preferred embodiment, the steel bone plate 1 is coated with an anti-rust coating.

[0039] Anti-rust paint is applied to the steel plate 1 to protect the steel plate 1 from the influence of the external environment, increase the corrosion resistance of the steel plate 1, and thus extend the service life of the steel plate 1

[0040] The overlapping flange 11 is connected to a row of reinforcing bars 12. A row of reinforcing bars 12 is embedded in the outer wall 3 of the basement.

[0041] In this embodiment, a row of reinforcing ribs 12 is arranged along the vertical direction.

[0042] As a preferred embodiment, a row of reinforcing bars 12 is connected to the steel structure 31 of the basement outer wall 3 .

[0043] In order to prevent the steel frame plate 1 from being deformed due to the impact of soil during backfilling, reinforcement bars 12 with a diameter of 10 mm and an interval of 200 mm are used. Two reinforcement bars 12 are arranged at equal intervals in the longitudinal direction and are welded to the steel structure 31 of the basement outer wall 3 by plug welding.

[0044] A steel reinforcement skeleton 21 is embedded within the concrete cover 2. The position of the steel reinforcement skeleton 21 corresponds to the position of the lap flange 11. The steel reinforcement skeleton 21 serves as structural reinforcement. The concrete cover 2 and the basement exterior wall 3 are poured simultaneously.

[0045] The present invention provides a construction method for a closed structure of a post-cast strip 30 of a basement outer wall 3, comprising the following steps:

[0046] S1. Install a steel frame plate 1 on the outer side of the basement outer wall 3 so that the inner side of the steel frame plate 1 faces the post-cast strip 30 of the basement outer wall 3.

[0047] S2. Overlap the overlapping flanges 11 on the opposite sides of the steel frame plate 1 to the basement outer walls 3 on the opposite sides of the post-cast strip 30 respectively.

[0048] When the lap flanges 11 on opposite sides of the steel frame plate 1 are respectively overlapped on the basement outer walls 3 on opposite sides of the post-cast strip 30, a row of reinforcing bars 12 on the lap flanges 11 are connected to the steel structure 31 of the basement outer wall 3. When the concrete of the basement outer wall 3 is poured, the row of reinforcing bars 12 are buried in the concrete of the basement outer wall 3.

[0049] S3. Cast a concrete protective layer 2 on the outer side of the steel frame plate 1 , and the concrete protective layer 2 covers the lap flange 11 .

[0050] The basement exterior wall post-cast strip closing structure of the present invention provides a basement exterior wall post-cast strip closing construction process using a steel frame plate, which can be used for basement exterior wall post-cast strip construction.

[0051] The basement exterior wall post-cast strip closing structure of the present invention is a construction process for temporary protection during the construction process by sealing with pre-buried steel frame plates after the basement exterior wall is poured. Through precise steel frame plate production and installation, the basement exterior wall post-cast strip is completely covered, and the overlapping flanges of the steel frame plates are tightly fitted to the walls on both sides of the post-cast strip, protecting the wall from pollution and influence of debris such as water and mud, thereby ensuring safety and quality requirements during the construction process.

[0052] The steel frame plate of the basement outer wall post-cast zone closed structure is welded and fixed to the outer wall steel bars, thereby preventing the steel frame plate from being deformed due to earth impact during backfilling.

[0053] The basement exterior wall post-cast strip enclosure structure of the present invention features a 110mm thick concrete protective layer cast outside the steel frame plate, which is covered with internal structural reinforcement to prevent rust and enhance the structural strength of the enclosure. The basement exterior wall post-cast strip enclosure structure employs steel frame plates and is suitable for various basement exterior wall post-cast strips. The overall structure is stable and reliable, providing long-term protection for the post-cast strip wall.

[0054] The present invention's post-cast strip enclosed structure for basement exterior walls offers a relatively short construction period, improving construction efficiency, saving time and labor costs, and effectively ensuring project progress, significantly increasing construction efficiency. Furthermore, the steel frame plates offer a long service life, providing extended protection for the post-cast strip wall and reducing subsequent maintenance work.
