Description

Technical Field

[0001] This utility model belongs to the field of building construction, specifically relating to a rebar-free structure for the construction of inter-pile mesh in cast-in-place piles. Background Technology

[0002] Cast-in-place piles are a common foundation treatment technology widely used in various construction projects, primarily suitable for scenarios requiring deep foundations or special geological conditions. The spacing between adjacent cast-in-place piles is generally around 200mm. Soil loss between piles can easily lead to ground settlement, thus requiring grouting reinforcement for protection. The traditional construction method involves excavating the earthwork after the cast-in-place piles are installed, with each layer of excavated earth followed by a layer of inter-pile mesh installation. The main difficulty in inter-pile mesh installation lies in the placement of the transverse reinforcing bars. Traditional construction requires rebar installation, but with a typical pile spacing of only about 200mm, it's difficult to clean the pile holes and install rebar within this 200mm working area, making it challenging to guarantee the quality of the rebar installation. Utility Model Content

[0003] To address the aforementioned issues, this utility model discloses a rebar-free structure for constructing the inter-pile mesh of cast-in-place piles. During the fabrication of the rebar cage for the cast-in-place piles, the positions of the transverse rebars are pre-positioned, and steel sleeves are pre-embedded at the positioning points. After the concrete is poured, the transverse rebars are connected. The structure is simple and easy to implement, reduces the lap length of the rebars, and also ensures the construction quality of the inter-pile soil.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] The construction of the inter-pile mesh for cast-in-place piles is a non-rebar-installation structure. Steel sleeves are pre-embedded horizontally in the reinforcing cage of the cast-in-place pile. The steel sleeves are hollow inside, with both ends extending out of the reinforcing cage. Horizontal reinforcing bars are inserted horizontally into the steel sleeves. The horizontal reinforcing bars and the steel sleeves are connected by binding wire. A reinforcing mesh is set between the horizontal reinforcing bars, and a concrete surface layer is sprayed on the surface of the reinforcing mesh.

[0006] As an improvement of this utility model, 3-6 steel sleeves are pre-embedded horizontally on each steel cage.

[0007] As an improvement of this utility model, the steel cage is provided with vertical reinforcement bars for fixing and connecting steel sleeves.

[0008] As an improvement of this utility model, the transverse reinforcing bars are made of Φ12 steel bars.

[0009] The beneficial effects of this utility model are as follows:

[0010] The present invention describes a rebar-free structure for the construction of inter-pile mesh in cast-in-place piles. It is pre-embedded, simple in structure, and easy to operate. It reduces the lap length of the rebar while ensuring the construction quality of the inter-pile soil. Attached Figure Description

[0016] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0017] As shown in the figure, the non-rebar-installation structure for the inter-pile mesh construction of the cast-in-place pile of this utility model has a steel sleeve 2 pre-embedded horizontally in the steel cage 1 of the cast-in-place pile. The steel sleeve 2 is hollow inside, and both ends of the steel sleeve 2 extend out of the steel cage 1. The horizontal steel bars 3 are inserted horizontally into the steel sleeve 2. The horizontal steel bars 3 and the steel sleeve 2 are connected by binding with iron wire. A steel mesh 4 is provided between adjacent horizontal steel bars 3, and a concrete surface layer 5 is sprayed on the surface of the steel mesh 4.

[0018] When constructing the steel cage for the retaining piles, the positions of the transverse steel bars 3 are determined in advance, and steel sleeves 2 are pre-embedded at the positioning points. 3-6 steel sleeves are pre-embedded transversely on each steel cage, and the two ends of the steel sleeves 2 are sealed with tape. To ensure that the steel sleeves 2 do not deviate during the pouring process of the retaining piles, vertical reinforcement bars 6 are installed inside the piles and welded and tied to the steel sleeves 2.

[0019] After the retaining piles are poured, the steel sleeve 2 embedded in the concrete is removed and the tape is removed during the cleaning of the soil between the piles. After the internal steel mesh 4 is laid, the transverse steel bar 3 is inserted into the steel sleeve 2 to make the transverse steel bar 3 pass through. The transverse steel bar is Φ12 steel bar. Finally, the concrete surface layer 5 is sprayed on the surface of the steel mesh 4. This construction process is pre-embedded, has a simple structure, is easy to operate, reduces the lap length of the steel bars, and also ensures the construction quality of the soil between the piles.

[0020] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
