Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically a device for facilitating the installation of protective layer pads for pile foundation reinforcement cages. Background Technology

[0002] In the construction of bored piles, controlling the thickness of the protective layer of the reinforcing cage is a key aspect to ensure the durability and structural performance of the pile foundation. Traditional methods often use precast concrete spacers, which are manually inserted one by one into the gaps between the stirrups of the reinforcing cage and fixed with binding wire or plastic cable ties. This method has the disadvantages of low construction efficiency and difficulty in controlling installation accuracy. Since the spacers need to be inserted along the stirrups, uneven spacing, omissions, or misalignments are prone to occur during operation, resulting in deviations in the protective layer thickness exceeding the allowable range of the specifications. This affects the quality of the protective layer after the pile concrete is poured, thereby reducing the structure's corrosion resistance and load-bearing capacity.

[0003] While some improvements have been made to existing technologies, such as using plastic wheel-shaped pads or mortar pads, the problems of low installation efficiency and unstable fixing have not been fundamentally solved. In narrow construction sites or under nighttime working conditions, the installation difficulty of traditional pads is further increased, which seriously restricts the construction progress. Therefore, there is an urgent need for a device that facilitates the installation of pads for the protective layer of pile foundation reinforcement cages, so as to meet the dual requirements of efficient construction and quality control in modern pile foundation engineering. Utility Model Content

[0004] The purpose of this utility model is to provide a device that facilitates the installation of protective layer pads for pile foundation reinforcement cages, so as to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is: a device for facilitating the installation of concrete protective layer pads for pile foundation reinforcement cages, including concrete protective layer pads, wherein the inner wall of the concrete protective layer pads is provided with embedded plastic clips, the outer wall of the concrete protective layer pads is provided with a plurality of holes, and galvanized steel sheets are fixedly connected to the outer wall of the concrete protective layer pads.

[0006] Preferably, the holes are arranged in a rectangular array, and the embedded plastic clamp is adapted to the size of the concrete protective layer pad.

[0007] Preferably, the outer walls of both sides of the galvanized steel sheet are provided with arc-shaped grooves, and reflective strips are adhered to the inner walls of the arc-shaped grooves.

[0008] This utility model provides an improved device for facilitating the installation of protective layer pads for pile foundation reinforcement cages. Compared with the prior art, it has the following improvements and advantages:

[0009] This utility model incorporates an embedded plastic clamp, a concrete protective layer spacer, a galvanized steel sheet, and reflective strips. The plastic clamp of the spacer is aligned with the stirrups of the reinforcing cage. Pressing or rotating the clamp causes its opening to elastically deform, locking into the stirrups and returning to its original shape for fixation. The elastic design of the clamp prevents the spacer from easily falling off during the hoisting and lowering of the reinforcing cage. The thickness of the spacer is the designed protective layer thickness, ensuring uniform spacing between the reinforcing cage and the borehole wall. Holes in the concrete protective layer spacer allow concrete to penetrate during pouring, forming a mechanical interlock and reducing the risk of spacer detachment. A galvanized steel sheet is installed on the outer wall of the concrete protective layer spacer to improve compressive strength and corrosion resistance. Reflective strips on the outer wall of the galvanized steel sheet facilitate positioning during pile hole verticality checks, thus improving the installation efficiency of the concrete protective layer spacer for the pile foundation reinforcing cage.

[0014] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0015] This utility model provides an improved device for facilitating the installation of protective layer pads for pile foundation reinforcement cages. The technical solution of this utility model is as follows:

[0016] like Figure 1 As shown, a device for facilitating the installation of concrete protective layer spacers for pile foundation reinforcement cages includes a concrete protective layer spacer 2. The inner wall of the concrete protective layer spacer 2 is provided with an embedded plastic clamp 1, and the outer wall of the concrete protective layer spacer 2 is provided with a plurality of holes 3. A galvanized steel sheet 4 is fixedly connected to the outer wall of the concrete protective layer spacer 2. The holes 3 on the concrete protective layer spacer 2 allow concrete to seep in during pouring to form a mechanical interlock, reducing the risk of the spacer falling off. The galvanized steel sheet 4 on the outer wall of the concrete protective layer spacer 2 improves compressive strength and corrosion resistance.

[0017] Furthermore, the holes 3 are arranged in a rectangular array, and the embedded plastic clamps 1 are adapted to the size of the concrete protective layer pads 2.

[0018] Furthermore, arc-shaped grooves are provided on the outer walls of both sides of the galvanized steel sheet 4, and reflective strips 5 are adhered to the inner walls of the arc-shaped grooves.

[0019] Working principle: In the initial stage of the spacer block production, embedded plastic clamps 1 are placed in advance using the pre-made mold of the concrete protective layer spacer block. Then, the concrete is laid flat. After the concrete strength reaches the design requirements, the mold is demolded. Subsequently, the embedded plastic clamps 1 are directly clamped onto the stirrups, avoiding the need to insert the blocks one by one onto the stirrups. The mold is pre-installed with clamps. Before pouring the concrete spacer block, the embedded plastic clamps 1 are pre-fixed in specific positions within the mold, ensuring that the clamps are exposed. Concrete is poured into the mold and vibrated to compact it, so that the embedded plastic clamps 1 are integrated with the concrete. After the concrete reaches the required strength, the mold is demolded, forming a finished spacer block with pre-made clamps. During construction, the plastic clamps of the pad block are aligned with the stirrups of the reinforcing cage. By pressing or rotating, the opening of the clamp is elastically deformed, and after being inserted into the stirrup, it returns to its original shape, thus completing the fixation. The elastic design of the clamps makes the pad block less likely to fall off during the hoisting and lowering of the reinforcing cage. The thickness of the pad block is the design protective layer thickness, ensuring that the distance between the reinforcing cage and the hole wall is uniform. The holes 3 set on the concrete protective layer pad block 2 allow concrete to seep in during pouring, forming a mechanical interlock and reducing the risk of the pad block falling off. A galvanized steel sheet 4 is set on the outer wall of the concrete protective layer pad block 2 to improve compressive strength and corrosion resistance. A reflective strip 5 is set on the outer wall of the galvanized steel sheet 4 to facilitate positioning when checking the verticality of the pile hole.

[0020] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
