Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite precast panel technology, and in particular to a composite precast panel for water tanks with a concrete-lined HDPE anchor plate. Background Technology
[0002] The concrete-lined HDPE anchor plate for water tanks is a precast component used in water tank construction. It combines the structural strength of concrete with the corrosion resistance of high-density polyethylene. This type of composite precast plate is commonly used to build water tanks, water containers, sewage treatment facilities, and other structures that require long-term water storage or treatment.
[0003] Existing precast concrete-lined HDPE anchored composite panels for water tanks achieve ultra-low energy consumption for wall insulation by combining vacuum insulation boards and graphene insulation boards, utilizing the insulation properties of both. Furthermore, pre-drilled anchor holes on any sidewall of the graphene insulation board along its thickness reduce the opening area of the wall coating, ensuring a stable overall connection. However, if the professional adhesive between the vacuum insulation board and the graphene insulation board is unevenly applied or not fully cured, or if the interface between the graphene insulation board and the concrete / DPE board fails to form an effective bond, interlayer slippage or delamination may occur between the insulation layer and the main structure under load. At this point, the precast slab cannot form a coordinated load-bearing system of "concrete layer + HDPE board + insulation layer". During bending, each layer cannot bear the bending moment synchronously, and during shear, the interlayer shear force cannot be transferred, which reduces the bending, shear and tensile properties of the precast slab and weakens the overall load-bearing capacity of the structure.
[0004] Therefore, it is necessary to provide a new type of composite precast slab for water tanks with a concrete-lined HDPE anchor plate to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a composite precast slab for water tanks with a concrete-lined HDPE anchor plate.
[0006] The present invention provides a composite precast slab for water tanks with a concrete lining and an HDPE anchor plate, comprising an anchor plate reinforced concrete layer and an HDPE anchor plate. An interface bonding reinforcement layer is connected to one end of the anchor plate reinforced concrete layer adjacent to the HDPE anchor plate, and the HDPE anchor plate is connected to the end of the interface bonding reinforcement layer away from the anchor plate reinforced concrete layer.
[0007] Preferably, the inner walls of the through holes opened on both sides of the reinforced concrete layer of the anchoring wall panel are provided with special pre-embedded connectors for the wall panel, and the inner walls of the several grooves opened on the surface of the reinforced concrete layer of the anchoring wall panel are all fixedly connected with pre-embedded threaded sleeves for loading and unloading, and the inner walls of the grooves opened at both ends of the reinforced concrete layer of the anchoring wall panel are all equipped with pre-embedded threaded sleeves for hoisting.
[0008] Preferably, the HDPE anchoring wall panel is an HDPE board, and the surface of the HDPE board is provided with HDPE anchoring wall panel anchoring claws.
[0009] Preferably, the anchoring claw is embedded in the reinforced concrete layer of the anchoring wall plate.
[0010] Preferably, the HDPE board is made of high-density polyethylene material.
[0011] Preferably, the special connectors embedded in the wall panel are made of metal.
[0012] Compared with related technologies, the composite precast slab for water tanks with a concrete-lined HDPE anchor plate provided by this utility model has the following beneficial effects:
[0013] This utility model provides a composite precast slab for water tanks with a concrete-lined HDPE anchor plate. First, a precast slab mold is made. Then, the HDPE anchor plate is placed into the mold according to the design position, with the anchor claws facing the concrete pouring direction. Special pre-embedded connectors for the wall panel are fixed, and pre-embedded threaded sleeves are hoisted and removed. Before pouring, an interface bonding reinforcement layer is added to the surface of the HDPE board. Then, concrete is prepared and poured. A vibration process is used to ensure the concrete is dense and fully bonded to the HDPE anchor plate and all pre-embedded components. The precast slab is cured after pouring and demolded after reaching the specified strength. This device, due to the presence of the reinforcement layer, allows the HDPE board and concrete to form a tighter bond, enabling them to work together better under stress, improving the precast slab's bending, shear, and tensile strength, thereby enhancing the overall load-bearing capacity of the structure.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Please refer to the following: Figure 1 , Figure 2 , Figure 3 as well as Figure 4 ,in, Figure 1 A structural schematic diagram of a precast composite slab for water tanks with a concrete-lined HDPE anchor plate provided by this utility model. Figure 2 for Figure 1 A structural schematic diagram from another perspective is shown; Figure 3 for Figure 1 The diagram shows the structure of the HDPE anchored wall panel. Figure 4 for Figure 1 The diagram shows the structure of the reinforced concrete layer and the interface bonding reinforcement layer of the anchoring wall panel.
[0021] In the specific implementation process, such as Figures 1 to 4 As shown, one end of the anchored wall panel reinforced concrete layer 1 adjacent to the HDPE anchored wall panel 2 is connected to an interface bonding reinforcement layer 3. The HDPE anchored wall panel 2 is connected to the end of the interface bonding reinforcement layer 3 away from the anchored wall panel reinforced concrete layer 1. The inner walls of the through holes opened on both sides of the anchored wall panel reinforced concrete layer 1 are provided with wall panel pre-embedded special connectors 5. The wall panel pre-embedded special connectors 5 are made of metal. The inner walls of several grooves opened on the surface of the anchored wall panel reinforced concrete layer 1 are all fixedly connected with loading and unloading pre-embedded threaded sleeves 6, and the inner walls of the grooves opened at both ends of the anchored wall panel reinforced concrete layer 1 are all hoisted with pre-embedded threaded sleeves 7.
[0022] It should be noted that the HDPE anchor wall panel 2 is an HDPE board 8. The surface of the HDPE board 8 is provided with HDPE anchor wall panel 2 anchor claws 9. The anchor claws 9 are embedded in the reinforced concrete layer 1 of the anchor wall panel. The HDPE board 8 is made of high-density polyethylene material. High-density polyethylene material is a highly crystalline, non-polar thermoplastic resin polymerized from ethylene monomers. It has a series of excellent physical and chemical properties, which makes it widely used in many fields.
[0023] Furthermore, the interface bonding reinforcement layer 3 is a key transitional component connecting the reinforced concrete layer 1 of the anchor wall panel and the HDPE anchor wall panel. Its core function is to enhance the interfacial bonding performance of the two different materials (concrete and HDPE). Concrete and HDPE boards have poor affinity, and the mechanical interlocking of the anchor claws 9 alone may result in local gaps. The interface bonding reinforcement layer 3 forms a chemical bond with the cement hydration products in the concrete through its own polar groups, and at the same time, it physically adsorbs onto the surface of the HDPE board, constructing a "chemical + physical" dual bond to eliminate weak points at the interface.
[0024] The manufacturing process of the composite precast panel is as follows: First, a precast panel mold is made. Then, the HDPE anchor wall panel 2 is placed into the mold according to the design position, with the anchor claw 9 facing the concrete pouring direction. The wall panel pre-embedded special connector 5, the pre-embedded threaded sleeve 7 is hoisted, and the pre-embedded threaded sleeve 6 is loaded and unloaded. Before pouring, an interface bonding reinforcement layer 3 is added to the surface of the HDPE panel 8. Then, concrete is prepared and poured. The vibration process is used to make the concrete dense and fully bonded with the HDPE anchor wall panel 2 and each pre-embedded component. The precast panel is cured after pouring and demolded after reaching the specified strength.
[0025] HDPE (high-density polyethylene) is a highly crystalline, non-polar thermoplastic resin produced by the polymerization reaction of ethylene monomers. HDPE has a high density, a linear molecular structure with few branches, and high crystallinity, thus possessing high hardness, rigidity, and mechanical strength. Its tensile strength can reach 20~30MPa, and it has strong impact resistance and is not easily broken.
[0026] The working principle of this utility model is as follows: In use, firstly, a precast slab mold is made, then the HDPE anchor wall panel 2 is placed into the mold according to the design position, so that the anchor claw 9 faces the concrete pouring direction, and the wall panel pre-embedded special connector 5, the hoisting pre-embedded threaded sleeve 7, and the loading and unloading pre-embedded threaded sleeve 6 are fixed. Before pouring, an interface bonding reinforcement layer 3 is added to the surface of the HDPE board 8, then concrete is prepared and poured. The vibration process is used to make the concrete dense and fully bonded with the HDPE anchor wall panel 2 and each pre-embedded component. The precast slab after pouring is cured and demolded after reaching the specified strength.
[0027] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.
[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
