[0002] A formwork-free cast-in-place concrete pool is a type of cast-in-place concrete pool structure constructed using a formwork-free process. Its core feature is that it eliminates the traditional formwork support process and replaces the formwork function with other methods (such as precast components, special processes or materials) to directly pour concrete on-site to form the pool.

[0003] However, in the construction of traditional concrete pools, the formwork process is cumbersome and consumes a lot of time and materials. It requires multiple procedures such as on-site formwork erection, rebar tying and formwork removal. Not only is the construction cycle long, but after the formwork is removed, problems such as poor surface flatness and grout leakage at the joints often occur, affecting the quality and aesthetics of the pool. Therefore, a formwork-free cast-in-place concrete pool structure is proposed to solve the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 An embodiment of this utility model is provided: a formwork-free cast-in-place concrete pool structure, including a formwork 1, a wedge-shaped groove 2 is provided on one side of the formwork 1, and a wedge block 3 is fixedly connected to the other side of the formwork 1. By inserting the wedge block 3 into the wedge-shaped groove 2, the whole can be horizontally spliced ​​together. A positioning component 4 is provided on the surface of the top of the formwork 1.

[0019] Reference Figure 2 and Figure 3 The positioning component 4 includes a positioning block 41. The bottom end of the mold body 1 has an installation groove that fits the positioning block 41. By splicing the positioning block 41 with the installation groove at the bottom end, the two sets of mold bodies 1 can be spliced ​​vertically. The positioning block 41 is fixedly connected to the upper surface of the mold body 1. The inner side wall of the positioning block 41 is elastically connected to the limiting block 43 through a return spring 42. One end of the return spring 42 is fixedly connected to the outer wall of the limiting block 43, and the other end of the return spring 42 is fixedly connected to the inner wall of the positioning block 41. The limiting block 43 is slidably connected to the inner wall of the positioning block 41. The outer wall at the bottom end of the limiting block 43 is fixedly connected to a pressing block 44. The function of the return spring 42 is to automatically reset the position after the pressing block 44 presses the limiting block 43 and moves. The pressing block 44 passes through and is slidably connected to the inner wall of the mold body 1. The side wall of the installation groove at the bottom end of the mold body 1 has a slot. The locking between the limiting block 43 and the slot can quickly fix the position of the two sets of mold bodies 1 after splicing.

[0020] Reference Figure 1 and Figure 2The bottom end of the mold body 1 is provided with a groove 6. The inner side wall of the groove 6 is detachably equipped with a protrusion 5. The protrusion 5 and the groove 6 are inserted with damping. The bottom end of the protrusion 5 is fixedly connected with a reinforcing block 7. The bottom end of the reinforcing block 7 is provided with a cavity, and the inner side of the cavity is provided with multiple sets of serrations. By providing serrations on both sides of the cavity of the reinforcing block 7 and providing through holes on both sides, the contact between the whole and the concrete can be increased by the reinforcing block 7 when laying the base layer, thereby increasing the overall installation stability.

[0021] Reference Figure 1 and Figure 4 The mold body 1 also includes a main body layer 11. The main body layer 11 is made of expandable polystyrene particles through a gradient foaming process to form a closed-cell structure. A fireproof layer 12 is fixedly connected to the bottom of the main body layer 11. The fireproof layer 12 is made of inorganic fireproof material.

[0022] Working principle: The module 1 serves as the basic unit. The wedge-shaped groove 2 on one side and the wedge block 3 fixed on the other side form a horizontal splicing structure. When it is necessary to expand the size of the pool, the wedge block 3 of one module 1 is inserted into the wedge-shaped groove 2 of the adjacent module 1. By utilizing the fitting relationship between the wedge block 3 and the wedge-shaped groove 2, multiple modules 1 can be tightly spliced ​​in the horizontal direction, and the horizontal frame of the pool can be quickly constructed.

[0023] Positioning component 4 is responsible for positioning and fixing the upper and lower parts of the mold 1. The positioning block 41 fixed on the upper surface of the mold 1 fits into the mounting groove at the bottom of the other mold 1, forming a preliminary upper and lower positioning. The positioning block 41 is connected to the limiting block 43 through the return spring 42. The push block 44 fixed at the bottom of the limiting block 43 penetrates the inner wall of the mold 1. When assembling the upper and lower parts, the positioning block 41 of the upper mold 1 is first aligned with the mounting groove of the lower mold 1 and inserted. At this time, the push block 44 is pressed, and the push block 44 drives the limiting block 43 to slide against the elastic force of the return spring 42 on the inner wall of the positioning block 41. When the upper mold 1 descends to the appropriate position, the slot on the side wall of the mounting groove of the lower mold 1 is aligned with the limiting block 43. The push block 44 is released, and the elastic action of the return spring 42 causes the limiting block 43 to spring into the slot, realizing the rapid fixing of the upper and lower mold 1 and ensuring the structural stability of the pool in the vertical direction.

[0024] The groove 6 at the bottom of the mold 1 and the protrusion 5 are connected by a damping insertion. The reinforcing block 7 fixed at the bottom of the protrusion 5 plays a key role. The bottom of the reinforcing block 7 has a cavity with multiple sets of serrations. When the base layer is laid, the concrete will fill the cavity of the reinforcing block 7 and tightly interlock with the serrations. At the same time, the concrete will further enhance the connection strength through the through holes on both sides of the reinforcing block 7. This design greatly increases the contact area and friction between the mold 1 and the concrete base layer, effectively improving the installation stability of the entire pool structure, making it less prone to displacement or loosening when subjected to concrete pouring pressure and subsequent use loads.

[0025] The main body layer 11 of the mold 1 is made of expandable polystyrene particles through a gradient foaming process to form a closed-cell structure. This structure gives the mold 1 good thermal insulation performance and can effectively reduce the heat exchange between the inside and outside of the pool. The fireproof layer 12 fixed at the bottom of the main body layer 11 is made of inorganic fireproof material. In the event of a fire or other emergency, the fireproof layer 12 can effectively block the spread of flames and ensure the safety of the pool structure. At the same time, it can also resist the damage of high temperature to the mold 1 during the concrete pouring process, ensuring construction safety and the integrity of the pool structure.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
