Description

Technology Field

[0001] The present invention relates to a precast concrete modular swimming pool. Background Technology

[0003] Conventional methods for manufacturing residential swimming pools involve extensive plumbing work, and numerous problems arise due to inadequate foundation work. Since the construction required for a swimming pool includes structural framing, waterproofing, finishing, electrical work, plumbing, and filtration—all necessary regardless of scale—it is impossible to manufacture a pool without skilled technicians. Consequently, precast structures, which involve manufacturing the equipment in advance, transporting it, and then installing it, are being installed. However, conventional precast structures are limited to facilities of fixed sizes due to restrictions on transport size and weight, making it necessary to develop technologies to improve this situation. The problem to be solved

[0012] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. However, it should be noted that the following embodiments are provided to aid in understanding the present invention and that the scope of the present invention is not limited to the following embodiments. The following embodiments are provided to more completely explain the present invention to those with average knowledge in the relevant technical field, and detailed descriptions of known configurations that are judged to unnecessarily obscure the technical essence of the present invention will be omitted.

[0013] FIG. 1 is a schematic perspective view of a precast concrete module swimming pool according to one embodiment of the present invention.

[0014] Figure 2 is a schematic diagram showing a disassembled part of the precast concrete module swimming pool shown in Figure 1.

[0015] Referring to FIGS. 1 and 2, a precast concrete module swimming pool according to one embodiment of the present invention may include side blocks (1000) forming both sides of the swimming pool, middle blocks (2000) connecting the side blocks (1000) arranged on both sides to each other, a joint beam (3000) connecting the side blocks (1000) and the middle blocks (2000); and a cover (4000) covering the upper part of the joint beam (3000). Additionally, the joint beam (3000) may be bolted together with the middle blocks (2000) and the side blocks (1000).

[0016] Here, if the size of the precast concrete module swimming pool is increased, the number of middle blocks (2000) can be increased and placed between the side blocks (1000).

[0017] In addition, the combination of the side block (1000) and the middle block (2000) of the present invention may be subjected to a post-tensioning method.

[0018] FIG. 1a is a drawing showing the combination of a side block (1000) and a middle block (2000) according to one embodiment of the present invention.

[0019] Referring to FIG. 1a, two side blocks (1000) and a middle block (2000) may be connected to each other to form a tension hole (H4). When the tension hole (H4) is connected from the side block (1000) to the middle block (2000), it may form a single passage. Additionally, the tension hole (H4) may be formed in a shape that penetrates to the left and right sides in the drawing. Furthermore, three or more tension holes (H4) may be formed in the side block (1000) and the middle block (2000). A steel wire (W) may be inserted into such a tension hole (H4). Here, the steel wire (W) has an ultimate strength of 1860 MPa or more and may be formed of a material such as KSD 7002 SWPC7BL. Before or after such a tension wire (W) is inserted, a sealing material may be applied to the joint surface of the side block (1000) and the middle block (2000) to waterproof the joint surface. Next, after concrete is poured, the tension hole (H4) into which the tension wire (W) is inserted may be tensioned using a hydraulic device to apply a compressive force to the side block (1000) and the middle block (2000). Accordingly, the side block (1000) and the middle block (2000) come into close contact with each other due to the compressive force, thereby forming structural stability.

[0020] Each configuration will be explained in detail below with reference to the drawings.
