Description

Sheet for fixing heating pipes and floor structure comprising the same The present application claims the benefit of the filing date of Korean Patent Application No. 10-2024-0149462 filed with the Korean Intellectual Property Office on October 29, 2024, the entire contents of which are incorporated herein. The present invention relates to a sheet for fixing heating pipes and a floor structure including the same. A conventional structure for a layered floor structure to reduce inter-floor noise caused by floor impact sound in multi-unit housing such as apartments is shown in Fig. 1 below. More specifically, after pouring a concrete slab, a cushioning material (20) is installed, and after pouring lightweight foamed concrete (30), a finishing mortar (40) pouring process is performed. Before pouring the finishing mortar (40), a heating pipe (50) is installed on the cushioning material (20), then the finishing mortar (40) is poured, and finally, the floor is finished with a floor finishing material (not shown in the drawing). Meanwhile, recently, in order to reduce impact sound by increasing the surface density of the upper structure of the cushioning material, a layered structure of the interlayer floor is applied in which the lightweight foamed concrete (30) is excluded and replaced with a finishing mortar (40), as shown in Fig. 2 below. Here, in order to satisfy the thermal insulation performance (thermal transmittance) standard due to the exclusion of the lightweight foamed concrete (30), the thickness of the cushioning material (20) is partially increased, and the remaining increase in thickness is applied to the increase in the thickness of the finishing mortar (40) to prevent cracking of the finishing mortar (40) due to the exclusion of the lightweight foamed concrete (30). As such, the thickness of the finishing mortar (40) increases due to structural changes in the floor between floors to reduce impact sound. Accordingly, if the heating pipe (50) is installed on the upper surface of the cushioning material (20) as before and the finishing mortar (40) is poured, there is a problem that the time for the floor surface temperature to rise during heating increases by twofold due to the increased depth of the pipe. Therefore, before pouring the finishing mortar (40), it is necessary to fix the heating pipe (50) at a predetermined height away from the cushioning material (20) and then proceed with the pouring of the finishing mortar (40). Korean Registered Utility Model No. 20-0407901 discloses an inverted U-shaped synthetic resin fixing clip for hot water heating pipes; however, as mentioned above, in inter-floor structures where the thickness of the finishing mortar is increased, problems arise due to the increased pipe depth. Figures 1 and 2 are schematic diagrams showing the stacked structure of the interlayer floor, respectively. FIG. 3 is a schematic diagram showing a sheet for fixing heating pipes according to one embodiment of the present invention. FIG. 4 is a schematic diagram showing a sheet for fixing heating pipes according to one embodiment of the present invention. FIG. 5 is a schematic diagram showing a sheet for fixing heating pipes according to one embodiment of the present invention. FIG. 6 is a schematic diagram showing a pin for fixing a heating pipe according to one embodiment of the present invention. The present invention will be described in more detail below. In the present invention, when it is said that a certain member is located "on" another member, this includes not only the case where a certain member is in contact with another member, but also the case where another member exists between the two members. In the present invention, when a part is described as "comprising" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Conventional floor structures are manufactured by applying lightweight foamed concrete over floor cushioning material, fixing heating pipes on top of it, and then applying finishing mortar. Since this structure requires two steps of mortar application—such as lightweight foamed concrete and finishing mortar—it is costly and time-consuming. Furthermore, there is a problem in that the finishing mortar, which is the upper structure, is lightweight, resulting in almost no impact sound reduction effect. Recently, as inter-floor noise has become a social issue, there is a need to develop sound-dampening materials for construction to improve floor impact sound. In other words, to solve the aforementioned problems, it is necessary to increase the weight of the finishing mortar to reduce floor impact sound. Accordingly, lightweight foamed concrete is excluded, and a solid mortar structure that finishes with only one application of mortar is preferred. In order to maintain the efficiency of floor heating, the heating pipes must be spaced approximately 24 mm apart from the
