Description

Flooring Material Assembly for Flooring Construction to Reduce Inter-Floor Noise The present invention relates to a construction material assembly for constructing a floor that reduces inter-floor noise, and more specifically, to providing an assembly of floor construction materials that minimizes the generation of inter-floor noise and simultaneously facilitates the installation of heating pipes when constructing an indoor floor surface of a multi-unit dwelling. In most multi-unit dwellings such as apartments, inter-floor noise inevitably becomes a major source of complaints, and in response to these requests, construction companies have recently been making various attempts to resolve the issues of inter-floor noise and sound transmission between floors. A widely adopted, inexpensive yet efficient means of resolving inter-floor noise is to install sound-absorbing materials made of high-density elastic material in the form of pads on the floor slab surface before pouring mortar on the floor construction surface. This method is widely used as it is known to have a substantial noise reduction effect. In addition, an essential component of floor construction is heating piping for winter heating. For heating pipes made of metal or synthetic resin, an elastic sound-absorbing material is first installed on the floor slab surface, and the heating pipes are installed above it. However, since the heating pipes are straight, the worker must carefully install them by bending them to fit the shape of the floor surface to ensure that the heating heat is evenly distributed. Furthermore, since the noise-absorbing pad, which is subject to significant thermal deformation due to the high temperature of the heating pipe material and the synthetic resin material, comes into contact with the heating pipe material, the noise effect is reduced due to the deterioration and hardening of the elastic material caused by the high temperature. Therefore, a configuration is also required to isolate the heating pipe material and the noise-absorbing pad by separating them and pouring mortar between them. When constructing a floor surface by pouring mortar, since the mortar is injected from a localized position on one side into the heating pipes already laid out to match the floor surface, there was a difficult problem in that if the position of the heating pipes was not fixed, the pipes would shift laterally or bend upward due to the upward bending force caused by the heavy weight of the mortar, making it difficult to maintain the designated position. In order to simultaneously solve the aforementioned problems from the past, such as (1) easy installation of heating pipe materials, (2) separation between heating pipe materials and sound-absorbing materials, and (3) fixing the position of heating pipe materials, a flat pad-shaped injection-molded body for heating pipes that can be installed on the floor surface is being widely introduced recently. A conventional drainage pad for heating pipes is provided as an injection-molded synthetic resin body in the shape of a flat pad, having a position fixing means for providing a drainage position and a bending position of a heating pipe above it and inserting a heating pipe material into each position, and a bridge-shaped separation means for separating it from a sound-absorbing pad below, all integrally molded. With this configuration, a drainage pad for heating pipes is installed, and construction is carried out by a worker laying heating pipe materials along designated positions on the drainage pad and inserting and fixing the pipe materials into position fixing means that are typically cut in a "+" shape. Since this allows for very convenient construction, the following configuration has been developed and is known as a general technology in the industry. As described above, the requirements for heating pipe installation pads are as follows, in order to reduce inter-floor noise, facilitate the installation of heating piping materials, and enhance practical economic efficiency. (1) Due to the recent surge in construction costs and labor costs, economic feasibility has become the top priority in construction. Therefore, since the manufacturing cost and material cost of the heating pipe drainage pad must be minimized, it is necessary to minimize the mold manufacturing cost by making the mold for molding synthetic resin material as simple as possible and to reduce raw material costs by minimizing the amount of synthetic resin used in molding. (2) The heating pipe drainage pad must ensure ease of mortar pouring and uniformity of pouring by allowing smooth entry and even dispersion of the sound-absorbing material of the lower elastic material when the final finishing mortar is poured, thereby preventing localized construction defects. (3) In the process of installing pipe materials on the heating pipe installation pad, the connection work between the heating pipe installation pad and the pipe materi
