Abstract

To address the problem of burdensome of site work on an upper floor exhibiting a sound-proof effect and a heat-insulation effect.SOLUTION: Joist materials 2 and 2 are incorporated in the upper surface of a panel body 1 made of a foam resin band exhibiting a heat-insulation effect, recesses 3, 3 are formed in parts of the upper surface of the panel body 1 other than the joist materials 2 and 2, an adhesive C is applied on the backside of the upper floor substrate panel having sound-proof plates 4, 4 buried in the recesses 3, 3, and placing on the upper surface of an upper floor substrate B. By repeating this process, a plurality of upper floor substrate panels are fully laid, each upper floor substrate panel is fixed to the upper surface of the upper floor substrate B by the adhesive C, and each a floor finishing material D is fully laid on the upper floor substrate panel. Thus, only by fixing the upper floor substrate panels on the normal upper floor substrate B by the adhesive C, a sound-proof / heat-insulation substrate E of an upper floor F can be completed.SELECTED DRAWING: Figure 2

Description

[Technical Field]

[0001] This relates to base panels used on the floors of the second floor and above (hereinafter referred to as upper floors) in wooden multi-story buildings, and to a soundproofing and heat insulation construction method using said upper floor base panels. [Background technology]

[0002] Conventionally, in the case of upper floors, a structure has been seen in which thick sound-absorbing material, generally made of urethane or polystyrene foam, is laid between the joists, and then a sound-insulating mat or the like is laid on top of the base board laid on top of that, and then a floor finishing material is laid on top of the sound-insulating mat (for example, see Non-Patent Document 1).

[0003] Furthermore, by using expanded polyethylene foam (see, for example, Non-Patent Document 2), which has soundproofing and excellent heat insulation properties, instead of the above-mentioned sound-absorbing material, it is possible to construct upper floors with soundproofing and heat insulation effects.

[0005] However, the above-mentioned conventional technology had problems that needed to be solved, such as the need to cut the material on-site to fit the dimensions between the joists and the need to lay sound-insulating mats. [Means for solving the problem]

[0006] In consideration of the problem that on-site work is tedious when constructing upper floors with soundproofing and heat-insulating effects based on the above-mentioned conventional technology, the present invention solves the above-mentioned problem by incorporating floor joists into the upper surface of a panel body made of foamed resin and having heat-insulating effects, forming recesses on the upper surface of the panel body in areas other than the floor joists, and applying adhesive to the backside of an upper floor underlayment panel with a soundproofing board fitted into the recess, and then placing the panel on the upper floor underlayment, repeating this process until multiple upper floor underlayment panels are laid on the upper floor underlayment, and each upper floor underlayment panel is fixed to the upper surface of the upper floor underlayment with adhesive, and floor finishing material is laid on the upper floor underlayment panels, thereby making it possible to complete the soundproofing and heat-insulating underlayment for the upper floor simply by fixing multiple upper floor underlayment panels to a normal floor underlayment with adhesive, thereby solving the above-mentioned problem. [Effects of the Invention]

[0007] In short, the present invention involves incorporating floor joists into the upper surface of a panel body made of foamed resin and having insulating properties, forming recesses in areas of the upper surface of the panel body other than the floor joists, and fitting soundproofing panels into the recesses, so that the upper floor can be provided with soundproofing and insulating effects using only this upper floor floor underlayment panel, and because the soundproofing panel is on the upper surface of the panel body, it is closer to the source of the sound, so it can efficiently absorb sound before it diffuses.

[0008] The method includes the steps of repeatedly placing upper floor underlayment panels as described in claim 1, which have adhesive applied to their backsides, on the upper surface of the upper floor underlayment, to lay multiple upper floor underlayment panels on the upper floor underlayment and fix each upper floor underlayment panel to the upper surface of the upper floor underlayment with the adhesive, and the step of laying floor finishing material on the upper floor underlayment panels on the soundproof and heat-insulating underlayment constructed in this step, thereby providing great practical effects such as making it possible to easily construct upper floors that have soundproofing and heat-insulating effects.

[Figure 1(b)] FIG. 2 is a central cross-sectional view of the upper floor underfloor panel of FIG. 1(a). [Figure 2] FIG. 1(b) is a cross-sectional view of the vicinity of the wall of an upper floor using the upper floor underlayment panel of FIG. [Figure 3] FIG. 1(b) is a cross-sectional view of the vicinity of the frame of an upper floor using the upper floor underlayment panel of FIG. 1(a). DETAILED DESCRIPTION OF THE INVENTION

[0010] As shown in Figures 1(a) and 1(b), the upper floor floor underlay panel of the present invention is provided with soundproofing and heat insulation effects for the upper floor by laying multiple panels on the upper floor floor underlay B. The panel body 1 is made of a foamed resin such as polystyrene and has a heat insulating effect, and multiple, specifically two, joists 2, 2 are incorporated into the upper surface of the panel body 1, which has been processed to have a mating surface, and the upper surfaces of the joists 2, 2 are flush with the upper surface of the panel body 1. Recesses 3, 3... are formed on the upper surface of the panel body 1 in areas other than the joists 2, 2, and plate-shaped soundproofing materials 4, 4... made of a material with soundproofing properties such as urethane or felt are fitted into the recesses 3, 3..., and the upper surfaces of the soundproofing panels 4, 4... and the upper surface of the panel body 1 are flush with each other.

[0011] Although there are two joists 2, 2 in the drawing, there may be one or three or more depending on the size of the panel body 1.

[0012] Then, the upper floor underlayment panel is placed on the top surface of the upper floor underlayment B after applying adhesive C to the backside, and the underside of the panel body 1 is fixed to the upper floor underlayment B. This process is repeated until multiple upper floor underlayment panels are laid regularly and without gaps on the upper floor underlayment B, cutting the upper floor underlayment panels as needed, and floor finishing material D is laid on this soundproofing and heat-insulating underlayment E to easily construct an upper floor F with soundproofing and heat-insulating effects, as shown in Figures 2 and 3, and baseboards H are installed at the inside corners of the wall and upper floor F.

[0013] In detail, as shown in Figure 2, edge joists G are installed on the wall side parallel to the floor joists 2, 2, with their top surfaces aligned with the top surfaces of the floor joists 2, 2, and the ends of the floor finishing material D are fixed to the edge joists G, thereby preventing the ends of the floor finishing material D from sinking or lifting up.

[0014] At the step at the boundary between the area where soundproofing and heat insulating base E is constructed and the area where it is not constructed, as shown in Figure 3, edge joists Ga similar to those in Figure 2 are installed on the inside of frame I, and the ends of floor finishing material D are fixed to edge joists G, thereby preventing the ends of floor finishing material D from sinking or lifting up.

[0015] Furthermore, although the upper floor floor substructure B is shown in the drawing to be composed of joists and subfloor boards, it may be composed of only subfloor boards (structural plywood), and although the floor finishing material D is shown in the drawing to have a two-layer structure with a finishing subfloor material, it may be composed of a single layer structure of only the floor finishing material D, and the floor finishing material D may be directly fixed to the joists 2, 2 with nails or the like.
