Description

Apartment flooring with insulation and inter-floor noise prevention function by means of EVA waste and fiber spray material}

The present invention is a construction structure that improves the construction performance of the insulation, sound absorption, dustproof construction of the building, the waste material of the YB synthetic resin foam and elastic polyurethane foam having elasticity in the floor slab of the living room and the floor of the apartment house, 10mm through the grinder Simultaneously spraying under the size and adhesive to form an insulating and dustproof layer, and then spraying the fiber-coated material and adhesive curing agent to block the penetration of cement concrete during the subsequent process with a fine fiber layer. It is a method of increasing the effect of the construction.

Common construction methods for apartment houses include ① foaming polystyrene sheet thickness 20mm, ② light weight concrete thickness 70mm laying, ③ dustproof mat laying, ④ dustproof material spraying, ⑥ anti-vibration mortar, etc., but there are advantages and disadvantages. (Currently, some apartment construction sites are fixing 20mm thick polystyrene foam on the floor slab with cement nails on the floor slab and placing lightweight concrete thickness 60mm in the living room floor, kitchen floor, and bedroom floor. And the inconvenience of the work process, and a lot of construction cost.

Such methods have a problem in that they have two performances of insulation and dustproofing in actual field construction. Insulation plate has problems of dustproof and workability, and dustproof mat has problems of insulation performance and construction method. In addition, in the method of spraying the dustproof material (tire grinding scrap), cement slurry during the construction of lightweight concrete, which is a subsequent process, penetrates between the crosslinked pores of the tire grinding scrap, thereby reducing the effect of the construction.

In addition, the tire grinding scrap dustproof material is a crushed product of waste tires, and the material itself has insufficient thermal insulation performance. On the other hand, YVE and synthetic urethane waste are heat-insulated and dust-proof materials with continuous bubble voids, and have excellent elasticity, tensile strength and light weight.

Therefore, the present invention is to overcome the above-mentioned conventional problems, and after spraying the insulating dustproof material on the floor slab of the apartment house as shown in the representative view (Fig. The cement slurry penetration during the subsequent process is blocked by a fine fiber layer to achieve an improved floor structure of insulation, sound absorption and dustproofing.

1 and 2 is a cross-sectional view of the floor structure of the multi-family house having a heat insulation and dustproof function of the present invention.

(1) Floor slabs between apartments. (2) EVA foaming materials spraying construction.

(3) fibrous spraying materials. (4) light foam concrete.

(5) Deadline mortar. (6) Heating piping.

FIG. 3 is a process of mixing and spraying EVA foaming waste and adhesive after blower transfer, and a process of simultaneously spraying after blower transfer of fiber spraying material and adhesive curing material which is being constructed immediately.

In order to achieve the above object, an additional method of forming an insulation and a dustproof layer on the floor slab between apartment houses is required. The insulation and the dustproof material are transferred simultaneously with the adhesive using an YB synthetic resin foam and an elastic polyurethane foam. Select the thickness according to the purpose of insulated and dustproof by spraying, and then transfer and spray the fiber-spreading material and adhesive using the pressure-feeding fiber-spraying equipment to further spray on the surface of the insulation and dust-proof material. Is shown below. (Attach construction equipment drawing: Drawing 3)

Embodiment 1 Example. (Attachment: 1 copy of test photo)

(One). With the construction equipment according to the above drawings, YB E synthetic resin foam waste material is sprayed 10-15mm thick to the concrete floor slab at the same time as adhesive and dried for 2 days

(2). 7 days of curing after light weight foam concrete 60-70mm

(3). Cut and dig the above construction on the 9th day and examine the surface penetration of cement slurry.

As a result of digging and expansion, the cement slurry of lightweight foam concrete penetrated about 4mm.

Second example of implementation.

(1). The tire crushed particles are mixed with acrylic adhesive, laid on the concrete slab with thickness of 10-15mm, and dried for 3 days.

(2) 5 days after the above construction, lightly foamed concrete thickness 60-70mm, and curing 7 days.

(3). Cut and dig the above construction on the 10th day and examine the surface penetration of cement slurry.

As a result of digging and expansion, cement slurry of lightweight foamed concrete penetrated about 5mm. In particular, the larger the tire crushed particles, the more the cement slurry penetrated.

Third example of implementation.

(1). Inject the construction equipment and the YB synthetic resin foam waste material according to the above drawing into the concrete floor slab at the same time with the adhesive.

(2). After 2 hours of the above-mentioned construction, spray the fiber-spray material with the adhesive curing agent and the thickness of 3-7mm by the construction equipment according to the drawing.

(3). Cut and dig the above construction on the 9th day and examine the surface penetration of cement slurry.

As a result of digging and expanding investigation, cement slurry of lightweight foam concrete was cured on the surface of the fiber-coated material, and the effect of insulation and dustproofing was enhanced.

The main material Yves synthetic resin foam and elastic urethane foam used in the above embodiments, is a material excellent in insulation, sound insulation, vibration-resistant performance with elasticity, resilience, bubble voids.

In addition, the above-mentioned fiber coating material was used as the squirting rock surface, cellulose spraying material, natural fiber waste material, synthetic fiber waste material, etc. The agglomerated particles of the fiber used were small and short to maintain good workability and good surface condition. Simultaneous spraying of fiber spraying materials, adhesives used as curing materials, cement-adhesive mixtures, cement cements, etc., but cement slurry was good for spraying rock wool. Examples of simultaneous spraying with adhesive-cement mixed adhesives, curing time was shortened and economical.

In the above-described test embodiment, it had effective functions such as the insulation of the floor of the apartment house, the vibration sound blocking, the floor filling material, etc., and it was the subsequent process after the construction of the YB synthetic resin foam waste material. The performance deterioration was improved, and the additional construction of the fiber-coated material resulted in the additional effects of the cement slurry penetration, the insulation of the fiber-coated material, and the dust-proofing, and the effect of the floor fill material as thick as the construction thickness was increased.

Since the fiber-coated material exhibits a cross-linked structure of fine fibers, it has an effect of blocking cement slurry like a filtration filter.

In addition, the main material used in the above method is made of the recycling of industrial waste, reducing the economic added benefits and environmental pollution.
