Problems solved by technology

The above-mentioned technology has not only significantly improved the effect of impact sound insulation, but also plays a role in heat preservation, but it is expensive, the construction conditions are relatively harsh, the process is complicated, and the net height of the floor is compressed, so it is still difficult to be widely used in the market

Embodiment 1

[0026] as attached figure 1 As shown in , the sound insulation floor slab of the present invention comprises an ordinary cement mortar leveling layer on the upper floor and a damping mortar plastering layer on the lower floor; the damping mortar plastering layer is laid by sound damping mortar, and the sound damping mortar The ingredients are: sand for construction, rubber granules and fine powder for construction. The sand for construction can be medium sand or fine sand for construction. In this embodiment, the spun yarn is selected, and the fineness of the selected rubber particles is required to be close to that of the spun yarn. The fine powder for construction can be fly ash or talcum powder. Fly ash is selected in this embodiment.

[0027] 60 kilograms of building sand, 20 kilograms of rubber granules and 20 kilograms of building fine powder are prepared for materials. Then carry out paving construction according to the following process steps:

[0028] A: Base tre...

Embodiment 2

[0033] like figure 2 as shown in:

[0034] In this embodiment, first prepare the damping mortar, mix construction sand, rubber particles and construction fine powder according to the weight ratio of 80 kg of construction sand, 10 kg of rubber particles and 10 kg of construction fine powder, and then mix them evenly Add an appropriate amount of water to the damping mortar, stir evenly, and lay it on the treated floor base 1 by the method of ordinary mortar leveling layer to form a damping mortar plastering layer 2, and the thickness of the damping mortar plastering layer can be controlled to 10mm . In order to prevent sound bridges, the damping mortar plaster layer at the corner 5 should be returned to the wall for about 50mm, and its thickness should be gradually reduced from 10mm to 0mm. In order to further reduce the cost, dry cement powder is mixed with construction spun yarn at a ratio of 2:1, and then sieved on the thickness of the damping mortar plaster layer with a 0...

Abstract

A sound insulation floor slab for building and a construction method thereof pertain to the technical fields of building material components and construction. The sound insulation floor slab is characterized by comprising an upper-layer ordinary cement mortar leveling layer and a lower-layer damping mortar floated coat, the damping mortar floated coat is made by laying acoustic damping mortar which comprises the following components by weight percentage: 60%-80% of sand for construction, 5%-20% of rubber grains, and 10-20% of fine powder for construction. The laying method of the sound insulation floor slab is as follows: firstly impurities and sharp objects on the substrate are cleaned off to ensure that the substrate is flat, secondly the damping mortar floated coat is laid and protected by a cement protection layer, and finally the ordinary cement mortar leveling layer is laid on the cement protection layer. The sound insulation floor slab has the advantages of extremely low raw material cost, simple construction process, easy control on the thickness of sound insulation damping layer, and improving the sound insulation for impact sound by about 12dB, and the sound insulation floor slab meets the sound insulation requirement of high performance buildings.

Description

Technical field: [0001] The invention relates to a building sound-insulating floor slab and a laying method thereof, belonging to the technical field of building material components and construction. Background technique: [0002] The energy of solid-state sound has little attenuation in traditional building materials, its propagation speed is faster than that in air, and its propagation distance is very long. The continuous, thick and hard concrete floor has good airborne sound insulation effect, but poor effect on impact sound (solid sound). Therefore, the residents living in the lower floors generally cannot hear the voices of the upper-floor residents, but the sounds of the upper-floor residents dragging tables, children running and jumping, and heels hitting the ground have a great impact on the lower-floor residents. The sound pressure intensity of the impact sound of ordinary residential floor is about 75dB. In order to improve the sound insulation performance of th...
