CN2915987Y - High-damping concrete sound-insulating floor slab - Google Patents

Abstract

The utility model relates to a high-damping concrete sound-insulating floor slab. The utility model is adopted that the common concrete is on the upper layer and a wire netting is on the lower layer. The high-damping concrete is on the layer below the wire netting and the high-damping concrete contains common concrete and high molecular polymers such as carboxylic styrene butadiene latex. The cement-polymer ratio is 5 to 30%, which makes the upper layer compression region and the lower layer tension region. The defect that the performance of sound insulation and earthquake insulation of the common concrete floor slab of the prior art is worse and the cast-in-place concrete floor slab extremely easily cracks to make the defect that the performance of sound insulation and earthquake insulation of floor slab is worse because of reasons of design, construction and the self contraction of the materials, etc. The high-damping concrete sound-insulating floor slab of the utility model reinforces the damping characteristics of the whole floor slab, effectively insulates sounds and earthquakes, has strong deformation abilities, can work without cracks, the steel wire mesh is not also easily rust, has good durability, the utility model not only can be produced in mass in plants, but also can be cast on site. The high-damping concrete blends with the common concrete on the upper layer and the compatibility is good.

Description

The high damping concrete soundproof floors

Technical field

The utility model relates to a kind of floor, particularly a kind of high damping concrete soundproof floors.

Background technology

Before the present utility model, the building floor that is used for separating floor normally adds concrete structure with plain bars or wire gauze, its sound insulation, isolation property are relatively poor, cause sound and vibrations very easily to propagate into contiguous floors and next-door neighbor, the office and the household that seriously have influence on the next-door neighbor have a rest.In addition, owing to reasons such as design, construction and material self contractions, cast-in-place ordinary concrete floor very easily ftractures, and has more increased the weight of the sound insulation of floor, the defective of isolation property difference.This has become common construction quality chronic disease.

Summary of the invention

The purpose of this utility model just is to overcome the defective of above-mentioned ordinary reinforced concrete sound isolation of floor, isolation property difference, design, a kind of high damping concrete floor with good sound insulation, isolation property of development.

The technical solution of the utility model is:

The high damping concrete soundproof floors has ordinary concrete, wire lath, and its major technique is characterised in that top one deck is an ordinary concrete, is wire lath below, and one deck is the high damping concrete below wire lath.

Advantage of the present utility model and effect are to add high molecular polymer in floor part ordinary concrete, utilize the high damping concrete to have good deformation performance, improved the counter-bending ability of floor, solved ordinary concrete floor defective easy to crack effectively, increase substantially the damping characteristic of floor simultaneously, and then reached the purpose of sound insulation, shock insulation.Be in particular in that the high damping concrete that utilizes floor lower floor has strengthened the damping characteristic of whole floor, effectively sound insulation, shock insulation, high damping concrete deformation ability is strong, reduces the generation of floor shrinkage crack, is not with crack work, reinforcing bar also is difficult for corrosion, excellent in durability both can be produced in batches in factory, but also cast on-site, high damping concrete and upper strata ordinary concrete combine together, and be compatible good.The utility model is simple in structure, easy to make, and cost is not high yet.

The specific embodiment

As shown in Figure 1, above one deck be ordinary concrete 1, the centre is in length and breadth to wire lath 3 (or gauze wire cloth), bottom one deck is a high damping concrete 2; High damping concrete 2 is to be made of adding high molecular polymer such as two kinds of components of carboxylic styrene butadiene latex in the ordinary concrete, and polymer cement ratio is 5～30%. Strengthen the intensity of floor in length and breadth to wire lath 3; High damping concrete 2 these one decks account for 1/3rd to 2/3rds of whole slab thickness.During concrete the making, at factory or scene, first colligation lays in length and breadth to wire lath 3, and high damping concrete 2 is cast in the lower floor of floor and then cast ordinary concrete 1.

In the utility model, top ordinary concrete 1 this one deck is a pressure zone, and following high damping concrete 2 these one decks are the tensile region, have decomposed the bearing capacity of floor, and its resistance to compression, resistance to tension are strengthened.
