Abstract

The utility model relates to a floor slab component of building construction. The floor slab component is composed of a frame and a concrete layer, wherein, both sides of the lower part of the fine stone concrete layer are provided with ribs, and the middle is provided with an inward concave slot-shaped structure; the frame which adopts steel wire mesh frame sandwiching plates is contained in a groove of the fine stone concrete layer; prestressed wires are also arranged in the side ribs; thereby, a prestressed reinforced concrete sandwiching compound floor is made. The utility model has the advantages of light self weight, less steel consumption, good mechanical properties, low cost, sound insulation, concealed installation of indoor horizontal pipelines, and space position saving.

Description

Light weight sound-proofing floorslab

The utility model relates to a kind of floor member of building construction.

At present, the floor of building construction generally adopts the armored concrete slab of prefabricated steel concrete porous plate or cast-in-site as supporting part.This main weak point of floor slab structure that with the plain bars is skeleton and layer of concrete constitute is: 1. weight is big, expends steel; 2. sound insulation value is poor, and disturbing appears in floor gap easily up and down; 3. long construction period, the cost height.

The purpose of this utility model is to avoid weak point of the prior art, and provides a kind of from heavy and light, and it is simple and direct to construct, and is convenient to the Light weight sound-proofing floorslab product of concealed installation pipeline.

Can take following technical scheme to realize purpose.Light weight sound-proofing floorslab still is made of skeleton and layer of concrete, but the pea gravel concreten layer has the bathtub construction of rib, middle indent for the both sides, bottom, skeleton adopts the steel wire net rack sandwich sheet, be included in the groove of pea gravel concreten layer, also be provided with compressor wire in the side rib, make prestressed reinforced concrete sandwich composite floor plate.

The relative prior art of the technical program has following advantage and effect:

1. few from heavy and light, steel quantity consumption, mechanical property is good, can reduce building on the whole

Structural cost;

2. have deadening, the phase mutual interference that has solved between the building levels is asked

Topic;

3. the plate core of steel wire net rack sandwich sheet can be excavated the part, and is pre-buried herein warm

Gas, feedwater piping and so on can make indoor horizontal pipeline concealed installation, save the space

The position is of great importance to promoting modernization of the housing industry, and a large amount of the use will

Produce remarkable social benefit and economic benefit.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Fig. 1 is a kind of structural representation of Light weight sound-proofing floorslab,

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is the B-B sectional view of Fig. 2.

Under the prerequisite that satisfies the said structure requirement, in the Light weight sound-proofing floorslab, the specific constructive form of steel wire net rack sandwich sheet, size, the shape of the thickness of pea gravel concreten layer, side rib, groove and the diameter of compressor wire, arrangement mode etc. all can be according to using needs to set, they all have from heavy and light, the multiple functional performance of load-bearing, sound insulation etc. preferably.

The steel wire net rack sandwich sheet has excellent mechanical property and thermal property, and it can adopt the commercially available various existing goods or the goods of other form of structure.Because of its plate core is polystyrene foam plastics or rock cotton board and so on, be easy to when needing pipe laying excavate.

Among the Light weight sound-proofing floorslab embodiment shown in the drawings, its plate body is the precast floor slab structural member that is made of pea gravel concreten layer 1, steel wire net rack sandwich sheet skeleton 2 and compressor wire 3, the pea gravel concreten layer has the bathtub construction of rib, middle indent for the both sides, bottom, the steel wire net rack sandwich sheet is inclusive in the groove of pea gravel concreten layer, and compressor wire is arranged in the side rib.Prefabricated component can be produced by prior art " pre-tensioning system " or other technology, and plate lower rebar concrete is applied prestressing force.This floor install and fix at the construction field (site) and pre-buried pipeline after, smear or spray conventional cement mortar at Ban Dipu, as not needing pre-buried pipeline, cement screedn also can be finished in factory at the bottom of the plate.

Compressor wire 3 adopts  5mm steel wire and plate long parallel, evenly arranges along width in rib, as shown in drawings.The steel wire radical can be selected according to span and load, and general every side 2-4 root gets final product.

Press the Light weight sound-proofing floorslab that accompanying drawing is made, the functional performance resultant effect is good.

Claims (2)

1. Light weight sound-proofing floorslab, be made of skeleton and layer of concrete, it is characterized in that: the pea gravel concreten layer has the bathtub construction of rib, middle indent for the both sides, bottom, and skeleton adopts the steel wire net rack sandwich sheet, be included in the groove of pea gravel concreten layer, also be provided with compressor wire in the side rib.

2. Light weight sound-proofing floorslab as claimed in claim 1 is characterized in that: compressor wire adopts  5mm steel wire and plate long parallel, evenly arranges along width in rib.
