Kev tsim kho tshuab ntawm foam concrete cushion

1. Grassroots cleanup

Use broom, shovel and other tools to clean the foam concrete base floor slab, so that there is no debris, hollowing, sanding, falling ash and other phenomena.

2. Elevation control and finished product protection

Before pouring the foam concrete cushion, a foam concrete block with the same proportion as the ground cushion concrete must be prefabricated in advance for ground reinforcement. The prefabricated height of the foam block is the design cushion height -5mm, so that cement mortar can be used on site. Fix the bottom and level it for use. Reinforce the ground according to the design requirements and the +50mm line in the building, and the setting principle is a plum-shaped layout. After the ground is reinforced, Cov khoom tiav thiab cov khoom ib nrab tiav ntawm txheej txheem dhau los yuav tsum tau tiv thaiv (xws li qhov rooj, qab ntug ntawm lub qhov rooj hluav taws, phab ntsa putty tiav, etc.) thiab npog ua ntej kom tsis txhob muaj kab mob.

3. Kev txhawb nqa formwork thiab dej hauv qab

Raws li cov cai tsim, cov formwork sab tau txhawb raws li qhov ntau ntawm foam concrete cushion (xws li: 300xx mm los ntawm qhov rooj chav dej, qhov rooj chav ua noj, hauv paus radiator, etc.). Cov formwork txhawb nqa nrog ntoo square thiab ntoo ntoo bamboo. Yuav tsum xyuas kom cov vaj huam sib luag muaj qhov ntsug thiab flat. Tom qab kev txhawb nqa formwork tiav, dej hauv qab av kom noo. vim foam concrete muaj kev nqus dej tsawg, Tsis pom zoo kom dej ntau dhau kom av ntub.

4. Ua pob zeb ua npuas ncauj

(1) Tsim ua npuas

Kev npaj ua npuas siv tshuab npaj tshwj xeeb (Tshuab tsim npuas ncauj). Txoj cai npaj yog ib txoj kev siv lub cev, Thiab cov tshuaj ua npuas tau muab tso rau hauv tshuab ua npuas ncauj tsis siv neeg los ntawm lub tshuab cua kom npaj tau npuas.

(2) Kev sib xyaw ua khoom

Cov tshuab npaj ua npuas pob zeb sib xyaw raug xaiv raws li qhov xav tau ntawm qhov project. Thawj, Ntxiv dej rau hauv tshuab sib xyaw, Thiab tom qab ntawd muab cement hnyav thiab cov khoom sib xyaw rau hauv tshuab sib xyaw, Thiab lub sijhawm tsis tsawg dua 2 feeb.

(3) Ua kom pob zeb ua npuas ncauj

Tom qab sib tov cov khoom sib xyaw kom sib npaug, Nws sib tov nrog cov tshuaj ua npuas hauv kav dej thiab thauj los ntawm lub twj siab siab mus rau qhov chaw tsim kho rau kev nchuav thiab molding.

5. Kev nchuav molding

Av huv tau muab dej thiab ntub ua ntej, thiab tom qab ntawd cov pob zeb npuas uas npaj tau raug twj ntawm qhov chaw mus rau pem teb tsim kho kom nchuav cushion. Thaum nchuav, ob tus neeg ua haujlwm tib lub sijhawm, thiab ib tus neeg tuav lub raj nchuav rau kev nchuav. Lub cushion hauv av thiab qhov chaw nchuav yuav tsum tau ua kom sib npaug thiab tsim ib zaug. Lwm tus yuav tuav ib lub scraper 2m kom txog thaum kev nchuav mus txog qhov siab calibration, thiab tom qab ntawd du cov pob zeb tshiab nchuav ntawm sab hauv mus rau sab nraud. Tom qab kho, cov khoom tiav yuav tsum tau tiv thaiv thiab txoj kev yuav tsum kaw ib ntus. In order to avoid cross-working damage. Foamed concrete is a viscous fluid, which contains a lot of air and adsorbed water. The discharge pipe shall not come and go in the foam concrete to avoid destroying the air bubbles. The formwork can be removed only after the foam concrete has solidified. The foamed concrete must be used up within 1 hour after it is mixed, otherwise it cannot be used continuously.

6. Finished product protection and maintenance

After the foam concrete cushion is poured, the passages, entrances and other parts must be sealed, and designated for 24-hour care, and only professional maintenance personnel are allowed to enter and exit during the care. After the foamed concrete cushion is poured and formed for 12 rau 14 teev, it shall be maintained by moisturizing and watering, thiab lub sijhawm kho kom qhuav tsis txhob tsawg dua 72 teev.

Kev ntsuas zoo

1. Hom thiab cov lus qhia ntawm pob zeb nplaum yuav tsum ua raws li qauv thiab cov qauv tsim nyog. Rau pob zeb nplaum nplaum uas ua npuas ntawm qhov chaw, kev sib tov yuav tsum ntsuas kom raug thiab sib tov kom sib npaug, thiab nws qhov kev coj cua sov, density, thiab lub zog nias yuav tsum tau pom thiab xa mus tshuaj xyuas.

2. Ua ntej kev tsim kho loj ntawm qhov project, yuav tsum muaj ib qho qauv qhia kev. Qauv tsuas yog txhawb nqa tau hauv thaj chaw loj tom qab qauv thev naus laus zis tau lees paub, thiab lub thawv kuaj yuav tsum khaws cia rau kev kuaj compressive strength thaum tsim qauv, thiab nws tsuas siv tau tom qab nws tau lees paub.

3. The "three inspection system" yuav tsum tau siv nruj thaum txheej txheem tsim kho, i, kev tshuaj xyuas tus kheej, kev tshuaj xyuas sib koom, thiab kev tshuaj xyuas hloov chaw. Qhov txheej txheem tom ntej tsuas ua tau tom qab dhau kev tshuaj xyuas.

4. Dej hauv tsev lossis dej huv yuav tsum siv rau dej tsim vaj tsev. Tsis pub sib tov dej acidic rau hauv cov tshuaj ua npuas kom tsis txhob muaj kev ua tshuaj lom thiab cuam tshuam rau kev ua haujlwm ntawm cov tshuaj ua npuas.

5. Tom qab ntim cov pob zeb npuas lawm, qhov nkag yuav tsum kaw thiab yuav tsum muaj ib tug neeg tshwj xeeb saib xyuas 24 teev. Tsis pub nce mus ua ntej kev teeb tsa kawg. Tom qab muaj zog, yuav tsum xa ib tug neeg tshwj xeeb mus saib xyuas raws sijhawm kom ntseeg tau qhov muaj zog ntawm pob zeb npuas thiab zam kev tawg.

6. Kub ntawm ib puag ncig tsim vaj tsev pob zeb npuas yuav tsum siab dua 5°C, and construction in high temperature weather should be avoided.

Comprehensive comparative analysis

After using foamed concrete as the floor cushion of the residence, there are the following advantages compared with the original design of lightweight aggregate concrete:

(1) It reduces the load on the floor and makes the structure more secure.

(2) Enhance the sound insulation performance between floors and make the design more humane.

(3) It provides good thermal insulation performance for the plumbing pipeline in the cushion, reduces the negative impact of thermal expansion and contraction on the pipeline, and enhances the service life of the pipeline.
