Problems solved by technology

The traditional method often uses re-poured concrete to increase the cross-section of the building components. It is necessary to break out the gaps in the original building components before setting up the formwork and pouring. The construction is difficult and the construction period is long. At the same time, the weight of the building is increased, which seriously affects The load-bearing capacity of the building structure may sometimes cause the center of gravity of the whole building to shift seriously, which is very detrimental to the safety of the main body of the building.

Embodiment 1

[0037] The lightweight foamed concrete building components with a bulk density of 200 kg / m3 are prepared by chemical foaming, and its constituent materials are: Pc32.5 cement: 150 kg, water: 88 kg, small material: 1.5 kg, liquid foaming agent: 8.5 kg, admixture: 5 kg, and the pre-embedded steel bar is 40 meters of Φ12 steel bar.

[0038] Its process steps include:

[0039] 1. Formwork and pre-embedded steel bars;

[0040] 2. Use stirring equipment to stir the slurry;

[0041] 3. After the slurry is evenly stirred, add liquid foaming agent into the mixer;

[0042] 4. After adding the liquid foaming agent, stir for 3 seconds, then reverse the mixer for 5 seconds;

[0043] 5. Put the material into the mold;

[0044] 6. After the concrete is formed, cut the surface evenly, and then remove the formwork and put it into the stack for maintenance;

[0045] 7. Groove the lower part of the building components to make pre-embedded holes, and ship.

[0046] The mixing equipment is a...

Embodiment 2

[0050] The lightweight foamed concrete building components with a bulk density of 250 kg / m3 are prepared by chemical foaming. The components include: Pc32.5 cement: 200 kg, water: 115 kg, small material: 1.8 kg, liquid foaming agent: 10 kg, admixture: 6.5 kg, and the pre-embedded steel bar is 59 meters of Φ12 steel bar.

[0051] The difference between the process steps and the first embodiment is: after adding the liquid foaming agent, stir for 5 seconds, and then reverse the mixer for 9 seconds.

[0052]

Embodiment 3

[0054] The lightweight foamed concrete building components with a volume density of 350kg / m3 are prepared by physical foaming. The components are: cement: 250kg, fly ash: 30kg, water: 80kg, stone powder: 1.5kg, foaming agent: 3kg, pre-embedded The reinforcement is 80 meters of Φ12 reinforcement.

[0055] Its process steps include:

[0056] 1. Support mold, pre-embedded steel bar;

[0057] 2. Prepare foam concrete with foam concrete equipment;

[0058] 3. Pouring and scraping the surface;

[0059] 4. Conservation for 3 days;

[0060] 5. Lifting mold transportation, stacking maintenance;

[0061] 6. Groove the lower part of the building components to make pre-embedded holes, and ship.

Abstract

The invention discloses a light-weight foamed concrete building component and a production method thereof. The light-weight foamed concrete building component comprises the following materials in parts by weight: 100-300 parts of cement, 50-150 parts of water and 1-20 parts of a foaming agent. Buried steel bars are also arranged inside the light-weight foamed concrete building component. The production method of the light-weight foamed concrete building component comprises a chemical foaming production method and a physical foaming production method. The invention provides a novel building component for increasing the sectional area of the conventional building component, so that the construction difficulty can be effectively reduced, the gain of the gravity of a building and the influence on the gravity center of the building are greatly reduced, and the safety and the stability of a building main body structure are effectively guaranteed. Various building components can be produced according to demands for decoration of buildings and can be also manufactured in a factory in batches; in-site form erecting and pouring construction can be realized; the adaptability is high; the application range is wide; the light-weight foamed concrete building component has extremely high environment-friendly and social benefits and deserves to be widely popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of lightweight components for architectural decoration, and in particular relates to a lightweight foam concrete building component and a production method thereof. technical background [0002] After the main body of the building is completed, if the section of some parts of the main body is insufficient or the shape and structure are not suitable during decoration, in order to meet the structural requirements or increase the aesthetic feeling of the building, it is necessary to increase the section of the building components. The traditional method often uses re-poured concrete to increase the cross-section of the building components. It is necessary to break out the gaps in the original building components before setting up the formwork and pouring. The construction is difficult and the construction period is long. At the same time, the weight of the building is increased, which seriously affects The load...
