Embodiment Construction

[0031] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0032] see Figure 1-4 , a method for preparing a prefabricated foam concrete slab enclosure wall, comprising the following steps:

[0033] 1) Preparation of foam: Use air pump to add air, add proportionally weighed water and foaming agent into the foam machine, pressurize it to 0.5-1.5Mpa by the air pump, and then prepare fine, uniform, good viscosity and stable foam by the foam machine the foam;

[0034] As preferably, the step 1) is pressurized to 0.8Mpa by an air pump;

[0035] 2) Prefabricated foam concrete forming plate 1: put various raw materials into the machine and stir, then add the above foam, carry out evenly cast-in-place construction or mold molding of the built-in steel bars, smooth it after standing for 25 minutes, and put it in after standing for one day From the standard curing room to the test age, the foamed concrete forming...

Abstract

The invention discloses preparation and construction methods of an assembled foam concrete slab enclosure wall. The preparation method of the assembled foam concrete slab enclosure wall comprises the following steps: preparing foam; prefabricating foam concrete formed slabs; preparing ECC slurry A; preparing ECC slurry B. The construction method of the assembled foam concrete slab enclosure wall comprises the following steps: leaning the prefabricated foam concrete formed slabs on a wallboard, point-fixing by using boat nails, and meanwhile inserting in sequence; filling grooves; inserting rebars through holes formed in the wallboard; removing surface dust; plastering; watering for curing. Deformability, fire resistance, anti-cracking ability, dissipation capacity, erosion resistance, shock resistance, water absorption resistance, shear resistance and bearing capacity of the assembled foam concrete slab enclosure wall are increased by 40 percent that those before reinforcing, and meanwhile heat preservation and sound insulation properties of foam concrete are further enhanced.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a preparation and construction method of an assembled foam concrete slab enclosure wall. Background technique [0002] The development of prefabricated buildings is one of the key points of construction industry reform in recent years. The production technology of foam concrete wall panels as enclosure components is very mature, and it will play a greater role in the housing industrialization industry in the future. The construction methods of foam concrete wall panels include the construction method of inserting steel bars and the construction method of bolt fixing. Among them, the construction method of inserting steel bars is more convenient in design, processing and installation. At the same time, as a new type of energy-saving and environmentally friendly building material, foam concrete has been researched and developed by scholars at home and abroad. Foam concrete h...
