Abstract
The invention discloses a production method of a saving type assembly wallboard, which comprises an external wallboard, a middle layer wallboard, an internal wallboard, a concave interface, a convex interface and a reticular metal framework, wherein the outer layer wall board adopts a foaming concrete layer, has good heat preservation, fire prevention and sound insulation properties, meanwhile, the wallboard has the advantages of good integrity and good environmental protection, simultaneously, the fiber is added in the preparation process, the toughness is improved, the splitting tensile strength is increased, the middle-layer wallboard is a high-strength concrete wallboard, and utilizes the plant fiber, which is more beneficial to resource saving and has good environmental protection performance, and finally the fire retardant is added into the inner wall board, so that the internal safety performance of the wall board is further improved, the invention is provided with the net-shaped metal framework inside to lead the outer, middle and inner layers of wall boards to be connected together more closely, thus effectively solving the problems that the functional and physical properties of the assembled wall board still have many limitations and defects.
Description
Technical Field
The invention relates to the technical field of building materials, in particular to a production method of an economical assembly type wallboard.
Background
The prefabricated wallboard is mainly prefabricated components produced in factories, a house building is designed and built in a field assembly mode, the assembly method of the components generally comprises field post-cast laminated concrete, steel bar anchoring post-cast concrete connection and the like, the steel bar connection can adopt methods of sleeve grouting connection, welding, mechanical connection, reserved hole lap joint connection and the like, the prefabricated house has many hidden dangers and defects influencing the safety and normal use of the structure due to poor structural integrity, leakage, floor slab cracks and the like, and is gradually replaced by a cast-in-place concrete structure, but the prefabricated wallboard gradually develops in a better direction along with the application of the current emerging prefabricated concrete structure.
Compared with a cast-in-place construction method, the assembly type structure basically belongs to green construction, the green construction refers to construction, under the premise of ensuring the basic requirements of quality, safety and the like, through scientific management and technical progress, resources are saved to the maximum extent, construction activities with negative influences on the environment are reduced, four-section one-environment protection (energy saving, land saving, water saving, material saving and environment protection) is realized, the use of the assembly type wall plate is more favorable for reducing the negative influences on the environment, including reducing noise, preventing dust raising, reducing environmental pollution, cleaning transportation, reducing site interference, saving water, electricity, materials and other resources and energy, and the principle of sustainable development is followed.
However, because the functionality and physical properties of the assembled wallboard still have many limitations and deficiencies, the application of other prefabricated building systems is very few except that the assembled single-layer industrial factory building system is widely applied at present, and the application degree is narrow and small due to insufficient study on the seismic performance of the prefabricated structure, poor fireproof and flame-retardant effects, poor sound insulation effects and the like, and the prefabricated wallboard is in a state of being in a stagnation for a long time.
Disclosure of Invention
Technical problem to be solved
Aiming at the defects of the prior art, the invention provides a production method of an economical assembly wallboard, which is used for solving the problems that the functional performance and the physical performance of the assembly wallboard still have many limitations and defects, the engineering application of other prefabricated assembly building systems is very few except the wide application of the assembly single-layer industrial factory building system, the application degree is narrow and the prefabricated structure is in a state of no stagnation for a long time due to insufficient study on the earthquake resistance of the prefabricated structure, poor fireproof and flame-retardant effects, poor sound insulation effects and the like.
(II) technical scheme
A production method of an economical assembly wallboard, which comprises an external wallboard, a middle layer wallboard, an internal wallboard, a concave interface, a convex interface and a reticular metal framework, comprises the following steps:
firstly, cleaning the wallboard mould, airing, assembling and forming the wallboard mould, then uniformly coating a release agent at each position in the wallboard mould, and placing the wallboard mould on a horizontal mould table;
secondly, laying a net-shaped metal framework at the central position inside the wallboard die processed in the first step;
step three, preparing an external wall panel:
the external wall panel is prepared from the following raw materials in parts by weight: 150 portions of Portland cement, 10 to 30 portions of expanded perlite, 10 to 30 portions of fly ash, 1 to 3 portions of inorganic fiber, 5 to 10 portions of hydrogen peroxide, 0.5 to 1 portion of foam stabilizer, 0.5 to 1.5 portions of foam regulator, 0.5 to 1.5 portions of water reducer and 60 to 70 portions of water;
the preparation process of the external wall panel comprises the following steps:
