Description
Technical Field
The invention relates to the field of building materials, in particular to high-viscosity special mortar for an assembly type building and a preparation method thereof.
Background
Buildings assembled from prefabricated elements at the site are called fabricated buildings. The construction method is divided into five types, namely building block buildings, plate buildings, box buildings, framework plate buildings, lifting plate and rising building and the like according to the form and the construction method of the prefabricated part; the prefabricated building components are transported to a construction site, the building can be manufactured in a complete set in batches like machine production, the types of the components mainly comprise external wall panels, internal wall panels, laminated slabs, balconies, air conditioning panels, stairs, prefabricated beams, prefabricated columns and the like, the standardization of design and the informatization of management are realized, the more standard the components are, the higher the production efficiency is, the lower the corresponding component cost is, the digital management of a factory is matched, the higher the cost performance of the whole assembly type building is, the assembly is finished, and the method has the characteristics that a large number of building components are produced and processed in a workshop, the building and decoration integrated design and construction are adopted, the decoration can be synchronously carried out along with the main construction in an ideal state, a large amount of assembly operation is carried out on site, the cast-in-place operation is greatly reduced, the requirements of green buildings are met, energy conservation and environmental protection are realized, and the like.
However, the fabricated building is not integrally formed, when the components are assembled and assembled, the defects of unattractive gaps, easy damage of side corners and corners, uneven stress deformation, deformation cracks and the like are easily caused, and the fabricated building becomes a hotbed for breeding pests, weeds and the like and is difficult to clean.
Aiming at the current situation, special mortar particularly suitable for the connection of assembled members is developed, and in order to facilitate the connection construction and repair of damaged parts, the special mortar also needs to have the properties of high viscosity, member permeability, tensile shear deformation resistance and the like, and meet the special performance requirements of corners or joints.
High-adhesion silane modified polyether sealant is added into high-viscosity special mortar for the fabricated building reinforced by biological glue, and a high-viscosity modified asphalt thin layer is covered by an auxiliary tool, so that better structural performance, appearance quality and portability and convenience of construction can be realized under a special construction process; according to the application, the biological glue reinforced high-viscosity special mortar for the fabricated building is used as a main body, and fabricated building components manufactured by adopting special mortar with the publication numbers of CN108529957A and CN109822039A can be better compatible and combined to form a relatively stable whole which is difficult to damage.
The asphalt thin layer used in the high-viscosity modified asphalt thin layer pavement of the CN102839581A assembled roll (plate) material structure discloses a technology for integrating the asphalt thin layer into factory production and assembled construction; CN110256994A and CN108529957A are both high-viscosity special mortar technologies, have small thermal deformation and are not easy to crack, but can crack under the influence of long-term thermal expansion and cold contraction, particularly, the cracks are difficult to avoid at a component joint part and a corner angle part with concentrated stress, although an asphalt thin layer has an effect of overcoming the cracks, the bonding property of the asphalt layer and the high-viscosity mortar is poor, asphalt materials are not easy to disperse, are easy to dissociate, gather and flow, and are difficult problems of technical personnel in the industry.
Disclosure of Invention
The invention aims to overcome the problems in the prior art and provides the high-viscosity special mortar for the assembly type building and the preparation method thereof, the high-viscosity special mortar can meet the requirement of large-batch quick generation of assembly type building components, has high viscosity and good shaping property after shaping, is convenient for compression molding and quick demolding, greatly improves the molding efficiency and cost, and particularly has convenient construction, good connectivity, high repairing efficiency, long service life and few flaws when components are assembled and repaired after deformation, cracking and damage of the components are prevented.
