Description
Technical Field
The invention particularly relates to a prefabricated multi-face connecting monomer, a masonry wall frame and an assembly method thereof.
Background
Development of the prefabricated building is crucial to the progress of building industrialization, at present, the development technology of prefabricated horizontal components (such as floors and beams) tends to be perfect, and the development of prefabricated vertical components (outer walls) is slow, compared with the traditional cast-in-place technology, the prefabricated outer walls are high in cost, and have no market application prospect. The cost disadvantage is mainly caused by the following reasons:
the existing prefabricated assembly type adopts an outer wall integral pouring process, a large steel mold with high cost is needed, different building designs need different types of large steel molds, and the input cost is extremely high;
the whole exterior wall is poured, the occupied area of the prefabricated part is large, and the prefabricated part needs long maintenance to improve the strength, so that the preparation time of the prefabricated part is long, the turnover rate of products is low, and the turnover cost is increased;
the whole external wall has large size, so that the number of components is limited during transportation, safety protection measures for the components are additionally added, the problems of cracking and falling of the wallboard are prevented, the transportation efficiency is seriously influenced, and the additional cost is increased;
at present, the whole outer wall is connected in the field in a manner of adopting grouting sleeve connection (because the grouting sleeve connection is relatively safe and the quality is relatively stable), however, the requirements of the grouting sleeve connection on the manufacturing precision and the assembly precision of the outer wall are extremely high, and the intelligent assembly precision can not be realized at present, so that the assembly can be realized only by bending the reinforced bars of the prefabricated outer wall by manpower in the field, the construction period is prolonged, the grouting quality can be ensured only by adopting the pressurized construction, and the cost is increased.
In view of the above problems, there is a scheme of "standardizing the size of the building exterior wall, and when the size of the exterior wall is sufficiently large, it will form a cost advantage" to reduce the cost. However, the general performance of actual operation is lacking, the building design pursues various styles, which are contradictory with the standardized component sizes, the contradiction between the related structural components and the processing mode is not solved, and all the buildings cannot be built into the same style because the standardized component sizes can obtain cost advantages, which are contradictory with the building essence concept, so the standardized component sizes are not feasible on the basis of the existing prefabricated assembly type outer wall technology.
Aiming at the high cost problems caused by contradiction between prefabricated outer wall standardization and building diversity, low turnover and transportation assembly efficiency, high assembly precision requirement and the like, at present, a masonry structure mostly adopts a manual masonry mode, the efficiency and the construction quality are uneven, and the low cost advantage of the masonry outer wall is gradually reduced along with the rise of the labor cost.
The existing masonry form adopts a form of coating a mortar layer among prefabricated building blocks, and as the elastic modulus and the strength of the mortar are greatly different from those of prefabricated multi-face connecting monomers, higher requirements are provided for the thickness uniformity of the mortar layer. Engineering practice and experimental research show that the larger the thickness of the mortar layer is, the worse the uniformity of the mortar layer is, and uneven sedimentation is easy to cause, so that the cracking problem is caused. For this reason, machine painting, i.e. 3D printing of the mortar layer, has been proposed again to reduce the thickness of the mortar layer. Practice shows that although the thickness of the mortar layer can be reduced by 3D printing, the uniformity difference of the mortar layer is obvious, especially the mortar layer at the position of the just-started spraying and the position of the just-ended spraying is easy to form the problem of less or more materials, thereby influencing the uniformity between layers; and the quality requirement of 3D printing on mortar is higher, and the cost is further increased.
