Fabricated building outer wall and construction method thereof

Abstract

The invention belongs to the technical field of building construction, and discloses a fabricated building outer wall and a construction method thereof.The fabricated building outer wall is provided with a composite board on the outer surface of a partition wall keel, and a center-penetrating keel is arranged in the partition wall keel. A junction box is embedded in the composite board, and a flame-retardant board is arranged between the composite board and the partition wall keel. The flame-retardant plate is provided with a frame body plate, a transverse inserting groove, a vertical inserting groove, an inserting hole and a flame-retardant particle containing cavity are formed in the upper side of the frame body plate, and flame-retardant particles are contained in the flame-retardant particle containing cavity. The transverse inserting grooves and the vertical inserting grooves are connected with the upper frame body plate inserting plates in an inserting mode, and fixing columns fixed to the four corners of the upper frame body plate are inserted into the inserting holes. Machining procedures are reduced, the thickness and the weight of the partition wall are reduced, the center-penetrating keel is provided with a pipeline channel, arrangement of pipelines and wires is facilitated, and the problems of disordered wiring and troublesome later maintenance are solved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a prefabricated building exterior wall and a construction method thereof. Background technique [0002] At present, most of the exterior walls of prefabricated buildings on the market use autoclaved aerated concrete hanging panels, which are heavy and inflexible in size, and cannot well solve the problems of fireproof cladding of prefabricated building steel components. The other one uses block-type exterior walls, and the construction speed is slow, which cannot solve the problem of assembly rate. There are also some building exterior walls that have the advantage of being assembled, but they can only be used as a decorative surface layer and cannot bear the building envelope. [0003] Usually, the composite panels that are divided into blocks are docked and stacked to form a larger flat wall. Affected by factors such as temperature difference and humi...

Problems solved by technology

Once cracks occur, it is difficult to repair, and it will affect product quality and increase maintenance costs

[0004] Through the above analysis, the problems and defects of the existing technology are: cracks are easy to occur at the joints of the plates and at the overlapping and lap joints of the plates. Once the cracks are formed, it is difficult to repair, and it will affect the product quality and increase the maintenance cost.
