External wall panel system and external wall construction technology

Abstract

The invention relates to the technical field of building construction, and discloses an external wall panel system and an external wall construction technology. The external wall panel system comprises multiple external wall panels which are spliced, wherein the external wall panels comprise skeletons, panel layers, rear panel layers and thermal insulation materials; the panel layers are attachedto certain sides of the skeletons; the rear panel layers are attracted to the other sides of the skeletons; the skeletons are filled with the thermal insulation materials, and the thermal insulation materials are located between the panel layers and the rear panel layers; the external wall panels are connected with an internal wall template through connection assemblies to form a template system of wall pouring. The external wall panel is produced directly by a factory, and then is assembled on site. The external wall panel is used as an external template in a construction period, after construction is conducted, the external wall template is not demolished, and after a building is shaped, the external wall template is used as a thermal insulation board of an external wall. By using the external wall panel system, the wall and the external wall panel are integrated, an external wall template is not needed, working procedures of rack mounting and external wall template demolishing are omitted, and an external wall thermal insulation board and facing do not need to be constructed subsequently and specially, so that construction time and the construction cost are greatly saved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an exterior wall panel system and an exterior wall construction process. Background technique [0002] It is commonly seen that the outer frame needs to be erected in the construction of the outer wall, the concrete formwork is assembled and dismantled, and the outer frame is removed after the main wall is completed. Then install the hanging rail, plaster the wall as a primer, paste and fix the insulation hanging net, apply anti-cracking mortar on the insulation hanging net, level the putty, paint the decorative surface, and finally remove the hanging rail. The door and window construction process is to measure the size of the main wall after construction, install the sub-frame, plaster the opening to close, and complete the exterior wall paint to install the window frame, glass installation, glue, window sash installation, hardware installation and debugging.

Problems solved by technology

This construction method has complicated procedures, many unsafe hidden dangers, and poor working environment.

There is also the problem of cross-job

The various processes are interlocking, and the management and coordination of personnel, life, quality, construction period, materials, procedures, and types of work are difficult, the construction period is long, the construction period plan is difficult to guarantee, the quality is not easy to control, and quality problems are prone to occur and are irreversible

It consumes manpower and materials, and is not environmentally friendly, resulting in high construction costs, poor quality of external walls, low life expectancy, such as cracking, leaking, falling off, and the use of several house maintenance funds for maintenance or new construction during the service life of the house, resulting in serious waste and high maintenance costs.
