Description

Wall Exterior Prefabricated Unit Integrated Composite Panel and Its Connection Structure

technical field

The utility model belongs to a curtain wall plate and its connection structure of a building, and is especially suitable for assembled wall panels and its connection structure of various regular or irregular shaped exterior decorative panel curtain walls.

Background technique

At present, the decorative panel curtain wall outside the wall is installed by frame curtain wall or direct wet pasting. All components are installed sequentially on the construction site. The installation process is cumbersome and the efficiency is relatively low, especially when irregular facade decoration is used. For permanent curtain walls, the installation process is more complicated, and may even be impossible to achieve due to the limited size of the material. At the same time, due to the many joints between the decorative panels, water leakage is very easy to occur, and the waterproof effect is poor. After the external thermal insulation material is installed, before the final curtain wall is completed, it is prone to moisture when exposed to rain and snow, which greatly affects the thermal insulation effect.

Utility model content

The technical problem solved by the utility model is to provide the integrated composite plate of the wall external decoration assembly unit and its connection structure, which solves the technical problems of low assembly rate and complicated construction caused by the irregular splicing of the external decorative panels of the curtain wall ; It effectively improves the assembly rate of the exterior decorative panels of the building wall, and simultaneously solves the problems of waterproofing and heat preservation.

The basic technical solution of the utility model is: a plurality of outer decorative panels are fixed on a unit steel frame through a decorative panel hanger, the unit steel frame is a keel frame composed of a longitudinal main keel and a transverse secondary keel, and the outer The waterproof backboard is fully paved between the decorative board and the unit steel frame, and the waterproof backboard is fixedly installed on the dragon frame.

As an optimization, an insulation layer can be added to the above scheme, and the technical scheme is: insulation cotton is pasted behind the waterproof backboard. The thickness of the insulation cotton is determined according to the energy-saving calculation of the actual project. The main keel and the secondary keel are filled with thermal insulation cotton.

Based on the above technical features: the main keel is provided with a unit plate hooking member. That is, the unit plate articulated member can be processed in a factory as a part of the composite plate of the present invention.

When the prefabricated unit integrated composite plate of the wall exterior decoration itself does not have the unit plate hanging member, the connection structure of the composite plate is: a connector is provided on the exterior wall structure of the main building, and the prefabricated unit integrated composite panel of the wall exterior decoration There is a unit plate hanging component behind the main keel of the plate, and the assembled unit integrated composite plate of the wall exterior is fixed on the main exterior wall structure of the building after being connected by the unit plate hanging component and the connector; the sealant fills the adjacent The gap between the waterproof backboards of the prefabricated units of the wall exterior finish integrated composite panels. In this case, since the unit plate articulated components are not part of the prefabricated unit integrated composite plate of the wall exterior finish, during construction, it is necessary to add unit plate articulated components to the composite plate on site, and then hang it to the building On the main exterior wall structure.

When the prefabricated unit-integrated composite plate of the wall exterior decoration itself has a unit-plate hooking member, the connection structure of the composite plate is: a connector is provided on the exterior wall structure of the building main body, and the prefabricated unit integrated composite plate of the wall exterior decoration After the unit plate is hooked and connected to the connecting piece, it is fixed on the outer wall structure of the main building; the sealant fills the gap between the waterproof backboards of the assembled unit integrated composite plate on the exterior surface of the adjacent wall. In this case, since the unit panel hooking member has been used as a component of the wall exterior assembly unit integrated composite panel, during construction, it can be directly hung on the main exterior wall structure of the building on site.

In the utility model, the outer decorative panels can be cut at will, can be spliced and fixed in any combination on the unit steel frame. The prefabricated unit integrated composite plate of the wall exterior decoration is assembled in the factory, which improves the prefabricated assembly rate and assembly quality. Sealants or rubber strips are no longer used to seal the exterior decorative panels, but the waterproof backplane behind the exterior decorative panels is used as a waterproof layer; the waterproof backplane can be made of aluminum alloy plates or galvanized steel sheets or other existing technologies. Waterproof board. The sealant is set between the adjacent waterproof backplanes, and is not directly exposed to sunlight, so as to slow down the aging speed of the sealant and achieve a better waterproof effect. Free cutting and combination provide the conditions to make the integrated composite plate of prefabricated unit of wall exterior decoration with rich and colorful appearance. Insulation cotton is pasted behind the waterproof backboard, and the main keel and sub keel are filled with insulation cotton. The insulation system can be integrated into the composite plate to prevent the insulation cotton from being soaked by rainwater during installation.

Utilizing the connection structure of the utility model, it is possible to realize the random cutting of the outer decorative boards, and the shapes are rich; the waterproof is realized through the backing waterproof backboard, which is reliable, safe and effective, and prevents the outer decorative boards from being polluted by the sealant; The exterior decorative panels form a large composite panel, which is processed in a factory, with high processing quality, good thermal insulation effect, and high installation efficiency; the quality of the entire curtain wall can be greatly improved.
