Panel unit of building external bounding system

Abstract

The invention relates to the field of building decoration, in particular to a panel unit of a building external bounding system. The panel unit comprises a unit body. Frames are arranged on the periphery of the unit body. The unit body is installed on a building structural beam through an adjustable connecting piece fixedly connected with the frames. The frames are provided with slots and sealing rubber strips. The panel unit has the advantages of being easy to assemble, high in assembly precision, high in industrialization degree, good in anti-seismic property and wind-proof performance, convenient to convey and hoist, and good in heat insulation effect.

Description

technical field [0001] The invention relates to the field of building decoration, in particular to a panel unit of a building outer protection system. Background technique [0002] The unit prefabricated building enclosure system is the outer wall enclosure of the building, which is not load-bearing and hangs up like a curtain, so it is also called "curtain wall". It is a light-weight wall with decorative effect commonly used in modern large and high-rise buildings. body. The construction of the existing unit prefabricated building enclosure system needs to install the keel on the structural beam of the building first, and then install multiple panel units on the keel through connectors, and multiple panel units are spliced ​​into the unit prefabricated building exterior For the protection system, the window installation position is reserved on the panel unit, and the strip window is installed at the strip window installation position after the panel installation is complet...

AI Technical Summary

Problems solved by technology

The existing unit-fabricated building enclosure system has the following disadvantages: (1) Due to the assembly error and the processing error of the panel unit and the connector, the position deviation of the panel unit may occur after installation, and it needs to be aligned and adjusted , and the existing panel units are not easy to align and adjust the position, which affects the overall construction quality of the unit-assembled building envelope system, especially resulting in low flatness of the overall front surface of the unit-assembled building envelope system , it is necessary to carry out secondary treatment such as plastering and painting the exterior surface of the panel units of the building envelope system outdoors, which is time-consuming and laborious; (2) After the existing panel units are installed, the joints of adjacent panel units need to be Glue at the place for sealing and waterproof treatment, because it is on-site operation, the construction quality is difficult to guarantee; (3) The existing panel unit has low strength, low earthquake resistance, windproof performance, and heavy weight, which is not easy to transport and hoist; (4) The current Some unit prefabricated building enclosure systems have poor thermal insulation effect; (5) The existing unit prefabricated building enclosure systems reserve the installation position of the strip window on the panel unit, and install the panel unit after the installation of the panel unit during construction. Strip windows, due to on-site construction, the quality is difficult to guarantee; (6) The strip windows of the existing unit-fabricated building envelope system cannot cross floors (supplement the benefits of cross-story)
