## Background
This application claims the benefit of Taiwan patent application No. 105119054, filed on Jun. 17, 2016, the entire contents of which are incorporated herein by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a composite wall assembly, and more particularly to a composite wall assembly that provides a hollow space for improving effects on environmental protection, energy saving, and heat insulation.
2. Description of Related Art
A wall assembly of a building has an outer wall, an inner wall, and a space. The inner wall is mounted on and is connected to an inner surface of the outer wall. The inner wall has multiple supporting pillars deposited at spaced intervals. Each supporting pillar has multiple through holes deposited at spaced intervals. The inner wall has an inner wall panel. The inner wall panel is mounted on the supporting pillars. The space is formed between the inner wall and the outer wall, and is in communication with the through holes of the supporting pillars for accommodating the water pipelines and the electricity pipelines.
In the construction process, grouting is started after the water pipelines and electricity pipelines are installed, and following grouting, polishing is done to complete the construction process. The construction period is long, during which the polishing work may cause air pollution. In addition, since Taiwan is located on the seismic belt, the building needs to have an anti-seismic capacity for protecting people during the earthquake and further protect the assets and properties of people residing within the building while retaining the function of the building. In the conventional wall assembly, the inner wall is connected to the outer wall, and the structural strength of the inner wall is weaker than the structural strength of the outer wall. Then, the inner wall of the building is damaged in the earthquake, and the pipelines installed in the inner wall are easily broken. Another aspect is the ever-rising environmental awareness to gradually accomplish energy saving and carbon reduction into daily life. Taiwan is located in the subtropical zone with a hot and humid climate. The interior ambient temperature of the building is normally high. People need to frequently turn on cooling appliances for lowering the interior ambient temperature, so energy saving and carbon reduction cannot be effectively achieved.
To overcome the shortcomings, the present invention provides a composite wall assembly to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
The objective of the invention is to provide a composite wall assembly that may solve the problems that the pipelines installed in the wall assembly of the building are easily broken in the earthquake and the heat from the outdoors cannot be insulated.
The composite wall assembly has an auxiliary wall and an inner wall. The auxiliary wall has a hollow space and a first supporting pillar. The hollow space is formed in the auxiliary wall. The first supporting pillar has multiple first through holes. The first through holes are connected to the hollow space. An outer surface of the first supporting pillar abuts an inner surface of a wall or a ceiling. The inner wall is attached to the auxiliary wall and forms a depositing space. The inner wall has a first wall member, a second wall member, and a second supporting pillar. The first wall member is connected to the hollow space and has a connecting pillar connected to the first supporting pillar. The depositing space is disposed between the first wall member and the second wall member. The second supporting pillar is mounted between the first wall member and the second wall member, is connected to the connecting pillar, and has multiple second through holes. The second through holes are connected to the depositing space.
Furthermore, the first wall member has a connecting pillar. Two sides of the connecting pillar are respectively connected to the first supporting pillar and the second supporting pillar.
The hollow space exists in the inner space of the auxiliary wall and the depositing space exists in the inner space of the inner wall. For security concerns and construction requirements, the pipelines are installed in the hollow space. The auxiliary wall is located between a wall of the building and the inner wall or is located between a ceiling of the building and the inner wall of the building. The auxiliary wall, providing a cushion effect, is able to maintain the pipelines unharmed during earthquakes so that the earthquake-resistance of the building is increased. Transmittance of thermal energy from an outer wall of the building to the inner wall of the composite wall assembly is decreased due to the hollow space of the auxiliary wall, thereby enhancing heat insulation. In summer, the interior ambient temperature of the building therefore maintains low. It saves energy and reduces carbon emissions. In addition, the hollow space of the auxiliary wall provides a sound-proof effect so an indoor cement finish layer is not necessary. The construction time is saved and air pollution is reduced. The auxiliary wall may be recycled to accord with the standard of healthy buildings.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
