Abstract
Description
Technical Field
[0001] The utility model relates to the field of negative carbon technology, in particular to an ultra-low energy consumption house building structure. Background Art
[0002] As the global climate change problem becomes increasingly serious, reducing carbon emissions has become an important task in all fields. As a major energy consumer and carbon emitter, it is of great significance for the construction industry to explore technologies and methods to achieve negative carbon emissions. At present, most buildings have taken some measures to save energy and reduce emissions, such as installing insulation panels on the outside of the walls to balance the indoor temperature, reduce the energy loss required for heating in winter and cooling in summer, thereby improving the energy-saving efficiency of the building itself, and installing renewable energy devices such as solar energy or wind energy on the roof of the building to achieve energy conservation and emission reduction.
[0003] However, it still has some shortcomings. For example, existing building insulation panels are usually external insulation panels installed on the outside of the wall and internal insulation panels installed on the inside of the wall. Although they can balance the indoor temperature to a certain extent, there is still a difference from the ideal effect and it is impossible to achieve complete energy conservation and emission reduction. Existing buildings usually install solar photovoltaic panels on the roof to realize the utilization of renewable energy, but the energy regenerated in actual use is far lower than the daily energy demand, making it difficult to achieve true negative carbon emissions.
[0004] In order to solve the above problems, this application proposes an ultra-low energy consumption house building structure. Utility Model Content

[0008] Preferably, one side outer surface of the PCM energy storage plate is coated with a phase change thermal insulation material, the main component of which is vacuum ceramic micro beads.
[0009] Preferably, the steel bar main body is in two groups and is composed of a plurality of horizontal and vertical steel bars, and the connecting frame is in multiple groups and penetrates through the steel bar main body, so as to fix the insulation board and the steel bar main body.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] See also Figure 1-Figure 3 The utility model provides a technical solution: an ultra-low energy consumption house building structure, including an energy-saving wall 1 and an energy utilization device 2, an insulation board 3 is fixedly installed on the inner side of the energy-saving wall 1, and a PCM energy storage board 4 is detachably installed on the outer side of the energy-saving wall 1, and a connecting frame 5 is fixedly connected to the inner side of the insulation board 3, and the two ends of the connecting frame 5 are respectively connected to a steel body 6, and steel wire meshes 7 are installed on both sides of the steel body 6. The thermal insulation effect of the wall is improved by installing a thickened insulation board 3 on the inner side of the energy-saving wall 1, and the PCM energy storage board 4 is installed on the outer side of the energy-saving wall 1. The PCM energy storage board 4 is used to store and release thermal energy through phase change, thereby absorbing solar radiation heat and human body sensor heat, and releasing the stored thermal energy at room temperature, so as to achieve thermal insulation and energy saving of the wall, thereby achieving energy saving and emission reduction through the building body.
[0021] In this embodiment, Figure 2 Figure 3 As shown, the insulation board 3 is a graphite polystyrene board with a thickness of about 200 mm. The graphite polystyrene board has excellent insulation effect, can effectively isolate heat transfer, and keep the indoor temperature stable, thereby reducing the heat loss of the building, improving the insulation performance of the building, and then reducing the consumption of cold and heat energy, achieving the purpose of energy saving. The thickness of the insulation board 3 is much higher than that of the traditional insulation board, and its insulation effect is better.
[0022] One side outer surface of the PCM energy storage board 4 is coated with phase change insulation material, the main component of which is vacuum ceramic microbeads. The PCM energy storage board 4 stores and releases heat energy through phase change, and then absorbs solar radiation heat and human sensor heat, and releases the stored heat energy at room temperature to achieve wall insulation and energy saving. The steel body 6 is divided into two groups and is composed of a plurality of horizontal and vertical steel bars. The connecting frame 5 is divided into multiple groups and runs through the steel body 6 to fix the insulation board 3 and the steel body 6. The left and right sides of the connecting frame 5 and the insulation board 3 are provided with cavities for pouring concrete. By pouring foam concrete into the cavities on both sides of the insulation board 3, since the foam concrete contains a large number of bubbles and micropores, it has good thermal insulation and is light in weight, which effectively improves the efficiency of building insulation and construction.
[0023] In this embodiment, Figure 1As shown, the energy utilization device 2 is sequentially installed on the outside of the energy-saving wall 1 and is located at the dividing part of each group of floors. By installing the solar panels on the roof of the building and then installing the energy utilization device 2 on the vertical wall, the utilization efficiency of renewable energy is improved. The converted renewable energy can completely replace the required coal, oil, electricity and other energy sources, so that the energy consumption in the building is completely provided by the renewable energy on the site, thereby achieving zero carbon emissions of the building. The energy utilization device 2 is installed at the dividing part of each group of floors, which can avoid the energy utilization device 2 blocking the windows as much as possible, thereby affecting the lighting effect in the building and improving the aesthetics of the exterior wall of the building.
