The utility model discloses a composite building decorative plate which comprises a surface layer, a core layer and a bottom layer. The surface layer, the core layer and the bottom layer are sequentially connected from top to bottom; materials of the surface layer and the bottom layer include but are not limited to metal or non-metal materials. A plurality of groups of built-in grooves are formed in the core layer at equal intervals in a penetrating manner; the top of the bottom layer is integrally connected with multiple sets of reinforcing pieces at equal intervals. The reinforcing pieces are connected into the built-in grooves in an embedded mode, and the tops of the reinforcing pieces are fixedly connected with the bottom of the surface layer. According to the composite building decoration plate, the heat preservation function and the decoration function are integrated together, a novel external wall heat preservation and decoration integrated system is formed, the composite building decoration plate is good in heat preservation effect, and due to the fact that high-quality heat preservation materials and a special composite technology are adopted, the plate has the high heat preservation performance and the high sealing performance; the heat bridge phenomenon and the condensate water problem are effectively prevented, flame spreading and smoke generation can be effectively prevented, and the building safety is improved.

The present invention provides a method for controlling sunshades in public buildings, comprising: establishing a total energy consumption model of air conditioning and lighting that shows the relationship between the energy consumption of electromechanical equipment and sunshade control based on a digital twin model of the public building; establishing a model of the relationship between reader satisfaction and sunshade control based on indoor perceived temperature, indoor light intensity, and building surrounding environment comfort parameters: constructing an energy consumption and satisfaction balance point evaluation function based on a model of total energy consumption of air conditioning and lighting and a model of the relationship between reader satisfaction and sunshade control; formulating a sunshade control strategy based on the energy consumption and satisfaction balance point evaluation function, and improving a historical database, thereby improving the energy-saving effect of the building: reducing energy waste by actively identifying abnormal scenes and processing them in a targeted and timely manner; improving the work efficiency of maintenance personnel: reducing ineffective patrol work; and improving the management level: making scientific decisions by summarizing the collected status data.

The utility model relates to a sunshade system technical field, concretely relates to a V type pottery plate sunshade system. Include: the pallet is multiple, is fixed on curtain wall stand column, pottery plate is set between two adjacent pallets, pottery plate is V-shaped, and the opening is to the side away from curtain wall. In this application, the pallet can support and fix the pottery plate, the pottery plate is V-shaped, and the opening is to the side away from curtain wall, can increase the sunshade area of blocking direct sunlight into the room, and compared with rectangular pottery stick, also has the weight of relatively small, can make the pallet not damage.

The utility model relates to building curtain wall reconstruction technical field discloses a kind of exempt from disassembly sound insulation enhancement structure based on existing glass curtain wall, comprising: composite sound insulation wrapping layer, the composite sound insulation wrapping layer is attached to the original curtain wall column of existing glass curtain wall With the surface of original curtain wall beam, to be used for wrapping original beam column and blocking sound bridge transmission;Damping vibration isolation layer, the damping vibration isolation layer is arranged between composite sound insulation wrapping layer and original curtain wall column / original curtain wall beam, between special sound insulation glass and composite sound insulation wrapping layer, to be used for reducing vibration noise transmission.In the utility model, by the synergistic effect of "composite wrapping layer+special glass+damping vibration isolation+cavity", outdoor traffic noise is effectively reduced, the appearance and stability are maintained using existing curtain wall structure, the curtain wall K value can also be reduced, the adaptability is stronger and the service life is longer, and large equipment is not needed in construction.

The application provides a gold marker implantation position recommendation method and system, relates to the technical field of image-guided radiotherapy, and comprises the following steps: acquiring CT image data of a patient; determining a plurality of gold marker implantation points of a gold marker based on the CT image data; combining the gold marker implantation points according to a preset aggregation rule, and constructing a plurality of gold marker point sets; for each gold marker point set, respectively evaluating a three-dimensional geometric stability index and a two-dimensional observable stability index thereof; combining a preset evaluation rule and the geometric stability index and the observable stability index corresponding to each gold marker point set, and screening an optimal gold marker point set from all the gold marker point sets; and taking the gold marker implantation points in the optimal gold marker point set as recommended gold marker implantation positions. Through the quantitative evaluation of the geometric stability and the observable stability of the gold marker based on the CT image before implantation, the optimal implantation point is actively recommended, so that the distribution degeneration problem is eliminated, the rework after implantation is avoided, and the tracking accuracy and the treatment efficiency are ensured from the source.
