Abstract
A rain shed without heat bridge in building with very low energy consumption is composed of a main body consisting of steel beams for supporting the rain shed and sandwich toughened glass. The waterproof heat-preservation cornice is built on the outer wall of the building above the awning main body and is higher than the awning top plate by at least 2 cm; the rain shed main body and the building outer wall body are bonded and sealed by using silicone sealant; the concrete balancing weight passes through the built-in fitting and connects the two steel columns that set up in the building outer wall opening part left and right sides, and two steel columns pass through the crossbeam and connect. The rain shed is externally provided with a slope of 3 percent, and double-layer glass is stuck to the lower part of the rain shed to form a water retaining strip of the rain shed main body. The steel diagonal bracing can be lapped between the rectangular steel frame and the double steel columns for supporting the top plate of the canopy to form a triangular stable support. The rain cover without the heat bridge can make the rain cover and the building body relatively independent on the structure system, but mutually engaged on the waterproof system, solve the key node of the heat bridge breaking design of the rain cover at the outlet of the building and achieve the requirement of the rain cover without the heat bridge in the complete building.

Background
The common rain shed on the upper part of the inlet and outlet of the existing domestic building is mainly of a glass fiber reinforced plastic structure and an all-steel structure, and the connection mode with the building main body is mainly of steel structure riveting or welding. On the premise of adopting a conventional heat bridge breaking mode, through finite element analysis, the single-point heat conduction coefficient x of each fixed point is 0.31W/K, and a heat bridge exists to a certain extent. In engineering practice, because the actual steel structure is designed more complicatedly than the ideal design value of a building designer, the support or the sectional area needs to be increased, and the heat insulation plate at the position where the steel beam penetrates out is cut to form a cavity due to overlarge size during installation, the heat bridge effect of the fixed point of the awning is more obvious.
The method is characterized in that the super-low energy consumption building is popularized by great force in China, the method is the main direction of the building industry for a long time in the future, one very important point in the design link is the design without a heat bridge, and the existing rain awning structural form can not meet the design requirement of the super-low energy consumption building which is popularized by great force in China at present.
SUMMERY OF THE UTILITY MODEL
For avoiding the installation heat bridge in the design of traditional canopy, the utility model discloses an independent support formula canopy utilizes steel column and steel bracing to support the girder steel, combines the concrete counter weight of steel column basis part to form self-stabilization's system, assists with the installation node simultaneously, has solved waterproof and connection permanence's problem. The whole system enables the awning steel beam to be completely separated from the wall body, ensures the continuity of wall body heat preservation and achieves the effect of no heat bridge.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a do not have thermal bridge canopy in ultralow energy consumption building, includes canopy main part, waterproof eaves, two steel columns and buries the concrete balancing weight under the canopy step, and canopy main part mainly comprises girder steel and the intermediate layer toughened glass that support canopy. The waterproof heat-preservation cornice is built on the outer wall of the building above the awning main body and is higher than the awning top plate by at least 2 cm; the rain shed main body and the building outer wall body are bonded and sealed by using silicone sealant; the concrete balancing weight passes through the built-in fitting and connects the two steel columns that set up in the building outer wall body opening part left and right sides, and two steel columns pass through the crossbeam and connect, and the crossbeam also is regarded as a limit of the rectangle steel frame that supports the canopy roof simultaneously.
The rain shed is further characterized in that the rain shed body is provided with a slope of 3% to the outside, and double-layer glass is adhered to the lower part of the rain shed body to form a water retaining strip of the rain shed body.
The rain shed is further characterized in that steel diagonal braces are adopted to be lapped between the rectangular steel frame and the double steel columns for supporting the top plate of the rain shed to form a triangular stable support.
The waterproof heat-preservation cornice is further characterized in that an extruded polystyrene board with the thickness of 10cm x 10cm is adopted.
The utility model discloses novel structure, the structure is unique simple, and the practicality is strong, the construction of being convenient for to can realize being connected of disconnected heat bridge with the independent canopy that the double steel post that the molding is graceful falls to the ground with the building subject, realize the no heat bridge design that becomes more meticulous in the building of ultralow energy consumption with minimum cost.

Detailed Description
Fig. 1 is a schematic plan view of the rain shed, showing the installation relationship with the waterproof and heat-insulating strip 3.
Fig. 2 is a sectional node diagram of the rain fly, which mainly shows the positional relationship between the rain fly and the building body.
The awning without the heat bridge comprises an awning main body, a waterproof cornice 3, a double-steel column 7 and a concrete balancing weight 6 buried under the step of the awning. The awning main body mainly comprises a steel beam 1 for supporting the awning and interlayer toughened glass 2;
the waterproof cornice 3 is built on the outer wall of the building above the rain awning main body 2 and is higher than the top plate of the rain awning by at least 2 cm. The waterproof heat-preservation cornice 3 can adopt a 10 cm-10 cm extruded polystyrene board, and can perform waterproof and exterior facing construction along with a building main body to form a permanent component.
The double-layer glass 4 is adhered to the lower part of the rain shed main body to form a water retaining strip of the rain shed main body. The rain shed main body and the building outer wall body are bonded and sealed by using the silicone sealant 5, so that the independent rain shed is relatively independent from the building main body on a structural system, but is mutually meshed on a waterproof system, and the key node of the design of the heat-insulated bridge of the rain shed at the outlet of the building is solved.
The concrete balancing weight 6 is connected with double steel columns 7 arranged on the left side and the right side of the opening of the building outer wall body through embedded parts. The two steel columns are connected through a cross beam, and the cross beam is also used as one side of a rectangular steel frame for supporting the top plate of the canopy.
If the steel diagonal bracing is adopted to be lapped between the rectangular steel frame and the double steel columns for supporting the top plate of the canopy, a triangular stable support is formed. Through increasing the steel bracing overlap joint can utilize the steel bracing and bury the concrete balancing weight under the canopy step and realize the stability of canopy self structure between rectangle steel frame and the double steel post that support the canopy roof, more can satisfy the requirement of the antidetonation of structure self, antidumping.
The heat bridge-free awning used in the ultra-low energy consumption building can enable the awning and the building main body to be relatively independent on a structural system, but the awning and the building main body are mutually meshed on a waterproof system, so that the key node of the heat bridge breaking design of the awning at the outlet of the building is solved, and the fine design requirement of no heat bridge is met completely.
